Abstract
Various blanks and constructs formed therefrom are provided. The various constructs include features for supporting a food item at an elevated position to enhance the heating, browning, and/or crisping of the food item in a microwave oven.
Claims58
A microwave heating construct, comprising:
- a platform;
- a layer of microwave energy interactive material overlying at least a portion of the platform;
- a pair of side panels extending substantially downwardly from a first pair of opposed edges of the platform along respective first fold lines extending in a first direction, each side panel of the pair of side panels including a pair of substantially vertical lines of disruption defining at least a portion of an adjustable wall portion between a respective first fold line and a respective peripheral edge of the side panel opposite the respective first fold line, wherein the adjustable wall portion is adapted to be transformed into a wall for the platform by tearing along the vertical lines of disruption in the side panels and rotating the adjustable wall portion upwardly along the respective first fold line;
- and
- a pair of end panels extending substantially downwardly from a second pair of opposed edges of the platform along respective second fold lines extending in a second direction substantially perpendicular to the first direction.

A microwave heating construct, comprising:
- a platform including
- a central portion having a first dimension extending in a first direction and a second dimension extending in a second direction substantially perpendicular to the first direction, and
- a pair of end portions at opposite ends of the central portion, each end portion having a first dimension extending in the first direction and a second dimension extending in the second direction, the second dimension of each end portion being greater than the second dimension of the central portion;
- a plurality of support elements extending downwardly from each end portion of the platform;
- a pair of adjustable side walls, each adjustable side wall of the pair of adjustable side walls including
- a proximal panel hingedly joined to the central portion of the platform along a first fold line extending in the first direction, and
- a distal panel hingedly joined to the proximal panel along a second fold line extending in the first direction;
- and
- a layer of microwave energy interactive material overlying at least a portion of the platform and each adjustable side wall.
6 more elements
A blank for forming a construct, comprising:
- a plurality of adjoined panels, each having a first dimension extending in a longitudinal direction and a second dimension extending in a transverse direction substantially perpendicular to the first direction, the plurality of panels including
- a main panel,
- a pair of substantially opposed side panels foldably joined to the main panel along respective substantially opposed longitudinal fold lines, and
- a pair of substantially opposed end panels foldably joined to the main panel along respective substantially opposed transverse fold lines;
- and
- a pair of substantially opposed side portions adapted to be at least partially separated from a remainder of the blank, each side portion of the pair of side portions being defined by
- a pair of substantially opposed transverse tear lines extending substantially across the respective side panel into the main panel, and
- a longitudinal line of disruption extending between the respective pair of substantially opposed transverse tear lines.
5 more elements
A microwave heating construct for a food item, comprising:
- a platform comprising microwave energy interactive material;
- a pair of side panels extending substantially downwardly from a first pair of opposed edges of the platform along respective first fold lines extending in a first direction;
- and
- a pair of end panels extending substantially downwardly from a second pair of opposed edges of the platform along respective second fold lines extending in a second direction substantially perpendicular to the first direction,
- wherein the side panels each include an adjustable wall portion defined at least partially by
- a pair of substantially vertical lines of disruption between the respective first fold line and a respective peripheral edge of the side panel opposite the first fold line,
- a pair of tear lines extending in the second direction from the respective first fold line into the platform, the pair of tear lines being substantially aligned with the pair of vertical lines of disruption in the respective side panel, and
- a line of disruption extending in the first direction substantially between endpoints of the respective pair of tear lines extending from the respective first fold line into the platform,
- wherein the respective first fold line divides the adjustable wall portion into
- a proximal section disposed between the respective line of disruption extending in the first direction and the respective first fold line, and
- a distal section disposed between the respective first fold line and the respective peripheral edge of the adjustable wall portion,
- wherein the adjustable wall portions are each operative for being transformed into a wall for the platform by
- tearing along the vertical lines of disruption in the respective side panel and along the respective tear lines extending into the platform, and
- rotating at least one of the proximal section and distal section of the adjustable wall portion upwardly along at least one of the respective first fold line and the respective line of disruption extending in the first direction.

A microwave heating construct, comprising:
- a platform comprising microwave energy interactive material;
- a pair of side panels extending substantially downwardly from a first pair of opposed edges of the platform along respective first fold lines extending in a first direction, each side panel of the pair of side panels including a pair of substantially vertical lines of disruption defining at least a portion of an adjustable wall portion between the respective first fold line and a respective peripheral edge of the side panel opposite the first fold line;
- a pair of end flaps foldably joined to respective opposite ends of each side panel of the pair of side panels along respective oblique fold lines;
- and
- a pair of end panels extending substantially downwardly from a second pair of opposed edges of the platform along respective second fold lines extending in a second direction substantially perpendicular to the first direction.
