A closure (2) having a tamper-evident band (4) secured to a container neck by a retaining band. The tamper-evident band (4) is attached to the retaining band (10) by a hinge (12) so that the retaining band (10) rotates upward about the hinge when the closure is applied to the neck of a container, causing the inner wall (26) of the retaining band and the inner wall (15) of the tamper-evident band to form a cavity therebetween. A number of rectangular openings (28) are spaced around the circumference of the retaining band. The upper edge of each opening extends beyond the hinge and into the tamper-evident band. A recess (24) in the inner wall of the tamper-evident band is located above each opening so that the lower edge of the recess intersects with the rear wall of the opening. The openings and recesses cooperate to ensure that any liquid that spills or splashes from the container neck into the cavity during capping will drain out.

La présente invention concerne un dispositif de fermeture (2) pourvu d'une bande inviolable (4) fixée sur le col d'un récipient par une bande de retenue. La bande inviolable (4) est fixée à la bande de retenue (10) par une charnière (12) afin que la bande de retenue (10) tourne vers le haut autour de la charnière lorsque le dispositif de fermeture est appliqué sur le cou du récipient, amenant ainsi la paroi interne (26) de la bande de retenue et la paroi interne (15) de la bande inviolable à former une cavité entre elles. En outre, un certain nombre d'ouvertures rectangulaires (28) sont espacées autour de la bande de retenue. Le bord supérieur de chaque ouverture s'étend au-delà de la charnière jusqu'à l'intérieur de la bande inviolable. Un évidement (24) dans la paroi interne de la bande inviolable est situé au-dessus de chaque ouverture, de façon à ce que le bord inférieur de l'évidement croise la paroi arrière de l'ouverture. Ces ouvertures et évidements coopèrent pour assurer que tout liquide se déversant ou se projetant du col du récipient dans la cavité lors de l'encapsulation sera évacué.
