[0035] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Embodiment 1

[0037] This embodiment provides a bottle cap assembly for sealingly connecting with the bottle mouth 2 of a beverage bottle, which specifically includes a bottle cap 1 and a storage cap 4. Figure 1 and Figure 2As shown, the inner wall of the bottle cap 1 is provided with an internal thread of the bottle cap that can be threadedly connected with the external thread of the bottle mouth 2, and the inner top surface of the bottle cap 1 is provided with a sealing cylinder 3 extending toward the opening direction of the bottle cap 1. When the bottle cap 1 is sealed and connected to the bottle mouth 2, the sealing cylinder 3 and the storage cover 4 are both located inside the beverage bottle body. A discharge hole 41 is provided on the side wall of the storage cover 4, and the storage cover 4 is detachably inserted into the open end of the sealing cylinder 3, and when the bottle cover 1 is rotated to open the bottle mouth 2, the storage cover 4 and the sealing cylinder 3 can be converted from a first state to a second state. In the so-called first state, the storage cover 4 is inserted into the open end of the sealing cylinder 3, and the cylinder wall of the sealing cylinder 3 closes the discharge hole 41. At this time, a closed space is formed between the sealing cylinder 3 and the storage cover 4, and honey waiting to be dissolved can be stored in isolation in the closed space to achieve the pre-packaging effect of the to-be-dissolved substance; in the so-called second state, the open end of the sealing cylinder 3 is away from the storage cover 4, and the discharge hole 41 on the storage cover 4 is opened. At this time, the interior of the storage cover 4 is connected with the internal space of the beverage bottle body, and the to-be-dissolved substance in the original closed space can flow out from the discharge hole 41 and enter the beverage bottle body to mix with the liquid in the beverage bottle body. In order to ensure the smooth opening of the discharge hole 41 on the storage cover 4, the present solution is also provided with a fixing structure on the outer wall of the storage cover 4, and the storage cover 4 can be relatively fixed with the inner wall of the bottle mouth 2 through the fixing structure, so that when the storage cover 4 and the sealing cylinder 3 are converted from the first state to the second state, the storage cover 4 and the inner wall of the bottle mouth 2 remain relatively fixed. In the above solution, by fixing the storage cover 4 relatively with the inner wall of the bottle mouth 2 through the fixing structure, and at the same time, the sealing cylinder 3 cooperating with the storage cover 4 is arranged on the bottle cover 1, so that based on the threaded connection relationship between the bottle cover 1 and the bottle mouth 2, the honey waiting to be dissolved in the storage cover 4 can be mixed with the liquid in the beverage bottle body by only a single operation process of screwing the bottle cover 1 and opening the bottle mouth 2. At the same time, since the storage cover 4 has a discharge hole 41 connecting the inside of the storage cover 4 and the inside of the beverage bottle body, after the bottle cover 1 is unscrewed, it does not hinder the beverage in the beverage bottle from reaching the bottle mouth 2. As can be seen from the above, the bottle cap assembly of this solution can ensure the isolation and pre-packaging of the to-be-dissolved substance before the bottle mouth is opened through the ingenious structural design of the bottle cap 1, the sealing cylinder 3 and the storage cover 4. At the same time, when it is needed to drink, only the single operation step of unscrewing the bottle cap 1 can achieve the dual effects of opening the bottle cap and automatically injecting the to-be-dissolved substance into the beverage bottle, achieving the effect of instant dissolution and instant drinking after opening the cap. Compared with the existing technology, it effectively simplifies the operating steps of consumers, has the characteristics of convenient use, and can greatly improve the consumer experience. In addition, the entire bottle cap assembly has few and simple structural components, and has the advantages of simple assembly process and low production cost.

[0038] In this embodiment, the side wall of the material storage cover 4 is preferably threadedly connected to the side wall of the sealing cylinder 3, and the thread pair between the material storage cover 4 and the sealing cylinder 3 is preferably the same as the structure of the thread pair between the bottle cap 1 and the bottle mouth 2 (such as rotation direction, pitch, thread, etc.). Based on this, it can be ensured that when the bottle cap 1 is unscrewed, the material storage cover 4 and the sealing cylinder 3 are also in the process of unscrewing, and after the bottle cap 1 is separated from the bottle mouth 2, the material storage cover 4 and the sealing cylinder 3 are also separated from each other.

