DEFINITION

Classification: 222/265

(under subclass 252) Dispensers having plural discharge assistants all of which perform substantially the same function and have similar structure, so that the general effect is duplication of dispensing units.

(1) Note. Such means may be of unitary structure where it provides plural separate discharge paths even though they all deliver to a common outlet, but a unitary device which both provides a single discharge path and delivers to a single outlet is classified as a single discharge assistant.

(2) Note. Plural discharge assistants which are alternatively usable only may be considered to be in sets if they have similar structure. If the structures are dissimilar, see subclasses 278+.

(3) Note. Plural discharge assistants, even though they move in different directions, which are so related as to form a single outlet between them and thus move material therethrough in the same general direction are not considered to be in sets, see subclasses 280+.

(4) Note. Discharge assistants having plural vanes or blades movable as a unit and all of which move the material in a single discharge path to a single outlet are not considered to be plural discharge assistants.

(5) Note. A single rotor having plural vanes is regarded as being in sets only if each has a separate discharge outlet associated with it. SEE OR SEARCH THIS CLASS, SUBCLASS:
