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.
