Abstract

A modular corrugated container integrates product cushioning with a product support surface formed from corrugated paper and having features that absorb transverse accelerations. The support surface has scored tabs that bend perpendicular to an interior support portion, forming feet that elevate the interior portion relative to a container bottom. The interior portion has perforations that absorb accelerations, such as a perforations formed around the outside perimeter of the location at which a product rests, perforations extending from corners of the support surface towards a central location of the support surface, and perforations at the scoring of the tabs. Voids formed along the tabs remove portions of the feet from contact with the container bottom to encourage constant dissemination of accelerations across the support surface.

First claim

What is claimed is:

1. A system for packaging a product, the product having a perimeter, the system comprising:
an outer packaging material enclosing the product between an upper surface and a lower surface;
first and second support surfaces formed from corrugated material and held elevated between the upper surface and the lower surface, the first and second support surfaces each having a perforation formed substantially at the product perimeter, the support surface providing a flat surface across the perforations, each of the first and second support surfaces having bent tabs along a periphery, the tabs bent substantially perpendicular to the support surface to define feet that elevate the support surface, the tabs having indented portions that do not contact the outer packaging material; and
a positioning device operable to maintain the product in a position at the perforation;
wherein the product is disposed between the first and second support surfaces so that accelerations applied to the product translate through the perforation to the tabs where the tabs contact the outer packaging material.

2. The system of claim 1 wherein the product perimeter has a rectangular shape, the perforation has a rectangular shape with a perimeter greater than the product perimeter, and the support surface further having a cut formed at each corner of the perforation, each cut extending from the perforation corner diagonally outwards towards the outer packaging material, the cut passing completely through the support surface for a contiguous distance.

3. The system of claim 2 wherein the support surface further has a cut formed at each corner of the perforation, each cut extending from the perforation corner diagonally inwards towards a center position of the perimeter, the cut passing completely through the support surface for a contiguous distance.

4. The system of claim 1 wherein the positioning device further comprises a cushion disposed between the outer packaging material and the perimeter.

5. The system of claim 1 wherein the product is a portable information handling system that rests on the support surface.

6. A method for forming a product package to contain a product, the method comprising:
forming a container having an upper surface and a lower surface and having an interior and an exterior;
cutting first and second support surfaces from corrugated paper, each support surface having a rectangular shape with a tab formed along each side, the tabs folding perpendicular to the support surface to form feet that raise the support surface relative to the lower and upper surfaces, the feet contacting the container at contact portions, the feet having voids disposed between the contact portions, the voids not contacting the container;
perforating a rectangular shape in each support surface to have a perimeter of substantially the same size as the product; and
maintaining a product position on the first and second support surfaces, the product position substantially at the perforated rectangular shape and disposed between the first and second support surfaces so that accelerations applied to a product placed at the product position pass through the first and second support surface perforations to the feet contact portions.

7. The method of claim 6 further comprising perforating in each of the first and second support surfaces from each corner of the perforated rectangular shape outward towards the container exterior.

8. The method of claim 6 further comprising perforating in each of the first and second support surfaces from each corner of the perforated rectangular shape inward toward a center position of the container interior.

9. The method of claim 6 wherein cutting a support surface further comprises perforating at least a portion of the support surface along the folding position of the tabs.

10. The method of claim 6 wherein maintaining a product position further comprises disposing cushioning between the container exterior and the perforated rectangular shape.

11. A method for forming product support surfaces to support a product in a shipping container, the method comprising:
cutting the product support surfaces from first and second pieces of corrugated paper;
scoring tabs along side edges of the product support surfaces;
bending the tabs to form feet that elevate an interior portion of the product support surface relative to a bottom support surface, the feet formed along the full periphery of the support surface and having voids that define contact regions, the contact regions sized to contact the shipping container so that the voids do not contact the shipping container;
perforating the interior portion with at least one symmetrical pattern that allows deflection of the interior portion in response to a transverse acceleration; and
disposing the first and second product surfaces on opposing surfaces of the product with the product between the first and second product support surfaces so that accelerations acting on the product translate through the support surface perforations to the contact regions.

12. The method of claim 11 wherein perforating the interior portion with at least one symmetrical pattern further comprises perforating a shape within the interior portion having a perimeter substantially that of the product.

13. The method of claim 12 wherein perforating the interior portion with at least one symmetrical pattern further comprises perforating a line from each of the corners of the side edges across the perforated shape towards a central position of the interior portion.
