Description

　本開示は、ＲＦＩＤ機能付き容器に関する。特に、本開示は、誘導電磁界または電波によって、非接触でデータ通信を行うＲＦＩＤ（Radio Frequency Identification）技術を利用したＲＦＩＤ機能付き容器に関する。 The present disclosure relates to a container with RFID function. In particular, the present disclosure relates to a container with an RFID function that utilizes RFID (Radio Frequency Identification) technology for non-contact data communication using an induced electromagnetic field or radio waves.
　従来、無線通信デバイスであるＲＦＩＤタグを容器に付すことで、容器内の商品の管理をすることが考えられている。ＲＦＩＤタグは、ＲＦＩＣ（Radio-Frequency Integrated Circuit）素子と共に、アンテナパターン等の金属材料が紙材や、樹脂材等の絶縁基板上に形成されている。しかしながら、容器の外面に金属膜が形成されていると、ＲＦＩＤタグが影響を受けて通信ができなくなる。 Conventionally, it has been considered to manage the products in containers by attaching RFID tags, which are wireless communication devices, to the containers. In an RFID tag, together with an RFIC (Radio-Frequency Integrated Circuit) element, a metal material such as an antenna pattern is formed on an insulating substrate such as paper or resin. However, if a metal film is formed on the outer surface of the container, the RFID tag is affected and communication becomes impossible.
　上記のようなＲＦＩＤタグ付き容器において、特許文献１には、意匠性を損なわないように容器の一部に形成された金属に対応可能なＲＦＩＤタグを設けた構成が提案されている。 In the RFID tag-equipped container as described above, Patent Document 1 proposes a configuration in which an RFID tag is provided that is compatible with metal formed on a part of the container so as not to impair the design.

[1.1 Embodiment 1]
[1.1.1 Configuration]
FIG. 1 is an exploded perspective view of a configuration example of a container 100 with RFID function according to Embodiment 1. FIG. The RFID function-equipped container 100 of FIG. 1 is used, for example, in a system for identifying and managing products by wireless communication. The RFID function-equipped container 100 of FIG. 1 is traded as a product while containing the content N100. The content N100 is, for example, an article for commercial transactions. Contents N100 can be liquid, solid, sol, gel, or combinations thereof. Examples of contents N100 include food, medicines, medical or orthodontic appliances, and the like. Foods include foods that can be provided in a container, such as yogurt, pudding, and instant foods. Medical or corrective devices include contact lenses.
　図１のＲＦＩＤ機能付き容器１００は、本体１１０と、蓋１２０と、ＲＦＩＤモジュール１３０とを備える。 The RFID function-equipped container 100 in FIG.
　図１の本体１１０は、内容物Ｎ１００用の収容空間１１１を有する。本体１１０は、電気絶縁性を有する。本体１１０は、例えば、紙、樹脂材料、又はガラス等の誘電体材料から形成される。樹脂材料は、例えば、発泡スチロールを含む。図１の本体１１０は、有底の筒状部１１２と、フランジ部１１３とを有する。筒状部１１２は、収容空間１１１を規定する。図１の筒状部１１２は、円筒形状である。フランジ部１１３は、収容空間１１１の開口縁部から外方に突出する。図１のフランジ部１１３の外形形状は、正方形状である。 The main body 110 of FIG. 1 has an accommodation space 111 for the contents N100. The main body 110 has electrical insulation. The main body 110 is made of dielectric material such as paper, resin material, or glass, for example. The resin material includes expanded polystyrene, for example. The main body 110 of FIG. 1 has a bottomed tubular portion 112 and a flange portion 113 . The tubular portion 112 defines the accommodation space 111 . The tubular portion 112 in FIG. 1 is cylindrical. The flange portion 113 protrudes outward from the opening edge of the housing space 111 . The outer shape of the flange portion 113 in FIG. 1 is square.
　図１の蓋１２０は、本体１１０に、収容空間１１１の開口を覆うように取り付けられる。本実施の形態において、蓋１２０は、本体１１０に剥離可能に取り付けられる。蓋１２０は、本体１１０の収容空間１１１から内容物Ｎ１００を取り出す際に、本体１１０から剥離される。蓋１２０は全体的に可撓性を有する。蓋１２０は、接着剤により本体１１０の収容空間１１１の開口の周縁部分に取り付けられる。図１では、蓋１２０は、本体１１０のフランジ部１１３に接着剤で取り付けられる。接着剤は、蓋１２０においてフランジ部１１３に対向する領域に塗布される。 The lid 120 in FIG. 1 is attached to the main body 110 so as to cover the opening of the accommodation space 111 . In this embodiment, lid 120 is releasably attached to main body 110 . The lid 120 is peeled off from the main body 110 when the content N100 is taken out from the housing space 111 of the main body 110 . Lid 120 is generally flexible. The lid 120 is attached to the periphery of the opening of the housing space 111 of the main body 110 with an adhesive. In FIG. 1, the lid 120 is adhesively attached to the flange portion 113 of the body 110 . The adhesive is applied to a region of lid 120 facing flange portion 113 .
　蓋１２０は、基材１２１と、金属膜１２２とを含む。基材１２１は、収容空間１１１の開口を覆う。特に、基材１２１は、収容空間１１１の開口及びフランジ部１１３を全体的に覆う。基材１２１の外形形状は、正方形状である。基材１２１は、例えば、紙又はプラスチック等の誘電体材料から形成される。金属膜１２２は、本体１１０の収容空間１１１の開口を覆う。金属膜１２２は、収容空間１１１の開口及びフランジ部１１３を全体的に覆う。金属膜１２２は、基材１２１における本体１１０側の面にある。金属膜１２２は、外部要因に起因する内容物の変化を防止する作用を有し得る。このように、金属膜１２２は、収容空間１１１の開口を覆うことで、内容物Ｎ１００を保護する。金属膜１２２の材料としては、アルミニウム及びアルミニウムを含む合金が挙げられる。 The lid 120 includes a base material 121 and a metal film 122. The base material 121 covers the opening of the accommodation space 111 . In particular, the base material 121 entirely covers the opening of the accommodation space 111 and the flange portion 113 . The outer shape of the base material 121 is square. Substrate 121 is formed from a dielectric material such as paper or plastic, for example. The metal film 122 covers the opening of the accommodation space 111 of the main body 110 . The metal film 122 entirely covers the opening of the housing space 111 and the flange portion 113 . The metal film 122 is on the surface of the base material 121 on the main body 110 side. The metal film 122 can act to prevent changes in the contents caused by external factors. Thus, the metal film 122 protects the content N100 by covering the opening of the accommodation space 111. FIG. Materials for the metal film 122 include aluminum and alloys containing aluminum.
　図２は、蓋１２０の底面図である。図２に示すように、金属膜１２２は、複数の部位に分割される。より詳細には、金属膜１２２は、金属膜１２２の四辺に対応する第１～第４辺部１２２ａ～１２２ｄと、収容空間１１１の開口を覆う中央部１２２ｅとに分割される。中央部１２２ｅは、金属膜１２２において収容空間１１１の開口を覆う所定領域Ｒ１００を含む。金属膜１２２において、第１～第４辺部１２２ａ～１２２ｄと中央部１２２ｅとは互いに電気的に分離されている。第１～第４辺部１２２ａ～１２２ｄは、ＲＦＩＤモジュール１３０のためのアンテナパターンとして用いることができる。金属膜１２２では、第１～第４辺部１２２ａ～１２２ｄのうちの隣接する２つをＲＦＩＤモジュール１３０のためのアンテナパターンとして用いることができる。つまり、ＲＦＩＤモジュール１３０を蓋１２０の四隅のいずれに設定してもよい。そのため、ＲＦＩＤモジュール１３０の蓋１２０への配置の自由度が向上する。図２では、第１及び第２辺部１２２ａ，１２２ｂが、互いに電気的に独立した第１及び第２アンテナパターンを構成する。本実施の形態では、第１辺部１２２ａを第１アンテナパターン１２２ａといい、第２辺部１２２ｂを第２アンテナパターン１２２ｂということがある。 2 is a bottom view of the lid 120. FIG. As shown in FIG. 2, the metal film 122 is divided into multiple parts. More specifically, the metal film 122 is divided into first to fourth side portions 122 a to 122 d corresponding to the four sides of the metal film 122 and a center portion 122 e covering the opening of the accommodation space 111 . The central portion 122e includes a predetermined region R100 covering the opening of the accommodation space 111 in the metal film 122. As shown in FIG. In the metal film 122, the first to fourth side portions 122a to 122d and the central portion 122e are electrically isolated from each other. The first through fourth sides 122 a - 122 d can be used as antenna patterns for the RFID module 130 . Adjacent two of the first to fourth side portions 122 a to 122 d of the metal film 122 can be used as antenna patterns for the RFID module 130 . That is, the RFID module 130 may be set at any of the four corners of the lid 120 . Therefore, the degree of freedom in arranging the RFID module 130 on the lid 120 is improved. In FIG. 2, the first and second sides 122a and 122b form first and second antenna patterns that are electrically independent of each other. In this embodiment, the first side portion 122a may be referred to as the first antenna pattern 122a, and the second side portion 122b may be referred to as the second antenna pattern 122b.
　金属膜１２２は、金属膜１２２に形成されるスリット１２３により第１～第４辺部１２２ａ～１２２ｄと、収容空間１１１の開口を覆う中央部１２２ｅとに分割される。したがって、第１及び第２アンテナパターン１２２ａ，１２２ｂの形状は、金属膜１２２に形成されるスリット１２３により規定される。スリット１２３は、金属膜１２２において本体１１０の収容空間１１１の開口を覆う所定領域Ｒ１００を避けて配置される。これにより、金属膜１２２による内容物Ｎ１００の保護機能に影響を及ぼすことなく、アンテナパターン１２２ａ，１２２ｂを設けることができる。図２のスリット１２３は、枠部１２３ａと、第１～第４延長部１２３ｂ－１～１２３ｂ－４とを含む。枠部１２３ａは、所定領域Ｒ１００を囲う矩形枠状である。枠部１２３ａの四辺は金属膜１２２の四辺にそれぞれ平行している。第１～第４延長部１２３ｂ－１～１２３ｂ－４の各々は、枠部１２３ａの角から金属膜１２２の角のうち最も近接する角に延びている。第１及び第４延長部１２３ｂ－１，１２３ｂ－４は蓋１２０の同一の対角線上に位置する。第２及び第３延長部１２３ｂ－２，１２３ｂ－３は蓋１２０の同一の対角線上に位置する。スリット１２３において、枠部１２３ａは、収容空間１１１の開口を囲うように形成されて所定領域Ｒ１００から第１及び第２アンテナパターン１２２ａ，１２２ｂを電気的に分離する第１部位である。第１延長部１２３ｂ－１は、収容空間１１１の開口の縁部に形成されて第１及び第２アンテナパターン１２２ａ，１２２ｂ間を電気的に分離する第２部位である。なお、スリット１２３は、金属膜１２２を貫通するが基材１２１を貫通しない。 The metal film 122 is divided by slits 123 formed in the metal film 122 into first to fourth side portions 122 a to 122 d and a central portion 122 e covering the opening of the accommodation space 111 . Therefore, the shapes of the first and second antenna patterns 122 a and 122 b are defined by the slits 123 formed in the metal film 122 . The slit 123 is arranged in the metal film 122 so as to avoid the predetermined region R100 covering the opening of the accommodation space 111 of the main body 110 . Accordingly, the antenna patterns 122a and 122b can be provided without affecting the function of the metal film 122 to protect the content N100. The slit 123 of FIG. 2 includes a frame portion 123a and first to fourth extension portions 123b-1 to 123b-4. The frame portion 123a has a rectangular frame shape surrounding the predetermined region R100. The four sides of the frame portion 123a are parallel to the four sides of the metal film 122, respectively. Each of the first to fourth extensions 123b-1 to 123b-4 extends from the corner of the frame 123a to the corner of the metal film 122 that is the closest. The first and fourth extensions 123b-1 and 123b-4 are positioned on the same diagonal line of the lid 120. As shown in FIG. The second and third extensions 123b-2 and 123b-3 are positioned on the same diagonal line of the lid 120. As shown in FIG. In the slit 123, the frame portion 123a is a first portion that is formed to surround the opening of the housing space 111 and electrically separates the first and second antenna patterns 122a and 122b from the predetermined region R100. The first extension part 123b-1 is a second part formed at the edge of the opening of the accommodation space 111 and electrically separating the first and second antenna patterns 122a and 122b. Note that the slit 123 penetrates the metal film 122 but does not penetrate the base material 121 .
　ＲＦＩＤモジュール１３０は、通信周波数（キャリア周波数）を有する高周波信号で無線通信（送受信）するように構成された無線通信デバイスである。ＲＦＩＤモジュール１３０は、例えば、ＵＨＦ帯の通信用の周波数を有する高周波信号で無線通信するよう構成されている。ここでＵＨＦ帯とは、８６０ＭＨｚから９６０ＭＨｚの周波数帯域である。 The RFID module 130 is a wireless communication device configured to wirelessly communicate (transmit and receive) using high-frequency signals having a communication frequency (carrier frequency). The RFID module 130 is configured, for example, to perform wireless communication using a high-frequency signal having a frequency for communication in the UHF band. Here, the UHF band is a frequency band from 860 MHz to 960 MHz.
　図２に示すように、ＲＦＩＤモジュール１３０は、蓋１２０における所定領域Ｒ１００の外側にあって金属膜１２２に結合される。つまり、ＲＦＩＤモジュール１３０は、蓋１２０における収容空間１１１の開口の外側にあって金属膜１２２に結合される。収容空間１１１の開口の外側にあるとは、収容空間１１１の深さ方向に直交する平面において収容空間１１１と重ならないことをいう。ＲＦＩＤモジュール１３０は、蓋１２０における本体１１０側（つまり、蓋１２０の裏側）にある。特に、ＲＦＩＤモジュール１３０は、蓋１２０において本体１１０のフランジ部１１３と対向する部位にある。ＲＦＩＤ機能付き容器１００の輸送時又は陳列時等においてＲＦＩＤ機能付き容器１００を重ねた場合、本体１１０の筒状部１１２が重なる。図３は、ＲＦＩＤ機能付き容器１００を重ねた状態を示す概略図である。ＲＦＩＤ機能付き容器１００では、上述したように、ＲＦＩＤモジュール１３０は、蓋１２０において本体１１０のフランジ部１１３と対向する部位にある。そのため、ＲＦＩＤモジュール１３０は、ＲＦＩＤモジュール１３０が蓋１２０において本体１１０の収容空間１１１と重なる部位にある場合に比べて、別のＲＦＩＤ機能付き容器１００からの影響、特に、内容物Ｎ１００からの影響を受けにくい。そのため、本実施の形態のＲＦＩＤ機能付き容器１００は、ＲＦＩＤ機能付き容器１００を重ねた場合、本体１１０の筒状部１１２が重なるので、ＲＦＩＤモジュール１３０の機能を損ねる可能性を低減できる。 As shown in FIG. 2, the RFID module 130 is outside the predetermined region R100 on the lid 120 and is coupled to the metal film 122. As shown in FIG. That is, the RFID module 130 is outside the opening of the housing space 111 in the lid 120 and coupled to the metal film 122 . Being outside the opening of the accommodation space 111 means not overlapping the accommodation space 111 on a plane orthogonal to the depth direction of the accommodation space 111 . The RFID module 130 is on the body 110 side of the lid 120 (that is, on the back side of the lid 120). In particular, the RFID module 130 is located at a portion of the lid 120 facing the flange portion 113 of the main body 110 . When the RFID function-equipped container 100 is stacked during transportation or display of the RFID function-equipped container 100, the tubular portion 112 of the main body 110 overlaps. FIG. 3 is a schematic diagram showing a state in which the RFID function-equipped containers 100 are stacked. In the RFID function-equipped container 100 , as described above, the RFID module 130 is located at a portion of the lid 120 facing the flange portion 113 of the main body 110 . Therefore, the RFID module 130 is less affected by another container 100 with RFID function, particularly by the contents N100, than when the RFID module 130 is located in the lid 120 overlapping the housing space 111 of the main body 110.

　図１のＲＦＩＤ機能付き容器１００では、ＲＦＩＤモジュール１３０と金属膜１２２の第１及び第２アンテナパターン１２２ａ，１２２ｂとが、通信回路を構成する。金属膜１２２の第１及び第２アンテナパターン１２２ａ，１２２ｂは、ＲＦＩＤモジュール１３０に対して、ダイポールアンテナとして機能する。 In the RFID function-equipped container 100 of FIG. 1, the RFID module 130 and the first and second antenna patterns 122a and 122b of the metal film 122 constitute a communication circuit. The first and second antenna patterns 122 a and 122 b of the metal film 122 function as dipole antennas for the RFID module 130 .
　次に、図７を参照して、図１のＲＦＩＤ機能付き容器１００の通信回路の回路構成について説明する。図７は、ＲＦＩＤ機能付き容器１００の回路構成の一例の回路図である。 Next, the circuit configuration of the communication circuit of the container 100 with RFID function in FIG. 1 will be described with reference to FIG. FIG. 7 is a circuit diagram of an example of the circuit configuration of the container 100 with RFID function.
　図７に示すように、ＲＦＩＤモジュール１３０内において、第１電流経路ＣＰ１は、ＬＣ並列共振回路である並列共振回路ＲＣ１の一部であり、通信周波数の電波に対してマッチングしているので、通信周波数の電波を金属膜１２２が受信すると、ＲＦＩＣ素子１３４に電流が流れる。 As shown in FIG. 7, in the RFID module 130, the first current path CP1 is part of the parallel resonant circuit RC1, which is an LC parallel resonant circuit, and is matched to the radio waves of the communication frequency. When the metal film 122 receives radio waves of the frequency, a current flows through the RFIC element 134 .
　ＲＦＩＤモジュール１３０は、並列共振回路ＲＣ１を有する。並列共振回路ＲＣ１は、第１インダクタンス素子Ｌ１、ＲＦＩＣ素子１３４、第２インダクタンス素子Ｌ２、及び、第３インダクタンス素子Ｌ３で構成されるループ回路である。 The RFID module 130 has a parallel resonant circuit RC1. The parallel resonant circuit RC1 is a loop circuit composed of the first inductance element L1, the RFIC element 134, the second inductance element L2, and the third inductance element L3.
　上述したように、ＲＦＩＤモジュール１３０の第１及び第２電極１３１，１３２は、第１及び第２アンテナパターン１２２ａ，１２２ｂにそれぞれ容量結合される。第１電極１３１と第１アンテナパターン１２２ａとの間の容量成分Ｃ１は、第１アンテナパターン１２２ａ、第１電極１３１、接着層１３９、及び保護フィルム１３６で構成される。第２電極１３２と第２アンテナパターン１２２ｂとの間の容量成分Ｃ２は、第２アンテナパターン１２２ｂ、第２電極１３２、接着層１３９、及び保護フィルム１３６で構成される。第１アンテナパターン１２２ａは、インダクタンス成分を有し、第４インダクタンス素子Ｌ４として作用する。第２アンテナパターン１２２ｂは、インダクタンス成分を有し、第５インダクタンス素子Ｌ５として作用する。 As described above, the first and second electrodes 131, 132 of the RFID module 130 are capacitively coupled to the first and second antenna patterns 122a, 122b, respectively.

A capacitive component C2 between the second electrode 132 and the second antenna pattern 122b is composed of the second antenna pattern 122b, the second electrode 132, the adhesive layer 139, and the protective film 136. FIG. The first antenna pattern 122a has an inductance component and acts as a fourth inductance element L4. The second antenna pattern 122b has an inductance component and acts as a fifth inductance element L5.
　並列共振回路ＲＣ１は、通信周波数における電波に対してインピーダンス整合してＬＣ並列共振するように設計されている。そのため、並列共振回路ＲＣ１は、通信周波数である固有の共振周波数の電磁波による電流をＲＦＩＣ素子１３４に伝送するフィルタ回路として作用する。これにより、通信周波数でＲＦＩＣ素子１３４とマッチングしており、通信周波数におけるＲＦＩＤモジュール１３０の通信距離を確保することができる。 The parallel resonant circuit RC1 is designed to perform LC parallel resonance with impedance matching for radio waves at communication frequencies. Therefore, the parallel resonant circuit RC1 acts as a filter circuit that transmits to the RFIC element 134 the current due to the electromagnetic waves of the inherent resonant frequency, which is the communication frequency. Thereby, the communication frequency is matched with the RFIC element 134, and the communication distance of the RFID module 130 at the communication frequency can be secured.

It comprises a lid 120 and an RFID module 130 having first and second electrodes 131 , 132 attached to the lid 120 so as to be outside the opening of the receiving space 111 and coupled to the metal film 122 .
　ＲＦＩＤ機能付き容器１００では、蓋１２０の金属膜１２２にＲＦＩＤモジュール１３０が結合されることで、ＲＦＩＤタグとしての機能が実現される。内容物Ｎ１００の保護等のために蓋１２０に形成される金属膜１２２を利用するから、ＲＦＩＤ機能のためだけにアンテナ等を別途設ける必要がない。ＲＦＩＤモジュール１３０は、蓋１２０における収容空間１１１の開口の外側にあるから、意図せずにＲＦＩＤモジュール１３０が蓋１２０から脱落しても、ＲＦＩＤモジュール１３０が内容物Ｎ１００に混入される可能性を低減できる。このように、本実施の形態のＲＦＩＤ機能付き容器１００は、内容物Ｎ１００を収容する本体１１０に金属膜１２２を有する蓋１２０が取り付けられる容器において、意匠性の低減を抑制しつつもＲＦＩＤモジュール１３０が内容物Ｎ１００に混入する可能性を低減できる。 In the RFID function-equipped container 100, the function as an RFID tag is realized by connecting the RFID module 130 to the metal film 122 of the lid 120. Since the metal film 122 formed on the lid 120 is used to protect the contents N100, etc., there is no need to separately provide an antenna or the like just for the RFID function. Since the RFID module 130 is located outside the opening of the housing space 111 in the lid 120, even if the RFID module 130 falls off the lid 120 unintentionally, the possibility of the RFID module 130 being mixed with the contents N100 is reduced. can.

