Technical Field
[0001] This utility model relates to the field of packaging and discloses a bottle cap assembly and a beverage bottle. Background Technology
[0002] As beverage bottles become increasingly versatile, some bottle caps are designed to store substances like honey and jam. When a drink is desired, a valve inside the cap is opened, allowing the contents to enter the bottle. There are various ways to open the valve, such as pressing or rotating. Currently, bottle caps with rotating valves require aligning the inner and outer caps before pressing them together to connect the rotating mechanism. This assembly method is cumbersome and inefficient, hindering production efficiency. Therefore, a more convenient bottle cap assembly method is urgently needed. Utility Model Content
[0003] The purpose of this utility model is to provide a bottle cap assembly and a beverage bottle to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0004] A bottle cap assembly according to a first aspect of the present invention includes: an inner connecting sleeve having a connecting section protruding from its top along a direction away from the axis of the inner connecting sleeve, a connecting groove on the outer side of the connecting section, and an installation port communicating with the connecting groove on the bottom side of the connecting section, the connecting groove extending spirally upward around the connecting section; an outer connecting sleeve fitted onto the outer side of the inner connecting sleeve, a bottom plate at the bottom end of the outer connecting sleeve, a liquid outlet hole on the outer side of the bottom of the outer connecting sleeve, a connecting block on the inner side of the outer connecting sleeve, the connecting block being located within the connecting groove, wherein when the connecting block moves upward to the top of the connecting groove, the bottom plate closes the bottom end of the inner connecting sleeve, and when the connecting block moves downward to the bottom of the connecting groove, the bottom plate opens the bottom end of the inner connecting sleeve; and a cap disposed at the top end of the inner connecting sleeve.

[0008] According to some embodiments of the present invention, an anti-detachment protrusion is provided at the bottom of the connecting groove. When the connecting block moves toward the mounting port, it abuts against the anti-detachment protrusion. The side of the anti-detachment protrusion away from the axis of the inner connecting sleeve is inclined downward to the bottom of the connecting groove.
[0009] According to some embodiments of the present invention, the cap includes a connecting cylinder and an upper cover body. The connecting cylinder is sleeved on the outside of the inner connecting sleeve and located above the outer connecting sleeve. The connecting cylinder protrudes from the top of the inner connecting sleeve and forms a limiting shoulder along the axis of the inner connecting sleeve. A liquid outlet is provided on the inner side of the limiting shoulder. The upper cover body is flipped and connected to the limiting shoulder. The upper cover body can be rotated to open or close the liquid outlet.
[0010] According to some embodiments of the present invention, the outer connecting sleeve includes an outer cylinder, a connecting ring connected to the inner side of the bottom of the outer cylinder, and an inner cylinder connected to the inner side of the connecting ring. The inner cylinder protrudes downward from the outer cylinder, and a fixing groove is formed between the outer cylinder and the inner cylinder. The bottom plate is connected to the bottom end of the inner cylinder, the liquid outlet is located on the outer side of the bottom of the inner cylinder, and the connecting block is located on the inner side of the outer cylinder and above the connecting ring.
[0011] According to some embodiments of the present invention, the bottom outer side of the inner connecting sleeve is provided with a plurality of annular ribs along the vertical direction, and the plurality of annular ribs respectively abut against the inner side of the inner cylinder.
[0012] According to some embodiments of the present invention, an annular sealing groove is provided on the top side of the base plate, and when the connecting block moves upward to the top of the connecting groove, the bottom end of the inner connecting sleeve is inserted into the annular sealing groove.

