<P>PROBLEM TO BE SOLVED: To provide a spout stopper and a method of manufacturing a spout stopper in which an opening blade and a fractured sealing film are securely held so as not to drop them into a container, by which a safe spout stopper is obtained, and the spout stopper is easily opened. <P>SOLUTION: The spout stopper provided at a spout hole of the container which is sealed by a sealing film, includes: a spout 7 consisting of a spout cylinder 5 and a base part 6; a cap covering the spout 7; and an opening blade 9 vertically moving in helical form n association with the cap. A first locking fin is provided in the cap. A threadedly engaging section 7a for vertically and helically moving the cap at its opening/closing time, in an inner peripheral face of the cap and an outer circumferential face of the spout cylinder 5 of the spout 7. The opening blade 9 includes: a cylindrical section 10 with a threadedly engaging section 9a, in the outer circumferential face, which vertically moves helically interlocking with vertical helical movement of the cap, by screwing the threadedly engaging section provided in an inner peripheral part of the spout cylinder 5 of the spout 7; and a blade 11 provided in a bottom of the cylindrical section 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
