A passageway within the spout is in fluid communication with an inside of the flexible container, and the passageway has a top end and a bottom end. An evacuation facilitating structure is positioned proximate the bottom end of the passageway and has a fluid channel therethrough. The evacuation facilitating structure blocks portions of the wall of the flexible container from entering the bottom end of the passageway and preventing fluid from evacuating the container via the passageway.
