wherein the actuating element is configured such that the handle section can no longer be permanently repositioned back into the starting position after it is initially repositioned from the starting position;
and/or
wherein the actuating element is configured such that it plastically deforms, in particular permanently and/or permanently visually recognizable, when the handle section is initially repositioned from the starting position.
14 . The can lid according to claim 1 ,
wherein the actuating element has a locking section by which the actuating element is locked in the closed position on the lid panel prior to an initial repositioning from the closed position to the open position.
