<p>The invention has its object to provide hot insulation during cooking with a poured hot water and eliminate danger of a burn during discharge of hot water by forming a lid (20) of a container, for an instant food, of a foam resin, prevent a print indication on a synthetic resin film (41) integrally laminated to a foam resin sheet (3) from being displaced from a normal position at the time of molding of the lid (20), and enable fine and sharp molding of details of the lid (20). To attain this object, a laminate sheet (30) is hot-plate-molded which comprises the synthetic resin film (41), having a thickness (T2) of 15 to 80 νm, integrally laminated to the foam resin sheet (3) having a thickness (T1) of 0.3 to 0.95 mm. Hot-plate-molding is performed such that a laminate sheet is interposed between a hot plate and a molding die to be softened and closely bonded to the molding die for forming the lid.</p> |
