Abstract: A bulk container is formed from a blank of corrugated sheet material having wall fold lines demarcating end wall panels and side wall panels, and flap fold lines demarcating top and bottom closure flaps. A T-shaped slot in the blank separates adjacent closure flaps from one another. A first portion of each slot extends inwardly from the free outer edges of the closure flaps and terminates at a second portion which extends substantially perpendicular to the first portion. The first portion of each slot is substantially aligned with a corresponding wall fold line. The second portion of each slot extends substantially colinearly with a flap fold line. The slots reduce binding and bunching of the thick multilayer reinforced walls found in conventional bulk container constructions, and at the same time avoid formation of through-holes at the corners of the container.

The cover is formed with a deformable band which is integral with the material of the cover and constitutes the handle of the container. The band is obtained by providing the cover with two cuts which extend side by side between two opposite upper edges of the cover. In the middle part of the cover, the cuts deviate to form two rectangular tabs. The cuts also extend downwardly past the upper edges a short distance to enable the band to arch upwardly when upwardly pulling it. The cuts are oriented in such a way that the band is widest at the cover edges, and narrowest at the ends of the cut extensions and at the middle part of the cover.

Abstract: A quick-assembly corrugated box has an automatic bottom panel which extends from a side panel, and has two converging reverse-scored fold lines which extend outwardly from the side panel. End flaps are folded up from the automatic bottom panel and are adhesively connected to the end panels to form double ply side walls. One of the end flaps has a diagonal fold line, with portions of the flap above the diagonal fold line only being adhered to the end panel. The angles of the reverse scored fold lines are selected to allow the automatic bottom panel to be deployed from a folded position alongside the side and end panels to an assembled position perpendicular to the side and end panels, simply by displacing one side panel with respect to the other. Substantially increased stacking strength is provided by inserting right-angle corner pieces in reinforcement-receiving pockets defined between the edges of the end flaps and the end panels.

Abstract: A thin, pliable, self-adhesive corner reinforcement for cardboard boxes. Two adjacent side panels are pivotally connected by a narrow vertical crease which affords a bending capability without fracture. Each of the side panels is pivotally connected to a base flap by a narrow horizontal crease extending the width of each side panel to allow a non-fracturing bending capability. The outer and inner edges of the base flaps are trimmed directionally toward each other to form a triangular shape while the apex of each triangle is bevelled and the corner formed at the right angle in the outer upper quadrant of each side panel is also bevelled. An adhesive covers the reinforcement in its entirety on one side. A peel-off strip covers the adhesive to prevent premature adhesion and has cut lines at the vertical and horizontal creases of the reinforcement to facilitate singular removal and ease of application.

Abstract: A box has front and back walls and a bottom wall extended between the lower margins of those walls. It also has side walls that are attached to the front and back walls and close the sides of the box. Each side wall contains two panels which are joined together at a manufacturer's joint midway between the front and back walls to create a column within the side wall. The column extends all the way to the bottom wall and enhances the strength of the side wall. In one embodiment the columns in the side walls support a beam that extends through the box and items may be suspended from the beam. In another embodiment, the bottom wall folds, as do the side walls at their columns, so that the box may be supplied in a knocked-down condition.
