Abstract: A container made from corrugated paperboard has a bottom wall, opposite side and end walls, and a self locking arrangement on the end walls holding the container in erected condition. The self locking arrangement includes first and second end panels on opposite ends of the side walls, and a third end panel on opposite ends of the bottom wall. The end panels form the end walls of the container. The first and second end panels have at least one notch formed in an upper edge, and a roll over flap is foldably joined by at least one web to an upper edge of each of the third end panels and is folded inwardly and downwardly over the upper edges of the first and second end panels into a locked position to hold the end panels and thus the container in erected condition. In the locked position, the web is engaged in the notch.

Abstract: A corrugated paperboard container (10) has a bottom (11), opposite side walls (12, 13) and opposite end walls (14, 15). The end walls include an end panel (18) that is foldably connected to the bottom, and end flap panels (16, 17) that are foldably connected to the side walls. A roll-over flap (23) is connected to the end wall by a web (24), and a notch (20) is in the top edge of the end flap panels. The end wall panel and end flap panels are folded into overlying relationship, and the roll-over flap is folded over an upper edge of the end wall panel, with the web lying in the notch. A projection or hook (41) extends into one side of the notch to engage an edge of the web to retain the web in the notch. A blank for making the container is also disclosed.

Abstract: An octagonal bulk bin has sidewalls, end walls and diagonal corner panels interposed between adjacent sidewalls and end walls. Major bottom flaps are foldably joined to a bottom edge of the sidewalls, minor bottom flaps are foldably joined to a bottom edge of the end walls, and diagonal bottom flaps are foldably joined to a bottom edge of the diagonal corner panels. A cut separates each major bottom flap from an adjacent diagonal bottom flap, and a web panel connects adjacent side edges of the minor bottom flaps and diagonal bottom flaps. According to one aspect of the invention, each diagonal bottom flap, web panel, and portion of an adjacent major bottom flap are crushed. According to another aspect of the invention, differently shaped notches in a free edge of the minor flaps form locking tabs that are engaged in slots near a free edge of the major flaps.

Abstract: A bin (10, 40, 50, 70, 80) has an auto-closing bottom and can be manufactured and shipped and stored in a flattened configuration and moved to an open expanded configuration at a point of use. The bin has opposed sidewalls (11, 12) and opposed end walls (13, 14 and 15, 16) and major bottom flaps (18, 19) on the sidewalls and minor bottom flaps (20, 21 and 22, 23) on the end walls. The flaps automatically move to their closed position when the bin is moved from its flattened configuration to its expanded configuration. A connecting web (25-28, 43) is foldably connected between each major bottom flap and an adjacent first side edge of an adjacent minor bottom flap, and adjacent side edges of the minor bottom flaps are foldably interconnected (29, 30 or 44), so that when the sidewalls and end walls are moved from their flattened configuration to their open expanded configuration, the major and minor bottom flaps automatically fold inwardly toward one another to close the bottom of the bin.

Abstract: A container (21) for storing and shipping produce is reinforced with at least one cross beam (20) extending across the bottom wall (26) of the container to form a bridge under loose product placed in the container to support at least a portion of the weight of the product and prevent sagging of the container bottom. The cross beam is positioned and held in place by engaging the ends of the cross beam in recesses (71) formed by crushed areas (82) on an inner surface of opposing side walls, or cut-outs (93) in the side walls, and/or by flaps (42, 43) folded upwardly from the container bottom wall and to which the cross beam is attached.

Abstract: A container made from corrugated paperboard has more than four sides and is constructed to resist distortion when force is applied to the ends or sides of the container, and also to resist crushing when containers are stacked on top of one another. In one embodiment, the container has six sides, with two side walls, two end walls, and two diagonally opposed diagonal corner panels and two diagonally opposed square corners. In another embodiment, the container has seven sides, with two side walls, two end walls, and three diagonal corner panels and one square corner. In a further embodiment, the container has eight sides, with two side walls, two end walls, and four diagonally opposed diagonal corner panels. In this embodiment, the diagonal corner panels are oriented so that they subtend an angle of from about 35° to about 40°, and preferably 38°, with respect to the longitudinal axis of the container.

Abstract: A container made from corrugated paperboard has at least one mitered corner, with an extended edge portion of one of the container walls extending beyond the mitered corner. A bag cuff grab is formed on the extended edge portion to engage and at least temporarily hold in position a bag placed in the container while product is placed in the bag and container. In one embodiment, the container has six sides, with two side walls, two end walls, and two mitered corners. In another embodiment, the container has seven sides, with two side walls, two end walls, and three mitered corners. In a third embodiment, the container has eight sides, with two side walls, two end walls, and four mitered corners. A bag cuff grab can be formed on an extended edge portion at only one or all of the mitered corners, and can be limited to two bag cuff grabs on extended edge portions at diagonally opposite mitered corners. In a preferred embodiment, the bag cuff grab is a notch formed in the extended edge portion.
