Abstract
A multiple dose paste dispenser has a frame with a handle secured thereto. A piston rod having a piston on the front end is mounted in said frame for longitudinal movement. A cartridge is secured to the frame in alignment with the piston. A gripping ring is slidable along said rod and grippably engages the rod when it is tilted with respect to the rod. A return spring urges the ring in a direction away from the piston. A trigger pivotally mounted on the frame is adapted to tilt the ring and advance the ring, the rod and the piston into the cartridge. A stop is pivoted to the frame for movement from an inoperative position to a position for limiting the advance of the ring. Advantageously the stop is stepped to provide for at least two different stop positions.
