Description

Technical Field

[0001] The utility model particularly relates to a sealing cover and a packaging bottle with strong sealing performance. Background Art

[0002] As a carrier, the primary function of a bottle cap is sealing. This is crucial for ensuring the proper storage of the contents and preventing the intrusion of foreign matter, bacteria, and gas leakage. For example, beer bottles contain large amounts of carbon dioxide. To safely contain this carbon dioxide within the beer, a highly airtight cap is required. Most existing bottle caps are crown-shaped, with 21 serrations along the outer circumference and a sealing gasket placed inside to prevent the carbon dioxide from leaking out. During use, the cap is pried open with a bottle opener, but this can significantly deform. When the cap is resealed to seal the remaining beer, the gas inside the bottle can escape. Alternatively, some sealing caps are threaded onto the beer bottle, but gaps can easily form at the threaded connection, ultimately leading to gas leaks. Utility Model Content

[0003] The utility model is intended to solve at least one of the technical problems in the prior art. To this end, the utility model proposes a sealing cap and a packaging bottle with strong sealing performance.

[0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions:

[0025] A sealing cover, referring to Figure 1-Figure 5 , including an elastic cover body 1, an inner plug portion 2 is provided on the elastic cover body 1, a sealing portion 3 is formed on the peripheral side of the elastic cover body 1, the sealing portion 3 and the inner plug portion 2 surround a mounting cavity for accommodating a container opening 20, and a handle portion 4 is provided on the elastic cover body 1. When the elastic cover body 1 is assembled on the container, the inner plug portion 2 extends into the container opening 20 while the sealing portion 3 hugs the edge of the opening 20 to seal the inside of the container.

[0026] Furthermore, the inner plug portion 2 is formed by recessing the elastic cover body 1 inwardly and integrally forming the elastic cover body 1 .

[0027] Furthermore, the handle portion 4 is provided with anti-slip grooves.

[0028] Furthermore, the elastic cover 1 is made of silicone material.

[0029] Furthermore, the sealing portion 3 is formed by bending from the edge of the elastic cover 1 toward the installation cavity.

[0030] A packaging bottle with strong sealing performance comprises a bottle body 5 and the above-mentioned sealing cover connected to the bottle body 5.

[0031] Furthermore, a stopper 6 is arranged around the opening 20, and a connecting portion 7 is provided in the installation cavity. The connecting portion 7 is arranged around the circumference of the inner plug 2. When the inner plug 2 extends into the opening 20, the connecting portion 7 is pressed against the stopper 6.

[0032] The working principle of this utility model is:

[0033] As Example 1, the container of the present application takes a beer bottle as an example. A accommodating cavity 1-1 for accommodating beer (i.e., the interior of the container) is defined in the bottle body 5. For example, a stopper 6 is provided in the opening 20 of the bottle body 5. Since the elastic cover 1 has a certain elasticity, it can be pressed against the sealing portion 3 during installation, and the sealing portion 3 is deformed. Finally, the sealing portion 3 will hug the edge of the opening 20. Since the inner plug 2 is connected to the elastic cover 1, it will also drive the inner plug 2 to move. Finally, the inner plug 2 extends into the opening 20. After the sealing cover is assembled, it can be opened from Figure 3-4 As can be seen in the figure, the elastic cover 1, the sealing portion 3 and the inner plug 2 are collectively arranged to form an installation cavity, which is used to accommodate the opening 20 of the bottle body 5. In the present application, a stopper 6 is arranged around the opening 20, and a connecting portion 7 is arranged in the installation cavity. The connecting portion 7 is arranged around the circumference of the inner plug 2, so when the inner plug 2 extends into the opening 20, the connecting portion 7 is pressed against the stopper 6. When it is necessary to open the beer bottle, one hand pulls the handle 4, and the other hand holds the bottle body 5, and lifts the handle 4 upward. Since the handle 4 is arranged on the elastic cover 1, when the handle 4 is lifted upward, the elastic cover 1 will also move upward, so the sealing cover can be removed from the opening 20. In actual use, even if the sealing cover needs to be re-sealed to seal the remaining beer in the bottle body 5, the sealing cover has a certain elasticity, so the sealing cover can still seal the bottle body 5 to prevent gas from escaping. In order to better facilitate the use of the user, the present application provides anti-slip grooves on the handle portion 4 to prevent the user from slipping when using it.

[0034] In the technology of the present application, when the sealing cover is assembled on the bottle body 5, Figure 3 It can be seen that the sealing portion 3 holds the edge of the opening 20. Since the sealing portion 3 itself has a certain elasticity, the sealing portion 3 can adapt to the shape of the bottle body 5 and fit tightly against the edge of the opening 20 to achieve a first layer of sealing. The present application also provides a stopper 6 in the opening 20, and a connecting portion 7 is provided on the elastic cover 1. When the connecting portion 7 abuts against the stopper, a second layer of sealing is achieved. The present application also provides an inner plug 2 on the elastic cover 1. The inner plug 2 extends into the opening 20 to achieve a third layer of sealing at the opening 20. After multiple layers of sealing, the sealing cover of the present application can keep the accommodating cavity of the bottle body 5 in a sealed state, effectively preventing gas from escaping and ensuring the taste of the beer. In the above technology, the sealing cover can be made of silicone.

[0035] Example 1 of the present application only uses beer bottles as an example, which does not mean that only beer bottles are applicable to the design concept of the present application. As long as the packaging container has sealing requirements and does not produce chemical reactions with the sealing cover, such as sparkling water, it will be applicable.

[0036] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to illustrate rather than limit the present invention, which shall be defined by the claims.
