Abstract:

A ripple bottom pizza box and the method of creating a pizza box with such a ripple bottom. A pizza box blank is provided that is made of corrugated cardboard. The corrugated cardboard has parallel corrugation waves that traverse a flat bottom section pf the pizza box blank in a first direction. A roller is provided that has multiple parallel roller heads. The flat bottom section of the pizza box blank is advanced under the rollers. The parallel roller heads press parallel depressions into the flat bottom section in a direction perpendicular to the first direction of the corrugation waves. The result is that when the pizza box blank is folded into a pizza box, the bottom of the pizza box is contoured with parallel depression lines.
