A device for dispensing measured amounts of a single-component or multi-component substance, such as an adhesive material, a sealing material or a filler material, includes a container holding the substance. A cartridge of propellant gas is positioned within the container and is arranged to supply the propellant gas into contact with a piston which is displaceable in the container for dispensing the substance.

Device for dispensing measured amounts of a single-component or multi-component substance, such as an adhesive material, a sealing material or a filler material, comprising a container for the substance to be dispensed, said container is elongated having a first end from which the substance is dispensed and a second end, a piston located within said container and extending transversely of the first end-second end direction, said piston is displaceable in the first end-second end direction toward the first end for dispensing the substance out of said container, means for introducing a pressurized propellant into contact with the piston for displacing said piston toward the first end of said container, said means comprising a replaceable cartridge of a gasous propellant, said cartridge is located within said container and is separated from the part of said container holding the substance to be dispensed, said cartridge includes an outlet valve for discharging the gaseous propellant out of said cartridge, said container and said cartridge therein in combination with said piston forming a space between said piston and the second end of said container for receiving the gaseous propellant from said outlet valve so that the gaseous propellant acts on said piston for displacing said piston toward the first end of said container, a casing for holding the second end of said container, a flexible elastic member forming a closure across the second end of said container, means mounted within said casing for displacing said closure inwardly into said container for opening said outlet valve.
