(54) Heat-insulating container


(57) A heat-insulating food container includes an injection-molded container body (3) having a bottom wall (3b), a circumferential wall (3a) integrally connected to a periphery of the bottom wall (3b) and upwardly extending therefrom for defining an inner space and an upper open end, and vertical ribs (7) vertically extending along the circumferential wall (3a). The circumferential wall (3a) includes circumferential wall parts (9a, 9b, 9c) respectively having different diameters and arranged in such a manner as to form the circumferential wall (3a) with the diameter thereof decreasing in a stepwise manner as it advances downwardly, thereby forming corresponding stepped portions on an exterior surface and an interior surface thereof.
