Abstract

A plurality of integrally arranged panels include a first panel and a second panel with a fold line therebetween. A compression reinforcement feature has a planar edge oriented orthogonal to a first planar surface of the first panel and perpendicular to a z-axis that defines a stacking load direction, the planar edge being disposed at a distance away from the fold line of half a thickness of the first panel, the first panel having a void between the fold line and the planar edge. The compression reinforcement feature is formed by at least four cut lines that define at least a portion of a closed perimeter of a cutout. One of the cut lines defines a location of the planar edge of the compression reinforcement feature.

Claims

1. A container, comprising:

a plurality of panels integrally arranged with respect to each other and with respect to a set of orthogonal x, y and z axes, the z-axis defining a direction line in which the container is configured to support a stacking load, the plurality of panels fabricated from a corrugated fiber board material;

wherein the plurality of panels comprise a first panel comprising a first planar surface, and a second panel comprising a second planar surface, wherein the first panel and the second panel form a contiguity with a fold line disposed therebetween, wherein the first planar surface is disposed parallel to the x-z plane or the y-z plane, wherein the first panel and the second panel are folded orthogonal with respect to each other about the fold line; and

a compression reinforcement feature having a planar edge oriented orthogonal to the first planar surface and perpendicular to the z-axis, the planar edge being disposed at a distance away from the fold line of half a thickness of the first panel, the first panel comprising a void between the fold line and the planar edge;

wherein the compression reinforcement feature is formed by a cut line that begins at a first point on the second panel, traverses a first distance along a first line that extends across the fold line, traverses a second distance along a second line that runs substantially parallel to the fold line, traverses a third distance along a third line that extends back across the fold line, and traverses a fourth distance along a fourth line to end at the first point, wherein the first, second, third and fourth lines define at least a portion of a closed perimeter of a cutout, and wherein the second line defines a location of the planar edge of the compression reinforcement feature.

2. The container of claim 1, wherein:

the planar edge is oriented orthogonal to a longitudinal direction of flutes of the corrugated fiber board.

3. The container of claim 1, wherein:

the corrugated fiber board material has an A-flute, B-flute, C-flute, E-flute, F-flute, or microflute configuration.

4. A flat blank, comprising:

a first panel and a second panel that form a contiguity with a fold line disposed therebetween, the first and second panels fabricated from a corrugated fiber board material; and

a compression reinforcement feature formed by a cut line that begins at a first point on the second panel, traverses a first distance along a first line that extends across the fold line, traverses a second distance along a second line that runs substantially parallel to the fold line, and traverses a third distance along a third line that extends back across the fold line to end at a second point on the second panel, wherein the cut line further comprises at least a fourth line that connects the first point to the second point to define a closed perimeter of a cutout, wherein the second line defines a location of a planar edge of the compression reinforcement feature, wherein when the first panel and the second panel are folded orthogonal with respect to each other about the fold line the planar edge is disposed at a distance away from the fold line of half a thickness of the first panel.

5. The flat blank of claim 4, wherein:

the planar edge is oriented orthogonal to a longitudinal direction of flutes of the corrugated fiber board.
