Abstract: A reinforced cardboard box for storage and shipping of elongated items and rolled documents is described. The box is formed from a single piece of cardboard and may be rapidly assembled without the use of tools. The box comprises an elongated rectangular bottom panel, first and second joined side panels, and first and second abutting top panels foldably joined to the side panels and constructed to form a center top closure for the box. The second top panel includes a series of tab openings. The center closure permits the finished box to be sealed by an automated tape machine. A reinforcing rib panel, having a series of bendable tab elements extending from an elongated edge, is foldably joined to the second top panel. The bottom panel has a pair of abutting end panels foldably joined to either end. The second side panel has a pair of outer side end panels foldably joined to either end and a pair of inner side end panels foldably joined to the outer side end panels.

Abstract: A reinforced paperboard box for storage and shipping of elongated items is described. The box is formed from a single piece of paperboard and may be rapidly assembled without the use of tools. The box comprises an elongated rectangular bottom panel, first and second joined side panels, a top panel, a front reinforcing panel and dividing partition all foldably joined at elongated edges and constructed to form a multi-level elongated box. The first side panel has a pair of abutting end panels foldably joined to either end, with a tab receiving panel and a locking panel foldably joined to either side of the end panel. The second side panel has a pair of end panels foldably joined to either end, that are locked in place by the locking panels and tab receiving panels of the first side panel.
