Abstract:
A glue stick comprising:(a) an outer sleeve for receiving a rod-like adhesive mass, the outer sleeve being open at a first end of the glue stick and being closed at a second end of the glue stick by a closure wall through which a bearing sleeve passes having tapered retaining lips provided on an end of the bearing sleeve and extending toward the first end of the glue stick and a conically widened introduction on the other end of the bearing sleeve offset from the closure wall and being surrounded by an outer bearing sleeve extending from the closure wall; (b) a threaded spindle mounted through the bearing sleeve and being interactively connected to a rotary cap arranged on the outer bearing sleeve of the second end of the glue stick, wherein the threaded spindle is attached to an annular thickening which, in the assembled condition, is retained by the retaining lips; and (c) a piston running on the threaded spindle, the piston being rotationally secured with respect to the outer sleeve so that a rotary actuation of the rotary cap effects an axial displacement of the piston, wherein the piston comprises a receiving holder facing the first end of the glue stick and a threaded sleeve facing the second end of the glue stick, and wherein the rod-like adhesive mass extends within the receiving holder to contact the threaded spindle, wherein the ratio of the inner diameter (Ad) of the outer sleeve to the length (AL) of a part of the outer sleeve which serves for receiving the rod-like adhesive mass lies in the region of 1:6 to 1:15 and the threaded spindle is configured as a conveyor worm in order to transport the rod-like adhesive mass in the outer sleeve in an advancing or retreating manner.
