The above bottle cap sealing structure, wherein: the bottle cap is provided with a safety ring, the safety ring is placed between the safety ring I and the safety ring II, the safety ring is wedge-shaped, and the minimum diameter of the end is slightly larger than the maximum diameter of the bottle mouth thread. Diameter, less than the maximum diameter of the safety ring retaining ring I; its front end inside maximum diameter is slightly greater than the safety ring retaining ring I diameter; its front end outside maximum diameter is less than the maximum diameter of the safety retaining ring II. The bottle cap and the safety ring are connected by a connecting body.

The sealing structure of the bottle cap above, wherein: the connecting small bodies are evenly arranged and the number is 2-10.

The sealing structure of the bottle cap above, wherein: the outer wall of the bottle cap is provided with vertical lines.

Compared with the prior art, the utility model has obvious advantages and beneficial effects. It can be seen from the above technical scheme that the inner end surface of the bottle cap is provided with an annular groove, and the sealing ring II is installed in the annular groove, and pressed on the top of the bottle mouth, so as to realize the sealing of the drink in the bottle. There is a bottle cap shoulder on the side wall inside the bottle cap, and a bottle mouth shoulder on the side wall of the bottle mouth. The sealing ring I is installed between the bottle cap shoulder and the bottle mouth shoulder, which can realize the sealing between the sealing ring I and the sealing ring II. The bottle mouth area closed between the two is the area in contact with the mouth when drinking, which fully guarantees the drinking hygiene. The bottle cap is provided with a safety ring, and the bottle cap and the safety ring are connected by a small connecting body, which not only realizes the integral sealing of the bottle cap and the bottle mouth, but also facilitates the opening of the bottle cap. The outer wall of the bottle cap is provided with vertical lines, which is more convenient for screwing when opening the cap.

detailed description:

Below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, features and effects of the bottle cap sealing structure proposed according to the present invention will be described in detail as follows.

Embodiment one

Referring to Fig. 1 and Fig. 3, the bottle cap sealing structure of the present invention includes a bottle cap 1 and a bottle mouth 2, wherein: the inner end surface of the bottle cap 1 is provided with an annular groove 12, and the sealing ring II13 is installed in the annular groove 12 inside, and pressed on the top of the bottle mouth 2; bottle cap shoulder 11 is provided on the inner side wall of the bottle cap 1, bottle mouth shoulder 9 is provided on the side wall of the bottle mouth 2, and the sealing ring I10 is installed on the bottle cap shoulder 11 and Between the shoulders 9 of the neck of the bottle. The bottle cap 1 and the bottle mouth 2 are provided with a bottle cap thread 8 and a bottle mouth thread 7 that cooperate with each other, and are located between the sealing ring I10 and the sealing ring II13. Preferably, the sealing ring I10 is a wedge-shaped sealing ring, and the bottle mouth area closed between the sealing ring I10 and the sealing ring II13 is the area in contact with the mouth when drinking, which fully ensures drinking hygiene.
