• Containers in various shapes for receiving bulk material are known. They are usually rigid or flexible (for example, so-called “big bags") and made of various materials, such as metal, for example steel or stainless steel, aluminum or plastic, for example polypropylene, HD or LD polyethylene or polyamide.
• An example of such containers are cylindrical or rectangular containers tapering downwards to a closable outlet followed by a short discharge tube for the bulk material, for example made of steel and usually having a volume of 0.5 to 5 m 3 .
