Abstract
A self-contained, hand-held spray dispensing device includes an internal source of pressurized fluid that exerts a motive force on a pair of liquid ejecting elements to cause each to eject a liquid into a discharge line. The liquids remain separated until each exits its discharge port. A pressurized fluid is directed over the outlet ends of the discharge line beginning before a flow interrupter in the discharge line is opened to permit flow therethrough and ceasing after liquid flow is terminated. The pressurized fluid flow over the outlet of the discharge line aerosolizes liquids emanating from the outlet ends. Each liquid ejecting element takes the form of a piston disposed within a cylinder. The pistons responds to pressurized fluid imposed directly thereon from the source to generate the motive force on the ejecting element.
