DEFINITION

Classification: 141/71

(under subclass 69) Apparatus in which the density of the fluent charge in the receiver is increased (1) by compacting or agitating within the receiver or (2) by increasing the density of the contents charge after it has been separated from the supply, the material being confined until it enters

the receiver.

(1) Note. Deaerating of fluent materials is considered a compacting operation.

(2) Note. The many discharge assistants and agitating type dispensers which inevitably produce a compaction of loose material as an incident to handling have not been made a basis for classification in this class but have been cross referenced to appropriate subclasses in Class 222, Dispensing.