[0039] In this embodiment, the material storage cover 4 can be inserted outside the opening end of the sealing cylinder 3, or inserted inside the opening end of the sealing cylinder 3. The difference between the two is that the former seals the discharge hole 41 from the inside of the material storage cover 4, and the latter seals the discharge hole 41 from the outside of the material storage cover 4. Considering the requirements of simplified production process and simplified structure, the present embodiment preferably adopts the solution that the material storage cover 4 is inserted outside the opening end of the sealing cylinder 3. Figure 1 and 2 As shown, the inner side wall of the storage cover 4 is provided with a storage cover internal thread 42, and the storage cover internal thread 42 is arranged close to the opening of the storage cover 4, and the discharge hole 41 on the storage cover 4 is arranged close to the cover bottom of the storage cover 4; correspondingly, the outer wall of the open end of the sealing cylinder 3 is provided with an external thread 31 adapted to the storage cover internal thread 42, and when the storage cover 4 and the sealing cylinder 3 are threadedly fastened, the end face of the open end of the sealing cylinder 3 can be sealed against the cover bottom of the storage cover 4, so that the inner wall of the sealing cylinder 3 and the cover bottom of the storage cover 4 are enclosed to form the aforementioned closed space. In the actual assembly process, the bottle cap 1 can be inverted first, that is, the open end of the sealing cylinder 3 is facing upward, and the material to be dissolved is placed in the sealing cylinder 3, and then the storage cover 4 is threadedly connected to the open end of the sealing cylinder 3, so that the assembly of the entire bottle cap assembly and the closed pre-packaging of the material to be dissolved are completed, and the material to be dissolved will not flow out at this time. Taking into account the particularity of the connection method between the storage cover 4 and the bottle mouth 2, during the actual assembly process, the storage cover 4 can also be first placed into the bottle mouth 2 and fixed relatively to the bottle mouth 2, and then the bottle mouth 2 and the storage cover 4 can be threadedly connected to the open end of the sealing tube 3 as a whole. At the same time, the threaded connection between the bottle cover 1 and the bottle mouth 2 is also completed.

[0040] In this embodiment, the center of the bottom of the material storage cover 4 preferably protrudes toward the bottle cap 1 and forms a material storage cover protrusion 43. The material storage cover protrusion 43 can be prismatic, cylindrical or conical, and an annular cavity 44 for accommodating the open end wall of the sealing cylinder 3 is formed between its outer wall and the inner wall of the material storage cover 4. The open end wall of the sealing cylinder 3 is preferably set as a smooth section 32, that is, the outer wall of the smooth section 32 is a conventional circular plane. In the aforementioned first state, the outer surface of the open end wall of the sealing cylinder 3 and the inner wall of the material storage cover 4 are in a smooth interference contact fit to further enhance the sealing between the sealing cylinder 3 and the material storage cover 4.

[0041] In this embodiment, the outer wall of the material storage cover 4 is preferably set as a conical outer wall 45, and the large end of the conical outer wall 45 is located at the opening end of the material storage cover 4. The material storage cover 4 can be interference fit with the inner wall of the bottle mouth 2 through the tapered structural characteristics of the conical outer wall 45, which enhances the connection firmness between the material storage cover 4 and the bottle mouth 2 and can effectively prevent the material storage cover 4 from falling below the bottle mouth 2.

[0042] In this embodiment, the conical outer wall 45 can be specifically a truncated cone or a prism shape, and when the conical outer wall 45 is a prism shape, preferably any edge is an arc transition structure, so that any edge of the prism-shaped outer wall can be in interference contact with the inner wall of the bottle mouth 2.

[0043] In this embodiment, the fixing structure on the material storage cover 4 includes a material storage cover check tooth 46, such as Figure 4 As shown, the outer wall periphery of the storage cover 4 is provided with a plurality of storage cover check teeth 46, and at the same time, the inner wall of the bottle mouth 2 is provided with a plurality of bottle mouth check teeth 21 corresponding to the storage cover check teeth 46, and the bottle mouth check teeth 21 and the storage cover check teeth 46 are opposite in the circumferential direction. When the storage cover 4 and the bottle mouth 2 are assembled, the storage cover 4 or the bottle mouth 2 can be rotated unidirectionally to achieve the meshing connection of the check teeth between the storage cover 4 and the bottle mouth 2. This structure can only achieve the relative rotation of the storage cover 4 and the bottle mouth 2 by rotating the storage cover 4 in a single direction, and the relative rotation of the storage cover 4 and the bottle mouth 2 cannot be achieved in the opposite direction. This opposite direction is also called the "check direction", thereby achieving the check fixing effect of the check teeth. Based on this, the threaded pair structure between the bottle cover 1 and the bottle mouth 2 should ensure that the rotation direction of the bottle cover when opening the bottle cover 1 is the same as the aforementioned "check direction".

[0044] In this embodiment, it is preferred that the material storage cover check teeth 46 are evenly distributed along the circumference of the material storage cover 4 ; correspondingly, the bottle mouth check teeth 21 are evenly distributed along the circumference of the bottle mouth 2 .

[0045] In this embodiment, the bottle cap 1 and the sealing cylinder 3 can be integrally formed, or connected by means of a check tooth, welding, bonding, riveting, etc., as long as the bottle cap 1 and the sealing cylinder 3 can always rotate synchronously and in the same direction. In this solution, the bottle cap 1 and the sealing cylinder 3 are preferably integrally formed, so that the entire bottle cap assembly only has two parts, the bottle cap 1 and the storage cover 4, the overall structure is further simplified, the assembly process is further reduced, and the production and assembly cycle of the bottle cap assembly can be greatly reduced; at the same time, due to the reduction in the number of parts, the use of the corresponding production mold and the number of production will also be reduced, thereby further reducing the production cost.

