Abstract: An adapter is configured with two base platforms, initially tethered together, that separately receive a dispensing tube and attached to a standardized spout fitment at opposite ends. In use, the platforms collapse and lock together, while simultaneously creating an outwardly bellowing section in the tube that can double as a sealing gasket. The adapter is sized to couple to existing spout fitments and tube sizes to allow for easy adoption, while its components may all be constructed from the same polymeric material to facilitate manufacturing and/or recycling.

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.

Abstract: The present invention relates generally to a valve for a flexible plastic container and more particularly to a valve for dispensing particulate containing liquids.
