Description

Technical Field

[0001] This utility model belongs to the field of bottle cap technology, specifically relating to a novel screw-on beer bottle cap that can be easily opened by applying force. Background Technology

[0002] In existing high-end beer packaging, the original easy-pull structure has been changed to a screw-on cap. When using this type of cap, it is usually molded in one piece and then screwed onto the bottle mouth. The screwing machine forms threads by pressing the threads on the bottle mouth into the threaded area, and then permanently fixes it to the bottle. When the beer is opened, the cap is opened by twisting off the connection point of the dividing area.

[0003] The current technical problem is that, in this type of bottle cap structure, the internal sealing structure is directly fitted inside the cap. After mechanical tightening and sealing, the sealing structure is strongly pressed against the top edge of the bottle mouth. However, when opening the bottle, the person opening it must use considerable force to overcome the axial friction between the sealing structure and the top of the bottle mouth. Typically, women with less physical strength cannot open the bottle independently.

[0004] Given the current situation of this type of bottle cap, as the research and development unit of the relevant product, it is very necessary for the applicant to improve the existing bottle cap structure and design a bottle cap that is easy to open and requires less effort to open, so as to overcome the drawbacks of the existing technology. Summary of the Invention

[0005] To overcome the shortcomings of existing technology, this utility model provides a novel screw-on beer bottle cap with a novel structural design and an internal sliding pad design, which can achieve sealing while ensuring axial compression.

[0006] To achieve the above technical objectives, the present invention adopts the following solution:

[0007] A novel screw-on beer bottle cap includes a cap body with a threaded forming area on the side wall of the cap body. A separation upper section and a separation lower section are provided below the threaded forming area. The separation upper section and the separation lower section are connected by several connection points. The top of the inside of the cap body is smooth. A sliding pad and a sealing pad are provided from top to bottom inside the cap body. The bottom surface of the sealing pad is provided with a compression protrusion for compression contact with the upper end of the bottle mouth.

[0008] The outer periphery of the cover is provided with a compression locking area, which, after being compressed and deformed, constrains the sealing gasket inside the cover.

[0009] An oxygen-dissolving coating is provided between the sliding pad and the sealing pad or between the sliding pad and the bottle cap. The oxygen-dissolving coating is used to absorb or decompose oxygen in the beer to improve the taste of the beer.

[0010] The sliding pad has a smooth surface on one side that contacts the bottle cap, while the other side has a frosted surface. The frosted surface increases the friction between the sliding pad and the sealing gasket, ensuring that the sliding pad rotates synchronously with the sealing gasket.

[0011] The beneficial effects of this utility model are as follows: This utility model features a smooth top surface inside the cap, and a sliding pad and a sealing pad are arranged from top to bottom inside the cap. The sealing pad has a compression protrusion for compression contact with the top of the bottle mouth. When opening the beer bottle cap, the sealing pad and the bottle mouth are compressed together and can rotate relative to the bottle cap on the sliding pad. There is no large friction between the sealing pad and the bottle cap, and the user can easily unscrew the bottle cap. This utility model also has an oxygen-dissolving coating in the sealing pad area, which can dissolve oxygen to improve the taste of beer. It overcomes the shortcomings of the prior art and is an ideal way to unscrew beer bottle caps. Attached Figure Description

[0018] As shown in the attached drawings, this utility model discloses a novel screw-on beer bottle cap, comprising a cap body 1. A threaded forming area 3 is provided on the side wall of the cap body 1. A separating upper section 4 and a separating lower section 5 are provided at the lower part of the threaded forming area 3. The separating upper section 3 and the separating lower section 5 are connected by several connection points 6. The key design feature of this utility model is that the top of the inner surface of the cap body 1 is smoothly finished. Figure 2 , 3As shown, a sliding pad 7 and a sealing pad 9 are arranged from top to bottom inside the cap 1. A compression protrusion 91 is provided below the sealing pad 9 for compression contact with the upper end of the bottle mouth. When the sliding pad 7 and the sealing pad 9 are assembled with the cap 1, a compression locking area 2 is provided around the periphery of the cap 1. After compression deformation, the compression locking area 2 constrains the compression edge 92 of the sealing pad 9 inside the cap 1, thereby constraining the sliding pad 7 and the sealing pad 9.

[0019] In the above assembly structure, such as Figure 4 As shown, the side of the sliding pad 7 that contacts the cover 1 is smooth, while the other side is provided with a frosted surface 71. The frosted surface 71 can increase the friction between the sliding pad 7 and the sealing gasket 9 by contacting the sealing gasket 9, without affecting the rotation of the sliding pad 7 under force within the cover 1.

[0020] Furthermore, an oxygen-dissolving coating 8 is provided between the sliding pad 7 and the sealing pad 9, or between the sliding pad 7 and the cap 1. The purpose of the oxygen-dissolving coating 8 is to absorb or decompose oxygen in the beer to improve its taste. As a further option, the oxygen-dissolving coating 8 can be made of tea polyphenols. Tea polyphenol molecules contain multiple phenolic hydroxyl groups (-OH), which have strong reducing properties and can react with oxygen to generate stable oxidation products. Through this reaction, tea polyphenols can consume free oxygen in the solution, thereby reducing the oxygen concentration. Furthermore, tea polyphenols can scavenge free radicals (such as superoxide anion free radicals, hydroxyl free radicals, etc.) in food or solution. These free radicals are initiators of oxidation reactions. By scavenging free radicals, tea polyphenols can block oxidation chain reactions, thereby delaying the oxidative deterioration of food. Through the above mechanism, tea polyphenols can protect easily oxidized components in beer (such as vitamins), extend the shelf life of beer, and maintain the color, flavor, and nutritional value of beer.

[0021] The dissolved oxygen coating 8 can also be made of vitamin C, because the enediol structure in the vitamin C molecule has strong reducing properties and is easily oxidized. It can react with oxygen in water and is used for deoxygenation in some biological experiments where the oxygen content of the water is critical. In this embodiment, it is preferred to place the dissolved oxygen coating 8 between the sliding pad 7 and the sealing pad 9.

[0022] In summary, when this new type of unscrewed beer bottle cap is used, the sealing gasket 9 and the bottle mouth are pressed together and can rotate relative to the cap body 1 on the sliding pad 7. There is no large friction between the sealing gasket 9 and the bottle cap, and the user can easily unscrew the cap.

[0023] This invention also features an oxygen-dissolving coating 8 in the sealing gasket area, which can dissolve oxygen to reduce the oxygen content in beer, ultimately improving the beer's taste. It overcomes the shortcomings of existing technologies and is an ideal screw-on beer bottle cap.
