<P>PROBLEM TO BE SOLVED: To provide a spout stopper which can be firmly and surely fixed to a container, even when the container is a paper product, and which can be attached to an optional position of the paper container. <P>SOLUTION: An insert portion 5 of the spout stopper A is plunged into a top face portion B-1 of the paper container B to cut the top face portion B-1 by knife portions of three inserting parts 12, whereby three broken pieces are formed at the top face portion B-1. The broken pieces are pushed out to form an insert opening, and the spout stopper is then twisted, whereby base portions of the broken pieces are fitted into wedge-shaped clearances formed by edge portions continued to the knife portions and a plug portion while contacting with the edge portions to fix and attach the spout stopper A to the paper container B. <P>COPYRIGHT: (C)2013,JPO&INPIT |
