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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) Closure element (10) according to claim 1, further comprising a substrate (50) on which the transponder (40) is housed; the substrate (50) comprising a first portion (51) housing the chip (41) and the antenna (42) and a second portion (52) housing said portion (43a) of the control loop (43); the first portion (51) being folded onto the second portion (52). ### Claim 3 (depends on 2) Closure element (10) according to claim 2, wherein the first portion (51) of the substrate (50) 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 the second portion (52) of the substrate (50) 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). ### Claim 4 (depends on 3) Closure element (10) according to claim 3, wherein the first portion (51) of the substrate (50) is attached to the top wall (21) of the outer cap member (20) and the second portion (52) of the substrate (50) is attached to the top wall (31) of the inner cap member (30). ### Claim 5 (depends on 2) Closure element (10) according to claim 2, wherein the first portion (51) of the substrate (50) and the second portion (52) are joined by means of a hinge portion (53);
