A liquid cosmetic case in which a supporting cap (31) to which a brush is (30) fixed is fixed to the upper side of a tube-shaped container (1) that stores liquid cosmetic and is coupled with a discharger (10) closed after discharging liquid cosmetic and a cap (40) is thread-coupled with the upper side of the tube-shaped container (1) so that the discharger (10) coupled with the supporting cap (31) ascends and descends by opening and closing the cap (40). When the cap (40) ascends, a ring-shaped step (5) in the upper end of a liquid supplying container (6) is opened so that a through hole (12) and a liquid guiding passage (11) formed by an inner protrusion wheel step (7) are connected to a discharge hole (12) and that the liquid cosmetic in the tube-shaped container (1) is discharged to the brush (30). When the cap (40) descends, the ring-shaped step (5) in the upper end of the liquid supplying container (6) is pressed and closed so that the liquid cosmetic stored in the tube-shaped container (1) does not leak and that a user can safely carry the liquid cosmetic case.
