Abstract
The present invention comprises a vacuum insulation body comprising a vacuum-tight covering that surrounds an evacuated region, wherein a core material is arranged in the evacuated region, wherein the covering has an outer region and an inner region at least partially surrounded by the outer region, wherein the inner region and the outer region are formed by a common film bag and wherein the inner region is formed by inverting the film bag.

A method for making a refrigeration unit, which is a refrigerator, freezer, or a combined refrigerator-freezer unit, the method comprising:
- arranging a gas-tight film bag adjacent to an inner container of the refrigeration unit, the inner container comprising a wall bounding an inner space of the refrigeration unit to be formed, and the gas-tight film bag comprising a first region and a second region;
- contacting the first region of the gas-tight film bag with the inner container in a manner configured to map the first region of the gas-tight film bag to contours of the wall, thereby forming an inner region of the gas-tight film bag and inverting the gas-tight film bag so that the second region forms an outer region that at least partially surrounds the inner region mapped to the contours of the wall, thereby forming an inverted gas-tight film bag comprising a space between the inner region and the outer region;
- contacting the outer region of the inverted gas-tight film bag with an outer jacket of the refrigeration unit to be formed;
- filling the space between the inner region and the outer region with a core material to form a filled space;
- and
- evacuating and sealing the filled space to form a vacuum insulation body located between the wall of the inner container and the outer jacket.
