A container for liquid and free-flowing substances in which the outer surface of the bottom is made as a shape resembling a half-sphere the upper part of which passes in the walls of the container, and the lower part is truncated by the plane perpendicular to the axis of symmetry of the container in such a manner as to allow the shape of the bottom, which is formed by the truncation, that is a horizontal ground and continuation thereof, in particular the outer surface of the bottom, resembling the half-sphere, to have an ability of keeping the stable equilibrium of the container upon condition of stopping the action of the force, applied earlier, directed on overturning the container, which is provided by arranging the gravitational centre of the container maximum close to the centre of the bearing area which is formed by the above-mentioned truncation and on condition that the vertical line which passes through the gravitational centre of the container never falls outside the limits of the bearing area of the container. |
