| 摘要 |
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) that is provided with a sealing ring (16) and 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. A tightening part (18) can, when the grip (14) undergoes a turning motion, be axially displaced relative to a 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), the sealing ring (16) provided on the sealing part (15) is pressed against a sealing surface (63) of the filler neck (11). The sealing part (15), along with the axially acting sealing ring (16), remains unturnable relative to the filler neck (11) by means of a turning closing connection (31, 65) therewith when the closure cap (10) undergoes a turning motion. |
