Claims
- 1. A package for heating food sticks comprising, a microwave transparent package enclosure, a plurality of parallel partitions formed from microwave receptive sheet material extending within the package to divide the package into a plurality of side-by-side chambers each sized to hold at least one of said food sticks to be heated by conduction from the microwave receptive sheet material, each of the chambers enclosing a food stick such that the microwave receptive sheet material is in face to face relationship with the surfaces of each food stick, the food sticks 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 chamber to facilitate the transfer of heat from each chamber to each stick so as to brown, crisp or toast the surface thereof.
- 2. The package of claim 1 wherein the microwave interactive sheet comprises a tray formed from said sheet by being folded into a plurality of parallel upright flutes that are pressed as by pinching the sheet into narrow folds defining said flutes, said flutes being spaced apart from one another and extending parallel to one another, each of the flutes comprising a double thickness of said sheet to provide a fluted tray in which the compartments are defined by the spaces between the flutes and each food stick is deposited in one of the compartments and is surrounded on three sides thereby.
- 3. The package of claim 2 wherein the package enclosure is a paper or paperboard carton.

- 9. A package for heating food in a microwave oven comprising, a carton having telescoping upper and lower parts adapted to contain a multiplicity of food sticks arranged in substantially parallel relationship, chambers formed from flexible sheet material enclosed within the carton, a food stick in each of the chambers and the food sticks being oriented such that the longitudinal axis of the food sticks coincide with the axis of the chamber, at least a portion of each of the chambers having a microwave interactive susceptor material therein for transferring heat to an adjacent surface of one of the food sticks to toast, brown or crisp the food stick.
- 10. A microwave heating package including a carton formed from microwave transparent sheet material having a top portion and a bottom portion, a multiplicity of elongated french fried potato pieces within the carton, each piece being parallel to all of the other pieces within the carton and each of the french fried potato pieces being at least partially surrounded by a microwave interactive susceptor sheet said sheet being formed to provide parallel chambers having walls in contact or almost in contact with each piece, said chambers each having a longitudinal axis and being open at one end of the carton, said carton having a closing wall normally obstructing the open ends of the chambers and said closing wall being removable from said open ends whereby when said closing wall is removed the french fried potato pieces can slide out of the package through the ends of the chambers.
- 11. The package of claim 10 wherein the microwave interactive sheet comprises a tray formed from said sheet by being folded into a plurality of parallel upright flutes that are pressed as by pinching the sheet into narrow folds defining said flutes, said flutes being spaced apart from one another and extending parallel to one another, each of the flutes comprising a double thickness of said sheet to provide a fluted tray in which the chambers are defined by the spaces between the flutes and each potato piece is deposited in one of the chambers and is surrounded on three sides thereby.
- 12. A package for heating food sticks comprising:
- a microwave transparent package enclosure;
- said enclosure comprising a carton including first and second broad opposing faces, relatively narrow connecting sidewalls extending between the broad face walls, at least one microwave receptive sheet extending within the package between the sidewalls and in generally parallel relationship to the broad face walls;
- said microwave receptive sheet including a plurality of side-by-side chambers including microwave receptive partitions therebetween to provide walls for the chambers;
- said partitions extending between the broad faces of the carton and generally perpendicular thereto;
- each of the chambers between the partitions being sized to hold at least one of the food sticks to be heated by conduction from the microwave receptive sheet material;
- each of the chambers enclosing a food stick such that the microwave receptive sheet material is in face-to-face relationship with the 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 of the chambers to facilitate the transfer of heat from the walls of each chamber to each food stick so as to brown, crisp or toast the surface thereof.
- 13. The package of claim 12 wherein a portion of the enclosure comprises a removable portion adapted to expose the food sticks for allowing their removal from the package enclosure.
- 14. The package of claim 13 wherein the cover portion of said package enclosure is connected to a remaining portion of the package by means of a severable member that can be torn or otherwise disconnected to allow the cover to be removed from said remaining portion of the package enclosure.

- both the partitions and the floor portion of each of the chambers including said microwave interactive material so as to brown, crisp or toast more than one side of the food pieces.
- 18. The package of claim 17 wherein the sheet comprises paper or plastic film having a layer of a microwave interactive material applied to at least one surface thereof.
- 19. The package of claim 18 wherein the microwave interactive material comprises a semiconductive metallic coating that is deposited by metallization of the sheet.
