[0016] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Generally, the components of the embodiment of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example

[0019] like Figure 1 , 2As shown, in this embodiment, a bottle cap structure is mainly disclosed, and its main structure includes a bottle mouth 1, a cover body 2, a connecting ring 3 and an anti-counterfeiting ring 4. The cover body 2 is threadedly connected to the bottle mouth 1, and the outer wall of the bottle mouth 1 is provided with a limiting ring groove 11 and a limiting protrusion 12 from bottom to top. A flange 31 that is buckled with the limiting ring groove 11 is provided in the connecting ring 3, and the top of the connecting ring 3 is limitedly abutted with the limiting protrusion 12, and the bottom of the anti-counterfeiting ring 4 is welded to the connecting ring 3. It should be noted that in the prior art, the bottle mouth 1 and the connecting ring 3 are usually integrally formed. In order to meet the requirements of food-grade safety, PET material is usually used. However, due to the characteristics of PET material, the connecting ring 3 and the anti-counterfeiting The ring 4 is prone to poor welding, which is not convenient for production and assembly. Therefore, the utility model sets the bottle mouth 1 and the connecting ring 3 separately, and limits the connecting ring 3 on the outer wall of the bottle mouth 1 by buckling. In this way, the material used for the connecting ring 3 can be distinguished from the bottle mouth 1, and they can be assembled after independent production, which not only solves the food safety problem, but also solves the problem of poor welding. During assembly, the connecting ring 3 is first sleeved on the bottle mouth 1 from bottom to top until the flange 31 is buckled into the limiting ring groove 11, and the top of the connecting ring 3 is abutted against the limiting protrusion 12, then the cover body 2 is installed, and finally the anti-counterfeiting ring 4 is hot-melt welded. The operation is simple and the production efficiency and convenience are improved.

[0020] Furthermore, in the specific implementation, the above-mentioned bottle mouth 1 provided in the embodiment of the utility model is made of PET material, and the connecting ring 3 and the anti-counterfeiting ring 4 are both made of ABS material. The bottle mouth 1 made of PET material has good transparency and durability, and meets the requirements of food grade safety. The connecting ring 3 and the anti-counterfeiting ring 4 made of ABS material have good strength and wear resistance, are easy to weld, and ensure the stability of the bottle cap structure.

[0021] Furthermore, in the specific implementation, the above-mentioned cover body 2 provided in the embodiment of the utility model includes an outer cover 21 and an inner cover 22, the outer cover 21 is sleeved and fixed on the inner cover 22, the bottom end of the outer cover 21 abuts against the top of the anti-counterfeiting ring 4, and the bottom of the inner cover 22 is buckled and limited in the anti-counterfeiting ring 4; specifically, a first protrusion 41 is provided inside the top of the anti-counterfeiting ring 4, and a second protrusion 221 is provided at the bottom of the inner cover 22, and the first protrusion 41 and the second protrusion 221 are interference-fitted; the surfaces where the first protrusion 41 and the second protrusion 221 contact each other are both inclined surfaces; it should be noted that, when the cover body 2 is screwed to open, the cover body 2 gradually rises, and the second protrusion 221 is squeezed and contracted by the first protrusion 41, so that the inner cover 22 gradually breaks away from the limit of the anti-counterfeiting ring 4 and is pulled upward, and due to the restrictions of the first protrusion 41 and the second protrusion 221, it is difficult for the inner cover 22 to be buckled back into the anti-counterfeiting ring 4, thereby realizing the anti-counterfeiting function.

[0022] Furthermore, in a specific implementation, a step surface 32 for positioning and snapping the anti-counterfeiting ring 4 is provided on the connecting ring 3 provided in the embodiment of the utility model, so as to facilitate the positioning and installation of the anti-counterfeiting ring 4 and improve the accuracy of assembly.

[0023] Furthermore, in a specific implementation, the anti-counterfeiting ring 4 and the connecting ring 3 provided in the embodiment of the utility model are spot-welded at even intervals. When the cover body 2 is opened with great force, the connection between the anti-counterfeiting ring 4 and the connecting ring 3 is easily damaged, causing the connecting seam to break, thereby further improving the anti-counterfeiting performance.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
