Patent ID: 7866512

Claim:
Container system having a pumping mechanism of a container pump, integrated into a container, which mechanism has a pump lance that can be introduced into the container through a tap hole, through which lance a rotor shaft releasably connected with a drive motor, having a pump rotor accommodated on the rotor shaft so as to rotate with it, extends, whereby the pump rotor is disposed at the end that is removed from a drive side of the rotor shaft, therefore is disposed in the bottom region of the container and having a pump head that can be separated from the pumping mechanism, wherein the pumping mechanism ( 11 ), separated from the pump head ( 25 ), is introduced into the tap hole ( 5 ) of the container ( 1 ) in such a manner that the container ( 1 ), with the pumping mechanism ( 11 ) introduced, forms a sealed unit, and the pump head ( 25 ) comprises a connector flange ( 30 ) for a force-fit and shape-fit connection of the pump head ( 25 ) to the pumping mechanism ( 11 ), whereby a removal connector piece ( 33 ) for connecting a pressure hose ( 35 ) for emptying the container ( 1 ) is integrated into the connector flange ( 30 ).
