Document Type and Number:
Japanese Patent JP3390953
Kind Code:
B2
Abstract:
A valve assembly, securable in an upper opening of a container for liquids, is simple and inexpensive to manufacture yet provides improved operability and is capable of relieving excess gas pressure within the container. The valve assembly preferably includes a stub and a riser pipe/valving unit detachably mounted in the stub. The valving unit substantially consists of a unified riser pipe having blockable gas and/or liquid portals, and movable members arranged co-axially within two upper reception areas in the riser pipe and including a single sealing ring and a dispensing tower. The sealing ring is axially displaceable against the pressure of a spring to move from a neutral closed position to a lower open position by way of external activation. One of the sealing ring and the dispensing tower is movable axially relative to the other, under lifting forces imposed by excess gas pressure within the container, from a neutral closed position to a venting position, thereby venting some gas from the container and regulating container pressure.
