The invention relates to a closure cap (10) for the filler neck (11) of a reservoir (12), in particular, one for fuel or motor oil for e.g. motor vehicles, comprising a grip (14) and a rotating lifting device (13) whose first part (sealing part 15) facing the grip (14) is provided with a sealing ring (16) and whose other part (tightening part 18), which faces away from the grip (14) and which is provided with detent lugs (44) serving to engage under a closure cap (62) of the filler neck (11), can be turned relative to the filler neck (11) when the closure cap (10) undergoes a turning motion. Said other part (tightening part 18) can, when the grip (14) undergoes a turning motion, be axially displaced relative to the first part (sealing part 15) of the rotating lifting device (13) against the force of a spring (19). This axial displacement is such that, in the closed position of the closure cap (10) on the filler neck (11) of the sealing ring (16) provided on the first part (sealing part 15), the tightening part is pressed against a sealing surface (63) of the filler neck (11), and during the movement of the grip (14), an axial play exists between the sealing surfaces of the sealing ring (16) and filler neck (11), whereby the first part (sealing part 15), with the axially acting sealing ring (16) remains, when the closure cap (10) undergoes a turning motion relative to the filler neck (11), unturnable with the filler neck (11) by means of a turning closing connection (31, 65). |
