Abstract:
1. A spout connected in fluid communication to a flexible container, the spout comprising: a base being connected to one of a plurality of walls of the flexible container, wherein the spout is generally centrally disposed on a base, and the spout extends in a perpendicular direction from the base; a passageway having a diameter within the spout in fluid communication with an inside of the flexible container, the passageway having a top end and a bottom end, the passageway being substantially perpendicular to the base; and, an evacuation structure having fluid channels therethrough pivotally connected to the bottom end of the passageway and moveable from a fill position to an evacuate position, the structure being substantially parallel to the base and spanning the entire diameter of the passageway in the evacuate position, the entire evacuation structure pivoting in a same direction away from the spout to the fill position when the flexible container is filled through the spout with fluid and does not span the entire diameter of the passageway, wherein the pivotal connection has a memory such that after filing, the memory causes the structure to pivot back towards the spout ensuring that the walls of the flexible container do not prohibit the fluid from evacuating.
