The combination of insulating material with microwave interactive food packaging for enhanced cooking properties is disclosed. An insulating microwave packaging material (200) and a method of making the same are also disclosed. In one embodiment, the insulating microwave packaging material (200) is formed by bonding a microwave interactive material substrate (205) that creates sensible heat upon exposure to microwave energy to a second substrate (210) along bond lines (212) arranged in a pattern to form closed cells (214). Upon impingement of the insulating microwave packaging material (200) by microwave energy in a microwave oven, the closed cells (214) expand to form insulating pockets (216). One side of the insulating pocket (216) bulges and lofts above the opposite side. When a food product is situated on the insulating microwave packaging material (200), the insulating pockets (216) insulate the food product from the microwave oven environment.

Insulating microwave interactive packaging

A tray (100) or container (478) which may be hermetically sealed having a flange encapsulated by or formed from injection-mold material. The tray (100) has a flange (116) extending outwardly from a sidewall (114) of the tray, and containing irregularities induced by the creation of the tray (100). An encapsulating material surrounds the flange (116) in substantially uniformly thick manner, and along with the flange (116) defines an encapsulated rim (124). The encapsulating material is generally a plastic such as polyolefin, nylon, or polyethylene, but may also be made from other materials. This encapsulating material covers a portion of the flange (116) and extends a set distance from the flange's (116) outer edge.

Container having a rim or other feature encapsulated by or formed from injection-molded material

A container (30) has a patterned susceptor region (22) in the bottom, a sidewall region (26), a fold region (24) between the bottom region and the sidewall region, and a flange region (28) that forms a flange container (30). The patterned susceptor region (22) 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 (24) contains microwave transparent features that minimize de-lamination of the container (30) in the fold region (24) 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 (26) 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 region (28) is transmissive to promote an appropriate degree of cooking of the food product crust.

Patterned microwave susceptor element and microwave container incorporating same

Various constructs that absorb exudates and optionally enhance browning and crisping of a food item during heating in a microwave oven are provided.

Absorbent microwave interactive packaging

An apparatus for decoding an audio signal and method thereof are disclosed. The present invention includes receiving the audio signal and spatial information, identifying a type of modified spatial information, generating the modified spatial information using the spatial information, and decoding the audio signal using the modified spatial information, wherein the type of the modified spatial information includes at least one of partial spatial information, combined spatial information and expanded spatial information. Accordingly, an audio signal can be decoded into a configuration different from a configuration decided by an encoding apparatus. Even if the number of speakers is smaller or greater than that of multi-channels before execution of downmixing, it is able to generate output channels having the number equal to that of the speakers from a downmix audio signal.

Method and apparatus for decoding an audio signal

The heating effect of a microwave susceptor can be improved by providing a pattern of microwave transparent areas in the susceptor. The transparent areas are preferably circles having a diameter of about 0.5 inch. The distance between adjacent circles is preferably about 0.5 inch. The susceptor may be used to brown and crispen the crust of frozen pizza heated in a microwave oven. The crust of the pizza is browner, especially at its central area, than the crust of pizza heated using a conventional susceptor.

Patterned microwave susceptor

A package configured to receive a food item for storage and heating therein is disclosed. The package includes an opening and a closure mechanism and comprises heat insulating, microwave energy interactive material. A plurality of packages in a stacked relation is also provided.

Microwave Interactive Flexible Packaging

A package for heating a food item comprises a sleeve including a thermal insulating material having at least one void occupied by an insulating gas. Another package comprises a sleeve and an insulating shell. Still another package comprises a construct including at least one arcuate end panel, a susceptor material, and an insulating material. Blanks for forming such packages and others also are disclosed.
