[0002] Existing bottle caps such as figure 1 Among them, the inner plug and upper inner cover are made of soft plastic such as PE. In the whole product, such as bottled wine or bottled beverages, after a long period of storage, the plastic of the inner plug is likely to harden and shrink, resulting in the leakage of wine
In the existing bottle cap, during the pouring process, the air enters the bottle body unevenly, so that the wine liquid fluctuates during the pouring process, which is easy to cause waste

Embodiment Construction

[0021] Such as figure 2 , 3 Among them, a leak-proof bottle cap includes a lower cap 5 fixed on the bottle mouth of the bottle body 6. In this example, the lower cap 5 is hooked on the bottle by a plurality of limit barbs 7 located in the lower cap 5. The step at the lower end of the outer wall of the mouth, so that the lower cover 5 cannot be disassembled after being installed, and it is not easy to rotate.

[0022] There is also an inner plug 4 located in the bottle mouth, and a through hole is provided in the inner plug 4. The extension 31 at the bottom of the bottle mouth 3 extends into the inner plug 4, and is interference fit with the inner plug 4. Preferably, the The outer wall of the inner plug 4 is provided with a plurality of sealing rings, and the depth of the extending portion 31 protruding into the inner plug 4 is at least greater than the depth of the inner plug 4 provided with the sealing rings. To ensure that the inner plug 4 is pressed against the inner wal...

Abstract

A leak-proof bottle cap comprises a lower cap fixed at a bottle opening of a bottle body and an inner plug arranged in the bottle opening. A through hole is formed in the inner plug. An extending portion of the lower portion of a bottle neck extends into the inner plug. A step portion is formed in the middle of the bottle neck, and a connecting portion is arranged on the upper portion of the bottle neck. An outer thread is formed on the outer wall of the connecting portion. A wine through is formed in the bottle neck. An upper inner cap is connected with the connecting portion through an inner thread and fixedly connected with an upper cap through a fastener. The bottle neck with the extending portion extending into the through hole of the inner plug is adopted and made of hard plastic so as to support the inner plug. According to the arrangement, after long-term storage, the inner plug and the bottle neck are free of deformation, thus excellent sealing effect between the bottle plug and the bottle body is guaranteed to avoid leakage of wine.

Description

technical field [0001] The invention relates to the field of bottle caps for containers containing liquids, in particular to a leak-proof bottle cap. Background technique [0002] Existing bottle caps such as figure 1 Among them, the inner plug and upper inner cover are made of soft plastic such as PE. In the whole product, such as bottled wine or bottled beverages, after a long period of storage, the plastic of the inner plug is likely to harden and shrink, resulting in leakage of wine. In the existing bottle cap, during the pouring process, the air enters the bottle body unevenly, so that the wine liquid fluctuates during the pouring process, which is easy to cause waste. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a leak-proof bottle cap, which can ensure a more reliable seal between the inner plug and the bottle mouth. In a further improved solution, the fluctuation of liquid, such as wine, during pouri...
