Rectangular storage and transporting container

摘要

The container is made in two parts, like a beer keg or expansion tank, with rounded edges. It is of a bulging-shape on all sides. It has only one connecting thread or connecting point. The radii of the lateral areas (R2/R3) are in a ratio of greater than 1:10 to the radii (R5) of the rounded corners. The sidewalls have a radius which is more than ten times their length. For containers of capacity more than 400 litres, partition walls may be fitted. These are also bulged. The upper and lower parts may be produced by a deep drawing process.
