A method of forming a vacuum insulated refrigerator cabinet, the method comprising providing first and second sheets of material. The first sheet of material is thermoformed over a first forming tool forming a first intermediate structure. The first intermediate structure is then thermoformed over a second forming mold to create a second intermediate structure. The second sheet of material is then sealing connected with the second intermediate structure forming an annular space. A vacuum is created in the annular space creating a vacuum insulated cabinet.

1. A method of forming a vacuum insulated refrigerator cabinet, the method comprising: providing first and second sheets of material comprising at least a first layer of thermoplastic material that is at least partially permeable to oxygen, nitrogen and water vapor, and a second layer of material that is substantially impermeable to oxygen, nitrogen and water vapor;heating at least a portion of the first sheet of material to a temperature at which the first sheet of material can be plastically deformed;utilizing a first forming tool to deform the first sheet of material and form a first intermediate structure having a base sidewall defining a generally quadrilateral perimeter and four first sidewalls extending transversely from the quadrilateral perimeter to define a cavity having an opening that opens in a first direction and defines a peripheral edge extending around the opening;providing a second forming tool having sidewall portions defining four generally rectangular outwardly facing surfaces and four generally rectangular inwardly facing surfaces, and an end surface extending transversely between the inwardly and outwardly facing surfaces;disengaging the first intermediate structure from the first forming tool, followed by positioning the second forming tool in the cavity of the first intermediate structure;plastically deforming the base sidewall to form a second intermediate structure having a base sidewall and four inner sidewalls extending transversely from the base sidewall and defining a second cavity that opens in a second direction that is substantially opposite the first direction, wherein the inner sidewalls are spaced apart inwardly from the first sidewalls to define an annular space that opens in the first direction;filling the annular space with a highly porous insulating material;sealingly connecting the second sheet of material to the second intermediate structure around the peripheral edge to substantially close off the opening; andforming a vacuum in the annular space containing the insulation material. 2. The method of claim 1, wherein: the second sheet of material is spaced apart from the base sidewall of the second intermediate structure to form a central space that is connected to the annular space. 3. The method of claim 1, wherein: the second forming tool comprises compacted porous insulation material; andat least a portion of the second forming tool is disposed in the annular cavity while a vacuum is formed in the annular space. 4. The method of claim 1, further comprising; blowing air in the first direction on the first sheet of material to form a semi-circle shape. 5. The method of claim 1, further comprising; clamping at least one edge of the first sheet of material to at least one flange of the first forming tool, wherein the at least one flange is comprised of at least one sidewall of the first forming tool. 6. The method of claim 1, wherein: the first forming tool includes at least one vacuum channel. 7. The method of claim 6, wherein; the first forming tool is a male mold. 8. The method of claim 6, wherein; the first forming tool is a female mold. 9. A method of forming a vacuum insulated refrigerator cabinet, the method comprising: providing first and second sheets of material comprising at least a first layer of thermoplastic material that is at least partially permeable to oxygen, nitrogen and water vapor, and a second layer of material that is substantially impermeable to oxygen, nitrogen and water vapor;heating at least a portion of the first sheet of material to a temperature at which the first sheet of material can be plastically deformed;utilizing a first forming tool to deform the first sheet of material and form a first intermediate structure having a base sidewall and a plurality of first sidewalls extending transversely from the base sidewall to define a cavity having an opening that opens in a first direction and defines a peripheral edge extending around the opening;providing a second forming tool having sidewall portions defining a plurality of generally rectangular outwardly facing surfaces and a plurality of generally rectangular inwardly facing surfaces, and at least one end surface extending transversely between the inwardly and outwardly facing surfaces;disengaging the first intermediate structure from the first forming tool, followed by positioning the second forming tool in the cavity of the first intermediate structure;plastically deforming the base sidewall to form a second intermediate structure having a base sidewall and a plurality of inner sidewalls extending transversely from the base sidewall, wherein the plurality of inner sidewalls are spaced apart inwardly from the first sidewalls to define an annular space;filling the annular space with a highly porous insulating material;sealingly connecting the second sheet of material to the second intermediate structure around the peripheral edge to substantially close off the opening; andforming a vacuum in the annular space containing the insulation material. 10. The method of claim 9, wherein: the second sheet of material is spaced apart from the base sidewall of the second intermediate structure to form a central space that is connected to the annular space. 11. The method of claim 9, wherein: the second forming tool comprises the highly porous insulating material; andat least a portion of the second forming tool is disposed in the annular cavity while a vacuum is formed in the annular space. 12. The method of claim 9, further comprising; blowing air in the first direction on the first sheet of material to form a semi-circle shape. 13. The method of claim 9, further comprising; clamping at least one edge of the first sheet of material to at least one flange of the first forming tool, wherein the at least one flange is comprised of at least one sidewall of the first forming tool. 14. The method of claim 9, wherein; the first forming tool includes at least one vacuum channel. 15. The method of claim 14, wherein; the first forming tool is a male mold. 16. The method of claim 14, wherein; the first forming tool is a female mold. 17. A method of forming a vacuum insulated refrigerator cabinet, the method comprising: providing first and second sheets of material comprising at least a first layer of thermoplastic material, and a second layer of material that is substantially impermeable to oxygen, nitrogen and water vapor;heating at least a portion of the first sheet of material to a temperature at which the first sheet of material can be plastically deformed;utilizing a first forming tool to deform the first sheet of material and form a first intermediate structure having a base sidewall and a plurality of first sidewalls extending transversely from the base sidewall to define a cavity having an opening and defines a peripheral edge extending around the opening;providing a second forming tool having sidewall portions defining a plurality of outwardly facing surfaces and a plurality of inwardly facing surfaces, and at least one end surface extending transversely between the inwardly and outwardly facing surfaces;disengaging the first intermediate structure from the first forming tool, followed by positioning the second forming tool in the cavity of the first intermediate structure;plastically deforming the base sidewall to form a second intermediate structure having a base sidewall and a plurality of inner sidewalls extending transversely from the base sidewall, wherein the plurality of inner sidewalls are spaced apart inwardly from the first sidewalk to define an annular space;sealingly connecting the second sheet of material to the second intermediate structure around the peripheral edge to substantially close off the opening;filling the annular space with a highly porous insulating material; andforming a vacuum in the annular space. 18. The method of claim 17, wherein; the first forming tool includes at least one vacuum channel. 19. The method of claim 18, wherein; the first forming tool is a male mold. 20. The method of claim 18, wherein; the first forming tool is a female mold.
