Description

[Technical field]

[0001] The present disclosure relates to container labels. [Background technology]

[0002] Attaching wireless tags to items in stores such as convenience stores to manage individual items is being considered. When a lunch box with a wireless tag attached is heated in a microwave oven in a store, the wireless tag can burn due to the heat generated by the microwave's electromagnetic waves, creating a danger. For this reason, wireless tags that protect against heat generated by the microwave's electromagnetic waves have been developed.

[0003] For example, Patent Document 1 discloses a wireless tag that includes an antenna and an IC chip, where the antenna has an impedance step, and when the antenna is irradiated with electromagnetic waves from a microwave oven, the current flowing through the IC chip is reduced compared to when the antenna does not have an impedance step, thereby protecting the wireless tag from heat generation caused by the electromagnetic waves from the microwave oven.

[0004] Patent Document 2 discloses a wireless tag detection device that can reduce the possibility of a wireless tag being inserted into a microwave oven. The wireless tag detection device includes an attachment unit, an antenna, a transmission unit, and an alarm unit, and the attachment unit is attached to the microwave oven. The antenna is directed toward an area in front of the input port of the heat generation chamber in which an object to be heated is placed, to which the attachment unit is attached. The transmission unit causes the antenna to transmit electromagnetic waves. The alarm unit issues an alarm on the condition that it receives tag information stored in a wireless tag that has received the electromagnetic waves transmitted by the transmission unit.

[0005] Wireless tags are also called RFID tags, which stands for Radio Frequency Identification. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2019-083412 A [Patent Document 2] JP 2019-100663 A Summary of the Invention [Problem to be solved by the invention]

[0007] Incidentally, wireless tags that protect wireless tags from heat generation caused by electromagnetic waves from microwave ovens, such as the wireless tag described in Patent Document 1, are expensive, and it is therefore preferable and inexpensive to be able to use general-purpose wireless tags as they are.

[0008] Furthermore, the wireless tag detection device described in Patent Document 2 has a problem in that the price of a microwave oven increases by the amount of the wireless tag detection device that is attached to the microwave oven.

[0009] An object of the present disclosure is to provide a container label that can increase the necessity to remove a wireless tag attached to a container from the container before heating the container in a microwave oven. [Means for solving the problem]

[0010] In order to achieve the above object, the container label of the present disclosure comprises: A radio frequency tag circuit element disposed on an opaque seal; a base label having a display portion indicating a heating time in a microwave oven and attached to the container; Equipped with The sticker is attached to the display portion. Effect of the Invention

[Diagram 3] FIG. 3 is a diagram showing the container label with the seal removed. [Figure 4] FIG. 4 is a cross-sectional view of a separator in a modified example of the present embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Fig. 1 is a diagram showing a container label in an embodiment of the present disclosure. Fig. 2 is a cross-sectional view taken along line AA in Fig. 1. The container label 100 shown in Figs. 1 and 2 comprises a wireless tag 200, a base label 500, and a separator 600. The wireless tag 200 comprises a seal 300 and a wireless tag circuit element 400. The left-right direction shown in Fig. 2 is referred to as the "longitudinal direction." Additionally, the top-bottom direction shown in Fig. 2 is referred to as the front-back direction, the top direction is referred to as the "front side" or "seal side," and the bottom direction is referred to as the "back side" or "base label side."

[0014] The seal 300 is an opaque resin seal. The seal 300 is an elongated seal with the longitudinal direction as the long dimension. An adhesive separator 600 is disposed on the back surface of the seal 300. That is, the seal 300 (wireless tag 200) is attached to the base label 500 by the separator 600, and is further attached to the container 1 via the base label 500.

[0015] (RFID circuit element 400) The RFID circuit element 400 is disposed on the sticker 300. The RFID circuit element 400 has a loop antenna section 410, an IC circuit section 420, a capacity hat section 430, and a meander line antenna section 440. The loop antenna section 410 is disposed in the center of the sticker 300. The loop antenna section 410 transmits and receives signals in a non-contact manner to and from an antenna of a reader / writer (not shown). This enables the reader / writer to read tag information from a memory section of the IC circuit section 420 via the loop antenna section 410.

[0016] The IC circuit section 420 has a rectification section (not shown) that rectifies the carrier wave received by the loop antenna section 410, a memory section (not shown) that stores a specified information signal received by the loop antenna section 410, and a control section (not shown) that controls the operation of the RFID circuit element 400.

