PROBLEM TO BE SOLVED: To provide a spout stopper facilitating cap removal, facilitating finger hooking to a pull ring, and capable of preventing a form of the pull ring from being warped without increasing height.SOLUTION: A spout stopper includes a plastic cap and a spout. The spout includes: a cylindrical sidewall formed with first and second screw threads to screw the cap; a partition wall for closing the inside of the spout; a pull ring for uncapping connected to the partition wall and at least partially protruding from the sidewall; and a flange connected to the sidewall and welded to an edge inner face of a mounting hole in a packaging container. On each of the first and second screw threads, a full thread part which is an effective part which can be screwed with an internal thread formed in the cap has length defining a central angle of at least 180° and not more than 270° around a central axis of the sidewall ranging from a start position to an end position.SELECTED DRAWING: Figure 2
