A cook-in carton includes a two-panel wall. The inner one of the two panels is provided with vent openings, and the outer one of the panels extends over the openings and is adhered to the inner panel by tabs on opposed edges thereof. The outer panel includes between the tabs a weakened section and opposed flaps. Parallel score lines are provided in each of the flaps, and lugs are formed on the free edges of the flaps upon removal of the weakened section. The flaps are then foldable, in accordion fashion, followed by insertability of the lugs into apertures aligned therewith, where they are restrained in formation of carton support legs.

In a carton for use in heating a product contained therein, including a plurality of hingedly interconnected panels forming said carton, two of said panels being similarly dimensioned and configured and being secured in face-to-face contact to provide inner and outer panels of a two-panel wall in said carton, a central portion of said inner panel having first openings formed therein to permit substantial exposure of the contained product, the outer of said two panels having two lines of weakness extending completely thereacross for defining a centrally located removable weakened section, said removable section being dimensioned and configured to cover said first openings of said inner panel, a pair of rectilinear first score lines, each first score line extending along an opposite region of said outer panel, one rectilinear first score line on each side of said weakened removable section, each first score line located between one end of said outer panel and one of said lines of weakness, for defining two foldable flaps therebetween, the portions of said outer panel between said flaps and the end of said outer panel comprising tabs secured to said inner panel so that, upon removal of said removable section of said outer panel, said flaps may be folded about said first score lines away from said inner panel, thereby providing support legs on said carton, and disengagement of said removable section from the remainder of said outer panel uncovering said first openings and effecting substantial exposure of the product contained within the carton, the improvement comprising: a second score line on each said flap, extending parallel to each said first score line and located between each said first score line and said line of weakness nearest said first score line; and at least one locking lug extending from the free edge portion of each of said flaps; said inner panel having at least two second openings additional to said first openings, said second openings being formed in said inner panel underlying each said flap and being configured for receiving each said lug therein upon folding said flaps away from said inner panel on said first score lines and back towards said inner panel on said second score lines for positively locking each said flap portion into a triangular folded support position with the base of one side of the triangular support being the portion of said inner panel containing said second openings and with the other two sides of the triangular support forming a channel for directing steam into said second openings in said inner panel. A cook-in carton formed of a suitably cut and scored blank, having top and side walls, and a two-panel bottom wall, said bottom wall including an inner panel having an array of venting openings and an outer panel having a weakened section covering some of said openings, opposed flaps covering the remaining openings adjacent said flaps and adherent to the inner panel to mount the outer panel over the openings, and said flaps being foldable about provided first score lines away from said inner panel upon removal of said weakened section to uncover said openings, in provision of support legs for said carton, wherein the improvement comprises: a second score line in each said flap parallel to said first score line; a pair of lugs formed in each said flap upon removal of said weakened section; and said pair of lugs being insertable into and retained within one pair of said openings aligned therewith, upon folding of each said flap about said first score line and said second score line, away from and then toward said inner panel, thereby providing support legs for said carton.