The RFID module 130 is on the lid 120 such that the first and second electrodes 131, 132 are coupled to the antenna patterns (first and second antenna patterns 122a, 122b). This configuration can improve the efficiency of wireless communication in the RFID module 130 because the metal film 122 has an antenna pattern.
　ＲＦＩＤ機能付き容器１００において、アンテナパターンは、互いに電気的に独立した第１及び第２アンテナパターン１２２ａ，１２２ｂを含む。ＲＦＩＤモジュール１３０は、第１及び第２電極１３１，１３２が第１及び第２アンテナパターン１２２ａ，１２２ｂにそれぞれ結合されるように、蓋１２０にある。この構成は、ダイポールアンテナを形成できる。 In the RFID function-equipped container 100, the antenna patterns include first and second antenna patterns 122a and 122b that are electrically independent of each other. The RFID module 130 is on the lid 120 such that the first and second electrodes 131, 132 are respectively coupled to the first and second antenna patterns 122a, 122b. This configuration can form a dipole antenna.
　ＲＦＩＤ機能付き容器１００において、第１及び第２アンテナパターン１２２ａ，１２２ｂの形状は、金属膜１２２に形成されるスリット１２３により規定される。スリット１２３は、金属膜１２２において収容空間１１１の開口を覆う所定領域Ｒ１００を避けて配置される。この構成は、金属膜１２２による内容物Ｎ１００の保護機能に影響を及ぼすことなく、第１及び第２アンテナパターン１２２ａ，１２２ｂを設けることができる。 In the RFID function-equipped container 100 , the shapes of the first and second antenna patterns 122 a and 122 b are defined by slits 123 formed in the metal film 122 . The slit 123 is arranged in the metal film 122 so as to avoid the predetermined region R100 covering the opening of the accommodation space 111 . This configuration allows provision of the first and second antenna patterns 122a and 122b without affecting the protection function of the contents N100 by the metal film 122. FIG.
　ＲＦＩＤ機能付き容器１００において、スリット１２３は、収容空間１１１の開口を囲うように形成されて所定領域Ｒ１００から第１及び第２アンテナパターン１２２ａ，１２２ｂを電気的に分離する第１部位１２３ａと、収容空間１１１の開口の縁部に形成されて第１及び第２アンテナパターン１２２ａ，１２２ｂ間を電気的に分離する第２部位１２３ｂ－１～１２３ｂ－４とを含む。この構成は、第１及び第２アンテナパターン１２２ａ，１２２ｂが内容物Ｎ１００により影響を受ける可能性を低減できる。 In the RFID function-equipped container 100, the slit 123 is formed so as to surround the opening of the accommodation space 111 and electrically separates the first and second antenna patterns 122a and 122b from the predetermined region R100. and second portions 123b-1 to 123b-4 formed at the edge of the opening of the space 111 to electrically isolate the first and second antenna patterns 122a and 122b. This configuration can reduce the possibility that the first and second antenna patterns 122a, 122b are affected by the content N100.
　ＲＦＩＤ機能付き容器１００において、本体１１０は、収容空間１１１の開口縁部から外方に突出するフランジ部１１３を有する。ＲＦＩＤモジュール１３０は、蓋１２０においてフランジ部１１３と対向する部位にある。この構成は、ＲＦＩＤ機能付き容器１００を重ねた場合に、ＲＦＩＤモジュール１３０の機能を損ねる可能性を低減できる。 In the RFID function-equipped container 100 , the main body 110 has a flange portion 113 that protrudes outward from the opening edge of the accommodation space 111 . The RFID module 130 is located at a portion of the lid 120 facing the flange portion 113 . This configuration can reduce the possibility of impairing the function of the RFID module 130 when the containers 100 with RFID function are stacked.
　ＲＦＩＤ機能付き容器１００において、蓋１２０は、金属膜１２２を覆う保護膜１２４を有する。ＲＦＩＤモジュール１３０は、保護膜１２４と金属膜１２２との間にある。この構成は、ＲＦＩＤモジュール１３０が蓋１２０から脱落する可能性を低減できる。 In the RFID function-equipped container 100 , the lid 120 has a protective film 124 that covers the metal film 122 . RFID module 130 is between protective membrane 124 and metal membrane 122 . This configuration can reduce the likelihood that RFID module 130 will fall off lid 120 .
　ＲＦＩＤ機能付き容器１００において、ＲＦＩＤモジュール１３０は、蓋１２０における本体１１０側にある。この構成は、ＲＦＩＤ機能付き容器１００の意匠性が損なわれにくくなる。この構成は、ＲＦＩＤモジュール１３０が脱落しにくくなる。 In the RFID function-equipped container 100 , the RFID module 130 is on the main body 110 side of the lid 120 . This configuration makes it difficult for the design of the container 100 with RFID function to be impaired. This configuration makes it difficult for the RFID module 130 to fall off.
　ＲＦＩＤ機能付き容器１００において、ＲＦＩＤモジュール１３０は、ＲＦＩＣ素子１３４と、通信周波数である固有の共振周波数の電磁波による電流をＲＦＩＣ素子１３４に伝送するフィルタ回路ＲＣ１とを備える。第１電極１３１及び第２電極１３２は、フィルタ回路ＲＣ１に接続される。この構成は、通信周波数でＲＦＩＣ素子１３４と金属膜１２２とがマッチングしており、通信周波数におけるＲＦＩＤモジュール１３０の通信距離を確保することができる。 In the RFID function-equipped container 100, the RFID module 130 includes an RFIC element 134 and a filter circuit RC1 that transmits to the RFIC element 134 a current generated by electromagnetic waves having a unique resonance frequency, which is the communication frequency. The first electrode 131 and the second electrode 132 are connected to the filter circuit RC1. In this configuration, the RFIC element 134 and the metal film 122 are matched at the communication frequency, and the communication distance of the RFID module 130 at the communication frequency can be secured.

Embodiment 1 is not limited to the above configuration. Embodiment 1 can be modified in various ways according to the design and the like, as long as the problem can be achieved. Modifications of the first embodiment are listed below. Modifications described below can be applied in combination as appropriate.
　［１．１．３．１　変形例１］
　図８は、実施の形態１の変形例１のＲＦＩＤ機能付き容器の蓋１２０Ａの構成例の底面図である。蓋１２０Ａは、スリット１２３Ａが形成された金属膜１２２Ａを含む。図８のスリット１２３Ａは、金属膜１２２Ａにおいて本体１１０の収容空間１１１の開口を覆う所定領域Ｒ１００を避けて配置される。図８のスリット１２３Ａは、図２のスリット１２３とは形状が異なる。図８のスリット１２３Ａは、枠部１２３ａと、第１及び第４延長部１２３ｂ－１，１２３ｂ－４とを含む。スリット１２３Ａは、スリット１２３とは異なり、第２及び第３延長部１２３ｂ－２，１２３ｂ－３を含んでいない。 [1.1.3.1 Modification 1]
FIG. 8 is a bottom view of a configuration example of lid 120A of the container with RFID function according to Modification 1 of Embodiment 1. As shown in FIG. Lid 120A includes metal film 122A having slit 123A formed therein. The slit 123A in FIG. 8 is arranged in the metal film 122A so as to avoid the predetermined region R100 covering the opening of the accommodation space 111 of the main body 110. As shown in FIG. A slit 123A in FIG. 8 has a different shape from the slit 123 in FIG. The slit 123A in FIG. 8 includes a frame portion 123a and first and fourth extension portions 123b-1 and 123b-4. Unlike slit 123, slit 123A does not include second and third extensions 123b-2 and 123b-3.
　スリット１２３Ａにより、金属膜１２２Ａは、金属膜１２２Ａの四辺の隣接する２つに対応する第１辺部１２２ｆと、金属膜１２２Ａの四辺の隣接する残りの２つに対応する第２辺部１２２ｇと、収容空間１１１の開口を覆う中央部１２２ｅとに分割される。金属膜１２２Ａにおいて、第１及び第２辺部１２２ｆ，１２２ｇと中央部１２２ｅとは互いに電気的に分離されている。第１及び第２辺部１２２ｆ，１２２ｇは、ＲＦＩＤモジュール１３０のためのアンテナパターンとして用いることができる。図８では、第１及び第２辺部１２２ｆ，１２２ｇが、互いに電気的に独立した第１及び第２アンテナパターンを構成する。以下では、第１辺部１２２ｆを第１アンテナパターン１２２ｆといい、第２辺部１２２ｇを第２アンテナパターン１２２ｇということがある。 With the slits 123A, the metal film 122A is divided into first side portions 122f corresponding to two adjacent four sides of the metal film 122A and second side portions 122g corresponding to the remaining two adjacent four sides of the metal film 122A. , and a central portion 122 e that covers the opening of the accommodation space 111 . In the metal film 122A, the first and second side portions 122f and 122g and the central portion 122e are electrically isolated from each other. The first and second sides 122f, 122g can be used as antenna patterns for the RFID module 130. FIG. In FIG. 8, the first and second side portions 122f and 122g form electrically independent first and second antenna patterns. Hereinafter, the first side portion 122f may be referred to as the first antenna pattern 122f, and the second side portion 122g may be referred to as the second antenna pattern 122g.
　ＲＦＩＤモジュール１３０は、蓋１２０Ａにおいて、スリット１２３Ａの第１延長部１２３ｂ－１を跨ぐように金属膜１２２Ａに結合される。より詳細には、ＲＦＩＤモジュール１３０は、第１及び第２電極１３１，１３２が第１及び第２アンテナパターン１２２ｆ，１２２ｇにそれぞれ結合されるように、蓋１２０Ａにある。第１及び第２電極１３１，１３２は、第１及び第２アンテナパターン１２２ｆ，１２２ｇにそれぞれ容量結合される。 The RFID module 130 is coupled to the metal film 122A in the lid 120A so as to straddle the first extension 123b-1 of the slit 123A. More specifically, RFID module 130 resides on lid 120A such that first and second electrodes 131, 132 are coupled to first and second antenna patterns 122f, 122g, respectively. The first and second electrodes 131, 132 are capacitively coupled to the first and second antenna patterns 122f, 122g, respectively.
　図８の蓋１２０Ａでは、図２の蓋１２０に比べて、アンテナパターンを長くすることができる。これによって、アンテナパターンの長さの自由度が向上する。そのため、ＲＦＩＤモジュール１３０の通信周波数に対応する波長に対して適した長さにアンテナパターンの長さを設定できる可能性が高くなる。ＲＦＩＤモジュール１３０の通信周波数に対応する波長に対して適した長さは、例えば、ＲＦＩＤモジュール１３０の通信周波数に対応する波長の１／２である。 In the lid 120A of FIG. 8, the antenna pattern can be made longer than in the lid 120 of FIG. This improves the degree of freedom for the length of the antenna pattern. Therefore, it is more likely that the length of the antenna pattern can be set to a length suitable for the wavelength corresponding to the communication frequency of the RFID module 130 . A suitable length for the wavelength corresponding to the communication frequency of RFID module 130 is, for example, ½ of the wavelength corresponding to the communication frequency of RFID module 130 .
　［１．１．３．２　変形例２］
　図９は、実施の形態１の変形例２のＲＦＩＤ機能付き容器の蓋１２０Ｂの構成例の底面図である。蓋１２０Ｂは、スリット１２３Ｂが形成された金属膜１２２Ｂを含む。図９のスリット１２３Ｂは、金属膜１２２Ｂにおいて本体１１０の収容空間１１１の開口を覆う所定領域Ｒ１００を避けて配置される。図９のスリット１２３Ｂは、図２のスリット１２３とは形状が異なる。図９のスリット１２３Ｂは、枠部１２３ａと、第１延長部１２３ｂ－１とを含む。スリット１２３Ｂは、スリット１２３とは異なり、第２～第４延長部１２３ｂ－２～１２３ｂ－４を含んでいない。 [1.1.3.2 Modification 2]
FIG. 9 is a bottom view of a configuration example of lid 120B of a container with an RFID function according to Modification 2 of Embodiment 1. FIG. Lid 120B includes metal film 122B having slit 123B formed therein. The slit 123B in FIG. 9 is arranged in the metal film 122B so as to avoid the predetermined region R100 covering the opening of the housing space 111 of the main body 110. As shown in FIG. A slit 123B in FIG. 9 has a different shape from the slit 123 in FIG. The slit 123B in FIG. 9 includes a frame portion 123a and a first extension portion 123b-1. Unlike slit 123, slit 123B does not include second through fourth extensions 123b-2 through 123b-4.
　スリット１２３Ｂにより、金属膜１２２Ｂは、金属膜１２２Ａの四辺に対応する周辺部１２２ｈと、収容空間１１１の開口を覆う中央部１２２ｅとに分割される。金属膜１２２Ｂにおいて、周辺部１２２ｈと中央部１２２ｅとは互いに電気的に分離されている。周辺部１２２ｈは、中央部１２２ｅを囲う形状であるが、第１延長部１２３ｂ－１において分離されている。これによって、周辺部１２２ｈは、第１延長部１２３ｂ－１を挟んで対向する第１及び第２端１２２ｈａ，１２２ｈｂを有する。周辺部１２２ｈは、ＲＦＩＤモジュール１３０のためのループアンテナパターンとして用いることができる。以下では、周辺部１２２ｈをループアンテナパターン１２２ｈということがある。 The slit 123B divides the metal film 122B into a peripheral portion 122h corresponding to the four sides of the metal film 122A and a central portion 122e covering the opening of the accommodation space 111. In metal film 122B, peripheral portion 122h and central portion 122e are electrically isolated from each other. The peripheral portion 122h has a shape surrounding the central portion 122e, but is separated at the first extension portion 123b-1. Accordingly, the peripheral portion 122h has first and second ends 122ha and 122hb facing each other across the first extension portion 123b-1. Periphery 122 h can be used as a loop antenna pattern for RFID module 130 . Below, peripheral part 122h may be called loop antenna pattern 122h.
　ＲＦＩＤモジュール１３０は、蓋１２０Ｂにおいて、スリット１２３Ｂの第１延長部１２３ｂ－１を跨ぐように金属膜１２２Ｂに結合される。より詳細には、ＲＦＩＤモジュール１３０は、第１及び第２電極１３１，１３２がループアンテナパターン１２２ｈの第１端１２２ｈａ及び第２端１２２ｈｂにそれぞれ結合されるように、蓋１２０Ｂにある。第１及び第２電極１３１，１３２は、ループアンテナパターン１２２ｈの第１端１２２ｈａ及び第２端１２２ｈｂにそれぞれ容量結合される。 The RFID module 130 is coupled to the metal film 122B in the lid 120B so as to straddle the first extension 123b-1 of the slit 123B. More specifically, the RFID module 130 is on the lid 120B such that the first and second electrodes 131, 132 are respectively coupled to the first end 122ha and the second end 122hb of the loop antenna pattern 122h. The first and second electrodes 131, 132 are capacitively coupled to the first end 122ha and the second end 122hb of the loop antenna pattern 122h, respectively.
　図９の蓋１２０Ｂでは、金属膜１２２Ｂのループアンテナパターン１２２ｈは、ＲＦＩＤモジュール１３０に対して、ループアンテナとして機能する。 In the lid 120B of FIG. 9, the loop antenna pattern 122h of the metal film 122B functions as a loop antenna for the RFID module 130.
　以上述べた変形例２において、金属膜１２２Ｂは、アンテナパターン（ループアンテナパターン１２２ｈ）を含む。ＲＦＩＤモジュール１３０は、第１及び第２電極１３１，１３２がアンテナパターン（ループアンテナパターン１２２ｈ）に結合されるように、蓋１２０Ｂにある。この構成は、金属膜１２２Ｂがアンテナパターンを有するから、ＲＦＩＤモジュール１３０での無線通信の効率を向上できる。 In Modification 2 described above, the metal film 122B includes an antenna pattern (loop antenna pattern 122h). The RFID module 130 is on the lid 120B such that the first and second electrodes 131, 132 are coupled to the antenna pattern (loop antenna pattern 122h). This configuration can improve the efficiency of wireless communication in the RFID module 130 because the metal film 122B has an antenna pattern.
　変形例２において、アンテナパターンは、ループアンテナパターン１２２ｈを含む。ＲＦＩＤモジュール１３０は、第１及び第２電極１３１，１３２がループアンテナパターン１２２ｈの第１及び第２端１２２ｈａ，１２２ｈｂにそれぞれ結合されるように、蓋１２０Ｂにある。この構成は、ループアンテナを形成できる。 In Modification 2, the antenna pattern includes a loop antenna pattern 122h. The RFID module 130 is on the lid 120B such that the first and second electrodes 131, 132 are respectively coupled to the first and second ends 122ha, 122hb of the loop antenna pattern 122h. This configuration can form a loop antenna.
　変形例２において、ループアンテナパターン１２２ｈの形状は、金属膜１２２Ｂに形成されるスリット１２３Ｂにより規定される。スリット１２３Ｂは、金属膜１２２Ｂにおいて収容空間１１１の開口を覆う所定領域Ｒ１００を避けて配置される。この構成は、金属膜１２２Ｂによる内容物Ｎ１００の保護機能に影響を及ぼすことなく、ループアンテナパターン１２２ｈを設けることができる。 In Modification 2, the shape of the loop antenna pattern 122h is defined by the slit 123B formed in the metal film 122B. The slit 123B is arranged to avoid the predetermined region R100 covering the opening of the accommodation space 111 in the metal film 122B. This configuration allows provision of the loop antenna pattern 122h without affecting the protection function of the contents N100 by the metal film 122B.

　スリット１２３Ｃにより、金属膜１２２Ｃにおけるスリット１２３Ｃの周囲にループアンテナパターン１２２ｉが形成される。ループアンテナパターン１２２ｉは、スリット１２３Ｃを囲う形状であるが、スリット１２３Ｃの第１辺部１２３ｃにおいて分離されている。これによって、ループアンテナパターン１２２ｉは、第１辺部１２３ｃを挟んで対向する第１及び第２端１２２ｉａ，１２２ｉｂを有する。 The slit 123C forms a loop antenna pattern 122i around the slit 123C in the metal film 122C. The loop antenna pattern 122i has a shape surrounding the slit 123C, but is separated at the first side portion 123c of the slit 123C. Accordingly, the loop antenna pattern 122i has first and second ends 122ia and 122ib facing each other across the first side portion 123c.

More specifically, the RFID module 130 is on the lid 120C such that the first and second electrodes 131, 132 are respectively coupled to the first end 122ia and the second end 122ib of the loop antenna pattern 122i. Also in FIG. 10, the RFID module 130 is located at a portion facing the flange portion 113 on the lid 120C. The first and second electrodes 131, 132 are capacitively coupled to the first end 122ia and the second end 122ib of the loop antenna pattern 122i, respectively.

Hereinafter, the first portion 122k may be referred to as the first antenna pattern 122k, and the second portion 122l may be referred to as the second antenna pattern 122l.
　ＲＦＩＤモジュール１３０は、蓋１２０Ｅにおいて、スリット１２３Ｅを跨ぐように金属膜１２２Ｅに結合される。より詳細には、ＲＦＩＤモジュール１３０は、第１及び第２電極１３１，１３２が第１及び第２アンテナパターン１２２ｋ，１２２ｌにそれぞれ結合されるように、蓋１２０Ｅにある。図１２においても、ＲＦＩＤモジュール１３０は、蓋１２０Ｅにおいてフランジ部１１３と対向する部位にある。第１及び第２電極１３１，１３２は、第１及び第２アンテナパターン１２２ｋ，１２２ｌにそれぞれ容量結合される。 The RFID module 130 is coupled to the metal film 122E across the slit 123E in the lid 120E. More specifically, the RFID module 130 is on the lid 120E such that the first and second electrodes 131, 132 are respectively coupled to the first and second antenna patterns 122k, 122l. Also in FIG. 12, the RFID module 130 is located at a portion facing the flange portion 113 on the lid 120E. The first and second electrodes 131, 132 are capacitively coupled to the first and second antenna patterns 122k, 122l, respectively.
　図１２の蓋１２０Ｅでは、金属膜１２２Ｅの第１及び第２アンテナパターン１２２ｋ，１２２ｌは、ＲＦＩＤモジュール１３０に対して、ダイポールアンテナとして機能する。 In the lid 120E of FIG. 12, the first and second antenna patterns 122k, 122l of the metal film 122E function as dipole antennas for the RFID module 130.
　図１２の蓋１２０Ｅでは、スリット１２３Ｅが所定方向に沿って形成されている。特に、スリット１２３Ｅが所定方向に沿って一直線上に形成されている。そのため、複数の蓋１２０Ｅにスリット１２３Ｅをまとめて形成することが可能となる。次に、図１３～図１５を参照して蓋１２０Ｅの製造方法の一例について説明する。蓋１２０Ｅの製造方法の一例は、第１工程、第２工程、及び第３工程を含む。 A slit 123E is formed along a predetermined direction in the lid 120E of FIG. In particular, the slit 123E is formed on a straight line along a predetermined direction. Therefore, it is possible to collectively form the slits 123E in the plurality of lids 120E. Next, an example of a method for manufacturing the lid 120E will be described with reference to FIGS. 13 to 15. FIG. An example of a method for manufacturing the lid 120E includes first, second, and third steps.
　図１３は、蓋１２０Ｅの製造方法の一例の第１工程の説明図である。第１工程は、複数の蓋１２０Ｅを形成可能な大きさのシート１４０を用意する。図１３では、シート１４０は、１６枚の蓋１２０Ｅを形成可能な大きさである。より詳細には、シート１４０は、４×４のマトリクス状に並んだ蓋１２０Ｅの形成予定領域Ｒ１２０を含む。シート１４０は、蓋１２０Ｅの基材１２１の基礎となる基材層に、蓋１２０Ｅの金属膜１２２Ｅの基礎となる金属層を形成して構成される。シート１４０における形成予定領域Ｒ１２０以外の部位Ｒ１２１は、蓋１２０Ｅには使用されない部位である。 FIG. 13 is an explanatory diagram of the first step of one example of the method of manufacturing the lid 120E. A first step prepares a sheet 140 having a size capable of forming a plurality of lids 120E. In FIG. 13, sheet 140 is sized to form 16 lids 120E. More specifically, the sheet 140 includes formation planned regions R120 for the lids 120E arranged in a 4×4 matrix. The sheet 140 is configured by forming a metal layer, which is the base of the metal film 122E of the lid 120E, on a base layer, which is the base of the base 121 of the lid 120E. A portion R121 of the sheet 140 other than the formation scheduled region R120 is a portion not used for the lid 120E.
　図１４は、蓋１２０Ｅの製造方法の一例の第２工程の説明図である。第２工程は、第１工程で用意したシート１４０の金属層に溝１５０を形成する。溝１５０において各形成予定領域Ｒ１２０に対応する部分がスリット１２３Ｅとなる。図１４では、所定方向に並ぶ複数（図１４では４つ）の形成予定領域Ｒ１２０に、所定方向に沿った１つの溝１５０が形成される。これによって、複数（図１４では４つ）のスリット１２３Ｅがまとめて形成される。 FIG. 14 is an explanatory diagram of the second step of one example of the method of manufacturing the lid 120E. The second step is to form the grooves 150 in the metal layer of the sheet 140 prepared in the first step. Portions of the grooves 150 corresponding to the respective formation-scheduled regions R120 serve as slits 123E. In FIG. 14, one groove 150 is formed along a predetermined direction in a plurality of (four in FIG. 14) formation scheduled regions R120 aligned in a predetermined direction. As a result, a plurality of (four in FIG. 14) slits 123E are collectively formed.
　図１５は、蓋１２０Ｅの製造方法の一例の第３工程の説明図である。第３工程は、複数の蓋１２０Ｅの形成予定領域Ｒ１２０に複数のＲＦＩＤモジュール１３０をそれぞれ配置する。 FIG. 15 is an explanatory diagram of the third step of one example of the method of manufacturing the lid 120E. In the third step, a plurality of RFID modules 130 are arranged in respective formation-planned regions R120 of a plurality of lids 120E.
　第３工程の後、シート１４０は切断されて、複数の蓋１２０Ｅに分離される。シート１４０の切断は、シート１４０を複数の本体１１０にまとめて貼り付けた後に実行されてよい。 After the third step, the sheet 140 is cut and separated into a plurality of lids 120E. The cutting of the sheet 140 may be performed after the sheet 140 is collectively attached to the plurality of bodies 110 .
　以上述べた変形例５では、スリット１２３Ｅは、金属膜１２２Ｅにおける収容空間１１１の開口の縁部に対応する部位に所定方向に沿って形成されて第１及び第２アンテナパターン１２２ｋ，１２２ｌ間を電気的に分離する。この構成は、複数の蓋１２０Ｅへのスリット１２３Ｅの形成をまとめて行うことを可能にする。 In Modified Example 5 described above, the slit 123E is formed along a predetermined direction in a portion of the metal film 122E corresponding to the edge of the opening of the accommodation space 111 to electrically connect the first and second antenna patterns 122k and 122l. physically separated. This configuration makes it possible to collectively form the slits 123E in a plurality of lids 120E.

