[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] See Figures 1-5 The present invention provides a rotary sealing bottle cap with a flow channel, comprising a screw cap 1, a bottle mouth 2, and a cap body 4. The screw cap 1 and the cap body 4 cooperate to open or close the bottle mouth 2. The side wall of the screw cap 1 is provided with an air channel 12 and a flow channel 3, which are used to pour liquid when the bottle mouth 2 is open. The air channel 12 and the flow channel 3 are located on the same straight line to facilitate airflow. Through the design of the flow channel and the air channel, the air pressure is balanced when pouring liquid, which improves the smoothness of pouring. The opening of the flow channel 3 is provided with a duckbill to facilitate the pouring of liquid and guide the liquid to flow out in a direction, so as to prevent the liquid from flowing onto the surface of the screw cap when pouring liquid and avoid liquid dripping.

[0023] A fixing cylinder 5 is fixedly connected to the inner wall of the cap 4. The fixing cylinder 5 has an L-shaped cross-section. The top of the bottle mouth 2 is inserted into the cavity formed by the fixing cylinder 5 and the cap 4. The outer wall of the fixing cylinder 5 is tightly attached to the inner wall of the bottle mouth 2 to prevent liquid from overflowing when poured, ensuring the airtight connection between the fixing cylinder 5 and the bottle mouth. A flexible snap ring 6 is fixedly connected to the lower end of the cap 4. The flexible snap ring 6 and the cap 4 have a V-shaped cross-section. The outer wall of the bottle mouth 2 has a groove, and the flexible snap ring 6 snaps into the groove for limiting and fixing the bottle mouth 2 and the cap 4. During installation, simply insert the bottle mouth 2 from the lower end of the cap 4 to compress and deform the flexible snap ring 6 until the groove is located at the flexible snap ring 6. The fixing cylinder 5 and the flexible snap ring 6 cooperate to fix the cap 4 to the bottle mouth 2. When the cap 4 separates from the bottle mouth, the flexible snap ring 6 will break, ensuring anti-counterfeiting.

[0024] A rotating block 7 is fixedly connected to the inner wall of the cap 1, and a spiral protrusion 11 is provided on the outer wall of the cap body 4. The rotating block 7 slides along the spiral protrusion 11 to change the position of the sealing cylinder 14 inside the cap 1. An anti-rotation block 10 is fixedly connected to the outer wall of the cap body 4. The anti-rotation block 10 is located in the middle of the spiral protrusion 11 and is used to limit the movement distance of the limiting protrusion 8. When the cap 1 is rotated, the rotating block 7 slides along the spiral protrusion 11, changing the position of the cap 1 and the cap body 4, until the rotating block 7 is blocked by the anti-rotation block 10. The anti-rotation block 10 ensures that the cap 1 can only rotate a certain angle, and the cap 1 will not be completely unscrewed from the cap body 4, thus preventing hygiene problems caused by opening the cap.

[0025] The cap 4 snaps into the opening of the bottle neck 2. The upper end of the cap 4 is equipped with a sealing cylinder 14, used to close or open the air passage 12 and the flow channel 3. When the outer wall of the sealing cylinder 14 overlaps with the flow channel 3 and the air passage 12, the sealing cylinder 14 blocks the flow channel 3 and the air passage 12. When the top of the sealing cylinder 14 is below the flow channel 3 and the air passage 12, the flow channel 3 and the air passage 12 are connected to the bottle neck 2. This ensures that during use, the cap does not need to be separated from the bottle neck; simply rotating the cap 1 is sufficient, making it simple and convenient to use while ensuring hygiene.

[0026] A limiting protrusion 8 is fixedly connected to the outer wall of the cap 4. An anti-counterfeiting groove 9 is provided at the side end of the limiting protrusion 8, and an anti-counterfeiting strip 13 for verifying whether the cap 1 has been opened is provided at the anti-counterfeiting groove 9. The anti-counterfeiting strip 13 and the cap 1 are integrally formed. The anti-counterfeiting strip 13 has a U-shaped structure. One part of the anti-counterfeiting strip 13 is located inside the anti-counterfeiting groove 9 to prevent the cap 4 from rotating, while the other part is located on the outside of the cap 1. When the cap 1 is rotated, the limiting protrusion 8 squeezes the anti-counterfeiting strip 13 through the anti-counterfeiting groove 9, causing the anti-counterfeiting strip 13 to break. When consumers pick up the bottle, they only need to check whether the anti-counterfeiting strip 1 is present to determine whether the cap 1 has been opened, ensuring security.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
