Abstract
A dispenser for discharging a flowable medium, having an elongate storage container which receives the flowable medium, has an essentially constant inner cross-section, bears a manually actuable, suction-type discharge device at the top and contains a follow-on plunger which forms a base in the storage container and is in close contact with a dischargeable quantity of free-flowing medium. In order to provide a dispenser of the abovementioned type which is of simple construction and is subject to low wear, it is provided that the plunger is made up of a circumferentially closed-cell flexible foam, which has little or no capacity for adhesion, and is provided with a slightly oversized circumferential surface with respect to the inner cross-section of the storage container, with the result that the plunger can slide along the inner wall of the storage container.
