Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 249 words
In a four-cell partition arrangement formed from a unitary blank of foldable paperboard, the combination of: a. a generally rectangular outer bottom panel; b. a transverse partition member cut from material of said outer bottom panel and including: i. a first vertical element; ii. a generally triangular gusset element foldably connected at one edge to a lower edge of said first vertical element on one fold line extending transversely of said outer bottom panel, foldably connected along another edge to said outer bottom panel along another fold line which diverges from said one fold line at an angle of less than 90°, and being disposed in face-to-face engagement with the upper surface of said outer bottom panel; c. a longitudinal partition member including: i. a second vertical element; ii. an inner bottom panel foldably connected at one side edge to a side edge of said outer bottom panel, foldably connected at another side edge to a lower edge of said second vertical element, and being disposed in face-to-face engagement with the upper surface of said outer bottom panel to cover at least a portion of the opening formed by the removal of the material for said transverse partition member; iii. said second vertical element and said inner bottom panel having aligned slots for receiving a portion of said first vertical element; d. said first vertical element having a slot extending downwardly from its upper edge for receiving a portion of said second vertical element to provide interlocking engagement therebetween.
Claim 2
Dependent Claim 249 words
In a four-cell partition arrangement formed from a unitary blank of foldable paperboard, the combination of: a. a generally rectangular outer bottom panel; b. a transverse partition member cut from material of said outer bottom panel and including: i. a first vertical element; ii. a generally triangular gusset element foldably connected at one edge to a lower edge of said first vertical element on one fold line extending transversely of said outer bottom panel, foldably connected along another edge to said outer bottom panel along another fold line which diverges from said one fold line at an angle of less than 90°, and being disposed in face-to-face engagement with the upper surface of said outer bottom panel; c. a longitudinal partition member including: i. a second vertical element; ii. an inner bottom panel foldably connected at one side edge to a side edge of said outer bottom panel, foldably connected at another side edge to a lower edge of said second vertical element, and being disposed in face-to-face engagement with the upper surface of said outer bottom panel to cover at least a portion of the opening formed by the removal of the material for said transverse partition member; iii. said second vertical element and said inner bottom panel having aligned slots for receiving a portion of said first vertical element; d. said first vertical element having a slot extending downwardly from its upper edge for receiving a portion of said second vertical element to provide interlocking engagement therebetween.
Claim 3
Dependent Claim 250 words
In a partition arrangement formed from a unitary blank of foldable paperboard, the combination of: a. an outer bottom panel; b. a first partition member cut from material of said outer bottom panel and including; i. a first vertical element; ii. a generally triangular gusset element foldably connected at one edge to a lower edge of said first vertical element on one fold line, foldably connected along another edge to said outer bottom panel along another fold line which diverges from said one fold line at an angle of less than 90°, and being disposed in face-to-face engagement with the upper surface of said outer bottom panel; c. a second partition member disposed at an angle with respect to said first partition member and including: i. a second vertical element; ii. an inner bottom panel foldably connected at one side edge to a side edge of said outer bottom panel, foldably connected at another side edge to a lower edge of said second vertical element, and being disposed in face-to-face engagement with the upper surface of said upper bottom panel to cover at least a portion of the opening formed by the removal of the material for said first partition member; iii. said second vertical element and said inner bottom panel having aligned slots for receiving a portion of said first vertical element; d. said first vertical element having a slot extending from its upper edge for receiving a portion of said second vertical element to provide interlocking engagement therebetween.
Claim 4
Dependent Claim 250 words
In a partition arrangement formed from a unitary blank of foldable paperboard, the combination of: a. an outer bottom panel; b. a first partition member cut from material of said outer bottom panel and including; i. a first vertical element; ii. a generally triangular gusset element foldably connected at one edge to a lower edge of said first vertical element on one fold line, foldably connected along another edge to said outer bottom panel along another fold line which diverges from said one fold line at an angle of less than 90°, and being disposed in face-to-face engagement with the upper surface of said outer bottom panel; c. a second partition member disposed at an angle with respect to said first partition member and including: i. a second vertical element; ii. an inner bottom panel foldably connected at one side edge to a side edge of said outer bottom panel, foldably connected at another side edge to a lower edge of said second vertical element, and being disposed in face-to-face engagement with the upper surface of said upper bottom panel to cover at least a portion of the opening formed by the removal of the material for said first partition member; iii. said second vertical element and said inner bottom panel having aligned slots for receiving a portion of said first vertical element; d. said first vertical element having a slot extending from its upper edge for receiving a portion of said second vertical element to provide interlocking engagement therebetween.
Claim 5
Dependent Claim 43 words
A partition arrangement according to claim 2, wherein said first vertical element has a corner portion recessed adjacent the slot in said inner bottom panel to accommodate the passage of said first vertical element through said inner bottom panel slot during erection thereof.
Claim 6
Dependent Claim 75 words
A partition arrangement according to claim 2, and including at least one end partition member, comprising: a. an outer panel foldably connected at its lower edge to an end edge of said outer bottom panel; b. an inner panel foldably connected at a side edge to a side edge of said outer panel and folded into face-to-face engagement with the inner surface of said outer panel adjacent an end edge of said second vertical element.
