  • Combined product shipping and display unit
    Patent number: 5251753
    Abstract: Shipping/display units include a number of vertically stacked product-containing trays supporting upright dividers which maintain separation between the product containers. When in its shipping condition, the bottom-most tray is nestably received within a pallet skirt which rests upon a conventional wooden shipping pallet. Each tray is provided with an individual corner support member which extends between an adjacent pair of vertically separated trays. A corner post extending the entire height of the unit is positioned at each corner of the unit to provide additional structural support during shipping. To further enhance the aesthetic appeal of the display the pallet skirt may be reverse folded so as to lie against respective vertical sides of the pallet and is maintained in that position by cooperating locking tongues and slits formed in the pallet skirt side walls.