[0028] Reference Figures 1 to 3 According to a first aspect of the present invention, a bottle cap assembly includes an inner connecting sleeve 100, an outer connecting sleeve 200, and a cap. The top of the inner connecting sleeve 100 has a connecting section 110 protruding in a direction away from the axis of the inner connecting sleeve 100. A connecting groove 111 is provided on the outer side of the connecting section 110, and an installation port 112 communicating with the connecting groove 111 is provided on the bottom side of the connecting section 110. The connecting groove 111 extends spirally upward around the connecting section 110. Naturally, the outer diameter of the bottom of the inner connecting sleeve 100 is smaller than the outer diameter of the protruding connecting section 110, forming a transition at the bottom end of the connecting section 110. The inner connecting sleeve 100 has an annular stepped structure. The outer connecting sleeve 200 is sleeved on the outside of the inner connecting sleeve 100. The bottom end of the outer connecting sleeve 200 is provided with a bottom plate 210. The bottom outer side of the outer connecting sleeve 200 is provided with a liquid outlet hole 220. The inner side of the outer connecting sleeve 200 is provided with a connecting block. The connecting block is located in the connecting groove 111. When the connecting block moves upward to the top of the connecting groove 111, the bottom plate 210 closes the bottom end of the inner connecting sleeve 100. When the connecting block moves downward to the bottom of the connecting groove 111, the bottom plate 210 opens the bottom end of the inner connecting sleeve 100. A cap is provided at the top end of the inner connecting sleeve 100.
[0029] As described above, during overall assembly, the outer connecting sleeve 200 is fitted onto the outside of the inner connecting sleeve 100. The connecting block on the inner side of the outer connecting sleeve 200 is fitted into the connecting groove 111 from the mounting port 112 on the bottom side of the connecting section 110. By rotating the outer connecting sleeve 200 relative to the inner connecting sleeve 100, the connecting block moves along the extension direction of the connecting groove 111. When the connecting block moves upward to the top of the connecting groove 111, the bottom plate 210 at the bottom of the outer connecting sleeve 200 closes the bottom of the inner connecting sleeve 100. At this time, a cavity for accommodating materials is formed between the inner connecting sleeve 100 and the bottom plate 210. Materials can be loaded into the cavity. Then, the cap is placed on the top of the outer connecting sleeve 200 to cover and seal the cavity, thus completing the assembly of the bottle cap assembly. The outer connecting sleeve 200 can be inserted into the external bottle. When it is necessary to pour the material from the bottle cap assembly into the bottle, the outer connecting sleeve 200 is positioned relative to the inner connecting sleeve 100. Reverse rotation causes the connecting block to move downwards to the bottom of the connecting groove 111. At this time, the bottom plate 210 opens the bottom end of the inner connecting sleeve 100, and the material inside the inner connecting sleeve 100 enters the bottle from the liquid outlet 220 on the outer side of the bottom of the outer connecting sleeve 200. This allows the material inside the bottle cap assembly to mix with the solution in the bottle. When drinking is required, the cap is opened, and the contents can be poured out from the top of the inner connecting sleeve 100. Thus, when assembling the bottle cap assembly, the connecting block is inserted into the connecting groove 111 from the mounting port 112 on the bottom side of the connecting section 110, and the inner connecting sleeve 100 and the outer connecting sleeve 200 are further rotated and fitted together to achieve mutual assembly of the outer connecting sleeve 200 and the inner connecting sleeve 100 and to close the bottom of the inner connecting sleeve 100. The overall structure is simple, reducing the steps of aligning and pressing the outer connecting sleeve 200 and the connecting sleeve, simplifying the production process, and thus effectively improving the efficiency of bottle cap assembly.
[0030] To better maintain the closed state of the base plate 210 over the bottom end of the inner connecting sleeve 100, in this embodiment, a positioning groove 113 is provided on the outer side of the connecting segment 110. The positioning groove 113 is connected to the top end of the connecting groove 111 and extends circumferentially along the inner connecting sleeve 100. When the connecting block rotates to the top end of the connecting groove 111, the outer connecting sleeve 200 continues to rotate relative to the inner connecting sleeve 100, causing the connecting block to enter the positioning groove 113. At this time, the connecting block can better maintain its relative height with the inner connecting sleeve 100, thereby keeping the base plate 210 closed over the bottom end of the inner connecting sleeve 100.
