Abstract
Abstract A microwavable package for browning the surface of a plurality of small food articles is disclosed. The package is disposable and includes an outer carton in which a microwave susceptor is housed. The susceptor is a unitary device which includes a plurality of compartments therein. Each compartment is sized to house a single food product and maintain physical contact between the susceptor means and a substantial portion of the food product. Upon heating in a microwave oven the physically-contacted portion of the surface of food product is browned or crisped to produce an aesthetically pleasing food.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
A microwavable package for food products which imparts a brown or crisp texture to a substantial portion of the food product surface upon exposure to microwave energy comprising: a microwavable housing for enclosing at least one food product; and a single unitary microwave susceptor housed within said housing and being configured to form a plurality of U-shaped channels therein, each U-shaped channel being formed by a plurality of folds in said single unitary microwave susceptor, said folds forming double-layered walls defining said U-shaped channels, wherein the height of said folds is sufficient to enclose and physically contact a substantial portion of the surface of at least one unit of food product such that upon exposure to microwave energy a substantial portion of the surface of the food product becomes crisp or brown.
Claim 2
Dependent Claim
132 words
A microwavable package for food products which imparts a brown or crisp texture to a substantial portion of the food product surface upon exposure to microwave energy comprising: a microwavable housing for enclosing at least one food product; and a single unitary microwave susceptor housed within said housing and being configured to form a plurality of U-shaped channels therein, each U-shaped channel being formed by a plurality of folds in said single unitary microwave susceptor, said folds forming double-layered walls defining said U-shaped channels, wherein the height of said folds is sufficient to enclose and physically contact a substantial portion of the surface of at least one unit of food product such that upon exposure to microwave energy a substantial portion of the surface of the food product becomes crisp or brown.
Claim 3
Dependent Claim
34 words
A package as claimed in claim 1 wherein said susceptor means may also include a cover sheet comprised of a first layer of susceptor material and a second layer of any suitable microwavable material.
Claim 4
Dependent Claim
28 words
A package as claimed in claim 2 wherein said microwave susceptor comprises a material which is at least semi-rigid in order to maintain the integrity of the package.
Claim 5
Dependent Claim
33 words
A package as claimed in claim 3 wherein said microwave susceptor comprises a rigid material which maintains the integrity of said channels to thereby prevent physical deformation of the food product contained therein.
Claim 6
Dependent Claim
31 words
A package as claimed in claim 2 wherein said microwave susceptor comprises a resilient material which allows removal of the food product from said channels without damage to the food product.
