Liquid cosmetic case

Abstract

A liquid cosmetic case configured to allow liquid contents to be discharged through opening/closing a valve nozzle according to a rotation. The liquid cosmetic case includes: a body configured such that liquid contents are discharged through a discharging hole; a container inserted into the body through a lower end opening portion of the body in a slidable manner and in which the liquid contents are filled; a container cap coupled to an upper end of the container; a valve unit connected to a discharging side of the body and the container cap to open/close the discharging hole and provided with an opening/closing member slided in association with the container and the container cap; and a rotary elevator part coupled to the lower end of the body, connected to a lower end of the container and thereby vertically moving the container when being rotated.

What is claimed is: 
     
         1 . A liquid cosmetic case comprising:
 a body configured such that liquid contents are discharged through a discharging hole;   a container which is inserted into the body through a lower end opening portion of the body in a slidable manner and in which the liquid contents are filled;   a container cap coupled to an upper end of the container;   a valve unit connected to a discharging side of the body and the container cap to open/close the discharging hole and provided with an opening/closing member slided in association with the container and the container cap; and   a rotary elevator part coupled to the lower end of the body, connected to a lower end of the container and thereby vertically moving the container when being rotated,   wherein when the rotary elevator part is rotated to move the container upwardly, the opening/closing member opens a moving passage of the contents and the contents are thereby discharged, and when the container is downwardly moved, the opening/closing member closes the moving passage of the contents and the contents are thereby prevented from being discharged.   
     
     
         2 . The liquid cosmetic case of  claim 1 , wherein the body has a rotary coupling groove formed in an annular shape in a lower end of an inner side surface of the body, and the rotary elevator part has a rotary coupling protrusion inserted and coupled into the rotary coupling groove and formed in an annular shape, wherein the rotary elevator part is coupled to the body in a rotatable manner. 
     
     
         3 . The liquid cosmetic case of  claim 1 , wherein the rotary elevator part is configured to have a circular tube shape having an opened upper portion, and a lower portion of the container is inserted and coupled into the rotary elevator part through the opened portion of the rotary elevator part. 
     
     
         4 . The liquid cosmetic case of  claim 3 , wherein the container comprises a cam part in which a plurality of inclining teeth are formed on a lower end of an outer side surface in a circumferential direction thereof at regular intervals, and the rotary elevator part comprises a plurality of cam protrusions formed on a lower end of an inner circumferential surface thereof so as to correspond to the inclining teeth, wherein when the rotary elevator part is rotated, the container is moved up and down as the cam protrusions move the cam part in an up-and-down direction through inclining contact with the inclining teeth. 
     
     
         5 . The liquid cosmetic case of  claim 4 , wherein the inclining teeth are formed in a triangular shape having a downwardly inclining surface and a vertical surface with respect to a rotating direction of the rotary elevator part, wherein when the rotary elevator part is rotated in one direction, the container is slided toward the discharging hole as the cam protrusions contact the downwardly inclining surface to thereby upwardly move the cam part, and the container is slided toward an opposite side to the discharging hole as the cam protrusions pass the inclining surface and is positioned in parallel with the vertical surface to thereby downwardly move the cam part. 
     
     
         6 . The liquid cosmetic case of  claim 4 , wherein the inclining teeth are formed in a triangular shape having a downwardly inclining surface and an upwardly inclining surface with respect to the rotating direction of the rotary elevator part, wherein when the rotary elevator part is rotated in both directions, the container is slided toward the discharging hole as the cam protrusions contact the downwardly inclining surface to thereby upwardly move the cam part, and the container is slided toward an opposite side to the discharging hole as the cam protrusions pass the downwardly inclining surface and contact the upwardly inclining surface to thereby downwardly move the cam part. 
     
     
         7 . The liquid cosmetic case of  claim 1 , wherein the valve unit comprises:
 a valve nozzle installed to pass through the container cap in a vertically movable manner, having a nozzle hole formed therein and connected to the discharging hole, and having an introducing hole formed in a side portion thereof and connected to the nozzle hole so as to allow the contents to be introduced in the nozzle hole;   a sliding member inserted and coupled into the outer side of the valve nozzle and slided toward the discharging hole by being pushed by the container cap when the container and the container cap are slided toward the discharging hole; an elastic member installed to elastically support the sliding member against the discharging hole side and returning the sliding member to an original state when force pushing the container and the container cap is released; and   an opening/closing member coupled to an outer side of the valve nozzle in a movable manner, opening the introducing hole by being pushed toward the discharging hole by a pressure of the contents introduced between the container cap and the valve nozzle when the sliding member is slided toward the discharging hole, and closing the introducing hole while being returned to the original state by being pushed by the sliding member when the sliding member is returned to the original state.
