Cosmetic container

Abstract

Disclosed herein is a cosmetic container. The cosmetic container includes: a dial configured to receive rotating force; a container part configured such that cosmetics are accommodated in the lower side thereof and the dial is relatively rotatably disposed in the upper side thereof; a piston arm disposed inside the container part, and configured to be selectively lifted and lowered by the rotation of the dial; a piston disposed to come into tight contact with the inner wall of the container part, and configured to be coupled to the lower portion of the piston arm and to be selectively lifted and lowered; and a transfer tube disposed inside the container part, and configured such that a transfer flow path is formed therein; wherein when the piston arm and the piston are lowered and press the cosmetics, the cosmetics enter into the lower portion of the transfer tube and are discharged.

What is claimed is: 
     
         1 . A cosmetic container, comprising:
 a dial configured to receive rotating force from a user;   a container part configured such that cosmetics are accommodated in a lower side thereof and the dial is relatively rotatably disposed in an upper side thereof;   a piston arm disposed inside the container part, and configured to be selectively lifted and lowered by rotation of the dial relative to the container part;   a piston disposed to come into tight contact with an inner wall of the container part, and configured to be coupled to a lower portion of the piston arm and to be selectively lifted and lowered along with the piston arm; and   a transfer tube disposed inside the container part, and configured such that a transfer flow path through which the cosmetics are transferred is formed therein in a longitudinal direction of the container part;   wherein when the piston arm and the piston are lowered and press the cosmetics by the relative rotation of the dial, the cosmetics enter into a lower portion of the transfer tube and are discharged through the transfer flow path.   
     
     
         2 . The cosmetic container of  claim 1 , wherein:
 a lifting and lowering guide portion having a non-circular section is formed in one area of the transfer tube, and a through portion corresponding to the lifting and lowering guide portion is formed inside the piston arm; and   the piston arm is guided through selective lift and lowering in such a manner that the lifting and lowering guide portion is inserted into the through portion and the piston arm is prevented from being rotated during the relative rotation of the dial.   
     
     
         3 . The cosmetic container of  claim 1 , wherein corresponding threads are formed on an inner circumferential surface of the dial and an outer circumferential surface of the piston arm, and the dial and the piston arm are screwed to each other. 
     
     
         4 . The cosmetic container of  claim 1 , wherein at least one opening is formed through an upper portion of the container part in a longitudinal direction, and the dial is disposed inside the upper portion of the container part through which the opening is formed, thereby exposing at least part of the dial to an outside. 
     
     
         5 . The cosmetic container of  claim 4 , further comprising a connection part configured such that a stop protrusion configured to protrude in a circumferential direction and to be seated on an upper end surface of the container part and a coupling portion configured to extend downward from one area of a bottom surface of the stop protrusion and to come into tight contact with and be coupled to an inside of an upper end of the container part are formed and at least part of the transfer tube is inserted into and disposed in the connection part. 
     
     
         6 . The cosmetic container of  claim 5 , wherein a first stepped portion is formed on an outer circumferential surface of a lower portion of the dial in a circumferential direction, a second stepped portion corresponding to the first stepped portion is formed on an inner circumferential surface of an upper portion of the container part, and the first stepped portion is placed on the second stepped portion, thereby enabling the dial to be disposed inside the upper portion of the container part. 
     
     
         7 . The cosmetic container of  claim 6 , wherein an upper end of the dial is supported by a bottom surface of the coupling portion, and a lower end of the dial is supported by the second stepped portion of the container part, thereby preventing the dial from being selectively lifted and lowered. 
     
     
         8 . The cosmetic container of  claim 1 , wherein:
 a guide groove is formed on an inner circumferential surface of the container part, at least one elastic piece configured to be bent inward is formed on an outer circumferential surface of a lower end portion of the dial, and a guide protrusion corresponding to the guide groove protrudes from one area of the elastic piece in an outward direction; and   the guide groove and the guide protrusion are formed such that inclined surfaces and slopes that come into contact with each other according to a rotation direction of the dial are different, so that the dial is guided through rotation in a forward direction and prevented from being rotated in a reverse direction.   
     
     
         9 . The cosmetic container of  claim 8 , wherein the guide groove has first and second inclined surfaces formed in opposite directions, the guide protrusion has third and fourth inclined surfaces formed in opposite directions, and each of the first and third inclined surfaces has a gentler slope than each of the second and fourth inclined surfaces. 
     
     
         10 . The cosmetic container of  claim 9 , wherein:
 when the forward rotation is applied to the dial, the first and third inclined surfaces come into contact with each other, the elastic piece is bent inward, and the dial performs the forward rotation; and   when the reverse rotation is applied to the dial, the second and fourth inclined surfaces come into contact with each other, and the dial is prevented from performing the reverse rotation.   
     
     
         11 . The cosmetic container of  claim 5 , further comprising a discharge unit including:
 a discharge head coupled to the connection part and the transfer tube and configured such that a discharge passage through which the cosmetics are discharged is formed therein; and   a discharge control unit configured to selectively open and close a communication hole through which the cosmetics enter into the discharge head.   
     
     
         12 . The cosmetic container of  claim 11 , wherein:
 the discharge control unit includes an elastic member configured to be supported by a bottom surface of an inside of the discharge head and to exert elastic force downward, and an opening/closing member configured to be pressed by the elastic member downward and to seal the communication hole; and   the opening/closing member opens the communication hole due to discharge pressure of the cosmetics attributable to the rotation of the dial.   
     
     
         13 . The cosmetic container of  claim 11 , further comprising an application part configured such that at least part thereof is accommodated in an upper side of the discharge head and the application part applies cosmetics, discharged through the discharge passage, to a skin of the user.
