Abstract
A glue stick with a piston supporting the stick substance and a shell surrounding the stick substance is disclosed. A drive mechanism for up and down movement of the stick substance is formed in the nature of a piston connecting rod coupled to the piston, which at the other end is coupled to an actuating element which can be actuated from outside the shell. The drive element can be formed as a rod (2, a, 30, 40, 52) or as a flexible band (2C). The actuating element can be formed as a double ring (3), as a toggle joint (17), as a tongue shaped double wheel (32), as a wheel (41), or as a semi-circular solid wheel (53). preferably formed as a one-piece injection moulding. For assembly of the glue stick is pushed in to the shell from the open side, and then the glue stick substance is poured from above into the hollow space of the shell, becoming anchored on or in the piston when it set.
