Abstract

Valve bi-directionnelle pour des récipients thermosoudables caractérisée en ce qu'elle comprend un corps présentant entre ses deux extrémités une bride de fixation avec le récipient, un couvercle perforé solidaire de chaque extrémité dudit corps et définissant avec celui-ci une chambre où est disposé un organe flexible coopérant avec un passage débouchant sur le côte de la bride opposée de celui-ci où se trouve ledit organe, lesdits couvercles pouvant être déplacés d'une première position à une deuxième position correspondant à une fermeture complète du passage relatif. L'invention peut être utilisée sur des récipients notamment destinés à des produits alimentaires.
