Abstract
An improved microwave energy moderating cooking bag for enclosing, for instance, a food stuff such as a beef roast so that it can be cooked at a relatively high, constant level of power in a microwave energy field (eg; in a microwave oven) to a predetermined degree of doneness without needing to periodically reposition the roast to achieve uniform doneness. The improved bag is of the type having microwave enery moderating wall portions which comprise perforated electrically conductive sheet material: for example, aluminum foil. The bag is improved by virtue of having adjacent side-by-side segments of the perimetrical edges of the electrically conductive sheet material sufficiently offset with respect to each other to virtually obviate edge-to-edge electric field relations. That is, sufficiently offset to precipitate edge-to-surface electric field relations as opposed to edge-to-edge electric field relations.
