  • Patent number: 6189778
    Abstract: A robust, stackable container for shipping goods and for displaying and dispensing the goods at the point of purchase is disclosed. The container has a pull-out panel comprising a portion of a side wall panel which is manually openable to display and dispense the goods. The pull-out panel is defined by a separation line in the wall panel formed by a plurality of perforations and is hingedly attached to the container. Wing flaps located on each end of the pull-out panel extend between the pull-out panel and the container providing side partitions preventing the goods from spilling out of the container when opened. The container wall panels are reinforced with reverse folded reinforcing flaps which strengthen the container to prevent crushing and bursting when stacked. The container is formed from die cut blanks into a knockdown state which can be assembled into the container and filled by automated processes.

  • Patent number: 6116498
    Abstract: An open-top fold-and-glue container is provided a collapsed or knocked-down-flat configuration and can be erected into a nested stacking frusto-pyramidal configuration in which the container walls are inclined outwardly and an upper container is supported on self-erecting shoulders in a lower container in the stack. The container has a bottom integral with opposite end walls and side walls, the end and side walls each being formed of an inner panel folded downwardly against an outer panel. The shoulders are located in the inner panels of the end walls, and are self-erecting in the manner of an expanding parallelogram between upper and lower glue strips and a support strip projecting substantially vertically downwardly from the shoulder to the bottom. The attachment of the upper glue strip to the outer panel of the end wall forms a reinforcement at the rim. The ledge is disposed adjacent to and under this reinforcement, and a manual grip can be placed immediately under the ledge.

  • Patent number: 6092720
    Abstract: A dish-shaped container is made from a folded cardboard blank sealable on both sides. The container has a rectangular bottom and four upfolded lateral panels which are connected to the container corners respectively by four triangular-shaped corner panels. A circumferential double-walled outer flange parallel to the bottom consists of first and second outer strips. The first outer strips are folded on the respective lateral panel, and the second outer strips are aligned with their cut edges towards the outer surface of the respective lateral panels. The first outer strips extend continuously over the entire periphery of the container, so that there are no breaks up to the filler area. The second outer strips are left out in the area of the corner panels. As a result of the double layer, the container comprises a reinforced outer flange and is in addition absolutely impermeable to liquids in the corner areas.

  • Patent number: 5579991
    Abstract: A container for displaying and transporting a heavy product, such as a vanity top, is fabricated and assembled as an integral unit to secure the product against possible damage while permitting the product to be easily transported and viewed by prospective purchasers. Each of its pair of side wall panels has an elongated central flap section which is hinged and folded inwardly to define a generally front-facing double fold front surface for the container slanted in a front and back direction and elongated in a direction generally transverse to the top and bottom wall panels. An upper end flap hinged along an upper edge of each side wall panel is at least in part folded inwardly in spaced generally parallel relation to the side wall panel, defining a surface extending generally transverse to the top and bottom wall panels to block movement of the product toward the back panel. Central, upper and lower pairs of overlapping rounded tabs are cut in the side wall panels and in the intermediate flap sections.

  • Patent number: 5423449
    Abstract: A package particularly useful for either conventional oven or microwave heating of refrigerated or frozen foodstuffs includes a lower paperboard tray, an upper frangible paperboard cover, and an intermediate compartmentalized plastic food tray. The bottom of the plastic tray food compartments rest on the tray bottom. The plastic tray side edges are clamped between laterally extending side flanges on the lower tray and edges of the top cover. The top cover is removed by ripping along tear lines. After consumption of the food, the plastic tray is readily removed to thereby facilitate separation for recycling. The package construction also facilitates the use of relatively thin plastic for forming the compartmentalized plastic tray because the weight of the foodstuffs in the plastic tray components is partially borne by the lower tray.
