Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, and in particular to a controllable, ready-to-use bottle cap. Background Technology

[0002] As consumers increasingly demand personalized and fresh beverages, ready-to-drink (RTD) drinks are gradually becoming a market hotspot. RTD drinks typically store solid beverage pieces, honey, concentrates, and other flavoring ingredients through special bottle caps. When drinking, the flavoring ingredients are mixed with the base liquid (such as water or tea) inside the bottle by operating the cap, achieving "instant preparation and consumption." This not only ensures the independent storage of flavoring ingredients to extend shelf life but also meets users' needs for immediate flavor.

[0003] Most existing ready-to-use beverage bottle caps employ an integrated or two-part structure design, where mixing and opening operations often rely on the same or similar rotation directions. For example, some caps trigger the release of flavoring agents by rotating the top cap, and opening the entire cap also requires rotating the top cap, with the intention of operation only distinguished by the rotation angle or force. This design has a significant drawback: during use, users are highly susceptible to misoperation due to operating habits or distraction—intending to rotate and open the cap to drink the base liquid but accidentally triggering the mixing of flavoring agents with the base liquid; or intending to mix flavoring agents but rotating too much causes the cap to loosen, affecting the mixing effect.

[0004] In addition, the existing bottle cap's guiding and sealing structure design is not perfect: in some products, the guiding components (such as grooves and sliders) used to drive the release of flavoring materials are subjected to uneven force, which can easily cause jamming or tilting, resulting in unstable release of flavoring materials; at the same time, the sealing reliability between the flavoring material storage cavity and the bottle body base liquid is insufficient, which may cause premature leakage of flavoring materials due to transportation bumps or slight operations, affecting the quality of the beverage.

[0005] Therefore, there is an urgent need for a ready-to-use bottle cap that can clearly distinguish between mixing and opening operations, has a stable structure, and provides a reliable seal, in order to solve the problems of confusing operation, poor user experience, and insufficient structural stability in the existing technology, and meet the practical needs of ready-to-use beverages.

[0006] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not have the features of these prior art. On the contrary, this utility model has all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Utility Model Content

Detailed Implementation

[0033] The following is a detailed explanation with reference to the accompanying drawings.

[0034] Example 1

[0035] This utility model provides a controllable, ready-to-use bottle cap, such as... Figure 1 As shown, the bottle cap includes an upper cap 100. The cap also includes a middle cap 200 detachably connected to the upper cap and a lower cap 300 nested within the middle cap 200 and used for rotatably connecting the cap to the bottle body. A spirally extending guide groove 201 is provided on the circumferential outer surface of the middle cap 200. A guide block 301 is provided on the inner surface of the lower cap 300, engaging with the guide groove 201 to slide along it. The extension direction of the guide groove 201 is configured to spiral downwards counterclockwise. The internal thread 302 of the lower cap 300, which rotatably connects to the bottle body, extends in the opposite direction to the guide groove 201. The internal thread 302 is configured to spiral downwards clockwise. This controllable, ready-to-drink bottle cap is used for adding additional flavoring materials, especially for flavored beverages that require immediate preparation and consumption, such as solid herbal pieces, honey, etc. Existing ready-to-drink beverage bottle caps feature staggered rotation to mix with the water inside the bottle. This uniform rotation method makes it easy for the user to accidentally open the cap, intending to open the entire bottle but mistakenly opening the flavoring packet instead. To address this, this application divides the cap into three parts. Through the cooperation of a built-in guide groove 201 and a guide block 301, and by ensuring the guide groove 201 extends in the opposite direction to the internal thread 302, accidental mixing of the beverage is avoided. When the user rotates the cap clockwise, the middle cap 200 moves upward, mixing the flavoring packet and water. When the user rotates the cap counterclockwise, the entire cap detaches from the bottle, allowing the user to drink directly from the water or the mixed beverage.

[0036] like Figures 12 to 14As shown, this utility model separates the bottle cap into three parts: an upper cap 100, a middle cap 200, and a lower cap 300. It also designs a fitting structure between the guide groove 201 of the middle cap 200 and the guide block 301 of the lower cap 300, thus separating the actions of "mixing seasoning materials" and "opening the cap as a whole." Structurally, this avoids the common misoperation problems of existing ready-made bottle caps, ensuring a precise match between the drinker's operational intention and the cap's function. The reverse design of "guide groove 201 spiraling downwards counterclockwise" and "internal thread 302 of the lower cap spiraling downwards clockwise" clarifies the operational logic—clockwise rotation triggers the middle cap 200 to rise and mix the seasoning materials with water, while counterclockwise rotation detaches the cap from the bottle for direct drinking. This makes the operation path clearly identifiable and lowers the barrier to entry for use. The overall structure is adapted to the storage and instant addition needs of solid beverage slices, honey and other additional flavoring materials, perfectly matching the usage scenario of ready-to-drink flavored beverages. It not only ensures the independent storage of flavoring materials, but also enables quick mixing through simple rotation, taking into account both practicality and convenience.

