A depletion device of a bag-in-box container for viscous ink comprises an elongated tube extending into the bag. The tube is preferably cylindrical and has a plurality of holes in its side wall. The holes are arranged in columns so as to define longitudinal ribs in the side wall of the tube. Holes in adjacent columns are offset relative to one another. The depletion device maximizes the amount of ink that can be extracted from the bag by preventing the collapsing bag closing off the depletion device.
