The cosmetic container includes a container, a lower cap that is screw-coupled to the opening section of the container, a packing body being inserted and fixed to a hole formed in the center of the lower cap, a middle cap that is rotatably coupled to the upper portion of the lower cap and has a shaft tube formed in the center thereof, the shaft tube having a cutaway portion formed by cutting in the position corresponding to an open hole of the packing body, a brush that is formed in the upper portion of the shaft tube, and an external cap that is coupled to the upper portion of the middle cap.
