ABSTRACT:
This invention relates to a stackable file storage carton characterized by an open-front box fitted with an integrally formed access opening cover hingedly attached to the bottom of the box along the front edge of the latter for movement from a closed position into an open one forming an extension of said box bottom. The access opening cover is comprised of a panel sized and shaped to cover the access opening. This panel is bordered along its free edges by upstanding fence-forming flanges cooperating therewith and with one another to define a tray which in open position is adapted to receive and support a file slid forwardly from within the box. The front flange is formed to provide a pocket extending lengthwise thereof which is open at both ends to receive and hold tabs depending from the front edges of the flanges bordering the sides of the cover panel. When thus interconnected and with one or more tongues depending from a section of the front flange seated in slits in the cover panel alongside thereof, the interlocked connection between the flanges is complete and effective to maintain them in upstanding position relative to one another and to the cover panel.
