CA 2625576

A reclosable storage bag and zipper tape for use in conjunction with same is disclosed. The reclosable bag includes first and second panels which are sealed about bottom, left, and right edges leaving an open top. The closure system further includes first and second closure assemblies or zippers which can be individually or simultaneously closed to seal the contents within the bag. Even after the first and second zippers are engaged thereby closing the bag, excess air within the bag can be removed simply be manually compressing the bag and thereby forcing the air through the vent apertures provided between the zippers. A valve internal to the closure system may be provided proximate the vent apertures and open upon sufficient application of pressure thereby allowing for air to be evacuated from the bag.

Sac d'emballage refermable et fermeture à glissière à utiliser conjointement avec celui-ci. Le sac refermable est composé de deux panneaux scellés à ses bords inférieur, gauche et droit. Le bord supérieur est ouvert. Le système de fermeture comprend deux fermetures, ou glissières, qui peuvent être ouvertes une à la fois ou en même temps, afin de sceller le contenu du sac. Même si les deux glissières sont en prise et ferment le sac, l'excédent d'air peut être enlevé en comprimant le sac à la main, ce qui force l'air à travers les ouvertures d'évacuation qui se trouvent entre les glissières. Un clapet se trouve du côté intérieur des fermetures, près des ouvertures d'évacuation. Lorsque suffisamment de pression est appliquée sur le sac, il permet à l'air de s'échapper du sac.
