Hidden electronic tag structure on the bottom edge of the reusable cup

Abstract

A hidden electronic tag structure for the bottom edge of a reusable cup is disclosed. The reusable cup includes: a cup body, which is an insulated cup body; a frame chamber formed by extending the bottom edge of the cup body from the bottom of the cup outside the liquid-containing cup chamber, and a tag-receiving groove axially extending from the end; a cover of a frame member, which is attached to the end of the bottom edge of the cup to close the tag-receiving groove; and a radio frequency identification (RFID) tag placed in the tag-receiving groove, with a pair of extended antennas extending from both sides of the aperture-shaped main antenna of the RFID tag and a groove formed as a circuit pad electrically connected to an ultra-high frequency RFID chip. The overall structure enables the reusable cup to use the RFID tag, and in addition to eliminating the problems of chemical resistance, peeling, or external force damage, it also improves the long-distance (far-field) reading effect during batch identification.
