Patent

CA 2631168

The invention relates to a closing system for containers for storing or administering liquid, pasty or powdery materials, consisting of a cap (81, 82) provided with a through-hole (85) and a closing element (60), the cap holding the closing element on the container (10, 50) in a non-positive or positive manner, in the region of the opening (12) to be closed, by means of a rear grip (37) on the container. To this end, the front surface (21) surrounding the container opening and on which the closing element is arranged comprises a recess (24, 25). The closing element is a virus-tight, bacteria-tight and spore-tight film which lies on the front surface and at least partially over the recess. An elastomer or adhesive ring (71, 72) filling the recess is arranged between the closing element and the recess for the positioning of the cap. The invention provides a closing system for containers which enables the container to be closed in a virus-tight, bacteria-tight, spore-tight and lastingly secure manner.

L'invention concerne un système de bouchage pour récipients pour conserver ou administrer des substances liquides, pâteuses ou pulvérulentes, qui comprend un capuchon (81, 82) muni d'un trou de passage (85) et un élément de bouchage (60). Le capuchon maintient, par assemblage à force ou par complémentarité de forme, l'élément de bouchage sur le récipient (10, 50), dans la zone de l'ouverture (12) à boucher, au moyen d'un élément de préhension arrière (37) prévu sur le récipient. A cet effet, la surface frontale (21) entourant l'ouverture du récipient sur laquelle repose l'élément de bouchage présente un évidement (24, 25). L'élément de bouchage est un film étanche aux virus, aux bactéries et aux spores, qui repose sur la surface frontale et, au moins par endroits, au-dessus de l'évidement. Lors de la mise en place du capuchon, une bague élastomère ou adhésive (71, 72) qui remplit l'évidement est disposée entre l'élément de bouchage et l'évidement. L'invention permet de mettre au point un système de bouchage pour récipients, qui assure un bouchage étanche aux virus, aux bactéries et aux spores et durablement fiable du récipient.
