[0044] Reference below Figure 1-Figure 5 The bottle cap assembly 10 for a beverage bottle (not shown in the figure) provided according to an embodiment of the present invention is described. The bottle cap assembly 10 is suitable for being connected to the bottle mouth (not shown in the figure) of the beverage bottle. The bottle cap assembly 10 includes: an outer cylinder 100, which is suitable for being connected to the bottle mouth; an inner cylinder 200, which is coaxially sleeved on one end of the outer cylinder 100; a storage cylinder 300, which is coaxially sleeved on the other end of the outer cylinder 100, and at least part of the storage cylinder 300 is sleeved on the inside of the inner cylinder 200, and the storage cylinder 300 is suitable for holding slurry, and the storage cylinder 300 is suitable for rotating in a counterclockwise direction to allow the slurry to flow into the beverage bottle; a limiting mechanism 400, which is arranged between the outer cylinder 100 and the inner cylinder 200, and is suitable for limiting the downward movement of the inner cylinder 200 along the direction of gravity.

[0045] Please continue to see Figure 2 As shown, the outer cylinder 100 can be constructed as a hollow stepped cylindrical structure, with one end of the outer cylinder 100 having a slightly larger cross-sectional area than the other end. A check tooth 110 can be provided on the inner wall of the end with the slightly larger cross-sectional area. This facilitates the outer cylinder 100 to connect to the bottle mouth via the check tooth 110, thereby preventing the liquid in the beverage bottle from leaking. A frustum 120 can be provided at the other end of the outer cylinder 100, and the outer cylinder 100 can be engaged with the storage cylinder 300 via the frustum 120. This arrangement prevents the inner cylinder 200 from sliding downward in the direction of gravity through the engagement between the outer cylinder 100 and the storage cylinder 300.

[0046] It should be noted that the outer wall of the outer cylinder 100 can be provided with anti-slip grooves 130 of uniform intervals, and the anti-slip grooves 130 can be evenly arranged on the outer wall of the outer cylinder 100 along the circumferential direction of the outer cylinder 100. Such a setting can effectively increase the friction of the outer wall of the outer cylinder 100, making it easier for users to pick up the bottle cap assembly 10, and effectively prevent the bottle cap assembly 10 from sliding and falling off, thereby improving the practicality of the bottle cap assembly 10.

[0047] Please continue to see Figure 3As shown, the inner cylinder 200 can be constructed as a hollow cylindrical structure with a through hole 230 at one end. The inner cylinder 200 can be coaxially connected to one end of the outer cylinder 100. The inner cylinder 200 can be made of plastics such as polypropylene and polyethylene. These materials have advantages such as good toughness, resistance to temperature changes, and resistance to chemical corrosion. They are also easy to process and form, and can be designed into various shapes and sizes to meet the needs of beverage bottles of different sizes, thereby improving the practicality and safety of the bottle cap assembly 10.

[0048] The inner cylinder 200 can abut against the outer cylinder 100 to limit the downward movement of the storage cylinder 300, thereby effectively preventing leakage of the product during transportation and improving the practicality and safety of the bottle cap assembly 10.

[0049] Please continue to participate Figure 1 and Figure 4 As shown, the storage barrel 300 can be constructed as a cylindrical structure with a hollow interior, and the cross-sectional areas at the two opposite ends of the storage barrel 300 are different. The structural material of the storage barrel 300 can be consistent with the structural material of the inner barrel 200. Such a setting can improve the production efficiency of the bottle cap assembly 10 and reduce the manufacturing cost of the bottle cap assembly 10.

[0050] One end of the storage barrel 300 may be provided with a threaded interface 330, facilitating threaded connection between the storage barrel 300 and the bottle cap (not shown). A cylindrical outer shell 320 may be provided on the outer sidewall of the storage barrel 300, and an inverted conical protrusion 321 may be provided on the inner sidewall of the cylindrical outer shell 320. The storage barrel 300 can be manually engaged with one end of the frustum 120 of the outer barrel 100 by pressing and locking. This arrangement reduces the workload during assembly and maintenance of the bottle cap assembly 10, thereby improving production efficiency and product quality, while also reducing processing and maintenance costs.

[0051] Please continue to participate Figure 1 and Figure 4 As shown, the end of the storage barrel 300 with a smaller cross-sectional area (i.e., the lower end) can be sleeved with the inner barrel 200, and the lower end of the storage barrel 300 can be set to an inverted frustum shape. The lower end of the storage barrel 300 can be sealed and abutted against the inner bottom of the inner barrel 200, and the other end of the storage barrel 300 can be movably connected to the bottle cap. With this arrangement, the hollow structure inside the storage barrel 300 can serve as a separate sealed space, and the slurry that needs to be added to the beverage bottle (for example: honey, white sugar, coffee or tea, etc.) can be placed in the sealed space inside the storage barrel 300, so that the liquid in the beverage bottle and the slurry contained in the storage barrel 300 can be separately packaged, thereby effectively reducing the amount of preservatives or other substances harmful to the human body added to the beverage.

