Inner plug structure of cosmetic bottle

Abstract

An inner plug structure of a cosmetic bottle comprises an elastic bottle body, an elastic ring, a connecting plate, an inserting column and an elastic clamping table. A bottle opening is formed in the top of the elastic bottle body, the elastic ring is arranged on the surface of the inner side of the elastic bottle body, the elastic ring is coaxially arranged at the bottle opening, and a through hole is coaxially formed in the elastic ring; the connecting plate, the inserting column and the elastic clamping table are sequentially connected from top to bottom, the bottom face of the connecting plate abuts against the top face of the elastic bottle body, the inserting column penetrates through the bottle opening and the through hole, the inserting column is of a cylindrical structure and is attached to the bottle opening, the top face of the elastic clamping table abuts against the bottom face of the elastic ring, the elastic clamping table is of an annular structure, and the outer diameter of the elastic clamping table is larger than the diameter of the through hole. The elastic bottle body can be firmly plugged, the sealing effect is effectively guaranteed, cosmetics in the elastic bottle body cannot leak out, external air cannot enter the elastic bottle body, impurities in the external air cannot damage the quality of the cosmetics, and deterioration of the cosmetics cannot be caused.
