Microwave cooking container cover

Claim 1

A cover for a container having at least one compartment for prepared foodstuff for reconstitution for consumption by microwave energy, which consists essentially of: a planar continuous polymeric material layer, a microwave-reflective pattern supported on and in adhered relation with one surface of said polymeric material layer comprising a continuous layer of microwave reflective material within a periphery thereof, said microwave reflecting material inhibiting the flow of a microwave energy through the cover within the periphery of and in the location of said pattern on said polymeric material layer and enhancing the flow of microwave energy through said cover outside the periphery of said pattern and in the region of said polymeric material layer from which said continuous layer of microwave reflective material is absent whereby there is controlled the degree to which prepared foodstuff positioned in the at least one compartment is subjected to microwave energy through said cover when the container is exposed to microwave energy, and a layer of paperboard material coextensive in dimension with said flexible polymeric material layer and adhered to said polymeric material layer outside said periphery of said pattern and to said pattern within said periphery, so as to sandwich said layer of microwave-reflective material between said polymeric film layer and said paperboard material layer.
