摘要:
Indentation patterns in microwave packaging materials can enhance the baking and browning effects of the microwave packaging materials on food. The indentation patterns can provide venting to either channel moisture from one area of the food product to another, trap moisture in a certain area to prevent it from escaping, or channel the moisture completely away from the food product. The indentation patterns can cause the microwave packaging material underneath a food product to be slightly elevated above the cooking platform in the base of a microwave. The indentation patterns can lessen the heat sinking effect of the cooking platform by providing an air gap for insulation. Elevating the base of the microwave packaging material further allows more incident microwave radiation to propagate underneath the microwave packaging material to be absorbed by the food product or by microwave interactive materials in the microwave packaging material that augment the heating process.
摘要:
An abuse-tolerant microwave food packaging material includes repeated sets of metallic foil or high optical density evaporated material segments disposed on a substrate. Each set of metallic segments is arranged to define a perimeter having a length equal to a predetermined fraction of the operating or effective wavelength of an operating microwave oven. The repeated sets of segments act both as a shield to microwave energy and as focusing elements for microwave energy when used in conjunction with food products, while remaining electrically safe in the absence of the food products.

A microwavable container includes an outer sleeve (12) and an inner tray (14) within the sleeve designed to carry a food product. A first active microwave energy heating element (28) is on the sleeve and disposed opposite the tray. A second active microwave energy heating element (74-102) is within the tray. The second microwave energy heating element has patterns of microwave energy interactive material on the bottom (60) and side walls (62) of the tray configured to permit a controlled degree of penetration of incident microwave energy through the bottom wall to channel microwave energy towards a central region of the tray and to promote browning of a food product carried by the tray about its periphery.
摘要:
One aspect of the present invention is a container that includes a microwave interactive web at least partially overlying and joined to a three-dimensional support, wherein the three-dimensional support may be formed prior to having the microwave interactive web mounted thereto. The three-dimensional support may be a preformed container that is sufficiently rigid and dimensionally stable for use in containing food.
摘要:
A microwave energy interactive structure includes microwave energy interactive material supported on a microwave energy transparent substrate, and a plurality of spaced apart microwave energy transparent segments circumscribed by the microwave energy interactive material. The plurality of spaced apart microwave energy transparent segments define a pattern of loops that may be dimensioned to induce resonance of microwave energy during microwave heating of a food item on the structure. The structure may also include a plurality of microwave energy transparent elements that are operative as fuses to prevent overheating of the structure.
摘要:
A cookware system includes a microwaveable metal collecting pan, configured in a bowl shape with a plurality of elongated slots disposed thereon. The collector pan is positioned in a supporting bowl to catch dripping fluids and to provide a basin to hold water during steam cooking. A food item can be placed inside the pan, which is in turn placed inside the bowl and covered with a lid.
