Abstract
A cardboard blank has a plurality of fold lines dividing the blank into section for folding into a loose leaf folder or a box file. The fold lines define two cover sections between which there is a spine portion having multiple spine fold lines defining a binding zone which can be formed as a double thickness ridge to which papers can be attached. The fold lines additionally define various flaps which can be folded flat onto the cover portions to form a loose leaf file or which can extend to form a box shape with the cover portions and spine portion.
Claims14
A loose leaf folder comprising a first cover portion, a second cover portion and a spine portion therebetween, characterized in that:
- (a) said first cover portion comprises a first flap portion at an edge opposite said spine portion and demarcated by a first fold line, second and third flap portions on each opposite edge demarcated by second and third fold lines;
- (b) said second cover portion comprises fourth and fifth flap portions on each opposite edge and are demarcated by fourth and fifth fold lines;
- and
- (c) said spine portion comprises a binding portion demarcated by a plurality of spine fold lines, whereby said binding portion is foldable along said spine fold lines to form a double thickness ridge to which documents can be secured;
- wherein said first cover portion is foldable to lie in a plane parallel to said second cover portion and said first, second, third, fourth and fifth flaps are foldable flat against said first and second cover portions.
A box file comprises a first cover portion, a second cover portion and a spine portion therebetween, characterized in that:
- (a) said first cover portion comprises a first flap portion at an edge opposite said spine portion and demarcated by a first fold line, second and third flap portions on each opposite edge demarcated by second and third fold lines;
- (b) said second cover portions comprises first and second flap portions on each opposite edge and are demarcated by fourth and fifth fold lines;
- and
- (c) said spine portion comprises a binding portion demarcated by a plurality of spine fold lines, whereby said binding portion is foldable along said spine fold lines to form a double thickness ridge to which documents can be secured;
- wherein said first cover portion is foldable to lie in a plane parallel to said second cover portion and said first, second, third, fourth and fifth flaps are foldable along the respective said fold lines such that said flaps are perpendicular to said first and second cover portions.
A document file blank adapted to be folded selectively into a box file or into a loose leaf file folder, said document file blank having a first cover portion, a second cover portion and a spine portion in continuity, characterized in that:
- (a) said first cover portion comprises a first flap portion at an edge opposite said spine portion, demarcated by a first fold line, and second and third flap portions on each opposite edge, demarcated by second and third fold lines;
- (b) said second cover portion comprises fourth and fifth flap portions on each opposite edge, demarcated by fourth and fifth fold lines;
- and
- (c) said spine portion comprises a binding portion demarcated by a plurality of spine fold lines, said binding portion being foldable along said spine fold lines to form a double thickness ridge adapted for securement of documents thereto;
- wherein said first cover portion is foldable to lie in a plane parallel to the second cover portion and the first, second, third, fourth and fifth flap portions are foldable along the respective said fold lines to selectively form a box file or are foldable flat against said first and second cover portions to form a loose leaf file folder.
