DEFINITION

Classification: 222/95

(under subclass 92) Dispensers having means other than or in addition to mere manual squeezing or gravity flow to assist or cause discharge of the receptacle contents.

(1) Note. The majority of such means act on the wall structure to collapse the same. Some patents, all in this subclass (95), do not act on the wall structure, such as pumps, with the receptacle connected to the intake, atmosphere pressure causing collapse of the wall, and receptacles having a material follower therewithin, the walls being collapsed by hand.
