<p>PROBLEM TO BE SOLVED: To enable direct holding of the external face of a container with one's bare hand after the contents have been heated in a microwave oven, by sticking a heat-insulation sheet on the outer periphery of the cup container. SOLUTION: A heat-insulation sheet B constituted of a heat-insulative sheet 11 and an adhesive layer 21 laminated on the rear face of the heat-insulative sheet 11 is stuck on the outside face of the peripheral side face 1 of a cup container A. The heat-insulative sheet 11 is formed of a single raw material sheet 12. Non-woven cloth made by mixing of natural fiber and synthetic fiber chiefly composed of natural fiber, non-woven cloth made by mixing of synthetic fiber and natural fiber chiefly composed of synthetic fiber, or porous foam sheet made by foaming of synthetic resin, is used. Since the heat-insulation sheet containing air, provided with a porous non-woven cloth or a foam layer is stuck on the outer peripheral face of such a container, a heat-insulation effect is brought out and the structure makes it possible to directly hold the container with one's bare hand and take it out even immediately after it has been heated in a microwave oven.</p> |
