Abstract
A microwave heating construct includes a platform having a plurality of peripheral edges, a plurality of elevating panels for maintaining the platform in a raised position, and a layer of microwave energy interactive material overlying at least a portion of the platform. The platform includes a movable portion defined at least partially by a line of disruption extending substantially between a pair of adjacent edges of the platform. The movable portion of the platform is adapted to pivot along the line of disruption.
Claims56
A microwave heating construct, comprising:
- a platform including microwave energy interactive material, the microwave energy interactive material being operative for converting microwave energy into thermal energy;
- and
- a plurality of elevating panels joined to the platform,
- wherein the platform includes a movable portion defined at least partially by
- a first line of disruption extending substantially between a pair of adjacent peripheral edges of the platform,
- a second line of disruption extending between the pair of adjacent peripheral edges of the platform, and
- lines of disruption extending between respective endpoints of the first line of disruption and the second line of disruption along the respective peripheral edge of the platform,
- wherein the movable portion of the platform is operative for pivoting along the first line of disruption.
A microwave heating construct, comprising:
- a platform including microwave energy interactive material, the microwave energy interactive material being operative for converting microwave energy into thermal energy, wherein the platform includes a movable portion defined at least partially by a line of disruption extending substantially between a pair of adjacent peripheral edges of the platform, wherein the movable portion of the platform is operative for pivoting along the line of disruption;
- and
- a plurality of elevating panels joined to the platform, wherein the plurality of elevating panels includes
- a first pair of elevating panels for extending downwardly from the platform,
- a second pair of elevating panels for extending downwardly from the platform, and
- a central elevating panel for supporting a center of the platform, wherein the central elevating panel extends between the first pair of panels,
- wherein
- the first pair of elevating panels and the central elevating panel have a substantially equal vertical dimension, and
- the second pair of elevating panels have a vertical dimension that is less than the vertical dimension of the first pair of elevating panels and the central elevating panel.
A microwave heating construct, comprising:
- a platform including microwave energy interactive material, wherein the microwave energy interactive material is operative for converting microwave energy into heat;
- and
- a plurality of elevating panels extending downwardly from the platform,
- wherein
- the platform is substantially square in shape, such that the platform includes corners and peripheral edges extending between adjacent pairs of the corners;
- and
- the platform includes movable portions operative for bringing the microwave energy interactive material of the movable portions towards a center of the platform, wherein each movable portion is positioned adjacent to one of the corners of the platform, and wherein each movable portion is defined at least partially by
- a first line of disruption extending substantially between a pair of adjacent peripheral edges of the platform,
- a second line of disruption extending between the pair of adjacent peripheral edges of the platform, wherein the second line of disruption is substantially parallel to the first line of disruption, and
- a pair of lines of disruption extending between respective endpoints of the first line of disruption and the second line of disruption along the respective peripheral edge of the platform.
A microwave heating construct, comprising:
- a platform including microwave energy interactive material, the microwave energy interactive material being operative for converting microwave energy into heat, wherein the platform includes a plurality of movable portions for bringing the microwave energy interactive material of the movable portions towards a center of the platform, each movable portion being defined at least partially by
- a first line of disruption extending substantially between a pair of adjacent peripheral edges of the platform,
- a second line of disruption extending between the pair of adjacent peripheral edges of the platform, wherein the second line of disruption is substantially parallel to the first line of disruption, and
- a pair of lines of disruption extending between respective endpoints of the first line of disruption and the second line of disruption along the respective peripheral edge of the platform;
- and
- a plurality of elevating panels extending downwardly from the platform, the plurality of elevating panels including
- a first pair of elevating panels opposite one another,
- a second pair of elevating panels opposite one another, and
- a central elevating panel extending between the first pair of elevating panels, wherein
- the first pair of elevating panels and the central elevating panel are substantially equal in height, and
- the second pair of elevating panels have a height that is less than the height of the first pair of elevating panels and the central elevating panel.
A microwave heating construct, comprising:
- a platform including microwave energy interactive material, the microwave energy interactive material being operative for converting microwave energy into heat, wherein the platform includes a movable portion defined at least partially by a line of disruption extending substantially between a pair of adjacent peripheral edges of the platform, wherein the movable portion of the platform is operative for pivoting along the line of disruption;
- and
- a plurality of support panels foldably joined to the platform, the plurality of support panels including
- a first pair of support panels opposite one another,
- a second pair of support panels opposite one another, and
- a central support panel extending between the first pair of elevating panels,
- wherein
- in a first configuration, the first pair of support panels and the second pair of support panels extend upwardly from the base and central support panel is in a flattened configuration adjacent to the platform, so that the first pair of support panels and the second pair of support panels define an interior space for receiving a food item, and
- in a second configuration, the first pair of support panels, second pair of support panels, and central support panel extend downwardly from the base, wherein the first pair of elevating panels and the central elevating panel are substantially equal in height, and the second pair of elevating panels have a height that is less than the height of the first pair of elevating panels and the central elevating panel.
