An apparatus (10) receives an at least partially flexible vessel (14) adapted for receiving a fluid. The apparatus (10) may include an overpack (12) and a partition (16) removably positioned in an interior of the overpack (12). The partition (16) may extend generally transverse to a sidewall (12b) and generally aligned with a floor (12c) of the overpack (12) to form a compartment for receiving the vessel (14). The partition (16) may also form part of a carrier (17) for the vessel (14). A filling station for filling containers (10) is also disclosed, as are related methods.
