  • Patent number: 5769003
    Abstract: A twin sheet, thermoformed beer keg pallet has a load platform reinforced by parallel ribs formed inwardly from the bottom sheet. Rib ridges are thermally fused to the platform top sheet. Stiffener pockets in the shape of truncated pyramids are formed from the top sheet between the rib ridges. Pocket bottoms are fused to the bottom sheet. Pocket sidewalls are thermally fused to adjacent rib side walls. The platform ribs have a progressively greater depth between the platform top sheet and bottom sheet along the rib length from the pallet center plane outwardly in opposite directions. When loaded and lifted by a fork truck, the platform flexes about an axis in the center plane to tilt the tops of the kegs on the pallet inwardly to the center.
