CONTAINER HAVING AN AUTOMATICALLY LOCKING BOTTOM AND BLANKS FOR MAKING THE SAME
First Claim
1. A blank of sheet material for forming a container including automatically locking bottom panels, said blank comprising:
- a pair of end panels, a pair of side panels and at least one corner panel interconnected to form a pair of opposing end walls, a pair of opposing side walls and a corner wall of the container, said at least one corner panel extending between an adjacent end panel and side panel;
a plurality of bottom panels for forming a bottom wall of the container, said bottom panels comprising a pair of bottom end panels each extending from a bottom edge of each of said pair of end panels, and a pair of bottom side panels each extending from a bottom edge of said pair of side panels;
a first coupling tab integral with one of said pair of bottom end panels; and
a second coupling tab integral with one of said pair of bottom side panels,wherein said first coupling tab attaches to one of said pair of bottom side panels, and said second coupling tab attaches to one of said pair of bottom end panels, said coupling tabs configured to upwardly direct said bottom panels when the container is moved from an erected position to a knocked-down flat position and downwardly direct said bottom panels when the container is moved from a knocked-down flat position to an erected position.

Abstract
A blank of sheet material for forming a container including automatically locking bottom panels is provided. The blank includes a pair of end panels, a pair of side panels and at least one corner panel that are interconnected. The corner panel extends between an adjacent end panel and side panel. The blank includes bottom end panels extending from the end panels and bottom side panels extending from the side panels. A first coupling tab is integral with a bottom end panel, and a second coupling tab is integral with a bottom side panel. The first coupling tab attaches to a bottom side panel, and the second coupling tab attaches to a bottom end panel. The coupling tabs upwardly direct the bottom panels when the container is moved to a flat position and downwardly direct the bottom panels when the container is moved from the flat position to an erected position.

25. A method of forming a container from a blank of sheet material, the blank including a pair of glue flaps, a pair of end panels, a pair of side panels, and at least one corner panel connected in series along a plurality of fold lines, said method comprising:
-
rotating the side panels, end panels, and the at least one corner panel about respective fold lines toward an interior surface of the blank; coupling a first glue flap to a second glue flap to form a pair of side walls, a pair of end walls, and at least two corner walls, wherein a first corner wall includes the first and second glue flaps; rotating a first major bottom panel about a fold line toward an interior surface of a first side wall; rotating a first minor bottom panel about a fold line toward an interior surface of a first end wall, an interior surface of the first minor bottom panel contacting an exterior surface of the first major bottom panel; rotating a second major bottom panel about a fold line toward an interior surface of a second side wall, an interior surface of the second major bottom panel contacting exterior surfaces of the first major and minor bottom panels; securing a coupling tab of the second major bottom panel to the first minor bottom panel; rotating a second minor bottom panel about a fold line toward an interior surface of a second end wall, an interior surface of the second minor bottom panel contacting exterior surfaces of the major bottom panels; and securing a coupling tab of the second minor bottom panel to the first major bottom panel. - View Dependent Claims (26, 27, 28, 29, 30)