[0037] According to a preferred embodiment, such as Figures 8 to 11 As shown, at least two guide blocks 301 are disposed opposite each other on the inner side of the lower cap 300. Both the vertical upper and lower ends of the guide blocks 301 are provided with inclined surfaces that match the spiral extension direction of the guide groove 201. The arrangement of at least two guide blocks 301 ensures that the middle cap 200 is subjected to balanced force when sliding along the guide groove 201, preventing tilting or jamming of the middle cap 200 due to unilateral force, ensuring the stability of the lifting and lowering movement of the middle cap 200, and thus guaranteeing the uniformity of the release of the seasoning material. The inclined surfaces at both the vertical upper and lower ends of the guide blocks 301 that match the spiral extension direction of the guide groove 201 reduce the sliding friction resistance between the guide blocks 301 and the guide groove 201, preventing jamming or wear during relative movement, and improving the overall service life and smoothness of operation of the cap.

[0038] According to a preferred embodiment, the lower cap 300 includes a first cap body 303 with a guide block 301, a second cap body 304 with internal threads 302, and a third cap body 305 that abuts against the middle cap 200. The first cap body 303, the second cap body 304, and the third cap body 305 are integrally formed, with the first cap body 303 being hollow and penetrating. The integrally formed structure of the lower cap 300 eliminates the need for additional assembly steps, simplifying the bottle cap manufacturing process and improving the overall structural strength of the lower cap 300, avoiding the risk of loosening or breakage caused by splicing multiple parts. The hollow penetrating design of the first cap body 303 provides ample space and a lifting movement channel for the fitting portion 202 of the middle cap 200, ensuring that the middle cap 200 can move smoothly up and down along the guide groove 201 without being obstructed by the internal structure of the lower cap 300.

[0039] According to a preferred embodiment, the second cap 304 and the third cap 305 are nested together. A gap is formed between the second cap 304 and the third cap 305 to accommodate the bottle mouth. An internal thread 302 is disposed in the gap. The nesting of the second cap 304 and the third cap 305 to form a gap for accommodating the bottle mouth allows for precise alignment between the lower cap 300 and the bottle body, avoiding problems such as poor sealing or detachment due to assembly deviations. Distributing the internal thread 302 in the aforementioned gap ensures the firmness of the connection between the lower cap 300 and the bottle body, while also concealing the thread structure internally, reducing damage to the threads from external impacts, and improving the overall aesthetics of the bottle cap.

[0040] According to a preferred embodiment, the third cover 305 is in communication with the first cover 303. The vertically downward end of the third cover 305 is provided with a platform 306 for nesting with the middle cover 200. Several rotatingly arranged flow channels 307 are provided on the circumferential side of the platform 306 on the third cover 305. The design of the third cover 305 being in communication with the first cover 303 provides a continuous space for the lifting and lowering movement of the middle cover 200, preventing the middle cover 200 from getting stuck due to obstruction between the two covers, and ensuring that the seasoning material can be smoothly released from the receiving portion 203 of the middle cover 200. The "platform 306 for nesting with the middle cover 200" provided at the vertically downward end of the third cover 305 can position the middle cover 200, ensuring that the middle cover 200 is stably nested within the third cover 305 in the initial state (before mixing), preventing the middle cover 200 from shaking and causing premature leakage of the seasoning material. The third cap 305 has several rotating flow channels 307 on the circumferential side of the countertop 306. When the middle cap 200 rises and the seasoning material flows out, it can guide the liquid (such as a mixture of water and seasoning material) to flow evenly through the flow channels 307 into the bottle body, ensuring the smoothness of the preparation process.

