What is claimed is: 
     
         1 . An eco-friendly cosmetic dropper comprising:
 a cap unit including an inner cap coupled to a container body and an outer cap coupled to the inner cap; and   a pumping unit coupled to the cap unit and pumping out and discharging the cosmetic liquid stored in the container body to a pipette unit connected to the cap unit,   wherein the pumping unit includes a wall body disposed in the cap unit to move up and down, a pumping cap configured to move up and down with the wall body and having a piston member coupled thereto, and an elastic member disposed in the cap unit and configured to elastically support the pumping cap;   the elastic member is made of a material containing metal; and   the pumping cap is detachably coupled to the wall body, so the elastic member can be separated out of the wall body.   
     
     
         2 . The eco-friendly cosmetic dropper of  claim 1 , wherein the pumping cap is detachably thread-fastened to the wall body. 
     
     
         3 . The eco-friendly cosmetic dropper of  claim 1 , wherein the pumping cap is detachably locked to the wall body. 
     
     
         4 . The eco-friendly cosmetic dropper of  claim 3 , wherein a coupling protrusion is formed at the pumping cap, and a groove is formed at the wall body, so the coupling protrusion is detachably locked in the groove. 
     
     
         5 . The eco-friendly cosmetic dropper of  claim 1 , wherein the pumping cap includes:
 a base body having a wall portion detachably coupled to an inner wall of the wall body;   a guide post formed on a bottom of the base body, inserted between an inner post and an outer post of the inner cap, and configured to guide up-down movement of the base body; and   a piston coupling post formed on the bottom of the base body at a predetermined distance from the guide post and having the piston member coupled thereto.   
     
     
         6 . The eco-friendly cosmetic dropper of  claim 5 , wherein a first thread is formed on the wall body, and
 a second thread that is thread-fastened to the first thread is formed on the wall portion, so the pumping cap is detachably thread-fastened to the wall body.   
     
     
         7 . The eco-friendly cosmetic dropper of  claim 1 , wherein the pipette unit includes:
 a pipette coupling body having a horizontal body disposed in an inner post and a vertical body formed downward on a bottom of the horizontal body; and   a pipette member coupled to the horizontal body, and   a pipette supporting post supporting an outer wall of the pipette member is formed on an inner cap body of the inner cap.   
     
     
         8 . The eco-friendly cosmetic dropper of  claim 1 , wherein the elastic member is made of stainless steel.