　図１６の蓋２２０は、本体２１０に、複数の収容空間２１１の開口を覆うように取り付けられる。図１６の蓋２２０は、剥離可能に本体２１０に取り付けられる。蓋２２０は、本体２１０の収容空間２１１から内容物Ｎ１００を取り出す際に、本体２１０から剥離される。蓋２２０は全体的に可撓性を有する。 A lid 220 in FIG. 16 is attached to the main body 210 so as to cover the openings of the plurality of accommodation spaces 211 . Lid 220 in FIG. 16 is releasably attached to body 210 . The lid 220 is peeled off from the main body 210 when the content N100 is taken out from the housing space 211 of the main body 210 . Lid 220 is generally flexible.
　図１６の蓋２２０は、複数（図１６では４つ）の小蓋部２２５ａ～２２５ｄを有する。複数の小蓋部２２５ａ～２２５ｄは、本体２１０の複数の小本体部２１５ａ～２１５ｄにそれぞれ対応する。ＲＦＩＤ機能付き容器２００では、小本体部２１５ａ～２１５ｄと、小本体部２１５ａ～２１５ｄに対応する小蓋部２２５ａ～２２５ｄとが、小容器を構成する。蓋２２０は、基材２２１と、金属膜２２２とを含む。基材２２１は、複数の小本体部２１５ａ～２１５ｄの収容空間２１１の開口を覆う。特に、基材２２１は、複数の小本体部２１５ａ～２１５ｄの収容空間２１１の開口及びフランジ部２１３を全体的に覆う。基材２２１の外形形状は、正方形状である。基材２２１は、例えば、紙又はプラスチック等の誘電体材料から形成される。金属膜２２２は、複数の小本体部２１５ａ～２１５ｄの収容空間２１１の開口を包括的に覆う。金属膜２２２は、複数の小本体部２１５ａ～２１５ｄの収容空間２１１の開口及びフランジ部２１３を包括的に覆う。金属膜２２２は、基材２２１における本体２１０側の面にある。金属膜２２２は、外部要因に起因する内容物の変化を防止する作用を有し得る。このように、金属膜２２２は、小本体部２１５の収容空間２１１の開口を覆うことで、内容物Ｎ１００を保護する。金属膜２２２の材料としては、アルミニウム及びアルミニウムを含む合金が挙げられる。 The lid 220 in FIG. 16 has a plurality of (four in FIG. 16) small lid portions 225a to 225d. The plurality of small lid portions 225a-225d correspond to the plurality of small main body portions 215a-215d of the main body 210, respectively. In the RFID function-equipped container 200, small main bodies 215a to 215d and small lids 225a to 225d corresponding to the small main bodies 215a to 215d constitute a small container. Lid 220 includes base material 221 and metal film 222 . The base material 221 covers the openings of the housing spaces 211 of the plurality of small main bodies 215a to 215d. In particular, the base material 221 entirely covers the openings of the accommodating spaces 211 and the flange portions 213 of the plurality of small body portions 215a to 215d. The outer shape of the base material 221 is square. Substrate 221 is formed from, for example, a dielectric material such as paper or plastic. The metal film 222 comprehensively covers the openings of the housing spaces 211 of the plurality of small main bodies 215a to 215d. The metal film 222 comprehensively covers the openings of the accommodating spaces 211 and the flange portions 213 of the plurality of small main body portions 215a to 215d. The metal film 222 is on the surface of the base material 221 on the main body 210 side. The metal film 222 can act to prevent changes in the contents due to external factors. Thus, the metal film 222 protects the content N100 by covering the opening of the accommodation space 211 of the small body portion 215. As shown in FIG. Materials for the metal film 222 include aluminum and alloys containing aluminum.
　４つの小蓋部２２５ａ～２２５ｄは、２×２のマトリクス状に配置されている。蓋２２０の中央には、４つの小蓋部２２５ａ～２２５ｄで囲まれた開口２２６がある。開口２２６は、蓋２２０において、本体２１０の所定の部位（中央部）に対応する位置にある。４つの小蓋部２２５ａ～２２５ｄは、互いに連結されている。蓋２２０において隣接する小蓋部２２５ａ，２２５ｂ間には、ミシン目２２４ａが形成される。ミシン目２２４ａは、小蓋部２２５ａ，２２５ｂ同士を分離するために用いられる。蓋２２０において隣接する小蓋部２２５ａ，２２５ｃ間には、ミシン目２２４ｂが形成される。ミシン目２２４ｂは、小蓋部２２５ａ，２２５ｃ同士を分離するために用いられる。蓋２２０において隣接する小蓋部２２５ｃ，２２５ｄ間には、ミシン目２２４ｃが形成される。ミシン目２２４ｃは、小蓋部２２５ｃ，２２５ｄ同士を分離するために用いられる。蓋２２０において隣接する小蓋部２２５ｂ，２２５ｄ間には、ミシン目２２４ｄが形成される。ミシン目２２４ｄは、小蓋部２２５ｂ，２２５ｄ同士を分離するために用いられる。ミシン目２２４ａ～２２４ｄは、蓋２２０において本体２１０のミシン目２１４ａ～２１４ｄと重なる位置に形成される。よって、ミシン目２２４ａ～２２４ｄの各々は、本体２１０において一対の収容空間２１１の間に、一対の収容空間２１１が隣接する方向に交差する方向に並ぶ複数のスリットで構成される。蓋２２０のミシン目（第２ミシン目）２２４ａ～２２４ｄによって小蓋部２２５ａ～２２５ｄ同士を切り離すことが可能である。 The four small lid portions 225a to 225d are arranged in a 2×2 matrix. At the center of the lid 220 is an opening 226 surrounded by four small lid portions 225a-225d. The opening 226 is located in the lid 220 at a position corresponding to a predetermined portion (central portion) of the main body 210 . The four small lid portions 225a-225d are connected to each other. A perforation 224a is formed between the adjacent small lid portions 225a and 225b in the lid 220. As shown in FIG. The perforations 224a are used to separate the small lid portions 225a and 225b from each other. A perforation 224b is formed between the adjacent small lid portions 225a and 225c in the lid 220. As shown in FIG. The perforations 224b are used to separate the small lid portions 225a and 225c from each other. A perforation 224c is formed between the adjacent small lid portions 225c and 225d in the lid 220. As shown in FIG. The perforations 224c are used to separate the small lid portions 225c and 225d. A perforation 224d is formed between the adjacent small lid portions 225b and 225d in the lid 220. As shown in FIG. The perforations 224d are used to separate the small lid portions 225b and 225d. The perforations 224a-224d are formed on the lid 220 at positions overlapping the perforations 214a-214d of the main body 210. As shown in FIG. Therefore, each of the perforations 224a to 224d is composed of a plurality of slits arranged between the pair of storage spaces 211 in the main body 210 in a direction intersecting the direction in which the pair of storage spaces 211 are adjacent to each other. Perforations (second perforations) 224a to 224d of the lid 220 allow the small lid portions 225a to 225d to be separated from each other.
　蓋２２０は、接着剤により小蓋部２２５ａ～２２５ｄを小本体部２１５ａ～２１５ｄの収容空間２１１の開口の周縁部分に取り付けることで、本体２１０に取り付けられる。図１６では、小蓋部２２５ａ～２２５ｄは、小本体部２１５ａ～２１５ｄのフランジ部２１３に接着剤で取り付けられる。接着剤は、小蓋部２２５ａ～２２５ｄにおいてフランジ部２１３に対向する領域に塗布される。つまり、ミシン目２１４ａ～２１４ｄ，２２４ａ～２２４ｄによって、ＲＦＩＤ機能付き容器２００を、小本体部２１５ａ～２１５ｄと小蓋部２２５ａ～２２５ｄとで構成される小容器に分離した際にも、各小容器では小蓋部２２５ａ～２２５ｄが小本体部２１５ａ～２１５ｄに接着剤で取り付けられた状態となっている。 The lid 220 is attached to the main body 210 by attaching the small lid portions 225a to 225d to the periphery of the opening of the housing space 211 of the small main body portions 215a to 215d with an adhesive. In FIG. 16, the small lid portions 225a-225d are adhesively attached to the flange portions 213 of the small body portions 215a-215d. The adhesive is applied to the areas facing the flange portion 213 in the small lid portions 225a to 225d. That is, even when the RFID function-equipped container 200 is separated into small containers composed of the small main body portions 215a to 215d and the small lid portions 225a to 225d by the perforations 214a to 214d and 224a to 224d, each small container 2, the small lid portions 225a to 225d are attached to the small main body portions 215a to 215d with an adhesive.
　図１７は、蓋２２０の底面図である。図１７に示すように、金属膜２２２は、蓋２２０における本体２１０側の全面にあって、本体２１０の封数の収容空間２１１を包括的に覆う。蓋２２０には中央に開口２２６があるため、開口２２６に対応する部位には金属膜２２２が存在しない。金属膜２２２には、スリット２２３が形成される。図１７のスリット２２３は、金属膜２２２において本体２１０の収容空間２１１の開口を覆う所定領域Ｒ２００を避けて配置される。図１７のスリット２２３は、金属膜２２２において本体２１０の小本体部２１５ａのフランジ部２１３に対向する角部に形成されている。スリット２２３は、開口２２６から反対側の角部に向かって延びている。 17 is a bottom view of the lid 220. FIG. As shown in FIG. 17, the metal film 222 is on the entire surface of the lid 220 on the main body 210 side and comprehensively covers the housing space 211 of the main body 210 . Since the lid 220 has an opening 226 in the center, the metal film 222 does not exist in the area corresponding to the opening 226 . A slit 223 is formed in the metal film 222 . The slit 223 in FIG. 17 is arranged in the metal film 222 so as to avoid the predetermined region R200 that covers the opening of the housing space 211 of the main body 210 . A slit 223 in FIG. 17 is formed at a corner of the metal film 222 facing the flange portion 213 of the small main body portion 215a of the main body 210 . Slit 223 extends from opening 226 toward the opposite corner.
　スリット２２３により、金属膜２２２における開口２２６の周囲にループアンテナパターン２２２ａが形成される。ループアンテナパターン２２２ａによって、図１７において両矢印Ａで示すように電流が流れる経路が発生し得る。ループアンテナパターン２２２ａは、開口２２６を囲う形状であるが、スリット２２３において部分的に分離されている。これによって、ループアンテナパターン２２２ａは、スリット２２３を挟んで対向する第１及び第２端２２２ａａ，２２２ａｂを有する。 A loop antenna pattern 222 a is formed around the opening 226 in the metal film 222 by the slit 223 . The loop antenna pattern 222a can generate a path through which current flows as indicated by a double-headed arrow A in FIG. Loop antenna pattern 222 a has a shape surrounding opening 226 , but is partially separated at slit 223 . Accordingly, the loop antenna pattern 222a has first and second ends 222aa and 222ab facing each other with the slit 223 therebetween.
　ＲＦＩＤモジュール２３０は、ＲＦＩＤ１３０と同じである。ＲＦＩＤモジュール２３０は、蓋２２０において、スリット２２３を跨ぐように金属膜２２２に結合される。より詳細には、ＲＦＩＤモジュール２３０は、第１及び第２電極２３１，２３２がループアンテナパターン２２２ａの第１端２２２ａａ及び第２端２２２ａｂにそれぞれ結合されるように、蓋２２０にある。図１７においても、ＲＦＩＤモジュール２３０は、蓋２２０においてフランジ部２１３と対向する部位にある。第１及び第２電極２３１，２３２は、ループアンテナパターン２２２ａの第１端２２２ａａ及び第２端２２２ａｂにそれぞれ容量結合される。 The RFID module 230 is the same as the RFID 130. RFID module 230 is coupled to metal film 222 across slit 223 in lid 220 . More specifically, the RFID module 230 is on the lid 220 such that the first and second electrodes 231, 232 are respectively coupled to the first end 222aa and the second end 222ab of the loop antenna pattern 222a. In FIG. 17 as well, the RFID module 230 is located at a portion of the lid 220 facing the flange portion 213 . The first and second electrodes 231, 232 are capacitively coupled to the first end 222aa and the second end 222ab of the loop antenna pattern 222a, respectively.
　図１７のＲＦＩＤ機能付き容器２００では、ＲＦＩＤ機能付き容器２００が小容器に分離される前は、金属膜２２２のループアンテナパターン２２２ａが、ＲＦＩＤモジュール２３０に対して、ループアンテナとして機能する。つまり、複数の収容空間２１１が個別に分離される前は、ＲＦＩＤモジュール２３０は金属膜２２２を利用して通信可能である。一方で、ＲＦＩＤ機能付き容器２００が小容器に分離されると、金属膜２２２がミシン目２２４で分離されることでループアンテナパターン２２２ａが破損するから、ループアンテナパターン２２２ａは、ＲＦＩＤモジュール２３０に対して、ループアンテナとして機能しなくなる。そのため、ＲＦＩＤ機能付き容器２００が小容器に分離された後には、ＲＦＩＤ機能が機能しなくなる。つまり、複数の収容空間２１１が個別に分離された後は、ＲＦＩＤモジュール２３０は金属膜２２２を利用して通信できなくなる。 In the RFID function-equipped container 200 of FIG. 17, the loop antenna pattern 222a of the metal film 222 functions as a loop antenna for the RFID module 230 before the RFID function-equipped container 200 is separated into small containers. In other words, the RFID modules 230 can communicate using the metal films 222 before the plurality of accommodation spaces 211 are individually separated. On the other hand, when the RFID function-equipped container 200 is separated into small containers, the metal film 222 is separated at the perforations 224 and the loop antenna pattern 222a is damaged. and will not function as a loop antenna. Therefore, after the RFID function-equipped container 200 is separated into small containers, the RFID function ceases to function. In other words, after the plurality of accommodation spaces 211 are individually separated, the RFID module 230 cannot communicate using the metal film 222 .

On the other hand, after the plurality of accommodation spaces 211 are individually separated, the RFID module 230 cannot communicate using the metal film 222 .
　［１．２．３　変形例］
　実施の形態２は、上記構成に限定されない。実施の形態２は、その課題を達成できれば、設計等に応じて種々の変更が可能である。次に、実施の形態２の一変形例のＲＦＩＤ機能付き容器について説明する。本変形例は、図１８に示す蓋２２０Ａを備える点で、実施の形態２のＲＦＩＤ機能付き容器２００と異なる。図１８は、実施の形態２の一変形例のＲＦＩＤ機能付き容器の蓋２２０Ａの構成例の底面図である。 [1.2.3 Modification]
Embodiment 2 is not limited to the above configuration. Embodiment 2 can be modified in various ways according to the design, etc., as long as the problem can be achieved. Next, a container with an RFID function, which is a modified example of the second embodiment, will be described. This modification differs from the RFID function-equipped container 200 of the second embodiment in that a lid 220A shown in FIG. 18 is provided. FIG. 18 is a bottom view of a configuration example of a lid 220A of a container with an RFID function according to one modification of the second embodiment.
　図１８の蓋２２０Ａは、本体２１０に、複数の収容空間２１１の開口を覆うように取り付けられる。図１８の蓋２２０Ａは、剥離可能に本体２１０に取り付けられる。蓋２２０Ａは、本体２１０の収容空間２１１から内容物Ｎ１００を取り出す際に、本体２１０から剥離される。蓋２２０Ａは全体的に可撓性を有する。 The lid 220A in FIG. 18 is attached to the main body 210 so as to cover the openings of the plurality of accommodation spaces 211. Lid 220A in FIG. 18 is releasably attached to main body 210 . The lid 220A is peeled off from the main body 210 when the content N100 is taken out from the housing space 211 of the main body 210. As shown in FIG. Lid 220A is generally flexible.
　図１７の蓋２２０Ａは、基材２２１Ａと、金属膜２２２Ａとを含む。金属膜２２２Ａは、蓋２２０における本体２１０側の全面にあって、本体２１０の封数の収容空間２１１を包括的に覆う。図１７の蓋２２０Ａは、図１６の蓋２２０と同様に、複数の小蓋部２２５ａ～２２５ｄを有する。４つの小蓋部２２５ａ～２２５ｄは、２×２のマトリクス状に配置されている。上述したように、蓋２２０Ａにおいて、隣接する小蓋部２２５ａ，２２５ｂ間、隣接する小蓋部２２５ａ，２２５ｃ間、隣接する小蓋部２２５ｃ，２２５ｄ間、及び、隣接する小蓋部２２５ｂ，２２５ｄ間には、それぞれ、ミシン目２２４ａ～２２４ｄが形成される。ミシン目２２４ａ～２２４ｄの各々は、複数のスリットで構成される。複数のスリットの大きさ及び複数のスリットの間隔を適宜設定することで、ミシン目２２４ａ～２２４ｄの各々は、隣接する小蓋部間を実質的に電気的に分離するように構成されている。 A lid 220A in FIG. 17 includes a base material 221A and a metal film 222A. The metal film 222A is on the entire surface of the lid 220 on the main body 210 side and comprehensively covers the housing space 211 of the main body 210 . Lid 220A in FIG. 17 has a plurality of small lid portions 225a to 225d, like lid 220 in FIG. The four small lid portions 225a to 225d are arranged in a 2×2 matrix. As described above, in the lid 220A, between the adjacent small lid portions 225a and 225b, between the adjacent small lid portions 225a and 225c, between the adjacent small lid portions 225c and 225d, and between the adjacent small lid portions 225b and 225d. are formed with perforations 224a to 224d, respectively. Each of the perforations 224a-224d is composed of a plurality of slits. By appropriately setting the size of the plurality of slits and the spacing of the plurality of slits, each of the perforations 224a to 224d is configured to substantially electrically isolate adjacent small lid portions.
　ミシン目２２４ａにより、金属膜２２２Ａにおける小蓋部２２５ａ，２２５ｂにそれぞれ対応する部位を電気的に分離されたアンテナパターンとして利用できる。ミシン目２２４ｂにより、金属膜２２２Ａにおける小蓋部２２５ａ，２２５ｃにそれぞれ対応する部位を電気的に分離されたアンテナパターンとして利用できる。ミシン目２２４ｃにより、金属膜２２２Ａにおける小蓋部２２５ｃ，２２５ｄにそれぞれ対応する部位を電気的に分離されたアンテナパターンとして利用できる。ミシン目２２４ｄにより、金属膜２２２Ａにおける小蓋部２２５ｂ，２２５ｄにそれぞれ対応する部位を電気的に分離されたアンテナパターンとして利用できる。 Due to the perforations 224a, the portions of the metal film 222A corresponding to the small lid portions 225a and 225b can be used as electrically separated antenna patterns. Due to the perforations 224b, portions of the metal film 222A corresponding to the small lid portions 225a and 225c can be used as electrically separated antenna patterns. Due to the perforations 224c, portions of the metal film 222A corresponding to the small lid portions 225c and 225d can be used as electrically separated antenna patterns. Due to the perforations 224d, portions of the metal film 222A corresponding to the small lid portions 225b and 225d can be used as electrically separated antenna patterns.
　図１８に示すように、ＲＦＩＤモジュール２３０は、蓋２２０Ａにおける所定領域Ｒ２００の外側にあって金属膜２２２Ａに結合される。ＲＦＩＤモジュール２３０は、蓋２２０Ａにおいて本体２１０のフランジ部２１３と対向する部位にある。ＲＦＩＤモジュール２３０は、蓋２２０Ａにおいて、ミシン目２２４ｂを跨ぐように金属膜２２２Ａに結合される。より詳細には、ＲＦＩＤモジュール２３０は、第１及び第２電極２３１，２３２が金属膜２２２Ａにおける小蓋部２２５ａ，２２５ｃにそれぞれ対応する部位にそれぞれ結合されるように、蓋２２０Ａにある。この場合、金属膜２２２Ａにおける小蓋部２２５ａ，２２５ｃにそれぞれ対応する部位が第１及び第２アンテナパターンとして機能する。第１及び第２電極２３１，２３２は、第１及び第２アンテナパターンにそれぞれ容量結合される。 As shown in FIG. 18, the RFID module 230 is outside the predetermined region R200 on the lid 220A and is coupled to the metal film 222A. The RFID module 230 is located at a portion of the lid 220A facing the flange portion 213 of the main body 210 . RFID module 230 is coupled to metal membrane 222A across perforations 224b in lid 220A. More specifically, the RFID module 230 is located on the lid 220A such that the first and second electrodes 231, 232 are coupled to portions of the metal film 222A corresponding to the small lid portions 225a, 225c, respectively. In this case, portions of the metal film 222A corresponding to the small lid portions 225a and 225c function as first and second antenna patterns. The first and second electrodes 231, 232 are capacitively coupled to the first and second antenna patterns, respectively.
　本変形例では、ＲＦＩＤ機能付き容器が小容器に分離される前は、金属膜２２２Ａの第１及び第２アンテナパターンが、ＲＦＩＤモジュール２３０に対して、ダイポールアンテナとして機能する。つまり、複数の収容空間２１１が個別に分離される前は、ＲＦＩＤモジュール２３０は金属膜２２２Ａを利用して通信可能である。一方で、ＲＦＩＤ機能付き容器が小容器に分離されると、金属膜２２２Ａがミシン目２２４で分離されることで第１及び第２アンテナパターンの少なくとも一方とＲＦＩＤモジュール２３０との結合が維持できなくなる。場合によっては、ＲＦＩＤモジュール２３０が蓋２２０Ａから脱落する。これにより、金属膜２２２Ａは、ＲＦＩＤモジュール２３０に対して、ダイポールアンテナとして機能しなくなる。そのため、ＲＦＩＤ機能付き容器が小容器に分離された後には、ＲＦＩＤ機能が機能しなくなる。つまり、複数の収容空間２１１が個別に分離された後は、ＲＦＩＤモジュール２３０は金属膜２２２Ａを利用して通信できなくなる。 In this modified example, the first and second antenna patterns of the metal film 222A function as dipole antennas for the RFID module 230 before the container with RFID function is separated into small containers. In other words, the RFID module 230 can communicate using the metal film 222A before the plurality of accommodation spaces 211 are individually separated. On the other hand, when the RFID function-equipped container is separated into small containers, the metal film 222A is separated by the perforations 224, so that at least one of the first and second antenna patterns and the RFID module 230 cannot maintain their connection. . In some cases, RFID module 230 falls off lid 220A. As a result, the metal film 222A no longer functions as a dipole antenna for the RFID module 230. FIG. Therefore, after the RFID function-equipped container is separated into small containers, the RFID function ceases to function. In other words, after the plurality of housing spaces 211 are individually separated, the RFID module 230 cannot communicate using the metal film 222A.
　以上述べた変形例において、本体２１０は、それぞれ収容空間２１１を有する一対の小本体部２１５ａ，２１５ｂと、一対の小本体部２１５ａ，２１５ｂ同士を分離するための第１ミシン目２１４ａとを有する。蓋２２０は、一対の小本体部２１５ａ，２１５ｂにそれぞれ対応する一対の小蓋部２２５ａ，２２５ｂと、一対の小蓋部２２５ａ，２２５ｂ同士を分離するための第２ミシン目２２４ａとを有する。第２ミシン目２２４ａは、金属膜２２２において一対の小蓋部２２５ａ，２２５ｂに対応する部分同士を電気的に分離する。ＲＦＩＤモジュール２３０は、第２ミシン目２２４ａを跨ぐように蓋２２０Ａにある。この構成は、各々内容物Ｎ１００を収容する複数の収容空間２１１を有する本体２１０に金属膜２２２Ａを有する蓋２２０Ａが取り付けられる容器において、意匠性の低減を抑制しつつもＲＦＩＤモジュール２３０が内容物Ｎ１００に混入する可能性を低減できる。また、複数の収容空間２１１が個別に分離される前は、ＲＦＩＤモジュール２３０は金属膜２２２Ａを利用して通信可能である。一方で、複数の収容空間２１１が個別に分離された後は、ＲＦＩＤモジュール２３０は金属膜２２２Ａを利用して通信できなくなる。 In the modified example described above, the main body 210 has a pair of small main body portions 215a and 215b each having an accommodation space 211, and a first perforation 214a for separating the pair of small main body portions 215a and 215b. The lid 220 has a pair of small lid portions 225a and 225b respectively corresponding to the pair of small main body portions 215a and 215b, and a second perforation 224a for separating the pair of small lid portions 225a and 225b. The second perforations 224a electrically separate portions of the metal film 222 corresponding to the pair of small lid portions 225a and 225b. RFID module 230 is on lid 220A across second perforation 224a. With this configuration, in a container in which a lid 220A having a metal film 222A is attached to a main body 210 having a plurality of housing spaces 211 each housing a content N100, the RFID module 230 can be used to store the content N100 while suppressing deterioration in design. can reduce the possibility of contamination with Also, before the plurality of accommodation spaces 211 are individually separated, the RFID module 230 can communicate using the metal film 222A. On the other hand, after the plurality of accommodation spaces 211 are individually separated, the RFID module 230 cannot communicate using the metal film 222A.

