  • Patent number: 5484241
    Abstract: A void filler device for use in staggering paper rolls during shipment includes a housing member which generally surrounds an inner core. The housing member has a top wall, a bottom wall, and side walls which are attached to the core, and is octagonally shaped. The top and bottom walls of the housing include fold lines around which the walls are folded to collapse the void filler device. The inner core member includes a plurality of flat boards made of laminated paperboard, corrugated cardboard, plastic or other like suitable material. Each of the boards has spaced notches along its length and the boards are interconnected with each other along the notches to form an open cell construction that is expandable and collapsible. The top and bottom walls can include apertures therein for ensuring that the paper rolls are properly aligned.

  • Patent number: 5413823
    Abstract: A roll riser for use such as in staggering paper rolls during shipment generally includes first and second deck sheets each having inner and outer sides, a fold line along the edge of the core and a fold line along its midpoint, and are connected together by an open-celled core. The roll riser is collapsible along the fold lines for shipment to the user or for storage so as to occupy a relatively small amount of space and then expanded by the user for use. In a first embodiment, pressure sensitive tape is secured to the inner sides of the sheets and when the roll riser is in an expanded configuration, the tape adheres to the core. In a second embodiment, pressure sensitive tape is secured to the outer side of the first sheet and when the roll riser is in an expanded configuration, the tape is adhered to the outer sides of the first and second sheets. In each embodiment, the tape causes the roll riser to remain in the expanded configuration so as to prevent the roll riser from collapsing.

  • Patent number: 5413824
    Abstract: A roll riser for use, such as in staggering paper rolls, during shipment generally includes a rigid sheet and a core attached by its ends to the sheet along the length of the sheet. The core is collapsible and expandable so as to transform the roll riser from a collapsed configuration to an expanded configuration. First and second end portions of the sheet are folded against a side of the core around fold lines, and lie generally adjacent to the core to cause the roll riser to remain in an expanded configuration.

  • Patent number: 5409755
    Abstract: An inverted V-shaped bulkhead void filler for filling empty spaces in a cargo area during shipping includes a novel non-pivotable, but disengagable, interlocking structure. The bulkhead void filler includes first and second rigid panels of a sandwich-type construction attached by the interlocking structure at an upper end of each of the panels. To form the novel non-pivotable, but disengagable, interlocking structure, the second panel includes a side clip and end clips attached to its upper end. The clips define a gap substantially equal to the width or thickness of a leg of the core. The leg of the core of the first panel is slid into the gap and held securely therein.

  • Patent number: 5395191
    Abstract: A collapsible and expandable void filler for separating cargo during transit in trucks, railroad cars, airplanes and the like includes an outer tubular housing having a diamond-shaped tubular core. The housing and core are collapsible into a generally flat configuration along score indentations. In one embodiment, the void filler is held in an expanded configuration by a plurality of collapsible wall portions along the outer housing that collapse inwardly from the periphery of the housing and engage the core. In other embodiments, the void filler is held in an expanded configuration by a cord or elastomeric bands which are tightly stretched around the periphery of the housing and is held in a series of aligned notches.

  • Patent number: 5082244
    Abstract: A cargo air bag inflation valve and inflator combination comprising a tubular plastic valve body having a central passageway for the flow of compressed air to permit the inflating of an air bag. Valve closure means is reciprocal in the passageway and is biased to a normal valve closed position. A quick connect/disconnect fitting carries detent balls operative to engage a circumferential edge on the valve body and to snap onto a detent ball receiving surface of diameter less than the circumferential edge to thereby draw the valve body into the fitting. An annular shoulder in the fitting engages the valve plug separating the valve seat carried by the valve body from the valve plug permitting inflation of the air bag through the fitting and central passageway.

  • Patent number: 5042541
    Abstract: An inflation nozzle for inflating cargo air bags having a main body through which compressed air flows to an outlet in a nozzle tip and a handle pivoted to the main body carrying at its end adjacent the nozzle tip a spring-loaded closure for closing off the outlet when the inflation nozzle is out of engagement with the cargo air bag valve. The body and handle are spring loaded whereby the handle can be squeezed and slid into engagement with the air bag valve; and, on release, the nozzle tip protrudes into the air valve opening it and completing locking of the nozzle to the valve.

  • Patent number: 5042665
    Abstract: A rigid, lightweight, splinter-free packaging frame for shipping pallet loads of goods having four marginal side members having a width and length corresponding generally to the width and length of the pallet load upon which it is to be used, the side members comprising a core of corrugated board folded upon itself and having a length of solid fiber laminated linerboard laminated to the opposed outer planar faces of the corrugated board. The linerboard extends beyond one end of each of the side members and receives the opposite end of an adjoining side member and is adhered thereto to form a rigid right angle frame.
