ABSTRACT:
An aerosol spray dispenser system for use with a container having both product and propellant under pressure and in vapor and liquid phases, including a valve unit in which there are separate product and propellant passages, preferably valved by a single gasket, leading from the container to an impact mixing chamber disposed within the valve unit. Here streams of liquid and propellant impact one another to form a fine dispersion of vapor in liquid which is then discharged. Preferably a venturi constriction is disposed in one of the passages just upstream of the mixing chamber. In certain embodiments the chamber and venturi are disposed in the valve housing or in the valve stem; in others they are disposed in the valve actuator contiguous to the discharge orifice; and in still other embodiments they or either of them may be in both locations.
