<P>PROBLEM TO BE SOLVED: To provide a sealing method for sealing a neck part of a container by using a container lid consisting of a thin metal plate shell and a synthetic resin packing, which is capable of enhancing the impact resistance, and preventing the sealing from being damaged even if a considerably large impact is applied to a shoulder area of the shell. <P>SOLUTION: In the sealing method, after a container lid is fitted on the neck part, an outer area 60 located on the outer side in the radial direction of the outer peripheral surface at the upper end of the neck part on a top wall 8 of a shell is deformed downward, and at the same time, an inner area 62 located on the inner side in the radial direction of the inner peripheral surface at the upper end of the neck part on the top wall of the shell is also deformed downward. <P>COPYRIGHT: (C)2007,JPO&INPIT |
