ABSTRACT OF THE DISCLOSURE A piston, lead screw, dispenser rear end wall and twistable projection are assembled together. On the filling line, tubes each with a dispenser spout at one end, are filled through the opposite end and closed by securing the rear end wall of the assembly to the tube as a closure for the open end. In one embodiment the tube and end wall are made of plastic material and the securement is by ultrasonic welding; in another, the tube is of foil/fiber composite, the end wall is of metal and the securement is accomplished by crimping. When the dispenser tip is opened, rotatably twisting the lead screw projection in one angular sense will advance the piston and discharge the tube's filling of caulking compound or the like, that is contained between the piston and the spout.
