## Abstract

A corrugated paper structure is described for providing improved impact resistant packaging products. The corrugated paper structure comprises a plurality of structural members attached to base pads for forming a packaging product. The structural members are formed from a tube of corrugated paper with a rectangular cross-section and a truss member disposed therein.

## Claims

### Claim 1

A corrugated paper structure for containing and protecting an item from impact damage, comprising:
a first and a second rectangular base pad of corrugated paper;
four structural members, each member comprising a corrugated paper tube and only one corrugated paper truss member disposed within the corrugated paper tube;
wherein the corrugated paper tube is formed from a folded sheet of corrugated paper having a first, a second, a third and a fourth panel and a glue panel, each panel extending lengthwise along the folded sheet and folded perpendicularly to the adjacent panels to form a tube with a rectangular cross-section, and the glue panel is glued to the first panel;
and the only one corrugated paper truss member is formed from a folded sheet of corrugated paper having a truss panel and two glue panels, one on either side of the truss panel, each panel extending lengthwise along the folded sheet, and each glue panel folded at an acute angle to and in opposing directions from the truss panel;
wherein the corrugated paper truss member is disposed inside the corrugated paper tube so that the truss panel of the truss member extends diagonally between opposing corners of the corrugated paper tube, and the glue panels of the truss member are glued to the inside surfaces of the first and third panels of the corrugated paper tube; and
wherein each of the four structural members is disposed between and attached to the first and second base pads adjacent to each of the four edges thereof and perpendicularly to the adjacent structural members.

### Claim 2 (depends on 1)

The corrugated paper structure of claim 1 wherein the corrugated paper tube and the corrugated paper truss member are formed from a single folded sheet of corrugated paper and the glue panel of the corrugated paper tube is also one of the glue panels of the corrugated paper truss member.

### Claim 3 (depends on 2)

The corrugated paper structure of claim 2 wherein the at least one structural members are attached to the first and second base pads by a cohesive composition applied to both the first and second base pads and the at least one structural member.

### Claim 4 (depends on 1)

The corrugated paper structure of claim 1 wherein the corrugations of the corrugated paper tube and the corrugated paper truss member are oriented perpendicular to the folds between the panels thereof.

### Claim 5 (depends on 1)

A method of using the corrugated paper structure of claim 1 to protect an item comprising the steps of:
adhering the structural members to the first rectangular base pad;
disposing an item to be protected upon the first rectangular base pad between the structural members;
adhering the second rectangular base pad to the structural members;
storing or shipping an item disposed within the corrugated paper structure;
allowing the structural members to absorb impact or crushing forces exerted on the item.
