  • Patent number: 4543148
    Abstract: A prepackaged dispensing system for a two part permanent adhesive including an adhesive portion and an activator portion. The adhesive portion is housed in the main hollow body of a syringe-like member between an initially closed discharge means end and a sealing piston initially spaced axially form said discharge means end. A removably capped elongated dispensing container, adapted to contain and dispense the activator portion, is telescopically positioned within the hollow body and engages the piston. The combined total axial length of the piston and dispensing container when aligned exceeds the internal length of the hollow main body whereby axial pressure on said container will move said piston and insures substantially total discharge of said adhesive by movement of said piston to the discharge end of said hollow body.
