PURPOSE: To enhance sealability when a cap main body is fixed to a mouth cylindrical part by a fitting means. CONSTITUTION: A weighing cup 20 is inserted in the mouth cylindrical part 13 of a container main body 10 and the outer peripheral surface of the large diameter part of the weighing cup 20 is closely fitted to the inner peripheral surface of the leading end part of the mouth cylindrical part 13. The attaching cylindrical part 41 of a cap main body 40 is externally fitted to the mouth cylindrical part 13 and the upper cylindrical part of the weighing cup 20 and the engaging ridge 46 of the attaching cylindrical part 41 is engaged with the lower side of the engaging ridge 14 of the mouth cylindrical part 13 to fix the cap main body 40 to the container main body 10. At this time, the inner peripheral surface of the upper cylindrical part 23 of the weighing cup 20 is closely fitted to the outer peripheral surface of the seal cylindrical part 45 of the cap main body 40. The engaging ridge of the attaching cylindrical part 41 is engaged with the flange part 22 of the weighing cup 20 to prevent the detachment of the weighing cup 20 from the cap main body 40. When a cover cap 60 is closed, a first closing cylindrical part 64 is closely fitted to the leading end of an overflow pipe part 25 to close an overflow hole 31 and a second closing cylindrical part 65 is closely fitted to the inside of a pouring port 50 to close the pouring port 50. |
