For example, the utility model with the application number 202110109389.3 discloses a bottle cap with high sealing performance and multiple material cavities and a bottle adopting the bottle cap, which comprises an upper cap, a lower cap, a sealing bottom plug and a sealing protective cover. The upper cap comprises an upper cap head and an upper cap barrel, and the lower cap comprises a lower cap body and a lower cap barrel. When in use, the sealing protective cover needs to be opened, and then the upper cap head needs to be pressed downward so that the material falls into the bottle. This design needs additional operation to make the material fall into the bottle after the protective cover is unscrewed, which is troublesome. SUMMARY

[0003] The utility model provides a bottle cap with material adding function to solve one of the above technical problems.

[0004] A bottle cap with material adding function comprises an upper cap, a lower cap and a plug barrel. The upper cap is provided with a side wall and a supporting plate. The side wall is provided with an internal thread. The lower cap is provided with a top side wall and a material storage barrel. The top side wall is provided with an external thread. The external thread of the top side wall is engaged with the internal thread of the side wall. The material storage barrel is provided with an internal thread. The plug barrel is provided with an external thread and a protrusion. The plug barrel is a cylindrical barrel with an open top. The external thread of the plug barrel is engaged with the internal thread of the material storage barrel. The supporting plate can be in contact with the protrusion to drive the plug barrel to rotate when the upper cap rotates. The plug barrel is provided with a plug.

[0005] Further, the lower cap is provided with a bottom side wall. The bottom side wall is provided with an internal thread.

[0006] Further, the bottom of the side wall is provided with an anti-theft ring. The top side wall is provided with a clamping ring.

[0007] Further, the plug is conical, cylindrical or threaded.

[0008] Further, the plug is provided with a flange.

[0009] Compared with the prior art, the utility model only needs to be operated once to make the material fall into the bottle, without other steps, thereby simplifying the operation. BRIEF DESCRIPTION OF DRAWINGS