[0052] Furthermore, the bottle cap assembly 10 can rotate the storage barrel 300 counterclockwise twice when in use. The first counterclockwise rotation is mainly to adjust the inner barrel 200 from the locked state to the unlocked state; during the second counterclockwise rotation, the storage barrel 300 can move upward in the axial direction under the reverse push of the inner barrel 200. The axial direction of the storage barrel 300 is Figure 1 In the direction indicated by Y, the storage barrel 300 rotates to the second positioning groove 250 of the inner barrel 200 and stops. The slurry in the storage barrel 300 can leak out from the lower end of the storage barrel 300, so that it can be released into the beverage bottle through the through hole 230 of the inner barrel 200.

[0053] The limiting mechanism 400 can be respectively arranged on the inner wall of the outer cylinder 100 and the outer wall of the inner cylinder 200, and the inner cylinder 200 and the outer cylinder 100 can be brought into contact with each other by the limiting mechanism 400 so as to reach the first limiting position (the first limiting position is Figure 1 and Figure 4 The inner cylinder 200 is adjusted to a locked state by the abutment of part of the limiting mechanism 400, thereby preventing the storage cylinder 300 from sinking during transportation, and further preventing the slurry in the storage cylinder 300 from leaking.

[0054] According to the bottle cap assembly 10 provided by the present invention, by providing an outer cylinder 100, the outer cylinder 100 can be connected to the bottle mouth through the check tooth 110, thereby preventing the liquid in the beverage bottle from leaking; by providing an inner cylinder 200, the inner cylinder 200 can abut against the outer cylinder 100 to limit the downward movement of the storage cylinder 300, thereby effectively preventing the product from leaking during transportation, and improving the practicality and safety of the bottle cap assembly 10; by providing the storage cylinder 300, the liquid in the beverage bottle and the slurry contained in the storage cylinder 300 can be separately packaged, thereby effectively reducing the amount of preservatives or other substances harmful to the human body; by providing a limiting mechanism 400, the inner cylinder 200 can be adjusted to a locked state, thereby preventing the storage cylinder 300 from sinking during transportation, thereby preventing the slurry in the storage cylinder 300 from leaking.

[0055] Please continue to participate Figure 1-Figure 4 As shown, the limiting mechanism 400 includes: a first limiting protrusion 410, which is provided on the inner wall of the outer cylinder 100; a second limiting protrusion 420, which is provided on the outer wall of the inner cylinder 200, and the first limiting protrusion 410 is suitable for abutting against the second limiting protrusion 420 to limit the downward movement of the inner cylinder 200.

[0056] It should be noted that the first limiting protrusion 410 can be configured as a long strip with a rounded end. The first limiting protrusion 410 can be fixedly connected to the inner sidewall of the outer cylinder 100 by welding or integral molding. The outer cylinder 100 can be positioned and installed with the inner cylinder 200 by using a portion of the protrusion of the first limiting protrusion 410, thereby ensuring accurate installation. The outer cylinder 100 can also abut against the inner cylinder 200 by using another portion of the protrusion of the first limiting protrusion 410 to lock the inner cylinder 200, thereby preventing the inner cylinder 200 and the storage cylinder 300 from sinking, thereby preventing the slurry in the storage cylinder 300 from leaking.

[0057] The second limiting protrusion 420 can be constructed as an irregular strip of varying lengths. The second limiting protrusion 420 can be fixedly connected to the outer wall of the inner barrel 200 by welding or integral molding. The outer barrel 100 can be positioned by abutting the first limiting protrusion 410 with the longer protrusion of the second limiting protrusion 420 to the first limiting position. This arrangement facilitates quick positioning and installation of the outer barrel 100 and the inner barrel 200. After the outer barrel 100 and the storage barrel 300 are installed, the first limiting protrusion 410 can abut the shorter protrusion of the second limiting protrusion 420, i.e., the inner barrel 200 is now locked. The locking of the inner barrel 200 prevents the storage barrel 300 from sinking, thus preventing leakage of the slurry contained in the storage barrel 300, thereby improving the practicality of the bottle cap assembly 10.

