Patent number: 5958171Abstract: A structural member formed from a billet, each member comprising a plurality of elongate corrugated paperboard sheets bonded together with an adhesive and disposed between a top and a bottom cap, each cap comprising at least one ply of a fibreboard sheet, a pair of side caps of a solid fibreboard sheet bonded to respective side faces of the paperboard sheet and to the respective edges of the top and bottom caps. The billet comprises a plurality of structural members each separated by a corrugated paperboard rip-out sheet. A method of manufacture is disclosed in which the billet is built up of structural members and rip-out sheets. The billet is then ripped into planks which are ripped along the rip-out sheets to separate the structural members for use as a substitute member for wood cleats or members.Type: GrantFiled: November 17, 1997Date of Patent: September 28, 1999Assignee: North American Container CorporationInventors: 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. Grigsby, Sr.

Patent number: 5318180Abstract: An insert having a central bottom panel with two end panels and two top flanges foldably connected by spaced-apart scores for forming a U-shape insert that is received by a conventional regular slotted container. A pair of elongate members attach to the bottom panel to provide increased bottom rigidity to the container. A pair of cleats attach to each of the side panels and a lower end of the cleat rests on an upper surface of one of the elongate members. A transverse member attaches to each top flange and is supported on an upper end of the cleats. The transverse member supports a top load on the container and the cleats communicate the top load to the elongate members. An enclosed container is disclosed for holding an article on the elongate members by wrapping the insert and the article thereon with a film.Type: GrantFiled: May 13, 1992Date of Patent: June 7, 1994Assignee: North American Container CorporationInventor: 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
