[0002] Traditional beverages are made by mixing liquid (water) and materials (such as concentrated liquids or powders of various flavors or soluble substances such as honey) in advance and filling them into bottles. In order to extend the shelf life, chemical ingredients such as preservatives are also added, which is not good for health. Therefore, people invented bottle caps with storage bins, in which soluble substances are pre-loaded. When drinking, the soluble substances are taken out of the bottle caps, poured into the beverage bottle, and mixed with the liquid to form a beverage. The traditional method of pouring soluble substances into beverage bottles is manual operation, which is troublesome and unhygienic. Therefore, some people have designed automatic dropping bottle caps, which can automatically drop the soluble substances pre-installed in the bottle caps into the beverage bottle and mix with the liquid, such as the instant bottle cap and the bottle using the bottle cap described in Chinese Patent No.: "201920409350.1". The specific structure of the instant bottle cap is: it has a lower cover, which includes a cover body and a storage barrel, the upper end of the storage barrel is open and connected to the cover body, and the cover body is provided with an internal thread; the upper cover includes a pressing cover and a top column connected to the pressing cover, the pressing cover is connected to the open end of the storage barrel to enclose a sealed storage cavity, the top column is built into the storage cavity and arranged toward the bottom of the storage barrel; before use or drinking, press the pressing cover to push the top column to pierce the storage barrel, so that the solute in the storage cavity leaks or flows out, and it can be used or drunk after shaking and mixing evenly. However, in actual use, it is difficult to press the press cover, and there is a possibility that the press cover cannot be pressed; at the same time, after the storage barrel is punctured by the top column, due to the small punctured hole, the soluble material in the storage cavity is slowly discharged and there is a situation where the discharge is not complete, which affects people's use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0019] As Figures 1-3As shown in the figure, the instant - mixing bottle cap includes an upper cover 1 and a lower cover 2. The lower cover 2 is threadedly installed on the bottle mouth. An active housing 3 is movably arranged in the lower cover 2 through a limiting mechanism 5. The upper cover 1 is always sleeved on the upper part of the lower cover 2 and can rotate relative to the lower cover 2. A storage housing 11 is arranged in the upper cover 1. The active housing 3 includes a mounting part 32 and a sealing plate 31 located below the mounting part 32. The mounting part 32 is threadedly connected to the outer wall of the storage housing 11. The bottom surface of the storage housing 11 is in close contact with the sealing plate 31, so that a sealed storage bin is formed in the storage housing 11, and soluble substances can be placed in the storage bin. When the upper cover 1 is rotated, under the limiting action of the limiting mechanism 5, the active housing 3 can move downward as the upper cover 1 rotates, and the sealing plate 31 moves downward synchronously and gradually separates from the bottom surface of the storage housing 11. At this time, the materials in the storage bin quickly fall into the bottle body and are mixed with the liquid to form the required beverage. When the materials are discharged from the storage bin, the bottle mouth is still in a closed state. At this time, the bottle body can be shaken to make the materials and the liquid mix faster, and then the lower cover 2 is rotated to open the bottle mouth. This instant - mixing bottle cap is more simple and convenient to operate. The materials can completely fall into the beverage bottle and be quickly mixed with the liquid, improving the taste of the beverage and ensuring drinking hygiene.

[0020] In the above - mentioned technical solution: The lower part of the lower cover 2 includes an inner housing 21 and an outer housing 22. The inner wall of the outer housing 22 is provided with an internal thread that cooperates with the bottle mouth, so that the bottle mouth is located between the outer housing 22 and the inner housing 21. The active housing 3 is located inside the inner housing 21.

[0021] In the above - mentioned technical solution: The upper part of the lower cover 2 includes an insertion part 26. The outer peripheral surface of the insertion part 26 is provided with a plurality of first positioning rings 23. The bottom of the first positioning ring 23 is a positioning step 24. A first guiding inclined surface 25 is also made on the first positioning ring 23. The inner wall of the upper cover 1 is provided with a plurality of second positioning rings 13. The upper and lower surfaces of the second positioning rings 13 are respectively made with a second guiding inclined surface 14 and a third guiding inclined surface 15. When the upper cover 1 is sleeved on the insertion part 26, the second positioning ring 13 is located below the positioning step 24. The positioning step 24 positions the upward movement of the second positioning ring 13 to prevent the upper cover 1 from accidentally detaching from the lower cover 2. At this time, the upper cover 1 can only rotate circumferentially relative to the lower cover 2 and cannot move up and down relative to the lower cover 2, preventing the situation where the bottle mouth is accidentally opened by rotating the upper cover 1. The third guiding inclined surface 15 and the first guiding inclined surface 25 cooperate to guide the installation process of the upper cover 1, and the second guiding inclined surface 14 guides the disassembly process of the upper cover 1 from the lower cover 2.

