PROBLEM TO BE SOLVED: To provide a lid material for a container body containing an instant food cooked by pouring hot water which does not cause leakage of the hot water even when the container during steam cooking is moved.SOLUTION: A lid material having a tab part and sealed onto a container body consists of a laminate composed of an outer lid and an inner lid, laminated through a peelable layer. In the inner lid, a first inner lid cut line, a second inner lid cut line forming a hot water pouring port are formed, and, in the outside of the second inner lid cut line in the opening direction in the inner lid, a third convex inner lid cut line is formed from one end edge of the outer peripheral edge to the other end edge in the opening direction. In the outer lid, a first outer lid cut lines are formed between the second inner lid cut line and the third inner lid cut line in a bilaterally symmetrical form, with a tying part between them, from one end edge of the outer peripheral edge and the other end edge to the convex proximity of the third inner lid cut line in the opening direction. In the outside of the third inner lid cut line in the opening direction, a second convex outer lid cut line is formed from one end edge of the outer peripheral edge to the other end edge in the opening direction. |
