  • Patent number: 5857416
    Abstract: A plastic molded pallet includes a corrugated deck providing structural rigidity to the pallet and forming channels for directing leaking fluid away from drums. The pallet also includes a plurality of troughs for selectively collecting the leaking fluid from the channels. Corner troughs flush with the channels collect the leaking fluid from any channel having the fluid. If a corner trough overflows, mid-section troughs on each side of the corner trough begin to collect the overflowing fluid after the overflowing fluid reaches over the mid-section trough dam. If both mid-section troughs are filled, the leaking fluid then proceeds to the next adjacent corner trough, during which time the leaking drum can still be identified based upon the leakage pattern. After all corner and mid-section troughs are filled, the fluid begins collecting in a center trough. The corrugations in the deck isolate the leaking fluid from the drums, and provide concentric surfaces for supporting different-sized drums.
