Description

The present invention relates to an electronic tag used in automatic recognition technology using radio.

As part of product sales promotion activities, campaigns using campaign labels are being implemented for various products.

As campaign labels attached to products sold at retail stores, etc., two-layer labels in which two label base materials are releasably bonded together are widely used (for example, Patent Document 1). For campaign labels using two-layer labels, the application information necessary for campaign application is printed on the surface of the lower layer label base material, and by flipping (peeling off) the upper layer label base material, the application information necessary for campaign application is printed on the surface of the lower layer label base material. You can see the application information printed on the .

Information that shows the winning result on the spot (for example, "win" or "miss") may be used as application information, but in large-scale campaigns, it is necessary to conduct marketing activities to consumers who applied for the campaign. , a code input to a campaign site on the Internet is used as application information (for example, Patent Document 2).

On the other hand, it has been considered for some time that consumers can manage the products they consume at home by attaching electronic tag labels to them. For example, government agencies are considering a supply chain information sharing system that uses electronic tags affixed to products to share and utilize various product-related information throughout the supplier chain, with the aim of improving supply chain operational efficiency. ing.

However, conventional electronic tag labels used in product management systems are not configured to be used for both product management and campaign purposes.

Therefore, an object of the present invention is to provide an electronic tag label that can be used for both product management and campaign purposes.

The present invention, which solves the above-mentioned problems, has an upper layer base material that becomes an upper layer label base material and a lower layer base material that becomes a lower layer label base material, and the upper layer base material and the lower layer base material are bonded together by a pseudo adhesive layer. An optical code layer is provided on the front side of the lower base material to display an optical code that encodes the application information necessary for applying for the campaign, and an electronic label that stores the code used for product management is provided. The electronic tag label is characterized in that a tag is provided on the back side of the lower base material.

In order to be usable for both product management and campaign purposes, the electronic tag label according to the present invention has an optical code layer that displays an optical code used in campaigns and an electronic tag used in product management provided on the lower base material of the electronic tag label. ing.

FIG. 2 is an external view of an electronic tag label according to the present embodiment. FIG. 2 is a diagram illustrating the layer structure of the electronic tag label according to the present embodiment. FIG. 2 is a diagram illustrating an example of an electronic tag.

From here, the embodiments for carrying out the present invention will be described in detail. Note that this explanation is provided to facilitate understanding of the present invention, and the present invention is not limited to what will be described below. Further, unless otherwise specified, the drawings are schematic diagrams drawn to facilitate understanding of the present invention.

FIG. 1 is an external view of an electronic tag label 1 according to this embodiment. The electronic tag label 1 of this embodiment has an upper layer base material 2 that is an upper layer label base material and a lower layer base material 3 that is a lower layer label base material, and the upper layer base material 2 and the lower layer base material 3 are adhered to each other in a peelable manner. It is in the form of a two-layer label.

As shown in FIG. 1, the electronic tag label 1 according to the present embodiment is an electronic tag that stores an EPC (Electronic Product Code), which is a code used for product management, so that it can be used for both product management and campaign purposes. 5 is provided on the back side of the lower layer base material 3, and an optical code layer 4 for displaying an optical code (here, a two-dimensional barcode) that encodes the application information necessary for applying for the campaign is provided on the front side of the lower layer base material 3. There is.

The layer structure of the electronic tag label 1 according to this embodiment will be explained. FIG. 2 is a diagram illustrating the layer structure of the electronic tag label 1 according to this embodiment.

The layer structure of the electronic tag label 1 is, in order from the top, the top surface pattern layer 70, the top base material 2, the top back pattern layer 71, the pseudo adhesive layer 60, the optical code layer 4, the bottom surface pattern layer 72, the bottom base material 3, It has a structure in which a first adhesive layer 61, an electronic tag 5, a second adhesive layer 62, and a release paper 8 are laminated in this order.