The lid 320 is attached to the periphery of the opening of the accommodation space 311 of the main body 310 with an adhesive. The adhesive is applied to an annular region R310 of the main portion 320a of the lid 320 facing the periphery of the opening of the housing space 311. As shown in FIG.
　蓋３２０は、基材３２１と、金属膜３２２とを含む。基材３２１は、収容空間３１１の開口を覆う。特に、基材３２１は、収容空間３１１の開口及び収容空間３１１の開口の周縁部分を全体的に覆う。基材３２１の外形形状は、蓋３２０の外形形状を規定する。基材３２１は、例えば、紙又はプラスチック等の誘電体材料から形成される。金属膜３２２は、本体３１０の収容空間３１１の開口を覆う。金属膜３２２は、収容空間３１１の開口及び収容空間３１１の開口の周縁部分を全体的に覆う。金属膜３２２は、基材３２１における本体３１０側の面にある。金属膜３２２は、外部要因に起因する内容物の変化を防止する作用を有し得る。このように、金属膜３２２は、収容空間３１１の開口を覆うことで、内容物Ｎ１００を保護する。金属膜３２２の材料としては、アルミニウム及びアルミニウムを含む合金が挙げられる。 The lid 320 includes a base material 321 and a metal film 322. The base material 321 covers the opening of the accommodation space 311 . In particular, the base material 321 entirely covers the opening of the accommodation space 311 and the peripheral portion of the opening of the accommodation space 311 .

The metal film 322 entirely covers the opening of the accommodation space 311 and the periphery of the opening of the accommodation space 311 . The metal film 322 is on the surface of the base material 321 on the main body 310 side. The metal film 322 can act to prevent changes in the contents due to external factors. Thus, the metal film 322 protects the content N100 by covering the opening of the accommodation space 311. FIG. Materials for the metal film 322 include aluminum and alloys containing aluminum.
　図２０は、蓋３２０の底面図である。図２０に示すように、金属膜３２２は、複数の部位に分割される。より詳細には、金属膜３２２は、金属膜３２２の外縁部に対応する第１及び第２辺部３２２ａ，３２２ｂと、収容空間３１１の開口を覆う中央部３２２ｃとに分割される。中央部３２２ｃは、金属膜３２２において収容空間３１１の開口を覆う所定領域Ｒ３００を含む。第１辺部３２２ａは、蓋３２０の主部３２０ａにある第１部位３２２ａ１と、蓋３２０の持ち手部３２０ｂにある第２部位３２２ａ２とを含む。第２辺部３２２ｂは、蓋３２０の主部３２０ａにある第１部位３２２ｂ１と、蓋３２０の持ち手部３２０ｂにある第２部位３２２ｂ２とを含む。金属膜３２２において、第１及び第２辺部３２２ａ，３２２ｂと中央部３２２ｃとは互いに電気的に分離されている。第１及び第２辺部３２２ａ，３２２ｂは、ＲＦＩＤモジュール３３０のためのアンテナパターンとして用いることができる。図２０では、第１及び第２辺部３２２ａ，３２２ｂが、互いに電気的に独立した第１及び第２アンテナパターンを構成する。本実施の形態では、第１辺部３２２ａを第１アンテナパターン３２２ａといい、第２辺部３２２ｂを第２アンテナパターン３２２ｂということがある。 20 is a bottom view of the lid 320. FIG. As shown in FIG. 20, the metal film 322 is divided into multiple parts. More specifically, the metal film 322 is divided into first and second side portions 322 a and 322 b corresponding to the outer edges of the metal film 322 and a central portion 322 c covering the opening of the accommodation space 311 . The center portion 322c includes a predetermined region R300 that covers the opening of the accommodation space 311 in the metal film 322. As shown in FIG. The first side portion 322 a includes a first portion 322 a 1 on the main portion 320 a of the lid 320 and a second portion 322 a 2 on the handle portion 320 b of the lid 320 . The second side portion 322 b includes a first portion 322 b 1 on the main portion 320 a of the lid 320 and a second portion 322 b 2 on the handle portion 320 b of the lid 320 . In the metal film 322, the first and second side portions 322a, 322b and the central portion 322c are electrically isolated from each other. The first and second sides 322 a , 322 b can be used as antenna patterns for the RFID module 330 . In FIG. 20, the first and second sides 322a and 322b form first and second antenna patterns that are electrically independent of each other. In this embodiment, the first side portion 322a may be referred to as the first antenna pattern 322a, and the second side portion 322b may be referred to as the second antenna pattern 322b.
　金属膜３２２は、金属膜３２２に形成されるスリット３２３により、第１及び第２辺部３２２ａ，３２２ｂと収容空間３１１の開口を覆う中央部３２２ｃとに分割される。したがって、第１及び第２アンテナパターン３２２ａ，３２２ｂの形状は、金属膜３２２に形成されるスリット３２３により規定される。スリット３２３は、金属膜３２２において本体３１０の収容空間３１１の開口を覆う所定領域Ｒ３００を避けて配置される。これにより、金属膜３２２による内容物Ｎ１００の保護機能に影響を及ぼすことなく、アンテナパターン３２２ａ，３２２ｂを設けることができる。図２０のスリット３２３は、第１延長部３２３ａと、枠部３２３ｂと、第２延長部３２３ｃとを含む。枠部３２３ｂは、所定領域Ｒ１００を囲う円環状である。枠部３２３ｂの外形形状は蓋３２０の主部３２０ａと同心円である。第１及び第２延長部３２３ａ，３２３ｃの各々は、枠部３２３ｂから蓋３２０の外方に延びている。特に、第１延長部３２３ａは、蓋３２０の持ち手部３２０ｂを２分するように、枠部３２３ｂから延びている。第２延長部３２３ｃは、枠部３２３ｂから第１延長部３２３ａとは反対方向に延びている。第１及び第２延長部３２３ａ，３２３ｃは一直線上に並ぶ。スリット３２３において、枠部３２３ｂは、収容空間３１１の開口を囲うように形成されて所定領域Ｒ３００から第１及び第２アンテナパターン３２２ａ，３２２ｂを電気的に分離する第１部位である。第１及び第２延長部３２３ａ，３２３ｃは、収容空間３１１の開口の縁部に形成されて第１及び第２アンテナパターン３２２ａ，３２２ｂ間を電気的に分離する第２部位である。なお、スリット３２３は、金属膜３２２を貫通するが基材３２１を貫通しない。 A slit 323 formed in the metal film 322 divides the metal film 322 into first and second side portions 322 a and 322 b and a central portion 322 c covering the opening of the accommodation space 311 . Therefore, the shapes of the first and second antenna patterns 322 a and 322 b are defined by the slits 323 formed in the metal film 322 . The slit 323 is arranged in the metal film 322 so as to avoid the predetermined region R300 covering the opening of the accommodation space 311 of the main body 310 . Accordingly, the antenna patterns 322a and 322b can be provided without affecting the function of the metal film 322 to protect the contents N100. The slit 323 of FIG. 20 includes a first extension portion 323a, a frame portion 323b, and a second extension portion 323c. The frame portion 323b has an annular shape surrounding the predetermined region R100. The outer shape of the frame portion 323b is concentric with the main portion 320a of the lid 320. As shown in FIG. Each of the first and second extensions 323a and 323c extends outward from the lid 320 from the frame 323b. In particular, the first extension portion 323a extends from the frame portion 323b so as to divide the handle portion 320b of the lid 320 into two parts. The second extension portion 323c extends from the frame portion 323b in the opposite direction to the first extension portion 323a. The first and second extensions 323a, 323c are aligned. In the slit 323, the frame portion 323b is a first portion formed to surround the opening of the accommodation space 311 and electrically separate the first and second antenna patterns 322a and 322b from the predetermined region R300. The first and second extensions 323a and 323c are second parts formed at the edge of the opening of the receiving space 311 to electrically separate the first and second antenna patterns 322a and 322b. Note that the slit 323 penetrates the metal film 322 but does not penetrate the base material 321 .
　図２０に示すように、ＲＦＩＤモジュール３３０は、蓋３２０における所定領域Ｒ３００の外側にあって金属膜１２２に結合される。つまり、ＲＦＩＤモジュール３３０は、蓋３２０における収容空間３１１の開口の外側にあって金属膜３２２に結合される。ＲＦＩＤモジュール３３０は、蓋３２０の持ち手部３２０ｂにある。ＲＦＩＤ機能付き容器３００の輸送時又は陳列時等においてＲＦＩＤ機能付き容器３００を重ねた場合、本体３１０が重なる。ＲＦＩＤ機能付き容器３００では、上述したように、ＲＦＩＤモジュール３３０は、蓋３２０の持ち手部３２０ｂにある。そのため、ＲＦＩＤモジュール３３０は、ＲＦＩＤモジュール３３０が蓋３２０の主部３２０ａにある場合に比べて、別のＲＦＩＤ機能付き容器３００からの影響、特に、内容物Ｎ１００からの影響を受けにくい。そのため、本実施の形態のＲＦＩＤ機能付き容器３００は、ＲＦＩＤ機能付き容器３００を重ねた場合、本体３１０が重なるので、ＲＦＩＤモジュール３３０の機能を損ねる可能性を低減できる。 As shown in FIG. 20, the RFID module 330 is outside the predetermined region R300 on the lid 320 and is coupled to the metal film 122. As shown in FIG. That is, the RFID module 330 is outside the opening of the housing space 311 in the lid 320 and coupled to the metal film 322 . The RFID module 330 is located in the handle portion 320b of the lid 320. FIG. When the RFID function-equipped containers 300 are piled up during transportation or display of the RFID function-equipped containers 300, the main bodies 310 overlap each other. In the RFID function-equipped container 300, the RFID module 330 is located on the handle portion 320b of the lid 320, as described above. Therefore, the RFID module 330 is less likely to be affected by another RFID-equipped container 300, particularly by the contents N100, than when the RFID module 330 is in the main portion 320a of the lid 320. FIG. Therefore, when the RFID function-equipped container 300 of the present embodiment is stacked, the main body 310 overlaps with the RFID function-equipped container 300 , which reduces the possibility of impairing the function of the RFID module 330 .
　ＲＦＩＤモジュール３３０は、蓋３２０の持ち手部３２０ｂにおいて、スリット３２３の第１延長部３２３ａを跨ぐように金属膜３２２に結合される。より詳細には、ＲＦＩＤモジュール３３０は、第１及び第２電極３３１，３３２が第１及び第２アンテナパターン３２２ａ，３２２ｂそれぞれの第２部位３２２ａ２，３２２ｂ２にそれぞれ結合されるように、蓋３２０にある。本実施の形態では、第１及び第２電極３３１，３３２は、第１及び第２アンテナパターン３２２ａ，３２２ｂにそれぞれ容量結合される。 The RFID module 330 is coupled to the metal film 322 at the handle portion 320b of the lid 320 so as to straddle the first extension portion 323a of the slit 323. More specifically, the RFID module 330 is on the lid 320 such that the first and second electrodes 331, 332 are respectively coupled to the second portions 322a2, 322b2 of the first and second antenna patterns 322a, 322b. . In this embodiment, the first and second electrodes 331, 332 are capacitively coupled to the first and second antenna patterns 322a, 322b, respectively.
　なお、本実施の形態においても、蓋３２０は、金属膜３２２を覆う保護膜を備えてよい。ＲＦＩＤモジュール３３０は、保護膜と金属膜３２２との間にあってよい。これによって、ＲＦＩＤモジュール３３０の蓋３２０からの脱落の可能性を低減できる。 Also in this embodiment, the lid 320 may include a protective film that covers the metal film 322 . The RFID module 330 may be between the protective membrane and the metal membrane 322 . This reduces the possibility of the RFID module 330 falling off the lid 320 .
　［１．３．２　効果等］
　以上述べたように、ＲＦＩＤ機能付き容器３００は、内容物Ｎ１００用の収容空間３１１を有する電気絶縁性の本体３１０と、金属膜３２２を含み収容空間３１１の開口を覆うように本体３１０に取り付けられる蓋３２０と、収容空間３１１の開口の外側にあるように蓋３２０に取り付けられ金属膜３２２に結合される第１及び第２電極３３１，３３２を有するＲＦＩＤモジュール３３０とを備える。 [1.3.2 Effects, etc.]
As described above, the RFID function-equipped container 300 includes an electrically insulating main body 310 having an accommodation space 311 for the content N100, and a metal film 322 attached to the main body 310 so as to cover the opening of the accommodation space 311. It comprises a lid 320 and an RFID module 330 having first and second electrodes 331 , 332 attached to the lid 320 so as to be outside the opening of the receiving space 311 and coupled to the metal film 322 .
　ＲＦＩＤ機能付き容器３００では、蓋３２０の金属膜３２２にＲＦＩＤモジュール３３０が結合されることで、ＲＦＩＤタグとしての機能が実現される。蓋３２０の金属膜３２２は内容物Ｎ１００の保護等のために蓋３２０に形成される金属膜３２２を利用するから、ＲＦＩＤ機能のためだけにアンテナ等を別途設ける必要がない。ＲＦＩＤモジュール３３０は、蓋３２０における収容空間３１１の開口の外側にあるから、意図せずにＲＦＩＤモジュール３３０が蓋３２０から脱落しても、ＲＦＩＤモジュール３３０が内容物Ｎ１００に混入される可能性を低減できる。このように、本実施の形態のＲＦＩＤ機能付き容器３００は、内容物Ｎ１００を収容する本体３１０に金属膜３２２を有する蓋３２０が取り付けられる容器において、意匠性の低減を抑制しつつもＲＦＩＤモジュール３３０が内容物Ｎ１００に混入する可能性を低減できる。 In the RFID function-equipped container 300, the function as an RFID tag is realized by connecting the RFID module 330 to the metal film 322 of the lid 320. Since the metal film 322 of the lid 320 uses the metal film 322 formed on the lid 320 to protect the content N100, etc., there is no need to separately provide an antenna or the like just for the RFID function. Since the RFID module 330 is located outside the opening of the housing space 311 in the lid 320, even if the RFID module 330 falls off the lid 320 unintentionally, the possibility of the RFID module 330 being mixed with the contents N100 is reduced. can. As described above, the RFID function-equipped container 300 of the present embodiment is a container in which the lid 320 having the metal film 322 is attached to the main body 310 that accommodates the content N100. can reduce the possibility of mixing into the contents N100.

The RFID module 330 is on the lid 320 such that the first and second electrodes 331, 332 are coupled to the antenna patterns (first and second antenna patterns 322a, 322b). This configuration can improve the efficiency of wireless communication in the RFID module 330 because the metal film 322 has an antenna pattern.
　ＲＦＩＤ機能付き容器３００において、アンテナパターンは、互いに電気的に独立した第１及び第２アンテナパターン３２２ａ，３２２ｂを含む。ＲＦＩＤモジュール３３０は、第１及び第２電極３３１，３３２が第１及び第２アンテナパターン３２２ａ，３２２ｂにそれぞれ結合されるように、蓋３２０にある。この構成は、ダイポールアンテナを形成できる。 In the RFID function-equipped container 300, the antenna patterns include first and second antenna patterns 322a and 322b that are electrically independent of each other. The RFID module 330 is on the lid 320 such that the first and second electrodes 331, 332 are respectively coupled to the first and second antenna patterns 322a, 322b. This configuration can form a dipole antenna.
　ＲＦＩＤ機能付き容器３００において、第１及び第２アンテナパターン３２２ａ，３２２ｂの形状は、金属膜３２２に形成されるスリット３２３により規定される。スリット３２３は、金属膜３２２において収容空間３１１の開口を覆う所定領域Ｒ３００を避けて配置される。この構成は、金属膜３２２による内容物Ｎ１００の保護機能に影響を及ぼすことなく、第１及び第２アンテナパターン３２２ａ，３２２ｂを設けることができる。 In the RFID function-equipped container 300 , the shapes of the first and second antenna patterns 322 a and 322 b are defined by slits 323 formed in the metal film 322 . The slit 323 is arranged in the metal film 322 so as to avoid the predetermined region R300 covering the opening of the accommodation space 311 . This configuration allows provision of the first and second antenna patterns 322a and 322b without affecting the protection function of the contents N100 by the metal film 322. FIG.
　ＲＦＩＤ機能付き容器３００において、スリット３２３は、収容空間３１１の開口を囲うように形成されて所定領域Ｒ３００から第１及び第２アンテナパターン３２２ａ，３２２ｂを電気的に分離する第１部位３２３ｂと、収容空間３１１の開口の縁部に形成されて第１及び第２アンテナパターン３２２ａ，３２２ｂ間を電気的に分離する第２部位３２３ａ，３２３ｃとを含む。この構成は、第１及び第２アンテナパターン３２２ａ，３２２ｂが内容物Ｎ１００により影響を受ける可能性を低減できる。 In the RFID function-equipped container 300, the slit 323 is formed so as to surround the opening of the accommodation space 311 and electrically separates the first and second antenna patterns 322a and 322b from the predetermined region R300. and second portions 323a and 323c formed at the edge of the opening of the space 311 to electrically separate the first and second antenna patterns 322a and 322b. This configuration can reduce the likelihood that the first and second antenna patterns 322a, 322b will be affected by the content N100.
　ＲＦＩＤ機能付き容器３００において、蓋３２０は、収容空間３１１の開口縁部から外方に突出する持ち手部３２０ｂを有する。ＲＦＩＤモジュール３３０は、持ち手部３２０ｂにある。この構成は、ＲＦＩＤ機能付き容器３００を重ねた場合に、ＲＦＩＤモジュール３３０の機能を損ねる可能性を低減できる。 In the RFID function-equipped container 300 , the lid 320 has a handle portion 320 b protruding outward from the opening edge of the accommodation space 311 . RFID module 330 resides in handle portion 320b. This configuration can reduce the possibility of impairing the function of the RFID module 330 when the containers 300 with RFID function are stacked.
　ＲＦＩＤ機能付き容器３００において、ＲＦＩＤモジュール３３０は、蓋３２０における本体３１０側にある。この構成は、ＲＦＩＤ機能付き容器３００の意匠性が損なわれにくくなる。この構成は、ＲＦＩＤモジュール３３０が脱落しにくくなる。 In the RFID function-equipped container 300 , the RFID module 330 is on the main body 310 side of the lid 320 . With this configuration, the design of the RFID-equipped container 300 is less likely to be impaired. This configuration makes the RFID module 330 less likely to fall off.

　図２１は、実施の形態３の変形例１のＲＦＩＤ機能付き容器の蓋３２０Ａの構成例の底面図である。蓋３２０Ａは、スリット３２３Ａが形成された金属膜３２２Ａを含む。 [1.3.3.1 Modification 1]
FIG. 21 is a bottom view of a configuration example of lid 320A of a container with RFID function according to Modification 1 of Embodiment 3. FIG. The lid 320A includes a metal film 322A with slits 323A formed therein.
　図２１のスリット３２３Ａは、金属膜３２２Ａにおいて本体３１０の収容空間３１１の開口を覆う所定領域Ｒ３００を避けて配置される。図２１のスリット３２３Ａは、図２０のスリット３２３とは形状が異なる。図２１のスリット３２３Ａは、第１延長部３２３ａと、円弧部３２３ｄと、第２及び第３延長部３２３ｅ，３２３ｆとを含む。円弧部３２３ｄは、所定領域Ｒ３００の外周に沿って延びる。図２１では、円弧部３２３ｄの中心角は約１８０度である。第１～第３延長部３２３ａ，３２３ｅ，３２３ｆの各々は、円弧部３２３ｄから蓋３２０Ａの外方に延びている。特に、第１延長部３２３ａは、蓋３２０Ａの持ち手部３２０ｂを２分するように、円弧部３２３ｄの中央部から延びている。第２及び第３延長部３２３ｅ，３２３ｆは、円弧部３２３ｄの両端から蓋３２０Ａの外方に延びている。第２及び第３延長部３２３ｅ，３２３ｆは一直線上に並ぶ。 The slit 323A in FIG. 21 is arranged in the metal film 322A so as to avoid the predetermined region R300 covering the opening of the accommodation space 311 of the main body 310. A slit 323A in FIG. 21 is different in shape from the slit 323 in FIG. The slit 323A of FIG. 21 includes a first extension portion 323a, an arc portion 323d, and second and third extension portions 323e and 323f. Arc portion 323d extends along the outer circumference of predetermined region R300. In FIG. 21, the central angle of the arc portion 323d is approximately 180 degrees. Each of the first to third extensions 323a, 323e, 323f extends outward from the lid 320A from the arc portion 323d. In particular, the first extension portion 323a extends from the central portion of the arc portion 323d so as to bisect the handle portion 320b of the lid 320A. The second and third extension portions 323e and 323f extend outward from the lid 320A from both ends of the arc portion 323d. The second and third extensions 323e, 323f are aligned.
　金属膜３２２Ａは、スリット３２３Ａにより、金属膜３２２Ａの外縁部の１／４に対応する第１及び第２辺部３２２ｅ，３２２ｆと、収容空間３１１の開口を覆う中央部３２２ｄとに分割される。中央部３２２ｄは、金属膜３２２において収容空間３１１の開口を覆う所定領域Ｒ３００及び金属膜３２２Ａの外縁部の１／２を含む。第１辺部３２２ｅは、蓋３２０Ａの主部３２０ａにある第１部位３２２ｅ１と、蓋３２０Ａの持ち手部３２０ｂにある第２部位３２２ｅ２とを含む。第２辺部３２２ｆは、蓋３２０Ａの主部３２０ａにある第１部位３２２ｆ１と、蓋３２０Ａの持ち手部３２０ｂにある第２部位３２２ｆ２とを含む。金属膜３２２Ａにおいて、第１及び第２辺部３２２ｅ，３２２ｆと中央部３２２ｄとは互いに電気的に分離されている。第１及び第２辺部３２２ｅ，３２２ｆは、ＲＦＩＤモジュール３３０のためのアンテナパターンとして用いることができる。図２１では、第１及び第２辺部３２２ｅ，３２２ｆが、互いに電気的に独立した第１及び第２アンテナパターンを構成する。第１辺部３２２ｅを第１アンテナパターン３２２ｅといい、第２辺部３２２ｆを第２アンテナパターン３２２ｆということがある。 The metal film 322A is divided by the slit 323A into first and second side portions 322e and 322f corresponding to 1/4 of the outer edge portion of the metal film 322A and a central portion 322d covering the opening of the accommodation space 311. The center portion 322d includes a predetermined region R300 covering the opening of the accommodation space 311 in the metal film 322 and 1/2 of the outer edge portion of the metal film 322A. The first side portion 322e includes a first portion 322e1 on the main portion 320a of the lid 320A and a second portion 322e2 on the handle portion 320b of the lid 320A. The second side portion 322f includes a first portion 322f1 on the main portion 320a of the lid 320A and a second portion 322f2 on the handle portion 320b of the lid 320A. In the metal film 322A, the first and second side portions 322e and 322f and the central portion 322d are electrically isolated from each other. The first and second sides 322e, 322f can be used as antenna patterns for the RFID module 330. FIG. In FIG. 21, the first and second sides 322e and 322f form first and second antenna patterns that are electrically independent of each other. The first side portion 322e may be referred to as the first antenna pattern 322e, and the second side portion 322f may be referred to as the second antenna pattern 322f.
　第１及び第２アンテナパターン３２２ｅ，３２２ｆの形状は、金属膜３２２Ａに形成されるスリット３２３Ａにより規定される。スリット３２３Ａにおいて、円弧部３２３ｄ及び第２及び第３延長部３２３ｅ，３２３ｆは、収容空間３１１の開口を囲うように形成されて所定領域Ｒ３００から第１及び第２アンテナパターン３２２ｅ，３２２ｆを電気的に分離する第１部位である。第１延長部３２３ａは、収容空間３１１の開口の縁部に形成されて第１及び第２アンテナパターン３２２ｅ，３２２ｆ間を電気的に分離する第２部位である。 The shapes of the first and second antenna patterns 322e and 322f are defined by slits 323A formed in the metal film 322A. In the slit 323A, the arc portion 323d and the second and third extension portions 323e and 323f are formed so as to surround the opening of the accommodation space 311 and electrically connect the first and second antenna patterns 322e and 322f from the predetermined region R300. It is the first part to be separated. The first extension part 323a is a second part formed at the edge of the opening of the accommodation space 311 and electrically separating the first and second antenna patterns 322e and 322f.
　変形例１では、円弧部３２３ｄの長さ及び第２及び第３延長部３２３ｅ，３２３ｆの位置を適宜設定することで、第１及び第２アンテナパターン３２２ｅ，３２２ｆの長さを所望の長さに設定することが可能である。これによって、アンテナパターンの長さの自由度が向上する。そのため、ＲＦＩＤモジュール３３０の通信周波数に対応する波長に対して適した長さにアンテナパターンの長さを設定できる可能性が高くなる。ＲＦＩＤモジュール３３０の通信周波数に対応する波長に対して適した長さは、例えば、ＲＦＩＤモジュール３３０の通信周波数に対応する波長の１／２である。 In Modified Example 1, the length of the arc portion 323d and the positions of the second and third extension portions 323e and 323f are appropriately set so that the lengths of the first and second antenna patterns 322e and 322f are set to desired lengths. Can be set. This improves the degree of freedom for the length of the antenna pattern. Therefore, it is more likely that the length of the antenna pattern can be set to a length suitable for the wavelength corresponding to the communication frequency of the RFID module 330 . A suitable length for the wavelength corresponding to the communication frequency of RFID module 330 is, for example, ½ of the wavelength corresponding to the communication frequency of RFID module 330 .

