Improved spiral bound notebook and folder construction is disclosed which is formed from an integral blank of flexible sheet material. The folder includes a pair of hingedly interconnected opposed cover panels, a pocket-forming panel hingedly connected along an edge of one of the cover panels and a closure flap hingedly extending from the outer edge of the other cover panel. The pocket forming panel includes one edge portion which is adapted to be folded in superposed relation along one side of the hinge line which interconnects the two cover panels. The folder also includes another flap portion which overlays the other side of the hinge line. The folder is punched to provide wire holes on opposite sides of said hinge line through the cover panels, superposed edge portion of the pocket forming panel and the other flap portion of the folder. A continuous wire is helically wound through the wire holes in the folder and through corresponding wire holes or perforations disposed along the inner edge of a pad of loose leaf notebook paper.
Spiral bound notebook comprising a cover formed of a blank of unitary sheet material having a front cover panel and a back cover panel, said cover panels being interconnected at their inner edges by a hinge line, at least one other panel pivotable about a fold line normal to said hinge line into superposed relation over a portion of at least one of said cover panels which is adjacent said hinge, means for securing the edge of said other panel opposite its fold line, a series of closely spaced perforations being formed in alignment along each side of said hinge, a binder wire disposed in helical configuration in said perforations, at least some of said perforations extending through the superposed portion of said one cover panel and said other panel to form a storage pocket in said notebook, the helical wire defining the inner portion of said pocket and adapted to bind a perforated pad of paper within said notebook.
