Upright fluid container, esp. for urine has base surface of size so that center of gravity remains within base when container axis deviates from the vertical

摘要

The container (1) e.g. bottle has space for a weight and/or a ballast material. The circular base surface (3) of the container is dimensioned so that with an inclination of the longitudinal axis of the full container up to at least 15 deg , the vertical projection of the center of gravity (2) remains within the base surface. The container has a closure plate (4) at the top, connected to it via a hinge (8) so that it projects over the container edge. The cover is provided with a grip hole and has a seal.