The central portion 322g includes a predetermined region R300 that covers the opening of the accommodation space 311 in the metal film 322B. The peripheral portion 322h has a shape surrounding the central portion 322g, but is separated at the first extension portion 323a. Accordingly, the peripheral portion 322h has first and second ends 322ha and 322hb facing each other across the first extension portion 323a. Perimeter 322 h can be used as a loop antenna pattern for RFID module 330 . Below, peripheral part 322h may be called loop antenna pattern 322h.
　ＲＦＩＤモジュール３３０は、蓋３２０Ｂにおいて、スリット３２３Ｂの第１延長部３２３ａを跨ぐように金属膜３２２Ｂに結合される。より詳細には、ＲＦＩＤモジュール３３０は、第１及び第２電極３３１，３３２がループアンテナパターン３２２ｈの第１端３２２ｈａ及び第２端３２２ｈｂにそれぞれ結合されるように、蓋３２０Ｂの持ち手部３２０ｂにある。第１及び第２電極３３１，３３２は、ループアンテナパターン３２２ｈの第１端３２２ｈａ及び第２端３２２ｈｂにそれぞれ容量結合される。 The RFID module 330 is coupled to the metal film 322B in the lid 320B so as to straddle the first extension 323a of the slit 323B. More specifically, the RFID module 330 is attached to the handle portion 320b of the lid 320B such that the first and second electrodes 331, 332 are respectively coupled to the first end 322ha and the second end 322hb of the loop antenna pattern 322h. be. The first and second electrodes 331, 332 are capacitively coupled to the first end 322ha and the second end 322hb of the loop antenna pattern 322h, respectively.
　図２２の蓋３２０Ｂでは、金属膜３２２Ｂのループアンテナパターン３２２ｈは、ＲＦＩＤモジュール３３０に対して、ループアンテナとして機能する。 In the lid 320B of FIG. 22, the loop antenna pattern 322h of the metal film 322B functions as a loop antenna for the RFID module 330.

In FIG. 24, the first and second parts 322j and 322k form electrically independent first and second antenna patterns. Hereinafter, the first portion 322j may be referred to as the first antenna pattern 322j, and the second portion 322k may be referred to as the second antenna pattern 322k.
　ＲＦＩＤモジュール３３０は、蓋３２０Ｄにおいて、スリット３２３Ｄを跨ぐように金属膜３２２Ｄに結合される。より詳細には、ＲＦＩＤモジュール３３０は、第１及び第２電極３３１，３３２が第１及び第２アンテナパターン３２２ｊ，３２２ｋにそれぞれ結合されるように、蓋３２０Ｄにある。図２４においても、ＲＦＩＤモジュール３３０は、蓋３２０Ｄの持ち手部３２０ｂにある。第１及び第２電極３３１，３３２は、第１及び第２アンテナパターン３２２ｊ，３２２ｋにそれぞれ容量結合される。 The RFID module 330 is coupled to the metal film 322D across the slit 323D in the lid 320D.

Also in FIG. 24, the RFID module 330 is located in the handle portion 320b of the lid 320D. The first and second electrodes 331, 332 are capacitively coupled to the first and second antenna patterns 322j, 322k, respectively.
　図２４の蓋３２０Ｄでは、金属膜３２２Ｄの第１及び第２アンテナパターン３２２ｊ，３２２ｋは、ＲＦＩＤモジュール３３０に対して、ダイポールアンテナとして機能する。 In the lid 320D of FIG. 24, the first and second antenna patterns 322j and 322k of the metal film 322D function as dipole antennas for the RFID module 330.
　図２４の蓋３２０Ｄでは、スリット３２３Ｄが所定方向に沿って形成されている。特に、スリット３２３Ｄが所定方向に沿って一直線上に形成されている。そのため、複数の蓋３２０Ｄにスリット３２３Ｄをまとめて形成することが可能となる。次に、図２５を参照して蓋３２０Ｄの製造方法の一例について説明する。図２５は、図２４の蓋３２０Ｄの製造方法の一例の説明図である。蓋３２０Ｄの製造方法の一例は、第１工程、第２工程、及び第３工程を含む。 A slit 323D is formed along a predetermined direction in the lid 320D of FIG. In particular, the slit 323D is formed on a straight line along a predetermined direction. Therefore, it is possible to collectively form slits 323D in a plurality of lids 320D. Next, an example of a method for manufacturing the lid 320D will be described with reference to FIG. 25A and 25B are explanatory diagrams of an example of a method of manufacturing the lid 320D of FIG. An example of a method for manufacturing the lid 320D includes first, second, and third steps.
　第１工程は、複数の蓋３２０Ｄを形成可能な大きさのシート３４０を用意する。図２５では、シート３４０は、６枚の蓋３２０Ｄを形成可能な大きさである。より詳細には、シート３４０は、２×３のマトリクス状に並んだ蓋３２０Ｄの形成予定領域Ｒ３２０を含む。シート３４０は、蓋３２０Ｄの基材３２１の基礎となる基材層に、蓋３２０Ｄの金属膜３２２Ｄの基礎となる金属層を形成して構成される。シート３４０における形成予定領域Ｒ３２０以外の部位Ｒ３２１は、蓋３２０Ｄには使用されない部位である。 The first step is to prepare a sheet 340 having a size capable of forming a plurality of lids 320D. In FIG. 25, sheet 340 is sized to form six lids 320D. More specifically, the sheet 340 includes formation planned regions R320 for the lids 320D arranged in a 2×3 matrix. The sheet 340 is configured by forming a metal layer, which is the base of the metal film 322D of the lid 320D, on a base layer, which is the base of the base 321 of the lid 320D. A portion R321 other than the formation scheduled region R320 on the sheet 340 is a portion not used for the lid 320D.
　第２工程は、第１工程で用意したシート３４０の金属層に溝３５０を形成する。溝３５０において各形成予定領域Ｒ３２０に対応する部分がスリット３２３Ｄとなる。図２５では、所定方向に並ぶ複数（図２５では３つ）の形成予定領域Ｒ３２０に、所定方向に沿った１つの溝３５０が形成される。これによって、複数（図２５では３つ）のスリット３２３Ｄがまとめて形成される。 The second step is to form grooves 350 in the metal layer of the sheet 340 prepared in the first step. The portions of the grooves 350 corresponding to the respective formation-scheduled regions R320 serve as slits 323D. In FIG. 25, one groove 350 is formed along a predetermined direction in a plurality of (three in FIG. 25) formation scheduled regions R320 aligned in a predetermined direction. As a result, a plurality of (three in FIG. 25) slits 323D are collectively formed.
　第３工程は、複数の蓋３２０Ｄの形成予定領域Ｒ３２０に複数のＲＦＩＤモジュール３３０をそれぞれ配置する。 In the third step, a plurality of RFID modules 330 are arranged in formation-planned regions R320 of a plurality of lids 320D.
　第３工程の後、シート３４０は切断されて、複数の蓋３２０Ｄに分離される。シート３４０の切断は、シート３４０を複数の本体３１０にまとめて貼り付けた後に実行されてよい。 After the third step, the sheet 340 is cut and separated into a plurality of lids 320D. Cutting the sheet 340 may be performed after the sheet 340 is attached to the plurality of bodies 310 together.
　以上述べた変形例４では、スリット３２３Ｄは、金属膜３２２Ｄにおける収容空間３１１の開口の縁部に対応する部位に所定方向に沿って形成されて第１及び第２アンテナパターン３２２ｊ，３２２ｋ間を電気的に分離する。この構成は、複数の蓋３２０Ｄへのスリット３２３Ｄの形成をまとめて行うことを可能にする。 In Modified Example 4 described above, the slit 323D is formed along a predetermined direction in a portion of the metal film 322D corresponding to the edge of the opening of the accommodation space 311 to electrically connect the first and second antenna patterns 322j and 322k. physically separated. This configuration makes it possible to collectively form the slits 323D in the plurality of lids 320D.

The first electrode pattern 441 includes a first electrode portion 441a and a first wiring portion 441b. The first electrode portion 441 a is located at a portion of the insulating material 423 that overlaps the metal film 422 . The first electrode portion 441 a is capacitively coupled with the metal film 422 . The first electrode part 441 a faces the metal film 422 and is larger than the first electrode 431 of the RFID module 430 . The first wiring portion 441 b extends from the first electrode portion 441 a to a portion of the insulating material 423 that does not overlap the metal film 422 . The first wiring portion 441 b is used to connect the first electrode portion 441 a and the first electrode 431 of the RFID module 430 . The second electrode pattern 442 includes a second electrode portion 442a and a second wiring portion 442b.

　ＲＦＩＤ機能付き容器４００では、金属膜４２２にスリットを設けていない。金属膜４２２にスリットを設けようとした場合には、金属膜４２２の厚みが制限される場合がある。ＲＦＩＤ機能付き容器４００では、金属膜４２２にスリットを設ける等の加工をしなくて済むから、金属膜４２２の設計の自由度を向上できる。例えば、金属膜４２２の厚みを所望の厚みに設定できて、外部要因に起因する内容物の変化を防止する作用の向上が図れる。 A slit is not provided in the metal film 422 in the RFID function-equipped container 400 . When it is attempted to provide slits in the metal film 422, the thickness of the metal film 422 may be limited. In the RFID function-equipped container 400, the metal film 422 does not need to be processed such as forming slits, so that the metal film 422 can be designed more freely. For example, the thickness of the metal film 422 can be set to a desired thickness, and the effect of preventing changes in the contents due to external factors can be improved.

The first electrode pattern 541 includes a first electrode portion 541a and a first wiring portion 541b. The first electrode part 541 a faces the metal film 522 and is larger than the first electrode 531 of the RFID module 530 . The first electrode portion 541 a is formed using the second corner portion 513 b of the flange portion 513 . As a result, the area of the first electrode portion 541a can be increased, and the capacitive coupling between the metal film 522 and the first electrode portion 541a can be improved. The first wiring portion 541b extends from the first electrode portion 541a to the first corner portion 513a of the flange portion 513 .

　ＲＦＩＤ機能付き容器５００では、金属膜５２２にスリットを設けていない。金属膜５２２にスリットを設けようとした場合には、金属膜５２２の厚みが制限される場合がある。ＲＦＩＤ機能付き容器５００では、金属膜５２２にスリットを設ける等の加工をしなくて済むから、金属膜５２２の設計の自由度を向上できる。例えば、金属膜５２２の厚みを所望の厚みに設定できて、外部要因に起因する内容物の変化を防止する作用の向上が図れる。 A slit is not provided in the metal film 522 in the RFID function-equipped container 500 . When it is attempted to provide slits in the metal film 522, the thickness of the metal film 522 may be limited. In the RFID function-equipped container 500, the metal film 522 does not need to be provided with slits or the like, so the degree of freedom in designing the metal film 522 can be improved. For example, the thickness of the metal film 522 can be set to a desired thickness, and the effect of preventing changes in the contents due to external factors can be improved.
　次に、図２９を参照してＲＦＩＤモジュール５３０の位置について説明する。図２９は、本体５１０の底面図である。ＲＦＩＤモジュール５３０は、本体５１０における収容空間５１１の開口の外側にある。より詳細には、ＲＦＩＤモジュール５３０は、本体５１０のフランジ部５１３にある。ＲＦＩＤモジュール５３０は、第１及び第２電極５３１，５３２が第１及び第２電極パターン５４１，５４２の配線部５４１ｂ，５４２ｂにそれぞれ結合されるように、フランジ部５１３の第１角部５１３ａにある。ＲＦＩＤモジュール５３０は、第１及び第２電極パターン５４１，５４２を介して金属膜５２２に結合される。これによって、ＲＦＩＤモジュール５３０は、金属膜５２２を用いた通信が可能となる。 Next, the position of the RFID module 530 will be described with reference to FIG. 29 is a bottom view of main body 510. FIG. The RFID module 530 is outside the opening of the accommodation space 511 in the main body 510 . More specifically, RFID module 530 resides on flange portion 513 of body 510 . The RFID module 530 is located at the first corner 513a of the flange portion 513 such that the first and second electrodes 531 and 532 are coupled to the wiring portions 541b and 542b of the first and second electrode patterns 541 and 542, respectively. . The RFID module 530 is coupled to the metal film 522 through the first and second electrode patterns 541,542. This enables the RFID module 530 to communicate using the metal film 522 .
　本実施の形態において、ＲＦＩＤモジュール５３０は、本体５１０のフランジ部５１３にある。そのため、ＲＦＩＤモジュール５３０は、ＲＦＩＤモジュール５３０が蓋５２０において本体５１０の収容空間５１１と重なる部位にある場合に比べて、別のＲＦＩＤ機能付き容器５００からの影響、特に、内容物Ｎ１００からの影響を受けにくい。したがって、ＲＦＩＤモジュール５３０の機能を損ねる可能性を低減できる。 In this embodiment, the RFID module 530 is located on the flange portion 513 of the body 510 . Therefore, the RFID module 530 is less affected by another RFID-equipped container 500, particularly by the contents N100, than when the RFID module 530 is located in the lid 520 overlapping the housing space 511 of the main body 510. Hard to accept. Therefore, the possibility of impairing the function of the RFID module 530 can be reduced.
　［１．５．２　効果等］
　以上述べたように、ＲＦＩＤ機能付き容器５００は、内容物Ｎ１００用の収容空間５１１を有する電気絶縁性の本体５１０と、金属膜５２２を含み収容空間５１１の開口を覆うように本体５１０に取り付けられる蓋５２０と、収容空間５１１の開口の外側にあるように本体５１０に取り付けられ金属膜５２２に結合される第１及び第２電極５３１，５３２を有するＲＦＩＤモジュール５３０とを備える。 [1.5.2 Effects, etc.]
As described above, the RFID function-equipped container 500 includes an electrically insulating main body 510 having a storage space 511 for the content N100, and a metal film 522 attached to the main body 510 so as to cover the opening of the storage space 511. It comprises a lid 520 and an RFID module 530 having first and second electrodes 531 , 532 attached to the body 510 so as to be outside the opening of the receiving space 511 and coupled to the metal film 522 .
　ＲＦＩＤ機能付き容器５００では、蓋５２０の金属膜５２２にＲＦＩＤモジュール５３０が結合されることで、ＲＦＩＤタグとしての機能が実現される。内容物Ｎ１００の保護等のために蓋５２０に形成される金属膜５２２を利用するから、ＲＦＩＤ機能のためだけにアンテナ等を別途設ける必要がない。ＲＦＩＤモジュール５３０は、本体５１０における収容空間５１１の開口の外側にあるから、意図せずにＲＦＩＤモジュール５３０が本体５１０から脱落しても、ＲＦＩＤモジュール５３０が内容物Ｎ１００に混入される可能性を低減できる。このように、本実施の形態のＲＦＩＤ機能付き容器５００は、内容物Ｎ１００を収容する本体５１０に金属膜５２２を有する蓋５２０が取り付けられる容器において、意匠性の低減を抑制しつつもＲＦＩＤモジュール５３０が内容物Ｎ１００に混入する可能性を低減できる。 In the RFID function-equipped container 500, the RFID module 530 is coupled to the metal film 522 of the lid 520, thereby realizing the function as an RFID tag. Since the metal film 522 formed on the lid 520 is used to protect the contents N100, etc., there is no need to separately provide an antenna or the like just for the RFID function. Since the RFID module 530 is located outside the opening of the accommodation space 511 in the main body 510, even if the RFID module 530 unintentionally falls out of the main body 510, the possibility of the RFID module 530 being mixed with the contents N100 is reduced. can. As described above, the RFID function-equipped container 500 of the present embodiment is a container in which the lid 520 having the metal film 522 is attached to the main body 510 that accommodates the content N100, and the RFID module 530 can reduce the possibility of mixing into the contents N100.
　ＲＦＩＤ機能付き容器５００において、本体５１０は、金属膜５２２に結合される第１及び第２電極パターン５４１，５４２を有する。ＲＦＩＤモジュール５３０の第１及び第２電極５３１，５３２は、第１及び第２電極パターン５４１，５４２にそれぞれ結合される。この構成は、金属膜５２２にスリットを設ける等の加工をしなくて済むから、金属膜５２２の設計の自由度を向上できる。例えば、金属膜５２２の厚みを所望の厚みに設定できて、外部要因に起因する内容物の変化を防止する作用の向上が図れる。 In the RFID function-equipped container 500 , the main body 510 has first and second electrode patterns 541 and 542 coupled to the metal film 522 . The first and second electrodes 531, 532 of the RFID module 530 are coupled to the first and second electrode patterns 541, 542 respectively. This configuration does not require processing such as forming slits in the metal film 522, so that the degree of freedom in designing the metal film 522 can be improved. For example, the thickness of the metal film 522 can be set to a desired thickness, and the effect of preventing changes in the contents due to external factors can be improved.
　ＲＦＩＤ機能付き容器５００において、本体５１０は、第１及び第２電極パターン５４１，５４２を有する。第１及び第２電極パターン５４１，５４２は、金属膜５２２に対向する。ＲＦＩＤモジュール５３０は、第１及び第２電極５３１，５３２が第１及び第２電極パターン５４１，５４２にそれぞれ結合されるように、本体５１０にある。この構成は、金属膜５２２にスリットを設ける等の加工をしなくて済むから、金属膜５２２の設計の自由度を向上できる。例えば、金属膜５２２の厚みを所望の厚みに設定できて、外部要因に起因する内容物の変化を防止する作用の向上が図れる。また、蓋５２０を本体５１０から剥離することで、ＲＦＩＤモジュール５３０から金属膜５２２が分離される。そのため、ＲＦＩＤ機能が無効化される。つまり、蓋５２０を本体５１０から剥離するかどうかで、ＲＦＩＤ機能の有効と無効との選択が可能である。 In the container 500 with RFID function, the main body 510 has first and second electrode patterns 541 and 542 . The first and second electrode patterns 541 and 542 face the metal film 522 . RFID module 530 resides in body 510 such that first and second electrodes 531, 532 are coupled to first and second electrode patterns 541, 542, respectively. This configuration does not require processing such as forming slits in the metal film 522, so that the degree of freedom in designing the metal film 522 can be improved. For example, the thickness of the metal film 522 can be set to a desired thickness, and the effect of preventing changes in the contents due to external factors can be improved. Also, the metal film 522 is separated from the RFID module 530 by peeling off the lid 520 from the main body 510 . Therefore, the RFID function is disabled. In other words, whether the RFID function is enabled or disabled can be selected depending on whether the lid 520 is peeled off from the main body 510 .
　実施の形態４において、第１電極パターン５４１は、金属膜５２２に対向しＲＦＩＤモジュール５３０の第１電極５３１より大きい第１電極部５４１ａと、第１電極部５４１ａとＲＦＩＤモジュール５３０の第１電極５３１とを接続する第１配線部５４１ｂとを含む。第２電極パターン５４２は、金属膜５２２に対向しＲＦＩＤモジュール５３０の第２電極５３２より大きい第２電極部５４２ａと、第２電極部５４２ａとＲＦＩＤモジュール５３０の第２電極５３２とを接続する第２配線部５４２ｂとを含む。この構成は、ＲＦＩＤモジュール５３０と金属膜５２２との結合を強くできる。 In the fourth embodiment, the first electrode pattern 541 includes a first electrode portion 541 a that faces the metal film 522 and is larger than the first electrode 531 of the RFID module 530 , and the first electrode portion 541 a and the first electrode 531 of the RFID module 530 . and a first wiring portion 541b for connecting the . The second electrode pattern 542 includes a second electrode portion 542 a that faces the metal film 522 and is larger than the second electrode 532 of the RFID module 530 , and a second electrode portion 542 a that connects the second electrode portion 542 a and the second electrode 532 of the RFID module 530 . and a wiring portion 542b. This configuration can strengthen the bond between the RFID module 530 and the metal film 522 .
　ＲＦＩＤ機能付き容器５００において、本体５１０は、収容空間５１１の開口縁部から外方に突出するフランジ部５１３を有する。金属膜５２２は、フランジ部５１３を覆う。ＲＦＩＤモジュール５３０と第１及び第２電極パターン５４１，５４２とは、フランジ部５１３にある。この構成は、ＲＦＩＤ機能付き容器５００を重ねた場合に、ＲＦＩＤモジュール５３０の機能を損ねる可能性を低減できる。 In the RFID function-equipped container 500 , the main body 510 has a flange portion 513 that protrudes outward from the opening edge of the accommodation space 511 . A metal film 522 covers the flange portion 513 . The RFID module 530 and the first and second electrode patterns 541 , 542 are on the flange portion 513 . This configuration can reduce the possibility of impairing the function of the RFID module 530 when the containers 500 with RFID function are stacked.

