ABSTRACT:
A spray dispensing device is provided which can be used with non-pressurized containers. The device includes passageways for directing streams of air and liquid to a mixing chamber wherein the liquid is broken up into droplets and emitted as a fine spray through an orifice. An annular air passageway is concentrically disposed around a liquid passageway, both of which lead to the mixing chamber wherein the annular stream of air will be deflected by tapered walls of the mixing chamber to converge and impinge open the core stream of liquid, at a point in proximity to the orifice. The device may include a dip tube for the liquid which is provided with a check valve for retaining liquid at a high level in the dip tube after each spray cycle so that spraying is nearly instantaneous upon actuation.
