• the container is largely hollow, so preferably formed free of massive volume ranges; This saves weight and material and is suitable for injection molding in clamshell technology. Since the container is intended for receiving body fluids, there is the problem that when tilting the device, in particular in mobile operation or when fixing or loosening the container, the body fluid taken in its interior tends to flow following the gravity. This results in the liquid also entering and wetting or adhering to areas close to the engagement opening, which leads to unpleasant notions in transparent or at least not completely opaque materials, when the user manually grips the container or the container and in particular the area of the engagement opening consideration, in particular by third parties.
