<p>PROBLEM TO BE SOLVED: To easily mount a closure and a simplified water purifier on containers respectively having openings of different sizes by using one cap body having plural connecting means capable of being respectively adapted to the openings of various sizes of the containers, and demountably fixing the closure, the water purifier or the like having the water passing and stopping function, on the cap body. SOLUTION: A large cylindrical body 20b is rotated clockwise. Then a small cylindrical body 30b is rotated to be mounted on the opening of the container in accompany with the rotation of the large cylindrical body 20b as the small cylindrical body 30b is connected to the large cylindrical body 20 by means of a polygonal ring. Here, as the cap body 10b and a closure joint 50 are fitted and engaged with each other, they can be mutually rotated, and a position of the closure 40 can be easily changed after the cap body 10b is firmly connected to the opening of the container. On the other hand, when a size of the opening of the container is agreed with a size of the large cylindrical body 20b, the large cylindrical body 20b is similarly rotated to be connected to the opening of the container.</p> |
