Abstract
Abstract Device for transporting pourable goods such as liquids or solids in bulk. Liquids are situated within a container made of a foldable sheet material and having upper and lower end regions. At its upper end region the container is carried by and suspended from a frame structure while at its lower end region the container is operatively connected with a guiding structure which guides the lower end of the container for movement in a predetermined direction which preferably extends in the direction of the travel of the device.
