Patent number: 6003704Abstract: A cleated crate having opposing side panels and opposing end panels, hingedly connected together pairs of opposing inner and outer hinges which define corners in the crate. Each hinge comprises a pair of members having trapezoidal shapes in cross-section which defines a neck surface and an opposing shoulder surface and an oblique surface and an opposing back surface. The elongated members in the inner hinges are disposed in mirrored relation with the necks side-by-side and the oblique surfaces defining a V-shaped channel on a side of the hinge. The members are secured together by a pair of U-shaped staples driven into the butt ends. The members pivot to a second position for bringing the oblique surfaces into bearing contact. The elongated members in the outer hinges are disposed in mirrored relation with the distal edges of the members defined by the respective oblique surface and the shoulder surface in touching contact. The oblique surfaces define a V-shaped channel on a side of the hinge.Type: GrantFiled: June 30, 1998Date of Patent: December 21, 1999Assignee: North American Container CorporationInventor: John M.

Patent number: 5829189Abstract: 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.Type: GrantFiled: September 9, 1997Date of Patent: November 3, 1998Assignee: North American Container Corp.Inventor: John M.

Patent number: 5813555Abstract: 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.Type: GrantFiled: November 17, 1995Date of Patent: September 29, 1998Assignee: North American Container CorporationInventor: John M.

Patent number: 5622306Abstract: 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.Type: GrantFiled: November 9, 1995Date of Patent: April 22, 1997Assignee: North American Container Corp.Inventor: John M.

Patent number: 5096112Abstract: A wood reinforced corrugated paperboard shipping container with interlocking pallet to direct positioning of the container on the pallet and to interlock the container with the pallet. The pallet includes longitudinal runners and cross members. At least one cross member overhangs the side of a lower runner. The overhang portion of the cross member and the side of the runner together define a recess which receives an attaching strip that is connected to a lowermost portion of the wall of the container. In placing the container on the pallet, a beveled upper surface on the overhang portion of the cross member bears against the bottom surface of the attaching strip. The attaching strip thereby moves downwardly and out to move around the outside end of the overhang portion of the cross member and the back into the recess, thereby matingly interlocking the container to the pallet.Type: GrantFiled: October 31, 1990Date of Patent: March 17, 1992Assignee: North American Container CorporationInventor: John M. Grigsby
