[0025] Embodiment 1

[0026] refer to Figure 1-Figure 4 A built-in raw liquid bottle cap structure includes an outer cap 1, an inner cap 2 and an inner sleeve 3. The lower end of the inner sleeve 3 is sleeved on the bottle mouth, and the outer cap 1 is arranged outside the inner cap 2 and the inner sleeve 3.

[0027] On the basis of the above, the present embodiment adds an inner plug 4, which is embedded in the bottle mouth. The inner plug 4 and the internal cavity of the inner plug 4 form a liquid storage cavity 7 for storing the original liquid. The lower end of the inner plug 4 is provided with a sealing port 402. Before the wine bottle is opened, the sealing port 402 is closed, and the original liquid is stored in the liquid storage cavity 7 without contacting the wine in the bottle body 8.

[0028] The upper end of the inner sleeve 3 is connected to the inner cover 2 through a first thread, and a threaded ejector column 5 is slidably connected inside the inner cover 2, and the threaded ejector column 5 is circumferentially fixed relative to the inner cover 2. Specifically, in this embodiment, a second connecting column 201 is provided inside the inner cover 2, and a first tooth is provided on the side wall of the second connecting column 201. A connecting hole is provided at the upper end of the threaded ejector column 2, and a second tooth meshing with the first tooth is provided in the connecting hole, so that the threaded ejector column 5 can slide up and down, but does not rotate relative to the inner cover 2.

[0029] The threaded ejector column 5 is connected to the inner sleeve 3 through the second thread. In this embodiment, the inner sleeve 3 includes a sleeve body 32 and an internal threaded column 31. The sleeve body 32 and the internal threaded column 31 are fixedly connected (for example, a socket connection). The threaded ejector column 5 is connected to the internal threaded column 31 through the above-mentioned second thread, and the thread rotation directions of the first thread and the second thread are opposite.

[0030] The lower end of the threaded ejector column 5 is fixedly connected with a sealing cover 6. After assembly, the sealing cover 6 closes the sealing opening 402 at the lower end of the inner plug 4 to close the liquid storage chamber 7. When opening the cover, after unscrewing the outer cover 1, the inner cover 2 is twisted to open (the inner cover 2 moves up), and the threaded ejector column 5 moves downward while following the rotation of the inner cover 2, driving the sealing cover 6 to move downward, so that the sealing cover 6 is opened and the original liquid flows out. It can be seen that the utility model expands the function of the existing bottle cap, so that the bottle cap can store the original liquid, and when the bottle cap is opened, the original liquid can flow out and mix with the wine in the bottle body 8.

[0031] In this embodiment, the pitch of the first thread is smaller than the pitch of the second thread, so that the downward movement speed of the threaded ejector pin 5 relative to the inner sleeve 3 is faster than the upward movement speed of the inner cover 2 relative to the inner sleeve 3. In practical applications, for example, the first thread is a right-hand thread with a pitch of 2.5 mm; the second thread is a left-hand thread with a pitch of 3 mm.

[0032] The sealing cap 6 includes a cap body 601 and a first connecting column 602, which are integrally formed. The first connecting column 602 is connected to the threaded ejection column 5 by a socket connection. It is easy to understand that in other embodiments, the first connecting column 602 and the threaded ejection column 5 can also be fixedly connected in other ways. After the bottle cap is assembled, the bottle cap is inverted, and the original liquid is injected into the liquid storage chamber 7, and finally the sealing cap 6 is pressed into the threaded ejection column 5, so that the sealing cap 6 closes the sealing port 402.

[0033] The inner plug 4 is provided with a limiting plate 401 below the sealing opening 402. The limiting plate 401 is fixedly connected to the inner plug 4 through a plurality of connecting blocks. A gap 403 for the injection and outflow of the stock solution is formed between adjacent connecting blocks. In this way, the position of the sealing cover 6 is limited to prevent the sealing cover 6 from falling into the bottle body 8 when the cover is opened. In this embodiment, the inner plug 4, the limiting plate 401 and the connecting block are integrally formed. In practical applications, the above structure can be formed by opening a plurality of notches in the side wall of the lower end of the inner plug 4. The through hole is the gap 403 for the injection and outflow of the stock solution.

[0034] Embodiment 2

[0035] This embodiment provides a wine bottle, and the wine bottle cover includes the built-in raw liquid bottle cover structure provided in the first embodiment.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
