DEFINITION

Classification: 239/340

(under subclass 337) Apparatus provided with means whereby a drop in pressure is produced at the outlet of the receptacle whereby the material is aspirated or sucked into the pressure fluid medium or carrier fluid.

(1) Note. The holder outlet is here interpreted to be the point at which material enters the carrier stream, usually at the eduction tube terminus even though remotely positioned relative the holder proper.
