A technique is described whereby liquid dispensing systems and containers which house materials sensitive to oxygen are equipped with a flexible bladder-like material and a one-way valve. As the material within the container is dispensed, the one-way valve arrangement enables the flexible bladder to collapse, preventing air from entering the container.
