The present invention relates to a bottle cap with leakage-proof feature for liquid therein, which comprises a bottle cap and a dividing disk, wherein bottle cap having an internal hollow cavity, an internal communicating channel and an internal concentric lining ring with inwards buckling groove ring being crotched in the inner wall of the hollow cavity facing the communicating channel such that a flexible rift ring being formed between the peripheral surface of the lining ring and the inner surface of the communicating channel; And the dividing disk having an up-facing flexible cleft ring being notched near the peripheral of the top surface. By means mutual counter elastic stress by the strained flexible rift ring and flexible cleft ring reciprocally, the buckling-fitting condition between the lateral surface of the dividing disk and the inner surface of the lining ring is more firmly tight.

La présente invention porte sur une capsule de bouteille avec une caractéristique anti-fuite pour un liquide dans celle-ci, qui comprend une capsule de bouteille et un disque de division, la capsule de bouteille ayant une cavité creuse interne, un canal de communication interne et un anneau de revêtement concentrique interne avec un anneau à rainure se déformant vers l'intérieur qui est adapté dans la paroi interne de la cavité creuse opposée au canal de communication, de telle sorte qu'un anneau de rupture flexible est formé entre la surface périphérique de l'anneau de revêtement et la surface interne du canal de communication ; et le disque de division ayant un anneau fendu flexible tourné vers le haut, qui est entaillé à proximité de la périphérie de la surface supérieure. Au moyen d'une contrainte élastique inverse mutuelle par l'anneau de rupture flexible et l'anneau fendu flexible sous contrainte, la condition d'ajustement par déformation entre la surface latérale du disque de division et la surface interne de l'anneau de revêtement est plus fermement serrée.
