Disclosed herein is a piston for an airless-type cosmetic container. The piston disposed in the container is moved upwards by operation of an airless pump to discharge contents, and a silicone packing part is integrated with a piston main body along a periphery thereof using an insert molding method, thus improving productivity. In addition, instead of direct contact between the container and the piston, the silicone packing part surrounding the piston uniformly comes into close contact with the container, thus ensuring superior sealability between the piston and the container, regardless of the shape of the piston, thereby preventing the leakage of the contents and efficiently discharging the contents. Moreover, unlike typical cosmetic containers, the container can be implemented in various shapes, thereby maximizing marketability. |
