JP5204567B2 - RF-ID tag - Google Patents

Description

  The present invention relates to an RF-ID tag capable of writing and reading information in a non-contact state.

  Conventionally, in products that are displayed and sold in stores, tags with information about products such as product number, size, color, price, etc. are attached, and the information displayed on the tags is the consumer In addition, merchandise management is performed using information displayed on the tag on the store side. As tags attached to such products, there are those having the simplest structure, such as those displaying information on the attached products, and those displaying the product number as a barcode. Furthermore, in recent years, an RF-ID tag incorporating an IC chip that can write and read information in a non-contact state is used.

  In an RF-ID tag incorporating an IC chip capable of writing and reading information in a non-contact state, the amount of writable information is much larger than the amount of information that can be displayed on the tag, It is rapidly spreading because it can be easily rewritten. The RF-ID tag includes an electromagnetic induction method using an induced electric power generated by the dielectric magnetic flux of two coils, and a microwave method that performs communication using a microwave band. In the case of a microwave system that performs communication using a band, the communication distance can be extended by the length of a conductive antenna connected to an IC chip.

  In addition, such a tag may be configured to be separable into two in order to manage the sales history of the attached product on the store side. For this reason, it is conceivable that the IC chip and the antenna can be separated into two parts including the part. In that case, among the two separated parts, the IC remains on the part that remains attached to the product after the sale. Since some chips and antennas are included, consumers may be worried that some information may be written after the purchase of the product. . Therefore, it can be considered that the part having the IC chip and the antenna is incorporated only in the two separated parts separated from the product. However, in the case of performing communication using the microwave band as described above, it is preferable that the length of the antenna is longer in order to secure the communication distance. Therefore, the part having the IC chip and the antenna is separated. When it is built in only one side, the size of the tag becomes large in order to secure the desired communication distance, or the length of the antenna can only be shortened according to the tag size, ensuring the desired communication distance You will not be able to do it.

  Here, an RFID tag is conceivable in which a label on which information is printed is detachably attached to the surface of a tag body in which an IC chip and an antenna are incorporated (see, for example, Patent Document 1). When this RFID tag is used, the length of the antenna can be set according to the size of the entire RFID tag, and the label is separated from the tag main body into two parts, and only one of them is an IC. A chip and an antenna can be incorporated.

  Incidentally, coupons such as service tickets and discount coupons are provided to consumers from companies and stores that provide products, etc., and consumers who are provided with coupons use the coupons at stores and the like. You will receive benefits such as discounts. In addition, in companies and stores that provide products and the like, the above-described coupons are provided to consumers to increase sales through benefits such as discounts for consumers. Such coupons are generally provided to consumers by methods such as posting in insert advertisements, magazine advertisements, etc., or distributing them at companies, stores, and the like.

  Here, if the coupon information is displayed on the tag attached to the product as described above, the trouble of distributing the coupon as described above can be saved, and the coupon is provided to the consumer who purchased the product. Can do.

However, when coupon information is displayed on a tag attached to a product, a space for that is required, and the tag becomes large. Therefore, in an RFID tag as described in Patent Document 1, if coupon information is displayed on the label sticking surface of the tag body, the coupon information can be displayed on the tag without increasing the size of the tag. become able to.
JP 2006-11320 A

  In the RFID tag described in Patent Document 1, when coupon information is displayed on the sticking surface of the label of the tag body, the coupon information is released from the tag body at the cash register of the store when the product is sold. When it hits, it becomes visible.

  Here, if the coupon information displayed on the tag body is information that simply indicates a discount, even if the label is peeled off from the tag body at the cash register of the store, the consumer can be visually recognized. However, if the information has lottery elements such as winning / losing, the lottery can be visually recognized by the action of cutting, scoring, or taking out from the bag. For this reason, there is a problem that the consumer feels uncomfortable.

  The present invention has been made in view of the problems of the conventional techniques as described above, and includes an IC chip capable of writing and reading information in a non-contact state and an antenna connected to the IC chip. The RF-ID tag having an inlet sheet is provided with a structure that can be separated into two, and when separated, the inlet sheet can be included in only one, while ensuring a desired communication distance. Provided is an RF-ID tag that can be given coupon information that can be visually recognized by processing different from separation after separation into two without increasing the size of the entire RF-ID tag For the purpose.

In order to achieve the above object, the present invention provides:
First and second sheets that are attached to each other at the peripheral edge and configured so that parts of the attached areas can be separated from each other;
A bag portion formed by surrounding non-adhered portions of the first sheet and the second sheet in the regions adhered to each other;
An IC chip capable of writing and / or reading information in a non-contact state; and an antenna connected to the IC chip, wherein the first sheet and the second sheet are between the first sheet and the second sheet. And having an inlet sheet disposed on the non-sticking portion and attached to a part of the first and second sheets that can be separated.
It said first sheet has a pre-Symbol spread structure visible to the bag portion to the non-adhered portion of the second sheet.

  In the present invention configured as described above, when part of the first and second sheets adhered to each other is cut off, the first sheet and the second sheet are adhered to the part of the first and second sheets. The inlet sheet arranged in the non-sticking portion with the sheet separates from the first and second sheets together with the separated areas of the first and second sheets. Then, by the spread structure provided in the first sheet, the non-adhered portion of the first sheet and the second sheet is visually recognized inside the bag portion formed by being surrounded by the region where they are adhered to each other. If the coupon information is displayed in the region that becomes the bag portion of the second sheet, the coupon information is visually recognized.

