Abstract: A system for delivery and refilling a dispenser of potable liquids provides a delivery container with rigid sidewalls and refill liquid containers with flexible sidewalls. Complimentary fitments on the dispenser and refill containers permit leak free docking under ascetic conditions when transferring liquid from the refill container into the liquid dispenser. The refill containers are easy to lift and handle, are used one time only and are then recycled. When empty the delivery container is nestable with others.
