DEFINITION

Classification: 222/486

(under subclass 485) Dispensers having the discharge controllers and/or closures operable to expose or control certain groups of the outlets selectively or having them relatively operable or adjustable individually either by adjustment of the actuators or by additional discharge controllers and/or closures.

SEE OR SEARCH THIS CLASS, SUBCLASS:

142.7, for plural compartment dispensers having plural, relatively movable outlet valve means.

283, for plural discharge volume varying means for discharge assistants.

485, where only provision for variable discharge is due to the simultaneous movement of all of the flow controllers and/or closures to less than their fully open position.
