Abstract: A box with a wheel assembly platform has a tow strap with a folded position stowed in a recess in the platform and an unfolded position accessible outside the box. In one embodiment, the strap is incorporated in a pre-assembled handle pack positioned in the recess. The strap may be retracted by a torsion spring, and may be coiled in the pack by use of a rotating fork. In one embodiment axles projecting from rollers are supported in recesses formed in the platform, and in another embodiment the axles are supported in notches in the bottom end of cylinders mounted in cutouts in the platform. In a further embodiment a box has hand holes in opposite walls with a spacer panel providing finger access behind the holes. The platform may have hinged panels. A thermoformed skin may be applied to the platform or constitute the platform.

Abstract: A carton has hand holes in opposite walls and a spacer panel inserted between stacked articles in the carton. The spacer panel has cut outs in its opposite ends positioned behind the hand holes to provide space for inserting the fingers. The hand holes and spacer panel facilitate lifting, carrying and manipulating the carton. The spacer panel has width and length dimensions to fit within the interior width and length dimensions of the carton and reinforces the carton to reduce damage when the carton is dropped.

Abstract: An end closure design for a paperboard container having four or more end panels that form the end closure hingedly joined respectively to four side panels connected to each other by parallel, spaced apart fold lines. Each of the hinged end panels has a straight free edge parallel the hinged edge and each free edge has two spaced apart notches of the same shape and size cut therein, each positioned the same distance from the parallel, spaced apart fold lines such that when the panels are folded over, a notch from each end panel interlocks with a notch from an adjacent end panel. An opposing two of the hinged end panels also include two diagonal score lines, each extending from an interior edge of the notches to the interior corner formed by the fold lines between the end closure panel and its respective side panel. To form the end closure, the end closure panels without the diagonal score lines are folded inwardly, then the end closure panels with the diagonal score lines are folded inwardly.

Abstract: A corrugated paperboard bulk box has opposed pairs of parallel side walls, and in a preferred embodiment, has interposed diagonal corner panels to form an octagonal box. The bottom of the box is closed by opposed pairs of interlocking major and minor bottom flaps, wherein one pair of flaps have notches in their free edges and the other pair of flaps have T-shaped locking tabs in their free edges. The notches form a central opening in the bottom when the flaps are folded closed, and the locking tabs are pushed through the opening to lock the flaps closed. Aligning tabs project outwardly from opposite side edges of one pair of opposed bottom flaps, and complemental slots are formed at the folding connection of another pair of bottom flaps, so that when the flaps are folded inwardly toward one another, the tabs extend into the slots to square the box and hold it square.
