Abstract

Abstract Container-forming material and containers formed thereby, the material being in a single sheet and including a layer of resilient, flexible cushioning material secured to a sheath or backing member which is flexible, so that a container is easily formed thereof e.g. manually by placing an article of substantially any shape on the cushioning material and rolling up the combined cushioning material with its backing or sheath, and then securing the edges together in a cylinderlike complete package; the cushioning material being compressed to some extent by this action, particularly in the area of the encompassed article; in addition end covers or caps may be applied to the rolled-up container aiding in maintaining the edges thereof together to form the complete package, with the sheath covering the entire outside of the package except for the ends; and in some cases applying cushioning material to the end caps themselves so as to prevent especially small heavy articles from shifting lengthwise of the package under impact to such an extent as to become damaged. Urethane foam or other like resilient material and a singlefaced corrugated board or the like, together make an ideal combination which can be rolled uniformly to form the package, somewhat in the nature of a mailing tube. Any profile or contour, including special article receiving cavities can be applied to the foam cushioning, or it may be coplanar, but in any case it is continuous across the sheet.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 110 words
A container comprising a sheet of material including a layer of yielding, deformable, foamed, cellular cushioning, and a layer of backing secured together in superposed relation, said cushioning having an exposed alternate, closely spaced conical projection and complementary depression contour, said container material being cylindrically rolled upon itself with the cushioning inside and the backing outside, opposite free edges of said sheet of material being substantially in contact with each other to form an enclosure, and the projections in general interfitting with the depressions, said cushioning substantially filling the enclosure in generally undeformed condition, and means adapted to encompass the enclosure holding the sheet of material in enclosure forming condition.
