Abstract

A carton for holding at least one article includes a plurality of panels that extends at least partially around an interior of the carton. The plurality of panels includes a front panel, a first side panel, a second side panel, and a back panel. A plurality of end flaps includes a first end flap foldably connected to the front panel and a second end flap foldably connected to the back panel. A first gusset is foldably connected to a portion of the first side panel and a second gusset is foldably connected to a portion of the second side panel. At least the first end flap, the first gusset, and the second gusset cooperate to form a first closure of the carton, and the second end flap forms a second closure of the carton. The second closure at least partially overlaps the first closure.

First claim

What is claimed is:

1 . A carton for holding at least one article, the carton comprising:
a plurality of panels that extends at least partially around an interior of the carton, the plurality of panels comprises a front panel, a first side panel, a second side panel, and a back panel; a plurality of end flaps foldably connected to respective panels of the plurality of panels, the plurality of end flaps comprises a first end flap foldably connected to the front panel and a second end flap foldably connected to the back panel; and a first gusset foldably connected to a portion of the first side panel and a second gusset foldably connected to a portion of the second side panel, at least the first end flap, the first gusset, and the second gusset cooperate to form a first closure of the carton, and the second end flap forms a second closure of the carton, the second closure at least partially overlaps the first closure.

2 . The carton of claim 1 , wherein the plurality of end flaps comprises a third end flap foldably connected to the first side panel and a fourth end flap foldably connected to the second side panel.

3 . The carton of claim 2 , wherein the first closure comprises the third end flap and the fourth end flap, the third and flap and the fourth end flap overlapping the first end flap.

4 . The carton of claim 3 , wherein the first closure provides a first seal at the top of the front panel, the first side panel, the second side panel, and the back panel, and the second closure at least partially envelops the first closure and provides a second seal at the top of the front panel, the first side panel, the second side panel, and the back panel.

5 . The carton of claim 1 , wherein the second end flap comprises a proximal portion foldably connected to a distal portion.

6 . The carton of claim 5 , wherein the proximal portion of the second end flap at least partially overlaps the first end flap, and the distal portion of the second end flap at least partially overlaps the front panel.

7 . The carton of claim 5 , wherein a portion of the first gusset is disposed inwardly toward the interior of the carton a first longitudinal distance, a portion of the second gusset is disposed inwardly toward the interior of the carton a second longitudinal distance, the first end flap has a length equal to a third longitudinal distance, and the front panel has a length equal to a fourth longitudinal distance, and the sum of the first longitudinal distance, the second longitudinal distance, and the third longitudinal distance is substantially equal to the fourth longitudinal distance.

8 . The carton of claim 1 , wherein an upper portion of the front panel is obliquely disposed relative to a lower portion of the front panel and an upper portion of the back panel is obliquely disposed relative to a lower portion of the back panel.

9 . The carton of claim 8 , wherein the second end flap comprises a proximal portion foldably connected to a distal portion, the distal portion of the second end flap is at least partially in face-to-face contact with the upper portion of the front panel.

10 . The carton of claim 1 , wherein the first gusset comprises a first gusset panel, a second gusset panel, and a third gusset panel.

11 . The carton of claim 10 , wherein the first gusset panel is foldably connected to each of the second gusset panel and the third gusset panel.

12 . The carton of claim 11 , wherein the first gusset panel is foldably connected to the second gusset panel by a first fold line having a first oblique portion intersecting a second oblique portion, and the first gusset panel is foldably connected to the third gusset panel by a second fold line having a first oblique portion and a second oblique portion.

13 . The carton of claim 12 , wherein the second oblique portion of the first fold line and the second oblique portion of the second fold line are interconnected by a curved fold line.

14 . The carton of claim 13 , wherein the second gusset comprises a fourth gusset panel, a fifth gusset panel, and a sixth gusset panel, the fourth gusset panel is foldably connected to the fifth gusset panel at a third fold line and the fourth gusset panel is foldably connected to the sixth gusset panel at a fourth fold line, each of the third fold line and the fourth fold line comprises a first oblique portion intersecting a second oblique portion, the second oblique portion of the third fold line and the second oblique portion of the fourth fold line are interconnected by a curved fold line.

15 . A blank for forming a carton for holding at least one article, the blank comprising:
a plurality of panels for extending at least partially around an interior of the carton formed from the blank, the plurality of panels comprises a front panel, a first side panel, a second side panel, and a back panel; a plurality of end flaps foldably connected to respective panels of the plurality of panels, the plurality of end flaps comprises a first end flap foldably connected to the front panel and a second end flap foldably connected to the back panel; and a first gusset foldably connected to a portion of the first side panel and a second gusset foldably connected to a portion of the second side panel, at least the first end flap, the first gusset, and the second gusset are for cooperating to form a first closure of the carton formed from the blank, and the second end flap is for forming a second closure of the carton formed from the blank, the second closure is for at least partially overlapping the first closure of the carton formed from the blank.

16 . The blank of claim 15 , wherein the plurality of end flaps comprises a third end flap foldably connected to the first side panel and a fourth end flap foldably connected to the second side panel.

17 . The blank of claim 16 , wherein the first closure comprises the third end flap and the fourth end flap when the carton is formed from the blank, the third and flap and the fourth end flap overlapping the first end flap when the carton is formed from the blank.

18 . The blank of claim 17 , wherein the first closure provides a first seal at the top of the front panel, the first side panel, the second side panel, and the back panel, and the second closure at least partially envelops the first closure and provides a second seal at the top of the front panel, the first side panel, the second side panel, and the back panel when the carton is formed from the blank.

19 . The blank of claim 15 , wherein the second end flap comprises a proximal portion foldably connected to a distal portion.
