Patent ID: 8198571

Claim:
A microwave heating construct, comprising: a plurality of compartments defined by a single sheet of microwave energy interactive insulating material, the microwave energy interactive insulating material including a layer of microwave energy interactive material supported on a first polymer film layer, and a second polymer film layer that at least partially defines a plurality of expandable insulating cells that inflate upon exposure to microwave energy, wherein the single sheet of microwave energy interactive insulating material comprises a first section, a second section, and a third section, each having substantially equal dimensions, the second section being disposed between the first section and the third section, the first section and the second section at least partially define a first compartment of the plurality of compartments, the first section and the third section at least partially define a second compartment of the plurality of compartments, and the first section, second section, and third section are joined along at least one respective edge.
