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.

[ I claim:] [1.] A blank for a non-rectangular box having an improved non-sloping double-panel wall structure, said blank being cut and scored to define:(a) a bottom panel;(b) a first double-panel wall structure comprising:(i) a first outer panel hingedly attached at a first outer panel bottom edge

[ I claim:] [1.] A blank for a non-rectangular box having an improved non-sloping double-panel wall structure, said blank being cut and scored to define:(a) a bottom panel;(b) a first double-panel wall structure comprising:(i) a first outer panel hingedly attached at a first outer panel bottom edge to said bottom panel and having a predetermined shape, said first outer panel bottom edge having first and second ends,(ii) a first inner panel hingedly linked to a top edge of said first outer panel at a first fold line and having a predetermined shape,(iii) a first interlock portion disposed along an outer edge of said inner panel;(c) a first interlock receptor means disposed adjacent said first outer panel bottom edge, whereby after said blank has been erected into a carton said first interlock portion engages with said first interlock receptor means, thereby causing said first inner panel to be disposed approximately parallel to said first outer panel and forming a first double-panel wall;wherein:said first outer panel bottom edge is disposed at an oblique angle to a bottom edge of at least one adjacent wall panel;said first interlock receptor means is disposed substantially closer to the first end than to the second end of said first outer panel bottom edge;the predetermined shape of said first inner panel is substantially different from the predetermined shape of said first outer panel;said first fold line is parallel to said first outer panel bottom edge, whereby after said blank has been erected into said carton said first double-panel wall is substantially non-sloping, thereby resulting in a non-rectangular box having an improved non-sloping double-panel wall.
