Abstract
A paperboard container for use in a microwave oven to cook an expandable food has an octagonal bottom support panel, upwardly and outwardly extending trapezoidal side panels connected to each edge of the bottom support panel, and a pop-up cover of overlapped, semi-ovoid top panels. A top panel is foldably connected to an edge of each of the side panels and a circular seal is removably attached to one of the top panels and an opposed one thereof to close the container. Upon removal of the seal, the top panels assume a substantially upright position as extensions of the side panels to enclose and support, along with the bottom support panel and side panels, an expanded food package.
