Abstract
A liquid dispenser for dispensing a consumable liquid from a container. The dispenser includes a cabinet configured to receive one or more containers in an inverted position such that liquid is induced by gravity to flow out of an open interior of the container though a dispensing opening. A positive pressure valve assembly is mounted to the dispensing opening of the container prior to insertion of the container into the cabinet. The valve assembly includes a cap connected to the dispensing opening and a discharge tube extending from the cap. A flow restrictor of the valve assembly is positioned to selectively open and close the discharge tube to control the flow of liquid from the container. A one-way valve is positioned between the open interior of the container and a supply of air. The one-way valve allows air flow into the container as the fluid is discharged to maintain a positive pressure within the container.