[0041] According to a preferred embodiment, an annular protrusion 308 is provided on the countertop 306. The diameter of the annular protrusion 308 is smaller than the diameter of the third cover 305 and is located at the vertical end of the countertop 306, forming a space with the inner wall of the third cover 305 to accommodate the middle cover 200. The annular protrusion 308 and the inner wall of the third cover 305 together form a "space to accommodate the middle cover 200", which can further define the nesting position of the middle cover 200, prevent the middle cover 200 from shifting laterally in the initial state, and improve structural stability. The annular protrusion 308 can form a sealing fit with the lower end of the receiving portion 203 of the middle cover 200, preventing the seasoning material (such as powder or liquid) inside the middle cover 200 from leaking out of the gaps, and ensuring the purity and shelf life of the seasoning material.

[0042] According to a preferred embodiment, such as Figures 5 to 7As shown, the middle cover 200 includes a fitting portion 202 with a guide groove 201 on its outer peripheral surface and a receiving portion 203 that fits into the table surface 306 to accommodate the fluid to be added. The fitting portion 202 and the receiving portion 203 are integrally formed. A frame for supporting the guide groove 201 is also provided on the outer peripheral surface of the fitting portion 202. The integrally formed structure of the middle cover 200 simplifies the production process of the middle cover 200, while ensuring the connection strength between the fitting portion 202 and the receiving portion 203, and preventing leakage of seasoning materials due to separation of the two parts. The "frame supporting the guide groove 201" provided on the outer peripheral surface of the fitting portion 202 can enhance the structural strength of the guide groove 201, prevent the guide groove 201 from deforming or breaking due to force during the sliding of the guide block 301, extend the service life of the middle cover 200, and ensure the long-term stable operation of the guide structure. The container 203 is specifically designed to store seasoning materials, achieving physical isolation between the seasoning materials and the liquid inside the bottle. This prevents spoilage or flavor loss caused by pre-mixing, meeting the core requirement of ready-to-drink preparation. It should be noted that the container 203 of the middle cover 200 has an injection molding flow channel on the central axis of its vertical bottom surface to facilitate overall manufacturing.

[0043] According to a preferred embodiment, the receiving portion 203 is cylindrical. The diameter of the vertically downward end of the receiving portion 203 gradually decreases to fit with the annular protrusion 308. The cylindrical shape of the receiving portion 203 maximizes the use of internal space and increases the storage capacity of seasoning materials; simultaneously, the cylindrical structure facilitates processing and shaping, reducing production difficulty and cost. The design of the vertically downward end of the receiving portion 203 "gradually decreasing in diameter to fit with the annular protrusion 308" allows the receiving portion 203 and the annular protrusion 308 to form a tight nested fit, further enhancing the sealing effect, preventing seasoning materials from leaking from the gap between the receiving portion 203 and the third cover 305, while ensuring the coaxiality of the middle cover 200 during lifting and lowering, avoiding displacement.

[0044] According to a preferred embodiment, such as Figures 2 to 4 As shown, the upper cover 100 has an annular groove 101 inside for clamping the vertical edge of the fitting portion 202 of the middle cover 200, and a plurality of engaging teeth 102 are also provided between the annular groove 101 and the inner wall of the upper cover 100. The outer circumferential side of the middle cover 200 also has a step 204 for separating the lower vertical edge of the upper cover 100 and the upper vertical edge of the lower cover 300. Figure 5As shown, the outer periphery of the middle cover 200 is provided with vertical grooves that engage with the snap-fit ​​teeth 102. The annular groove 101 enables a detachable and fixed connection between the upper cover 100 and the middle cover 200, facilitating assembly during production and subsequent disassembly and cleaning by the user (e.g., in reuse scenarios), while preventing accidental separation of the upper cover 100 and the middle cover 200. Several snap-fit ​​teeth 102 between the annular groove 101 and the inner wall of the upper cover 100 enhance the connection between the upper cover 100 and the middle cover 200, preventing the upper cover 100 from loosening or falling off during transportation or operation, and ensuring the sealing of the seasoning material inside the middle cover 200. The "step 204" provided on the outer circumference of the middle cover 200, which separates the vertical lower edge of the upper cover 100 and the vertical upper edge of the lower cover 300, maintains a reasonable gap between the upper cover 100 and the lower cover 300 after assembly, avoiding frictional wear caused by direct contact between the two.

[0045] According to a preferred embodiment, the outer circumferential surface of the lower cover 300 is provided with anti-slip texture 309 for preventing slippage. The anti-slip texture 309 on the outer circumferential surface of the lower cover 300 can increase the friction between the user's hand and the lower cover 300, preventing slippage when rotating the lower cover 300 (whether mixing seasonings or opening the lid as a whole), and ensuring the stability and convenience of operation, especially in situations where hands are wet or oily.
