Detailed implementation manners

[0023] 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.

[0024] A connecting structure of a cap and a bottle body with a built-in anti-theft ring, as Figures 1 to 5 shown, includes a cap body 1, and the cap body 1 is threadedly connected to the bottle mouth of the bottle body, that is, an internal thread 13 is provided in the cap body 1, and a corresponding external thread 14 is provided on the bottle mouth of the cap.

[0025] An anti-theft ring 2 is provided in the cap body 1. It should be noted that by arranging the anti-theft ring 2 in the cap body 1, the overall aesthetics of the cap can be avoided from being affected, and the anti-theft ring 2 can be protected, so as to prevent the anti-theft ring 2 from being directly physically impacted or squeezed by the outside world, resulting in deformation or damage.

[0026] The anti-theft ring 2 includes an upper ring body 21 and a lower ring body 22, and the upper ring body 21 and the lower ring body 22 are detachably connected. Specifically, the upper ring body 21 and the lower ring body 22 are connected by a plurality of break points 11, and the plurality of break points 11 are evenly distributed in the circumferential direction, that is, under the action of an external force, the plurality of break points 11 between the upper ring body 21 and the lower ring body 22 can be broken, so as to realize the separation of the upper ring body 21 and the lower ring body 22.

[0027] The upper ring body 21 is snap-connected to the cap body 1. Specifically, a positioning flange 3 is provided on the outer side wall of the upper ring body 21, and an annular protrusion 4 is provided on the cap body 1, and a positioning protrusion 5 is provided on the inner side wall of the annular protrusion 4. The positioning flange 3 is snap-connected to the positioning protrusion 5, so that the upper ring body 21 is relatively fixed to the bottle body.

[0028] The lower ring body 22 is snap-connected to the bottle body. A positioning flange 6 is provided on the lower ring body 22, and a positioning convex ring 12 is provided on the bottle body. After the bottle cap main body 1 is threadedly connected and tightened with the bottle mouth of the bottle body, the positioning flange 6 is snap-connected to the lower end of the positioning convex ring 12 ( Figure 5 near the position indicated by A), so that the lower ring body 22 and the bottle body remain relatively fixed.

[0029] When the bottle cap main body 1 is rotated to be separated from the bottle mouth of the bottle body, the upper ring body 21 and the lower ring body 22 are separated. It should be noted that when the user rotates the bottle cap main body 1 by an external force and the bottle cap main body 1 is gradually separated from the bottle mouth of the bottle body, since the upper ring body 21 remains relatively fixed with the bottle body main body, and the lower ring body 22 remains relatively fixed with the bottle body, as the bottle cap main body 1 is gradually separated from the bottle mouth of the bottle body, the upper ring body 21 and the lower ring body 22 gradually move away from each other, and several break points 11 between the upper ring body 21 and the lower ring body 22 are disconnected, and the upper ring body 21 and the lower ring body 22 are separated.

[0030] A first guiding surface 7 is provided on the outer side wall of the positioning flange 3. The first guiding surface 7 is an arc surface. The first guiding surface 7 is used to guide the positioning protrusion 5. It should be noted that when installing the anti-theft ring 2, by pressing forcefully, through the guiding action of the first guiding surface 7 on the positioning protrusion 5, it is ensured that the positioning flange 3 can smoothly pass through the positioning protrusion 5 and be snap-connected to the positioning protrusion 5, so that the installation of the anti-theft ring 2 is more convenient and fast.

[0031] The positioning flange 6 is inclined and can be deformed. The positioning flange 6 is preferably made of an elastically deformable plastic material. When the bottle cap main body 1 is threadedly connected and tightened with the bottle mouth of the bottle body, the bottle body passes between the positioning flange 6 and the bottle cap main body 1. The bottle body applies a force to the positioning flange 6 to deform it, thereby expanding the positioning flange 6. The positioning convex ring 12 of the bottle body passes between the positioning flange 6 and the bottle cap main body 1 and is snap-connected to the positioning flange 6 until the bottle cap main body 1 and the bottle mouth of the bottle body achieve threaded connection.

[0032] A second guiding surface 8 is provided on the inner side wall of the positioning flange 6. The second guiding surface 8 is an arc surface. The second guiding surface 8 is used to guide the bottle body. Specifically, when the bottle body passes between the positioning flange 6 and the bottle cap main body 1, through the guiding action of the second guiding surface 8 on the bottle body, it is ensured that the bottle body and the positioning convex ring 12 can smoothly pass between the positioning flange 6 and the bottle cap main body 1, making the threaded connection between the bottle cap main body 1 and the bottle mouth of the bottle body more convenient and fast.

[0033] A plurality of notches 9 are formed on the positioning flange 6, and the plurality of notches 9 are evenly distributed in the circumferential direction, so that the positioning flange 6 is more easily expanded by the bottle body, ensuring that the bottle body and the positioning convex ring 12 can smoothly pass between the positioning flange 6 and the bottle cap main body 1.

[0034] A positioning step 10 is provided on the lower ring body 22, and the step surface of the positioning step 10 abuts against the lower end surface of the annular protrusion 4, so as to ensure the stable relative position relationship between the anti-theft ring 2 and the bottle cap body 1, and it is easier to determine the position of the anti-theft ring 2 during installation, thereby making the installation of the anti-theft ring 2 more convenient and fast, and thus improving the installation efficiency of the anti-theft ring 2.

[0035] A deformable pressing part 15 is provided on the bottle cap body 1. The pressing part 15 is preferably made of an elastically deformable plastic material. A cavity 16 is provided in the bottle cap body 1. A puncturing body 17 is movably arranged in the cavity 16. The bottom of the puncturing body 17 has a plurality of sharp protrusions 18. A storage cavity 19 for placing ingredients is provided in the puncturing body 17. A sealing film 20 is provided on the bottle cap body 1. The sealing film 20 is used to seal the cavity 16. During use, by pressing the pressing part 15 by the user, the pressing part 15 deforms downward and pushes the puncturing body 17 to move, and the puncturing body 17 pierces the sealing film 20 through the sharp protrusions 18, so that the ingredients in the storage cavity 19 fall into the bottle body and are mixed with the liquid.

[0036] The specific embodiments described herein are merely illustrative of the spirit of the present invention; those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
