第４の態様は、第１〜第３のいずれか一つの態様に係る抽出器であって、前記抽出網の他方側開口部に、外側又は内側に張出すつば部が形成されている。 A 4th aspect is an extractor which concerns on any one 1st- 3rd aspect, Comprising: The collar part protruding outside or inside is formed in the other side opening part of the said extraction net | network.

第５の態様は、第１〜第４のいずれか一つの態様に係る抽出器であって、前記蓋部が前記抽出容器部の開口部に装着された状態で、前記抽出網の一方側開口部縁部が前記凹部に嵌め込まれる関係を維持するように、前記蓋部が前記抽出網の他方側開口部に当接する。 A fifth aspect is the extractor according to any one of the first to fourth aspects, wherein one side opening of the extraction net is provided in a state where the lid part is attached to the opening part of the extraction container part. The lid portion abuts against the other opening of the extraction net so as to maintain the relationship that the edge portion is fitted into the recess.

第１の態様によると、前記抽出網の一方側の開口部は、前記凹部の上方開口部と最底部との間に位置した状態で前記凹部に嵌め込まれるため、非抽出容器部から抽出網を容易に取外すことができる。また、抽出網内に投入された被抽出物の少なくとも一部は、抽出網の一方側開口部よりも底側で凹部内に貯まるため、抽出網内から漏出し難くなる。また、前記抽出網の一方側の開口部を、凹部の同径部分の任意の位置に嵌め込むことができるため、抽出網の装着を容易に行える。また、前記抽出網の一方側開口部に装着された弾性環状部材を、凹部の内周面に密着させることができる。これにより、抽出網の一方側開口部と凹部との隙間をより確実に小さくして、抽出網内からの被抽出物の漏出をより確実に抑制できる。 According to the first aspect, the opening on one side of the extraction mesh is fitted into the recess in a state located between the upper opening and the bottom of the recess, so that the extraction mesh is removed from the non-extraction container portion. Can be easily removed. In addition, at least a part of the extraction material put into the extraction net is stored in the recess at the bottom side of the opening on one side of the extraction net, so that it is difficult to leak from the extraction net. Moreover, since the opening part of the one side of the said extraction net | network can be engage | inserted in the arbitrary positions of the same diameter part of a recessed part, mounting | wearing of an extraction net | network can be performed easily. Further, the elastic annular member attached to the one side opening of the extraction net can be brought into close contact with the inner peripheral surface of the recess. Thereby, the clearance gap between the one side opening part and recessed part of an extraction net | network can be made small more reliably, and the leakage of the to-be-extracted substance from the inside of an extraction net | network can be suppressed more reliably.

第２の態様によると、前記抽出網の一方側の開口部は、前記凹部の上方開口部と最底部との間に位置した状態で前記凹部に嵌め込まれるため、非抽出容器部から抽出網を容易に取外すことができる。また、抽出網内に投入された被抽出物の少なくとも一部は、抽出網の一方側開口部よりも底側で凹部内に貯まるため、抽出網内から漏出し難くなる。また、前記抽出網の一方側の開口部を、凹部の同径部分の任意の位置に嵌め込むことができるため、抽出網の装着を容易に行える。また、前記抽出網の一方側開口部に形成されたつば部によって、抽出網の一方側開口部の変形を抑制できる。これにより、前記抽出網の一方側の開口部と凹部の内周面との間での隙間の発生を抑制することができる。 According to the second aspect, since the opening on one side of the extraction mesh is fitted into the recess in a state located between the upper opening and the bottom of the recess, the extraction mesh is removed from the non-extraction container portion. Can be easily removed. In addition, at least a part of the extraction material put into the extraction net is stored in the recess at the bottom side of the opening on one side of the extraction net, so that it is difficult to leak from the extraction net. Moreover, since the opening part of the one side of the said extraction net | network can be engage | inserted in the arbitrary positions of the same diameter part of a recessed part, mounting | wearing of an extraction net | network can be performed easily. Moreover, the deformation | transformation of the one side opening part of an extraction net | network can be suppressed by the collar part formed in the one side opening part of the said extraction net | network. Thereby, generation | occurrence | production of the clearance gap between the opening part of the one side of the said extraction net | network and the internal peripheral surface of a recessed part can be suppressed.

第３の態様によると、抽出網の一方側開口部を凹部の細径変化部分に嵌め込んでいくと、抽出網の一方側開口部と凹部との隙間が徐々に小さくなるため、抽出網内からの被抽出物の漏出をより確実に抑制できる。 According to the third aspect, when the one side opening of the extraction net is fitted into the small diameter change portion of the concave portion, the gap between the one side opening of the extraction net and the concave portion is gradually reduced. Leakage of the extractable substance from can be more reliably suppressed.

第４の態様によると、前記抽出網の他方側開口部に形成されたつば部によって、抽出網の他方側開口部の変形を抑制できる。 According to the 4th aspect, the deformation | transformation of the other side opening part of an extraction net | network can be suppressed by the collar part formed in the other side opening part of the said extraction net | network.

第５の態様によると、蓋部が抽出網を押え込んでいるため、前記抽出網の一方側開口部と前記周壁部とが嵌まり合う関係がより確実に維持される。これにより、被抽出物の通過をより確実に抑制することができる。 According to the 5th aspect, since the cover part has pressed down the extraction net | network, the relationship where the one side opening part of the said extraction net | network and the said surrounding wall part fit is maintained more reliably.

以下、実施形態に係る抽出器について説明する。ここでは、抽出器として、ポットを想定した例で説明する。図１は実施形態に係るポット１０を示す分解斜視図であり、図２はポット１０の断面図であり、図３は図２の部分拡大図である。 Hereinafter, the extractor according to the embodiment will be described. Here, an example in which a pot is assumed as the extractor will be described. 1 is an exploded perspective view showing a pot 10 according to the embodiment, FIG. 2 is a cross-sectional view of the pot 10, and FIG. 3 is a partially enlarged view of FIG.

