ABSTRACT:
There is provided an improved disposable receptacle with a self-supporting configuration for combined baking and cooking of a generally flat food article, such as pizza having a given thickness, in a microwave oven, which receptacle is constructed from a sheet of microwave susceptor stock surrounding the food article and comprising an outwardly exposed, dielectric support layer, such as paperboard, and an inwardly facing heating layer of microwave interactive material allowing passage of microwave energy as it is heated thereby and further including a lower flat portion for supporting the food article during microwave heating. The improvement in this type of disposable receptacle, which is generally a self-supporting sleeve or box, includes forming the lower flat portion of the sleeve with layer means for absorbing nearly all of the microwave energy passing from the outside of the sleeve through the lower portion so that the microwave energy at the lower portion of the sleeve surrounding the food article is converted into heat to a substantially greater extent than other portions of the sleeve. The lower portion of the food product is, thus, heated primarily by conduction, while the upper portion is heated by combined radiation from the susceptor sheet and microwave absorption through the susceptor sheet and from other extraneous heat sources.
