However, despite the multiple thickness of the corner assemblies, the panels are only adhered in one location per corner. The single adhesion/corner arrangement provides a multi-wall corner arrangement that is strong, yet has flexible applications. The single adhesive/corner adds vertical stacking strength and lateral stability between the panels. The unique approach of only adhering at one place per corner is a space and cost saving improvement that maintains a container integrity and usefulness.Type: GrantFiled: June 30, 2005Date of Patent: February 10, 2009Assignee: International Paper CompanyInventor: Jack A.

Patent number: 7458503Abstract: A stackable container for carrying produce. The container has tapered side walls or end walls to aid in the stacking of like containers. Also, the container has locking flaps that allow the container to be erected manually and without the need for fasteners. Further, at least one tapered wall of the container has a reinforcement flap that creates a partial top structure in the upper part of the container that helps prevent bulging of the walls. The reinforcement flap also creates doubled stacking tabs and diagonal corner posts that aid in the stacking of like containers.Type: GrantFiled: July 25, 2007Date of Patent: December 2, 2008Assignee: International Paper CompanyInventor: Stanley L Fry

Patent number: 7455179Abstract: A shipping box (11), shipping box and pallet assembly (10), and a blank (B1, B2, B3) for making the shipping box. The box has integral attaching tabs (38) projecting downwardly therefrom, with at least one slot (31, 32) therein for receiving an extended end (41) of at least one slat (40) on a pallet (13), to releasably attach the box to the pallet. A reinforcing insert (70) is placed in the box against opposite walls. The insert has a center panel (77) of the same width and height as the box wall against which it is placed, and double thickness end panels (78) at opposite sides of the center panel, extending perpendicular to the center panel and lying against adjacent box walls.Type: GrantFiled: October 27, 2006Date of Patent: November 25, 2008Inventors: Timothy L. Bringard, Eric J Oberliesen

Patent number: 7293694Abstract: An elongate, rectangular box (12, 14, 40, 60, 70, 90, 100) and method for packaging containers (C), wherein the box can be cross-stacked for stable stacking of the boxes, and optimizes utilization of pallet space. Containers (C) are placed in the box in nested, offset relationship in a parallelogram shaped arrangement, and in one embodiment interior corner panels (20, 21) extend angularly across two diagonally opposite corners of the box, defining an interior box shape closely conforming to the parallelogram-shaped arrangement of the containers. The corner panels may be cut from the side walls (18, 19) and folded inwardly and secured at a free edge (28) to an adjacent end wall (16, 17), defining openings (22, 23) in the side wall through which the containers are visible. Side wall segments (24, 25, 26) at the bottom and sides of the opening, in cooperation with the corner panels, retain the containers in place in the box. The box is especially suited for packaging four one-gallon containers.Type: GrantFiled: March 12, 2004Date of Patent: November 13, 2007Assignee: International Paper CompanyInventor: Charles P Weimer, Jr.

Patent number: 7246737Abstract: The box, which can be made from a single sheet or from five separate pieces which are fastened to one another to form the box, is such that at the front ends, extensions project with transverse folding lines to form corner reinforcements. The extensions that form these reinforcements present four folding lines that define the sectors, which form an initial sector which is attached to the inner face of the side, a second sector with a diagonal disposition, a third sector which is attached on the inside of the front, a fourth sector which lies at right angles to the diagonal sector, and a last sector which is attached to one of the two halves of the inner face of the diagonal sector. At their upper edge the sectors present flanges which form projections perpendicular to one another, for positioning in matched opposing notches when the boxes are stacked.Type: GrantFiled: November 14, 2002Date of Patent: July 24, 2007Assignee: Videcart, S.A.Inventor: Pedro Teixidor Casanovas
