Flexible tank with a mixing member

A flexible tank for transporting fluids in a transportation container, the flexible tank defining a tank volume for containing a fluid and comprising:

• a mixing member enclosing a fluid pathway extending across an interior surface of the flexible tank, and
• an inlet valve configured to allow passage of fluid from outside the flexible tank into the fluid pathway,
• wherein the mixing member is conically or frustoconically shaped and reduces in cross sectional area along a longitudinal axis in a direction away from the inlet valve and includes an aperture such that the inlet valve is in fluid communication with the tank volume via the fluid pathway, and
• wherein the mixing member comprises a plurality of apertures wherein the plurality of apertures include:
• a proximate aperture, wherein the proximate aperture is a closest aperture of the plurality of apertures to the inlet valve;
• an end aperture, wherein the end aperture is a farthest aperture of the plurality of apertures from the inlet valve;
• and
• a plurality of middle apertures, wherein the plurality of middle apertures are larger than the proximate aperture and smaller than the end aperture.
