DETAILED DESCRIPTION

[0037] Reference Figure 1 A bidirectional wine bottle cap structure for closing and connecting two bottle bodies 7, specifically including an inner plug 1, an inner sleeve 2, an inner cover 6, a liner cover 3, a first outer sleeve 4 and a second outer sleeve 5. Those skilled in the art should understand that the bottle cap structure in the present application is only used as an example of wine packaging, and the bottle cap structure provided by the present application is of course also applicable to the bottle caps of other beverage bottles (including liquid beverages and some powder beverages).

[0038] Reference Figure 2 The inner plug 1 is funnel-shaped and has two, one of which is embedded in the bottle mouth of one of the bottle bodies 7, and the other is embedded in the bottle mouth of the other bottle body 7. Specifically, the inner plug 1 is in interference fit with the bottle mouth to form a seal. The diameter of the inner plug 1 gradually decreases (both the inner diameter and the outer diameter decrease) in the direction from the bottle mouth to the bottle bottom of the bottle body 7 along which the inner plug 1 is located. The side wall of the inner plug 1 is provided with two height-different through holes, one for wine flow and the other for ventilation, and each through hole is separated by a septum 103 to avoid interference between wine flow and ventilation. Further, in this embodiment, the small-diameter end of the inner plug 1 is in a pointed structure, which facilitates the gathering of wine in the center. It should be noted that the "pointed structure" can be understood as the small-diameter end gathering into a point, or as the small-diameter end gathering into a smaller-diameter circle.

[0039] After the bottle cap is assembled with the bottle body 7, a closed channel is formed between the two bottle bodies 7. Due to the two height-different through holes of the inner plug 1, under the gravity of the wine, the wine in the upper end bottle body 7 will flow slowly downward through the lower position through hole of the upper end inner plug 1, and then flow slowly into the lower end bottle body 7 through the lower position through hole of the lower end inner plug 1, forming a sandglass type dripping phenomenon, increasing the interestingness and observability, and meeting the market demand. Moreover, the upper position through hole of the upper end inner plug 1 and the upper position through hole of the lower end inner plug 1 are used for gas flow, balancing the pressure in the two bottle bodies 7, and meanwhile, each through hole is separated by the partition piece 103, so that the wine downward dripping and the bubble upward floating do not interfere with each other, ensuring that the wine downward flow can be smoothly carried out.

[0040] For the convenience of understanding, the holes used for wine flow in the two through holes are defined as wine flow holes 101, and the holes used for air exchange are defined as air exchange holes 102. As shown in the figure, the positions of the wine flow holes 101 and the air exchange holes 102 are as follows. Figure 1 Figure 1 It should be understood that when the two bottle bodies 7 exchange directions (i.e. are inverted by rotating 180°), due to the exchange of the heights of the two through holes in the same inner plug 1, the wine flow hole 101 in the figure will serve as the air exchange hole 102, and the air exchange hole 102 in the figure will serve as the wine flow hole 101.

[0041] In addition, it should be understood that in other embodiments of the present application, a plurality of through holes can be provided, a part of the through holes are provided at the same height, and another part of the through holes are provided at another same height. On this basis, the above-mentioned "each through hole is separated by the partition piece 103" can be understood as that a part of the through holes used for wine flow are separated from a part of the through holes used for air exchange, or can be understood as that each through hole is separated.

[0042] One end of the inner sleeve 2 is provided with external threads, and the other end of the inner sleeve 2 is fixedly sleeved on the outer wall of one of the bottle mouths, that is, the inner sleeve 2 is relatively fixed with the bottle mouth. The end of the inner sleeve 2 provided with external threads is defined as the lower end, and the other end is defined as the upper end. It is easy to understand that all the descriptions about "upper" and "lower" directions in the present application are based on this. In actual application, if the two bottle bodies 7 exchange the upper and lower positions, the upper and lower described in the text should be exchanged. The inner plug 1 at the upper end of the bottle mouth of the inner sleeve 2 is sealingly connected, specifically, the lower end of the upper end inner plug 1 is in interference fit with the inner sleeve 2, forming a seal.

[0043] The upper end of the inner cover 6 is provided with internal threads matched with the external threads, and the inner cover 6 is internally provided with a sealing ring. The sealing ring is sealingly connected between the inner sleeve 2, specifically, the sealing ring is in interference fit with the inner sleeve 2, forming a seal. The lower end of the inner cover 6 is sealingly connected with the lower end inner plug 1, specifically, the lower end of the inner cover 6 is in interference fit with the upper end of the lower end inner plug 1, forming a seal. It is worth mentioning that the sealing manner in the present application includes but is not limited to straight type smooth surface fit sealing, ring type rib and ring groove fit sealing.​

[0044] The upper end of the lining cover 3 is fixedly sleeved on the outer wall of the inner cover 6, that is, the lining cover 3 is relatively fixed with the inner cover 6. The first outer sleeve 4 is fixedly sleeved on the upper end outer wall of the inner sleeve 2, that is, the first outer sleeve 4 is relatively fixed with the inner sleeve 2. The upper end outer wall of the second outer sleeve 5 is fixedly connected with the lower end inner wall of the lining cover 3, that is, the second outer sleeve 5 is relatively fixed with the lining cover 3. The lower end of the second outer sleeve 5 is fixedly sleeved on the outer wall of the lower end bottle mouth, that is, the second outer sleeve 5 is relatively fixed with the lower end bottle body 7.

[0045] On the basis of the above, it can be understood that after the bottle cap is assembled with the bottle body 7, the first outer sleeve 4, the inner sleeve 2, the upper end inner plug 1 and the upper end bottle body 7 form an integral whole (defined as a first integral whole for the convenience of description), and the second outer sleeve 5, the lining cover 3, the inner cover 6, the lower end inner plug 1 and the lower end bottle body 7 form an integral whole (defined as a second integral whole for the convenience of description). Since the inner cover 6 is connected with the inner sleeve 2 through threads, by rotating the lining cover 3, the first integral whole and the second integral whole can be separated from each other, so that the bottle cap is opened. After the bottle cap is opened, the two bottle bodies 7 can both pour out the wine.

[0046] With reference to Figure 5 and Figure 7 , the first outer sleeve 4 and the lining cover 3 are provided with an anti-fake structure. As an option, the anti-fake structure in the embodiment is specifically as follows. The lower end of the first outer sleeve 4 is provided with an anti-fake tooth 401, and the upper end of the lining cover 3 is provided with a containing groove 301 for containing the anti-fake tooth 401. When the bottle cap is opened, the rotation of the lining cover 3 will break the anti-fake tooth, so that the anti-fake function is realized. In other embodiments, of course, other anti-fake structures can also be used, for example, a warning ring anti-fake structure, and the warning ring is marked with anti-fake words such as “opened”, and the warning ring leaks out after the bottle cap is opened.

[0047] With reference to Figure 1 , Figure 7 , Figure 8 , Figure 3 and Figure 4 , as an option, the relative fixing mode between the first outer sleeve 4 and the inner sleeve 2 adopts an axial limiting + circumferential limiting mode.

The inner wall of the first outer sleeve 4 is provided with a plurality of first anti-rotation teeth 404 in the circumferential direction, and the upper end outer wall of the inner sleeve 2 is provided with a plurality of second anti-rotation teeth 202 matched with the first anti-rotation teeth 404, so as to avoid the relative rotation of the first outer sleeve 4 and the inner sleeve 2, and realize the circumferential limiting.
