DETAILED DESCRIPTION

[0037] refer to Figure 1 A two-way flow wine bottle cap structure is used to close and connect the upper and lower bottle bodies 7, specifically including an inner plug 1, an inner sleeve 2, an inner cover 6, a liner cover 3, a first outer cover 4 and a second outer cover 5. Those skilled in the art should understand that the present invention only takes the packaging of liquid wine as an example to introduce the bottle cap structure, and the bottle cap structure provided by the present invention is of course also applicable to the bottle caps of other beverage bottles (including liquid beverages and some powdered beverages).

[0038] refer to Figure 2 The inner plug 1 is funnel-shaped and is provided with two, one inner plug 1 is embedded in the bottle mouth of one of the bottle bodies 7, and the other inner plug 1 is embedded in the bottle mouth of the other bottle body 7. Specifically, the inner plug 1 and the bottle mouth adopt an interference fit to form a seal. The diameter of the inner plug 1 gradually decreases in the direction from the bottle mouth of the bottle body 7 where the inner plug 1 is located to the bottom of the bottle (both the inner diameter and the outer diameter decrease). The side wall of the inner plug 1 is provided with two through holes of different heights, one for wine flow and the other for ventilation. The through holes are separated by a spacer 103 to avoid interference between wine flow and ventilation. Furthermore, in this embodiment, the small diameter end of the inner plug 1 is a pointed structure, which is convenient for the wine to gather and center. It is worth noting that the "pointed structure" can be understood as the small diameter end gathering into a point, and can also be understood as the small diameter end gathering into a circle with a smaller diameter.

[0039] After the bottle cap and the bottle body 7 are assembled, a closed passage is formed between the two bottle bodies 7. Since the inner plug 1 is provided with two through holes at different heights, under the action of the gravity of the wine, the wine in the upper bottle body 7 will slowly flow downward through the through hole at the lower position on the upper inner plug 1, and then slowly flow into the lower bottle body 7 through the through hole at the lower position on the lower inner plug 1, forming an hourglass-like dripping phenomenon, which increases the fun and ornamental value and meets the market demand; and the through hole at the higher position of the upper inner plug 1 and the through hole at the higher position of the lower inner end are used for gas flow to balance the pressure in the two bottle bodies 7. At the same time, the through holes are separated by the spacer 103, so that the wine dripping downward and the bubbles floating evenly do not interfere with each other, ensuring that the wine can flow downward smoothly.

[0040] For ease of understanding, the hole for wine flow in the two through holes is defined as the wine flow hole 101, and the hole for ventilation is defined as the ventilation hole 102. The positions of the wine flow hole 101 and the ventilation hole 102 are as follows: Figure 1 It should be understood that when Figure 1 When the two bottle bodies 7 exchange directions (i.e. rotate 180° and invert), since the heights of the two through holes in the same inner plug 1 are exchanged, the wine flow hole 101 in the figure will serve as the ventilation hole 102, and the ventilation 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 invention, multiple through holes may be provided, with some through holes being provided at the same height and other through holes being provided at another same height. On this basis, the above-mentioned "the through holes are separated by spacers 103" can be understood as a part of the through holes used for wine flow being separated from a part of the through holes used for ventilation, or can be understood as each through hole being separated.

[0042] One end of the inner sleeve 2 is provided with an external thread, 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 to the bottle mouth. The end of the inner sleeve 2 provided with the external thread is defined as the lower end, and the other end is defined as the upper end. It is easy to understand that all descriptions of the "upper" and "lower" directions in the present invention are based on this. In practical applications, 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 sealed and connected. Specifically, the lower end of the upper inner plug 1 is interference fit with the inner sleeve 2 to form a seal.

[0043] The upper end of the inner cover 6 is provided with an inner thread that matches the outer thread, and a sealing ring is provided inside the upper end, and the sealing ring is sealed to the inner sleeve 2. Specifically, the sealing ring and the inner sleeve 2 are interference fit to form a seal. The lower end of the inner cover 6 is sealed to the lower end inner plug 1. Specifically, the lower end of the inner cover 6 is interference fit with the upper end of the lower end inner plug 1 to form a seal. It is worth noting that the sealing method in the present invention includes but is not limited to the sealing formed by the straight smooth surface matching and the travel sealing formed by the annular rib and the annular groove matching.

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

[0045] Based on the above, it can be understood that after the bottle cap and the bottle body 7 are assembled, the first outer sleeve 4, the inner sleeve 2, the upper inner plug 1 and the upper bottle body 7 are an integral body (for the convenience of description, defined as the first integral body), and the second outer sleeve 5, the liner 3, the inner cover 6 and the lower inner plug 1 and the lower bottle body 7 are an integral body (for the convenience of description, defined as the second integral body). Since the inner cover 6 and the inner sleeve 2 are connected by threads, the first integral body and the second integral body can be separated from each other by rotating the liner 3, and the bottle cap can be opened. After the bottle cap is opened, the wine can be poured out of the two bottle bodies 7.

