Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figure 1-8 , the present utility model provides a technical solution:

[0029] A cosmetic bottle for preventing the bottle cap from loosening, including a bottle body 21, a bottle mouth 16 is provided at the top end of the bottle body 21, a connection port 20 is provided on the bottle body 21 corresponding to the lower part of the bottle mouth 16, a bottle cap 1 is installed on the connection port 20, the bottle cap 1 includes a top cover 2, an outer cover 3, a locking mouth 5, a sealing ring 7 and an elastic device, a locking mouth 5 corresponding to the bottle mouth 16 is welded on the top cover 2, an external thread 6 is provided on the locking mouth 5, a sealing ring 7 is provided on the top cover 2 corresponding to the locking mouth 5, an outer cover 3 is welded on the top cover 2, an elastic device is installed on the top cover 2, a female groove 8 is provided on the top cover 2 corresponding to the elastic device, and a groove 9 is provided on the outer wall of the female groove 8. The bottle cap 1 can be screwed off to open the bottle mouth 16 and pour out the cosmetics from the bottle mouth 16. The sealing ring 7 is used to improve the airtightness to prevent the leakage of cosmetics and prevent water from entering. The outer cover 3 forms a cavity inside the bottle cap 1 to prevent water from entering under the action of air pressure.

[0030] Further, the elastic device includes a male ring 10, a flexible connection ring 13, a spring 15, and a spring stopper 4. A convex block 11 corresponding to the groove 9 is provided on the outer side of the male ring 10. The male ring 10 is installed in the female groove 8, and the convex block 11 is slidably clamped with the groove 9. A plurality of groups of first spring holes 12 are formed on the male ring 10, and springs 15 are installed in each of the plurality of groups of first spring holes 12. The other end of the spring 15 is connected to a spring stopper 4. A flexible connection ring 13 is connected between the male ring 10 and the spring stopper 4. A plurality of groups of through second spring holes 14 are formed on the flexible connection ring 13. One end of the spring 15 is welded to the bottom surface of the first spring hole 12, and the other end passes through the second spring hole 14 and is welded to the spring stopper 4. The flexible connection ring 13 should be made of a material with strong ductility so that the flexible connection ring 13 can contract accordingly when the spring 15 contracts.

[0031] Further, an internal thread 17 is provided in the bottle mouth 16, and the external thread 6 is threadedly connected to the internal thread 17. The bottle mouth 16 is provided with an internal thread instead of an external thread, making the outside of the bottle mouth 16 smoother and more beautiful.

[0032] Further, a spring groove 18 corresponding to the spring stopper 4 is formed on the connection port 20, and an outer cover groove 19 corresponding to the outer cover 3 is formed on the connection port 20.

The spring groove 18 should be larger than the spring stopper 4, and the outer cover groove 19 is slightly larger than the outer cover 3. It is recommended that the outer cover groove 19 is ten to thirty silk larger than the outer cover 3. When the bottle cap 1 is installed on the connection port 20, a plurality of groups of springs 15 are in a compressed state. The elastic device spring 15 provides a thrust force to make the connection between the external thread 6 and the internal thread 17 tighter. When screwing the bottle cap 1, it should be pressed down hard to offset the upward force of the elastic device on the bottle cap 1.

[0033] Working principle: When the device needs to be used, press down the bottle cap 1 forcefully, and then rotate the bottle cap 1 clockwise to break the connection between the locking mouth 5 and the internal thread 17. Then the bottle cap 1 can be removed. Tilt the bottle body 21 to pour out the cosmetics from the bottle mouth 16. After use, place the bottle cap 1 on the connection port 20 so that the locking mouth 5 aligns with the bottle mouth 16, the outer cover 3 aligns with the outer cover groove 19, and the spring stopper 4 aligns with the spring groove 18. Press the bottle cap 1 and rotate counterclockwise at the same time to firmly fix the bottle cap 1 on the bottle body 21.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
