An aerosol dispenser having a transparent container for storing a propellant and a first compound under pressure. An actuator button normally closes a valve 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 along the bottom of the container with a saddle shaped foot. A push rod extends from the valve and holds the foot in engagement with the ampule and breaks the ampule when the valve is first moved to its open position. The materials are mixed within the container and are dispensed through a filter mounted on a dip tube leading to the valve.

A method of storing and subsequently dispensing a two component material comprising: storing one component of the material in an enclosed chamber of a container with a normally closed valve means, continuously subjecting said one component of the material to pressure of a propellant, storing the other component of the material in a frangible ampule located in said enclosed chamber of the container opening said normally closed valve means and breaking said frangible ampule within said enclosed chamber, mixing the two components of the material within said enclosed chamber, preventing escape of the material and propellant from the open valve means and enclosed chamber during the breaking of the frangible ampule and mixing of the two components of the material, and dispensing said mixed components of the materials and propellant to a desired location. An aerosol dispenser comprising: a container having a bottom wall, an open top, and a chamber for storing a propellant and first material under pressure, a cap mounted on the container closing said open top, a housing extended into the chamber through said open top, said housing having a passage, control valve means mounted on the cap and housing operable to control the flow of propellant and material from said passage, said control valve means being normally closed and having a movable tubular member extended into the passage which can be moved to open said valve means whereby propellant and materials are dispensed from the container through said tubular member, button means mounted on the tubular member to close said tubular member, a dip tube connected to the housing extended to the bottom portion of the chamber for carrying propellant and materials to the passage, a porous filter mounted on the dip tube to prevent foreign particles from flowing into the passage whereby when said valve means is open the propellant and materials in said chamber flow through the filter and dip tube into the passage, frangible ampule means located within said chamber adjacent the bottom wall, said ampule means storing a second material separate from the first material until the ampule means is broken, means for holding the ampule means adjacent the bottom wall, rod means connected to the movable tubular member and means for holding the ampule means whereby when the movable tubular member is first moved by applying force on the button means the valve means is opened and the ampule means is broken whereby the second material is mixed with the first material in said chamber and said mixed materials flow through the open valve means into the tubular member whereby said button means prevents dispensing of material from the tubular member.
