  • Patent number: 6076690
    Abstract: A container includes a palletized base for which at least four side walls can be releasably secured without the use of separate fasteners. A cover can also be releasably secured to the four side walls without the use of separate fasteners. The releasable securing of the container components is accomplished by a series of dowel holes defined in the base and cover. Corresponding dowel pins fit into the dowel holes for secure attachment that permits easy disassembly and reassembly.

  • Patent number: 5813555
    Abstract: The present invention provides a cleated crate for packaging, storing, and shipping heavy articles. The cleated crate includes a base frame for supporting an article to be packed, a pair of wing-end frames that define ends and side portions of the cleated crate. The wing-end frames comprise a pair of hinge corners each having a pair of spaced apart cleats attached to a fibreboard plate with a score along an axis. The fibreboard plate folds on the score to define a corner post of the cleated crate. A portion of the side of the cleated crate is defined by a side member and a support member attached to one of the pairs of cleats on the fibreboard plate. Elongate members connect two hinge corners together to define a wing-end frame. A pair of wing-end frames are positioned and attached to opposite ends of a base frame or pallet. Intermediate connectors rigidly connect on opposite sides to aligned hinge corners at the opposite ends of the cleated container.

  • Patent number: 5669507
    Abstract: The specification discloses a collapsible pallet box or container composed of a pallet platform and four upright panels connected together at the corner edges by flexible material to form a polygon expandable to a rectangle or collapsible to a flattened parallelogram. The bottom of the polygon panels are removably attached to the pallet. The tops of the panels have a stabilizing grid with interconnected compression elements between the panels to stabilize the panel tops in the expanded rectangular configuration, and interconnectable, releasable hook and loop fasteners on the grid and on the polygon upper end, at the corners of the grid and recessed into the corners of the polygon, to keep the grid secured to the polygon and thereby keep the polygon locked to the pallet.

  • Patent number: 5386919
    Abstract: A fully collapsible box with four sidewalls comprising vertical slats, horizontal cleats and interconnected wires at the ends of the cleats at the corners of the box, wherein the ends of the cleats have reverse miters so that the box may be hingedly collapsed along these corners when not in use. Hinged collapsing of this box does not require disconnection of the wires and does not adversely affect the tightness of the wire interconnections between adjacently located cleats. Because the reverse miters allow the box to be hingedly collapsed while the sidewalls remain interconnected, this invention assures a sturdy box over a period of use, while eliminating the need to connect and disconnect the cleats at the corners of the box during assembly and disassembly, respectively. In one embodiment the wire internconnection comprises a single loop extending completely around the box and secured to the cleats.

  • Patent number: 4664282
    Abstract: A structure for holding plants, flowers or other objects utilizes a plurality of generally rectangular bar members having a hole at each end, the generally rectangular bar members being stacked in alternate directions in a rectilinear array, the holes proximate the ends of the bars aligned with like holes in the ends of other of said bars, with a set of assembly rods each engaging the aligned holes to define a rectilinear structure, hinged at each corner. A tray having a rectilinear shape, such as, a rectangle or parallelogram (diamond) is adapted to be inserted between a selected layer of assembled bars and engage opposite pairs of the rectangular bar members to maintaining the sides of the rectilinear stacked array at a predetermined angle to each other in the general shape of the tray.

  • Patent number: 4650084
    Abstract: A collapsible box having sidewalls secured together at the corners of the box by first and second loop elements fastened to two adjacent sidewalls. As disclosed, each loop element includes two tapered end portions adjacent one another driven into a sidewall, to secure the loop element thereto, and two elongated portions extending along the sidewall from the tapered end portions, terminating in a loop at a corner of the box. The sidewalls of the box meet at the corner to produce a recess, and a fastening wire is passed through the loops of the loop elements on the two adjacent sidewalls, with the ends of the wire twisted together to secure the two loop elements to one another in the recess. The forces produced serve to hold the box together and to hold the loop elements against the sidewalls. The loop elements are also stapled to the sidewalls.

  • Patent number: 4609116
    Abstract: A bulk container which is disassemblable such that the interchangeable wall panels and the locking clips which connect the wall panels fit flatly into the flanged base assembly of the container. A base assembly provided with flanged sides holds the disasembled rectangular side panels. Each side panel is provided with a miter strip adjacent each side edge which extends below the lower edge in a leg. The leg supports the panel above the flange of the base assembly. Adjacent the miter strip at each side of the panel is a short slot. Locking clips engage a pair of panels at each corner by engaging the slots. The size reduction afforded by the disassembled condition of the container provides for more efficient shipping and transportation of the containers. Interchangeable parts reduce overall costs and the time required for assembly and disassembly.
