| 摘要 | A three dimensional structure made of corrugated board that has at least two flat rectangular surfaces that: are not coplanar; are not parallel; share a common straight edge; and each have multiple, parallel, straight flutes inside of the flat rectangular surface that intersect the common straight edge at an angle that is between 30 and 60 degrees. A corrugator machine that has a configuration that produces corrugated board stock having two parallel, spaced apart outside edges and multiple, parallel, straight flutes inside of the corrugated board stock that intersect each of the outside edges at an angle that is between 30 and 60 degrees. | ||||||