[0017] The capacity hat portion 430 is disposed on each of both ends of the seal 300. The capacity hat portion 430 accumulates the energy of the carrier wave rectified by the rectification portion so as to use it as a driving power source for the RFID circuit element 400.

[0018] The meander line antenna portion 440 is disposed at each of both ends of the seal 300. The meander line antenna portion 440 has one end and the other end, with the loop antenna portion 410 connected to one end and the capacity hat portion 430 connected to the other end.

[0019] FIG. 3 is a diagram showing the container label with the seal removed. The base label 500 is attached to the container 1 by an adhesive portion (not shown). The front side of the base label 500 displays the "product name," "ingredients," "best before date," and "microwave heating guideline" (see FIG. 3).

[0020] In addition, in FIG. 3, the items "Product name", "Ingredients" and "Expiration date" are displayed, and the contents of "Product name", "Ingredients" and "Expiration date" are omitted. In addition, in FIG. 3, the item "Microwave heating guideline" and the contents of "Microwave heating guideline" such as "1500W 1 minute" and "500W 3 minutes" are displayed. The display unit on which the contents of "Microwave heating guideline" are displayed corresponds to the "display unit" in this disclosure, and is the display unit on which the heating time in the microwave oven is displayed. FIG. 2 shows the display unit 510. The sticker 300 (wireless tag 200) is attached to the display unit 510. FIG. 1 shows the sticker 300 (wireless tag 200) that is attached so as to cover the contents of "Microwave heating guideline" without covering the item "Microwave heating guideline". (Separator 600) The separator 600 is disposed between the seal 300 and the base label 500. An adhesive seal (not shown) is disposed on the back side of the separator 600. Release paper (not shown) is disposed so as to sandwich the adhesive seal between the separator 600 and the base label 500 from the front and back directions. The release paper is removed from the adhesive seal before the seal 300 (wireless tag 200) is affixed to the base label 500 by the adhesive seal. In addition, the adhesive seal has an adhesive strength sufficient to not damage the base label 500 when the seal 300 (wireless tag 200) is removed from the base label 500.

[0021] The separator 600 is a plate-like member made of resin having a predetermined thickness. The thickness of the separator 600 and the type of resin material are set from the viewpoint of the distance (communication distance) between the seal 300 (wireless tag 200) attached to the container 1 and the reader / writer (not shown) and according to the material (metal or resin) of the container 1 to which the seal 300 (wireless tag 200) is attached, and can be obtained by experiment or simulation. In other words, it is possible to adjust the communication distance by adjusting the thickness of the separator 600 or changing the type of resin material.

[0022] The container label 100 in the above embodiment comprises a base label 500 that is affixed to the container 1 and has a radio tag circuit element 400 arranged on an opaque sticker 300 and a display section 510 that displays the heating time in a microwave oven, and the sticker 300 is affixed to the display section 510.

[0023] With the above configuration, before heating a lunch box with wireless tag 200 attached in a microwave oven, it is necessary to remove sticker 300 (wireless tag 200) attached to display unit 510 from container 1 in order to check the heating time displayed on display unit 510. This increases the necessity for removing sticker 300 (wireless tag 200) from container 1 before heating in a microwave oven.

[0024] (Modification) FIG. 4 is a cross-sectional view of a separator in a modified example of this embodiment. The separator 600 in the above embodiment is a plate-shaped member made of resin having a predetermined thickness. The present disclosure is not limited to this, and the separator 600 may have a seal side portion 610 facing the front side (seal side), a base label side portion 620 facing the back side (base label side), and a hollow portion 630 disposed between the seal side portion 610 and the base label side portion 620, as shown in FIG. 4. This makes it possible to adjust the communication distance between the seal 300 (wireless tag 200) and the reader / writer (not shown) by changing the thicknesses of the seal side portion 610 and the base label side portion 620 and the dimensions of the hollow portion 630 in the front-back direction.

[0025] In addition, the above-mentioned embodiments are merely examples of the embodiment of the present disclosure, and the technical scope of the present disclosure should not be interpreted as being limited by them. In other words, the present disclosure can be embodied in various forms without departing from the gist or main features thereof. [Industrial Applicability]
