Description

  The present invention relates to a container and a method for determining an open state of a container.

  Conventionally, there is a case where a container having an upper and lower lid made of a material such as PET and bonded with hot melt or the like is shipped. However, there are cases where counterfeit products with the upper lid removed and the contents of the container replaced are on the market, and in order to prevent such a situation, a container equipped with an IC chip that can confirm the opening of the container is known. (See WO2005 / 026014A1).

  WO2005 / 026014A1 describes a container in which an antenna circuit provided externally to an IC chip is formed across a container body and a sealing portion.

  In the container of WO2005 / 026014, since the antenna circuit is cut when the sealed portion is opened, sufficient reception and transmission of radio waves cannot be performed, and the opening of the container can be confirmed. However, in order to prevent the third party from breaking the antenna circuit, it is conceivable to try to replace the contents of the container by opening the container avoiding the antenna circuit, etc. It may not be.

  The present invention has been made in view of such technical problems, and it is possible to prevent generation of a counterfeit product and to detect an unauthorized opening of a container by a third party more reliably. An object is to provide a method for determining an opened state.

  According to an aspect of the present invention, a first RFID inlet, a second RFID inlet stacked on the first RFID inlet, a cover portion provided to cover the second RFID inlet, A first adhesive layer provided between the second RFID inlet and the cover portion, and the cover portion adhered to the first adhesive layer is separated from the second RFID inlet. In this case, a container for breaking the antenna provided in the second RFID inlet is provided.

  According to another aspect of the present invention, of the antenna provided in the first RFID inlet and the antenna provided in the second RFID inlet, the antenna provided in the second RFID inlet is When the container is opened when it is broken based on the separation of the cover portion provided to cover the second RFID inlet and the presence of the IC chip connected to the second RFID inlet cannot be detected. A method for determining an open state of a container to be determined is provided.

  According to the said aspect, generation | occurrence | production of a counterfeit product can be prevented and the unauthorized opening of a container by a third party can be detected more reliably.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a perspective view of a container 10 according to an embodiment of the present invention.

  The container 10 is distributed in the form of a pack containing the contents, and the contents can be taken out by removing the cover part 13. In the container 10, for example, a high-quality product such as a verified diamond is stored. Further, the container 10 includes an RFID inlet with an IC chip 17 attached thereto, and can determine whether or not the container is opened by transmitting and receiving radio waves with an external antenna. In addition, in the container 10, it is desirable to use a batch reading technique such as PJM (Phase Jitter Modulation) so that the presence / absence of opening can be determined in a large amount and at high speed.

  Hereinafter, the configuration of the container 10 will be described in detail with reference to FIGS. 2 and 3.

 FIG. 2 is a schematic sectional view taken along line II-II passing through the IC chip 17 in FIG. FIG. 3 is a schematic top view of the second RFID inlet 12 as viewed from the cover portion 13 side.

  As shown in FIG. 2, the container 10 of the present embodiment covers the first RFID inlet 11, the second RFID inlet 12 stacked on the first RFID inlet 11, and the second RFID inlet 12. Between the first RFID inlet 11 and the second RFID inlet 12, the first adhesive layer 14 provided between the second RFID inlet 12 and the cover portion 13, and the first RFID inlet 11 and the second RFID inlet 12. The second adhesive layer 15 is provided. In FIG. 2, the RFID inlets 11 and 12, the first adhesive layer 14, and the like are drawn thicker than actual for easy understanding.

  The first RFID inlet 11 includes an inlet base material 16, an IC chip 17, and an antenna 18.

  The inlet base 16 is configured as, for example, polyethylene terephthalate or a laminated film thereof. The thickness of the inlet base material 16 is, for example, 100 μm.

  The IC chip 17 is provided on the surface of the inlet base material 16 by being connected to the antenna 18. The IC chip 17 has a protruding amount of about 150 μm to 160 μm from the inlet base material 16 in a state of being provided on the inlet base material 16.

  The antenna 18 transmits and receives radio waves in a predetermined frequency band such as an HF band (3 MHz to 30 MHz, particularly around 13.56 MHz). The antenna 18 is generated from a predetermined metal film (for example, a metal film such as copper or aluminum), and is connected to the IC chip 17 by baking bonding using, for example, an anisotropic conductive paste or a conductive film. Therefore, data transmitted / received by the antenna 18 is processed by the IC chip 17. Note that the thickness of the antenna 18 is, for example, several μm to several tens of μm.

  The first RFID inlet 11 is molded integrally with the resin 19. The first RFID inlet 11 is sealed in the resin 19 by being molded integrally. As the resin 19, for example, polyvinyl chloride (PVC) resin or glycol-modified polyethylene terephthalate (PET-G) resin can be used. The molding method is, for example, thermoforming. By sealing the first RFID inlet 11 in the resin 19 by thermoforming, the color of the resin changes from transparent to white, so that the first RFID inlet 11 cannot be visually recognized from the outside. Therefore, generation | occurrence | production of a counterfeit can be prevented. In addition, the thickness of the 1st RFID inlet 11 shape | molded integrally with resin 19 is 0.5 micrometer-0.75 micrometer, for example.