[0022] In the above technical solution: A limiting ring 16 is further provided inside the upper cover 1. The limiting ring 16 is located outside the storage housing 11. The insertion portion 26 is inserted between the inner wall of the upper cover 1 and the limiting ring 16. The bottom of the limiting ring 16 inclines towards the insertion portion 26 and is in close contact with the insertion portion 26. The limiting ring 16 not only positions the installation of the insertion portion 26 but also seals the connection between the lower cover 2 and the upper cover 1, preventing the liquid in the bottle body from leaking out through the gap between the insertion portion 26 and the upper cover 1.

[0023] In the above technical solution: The limiting mechanism 5 includes a plurality of first limiting bumps 51 located on the movable housing 3 and a plurality of second limiting bumps 52 located on the inner wall of the inner housing 21. A limiting groove is formed between two adjacent second limiting bumps 52, and the first limiting bump 51 is located in the limiting groove. The first limiting bump 51 and the second limiting bump 52 limit the movement of the movable housing 3 in the longitudinal direction, preventing the movable housing 3 from rotating relative to the lower cover 2. Guide inclined surfaces are formed on both the first limiting bump 51 and the second limiting bump 52, which facilitate the insertion of the first limiting bump 51 into the limiting groove. The limiting mechanism 5 further includes a limiting flange 53 located at the top of the movable housing 3. During the process of the movable housing 3 moving downward relative to the storage housing 11, when the limiting flange 53 contacts the second limiting bump 52, the movable housing 3 stops moving downward. The limiting flange 53 positions the movement of the movable housing 3, preventing the movable housing 3 from moving downward excessively and separating from the storage housing 11.

[0024] In the above technical solution: A circular insertion groove 34 is formed on the edge of the sealing plate 31, and a sealing groove 35 is formed on the groove wall of the insertion groove 34. A sealing convex ring 12 is formed on the outer wall of the bottom of the storage housing 11. The bottom of the storage housing 11 is inserted into the insertion groove 34, and the sealing convex ring 12 is located in the sealing groove 35. The storage housing 11 is in close contact with the groove wall of the insertion groove 34, realizing the sealing of the storage bin. Of course, a sealing ring can also be provided in the insertion groove 34 to enhance the sealing effect.

[0025] In the above technical solution: The movable housing 3 further includes a plurality of connecting strips 33 connecting the connection and installation portion 32 and the sealing plate 31. One end of the first limiting bump 51 is connected to the limiting flange 53, and the other end extends to the connecting strip 33.

[0026] In the above technical solution: Anti-theft rings 6 are provided at the bottoms of both the upper cover 1 and the lower cover 2. The anti-theft rings 6 and the upper cover 1 and the lower cover 2 are connected by a plurality of connecting bridges 61, thereby preventing the upper cover 1 and the lower cover 2 from loosening and causing liquid leakage during transportation; in addition, it can be judged whether the storage bin has been opened by whether the anti-theft ring 6 and the connecting bridges 61 at the bottom of the upper cover 1 are broken; it can also be judged whether the bottle body has been opened by whether the anti-theft ring 6 and the connecting bridges 61 at the bottom of the lower cover 2 are broken, ensuring the hygiene and use safety of the items in the bottle.

[0027] In the instant-assembly bottle cap, the cooperation among the sealing plate 31, the sealing groove 34 and the sealing convex ring 12 ensures the sealing of the storage bin and prevents the leakage of the materials in the storage bin. By rotating the upper cover 1 to move the sealing plate 31 downward, the discharging of the storage bin is realized, which is labor-saving. At this time, the bottom opening of the storage housing 11 is the discharging port, and the area of the discharging port is greatly increased, so that the discharging speed of the storage bin is faster and the discharging is more thorough. At the same time, since the storage bin is sealed and discharged by the movable sealing plate 31, the capacity of the storage bin is larger. The upper cover 1 can only rotate circumferentially relative to the lower cover 2 and cannot move up and down relative to the lower cover 2, preventing the accidental opening of the bottle mouth when the upper cover 1 is rotated. Such a setting enables the bottle to be directly shaken when the storage bin is discharging, so that the materials and the liquid can be mixed faster without worrying about the leakage of the liquid. When drinking, rotating the lower cover 2 can open the bottle mouth, and the steps are simple and the operation is more reasonable. It can be judged whether the storage bin has been opened by checking whether the anti-theft ring 6 and the connecting bridge 61 at the bottom of the upper cover 1 are broken. It can be judged whether the bottle body has been opened by checking whether the anti-theft ring 6 and the connecting bridge 61 at the bottom of the lower cover 2 are broken, ensuring the hygiene and use safety of the items in the bottle.
