ABSTRACT:
A carton is provided having opposite side portions which project beyond the lower surface of carton. The lower surface is provided with apertures so that heat may pass through the apertures when the carton is placed in an oven or other heating chamber. A strip of film is secured to the lower surface and along an adjoining wall. The film normally closes the apertures, but is removable to expose the apertures.
