Abstract

Abstract A resilient cushioning dunnage product of helical coil like configuration produced from a web of low cost sheet like material, such as paper, by crumpling the web down into a relatively narrow strip and then forming the strip by pressure into generally helical coiled form. Also a tubular like dunnage product formed by taking a web of flexible sheet like material, such as paper, forming the web into generally tubular-like shape by moving lengthwise edges of the web inwardly toward one another and then loosely crumpling the tubular-like product and stitching it along the lengthwise extent thereof to maintain the formed configuration.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 42 words
Dunnage for packing comprising, an elongated relatively narrow compressed strip of crumpled sheet-paper material formed into generally helicallike coil configuration in a direction lengthwise thereof, opposite faces of said strip being coined into spaced corrugations extending generally tranversely of said strip faces.
Claim 2
Dependent Claim 42 words
Dunnage for packing comprising, an elongated relatively narrow compressed strip of crumpled sheet-paper material formed into generally helicallike coil configuration in a direction lengthwise thereof, opposite faces of said strip being coined into spaced corrugations extending generally tranversely of said strip faces.
Claim 3
Dependent Claim 23 words
A dunnage product in accordance with claim 1 wherein the dunnage product comprises portions of said helicallike coiled configuration alternated with noncoiled portions.
Claim 4
Dependent Claim 107 words
A dunnage product in accordance with claim 2 wherein each of said noncoiled portions comprises a strip section extending generally linearly in the lengthwise direction of said dunnage product, each of said coiled portions comprising a plurality of helicallike coils, each of said linear sections being disposed intermediate lengthwise spaced of said coiled portions, each of said linear sections being coined into corrugations extending generally transversely thereof, said noncoiled portions of the dunnage product being adapted to cause the dunnage to be resistant to lengthwise axial collapsing and insuring that the dunnage material when packed into a container becomes a tanGled resilient mass, possessing good cushioning characteristics.
Claim 5
Dependent Claim 81 words
A dunnage product in accordance with claim 3 wherein the product is of a relatively low density and wherein one lengthwise edge thereof is comprised of relatively loosely crumpled material forming an enlarged edge portion extending for the full length of said product, said strip tapering in a direction transversely thereof toward the opposite edge portion which is relatively highly compressed and of a smaller cross sectional area as compared to the cross sectional area of the first mentioned edge portion.
