Title
(EN) A SELF-CLOSING CLOSURE
(FR) DISPOSITIF D'OBTURATION A FERMETURE AUTOMATIQUE
Abstract
(EN)
A self-closing closure assembly (13) for a container (11) of particulate material, e.g. talcum powder, and comprising a closure body (14) having a part spherical external surface (30) in which at least one aperture (33) is provided for dispensing powder from the container, a cover (15) mounted on the closure body (14) and having a part spherical inner surface (42) that is slidable over the external surface (30) between an aperture-closed position, and an aperture-open position, and biasing means (16) formed integrally with one of the cover (15) and body (14) to urge the cover towards the closed position. The cover (15) may be provided with a tamper-evident stop (52).
(FR)
L'invention concerne un dispositif d'obturation à fermeture automatique (13) pour un récipient (11) contenant un matériau particulaire, par exemple, de la poudre de talc. Ce dispositif comprend un corps d'obturation (14) présentant une surface externe partiellement sphérique (30) dans laquelle au moins une ouverture (33) est prévue pour distribuer de la poudre à partir du récipient. Un couvercle (15) est fixé sur le corps d'obturation (14) et présente une surface intérieure partiellement sphérique (42) qui peut glisser sur la surface externe (30) entre une position d'ouverture fermée et une position d'ouverture ouverte, et un moyen de décalage (16) solidaire soit du couvercle (15) soit du corps (14) pour pousser le couvercle de force vers la position fermée. Le couvercle (15) peut être pourvu d'un élément d'arrêt protégé contre toute utilisation frauduleuse (52).
