Patent

CA 2562665

The invention generally relates to interlocking closure devices including two closure elements arranged to be interlocked over a predetermined length. The closure elements permit the venting of fluids when the closure elements are in their occluded vented position. The closure elements have an occluded closed position which creates a seal and prevents fluids from passing between the interlocking closure elements. The closure fastening device may be utilized with a flexible container and is advantageous in permitting a user to vent excess air from the interior of the flexible container prior to sealing the container.

L'invention porte d'une manière générale sur des fermetures à glissière comportant deux éléments de fermeture conçus pour pouvoir s'interpénétrer sur une longueur prédéterminée. Lesdits éléments permettent à des fluides de s'échapper lorsqu'ils sont en position de fermeture ventilable, mais les empêchent de s'échapper lorsqu'ils sont en position de fermeture où ils forment un joint étanche. Cette fermeture à glissière peut s'utiliser avec des récipient souples dont l'excès d'air peut être évacué avant que leur fermeture ne devienne étanche.