  As described above, in the present invention, the first sheet and the second sheet are attached to the first sheet and the second sheet so that the first sheet and the second sheet can be separated from each other. Since the inlet sheet is arranged in the non-sticking portion with the second sheet, the length of the antenna of the inlet sheet depends on the size of the portion where the first and second sheets can be separated. There is no need, and the size can be set according to the first and second sheets. Thereby, a desired communication distance can be ensured. In addition, the inlet sheet is separated from the first and second sheets together with the separated areas of the first and second sheets by separating a part of the first and second sheets adhered to each other. be able to. Moreover, the 1st sheet | seat is formed in the adhesion part with a 2nd sheet, and the non-adhesion part of a 1st sheet | seat and a 2nd sheet | seat is surrounded by the area | region where these were mutually affixed. Therefore, if the coupon information is displayed in the region that becomes the bag portion of the second sheet, the size of the entire RF-ID tag is not increased. After separating the first and second sheets into two, coupon information that can be visually recognized by a process different from the separation can be given.

  Embodiments of the present invention will be described below with reference to the drawings.

  In the present embodiment, as shown in FIG. 1, the adhesive applied to the top sheet 110 with the top sheet 110 as the first sheet and the back sheet 120 as the second sheet sandwiching the inlet sheet 130. It is configured to be adhered to each other at the peripheral edge by the agent 140b.

  The top sheet 110 is configured such that the separation piece 111 and the remaining piece 112 are connected, and the separation piece 111 can be separated by the perforation 113. An adhesive 140b is applied to the periphery of the back surface of the top sheet 110, and the top sheet 110 and the back sheet 120 are attached by the adhesive 140b, and the top sheet 110 and the inlet sheet 130 Is attached. As a result, the front sheet 110 is configured such that a part of the region adhered to the back sheet 120 can be separated by the perforation 113. In addition, a notch 119 is formed at the end of the perforation 113 as a trigger for separating the separation portion 111 and the remaining portion 112. Each of the separation piece 111 and the remaining piece 112 has information display portions 115a and 115b on which the information about the product such as the product number, size, color, and price of the product to which the RF-ID tag is attached are displayed on the same surface. Is provided. In addition, barcode information 117a and 117b in which the product number of the product to which the RF-ID tag is attached is displayed as a barcode is displayed on the same surface of each of the separation piece 111 and the remaining piece 112. This barcode information By reading 117a and 117b, the attached product can be identified. The remaining piece 112 is provided with an attachment hole 114 for attaching the RF-ID tag to a product. Further, in the remaining piece 112, a perforation 116 is formed along a pressure sensitive adhesive 140b in a region where the pressure sensitive adhesive 140b is not applied to the back surface, that is, a non-sticking portion with the back surface sheet 120. A spread structure described later is configured by the eyes 116.

  The back sheet 120 is adhered to the top sheet 110 by the adhesive 140b applied to the top sheet 110, and the separation piece 121 facing the separation piece 111 of the top sheet 110 remains the facing piece 112 of the top sheet 110. The piece 122 is connected so as to be separable by a perforation 123. Thereby, the back surface sheet 120 is configured such that a part of the region adhered to the front surface sheet 110 can be separated by the perforation 123. Further, a cut 129 is formed at the end of the perforation 123 in the same manner as the top sheet 110. Further, the adhesive 140 a is applied to a region facing the region where the inlet sheet 130 is adhered to the top sheet 110 among the regions facing the inlet sheet 130, whereby the inlet sheet 130 is adhered to the separation piece 121. It is worn. Further, coupon information 125 is displayed in a portion facing a region surrounded by the perforation 116 in the non-sticking portion with the top sheet 110. Moreover, the information which shows the brand etc. of the goods to which this RF-ID tag is attached is displayed on the surface on the opposite side to the sticking surface with the surface sheet 110, for example.

  As described above, the top sheet 110 and the back sheet 120 are attached to each other at the periphery by the adhesive 140b applied to the back surface of the top sheet 110, and the region surrounded by the adhesive 140b is not attached. It is the wearing part. Thus, the bag part is formed when the non-adhesion part of the surface sheet 110 and the back surface sheet 120 is surrounded by the area | region where the surface sheet 110 and the back surface sheet 120 were mutually affixed by the adhesive 140b. . The spread structure formed by the perforation 116 in the top sheet 110 is provided in the region that becomes the bag portion, and the inside of the bag portion can be visually recognized by breaking the perforation 116.

  In the inlet sheet 130, a straight line connecting the vertices formed by the equal sides of the isosceles triangles on the base substrate 133 made of PET resin or the like is the base of the isosceles triangle. An antenna is formed so as to be perpendicular to each other and with the vertices having a gap, and is connected to the two conductor portions 132a and 132b in a non-contact state. Thus, an IC chip 131 capable of writing and reading information is mounted. The thus configured inlet sheet 130 is disposed between the top sheet 110 and the back sheet 120 so as to straddle the separation pieces 111 and 121 and the remaining pieces 112 and 122 of the top sheet 110 and the back sheet 120, The adhesives 140a and 140b applied to the back surface of the back sheet 120 and the top sheet 110 are attached only to the separation pieces 111 and 121, respectively. That is, the inlet sheet 130 is affixed to the separation pieces 111 and 121 of the top sheet 110 and the back sheet 120, and is disposed in a non-stick part between the top sheet 110 and the back sheet 120. Thus, since the inlet sheet 130 is disposed so as to straddle the separation pieces 111 and 121 to be separated and the remaining pieces 112 and 122, the length of the antenna of the inlet sheet 130 is set to be equal to the separation pieces 111 and 121 and the remaining pieces. It does not correspond to the size of the pieces 112 and 122, thereby ensuring a desired communication distance.

  When manufacturing the RF-ID tag configured as described above, first, the adhesive 140b is applied to one surface of the continuous surface sheet 110 in a pattern as shown in FIG.
