ABSTRACT:
A food container consisting of a top and a bottom having obliquely angled side elements is disclosed. The container may be cut from a single blank of container material and formed into a hingedly connected top and bottom. When the top and bottom are open and substantially coplanar the obliquely angled sides permit multiple boxes or containers to be nested within one another for efficient stacking. A preferred embodiment includes tops and bottoms with eight side elements comprising one piece side elements and side elements having overlapping panels. When closed, the top side elements overlap the bottom side elements. The container also includes a locking tongue and opening which receives the tongue. A tab may be provided to assist in moving the tongue to disengage it from the opening.
