Abstract
A blank of sheet material for forming a container is provided. The blank includes a series of four generally rectangular panels connected along a plurality of substantially parallel fold lines. The panels include a first spaced-apart pair of panels and a second spaced-apart pair of panels. Each of the second spaced-apart pair of panels is connected to at least one panel of the first spaced-apart pair of panels. The blank also includes a corner panel extending from each side edge of each panel of the first pair of panels, and a lateral flap extending from each side edge of each panel of the second pair of panels, wherein each lateral flap has free side edges.

A blank of sheet material for forming a container having a cavity, said blank comprising:
- a series of three panels connected along a plurality of substantially parallel fold lines, said panels comprising a front panel, a bottom panel and a rear panel, said front and rear panels configured to form a front side wall and an opposing rear side wall respectively when the container is formed, and said bottom panel configured to form a bottom wall of the container when the container is formed;
- a corner panel extending from each side edge of each of said front and rear panels;
- a side panel extending from each side edge of each said corner panel such that each said corner panel extends between one of said front and rear panels and one of said side panels;
- a plurality of bifold panels, a respective bifold panel of said plurality of bifold panels extending from each side edge of each side panel such that each said side panel extends between one of said corner panels and one of said bifold panels, each bifold panel having at least two subpanels connected by a fold, wherein each one of said bifold panels is configured to overlap an adjacent one of said bifold panels when the container is formed;
- and
- a lateral flap extending from each side edge of said bottom panel, each said lateral flap configured to be coupled to a pair of adjacent side panels for forming the container.
A container formed from a blank of sheet material, said container comprising a bottom wall, a pair of end walls, a pair of side walls, and at least one corner wall interconnected along a plurality of fold lines to define a cavity of said container, said at least one corner wall extending between a first end wall of said pair of end walls and a first side wall of said pair of side walls to partially define the cavity, said first side wall comprises a first side panel, a first bifold panel emanating from said first side panel along a first fold line, a second side panel, and a second bifold panel emanating from said second side panel along a second fold line, each bifold panel comprise of at least two subpanels connected by a fold line, said first bifold panel and said second bifold panel overlapping one another.
A method of forming a container from a blank of sheet material, the blank including a series of three panels connected along a plurality of substantially parallel fold lines, said panels comprising a front panel, a bottom panel and a rear panel, a corner panel extending from each side edge of each of the front and rear panels, a side panel extending from each side edge of each corner panel such that each corner panel extends between one of the front and rear panels and one of the side panels, a joinder panel extending from each side edge of each side panel such that each said side panel extends between one of said corner panels and one of said joinder panels, each joinder panel having a free edge, and a lateral flap extending from each side edge of the bottom panel, said method comprising:
- rotating the front panel and the bottom panel about respective fold lines toward an interior surface of the bottom panel to form a pair of opposing end walls and a bottom wall;
- rotating each corner panel about a respective fold line toward a corresponding adjacent one of the front and rear panels to form a plurality of corner walls;
- rotating each side panel about a respective fold line toward a corresponding adjacent one of the corner panels;
- rotating each joinder panel about a respective fold line toward a corresponding adjacent one of the side panels such that the free edge of each joinder panel engages the free edge of a corresponding adjacent joinder panel;
- rotating each lateral flap about a respective fold line toward at least one corresponding side panel;
- and securing each lateral flap to the at least one corresponding side panel to form a pair of opposing side walls, wherein the bottom wall, the pair of end walls, the plurality of corner walls, and the pair of side walls define a cavity of the container.
