ABSTRACT:
A foldable carton for various products which is particularly suitable for storing, microwave cooking and serving of food products. The carton is formed from a one-piece paperboard sheet having a polygonal bottom panel, plurality of side and end panels foldably joined to the edges of the bottom panel and extending completely around the periphery of the bottom panel. Side web assemblies foldably join the side and end panels together in a continuous band and include fold lines positioned to elevate the side and end panels with respect to the bottom to provide a liquid impervious tray. The carton further includes extension panels foldably joined to an outer periphery of the side and end panels, together with extension web assemblies that also form a continuous band completely encircling the outer periphery of the side and end panels. Relief openings are provided in the carton between the side web assemblies and the extension web assemblies in order to permit folding of the extension web panels to and from a vertical position and a position parallel to the bottom panel. The carton further preferably includes a top panel assembly which can be removed by the user to permit the extension panels to be popped up as a unit to provide a mixing and spatter shield, as well as to provide access to the contents of the carton. A set-up carton employing the invention also is disclosed.
