Claim:
1. A volumetricly changeable liquid reservoir system comprising: a reservoir configured to constrain a liquid, at least one or more pathways for air to escape from the reservoir; at least one or more one-way air valves configured to allow air to flow in one direction, wherein the one direction is to escape out one or more of the pathways when the reservoir is compressed; at least one or more float valves configured to work cooperatively with the at least one or more one-way air valves in order to allow air to escape out the one or more pathways but to seal the one or more pathways once substantially all the air is removed from the reservoir; and an outer container configured to support the reservoir and wherein the outer container is a foldable box and wherein the box is configured to allow access by a user in order to apply a compressive force to the reservoir.
