Abstract

La présente invention concerne un perfectionnement apporté aux emballages souples susceptibles d'être soumis à une pression interne supérieure à la pression ambiante. Précisément, elle concerne une soupape faite d'un corps qui peut être un disque à partie centrale tronconique et d'une membrane portant sur ledit corps. La membrane peut être la paroi même du récipient d'emballage. Elle est percée au-dessus d'un siège auquel le gaz peut parvenir par un réseau de canaux qui communique avec l'intérieur de l'emballage par les alésages périphériques. La membrane est ainsi sollicitée sur toute sa surface par une éventuelle pression d'ouverture. La soupape est soudée sur l'emballage. Application à l'emballage de produits alimentaires.
