Abstract

A carton defines a bottom wall, a first side wall coupled to the bottom wall, a second side wall disposed opposite the first side wall and coupled to the bottom wall, a first end wall coupled to both the bottom wall and first and second side walls, and a second end wall disposed opposite the first end wall and coupled to both the bottom wall and the first and second side walls. The carton is formed from a blank having a first side and a second side disposed opposite said first side. The first side defines the interior surface of the bottom wall and the interior and exterior surfaces of the first and second side walls and the first and second end walls.

First claim

1 . A carton for containing a plurality of articles, the carton comprising:
a bottom wall, a first side wall coupled to the bottom wall, a second side wall disposed opposite the first side wall and coupled to the bottom wall, a first end wall coupled to both the bottom wall and the first and second side walls, and a second end wall disposed opposite the first end wall and coupled to both the bottom wall and the first and second side walls; wherein each of the bottom wall, the first and second side walls, and the first and second end walls define both an interior surface disposed adjacent an interior space defined by the carton and an exterior surface; wherein the carton is formed from a blank comprising a first side and a second side disposed on a side of said blank opposed to said first side; and wherein the interior surface of said bottom wall, and the interior and exterior surfaces of the first and second side walls and first and second end walls are each defined by said first side.

2 . The carton of claim 1 , wherein said first side is a treated side and said second side is an untreated side, said treated side having received one or more surface treatments, said untreated side not having received said one or more surface treatments.

3 . The carton of claim 2 , wherein said one or more surface treatments comprises printing.

4 . The carton of claim 2 , wherein said one or more surface treatments comprises application of a water resistant coating.

5 . The carton of claim 1 , wherein the interior surfaces of said first and second end walls are each substantially smooth and uninterrupted by folded edges.

6 . The carton of claim 5 , wherein the interior surfaces of said first and second side walls and the interior surface of said bottom wall are each substantially smooth and uninterrupted by folded edges.

7 . The carton of claim 1 , wherein said blank comprises a plurality of main panels hinged together in a linear series, said plurality of main panels comprising first and second inner side panels, first and second outer side panels, and a bottom panel;
wherein said first outer side panel is hingedly connected to said first inner side panel, said first inner side panel is hingedly connected to said bottom panel, said bottom panel is hingedly connected to said second inner side panel, and said second inner side panel is hingedly connected to said second outer side panel; wherein said first outer side panel defines the exterior surface of said first side wall, said first inner side panel defines the interior surface of said first side wall, said bottom panel defines the exterior and interior surfaces of said bottom wall, said second inner side panel defines the interior surface of said second side wall, and said second outer side panel defines the exterior surface of said second side wall.

8 . The carton of claim 7 , wherein said blank further comprises first and second end panels hingedly connected to said bottom panel at respective opposite ends of said bottom panel, wherein said first end panel defines the interior surface of said first end wall and wherein said second end panel defines the interior surface of said second end wall.

9 . The carton of claim 8 , wherein said blank further comprises first and second outer end flaps hingedly connected to said first outer side panel at respective opposite ends of said first outer side panel, and third and fourth outer end flaps hingedly connected to said second outer side panel at respective opposite ends of said second outer side panel;
wherein said first and third outer end flaps define the exterior surface of said first end wall and the second and fourth outer end flaps define the exterior surface of said second end wall.

10 . The carton of claim 9 , wherein said blank further comprises first and second inner end flaps hingedly connected to said first inner side panel at respective opposite ends of said first inner side panel, and third and fourth inner end flaps hingedly connected to said second inner side panel at respective opposite ends of said second inner side panel.

11 . The carton of claim 10 , wherein said blank defines a plurality of inner end flap apertures, each of the plurality of inner end flap apertures being disposed along a central length of a fold line disposed between one of said first, second, third, or fourth inner end flaps and a respective one of said first or second inner side panels.

12 . The carton of claim 1 , wherein said first and second end walls define respective first and second handle structures.

13 . The carton of claim 12 , wherein said first handle structure comprises a first handle aperture disposed on the exterior of the first end wall, wherein said first handle aperture does not extend completely through said first end wall, wherein said second handle structure comprises a second handle aperture disposed on the exterior surface of the second end wall, wherein said second handle aperture does not extend completely through the second end wall.

14 . The carton of claim 1 , wherein said first side wall defines at least one first stacking tab that projects from an upper edge of said first side wall, wherein said second side wall defines at least one second stacking tab that projects from an upper edge of said second side wall.

15 . The carton of claim 14 , wherein said at least one first stacking tab comprises a first folding tab that projects from an upper edge of the interior surface of said first side wall and is folded back onto the exterior surface of said first side wall, and wherein said at least one second stacking tab comprises a second folding tab that projects from an upper edge of the interior surface of said second side wall and is folded back onto the exterior surface of said second side wall.

16 . The carton of claim 14 , wherein said carton defines at least one first side aperture and at least one second side aperture, said at least one first side aperture being defined in part by both said bottom wall and said first side wall, said at least one second side aperture being defined in part by both said bottom wall and said second side wall, each of said at least one first side aperture and said at least one second aperture being configured to receive a stacking tab of a second carton.

17 . The carton of claim 14 , wherein said carton defines at least one first end aperture and at least one second end aperture, said at least one first end aperture being defined in part by both said bottom wall and said first end wall, said at least one second end aperture being defined in part by both said bottom wall and said second end wall.

18 . A blank for forming a carton, the blank comprising:
a first side; a second side disposed on a side of said blank opposed to said first side, and a plurality of panels and flaps, the plurality of panels and flaps configured to form a set-up carton defining a bottom wall, a first side wall coupled to the bottom wall, a second side wall disposed opposite the first side wall and coupled to the bottom wall, a first end wall coupled to both the bottom wall and the first and second side walls, and a second end wall disposed opposite the first end wall and coupled to both the bottom wall and the first and second side walls; wherein each of the bottom wall, the first and second side walls, and the first and second end walls define both an interior surface disposed adjacent an interior space defined by the set-up carton and an exterior surface; wherein the interior surface of said bottom wall, and the interior and exterior surface
