Abstract

A microwave heating construct includes a first side wall and a second side wall opposite one another and a food-supporting panel extending between the first side wall and the second side wall. The first side wall includes a movable portion for being positioned over the food-supporting panel. The food-supporting panel and/or the movable portion of the first side wall may include microwave energy interactive material.

Claims (41)

1. A microwave heating construct, comprising:

a first side wall and a second side wall opposite one another; and

a food-supporting panel extending between the first side wall and the second side wall, the first side wall including at least one line of disruption that defines a movable portion of the first side wall, wherein

the movable portion of the first side wall is for being separated along the at least one line of disruption and positioned over the food-supporting panel, and

the food-supporting panel and the movable portion of the first side wall each include microwave energy interactive material; and

the food-supporting panel is joined to the first side wall and the second side wall along a respective first line of disruption and second line of disruption extending in a first direction, the food-supporting panel extends downwardly from the first line of disruption and second line of disruption.

2. The microwave heating construct of claim 1 , further comprising a projection extending inwardly from an upper edge of the second side wall, the projection being for engaging the movable portion of the first side wall when the movable portion of the first panel is positioned over the food-supporting panel.

3. The microwave heating construct of claim 2 , wherein the projection is a first projection of a plurality of projections extending inwardly from the upper edge of the second side wall.

4. The microwave heating construct of claim 1 , wherein

the first side wall and the second side wall each have an upper edge and a lower edge,

the first line of disruption lies along the upper edge of the first side wall, and

the second line of disruption lies along the upper edge of the second side wall.

5. The microwave heating construct of claim 4 , wherein the food-supporting panel includes a lowermost point that is at a higher elevation than the lower edge of the first side wall and the second side wall.

6. The microwave heating construct of claim 1 , further comprising a void beneath the food-supporting panel.

7. The microwave heating construct of claim 1 , wherein the food-supporting panel includes a line of disruption extending along a length of the food-supporting panel.

8. The microwave heating construct of claim 1 , further comprising a pair of end walls joined to respective ends of the first side wall and second side wall, the end walls comprising microwave energy interactive material.

9. A method of preparing a food item in a microwave oven using the microwave heating construct of claim 1 , the food item having an upper surface and a lower surface that are each desirably heated, comprising:

with the food item seated on the food supporting panel, positioning the movable portion of the first side wall over the food item; and

exposing the food item in the microwave heating construct to microwave energy, so that

the microwave energy interactive material of the food-supporting panel heats the lower surface of the food item, and

the microwave energy interactive material of the movable portion of the first side wall heats the upper surface of the food item.

10. The method of claim 9 , wherein

reconfiguring the microwave heating construct further comprises separating the movable portion along the at least one line of disruption before positioning the movable portion of the first side wall over the food item.

11. The method of claim 9 , wherein

the microwave heating construct further comprises a projection extending from the second side wall, and

the method further comprises engaging the movable portion of the first side wall with the projection.

12. The method of claim 9 , wherein

positioning the movable portion of the first side wall over the interior space comprises folding the movable portion of the first side wall along the first line of disruption joining the food-supporting panel to the first side wall.

13. A microwave heating construct, comprising:

a first side wall and a second side wall opposite one another; and

a food-supporting panel extending between the first side wall and the second side wall, the first side wall including at least one line of disruption that defines a movable portion of the first side wall, wherein

the movable portion of the first side wall is for being separated along the at least one line of disruption and positioned over the food-supporting panel, and

the food-supporting panel and the movable portion of the first side wall each include microwave energy interactive material; and

wherein the food-supporting panel includes a plurality of lines of disruption extending in a lengthwise direction along the food-supporting panel, so that the food-supporting panel has a generally U-shape.

14. A blank for a microwave heating construct, the blank comprising:

a plurality of adjoined panels, each panel having a first dimension extending in a first direction and a second dimension extending in a second direction, the first direction being substantially perpendicular to the second direction, the plurality of adjoined panels including

a first panel including a plurality of lines of disruption extending in the second direction substantially across the first panel, and

a second panel and a third panel joined to opposite edges of the first panel along respective first and second fold lines extending in the second direction, wherein the first panel includes at least one line of disruption extending substantially in the first direction substantially from the first fold line to a peripheral edge of the second panel extending in the second direction, the at least one line of disruption defining a movable portion of the second panel,

wherein the first panel and the movable portion of the second panel each include microwave energy interactive material, and the first panel includes an arcuate cut proximate to the second fold line, and the arcuate cut extends inwardly substantially from the second fold line.

15. The blank of claim 14 , wherein the at least one line of disruption extending substantially in the first direction substantially from the first fold line to the peripheral edge of the second panel comprises a pair of tear lines extending substantially in the first direction substantially from the first fold line to the peripheral edge of the second panel.

16. The blank of claim 14 , wherein the arcuate cut is a first arcuate cut of a pair of arcuate cuts proximate to the second fold line, wherein the arcuate cuts each have a pair of endpoints disposed substantially along the second fold line.
