Abstract A manually deformable container utilizes air pressure resulting from squeezing the container to project a jet of liquid. Some of the pressurized air is ejected around the liquid jet to assist in atomization. A nozzle unit is supported on a transverse perforate plate preferably interposed between the container and a threaded closure member defining an air-discharge orifice around the end of the nozzle. Alignment of the nozzle with respect to the orifice is provided by either a lateral shiftability of the plate, a self-centering action of the plate in the container, or by a diaphragm deflection of the plate as the nozzle may tilt in finding its own way into the air orifice. An axial diaphragm deflection of the plate is used to provide a resilient seal of the liquid nozzle by tightening a screw cap against a projecting end of the nozzle, preferably followed by a sealing of the air orifice as the cap is further tightened. Leakage seals in air and liquid passages are provided, and also a container configuration facilitating dispensing in inclined positions of the container without interference with the air-liquid dispensing ratios.
An atomizing liquid dispenser including a manually defomable container having an opening, and a closure member for said opening provided with a discharge orifice, and also including a liquid-dispensing nozzle operative to discharge liquid via a liquid outlet through said orifice, and a cap extending over said orifice and the end of said nozzle, said orifice and nozzle defining between them an air passage communicating with said container, wherein the improvement comprises: a transverse perforate plate supporting said nozzle, (a) said plate being interposed between said container and said closure member, (b) said nozzle having a portion containing said outlet normally projecting outwardly beyond said closure member, (c) said cap and closure member being in threaded engagement, and (d) said plate being resilient as a diaphram to a degree such that manually tightening said cap induces at least partial retraction of said nozzle within said orifice, and resilient closure of said outlet and subsequent closure of said orifice around said outlet.
