Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 142 words
A blank adapted to form an interior partition within a carton and an extensible handle member, said blank comprising a handle panel having a hand section and abutment flanges, a securing panel, a line of weakness connecting said handle panel to said securing panel to permit said handle panel to be torn therefrom, an envelope panel, a partition panel, said securing panel and said partition panel being connected to said envelope panel by substantially parallel fold lines positioned one on each end of said envelope panel and a handle opening along said fold line connection between said partition panel and said envelope panel, said opening permitting the handle section to be pulled through said opening into a carrying position wherein said flanges engage said fold line connection between said envelope and partition panels when said blank is formed into an interior partition.
Claim 2
Dependent Claim 142 words
A blank adapted to form an interior partition within a carton and an extensible handle member, said blank comprising a handle panel having a hand section and abutment flanges, a securing panel, a line of weakness connecting said handle panel to said securing panel to permit said handle panel to be torn therefrom, an envelope panel, a partition panel, said securing panel and said partition panel being connected to said envelope panel by substantially parallel fold lines positioned one on each end of said envelope panel and a handle opening along said fold line connection between said partition panel and said envelope panel, said opening permitting the handle section to be pulled through said opening into a carrying position wherein said flanges engage said fold line connection between said envelope and partition panels when said blank is formed into an interior partition.
Claim 3
Dependent Claim 78 words
A blank as defined in claim 1 further comprising a first bottom panel, a first side panel, a top panel, a second side panel and a second bottom panel foldably interconnected by a set of substantially parallel fold lines said first bottom panel being foldably connected by a fold line substantially parallel to said set of fold lines to the end of said partititon panel remote from said fold line connection between said envelope and said partition panels.
Claim 4
Dependent Claim 19 words
A blank as defined in claim 1 further comprising a handle reinforcing panel foldably connected to said handle Panel.
Claim 5
Dependent Claim 41 words
A blank as defined in claim 1 further comprising a handle reinforcing panel foldably connected to said handle panel by a fold line substantially parallel to said set of parallel fold lines and a spacer flap on said reinforcing handle panel.
Claim 6
Dependent Claim 67 words
A blank as defined in claim 4 wherein said flanges project laterally of said reinforcing handle panel, an aperture in said envelope panel, side edges of said aperture being spaced substantially the same distance as the spacing between end edges on said reinforcing panel, said side edges and said end edges being positioned to cooperate in the formed blank so that said edges function as guide surfaces.
Claim 7
Dependent Claim 202 words
A carton comprising means defined a top wall, bottom wall, side walls and end walls, and a longitudinally extending partition said partition including a partition panel, an envelope panel foldably connected to the end of said partition panel adjacent said top panel and positioned in spaced substantially parallel relationship with said partition panel, a securing panel foldably connected to the end of said envelope panel remote from its fold line connection to said partition panel, a handle panel having a handle section and abutment flanges, said handle panel connected to said securing panel via a line of weakness that may be broken when said handle is lifted to a carrying position, said securing panel and said handle panel being interposed between said envelope panel and said partition panel, means securing said securing panel to said partition panel, and a handle opening along said foldable connection between said partition panel and said envelope panel and means defining an access opening in said top walls through which said handle section may project when said handle is in a carrying position wherein said flanges engage said fold line connection between said envelope and said partition panels and means connecting said partition panel to said walls.
Claim 8
Dependent Claim 202 words
A carton comprising means defined a top wall, bottom wall, side walls and end walls, and a longitudinally extending partition said partition including a partition panel, an envelope panel foldably connected to the end of said partition panel adjacent said top panel and positioned in spaced substantially parallel relationship with said partition panel, a securing panel foldably connected to the end of said envelope panel remote from its fold line connection to said partition panel, a handle panel having a handle section and abutment flanges, said handle panel connected to said securing panel via a line of weakness that may be broken when said handle is lifted to a carrying position, said securing panel and said handle panel being interposed between said envelope panel and said partition panel, means securing said securing panel to said partition panel, and a handle opening along said foldable connection between said partition panel and said envelope panel and means defining an access opening in said top walls through which said handle section may project when said handle is in a carrying position wherein said flanges engage said fold line connection between said envelope and said partition panels and means connecting said partition panel to said walls.
Claim 9
Dependent Claim 30 words
A carton as defined in claim 6 wherein said means connecting said partition panel to said walls comprises a fold line integrally connecting said partition panel to said bottom panel.
Claim 10
Dependent Claim 23 words
A carton as defined in claim 7 further comprising tab means foldably connected to said partition panel and secured to said top wall.
Claim 11
Dependent Claim 27 words
A carton as defined in claim 6 further comprising a handle reinforcing panel secured in face-to-face relationship with said handle forming panel to form a reinforced handle.
Claim 12
Dependent Claim 48 words
A carton as defined in claim 9 wherein said handle reinforcing panel is narrower than said handle panel, guide surfaces on said partition adapted to cooperate with end edges of said handle reinforcing panel to guide said handle panel for movement between a retracted and said carrying position.
Claim 13
Dependent Claim 22 words
A carton as defined in claim 10 wherein said guide surfaces are lateral edges of an aperture formed in said envelope panel.
Claim 14
Dependent Claim 24 words
