ABSTRACT:
A pizza box blank having a special double-panel wall structure and a non-centrally-positioned interlock receptor means that allows the inner panel of the double-panel wall structure to be formed into a special shape that, in turn, allows the box blank to be made with less material than would be required if the blank contained a conventional double-panel wall structure and interlock receptor means.
