Triangular shipping container

A triangular shipping container that is a flat surface when unassembled, comprising:

• a first board;
• a second board that is foldably connected to the first board along a first fold line;
• a third board that is foldably connected to the second board along a second fold line;
• a first foldable wing flap near a first end of the first fold line, the first foldable wing flap including a first portion of the first board and a second portion of the second board, the first portion and the second portion being symmetric about the first fold line;
• and
• a second foldable wing flap near a second end of the first fold line, the second end being opposite to the first end, the second foldable wing flap including a third portion that is formed from the first board and a fourth portion that is formed from the second board, the third portion and the fourth portion being symmetric about the first fold line, wherein when the flat surface is folded at the first fold line and the second fold line:
• at least two of the first board, the second board and the third board fold at the first fold line and the second fold line to form the triangular shipping container,
• a specified portion of the first fold line about which the first portion and the second portion are symmetric is perpendicular to the first fold line, and
• wherein the specified portion of the first fold line, a first side of the first portion and a second side of the second portion that form a vertex on the first fold line are perforated to enable folding, and wherein at least two of the first side, the second side and the specified portion of the first fold line are perforated with different sizes of perforations.

A planar material to be assembled into a container, comprising:

• a first trapezoidal portion, the first trapezoidal portion including:
• a first foldable line and a second foldable line that are parallel to a long edge of the first trapezoidal portion,
• a first pair of perforated lines extending from a first pair of points on a first short edge of the first trapezoidal portion and converging at the first foldable line forming a first vertex, each point of the first pair of points being on a different side of the first foldable line, wherein the first pair of perforated lines form a pair of triangular shaped portions on the first trapezoidal portion, the pair of triangular shaped portions sharing a portion of the first foldable line as a common side, and
• a second pair of perforated lines extending from a second pair of points on a second short edge of the first trapezoidal portion and converging at the first foldable line to form a second vertex, each point of the second pair of points being on different sides of the first foldable line,
• wherein the planar material is configured to form the container when the first trapezoidal portion is folded at the first foldable lines, the second foldable line, the first pair of perforated lines and the second pair of perforated lines, wherein, when the first trapezoidal portion is folded at the first foldable line, the common side is perpendicular to the first foldable line, and
• wherein the common side and the first pair of perforated lines are perforated with different sizes of perforations.

A method for making a planar material that is configured to be assembled into a container, the method comprising:

• forming, in a first trapezoidal portion of the planar material, a first foldable line and a second foldable line that are parallel to a long edge of the first trapezoidal portion;
• forming, in the first trapezoidal portion, a first pair of perforated lines that extend from a first pair of points on a first short edge of the first trapezoidal portion and converging at the first foldable line forming a first vertex, each point of the first pair of points being on a different side of the first foldable line, wherein the first pair of perforated lines form a pair of triangular shaped portions on the first trapezoidal portion, the pair of triangular shaped portions sharing a portion of the first foldable line as a common side;
• and
• forming, in the first trapezoidal portion, a second pair of perforated lines that extend from a second pair of points on a second short edge of the first trapezoidal portion and converging at the first foldable line to form a second vertex, each point of the second pair of points being on different sides of the first foldable line, wherein the planar material is configured to form the container when the first trapezoidal portion is folded at the first foldable lines, the second foldable line, the first pair of perforated lines and the second pair of perforated lines, wherein, when the first trapezoidal portion is folded at the first foldable line, the common side is perpendicular to the first foldable line, and wherein the common side and the first pair of perforated lines are perforated with different sizes of perforations.
