ABSTRACT:
A portable dispensing appratus which includes a resiliently deformable dispensing reservoir adapted to mount removably on the uppermost end of a dip tube which extends into a bulk container of liquid. The dip tube includes a one-way inlet valve near its lowermost end which prevents flow of liquid out of the dip tube, but which permits flow into the dip tube. Suction created by compressing the resiliently deformable reservoir causes liquid to enter the dip tube through the one-way inlet valve and to flow into the reservoir. The dispensing reservoir can then be removed from the dip tube and taken to a location where it is desired to dispense all or a portion of the liquid. The liquid is dispensed by squeezing the resiliently deformable reservoir, thereby forcing the liquid out through the nozzle. A one-way, pressure-operated outlet valve is preferably located in the dip tube inside the bulk container to permit compression of the resiliently deformable reservoir after placement of the reservoir on the dip tube. The one-way, pressure-operated outlet valve permits return of the bottle of any air and/or unused liquid in the reservoir, thereby ensuring that a full measure of liquid will be drawn into the reservoir for the next dispensing cycle.
