PROBLEM TO BE SOLVED: To allow the one-touch detachment of a container main body by one hand without pressing the container main body when using it, by a method where, in a notch made in the peripheral wall of a cap main body, a rotary member comprising a spout engagement part and a peripheral wall is freely rotated by being engaged with the rotary shaft part of the side wall of the notch. SOLUTION: A cap 20 is made in such a way that a rotary member 200 is freely rotatably mounted in the notch 130 of a cap main body 100 by the engagement of the rotary shaft part 141 of the cap main body 100 with the bearing hole 215 of the rotary member 200. By attaching a container main body 10 to the cap 20 and by holing its body 15 in one hand and pulling it to the right, the rotary member 200 rotates round the rotary shaft part 141 of the cap main body 100, and inclines in the direction of the rotation, with the container main body 10 on it. And by pulling it obliquely upward, the spout 11 of the container main body 10 is disengaged from the spout engagement part 220 of the rotary member 200 of the cap, so that the container main body 10 can be detached from the cap 20 easily. |
