<P>PROBLEM TO BE SOLVED: To provide a combination of a container and a container lid whose required unsealing torque and tentative sealing torque are appropriately valued for releasing the seal of the neck part of the container after a break line is broken in opening the sealing of the neck part. <P>SOLUTION: In forming this combination of the container and the container lid, the outer peripheral faces 18, 118 of the curl parts 4, 104 of neck parts 2, 102 have the maximum outer diameter positions 20, 120 on their top end and the outer diameter gradually decreases downward at least partially. In a condition where the lid 22 is mounted on the neck part, the inner diameter of the inner peripheral face 56a of an annular sealing protrusive strip 56 gradually decreases downward at least partially from a tight contact position contacting the maximum outer diameter position of the curl part. A gap 62 is maintained between the skirt wall 30 of a shell 24 and the outer peripheral face 56b of the strip, and the bottom face 56c of the strip inclines downward and outward in the radius direction. <P>COPYRIGHT: (C)2009,JPO&INPIT |
