ABSTRACT:
A novel structure for use in the microwave cooking of foodstuffs for consumption is described. The structure includes an array of individual shapes of flexible electroconductive material normally opaque to microwave radiation supported on a microwave transparent substrate. Each of the individual discrete shapes of flexible electroconductive material has a thickness normally opaque to microwave radiation and is formed in an H-, I- or elongate strip shape. The individual discrete shapes are arranged on the substrate to define a space surrounding the periphery of each individual shape with the spaces defining a continuous aperture extending throughout the array and effective to generate thermal energy in the continuous aperture when the article is exposed to microwave energy and the foodstuff is in contact with or proximate to the aperture. The multiple layer article of manufacture is adapted to be formed into a packaging structure in which a foodstuff may be heated by microwave energy to an edible condition.
