<P>PROBLEM TO BE SOLVED: To provide a lid having a resealed condition maintaining function in which the resealed condition is easily maintained even by a lid without dead holding property while the lid is unsealed, hot water is poured, the lid is resealed, and a food is steam-cooked when an instant food such as a cup noodle is eaten. <P>SOLUTION: The lid (A) having the resealed condition maintaining function has the outline which is substantially same as that of an opening part of a container body (B) and has an unsealing pull-tab (2) on an outer peripheral edge (1). The lid consists of a laminate in which a surface base layer (20) and a plastic film layer (50) are laminated. One or a plurality of rows of half-cut lines (3) for forming the resealed condition maintaining function extending in the direction orthogonal to the unsealing direction are formed in a back surface part except a peripheral edge part to be heat-welded to a flange part (5) of the container body (B) of the lid (A) in a range leading to the surface base layer (20) from the inner surface side of the plastic film layer (50). <P>COPYRIGHT: (C)2007,JPO&INPIT |
