Guala Closures has patented a closure element for containers with a unique transponder design. The inner and outer cap members house a transponder with a chip, antenna, and control loop. A relative rotation of the caps applies force to break the control loop, ensuring tamper-evidence.

A newly granted patent (Publication Number: US11907792B2) discloses a closure element designed for sealing containers. The closure element consists of an inner cap member and an outer cap member, with a transponder containing a chip, an antenna, and a control loop housed between them. The unique feature of this closure element is the attachment of the chip to one of the top walls of the inner and outer cap members, while a portion of the control loop is attached to the other top wall. This configuration allows for a torsion or shear force to act on the control loop when the outer cap member is rotated relative to the inner cap member, ultimately breaking the loop.

Furthermore, the closure element includes a substrate on which the transponder is mounted, with the substrate having two portions folded onto each other. The substrate design allows for the attachment of the first portion to one top wall and the second portion to the other top wall of the cap members. Additionally, the closure element features anti-rotation means, such as ribs and centring features, to ensure the proper alignment and functioning of the closure element. The patent also highlights the use of a radio frequency identification tag as the transponder, specifically mentioning a near field communication tag as a preferred option. Overall, the patented closure element offers a novel and efficient way to seal containers while incorporating advanced technology for tracking and identification purposes.
