Abstract
The invention provides a cosmetic container which allows the cosmetic-loaded cartridge to be freely inserted into and removed from the container body featuring the provision of the following; an internal cylinder which has a spiral groove over the inner circumferential surface and is placed inside the container body; a push rod which moves in the axial direction inside the inner cylinder under the guidance of the spiral groove; a coil spring which loads the push rod in the retracting direction; a chuck which holds the cosmetic and which can be inserted by sliding into a slit guide cylinder inside the cartridge which can be freely inserted into the container body in the axial direction; a coil spring which forces the chuck into the innermost position; and inner spline teeth provided on the internal circumference of the guide cylinder and coupled to the projecting members on the external circumferential surface of the push rod, where the push rod moves forward under the guidance of the spiral groove following the rotation of the container body against the cartridge to eventually allow the cosmetic on the chuck to be extruded from the aperture at the tip of the cartridge.
