Abstract

L'invention concerne une valve comprenant une couche de base possédant une ouverture traversante et une couche supérieure souple qui recouvre la couche de base et qui est jointe à celle-ci de façon à couvrir l'ouverture. La couche de base et la couche supérieure sont également jointes en vue de l'obtention d'un canal extensible et rétractable entre l'ouverture et un point de sortie sur la valve. A l'état normal, pour fermer la valve de manière étanche, le canal est rétracté et la couche de base et la couche supérieure sont adjacentes l'une par rapport à l'autre. Pour faciliter la fermeture étanche de la valve, un matériau d'étanchéité semi-rigide est utilisé dans le canal en contact étanche avec la couche de base et la couche supérieure. En cours d'utilisation, l'air entrant dans l'ouverture déplace la couche supérieure et provoque l'extension du canal, ce qui permet à l'air de passer sur le matériau d'étanchéité semi-rigide et dans l'environnement. Cette valve peut être utilisée dans des récipients de stockage tels que des sachets de stockage d'aliments.
