Title
(EN) CONTAINER WITH A LEAK-PROOF CHECK VALVE
(FR) RÉCIPIENT COMPORTANT UN CLAPET DE NON-RETOUR À L'ÉPREUVE DES FUITES
(ZH) 防泄漏单向阀容器
Abstract
(EN)
A container equipped with a leak-proof check valve; the container comprises a gas-liquid separation and filtration device between the inlet of the check valve (1) and the content (9) of the container, isolating liquid and solid substance inside the container from the inlet of the check valve (1) via a waterproof breathable membrane (2) or larger area on the device while allowing a large quantity of gas to penetrate, thus achieving leakage prevention of liquid and/or solid powder from within the container while relieving gas and preventing gas from returning. The container equipped with the leak-proof check valve can be used for packaging, storing and transporting various powder- or liquid-containing substances that generate gas and must be isolated from oxygen.
(FR)
L'invention porte sur un récipient qui comporte un clapet de non-retour à l'épreuve des fuites ; lequel récipient comprend un dispositif de séparation et de filtration gaz-liquide entre l'entrée du clapet de non-retour (1) et le contenu (9) du récipient, isolant le liquide et une substance solide à l'intérieur du récipient à partir de l'entrée du clapet de non-retour (1) par l'intermédiaire d'une membrane (2) perméable à l'air et étanche à l'eau, ou d'une plus grande surface sur le dispositif, tout en permettant à une grande quantité de gaz de pénétrer, de façon à obtenir ainsi une prévention des fuites de liquide et/ou de poudre solide à partir de l'intérieur du récipient tout en libérant les gaz et en empêchant les gaz de revenir. Le récipient comportant le clapet de non-retour à l'épreuve des fuites peut être utilisé pour emballer, stocker et transporter différentes substances contenant une poudre ou un liquide, qui génèrent des gaz et qui doivent être isolées vis-à-vis de l'oxygène.
