Rotational discharge-type cosmetic container

A rotational discharge-type cosmetic container comprising:

• an outer container having a coupling extension portion formed therein;
• an inner container fitted into the coupling extension portion of the outer container so as to be restricted in rotation to accommodate contents therein;
• a rotary member rotatably coupled to an outer side of the inner container and having at least one discharge port formed therethrough;
• a rotary operation member connected to the rotary member to be rotated together and having a first screw thread formed thereon;
• an elevating member screw-coupled to the rotary operation member, inserted into the coupling extension portion of the outer container so as to be movable in a straight line, and having a second screw thread formed thereon;
• and
• a piston formed inside the inner container and coupled to one side of the elevating member to push and discharge the contents toward the discharge port while being moved in a straight line together with the elevating member, wherein the coupling extension portion of the outer container is formed at a center thereof with an insertion hole into which at least a part of the inner container is inserted, and the insertion hole and the inner container are formed therein with a first locking protrusion and a second locking protrusion, respectively, so as to be locked and coupled to each other.
