Abstract: The present application relates to a system for evacuating fluid from a flexible container. The system includes a spout connected to a flexible container. 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.

Abstract: A present application relates to a valve assembly for use with a liquid container. The valve assembly includes a spout containing an opening to the liquid container, the spout being configured to form a liquid-tight seal with a housing. A sleeve extends through the housing toward the liquid container through the opening. A valve is secured to the housing and extending into the opening through the sleeve and forming a liquid-tight seal with the sleeve. The valve includes a body portion with a cutaway section and a leg fixed to the valve by a hinge, wherein the leg is configured to flex outwards against the sleeve upon insertion of a tube into the valve causing the cutaway section to open a flow channel to allow liquid to flow through the valve assembly.

Abstract: A duckbill valve includes a flexible and hollow body having a first shape upon being formed by injection molding. The body in the first shape has a first opening at a first end and a second opening at a second end. The body is configured to be inverted into a second shape. The second shape has a first opening at a first end and has a slit at a second end. The slit is defined by lips that are pressed together to form a seal.
