Abstract

Une soupape de sécurité antiretour possédant un filtre intégré. Les soupapes de sécurité antiretour peuvent être appliquées à un emballage de produit pour évacuer le gaz de lemballage. Le filtre intégré empêche les matériaux à lintérieur de lemballage de perturber la fermeture ou le fonctionnement de la soupape de sécurité. Certains modes de réalisation dune soupape de sécurité peuvent être conçus pour un fonctionnement de soupape optimal sans laide dun agent mouillant alors que dautres modes de réalisation dune soupape de sécurité fonctionnent de manière optimale avec un agent mouillant.
