(under the class definition) Dispenser having means to direct a flow of fluid into contact with the material to be dispensed so that the fluid picks up material and carries the same to or through the container outlet.
(1) Note. The fluid flow arrangement may be completely exterior of the container, and container contents may be delivered to the flowing fluid in any way, as by gravity, by aspirating action, by an agitator, by force feed, etc. There must be means to direct the flow either of the fluid to the material or of the material into the fluid current. Mere creation of fluid pressure in a supply container is in the appropriate following subclasses.
(2) Note. Where the fluid does not entrain the material to carry it to a place of delivery but agitates or applies pressure to the material to cause discharge, it is not in this or the indented subclasses, but in the appropriate following subclasses.
SEE OR SEARCH THIS CLASS, SUBCLASS:
3+, for a gas or vapor dispensed by itself, i.e., does not carry another material to the delivery place.
195, for gas agitation of the material to be dispensed.
394+, for fluid pressure discharge without entraining the dispensed material.
464.1+, for dispensers comprising a container and internally extending outlet pipe so arranged that suction is necessary to cause discharge. 617, for ambulant dispensers having fluid flow discharge means.
