<P>PROBLEM TO BE SOLVED: To obtain a sealing structure member of a container, wherein a sealing material can be arranged with sufficient thickness between the top part of a pouring port and the top wall of a cap and a cap-integrated structure formed so as to save the sealing material can be resealed. <P>SOLUTION: Before a three-folded wall part forming stage where the three-folded wall consisting of an inner wall, an intermediate wall and an outer wall is formed by compressing a cylindrical shell 20, a reforming stage where a sealing material filling groove 21 is formed in the corner part between a top wall part 7 to be a cap part and the outer wall 6 which is extended from the outer periphery to the axial direction, filling the sealing material 12 is filled in the sealing material filling groove and, after that, the sealing material filling groove is deformed into the original state, is arranged, thereby at least the sealing material 12 is formed so as to have a drooping part which is drooped along the outer wall from the outer peripheral part of the inner surface of the top wall and, and in a pouring port forming stage, the sealing material is surely positioned between a projecting returned part 9 and a stepped part 10, without escaping from there. <P>COPYRIGHT: (C)2007,JPO&INPIT |
