  • Patent number: 7387215
    Abstract: A frame container (10) for packing heavy durable goods in which a base (12) includes two end frames (14, 16) connected by pairs of opposing side diagonals (40) pinned at first ends to the base and at second ends (42) to the end frames. Each pair of opposing side diagonals (40) pivot between a first position aligned with the base and the second ends near respective ends of the base and an erected second position whereby the side diagonals are disposed at an oblique angle relative to the base with the second ends of the pair of side diagonals remote from the respective ends of the base for enclosing heavy durable goods within the container.

  • Patent number: 7011223
    Abstract: A frame container (10) for packing, shipping, and storing heavy durable goods in which a supporting base (12) includes two pairs of opposing side diagonals (40) with opposing end frames (14, 16) pivotally connected to respective second ends (42) of the opposing side diagonals (40). Each pair of opposing side diagonals (40) pivot between a first position aligned with the base (12) and the second ends (42) near respective ends of the base and a second pivoted position whereby the side diagonals are disposed at an oblique angle relative to the base with the second ends of the pair of side diagonals remote from the respective ends of the base and towards the opposing end of the base.

  • Patent number: 6585126
    Abstract: A returnable crate (10) for heavy durable goods in which a base frame (12) includes stringers (20, 22) secured together by slats (24, 26) and a pair of opposing end frame assemblies (14, 16) that have posts (48) that pivotally connect to respective distal ends of the stringers. Locking collars (90) are slidably received on the posts (48) and move between a locking position and a pivoting position. The locking collars hold the end frame assemblies (14, 16) in a set-up position extending substantially perpendicularly from the base frame (12) and a pivoted position with the end frame assemblies folded down towards the base frame. Side diagonals (58) connect between pivot brackets (52) and the posts (48) in the end frame assemblies (14, 16). The locking collars (90) and side members (58) hold the end frame assemblies (14, 16) in the set-up configuration for shipment of the heavy durable good.

  • Patent number: 6250050
    Abstract: A packing container for enclosing heavy durable goods for storage and shipping having a base frame for supporting an article to be packaged. A pair of opposing wing-end panels are received at opposing ends of the base frame with each wing-end panel comprising a sheet of corrugated paperboard scored to define an end panel separating two side wing panels. A cleat attaches at each side edge and at the scores on each sheet. The side panels fold as wings to cover portions of the opposing sides of the container while leaving a gap on each side between the side edges of the two opposing side wing-end panels. A top frame is received by the pair of opposing wing-end panels. A method of packaging goods in a container is disclosed.

  • Patent number: 5829189
    Abstract: A hinged-corners unitary collapsible wood cleated crate for packaging heavy goods with a tubular body engaged to a base and top frame. The tubular body is formed of a pair of opposing side frames and a pair of opposing end frames, which frames each have a pair of horizontal rails connected to a pair of vertical side slats at respective overlapping aligned distal ends. Each frame includes at least one diagonal cross-member extending between and attached to the pair of horizontal rails. The side frames and the end frames join together in alternating spaced-apart sequence by a plurality of hinge plates that interconnect one of the pair of vertical slats in one of the side frames with one of the pair of vertical slats in an adjacent end frame. The hinge plates are planar sheets of a weather-resistant material, which are scored to allow the tubular body to knock-down for storage and shipping, and unfold to form a volumed body for packaging heavy goods held on a base.

  • 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: 5622306
    Abstract: A tubular corrugated paperboard shipping container having a rigid base frame, a cleat-reinforced tubular corrugated paperboard body attached thereto, and a top frame. The corrugated paperboard body includes a pair of spaced-apart attaching strips fixed on opposing side wall panels of the body. One of the pair of attaching strips on each panel is disposed in alignment with a member of the base frame. The other one of the pair of attaching strips is positioned on the panel in alignment with the top frame. Staples driven through the paperboard wall and the attaching strips secure the paperboard container to the base frame and to the top frame to ensure against component separation, thereby providing a cleated container with improved structural rigidity. A plastic sheet in the top frame prevents dust and dirt from entry into the container.
