Abstract

Abstract A carton having a plurality of unequal compartments or cells is formed from a single, unitary, paperboard blank. The carton can be folded flat for shipping and storage. It can be erected by pulling outward on two opposite corners or side edges. Internal dividers move into place automatically as the box is erected and produce internal compartments of unequal sizes.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 424 words
A paperboard carton having a plurality of internal cells of varying size, said carton comprising: (a) a front wall panel; (b) a rear wall panel; (c) a pair of side wall panels; (d) said front, rear and side wall panels being foldably connected together in series to form sides for said carton; (e) a first bottom wall panel foldably connected to said front wall panel; (f) a second bottom wall panel foldably connected to one of said side wall panels; (g) a third bottom wall panel foldably connected to said rear wall panel; (h) a fourth bottom wall panel foldably connected to the other of said side wall panels; (i) a first divider panel foldably connected to one of said first and third bottom wall panels; (j) a second divider panel foldably connected to said first divider panel, said second divider panel being foldably connected to a first triangular glue panel which is also foldably connected to said one of said first and third bottom wall panels, said first triangular glue panel providing a foldable connection between said first and second bottom wall panels; (k) a third divider panel foldably connected to the other of said first and third bottom wall panels and disposed adjacent to said first divider panel, said third divider panel including an upwardly projecting handle portion; (l) means forming a hand grip opening in said handle portion; (m) a fourth divider panel foldably connected to said third divider panel along a fold line which is laterally offset from a vertical midline of said third divider panel and from said hand grip opening so that an imaginary extension of said fold line does not pass through said hand grip opening; (n) a fifth divider panel foldably connected to said fourth bottom wall panel, said fifth divider panel lying adjacent to said fourth divider panel; (o) a second triangular glue panel foldably connected to said other of said first and third bottom wall panels and free of connection with said third divider panel, said second triangular glue panel being operable to provide a foldable connection between said third and fourth bottom wall panels; and (p) said first divider panel and said third divider panel being operable to divide said carton interior into two substantially equal compartments between said front wall panel and said rear wall panel, said second divider panel being operable to divide one of said compartments into substantially equal cells, and said fourth and fifth divider panels being operable to divide the other of said compartments into substantially unequal cells.
Claim 2
Dependent Claim 424 words
A paperboard carton having a plurality of internal cells of varying size, said carton comprising: (a) a front wall panel; (b) a rear wall panel; (c) a pair of side wall panels; (d) said front, rear and side wall panels being foldably connected together in series to form sides for said carton; (e) a first bottom wall panel foldably connected to said front wall panel; (f) a second bottom wall panel foldably connected to one of said side wall panels; (g) a third bottom wall panel foldably connected to said rear wall panel; (h) a fourth bottom wall panel foldably connected to the other of said side wall panels; (i) a first divider panel foldably connected to one of said first and third bottom wall panels; (j) a second divider panel foldably connected to said first divider panel, said second divider panel being foldably connected to a first triangular glue panel which is also foldably connected to said one of said first and third bottom wall panels, said first triangular glue panel providing a foldable connection between said first and second bottom wall panels; (k) a third divider panel foldably connected to the other of said first and third bottom wall panels and disposed adjacent to said first divider panel, said third divider panel including an upwardly projecting handle portion; (l) means forming a hand grip opening in said handle portion; (m) a fourth divider panel foldably connected to said third divider panel along a fold line which is laterally offset from a vertical midline of said third divider panel and from said hand grip opening so that an imaginary extension of said fold line does not pass through said hand grip opening; (n) a fifth divider panel foldably connected to said fourth bottom wall panel, said fifth divider panel lying adjacent to said fourth divider panel; (o) a second triangular glue panel foldably connected to said other of said first and third bottom wall panels and free of connection with said third divider panel, said second triangular glue panel being operable to provide a foldable connection between said third and fourth bottom wall panels; and (p) said first divider panel and said third divider panel being operable to divide said carton interior into two substantially equal compartments between said front wall panel and said rear wall panel, said second divider panel being operable to divide one of said compartments into substantially equal cells, and said fourth and fifth divider panels being operable to divide the other of said compartments into substantially unequal cells.
Claim 3
Dependent Claim 41 words
The carton of claim 1 further comprising a cover panel foldably connected to one of said front and rear panels, said cover panel including a slot through which said handle portion projects when said cover panel is in a closed position.
