Abstract
Dosing dispenser for flowable media with a pump that may be manually handled and is integrated in a medium container, with a piston ( ), which closes the container ( ) fluid-proof to the outside and with a container that is displaced between an upper position and a lower position. A piston chamber ( ) adjoins the inner chamber ( ) of the container, and is provided in the container bottom ( ). The piston chamber has an open upper end aligned to the piston. A connecting channel ( ) extends through the piston and provides a fluid-communication to the outside of the container. A spring ( ) urges the piston into its upper position, wherein the piston ( ), in its upper position, is situated at a distance from the piston chamber ( ) and immerses during its downwards movement in its lower position into the piston chamber and, at the same time, closes the adjoining inner chamber ( ) of the container from the piston chamber.
