Embodiment Construction

[0020]A first embodiment of a triple-thickness sidewall box of the invention is shown in FIGS. 1-6. This embodiment is formed from the unitary blank of material 10 shown in FIG. 1. Blank 10 may be constructed of any material that will form a stiff panel surface. Preferably, blank 10 is made from a single thickness corrugated material, which is a material with two layers of linerboard separated by a single layer of fluted material. Such a corrugated material can be constructed from different substances as is known in the art. The material can have several different constructions. Corrugated material is typically constructed from fiber materials or plastic materials. Preferably the corrugations run parallel to the direction of arrow A, FIG. 1. Blank 10 is formed through die cutting and creasing of corrugated material as is known in the art.

No. 61 / 185,734 filed on Jun. 10, 2009, the entire contents of which are expressly incorporated by reference herein.FIELD OF THE INVENTION[0002]The invention relates to boxes made from corrugated materials.BACKGROUND OF THE INVENTION[0003]File storage boxes typically have single or double thickness sidewalls. When these boxes are full of files, they are heavy. When full boxes are stored one on top of another, the cumulative weight can crush boxes toward the bottom of the pile. Accordingly, there is a need for file storage boxes that can support greater vertical loads, but are assembled in essentially the same manner as other file storage boxes.SUMMARY OF THE INVENTION[0004]This invention features boxes for file storage and the like. The inventive box is made from a unitary blank of material. The box, when assembled, has four interconnected sidewalls ...
