ABSTRACT:
The invention relates to a closure unit for a container suited to filling and dispensing a beverage stored under a pressuring gas. The closure unit comprises a bush from which is disposed a tubular element mounting two concentric valves and a siphon tube which extends into the container. The bush is locked into place in the neck of the container by a threaded locking sleeve which sandwiches a deformable ring between it and the bush. The ring and locking sleeve have respective intermeshing saw toothed profiles which allow locking to occur. This prohibits gas flow from the container between the neck and the bush. Upon unlocking, the profile in the ring becomes fractured thereby depressuring the container. The concentric valves are defined by a tubular element which is surrounded by a resilient material which forms a gas seal for the outer of the valves, and which embeds a radially outward extending flange of the tubular element with the resilient material passing through apertures in the flange to form a continuous mass.
