ABSTRACT AN insulating container, in particular an insulating flask The invention relates to an insulating container (1), in particular an insulating flask, with a vacuum glass in- sert (2) and a hollow cylindrical housing (3) surrounding the latter. Housing (3) consists of an upper part (4) and a lower part (5) which are screwed together, the upper part (4) having an outer screw thread (6) and the lower part (5), in the form of a base with a raised-up edge, having an inner screw thread (8). To cope with different lengths of vacuum glass inserts (2) within a tolerance range the screw thread (6) is made sufficiently long to enable all such inserts to be held firmly between a shoulder (9) in the upper part (4) and a thrust or support piece 12 in the lower part (5). The edge of the housing lower part (5) is provided with a one-piece extension which overlaps the housing upper part (4) beyond the screw thread (6) to form a cover ring (28) for any unused area of the screw thread (6).
