Abstract
A cap with valve includes a cap body 1, a flange portion 5, and a gasket 11. The cap body 1 has an external threaded portion 2 for threadedly engaging a fuel supply inlet. The flange portion 5 extends outwardly in the radial direction from an upper portion of the cap body 1. The annular gasket 11 has a substantially circular cross-section, and is disposed on a sealing surface of the flange portion 5. This gasket 11 has a projecting portion 15A in contact with flange portion 5 and this projecting portion extends along the entire circumference of the toroidal gasket 11. The projecting portion 15 A absorbs surface irregularities on flange portion 5 thus eliminating the need for additional manufacturing steps, such as grinding, thereby reducing the manufacturing cost of the cap with valve.
