[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. 1 is a functional block diagram showing functions of a detection system according to an embodiment of the present disclosure. In this embodiment, the container is described as a bag container. The detection system 100 shown in FIG. 1 includes an RFID tag 200 and an opening detection device 400.

[0012] (RFID tag 200) The RFID tag 200 is a sticker-type RFID tag that can be attached to the bag container 1. The RFID tag 200 comprises a label body (not shown) and an RFID circuit element 300. The label body is a long label with the longitudinal direction as the long side. The label body has a central portion located at the center in the longitudinal direction and both end portions located on either side of the central portion in the longitudinal direction. An adhesive portion (e.g., an adhesive sticker) is arranged on the back side of the label body. In other words, the label body (RFID tag 200) is attached to the bag container 1 by the adhesive portion.

[0013] (RFID circuit element 300) The RFID circuit element 300 has a loop antenna section 310, an IC circuit section 320, a capacity hat section 330, and a meander line antenna section 340 (see FIGS. 2A and 2B).

[0014] (Opening detection device 400) The opening detection device 400 has an antenna 410, a reader 420 (corresponding to the "reading unit" of the present disclosure), a detection unit 430, a storage unit 440, and a notification unit 450. The opening detection device 400 also has a control unit (not shown) that comprehensively controls the entire device.

[0015] The loop antenna unit 310 is located in the center of the label body. The loop antenna unit 310 transmits and receives signals to and from the antenna 410 in a non-contact manner. This allows the reader 420 to read predetermined information from the memory unit of the IC circuit unit 320 via the loop antenna unit 310.

[0016] The IC circuit section 320 is disposed in the center of the label body and has a rectifier section (not shown) that rectifies the carrier wave received by the loop antenna section 310, a memory section (not shown) that stores a predetermined information signal received by the loop antenna section 310, and a control section (not shown) that controls the operation of the RFID circuit element 300.

[0017] The capacity hat portions 330 are arranged at both ends of the label body. The capacity hat portions 330 store the energy of the carrier wave rectified by the rectifier portion so as to be used as a driving power source for the RFID circuit element 300.

[0018] The meander line antenna portion 340 is disposed at each end of the label body. The meander line antenna portion 340 has one end connected to the loop antenna portion 310 and the other end connected to the capacity hat portion 330.

[0019] FIG. 2A is a diagram showing an example of an RFID tag attached to a bag container according to an embodiment of the present disclosure. Bag container 1 shown in FIG. 2A is marked with perforation line 2 for opening. RFID tag 200 shown in FIG. 2A is positioned on perforation line 2. Specifically, RFID tag 200 is attached to bag container 1 so that loop antenna unit 310, located in the center of the label body, is positioned on perforation line 2. Therefore, when bag container 1 is cut along perforation line 2 with scissors 3 to open it, loop antenna unit 310 is simultaneously cut. This causes RFID tag 200 to malfunction, making it impossible for reader 420 to read the identification information of the RFID tag and for detection unit 430 to detect the identification information of the RFID tag.

[0020] FIG. 2B is a diagram illustrating another example of an RFID tag affixed to a bag container according to an embodiment of the present disclosure. The bag container 1 illustrated in FIG. 2B has a tear line 2 for opening. The RFID tag 200 illustrated in FIG. 2B is affixed to the bag container 1 so that the loop antenna portion 310, located in the center of the label body, and the capacity hat portion 330 and meander line antenna portion 340, located at both ends of the label body, are positioned on the tear line 2. Therefore, when the bag container 1 is cut along the tear line 2 with scissors 3 to open the bag container 1, the loop antenna portion 310, the capacity hat portion 330, and the meander line antenna portion 340 are simultaneously cut. This causes the RFID tag 200 to malfunction, making it impossible for the reader 420 to read the RFID tag's identification information and for the detector 430 to detect the RFID tag's identification information.

[0021] The detection unit 430 detects the identification information (tag ID shown in FIG. 1) of the RFID tag read by the reader. If the detection unit 430 cannot detect the tag ID, it detects that the bag container 1 has been opened. If the opening of the bag container 1 is detected, the tag ID, opening flag, and opening date are stored in the memory unit 440.

