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 means of 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.
