  • Intermediate bulk container spill pallet
    Patent number: 6382108
    Abstract: A spill pallet for supporting and providing secondary containment for at least one intermediate bulk container. The spill pallet consists of a base and side walls that form an open-top box structure. From the base of each of the four corners of the structure extend four pillars with flat upper surfaces. These pillars support a platform that covers a substantial portion of the structure. The platform contains a center support post that extends to the base of the structure. The container and platform have been adapted so that they can be nested with other containers and platforms for shipping.
