Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
137 words
A collapsible box having four interconnected sidewalls, closure means, an interior cellular partition, said partition comprising a plurality of elongated strips, each of said strips having a hinged tab at each end, each of said strips having transverse lines of weakness at predetermined intervals to define main cell panels therebetween, said strips being folded alternately counter clockwise and clockwise along their length about said lines of weakness to position adjacent main cell panels of the same strip at substantially a right angle to one another, said strips being arranged to form a plurality of individual substantially rectangular cells, and means connecting said strips with said lines of weakness of one strip lying generally adjacent said lines of weakness of the next adjacent strip, and means attaching said end tabs to the interior surfaces of said interconnected sidewalls.
Claim 2
Dependent Claim
137 words
A collapsible box having four interconnected sidewalls, closure means, an interior cellular partition, said partition comprising a plurality of elongated strips, each of said strips having a hinged tab at each end, each of said strips having transverse lines of weakness at predetermined intervals to define main cell panels therebetween, said strips being folded alternately counter clockwise and clockwise along their length about said lines of weakness to position adjacent main cell panels of the same strip at substantially a right angle to one another, said strips being arranged to form a plurality of individual substantially rectangular cells, and means connecting said strips with said lines of weakness of one strip lying generally adjacent said lines of weakness of the next adjacent strip, and means attaching said end tabs to the interior surfaces of said interconnected sidewalls.
Claim 3
Dependent Claim
49 words
The box of claim 1 wherein said strips each Have a pair of spaced lines of weakness at said predetermined intervals to provide a short transitional panel therebetween and with said transitional panel of one strip lying in surface contact with said transitional panel of the next adjacent strip.
Claim 4
Dependent Claim
21 words
The box of claim 2 wherein said contacting transitional panels are adhesively connected over a major portion of their contacting surfaces.
Claim 5
Dependent Claim
35 words
The box of claim 2 wherein the longitudinally extending dimension between said pair of spaced lines of weakness is between about 1/4 inch and about 25 percent of the diagonal dimension of an individual cell.
Claim 6
Dependent Claim
39 words
A collapsible box in accordance with claim 1 which is rectangular in cross section and wherein said substantially rectangular individual cells are arranged side-by-side in aligned rows extending parallel to the length and to the width of said box.
Claim 7
Dependent Claim
121 words
A collapsible box having four interconnected sidewalls, closure means, and an interior cellular partition, said partition comprising a plurality of elongated strips, each of said strips having tabs at each end and having alternating main cell panel sections and transitional panel sections, each of said strips being folded alternately counter clockwise and clockwise at the pairs of junctions between said main cell panel sections and each of said transitional panel sections, each transitional panel section of each of said strips being adhesively connected in surface contact with a transitional panel section of an adjacent strip, thereby defining a plurality of substantially rectangular cells arranged in rows, and said end tabs being adhesively connected to the interior surfaces of said interconnected sidewalls.
Claim 8
Dependent Claim
121 words
A collapsible box having four interconnected sidewalls, closure means, and an interior cellular partition, said partition comprising a plurality of elongated strips, each of said strips having tabs at each end and having alternating main cell panel sections and transitional panel sections, each of said strips being folded alternately counter clockwise and clockwise at the pairs of junctions between said main cell panel sections and each of said transitional panel sections, each transitional panel section of each of said strips being adhesively connected in surface contact with a transitional panel section of an adjacent strip, thereby defining a plurality of substantially rectangular cells arranged in rows, and said end tabs being adhesively connected to the interior surfaces of said interconnected sidewalls.
Claim 9
Dependent Claim
39 words
A collapsible box in accordance with claim 6 which is rectangular in cross section and wherein said substantially rectangular individual cells are arranged side-by-side in aligned rows extending parallel to the length and to the width of said box.
Claim 10
Dependent Claim
37 words
A box in accordance with claim 6 wherein the longitudinal dimension of said transitional panels is at least about 1/4 inch and not greater than about 25 percent of the diagonal dimension of said substantially rectangular cell.
