CONSTITUTION: The container includes an upper body(20), a body(10) and a lid(60) engaged to an upper portion of the upper body. A piston(49) engaged to a screw rod(40) is installed in an interior of the body. A spring(42) and a check valve(43) are installed in a hole(41) formed at an upper end of the screw rod. As the body is rotated, the piston is moved down to press cosmetics and open the check valve closing the hole, thereby forcibly discharging the cosmetics. The body is formed with a groove(14) at an upper end, and the upper body is formed with a resilient member(22) engaging with the groove. |
