Abstract
An aerosol dispenser having a transparent container for storing a 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 of the length of the container with a sleeve. A push rod connected to the valve has an inclined shoulder that cooperates with an edge of the sleeve or a ring to break the ampule when the valve is first moved to its open position. The push rod alternatively pivots an angle member pivotally supported on the sleeve to break the ampule. The materials are mixed within the container and are dispensed through a filter mounted on a dip tube leading to the valve.
