A lower periphery on a back surface of the valve is supported by a seating portion of a container mouth or a seating portion of a joint that is supported by the container mouth, and the container cap has an anchor for anchoring an insertion member to the cap by using a peripheral edge forming a fitting hole in the cover, while inserting the insertion member into the insertion hole.
