Expanding file with pocket divider

Abstract

A portable, expandable file section case is equipped with file section dividers, at least some of which are provided with pockets. The file section dividers of the invention are formed of a laterally expansive partition with a pocket attached thereto. The pocket may be formed either from the same sheet of material as the file section divider partition, or from a second sheet of material. For example, the pocket may be formed by an extension of the same sheet of material that projects from the lower edge of the partition and is folded back up into contact with the divider partition. The opposing pocket panel side edges may be secured to the file section divider partition by sonic welding or some other means. Alternatively, the pocket may be formed from a second sheet of material having a generally rectilinear configuration and formed in the manner of a patch on the divider partition. The pocket is secured along its bottom edge and its opposing side edges to the divider partition. Alternatively, the second sheet of material forming the pocket may be folded in half along a pocket bottom fold that divides the second sheet into a backing panel and an apron panel. The apron panel is folded up against the backing panel and may be secured thereto or to the file section divider partition behind the backing panel. In either case the upper margin of the backing panel is suspended from the divider partition near the upper edge of the divider partition.
