A fuel tank for a motor vehicle has a connecting portion extending around an opening in the tank wall which is closed by a, holding cover, with the interposition of a sealing ring. The connection between the connecting portion and the holding cover is made by a fixing means urging the holding cover towards the connecting portion. The sealing ring is disposed in a groove in the connecting portion or the holding cover and the cross-sections of the groove and the sealing ring are so selected that, in its operative position of closing the opening the holding cover is supported directly by the end surface of the connecting portion, bearing against that end surface.

Why it's free to use
- Filed July 3, 1997 and granted March 5, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 3, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 3, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
