Abstract

La présente invention concerne un couvercle étanche à l'air permettant de couvrir le bord d'ouverture (11, 11A, 11B, 11C, 11D) d'un récipient (10, 10A, 10B, 10C, 10D), le couvercle étanche à l'air comprenant une pièce souple étanche à l'air (20) ainsi qu'un couvercle supérieur dur (30). La pièce souple étanche à l'air (20) est placée de manière fixe au-dessous du couvercle supérieur dur (30). La pièce souple étanche à l'air (20) est dotée d'un bord d'étanchéité (21) en contact avec le bord d'ouverture (11, 11A, 11B, 11C, 11D), d'une partie centrale (22) et d'une partie périphérique (23) respectivement à l'intérieur et à l'extérieur du bord d'étanchéité (21) avec un espace (D) entre le bord d'étanchéité (21) et le couvercle supérieur dur (30). Lorsque la partie centrale de la pièce souple étanche à l'air se déplace vers le bas et que la partie périphérique de la pièce souple étanche à l'air s'élève sous la contrainte, le couvercle supérieur dur peut forcer la partie périphérique à s'incurver vers le bas, ce qui permet d'augmenter la zone de contact entre le bord d'étanchéité et le bord d'ouverture de manière à assurer une bonne étanchéité du récipient.
