Abstract
A packaged arrangement (1) contains a tray (4) which is convertible into a heating stand by inversion thereof. The walls of the tray are of a material that is transparent to microwave energy, but a support wall (10) which forms a bottom of the tray and top of the stand is provided with a liner of a microwave interactive layer that is formed of a material capable of converting microwave energy into heat. The tray (4) is configured so as to define a storage space for a predetermined quantity of food and to possess sufficient strength as to be able to support the predetermined quantity of food upon the support wall (10) in the inverted, heating stand condition thereof. A second packaged arrangement (1') comprises a recloseable package body (2') that may be used, at least in part, to form the enclosed air space and stand. In accordance with methods of use, food is removed from the package, at least one of the components of the packaged arrangement is formed into an air space enclosing heating stand, upon the floor of a microwave oven, and the food is placed upon this stand during microwave heating thereof.
