Abstract: Improved hand-held, hand-powered spraying devices are provided herein. The improvement provides the ability to spray viscous fluids in an even consistent spray without the use of propellants or outside compressed air or power sources. The spraying apparatus are constructed to provide air delivery to a nozzle assembly, followed by combined air and liquid delivery, followed by air delivery after cessation of liquid delivery, all with a single stroke of a single trigger. One particular apparatus provided is a trigger sprayer which utilizes the compression of dual chambers with a single trigger stroke, and another apparatus is a compression sprayer which utilizes a hand pump and a single container for holding air and liquid. Additionally, a combination pour spout trigger sprayer device is provided.

Abstract: A METHOD AND APPARATUS FOR ATOMIZING AND SPRAYING LIQUIDS SUCH AS FUEL, PAINT OR WATER IN THE FORM OF MINUTE DROPLETS UTILIZING A SMALL AMOUNT OF AIR TO PROVIDE THE ATOMIZING FORCE. THE LIQUID UNDER A PRESSURE OF FROM 30-100 PSI IS CAUSED TO FLOW IN A THIN FILM. STREAMS OF GAS AT A SLIGHTLY HIGHER PRESSURE ARE INPINGED AGAINST THE LIQUID FILM SO THAT THE GAS IS SHEARED INTO MICROBUBBLES WHICH ARE ENTRAINED IN THE LIQUID TO FORM A FROTH IN WHICH THE LIQUID IS THE CONTINUOUS PHASE, AND IN WHICH THE AIR TO LIQUID MASS RATIO IS FROM 0.1 TO 1.6. THE FROTH FLOWS THROUGH A SPACE IN WHICH THE PRESSURE DECREASES AS THE FROTH MOVES TOWARD A NOZZLE. DURING THIS FLOW THE FROTH BECOMES HOMOGENEOUS. THE FROTH IS DISCHARGED THROUGH A NOZZLE WHEREUPON THE AIR BUBBLES EXPLODE RUPTURING THE LIQUID FILM AND CAUSING THE LIQUID TO DISINTEGRATE INTO FINELY ATOMIZED

DROPS. THE APPARATUS FOR CARRYING OUT THIS METHOD COMPRISES A LIQUID FILM-FORMING CHANNEL CONNECTED TO A LIQUID INLET LINE SUPPLIED WITH LIQUID UNDER PRESSURE, AN AIR INJECTION CHANNEL TERMINATING ADJACENT TO THE LIQUID FLOW CHANNEL, A FLOW SPACE INTERCONNECTING THE LUQID FILM CHANNEL AND A NOZZLE ORIFICE. IN THE PREFERRED EMBODIMENT THE FILM-FORMING CHANNEL IS ANNULAR WITH AIR BEING INJECTED FROM THE OUTSIDE OF THE CHANNEL. IN A MODIFICATION THE LIQUID FILM-FORMING CHANNEL IS PLANAR WITH AIR BEING INJECTED INTO THE FILM FROM ONE OR BOTH SIDES OF THE CHANNEL.
