具有安全机构的小桶封闭件
摘要：
一种用于小桶（14）的封闭件（100）包含外壳（160）以及可以相对于所述外壳移动的至少一个阀元件（210）。所述封闭件还包含具有锁定元件（215）的锁定机构，所述锁定元件可以相对于所述外壳移动并且能够将所述阀元件（210）固持在打开状态。所述锁定机构包括第一和第二耦接件（503、505），在所述第一和第二耦接件处所述锁定元件（215）和所述阀元件可互相啮合。当所述锁定元件与所述阀元件在所述第一耦接件处啮合时，随着所述阀元件从所述打开状态移动到关闭状态，所述锁定元件随所述阀元件一起移动。所述锁定元件的此移动实现了所述第二耦接件（503）处所述锁定元件与所述阀元件之间的啮合，所述第二耦接件处的所述啮合发生在所述阀元件随后移动到所述打开状态时以防止所述阀元件返回到所述关闭状态。
摘要（英）：

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.
