Abstract
La présente invention concerne des soupapes de décharge unidirectionnelles dotées d'une structure offrant une fonctionnalité d'ouverture et de fermeture à haute pression. Des soupapes des types décrits dans la présente invention peuvent être appliquées à un emballage de produit à parois souples, par exemple un emballage contenant du café torréfié à sec, pour permettre à du gaz de s'échapper de l'emballage tout en empêchant une entrée d'air ambiant dans l'emballage. La structure de soupape fournit une soupape haute pression qui, à la fois, s'ouvre et se ferme à haute pression à l'intérieur de l'emballage. La structure de soupape élimine ou réduit une dilatation excessive de l'emballage à parois souples causée par des augmentations de pression à l'intérieur de l'emballage et élimine ou réduit une contraction ou un écrasement excessif(ve) de l'emballage à parois souples causé(e) par des augmentations de la pression ambiante à l'extérieur de l'emballage, ce qui permet d'obtenir un emballage esthétiquement amélioré tout en maintenant également la qualité du produit emballé.
