Abstract: A cartridge system for an eccentric screw pump, comprising a cartridge for receiving a medium to be dosed, a stator being provided on the cartridge, which cooperates with a rotor unit of the eccentric screw pump for dosing the medium, and a plug being movably supported in the cartridge for a fluid-tight closure of the cartridge, wherein the plug comprises a rotor breakthrough through which the rotor unit can be passed.

Abstract: The invention relates to a furniture system, in particular a kitchen furniture system consisting of a self-supporting basic framework with tubes and/or sections connected to each other by connecting elements. In accordance with the invention the connecting element has a shaped part which is itself formed as a tube and/or substantially closed hollow section on which at least one laterally protruding projection is formed extending over the whole length of the connecting element and that the connecting elements themselves are integrated as vertical components which replace the tubes and/or sections in some parts in the basic framework.
