  • Patent number: 8998073
    Abstract: A stackable open topped box and a blank from which it is folded are provided in which a fluted sheet material is cut and sulcated to form a box The flutes extend parallel to the side walls of the box and up the height of the end walls. Each side wall has an indent whereof the ends terminate in a diagonal fold inclined upwardly and towards the adjacent end of the box at an angle of 45°. The fluted sheet material originally adjacent the edge of the indent is folded inwards and downwards as a composite flap such that the flutes of the fluted material are generally vertical and the material extends to substantially the bottom of the box. A strip that is approximately beneath the diagonal fold is flush with the inside of the side wall of the box.

    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.

    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.

  • Patent number: 6158652
    Abstract: A container for holding produce having a floor, four sidewalls and a cover. Two of the four sidewalls are multi-layered with a core including a plurality of interlocking panels. The interlocked panels are lockingly connected in coplanar pairs through a set of complementary locking contours. Pairs of interlocked panels overlap in a back-to-back relationship to form a "dual-lock" arrangement. The coplanar, dual-lock arrangement allows the sidewalls and floor to be tightly interlocked thereby enabling the container to resist higher loads without buckling. The cover panels protect the enclosed produce while letting in air for ventilation through a plurality of ventilation holes.

  • Patent number: 6098873
    Abstract: A container is made in a collapsed configuration with bellows fold corners for self-erection and has spaced-panel end walls encompassing hollow columns for vertical reinforcement. An outer end wall panel is joined to the container bottom, leading to a ledge panel that is horizontal when the container is erected, and an inner end wall panel folds over and down to lock via tabs into openings in the bottom. The hollow columns reside under the ledge panel and are provided by column-forming panels folded inwardly and glued to the inner end wall panels. Score or fold lines define the corners of the hollow column and are placed to bear against inner sides of the front and back walls, which holds the hollow columns open when the container is erected. The column-forming panels have protruding tabs backed by corresponding tabs on a ledge panel between inner and outer panels of the end walls. These tabs form a two thickness registration tab that engages a corresponding opening in the container bottom for stacking.

  • Patent number: 5950915
    Abstract: A stackable container comprising an erected H divider and a body wrap, both of corrugated cardboard material. The H divider has a laminated partition, opposite ends of which have a pair of end wall panels, each having an integral corner post flap. The flutes of the corrugated media of the erected H divider are all oriented vertically. The body wrap comprises a bottom panel that is flanked at opposite ends by an erected pair of end walls, each of which has integral corner post flanges. Opposite sides of the bottom panel are flanked by a pair of window flanges, each having a compressed tab area at opposite ends. Each adjacent pair of end wall areas of the erected H divider have a combined area which is congruent to the superposed area of an end wall of the body wrap. The flutes of the media of the body wrap end walls and corner post flanges extend vertically and parallel to the flutes of the H divider end wall panels.

  • Patent number: 5913474
    Abstract: A foldable tote box is formed by a one-pierce die-cut and scored board of corrugated material, especially corrugated plastic materials. The board includes a rectangular bottom panel having a length and a width defined by pairs of side and end edges. Each of a pair of sidewall panels has a folding edge integrally connected to the side edge of the bottom panel along a first scored folding line, a top edge and a pair of end edges that define a height of the box. Each pair of two filler beam panels are integrally connected to the end edges of one of the sidewall panels along second scored folding lines. Each filler beam panel is folded to form a hollow support beam. A pair of end wall panels are integrally connected to the end edges of the bottom panel along third scored folding lines. Each end wall panel includes an end wall section and a flap section divided by double scoring lines, thereby defining a support surface between the double scoring lines.
