Liquid dropper allowing quantitative withdrawal, and a cosmetic container equipped with the same

Abstract

The present invention relates to a liquid dropper allowing quantitative withdrawal and discharge, comprising a liquid-dropper tube formed with an annular projecting part around the outer circumferential rim at the upper end, a lid which is joined to the upper end of the liquid-dropper tube and is formed with a through hole in the center, a liquid-dropper piston which is formed with a press pin at the lower end and is inserted inside the liquid-dropper tube and which passes through the through hole, a button which is provided joined to the upper end of the liquid-dropper piston, and packing which is provided on the lower part of the annular discharge part of the liquid-dropper tube and is formed with a projecting part around a lower outer circumferential rim; and to a cosmetic container equipped with the same.

1 - 4 . (canceled) 
     
     
         5 . A liquid dropper allowing quantitative withdrawal, comprising:
 a liquid dropper tube an upper side and a lower side of which are open for an engagement of the liquid dropper piston and for content to be sucked, with a gasket being engaged to the opened upper side;   a lid which is engaged to an upper side of the liquid dropper tube and has a through hole at its center and an engaging protrusion at both sides of a lower outer surface;   a liquid dropper piston which has a plunger tip at its lower end and is inserted into the interior of the liquid dropper tube and passes though the through hole; and   a button which is engaged at an upper side of the liquid dropper piston.   
     
     
         6 . The liquid dropper of  claim 5 , wherein an inner diameter of a lower end of the liquid dropper tube decreases, and a projecting part engaged to the lid is formed at an upper outer surface, and an engaging groove corresponding to the projecting part is formed at an inner surface of the lid. 
     
     
         7 . A cosmetic container with a liquid dropper allowing quantitative withdrawal of  claim 5 , comprising:
 a container which has a function storing content and has a concave part at a portion coming into contact with the plunger tip at an inner lower end and has an engaging part at its upper side; and   an inner cap ‘which is detachably formed at the engaging part and has a through hole formed at its center for the liquid dropper to detachably insert and has a fixing piece corresponding to the engaging protrusion at an inner surface for an engagement as the engaging protrusion rotates in one direction.   
     
     
         8 . The container of  claim 7 , further comprising:
 a wiper which is inserted into an inner surface of the engaging part and is made from an elastic material in such a way that an inner diameter corresponding to an outer diameter of the liquid dropper tube gradually decreased in its downward direction and has a plurality of spaced-apart support protrusions at its inner surface for the purpose of supporting the liquid dropper tube and has an air hole at its lower side for air to flow.   
     
     
         9 . A cosmetic container with a liquid dropper allowing quantitative withdrawal of  claim 6 , comprising:
 a container which has a function storing content and has a concave part at a portion coming into contact with the plunger tip at an inner lower end and has an engaging part at its upper side; and   an inner cap ‘which is detachably formed at the engaging part and has a through hole formed at its center for the liquid dropper to detachably insert and has a fixing piece corresponding to the engaging protrusion at an inner surface for an engagement as the engaging protrusion rotates in one direction.
