Abstract

Dans cette structure d'étanchéité pour un capuchon, un corps d'étanchéité (7) qui comprend une section d'étanchéité (71) insérée dans un bec verseur (25) d'un corps principal de capuchon (2) et une section d'ajustement circonférentiel externe (72) présentant une section longitudinale en forme de U est fixé à un couvercle supérieur (3) par ajustement lâche de la section d'ajustement circonférentiel externe (72) à une section de cylindre d'ajustement (32) s'étendant vers le bas dans une forme cylindrique à partir de la surface supérieure (31) du couvercle supérieur (3). De plus, le corps principal de capuchon (2) comprend un cadre de bord (24) faisant saillie vers l'extérieur à partir de l'extrémité de base du bec verseur surélevé cylindrique (25), et lorsque la section d'étanchéité (71) est insérée dans le bec verseur (25), le bord inférieur de la section d'ajustement circonférentiel externe (72) est amené à venir en prise avec une section de mise de prise étagée (24a) formée sur le bord circonférentiel externe de la structure de bord (24). Grâce à cette configuration, il est possible d'assurer une performance d'étanchéité avant l'ouverture d'un joint et de maintenir la même performance d'étanchéité après l'ouverture du joint.