Note that the content N100 is, for example, an article for commercial transactions. Contents N100 can be liquid, solid, sol, gel, or combinations thereof. Examples of contents N100 include food, medicines, medical or orthodontic appliances, and the like. Foods include foods that can be provided in a container, such as yogurt, pudding, and instant foods. Medical or corrective devices include contact lenses.
　以下、実施の形態６のＲＦＩＤ機能付き容器６００の構成についてさらに説明する。図３０に示すように、ＲＦＩＤ機能付き容器６００は、本体６１０と、蓋６２０と、ＲＦＩＤモジュール６３０とを備える。 The configuration of the RFID function-equipped container 600 of Embodiment 6 will be further described below. As shown in FIG. 30 , RFID function-equipped container 600 includes main body 610 , lid 620 , and RFID module 630 .
　図３１は、蓋６２０の構成例の底面図である。図３２は、ＲＦＩＤ機能付き容器６００において蓋６２０を本体６１０から剥離した状態を示す斜視図である。 31 is a bottom view of a configuration example of the lid 620. FIG. FIG. 32 is a perspective view showing a state in which the lid 620 is peeled off from the main body 610 in the container 600 with RFID function.
　図３２に示すように、本体６１０は、内容物Ｎ１００用の収容空間６１１を有する。本体６１０は、電気絶縁性を有する。本体６１０は、例えば、紙、樹脂材料、又はガラス等の誘電体材料から形成される。樹脂材料は、例えば、発泡スチロールを含む。本体６１０は、有底の筒状部６１２と、フランジ部６１３とを有する。筒状部６１２は、収容空間６１１を規定する。筒状部６１２は、円筒形状である。フランジ部６１３は、収容空間６１１の開口縁部から外方に突出する。フランジ部６１３の外形形状は、正方形状である。 As shown in FIG. 32, the main body 610 has an accommodation space 611 for the contents N100. Body 610 is electrically insulating. The main body 610 is made of dielectric material such as paper, resin material, or glass, for example. The resin material includes expanded polystyrene, for example. The main body 610 has a bottomed tubular portion 612 and a flange portion 613 . The tubular portion 612 defines a housing space 611 . The tubular portion 612 is cylindrical. The flange portion 613 protrudes outward from the opening edge of the housing space 611 . The outer shape of the flange portion 613 is square.
　図３０に示すように、蓋６２０は、本体６１０に、収容空間６１１の開口を覆うように取り付けられる。図３０の蓋６２０は、剥離可能に本体６１０に取り付けられる。蓋６２０は、本体６１０の収容空間６１１から内容物Ｎ１００を取り出す際に、本体６１０から剥離される。蓋６２０は全体的に可撓性を有する。蓋６２０は、基材６２１と、金属膜６２２とを含む。基材６２１は、収容空間６１１の開口を覆う。特に、基材６２１は、収容空間６１１の開口及びフランジ部６１３を全体的に覆う。基材６２１の外形形状は、正方形状である。基材６２１は、例えば、紙又はプラスチック等の誘電体材料から形成される。金属膜６２２は、本体６１０の収容空間６１１の開口を覆う。金属膜６２２は、収容空間６１１の開口及びフランジ部６１３を全体的に覆う。金属膜６２２は、基材６２１における本体６１０側の面にある。金属膜６２２は、外部要因に起因する内容物の変化を防止する作用を有し得る。このように、金属膜６２２は、収容空間６１１の開口を覆うことで、内容物Ｎ１００を保護する。金属膜６２２の材料としては、アルミニウム及びアルミニウムを含む合金が挙げられる。蓋６２０は、接着剤により本体６１０の収容空間６１１の開口の周縁部分に取り付けられる。図３０では、蓋６２０は、本体６１０のフランジ部６１３に接着剤で取り付けられる。接着剤は、蓋６２０においてフランジ部６１３に対向する領域に塗布される。 As shown in FIG. 30, the lid 620 is attached to the main body 610 so as to cover the opening of the accommodation space 611. Lid 620 in FIG. 30 is releasably attached to body 610 . The lid 620 is peeled off from the main body 610 when the content N100 is taken out from the accommodation space 611 of the main body 610 . Lid 620 is generally flexible. Lid 620 includes base material 621 and metal film 622 . The base material 621 covers the opening of the accommodation space 611 . In particular, the base material 621 entirely covers the opening of the accommodation space 611 and the flange portion 613 . The outer shape of the base material 621 is square. Substrate 621 is formed from a dielectric material such as, for example, paper or plastic. The metal film 622 covers the opening of the accommodation space 611 of the main body 610 . The metal film 622 entirely covers the opening of the housing space 611 and the flange portion 613 . The metal film 622 is on the surface of the base material 621 on the main body 610 side. The metal film 622 can act to prevent changes in the contents due to external factors. Thus, the metal film 622 protects the content N100 by covering the opening of the accommodation space 611. FIG. Materials for the metal film 622 include aluminum and alloys containing aluminum. The lid 620 is attached to the periphery of the opening of the accommodation space 611 of the main body 610 with an adhesive. In FIG. 30, the lid 620 is adhesively attached to the flange portion 613 of the body 610 . The adhesive is applied to a region of lid 620 facing flange portion 613 .
　図３１に示すように、金属膜６２２は、剥離部６２２ａと、残留部（第１及び第２残留部）６２２ｂ，６２２ｃとを有する。剥離部６２２ａは、金属膜６２２において、蓋６２０を本体６１０から剥離した際に蓋６２０から剥離されて本体６１０に残る部分である。剥離部６２２ａは、金属膜６２２において本体６１０の収容空間６１１の開口を覆う所定領域Ｒ６００を避けて配置される。剥離部６２２ａは、所定領域Ｒ６００を囲う円環状である。第１及び第２残留部６２２ｂ，６２２ｃは、金属膜６２２において、蓋６２０を本体６１０から剥離した際に蓋６２０から剥離されずに残る部分である。第１残留部６２２ｂは、剥離部６２２ａより内側にある。第１残留部６２２ｂは、金属膜６２２の中央部分に対応する。第１残留部６２２ｂは、円形状である。第１残留部６２２ｂは、金属膜６２２において本体６１０の収容空間６１１の開口を覆う所定領域Ｒ６００を含む。第２残留部６２２ｃは、剥離部６２２ａより外側にある。第２残留部６２２ｃは、金属膜６２２の周辺部分に対応する。第２残留部６２２ｃには、スリット６２３を構成する溝部６２３ａが形成される。溝部６２３ａは、金属膜６２２の角部にあって、剥離部６２２ａから金属膜６２２の外方に延びる。溝部６２３ａは、金属膜６２２を貫通する。第２残留部６２２ｃは、剥離部６２２ａを囲う形状であるが、溝部６２３ａにおいて分離されている。これによって、第２残留部６２２ｃは、溝部６２３ａを挟んで対向する第１及び第２端６２２ｃａ，６２２ｃｂを有する。第２残留部６２２ｃは、剥離部６２２ａが蓋６２０から剥離されることで、アンテナパターンを構成する。特に、本実施の形態では、第２残留部６２２ｃは、剥離部６２２ａが蓋６２０から剥離されることで、ループアンテナパターンを構成する。 As shown in FIG. 31, the metal film 622 has a stripped portion 622a and residual portions (first and second residual portions) 622b and 622c. The peeled portion 622 a is a portion of the metal film 622 that is peeled off from the lid 620 and remains on the main body 610 when the lid 620 is peeled off from the main body 610 . The stripped portion 622 a is arranged in the metal film 622 so as to avoid the predetermined region R 600 covering the opening of the housing space 611 of the main body 610 . The peeled portion 622a has an annular shape surrounding the predetermined region R600. The first and second remaining portions 622 b and 622 c are portions of the metal film 622 that remain without being separated from the lid 620 when the lid 620 is separated from the main body 610 . The first remaining portion 622b is inside the stripped portion 622a. The first remaining portion 622b corresponds to the central portion of the metal film 622. As shown in FIG. The first remaining portion 622b is circular. The first remaining portion 622b includes a predetermined region R600 covering the opening of the accommodation space 611 of the main body 610 in the metal film 622. As shown in FIG. The second remaining portion 622c is outside the stripped portion 622a. The second residual portion 622 c corresponds to the peripheral portion of the metal film 622 . A groove portion 623a forming the slit 623 is formed in the second remaining portion 622c. The groove portion 623a is located at the corner of the metal film 622 and extends outward from the metal film 622 from the peeled portion 622a. The groove 623 a penetrates the metal film 622 . The second remaining portion 622c has a shape surrounding the peeled portion 622a, but is separated at the groove portion 623a. Thus, the second remaining portion 622c has first and second ends 622ca and 622cb facing each other across the groove portion 623a. The second remaining portion 622c forms an antenna pattern by peeling off the peeling portion 622a from the lid 620. As shown in FIG. In particular, in the present embodiment, the second remaining portion 622c forms a loop antenna pattern by peeling off the peeling portion 622a from the lid 620 .
　ＲＦＩＤモジュール６３０は、蓋６２０において、スリット６２３の溝部６２３ａを跨ぐように金属膜６２２に結合される。より詳細には、ＲＦＩＤモジュール６３０は、第１及び第２電極６３１，６３２が金属膜６２２の第２残留部６２２ｃの第１端６２２ｃａ及び第２端６２２ｃｂにそれぞれ結合されるように、蓋６２０にある。第１及び第２電極６３１，６３２は、第２残留部６２２ｃの第１端６２２ｃａ及び第２端６２２ｃｂにそれぞれ容量結合される。 The RFID module 630 is coupled to the metal film 622 in the lid 620 so as to straddle the groove 623a of the slit 623 . More specifically, the RFID module 630 is attached to the lid 620 such that the first and second electrodes 631, 632 are respectively coupled to the first end 622ca and the second end 622cb of the second remnant portion 622c of the metal film 622. be. The first and second electrodes 631, 632 are capacitively coupled to the first end 622ca and the second end 622cb of the second residual portion 622c, respectively.
　図３１の蓋６２０では、金属膜６２２にアンテナパターンが形成されておらず、ＲＦＩＤモジュール６３０は、金属膜６２２を利用した通信を行うことができない。そのため、ＲＦＩＤ機能は無効化されている。 In the lid 620 of FIG. 31, no antenna pattern is formed on the metal film 622, and the RFID module 630 cannot perform communication using the metal film 622. Therefore, the RFID function is disabled.
　図３２に示すように、金属膜６２２において、剥離部６２２ａは、蓋６２０を本体６１０から剥離する際に本体６１０に残留することで蓋６２０から除去される。一方で、第１及び第２残留部６２２ｂ，６２２ｃは、蓋６２０を本体６１０から剥離しても蓋６２０に残留する。図３２に示すように、金属膜６２２は、蓋６２０を本体６１０から剥離する際に選択的に除去される。例えば、金属膜６２２の剥離部６２２ａと第１及び第２残留部６２２ｂ，６２２ｃとで、蓋６２０と本体６１０との間の接着剤の強度を異ならせることで、剥離部６２２ａを蓋６２０から剥離させながら、第１及び第２残留部６２２ｂ，６２２ｃを蓋６２０に残すことができる。具体的には、金属膜６２２の剥離部６２２ａにおいて、第１及び第２残留部６２２ｂ，６２２ｃよりも接着剤の強度を強くすればよい。また、必要に応じて、剥離部６２２ａと第１及び第２残留部６２２ｂ，６２２ｃとの境界にミシン目を形成してもよい。 As shown in FIG. 32 , in the metal film 622 , the stripped portion 622 a is removed from the lid 620 by remaining on the body 610 when the lid 620 is peeled off from the body 610 . On the other hand, the first and second remaining portions 622b and 622c remain on the lid 620 even after the lid 620 is separated from the main body 610. FIG. As shown in FIG. 32, metal film 622 is selectively removed when peeling lid 620 from body 610 . For example, the peeled portion 622a and the first and second remaining portions 622b and 622c of the metal film 622 are different in strength of the adhesive between the lid 620 and the main body 610, thereby peeling the peeled portion 622a from the lid 620. The first and second residual portions 622b and 622c can be left on the lid 620 while the first and second residual portions 622b and 622c are left. Specifically, at the stripped portion 622a of the metal film 622, the strength of the adhesive may be made stronger than at the first and second remaining portions 622b and 622c. Also, if necessary, perforations may be formed at boundaries between the stripped portion 622a and the first and second remaining portions 622b and 622c.
　図３３は、ＲＦＩＤ機能付き容器６００において本体６１０から剥離された蓋６２０の底面図である。蓋６２０を本体６１０から剥離することで、金属膜６２２から剥離部６２２ａが除去される。そのため、剥離部６２２ａの跡には、金属膜６２２を貫通して基材６２１を露出させる貫通部６２３ｂが形成される。貫通部６２３ｂは、剥離部６２２ａに対応する形状である。貫通部６２３ｂは、溝部６２３ａにつながる。これにより、貫通部６２３ｂと溝部６２３ａとがスリット６２３を構成する。スリット６２３により、金属膜６２２は、第１残留部６２２ｂと第２残留部６２２ｃとに分割される。金属膜６２２において、第１残留部６２２ｂと第２残留部６２２ｃとは貫通部６２３ｂにより互いに電気的に分離される。第２残留部６２２ｃは、上述したように溝部６２３ａにおいて分離されている。これによって、第２残留部６２２ｃを、ＲＦＩＤモジュール６３０のためのループアンテナパターンとして用いることができる。以下では、第２残留部６２２ｃをループアンテナパターン６２２ｃということがある。 FIG. 33 is a bottom view of the lid 620 peeled off from the main body 610 in the container 600 with RFID function. By peeling the lid 620 from the main body 610 , the peeled portion 622 a is removed from the metal film 622 . Therefore, a penetrating portion 623b that penetrates the metal film 622 and exposes the base material 621 is formed at the trace of the peeled portion 622a. The penetrating portion 623b has a shape corresponding to the peeling portion 622a. The penetrating portion 623b connects to the groove portion 623a. Thereby, the slit 623 is formed by the penetrating portion 623b and the groove portion 623a. The slit 623 divides the metal film 622 into a first remaining portion 622b and a second remaining portion 622c. In the metal film 622, the first remaining portion 622b and the second remaining portion 622c are electrically separated from each other by the penetrating portion 623b. The second residual portion 622c is separated at the groove portion 623a as described above. This allows the second residual portion 622 c to be used as a loop antenna pattern for the RFID module 630 . Below, the 2nd residual part 622c may be called loop antenna pattern 622c.
　上述したように、ＲＦＩＤモジュール６３０は、蓋６２０において、スリット６２３の溝部６２３ａを跨ぐように金属膜６２２に結合される。蓋６２０を本体６１０から剥離することで、金属膜６２２のループアンテナパターン６２２ｃは、ＲＦＩＤモジュール６３０に対して、ループアンテナとして機能する。これによって、ＲＦＩＤモジュール６３０は、金属膜６２２を利用した通信を行うことが可能となる。そのため、ＲＦＩＤ機能は有効化される。 As described above, the RFID module 630 is coupled to the metal film 622 in the lid 620 so as to straddle the groove 623a of the slit 623 . By peeling off the lid 620 from the main body 610 , the loop antenna pattern 622 c of the metal film 622 functions as a loop antenna for the RFID module 630 . This enables the RFID module 630 to perform communication using the metal film 622 . Therefore, the RFID function is activated.
　［１．６．２　効果等］
　以上述べたように、ＲＦＩＤ機能付き容器６００は、本体６１０と、蓋６２０と、ＲＦＩＤモジュール６３０とを備える。本体６１０は、電気絶縁性を有する。本体６１０は、内容物Ｎ１００用の収容空間６１１を有する。蓋６２０は、金属膜６２２を含み、収容空間６１１の開口を覆うように本体６１０に取り付けられる。ＲＦＩＤモジュール６３０は、収容空間６１１の開口の外側にあるように蓋６２０に取り付けられる。金属膜６２２は、蓋６２０を本体６１０から剥離した際に蓋６２０から剥離されて本体６１０に残る剥離部６２２ａと、蓋６２０を本体６１０から剥離した際に蓋６２０から剥離されずに蓋６２０に残る残留部６２２ｃとを有する。残留部６２２ｃの形状は、剥離部６２２ａにより規定される。残留部６２２ｃは、アンテナ形状を有するアンテナパターンである。ＲＦＩＤモジュール６３０は、第１及び第２電極６３１，６３２を有し、第１及び第２電極６３１，６３２が金属膜６２２の残留部６２２ｃに結合されるように、蓋６２０に配置される。この構成は、蓋６２０が本体６１０に取り付けられた状態ではＲＦＩＤモジュール６３０による通信を無効化し、蓋６２０が本体６１０から剥離されるとＲＦＩＤモジュール６３０による通信を有効化することができる。 [1.6.2 Effects, etc.]
As described above, RFID function-equipped container 600 includes main body 610 , lid 620 , and RFID module 630 . Body 610 is electrically insulating. The main body 610 has an accommodation space 611 for the contents N100. The lid 620 includes a metal film 622 and is attached to the main body 610 so as to cover the opening of the accommodation space 611 . The RFID module 630 is attached to the lid 620 so as to be outside the opening of the containing space 611 . The metal film 622 includes a peeled portion 622a that is peeled off from the lid 620 and remains on the main body 610 when the lid 620 is peeled off from the main body 610, and a peeled portion 622a that is not peeled off from the lid 620 when the lid 620 is peeled off from the main body 610 and is attached to the lid 620. and a residual portion 622c. The shape of the remaining portion 622c is defined by the stripped portion 622a. The remaining portion 622c is an antenna pattern having an antenna shape. The RFID module 630 has first and second electrodes 631 , 632 and is arranged on the lid 620 such that the first and second electrodes 631 , 632 are coupled to the remaining portion 622 c of the metal film 622 . This configuration can disable communication by the RFID module 630 when the lid 620 is attached to the body 610 and enable communication by the RFID module 630 when the lid 620 is peeled off the body 610 .
　ＲＦＩＤ機能付き容器６００において、蓋６２０は、金属膜６２２を貫通する溝部６２３ａを備える。剥離部６２２ａは、蓋６２０を本体６１０から剥離した際に蓋６２０から剥離されると金属膜６２２に溝部６２３ａにつながる貫通部６２３ｂを残す。貫通部６２３ｂと溝部６２３ａとは、残留部６２２ｃのアンテナ形状を規定するスリット６２３を形成する。 In the RFID function-equipped container 600 , the lid 620 has a groove 623 a penetrating the metal film 622 . When the lid 620 is peeled off from the main body 610 , the peeled portion 622 a leaves a penetrating portion 623 b connected to the groove portion 623 a in the metal film 622 . The through portion 623b and the groove portion 623a form a slit 623 that defines the antenna shape of the remaining portion 622c.
　以上述べたＲＦＩＤ機能付き容器６００は、内容物Ｎ１００が使用される前はＲＦＩＤ機能が無効になっており、内容物Ｎ１００が使用された後はＲＦＩＤ機能が有効になるように構成されている。ＲＦＩＤ機能付き容器６００を用いた商品は、店頭で陳列されている状態では、ＲＦＩＤ機能により情報を読み出すことができない。一方で、消費者がＲＦＩＤ機能付き容器６００を用いた商品を購入し、内容物Ｎ１００を使用した後は、ＲＦＩＤ機能により情報が読み出すことができるようになる。つまり、ＲＦＩＤ機能付き容器６００の回収時には、ＲＦＩＤ機能が利用できるようになる。そのため、例えば、ＲＦＩＤ機能付き容器６００を用いた商品の販売促進キャンペーン等で、商品が消費されたかどうかを正しく識別できるから、キャンペーン等での不正を防止できる。特に、内容物Ｎ１００が使用される前はＲＦＩＤ機能が無効になっているから、ＲＦＩＤ機能による情報の漏洩の防止が期待できる。 The RFID function-equipped container 600 described above is configured such that the RFID function is disabled before the content N100 is used, and the RFID function is enabled after the content N100 is used. Information on products using the container 600 with RFID function cannot be read by the RFID function while the product is displayed in a shop. On the other hand, after the consumer purchases the product using the container 600 with RFID function and uses the content N100, the information can be read by the RFID function. That is, when the container 600 with RFID function is collected, the RFID function can be used. Therefore, for example, in a product sales promotion campaign using the container 600 with RFID function, it is possible to correctly identify whether or not the product has been consumed, thereby preventing fraudulent campaigns. In particular, since the RFID function is disabled before the content N100 is used, prevention of information leakage due to the RFID function can be expected.
　［１．６．３　変形例］
　実施の形態６は、上記構成に限定されない。実施の形態６は、その課題を達成できれば、設計等に応じて種々の変更が可能である。以下に、実施の形態６の変形例を列挙する。以下に説明する変形例は、適宜組み合わせて適用可能である。 [1.6.3 Modification]
Embodiment 6 is not limited to the above configuration. Embodiment 6 can be modified in various ways according to the design, etc., as long as the problem can be achieved. Modifications of the sixth embodiment are listed below. Modifications described below can be applied in combination as appropriate.
　［１．６．３．１　変形例１］
　図３４は、実施の形態６の変形例１のＲＦＩＤ機能付き容器の蓋６２０Ａの構成例の底面図である。蓋６２０Ａは、金属膜６２２Ａを含む。 [1.6.3.1 Modification 1]
FIG. 34 is a bottom view of a configuration example of lid 620A of the RFID function-equipped container according to Modification 1 of Embodiment 6. FIG. Lid 620A includes metal film 622A.
