  • Patent number: 6079554
    Abstract: A tray for holding a plurality of beverage containers has a floor with a plurality of container seating areas on its top surface and structure on its bottom surface to enable a plurality of the trays loaded with containers to be stacked on top of one another in stable relationship, yet slid relatively easily on top of one another when desired. Peripheral heel protector bands extend around the periphery of the tray to protect the lower ends of containers from damage, and spacer members project upwardly from the floor between the container seating areas to maintain containers in the tray spaced from one another and prevent displacement of the containers from their seating areas when the tray is tilted. A tray sidewall includes spaced pillars extending upwardly from the periphery of the floor and supporting a top rail at their upper ends.
