An aerosol spray dispenser is disclosed that includes an outer housing that is circular, oval, or non-oval and in which an active composition to be dispensed is provided and a closure sleeve housing within the outer housing. An inner receptacle is provided within the closure sleeve housing and within the volume of the outer housing and contains a propellant to be dispensed. The inner housing may be concentrically located within the outer housing. An actuator assembly houses a nozzle that has a venturi constriction. A tube extends within the outer housing to provide the passage of active composition from within the outer housing by the venturi effect. A conduit for the passage of a propellant from the inner receptacle to the nozzle is provided. The propellant and the active composition are mixed and dispensed as a spray at a nozzle by action of the venturi effect. Materials that are not compatible with the active composition can be added to the propellant and effectively mixed and dispensed, for example a fragrance that is incompatible with hypochlorite or one component or a two part hardening composition.

What is claimed is: 1. An aerosol spray dispenser comprising, an outer housing defining a volume and containing an active composition to be dispensed, an inner housing within the volume of the outer housing and containing a propellant receptacle containing a propellant to be dispensed, a nozzle having a venturi restriction, a tube having a first end extending into the outer housing and having a second end, an over-cap enclosing the outer housing and having a manual actuator, an actuator assembly which houses the nozzle and includes a propellant conduit for the passage of the propellant from the propellant receptacle within the inner housing to the nozzle, an active composition conduit extending from the second end of the tube to the nozzle, and a responder which is engaged by the manual actuator allowing the propellant to pass through the propellant conduit and allowing the active composition to pass through the active composition conduit, both to the nozzle, where the propellant and the active composition are mixed and dispensed. 2. The aerosol spray dispenser of claim 1 wherein the outer housing is cylindrically-shaped. 3. The aerosol spray dispenser of claim 1 wherein the outer housing is not cylindrically-shaped. 4. The aerosol spray dispenser of claim 1 wherein the outer housing is made of plastic. 5. The aerosol spray dispenser of claim 1 wherein the inner housing is cylindrically-shaped. 6. The aerosol spray dispenser of claim 1 wherein the inner housing is made of plastic. 7. The aerosol spray dispenser of claim 1 wherein the inner housing is generally concentrically positioned relative to the outer housing. 8. The aerosol spray dispenser of claim 1 wherein the manual actuator is a resilient member formed as an integral part of the over-cap. 9. The aerosol spray dispenser of claim 1 wherein the propellant receptacle additionally contains a material that is non-compatible with the active composition. 10. The aerosol spray dispenser of claim 9 wherein the non-compatible material is selected from the group consisting of surfactants, buffers, fragrances, antiallergenic compounds, air disinfectants, deodorizing compounds, and combinations thereof. 11. The aerosol spray dispenser of claim 1 wherein the active composition comprises hypochlorite. 12. The aerosol spray dispenser of claim 9 wherein the active composition comprises hypochlorite. 13. The aerosol spray dispenser of claim 1 wherein the active composition is one of the two components of a two part hardening composition and wherein the propellant includes the other of the two components.
