[0002] like Figure 1 As shown, the existing bottle caps can be easily removed after being heated, and the anti-counterfeiting measures will be ineffective after the caps are removed. This means that the bottle can be easily opened and the beverage inside can be poured out, posing a risk of substitution and counterfeiting. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bottle cap that prevents it from falling off.

[0004] The purpose of this utility model is achieved through the following technical solution: an anti-detachment bottle cap, including a plastic ring, the top of the plastic ring having a cap, a fastener provided inside the cap, the fastener having an anti-detachment part, the plastic ring being provided on the outside of the bottle mouth, and an outer cap being provided outside the plastic ring, with a protrusion on the inner side of the outer cap located below the anti-detachment part.

[0005] Preferably, the anti-detachment part is a retaining ring, which is located at the lower end of the fastener and is horizontally arranged on the side of the fastener, with the boss located below the retaining ring.

[0006] Preferably, the retaining ring is located above the threaded section on the bottle neck.

[0007] Preferably, a ring is also provided on the outside of the bottle mouth, the ring is located below the threaded section, and the ring is located inside the plastic ring.

[0008] Preferably, both the ring and the fastener are made of stainless steel.

[0009] Preferably, the outer side of the plastic ring is provided with a groove, and the boss is located in the groove.

[0010] The present invention has the following advantages: The present invention provides a fastener inside the cover at the top of the plastic ring, and the anti-detachment part on the fastener is located above the outer cover protrusion. Thus, when the plastic ring is heated, the anti-detachment part can also limit the protrusion, thereby preventing the outer cover from falling off. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0018] 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 claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] In this embodiment, as Figure 2 and Figure 3 As shown, an anti-detachment bottle cap includes a plastic ring 6, a cap 7 at the top of the plastic ring 6, a fastener 4 inside the cap 7, and an anti-detachment part on the fastener 4. The plastic ring 6 is located on the outside of the bottle mouth 2, and an outer cap 8 is provided outside the plastic ring 6. A protrusion 9 on the inner side of the outer cap 8 is located below the anti-detachment part. Preferably, a groove 10 is provided on the outer side of the plastic ring 6, and the protrusion 9 is located in the groove 10. By providing the fastener 4 inside the cap 7 at the top of the plastic ring 6, and positioning the anti-detachment part on the fastener 4 above the protrusion 9 of the outer cap 8, the anti-detachment part can also limit the protrusion 9 when the plastic ring 6 is heated, thereby preventing the outer cap 8 from falling off. In this embodiment, the fastener 4 is installed inside the cap 7 using an injection molding process.

[0024] Furthermore, such as Figure 5 As shown, the anti-detachment part is a retaining ring 5, which is located at the lower end of the fastener 4 and is horizontally positioned on the side of the fastener 4. The boss 9 is located below the retaining ring 5. Specifically, the retaining ring 5 is horizontally positioned on the side of the fastener 4, so that when the plastic ring 6 is heated, the retaining ring 5 can better limit the boss 9. Furthermore, the retaining ring 5 is located above the threaded section 3 on the bottle mouth 2.

[0025] In this embodiment, as Figure 4 As shown, a ring 1 is also provided on the outer side of the bottle mouth 2. The ring 1 is located below the threaded section 3 and inside the plastic ring 6. Specifically, the ring 1 here is the existing ring used in bottle caps, and its structure and function are existing. No improvements have been made to it, so it will not be described in detail here. Furthermore, both the ring 1 and the fastener 4 are made of stainless steel. Specifically, the main purpose of making both the ring 1 and the fastener 4 of stainless steel is to prevent deformation caused by heating.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
