ABSTRACT:
A collapsible multiple shelf file is constructed of a sheet of cardboard or the like, cut and scored to define a plurality of panels foldable into an open front box-like structure having double side walls with inner sidewalls having slots for receiving a plurality of shelf panels. The side panels are double with inner panels that overlap and extend to the inside of the outer panels and further overlap flaps which extend downward from the top panel and similar flaps which extend upward from the bottom panel. The outer side panels are formed with rectangular cuts for defining a loop for receiving and holding stacked material such as envelopes. The top panel includes cut circles which can be punched out for receiving tubular members for holding pencils and the like. The shelf sheets or panels are provided with a stop member which may be folded upward to stop short forms or sheets of paper.
