Abstract
A liquid storage bottle includes a bottle main body, a nozzle having a discharge port through which a liquid stored in the bottle main body is discharged, a cap mountable on the nozzle and a sealing unit sealing the discharge port when the cap is mounted on the nozzle. The sealing unit includes an annular first rib, an annular second rib and an annular third rib. The outer peripheral surface of the first rib is inclined with respect to the axial direction of the nozzle so that a diameter decreases toward a tip portion of the first rib and the inner peripheral surface of the third rib is inclined with respect to the axial direction of the cap so that a diameter increases toward a tip portion of the third rib.
