Abstract
The invention concerns a large-capacity stackable drum with a substantially cylindrical sidewall and top and bottom ends. To improve the stackability in particular the long-term stackability an internal hydrostatic pressure which supports the side wall is initially produced, when stacking several drums one on top of the other, in the gas space above the content and in the contents, of the drums stacked underneath, by virtue of the elastic flexibility of the top and/or the bottom of the drum, until a reduced stacking load acting through the top rim or grip ring of the drum into the drumwall is produced or support provided through the bottom rim or grip ring.