[0058] Furthermore, when in use, the storage barrel 300 can be rotated counterclockwise, and the storage barrel 300 can drive the inner barrel 200 to rotate counterclockwise together. At this time, the second limiting protrusion 420 can be away from the first limiting protrusion 410, and the inner barrel 200 can be adjusted from the locked state to the unlocked state. The first limiting protrusion 410 reaches the limiting groove 210, that is, reaches the second limiting position (the second limiting position is Figure 1 and Figure 4 As shown in the second limiting position, the first limiting protrusion 410 presses against the limiting groove 210, thereby preventing the inner cylinder 200 and the storage cylinder 300 from continuing to rotate counterclockwise, thereby limiting the position of the inner cylinder 200. The storage cylinder 300 continues to rotate counterclockwise, and under the reverse push of the inner cylinder 200, the storage cylinder 300 can move upward in the axial direction until it stops at the second positioning groove 250. At this time, the slurry can be released from the lower end of the storage cylinder 300 into the beverage bottle.

[0059] Please continue to participate Figure 1 、 Figure 3 and Figure 4As shown, according to the bottle cap assembly 10 provided in an embodiment of the present invention, the outer wall of the storage barrel 300 has a guide protrusion 310, and the end of the inner barrel 200 close to the storage barrel 300 has a first positioning groove 240 and a second positioning groove 250, and the guide protrusion 310 is suitable for moving from the first positioning groove 240 to the second positioning groove 250.

[0060] Specifically, the guide protrusion 310 can be constructed as a sheet-like structure with an irregular long strip at one end. The guide protrusion 310 can spirally extend upward along the axial direction of the storage barrel 300 to the outer wall of the storage barrel 300. The guide protrusion 310 can be fixedly connected to the storage barrel 300 by welding or integral molding. The number of guide protrusions 310 can be two. During installation, the two guide protrusions 310 can be installed end to end. In this arrangement, the inner barrel 200 can abut against the guide protrusion 310 through the second limiting protrusion 420, thereby achieving initial positioning of the storage barrel 300 and the inner barrel 200, and further achieving rapid installation of the storage barrel 300 and the inner barrel 200.

[0061] Furthermore, the shape of the first positioning groove 240 should match and engage with the shape of the irregular end of the guide protrusion 310. This allows the guide protrusion 310 to engage and position itself with the first positioning groove 240, thereby ensuring that the storage barrel 300 and the inner barrel 200 can quickly reach the correct position during installation. The number of first positioning grooves 240 can be two. This arrangement ensures that the storage barrel 300 and the inner barrel 200 are accurately installed. When the bottle cap assembly 10 is in the initial position, the guide protrusion 310 of the storage barrel 300 engages with the first positioning groove 240 of the inner barrel 200, thereby ensuring that the storage barrel 300 and the inner barrel 200 are accurately positioned, and the inner barrel 200 can lock the storage barrel 300.

[0062] The initial position of the bottle cap assembly 10 is the position when the storage barrel 300 is not rotated.

[0063] The shape of the second positioning groove 250 should match the shape of the irregular end of the guide protrusion 310, which facilitates the engagement and positioning of the guide protrusion 310 with the second positioning groove 250. The second positioning groove 250 also restricts the guide protrusion 310 from sliding clockwise toward the first positioning groove 240, thereby ensuring the correct engagement position of the storage barrel 300 and the inner barrel 200 after the counterclockwise rotation is completed. The number of second positioning grooves 250 can be two, and this arrangement can ensure the accurate engagement of the storage barrel 300 and the inner barrel 200. When the bottle cap assembly 10 is in the final position, the guide protrusion 310 of the storage barrel 300 engages with the second positioning groove 250 of the inner barrel 200, thereby limiting the final counterclockwise rotation position of the storage barrel 300. The provision of the second positioning groove 250 ensures that the storage barrel 300 can rotate counterclockwise to the limit position, thereby improving the reliability and stability of the bottle cap assembly 10.

[0064] The final position of the bottle cap assembly 10 is the position when the storage barrel 300 is rotated counterclockwise twice to the correct position.

[0065] Specifically, the guide protrusion 310 can move from the first positioning groove 240 to the second positioning groove 250 , and the flow rate of the slurry in the storage barrel 300 can be controlled by the rotational sliding distance of the guide protrusion 310 from the first positioning groove 240 to the second positioning groove 250 .

[0066] Please continue to see Figure 3 As shown, according to one embodiment of the present invention, the outer side wall of the inner cylinder 200 further has a limiting groove 210 , and the limiting groove 210 is suitable for cooperating with the first limiting protrusion 410 to limit the rotation of the inner cylinder 200 .

