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.

2 . The carton of claim 1 , wherein the base portion is positioned at an oblique angle relative to the intermediate portion.

3 . The carton of claim 2 , wherein the distal portion is positioned at an oblique angle relative to the intermediate portion.

4 . The carton of claim 3 , wherein the distal portion has a free edge that is in contact with the second side panel.

5 . 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.

6 . The carton of claim 5 , 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.

7 . The carton of claim 6 , 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.

8 . The carton of claim 3 , 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.
