The caulking cartridge includes an end closure disc fixed in place at one end of the cylindrical body of the cartridge. The shutoff discharge nozzle comprises a circular base or flange portion seated against the end closure disc and rotatably mounted relative thereto. The dispensing opening formed in the closure disc and the discharge passage in the nozzle, which are radially offset with respect to the axis of rotation of the nozzle by substantially the same distance, may be aligned to permit dispensing of the material or nonaligned to prevent dispensing and drooling of the material upon rotation of the cartridge body relative to the discharge nozzle without removing the cartridge from the caulking gun.
