Abstract
Abstract A one-piece multicell reinforced carton insert having an exterior boundary sidewall, a bottom floor and a plurality of cell segments, integrally formed with the exterior boundary sidewall, which may be folded together to form a plurality of reinforced cells within the insert. The cell segments depend from the bottom edge of the outer boundary wall and are folded upwardly to create bottom and sidewalls of individual cells. Adjacent cell segments are interlockable with each other and with the sidewall, and when the entire carton insert is folded in position, a plurality of cells are created in a total reinforced structure.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
81 words
A one-piece multicell reinforced carton insert comprising: an exterior boundary side wall, a plurality of cell segments integrally formed with said exterior boundary side wall and each being attached to the bottom edge of the side wall at spaced intervals therealong, each cell segment being folded to form at least a bottom and two interior side walls of two adjacent cells, and each cell segment being interlockable with at least one another adjacent cell segment to form a total reinforced structure.
Claim 2
Dependent Claim
81 words
A one-piece multicell reinforced carton insert comprising: an exterior boundary side wall, a plurality of cell segments integrally formed with said exterior boundary side wall and each being attached to the bottom edge of the side wall at spaced intervals therealong, each cell segment being folded to form at least a bottom and two interior side walls of two adjacent cells, and each cell segment being interlockable with at least one another adjacent cell segment to form a total reinforced structure.
Claim 3
Dependent Claim
46 words
A one-piece multicell reinforced carton insert as in claim 1 wherein each of said cell segments comprises at least first and second folded portions, said first folded portion forming the bottom and said second folded portion forming one side wall for each of two adjacent cells.
Claim 4
Dependent Claim
56 words
A one-piece multicell reinforced carton insert as in claim 2 wherein the second folded portion of each cell segment has an interlocking slit extending vertically thereof and substantially dividing said second folded portion into side walls of two adjacent cells and wherein the slits of adjacent cell segments extend in opposite directions for an interlocking fit.
Claim 5
Dependent Claim
48 words
A one-piece multicell reinforced carton insert in accordance with claim 2 wherein each alternate one of said cell segments has a cell side wall which is offset from the first folded portion thereof and which interlocks with a pair of cell side walls associated with two adjacent cells.
Claim 6
Dependent Claim
67 words
A one-piece multicell reinforced carton insert in accordance with claim 4 wherein said alternate ones of said cell segments each have an end cell side wall folded at a right angle to said second folded portion to generate a cell corner and wherein said end cell side wall has a tab protruding therefrom for being lockingly received by a cooperable slit in said exterior boundary side wall.
Claim 7
Dependent Claim
70 words
A one-piece multicell reinforced carton as in claim 4 wherein intermediate cell segments located between said alternate cell segments comprise said first folded portion which includes a planar section hinged to the exterior boundary side wall by a fold and said second folded portion which includes a planar section hinged to the first folded portion by a fold, said first and second folded portion being vertically aligned with one another.
Claim 8
Dependent Claim
54 words
A one-piece multicell reinforced carton insert as in claim 5 wherein said tab extends through said compartment exterior boundary side wall by a predetermined distance to space the outside surface thereof from the inside surface of a carton into which said insert is placed, thereby forming a cushion between the carton and the insert.
Claim 9
Dependent Claim
67 words
A one-piece multicell reinforced carton insert as in claim 7 wherein the first folded portion of said cell segments have tabs formed at the fold line with the exterior boundary side wall and extending outwardly a predetermined distance to space the outside surface thereof from the inside surface of a carton into which said insert is placed, thereby forming a cushion between the carton and the insert.
Claim 10
Dependent Claim
66 words
A one-piece multicell reinforced carton insert as in claim 8 wherein the upper edge of said exterior boundary side wall has a folded depending lip forming a U shaped cross section therewith to space the outside surface of the exterior boundary side wall from the inner surface of a carton into which the insert is placed, thereby forming a cushion between the carton and the insert.
Claim 11
Dependent Claim
49 words
A one-piece multicell reinforced carton insert as in claim 6 wherein one alternate and one intermediate cell segment form an interlocking pair and wherein said insert has two such pairs, said pairs being cooperable with each other together with said exterior boundary side wall for forming eight interior cells.
