ABSTRACT:
A dispenser for paste-like materials is described which has a cover that automatically seals the dispenser's spout when no material is pumped therefrom thereby protecting the spout and its immediate surroundings from ambient air. The cover automatically unseals the spout while material is being dispensed. The dispenser includes (1) a housing, (2) a reservoir or replaceable cartridge for storing paste-like material, (3) a pump for causing the flow of a controlled quantity of material from the reservoir or cartridge, through a channel and its discharge from the spout and (4) an integrated, rotatable cover containing a sealing cap for the spout and a plunger for activating the pump. The sealing cap and plunger move in concert with each other so that material is pumped from the spout after the sealing cap moves away from the spout. The dispenser eliminates the need for the manual replacement of caps, seals, plugs, covers and the like and provides an efficient seal which eliminates unwanted caking in the spout caused by dried out material.
