  • Patent number: 7677434
    Abstract: A stackable container has a bottom panel, upstanding sidewalls, upstanding end walls, and an open top. According to one aspect of the invention, narrow reinforcing flaps are attached to the upper edge of at least one of the side and end walls, defining a stacking ledge and reinforcing the walls against outward bulge. The reinforcing flaps extend over only a small portion of the height of the side or end wall, and corner post flaps extend from opposite ends of the reinforcing flaps, extending diagonally across interior corners of the container. According to another aspect, the side and/or end walls lean inwardly, defining a narrower footprint at the top of the container than at the bottom. In a specific embodiment one of the walls leans in more than the other. According to a further aspect, an indexing and aligning tab extends upwardly from an upper edge of the container, and a complementary notch is formed in a lower edge for receiving the tab when the containers are stacked.

These tabs form a two thickness registration tab that engages a corresponding opening in the container bottom for stacking.

  • Patent number: 6508395
    Abstract: A stackable shipping container for shipping articles such as produce, which is open-topped. The shipping container is preferably provided with stacking indexing tabs configured to be received by corresponding slots in the bottom of a like container stacked atop a first such container. Inwardly inclined diagonal corner gussets are provided for providing support of the bottom of a container stacked above one such container, while increasing available container volume.

  • Publication number: 20030010816
    Abstract: A container for transporting meat, produce, and other goods contains a bottom wall, side walls, and end walls. The end walls include hinged platform structures movable between a closed position and an open position. The closed position enables stable stacking of multiple containers and the open position allows easy access to the interior of the container for loading and unloading. The hinged platforms further add stability to the container walls when in the closed position.

  • Publication number: 20020179481
    Abstract: A container has a bottom panel, side walls, and end walls, with the bottom panel having recesses for accepting stacking tabs The side walls are provided with stacking tabs which are tapered inwardly so as to align with the recesses in the bottom panel of a second container. The inwardly tapered tabs allow for easy stacking without the tabs being deformed when containers are stacked atop one another. To improve strength, the side and end walls are disposed approximately at right angles to the bottom panel. Multiple plies of material are used along the container walls to increase container strength.

  • Patent number: 6481619
    Abstract: A produce container comprises a bottom wall, a pair of opposing side walls, a front wall, and a back wall. The front and back walls are reinforced along their tops by partial rollovers, each of which comprises two flanges—a center flange and a major flange—hingedly attached to the wall being reinforced. Each rollover is formed by first folding the center flange slightly away from the major flange and then folding the major flange downward toward the corresponding wall. Folding the major flange captures the center flange and at the same time forms doubled, indexed stacking tabs whose tops are formed along the axis about which the major flap is folded. The corners where the side walls and front and back walls join are reinforced by corner structures, with the corner structures extending along a portion of each of the joining walls so that the corners are reinforced along each wall with at least two layers of vertically-corrugated paperboard.

  • Patent number: 6460758
    Abstract: A corrugated board tray has stacking lugs extending from double thickness side walls. The stacking lug is formed from an integral upward extension of only the outer one of the side wall panels. The lug is folded inwardly and secured to the inside of the side wall. Corresponding slots are formed at the junction of the side wall and the base to receive the stacking lugs of a lower tray. Half-size trays may include stacking lugs and slots formed in the end walls.

  • Patent number: 6443358
    Abstract: A stackable container formed from a single-piece blank pre-cut and pre-scored with an improved design directed at providing material cost savings while achieving stacking stability and related benefits. The container includes a base with two sets of opposing walls. Each wall of the first set incorporates a first panel and a second panel. The first panel is foldably attached at a lower edge to the base and is hinged at an upper edge to the second panel, wherein the upper edge also defines a shoulder. Each wall of the first set further incorporates at least one stacking tab that extends beyond the shoulder. The stacking tabs are two-ply and have a tab base and a sequencing panel. The tab base extend from the first panel and is foldably attached to the sequencing panel, wherein the tab base and the sequencing panel are formed from material cut from the second panel, thereby providing the benefits of two-ply stacking tabs and two-ply walls without expanding size requirements of the blank.

  • Patent number: 6375068
    Abstract: The present invention provides a stackable open-top container for use in shipping, storing and retail display of produce and other articles. The produce container of the present invention contains a bottom wall, two side walls, and two end walls. The concave ledges of the side walls contain curved scores. Each side wall contains two panels, each of which contains a mirrored curved score and two minor flaps. The curved scores cause the side walls to go into tension and create stacking shoulders for other containers. The minor flaps of the side walls surround the end walls to increase structural rigidity.
