Abstract: A cosmetic extrusion case includes a chuck holding a cosmetic, an intermediate cylinder into which the chuck is inserted, a base cylinder into which the intermediate cylinder is inserted. By forming helical grooves in the inner surfaces of the intermediate cylinder and the base cylinder, respectively, the case has a dual structural extruding mechanism. The helical groove of the intermediate cylinder extends to the open end of the intermediate cylinder to allow a projection of the chuck to easily engage with the helical groove from the open end, thereby smoothly inserting the chuck into the intermediate cylinder.
