The pouring cylinder 74 of the pouring member 6 extends radially outward beyond the outer periphery of the plug 4. Further, the protruding wall portion 65 formed on the ventilation cover portion 60 of the plug 4 is picked up with a finger and pulled upward to break the breakable score 62 formed on the ventilation protruding portion 58, thereby breaking the vent hole break portion. 63 is removed. Thus, a ventilation hole 88 is formed at the upper end of the ventilation projection 58 as shown in FIG. Thereafter, when the container is tilted in a direction in which the pouring tube portion 74 of the pouring member 6 is inclined downward toward the tip, the discharge port 86 formed in the discharge cover portion 42 and the pouring tube of the pouring member 6 are discharged. The liquid contained in the container is discharged via the section 74. At this time, the outside air enters the container from the ventilation hole 88 formed in the ventilation protrusion 58, and the smooth discharge of the liquid through the discharge cylinder 74 is promoted.

After the required amount of liquid has been discharged, the spouting member 6 is rotated clockwise as viewed from above in FIG. 3 so as to be in the closed position shown in FIGS. In this closed position, the top wall 68 of the pouring member 6
Is pressed against the upper surface of the annular wall portion 44 of the discharge covering portion 42, and thus the discharge port 86 is closed. Pouring cylinder part 74 of pouring member 6
Extends on the top wall 18 of the plug 4 without extending outward beyond the plug 4. Further, the breakable portion 63 for the ventilation hole removed by breaking the breakable score 62 of the ventilation protruding portion 58 is turned upside down, and the gripping piece 66 is grasped with a finger to insert the protruding wall portion 65 into the ventilation hole 88. At least, the ventilation hole 88 is closed. When both the outlet 86 and the ventilation hole 88 are closed in this way, the mouth and neck portion 80 is closed again, and leakage of the liquid is sufficiently and reliably prevented. Further, the outer lid 2 is attached to the mouth and neck portion 80. When the liquid in the container is discharged again, the discharging member 6 is positioned at the discharging position shown in FIG.
It is sufficient to remove the broken portion 63 for the ventilation hole inserted in the hole and open the ventilation hole 88 again.