　金属膜６２２Ａは、剥離部６２２ｄと、残留部６２２ｅとを有する。剥離部６２２ｄは、金属膜６２２Ａにおいて、蓋６２０Ａを本体６１０から剥離した際に蓋６２０Ａから剥離されて本体６１０に残る部分である。剥離部６２２ｄは、金属膜６２２Ａにおいて本体６１０の収容空間６１１の開口を覆う所定領域Ｒ６００を避けて配置される。剥離部６２２ｄは、Ｌ字形である。剥離部６２２ｄは、金属膜６２２Ａの角部から当該角部を構成する２辺に沿ってそれぞれ直線状に延びる。残留部６２２ｅは、金属膜６２２Ａにおいて、蓋６２０Ａを本体６１０から剥離した際に蓋６２０Ａから剥離されずに残る部分である。残留部６２２ｅは、金属膜６２２Ａにおいて本体６１０の収容空間６１１の開口を覆う所定領域Ｒ６００を含む。残留部６２２ｅには、スリット６２３Ａを構成する溝部６２３ａが形成される。溝部６２３ａは、金属膜６２２Ａの角部にあって、剥離部６２２ｄから金属膜６２２Ａの外方に延びる。残留部６２２ｅにおいて剥離部６２２ｄの周囲の所定部分６２２ｆは、溝部６２３ａにおいて分離されている。これによって、残留部６２２ｅの所定部分６２２ｆは、溝部６２３ａを挟んで対向する第１及び第２端６２２ｆａ，６２２ｆｂを有する。残留部６２２ｅの所定部分６２２ｆは、剥離部６２２ｄが蓋６２０Ａから剥離されることで、アンテナパターンを構成する。特に、残留部６２２ｅの所定部分６２２ｆは、剥離部６２２ｄが蓋６２０Ａから剥離されることで、ループアンテナパターンを構成する。 The metal film 622A has a stripped portion 622d and a remaining portion 622e. The peeled portion 622d is a portion of the metal film 622A that is peeled off from the lid 620A and remains on the main body 610 when the lid 620A is peeled off from the main body 610. FIG. The peeling portion 622d is arranged in the metal film 622A so as to avoid the predetermined region R600 covering the opening of the accommodation space 611 of the main body 610. As shown in FIG. The peeling portion 622d is L-shaped. The peeled portion 622d linearly extends from the corner of the metal film 622A along two sides forming the corner. The remaining portion 622e is a portion of the metal film 622A that remains without being separated from the lid 620A when the lid 620A is separated from the main body 610. FIG. The remaining portion 622e includes a predetermined region R600 that covers the opening of the accommodation space 611 of the main body 610 in the metal film 622A. A groove portion 623a forming a slit 623A is formed in the remaining portion 622e. The groove portion 623a is located at the corner of the metal film 622A and extends outward from the metal film 622A from the peeled portion 622d. A predetermined portion 622f around the peeled portion 622d in the remaining portion 622e is separated by the groove portion 623a. Accordingly, the predetermined portion 622f of the remaining portion 622e has first and second ends 622fa and 622fb facing each other across the groove portion 623a. A predetermined portion 622f of the remaining portion 622e forms an antenna pattern by peeling the peeling portion 622d from the lid 620A. In particular, a predetermined portion 622f of the remaining portion 622e constitutes a loop antenna pattern by peeling the peeling portion 622d from the lid 620A.
　ＲＦＩＤモジュール６３０は、蓋６２０Ａにおいて、スリット６２３Ａの溝部６２３ａを跨ぐように金属膜６２２Ａに結合される。より詳細には、ＲＦＩＤモジュール６３０は、第１及び第２電極６３１，６３２が金属膜６２２Ａの残留部６２２ｅの所定部分６２２ｆの第１端６２２ｆａ及び第２端６２２ｆｂにそれぞれ結合（容量結合）されるように、蓋６２０Ａにある。 The RFID module 630 is coupled to the metal film 622A in the lid 620A so as to straddle the groove 623a of the slit 623A. More specifically, in the RFID module 630, the first and second electrodes 631 and 632 are coupled (capacitively coupled) to the first end 622fa and the second end 622fb of the predetermined portion 622f of the residual portion 622e of the metal film 622A. As such, on lid 620A.
　図３４の蓋６２０Ａでは、金属膜６２２Ａにアンテナパターンが形成されておらず、ＲＦＩＤモジュール６３０は、金属膜６２２Ａを利用した通信を行うことができない。そのため、ＲＦＩＤ機能は無効化されている。 In the lid 620A of FIG. 34, no antenna pattern is formed on the metal film 622A, and the RFID module 630 cannot perform communication using the metal film 622A. Therefore, the RFID function is disabled.
　図３５は、ＲＦＩＤ機能付き容器において本体６１０から剥離された蓋６２０Ａの底面図である。蓋６２０Ａを本体６１０から剥離することで、金属膜６２２Ａから剥離部６２２ｄが除去される。そのため、剥離部６２２ｄの跡には、金属膜６２２Ａを貫通して基材６２１を露出させる貫通部６２３ｃが形成される。貫通部６２３ｃは、剥離部６２２ｄに対応する形状である。貫通部６２３ｃは、溝部６２３ａにつながる。これにより、貫通部６２３ｃと溝部６２３ａとがスリット６２３Ａを構成する。スリット６２３Ａにより、残留部６２２ｅの所定部分６２２ｆが、ループアンテナとして機能するようになる。以下では、所定部分６２２ｆをループアンテナパターン６２２ｆということがある。 FIG. 35 is a bottom view of the lid 620A separated from the main body 610 in the container with RFID function. By peeling the lid 620A from the main body 610, the peeled portion 622d is removed from the metal film 622A. Therefore, a penetrating portion 623c that penetrates the metal film 622A and exposes the base material 621 is formed at the trace of the peeled portion 622d. The penetrating portion 623c has a shape corresponding to the peeling portion 622d. The through portion 623c connects to the groove portion 623a. Thereby, the through portion 623c and the groove portion 623a constitute the slit 623A. The slit 623A allows the predetermined portion 622f of the residual portion 622e to function as a loop antenna. Below, 622 f of predetermined parts may be called loop antenna pattern 622f.
　蓋６２０Ａを本体６１０から剥離することで、金属膜６２２Ａのループアンテナパターン６２２ｆは、ＲＦＩＤモジュール６３０に対して、ループアンテナとして機能する。これによって、ＲＦＩＤモジュール６３０は、金属膜６２２Ａを利用した通信を行うことが可能となる。そのため、ＲＦＩＤ機能は有効化される。 By peeling off the lid 620A from the main body 610, the loop antenna pattern 622f of the metal film 622A functions as a loop antenna for the RFID module 630. This enables the RFID module 630 to perform communication using the metal film 622A. Therefore, the RFID function is activated.
　［１．６．３．２　変形例２］
　図３６は、実施の形態６の変形例２のＲＦＩＤ機能付き容器の蓋６２０Ｂの構成例の底面図である。蓋６２０Ｂは、金属膜６２２Ｂを含む。 [1.6.3.2 Modification 2]
FIG. 36 is a bottom view of a configuration example of a container lid 620B with an RFID function according to Modification 2 of Embodiment 6. FIG. Lid 620B includes metal film 622B.
　金属膜６２２Ｂは、剥離部６２２ｇと、残留部６２２ｈとを有する。剥離部６２２ｇは、金属膜６２２Ｂにおいて、蓋６２０Ｂを本体６１０から剥離した際に蓋６２０Ｂから剥離されて本体６１０に残る部分である。剥離部６２２ｇは、金属膜６２２Ｂにおいて本体６１０の収容空間６１１の開口を覆う所定領域Ｒ６００を避けて配置される。剥離部６２２ｇは、直線形である。剥離部６２２ｇは、金属膜６２２Ｂの角部から当該角部を構成する２辺の一方に沿って延びる。図３６では、剥離部６２２ｇは左右方向に延びる。残留部６２２ｈは、金属膜６２２Ｂにおいて、蓋６２０Ｂを本体６１０から剥離した際に蓋６２０Ｂから剥離されずに残る部分である。残留部６２２ｈは、金属膜６２２Ｂにおいて本体６１０の収容空間６１１の開口を覆う所定領域Ｒ６００を含む。残留部６２２ｈには、スリット６２３Ｂを構成する溝部６２３ａが形成される。溝部６２３ａは、金属膜６２２Ｂの角部にあって、剥離部６２２ｇの一端から金属膜６２２Ｂの外方に延びる。残留部６２２ｈにおいて剥離部６２２ｇの周囲の所定部分６２２ｉは、溝部６２３ａにおいて分離されている。これによって、残留部６２２ｈの所定部分６２２ｉは、溝部６２３ａを挟んで対向する第１及び第２端６２２ｉａ，６２２ｉｂを有する。残留部６２２ｈの所定部分６２２ｉは、剥離部６２２ｇが蓋６２０Ｂから剥離されることで、ループアンテナパターンを構成する。 The metal film 622B has a stripped portion 622g and a remaining portion 622h. The peeled portion 622g is a portion of the metal film 622B that is peeled from the lid 620B and remains on the main body 610 when the lid 620B is peeled off from the main body 610. FIG. The peeled portion 622g is arranged in the metal film 622B so as to avoid the predetermined region R600 covering the opening of the housing space 611 of the main body 610. As shown in FIG. The stripped portion 622g is linear. The peeled portion 622g extends from the corner of the metal film 622B along one of the two sides forming the corner. In FIG. 36, the stripped portion 622g extends in the left-right direction. The remaining portion 622h is a portion of the metal film 622B that remains without being separated from the lid 620B when the lid 620B is separated from the main body 610. FIG. The remaining portion 622h includes a predetermined region R600 that covers the opening of the accommodation space 611 of the main body 610 in the metal film 622B. A groove portion 623a forming a slit 623B is formed in the remaining portion 622h. The groove 623a is located at the corner of the metal film 622B and extends outward from the metal film 622B from one end of the stripped portion 622g. A predetermined portion 622i around the peeled portion 622g in the residual portion 622h is separated by a groove portion 623a. Thus, the predetermined portion 622i of the remaining portion 622h has first and second ends 622ia and 622ib facing each other with the groove portion 623a interposed therebetween. A predetermined portion 622i of the remaining portion 622h forms a loop antenna pattern by peeling the peeling portion 622g from the lid 620B.
　ＲＦＩＤモジュール６３０は、蓋６２０Ｂにおいて、スリット６２３Ｂの溝部６２３ａを跨ぐように金属膜６２２Ｂに結合される。より詳細には、ＲＦＩＤモジュール６３０は、第１及び第２電極６３１，６３２が金属膜６２２Ｂの残留部６２２ｈの所定部分６２２ｉの第１端６２２ｉａ及び第２端６２２ｉｂにそれぞれ結合（容量結合）されるように、蓋６２０Ｂにある。 The RFID module 630 is coupled to the metal film 622B in the lid 620B so as to straddle the groove 623a of the slit 623B. More specifically, in the RFID module 630, the first and second electrodes 631, 632 are coupled (capacitively coupled) to the first end 622ia and the second end 622ib of the predetermined portion 622i of the remaining portion 622h of the metal film 622B. As such, on lid 620B.
　図３６の蓋６２０Ｂでは、金属膜６２２Ｂにアンテナパターンが形成されておらず、ＲＦＩＤモジュール６３０は、金属膜６２２Ｂを利用した通信を行うことができない。そのため、ＲＦＩＤ機能は無効化されている。 In the lid 620B of FIG. 36, no antenna pattern is formed on the metal film 622B, and the RFID module 630 cannot perform communication using the metal film 622B. Therefore, the RFID function is disabled.
　図３７は、ＲＦＩＤ機能付き容器において本体６１０から剥離された蓋６２０Ｂの底面図である。蓋６２０ｂを本体６１０から剥離することで、金属膜６２２Ｂから剥離部６２２ｇが除去される。そのため、剥離部６２２ｇの跡には、金属膜６２２Ｂを貫通して基材６２１を露出させる貫通部６２３ｅが形成される。貫通部６２３ｅは、剥離部６２２ｇに対応する形状である。貫通部６２３ｅは、溝部６２３ａにつながる。これにより、貫通部６２３ｅと溝部６２３ａとがスリット６２３Ｂを構成する。スリット６２３Ｂにより、残留部６２２ｈの所定部分６２２ｉが、ループアンテナとして機能するようになる。以下では、所定部分６２２ｉをループアンテナパターン６２２ｉということがある。 FIG. 37 is a bottom view of the lid 620B separated from the main body 610 in the container with RFID function. By peeling the lid 620b from the main body 610, the peeled portion 622g is removed from the metal film 622B. Therefore, a penetrating portion 623e that penetrates the metal film 622B and exposes the base material 621 is formed at the trace of the peeled portion 622g. The penetrating portion 623e has a shape corresponding to the peeling portion 622g. The penetrating portion 623e connects to the groove portion 623a. Thereby, the through portion 623e and the groove portion 623a constitute the slit 623B. The slit 623B allows the predetermined portion 622i of the residual portion 622h to function as a loop antenna. Below, the predetermined portion 622i may be referred to as a loop antenna pattern 622i.
　蓋６２０Ｂを本体６１０から剥離することで、金属膜６２２Ｂのループアンテナパターン６２２ｉは、ＲＦＩＤモジュール６３０に対して、ループアンテナとして機能する。これによって、ＲＦＩＤモジュール６３０は、金属膜６２２Ｂを利用した通信を行うことが可能となる。そのため、ＲＦＩＤ機能は有効化される。 By peeling off the lid 620B from the main body 610, the loop antenna pattern 622i of the metal film 622B functions as a loop antenna for the RFID module 630. This enables the RFID module 630 to perform communication using the metal film 622B. Therefore, the RFID function is activated.
　［１．６．３．３　その他の変形例］
　一変形例では、金属膜の残留部の所定部分は、剥離部が蓋から剥離されることで、ループアンテナパターンではなくダイポールアンテナパターンを構成してよい。つまり、金属膜に形成されるアンテナパターンとしては、実施の形態１及び実施の形態２で述べたような種々のアンテナパターンを適用できる。 [1.6.3.3 Other modified examples]
In one variation, a predetermined portion of the remaining portion of the metal film may form a dipole antenna pattern rather than a loop antenna pattern by peeling the peeling portion from the lid. That is, various antenna patterns as described in the first and second embodiments can be applied as the antenna pattern formed on the metal film.
　［１．７　実施の形態７］
　［１．７．１　構成］
　図３８は、実施の形態７のＲＦＩＤ機能付き容器７００の構成例の斜視図である。図３８のＲＦＩＤ機能付き容器７００は、本体７１０と、蓋７２０と、ＲＦＩＤモジュール７３０とを備える。 [1.7 Embodiment 7]
[1.7.1 Configuration]
FIG. 38 is a perspective view of a configuration example of an RFID function-equipped container 700 according to the seventh embodiment. The RFID function-equipped container 700 of FIG. 38 includes a main body 710 , a lid 720 and an RFID module 730 .
　図３９は、蓋７２０の構成例の底面図である。図４０は、ＲＦＩＤ機能付き容器７００において蓋７２０を本体７１０から剥離した状態を示す斜視図である。 39 is a bottom view of a configuration example of the lid 720. FIG. FIG. 40 is a perspective view showing a state in which the lid 720 is peeled off from the main body 710 in the container 700 with RFID function.
　図４０に示すように、本体７１０は、内容物Ｎ１００用の収容空間７１１を有する。本体７１０は、電気絶縁性を有する。本体７１０は、例えば、紙、樹脂材料、又はガラス等の誘電体材料から形成される。樹脂材料は、例えば、発泡スチロールを含む。本体７１０は、有底の筒状部７１２と、フランジ部７１３とを有する。筒状部７１２は、収容空間７１１を規定する。筒状部７１２は、円筒形状である。フランジ部７１３は、収容空間７１１の開口縁部から外方に突出する。フランジ部７１３の外形形状は、正方形状である。 As shown in FIG. 40, the main body 710 has an accommodation space 711 for the contents N100. Body 710 is electrically insulating. The main body 710 is made of dielectric material such as paper, resin material, or glass, for example. The resin material includes expanded polystyrene, for example. The main body 710 has a bottomed tubular portion 712 and a flange portion 713 . The tubular portion 712 defines a housing space 711 . The cylindrical portion 712 has a cylindrical shape. The flange portion 713 protrudes outward from the opening edge of the housing space 711 . The outer shape of the flange portion 713 is square.
　図３８に示すように、蓋７２０は、本体７１０に、収容空間７１１の開口を覆うように取り付けられる。図３８の蓋７２０は、剥離可能に本体７２１０に取り付けられる。蓋７２０は、本体７１０の収容空間７１１から内容物Ｎ１００を取り出す際に、本体７１０から剥離される。蓋７２０は全体的に可撓性を有する。蓋７２０は、基材７２１と、金属膜７２２とを含む。基材７２１は、収容空間７１１の開口を覆う。特に、基材７２１は、収容空間７１１の開口及びフランジ部７１３を全体的に覆う。基材７２１の外形形状は、正方形状である。基材７２１は、例えば、紙又はプラスチック等の誘電体材料から形成される。金属膜７２２は、本体７１０の収容空間７１１の開口を覆う。金属膜７２２は、収容空間７１１の開口及びフランジ部７１３を全体的に覆う。金属膜７２２は、基材７２１における本体７１０側の面にある。金属膜７２２は、外部要因に起因する内容物の変化を防止する作用を有し得る。このように、金属膜７２２は、収容空間７１１の開口を覆うことで、内容物Ｎ１００を保護する。金属膜７２２の材料としては、アルミニウム及びアルミニウムを含む合金が挙げられる。蓋７２０は、接着剤により本体７１０の収容空間７１１の開口の周縁部分に取り付けられる。図３９では、蓋７２０は、本体７１０のフランジ部７１３に接着剤で取り付けられる。接着剤は、蓋７２０においてフランジ部７１３に対向する領域に塗布される。 As shown in FIG. 38 , the lid 720 is attached to the main body 710 so as to cover the opening of the housing space 711 . Lid 720 in FIG. 38 is releasably attached to body 7210 . The lid 720 is peeled off from the main body 710 when the content N100 is taken out from the housing space 711 of the main body 710 . Lid 720 is generally flexible. Lid 720 includes base material 721 and metal film 722 . The base material 721 covers the opening of the accommodation space 711 . In particular, the base material 721 entirely covers the opening of the housing space 711 and the flange portion 713 . The outer shape of the base material 721 is square. Substrate 721 is formed, for example, from a dielectric material such as paper or plastic. The metal film 722 covers the opening of the accommodation space 711 of the main body 710 . The metal film 722 entirely covers the opening of the housing space 711 and the flange portion 713 . The metal film 722 is on the surface of the base material 721 on the main body 710 side. The metal film 722 can act to prevent changes in the contents due to external factors. Thus, the metal film 722 protects the content N100 by covering the opening of the accommodation space 711. FIG. Materials for the metal film 722 include aluminum and alloys containing aluminum. The lid 720 is attached to the periphery of the opening of the accommodation space 711 of the main body 710 with an adhesive. In FIG. 39, the lid 720 is adhesively attached to the flange portion 713 of the body 710 . The adhesive is applied to a region of lid 720 facing flange portion 713 .
　図３９に示すように、金属膜７２２には、スリット７２３が形成される。スリット７２３は、金属膜７２２において本体７１０の収容空間７１１の開口を覆う所定領域Ｒ７００を避けて配置される。スリット７２３は、溝部７２３ａと、枠部７２３ｂとを含む。枠部７２３ｂは、所定領域Ｒ７００を囲う円環状である。枠部７２３ｂの外形形状は所定領域Ｒ７００と同心円である。溝部７２３ａは、枠部７２３ｂから蓋７２０の外方に延びている。 As shown in FIG. 39, slits 723 are formed in the metal film 722 . The slit 723 is arranged in the metal film 722 so as to avoid the predetermined region R700 covering the opening of the housing space 711 of the main body 710 . The slit 723 includes a groove portion 723a and a frame portion 723b. The frame portion 723b has an annular shape surrounding the predetermined region R700. The outer shape of the frame portion 723b is concentric with the predetermined region R700. The groove portion 723a extends outward from the lid 720 from the frame portion 723b.
　スリット７２３により、金属膜７２２は、収容空間７１１の開口を覆う中央部７２２ａと、中央部７２２ａを囲う周辺部７２２ｂとに分割される。中央部７２２ａは、金属膜７２２において収容空間７１１の開口を覆う所定領域Ｒ７００を含む。周辺部７２２ｂは、中央部７２２ａを囲う形状であるが、溝部７２３ａにおいて分離されている。これによって、周辺部７２２ｂは、溝部７２３ａを挟んで対向する第１及び第２端７２２ｂａ，７２２ｂｂと、第１及び第２端７２２ｂａ，７２２ｂｂを連結する連結部７２２ｂｃとを有する。周辺部７２２ｂは、アンテナ形状を有するアンテナパターンである。本実施の形態では、周辺部７２２ｂは、ＲＦＩＤモジュール７３０のためのループアンテナパターンとして用いることができる。以下では、周辺部７２２ｂをアンテナパターン７２２ｂということがある。 The slit 723 divides the metal film 722 into a central portion 722a that covers the opening of the housing space 711 and a peripheral portion 722b that surrounds the central portion 722a. The center portion 722 a includes a predetermined region R 700 covering the opening of the accommodation space 711 in the metal film 722 . The peripheral portion 722b has a shape surrounding the central portion 722a, but is separated by the groove portion 723a. Thus, the peripheral portion 722b has first and second ends 722ba and 722bb facing each other across the groove portion 723a, and a connecting portion 722bc connecting the first and second ends 722ba and 722bb. The peripheral portion 722b is an antenna pattern having an antenna shape. In this embodiment, perimeter 722b can be used as a loop antenna pattern for RFID module 730. FIG. Below, the peripheral portion 722b may be referred to as an antenna pattern 722b.
　ＲＦＩＤモジュール７３０は、蓋７２０において、スリット７２３の溝部７２３ａを跨ぐように金属膜７２２に結合される。より詳細には、ＲＦＩＤモジュール７３０は、第１及び第２電極７３１，７３２がアンテナパターン７２２ｂの第１端７２２ｂａ及び第２端７２２ｂｂにそれぞれ結合（容量結合）されるように、蓋７２０にある。 The RFID module 730 is coupled to the metal film 722 in the lid 720 so as to straddle the groove 723a of the slit 723 . More specifically, the RFID module 730 is on the lid 720 such that the first and second electrodes 731, 732 are coupled (capacitively coupled) to the first end 722ba and the second end 722bb of the antenna pattern 722b, respectively.
　図３９の蓋７２０では、金属膜７２２にアンテナパターン７２２ｂが形成されているから、ＲＦＩＤモジュール７３０は、金属膜７２２を利用した通信を行うことができる。そのため、ＲＦＩＤ機能は有効化されている。 In the lid 720 of FIG. 39, the antenna pattern 722b is formed on the metal film 722, so the RFID module 730 can perform communication using the metal film 722. Therefore, the RFID function is activated.
　図３９に示すように、金属膜７２２は、剥離部（第１及び第２剥離部）７２２ｃ，７２２ｄを有する。第１及び第２剥離部７２２ｃ，７２２ｄは、金属膜７２２において、蓋７２０を本体７１０から剥離した際に蓋７２０から剥離されて本体７１０に残る部分である。金属膜７２２における第１及び第２剥離部７２２ｃ，７２２ｄ以外の部位は、蓋７２０に残留する。第１及び第２剥離部７２２ｃ，７２２ｄは、金属膜７２２のアンテナパターン７２２ｂの一部である。第１及び第２剥離部７２２ｃ，７２２ｄは、剥離されることで、アンテナパターン７２２ｂが破損して、ＲＦＩＤモジュール７３０に対して、アンテナとして機能しなくなるように形成される。第１剥離部７２２ｃは、スリット７２３の溝部７２３ａから溝部７２３ａと交差する方向に金属膜７２２の外方に延びる。第１剥離部７２２ｃが剥離されることで、アンテナパターン７２２ｂの第１端７２２ｂａと連結部７２２ｂｃとが電気的に分離される。第２剥離部７２２ｄは、スリット７２３の溝部７２３ａから溝部７２３ａと交差し、第１剥離部７２２ｃとは反対の方向に、金属膜７２２の外方に延びる。第２剥離部７２２ｄが剥離されることで、アンテナパターン７２２ｂの第２端７２２ｂｂと連結部７２２ｂｃとが電気的に分離される。 As shown in FIG. 39, the metal film 722 has peeled portions (first and second peeled portions) 722c and 722d. The first and second peeling portions 722 c and 722 d are portions of the metal film 722 that are peeled off from the lid 720 and remain on the main body 710 when the lid 720 is peeled off from the main body 710 . Portions of the metal film 722 other than the first and second peeled portions 722 c and 722 d remain on the lid 720 . The first and second stripped portions 722 c and 722 d are part of the antenna pattern 722 b of the metal film 722 . The first and second peeling portions 722 c and 722 d are formed so that the antenna pattern 722 b is damaged by being peeled and does not function as an antenna for the RFID module 730 . The first peeling portion 722c extends outward from the metal film 722 from the groove portion 723a of the slit 723 in a direction crossing the groove portion 723a. By peeling the first peeling portion 722c, the first end 722ba of the antenna pattern 722b and the connecting portion 722bc are electrically separated. The second peeling portion 722d intersects with the groove portion 723a from the groove portion 723a of the slit 723 and extends outward from the metal film 722 in the direction opposite to the first peeling portion 722c. By peeling the second peeling portion 722d, the second end 722bb of the antenna pattern 722b and the connecting portion 722bc are electrically separated.