このポット１０は、被抽出物（例えば、日本茶或は紅茶等の茶葉、コーヒー等）から、茶成分、コーヒー成分等の飲料成分を抽出するための装置、即ち、飲料を生成するための装置である。 The pot 10 is a device for extracting beverage components such as tea components and coffee components from an extract (for example, tea leaves such as Japanese tea or black tea, coffee, etc.), that is, a device for producing a beverage. It is.

ポット１０は、抽出容器部としての容器部２０と、蓋部１２と、抽出網３０とを有している。 The pot 10 has a container part 20 as an extraction container part, a lid part 12, and an extraction net 30.

容器部２０は、容器本体部２２と、注ぎ口部２８と、取っ手部２９とを有している。 The container part 20 has a container main body part 22, a spout part 28, and a handle part 29.

容器本体部２２は、上方に開口部２７を有する器状に形成されている。より具体的には、容器本体部２２は、高さ方向中間部が太く、かつ、上部及び下部が前記中間部よりも細い器状に形成されており、内部に液体を貯留できるようになっている。 The container body 22 is formed in a container shape having an opening 27 on the upper side. More specifically, the container body portion 22 has a thick middle in the height direction and is formed in a container shape whose upper and lower portions are thinner than the intermediate portion, and can store liquid therein. Yes.

容器本体部２２の底部２３の外面は平らに形成されており、また、底部２３の内面には、円状に凹む凹部２４が形成されている（図２参照）。凹部２４は、円状の最底部２５と、最底部２５の周りを囲む内向きの周壁部２６とを有している。凹部２４は、抽出網３０の一方側（下方側）開口部を、凹部２４の上方開口部と最底部との間に位置させた状態で、嵌め込み可能な形状及び大きさに形成されている。 The outer surface of the bottom part 23 of the container main body part 22 is formed flat, and the recessed part 24 dented circularly is formed in the inner surface of the bottom part 23 (refer FIG. 2). The concave portion 24 includes a circular bottom portion 25 and an inward peripheral wall portion 26 surrounding the bottom portion 25. The recessed part 24 is formed in a shape and size that can be fitted in a state where the opening part on one side (lower side) of the extraction net 30 is located between the upper opening part and the bottom part of the recessed part 24.

より具体的には、周壁部２６は、上方開口部側に同径部分２６ａを有すると共に、最底部２５側に細径変化部分２６ｂを有している。 More specifically, the peripheral wall portion 26 has the same-diameter portion 26a on the upper opening side, and has the small-diameter changing portion 26b on the bottom portion 25 side.

同径部分２６ａは、上下方向において内径が同じに形成された部分である。同径部分２６ａの内径は、抽出網の一方側（下側）の開口部の外周部の外径と同じに形成されており、抽出網３０の一方側（下側）の開口部の外周縁部全体を、当該同径部分２６ａの内周面の全体に接触させた状態で、抽出網３０の一方側（下側）の開口部を同径部分２６ａに嵌め込めるようになっている。また、この際、抽出網３０の一方側の開口部を、同径部分２６ａが形成された範囲内で上下方向に移動させても、抽出網３０の一方側の開口部の外周縁部全体を、同径部分２６ａの内周部の全体に接触させた状態を維持できるようになっている。 The same-diameter portion 26a is a portion formed with the same inner diameter in the vertical direction. The inner diameter of the same-diameter portion 26a is formed to be the same as the outer diameter of the outer peripheral portion of the opening on one side (lower side) of the extraction net, and the outer peripheral edge of the opening on one side (lower side) of the extraction net 30 The opening on one side (lower side) of the extraction mesh 30 can be fitted into the same-diameter portion 26a in a state where the entire portion is in contact with the entire inner peripheral surface of the same-diameter portion 26a. At this time, even if the opening on one side of the extraction mesh 30 is moved in the vertical direction within the range where the same-diameter portion 26a is formed, the entire outer peripheral edge of the opening on the one side of the extraction mesh 30 is removed. The state in which the entire inner peripheral portion of the same diameter portion 26a is brought into contact with each other can be maintained.

細径変化部分２６ｂは、同径部分２６ａの下端部から最底部２５に向けて、内径が順次小さくなるように形成された部分である。つまり、最底部２５の外周縁の径は、同径部分２６ａの内径よりも小さくなっており、細径変化部分２６ｂの内周面は、外向きに凸となる湾曲曲面を描きつつ、同径部分２６ａの下端部内周面から徐々に狭まりつつ最底部２５の外周縁部に至るようになっている。 The small diameter changing portion 26b is a portion formed so that the inner diameter gradually decreases from the lower end of the same diameter portion 26a toward the bottom 25. That is, the diameter of the outer peripheral edge of the bottom 25 is smaller than the inner diameter of the same-diameter portion 26a, and the inner peripheral surface of the small-diameter changing portion 26b has the same diameter while drawing a curved curved surface that protrudes outward. The outer peripheral edge of the bottom 25 is gradually narrowed from the inner peripheral surface of the lower end of the portion 26a.

そして、抽出網３０の一方側（下側）の開口部を、同径部分２６ａを越えて細径変化部分２６ｂ内に押込むように嵌め込むと、抽出網の一方側開口部が細径変化部分２６ｂの内周面に強く押し当てられ、抽出網３０の一方側の開口部と凹部２４の内周面の隙間とがより小さくなる。 Then, when the opening on one side (lower side) of the extraction mesh 30 is fitted so as to be pushed into the small diameter changing portion 26b beyond the same diameter portion 26a, the one side opening on the extraction net 30 becomes the small diameter changing portion 26b. Is strongly pressed against the inner peripheral surface of the squeezing plate, and the opening on one side of the extraction mesh 30 and the clearance between the inner peripheral surface of the recess 24 become smaller.

なお、凹部２４が円状の凹部であることは必須ではなく、楕円状、多角形状等であってもよい。つまり、抽出網３０の一方側の開口部と凹部２４とが、相互に対応する略相似形状に形成され、相互に嵌まり合う形状であればよい。また、上記同径部分２６ａ及び細径変化部分２６ｂの一方が省略されていてもよい。 In addition, it is not essential that the recessed part 24 is a circular recessed part, and elliptical shape, polygonal shape, etc. may be sufficient. That is, it is sufficient that the opening on one side of the extraction net 30 and the concave portion 24 are formed in substantially similar shapes corresponding to each other and fit into each other. One of the same diameter portion 26a and the small diameter changing portion 26b may be omitted.

