Abstract
A closure element for closing a container, comprises an inner cap member to be coupled with a mouth of the container; an outer cap member rotatably coupled to the inner cap member, and a transponder housed between the inner cap member and the outer cap member. the transponder comprises a chip, an antenna, and a control loop. The chip is attached to one of a top wall of the inner cap member and a top wall of the outer cap member and at least a portion of the control loop is attached to the other of a top wall of the inner cap member and a top wall of the outer cap member, in such a way that a relative rotation of outer cap member and the inner cap member determines a torsion or shear force to act on the control loop to break it.
