Zusammenfassung: | A method for thermally insulating an evacuable container comprising an inner container, an outer container and a cavity, which is present between the inner container and the outer container, wherein a) a vacuum pump is used to reduce a pressure in the cavity and, once a first pressure value has been reached, the connection to the vacuum pump is broken, b) then a connection is established between astorage container for the thermally insulating, particulate material and a filling opening provided in the region of the cavity, c) the evacuable container is made to move, wherein the thermally insulating, particulate material flows into the cavity in accordance with a) and there is an increase in the pressure in the cavity as a result of the air introduced with the thermally insulating, particulate material, d) the filling operation is terminated at a second pressure value, by the connection between the cavity and the storage container being broken, e) step a) is repeated, wherein the capacity of the vacuum pump at |
