Abstract
System for storing and transferring liquid comprising a container for storing liquids, a delivery tube assembly for drawing liquids from said container and transferring said liquids to a second vessel, and, disposed at one end of the delivery tube assembly, a shut-off valve that comprises a casing having a first opening at one end thereof for allowing liquid to enter said casing, a valve head which is normally covering said opening, and a device for biasing said valve head toward said first opening in order to cover same. The container has an actuating device, e.g. a projection, formed on or near the bottom portion thereof, which device actuates the valve head to allow the shut-off valve to open, thereby allowing liquid to be drawn into the first opening in the casing, pass through the casing, and then pass through a second opening in the casing to enter the delivery tube assembly. When the delivery tube assembly and shut-off valve are removed from the container, the valve head closes over said first opening, thereby preventing residual liquid present in the delivery tube assembly from leaking from the tube.
