Description

The present invention relates to a paperboard paper container on which an RFID (radio frequency identifier) chip is arranged.

RFID exchanges information from RF tags (also called IC tags, electronic tags, etc.) in which ID information is embedded by short-distance (several cm to several m depending on the frequency band) wireless communication using electromagnetic fields and radio waves. It is a technology. As a result, by using an RFID reader / writer, the data of the electronic tag can be read and written in a non-contact state with the electronic tag. Since RFID has a larger amount of writable data than barcodes and the like, it can be used for product management and cash register processing, especially by attaching it to products, and batch processing of products is expected in the future. Such batch processing can be expected to reduce food loss by RFID-compatible self-checkout, automatic inventory processing using the shelf itself as an RFID reader, shoplifting prevention, and expiration date management.

Such an electronic tag will be attached to a product, but since the electronic tag can be recognized without being visually recognized from the outside, it is arranged inside a package that is not visible from the outside, for example, a paper container. As a result, the appearance of the product is not changed.

For paper containers such as product packaging and packaging, an exterior with metallic luster is adopted to improve the appearance quality, especially to express luxury and luxury. In general, aluminum is often vapor-deposited on the exterior that exhibits a metallic color or metallic luster. However, since the aluminum vapor deposition layer is a good conductor and blocks electromagnetic waves, it cannot be used for the exterior of products using RFID.

Correspondingly, as a material having a metallic luster but not blocking radio waves, a material obtained by depositing tin or a tin alloy or tin or a tin alloy on a base film is known (see Patent Documents 1 and 2). .. When a thin-film vapor-deposited layer made of tin or a tin alloy or the like is formed on the base material, the surface of the base material has a metallic luster and the thin-film vapor-deposited layer has an insulating property. It can be used and can be used for food packaging and apparel packaging materials.

Further, assuming that the electronic tag itself has a metallic color and metallic luster, a coil-on-chip (registered trademark) having a structure in which a coil is formed on a semiconductor chip provided with a metal layer is fixed to the base film surface, and the coil thereof. On-chip (registered trademark) and base film surfaces include those in which a surface substrate made of a plastic film or a paper substrate having an insulating metallic luster layer by vapor deposition is laminated on the outer surface (see Patent Document 3).

A paper container according to a mode for carrying out the present invention will be described. The paper container according to the present embodiment is a paper container formed of processed paper to protect products, and the processed paper is arranged on a base material made of paperboard and the surface of the base material so that electromagnetic waves can be transmitted. The paper container is provided with a tin or tin alloy vapor deposition layer, and an RFID chip that identifies the product is arranged on the processed paper. Further, the tag according to the present embodiment is a tag attached to a product, and the processed paper is a base material made of paperboard and tin or tin which is arranged on the surface of the base material and is formed so that electromagnetic waves can be transmitted. A vapor-deposited layer of an alloy is provided, and the processed paper is provided with an RFID chip that identifies the product.

First, the processed paper for forming the paper container according to the embodiment and the RFID tag will be described. FIG. 1 shows a configuration of a paper container according to an embodiment of the present invention, (a) is a cross-sectional view showing a processed paper for producing the paper container, and (b) shows an RFID chip arranged in the paper container. It is a cross-sectional view.

As shown in FIG. 1A, the processed paper 10 has a tin-deposited layer 13 formed on one side (upper side in the drawing) of the paperboard 11 which is a base material. The tin-deposited layer 13 is formed on a PET (polyethylene terephthalate) film 14, and an anchor coating agent layer 15 is formed on the PET film 14. The anchor coating agent layer can not be formed on the PET film 14. Further, after arranging the tin-deposited layer 13 and the PET film 14 on the paperboard 11, the PET film 14 can be peeled off to form only the tin-deposited layer 13 on the paperboard 11. That is, when the tin-deposited layer is formed on the paperboard, the PET film on which the tin-deposited layer is formed can be bonded, and only the tin-deposited layer can be formed on the paperboard.

The paperboard 11 is a paperboard for a paper container, and for example, a white paperboard is used. As the paperboard, one having oil resistance and water resistance can be used. As the paperboard, for example, a paperboard having a weight of 100 to 600 g / m2 is generally used. In this embodiment, for example, 310 g / m2 of paperboard is used. Therefore, the processed paper 10 is not a so-called soft package, and can maintain its shape without arranging members inside.

