A shipping container includes a main insert, a top cover and a cardboard or corrugated shell. The container is especially adapted for securing computer disk drives therein. Potential damage to the disk drives is minimized by isolating movement of the disk drives within the container. Each drive is loaded within a compartment defined by surrounding dividers formed on both the top cover and main insert. The overall container height is minimized by incorporating recesses in the inserts that can increase the effective height of exterior cushioning ribs thus reducing the thickness of the floorboard or base member. The incorporation of the recesses results in formation of relatively thin web sections that interconnect base portions of the cushioning ribs to base portions of the dividers.
