<p>PROBLEM TO BE SOLVED: To provide a container in which an opening start position of interlayer peeling can be easily formed.SOLUTION: While a center of a heat seal part 23 is displaced with respect to a center of an opening 24A, and the heat seal part 23 intersects a part of an outer peripheral edge of a flange part 25, a lid body 3 is pressed against the flange part 25 and attached thereto by a seal board. By a simple attachment method which relatively displaces with respect to the flange part 25 by using the conventional seal board, an opening start position where the heat seal part 23 is positioned at the outer peripheral edge of the flange part 25 can be formed easily, and sealing workability can be improved.</p> |
