  • Patent number: 5477980
    Abstract: A receptacle cover is disclosed incorporates an actuating trigger connected to a pair of biased valves that seal off the dispensing conduit and the relief vent from the top side of the cover. This construction isolates most of the linkage between the valves and the actuator from the contents of the receptacle. The actuator is a trigger located proximate the upper portion of a handle extending from the cover, and is linked to the valves by a wire that extends to, and moves, a rotating rod that is perpendicularly disposed in relation to the wire. The rod, in turn, is attached to the valves by additional wires that force them open against their proximate leaf springs. The dispensing conduit forms a plenum or chamber that functions in a manner similar to a straw by extending upwards from the cover. This construction prevents inadvertent leakage or fluid build up on the exterior of the receptacle.