  The second RFID inlet 12 includes an inlet base material 16, an IC chip 17, and an antenna 18. Since the inlet base material 16, the IC chip 17, and the antenna 18 are the same as those of the first RFID inlet 11, description thereof will be omitted.

  As shown in FIG. 3, the second RFID inlet 12 is provided with a notch 20 for breaking the antenna 18 when the cover portion 13 is peeled off. The notch 20 includes two slits 20a extending from the outer edge of the antenna 18 toward the outer peripheral direction of the inlet base material 16 of the second RFID inlet 12, and the two slits on the opposite side of the outer edge of the antenna 18. The slit 20b connects the ends. The effect of breaking the antenna 18 will be described in detail later. The notch 20 may be provided so as to straddle the installation area of the antenna 18. The cut 20 has, for example, a width of about 3.00 mm and a length of about 10.0 mm.

  Returning to FIG. 2, the first adhesive layer 14 is provided by hot melt welding or the like. As the hot melt adhesive, for example, an adhesive having ethylene vinyl acetate resin, polyolefin resin, or the like as a main component, solid at room temperature, melted by heating, and thermoplasticity can be used.

  The 2nd adhesion layer 15 has the pasting part 21 in which an adhesive exists, and the pasteless part 22 (hatching part of FIG. 3) in which an adhesive does not exist. The first RFID inlet 11 and the second RFID inlet 12 are bonded by the glued portion 21. For example, the non-glue 22 has a width of about 4.00 mm and a length of about 15.0 mm. The pressure-sensitive adhesive used for the second pressure-sensitive adhesive layer 15 may be any pressure-sensitive adhesive having a strength equal to or higher than that of the above-described hot melt welding.

  The cover portion 13 has a convex portion 13 a formed at the center thereof, and is provided so as to cover the second RFID inlet 12. The shape and material of the cover part 13 are not particularly limited as long as the contents of the container 10 can be sealed.

  FIG. 4 is a schematic diagram showing how the antenna 18 is broken. FIG. 5 is a schematic diagram illustrating a state in which the cut 20 is pulled toward the cover unit 13 when the cover unit 13 is peeled off.

  In the present embodiment, the strength of the first adhesive layer 14 is lower than the strength of the second adhesive layer 15. This is because when the cover unit 13 is separated from the second RFID inlet 12, the antenna 18 provided at a position facing the non-glue part 22 is attached to the cover unit 13 side and faces the glued part 21. This is because the antenna 18 provided at the position is held on the surface of the second RFID inlet 12.

  As a result, as shown in FIGS. 4 and 5, when the cover portion 13 is peeled in the direction of the arrow, the inner portion of the cut 20 is attached to the cover portion 13 side and pulled by the first adhesive layer 14. In addition, an adhesive-free portion 22 of the second adhesive layer 15 is provided below the cut 20. Due to the presence of the adhesiveless portion 22, the inner portion of the cut 20 is pulled to the cover portion 13 side without being attached to the first RFID inlet 11 side. And this tensile force acts in the direction orthogonal to the antenna 18, and the antenna 18 breaks.

  In this way, the notch 20 is formed in the second RFID inlet 12 and the adhesiveless portion 22 is formed on the lower side thereof, whereby the cover portion 13 adhered to the first adhesive layer 14 is removed from the second RFID inlet. When separating from the antenna 12, the antenna 18 provided in the second RFID inlet 12 can be broken.

  The location and number of the cuts 20 are not particularly limited. For example, when the cuts 20 are provided at the corners of the second RFID inlet 12, the antenna 18 is immediately removed when the cover 13 is peeled off. Is preferable because it breaks. Furthermore, when the notches 20 are provided in the four corners of the second RFID inlet 12, it is more preferable because the antenna 18 is smoothly broken even if the cover portion 13 is peeled from any of the four corners. In addition to the four corners, it is preferable that the notch 20 is provided in the center of each side of the second RFID inlet 12 because the antenna 18 is more reliably broken than in the case of the four corners.

  In addition, as shown in FIG. 2, the IC chip 17 provided in the first RFID inlet 11 and the IC chip 17 provided in the second RFID inlet 12 are provided so as to face in opposite directions. . That is, the first RFID inlet 11 is in a state where the second RFID inlet 12 is turned over. In this state, the antenna 18 of the first RFID inlet 11 and the antenna 18 of the second RFID inlet 12 do not completely overlap each other.

  That is, in the present embodiment, when the first RFID inlet 11 and the second RFID inlet 12 are overlapped, the antenna 18 of the first RFID inlet 11 and the antenna 18 of the second RFID inlet 12 are mutually connected. The position is shifted. In this way, by shifting the position of the antenna 18 from each other, it is possible to eliminate the risk of being unable to read due to mutual interference, and high-speed data transfer can be realized based on the batch reading technique in the high-speed mass transport described above.

