[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 A layered rotary cut beverage bottle cap comprises an inner cap 1, a middle cap 2 and an outer cap 3. The inner cap 1 is matched with the bottle mouth of a bottle body 4, the middle cap 2 is rotatably matched with the inner cap 1, the outer cap 3 is covered on the top of the middle cap 2, the middle cap 2 is provided with a receiving cavity 21, a protruding block 11 is provided on the inner side of the inner cap 1, a bottom cover 22 is integrally formed at the bottom of the receiving cavity 21, a groove 23 is provided on one side of the bottom cover 22, and the protruding block 11 extends into the groove 23.

[0024] By providing the accommodating cavity 21 on the middle cover 2, the seasoning can be conveniently poured into the accommodating cavity 21, and then the outer cover 3 is covered to seal the accommodating cavity 21. When the middle cover 2 is matched with the inner cover 1, the middle cover 2 is inserted into the inner cover 1 so that the protruding block 11 is inserted into the groove 23.

[0025] When the flavoring agent in the accommodating chamber 21 needs to flow into the bottle body 4, an external force acts on the middle cover 2, driving the middle cover 2 to rotate. When the middle cover 2 rotates, the groove 23 rotates relative to the protruding block 11. When the side wall of the groove 23 rotates to the protruding block 11, the protruding block 11 acts on the side wall of the groove 23 to cut the corresponding position of the side wall of the groove 23, so that the flavoring agent in the accommodating chamber 21 can flow into the bottle body 4 through the cut, realizing the instant mixing function. When the solution is mixed, the outer cover 3 is opened and the drinker can drink it.

[0026] The front end of the protruding block 11 is provided with an inclined surface 12, and the inclined surface 12 corresponds to the corresponding inner wall of the groove 23. The protruding block 11 and the inner cover 1 are an integral injection molding structure. By providing the inclined surface 12, the sharpness of the side where the protruding block 11 interacts with the groove 23 can be improved, so that the protruding block 11 can better cut the side of the accommodating cavity 21, so that the bottom cover 22 is gradually separated from the side wall of the accommodating cavity 21, which is convenient for the seasoning to flow down quickly.

[0027] like Figure 1 , Figures 4 to 7 As shown, the bottom cover 22 includes a bottom plate 221 and a connecting wall 222. The bottom plate 221 is located directly below the accommodating cavity 21. The bottom plate 221 is connected to the side wall of the accommodating cavity 21 through the connecting wall 222. The thickness of the connecting wall 222 is less than the thickness of the side wall of the accommodating cavity 21. The protruding block 11 corresponds to the connecting wall 222. The bottom cover 22 and the middle cover 2 are an integral injection molding structure. Since the thickness of the connecting wall 222 is smaller than the wall thickness of the accommodating cavity 21, it is more convenient for the inclined surface 12 to cut the connecting wall 222, so that the seasoning can flow into the bottle body.

[0028] The inner cover 1 includes a matching portion 13 and a straight portion 14, the matching portion 13 matches with the bottle mouth of the bottle body 4, the straight portion 14 is located on the inner side of the matching portion 13, the straight portion 14 is sleeved on the outer side of the accommodating cavity 21, and the protruding block 11 is fixed on the inner side of the straight portion 14. The inner cover 1, the matching portion 13 and the straight portion 14 are an integral injection molding structure, and the straight portion 14 can ensure the strength of the protruding block 11, so that the protruding block 11 can cut the bottom cover 22. The straight portion 14 is a hollow structure, which is convenient for the middle cover 2 to be inserted into the inner cover 1 and for the protruding block 11 to match with the groove.

[0029] In actual processing, an internal thread is formed on the inner side of the matching portion 13, and the internal thread can be matched with the external thread of the bottle mouth of the bottle body 4 through the thread, so as to achieve the matching of the inner cover 1 and the bottle body 4. During assembly, the matching portion 13 is located on the outside of the bottle body 4, and the straight tube portion 14 is inserted into the bottle mouth, so that the accommodating cavity 21 of the middle cover 2 is inserted into the straight tube portion 14 and is located in the bottle body, thereby ensuring that the seasoning in the accommodating cavity 21 can flow into the bottle body 4.

[0030] The middle cover 2 is integrally formed with a gripping portion 24, which is arranged outside the inner cover 1, and the outer cover 3 is located above the gripping portion 24. Through the gripping portion 24, it is convenient for the user to act on the gripping portion 24 to drive the middle cover 2 to rotate, which is convenient for operation; when the middle cover 2 rotates, the outer cover 3 on the top of the middle cover 2 can rotate with the middle cover 2, and will not open with the rotation of the middle cover 2.

[0031] The inner cover 1 also includes a horizontal portion 15 and a limiting portion 16. The horizontal portion 15 is located above the matching portion 13 and the straight tube portion 14. The limiting portion 16 is located on the horizontal portion 15. The inner side latching teeth 17 of the limiting portion 16 and the outer side wall of the accommodating cavity 21 are provided with oblique teeth 25. The oblique teeth 25 are arranged correspondingly to the latching teeth 17. The outer side of the accommodating cavity 21 is provided with a limiting step 26, which abuts against the horizontal portion 15. There are multiple oblique teeth 25 and latching teeth 17. By providing the oblique teeth 25 and the latching teeth 17, the middle cover 2 can only rotate in one direction under the limiting action of the latching teeth 17, but cannot rotate in the other direction. Among them, the oblique teeth 25 are located above the limiting step 26.

[0032] When the middle cover 2 is matched with the inner cover 1, the accommodating cavity of the middle cover 2 is inserted into the straight tube portion 14. When the limiting step 26 moves downward to the horizontal portion 15, the limiting step 26 abuts against the horizontal portion 15, so that the middle cover 2 cannot be inserted further downward, which limits the middle cover 2 and moves it into place.

[0033] In actual use, when the outer cover 3 needs to be opened, it can be rotated relative to the middle cover 2, so that the outer cover 3 is rotated open.

[0034] The upper part of the middle cover 2 is provided with an external thread, and the outer cover 3 is provided with an internal thread, and the outer cover 3 and the middle cover 2 are matched through the thread. Thus, the outer cover 3 and the middle cover 2 are convenient to match, so that the outer cover 3 can be a commonly used bottle cap, and the versatility of the outer cover 3 is improved.

[0035] The outer side wall of the accommodating chamber 21 is integrally molded with a sealing ring 27, and the sealing ring 27 abuts against the inner wall of the straight tube portion 14. Therefore, by providing the sealing ring 27, it is convenient to closely adhere to the inner wall of the straight tube portion 14, thereby preventing the liquid from flowing out between the outer side of the accommodating chamber 21 and the straight tube portion 14, and playing a leak-proof role.

[0036] The inner cover 1 is an integral injection molding structure, and the middle cover 2 is an integral injection molding structure. The molding mold of the entire bottle cap is relatively simple, which is conducive to mold opening and helps reduce mold costs, thereby reducing production costs.

[0037] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
