Blast resistant and blast directing containers, as well as doors and closures therefor, for receiving explosive articles and preventing or minimizing damage in the event of an explosion. The container comprises at least three nested bands of material wherein the bands are oriented relative to one another to substantially enclose a volume and to form a container wall having a thickness substantially equivalent to the sum of the thicknesses of at least two of the bands. The containers have utility as cargo holders, particularly in aircraft where weight is an important consideration, and as transport devices for hazardous materials such as gunpowder and explosives, e.g., bombs and grenades.

We Claim: 1. A blast resistant container comprising at least three bands of a material, a first inner band being nested within a second band which is nested within a third band, said bands being oriented relative to one another to substantially enclose a volume and to form a container wall having a thickness substantially equivalent to the sum of the thicknesses of at least two of the bands, the outermost band being substantially seamless and blast resistant, wherein each edge of the container is covered by at least one of said bands. 2. The container of claim 1 wherein each of said first, second, and third bands is a tube having a longitudinal axis, and wherein the longitudinal axes of said first, second, and third bands are substantially perpendicular to one another. 3. The container of claim 2 wherein each of the bands is substantially polygonal in cross-section. 4. The container of claim 3 wherein at least one of said bands comprises a plurality of substantially rectangular surfaces in series, said surfaces numbering at least one more than the number of sides of the polygon of the cross-section of the band, and wherein said band comprising said surfaces is nested within another said band. 5. The container of claim 3 wherein each of the bands is substantially rectangular in cross-section to thereby substantially form a rectangular prism. 6. The container of claim 5 wherein each of the bands is substantially square in cross-section to thereby substantially form a cube. 7. The container of claim 1 wherein a rigid support structure is nested within said first inner band. 8. The container of claim 7 wherein said rigid support structure comprises a low density, lightweight polymeric or metallic band. 9. The container of claim 7 wherein said first inner band is affixed to said rigid support structure. 10. The container of claim 1 wherein the band material comprises at least one fibrous layer, said fibrous layer comprising at least one network of fibers, at least about 10 weight percent of said fibers being substantially continuous lengths of fiber that encircle the enclosed volume. 11. The container of claim 10 wherein said fiber comprises a high strength fiber having a tenacity of at least about 10 g/d and a tensile modulus of at least about 200 g/d. 12. The container of claim 11 wherein said high strength fibers are selected from the group consisting of extended chain polyolefin fibers, aramid fibers, polyvinyl alcohol fibers, polyacrylonitrile fibers, liquid copolyester fibers, polyamide fibers, glass fibers, carbon fibers, and mixtures thereof. 13. The container of claim 11 wherein said fibers are polyolefin fibers. 14. The container of claim 11 wherein said fibers are aramid fibers. 15. The container of claim 11 wherein said fibers are a mixture of at least two of polyethylene fibers, aramid fibers, polyamide fibers, carbon fibers and glass fibers. 16. The container of claim 11 wherein the network of fibers is in a resin matrix. 17. The container of claim 16 wherein the matrix comprises a low modulus polymeric matrix selected from the group consisting of a low density polyethylene; a polyurethane; a flexible epoxy; a filled elastomer vulcanizate; a thermoplastic elastomer; and a modified nylon 6. 18. The container of claim 16 wherein said fiber comprises a high strength fiber having a tenacity of at least about 10 g/d and a tensile modulus of at least about 200 g/d. 19. The container of claim 18 wherein each of the bands is substantially polygonal in cross-section and deforms to increase the enclosed volume during an explosion. 20. The container of claim 16 wherein at least about 50 weight percent of said fibers are substantially continuous lengths of fiber that encircle the enclosed volume, and wherein said bands are substantially seamless. 21. The container of claim 20 wherein at least about 75 weight percent of said fibers are substantially continuous lengths of fiber that encircle the enclosed volume. 22. The container of claim 10 wherein at least about 50 weight percent of said fibers are substantially continuous lengths of fiber that encircle the enclosed volume, and wherein said bands are substantially seamless. 23. The container of claim 22 wherein at least about 75 weight percent of said fibers are substantially continuous lengths of fiber that encircle the enclosed volume. 24. The container of claim 23 wherein said fiber comprises a high strength fiber having a tenacity of at least about 10 g/d and a tensile modulus of at least about 200 g/d. 25. The container of claim 24 wherein said high strength fibers are selected from the group consisting of extended chain polyolefin fibers, aramid fibers, polyvinyl alcohol fibers, polyacrylonitrile fibers, liquid copolyester fibers, polyamide fibers, glass fibers, carbon fibers, and mixtures thereof. 26. The container of claim 24 wherein said fibers are polyolefin fibers. 27. The container of claim 24 wherein said fibers are aramid fibers. 28. The container of claim 24 wherein said fibers are a mixture of at least two of polyethylene fibers, aramid fibers, polyamide fibers, carbon fibers and glass fibers. 29. The container of claim 1 wherein said band material comprises an oriented film selected from the group consisting of homopolymers and copolymers of thermoplastic polyolefins, thermoplastic elastomers, crosslinked thermoplastics, crosslinked elastomers, polyesters, polyamides, fluorocarbons, urethanes, epoxies, polyvinylidene chloride, polyvinyl chloride, and blends thereof. 30. The container of claim 29 wherein said band material further comprises a network of fibers, at least about 10 weight percent of said fibers being substantially continuous lengths of high strength fiber that encircle the enclosed volume, said high strength fiber having a tenacity of at least about 10 g/d and a tensile modulus of at least about 200 g/d. 31. A blast resistant container comprising a rigid support structure and at least three bands of a material, a first inner band being nested within a second band which is nested within a third band, said bands being oriented relative to one another to substantially enclose a volume and to form a container wall having a thickness substantially equivalent to the sum of the thicknesses of at least two of the bands, the outermost band being substantially seamless and blast resistant, said rigid support structure comprising a low density, lightweight polymeric or metallic band nested within said first inner band and wrapped with glass or carbon fibers. 32. A blast resistant container comprising three tubular bands of a composite material, each of said bands being substantially rectangular in cross-section, a first rigid inner band being nested in a second band which is nested in a substantially seamless blast resistant third band so as to form a rectangular prism having six faces each of which has a thickness substantially equivalent to the sum of the thicknesses of at least two of the bands, each edge of the container being covered by at least one of said bands. 33.
