On the security strip of a closure unit there are arranged two pairs of retaining cams lying diagonally opposite. The retaining cams prodtruding into the free cross section of the security strip are axially displaced. On closing the bottle firstly the first retaining cam pair is spread and slides over the retaining rib. Afterwards the second retaining cams displaced by 90° are spread and likewise slide below the retaining rib. On opening, firstly the second retaining cams are held back on the retaining rib and the connecting webs to the screw closure are torn. Afterwards also the remaining webs are torn as soon as the first retaining cams are prevented from an axial displacement by the retaining rib.
Sur la bande de sécurité (3) d'une unité de fermeture (1) se trouvent deux paires d'ergots de retenue (12a, 12b; 13a, 13b) disposés diagonalement en regard. Ces ergots de retenue (12a, 12b; 13a, 13b) faisant saillie dans la largeur intérieure de la bande de sécurité (3) sont axialement décalés. Lors de la fermeture de la bouteille (17), la paire d'ergots de retenue (12a, 12b) est tout d'abord écartée puis glisse au-dessus de la nervure de retenue (15). Ensuite, les ergots de retenue (13a, 13b) décalés de 90 DEG sont écartés et glissent également au-dessous de la nervure de retenue (15). Lors de l'ouverture, les ergots de retenue (13a, 13b) sont d'abord retenus sur la nervure de retenue (15), et les nervures de liaison (9) avec la fermeture vissée (2) se brisent. Ensuite, les nervures restantes (9) se brisent également dès que les ergots de retenue (12a, 12b) décalés axialement sont bloqués par la nervure de retenue (15).
