The lid comprises a top plate part for sealing the spout and a cylindrical side wall suspended from a peripheral edge of the top plate part. An inner ring (37) is provided in the top plate part of the lid, a thin wall part (34) is provided in an upper part of the cylindrical side wall, and a ride-over rib (35) is provided at a lower end of the thin wall part. When closing the lid, the tip rib rides over the ride-over rib, and the tip rib of the spout tip and an inner surface of the thin wall part, and an inner peripheral surface of the cylindrical side wall and an outer peripheral surface of the inner ring are brought into contact with each other respectively. |
