摘要： A food container lid member (10) of a construction in which a surface sheet (11) is laminated on a composite sheet (1), the lid member (10) including an easily peelable region (A) containing an easily peelable layer (5) formed by applying a release agent between the composite sheet (1) and the surface sheet (11), an opening region (C) disposed in the easily peelable region (A) and having a hot water discharge port formed therein, and a nonpeelable region (B) disposed adjacent the easily peelable region (A), the food container lid member further including a first cut (7) made in the direction of the vertical section of the composite sheet (1) to form a hot water discharge port, and a second cut (9) made in the direction of the vertical section of the surface sheet (11) to separate the surface sheet in the easily peelable region (A). Further, the lid member (10) is a food container lid member wherein in the hot water discharge port formed by the first cut (7), the composite sheet (1) and the surface sheet (11) are bonded at a smaller area than that of the hot water discharge port without a release agent applied therebetween.
