PURPOSE: To perfectly stop a liquid by eliminating the backlash to an inner plug by constituting a liquid pouring container so that the short cylinder of an outer cap is pressed to the top surface of a nozzle support, the side surface of the outer cap is pressed to the opening end of a nozzle when the outer cap is screwed and the shoulder part of the outer cap and the end edge of the flange part of the inner plug are fixed in a close contact state. CONSTITUTION: The inclined surface of an outer cap 30 is processed so as to come into close contact with the leading end part of a nozzle 22 when the outer cap 30 is fitted to a container main body 10. The shoulder part 32 coming into contact with the flange part 23 of an inner plug 20 is provided to the outer cap 30 below the dome-shaped top surface of the cap and a short cylinder 31 for fixing a nozzle support 21 is provided to the inside of the top surface. When the outer cap 30 is closed, the leading end of the nozzle 22 comes into close contact with the inner surface of the outer cap 30 to prevent the leakage of a washing soln. Even if there is backlash between male and female screws 13, 33, the outer cap 30 is not deflected and can be reasonably fitted to the container main body 10. |
