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.
Claims4
In a pizza box blank made of corrugated cardboard and having a flat bottom section, wherein said corrugated cardboard has parallel corrugation waves, disposed between a top layer and a bottom layer, that traverse said flat bottom section in a first direction, a method of forming depressions in said flat bottom section, comprising the steps of:
- providing a roller having multiple parallel roller heads;
- and
- advancing said flat bottom section of said pizza box blank under said roller, wherein said parallel roller heads compress said corrugation waves flat between said top layer and said bottom layer, therein producing parallel depressions in said flat bottom section of said pizza box blank in a direction perpendicular to said first direction of said corrugation waves.
