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.
