Patent number: 7229003Abstract: A reinforced bulk materials container having a first wall-forming blank scored to provide main panels foldably joined together at a plurality of corners with each main panel having a foldably joined bottom flap. A wear reducing member attaches along the score for the bottom flaps and overlaps lateral portions of the flaps and the panels. A second wall-forming blank of corrugated paperboard defining panels laminates to the first wall-forming blank and includes members fixedly attached about a perimeter of each panel and a filler pad within the perimeter defined by the members. The wear reducing member resists the bottom edges of the container from wearing through caused movement of the container on rough surfaces.Type: GrantFiled: November 30, 2004Date of Patent: June 12, 2007Assignee: North American Container Corp.Inventors: John M. Grigsby, Jr., Jeffrey C. Banks

Patent number: 6938557Abstract: A top and end frame assembly (10) attachable to a pallet (12) for packing, shipping, and storing heavy articles, with a pair of stringers (20) made with open-sided U-shaped channels and connected together by transverse members (22, 24). Two pairs of opposing corner posts (50) each formed of an open-sided U-shaped channel pivotally attach at respective opposing distal ends of the stringers (20). Each corner post (50) moves between a folded position with the corner posts received in the respective stringer for shipping in a knocked-down position and an extended position for attaching to a pallet for a frame container. Two pairs of opposing side diagonal members (36) pivotally attach to a respective one of the stringers and move between a received position within the stringer and a diagonal position for pinning at an opposing end to a respective one of the corner posts. The corner posts being pivoted to the extended position attach at distal ends to the pallet (12) for containing heavy equipment.Type: GrantFiled: January 24, 2003Date of Patent: September 6, 2005Assignee: North American Container CorporationInventor: John M. Grigsby, Jr.

Patent number: 6585126Abstract: 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.Type: GrantFiled: December 11, 2001Date of Patent: July 1, 2003Assignee: North American Container CorporationInventors: John M. Grigsby, Sr., John M. Grigsby, Jr., Carl D. Prentice, Pete Darmer

Patent number: 6578758Abstract: A container for leaf product and other bulk pack materials wherein a blank of corrugated paperboard is scored to define side walls of the container, and a field of passageways are defined in at least one side wall of the container by a conical pin punch-pressed from opposing sides of the blank to define a passageway for communication of moisture from the container to the atmosphere for drying and long term storage of the leaf products. A method of defining passageways in the blank of paperboard is disclosed.Type: GrantFiled: November 26, 2001Date of Patent: June 17, 2003Assignee: North American Container Corp.Inventors: John M. Grigsby, Jr., Jeffrey C. Banks

Patent number: 6293398Abstract: An elongate member with a first hook at one end and a relatively sliding hook received on the elongate member are disposed in opposing relation for securing a durable good such as a riding lawn mower to a pallet. The sliding hook attaches to a sleeve in order to move relative to the first hook. A nut engages a threaded portion of an opposing end of the elongate member to bear against the sliding hook to secure it in position. The first hook engages a portion of the pallet, and the sliding hook engage a portion of the durable good received on the pallet. The nut restrains the sliding hook from moving away from the first hook, and thereby securing the durable good to the pallet. A wood-cleated corrugated paperboard body is received on the pallet to enclose the durable good. A method of securing a durable good such as a riding lawn mower to a pallet is disclosed.Type: GrantFiled: March 22, 2000Date of Patent: September 25, 2001Assignee: North American Container CorporationInventor: John M. Grigsby, Jr.

Patent number: 6126067Abstract: A container for leaf product and other bulk pack materials wherein a first blank of paperboard is bonded to a second blank of paperboard. A field of bores are defined in at least one side wall of the container by a high-speed non-fluted drill for communication of moisture from the container to the atmosphere for drying and long term storage of the leaf products.Type: GrantFiled: July 21, 1998Date of Patent: October 3, 2000Assignee: North American Container CorporationInventors: John M. Grigsby, Jr., Jeffrey C. Banks

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. Grigsby, Jr.

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. Grigsby, Jeffrey C. Banks, John M. Grigsby, Jr.
