Abstract

A dispenser for pasty compositions (M) having a housing (1) in which there is arranged a piston (2) which is displaceable only in the emptying direction. An outer actuating handle is provided on a wall (10) of the head piece (K). The wall can be pressed in the direction towards the piston, the head piece having a dispenser outlet opening (7) which lies at the outer end (9") of a tube (9) whose end section (9') forms an inner open mouth end the end section over its entire length protruding inwards beyond the wall into the pasty composition. In order to obtain a structural shape which is simple to manufacture and a self-regulation of the delivery which is free of loss the actuating handle is formed as a dome-shaped cap (6) and is seated on a collar (12) which lies concentric to the tube (9) and which collar protrudes outwardly beyond the wall (10). A removable closure lid has a stopper which extends into the dispenser outlet opening. The closure lid is spaced from the cap and is held against an annular wall which extends on the outside of the housing spaced apart from an edge of the cap.
