Closure element having a transponder between an inner cap member and an outer cap member

Closure element (10) for closing a container (100), comprising:

• an inner cap member (30) to be coupled with a mouth of the container (100);
• wherein the inner cap member (30) has a top wall (31) and a side wall (32) extending from an edge of the top wall (31);
• an outer cap member (20) rotatably coupled to the inner cap member (30);
• wherein the outer cap member (20) has a top wall (21) and a side wall (22) extending from an edge of the top wall (21);
• a transponder (40) housed between the inner cap member (30) and the outer cap member (20);
• the transponder (40) comprising a chip (41), an antenna (42) and a control loop (43);
• characterised in that
• the chip (41) is attached to one of the top wall (31) of the inner cap member (30) and the top wall (21) of the outer cap member (20) and at least a portion (43a) of the control loop (43) is attached to the other of the top wall (31) of the inner cap member (30) and the top wall (21) of the outer cap member (20), in such a way that a relative rotation of the outer cap member (20) and the inner cap member (30) determines a torsion or shear force to act on the control loop (43) to break it.
