PROBLEM TO BE SOLVED: To provide a lid member which has a lamination structure of an inner lid and an outer lid to form a hot water drainer hole on the inner lid by peeling them, and secures excellent peeling, and prevents unintended breakage between inner layers.SOLUTION: A release layer arranged between an inner lid and an outer lid is partitioned into four kinds of areas as first to fourth peeling areas in a descending order of area rates of a release agent. The first peeling area 31 is an area having a lid member center angle of 180° with a knob part 2 placed in a center, and extends along a lid member peripheral edge. The third peeling area 33 extends on an outer side than a hot water drainer hole cut 4 along an inner side of the first peeling area 31 from a first position A to a second position B. The second peeling area 32 is structured of two areas of an area 32a extending from the first position A to an inner lid cut 5 along the first peeling area 31 and the lid member peripheral edge, and an area 32b extending from the second position B to the inner lid cut 5 along the first peeling area 31 and the lid member peripheral edge. A remaining area (except for an inner side of the hot water drainer hole cut 4) is the fourth peeling area 34.SELECTED DRAWING: Figure 3 |
