A valve assembly for use with a self-sealing collapsible storage bag, the valve assembly having a first portion comprising a housing that has a sealing surface and contains a valve mechanism. A second portion has a sealing surface that is configured to mate with the sealing surface of the first portion. A snap mechanism is configured to allow the first and second portions to be snapped together with their respective sealing surfaces facing each other to form a substantially airtight seal. In operation, the first and second portions are positioned on opposing sides of a panel of a plastic storage bag, and snapped together so as to sandwich the panel between the first and second portions of the valve assembly. The plastic bag is pierced in the area of the valve assembly either during installation of the valve assembly, or later by insertion of a nozzle. Gas or fluid such as air may be selectively removed from or added to the interior of the storage bag through the valve mechanism.

L'invention décrit un ensemble valve qui s'utilise avec un sachet de conservation pliable à fermeture hermétique, cet ensemble valve comprenant une première partie composée d'un logement pourvu d'une surface de fermeture hermétique comportant un système de valve. Une seconde partie possède une surface de fermeture hermétique qui est configurée pour s'accoupler avec la surface de fermeture hermétique de la première partie. Un système à pression est conçu pour permettre aux première et seconde parties de s'unir par pression en maintenant leur surface de fermeture hermétique respective face à face de manière à obtenir une fermeture sensiblement hermétique. Lors de l'utilisation, les première et seconde parties de l'ensemble valve se placent sur les cotés opposés d'un panneau de sachet de conservation en plastique, et s'unissent par pression pour retenir entre elles le panneau. Le sachet en plastique est percé dans la zone de l'ensemble valve soit au cours de l'installation de l'ensemble valve, soit ultérieurement, par introduction d'une buse. Un gaz ou un fluide tel que l'air peut être sélectivement éliminé ou introduit à l'intérieur du sachet de conservation à travers le système de valve.
