ABSTRACT:
The present invention is directed to a spout having an evacuation structure for a flexible container. The evacuation structure ensures that the walls of the flexible container do not block the spout of the container during evacuation of fluid from inside the container. The evacuation structure additionally pivots away from the spout during the filling of the container so that the evacuation structure does not impede the fluid entering the container during filling.
