Abstract
A food heating package for elongated products such as french fries and fish sticks which includes partitions formed from microwave energy absorbing material adapted to crisp, toast or brown the surfaces of the foods sticks. The partitions preferably enclose the food sticks on at least three sides and can be made by forming folds in a sheet of vapor-deposited semiconductive metallic coating applied to a plastic film, e.g. polyester, backing.
Claims12
A package for heating food sticks comprising:
- a microwave transparent package enclosure;
- at least one food heating susceptor formed from microwave receptive sheet material within said package;
- said susceptor including a plurality of parallel folds therein extending within the susceptor sheet to divide the package into a plurality of side-by-side locations each sized to hold at least one of said food sticks that is to be heated by conduction from the microwave receptive sheet material;
- each of the side-by-side locations holding a food stick such that the folded microwave receptive sheet material is in face to face relationship with a surface of each food stick;
- the food sticks in the locations being oriented with respect to one another in a predetermined manner such that the longitudinal axis of each stick is parallel to those of the other sticks and also coincides with the axis of each location in the susceptor sheet to facilitate the transfer of heat from the susceptor sheet to each stick so as to brown, crisp or toast the surface thereof during heating in a microwave oven.

A package for heating food sticks comprising:
- a microwave transparent package enclosure;
- said enclosure including first and second broad opposing faces, relatively narrow connecting walls extending between the broad opposing faces;
- at least one microwave receptive susceptor sheet within the package and extending therein generally parallel to the broad opposing faces;
- said microwave receptive susceptor sheet including a plurality of parallel side-by-side folds to provide food holding locations between the parallel folds to receive the food sticks;
- each of the locations between the folds being sized to hold at least one of the food sticks that is to be heated by conduction from the microwave receptive sheet material;
- each of the locations holding a food stick such that the microwave receptive sheet material is in face-to-face relationship with a surface of the food stick;
- the food sticks being oriented with respect to one another in a predetermined manner such that the longitudinal axis of each food stick is parallel to those of the other food sticks and also coincides with the axis of each location of the sheet holding the food stick to facilitate the transfer of heat from the susceptor to each food stick so as to brown, crisp or toast the surface thereof.
