Abstract: A flexible container filling device adapted to quickly fill sandbags for water control, erosion control and military use is comprised of a vehicle coupling mechanism, a hopper having at least one inlet port and at least one outlet port and a flexible container receiving system. The flexible container receiving system includes at least one flexible container ejection device. Furthermore, the flexible container receiving system is adapted to receive at least one flexible container. The receiving system is then adapted to receive flexible container filler material from the hopper. The receiving system places the flexible container filler material within the flexible container and ejects the flexible container from the system upon the flexible container being at least partially filled. This apparatus also provides a method for emptying the flexible container, collecting the flexible container material and collecting it for reuse.
