Abstract

Pour atteindre les objectifs susmentionnés, la présente invention concerne un ensemble à couvercle (11) et col (12) filetés permettant d'indiquer une effraction sur un récipient (13), comprenant un col (12) de récipient (13) présentant une forme cylindrique et une ouverture sur son extrémité supérieure, le col (12) possédant des filets sur sa surface extérieure et un collier d'étanchéité (14), le collier d'étanchéité (14) comportant une pluralité de dents (15), et un couvercle (11) présentant une forme cylindrique et possédant des filets sur sa surface intérieure, le couvercle (11) comportant un anneau d'indication d'effraction (16) accouplé sur la bague inférieure (17) du couvercle (11), l'anneau d'indication d'effraction (16) possédant un diamètre supérieur au diamètre du couvercle (11). L'anneau d'indication d'effraction (16) comprend une pluralité de pattes inversables (18) faisant saillie longitudinalement à partir de la boucle inférieure (17) de l'anneau d'indication d'effraction (16), les pattes réversibles (18) étant accouplées sur la boucle inférieure (17) de l'anneau d'indication d'effraction (16) au moyen d'une membrane articulable. Au moins l'une des pattes inversables (18) comprend un mécanisme de blocage articulable (22) par rapport à la patte. Ainsi, lorsque le couvercle (11) subit un mouvement de rotation dans le sens de fermeture du couvercle (11) sur la bouteille, le mécanisme de blocage pivote vers une position de passage permettant son passage sur les dents (15) du col (12) de la bouteille, et lorsque le couvercle (11) subit un mouvement de rotation dans le sens de fermeture du couvercle (11) sur la bouteille, le mécanisme de blocage pivote vers une position de blocage ne permettant pas son passage sur les dents (15) du col (12) de la bouteille.
