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.

A microwave heating construct comprises a base, a wall extending upwardly around the base for defining a cavity for receiving a food item, and a microwave energy shielding element overlying a lower margin of the wall, the microwave energy shielding element having an upper edge including a substantially incurved portion.

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 container 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.

A construct for heating a food item in a microwave oven includes a base, a wall extending upwardly from the base, a microwave energy shielding element overlying at least a portion of the wall, and a microwave energy diffusing element circumscribed by the microwave energy shielding element. The microwave energy diffusing element includes a plurality of microwave energy reflective elements within a microwave energy transparent area.

A susceptor structure includes a layer of conductive material supported on a non-conductive substrate. The conductive layer includes a resonant loop defined by a plurality of microwave energy transparent segments and, optionally, a microwave energy transparent element within the resonant loop.
摘要:
A container has a patterned susceptor region in the bottom, a fold region between the bottom and the sidewall of the container, a sidewall region, and a flange region that forms a flange or lip of the container. The patterned susceptor region includes arrangements of microwave-interactive features disposed generally along respective close plane curves, which reduces overheating and increases the filling temperature of the food product. The fold region contains microwave transparent features that minimize de-lamination of the container in the folded region, and also create a generally transmissive area in the vicinity of the heel of the food product to improve the cooking thereof. The sidewall region shields the periphery of the food product so that it is not overcooked while promoting an appropriate degree of pie dough shell browning. The flange area is transmissive to promote an appropriate degree of cooking of the food product crust.
