An improved heat retaining foodservice system including a heat retaining food cover (10), food container (310) and underbase (210), each including a heat storage system comprised of a sealed chamber therewithin, said chamber containing a layer of non-metallic heat storing material, such as micro crystalline wax enclosed by a layer of film for keeping food warmer for longer periods of time. Preferably, the food cover, container and underbase are each constructed of high-temperature stable polymeric material which is transparent to microwave radiation to f...
A heat retaining food container comprising: (a) a wall means defining a container for food, said wall means being transparent to microwave energy, said wall means defining a first sealed chamber; (b) at least one sealed second chamber within said first chamber; said second chamber being at least partially defined by flexible thin wall film, said wall means completely enclosing said second chamber; and (c) a heat storing mass contained within said second chamber, said mass comprising a fusible material which may be heated using microwave radiation, said m...
