Abstract: An integral, generally rectangular corrugated fibreboard blank folds to form an insert having three air cells for cradling and protecting a product. Two of the air cells stand vertically generally on top of the third air cell at ends thereof. A product rests on the third air cell and is received and captured between the two vertical air cells. The insert, with the product in place, fits into a box where tabs projecting from the insert cooperate with the box to form two more air cells at the opposite ends of the insert.

Two of the air cells stand vertically with the third air cell suspended between them. A product rests on the third air cell and is received and captured between the vertical air cells. The insert, with the product in place, fits into a box where tabs projecting from the insert cooperates with the box to form two more air cells at the opposite ends of the insert.

Abstract: A reclosable container made of a material, such as paperboard, has a locking corner in the form of a two-section bellows panel that V-folds to form a slot between two rounded edges, free of any cut or raw edges. A closure panel folds over an upper edge of the container. Locking tabs at opposite ends of the closure panel fit into the slots. The rounded edges enable multiple openings and closings of the container without damage to either the slot or the locking tab.

The specific product which prompted the invention is a toner cartridge for a printer.

Abstract: A round trip mailer box is formed from a unitary corrugated cardboard blank with a plurality of scored lines for a quick and easy folding of panels to set up the box. The corners of the box are reinforced and strengthened by folding and bracing corner panels. The folding of the box is completed by inserting tabs on two interchangeable and overlapping top panels, one over the other, into cutouts on opposite sides of the box. These overlapping top panels can be interchanged so that when a mailing label is placed on each top panel, the box can be mailed to a recipient and later remailed back to the sender by simply interchanging the relative positions of the top panels. The box is easily secured in its closed position by taping or other closure means at the two inserted end tabs of the box and is easily opened, reclosed and reused.

Abstract: A cardboard box, made from a single cardboard blank, has a slanting upper surface to enable the contents of the box to be clearly seen. Opposed interlocking points are formed along the slanting side edge. When one such box is inverted and stacked on another, the interlocking points come into abutment and keep the boxes from sliding apart. As a result, boxes with truncated triangular cross-section may be stacked and shipped as if they were rectangular in all dimensions.

Abstract: An outer mailing jacket is made from a folded sheet of suitable material, such as corrugated cardboard. The jacket has corner panels for centrally positioning a product enclosed therein. The mailing jacket is especially designed for receiving and supporting phonograph records, without danger that a staple used to close the jacket might damage the record.

Abstract: A single and unitary, generally rectangular blank is preferably made of corrugated cardboard, with a waterproof surface. On the corners of the blank, a pair of triangular panels are brought together, in a V-fold, and into a face-to-face contact. Then, the corner panels are folded over the ends of a box as the four sides of the rectangular blank are raised to form the side and end panels of a five-sided box. A cover panel is integrally joined to one edge of a side panel, to swing down and close the box. While the leakproof box has many uses, it is presently thought that it will primarily be used to ship frozen poultry.
