Abstract:
1. A container system, comprising: an outer container of substantially fixed shape formed with a mouth defining an opening into the outer container; 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; a turret fitted directly or indirectly by way of the outer container to the mouth of the inner container, the turret comprising a one way valve in liquid communication with the mouth of the inner container by way of a passageway in the turret, the turret defining a mouth in liquid communication with the one way valve by way of a passageway in the turret so that if the inner container contains the liquid and the collapsible portion of the inner container is held above the turret, the liquid 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, and so that if the turret is held above the inner container, flow of air back into the inner container is substantially prevented by the closure of the one way valve wherein the mouth of the inner container is of fixed shape having external threads and wherein the mouth of the outer container has internal threads dimensioned to engage the external threads of the mouth of the inner container.
