Title (EN) FLEXIBLE STORAGE BAG
(FR) SAC SOUPLE DE STOCKAGE
Abstract:
(EN) The flexible storage bag includes overlaying first and second sidewalls defining an internal volume that can be accessed form an open top edge. To evacuate air from the internal volume after the open top edge has been closed, the bag includes a one-way valve element attached to the first sidewall and communicating with the internal volume. To prevent the one-way valve element from becoming clogged by the opposing second sidewall, the bag also includes a clearance member that maintains at least a partial clearance between the first and second sidewalls proximate the valve element. The clearance member can take many forms such as a textured portion on the second sidewall that includes evacuation passages which provide air in the internal volume access to the valve element, a permeable element covering the valve element, and a rigid or compressible structure that spaces the second sidewall from the valve element.
(FR) L'invention porte sur un sac souple de stockage comprenant une première et une deuxième paroi se recouvrant et délimitant un volume intérieur auquel on accède par l'un des bords supérieurs ouverts. Pour évacuer l'air du volume intérieur après la fermeture du bord ouvert, le sac est muni d'une soupape unidirectionnelle fixée à l'une des parois et communiquant avec le volume intérieur. Pour éviter que l'une des parois ne se colle à l'autre, le sac comporte également un espaceur maintenant une distance entre les parois, au moins en partie autour de la soupape. Ledit espaceur peut avoir différentes formes, et par exemple consister en une partie texturée de la deuxième paroi comprenant des passages d'évacuation permettant à l'air intérieur d'accéder à la soupape, ou en un élément perméable recouvrant la soupape, ou en une structure rigide ou compressible qui éloigne la soupape de la deuxième paroi.
