The eco-friendly reusable cup features wireless identification on its bottom edge.

Abstract

An environmentally friendly reusable cup wireless identification bottom frame structure is disclosed. The reusable cup includes: a cup body, which is an insulated cup body, with a frame chamber formed by extending the bottom frame of the cup body from the bottom of the cup body outside the liquid-containing cup chamber; a cover piece that is connected to the bottom frame of the cup to close the frame chamber, and a frame ring forming an electromagnetic wave sensing space in the frame chamber; a wireless radio frequency identification tag, which is placed around the electromagnetic wave sensing space, with a pair of extended antennas extending from both sides of the aperture-shaped main antenna of the tag and a groove opened as a circuit pad electrically connected to an ultra-high frequency wireless radio frequency identification chip; the overall structure enables the reusable cup to use the wireless radio frequency identification tag, and in addition to not having problems with chemical resistance, peeling or external force damage, it also improves the long-distance (far-field) reading effect when identifying in batches.
