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.
Claims50
A construct for heating, browning, and/or crisping a food item in a microwave oven, comprising:
- a platform for receiving the food item, the platform including a microwave energy interactive element;
- and
- a pair of opposed support elements joined to the platform along respective fold lines, wherein
- each fold line joining the respective support element to the platform is interrupted by a receiving slot substantially centered along the fold line, and
- each support element includes a locking feature dimensioned to be received within the respective receiving slot, the locking feature extending upwardly through the receiving slot such that a portion of the locking feature is positioned above the platform.

A construct for heating, browning, and/or crisping a food item in a microwave oven, comprising:
- a platform for receiving the food item, the platform including a microwave energy interactive element;
- and
- a pair of opposed support elements joined to the platform along respective fold lines, each support element including
- a first panel extending substantially downwardly from the platform,
- a second panel foldably joined to the first panel, the second panel being substantially parallel to the platform, and
- a third panel foldably joined to the second panel, the third panel extending substantially upwardly towards the platform,
- wherein
- each fold line joining the respective support element to the platform is interrupted by a receiving slot substantially centered along the fold line, and
- each support element includes a locking feature dimensioned to be received within the respective receiving slot.
6 more elements
A construct for heating, browning, and/or crisping a food item in a microwave oven, comprising:
- a platform having an upper surface defined at least partially by a susceptor film;
- a pair of support elements extending downwardly from the platform;
- and
- a locking feature extending upwardly from each support element through a slit disposed between the platform and the respective support element, wherein
- each support element comprises a plurality of foldably joined panels, and
- at least one panel of the plurality of foldably joined panels is disposed beneath the platform.

A construct for heating, browning, and/or crisping a food item in a microwave oven, comprising:
- a platform having an upper surface defined at least partially by a susceptor film;
- a pair of support elements extending downwardly from the platform, each support element including
- a first panel extending substantially downwardly from the platform,
- a second panel joined to the first panel, the second panel defining a lowermost portion of the respective support element, and
- a third panel joined to the second panel, the third panel extending obliquely and upwardly towards the platform;
- and
- a locking feature extending upwardly from each support element through a slit disposed between the platform and the respective support element.
4 more elements
A construct for heating, browning, and/or crisping a food item in a microwave oven, comprising:
- a platform having a first dimension extending in a first direction and a second dimension extending in a second direction, the platform including a microwave energy interactive element;
- and
- a pair of opposed leg portions joined to the platform along respective fold lines extending in the first direction, each leg portion including
- a first panel extending downwardly from the platform,
- a second panel joined to the first panel, the second panel being substantially parallel to the platform, and
- a third panel extending from the second panel towards the platform.
3 more elements
A construct for heating, browning, and/or crisping a food item in a microwave oven, comprising:
- a platform comprising a microwave energy interactive element and a plurality of apertures;
- and
- a pair of opposed support elements joined to the platform along a pair of opposed edges of the platform, each support element including
- a center panel foldably joined to the platform, and
- a pair of end panels foldably joined to the center panel so that the end panels are disposed beneath the platform,
- wherein each end panel includes a locking feature adapted to extend upwardly through an aperture in the platform, the aperture being distal from the pair of opposed edges of the platform.
3 more elements
A construct for heating, browning, and/or crisping a food item in a microwave oven, comprising:
- a platform including a microwave energy interactive element, and
- a pair of side support elements, each support element including
- a central panel extending downwardly from a side edge of the platform, the side edge extending between a first end and a second end of the platform, and
- a pair of end panels foldably joined to each central panel beneath the platform, each pair of end panels including a first end panel proximate the first end of the platform and a second end panel proximate the second end of the platform,
- wherein
- the respective first end panels are adapted to engage one another, and
- the respective second end panels are adapted to engage one another.
4 more elements
A construct for heating, browning, and/or crisping a food item in a microwave oven, comprising:
- a platform including a microwave energy interactive element;
- and
- a pair of support elements adapted to maintain the platform in an elevated position, the pair of support elements including a first support element and a second support element,
- wherein
- the first support element includes a first panel extending downwardly from the platform, a second panel joined to the first panel, the second panel being substantially parallel to the platform, and a locking feature, and
- the second support element includes a first panel extending downwardly from the platform, a second panel joined to the first panel, the second panel being substantially parallel to the platform, and third panel joined to the second panel along a fold line, wherein the fold line is interrupted by a slit dimensioned to receive the locking feature.
