  • Container liner system for bulk transfer
    Patent number: 5489037
    Abstract: This invention relates to systems of handling flowable cargo in lined cargo containers. An inflatable, self-installing liner configured to line the container, when inflated, is installed and inflated within the container. A transparent, rigid bulkhead keeps the filled liner from transferring load directly to access doors to the container. Special inflatable bags are provided between the liner and the container at positions where cargo tends to remain during unloading of the liner.
