Abstract

A reinforced box includes a body board including a first material, the body board including a bottom panel defining a first bottom side and a second bottom side, the first bottom side positioned opposite from the second bottom side; a first side panel hingedly attached to the first bottom side of the bottom panel; and a second side panel hingedly attached to the second bottom side of the bottom panel; and an end panel including a second material, the second material being different from the first material, the end panel attached to the first side panel and the second side panel.

First claim

That which is claimed is:

1. A reinforced box comprising:
a body board comprising a first material, the body board comprising:
a bottom panel defining a first bottom side and a second bottom side, the first bottom side positioned opposite from the second bottom side;
a first side panel hingedly attached to the first bottom side of the bottom panel; and
a second side panel hingedly attached to the second bottom side of the bottom panel; and

an end panel comprising a second material, the second material being different from the first material, a first portion of the end panel attached to the first side panel, a second portion of the end panel attached to the second side panel, at least one end fold line defined between the first portion and the second portion; and
wherein the reinforced box is selectively reconfigurable from a collapsed configuration to an open configuration, the first portion folded relative to the second portion about the at least one end fold line in the collapsed configuration, the first portion and the second portion of the end panel positioned perpendicular with the first side panel and the second side panel in the open configuration.

2. The reinforced box of claim 1 , wherein:
the first material defines a first thickness;
the second material defines a second thickness; and
the second thickness is larger than the first thickness.

3. The reinforced box of claim 1 , wherein:
the first material is lightweight cardboard; and
the second material is heavyweight cardboard.

4. The reinforced box of claim 1 , wherein:
the end panel is a first end panel;
the reinforced box comprises a second end panel positioned opposite from the first end panel;
the second end panel comprises the second material; and
the second end panel is attached to the first side panel and the second side panel.

5. The reinforced box of claim 1 , wherein:
the first side panel comprises a side flap; and
the side flap is attached to the end panel.

6. The reinforced box of claim 5 , wherein the side flap is attached to the end panel with an adhesive.

7. The reinforced box of claim 1 , wherein:
the body board further comprises an end flap hingedly attached to an end of the bottom panel;
the end extends between the first bottom side and the second bottom side; and
the end flap is attached to the end panel.

8. The reinforced box of claim 7 , wherein:
the end flap is a first end flap;
the body board further comprises a second end flap hingedly attached to the end of the bottom panel;
the second end flap is attached to the end panel;
an end flap notch is defined between the first end flap and the second end flap; and
the end flap notch is configured to provide clearance for the bottom panel to collapse.

9. A method of assembling a reinforced box, the method comprising:
folding a first side panel about a first side hinge relative to a bottom panel;
folding a second side panel about a second side hinge relative to the bottom panel, the first side panel, the second side panel, and the bottom panel comprised by a body board of the reinforced box, the body board comprising a first material;
attaching a first portion of a first end panel to the first side panel and a second portion of the first end panel to the second side panel, at least one end fold line defined between the first portion and the second portion, the first end panel comprising a second material, the second material being different from the first material;
attaching a second end panel to the first side panel and the second side panel, the second end panel comprising the second material; and
collapsing the reinforced box from an open configuration to a collapsed configuration comprising folding the first portion relative to the second portion about the at least one end fold line.

10. The method of claim 9 , wherein:
the first material defines a first thickness;
the second material defines a second thickness; and
the second thickness is larger than the first thickness.

11. The method of claim 9 , wherein:
the first side panel comprises a first side flap and a second side flap;
attaching the first end panel to the first side panel comprises attaching the first side flap to the first end panel; and
attaching the second end panel to the first side panel comprises attaching the second side flap to the first end panel.

12. The method of claim 11 , wherein attaching the first side flap to the first end panel comprises adhering the first side flap to the first end panel.

13. The method of claim 11 , wherein the first side flap and the second side flap are hingedly connected to the first side panel.

14. The method of claim 9 , further comprising attaching an end flap of the body board to the first end panel, the end flap hingedly attached to the bottom panel.

15. The method of claim 14 , wherein the end flap is a first end flap, and wherein the method further comprises attaching a second end flap of the body board to the first end panel, the second end flap hingedly attached to the bottom panel.

16. The method of claim 15 , wherein an end flap notch is defined between the first end flap and the second end flap; and wherein the end flap notch provides clearance for the bottom panel to collapse.

17. The method of claim 9 , wherein:
the body board further comprises a first top flap hingedly attached to the first side panel by a first top flap hinge and a second top flap hingedly attached to the second side panel by a second top flap hinge; and
the method further comprises:
folding the first top flap about the first top flap hinge;
folding the second top flap about the second top flap hinge; and
engaging the first top flap with the second top flap.

18. The method of claim 17 , wherein engaging the first top flap with the second top flap comprises interlocking a first top notch with a second top notch, the first top notch defined by a first top flap end of the first top flap, the second top notch defined by a second top flap end of the second top flap.
