The provision of the gasket 3 can make the cover sheet 4 and the inner liner 5 fit tightly, avoiding displacement between the cover sheet 4 and the inner liner 5, and can also further improve the sealing of the cosmetic container and reduce the leakage of cosmetics.

[0081] Optionally, in this embodiment, a handle 20 is fixedly connected or integrally formed on the top of the cover sheet 4. The handle 20 can be provided to facilitate the user to lift the cover sheet 4.

[0082] When the cosmetics in the liner 5 are used up, since the accommodating portion of the liner 5 is clamped on the bottle body 6, one only needs to hold the anti-slip protrusion 19 and rotate the liner 5 to release the clamping between the L-shaped clamping protrusion 17 and the L-shaped clamping groove 18, and then the L-shaped clamping protrusion 17 is moved out of the L-shaped clamping groove 18 through the upper end notch, so that the liner 5 and the bottle body 6 can be separated. The liner 5 can be replaced separately to reduce the cost of use. In addition, since the liner 5 is detachable in design, the processing cost is lower than that of the one-piece design. When a component is damaged, the component can also be replaced separately to avoid waste caused by discarding the entire component.

[0083] The cosmetic container using the replaceable liner in this embodiment has the advantages of low use cost, low processing cost and strong component replaceability.

[0084] The above embodiments are detailed descriptions of optional embodiments of the present invention with reference to the accompanying drawings. Those skilled in the art may make various modifications or changes to the above embodiments without departing from the essence of the present invention, which shall fall within the protection scope of the present invention.