開口部２７は、容器本体部２２の上方で、上向きに開口している。ここでは、容器本体部２２の上方端縁部よりも（ここでは若干）下側部分が絞り込まれるように細径に形成されることで、細径開口部分２７ａと、当該細径開口部分２７ａより上方に向けて順次拡開する拡開縁部分２７ｂとを有する開口部２７が形成されている。なお、開口部２７の細径開口部分２７ａの内径は、周壁部２６よりも大きい（ここでは僅かに大きい）。そして、液体を、開口部２７を通じて容器本体部２２内に注ぎ、また、その液体を容器本体部２２内に貯留できるようになっている。また、拡開縁部分２７ｂの内面部分上に上記蓋部１２の周縁部を載置することで、蓋部１２が開口部２７を閉塞するように、容器本体部２２に装着されるようになっている。 The opening 27 opens upward above the container body 22. Here, by forming a small diameter so that the lower portion is narrowed down (slightly here) from the upper edge of the container body 22, the narrow opening portion 27 a and the narrow opening portion 27 a An opening 27 having an expanded edge portion 27b that expands sequentially upward is formed. In addition, the internal diameter of the small diameter opening part 27a of the opening part 27 is larger than the surrounding wall part 26 (here it is slightly large). Then, the liquid is poured into the container main body 22 through the opening 27, and the liquid can be stored in the container main body 22. Further, by placing the peripheral edge portion of the lid portion 12 on the inner surface portion of the expanded edge portion 27b, the lid portion 12 is attached to the container main body portion 22 so as to close the opening portion 27. ing.

注ぎ口部２８は、開口部２７の周縁部の一部を外下方に向けて引出したような、半筒状形状に形成されている。蓋部１２を容器本体部２２に装着した状態で、注ぎ口部２８の内周面と蓋部１２の外周縁部との間に、液体が通過可能な隙間が形成される。また、注ぎ口部２８の先端部は、外下方に向けて開口している。そして、注ぎ口部２８の先端部を下方に向けるように、容器部２０を傾けると、容器本体部２２内の液体が注ぎ口部２８を通って外部に流れ出るようになっている。 The spout portion 28 is formed in a semi-cylindrical shape such that a part of the peripheral edge portion of the opening portion 27 is drawn outward and downward. With the lid 12 attached to the container body 22, a gap through which liquid can pass is formed between the inner peripheral surface of the spout portion 28 and the outer peripheral edge of the lid 12. Moreover, the front-end | tip part of the spout part 28 is opened toward the outer downward direction. And if the container part 20 is inclined so that the front-end | tip part of the spout part 28 may face downward, the liquid in the container main-body part 22 will flow out through the spout part 28 outside.

取っ手部２９は、容器本体部２２の他の一側部の高さ方向上部から外方を迂回して高さ方向中間部に至るＣ字状形状に形成されている。容器本体部２２の平面視において、注ぎ口部２８と取っ手部２９とは反対側の位置に設けられている。そして、本ポット１０の利用者が、手で取っ手部２９を掴むことによって、ポット１０を持上げて当該ポット１０を傾けることにより、上記注ぎ口部２８から湯飲み等に飲料（お茶）を注ぐことができるようになっている。このように容器本体部２２の一側部に固定される取っ手部２９の他、容器本体部をぶら下げるようにして支持する取っ手等であってもよく、また、取っ手は省略されてもよい。 The handle portion 29 is formed in a C-shape that bypasses the outside from the upper portion in the height direction of the other side portion of the container main body portion 22 and reaches the intermediate portion in the height direction. In the plan view of the container main body portion 22, the spout portion 28 and the handle portion 29 are provided at positions opposite to each other. Then, the user of the pot 10 can pour a drink (tea) from the spout portion 28 into a cup of hot water by grabbing the handle portion 29 with his hand and tilting the pot 10. It can be done. In addition to the handle portion 29 fixed to one side portion of the container body portion 22 as described above, a handle or the like that supports the container body portion so as to be suspended may be used, and the handle may be omitted.

蓋部１２は、上記開口部２７に着脱可能に装着されるように構成されている。より具体的には、蓋部１２は、浅い皿状形状に形成され、その外径は、上記開口部２７の細径開口部分２７ａの内径よりも大きく、かつ、拡開縁部分２７ｂの上側開口縁部の外径よりも小さく設定されている。そして、蓋部１２の外周縁部を、拡開縁部分２７ｂの内面部分上に載置することで、蓋部１２で開口部２７を閉塞できるようになっている。この状態では、拡開縁部分２７ｂが蓋部１２を取り囲むことによって、当該蓋部１２が位置決めされた状態となっている。もっとも、蓋部の内面側に形成された環状突部を、開口部の内周縁部に当接させて、蓋部の位置決めを図るようにしてもよい。 The lid portion 12 is configured to be detachably attached to the opening portion 27. More specifically, the lid portion 12 is formed in a shallow dish shape, the outer diameter thereof is larger than the inner diameter of the narrow opening portion 27a of the opening portion 27, and the upper opening of the widened edge portion 27b. It is set smaller than the outer diameter of the edge. And the opening part 27 can be obstruct | occluded by the cover part 12 by mounting the outer peripheral part of the cover part 12 on the inner surface part of the expansion edge part 27b. In this state, the expanded edge portion 27b surrounds the lid portion 12, and thus the lid portion 12 is positioned. However, the annular protrusion formed on the inner surface side of the lid may be brought into contact with the inner peripheral edge of the opening to position the lid.

また、上記状態から、蓋部１２を上方に持上げることによって、蓋部１２を開口部２７から取外せるようになっている。なお、蓋部１２の外面（上面）の略中央部には、つまみ部１３が突設されており、利用者が手でつまみ部１３をつまむことによって、当該蓋部１２を開口部２７に対して容易に着脱できるようになっている。 Also, from the above state, the lid 12 can be removed from the opening 27 by lifting the lid 12 upward. In addition, a knob portion 13 is projected at a substantially central portion of the outer surface (upper surface) of the lid portion 12, and when the user pinches the knob portion 13 by hand, the lid portion 12 is moved with respect to the opening portion 27. Can be easily attached and detached.

