Abstract

A food carton is disclosed in the general shape of a tapered tray which includes an integral overlapping top cover portion, an integral divider element and an easy opening tear strip. In its preferred form, the carton is prepared from a one piece blank of paperboard or the like with either glued or interlocked ends located between two tapered side walls. The top flaps of the carton at least partially overlap one another with one top flap having integral therewith the carton divider element and the other top flap including the tear strip opening means. Each of the side and end walls of the carton are preferably perforated with apertures or the like to enhance the flow of air around the packaged food product and preserve its freshness.

(e) a pair of end walls foldably attached to opposite ends of said bottom panel;

(f) a top closure supporting flap foldably attached to each end closure flap at the end opposite said bottom panel, and further including a notch located substantially at the midpoint thereof for accepting and capturing the integral carton divider element when it is folded into position to divide the carton;
