DEFINITION

Classification: 222/377

(under subclass 372) Dispensers in which the inlet to the discharge assistant casing extends into a supplemental or trap chamber communicating with the supply chamber.

(1) Note. The trap chamber may be formed by baffles or walls within the supply chamber, or by a depression in the bottom wall (including conical bottom walls).

(2) Note. These are for two general purposes, i.e., (1) to be able to substantially completely exhaust the supply, and (2) to be able to trap a small amount about the force feeder inlet so as to be able to dispense same even though the main body of the supply is not about the inlet due to tipping of the dispenser.
