Abstract (en)
[origin: WO9401346A1] A dispenser (Sp) for pasty materials (3), such as tooth paste, has a head piece (7) with an outlet (4) and an actuating surface (6). A transport piston (8) gradually wanders under air pressure in the direction of the outlet (4) and pushes the material (3) before it with its front side (9). In order to obtain a simple design and a reliable operation of the dispenser, the transport piston (8) is moved by an air overpressure (zone D) that accumulates behind the transport piston (8) when the dispenser is actuated.