抽出網３０は、網目を有する筒状に形成され、開口部２７を通って容器部２０内に配設可能に構成されている。 The extraction net 30 is formed in a cylindrical shape having a mesh, and is configured to be disposed in the container part 20 through the opening 27.

より具体的には、抽出網３０は、網部３２と、上枠部３４と、下枠部３６と、弾性環状部材３８とを有している。 More specifically, the extraction net 30 includes a net part 32, an upper frame part 34, a lower frame part 36, and an elastic annular member 38.

網部３２は、網材を筒状に形成した構成とされている。ここでは、網部３２は、軸方向に沿って径が同じである筒状に形成されている。網部３２が軸方向に沿って径が同じである筒状であることは必須ではないが、そのような形状であれば、面状に広がる網材から網部３２を容易に製造できるという利点がある。網材としては、ステンレス細線で形成されたステンレス製の網材、その他の金属製の網、樹脂製の網、植物性の網等を用いることができる。また、網材を筒状に加工する際に接続箇所が発生する際には、溶接等で接合してもよいし、当該網材の端部を重ねて配設するだけであってもよい。 The net part 32 has a configuration in which a net material is formed in a cylindrical shape. Here, the net part 32 is formed in a cylindrical shape having the same diameter along the axial direction. Although it is not essential that the net part 32 has a cylindrical shape having the same diameter along the axial direction, the net part 32 can be easily manufactured from a net material spreading in a plane if such a shape is used. There is. As the mesh material, a stainless steel mesh material formed of stainless fine wires, other metal meshes, resin meshes, vegetable meshes, and the like can be used. In addition, when a connection portion is generated when the mesh material is processed into a cylindrical shape, the mesh material may be joined by welding or the like, or only the end portions of the mesh material may be disposed so as to overlap each other.

上枠部３４は、ステンレス製の帯板材等を円状に曲げると共に、網部３２の他方側（上側）の端縁部開口を挟込むように二つ折り状に折曲げることにより形成されている。 The upper frame portion 34 is formed by bending a stainless steel strip or the like into a circular shape and bending it in a double fold shape so as to sandwich the opening on the other side (upper side) of the net portion 32. .

また、ここでは、上枠部３４の上端部を外側に向けて折曲げることで、抽出網３０の外側に張出すつば部３４ａが形成されている。つば部３４ａの外径は、開口部２７の内径と同じ値か又は小さい値に設定されている。このつば部３４ａは、抽出網３０の軸方向に対して直交する方向に延在する板部材として存在することで、抽出網３０の他方側（下側）の開口部の変形を抑制する役割を有している。なお、つば部３４ａは、抽出網３０の内側に張出す形状であってもよい。もっとも、つば部３４ａが抽出網３０の内側に張出すことで、抽出網３０を容器部２０内に配設した状態で、網部３２と開口部２７との隙間を可及的に塞ぐことができる。これにより、抽出網３０内に被抽出物を投入する際に、被抽出物が容器部２０内であって抽出網３０外にこぼれ落ちることを抑制できる。 In addition, here, a flange portion 34 a that protrudes outside the extraction mesh 30 is formed by bending the upper end portion of the upper frame portion 34 outward. The outer diameter of the collar portion 34 a is set to the same value as or smaller than the inner diameter of the opening portion 27. The collar portion 34 a exists as a plate member extending in a direction orthogonal to the axial direction of the extraction mesh 30, thereby suppressing the deformation of the opening on the other side (lower side) of the extraction mesh 30. Have. The collar portion 34 a may have a shape that protrudes inside the extraction net 30. However, since the collar portion 34a projects to the inside of the extraction mesh 30, the gap between the mesh portion 32 and the opening 27 can be closed as much as possible in a state where the extraction mesh 30 is disposed in the container portion 20. it can. Thereby, when the extract is put into the extraction net 30, it can be suppressed that the extract is spilled out of the extraction net 30 in the container portion 20.

もっとも、上枠部３４は必須ではないし、また、つば部３４ａも必須ではない。 But the upper frame part 34 is not essential, and the collar part 34a is not essential.

下枠部３６は、ステンレス製の帯板材等を円状に曲げると共に、網部３２の一方側（下側）の端縁部開口を挟込むように二つ折り状に折曲げることにより形成されている。また、ここでは、下枠部３６の下端部を外側に向けて折曲げることで、抽出網３０の外側に張出すつば部３６ａが形成されている。つば部３６ａの外径は、凹部２４の同径部分２６ａの内径と同じ値か又は小さい値に設定されていることが好ましい。ここでは、弾性環状部材３８の装着を考慮した分、つば部３６ａの外径は、凹部２４の同径部分２６ａの内径よりも小さい値に設定されている。このつば部３６ａは、抽出網３０の軸方向に対して直交する方向に延在する板部材として存在することで、抽出網３０の一方側（上側）の開口部の変形を抑制する役割を有している。なお、つば部３６ａは、抽出網３０の内側に張出す形状であってもよい。 The lower frame portion 36 is formed by bending a stainless steel strip material or the like into a circular shape and bending it in a double fold shape so as to sandwich an end edge opening on one side (lower side) of the mesh portion 32. Yes. In addition, here, a flange portion 36 a that protrudes outside the extraction net 30 is formed by bending the lower end portion of the lower frame portion 36 outward. The outer diameter of the collar portion 36a is preferably set to a value that is the same as or smaller than the inner diameter of the same-diameter portion 26a of the recess 24. Here, the outer diameter of the collar portion 36a is set to a value smaller than the inner diameter of the same-diameter portion 26a of the recess 24 by considering the mounting of the elastic annular member 38. The flange portion 36 a exists as a plate member extending in a direction orthogonal to the axial direction of the extraction mesh 30, thereby suppressing the deformation of the opening on one side (upper side) of the extraction mesh 30. is doing. Note that the collar portion 36 a may have a shape that protrudes to the inside of the extraction net 30.

もっとも、下枠部３６は必須ではないし、また、つば部３６ａも必須ではない。 However, the lower frame portion 36 is not essential, and the collar portion 36a is not essential.

