A valve assembly for use with a flexible container, in which the valve assembly is anchored to the flexible container. The valve assembly provides for the egress of fluid from the flexible container such that the interior surfaces flexible container do not block or otherwise prevent fluid flow or fluidic communication between the interior of the flexible container and the valve assembly. The portion of the valve assembly within the interior of the flexible container includes a support structure that prevents the walls of the flexible container from collapsing down on, and blocking either completely or in part, fluid flow through the opening of the valve inside of the flexible container.
