Abstract
A paperboard container for use in a microwave oven to cook an expandable food has a square bottom support panel, upwardly and outwardly tapering, concave, trapezoidal side panels connected to each edge of the bottom support panel, and a cover of overlapped, top panels. A top panel is foldably connected to an upper arcuate edge of each of the side panels and a seal is removably attached to one of the top panels and an opposed one thereof to close the container. Upon expansion of the food within the container in a microwave oven, the concave side panels will expand to aid in confining the food within the perimeter of the container.
