ABSTRACT:
A carton erected from a one-piece paperboard carton blank permits a frozen pizza to be heated in a microwave oven while still in the carton. The carton has a bottom panel in contact with the pizza crust, the bottom panel having openings to permit venting of steam vapor during heating and the openings forming cross-straps to support the crust. The openings are sealed by a closure panel prior to heating and portions of the closure panel open like shutters on a window and are used, during heating, to support the carton above the oven shelf.