弾性環状部材３８は、抽出網３０の一方側（下側）の開口部に装着された部材である。より具体的には、弾性環状部材３８は、シリコーンゴム、合成ゴム等のエラストマーによって形成されている。ここでは、弾性環状部材３８は、つば部３６ａの外径よりも小さい内径で、かつ、凹部２４の同径部分２６ａの内径と略同じ外径を有する環状部材に形成されている。また、弾性環状部材３８の内周部に、つば部３６ａを嵌め込み可能な環状溝３８ｂが形成されている（図３参照）。弾性環状部材３８をつば部３６ａの外側に被せるようにして、つば部３６ａの外周縁部を環状溝３８ｂに嵌め込むことで、弾性環状部材３８が抽出網３０の一方側の開口部に装着される。 The elastic annular member 38 is a member attached to the opening on one side (lower side) of the extraction net 30. More specifically, the elastic annular member 38 is formed of an elastomer such as silicone rubber or synthetic rubber. Here, the elastic annular member 38 is formed as an annular member having an inner diameter smaller than the outer diameter of the flange portion 36a and substantially the same outer diameter as the inner diameter of the same-diameter portion 26a of the recess 24. Further, an annular groove 38b into which the flange portion 36a can be fitted is formed on the inner peripheral portion of the elastic annular member 38 (see FIG. 3). The elastic annular member 38 is attached to the opening on one side of the extraction net 30 by fitting the outer peripheral edge of the collar portion 36a into the annular groove 38b so that the elastic annular member 38 is placed on the outer side of the collar portion 36a. The

この抽出網３０を容器部２０内に装着する際には、弾性環状部材３８が凹部２４内に嵌め込まれる。この際、弾性環状部材３８が、凹部２４の同径部分２６ａ内においてその上下方向任意の位置に嵌め込まれることで、当該弾性環状部材３８の外周部が同径部分２６ａの内周面に接する。これにより、容器部２０内において抽出網３０の内外空間がより確実に仕切られる。また、弾性環状部材３８が、凹部２４の同径部分２６ａを越えて細径変化部分２６ｂに押込まれると、弾性環状部材３８の外周部が細径変化部分２６ｂの内周面に強く押し当てられる。これにより、容器部２０内において抽出網３０の内外空間がより確実に仕切られるようになる。 When the extraction net 30 is mounted in the container part 20, the elastic annular member 38 is fitted in the recess 24. At this time, the elastic annular member 38 is fitted in an arbitrary position in the vertical direction within the same-diameter portion 26a of the recess 24, so that the outer peripheral portion of the elastic annular member 38 contacts the inner peripheral surface of the same-diameter portion 26a. Thereby, the inner and outer spaces of the extraction net 30 are more reliably partitioned in the container part 20. Further, when the elastic annular member 38 is pushed into the small diameter changing portion 26b beyond the same diameter portion 26a of the recess 24, the outer peripheral portion of the elastic annular member 38 is strongly pressed against the inner peripheral surface of the small diameter changing portion 26b. It is done. Thereby, the inner and outer spaces of the extraction net 30 are more reliably partitioned in the container part 20.

なお、下枠部３６のつば部３６ａを省略した場合、弾性環状部材は枠部の下側より嵌め込まれてもよい。また、下枠部３６を省略した場合、弾性環状部材は網部の一方側（下側）の開口部に直接装着されてもよい。また、弾性環状部材３８は省略されてもよい。 When the collar portion 36a of the lower frame portion 36 is omitted, the elastic annular member may be fitted from the lower side of the frame portion. When the lower frame portion 36 is omitted, the elastic annular member may be directly attached to the opening on one side (lower side) of the net portion. Further, the elastic annular member 38 may be omitted.

なお、抽出網３０は、全体として容器部２０の開口部２７よりも小さな径の筒状に形成されており、当該開口部２７を通って容器部２０内に配設できるようになっている。 The extraction net 30 is formed in a cylindrical shape having a smaller diameter than the opening 27 of the container part 20 as a whole, and can be disposed in the container part 20 through the opening 27.

また、抽出網３０の軸方向における高さ寸法は、蓋部１２が開口部２７に装着された状態で、抽出網３０の一方側（下側）開口部が凹部２４に嵌め込まれる関係を維持するように、蓋部１２が抽出網３０の他方側（上側）開口部に当接するように設定されている。ここでは、抽出網３０の高さ寸法は、凹部２４の周壁部２６における同径部分２６ａと細径変化部分２６ｂとの境界と、蓋部１２の内面のうち周壁部２６の上方部分までの距離Ｈと略同じになるように設定されている。 Further, the height dimension in the axial direction of the extraction net 30 maintains the relationship in which the one side (lower side) opening of the extraction net 30 is fitted in the recess 24 in a state where the lid 12 is attached to the opening 27. As described above, the lid 12 is set so as to contact the other side (upper side) opening of the extraction net 30. Here, the height dimension of the extraction mesh 30 is the distance from the boundary between the same-diameter portion 26a and the small-diameter changing portion 26b in the peripheral wall portion 26 of the recess 24 to the upper portion of the peripheral wall portion 26 on the inner surface of the lid portion 12. It is set to be substantially the same as H.

これにより、抽出網３０を容器部２０内に配設した状態で、抽出網３０の一方側（下側）の開口部が凹部２４内に十分に嵌め込まれていない状態であっても、蓋部１２を開口部２７に装着すると、抽出網３０が押込まれ、その一方側開口部が凹部２４内に十分に押込まれる。また、抽出網３０を容器部２０内に配設した状態で、蓋部１２が自重によって抽出網３０を容器部２０内に押込む。また、ポット１０からカップ等に飲料を注ぐ場合に、利用者が手で蓋部１２を押えると、その押え込みの力によっても、抽出網３０の一方側開口部が凹部２４に押込まれる。このため、抽出網３０の一方側開口部とポット１０の内面である凹部２４との間の隙間がより確実に閉ざされることとなる。 As a result, even if the opening on one side (lower side) of the extraction mesh 30 is not sufficiently fitted in the recess 24 in a state where the extraction mesh 30 is disposed in the container portion 20, the lid portion When 12 is attached to the opening 27, the extraction net 30 is pushed in, and the opening on one side is sufficiently pushed into the recess 24. In addition, the lid 12 pushes the extraction net 30 into the container part 20 by its own weight while the extraction net 30 is disposed in the container part 20. When a user pours a beverage from the pot 10 into a cup or the like, when the user presses the lid 12 by hand, the opening on one side of the extraction net 30 is pushed into the recess 24 by the pressing force. For this reason, the clearance gap between the one side opening part of the extraction net | network 30 and the recessed part 24 which is the inner surface of the pot 10 will be closed more reliably.

