  • Patent number: 4089443
    Abstract: An aerosol, spray-dispensing apparatus comprising an outer, sealed container various neutral propellants are stored therein, an inner container having the lower portion thereof compressibly affected by the neutral propellant when the spray head of the spray valve is activated, the head and valve being attached to the outer, pressurized container in a normal manner, wherein the inner container includes an upper, non-collapsible, body member positioned within the pressurized container so as not to be affected by the internal pressure of the propellant gas stored therein. As arranged, the inner container provides a non-contaminated compartment wherein the active ingredient to be discharged is stored and sealed from the gas filled compartment of the outer container, whereby the pressure of the propellant gas therein will only collapse the lower, thin bag portion of the inner container, providing total discharge of the stored ingredient--be it in liquid or powder form.
