Abstract

A dispenser for pasty or flowable media comprises a container with a delivery opening, a piston displaceably guided in the container on the wall thereof and forming the lower seal for the filled material, as well as a guide part formed by the container wall on the otherside of the piston. To permit a portionwise or continuous delivery of the filled material, the container is provided on its guide poart with an axially parallel, downwardly open slot corresponding to the total stroke of the piston and a double-walled slide is provided for the displacement of the piston and which roughly corresponds to the slot length and whose two walls engage on the container wall externally or internally on either side of the slot and whose inner wall is connected at its upper end to the piston and at the lower end to the outer wall.
