Cosmetic container

A cosmetic container comprising:

• an inner container having an interior space, the interior space being configured to be filled with a content;
• a dial rotatably coupled at an upper part of the inner container, the dial comprising a dispensing hole and a cutter, the dispensing hole being configured to dispense the content, the cutter being configured to grind the content;
• a screw positioned at a lower part of the dial within the interior space and configured to rotate with the dial as an integrated body;
• a piston inserted around the screw to ascend and descend within the interior space;
• and
• an elastic member positioned at a lower part of the piston and configured to push the piston upward,
• wherein the piston is coupled with the screw by way of a screw joint to maintain a height, and a rotating of the dial causes a disengagement of the screw joint between the piston and the screw to allow the piston to be moved upward by the elastic member,
• wherein the inner container comprises:
• a cylindrical body having an opened top end and a closed bottom end;
• an annular body protrusion extended upward from a bottom surface of the cylindrical body;
• anti-rotation protrusions formed on an outer surface of the annular body protrusion;
• outer guide protrusions formed on an inner side surface of the cylindrical body;
• and
• a coupler peripheral member formed at an upper part of the cylindrical body to form an inner groove, a diameter of the coupler peripheral member being greater than a diameter of the cylindrical body,
• wherein the piston comprises:
• an elevated surface member on which the content is positioned;
• a guide protrusion extended downward from a bottom surface of the surface member, the guide protrusion having a hollow cylinder shape having an opened bottom end;
• first anti-rotation grooves provided on an inner surface of the guide protrusion, wherein the anti-rotation protrusions of the inner container are inserted into the first anti-rotation grooves in order to prevent a rotation of the piston;
• a contact surface member formed on an edge of the elevated surface member, the contact surface member having a hollow cylinder shape having an opened bottom end;
• and
• second anti-rotation grooves provided on an outer surface of the contact surface member, wherein the outer guide protrusions of the inner container are inserted into the second anti-rotation grooves in order to prevent the rotation of the piston,
• wherein the dial comprises:
• a dispensing surface member having the dispensing hole and the cutter;
• and
• a lower peripheral member extended downward from a bottom surface of the dispensing surface member, wherein the lower peripheral member is rotatably inserted into the inner groove of the inner container.