  Next, a modified example of the aspect of the cut 20 will be described.

  FIG. 6 is a schematic top view of the second RFID inlet 12 showing a modification of the form of the notch 20 as viewed from the cover portion 13 side.

  As shown in the modification of FIG. 6, the cut 20 is provided so as to extend from the outer edge of the antenna 18 to the outer periphery in the outer peripheral direction of the second RFID inlet 12. Even with such a cut 20, the antenna 18 can be broken. In addition, since the cut 20 of the modification is provided so as to contact the antenna 18, the antenna 18 is more easily broken.

  Moreover, the non-glue part 22 formed in the 2nd adhesion layer 15 provided in the lower side of the 2nd RFID inlet 12 is provided in the position facing the area | region enclosed by the notch | incision 20, for example. As a result, the notch 20 is pulled to the cover (not shown) side without being attached to the second RFID inlet 12 side, so that the antenna 18 is more easily broken.

  According to the container 10 which concerns on this embodiment mentioned above, the following effects can be acquired.

  The container 10 according to this embodiment includes a first RFID inlet 11, a second RFID inlet 12 stacked on the first RFID inlet 11, and a cover portion provided to cover the second RFID inlet 12. 13, and a first adhesive layer 14 provided between the second RFID inlet 12 and the cover portion 13. And when separating the cover part 13 adhere | attached on the 1st adhesion layer 14 from the 2nd RFID inlet 12, the antenna 18 provided in the 2nd RFID inlet 12 is fractured | ruptured.

  In other words, in the present embodiment, the antenna 18 of the first RFID inlet 11 is left without being broken, and the antenna 18 of the second RFID inlet 12 is broken. As described above, when the antenna 18 of the second RFID inlet 12 is broken and the combination of the RFID inlets 11 and 12 is not established, the presence of the IC chip 17 connected to the second RFID inlet 12 can be detected. Since it disappears, it can confirm instantly that the container 10 was opened. As described above, when the cover portion 13 is peeled off, the antenna 18 of the second RFID inlet 12 is broken, so that an unauthorized opening of the container by a third party can be detected.

  In the present embodiment, in order to easily break the antenna 18 provided in the second RFID inlet 12, a cut 20 is provided in the second RFID inlet 12. By providing the cut 20, when the cover portion 13 is peeled off, the cut 20 is pulled toward the cover portion 13, and the antenna 18 breaks due to this tensile force acting.

  In addition, the container 10 according to the present embodiment has a second adhesive layer 15 provided between the first RFID inlet 11 and the second RFID inlet 12, and the second adhesive layer 15 includes In addition, there are provided an adhesive portion 21 and an adhesive-free portion 22 in which no adhesive is present, and a cut 20 is formed in the second RFID inlet 12 at a position facing the adhesive-free portion 22.

  As a result, when the cover part 13 adhered to the first adhesive layer 14 is separated from the second RFID inlet 12, the notch 20 is more reliably pulled toward the cover part 13 side, and the second RFID The antenna 18 provided in the inlet 12 can be broken more reliably.

  In the present embodiment, an adhesive is used in which the strength of the first adhesive layer 14 is lower than the strength of the second adhesive layer 15.

  Thereby, when the cover part 13 adhered to the first adhesive layer 14 is separated from the second RFID inlet 12, the antenna 18 provided in the second RFID inlet 12 is broken while the second The adhesive layer 15 can be prevented from peeling off.

  Next, an example of the method for determining the opened state of the container 10 described above will be described.

  For example, an opening state determination method for the container 10 in a state where one or a plurality of containers 10 of the present embodiment containing the contents are contained in the packing box and the lid of the packing box is sealed will be described.

  Whether or not a combination of two RFID inlets (first RFID inlet and second RFID inlet) is established by irradiating the packaging box with communication radio waves from the reader / writer antenna portion of the reader / writer outside the packaging box Based on the above, it is determined whether or not the container 10 has been opened.

  That is, among the antenna 18 provided in the first RFID inlet 11 and the antenna 18 provided in the second RFID inlet 12, the antenna 18 provided in the second RFID inlet 12 is connected to the second RFID inlet 12. When the presence of the IC chip 17 connected to the second RFID inlet 12 can no longer be detected, the container 10 is determined to have been opened. To do.

  Thus, based on whether or not the combination of the RFID inlets 11 and 12 is established, it is possible to instantaneously determine whether or not the container 10 has been opened.

  As mentioned above, although embodiment of this invention was described, the said embodiment showed only a part of application example of this invention, and is not the meaning which limits the technical scope of this invention to the specific example of said embodiment. . Further, the above embodiments can be arbitrarily combined.

  This application claims the priority based on Japanese Patent Application No. 2015-194890 for which it applied to the Japan Patent Office on September 30, 2015, and all the content of this application is integrated in this specification by reference.