　図４０に示すように、金属膜７２２において、第１及び第２剥離部７２２ｃ，７２２ｄは、蓋７２０を本体７１０から剥離する際に本体７１０に残留することで蓋７２０から除去される。金属膜７２２における第１及び第２剥離部７２２ｃ，７２２ｄ以外の部位は、蓋７２０を本体７１０から剥離しても蓋７２０に残留する。 As shown in FIG. 40 , in the metal film 722 , the first and second peeling portions 722 c and 722 d are removed from the lid 720 by remaining on the main body 710 when the lid 720 is peeled off from the main body 710 . Parts of the metal film 722 other than the first and second peeling portions 722 c and 722 d remain on the lid 720 even if the lid 720 is peeled off from the main body 710 .
　図４１は、ＲＦＩＤ機能付き容器７００において本体７１０から剥離された蓋７２０の底面図である。図４１に示すように、金属膜７２２は、蓋７２０を本体７１０から剥離する際に選択的に除去される。例えば、金属膜７２２の第１及び第２剥離部７２２ｃ，７２２ｄと金属膜７２２における第１及び第２剥離部７２２ｃ，７２２ｄ以外の部位とで、蓋７２０と本体７１０との間の接着剤の強度を異ならせることで、第１及び第２剥離部７２２ｃ，７２２ｄだけを蓋７２０から剥離させて本体７１０に残すことができる。具体的には、金属膜７２２の第１及び第２剥離部７２２ｃ，７２２ｄでの接着剤の強度を金属膜７２２における第１及び第２剥離部７２２ｃ，７２２ｄ以外の部位での接着剤の強度より強くすればよい。また、必要に応じて、第１剥離部７２２ｃ，７２２ｄとそれ以外の部位との境界にミシン目を形成してもよい。 FIG. 41 is a bottom view of the lid 720 peeled off from the main body 710 in the container 700 with RFID function. As shown in FIG. 41, metal film 722 is selectively removed when peeling lid 720 from body 710 . For example, the strength of the adhesive between the lid 720 and the main body 710 is determined by the first and second peeling portions 722c and 722d of the metal film 722 and the portions of the metal film 722 other than the first and second peeling portions 722c and 722d. are different, only the first and second peeling portions 722 c and 722 d can be peeled off from the lid 720 and left on the main body 710 . Specifically, the strength of the adhesive at the first and second peeled portions 722c and 722d of the metal film 722 is more than the strength of the adhesive at portions of the metal film 722 other than the first and second peeled portions 722c and 722d. It should be strong. Also, if necessary, perforations may be formed at boundaries between the first peeling portions 722c and 722d and other portions.
　蓋７２０を本体７１０から剥離することで、金属膜７２２から第１及び第２剥離部７２２ｃ，７２２ｄが除去される。そのため、第１及び第２剥離部７２２ｃ，７２２ｄの跡には、金属膜７２２を貫通して基材７２１を露出させる第１及び第２貫通部７２３ｃ，７２３ｄが形成される。第１及び第２貫通部７２３ｃ，７２３ｄは、第１及び第２剥離部７２２ｃ，７２２ｄにそれぞれ対応する形状である。第１及び第２貫通部７２３ｃ，７２３ｄは、溝部７２３ａにつながる。これにより、第１及び第２貫通部７２３ｃ，７２３ｄと溝部７２３ａと枠部７２３ｂとがスリット７２３を構成する。スリット７２３により、金属膜７２２のループアンテナパターン７２２ｂが破損して、ＲＦＩＤモジュール７３０に対して、ループアンテナとして機能しなくなる。これによって、ＲＦＩＤモジュール７３０は、金属膜７２２を利用した通信を行うことができなくなる。そのため、ＲＦＩＤ機能が無効化される。 By peeling the lid 720 from the main body 710, the first and second peeling portions 722c and 722d are removed from the metal film 722. Therefore, first and second penetrating portions 723c and 723d that penetrate the metal film 722 and expose the substrate 721 are formed at the traces of the first and second peeling portions 722c and 722d. The first and second penetrating portions 723c, 723d have shapes corresponding to the first and second peeling portions 722c, 722d, respectively. The first and second penetrating portions 723c and 723d are connected to the groove portion 723a. Thereby, the first and second through portions 723c and 723d, the groove portion 723a and the frame portion 723b constitute the slit 723. As shown in FIG. Due to the slit 723 , the loop antenna pattern 722 b of the metal film 722 is damaged and does not function as a loop antenna for the RFID module 730 . As a result, the RFID module 730 cannot perform communication using the metal film 722 . Therefore, the RFID function is disabled.
　［１．７．２　効果等］
　以上述べたように、ＲＦＩＤ機能付き容器７００は、本体７１０と、蓋７２０と、ＲＦＩＤモジュール７３０とを備える。本体７１０は、電気絶縁性を有する。本体７１０は、内容物Ｎ１００用の収容空間７１１を有する。蓋７２０は、金属膜７２２を含み、収容空間７１１の開口を覆うように本体７１０に取り付けられる。ＲＦＩＤモジュール７３０は、収容空間７１１の開口の外側にあるように蓋７２０に取り付けられる。金属膜７２２は、アンテナ形状を有するアンテナパターン７２２ｂを含む。ＲＦＩＤモジュール７３０は、第１及び第２電極７３１，７３２を有し、第１及び第２電極７３１，７３２がアンテナパターン７２２ｂに結合されるように、蓋７２０に配置される。金属膜７２２は、アンテナパターン７２２ｂの一部に、蓋７２０を本体７１０から剥離した際に蓋７２０から剥離されてアンテナパターン７２２ｂを破損する剥離部７２２ｃ，７２２ｄを含む。この構成は、蓋７２０が本体７１０に取り付けられた状態ではＲＦＩＤモジュール７３０による通信を有効化し、蓋７２０が本体７１０から剥離されるとＲＦＩＤモジュール７３０による通信を無効化することができる。 [1.7.2 Effects, etc.]
As described above, RFID function-equipped container 700 includes main body 710 , lid 720 , and RFID module 730 . Body 710 is electrically insulating. The main body 710 has an accommodation space 711 for the contents N100. The lid 720 includes a metal film 722 and is attached to the main body 710 so as to cover the opening of the accommodation space 711 . The RFID module 730 is attached to the lid 720 so as to be outside the opening of the containing space 711 . The metal film 722 includes an antenna pattern 722b having an antenna shape. The RFID module 730 has first and second electrodes 731, 732 and is arranged on the lid 720 such that the first and second electrodes 731, 732 are coupled to the antenna pattern 722b. The metal film 722 includes peeling portions 722c and 722d that are peeled off from the lid 720 and damage the antenna pattern 722b when the lid 720 is peeled off from the main body 710 in a part of the antenna pattern 722b. This configuration can enable communication by the RFID module 730 when the lid 720 is attached to the body 710 and disable communication by the RFID module 730 when the lid 720 is peeled off the body 710 .
　ＲＦＩＤ機能付き容器７００において、剥離部７２２ｃ，７２２ｄは、蓋７２０を本体７１０から剥離した際に蓋７２０から剥離されるとＲＦＩＤモジュール７３０からアンテナパターン７２２ｂを電気的に分離するように形成される。 In the RFID function-equipped container 700 , the peeling parts 722 c and 722 d are formed so as to electrically separate the antenna pattern 722 b from the RFID module 730 when the lid 720 is peeled off from the main body 710 .
　ＲＦＩＤ機能付き容器７００において、アンテナパターン７２２ｂは、ＲＦＩＤモジュール７３０の第１及び第２電極７３１，７３２に結合される第１及び第２端７２２ｂａ，７２２ｂｂを有する。剥離部７２２ｃ，７２２ｄは、蓋７２０を本体７１０から剥離した際に蓋７２０から剥離されるとアンテナパターン７２２ｂの第１端７２２ｂａ及び第２端７２２ｂｂをアンテナパターン７２２ｂの残りの部位から電気的に分離するように形成される。 In the container 700 with RFID function, the antenna pattern 722b has first and second ends 722ba, 722bb coupled to the first and second electrodes 731, 732 of the RFID module 730. The peeling portions 722c and 722d electrically separate the first end 722ba and the second end 722bb of the antenna pattern 722b from the rest of the antenna pattern 722b when the lid 720 is peeled off from the main body 710. is formed to
　ＲＦＩＤ機能付き容器７００において、アンテナパターン７２２ｂは、第１端７２２ｂａ及び第２端７２２ｂｂを連結する連結部７２２ｂｃを有するループアンテナパターンである。剥離部７２２ｃ，７２２ｄは、アンテナパターン７２２ｂの第１端７２２ｂａ及び第２端７２２ｂｂと連結部７２２ｂｃとの間にそれぞれ形成される。 In the RFID function-equipped container 700, the antenna pattern 722b is a loop antenna pattern having a connection portion 722bc that connects the first end 722ba and the second end 722bb. The peeling portions 722c and 722d are respectively formed between the first end 722ba and the second end 722bb of the antenna pattern 722b and the connecting portion 722bc.
　以上述べたＲＦＩＤ機能付き容器７００は、内容物Ｎ１００が使用される前はＲＦＩＤ機能が有効になっており、内容物Ｎ１００が使用された後はＲＦＩＤ機能が無効になるように構成されている。例えば、ＲＦＩＤ機能付き容器７００を用いた商品は、販売前までは、無線通信によって商品を識別及び管理の対象となる。一方で、消費者がＲＦＩＤ機能付き容器７００を用いた商品を購入し、内容物Ｎ１００を使用した後は、ＲＦＩＤ機能により情報が読み出すことができなくなる。つまり、ＲＦＩＤ機能付き容器７００の販売後には、ＲＦＩＤ機能が利用できるようになる。そのため、例えば、ＲＦＩＤ機能付き容器７００を用いた商品の販売までは、商品の識別及び管理が可能であるが、販売後はＲＦＩＤ機能による情報の漏洩の防止が期待できる。 The RFID function-equipped container 700 described above is configured such that the RFID function is enabled before the content N100 is used, and the RFID function is disabled after the content N100 is used. For example, products using the RFID function-equipped container 700 are subject to product identification and management through wireless communication before they are sold. On the other hand, after the consumer purchases the product using the container 700 with RFID function and uses the content N100, the information cannot be read by the RFID function. In other words, after the container 700 with RFID function is sold, the RFID function can be used. Therefore, for example, until the product is sold using the RFID-equipped container 700, it is possible to identify and manage the product.
　［１．７．３　変形例］
　実施の形態７は、上記構成に限定されない。実施の形態７は、その課題を達成できれば、設計等に応じて種々の変更が可能である。図４２は、実施の形態７の一変形例のＲＦＩＤ機能付き容器の蓋７２０Ａの構成例の底面図である。蓋７２０Ａは、スリット７２３Ａが形成された金属膜７２２Ａを含む。 [1.7.3 Modification]
Embodiment 7 is not limited to the above configuration. Embodiment 7 can be modified in various ways according to the design, etc., as long as the problem can be achieved. FIG. 42 is a bottom view of a configuration example of a container lid 720A with an RFID function according to a modification of the seventh embodiment. The lid 720A includes a metal film 722A with slits 723A formed therein.
　スリット７２３Ａは、金属膜７２２Ａにおいて本体７１０の収容空間７１１の開口を覆う所定領域Ｒ７００を避けて配置される。スリット７２３Ａは、溝部７２３ａと、枠部７２３ｂとを含む。スリット７２３Ａにより、金属膜７２２Ａは、収容空間７１１の開口を覆う中央部７２２ａと、中央部７２２ａを囲う周辺部７２２ｂとに分割される。周辺部７２２ｂは、溝部７２３ａを挟んで対向する第１及び第２端７２２ｂａ，７２２ｂｂと、第１及び第２端７２２ｂａ，７２２ｂｂを連結する連結部７２２ｂｃとを有する。周辺部７２２ｂは、ＲＦＩＤモジュール７３０のためのループアンテナパターンとして用いることができる。図４２の蓋７２Ａ０では、金属膜７２２Ａにアンテナパターンが形成されているから、ＲＦＩＤモジュール７３０は、金属膜７２２Ａを利用した通信を行うことができる。そのため、ＲＦＩＤ機能は有効化されている。 The slit 723A is arranged in the metal film 722A so as to avoid the predetermined region R700 covering the opening of the accommodation space 711 of the main body 710. The slit 723A includes a groove portion 723a and a frame portion 723b. The slit 723A divides the metal film 722A into a central portion 722a covering the opening of the housing space 711 and a peripheral portion 722b surrounding the central portion 722a. The peripheral portion 722b has first and second ends 722ba and 722bb facing each other across the groove portion 723a, and a connecting portion 722bc connecting the first and second ends 722ba and 722bb. Periphery 722 b can be used as a loop antenna pattern for RFID module 730 . In the lid 72A0 of FIG. 42, since the antenna pattern is formed on the metal film 722A, the RFID module 730 can perform communication using the metal film 722A. Therefore, the RFID function is activated.
　金属膜７２２Ａは、第１及び第２剥離部７２２ｅ，７２２ｆを有する。第１及び第２剥離部７２２ｅ，７２２ｆは、金属膜７２２Ａにおいて、蓋７２０Ａを本体７１０から剥離した際に蓋７２０Ａから剥離されて本体７１０に残る部分である。金属膜７２２Ａにおける第１及び第２剥離部７２２ｅ，７２２ｆ以外の部位は、蓋７２０Ａに残留する。第１及び第２剥離部７２２ｅ，７２２ｆは、金属膜７２２Ａのアンテナパターン７２２ｂの一部である。第１及び第２剥離部７２２ｃ，７２２ｄは、剥離されることで、アンテナパターン７２２ｂが破損して、ＲＦＩＤモジュール７３０に対して、ループアンテナとして機能できなくなるように形成される。第１剥離部７２２ｅは、スリット７２３Ａの枠部７２３ｂから、溝部７２３ａと第１剥離部７２２ｅとの間にＲＦＩＤモジュール７３０の第１電極７３１が位置するように、金属膜７２２Ａの外方に延びる。第１剥離部７２２ｅが剥離されることで、アンテナパターン７２２ｂの第１端７２２ｂａと連結部７２２ｂｃとが電気的に分離される。第２剥離部７２２ｆは、スリット７２３Ａの枠部７２３ｂから、溝部７２３ａと第２剥離部７２２ｆとの間にＲＦＩＤモジュール７３０の第２電極７３２が位置するように、金属膜７２２Ａの外方に延びる。第２剥離部７２２ｆが剥離されることで、アンテナパターン７２２ｂの第２端７２２ｂｂと連結部７２２ｂｃとが電気的に分離される。 The metal film 722A has first and second peeled portions 722e and 722f. The first and second peeling portions 722e and 722f are portions of the metal film 722A that are peeled off from the lid 720A and remain on the main body 710 when the lid 720A is peeled off from the main body 710. FIG. Parts of the metal film 722A other than the first and second peeled portions 722e and 722f remain on the lid 720A. The first and second stripped portions 722e and 722f are part of the antenna pattern 722b of the metal film 722A. The first and second peeling portions 722 c and 722 d are formed so that the antenna pattern 722 b is damaged by being peeled and cannot function as a loop antenna for the RFID module 730 . The first peeling portion 722e extends outward from the metal film 722A from the frame portion 723b of the slit 723A so that the first electrode 731 of the RFID module 730 is positioned between the groove portion 723a and the first peeling portion 722e. By peeling the first peeling portion 722e, the first end 722ba of the antenna pattern 722b and the connecting portion 722bc are electrically separated. The second peeling portion 722f extends outward from the metal film 722A from the frame portion 723b of the slit 723A so that the second electrode 732 of the RFID module 730 is positioned between the groove portion 723a and the second peeling portion 722f. By peeling the second peeling portion 722f, the second end 722bb of the antenna pattern 722b and the connecting portion 722bc are electrically separated.
　金属膜７２２Ａにおいて、第１及び第２剥離部７２２ｅ，７２２ｆは、蓋７２０Ａを本体７１０から剥離する際に本体７１０に残留することで蓋７２０Ａから除去される。金属膜７２２Ａにおける第１及び第２剥離部７２２ｅ，７２２ｆ以外の部位は、蓋７２０Ａを本体７１０から剥離しても蓋７２０Ａに残留する。 In the metal film 722A, the first and second peeling portions 722e and 722f are removed from the lid 720A by remaining on the main body 710 when the lid 720A is peeled off from the main body 710. Parts of the metal film 722A other than the first and second peeling portions 722e and 722f remain on the lid 720A even when the lid 720A is peeled off from the main body 710. FIG.
　図４３は、本体７１０から剥離された蓋７２０Ａの底面図である。蓋７２０Ａを本体７１０から剥離することで、金属膜７２２Ａから第１及び第２剥離部７２２ｅ，７２２ｆが除去される。そのため、第１及び第２剥離部７２２ｅ，７２２ｆの跡には、金属膜７２２Ａを貫通して基材７２１を露出させる第１及び第２貫通部７２３ｅ，７２３ｆが形成される。第１及び第２貫通部７２３ｅ，７２３ｆは、第１及び第２剥離部７２２ｅ，７２２ｆにそれぞれ対応する形状である。第１及び第２貫通部７２３ｅ，７２３ｆは、枠部７２３ｂにつながる。これにより、第１及び第２貫通部７２３ｅ，７２３ｆと溝部７２３ａと枠部７２３ｂとがスリット７２３Ａを構成する。スリット７２３Ａにより、金属膜７２２Ａのループアンテナパターン７２２ｂが破損して、ＲＦＩＤモジュール７３０に対して、ループアンテナとして機能しなくなる。これによって、ＲＦＩＤモジュール７３０は、金属膜７２２Ａを利用した通信を行うことができなくなる。そのため、ＲＦＩＤ機能が無効化される。 43 is a bottom view of the lid 720A separated from the main body 710. FIG. By peeling the lid 720A from the main body 710, the first and second peeling portions 722e and 722f are removed from the metal film 722A. Therefore, first and second penetrating portions 723e and 723f that penetrate the metal film 722A and expose the substrate 721 are formed at the traces of the first and second peeling portions 722e and 722f. The first and second penetrating portions 723e and 723f have shapes corresponding to the first and second peeling portions 722e and 722f, respectively. The first and second through portions 723e and 723f are connected to the frame portion 723b. Thereby, the first and second through portions 723e and 723f, the groove portion 723a, and the frame portion 723b constitute the slit 723A. Due to the slit 723A, the loop antenna pattern 722b of the metal film 722A is damaged and does not function as a loop antenna for the RFID module 730. FIG. As a result, the RFID module 730 cannot perform communication using the metal film 722A. Therefore, the RFID function is disabled.
　別の変形例では、金属膜は、ループアンテナパターンではなくダイポールアンテナパターンを構成してよい。この場合、金属膜は、金属膜の剥離部が蓋から剥離されることで、ダイポールアンテナパターンが破損するように構成されてよい。つまり、金属膜に形成されるアンテナパターンとしては、実施の形態１及び実施の形態２で述べたような種々のアンテナパターンを適用できる。 In another variation, the metal film may form a dipole antenna pattern rather than a loop antenna pattern. In this case, the metal film may be configured such that the dipole antenna pattern is damaged when the peeled portion of the metal film is peeled off from the lid. That is, various antenna patterns as described in the first and second embodiments can be applied as the antenna pattern formed on the metal film.
　［２．変形例］
　本開示の実施の形態は、上記実施の形態に限定されない。上記実施の形態は、本開示の課題を達成できれば、設計等に応じて種々の変更が可能である。以下に、上記実施の形態の変形例を列挙する。以下に説明する変形例は、適宜組み合わせて適用可能である。 [2. Modification]
Embodiments of the present disclosure are not limited to the above embodiments. The above-described embodiment can be modified in various ways according to the design, etc., as long as the subject of the present disclosure can be achieved. Modifications of the above embodiment are listed below. Modifications described below can be applied in combination as appropriate.
　実施の形態１に関して、ＲＦＩＤ機能付き容器１００の材料及び寸法、例えば、本体１１０及び蓋１２０の材料及び形状は、適宜変更されてよい。本体１１０及び蓋１２０の材料及び形状は、例えば、内容物Ｎ１００の性質等に応じて適宜決定されてよい。この点は、実施の形態２～実施の形態７においても同様である。 Regarding Embodiment 1, the material and dimensions of the container 100 with RFID function, for example, the material and shape of the main body 110 and lid 120 may be changed as appropriate. The materials and shapes of the main body 110 and the lid 120 may be appropriately determined according to, for example, the properties of the contents N100. This point also applies to the second to seventh embodiments.
　実施の形態１に関して、蓋１２０は、剥離可能に本体１１０に取り付けられているが、必ずしも剥離可能に本体１１０に取り付けられていなくてもよい。例えば、蓋１２０は、機械的な構造により、取り外し可能に本体１１０に取り付けられてもよい。機械的な構造の例としては、例えば、雄ネジと雌ネジを用いた構造が挙げられる。例えば、蓋１２０は、必ずしも本体１１０から取り外し可能である必要はなく、本体１１０から内容物Ｎ１００を取り出すために蓋１２０に孔が開けられるように蓋１２０自体が破損されてもよい。蓋１２０を本体１１０に取り付けることができれば、その取り付け方法は特に制限されない。この点は、実施の形態２～実施の形態７においても同様である。 Regarding Embodiment 1, the lid 120 is releasably attached to the main body 110, but it does not necessarily have to be releasably attached to the main body 110. For example, lid 120 may be removably attached to body 110 by a mechanical structure. Examples of mechanical structures include structures using male and female threads. For example, the lid 120 need not necessarily be removable from the main body 110, and the lid 120 itself may be broken such that the lid 120 is punctured to remove the contents N100 from the main body 110. As long as the lid 120 can be attached to the main body 110, the attachment method is not particularly limited. This point also applies to the second to seventh embodiments.
　実施の形態１に関して、ＲＦＩＤモジュール１３０の構成は、適宜変更されてよい。例えば、ＲＦＩＤモジュール１３０は、ＲＦＩＣ素子１３４を有するが、並列共振回路（フィルタ回路）ＲＣ１を有しないように構成されてよい。この点は、実施の形態２～実施の形態７においても同様である。 With respect to Embodiment 1, the configuration of the RFID module 130 may be changed as appropriate. For example, RFID module 130 may be configured to have RFIC element 134 but not parallel resonant circuit (filter circuit) RC1. This point also applies to the second to seventh embodiments.
　実施の形態１において、通信用周波数帯はＵＨＦ帯であったがこれに限られない。ＲＦＩＤモジュール１３０は、ＨＦ帯の通信用の周波数（キャリア周波数）を有する高周波信号で無線通信するよう構成されていてもよい。ＨＦ帯は、１３ＭＨｚ以上１５ＭＨｚ以下の周波数帯域である。この点は、実施の形態２～実施の形態７においても同様である。 Although the communication frequency band is the UHF band in Embodiment 1, it is not limited to this.