[0067] Specifically, the number of the limiting grooves 210 can be four, and the limiting grooves 210 can be respectively arranged on one side of the second limiting protrusion 420. With such an arrangement, in the process of the storage barrel 300 driving the inner barrel 200 to rotate counterclockwise, that is, the first limiting protrusion 410 of the outer barrel 100 reaches the second limiting position from the first limiting position, and the inner barrel 200 is adjusted from the locked state to the unlocked state. At this time, the inner barrel 200 can move downward along the direction of gravity, and the first limiting protrusion 410 can be pressed into the limiting groove 210. The limiting groove 210 can limit the inner barrel 200 from continuing to rotate counterclockwise while releasing the locking state of the inner barrel 200.

[0068] Please continue to see Figure 1-Figure 4 As shown, according to another embodiment of the present invention, the number of the first limiting protrusion 410, the second limiting protrusion 420 and the limiting groove 210 is multiple, and the multiple first limiting protrusions 410 are respectively arranged in one-to-one correspondence with the multiple second limiting protrusions 420 and the multiple limiting grooves 210.

[0069] Specifically, the number of the first limiting protrusion 410, the second limiting protrusion 420, and the limiting groove 210 can be multiple, and this is not specifically limited in the embodiment of the present invention. The user can select the corresponding number of the first limiting protrusion 410, the second limiting protrusion 420, and the limiting groove 210 according to different needs. It is worth noting that the number of the first limiting protrusion 410, the second limiting protrusion 420, and the limiting groove 210 needs to correspond to each other. Such an arrangement can ensure accurate positioning and limiting of the storage barrel 300, the inner barrel 200, and the outer barrel 100.

[0070] Please continue to see Figure 3 and Figure 4 As shown, according to another embodiment of the present invention, the inner bottom of the inner cylinder 200 has an annular groove 220 , and the annular groove 220 is suitable for being sleeved with the end of the storage cylinder 300 to close the storage cylinder 300 .

[0071] Specifically, the cross-sectional area of the annular groove 220 should be slightly larger than the cross-sectional area of the lower end of the storage barrel 300. This configuration facilitates the sleeve engagement of the storage barrel 300 with the annular groove 220. The depth of the annular groove 220 should be consistent with the height of the rounded cone at the end of the storage barrel 300. This facilitates the sealed sleeve engagement of the storage barrel 300 with the inner barrel 200, preventing leakage of the slurry in the storage barrel 300, thereby improving the practicality of the bottle cap assembly 10.

[0072] Please continue to see Figure 3 As shown, according to an optional embodiment of the present invention, a plurality of through holes 230 are provided on the end of the side wall of the inner cylinder 200 close to the annular groove 220 , and the slurry flows into the beverage bottle through the through holes 230 .

[0073] Specifically, the shape of the through hole 230 can be configured as a tooth shape or other shape, which is not specifically limited in the embodiments of the present invention. The number of through holes 230 can be one or more, and the user can select the appropriate number of through holes 230 according to different application scenarios. Different numbers of through holes 230 can control the outflow of slurry from the storage barrel 300. When the inner barrel 200 reaches the second limit, the storage barrel 300 rotates counterclockwise to move the inner barrel 200 downward in the direction of gravity, and the annular groove 220 can be separated from the lower end of the storage barrel 300; if the storage barrel 300 continues to rotate counterclockwise, the storage barrel 300 can move upward in the axial direction, and the slurry in the storage barrel 300 can be released from the through holes 230.

[0074] According to a further embodiment of the present invention, the bottle cap assembly 10 further includes: a bottle cap connected to an end of the storage barrel 300 facing away from the inner barrel 200 .

[0075] Specifically, the cross-sectional area of the bottle cap (not shown) should be slightly larger than the cross-sectional area of the end of the storage barrel 300 facing away from the inner barrel 200. This arrangement facilitates the flexible connection between the bottle cap and the storage barrel 300. The inner sidewall of the bottle cap may be provided with threads, the path shape of which should match the threaded interface 330 at one end of the storage barrel 300, thereby facilitating a sealed connection between the bottle cap and the storage barrel 300. The bottle cap prevents the slurry in the storage barrel 300 from leaking, thereby improving the practicality and safety of the bottle cap assembly 10.

[0076] In some examples of the present invention, a beverage bottle includes: a bottle body having a bottle mouth; a bottle cap assembly 10 connected to the bottle mouth, and the bottle cap assembly 10 is the above-mentioned bottle cap assembly 10.

[0077] Specifically, the bottle body (not shown) can be constructed in any hollow shape and has a bottle mouth (not shown). The bottle mouth can be cylindrical in shape, and the outer wall of the bottle mouth can be provided with threads to facilitate the connection between the bottle body and the outer barrel 100 of the bottle cap assembly 10.
