An improved aerosol dispenser is disclosed for mixing and dispensing a first and second fluid. The improved aerosol dispenser comprises a valve body sealably mounted to the aerosol container. A first and a second channel is defined in the valve body for providing fluid communication with a valve body cavity of the valve body. A first and a second inner container are located within the aerosol container for communicating with the first and second channels, respectively. A valve assembly comprising a first and a second valve element enables the mixing and dispensing of the first and second fluids from a terminal orifice upon the simultaneous actuation of the first and second valve elements. The invention is also incorporated into the process of filling an improved aerosol dispenser with a first and a second fluid products and an aerosol propellant.
