Food container lid member having selectively peelable area

A lid member for a food container having substantially the same circumference as that of an opening of a container body in a food container and having a layered structure in which a base layer and a surface sheet are laminated through an adhesive layer, wherein the lid member comprises:

• an easily-peelable area of the layered structure having a lubricant between the base layer and the surface sheet, a non-peelable opening area of the layered structure disposed within the easily-peelable area;
• a non-peelable area of the layered structure disposed adjacent to the easily-peelable area, said lid member further comprising:
• a first tab to peel off the lid member from the container body,
• a second tab formed on the easily-peelable area along a boundary line between the non-peelable area and the easily-peelable area to form the apertures of the opening area,
• a first slit, cut from the base layer to the adhesive layer forming the apertures in the opening area,
• a second slit, cut from the surface sheet to the adhesive layer, along the boundary line between the easily-peelable area and the non-peelable area disposed adjacent to the easily peelable area, and
• a third slit, cut from the base layer to the adhesive layer and disposed where the second tab is mounted, at a foot-end of the second tab, and extending from a spaced from the second slit, to a cross position with the second slit.
