ABSTRACT:
A reciprocating type of finger pump for use on top of a product container. This combines a tubular housing, including a laterally directed spray nozzle, mounted coaxially in the sleeve of an accumulator cap including a central valve. The valve opening leads to a dip tube which passes into a liquid reservoir in the container. The tubular housing, including the spray nozzle, is depressed manually so that it moves telescopically in the accumulator sleeve, driving a hollow piston against the tension of a spring. The first compression stroke serves to prime the pump, forcing a piston to close the valve to the dip tube. Simultaneously, air in an annular chamber of the housing surrounding the hollow piston is compressed. On the reverse or suction stroke, the valve to the dip tube is opened, creating a vacuum which causes the liquid to be sucked up from the reservoir and into the hollow piston. On the second or subsequent compression strokes, the compressed air and liquid are forced through normally closed pressure responsive seals into the inner mixing chamber, where the compressed air breaks up and atomizes the liquid, causing the atomized spray to move at high pressure through the spray nozzle. Simultaneously, the valve to the dip tube closes, air is drawn into and compressed in the outer annular chamber, and the cycle is ready to be repeated in response to the successive release and reapplication of pressure on the tubular housing. Means is provided in response to rotation of the cylindrical housing relative to the accumulator sleeve for locking the pump against compression for shipping or safety purposes.
