<p>A container includes at least one wall with inner and outer skins of metal defining a sealed region therebetween. A sealing cuff extends between apertures in the two skins to define a passage through the wall. The sealing cuff is made of a tube of corrugated metal, a first washer at one end of the tube welded around the aperture in one of the skins and a second washer at the other end of the tube welded around the aperture in the other of the skins. The first washer extends transversely inwards of the tube to assist in construction of the container. The region between the inner and outer skins may be evacuated of gases and contain thermally insulating material. Containers having external walls of this type can be used as battery boxes for batteries comprising one or more high temperature cells.</p> |