[0022] Notification unit 450 notifies the user of the tag ID and the opening date read from storage unit 440. Specifically, notification unit 450 is a display unit that displays the tag ID and the opening date as character data. Note that notification unit 450 may notify the user of the opening date on the opening date, or may notify the user of the opening date after the opening date, for example, by a user's input operation.

[0023] The detection system 100 in the above embodiment comprises an RFID tag 200 having a loop antenna unit 310, the loop antenna unit 310 being positioned on an opening cut line 2 marked on the bag container 1, and an opening detection device 400. The opening detection device 400 comprises an antenna 410 that transmits and receives signals to and from the loop antenna unit 310 via wireless communication, a reader 420 that can read the identification information (tag ID) of the RFID tag 200 via the antenna 410, a detection unit 430 that detects that the bag container 1 has been opened if the identification information cannot be read, a memory unit 440 that stores the opening date on which the bag container 1 was opened if it is detected that the bag container 1 has been opened, and a notification unit 450 that notifies the opening date.

[0024] With the above configuration, when the bag container 1 is opened, the opening date is automatically notified, eliminating the need for workers to make a note of the opening date, thereby improving workability after the bag container is opened.

[0025] Although the container in the above embodiment has been described as a bag container 1, the present disclosure is not limited to the bag container 1. For example, it may be a box container.

[0026] (Variation 1) Next, a first modification of the present embodiment will be described with reference to Fig. 3. Fig. 3 is a diagram showing the relationship between the detection system and the terminal device in the first modification of the present embodiment. In the description of the first modification, differences from the above embodiment will be mainly described, and the same components will be assigned the same reference numerals and descriptions thereof will be omitted.

[0027] The detection system 100 in the first modification includes a terminal device 5. The terminal device 5 is, for example, a smartphone or a tablet terminal. The terminal device 5 has a communication unit (not shown) that performs data communication with the opening detection device 400. As a result, the terminal device 5 receives the item name and the opening date, stores them in a memory (not shown), and displays the item name and opening date read from the memory on a display. The item name and opening date displayed on the display are shown in FIG. 3.

[0028] In the detection system 100 of the first modification, the product name and the opening date are stored in memory and are also displayed on a display. This eliminates the need for workers to make a note of the opening date, thereby improving workability after the bag container is opened.

[0029] (Variation 2) Next, a second modification of the present embodiment will be described with reference to Fig. 4. Fig. 4 is a functional block diagram showing the functions of a detection system in a second modification of the present embodiment. In the description of the second modification, differences from the above-described embodiment will be mainly described, and the same components will be assigned the same reference numerals and descriptions thereof will be omitted.

[0030] The detection system 100 in the second modification includes a server 500. The opening detection device 400 also includes a communication unit 460 that performs data communication with the server 500.

[0031] The communication unit 460 transmits the tag ID and the opening date to the server 500. The communication unit 460 receives the item information (described later) and other additional information (described later) from the server 500. This enables the notification unit 450 to notify the item information and other additional information in addition to the opening date.

[0032] Server 500 has a storage unit 510, a collation unit 520, and a notification unit 530. Storage unit 510 stores a list in which tag IDs are associated with item information. The item information includes the product name, an image of the product's appearance, the expiration date after opening, and other additional information.

[0033] Based on the tag ID transmitted from the communication unit 460, the matching unit 520 refers to the list and matches the item information associated with the tag ID.

[0034] Notification unit 530 notifies the opening date, product information, and other additional information. Specifically, notification unit 530 is a display unit that displays the opening date, product information (including the expiration date after opening), and other additional information as character data.

[0035] In the detection system 100 of the second modification, the opening date, product information (including the expiration date after opening), and other additional information are displayed on the notification unit 530 of the server 500. This eliminates the need to make a note of the opening date, and also makes it easier to manage expiration dates, etc.

[0036] Furthermore, the above-described embodiments are merely examples of specific embodiments for carrying out the present disclosure, and the technical scope of the present disclosure should not be interpreted as being limited by these embodiments. In other words, the present disclosure can be carried out in various forms without departing from its gist or main features. [Industrial Applicability]
