Abstract
A charge of a condiment such as catsup, mustard or a similar sauce is delivered from a bulk-storage container to a chamber at the end of an air-actuated gun. When the trigger of the gun is actuated to force a piston along the chamber, the charge of condiment is ejected from the gun. When the trigger is released, the piston is retracted toward the rear of the chamber and a new charge of condiment is moved into the chamber under a small amount of pressure from the bulk storage container to a position in front of the piston.
