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. The device includes 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.
