Abstract
The present invention concerns a double-walled tank container, whereby the inner container is stored at the bottom inside the outer enclosure by a spacer consisting of several spacer pieces. The spacer provided, which is preferably placed near a front saddle ring, imparts transportation and storage stresses between the inner tank and the outer enclosure and consequently between the inner container and the frame of the tank container. The spacer can be laid out in such a way that it absorbs shocks and/or defines a hollow space. This hollow space can serve as a thermal insulation or for the installation of temperature equalization devices, mediums or a leak detector fluid.
