  • Patent number: 5257734
    Abstract: A waste paper bin of large capacity comprises a base 2 having side walls 5, a bottom wall 4, and a removable lid 3. The bottom wall and the removable lid are each formed by folding a sheet of flexible material. The lid has side walls 11 for overlapping the side walls 5 of the base 2 when the lid is fitted to the base. The bin is formed from an inexpensive sheet material, such as cardboard, so as to be semi-disposable. The bin may be replaced by a fresh bin when it becomes worn, without requiring substantial expenditure. A decorative pattern or motif may be applied to the sheet material.

  • Patent number: 5253800
    Abstract: A one piece pizza tray blank having a generally planar member and a pair of sidewalls capable of being folded upward therefrom. Each of the sidewalls has a pair of opposing extensions capable of being folded inward therefrom along vertical extension fold lines. Each of the extensions has a foot extending downward therefrom in the direction of the planar member. The feet are designed to lockingly engage with slots and pressure tabs in the corner regions of the planar member for lockingly engaging the sidewalls and extensions in a vertical position. The feet also act as supports to prevent the planar member holding a pizza from contacting a counter or table top upon which it may be placed. This pizza tray may be slid inside of an appropriate bag for pizza transport.

  • Patent number: 4676429
    Abstract: An octagonal tray and one-piece blank for forming it. The tray is formed from corrugated paperboard and is provided on at least its interior bottom and wall surfaces with a wax coating. The tray includes vertically disposed posts at its end walls, the posts increasing the vertical stacking strength of the tray and also reducing the requirement that the trays be accurately vertically aligned when stacked one on top of the other. The tray is manually erected by folding along hinge or fold axes formed in the blank. Crushed ice is placed among and on fish or poultry within the tray for example, with the tray then being lidded for shipment.

  • Patent number: 4645122
    Abstract: A container for produce and the like is provided which includes a central section and a pair of end sections affixed thereto. The central section includes a bottom panel, upright side panels arranged in opposed spaced relation, and top closure panels. The bottom and side panels are interconnected by a pair of first joiner panels. The side and top closure panels are interconnected by a pair of second joiner panels. The upper edge portion of each end section is provided with at least one upwardly protruding member. The protruding member and the adjacent edge portion of a corresponding top closure panel are provided with complementary locking elements, the latter coacting to effect locking of the top closure panel in a predetermined folded position. The second joiner panels are disposed in abutting engagement with adjacent edge portions of the end sections, thereby restraining lateral relative movement of the top closure panels when the latter are in said predetermined folded position.

  • Patent number: 4623063
    Abstract: A fibreboard shipping container for coil material, such as wire, is formed of an octagonal cross-section tubular body having a closed bottom and a cover, with an octagon shaped, tubular core coaxially positioned within the body. A pair of stiff, fibreboard panels are forcibly positioned within the container on opposite sides of the core in substantial face to face contact with their adjacent core wall surfaces, and with their opposite vertical edges pressing against their adjacent interior wall surfaces of the body. The panels have closely spaced, horizontal score lines for folding their lower edge portions incrementally upwardly to adjust their heights to correspond to the distance between the cover and the upper surface of the core so as to apply downwards pressure by the cover against the core.

  • Patent number: 4614298
    Abstract: An octagonal container closure in which the bottom closure flaps are held in place while the structural integrity of the flaps is maintained. Locking apertures are placed in opposed side closure flaps. The apertures remove as little material as possible from the side closure flaps and maintain the rectangular shape of the flaps. The apertures are shaped and located to allow the corners of the opposed end closure flaps to protrude through the apertures and to lock behind the side closure flaps. The shape of the apertures provides a two-way lock on each corner of an end closure flap, holding it both in the length and width direction. This provides a firmer closure than has been previously achieved.

  • Patent number: 4607785
    Abstract: A flat of fiberboard in knocked-down form for setting up into a tray which has strengthened corners. The flat consists of laminated strength-producing connecting corner tabs between hinged side-wall forming flaps. The tabs are formed on the ends of the flaps and some of the flaps are provided with angular fold lines which provide foldable sections in these flaps, the fold lines extending from the flap hinge lines of the respective flaps to a point within the flaps and a slit being provided from that point in each flap to the outer edge of the flap to permit folding of the foldable flap sections.

  • Patent number: 4600142
    Abstract: A box or container for yams or other bulk products wherein there are closure panels having lock panels at each end thereof, and which lock panels interlock in lock notches formed in end panels carried by a bottom panel of the box. The relationship between the lock panels, which includes bent elbow hooks, and the lock notches is one wherein the required locking action is easily effected and wherein the locks may be readily released for inspection. The box preferably has a three layer end wall construction including end panels carried by the bottom panel and other end panels carried by side panels of the box. The box is readily stackable and has tapered sides and vent openings so as to permit circulation between and within stacked boxes. In one modification the box is formed from a tube, the tube being formed by joining together the ends of a unitary blank to thereby form a manufacturer's joint, the blank defined by a plurality of hinged, articulated panels.
