In the outer sleeve there runs a threaded spindle which is mounted in a bearing sleeve ( ) and on which a piston ( ) is movable up and down. The outer sleeve ( ) is in relation to its inner diameter A considerably longer than with known glue sticks. The ratio of the inner diameter A of the outer sleeve ( ) to the length A of the part of the outer sleeve which serves for receiving a rod-like adhesive mass ( ) here lies in the region of 1:6 to 1:15. This however according to the invention demands that the threaded spindle is configured such that it simultaneously serves as a conveyor worm. Thanks to the special configuration of the piston ( ) is spite of the great length of the threaded spindle there is achieved a bending-breakage stabilization.

Glue stick

The invention relates to an adhesive stick having a plunger anchoring the stick composition and a sleeve surrounding the stick composition, in which the propelling device for the upward and downward moving of the stick composition, which device at the same time serves as the actuating element, is formed together with the sleeve and the plunger as a one-part injection moulding. This propelling and actuating element (1) is designed in the form of a plate and is provided with lateral reinforcing webs (2) and is bonded on both sides to the plunger plate (0); it has at the vertex a pressure plate (3). Anchorage elements for the stick composition on the plunger plate (0) are designed in the form of bristles (6).
