Abstract:
A die cut blank, comprising:a planar sheet of material having a central portion;two side portions, one each on opposing sides of the central portion and adapted to fold perpendicular to the central portion along a side fold line interposed between each side and the central portion;four tabs, one each extending along a length of each side and from an opposing end of each side, the tabs adapted to fold perpendicular to the side along a tab fold line interposed between each tab and the adjacent side;two crushed areas, one each located at opposing ends of the central portion and between the sides, the crushed areas extending adjacent to, but not all the way to each side, a slit defining a lip along a substantial length of each crushed area, the lip being located on a side of the crushed area located toward the central portion, the crushed area being crushed sufficiently to allow locking access to the lip but not forming an opening extending entirely through the sheet of material;two end roll portions, one each on opposing ends of the bottom and located between two tabs, each end roll located distal of the crushed areas and comprising an inner portion and a distal portion, the inner portion being adapted to fold along an inner fold line along a distal side of the crushed area located away from the central portion, the inner fold line being perforated through the sheet of material, the inner and distal portions being separated by an intervening fold line, the inner and intervening fold lines being parallel and perpendicular to the side fold lines, a distal edge of the distal portion having a serrated edge;wherein the inner and distal portions are sized to fold about the intervening and inner fold lines to place the serrated edge into the crushed area so the lip engages the serrated edge, and wherein the tabs are configured to be placed inside the adjacent, folded inner and distal portions.
