ABSTRACT:
A liquid sprayer with two side-by-side containers, an interconnecting bridge, and a nozzle insert positioned interiorly of the bridge. Alternatively, a two container piggyback liquid sprayer, a button actuator and a nozzle insert positioned interiorly of the button. One container is for product such as paint, etc., and the other container contains propellant. Very high product/propellant ratios are obtained. An intermediate portion of the nozzle insert has a venturi constriction with an internal propellant outlet orifice. Two product channels transverse to the nozzle insert longitudinal axis overlap the internal outlet orifice by approximately one-half. An outer frustoconical surface surrounds the internal venturi constriction outlet. An expansion chamber diameter is greater than the diameter of both the venturi constriction outlet orifice and the outer frustoconical surface adjacent this orifice. The venturi constriction outlet orifice is longitudinally spaced from the expansion chamber a distance to substantially prevent the propellant gas cone passing into the transverse product channels. The transverse product channels are quasi-rectanglar with areas greater than the venturi constriction outlet orifice. Internal bridge or button spaces extend about the intermediate portion of the nozzle insert. Other significant dimensional relationships are set forth.
