Abstract
A closure (100) for a keg (14) comprises a housing (160) and at least one valve element (210) that is movable with respect to the housing. The closure also comprises a lock mechanism having a locking element (215) that is movable with respect to the housing and is capable of holding the valve element (210) in the open state. The lock mechanism includes first and second couplings (503, 505) at which the locking element (215) and the valve element are mutually engageable. When the locking element and the valve element are engaged at the first coupling, the locking element moves with the valve element as the valve element moves from the open state into the closed state. This movement of the locking element enables engagement between the locking element and the valve element at the second coupling (503), which engagement at the second coupling occurring on subsequent movement of the valve element into the open state to prevent the valve element returning to the closed state.
