Abstract
A consumer product passage incorporating a mixing chamber for mixing air and liquid. Consumer packages of the present invention are capable of providing excellent spray qualities at typical consumer product flow rates (e.g., less than about 1.0 cubic centimeters per second) while simultaneously maintaining relatively low air to liquid ratios (e.g., less than about 0.06:1 on a mass basis) and relatively low pressures (e.g., less than about 50 psi). The package of the present invention also offers significant environmental and safety advantages. For example, it does not depend upon dissolved propellants; and it permits the use of water in place of volatile solvents as thinning agents since high surface tension fluids are actually sprayed better. Several packages of the present invention are illustrated, including a standard aerosol version, pump and spray versions, and a finger pump version.
