Abstract
A closure element for closing a container comprises an inner cap member coupled with a mouth of the container, an outer cap member movably coupled to the inner cap member, and a transponder having a chip and an antenna housed between the inner and outer cap members. The closure element further comprises two first capacitor plates connected with the chip, which are attached to one of a top wall of the inner cap member and a top wall of the outer cap member, and a second capacitor plate attached to the other of the top wall of the inner cap member and the top wall of the outer cap member, such that a relative movement of the outer cap member and the inner cap member switches the closure element between a first configuration and a second configuration having a different capacitance between the first and second capacitor plates.
