CA 2278000

A cap (12) is provided for a filler neck (14) having an open mouth (22) and two internal mounting flanges (38, 40) adjacent to the open mouth (22). Cap (12) comprises a handle (18), a body (16) coupled to handle (18) for rotation therewith, an annular seal (34) around body (16), first and second external position-locator lugs (78, 80) appended to body (16) and arranged to lie in spaced-apart relation to annular seal (34), and first and second spiral-shaped cap mounting members (86, 88) appended to body (16) to lie in a position between annular seal (34) and first and second external position-locator lugs (78, 80). The spiral-shaped cap mounting members (86, 88) are adapted to engage against the internal mounting flanges (38, 40) of the filler neck upon installation of body (16) in filler neck (14) to retain cap (12) in filler neck (14) and annular seal (34) in compression to establish a liquid fuel and vapor seal between cap (12) and filler neck (14).

Cette invention se rapporte à un bouchon (12) pour goulot de remplissage (14) ayant un passage ouvert (22) et deux brides de montage (38, 40) internes, adjacentes audit passage ouvert (22). Ledit bouchon (22) comporte un organe de préhension (18), un corps (16) couplé audit organe de préhension (18) de façon à tourner en même temps, un joint d'étanchéité annulaire (34) disposé autour du corps (16), un premier et un second tenons (78, 80) externes de détermination de la position, annexés au corps (16) et conçus pour se trouver à distance du joint annulaire (34), et un premier et un second éléments spiralés (86, 88) de montage du bouchon, annexés au corps (16) de manière à se trouver entre le joint annulaire (34) et les premier et second tenons (78, 80) externes de détermination de la position. Les éléments spiralés de montage du bouchon (86, 88) sont conçus pour s'appuyer contre les brides de montage internes (38, 40) du goulot de remplissage lors de l'installation du corps (16) dans le goulot de remplissage (14) de manière à bloquer le bouchon (12) dans le goulot de remplissage (14) et à maintenir le joint d'étanchéité (34) en compression, ce qui assure la formation d'un joint étanche au carburant liquide et à la vapeur, entre le bouchon (12) et le goulot de remplissage (14).
