BACKGROUND OF THE INVENTION

Field of the Invention

The present disclosure relates to a cosmetic applicator.

Description of the Related Art

Cosmetics such as mascara, lipsticks, eyeliner and the like, are applied with cosmetic applicators. Conventional cosmetic applicators include a container which has an opening and a cap, a brush rod extending from the cap to the interior of the container, an applicator body disposed at the tail end of the brush rod, and an inner plug arranged in the opening of the container. The inner plug includes a circular through hole. When the applicators are used to apply cosmetics, the applicator body and the brush rod are taken out of the circular through hole.
The head of the applicator body can be made in various shapes, such as a triangle, a rectangle, a pentagon, an ellipse, a dovetail, and the like. Because the shape of the head does not correspond to the shape of the circular through hole, when the head passes through the circular through hole of the inner plug, cosmetic particles adhering to the surface of the head end up in areas where they do not belong, which leads to waste and causes unsatisfactory user experience.
