Abstract

A foldable corrugated corner element including at least some of a portion of material extending from a first terminal end to a second terminal end; a first corner element leg and a second corner element leg, each having one or more alternating ridges and grooves, wherein the second corner element leg extends from the first corner element leg; a notch formed in at least a portion of the first corner element leg, defined by converging sidewalls, wherein the notch allows the second corner element leg to be folded; and one or more apertures formed through a portion of the second corner element leg, wherein if the second corner element leg is folded, the apertures expand and hinges defined between adjacent apertures provide continuity for a portion of the second corner element leg.

Claims (32)

1. A foldable corrugated corner element, comprising:

a portion of material extending continuously, substantially parallel to a longitudinal axis, from a first terminal end to a second terminal end, wherein said portion of material extends continuously, substantially parallel to a transverse axis, from a first corner element end to a second corner element end;

a vertex extending substantially parallel to said longitudinal axis, between said first corner element end and said second corner element end;

a first corner element leg, extending laterally from said vertex, said first corner element leg having one or more alternating ridges and grooves, each of said alternating ridges and grooves of said first corner element leg extending substantially parallel to said longitudinal axis of said foldable corrugated corner element;

a second corner element leg, extending laterally from said vertex and away from said first corner element leg, said second corner element leg having one or more alternating ridges and grooves, each of said alternating ridges and grooves of said second corner element leg extending substantially parallel to said longitudinal axis of said foldable corrugated corner element;

a notch formed in at least a portion of said first corner element leg extending from said first corner element end toward said vertex, wherein said notch is defined by sidewalls, wherein said sidewalls converge at a converging apex, wherein said notch allows said second corner element leg to be folded, along said transverse axis, such that at least a portion of one of said sidewalls contacts or abuts at least a portion of said other sidewall;

one or more apertures formed through a portion of said second corner element leg, substantially along said transverse axis; and

a hinge defined between adjacent apertures, wherein if said second corner element leg is folded, said apertures expand and each hinge provides an area of continuity for a portion of said second corner element leg.

2. The foldable corrugated corner element of claim 1 , wherein said portion of material comprises a single layer of material.

3. The foldable corrugated corner element of claim 1 , wherein said portion of material comprises a multi-layer portion of material.

4. The foldable corrugated corner element of claim 1 , wherein said vertex is defined closer to said first corner element end than said second corner element end.

5. The foldable corrugated corner element of claim 1 , wherein said vertex is defined closer to said second corner element end than said first corner element end.

6. The foldable corrugated corner element of claim 1 , wherein each of said alternating ridges and grooves of said first corner element leg are alternating ridges and grooves, extending substantially parallel to said vertex and wherein each of said alternating ridges and grooves of said second corner element leg are alternating ridges and grooves, extending substantially parallel to said vertex.

7. The foldable corrugated corner element of claim 1 , wherein said first corner element leg and said second corner element leg are each curvilinear along a respective length.

8. The foldable corrugated corner element of claim 1 , wherein an inner wall of said first corner element leg and an inner wall of said second corner element leg comprises a sinusoidal succession of waves or curves.

9. The foldable corrugated corner element of claim 1 , wherein said notch is a substantially V-shaped notch.

10. The foldable corrugated corner element of claim 1 , wherein said notch is an indentation extending into at least a portion of said first corner element leg.

11. The foldable corrugated corner element of claim 1 , wherein said transverse axis bisects said longitudinal axis at said converging apex.

12. The foldable corrugated corner element of claim 1 , wherein said sidewalls expand away from said converging apex at 90° relative to one another, at less than 90° relative to one another, or at greater than 90° relative to one another.

13. The foldable corrugated corner element of claim 1 , wherein said apertures are substantially elliptical, oval, or ovular.

14. The foldable corrugated corner element of claim 1 , wherein said apertures are defined by substantially parallel aperture sidewalls.

15. The foldable corrugated corner element of claim 1 , wherein said apertures are formed in portions of said ridges of an outer wall of said second corner element leg and said hinges are formed in portions of said grooves of said outer wall of said second corner element leg.

16. The foldable corrugated corner element of claim 1 , wherein said apertures are formed in portions of said grooves of an outer wall of said second corner element leg and said hinges are formed in portions of said ridges of said outer wall of said second corner element leg.

17. The foldable corrugated corner element of claim 1 , wherein a score mark formed in said portion of material, extending substantially parallel to said longitudinal axis, wherein said score mark provides a line or portion along which said foldable corrugated corner element may be bent or folded such that said foldable corrugated corner element may be more easily manipulated to a more flattened position.

18. A foldable corrugated corner element, comprising:

a portion of material extending substantially parallel to a longitudinal axis, from a first terminal end to a second terminal end, wherein said portion of material extends extending substantially parallel to a transverse axis, from a first corner element end to a second corner element end;

a first corner element leg having one or more alternating ridges and grooves, each of said alternating ridges and grooves of said first corner element leg extending substantially parallel to said longitudinal axis of said foldable corrugated corner element;

a second corner element leg, extending from said first corner element leg, said second corner element leg having one or more alternating ridges and grooves, each of said alternating ridges and grooves of said second corner element leg extending substantially parallel to said longitudinal axis of said foldable corrugated corner element;

a notch formed in at least a portion of said first corner element leg extending from said first corner element end toward a said vertex, wherein said notch is defined by sidewalls, wherein said sidewalls converge at a converging apex, wherein said notch allows said second corner element leg to be folded, along said transverse axis, until at least a portion of one of said sidewalls contacts or abuts at least a portion of said other sidewall;

one or more apertures formed through a portion of said second corner element leg, substantially along said transverse axis; and

a hinge defined between adjacent apertures, wherein if said second corner element leg is folded, said apertures expand and each hinge provides an area of continuity for a portion of said second corner element leg.

19. The foldable corrugated corner element of claim 18 , wherein a score mark provides a line or portion along which said foldable corrugated corner element may be more easily manipulated to a more flattened position.