[0031] In practical applications, the base plate 210 is provided with an upward protrusion. When the base plate 210 closes the bottom end of the inner connecting sleeve 100, the protrusion enters the interior of the inner connecting sleeve 100, strengthening the tightness of the fit between the two and further improving the sealing performance of the fit between the bottom end of the inner connecting sleeve 100.
[0032] The outer connecting sleeve 200 and the inner connecting sleeve 100 achieve relative positioning through the cooperation of connecting blocks and connecting grooves 111. In the above embodiment, there may be only one connecting block and one connecting groove 111. However, to further improve the tightness of the connection, in this embodiment, multiple connecting grooves 111 are provided circumferentially on the outer side of the connecting segment 110, and multiple connecting blocks are provided circumferentially on the inner side of the outer connecting sleeve 200. The multiple connecting blocks are located in the multiple connecting grooves 111. For example, there may be two connecting grooves 111 and two connecting blocks. In this case, the two connecting blocks are located on both sides of the outer connecting sleeve 200 and cooperate with the connecting grooves 111 on both sides of the inner connecting sleeve 100, making the connection between the outer connecting sleeve 200 and the inner connecting sleeve 100 more stable and tighter.
[0033] To prevent the inner connecting sleeve 100 from separating entirely from the outer connecting sleeve 200 during use, in this embodiment, an anti-detachment protrusion 114 is provided at the bottom of the connecting groove 111. When the connecting block moves toward the mounting port 112, it abuts against the anti-detachment protrusion 114. The side of the anti-detachment protrusion 114 away from the axis of the inner connecting sleeve 100 is inclined downward to the bottom of the connecting groove 111. After the connecting block enters the connecting groove 111 from the mounting port 112, it moves to the anti-detachment protrusion 114. At this time, the side of the anti-detachment protrusion 114 away from the axis of the connecting sleeve forms an inclined guide surface. The guide surface presses the connecting block away from the axis of the inner connecting sleeve 100, so that the anti-detachment protrusion 114 can pass through the connecting groove 111. When it is necessary to rotate the connecting block to the mounting port 112, the anti-detachment protrusion 114 blocks and limits the connecting block, preventing the connecting block from coming out of the connecting groove 111, thereby preventing the inner connecting sleeve 100 and the outer connecting sleeve 200 from separating during use.
[0034] There are several ways to set the cap at the top of the connecting cylinder 310. For example, the cap is connected to the top of the connecting cylinder 310 by a thread. In this embodiment, the cap includes the connecting cylinder 310 and the upper cover body 320. The connecting cylinder 310 is sleeved on the outside of the inner connecting sleeve 100 and located above the outer connecting sleeve 200. The connecting cylinder 310 protrudes from the top of the inner connecting sleeve 100 and forms a limiting shoulder 311 along the axis of the inner connecting sleeve 100. A liquid outlet 312 is provided on the inner side of the limiting shoulder 311. The upper cover body 320 is flipped and connected to the limiting shoulder 311. The upper cover body 320 can be rotated to open or close the liquid outlet 312. The connecting tube 310 is installed at the top of the connecting tube 310. The limiting shoulder 311 at the top of the connecting tube 310 abuts against the top of the inner connecting sleeve 100, which can limit the downward movement of the connecting tube 310 when it is sleeved on the outside of the inner connecting sleeve 100. When not in use, the upper cover 320 is located at the dispensing nozzle 312, blocking and sealing the dispensing nozzle 312. When drinking is needed, the upper cover 320 is rotated to open the dispensing nozzle 312. In this way, the user can operate with one hand when opening the cover, which improves the convenience of use and reduces the situation where the upper cover 320 is placed randomly and the internal residual liquid drips out.
