Abstract

A carton for holding a plurality of articles. The carton includes at least one top panel, a first side panel, a second side panel, and a bottom panel. A plurality of end flaps is foldably connected to a respective panel to close an end of the carton. The carton includes reinforcement features at the end of the carton to increase the strength of the carton.

First claim

What is claimed is:

1. A carton for carrying a plurality of articles, the carton comprising:
a plurality of panels that extend at least partially around an interior of the carton, the plurality of panels comprising at least one top panel, a first side panel, a second side panel, and bottom panel;
a plurality of end flaps each foldably connected to a respective panel of the plurality of panels for closing an end of the carton,
wherein at least one end flap of the plurality of end flaps has reinforcement features for increasing the strength of the carton, the reinforcement features comprising a base portion foldably connected to the first side panel, an intermediate portion foldably connected to the base portion, and a distal portion foldably connected to the intermediate portion, the distal portion extending from the intermediate portion to a free edge of the distal portion;
wherein each of the base portion and the distal portion is positioned at an oblique angle relative to the intermediate portion, and the distal portion extends from the intermediate portion toward the second side panel.

2. The carton of claim 1 , wherein the free edge of the distal portion is in contact with the second side panel.

3. The carton of claim 1 , wherein the at least one end flap is a first side end flap foldably connected to the first side panel, the plurality of end flaps comprises a top end flap foldably connected to the at least one top panel, and the intermediate portion is in face-to-face contact with the top end flap.

4. The carton of claim 3 , wherein the plurality of end flaps comprises a bottom end flap foldably connected to the bottom panel, and the intermediate portion is in face-to-face contact with the bottom end flap.

5. The carton of claim 4 , wherein the at least one top panel comprises a first oblique edge, the bottom panel comprises a second oblique edge, and the base portion of the first side end flap conforms to the first oblique edge and second oblique edge to form a corner of the carton.

6. The carton of claim 1 , wherein the at least one end flap is a first side end flap foldably connected to the first side panel, and the plurality of end flaps comprises a second side end flap foldably connected to the second side panel, and wherein the second side end flap is in face-to-face contact with the intermediate portion of the first side end flap.

7. The carton of claim 6 , wherein the second side end flap forms an external corner of the carton, the external corner being spaced apart from the distal portion of the first side end flap, and wherein the first side end flap is internal to the second side end flap.

8. The carton of claim 1 , wherein the plurality of end flaps is a first plurality of end flaps at a first end of the carton, the carton further comprises a second plurality of end flaps at a second end of the carton, the reinforcement features are first reinforcement features, and the carton comprises second reinforcement features in at least one end flap of the second plurality of end flaps.

9. The carton of claim 8 , wherein the second reinforcement features of the at least one end flap of the second plurality of end flaps comprises a base portion foldably connected to the first side panel, an intermediate portion foldably connected to the base portion, and a distal portion foldably connected to the intermediate portion.

10. The carton of claim 1 , further comprising a handle, the handle comprising at least one handle flap foldably connected to the at least one top panel.

11. The carton of claim 1 , wherein the free edge is a first free edge, the distal portion comprises a second free edge and a third free edge extending from respective ends of the first free edge, and the second free edge contacts an inner face of the top panel, and the third free edge contacts an inner face of the bottom panel.

12. A blank for forming a carton for carrying a plurality of articles, the blank comprising:
a plurality of panels comprising at least one top panel, a first side panel, a second side panel, and bottom panel;
a plurality of end flaps each foldably connected to a respective panel of the plurality of panels for closing an end of the carton formed from the blank,
at least one end flap of the plurality of end flaps has reinforcement features for increasing the strength of the carton formed from the blank, the reinforcement features comprising a base portion foldably connected to the first side panel, an intermediate portion foldably connected to the base portion, and a distal portion foldably connected to the intermediate portion, the distal portion extending from the intermediate portion to a free edge of the distal portion;
wherein each of the base portion and the distal portion is positioned at an oblique angle relative to the intermediate portion when the carton is formed from the blank, and the distal portion extends from the intermediate portion toward the second side panel when the carton is formed from the blank.

13. The blank of claim 12 , wherein the free edge of the distal portion is in contact with the second side panel when the carton is formed from the blank.

14. The blank of claim 12 , wherein the at least one end flap is a first side end flap foldably connected to the first side panel, the plurality of end flaps comprises a top end flap foldably connected to the at least one top panel, and the intermediate portion is in face-to-face contact with the top end flap when the carton is formed from the blank.

15. The blank of claim 14 , wherein the plurality of end flaps comprises a bottom end flap foldably connected to the bottom panel, and the intermediate portion is in face-to-face contact with the bottom end flap when the carton is formed from the blank.

16. The blank of claim 15 , wherein the at least one top panel comprises a first oblique edge, the bottom panel comprises a second oblique edge, and the base portion of the first side end flap conforms to the first oblique edge and second oblique edge to form a corner of the carton when the carton is formed from the blank.

17. The blank of claim 12 , wherein the at least one end flap is a first side end flap foldably connected to the first side panel, the plurality of end flaps comprises a second side end flap foldably connected to the second side panel, and the second side end flap is in face-to-face contact with the intermediate portion of the first side end flap when the carton is formed from the blank.

18. The blank of claim 17 , wherein the second side end flap forms an external corner of the carton when the carton is formed from the blank, the external corner is spaced apart from the distal portion of the first side end flap when the carton is formed from the blank, and the first side end flap is internal to the second side end flap when the carton is formed from the blank.

19. The blank of claim 12 , wherein the plurality of end flaps is a first plurality of end flaps at a first end of the blank, the blank further comprises a second plurality of end flaps at a second end of the blank, the reinforcement features are first reinforcement features, and the blank further comprises second reinforcement features in at least one end flap of the second plurality of end flaps.

20. The blank of claim 19 , wherein the second reinforcement features of the at least one end flap of the second plurality of end flaps comprises a base portion foldably connected to the first side panel, an intermediate portion foldably connected to the base portion, and a distal portion foldably co
