DEFINITION

Classification: 220/203.07

Valve operated by distinct actuator or closure:

(under subclass 203.04) Device wherein the manually operable means includes a separate implement, such as a push rod or a pivoted arm on the closure, which is mechanically coupled to the venting or valving mechanism. Operation of said implement causes the venting or valving function to be performed.

(1) Note. When a mechanism is provided on the receptacle closure which serves the sole purpose of adjusting the pressure at which the valve will operate, the invention will be classified in subclass 203.04 above.
