Abstract
A dispensing device for applying a pasty substance, for example to a human hair, comprises a cup-shaped cylindrical container and a piston located therein and displaceable within the container. The container is sealingly connected to an operating extension having a cylindrical passage terminated with a dispensing nozzle which is selectively closed by a sealing cap. The piston is formed with two sealing lips spaced from one another in the axial direction and outwardly and angularly extending from the periphery of the piston so that one of the lips sealingly connects the piston to the internal wall of the container whereby the second lip is adapted to reliably guide said piston within the container.
