Abstract
A bottle closure, designed to make apparent any previous opening, consists of a cap, a collar extending coaxially in elongation of the cap, a line of weakness between the cap and the collar. A plurality of tabs project inwardly from the collar and are arranged close to the line of weakness and designed to engage in a circumferential recess which is made on the inside of the cap in proximity to the line of weakness, serving as a bridge across the line of weakness. When the cap is removed from the collar the tabs snap out of the recess and cannot re-enter it, so that a fissure is visible between the cap and the collar, showing that the cap has been removed.