もっとも、抽出網３０の高さ寸法を上記のように設定することは必須でなく、抽出網３０を容器部２０内に装着した状態で、蓋部１２を装着しても、抽出網３０の他方側（上側）の開口部が蓋部１２に接しない構成であってもよい。 However, it is not essential to set the height dimension of the extraction mesh 30 as described above. Even if the lid 12 is attached in a state where the extraction mesh 30 is attached in the container portion 20, the other of the extraction mesh 30 can be set. The side (upper side) opening may not be in contact with the lid 12.

このように構成されたポット１０の使用方法について説明する。 The usage method of the pot 10 comprised in this way is demonstrated.

まず、空の容器部２０内に、開口部２７を通って抽出網３０を配設し、抽出網３０の一方側（下側）の開口部を凹部２４内に嵌め込む。この際、抽出網３０の一方側（下側）の開口部を凹部２４の細径変化部分２６ｂに嵌め込むことが好ましい。もっとも、これは必須ではなく、抽出網３０の一方側（下側）の開口部が凹部２４の同径部分２６ａに嵌め込まれていてもよい。 First, the extraction net 30 is disposed in the empty container portion 20 through the opening 27, and the opening on one side (lower side) of the extraction net 30 is fitted into the recess 24. At this time, it is preferable to fit the opening on one side (lower side) of the extraction net 30 into the small diameter changing portion 26 b of the recess 24. However, this is not essential, and the opening on one side (lower side) of the extraction net 30 may be fitted into the same-diameter portion 26 a of the recess 24.

この状態で、容器部２０の上方の開口部２７内に配設された、抽出網３０の他方側（上側）開口を通って、抽出網３０内に被抽出物を投入する。この際、上枠部３４のつば部３６ａによって、抽出網３０の他方側（上側）の開口部と容器部２０の開口部２７の縁部との間の隙間がなるべく小さくなるように塞がれているため、被抽出物が抽出網３０からこぼれ難い。 In this state, the substance to be extracted is put into the extraction net 30 through the other side (upper side) opening of the extraction net 30 disposed in the opening 27 above the container part 20. At this time, the flange portion 36a of the upper frame portion 34 closes the gap between the opening portion on the other side (upper side) of the extraction mesh 30 and the edge portion of the opening portion 27 of the container portion 20 as much as possible. Therefore, the extractables are not easily spilled from the extraction network 30.

この後、お湯を、容器部２０の上方の開口部２７を通って容器部２０内に注ぐ。この際、抽出網３０内空間の底は、容器部２０の底と一致している。このため、容器部２０に注がれたお湯が少量であっても、被抽出物は当該お湯に浸される。このため、少量のお湯であっても、被抽出物からその飲料成分等を十分に抽出することができる。 Thereafter, hot water is poured into the container part 20 through the opening 27 above the container part 20. At this time, the bottom of the space in the extraction net 30 coincides with the bottom of the container part 20. For this reason, even if the hot water poured into the container part 20 is a small amount, the to-be-extracted object is immersed in the said hot water. For this reason, even if it is a small amount of hot water, the drink component etc. can fully be extracted from a to-be-extracted thing.

容器部２０内にお湯を注いだ後、蓋部１２を装着し、飲料成分を抽出するのに適切な時間が経過すると、利用者が手で取っ手部２９を持って、ポット１０を持上げ、注ぎ口部２８を下方に向けるようにポット１０を傾ける。すると、容器部２０内において抽出成分が溶け込んだお湯、即ち、飲料が、注ぎ口部２８から流れ出て、注ぎ口部２８の下方にある湯飲み等の容器に注がれる。 After pouring hot water into the container part 20, the lid part 12 is attached, and when an appropriate time elapses for extracting the beverage components, the user holds the handle part 29 by hand, lifts the pot 10 and pours it. The pot 10 is tilted so that the mouth portion 28 faces downward. Then, the hot water in which the extracted components are dissolved in the container portion 20, that is, the beverage, flows out from the spout portion 28 and is poured into a container such as a hot drink under the spout portion 28.

この際、抽出成分が溶け込んだお湯（飲料）が抽出網３０を通過し、被抽出物は抽出網３０内に残存する。また、お湯は、筒状の抽出網３０の周り全体を使って濾過されるため、濾過面積を比較的大きくすることができる。これにより、飲料を円滑に注ぎ出すことができる。また、抽出網３０の一方（下方）側の開口部と凹部２４とが嵌まり合った構成であるため、抽出網３０の一方側（下側）の開口部と容器部２０の底内面との間を通った、被抽出物の通過も抑制されている。特に、飲料を注ぐ際に、利用者が蓋部１２を押えることで、抽出網３０の一方側（下側）の開口部と凹部２４とが嵌まり合った構成がより確実に維持されるため、被抽出物の通過がより確実に抑制される。 At this time, hot water (beverage) in which the extracted components are dissolved passes through the extraction net 30, and the extractables remain in the extraction net 30. Moreover, since hot water is filtered using the whole circumference | surroundings of the cylindrical extraction net | network 30, a filtration area can be made comparatively large. Thereby, a drink can be poured out smoothly. Further, since the opening on one side (lower side) of the extraction mesh 30 and the recess 24 are fitted together, the opening on one side (lower side) of the extraction mesh 30 and the bottom inner surface of the container portion 20 The passage of the extract through the space is also suppressed. In particular, when pouring a beverage, the user presses the lid 12, so that the configuration in which the opening on one side (lower side) of the extraction mesh 30 and the recess 24 fit together is more reliably maintained. The passage of the extraction object is more reliably suppressed.

