<p>A dispenser for delivering a pasty compound (3) comprises a tubular housing (1) and a plug-in cartridge (2) associated therewith in an axially displaceable fashion, the section (1') of the cartridge that projects beyond one end of the housing having an actuating surface (4) and the delivery mouthpiece (6). A plunger (9) is moved stepwise in the direction of the mouthpiece upon actuation. The advance of the plunger, which is guided by the plug-in cartridge, is achieved by means of displacement of said cartridge against a support plate (10) of the housing, which plate is resettable in the direction of the delivery mouthpiece. The resetting may be achieved by means of a locking connection (80/81) between the plunger and the support plate, the latter being seated on a column (5) that is extensible, the column being constituted by parts that can be telescoped with respect to one another. <IMAGE></p> |