[0035] To facilitate the connection of the outer connecting sleeve 200 to the bottle, in this embodiment, the outer connecting sleeve 200 includes an outer cylinder 230, a connecting ring 240 connected to the inner side of the bottom of the outer cylinder 230, and an inner cylinder 250 connected to the inner side of the connecting ring 240. The inner cylinder 250 protrudes downward from the outer cylinder 230, and a fixing groove is formed between the outer cylinder 230 and the inner cylinder 250. The bottom plate 210 is connected to the bottom end of the inner cylinder 250, the liquid outlet 220 is located on the outer side of the bottom of the inner cylinder 250, and the connecting block is located on the inner side of the outer cylinder 230 and above the connecting ring 240. Because the inner connecting sleeve 100 has an outwardly protruding connecting section 110, which is concave at the bottom end, the outer connecting sleeve 200 includes an outer cylinder 230, a connecting ring 240, and an inner cylinder 250 to better fit the inner connecting sleeve 100. The connecting ring 240 fits the concave bottom end of the connecting section 110, while the inner cylinder 250 fits against the bottom outer side of the inner connecting sleeve 100, and the outer cylinder 230 fits against the top outer side of the inner connecting sleeve 100. A fixing groove formed between the outer cylinder 230 and the inner cylinder 250 facilitates connection and positioning with the bottle neck. In practical applications, an internal thread can be provided on the inner bottom side of the outer cylinder 230 for threaded connection with the bottle.
[0036] Since the inner cylinder 250 needs to rotate relative to the inner connecting sleeve 100, if the two are tightly pressed together, it will increase rotational friction, making it difficult to rotate them relative to each other. Therefore, in this embodiment, the bottom outer side of the inner connecting sleeve 100 is provided with a plurality of annular ribs 120 along the vertical direction, and the plurality of annular ribs 120 abut against the inner side of the inner cylinder 250 respectively. By the plurality of annular ribs 120 abutting against the inner side of the inner connecting sleeve 100, a multi-layer seal can be formed, improving the tightness of the connection between the inner connecting sleeve 100 and the inner cylinder 250, and by reducing contact friction, smooth rotation between the inner connecting sleeve 100 and the inner cylinder 250 can be ensured.
[0037] To further improve the sealing performance of the base plate 210 to the bottom end of the inner connecting sleeve 100, in this embodiment, an annular sealing groove is provided on the top side of the base plate 210. When the connecting block moves upward to the top of the connecting groove 111, the bottom end of the inner connecting sleeve 100 is inserted into the annular sealing groove. The mutual cooperation between the bottom end of the inner connecting sleeve 100 and the annular sealing groove enables rapid pairing and connection of the inner connecting sleeve 100, improving the tightness of the connection. In practical applications, a perimeter can be provided around the boss on the base plate 210 at intervals, forming an annular sealing groove between the perimeter and the boss.
[0038] To increase the flow rate of material from the inner connecting sleeve 100 into the bottle, and the flow rate of solution from the bottle into the inner connecting sleeve 100, in this embodiment, multiple outlet holes 220 are provided around the outer connecting sleeve 200. When material needs to be poured into the bottle, the material in the inner connecting sleeve 100 is simultaneously poured into the bottle from multiple outlet holes 220. When drinking, the solution in the bottle can enter the inner connecting sleeve 100 from multiple outlet holes 220 and be poured out from the inner connecting sleeve 100.
[0039] A beverage bottle according to a second aspect of the present invention includes a bottle body and the aforementioned bottle cap assembly, wherein the bottle body is connected to the outer connecting sleeve 200.
[0040] In this beverage bottle, when installing the cap assembly, the connecting block is inserted into the connecting groove 111 from the mounting port 112 on the bottom side of the connecting section 110, and the inner connecting sleeve 100 and the outer connecting sleeve 200 are further rotated to engage with each other, thereby realizing the mutual assembly of the outer connecting sleeve 200 and the inner connecting sleeve 100 and achieving the closure of the bottom of the inner connecting sleeve 100. The overall structure is simple, reducing the steps of aligning and pressing the outer connecting sleeve 200 with the connecting sleeve, simplifying the production process, and thus effectively improving the efficiency of the overall assembly.
[0041] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described.
