A liquid cosmetics case comprising: a case body having an opened upper portion and filled with a liquid content therein; a solder unit coupled to the opened upper portion of the case body and having a discharge tube in which a discharge hole is defined in a central portion thereof; a valve unit inserted into the discharge tube to open or close the discharge hole according to the elevation of a valve nozzle of the valve unit; a valve actuator unit rotatably coupled to an upper portion of the solder unit to convert the rotation movement into a vertical linear movement of the valve nozzle and open or close the discharge hole; and an applicator unit (600, 800) coupled to an upper end of the valve actuator unit to discharge the content discharged by the rotation of the valve actuator unit through a plurality of fine discharge holes (631, 812); characterized in that when the valve nozzle descends by the rotation, the valve actuator unit opens the discharge hole to discharge the content, and when the valve nozzle ascends, the valve actuator unit closes the discharge hole to block the discharge of the content; and the valve unit comprises: a valve housing extending in a circular tube shape with an opened upper portion and integrated with an inner lower portion of the discharge tube and having a lower end communicating with the discharge hole; wherein the valve nozzle is installed vertically movable by passing through the discharge hole in a state of being inserted into the valve housing, having a nozzle hole therein and an inflow hole, which is connected to the nozzle hole to introduce the content into the nozzle hole, in a side thereof; and a switching member movably fitted outside the valve nozzle, wherein, when the valve nozzle moves toward the discharge hole, the switching member is pushed to a side opposite to the discharge hole by a pressure of the content introduced between the valve housing and the valve nozzle, and when the valve nozzle moves toward a side opposite to the discharge hole, the switching member is pushed by the valve nozzle to return its original state. a case body having an opened upper portion and filled with a liquid content therein;
