DISPENSER FOR FLOWABLE MATERIALS Abstract of the Disclosure A dispenser for flowable materials includes an outer barrel which is telescoped over a plunger. A piston head may be separate and distinct member from the plunger itself and may be prepackaged in the barrel with the material to be dispensed located in a chamber above the piston head. When the barrel is telescoped over the plunger, the piston head seats on the plunger and forces fluid from a dispensing spout in the barrel. The piston head carries a sealing rim which creates a seal as the barrel is moved downwardly on the plunger. The barrel may be in the form of a cartridge mounted in a jacket-like holder with a seal between the cartridge and holder.