[0046] refer to Figure 5 and Figure 7 , an anti-counterfeiting structure is provided between the first outer cover 4 and the lining cover 3. As an option, the anti-counterfeiting structure in this embodiment is as follows: the lower end of the first outer cover 4 is provided with an anti-counterfeiting tooth 401, and the upper end of the lining cover 3 is provided with a receiving groove 301 for accommodating the anti-counterfeiting tooth 401. When the bottle cap is opened, the rotation of the lining cover 3 will break the anti-rotation tooth to achieve anti-counterfeiting. In other embodiments, of course, other anti-counterfeiting structures can also be used, such as warning ring anti-counterfeiting, with anti-counterfeiting words such as "opened" marked on the warning ring, and the warning ring leaks out after the bottle cap is opened.

[0047] refer to Figure 1 , Figure 7 , Figure 8 , Figure 3 and Figure 4 As an option, the relative fixation between the first outer sleeve 4 and the inner sleeve 2 adopts the method of axial limitation + circumferential limitation. Specifically, the upper inner wall of the first outer sleeve 4 is provided with a plurality of first hanging platforms 402 along the circumferential direction, the lower inner wall of the first outer sleeve 4 is provided with a first ring platform 403, the outer wall of the inner sleeve 2 is provided with a second ring platform 201, and the upper end of the inner sleeve 2 and the second ring platform 201 are located between the first hanging platform 402 and the first ring platform 403, thereby limiting the relative axial displacement of the first outer sleeve 4 and the inner sleeve 2, that is, achieving the axial limitation of the first outer sleeve 4 and the inner sleeve 2. The inner wall of the first outer sleeve 4 is provided with a plurality of first anti-rotation teeth 404 along the circumferential direction, and the upper outer wall of the inner sleeve 2 is provided with a plurality of second anti-rotation teeth 202 that cooperate with the first anti-rotation teeth 404 along the circumferential direction, that is, preventing the first outer sleeve 4 and the inner sleeve 2 from rotating relative to each other, and achieving circumferential limitation.

[0048] refer to Figure 1 , Figure 3 , Figure 4 and Fig.13 As an option, the relative fixing method between the bottle mouth and the inner sleeve 2, and the relative fixing method between the bottle mouth and the second outer sleeve 5 also adopts the method of axial limit + circumferential limit. Specifically, the outer wall of the bottle mouth is provided with an annular groove 701, and the inner sleeve 2 is provided with a plurality of first claws 203 protruding from its inner wall and snapping into the annular groove 701 along the circumferential direction, thereby limiting the upward displacement of the upper end bottle body 7, thereby achieving axial limit of the bottle mouth and the inner sleeve 2 after the assembly is completed. The outer wall of the bottle mouth is provided with a plurality of third anti-rotation teeth 702 along the circumferential direction, and the upper inner wall of the inner sleeve 2 is provided with a plurality of fourth anti-rotation teeth 204 cooperating with the third anti-rotation teeth 702, that is, preventing the bottle mouth and the inner sleeve 2 from rotating relative to each other, and achieving circumferential limit.

The lower end inner wall of the second outer sleeve 5 is provided with a plurality of fifth anti-rotation teeth 502 cooperating with the third anti-rotation teeth 702 along the circumferential direction, that is, preventing the bottle mouth and the second outer sleeve 5 from rotating relative to each other, thereby realizing circumferential position limitation.

[0050] refer to Figure 1 , Figure 5 , Figure 6 , Fig. 9 and Fig.10 As an option, the relative fixing method between the lining cover 3 and the second outer sleeve 5 also adopts the method of axial limit + circumferential limit. Specifically, the lower inner wall of the lining cover 3 is provided with a plurality of second hanging platforms 302 along the circumferential direction, the upper outer wall of the second outer sleeve 5 is provided with a third ring platform 503 that abuts against the upper end of the second hanging platform 302, and the lower end of the lining cover 3 abuts against the second outer sleeve 5, thereby limiting the relative axial displacement of the lining cover 3 and the second outer sleeve 5, that is, achieving the axial limit of the lining cover 3 and the second outer sleeve 5. The lower inner wall of the lining cover 3 is provided with an anti-rotation rib 303, and the upper outer wall of the second outer sleeve 5 is provided with an anti-rotation notch 504 that cooperates with the anti-rotation rib 303, that is, preventing the lining cover 3 and the second outer sleeve 5 from rotating relative to each other, and achieving circumferential limit.

[0051] refer to Figure 1 , Figure 5 , Figure 6 , Fig.11 and Fig.12As an option, the relative fixation between the lining cover 3 and the inner cover 6 also adopts the method of axial limit + circumferential limit.
