DEFINITION

Classification: 222/443

(under subclass 425) Dispensers having either an outlet other than the trap chamber or having the cutoffs adjustable to provide for free flow through the trap chamber.

(1) Note. Many unitary cutoffs for both inlet and outlet may be held in an intermediate position, permitting free flow of the material, for which see subclasses 451+. When special means is provided for holding the cutoff in such position, the patents are here.
