What is claimed is: 1. A liquid container comprising: a sealing wall configured to directly contact liquid contained in the container; a structural wall comprising an exterior wall of the liquid container or an inner structure integrated with the exterior wall; a plurality of connectors mechanically connecting the sealing wall and the structural wall, the plurality of connectors comprising a first connector; an intermediate wall structure positioned between the structural wall and the sealing wall, the intermediate wall structure comprising a first layer, a second layer and a sealing layer positioned between the first and second layers; and a sealing plate liquid-tightly connected to both the first connector and the sealing layer; wherein the intermediate wall structure is configured to move relative to at least one of the sealing wall and the structural wall, wherein at least one of the sealing plate and the sealing layer comprises at least one corrugation. 2. The container of claim 1, wherein the intermediate wall structure comprises a surface facing the sealing wall, wherein the sealing wall comprises a surface facing the intermediate wall structure, and wherein the surface of the intermediate wall structure is slidable with reference to the surface of the sealing wall. 3. The container of claim 1, wherein the intermediate wall structure is configured to slide with reference to the sealing wall and the structural wall. 4. The container of claim 1, wherein the intermediate wall structure is mechanically connected to the plurality of connectors, and wherein the mechanical connection between the intermediate wall structure and the plurality of connectors allows the intermediate wall structure to move relative to the plurality of connectors. 5. The container of claim 1, wherein the intermediate wall structure has a plurality of through holes, and wherein each connector passes through each through hole. 6. The liquid container of claim 1, wherein the intermediate wall structure has a plurality of through holes, wherein a first one of the plurality of through holes is configured to permit the first connector to pass therethrough. 7. The liquid container of claim 6, wherein the sealing layer of the intermediate wall structure comprises a portion extending into the first connector through hole, and wherein the portion is configured to substantially liquid-tightly connect with the sealing plate. 8. The liquid container of claim 7, wherein the portion is further configured to stretch and shrink in a direction of the movement of the intermediate wall structure relative to the at least one of the sealing wall and the structural wall. 9. The liquid container of claim 6, wherein the sealing plate comprises a portion extending into the first through hole, and wherein the portion of the sealing plate is configured to substantially liquid-tightly engage with the sealing layer of the intermediate wall structure. 10. The liquid container of claim 9, wherein the portion is further configured to stretch and shrink in a direction of the relative movement of the intermediate wall structure. 11. The liquid container of claim 1, further comprising a coupler liquid-tightly connecting the sealing plate and the sealing layer.
