Abstract

Various constructs are provided for heating a plurality of different food items to their respective desired serving temperatures in a microwave oven in about the same amount of time.

Claims (50)

1. A packaging system for heating a plurality of food items in a microwave oven, the system comprising:

a tray including a first compartment and a second compartment, wherein

the first compartment is adapted to receive a frozen first food item, the first food item being substantially a solid when the first food item is heated to its desired serving temperature,

the first food item has an outer surface that is prone to overdrying when exposed to microwave energy and an inner area that is prone to underheating when exposed to microwave energy, and

the first compartment includes

a microwave energy shielding element positioned to be in a facing relationship with the outer surface of the first food item, and

a microwave energy directing element adapted to direct microwave energy towards the inner area of the first food item; and

a container dimensioned to be seated removably within the second compartment, wherein

the container is adapted to receive a frozen second food item, the second food item being substantially a liquid or a semi-liquid when the second food item is heated to its desired serving temperature,

the second food item is prone to underheating when exposed to microwave energy,

the container includes at least one upstanding wall and a susceptor overlying at least a portion of the upstanding wall, and

the microwave energy shielding element, microwave energy directing element, and the susceptor are configured to heat the first food item and the second food item to their respective desired serving temperatures in about the same amount of time.

2. The system of claim 1 , further comprising an overwrap overlying at least a portion of the first compartment, wherein the overwrap comprises a microwave energy interactive material supported on a polymeric film.

3. The system of claim 1 , wherein

the outer surface of the first food item is intended to be browned and/or crisped, and

the first compartment further includes a susceptor.

4. The system of claim 1 , wherein the first food item is a dough-based food item.

5. The system of claim 1 , wherein the first food item is a sandwich or a breaded food item.

6. The system of claim 1 , wherein the second compartment further comprises a segmented foil.

7. The system of claim 1 , wherein the susceptor circumscribes at least one physical or non-physical aperture.

8. The system of claim 1 , wherein the second food item is a beverage, soup, sauce, or gravy.

9. The system of claim 8 , wherein

the first food item is a sandwich, and

the second food item is a soup.

10. The system of claim 9 , wherein the second compartment further comprises a segmented foil.

11. A system for heating a plurality of frozen food items in a microwave oven, the food items each responding differently to microwave energy and each having a desired serving temperature, the system comprising:

a tray having a plurality of compartments including at least a first compartment and a second compartment;

a first container dimensioned to be received removably within the first compartment, the first container including

a plurality of adjoined, substantially planar faces,

a microwave energy shielding element overlying at least a portion of one face of the plurality of adjoined, substantially planar faces, and

a microwave energy directing element overlying at least a portion of one face of the plurality of adjoined, substantially planar faces,

wherein

the first container is adapted to receive a frozen first food item, the first food item being substantially a solid at the desired serving temperature of the first food item, the first food item having an outer area that is prone to overheating and an inner area that is prone to underheating when exposed to microwave energy,

the microwave energy directing element is adapted to direct microwave energy towards the inner area of the first food item, and

the microwave energy shielding element is adapted to reduce the transmission of microwave energy to at least a portion of the outer area of the first food item; and

a second container dimensioned to be received within the second compartment, the second container including

a wall extending upwardly from a base, and

a susceptor overlying at least a portion of the wall,

wherein the second container is adapted to contain a frozen second food item, the second food item being substantially a liquid or semi-liquid at the desired serving temperature of the second food item, the second food item being prone to underheating when exposed to microwave energy,

wherein the microwave energy shielding element and the susceptor are configured to heat the first food item and the second food item to their respective desired serving temperatures in about the same amount of time.

12. The system of claim 11 , wherein the first container is a flexible sleeve, pouch, or wrap.

13. The system of claim 11 , wherein

the outer surface of the first food item desirably is browned and/or crisped, and

the first container further includes a susceptor.

14. The system of claim 11 , wherein the first food item is a dough-based food item, a breaded food item, or any combination thereof.

15. The system of claim 11 , wherein the first food item is a sandwich or a breaded meat.

16. The system of claim 11 , wherein the first container further includes a susceptor, a segmented foil, or any combination thereof.

17. The system of claim 11 , wherein the second container comprises a rigid or semi-rigid cup.

18. The system of claim 11 , wherein the second container further includes a segmented foil overlying the base.

19. The system of claim 11 , wherein the second food item is a beverage, soup, sauce, or gravy.
