## Abstract

A palletized container system including deck and runner structure formed from a unitary deck sheet of corrugated material having top and bottom generally planar surfaces and opposite parallel sides. The deck sheet is folded downwardly and then upwardly at each of its sides to form fore-and-aft extending outer runners unitary with the remainder of the sheet to provide outer runner lateral stability. An elongated central runner is fixed to the bottom of the sheet and extends parallel to the outer runners. A corrugated wrapper extends under the central and side runners and is folded around the side runners and over the deck sheet. The wrapper has upper planar portions extending inwardly from the side portions of the side runners toward the central runner and fixed to the top planar surface. A one-piece liner board is fixed to the upper planar portions of the wrapper to increase strength and includes flaps folded upwardly to slidably receive an open bottom container.

## Claims

### Claim 1

A pallet component adapted for receipt of and movement by the forks of a fork pallet truck, the pallet component comprising:
a unitary sheet of corrugated material having top and bottom generally planar surfaces and opposed parallel sides, inner and outer panels defined at each of said opposed parallel sides by fore-and-aft extending inner and outer fold lines running parallel to the sides, said inner and outer panels folded together about each of said outer fold lines into facing contact with each other, the folded together inner and outer panels folded downwardly along each of said inner fold lines to form fore-and-aft extending outer or side runners unitary with the remainder of the sheet to provide outer runner lateral stability;
a central runner fixed to the bottom of the sheet generally parallel to said outer runners to define with the outer runners fore-and-aft extending fork receiving areas; and
a wrapper extending under the central and side runners, the wrapper folded around the side runners about fold lines parallel to the side runners so that the side runners are surrounded on their bottom, side and top portions, the wrapper having upper planar portions extending inwardly from the side portions of the side runners toward the central runner, wherein the wrapper extends inwardly toward the central runner and is fixed to the top planar surface to provide lateral stability to the side runners.

### Claim 2 (depends on 1)

The pallet component as set forth in claim 1 wherein the wrapper comprises corrugated material of preselected thickness, wherein the side runners have a combined thickness at least twice as great as said preselected thickness.

### Claim 3 (depends on 1)

The pallet component as set forth in claim 1 including a top member fixed to the upper planar portions and extending over the central runner.

### Claim 4 (depends on 1)

The pallet component as set forth in claim 1 wherein the pallet wrapper comprises a single piece of corrugated material forming a continuous wrap under the side and central runners and around the side runners.

### Claim 5 (depends on 4)

The pallet component as set forth in claim 4 wherein the wrapper has opposite edges offset from each other on opposite sides of the central runner at the top planar surface, and further including a carton bottom piece fixed to the top of the wrapper and providing reinforcement to the pallet component.

### Claim 6 (depends on 1)

The pallet component as set forth in claim 1 wherein the fold lines define inner and outer panels of generally equivalent width at each side of the sheet.

### Claim 7 (depends on 6)

The pallet component as set forth in claim 6 wherein the outer fold lines are cut scored and the inner and outer panels at each side are folded against each other about the outer fold lines.

### Claim 8 (depends on 1)

The pallet component as set forth in claim 1 further comprising a top member fixed to the upper planar portions of the pallet wrapper, the top member providing reinforcement to the upper planar portions.

### Claim 9 (depends on 8)

The pallet component as set forth in claim 8 wherein the top member includes flaps adapted for folding upwardly.

### Claim 10 (depends on 9)

The pallet component as set forth in claim 9 further comprising a container portion having an open bottom, wherein the container portion is slidably received over the upwardly folded flaps to define with the top member a closed container secured to the wrapper.

### Claim 11 (depends on 6)

The pallet component as set forth in claim 6 wherein each inner panel is glued to the adjacent outer panel, and wherein the wrapper is glued to the side runners.

### Claim 12

A corrugated fiber pallet comprising a deck sheet of rectangular configuration and preselected thickness, the sheet having opposed sides and first and second fold lines at each side, the fold lines extending in the fore-and-aft direction to define first and second narrow parallel panels, the first panel folded about the first fold line to a position against the second panel, the first and second panels folded about the second fold line approximately 90 degrees from the plane of the remainder of the sheet to define an upper deck portion with a downwardly projecting side runner at each side of the deck portion, the side runners having a width at least approximately twice the preselected thickness, a central runner attached to a bottom of said upper deck portion, a wrapper of corrugated material extending under the side and central runners and around and over the side runners into the deck portion, and wherein the wrapper is secured to the side and central runners and to the deck portion between the runners.

### Claim 13 (depends on 12)

The corrugated fiber pallet as set forth in claim 12 further comprising a top sheet fixed to the deck portion.

### Claim 14 (depends on 13)

The corrugated fiber pallet as set forth in claim 13 wherein the top sheet comprises a unitary corrugated sheet defining a container bottom section.

### Claim 15 (depends on 14)

The corrugated fiber pallet as set forth in claim 14 wherein the unitary corrugated sheet includes a bottom panel conforming to the shape of the deck portion and foldable side flaps extending outwardly from the bottom panel and adapted for folding upwardly to receive a container thereon.

### Claim 16 (depends on 12)

The corrugated fiber pallet as set forth in claim 12 wherein the wrapper comprises a double wall corrugated fiber sheet and the deck sheet comprises a triple wall corrugated fiber sheet.

### Claim 17 (depends on 12)

The corrugated fiber pallet as set forth in claim 12 wherein the first and second panels include adjacent faces, the adjacent faces glued to each other, and wherein the wrapper is glued to the central and side runners and to the deck portion.
