Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
129 words
A space divider formed from a single blank of sheet material for use within the interior of a container, said divider comprising at least one bottom panel adapted to overlie the bottom of the container; an upright partition disposed transversely of said bottom panel; pairs of upright side panels, one pair being foldably connected to said bottom panel, corresponding side panels of said pairs being disposed on opposite sides of said partition panel and extending angularly therefrom; and connecting panels foldably interconnecting said corresponding side panels, each connecting panel having foldable sections, one section being foldably connected to one corresponding side panel, and a second section being foldably connected to a second corresponding side panel, said second section being connected to said partition panel by a diagonally extending foldline.
Claim 2
Dependent Claim
129 words
A space divider formed from a single blank of sheet material for use within the interior of a container, said divider comprising at least one bottom panel adapted to overlie the bottom of the container; an upright partition disposed transversely of said bottom panel; pairs of upright side panels, one pair being foldably connected to said bottom panel, corresponding side panels of said pairs being disposed on opposite sides of said partition panel and extending angularly therefrom; and connecting panels foldably interconnecting said corresponding side panels, each connecting panel having foldable sections, one section being foldably connected to one corresponding side panel, and a second section being foldably connected to a second corresponding side panel, said second section being connected to said partition panel by a diagonally extending foldline.
Claim 3
Dependent Claim
20 words
The space divider of claim 1 wherein the side panels of each pair are disposed in spaced, substantially parallel relation.
Claim 4
Dependent Claim
24 words
The space divider of claim 2 wherein the corresponding side panels of said pairs of upright side panels are disposed in substantially coplanar relation.
Claim 5
Dependent Claim
27 words
The space divider of claim 1 wherein said partition panel is provided with laterally extending shoulder portions which are sandwiched between the sections of said connecting panels.
Claim 6
Dependent Claim
32 words
The space divider of claim 4 wherein said partition panel includes an upwardly projecting center portion wherein the upper edge thereof is substantially coterminous with the upper edges of said side panels.
Claim 7
Dependent Claim
21 words
The space divider of claim 1 wherein the lower edge of said partition panel is foldably connected to said bottom panel.
Claim 8
Dependent Claim
168 words
A blank of foldable sheet material adapted to form a space divider having bottom panels separated by a transversely extending upright partition panel, parallel side panels extending upright from the bottom panels and separated by said partition panel, and upright connecting panels interconnecting corresponding side panels disposed oN opposite sides of said partition panel; said blank comprising a partition panel, a pair of bottom panels disposed on opposite sides of said partition panel, a pair of first side panels foldably connected to and extending laterally outwardly in opposite directions from one bottom panel, a pair of second side panels foldably connected to and extending laterally ouwardly in opposite directions from the second bottom panel, and a pair of connecting panels laterally disposed on opposite sides of said partition panel, each connecting panel interconnecting corresponding first and second side panels and being provided with foldably connected sections, one section of each connecting panel being connected to a peripheral segment of said partition panel by a substantially diagonally extending foldline.
Claim 9
Dependent Claim
168 words
A blank of foldable sheet material adapted to form a space divider having bottom panels separated by a transversely extending upright partition panel, parallel side panels extending upright from the bottom panels and separated by said partition panel, and upright connecting panels interconnecting corresponding side panels disposed oN opposite sides of said partition panel; said blank comprising a partition panel, a pair of bottom panels disposed on opposite sides of said partition panel, a pair of first side panels foldably connected to and extending laterally outwardly in opposite directions from one bottom panel, a pair of second side panels foldably connected to and extending laterally ouwardly in opposite directions from the second bottom panel, and a pair of connecting panels laterally disposed on opposite sides of said partition panel, each connecting panel interconnecting corresponding first and second side panels and being provided with foldably connected sections, one section of each connecting panel being connected to a peripheral segment of said partition panel by a substantially diagonally extending foldline.
Claim 10
Dependent Claim
20 words
The blank of claim 7 wherein one bottom panel is foldably connected to a peripheral segment of said partition panel.
Claim 11
Dependent Claim
58 words
The blank of claim 7 wherein said partition panel has an elongated center portion, a part of which is disposed between and separated from corresponding first sections of said connecting panels, and laterally extending shoulder portions connected to corresponding second sections of said connecting panels by substantially diagonally extending foldlines, said shoulders being separated from said first sections.
Claim 12
Dependent Claim
45 words
The blank of claim 9 wherein said blank has a substantially rectangular peripheral configuration, and one of said bottom panels is foldably connected to a segment of the center portion of said partition panel disposed opposite the part thereof positioned between said corresponding first sections.