The upper surface pattern layer 70 is a layer provided on the surface of the upper base material 2 by printing. The pattern represented by the upper surface pattern layer 70 may include a pattern (such as a campaign pattern) that enhances the eye-catching effect of the electronic tag label 1 or a document that causes the upper layer base material 2 to be peeled off (for example, "Turn over the first label"). It will be included.

The upper layer base material 2 is a sheet-like base material that becomes the first layer of the electronic tag label 1. Although various plastic materials can be used for the upper layer base material 2, it is preferable to use PET (polyethylene terephthalate) with a thickness of 50 μm for the upper layer base material 2. Note that the upper layer base material 2 can also be made of a plurality of materials bonded together.

The upper back surface pattern layer 71 is a layer provided on the back surface of the upper layer base material 2 by printing. The picture represented by the upper back picture layer 71 generally includes a detailed explanation of the campaign corresponding to the electronic tag label 1. When a highly transparent material is used for the upper base material 2, it is necessary to provide the upper back pattern layer 71 with hiding properties in order to make the optical code layer 4 invisible from the surface. When used as material 2, it is not necessarily necessary to provide the upper back pattern layer 71.

The pseudo adhesive layer 60 is a layer that adheres the upper layer base material 2 and the lower layer base material 3 in a peelable state. The pseudo-adhesive layer 60 may be formed using known techniques, and the content of the pseudo-adhesive layer 60 is not limited, but for example, thermoplastic resin such as polyethylene or polypropylene, a pressure bonding adhesive, or the like can be used. A pseudo adhesive layer 60 will be formed on the back surface of the upper layer base material 2, but in order to prevent the peeled upper layer base material 2 from separating from the lower layer base material 3, one side of the upper layer base material 2 (the upper side in FIG. 1) It is preferable to provide an adhesive layer other than the pseudo-adhesive layer 60 on the back surface.

The lower surface pattern layer 72 is a layer provided on the surface of the lower substrate 3 by printing, and the optical code layer 4 is a layer provided on the lower surface pattern layer 72 by printing.

When a highly transparent material is used for the lower base material 3, it is desirable to make the electronic tag 5 provided on the back side of the lower base material 3 invisible from the surface of the lower base material 3. Therefore, when a highly transparent material is used for the lower base material 3, it is necessary to provide the lower surface pattern layer 72 with concealment properties. Note that the pattern displayed on the lower surface pattern layer 72 may include a document (for example, "Read the barcode with your smartphone") that urges the optical code layer 4 to be read.

The picture displayed in the optical code layer 4 is an optical code in which at least campaign application information is encoded. Campaign application information generally includes a code to be entered into a campaign site on the Internet. From the perspective of preventing unauthorized use of application information, it is preferable that the code included in application information be a random number rather than a serial number. Furthermore, the URL of a campaign site on the Internet can also be included in the application information. Note that the optical code refers to a pattern that optically records data by printing. The type of optical code displayed in the optical code layer 4 is arbitrary. The optical code displayed on the optical code layer 4 may be a one-dimensional barcode, but it is preferable to use a two-dimensional barcode as the optical code displayed on the optical code layer 4, which can store more information than a one-dimensional barcode. It is.

The lower layer base material 3 is a sheet-like base material that becomes the second layer of the electronic tag label 1. Similar to the upper layer base material 2, various plastic materials can be used for the lower layer base material 3, and it is preferable to use PET (polyethylene terephthalate) with a thickness of 50 μm for the lower layer base material 3. It is also possible to use a material for the lower layer base material 3.

The size of the lower layer base material 3 may be the same as the size of the upper layer base material 2, but may be larger than the size of the upper layer base material 2. In FIG. 1, the size of the lower layer base material 3 in the vertical direction is made larger than the upper layer base material 2, and the upper layer base material 2 and the lower layer base material 3 are attached so that the lower side of the lower layer base material 3 protrudes from the upper layer base material 2. It's matching.

