Abstract
A valve closure for a keg, e.g. incorporating an A-type valve arrangement, has a gas inlet port 11, a liquid dispensing port 12 and a valve member 6 to sealably close the gas inlet and liquid dispensing ports. A venting mechanism includes a detent 23 which can be activated by rotating the valve member 6 after the keg has been filled. This mechanism, when activated, primes a resiliently deflectable circumferential arm 22 to move the detent between the sealing face of the valve member 6 and its valve seat when the valve is next connected for dispensing. When the mechanism is not activated it does not interfere with the normal opening and closing of the valve, e.g. during filling
Claims9
A valve closure:
- a closure body (1) for attachment to a container,
- a gas inlet port (11),
- a liquid dispensing port (12),
- valve means to sealably close the gas inlet and liquid dispensing ports, said valve means including an axially movable valve member (6) having a sealing face (28) which is co-operable with a valve seat (9) formed by an annular wall (2) to sealably close the gas inlet port;
- a detent (23) movable into a venting position in which the detent prevents the valve means (6) from sealably closing the gas inlet port;
- characterised in that, in said venting position, the detent (23) is interposed between the sealing face (28) and the valve seat (9).
A valve closure according to 5 wherein the detent (23) is carried by a resiliently deflectable arm (22) which extends circumferentially about said valve member (6), and the retainer (34) holds the detent (23) in the inoperative position by engagement with the resiliently deflectable arm.
