Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a screw-on powder cap, comprising:

[0030] Bottle cap body 1, which is threadedly connected to the mouth of the beverage bottle;

[0031] The connecting pipe 2 penetrates the bottle cap body 1 and is connected to the inside of the beverage bottle. The connecting pipe 2 is provided with external threads on the side wall outside the bottle cap body 1.

[0032] A fixing ring 4 is fixedly connected to the top of the bottle cap body 1, and a ring groove 6 is formed between the fixing ring 4 and the connecting tube 2.

[0033] The powder assembly 3 is sealed with powder inside and threadedly connected to the connecting pipe 2. To further explain, the powder assembly 3 includes a screw cap 31, which is a cap-shaped structure with an open bottom and a hollow interior. The inner wall of the screw cap 31 is provided with an internal thread, which is adapted to the external thread at the upper end of the outer wall of the connecting pipe 2, so that the screw cap 31 is threadedly connected to the connecting pipe 2. The screw cap 31 is adapted to the annular groove 6. The top of the screw cap 31 is fixedly connected to a powder chamber 32, which is a circular tubular structure. The powder chamber 32 is adapted to the connecting pipe 2 and can rotate inside the connecting pipe 2. The lower end of the powder chamber 32 is fixedly connected to a sealing cap 33, which is made of aluminum foil.

[0034] The sealing component 5 is fixedly connected to the lower end of the inner wall of the connecting tube 2 and is used to break the seal of the powder component 3, so that the powder in the powder component 3 falls into the beverage bottle through the connecting tube 2. Further, the sealing component 5 includes a fixing member 51, which is fixedly connected to the lower end of the inner wall of the connecting tube 2. A sealing tooth 52 is fixedly connected to one side of the top of the fixing member 51. The space formed between the sealing tooth 52 and the inner wall of the connecting tube 2 is adapted to the side wall of the powder container 32.

[0035] It should be noted that this utility model is a screw-on powder cap, such as... Figure 3The diagram shows a cross-sectional view with the powder cap closed. At this point, the lower end of the powder chamber 32 is inserted into the annular groove 6, and the powder chamber 32 is located above the sealing assembly 5. The sealing cap 33 is intact, and the powder is sealed within the powder chamber 32. When the screw cap 31 is rotated, it moves downwards along the connecting pipe 2, its sidewall inserting into the annular groove 6. Simultaneously, this causes the powder chamber 32 to rotate and move downwards within the connecting pipe 2. As the powder chamber 32 moves downwards, the sealing cap... When the powder container 32 rotates and moves downward, the detonating tooth 52 will break the sealing cap 33. The side wall of the powder container 32 will then be inserted into the space formed between the detonating tooth 52 and the inner wall of the connecting tube 2. Since the powder container 32 rotates and moves downward, the rotating sealing cap 33 will be cut and broken by the detonating tooth 52 along its circumference, so that the sealing cap 33 can no longer seal the powder. Under the influence of its own weight, the powder will fall from the powder container 32 into the beverage bottle and mix with the beverage. This explains that when the bottom of the screw cap 31 abuts against the top of the cap body 1, the screw cap 31 cannot rotate further due to the restriction of the cap body 1. At this point, the screw cap 31 causes the powder container 32 to rotate less than one full turn (i.e., 360 degrees). Therefore, the breaking teeth 52 cannot completely cut the connection between the sealing cap 33 and the powder container 32, ensuring that a portion of the sealing cap 33 remains fixedly connected to the side wall of the powder container 32, preventing the sealing cap 33 from falling into the beverage bottle and affecting consumption. Compared to existing screw-on powder caps, this invention achieves automatic powder breaking and mixing through a screw-on operation, eliminating the need for additional tools and making powder and beverage mixing more convenient. The aluminum foil sealing cap effectively prevents moisture and preserves quality, while the breaking structure design ensures residual seal connection, improving drinking safety.
