Abstract:

A fluid transfer system including a cap member having a first fluid transfer member therein and being removably mountable on a second fluid transfer member. Cooperating lugs and slots formed by the cap member and second member lock the two members together when the cap is placed on the second member and rotated relative thereto. A resilient annular gasket is disposed between the second member and cap member and surrounds the liquid passageway therethrough to prevent leakage. The second member and cap members form an annular space on one side of the outer peripheral portion of the gasket, and an annular bead presses against the other side of the outer peripheral portion of the gasket so that the bead bends that portion of the gasket into the annular space to effect a liquid-tight seal on both sides of the gasket. In the preferred embodiment, the locking lugs are formed on the second member which fits inside the cap member, and the locking slots formed by the cap member extend radially through the wall of the cap member so that the cooperating lugs on the body member are visible through the slots. The slots form cam surfaces which force the cap member tightly onto the second member, and locking notches adjacent the ends of the cam surfaces for holding the cap member in a predetermined locked position.
