Abstract
A 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 is movable to break 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. The dispenser is operable to dispense two component epoxy and polyester adhesives as a foam to selected locations.

A dispenser comprising:
- a container having an internal chamber for storing a propellant and at least one first component under pressure, normally closed valve means mounted on said container to retain the propellant and one first component under pressure in said chamber, said valve means includes a housing mounted on the container, said housing having a chamber and a hole in the bottom portion thereof, said valving means further including a valving member located in said chamber for movement in a first direction from a closed position to an open position to dispense aerosol to a desired location and in a second direction from an open position to a closed position to prevent dispensing of aerosol, frangible ampule means located within said chamber containing at least one second component that is separated from the first component within the chamber until said ampule means is broken, means for holding the ampule means in said chamber, and means connected to said valve means and connected to said means for holding the ampule means, said means connected to said valve means and connected to said means for holding the ampule means comprising a rigid push rod extended through said hole in the housing whereby when the valve means is first moved in the first direction the valve means is opened and force is transmitted through the rod and means for holding the ampule means to break the ampule means thereby releasing the second component into said internal chamber whereby the first and second components are mixed together and flow through the chamber in the housing an open means to a selected location.
A dispenser comprising:
- a container having an internal chamber for storing a propellant and at least one first component under pressure, normally closed valve means mounted on said container to retain the propellant and one first component under pressure in said chamber, said valve means being moveable in a first direction from a closed position to an open position to dispense aerosol to a desired location and in a second direction from an open position to a closed position to prevent dispensing of aerosol, frangible ampule means located within said chamber containing at least one second component that is separated from the first component within the chamber until said ampule means is broken, means for holding the ampule means in said chamber, means connected to said valve means and connected to said means for holding the ampule means, said means connected to the valve means and connected to said means for holding the ampule means comprising a rigid push rod whereby when the valve means is first moved to a first direction the valve means is open and forces transmitted though the rod and means for holding the ampule means to break the ampule means thereby releasing the second component into said chamber whereby the first and second components are mixed together and flow through the open valve means to a selected location, said valve means has an outlet passage for the propellant and mixed components, and means for closing the outlet passage to prevent dispensing of aerosol during the breaking of the ampule means, said means for closing the outlet passage being removeable from the valve means after the ampule means has been broken.
A method of dispensing a two component adhesive comprising:
- storing a first component of an adhesive in an enclosed container with a propellant under pressure having a valve moveable from a closed position to an open position;
- storing a second component of the adhesive in an ampule located within said container;
- breaking the ampule by moving the valve to the open position whereby the first and second components of the adhesive are mixed together;
- preventing the escape of the mixed components of the adhesive and propellant through the open valve during the breakng of the ampule;
- and discharging the mixed first and second components of the adhesive with propellant from the container by moving the valve to the open position, said adhesive being as an adhesive foam directed to a selected location.
