A three part container system. The first part is an outer rigid container formed with a mouth defining an opening into the outer container. The second part is an inner container positioned within the outer container, the inner container formed with a mouth defining an opening into the inner container, the mouth of the inner container being positioned in and sealed to or adjacent to the mouth of the outer container, at least a portion of the inner container being collapsible so that the inner container can be filled with a liquid. The third part is a turret fitted directly or indirectly by way of the outer container to the mouth of the inner container. The turret contains a one way valve so that if the inner container contains a liquid and the collapsible portion of the inner container is held above the turret, the fluid in the inner container will flow through the one way valve and out of the mouth of the turret as the inner container collapses within the outer container.
