Description

TECHNICAL FIELD The present invention relates to an RFID container and a manufacturing method for an RFID container. BACKGROUND ART A manufacturing method for an RFID container as described in the preamble of claim 1 and an RFID container as described in the preamble of claim 12 are already known from JP 2020 030703 A. JP 2021 140439 A discloses a similar manufacturing method for an RFID container as described in the preamble of claim 1 and a similar RFID container as described in the preamble of claim 12. WO 2018/163111 A1 refers to container labels. In the related art, a label that can be attached to a cylindrical body such as a blood-collecting tube or a test tube has been proposed (see JP H11-73109A). The label described in JP H11-73109A has perforations or through holes formed in label end portions in order to prevent the label end portions from floating without following a curved surface of the test tube. In recent years, in fields of manufacture, management, distribution, and the like of products, movements have been promoted to apply a radio frequency identification (RFID) technique for transmitting and receiving information by non-contact communication to and from an IC chip in which information related to the products and identification information are written. In order to mount an RFID-corresponding antenna and an IC chip on a container such as a blood-collecting tube or a test tube, for example, a method has been adopted in which an RFID inlay in which an antenna and an IC chip are provided on an inlay base material is manufactured in advance, and the RFID inlay is attached to the container as a label or attached to the container as a tag. SUMMARY OF INVENTION In a case of the container such as a blood-collecting tube or a test tube, the container may be used in a severe environment such as an extremely low temperature or a high temperature and high humidity. Therefore, in the method of mounting the RFID antenna and the IC chip on the container using the RFID inlay, environmental followability of the inlay base material exceeds an allowable range, and accordingly, the RFID antenna and the IC chip may remove off. Therefore, an object of the present invention is to provide a manufacturing method for an RFID container and an RFID container capable of preventing an RFID antenna and an IC chip from removing off. The above and other objects of the invention are solved by the manufacturing method for an RFID container according to claim 1 and the RFID container according to claim 12. Preferred embodiments are claimed in the dependent claims. According to an embodiment of the present invention, there is provided a manufacturing method for an RFID container having an antenna and an IC chip, including: a process of temporarily attaching the antenna to a base material by a first adhesive; a process of fixing the IC chip to the antenna; a process of attaching a front surface of the container and a surface of the base material on which the antenna is formed by a second adhesive; and a process of removing, while leaving a partial region of the base material covering the IC chip on the front surface of the container, a region of the base material other than the partial region covering the IC chip from the container. According to the above-mentioned embodiment, the antenna and the IC chip are directly attached to the front surface of the container. According to the embodiment of the present invention, since no RFID inlay is present, floating of an RFID inlay from a front surface of an adherend does not occur. Therefore, the RFID antenna and the IC chip can be prevented from removing off.
