Abstract
A high-safety container more particularly intended for dangerous products or installations. A tank includes an inner sidewall, a floor and a top which define a storage enclosure. A continuous leak-proof foundation basement includes a downwardly bulging cupola having a convex undersurface exposed throughout to external upwardly directed hydrostatic-like thrust. The tank floor is disposed above and laterally spaced from the upper concave face of the downwardly bulging cupola to define a lower ventilating gap therebetween. The pillars extend between the tank floor and the upper concave face to support the tank over the cupola. An outer wall integral with the cupola forms an upwardly projecting peripheral extension of the cupola. An annular space is defined between the outer wall and the inner side wall around the tank. A filler material disposed in the annular space contributes to the stability of the container with respect to lifting effects caused by hydrostatic thrust, even when the container is empty.
