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 wall panel 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 wall 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.
A carton blank formed from a continuous sheet of material and capable of being easily folded into a self-supporting carton structure. A unique cover locking arrangement is provided whereby both lids forming the cover are independently locked against accidental opening without the aid of external fasteners and further provide superior protection for the contents of the carton against dust and moisture. The absence of external fasteners also make the carton more economical to manufacture and aesthetically pleasing to look at. The carton is also equipped with improved hand holes to facilitate balancing and carrying of the box when loaded.
A container (10) formed from a one-piece blank (12) including a bottom panel (14), first and second opposed side walls (16), (18), and first and second end walls (20), (22). A top lid panel (24) connects to the first side wall and a bottom lid panel (26) connects to the second side wall. A locking tab (46) is formed in the first side wall and includes a thumb notch (48) located within the tab. The top lid panel includes a pair of cover latches (28) located on the outer corners thereof. The bottom lid panel includes a pair of alignment tabs (40) located on the outer corners thereof. Each end wall includes a hand hole lock (60), a lock slot (64), and a recess (66) located along the end wall exterior edge. The lock slot is located between the recess and the hand hole lock. Each end wall further includes first and second reinforcing panel sub-assemblies (56), (58), each having an inner panel (70), (100), a middle panel (72), (102), and an outer panel (74), (104). Each inner panel includes a pair of recesses (82) and an intermediate tab (84) all located along an inner panel exterior edge. Each middle panel includes a locking slot (86) near the middle panel exterior edge. The outer panel (74) of the first sub-assembly includes a recess (78) along an outer panel exterior edge and a hand hole (80). As assembled, the locking tabs are disposed within the lock slots with the intermediate tab of the inner panel at least partially inserted into the locking tab thumb notch. The cover latches are inserted into the locking slots of the end walls. The alignment tabs are positioned in the aligned recesses of the outer panel and the end wall.
