Abstract

A fluid storage container includes an inner vessel part having a first interior space (S1) for storing a fluid, an outer vessel part having a second interior space (S2) that accommodates the inner vessel part and spaced apart from the inner vessel part outwards, and a suspension part provided between the inner vessel part and the outer vessel part, one side of which contacts the inner vessel part, and an opposite side of which contacts the outer vessel part. The suspension part includes an inner member, one end of which is coupled to the inner vessel part and which extends from the one end thereof outwards, and an outer member, one end of which is coupled to the outer vessel part, which extends from the one side thereof inwards, and coupled to the inner member. The outer member is formed of a material having a thermal conductivity that is lower than that of the inner member.

First claim

What is claimed is:

1. A fluid storage container comprising:
an inner vessel part having a first interior space for storing a fluid;
an outer vessel part having a second interior space that accommodates the inner vessel part, the outer vessel part being spaced apart from the inner vessel part outwards; and
a suspension part provided between the inner vessel part and the outer vessel part, one side of the suspension part contacting the inner vessel part and an opposite side of the suspension part contacting the outer vessel part,
wherein the suspension part comprises:
an inner member, one end of which is coupled to and extends outward from the inner vessel part; and
an outer member, one end of which is coupled to and extends inward from the outer vessel part, the outer member being coupled to the inner member, and
wherein the outer member is formed of a material having a thermal conductivity that is lower than that of the inner member.

2. The fluid storage container of claim 1 , wherein a thermal expansion coefficient of the outer member is higher than a thermal expansion coefficient of the inner member.

3. The fluid storage container of claim 1 , wherein the inner member comprises a metallic material, and
wherein the outer member comprises a polymer material.

4. The fluid storage container of claim 1 , wherein a recessed area having a recessed shape is formed in an area of the outer member that faces the inner member, and
wherein the inner member is inserted into the recessed area of the outer member.

5. The fluid storage container of claim 4 , wherein a first planar section is formed at a portion of a circumferentially outer surface of an area of the inner member that is inserted into the recessed area, and
wherein a second planar section having a shape corresponding to the first planar section is formed in an area of an inner surface of the recessed area, which faces the first planar section.

6. The fluid storage container of claim 4 , wherein a first convex-concave section protruding outwards or recessed inwards is formed at the portion of the circumferentially outer surface of the area of the inner member, which is inserted into the recessed area,
wherein a second convex-concave section having a shape corresponding to the first convex-concave section is formed in an area of an inner surface of the recessed area, which faces the first convex-concave section, and
wherein any one of the first convex-concave section and the second convex-concave section is inserted into the other one of the first convex-concave section and the second convex-concave section.

7. The fluid storage container of claim 1 , wherein the inner vessel part comprises:
an inner body defining the first interior space; and
an inner coupling area provided on one side of the inner body, into which the inner member is inserted and coupled thereto, the inner coupling area having a shape corresponding to the inner member.

8. The fluid storage container of claim 7 , wherein a first planar part is formed in an area of a circumferentially outer surface of the inner member, the first planar part being inserted into the inner coupling area, and
wherein a second planar part having a shape corresponding to the first planar part is formed in an area of an inner surface of the inner coupling area, which faces the first planar part.

9. The fluid storage container of claim 7 , wherein a first convex-concave part protruding outwards or recessed inwards is formed in an area of a circumferentially outer surface of the inner member, which is inserted into the inner coupling area,
wherein a second convex-concave part having a shape corresponding to the first convex-concave part is formed on an inner surface of the inner coupling area, and
wherein any one of the first convex-concave part and the second convex-concave part is inserted into the other one of the first convex-concave part and the second convex-concave part.

10. The fluid storage container of claim 7 , wherein the inner coupling area has a shape protruding from the inner body toward the inner member.

11. The fluid storage container of claim 7 , wherein the inner coupling area has a shape recessed from the inner body into the first interior space.

12. The fluid storage container of claim 7 , wherein the outer vessel part comprises:
an outer body defining the second interior space; and
an outer coupling area provided on one side of the outer body, into which the outer member is inserted and coupled thereto, the outer coupling area having a shape corresponding to the outer member.

13. The fluid storage container of claim 12 , wherein the suspension part comprises a first suspension part and a second suspension part, and
wherein one or more of the first suspension part and the second suspension part are movable with respect to the inner coupling area or the outer coupling area.

14. The fluid storage container of claim 13 , further comprising: a pipeline member coupled to one side of the inner vessel part, in communication with the first interior space, and provided adjacent to the first suspension part,
wherein the first suspension part is fixedly coupled to the inner coupling area or the outer coupling area.

15. The fluid storage container of claim 12 , wherein the suspension part further comprises
a spring member provided in the outer coupling area and provided between the outer body and the outer member.

16. The fluid storage container of claim 1 , wherein the suspension part further comprises a ring member surrounding an outer peripheral surface of the outer member; and
wherein the outer member further comprises a protruding area having a shape that extends along a circumferential direction of the outer member on an outer peripheral surface of the outer member and provided between the ring member and the outer vessel part.

17. The fluid storage container of claim 5 , wherein a cross-section of the inner member, obtained when the first planar section is cut perpendicularly to the first planar section, has a polygonal shape, and
wherein a cross-section of the outer member, obtained when the second planar section is cut perpendicularly to the second planar section, has a polygonal shape.

18. The fluid storage container of claim 8 , wherein a cross-section of the inner member, obtained when the first planar part is cut perpendicularly to the first planar part, has a polygonal shape, and
wherein a cross-section of the inner vessel part, obtained when the second planar part is cut perpendicularly to the second planar part, has a polygonal shape.
