An aerosol dispenser having a transparent container for storing propellant and a first compound under pressure. A normally closed valve is mounted on top of the container to control the dispensing of the materials from the container. An ampule containing a second material separate from the first material until the ampule is broken is positioned generally longitudinally along the length of the container with a sleeve. A push rod connected to the valve and extended through a generally cylindrical filter surrounding the valve has a convex shaped finger and an inclined shoulder that cooperates with a beveled edge of the sleeve to break the ampule when the valve is first moved to an open position. The materials are mixed within the container and move through the filter before entering the valve. The mixed materials and propellant are dispensed through a nozzle of an actuator member mounted on the container when the actuator member is depressed causing the valve to open.

An aerosol foam dispenser comprising: a container having an internal chamber for storing a propellant and a first material, normally closed valve means mounted on said container to retain the propellant and first material in said chamber, said valve means being moveable to an open position to dispense foam to a desired location, at least one frangible ampule means located in the chamber containing a second material separate from the first material, means holding the ampule means in said chamber generally along the length of the chamber, rod means engageable with the valve means and said means for holding the ampule means, said rod means having an end portion movable between said means for holding the ampule means and the ampule means operable to break said ampule means when the valve means is first moved to the open position thereby releasing the second material into said chamber whereby the first and second materials are mixed together.