しかも、抽出網３０の一方側（下側）の開口部が、凹部２４の上方開口部と最底部２５との間に位置した状態で凹部２４に嵌め込まれるため、図４に示すように、底に沈んだ被抽出物Ｌ（特に、粉末状の被抽出物Ｌｓ）は、当該凹部２４の底に貯まっている。このため、容器部２０内の底に沈んだ被抽出物Ｌ（特に、粉末状の被抽出物Ｌｓ）が流出し難くなり、注ぎ口部２８から注ぎ出されるお茶に、粉末状の被抽出物Ｌｓ等が混じることが抑制される。 Moreover, since the opening on one side (lower side) of the extraction net 30 is fitted in the recess 24 in a state positioned between the upper opening of the recess 24 and the bottom 25, as shown in FIG. The extractables L (particularly the powdery extractables Ls) that have sunk are stored in the bottom of the recess 24. For this reason, the to-be-extracted substance L (especially powdery to-be-extracted substance Ls) sink | sunk to the bottom in the container part 20 becomes difficult to flow out, and powdery to-be-extracted substance is poured into the tea poured out from the spout part 28. It is suppressed that Ls etc. are mixed.

また、被抽出物Ｌから飲料成分を抽出した後には、本ポット１０を洗浄することになる。この際には、蓋部１２を取外し、抽出網３０を、開口部２７を通って上方に引出す。そして、抽出網３０の全体に勢いよく水を流しかけ、必要に応じブラシ等を使って、抽出網３０に付着していた被抽出物を洗い流す。この際、抽出網３０は、容器部２０から取外されているため、抽出網３０のいずれの位置に対しても、水を流しかけ、また、ブラシ洗浄することができる。また、通常、抽出網３０の内側に被抽出物がこびりつきやすいところ、抽出網３０の外側からも水を流しかけることができるため、付着した被抽出物をより確実に洗い流すことができる。また、容器部２０については、内部に水を流しかけ、あるいは、ブラシで容器部２０の内周面をこする等して、洗浄する。この際、凹部２４は、円状の最底部２５と、最底部２５の周りを囲む内向きの周壁部２６とを有し、細径変化部分２６ｂの内周面は、外向きに凸となる湾曲曲面を描きつつ、同径部分２６ａの下端部内周面から徐々に狭まりつつ最底部２５の外周縁部に至る形状であるため、当該凹部２４をブラシ或は流水等で容易に洗うことができる。その他、容器部２０の外周、蓋部１２等については、一般的なポット１０と同様の方法で洗浄することができる。 Moreover, after extracting a drink component from the to-be-extracted object L, this pot 10 will be wash | cleaned. At this time, the lid 12 is removed, and the extraction net 30 is drawn upward through the opening 27. Then, the entire extraction network 30 is vigorously poured with water, and the extraction object attached to the extraction network 30 is washed away using a brush or the like as necessary. At this time, since the extraction net 30 is removed from the container part 20, water can be poured to any position of the extraction net 30 and brush cleaning can be performed. In addition, usually, the extract is likely to stick to the inside of the extraction net 30, and water can be poured from the outside of the extraction net 30, so that the attached extract can be more reliably washed away. Further, the container part 20 is cleaned by pouring water into the inside or rubbing the inner peripheral surface of the container part 20 with a brush. At this time, the concave portion 24 has a circular bottom portion 25 and an inward peripheral wall portion 26 surrounding the bottom portion 25, and the inner peripheral surface of the small diameter changing portion 26b is convex outward. Since the curved surface is drawn and the shape reaches the outer peripheral edge of the bottom 25 while gradually narrowing from the inner peripheral surface of the lower end portion of the same diameter portion 26a, the concave portion 24 can be easily washed with a brush or running water. . In addition, about the outer periphery of the container part 20, the cover part 12, etc., it can be wash | cleaned by the method similar to the general pot 10. FIG.

以上のように構成されたポット１０によると、抽出網３０の一方側（下側）の開口部は、凹部２４と上方開口部と最底部２５との間に位置した状態で凹部２４に嵌め込まれて容器部２０に装着されるため、当該抽出網３０を容器部２０から容易に取外しまた装着することができる。また、被抽出物を抽出網３０内に投入した後、飲料を注ぐ際には、抽出網３０内に投入された被抽出物の少なくとも一部は、抽出網３０の一方側（下側）の開口部と凹部２４との接触部分よりも底側で凹部２４内に貯まる。このため、被抽出物が抽出網３０と凹部２４との接触部分を通って漏出し難い。特に、細かい被抽出物は、凹部２４の底の下方に貯まる傾向にあるため、飲料を注ぐ際に、抽出網３０の一方側（下側）の開口部との接触部分を通って漏出し難い。 According to the pot 10 configured as described above, the opening on one side (lower side) of the extraction net 30 is fitted into the recess 24 in a state of being positioned between the recess 24, the upper opening, and the bottom 25. Therefore, the extraction net 30 can be easily detached from the container part 20 and attached. In addition, when a beverage is poured after the extract is put into the extraction net 30, at least a part of the extract put into the extraction net 30 is on one side (lower side) of the extraction net 30. It accumulates in the recess 24 on the bottom side of the contact portion between the opening and the recess 24. For this reason, it is difficult for the substance to be extracted to leak through the contact portion between the extraction net 30 and the recess 24. In particular, since a fine extract tends to be stored below the bottom of the recess 24, it is difficult to leak through a contact portion with an opening on one side (lower side) of the extraction net 30 when pouring a beverage. .

しかも、凹部２４は、同径部分２６ａの下端部内周面から徐々に狭まりつつ最底部２５の外周縁部に至る形状であるため、凹部２４の底に貯まった被抽出物を洗浄し易い。 And since the recessed part 24 is the shape which reaches the outer-periphery edge part of the bottom-most part 25, narrowing gradually from the inner peripheral surface of the lower end part of the same diameter part 26a, it is easy to wash | clean the to-be-extracted substance accumulated on the bottom of the recessed part 24.

