Carton with vent opening arrangement

A one-piece carton blank of foldable sheet material formable into an enclosed container, said container being suitable to retain consumable contents therein containing liquids so that said consumable contents can be (1) heated in an oven while retained therein and (2) thereafter consumed while retained therein, said carton blank is cut and scored such that said carton blank includes:

• a bottom wall panel having a periphery defined by four interconnecting side fold lines interrelated so that there are four different pairs of adjacent side fold lines wherein each adjacent side fold line of a pair of adjacent side fold lines extends at an angle with respect to each other from a corner point defining one of four corners of said bottom wall panel;
• four side wall panels integral with said bottom wall panel along said side fold lines and interrelated so that there are a first pair of opposed side wall panels, a front side wall panel, and a rear side wall panel, said side wall panels being foldable along said side fold lines in a uniform direction relative to said bottom wall panel to form compartment sides;
• an integral connection between adjacent side wall panels, said integral connection being foldable and sealable to form leak tight sealed integral corners;
• and
• a lid wall panel integral with said rear side wall panel along a lid fold line, said lid wall panel being foldable along said lid fold line in a direction inward toward said bottom wall panel so that in a closed position said lid wall panel encloses a container space defined by said bottom wall panel and said four side wall panels wherein said consumable contents are contained,
• said lid wall panel having cuts therein defining a vent access section operable to be manually removed from said lid wall panel along a predetermined vent separation path in response to a manual venting procedure so as to expose a vent access opening to an interior of said container space, said vent access section including a grippable portion extending from an edge of said lid wall panel operable to be gripped as an initial step in said manual venting procedure,
• said lid wall panel having cuts therein defining an eating access section operable to be manually separated along a predetermined eating access separation path in response to a predetermined manual eating access opening procedure so as to enable said eating access section to be manually moved to an access position during said manual eating access operating procedure, the exposure of said vent access opening exposing a portion of said eating access section communicating therewith operable to be gripped as an initial step in said manual eating access operating procedure.
