PROBLEM TO BE SOLVED: To prevent dripping of liquid while smooth movement being ensured for opening and closing, and make a pouring tube satisfactorily drained of liquid. SOLUTION: The structure is composed of a cap main body 1, mounted on the mouth of a container main body 3 and equipped with a pouring tube 5 that is erected at its top wall 4, and an upper cap 2 hinged to the cap main body 1, being capable of moving for opening and closing, and equipped with an insert cylinder 7 to be inserted into the pouring tube 5 when being closed. The pouring tube 5 is constituted of a cylindrical tube body 8 erected at the top wall 4 and a flange 9 provided, being projected outward, at the upper end on the outer circumference of the tube body 8, and the flange 9 is formed in a width of 2mm or more. Thereby, liquid can be prevented from being remained on the outer circumferential edge of the flange 9 because of surface tension working on returning liquid on the flange 9. |
