A closure (11) for a container (10) has a tamper indicating band (22) with a band retainer (29) in the form of an apertured flap or hoop which is hinged to the lower edge (30) of the band. A series of windows (36) open through the retainer, extending toward but not to its distal edge (32). As the retainer is turned inside out from its as-molded position to its use position, its distal and/or outer edges deform to relieve compression and permet the retainer to be inverted by direct downward pushing force. As a result of the deformation, the retainer in its use position may, depending on the number and relative size of windows, have an advantageous polygonal peripheral shape rather than a circular shape.
Cette invention concerne une fermeture (11) de contenant (10) comportant une bande témoin d'inviolabilité (22) munie d'une bague de retenue (29) ajourée qui est articulée à sa rive inférieure (30). La bague de retenue comporte une série d'ouvertures (36) qui se prolongent vers sa rive libre (32) sans l'atteindre. Lorsque cette bague est relevée vers sa position opérante, sa rive libre se déforme pour réduire les forces de compression, ce qui permet à une poussée directe vers le bas rabattre la bague. Par suite de la déformation, la bague en position opérante peut présenter une section polygonale plutôt que circulaire, fonction du nombre et de la taille relative des ouvertures.
