Abstract:
1. A microwave heating apparatus, comprising: a single piece of a laminate, wherein the single piece of the laminate comprises microwave energy interactive material supported on a polymer film, the microwave energy interactive material being operative for heating in response to microwave energy; a portion of the single piece of the laminate being a press-formed integral tray of the apparatus; another portion of the single piece of the laminate being a press-formed integral cover of the apparatus; and the press-formed integral tray and the press-formed integral cover being foldably joined to one another along a line of disruption in the single piece of the laminate, wherein the press-formed integral tray includes a base and a peripheral wall that define an interior space of the press-formed integral tray, the wall extends upwardly from a periphery of the base, the upwardly extending wall extends around the interior space, an upper surface of the base comprises a plurality of heating areas and a plurality of downwardly extending press-formed channels disposed between the heating areas, a lower, exterior surface of the base comprises a plurality downwardly extending press-formed protrusions, the press-formed protrusions being respectively vertically aligned with the press-formed channels, the heating areas are elevated relative to the press-formed channels, and the heating areas each include the microwave energy interactive material.
