Abstract

Disclosed is a rotating discharge type cosmetic container including: an outer case formed therein with a first fixed connection portion; a rotation operating member rotatably coupled to an inside of the outer case and formed therein with a first rotation connecting portion; an inner case detachably coupled to the rotation operating member to accommodate cosmetic contents therein; a rotating member rotatably coupled to the inner case, formed therein with a second rotation connecting portion, and having one surface formed with a discharge port; an operating member connected to the rotation operating member and rotated together with the rotation operating member; a lifting member screw-coupled with the operating member, moved in a straight line within the inner case, and formed therein with a second fixed connection portion; and a piston for moving the cosmetic contents while being moved up and down together with the lifting member.

First claim

What is claimed is:

1. A rotating discharge type cosmetic container comprising:
an outer case formed therein with a first fixed connection portion;
a rotation operating member rotatably coupled to an inside of the outer case and formed therein with a first rotation connecting portion;
an inner case detachably coupled to the rotation operating member to accommodate cosmetic contents therein;
a rotating member rotatably coupled to the inner case, formed therein with a second rotation connecting portion, and having one surface formed with a discharge port;
an operating member connected to the rotation operating member and rotated together with the rotation operating member;
a lifting member screw-coupled with the operating member, moved in a straight line within the inner case, and formed therein with a second fixed connection portion; and
a piston for moving the cosmetic contents while being moved up and down together with the lifting member.

2. The rotating discharge type cosmetic container of claim 1 , wherein an over-cap for opening and closing the rotating member is detachably coupled to the outer case.

3. The rotating discharge type cosmetic container of claim 1 , wherein the first fixed connection portion of the outer case and the second fixed connection portion of the lifting member extend in a detached direction of the inner case so as to be engaged with each other to limit rotation of the lifting member with respect to the outer case.

4. The rotating discharge type cosmetic container of claim 1 , wherein the first fixed connection portion and the second fixed connection portion alternately protrude from facing surfaces between the outer case and the lifting member.

5. The rotating discharge type cosmetic container of claim 1 , wherein the rotation operating member and the inner case are formed thereon with a first detachable portion and a second detachable portion, respectively, so as to be detachably coupled to each other.

6. The rotating discharge type cosmetic container of claim 1 , wherein the first rotation connecting portion of the rotation operating member and the second rotation connecting portion of the rotating member extend in a detached direction of the inner case so as to be engaged with each other to transmit a rotation movement of the rotating member to the rotation operating member.

7. The rotating discharge type cosmetic container of claim 1 , wherein the first rotation connecting portion and the second rotation connecting portion alternately extend by a predetermined section on facing ends between the rotation operating member and the rotating member.

8. The rotating discharge type cosmetic container of claim 1 , wherein the first and second rotation connecting portions have ends formed thereon with first and second guide inclined surfaces, respectively.

9. The rotating discharge type cosmetic container of claim 1 , wherein the rotating member is provided with a cutting blade for cutting a surface of the cosmetic contents.

10. The rotating discharge type cosmetic container of claim 1 , wherein in a refilling process of fastening the inner case and the rotation operating member with each other, the first rotation connecting portion of the rotation operating member is engaged and fitted with the second rotation connecting portion of the rotating member, and simultaneously the first fixed connection portion of the outer case is engaged and fitted with the second fixed connection portion of the lifting member.
