Abstract

Abstract An improved palletized container construction, characterized by the provision of overlapping interlocked bottom flaps to which are secured support blocks for supporting the container in an elevated position relative to a fixed surface. More particularly, a first side bottom flap is slotted at its free extremity to define a center interlocking portion contained between a pair of outer interlocking portions. The center interlocking portion carries at least one support block that is arranged for longitudinal alignment with corresponding support blocks carried by the other side bottom wall adjacent its free corner portions. Additional rows of support blocks are carried by said side bottom flaps adjacent and parallel with their hinge lines.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 315 words
A palletized container, comprising a vertically arranged foldable blank including a succession of vertical walls hingedly connected at their vertical edges, said blank being foldable to an operative condition in which said walls define an open-ended container chamber, at least one pair of said walls being opposed and parallel when said blank is in the operative condition, said blank also including a first pair of bottom flaps (14, 18) hingedly connected with the bottom edges of said one pair of walls, the sum of the vertical dimensions of said bottom flaps normal to the hinge lines thereof being greater than the spacing distance between said one pair of walls, one of said bottom flaps (14) containing at its lower edge a pair of horizontally spaced vertical slots (20) arranged to define a central interlocking portion (14a) contained between a pair of outer interlocking portions (14b); a plurality of first support elements (24) secured to said first bottom flap adjacent the hinge line thereof; a plurality of second support elements (26) secured to said second bottom flap adjacent the hinge line thereof; at least one third support element (28) secured to said central interlocking portion of said first bottom flap; and a pair of spaced fourth support elements (30) secured to the bottom corner portions of said second bottom flap, the spacing distance between said fourth support elements being at least as great as the width of said central interlocking portion; each of said support elements having the same thickness and being arranged on the same side of said blank, said bottom flaps being foldable toward overlapping horizontal positions in which the central and outer interlocking portions of said first bottom flap are below and above the adjacent edge portion of said second bottom flap, respectively, and in which said support elements extend downwardly from said bottom flaps for supporting engagement with a fixed horizontal surface.
Claim 2
Dependent Claim 315 words
A palletized container, comprising a vertically arranged foldable blank including a succession of vertical walls hingedly connected at their vertical edges, said blank being foldable to an operative condition in which said walls define an open-ended container chamber, at least one pair of said walls being opposed and parallel when said blank is in the operative condition, said blank also including a first pair of bottom flaps (14, 18) hingedly connected with the bottom edges of said one pair of walls, the sum of the vertical dimensions of said bottom flaps normal to the hinge lines thereof being greater than the spacing distance between said one pair of walls, one of said bottom flaps (14) containing at its lower edge a pair of horizontally spaced vertical slots (20) arranged to define a central interlocking portion (14a) contained between a pair of outer interlocking portions (14b); a plurality of first support elements (24) secured to said first bottom flap adjacent the hinge line thereof; a plurality of second support elements (26) secured to said second bottom flap adjacent the hinge line thereof; at least one third support element (28) secured to said central interlocking portion of said first bottom flap; and a pair of spaced fourth support elements (30) secured to the bottom corner portions of said second bottom flap, the spacing distance between said fourth support elements being at least as great as the width of said central interlocking portion; each of said support elements having the same thickness and being arranged on the same side of said blank, said bottom flaps being foldable toward overlapping horizontal positions in which the central and outer interlocking portions of said first bottom flap are below and above the adjacent edge portion of said second bottom flap, respectively, and in which said support elements extend downwardly from said bottom flaps for supporting engagement with a fixed horizontal surface.
Claim 3
Dependent Claim 28 words
A palletized container as defined in claim 1, wherein said pair of slots are so arranged that said central and outer interlocking portions have generally the same width.
Claim 4
Dependent Claim 47 words
A palletized container as defined in claim 2, wherein said third and fourth support elements are so connected with their respective flaps as to effect alignment of said elements in a row extending longitudinally of the container when said bottom flaps are folded to said horizontal positions.
Claim 5
Dependent Claim 32 words
A palletized container as defined in claim 3, wherein said support elements are also arranged in rows extending transversely of the container when said bottom flaps are folded to said horizontal positions.
Claim 6
Dependent Claim 59 words
A paLletized container as defined in claim 1, wherein said support elements are connected with their respective bottom flaps in such a manner that when said bottom flaps are folded toward their horizontal positions, said support elements are arranged in spaced rows extending both longitudinally and transversely of the container, thereby affording four-way access for a fork lift truck.
Claim 7
Dependent Claim 42 words
A palletized container as defined in claim 1, and further including tab means secured to at least one of said walls for permanently securing together the free vertical edges of the first and last ones of said hingedly connected succession of walls.
Claim 8
Dependent Claim 82 words
A palletized container as defined in claim 1, wherein said blank includes four of said walls for defining a rectangular container, said first pair of opposed walls being the side walls of said container, and further including end bottom flaps (12, 16) hingedly connected with the bottom edges of the end walls of said container, said end bottom flaps being foldable to horizontal positions above said first pair of bottom flaps, thereby to effect complete sealing of the bottom of the container.
Claim 9
Dependent Claim 56 words
A palletized container as defined in claim 7, wherein said bottom flaps are each in a vertical orientation, said container may be collapsed to a condition in which one of each of said side and end walls are contained in one plane, and the remaining side and end walls are contained in an adjacent parallel plane.
