In order to place a sealing cap, which is to be placed in particular on a filler neck of a gasoline tank, on the neck so as to preserve the seal with little actuation force but so that it seals securely, the sealing cap is equipped with a turning lifting apparatus (24, 43) which effects a pressing of the sealing ring (4) at the free neck end (5) when the turning stop (26) of the sealing cap encounters the counter stop (27) of the filler neck (1). A pressing member (23) is displaced in the axial direction against the resistence of a compression spring (25) in the turning stop (26) via the turning lifting apparatus and simultaneously moves a radial outer collar which is coupled with the turning handle (2) in the displacement direction and which is contacted by the sealing ring (4) against the free neck end (5), whereby the sealing ring is pressed together. By means of an indicator window (54) one can read off the fully closed position of the sealing cap with certainty. An interior pressure which is too high or a vacuum can be prevented by means of pressure and vacuum relief valves.
