ABSTRACT:
A container made of a single-faced paperboard blank formed a corrugated paperboard layer and a substantially flat paperboard layer has scored lines or cuts which define a bottom portion, a cover, a cover support and four side walls. The boundaries of the side walls are defined by a plurality of substantially parallel score and slits that meet at a plurality of points so as to form side walls which have generally triangular ends. The container has four external vents for moisture to pass from the interior of the container to the outside, and three internal vents to allow moisture to pass from the interior of the container to the space between the corrugated and flat paperboard layers.
