PROBLEM TO BE SOLVED: To provide a lid member with a hot-water drain hole, which allows hot-water drain holes to be simply formed, is simple to manufacture and is excellent in sealability.SOLUTION: The lid member has a form including an unsealing tab and a hot-water drain hole forming tab protruding outward at opposite positions along an outer periphery, comprises an outer lid and an inner lid stacked by an adhesive resin layer via a peeling means, and is put on an opening of a container by a lid heat-bonding region for use. An outer lid cut line coupling between both circumferential rims of the hot-water drain hole forming tab is formed on the outer lid. A region surrounded by the hot-water drain hole forming tab and the outer lid cut line is to serve as a hot-water drain hole forming region. The peeling means is formed to be opposite at least to the hot-water drain hole forming region. A hot-water drain hole cut passing through the inner lid and the adhesive resin layer is formed on the hot-water drain hole forming region. A hot-water drain hole forming cut line passing through the inner lid and the adhesive resin layer is formed to extend over the lid heat-bonding region inside the hot-water drain hole forming tab. |
