Abstract
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 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° 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° 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
253 words
A box comprising: a bottom wall having a first and second pair of opposed, parallel edges, a side wall connected to each of the first pair of opposed edges of said bottom wall, an end wall connected to each of the second pair of opposed edges of said bottom wall, each of said end walls including a pair of abutting end panels, each of said abutting end panels being connected to an edge of one said side walls, and a third end panel connected to one of said second pair of opposed edges of said bottom wall overlapping said pair of abutting end panels, a top flap for forming a top wall for said box connected to an edge of each of said side walls, the third end panel of each end wall including an opening, each of said top flaps including a bendable tab extension extending from opposite ends thereof received within said opening in each of said third panels of each end wall, and said end panels having means therebetween for locking said end panels together, said locking means including an upright tab on the top edge of each of said pair of abutting end panels, a pair of spaced openings for receiving said upright tabs cut in said third end panel along a foldline spaced intermediate spaced transverse edges thereof, and each of said top flaps including an opening cut therein adjacent each end thereof for also receiving an upright tab of one of said pair of abutting end panels.
Claim 2
Dependent Claim
253 words
A box comprising: a bottom wall having a first and second pair of opposed, parallel edges, a side wall connected to each of the first pair of opposed edges of said bottom wall, an end wall connected to each of the second pair of opposed edges of said bottom wall, each of said end walls including a pair of abutting end panels, each of said abutting end panels being connected to an edge of one said side walls, and a third end panel connected to one of said second pair of opposed edges of said bottom wall overlapping said pair of abutting end panels, a top flap for forming a top wall for said box connected to an edge of each of said side walls, the third end panel of each end wall including an opening, each of said top flaps including a bendable tab extension extending from opposite ends thereof received within said opening in each of said third panels of each end wall, and said end panels having means therebetween for locking said end panels together, said locking means including an upright tab on the top edge of each of said pair of abutting end panels, a pair of spaced openings for receiving said upright tabs cut in said third end panel along a foldline spaced intermediate spaced transverse edges thereof, and each of said top flaps including an opening cut therein adjacent each end thereof for also receiving an upright tab of one of said pair of abutting end panels.
Claim 3
Dependent Claim
25 words
The box of claim 1 wherein one of said top flaps is wider than the other so as to overlap to form said top wall.
Claim 4
Dependent Claim
12 words
A one-piece, planar, paperboard blank for forming the box of claim 1.
Claim 5
Dependent Claim
12 words
A one-piece, planar, paperboard blank for forming the box of claim 2.
Claim 6
Dependent Claim
224 words
A blank for forming a box comprising a central, substantially rectangular panel having opposed longitudinal and transverse edges, a substantially rectangular side panel foldably connected to each of the longitudinal edges of said central panel, each of said side panels having opposed longitudinal and transverse edges, a substantially rectangular top and bottom panel foldably connected to opposed transverse edges of each of said side panels, a substantially rectangular panel connected to each of the transverse edges of said central rectangular panel, a substantially rectangular panel approximately half the width of said central panel foldably connected to a longitudinal edge of each of said side panels, said half-width panels having opposed longitudinal and transverse edges, an elongated tab foldably connected to each transverse edge of each of said half-width panels, said rectangular panel foldably connected to each of the transverse edges of said central panel having a substantially centrally located opening cut therein, the rectangular panel connected to each of the transverse edges of said central panel including a foldline spaced intermediate spaced transverse edges thereof, and a pair of cut lines extending upwardly from said foldline for forming a pair of spaced openings along said foldline, and each of said substantially rectangular panels foldably connected to a longitudinal edge of each of said side panels including an opening cut therein adjacent each end thereof.
Claim 7
Dependent Claim
224 words
A blank for forming a box comprising a central, substantially rectangular panel having opposed longitudinal and transverse edges, a substantially rectangular side panel foldably connected to each of the longitudinal edges of said central panel, each of said side panels having opposed longitudinal and transverse edges, a substantially rectangular top and bottom panel foldably connected to opposed transverse edges of each of said side panels, a substantially rectangular panel connected to each of the transverse edges of said central rectangular panel, a substantially rectangular panel approximately half the width of said central panel foldably connected to a longitudinal edge of each of said side panels, said half-width panels having opposed longitudinal and transverse edges, an elongated tab foldably connected to each transverse edge of each of said half-width panels, said rectangular panel foldably connected to each of the transverse edges of said central panel having a substantially centrally located opening cut therein, the rectangular panel connected to each of the transverse edges of said central panel including a foldline spaced intermediate spaced transverse edges thereof, and a pair of cut lines extending upwardly from said foldline for forming a pair of spaced openings along said foldline, and each of said substantially rectangular panels foldably connected to a longitudinal edge of each of said side panels including an opening cut therein adjacent each end thereof.
