Abstract
An origami envelope and a method of constructing the origami envelope are enclosed. The origami envelope is quadrilateral in shape. The origami envelope comprises a top layer having a front surface and a back surface opposite to the front surface, and a bottom layer having an exterior side and an interior side opposite to the exterior side. The top layer extends to the exterior side of the bottom layer over a portion of the top envelope side to form a closure flap at the exterior side of the bottom layer.
Claims15
A method of forming an origami envelope comprising:
- providing a sheet of material having a top right corner, a top left corner, a bottom right corner, and a bottom left corner, a top edge extending between the top right corner and the top left corner, a bottom edge opposite of the top edge, extending between the bottom right corner and the bottom left corner, and a first and second side extending between the top and bottom edges, the first side extending between the top left corner and the bottom left corner, and the second side opposite of the first side, extending between the top right corner and the bottom right corner;
- orienting the sheet of material such that the top and bottom edges extend width wise, and the first and second sides extend length wise;
- folding the sheet of material to create at least five fold lines, the at least five fold lines comprises:
- a first fold line extending diagonally between a first side point positioned at one of the first and second sides and a first edge point positioned at one of the top and bottom edges;
- a second fold line extending diagonally between a second side point positioned adjacent the first side point and a second edge point positioned at the edge opposite to the edge having the first edge point;
- a third fold line extending diagonally between a first endpoint positioned adjacent to the second edge point and a third side point positioned at the side opposite to the first and second side points;
- a fourth fold line extending diagonally between a second endpoint and a third endpoint, wherein an orthogonal projection of the second endpoint onto the first fold line is located between the first edge point and the first side point and the orthogonal projection of the third endpoint onto third fold line is located between the first endpoint and the third side point;
- and
- a fifth fold line extending diagonally between a fifth edge point positioned adjacent to the first edge point and a sixth side point positioned at the same side as one of the top or bottom corners.