The tin-deposited layer 13 is pre-deposited on the PET film 14. An anchor coating agent layer 15 is formed on the surface of the PET film 14 opposite to the tin-deposited layer 13 forming side. The processed paper 10 is formed by joining the PET film 14 on which the tin-deposited layer 13 is formed to the paperboard 11 with the adhesive layer 12.

The tin-deposited layer 13 is formed on the PET film 14 by a vacuum vapor deposition method, a sputtering method, or an ion plating method. A tin alloy can be used instead of tin. In the thin-film deposition layer of tin or tin alloy, tin is not a uniform thickness but is distributed in the sea-island structure, exhibits insulating properties, and transmits radio waves. The thickness dimension of the tin-deposited layer 13 can be 5 nm to 100 nm, for example, 30 nm to 50 nm. As for the insulating property, it has been confirmed that it does not spark by applying a charge of 15 kv as an electrostatic resistance. Increasing the thickness increases the metallic color and metallic luster, but reduces the permeability of electromagnetic waves and the like.

The tin-deposited layer shall be determined by conducting experiments on the thickness and vapor deposition conditions suitable for the frequency of radio waves used in RFID. Further, the purity of tin does not necessarily have to be 100%, and impurities may be present.
In addition, tin alloys can also be used.

The PET film 14 has a thickness of, for example, 12 μm. Instead of the PET film, a plastic film such as PE (polyethylene resin: polyethylene), PP (polypropylene resin: polypropylene), polyamide synthetic resin (nylon), PC (Polycarbonate), etc. can be used.

The anchor coating agent layer 15 is applied to improve the adhesion between the PET film 14 and the ink. The positions of the PET film 14 and the tin-deposited layer 13 can be exchanged.

In order to create a paper container from the processed paper 10 as described above, the surface of the processed paper 10, that is, the PET film 14 side is printed with the necessary printing on the package, and the package is cut out and assembled into the developed figure of the package to be created. At this time, the RFID tag 20 is arranged on the processed paper 10 forming the paper container. When the RFID tag 20 is arranged in a state where the processed paper is assembled and is not visible from the outside, it is possible to prevent the RFID tag 20 from being removed from the outside.

The RFID tag 20 can be attached to any part of the paper container, for example, the body plate portion, the top plate portion, and the front side or the back side of the bottom portion. The location where the RFID tag 20 is attached is determined by the user of the paper container. Considering productivity, it is preferable that the RFID tag 20 is continuously attached by an auto labeler. The RFID tag 20 can be manually attached to the paper container by an operator instead of a machine.

Next, the schematic configuration of the RFID tag 20 will be described. As shown in FIG. 1B, the RFID tag 20 attaches the RFID chip 21 to which the antenna 22 is connected to the base material 24 with glue 23. The base material 24 is a paper or plastic film, and a pattern 25 is printed on the surface thereof as needed. Then, glue 26 is applied so as to cover the RFID chip 21 and the antenna 22, and the release paper 27 is attached.

To attach the RFID tag 20 to a paper container made of processed paper 10, the release paper is peeled off from the RFID tag 20 and attached with glue 26.

The paper container is manufactured using the processed paper 10 as the base paper in the order of printing necessary items, punching the shape of the developed view of the paper container, attaching the RFID tag 20, and assembling the paper container, and further arranging the products.
The RFID tag 20 can be attached to the paper container after the product is filled.

Here, the RFID tag 20 can be selected as needed and has various sizes. If you want to communicate in a short distance, the antenna is small and the size of the RFID tag 20 is small. On the other hand, when communication is desired over a long distance, the antenna becomes large and the size of the RFID tag 20 becomes large. Selected according to the user's request.

The RFID tag 20 has uses for distribution and for authenticity determination. For distribution, it is used for checking at the time of arrival, inventory management, shipping, etc. At this time, a plurality of RFID tags 20 attached to paper containers of a large number of products can be collectively read by a reader. On the other hand, for authenticity, the reader checks the products individually, that is, individually.

Hereinafter, various paper containers according to the embodiment will be described. Paper containers include packages having a closed structure that surrounds the entire circumference of the product, trays and mounts that have an open structure in which the paper container covers a part of the product, adheres to the product, or is placed close to the product. ..