[0046] When installing the above-mentioned bottle cap assembly, the bottle cap 1 is turned upside down, and the honey concentrated raw materials waiting to be dissolved are loaded into the sealing cylinder 3, and then the storage cover 4 is connected to the sealing cylinder 3 and rotated, and the storage cover 4 and the sealing cylinder 3 are threadedly connected by utilizing the cooperation between the internal thread 42 and the external thread 31 of the storage cover, and this threaded connection can be used as the first sealing of the storage cover 4 and the sealing cylinder 3; after the storage cover 4 and the sealing cylinder 3 are screwed tightly, the smooth surface section 32 of the sealing cylinder 3 and the storage cover 4 are in interference contact and cooperate, so as to realize the second sealing of the storage cover 4 and the sealing cylinder 3, and at the same time, the end face of the opening end of the sealing cylinder 3 is sealed and abutted against the storage cover 4, so as to realize the third sealing of the storage cover 4 and the sealing cylinder 3. The above-mentioned three-sealing structure can effectively prevent the outflow of the honey concentrated raw materials waiting to be dissolved. Finally, the assembled bottle cap assembly is inserted into the bottle mouth 2, and the bottle cap 1 is rotated clockwise to make the bottle cap 1 and the storage cover 4 rotate synchronously. During this rotation process, the bottle cap 1 is tightened with the bottle mouth 2, and the storage cover 4 moves downward, and uses its tapered outer side wall 45 to complete the interference fit with the bottle mouth 2. At the same time, the storage cover check teeth 46 and the bottle mouth check teeth 21 are meshed to complete the one-way clamping of the storage cover 4 and the bottle mouth 2. At this point, the assembly of the entire bottle cap assembly and the assembly of the bottle cap assembly and the bottle mouth 2 are completed.

[0047] When it is time to drink, the bottle cap 1 is rotated counterclockwise. At this time, the storage cover 4 is stationary relative to the bottle mouth 2 due to the counterclockwise rotation force, and the bottle cap 1 drives the sealing cylinder 3 to rotate and move upward synchronously. After the bottle cap 1 is separated from the bottle mouth 2, the storage cover 4 and the sealing cylinder 3 are also separated from each other. The material to be dissolved in the storage cover 4 can flow out from the discharge hole 41 and enter the beverage bottle body to mix with the liquid in the beverage bottle body.

[0048] In the above scheme, through the ingenious structural design of the bottle cap 1, the sealing cylinder 3 and the storage cover 4, the isolated pre-packaging of the to-be-dissolved substance can be ensured before the bottle mouth is opened. At the same time, when it is needed to drink, only the single operation step of unscrewing the bottle cap 1 can be performed, that is, the dual effects of opening the bottle cap and injecting the to-be-dissolved substance into the beverage bottle can be achieved, and the effect of instant dissolution and instant drinking after opening the cap is achieved. Compared with the existing technology, it effectively simplifies the operating steps for consumers, has the characteristics of easy use, and can greatly enhance the consumer experience.

[0049] In addition, this solution reduces the number of parts and assembly steps, reduces material waste and reduces injection molding energy consumption. Compared with the existing technology, it can reduce product costs and production energy consumption by about 35%, thereby improving the market competitiveness of the bottle cap assembly of this solution.

[0050] In addition, compared with the prior art, the present solution reduces the overall height of the packaging of the to-be-dissolved material by nesting the bottle cap 1, the sealing cylinder 3 and the storage cover 4 up and down, thereby increasing the space utilization rate in the beverage bottle by about 10%, thereby achieving the purpose of improving the effective utilization rate of storage and transportation efficiency.

[0051] Furthermore, in this solution, three seals are realized between the sealing cylinder 3 and the material storage cover 4, which greatly improves the sealing reliability of the material to be dissolved compared with the prior art.

[0052] Finally, compared with the prior art, the bottle cap assembly of this solution removes the original intermediate bottle cap, thereby increasing the diameter of the storage cap 4 and maximizing the effective storage space of the storage cap 4 (the storage capacity is doubled), creating conditions for achieving variety diversification of this type of beverage.

[0053] In summary, the utility model can not only reduce resource waste and production costs, simplify the assembly process, but also improve the sealing performance, storage performance and transportation space utilization rate of the bottle cap assembly, and expand the applicability of different types of beverages.

When the storage cap 4 and the bottle mouth 2 are assembled, the storage cap 4 or the bottle mouth 2 can be rotated unidirectionally to achieve the meshing connection of the check teeth between the storage cap 4 and the bottle mouth 2. This structure can only achieve the relative rotation of the storage cap 4 and the bottle mouth 2 by rotating the storage cap 4 in a single direction, and the relative rotation of the storage cap 4 and the bottle mouth 2 cannot be achieved in the opposite direction.
