A plastic pressure container has an essentially cylindrical container body with an opening closable in a pressure-tight manner by a valve attachment for dispensing a filling product. An interior plunger is arranged in a longitudinally displaceable manner along a longitudinal axis to subdivide the container body into a receiving chamber adjacent to the opening for the filling product and into a separated reservoir in a pressure tight manner, for a pressure medium. The plunger includes two circumferential sealing lips separated in the axial direction. An upper sealing lip extends into the receiving chamber and a lower sealing lip extends into the reservoir, and these are pressed in a fluid-tight manner onto an inner wall which delimits the interior of the container body, by pressure in the receiving chamber and reservoir.
