PROBLEM TO BE SOLVED: To provide a paper tray excellent in display effect and also functioning as a heat insulating cover for preventing a burn. SOLUTION: Ridge panels 3 of which the central parts expand and side panels 4 of which the skirts become narrow are successively connected to the respective sides formed into an arcuate shape of the peripheral edge of a quadrilateral top panel 2 having a container insertion part 1 and successively bent downward with respect to the top panel 2 and a bottom surface is closed by a bottom panel 6. The central parts of four sides of the top panel 2 are throttled by the inward curving of the ridge panels 3 and built up convexly and a cup container C is effectively emphasized. Further, excellent design effect is developed because the side panels 4 become narrow downward. The heat of the heated food in the cup container C is cut off to prevent a burn.
