Description

  The present invention relates to a container lid with an IC tag for detection of opening, and more specifically, a container that cannot be opened unless the antenna of the IC tag is destroyed, and refilling of contents is effectively prevented. Regarding the lid.

Conventionally, in order to prevent unauthorized refilling and mischief and to ensure the safety and quality, various caps have been proposed that have a function of clearly showing the opening history.
In recent years, an information display technique using an IC tag has been used to display product information such as date of manufacture and manufacturer / seller. An IC tag is also referred to as RFID (Radio Frequency Identification), and is an ultra-high frequency tag formed by embedding an IC chip storing predetermined information in a dielectric material such as resin or glass together with a wireless antenna. It is a small communication terminal. Such an IC tag reads product information stored in an IC chip by wireless communication. For example, data of several hundred bytes can be recorded in a memory of the IC chip, and a lot of product information is stored. Since there is an advantage that it can be recorded, it has also been proposed to use such an IC tag for clarifying the opening history.

  For example, in Patent Document 1 below, in a bottle having an IC tag composed of an IC chip, a lead wire, and an antenna, an IC chip is provided on the main body of the bottle or a part belonging to the main body, and the cap is screwed onto the main body. A bottle characterized by an antenna is described.
