Foldable storage box

Claim 2

A box having an open top and folded from a flat single-piece blank comprising, two outer side walls and two outer end walls formed into a rectangle with the side walls and end walls respectively opposite each other and connected together at their adjacent edges, two inner side walls hinged to the upper edges of the two outer side walls and folded downwardly to positions inside the rectangle to form two-ply side walls with the plies of each side wall being substantially coextensive with each other, an outer bottom wall attached to the lower edge of one of the outer side walls with two intermediate end walls attached thereto at opposite ends and positioned inside the outer end walls when the bottom section is folded upwardly to a position closing the bottom of the rectangle, an inner bottom wall attached to the lower edge of the opposite outer side wall and positioned above the outer bottom waLl, and two inner end walls attached to the upper edges of the outer end walls and folded downwardly inside the rectangle to enclose the intermediate end walls between them and the outer end walls to provide a box from a flat blank having three-ply end walls, with each of said end walls being substantially coextensive with each other.

Claim 3

A folding box blank of flat, rectangular material that is scored and cut for folding into a box, said blank comprising a central portion extending completely across the blank and having three parallel spaced apart transverse scores so that the central portion is scored for folding into a rectangular shape to provide outer end and side walls of the box, an edge portion having a first section including two intermediate end walls and the lower bottom of the box, said first section being attached to the central portion between the edge of the lower bottom side and one of the outer side walls of the central portion, said intermediate end walls being cut from the central portion end attached only to the lower bottom portion, said first edge portion further having a second section attached to the other outer side wall of the central portion and scored along said connection for folding to a position to close the bottom, said blank having a second edge portion extending along the opposite edge of the central portion from the first edge portion, the second edge portion having three parallel, spaced cuts respectively longitudinally aligned with the three transverse scores in said central portion so that the second edge portion provides two inner end walls and two inner side walls so that said inner end walls can be folded down inside the box parallel to the intermediate end walls to provide three-ply opposing end walls and so that said inner side walls can be folded down inside the box parallel to the outer side walls to provide two-ply opposing side walls, all of said end walls being individually integral and each being substantially coextensive with the other end walls and all of the side walls being individually integral and each being substantially coextensive with the other side walls.

Claim 4

A folding box blank of flat, rectangular material that is scored and cut for folding into a box, said blank comprising a central portion extending completely across the blank and having three parallel spaced apart transverse scores so that the central portion is scored for folding into a rectangular shape to provide outer end and side walls of the box, an edge portion having a first section including two intermediate end walls and the lower bottom of the box, said first section being attached to the central portion between the edge of the lower bottom side and one of the outer side walls of the central portion, said intermediate end walls being cut from the central portion end attached only to the lower bottom portion, said first edge portion further having a second section attached to the other outer side wall of the central portion and scored along said connection for folding to a position to close the bottom, said blank having a second edge portion extending along the opposite edge of the central portion from the first edge portion, the second edge portion having three parallel, spaced cuts respectively longitudinally aligned with the three transverse scores in said central portion so that the second edge portion provides two inner end walls and two inner side walls so that said inner end walls can be folded down inside the box parallel to the intermediate end walls to provide three-ply opposing end walls and so that said inner side walls can be folded down inside the box parallel to the outer side walls to provide two-ply opposing side walls, all of said end walls being individually integral and each being substantially coextensive with the other end walls and all of the side walls being individually integral and each being substantially coextensive with the other side walls.

Claim 5

A storage box having an open top closeable by a separate lid comprising two outer side walls and two outer end walls connected together at their adjacent edges so as to provide a rectangular configuration; an inner bottom wall hinged at one side to a first one of said outer side walls; an outer bottom wall hinged at one side to the other one of said outer side walls; two integral intermediate end walls each respectively hinged to the opposite ends of the outer bottom wall which ends are adjacent the outer end walls and extending substantially coextensively with the respective outer end walls; two integral inner end walls each respectively hinged to the upper ends of said outer end walls, folded over the upper edges of the intermediate end walls and extending downwardly substantially coextensively with the intermediate end walls so as to provide the box with three-ply ends with each ply being individually integral and substantially coextensive with the other plies; and two integral inner side walls respectively hinged to the upper ends of said outer side walls and extending substantially coextensively with the outer side walls so as to provide the box with two-ply sides with each ply being individually integral and substantially coextensive with the other ply.

Claim 6

A storage box having an open top closeable by a separate lid comprising two outer side walls and two outer end walls connected together at their adjacent edges so as to provide a rectangular configuration; an inner bottom wall hinged at one side to a first one of said outer side walls; an outer bottom wall hinged at one side to the other one of said outer side walls; two integral intermediate end walls each respectively hinged to the opposite ends of the outer bottom wall which ends are adjacent the outer end walls and extending substantially coextensively with the respective outer end walls; two integral inner end walls each respectively hinged to the upper ends of said outer end walls, folded over the upper edges of the intermediate end walls and extending downwardly substantially coextensively with the intermediate end walls so as to provide the box with three-ply ends with each ply being individually integral and substantially coextensive with the other plies; and two integral inner side walls respectively hinged to the upper ends of said outer side walls and extending substantially coextensively with the outer side walls so as to provide the box with two-ply sides with each ply being individually integral and substantially coextensive with the other ply.
