  • Patent number: 5125391
    Abstract: A heat-retaining food service container includes an outer shell assembly, and an expandable inner container arrangement within which is disposed a mass of heat-fusible material. Attendant to heating of the heat-fusible material to an elevated temperature, the material undergoes a phase change and expansion. The expandable inner container arrangement accommodates such expansion of the fusible material, while avoiding any appreciable deformation of the outer shell assembly. The construction promotes efficient heat-transfer to food within the container.