The first adhesive layer 61 is a layer provided on the back surface of the lower base material 3. The first adhesive layer 61 may be formed using known techniques, and the content of the first adhesive layer 61 is not limited, but may be made of known materials such as rubber, EVA, olefin, polyester, polyamide, urethane, etc. Adhesives and adhesives can be used.

The electronic tag 5 is attached to the back side of the lower base material 3 using the first adhesive layer 61. The form of the electronic tag 5 is arbitrary. The form of the electronic tag 5 may be an inlay consisting only of an antenna 50 and an IC chip 51 connected thereto, or may be a form in which the inlay is mounted on a film.

FIG. 3 is a diagram illustrating an example of the electronic tag 5. The frequency band used by the electronic tag 5 shown in FIG. 3 is the UHF band, and the antenna 50 of the electronic tag 5 is a loop-shaped impedance matching circuit 501 connected to an IC chip 51 that stores at least the EPC required for product management. It has a dipole antenna structure in which linear elements 500 bent in a meander shape are connected to both sides of the antenna. Note that the reason why the linear element 500 is bent into a meander shape is to make the size of the antenna 50 compact.

The second adhesive layer 62 is a layer provided under the electronic tag 5. In the electronic tag label 1 of this embodiment, the electronic tag 5 is sandwiched between the first adhesive layer 61 and the second adhesive layer 62. As a result, it is protected by the first adhesive layer 61 and the second adhesive layer 62.

The second adhesive layer 62 is preferably made of a material suitable for the product to which the electronic tag label 1 is attached. If paper peeling when peeling off the electronic tag label 1 is not a problem, similar to the first adhesive layer 61, for example, hot melt adhesive, rubber adhesive, EVA adhesive, olefin adhesive, polyester adhesive, polyamide adhesive, urethane adhesive, etc. Any known adhesive or adhesive can be used for the second adhesive layer 62. If paper peeling occurs when the electronic tag label 1 is peeled off, such as when attaching the electronic tag label 1 to a cosmetic box of a product, a removable adhesive is used for the second adhesive layer 62.

The release paper 8 is the lowest layer of the electronic tag label 1 and is the layer that is peeled off when the electronic tag label 1 is attached. The release paper 8 is paper whose surface has been subjected to a release process. For example, paper whose surface is coated with silicone resin can be used as the release paper 8.

It may seem that there is no usefulness in providing one electronic tag label 1 with an electronic tag 5 that stores an EPC used for product management and an optical code layer 4 that represents an optical code that encodes application information. By providing the tag 5 and the optical code layer 4 on one electronic tag label 1, unauthorized use of application information can be prevented.

In the electronic tag label 1 of this embodiment, the electronic tag 5 used for product management and the optical code layer 4 for displaying the optical code used in the campaign are provided on the lower base material 3 of the electronic tag label 1, so a random number is included in the application information. Even if the optical code is different for each included electronic tag label, EPC and application information can be linked.

For example, if the random number included in the application information is EPC, it becomes easier to link the EPC and application information. In this case, an optical code layer 4 representing an optical code encoded with EPC is formed (printed) on the lower base material 3 in advance using an inkjet printer or the like, and an electronic tag 5 is laminated on the back surface of the lower base material 3. At this time, if the EPC is read from the optical code appearing on the optical code layer 4 and written on the electronic tag 5 laminated on the back side of the lower base material 3, the EPC used for product management and the code included in the application information can be the same. Can be done. Note that if the application information is stored in association with the EPC in the manufacturing process of the electronic tag label 1, the EPC and the application information can be linked using other methods.

If the EPC and application information are linked, for example, by using a system that manages products using electronic tags 5, such as a supply chain information sharing system, it can be linked to the application information entered on the campaign site. You can check whether a product compatible with EPC has been sold at a retail store. If the campaign site treats only application information linked to the EPC of products sold at retail stores as valid, it will prevent unauthorized use of application information, such as the use of electronic tag labels 1 that have been illegally removed from products. It can be prevented.
