DEFINITION

Classification: 222/402.1

(under subclass 394) Dispensers in which a valve closing an opening for material under fluid pressure is opened by motion, relative to a wall of the container holding the material, of an actuator which is either (1) a tubular flow guide through which the material passes from the opening toward discharge or (2) a member moving inwardly of the container through the opening.

SEE OR SEARCH THIS CLASS, SUBCLASS:

322, for dispensers with discharge assistants in which an actuator for a movable dispenser part projects through the final dispenser outlet discharging to the atmosphere.
