spout 10 the pivotal connection 30 of the evacuation structure 26 allows it to flex away from the spout 10 when the flexible container 12 is filled with fluid this is shown by the direction of arrow a in fig3 thus the pivoting of the evacuation structure 26 ensures the evacuation structure 26 will not obstruct the flow of the fluid inhibiting the filling of the flexible container 12 in addition because the evacuation structure 26 is flexibly movable it will not break off under the force of the fluid during filling during evacuation of the fluid the evacuation structure 26 will pivot back towards the spout 10 ensuring that the walls 16 of the flexible container 12 will not inhibit the fluid from evacuating the flow of the evacuating fluid will cause the evacuation structure 26 to return to its original position or close enough to the spout 10 so the evacuation structure 26 will prohibit the walls 16 of the flexible container 12 from blocking the spout 10 during evacuation alternatively in another embodiment of the present invention the pivotal connection 30 will have memory after filling and before evacuation of the flexible container 12 the memory of the pivotal connection 30 will cause the evacuation structure 26 to pivot back towards the spout 10 the evacuation structure 26 will prohibit the walls 16 of the flexible container 12.
