Abstract
A disperser 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 diagonally along the length of the container with a holder. A push rod connected to the valve and extended through a generally cylindrical filter surrounding the valve has a conical shaped finger having a lower pointed end engageable with the side wall of the ampule 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 holder has a plurality of vent holes allowing thorough mixing of the materials and free flow of the materials to the valve. The mixed materials and propellant are dispensed through a spout of a nozzle member mounted on the container when the nozzle member is depressed causing the valve to open.
