Abstract
A box for storing files is formed from a single blank of paperboard. The blank consists of a centrally located bottom wall panel having side wall panels foldably connected thereto. Each of the centrally located bottom walls panels and side wall panels have an end wall panel extending from a transverse edge thereof so that when the side wall panels are folded 90.degree. relative to the bottom wall panel, the end wall panels on the transverse edges of the side walls and bottom walls can be overlapped and locked together. Connected to the outer longitudinal edges of each of the side wall panels is a top wall panel substantially half the width of the centrally located bottom panel. The top wall panels are adapted to be folded 90.degree. relative to the side walls to form a cover for the box. Longitudinally extending tabs extend from the transverse edges of each of the top wall panels and can be inserted within an opening in the end walls to lock the top wall panels in place on the box.
