Abstract

A carton for holding at least one food product includes a plurality of panels at least partially extending around an interior of the carton, the plurality of panels including a bottom panel, at least one side panel, at least one end panel, and an access panel. The carton further includes a plurality of end flaps foldably connected to a respective panel of the plurality of panels, the plurality of end flaps including a lid flap foldably connected to a respective panel of the plurality of panels for forming a closed end of the carton. The carton further includes leak-resistant features including a downwardly sloping arrangement of the at least one side panel and the at least one end panel toward the bottom panel to form a bottom receptacle for one or more fluids in the interior of the carton.

First claim

What is claimed is:

1. A carton for holding at least one food product, the carton comprising:
a plurality of panels at least partially extending around an interior of the carton, the plurality of panels including a bottom panel, a first end panel foldably connected to the bottom panel, a second end panel foldably connected to the bottom panel, a first side panel foldably connected to the bottom panel, a second side panel foldably connected to the bottom panel, and an access panel, the first end panel foldably connected to the first side panel, the first side panel foldably connected to the second end panel, the second end panel foldably connected to the second side panel, and the second side panel foldably connected to the first end panel;
a plurality of end flaps foldably connected to a respective panel of the plurality of panels, the plurality of end flaps comprising a lid flap foldably connected to a respective panel of the plurality of panels for forming a closed end of the carton; and
leak-resistant features including a downwardly sloping arrangement of the first end panel, the second end panel, the first side panel, and the second side panel toward the bottom panel to form a bottom receptacle for one or more fluids in the interior of the carton.

2. The carton of claim 1 , wherein each of the first end panel, the second end panel, the first side panel, and the second side panel are obliquely arranged relative to the bottom panel.

3. The carton of claim 2 , wherein the bottom panel has a flat profile providing a base for supporting the carton on a supporting surface in a stable arrangement.

4. The carton of claim 2 , wherein the access panel comprises a base portion and a distal portion foldably connected to the base portion, the distal portion at least partially separable from the remainder of the carton to provide access to the interior of the carton.

5. The carton of claim 4 , wherein the plurality of end flaps comprises at least one attachment flap foldably connected to the access panel, the distal portion of the access panel is at least partially separable from the at least one attachment flap.

6. The carton of claim 5 , wherein the plurality of end flaps further comprises at least one locking flap foldably connected to the first side panel and attached to the at least one attachment flap.

7. The carton of claim 6 , wherein the carton further comprises locking features for maintaining a closed configuration of the carton.

8. The carton of claim 7 , wherein the locking features comprise a notch formed along the at least one locking flap for at least partially receiving a portion of the lid flap.

9. The carton of claim 8 , wherein the notch is at least partially defined by an extension of the at least one locking flap, the extension protruding past the remainder of the at least one locking flap.

10. The carton of claim 9 , wherein the at least one locking flap is a first locking flap foldably connected to the first side panel, the plurality of end flaps further comprises a second locking flap foldably connected to the second side panel, the notch is a first notch formed along the first locking flap, the extension is a first extension at least partially defining the first notch, and the locking features further comprise a second notch formed along the second locking flap for at least partially receiving a portion of the lid flap and a second extension protruding past the remainder of the second locking flap and at least partially defining the second notch.

11. A blank for forming a carton for holding at least one food product, the blank comprising:
a plurality of panels comprising a bottom panel, a first end panel foldably connected to the bottom panel, a second end panel foldably connected to the bottom panel, a first side panel foldably connected to the bottom panel, a second side panel foldably connected to the bottom panel, and an access panel, the first end panel foldably connected to the first side panel, the first side panel foldably connected to the second end panel, the second end panel foldably connected to the second side panel, and the second side panel foldably connected to the first end panel;
a plurality of end flaps foldably connected to a respective panel of the plurality of panels, the plurality of end flaps comprising a lid flap foldably connected to a respective panel of the plurality of panels for forming a closed end of the carton formed from the blank,
the first end panel, the second end panel, the first side panel, the second side panel, and the bottom panel are for forming leak-resistant features of the carton formed from the blank including a downwardly sloping arrangement of the first end panel, the second end panel, the first side panel, the second side panel toward the bottom panel to form a bottom receptacle for one or more fluids in the interior of the carton formed from the blank.

12. The blank of claim 11 , wherein the access panel comprises a base portion and a distal portion foldably connected to the base portion, the distal portion at least partially separable from the remainder of the blank to provide access to the interior of the carton formed from the blank.

13. The blank of claim 12 , wherein the plurality of end flaps comprises at least one attachment flap foldably connected to the access panel, the distal portion of the access panel is at least partially separable from the at least one attachment flap.

14. The blank of claim 13 , wherein the plurality of end flaps further comprises at least one locking flap foldably connected to the first side panel and for being attached to the at least one attachment flap when the carton is formed from the blank.

15. The blank of claim 14 , wherein the blank further comprises locking features for maintaining a closed configuration of the carton formed from the blank.

16. The blank of claim 15 , wherein the locking features comprise a notch formed along the at least one locking flap for at least partially receiving a portion of the lid flap when the carton is formed from the blank.

17. The blank of claim 16 , wherein the notch is at least partially defined by an extension of the at least one locking flap, the extension protruding past the remainder of the at least one locking flap.

18. The blank of claim 17 , wherein the at least one locking flap is a first locking flap foldably connected to the first side panel, the plurality of end flaps further comprises a second locking flap foldably connected to the second side panel, the notch is a first notch formed along the first locking flap, the extension is a first extension at least partially defining the first notch, and the locking features further comprise a second notch formed along the second locking flap for at least partially receiving a portion of the lid flap when the carton is formed from the blank and a second extension protruding past the remainder of the second locking flap and at least partially defining the second notch.

19. A method of forming a carton for holding at least one food product, the method comprising:
obtaining a blank comprising a plurality of panels and a plurality of end flaps foldably connected to a respective panel of the plurality of panels, the plurality of panels comprising a bottom panel, a first end panel foldably connected to the bottom panel, a second end panel foldably connected to the bottom panel, a first side panel foldably connected to the bottom panel, a second side panel foldably connected to the bottom panel, and an access panel, the first end panel foldably connected to the f
