Title:
PREFORM LAYERED BODY AND LAYERED CONTAINER
Document Type and Number:
WIPO Patent Application WO/2022/163118
Kind Code:
A1
Abstract:
[Problem] To provide a preform layered body suitable for producing a layered container wherein a tag has been inserted in an appropriate state between layers, and, a layered container produced by biaxial stretch-blow forming of the layered body. [Solution] In this preform layered body 100, an RFID tag 30 has been inserted between an inner layer-use mouth part 114 and an outer layer-use mouth part 124 that are to remain unaltered, with no biaxial stretch-blow forming performed thereon, as a container mouth part 4 for a layered container 1. Since the container mouth part 4 does not become exposed to the high temperature and high pressure for stretch-blow forming purposes, abuses to the RFID tag 30, such as damage, breakage, and deformation, which arise from the heating, pressurization, and stretching during the stretch-blow forming, can be avoided reliably. In addition, labor-saving and counterfeit prevention effect can be anticipated by causing the RFID tag 30 to hold product information.
