ABSTRACT:
A spout located on a nozzle of a cartridge containing semi solid material has a movable gate for selectively opening and closing the passage through the spout. The spout has a slot slidably accommodating the gate. An annular bead on the spout surrounds the opening and projects into the slot. The gate has a convex curved portion that engages the bead when the gate is in the closed position to seal the material in the nozzle.
