Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1 to 3 As shown, in one embodiment of this utility model, a bottle stopper 100 is provided. The bottle stopper 100 includes a stopper body 10 with an internal air passage 11, a cap 20 that cooperates with the air passage 11, and a sealing member 30 for opening and closing the air passage 11. The stopper body 10 is inserted into the opening of a bottle, and the air passage 11 is used to connect the outside world and the inner cavity of the bottle. The sealing member 30 includes a cut 31 and a plurality of compression portions 32 forming the cut 31. The plurality of compression portions 32 are mutually compressed to keep the cut 31 in a sealed state.

[0026] Furthermore, the cut 31 can be configured as a cross shape. Of course, in some embodiments, the cut 31 can also be configured as a star shape. Therefore, the shape of the cut 31 can be set as needed, as long as it facilitates the insertion of a needle and achieves a bottle seal.

[0027] The aforementioned bottle stopper 100, through the sealing element 30 and the cap 20, can achieve a double closure of the gas passage 11. Furthermore, when inflation is needed, simply inserting the inflation needle into the cut 31 allows for inflation into the bottle, making operation simple and convenient.

[0028] In this embodiment, the bottle stopper 100 can be made of rubber. A rubber bottle stopper 100 has excellent sealing properties, effectively preventing air and moisture from entering the bottle, thereby maintaining the quality of the wine inside. Furthermore, the rubber bottle stopper 100 is elastic, not easily deformed, and has a long service life. In addition, the rubber bottle stopper 100 also has anti-mildew and anti-odor properties, effectively protecting the wine inside the bottle from the influence of the external environment.

[0029] Furthermore, the bottle stopper 100 can be made as a single piece, which makes the bottle stopper 100 more robust and durable, and less prone to deformation or breakage. In addition, the single-piece design can also make the bottle stopper 100 more aesthetically pleasing, thereby increasing the perceived quality of the product.

[0030] like Figure 4 and Figure 5 As shown, the cap 20 also includes a cap body 21 inserted into the air passage 11 and a brim 22 extending from the cap body 21. This not only makes it convenient for the cap body 21 to cover the upper end 112 of the air passage 11 for easy use, but also increases the contact length between the cap 20 and the plug 10, reducing the probability of gas leakage between the cap 20 and the plug 10.

[0031] Furthermore, the cap brim 22 may be L-shaped. An insertion gap 23 is formed between the cap brim 22 and the cap body 21. The stopper 10 is provided with a protrusion 12 that mates with the insertion gap 23, thereby forming a labyrinthine passage at the contact point between the cap 20 and the stopper 10 to reduce the risk of gas leakage and improve the sealing effect of the stopper 100. Additionally, a raised edge may be provided on the outer periphery of the cap brim 22 to facilitate the user inserting the cap 20 into the stopper 10.

[0032] Furthermore, the boss 12 may be tapered, and the insertion gap 23 may be adapted to the boss 12 to increase the contact length between the cap 20 and the stopper 10, thereby increasing the length of the leakage path of gas between the cap 20 and the stopper 10, reducing the possibility of gas leakage, and thus improving the sealing performance of the stopper 100.

[0033] In this embodiment, the gas passage 11 has an upper end 112 and a lower end 113 disposed opposite to each other. The cap 20 can cover the upper end 112 of the gas passage 11, and the lower end 113 can be inserted into the bottle body. The sealing member 30 can be located inside the gas passage 11, and the distance from the sealing member 30 to the upper end 112 is approximately the same as the covering depth of the cap 20, so that when the cap 20 is covered by the stopper 10, the end of the cap 20 can abut against the sealing member 30 to ensure that the cut 31 can be completely closed.

[0034] like Figure 5 and Figure 6 As shown, the bottle stopper 100 also includes a sealing structure 40 connecting the cap 20 and the stopper body 10. The sealing structure 40 includes a retaining strip 41 and a limiting groove 42 that cooperates with the retaining strip 41, thereby improving the sealing strength between the cap 20 and the stopper body 10.

[0035] Furthermore, the retaining strip 41 is disposed in one of the cap body 21 and the inner wall 114 of the air passage, and the limiting groove 42 is disposed in the other of the cap body 21 and the inner wall 114 of the air passage. In this embodiment, the retaining strip 41 is disposed in the cap body 21, and the limiting groove 42 is disposed in the inner wall 114 of the air passage.

[0036] Furthermore, the bottle stopper 100 also includes a connecting structure 50 connecting the cap 20 and the stopper body 10 to prevent the cap 20 from being lost. The connecting structure 50 may be configured as a connecting strip 51.

[0037] like Figure 7 As shown, the plug 10 also includes a protruding ridge 13 on the outer periphery of the boss 12, so that the contact between the cover and the plug 10 is closer and tighter, improving the sealing effect between the cap 20 and the plug 10. Of course, in some embodiments, the cap 20 and the plug 10 can also be configured as a threaded connection. That is, the boss 12 can also be provided with an external thread, and the cap 20 is provided with an internal thread that mates with the external thread, so as to realize the threaded connection between the cap 20 and the plug 10.

[0038] In this embodiment, the outer periphery of the stopper 10 is further provided with a plurality of annular protrusions 14 to enhance the sealing strength between the stopper 10 and the bottle opening. Specifically, three annular protrusions 14 may be provided. From top to bottom, they are a first protrusion 141, a second protrusion 142, and a third protrusion 143. The first protrusion 141 and the second protrusion 142 are inclined upwards. The third protrusion 143 is set to be straight to ensure that the stopper 10 and the inner wall of the bottle can be completely sealed, thus ensuring the sealing performance of the bottle stopper 100.

[0039] Furthermore, the stopper 10 also includes an insertion portion 151 and a gripping portion 152, with the insertion portion 151 located at the lower end of the gripping portion 152. The insertion portion 151 is used to insert into the bottle opening, and the gripping portion 152 is used for gripping to install the stopper 100. The annular convex wing 14 is disposed on the insertion portion 151. The gripping portion 152 is tapered, meaning it has a larger diameter end and a smaller diameter end opposite to each other, with the larger diameter end located above the smaller diameter end. This facilitates gripping and use of the stopper 100, improving the comfort of using the stopper 100.

[0040] Furthermore, the outer diameter of the gripping part 152 is larger than the outer diameter of the insertion part 151. When the insertion part 151 is inserted into the bottle opening, the gripping part 152 can also abut against the outer edge of the bottle opening, thereby improving the sealing effect of the stopper 10.

[0041] In one embodiment of this utility model, a container bottle assembly is also provided, the container bottle assembly including a bottle body and the aforementioned bottle stopper 100, the bottle stopper 100 being inserted into the opening of the bottle body. The container bottle assembly can be used to hold wine.

[0042] In summary, the beneficial effects of this utility model are as follows: the bottle stopper 100 has an air passage 11 inside the stopper body 10, and the air passage 11 can be double-closed by the sealing element 30 and the cap 20. When inflation is needed, the inflation needle can be inserted into the cut 31 to inflate the bottle. The operation is simple and convenient.
