DEFINITION

Classification: 222/257

(under subclass 256) Dispensers in which the tubular outlet through which the material is dispensed is movably mounted on the dispenser, which tubular outlet is interconnected with at least one of the two discharge assistants (follower or casing enclosed impeller) as defined in subclass 320.

(1) Note. Where the nozzle is so mounted on the dispenser as not to be movable relative thereto, it is not in this or the indented subclasses, even though the nozzle is made of flexible material (as a hose) and is capable of motion due to this fact. Also where the nozzle is movably mounted on the dispenser, but the defined interconnection is not present, it is not in this and the indented subclass, but in other appropriate subclasses.
