During the process of tightening the bottle cap, the piston rod moves the bottom of the fixed cylinder, so that the gas can be squeezed into the annular groove, so that the gas in the annular groove squeezes the rubber skin to expand and fully fit with the inner wall of the wine bottle. At the same time, the expanded rubber skin can press the annular sheet inside the wine bottle, thereby realizing the sealing of the wine bottle mouth by inflation expansion, thereby improving the sealing effect of the wine bottle mouth.

The technical solution to achieve the purpose of the utility model is: an anti-overflow polymer wine bottle cap, including a cap body, an inner cap is provided inside the cap body, and a circular groove is provided on the outer cylindrical wall of the inner cap, and also includes;

A rubber skin, wherein the rubber skin is fixedly connected in the circular groove;

An inflation mechanism, wherein the inflation mechanism is located on the inner cover;

The inflation mechanism includes two fixing holes opened on the inner wall of the top of the annular groove, the two fixing holes are fixedly connected with fixing tubes, the tops of the two fixing tubes are fixedly connected with fixing cylinders, the tops of the two fixing cylinders are opened with sliding holes, the two sliding holes are slidably connected with piston rods, and the bottom ends of the two piston rods are slidably connected to the inner walls of the two fixing cylinders respectively.

In some embodiments, the top ends of the two piston rods are fixedly connected to the L-shaped rod, the bottom ends of the two L-shaped rods are commonly fixedly connected to a fixing ring, and the fixing ring is fixedly connected to the inner wall of the bottle cap body.

In some embodiments, a movable rod is fixedly connected to the top of the inner cover, a fixed rod is slidably sleeved on the top of the movable rod, and the top of the fixed rod is fixedly connected to the top inner wall of the bottle cap body.

In some embodiments, a compression spring is sleeved on the fixing rod, and two ends of the compression spring are fixedly connected to the bottle cap body and the inner cover respectively.

In some embodiments, a circular ring sheet is fixedly connected to the cylindrical outer side wall of the inner cover, and the circular ring sheet is located below the rubber skin.

In some embodiments, the annular sheet is made of rubber.

Compared with the prior art, the present invention has the following significant advantages:

The utility model provides an inflation mechanism. During the process of tightening the bottle cap, the fixed rod, the movable rod and the extrusion spring cooperate with each other to press the inner cover on the bottle mouth of the wine bottle. At the same time, the L-shaped rod drives the piston rod to move toward the bottom of the fixed cylinder, and then the gas can be squeezed into the annular groove, so that the gas in the annular groove squeezes the rubber skin to expand and fully fit with the inner wall of the wine bottle. At the same time, the expanded rubber skin can press the annular sheet inside the wine bottle, so that the bottle mouth of the wine bottle is sealed by inflation, thereby improving the sealing effect of the bottle mouth of the wine bottle.

The invention solves the existing problem that the surface of the inner cover is not flat enough, so that the inner cover cannot be fully fitted with the inner wall of the wine bottle.