また、抽出網３０の一方側（下側）の開口部を、凹部２４の同径部分２６ａの任意の位置に嵌め込むことができるため、抽出網３０の高さ方向に関しては、抽出網３０の位置決め精度は低くてもよい。このため、抽出網３０の装着を容易に行える。 Moreover, since the opening part of the one side (lower side) of the extraction net | network 30 can be engage | inserted in the arbitrary positions of the same diameter part 26a of the recessed part 24, about the height direction of the extraction net | network 30, The positioning accuracy may be low. For this reason, the extraction network 30 can be easily attached.

また、凹部２４は、同径部分２６ａの下端部から最底部２５に向けて、内径が順次小さくなるように形成された細径変化部分２６ｂを有しているため、抽出網３０の一方側（下側）の開口部を凹部２４の細径変化部分２６ｂに嵌め込んでいくと、抽出網３０の一方側（下側）の開口部が凹部２４の内周面により強く押付けられ、それらの隙間がより小さくなる。これにより、抽出網３０内からの被抽出物の漏出をより確実に抑制できる。 Moreover, since the recessed part 24 has the small diameter change part 26b formed so that an internal diameter may become small gradually toward the bottom part 25 from the lower end part of the same diameter part 26a, one side ( When the opening on the lower side is fitted into the small diameter changing portion 26b of the recess 24, the opening on one side (the lower side) of the extraction mesh 30 is strongly pressed by the inner peripheral surface of the recess 24, and the gap between them. Becomes smaller. Thereby, the leakage of the to-be-extracted object from the inside of the extraction net | network 30 can be suppressed more reliably.

また、抽出網３０の一方側（下側）の開口部に弾性環状部材３８が装着されているため、この弾性環状部材３８を凹部２４の内周面に密着させることができる。これにより、抽出網３０の一方側（下側）の開口部と凹部との隙間をより確実に小さくして、抽出網３０内からの被抽出物の漏出をより確実に抑制できる。 In addition, since the elastic annular member 38 is attached to the opening on one side (lower side) of the extraction net 30, the elastic annular member 38 can be brought into close contact with the inner peripheral surface of the recess 24. Thereby, the clearance gap between the opening part and the recessed part of the one side (lower side) of the extraction net | network 30 can be made small more reliably, and the leakage of the to-be-extracted substance from the inside of the extraction net | network 30 can be suppressed more reliably.

また、抽出網３０の一方側（下側）の開口部及び他方側（上側）の開口部につば部３６ａ、３４ａが形成されているため、このつば部３６ａ、３４ａによって、抽出網３０の一方側（下側）の開口部及び他方側（上側）の開口部の変形を抑制できる。特に、抽出網３０の一方側（下側）の開口部の変形を抑制することによって、抽出網３０の一方側（下側）の開口部の外周全体を、ぴったりと凹部２４の内周面に嵌め込む状態を維持することができる。これにより、抽出網３０の一方側（下側）の開口部と凹部２４との隙間をより確実に小さくして、抽出網３０内からの被抽出物の漏出をより確実に抑制できる。 Further, since the flange portions 36a and 34a are formed in the opening portion on one side (lower side) and the opening portion on the other side (upper side) of the extraction net 30, one of the extraction nets 30 is formed by the flange portions 36a and 34a. Deformation of the opening on the side (lower side) and the opening on the other side (upper side) can be suppressed. In particular, by suppressing the deformation of the opening on one side (lower side) of the extraction net 30, the entire outer periphery of the opening on one side (lower side) of the extraction net 30 is exactly fitted to the inner peripheral surface of the recess 24. The state to be fitted can be maintained. Thereby, the clearance gap between the opening part of the one side (lower side) of the extraction net | network 30 and the recessed part 24 can be made small more reliably, and the leakage of the to-be-extracted substance from the inside of the extraction net | network 30 can be suppressed more reliably.

また、蓋部１２が抽出網３０を押え込んでいるため、抽出網３０の一方側（下側）の開口部と周壁部２６との嵌まり合い関係をより確実に実現或は維持することができる。これにより、その間を通った被抽出物の通過をより確実に抑制することができる。 Further, since the lid 12 holds the extraction mesh 30 in, the fitting relationship between the opening portion on one side (lower side) of the extraction mesh 30 and the peripheral wall portion 26 can be realized or maintained more reliably. it can. Thereby, passage of the to-be-extracted object which passed through it can be suppressed more reliably.

｛変形例｝
なお、上記実施形態では、抽出網３０がその軸方向に沿って同径である筒状である例で説明したが、必ずしもその必要はない。例えば、抽出網は、軸方向一方側（ここでは下方側）に向けて順次縮径する筒状に形成されていてもよい。 {Modifications}
In the above-described embodiment, the extraction net 30 has been described as an example of a cylindrical shape having the same diameter along the axial direction, but this is not necessarily required. For example, the extraction net may be formed in a cylindrical shape that sequentially decreases in diameter toward one side in the axial direction (here, the lower side).

また、被抽出物としては、日本茶、紅茶、中国茶等の各種茶葉、その他、コーヒー等を想定することができる。すなわち、本実施形態は、各種被抽出物から、お湯、お水等の液体を溶媒として、コーヒー成分等の各種飲料成分を抽出するものに適用可能である。 Moreover, as an extract, various tea leaves, such as Japanese tea, black tea, and Chinese tea, other coffee etc. can be assumed. That is, this embodiment is applicable to what extracts various drink components, such as a coffee component, using various liquids, such as hot water and water, as a solvent.

抽出網３０の網目の大きさは、それらの被抽出物の大きさに応じて適宜設定される。抽出網３０は、日本茶用、紅茶用、コーヒー用等、被抽出物の種類に応じて別々のものを準備しておくことが好ましい。これにより、別種の抽出物のにおいが、他の抽出物を抽出する際に、移ってしまうことを抑制することができる。 The size of the mesh of the extraction net 30 is appropriately set according to the size of the extraction object. It is preferable to prepare different extraction nets 30 for Japanese tea, black tea, coffee, etc., depending on the type of extract. Thereby, it can suppress that the smell of another kind of extract transfers, when extracting another extract.

また、抽出容器、蓋部は、ガラス、陶器、漆器、金属製等によって製造することができる。 Moreover, an extraction container and a cover part can be manufactured with glass, ceramics, lacquerware, metal, etc.
