A transport bag (15) for transporting and/or storing articles comprises a front wall (21b) and a back wall (21a) that are flexibly connected to one another via a bottom section (21c) so as to be movable back and forth between a first configuration in which the front wall and back wall form an upwardly open bag that can be filled from above, and a second configuration in which the front wall and back wall lie closely alongside one another and form a bag that is folded together, wherein the back wall (21a) is extended upward above and beyond the height of the front wall (21b) with a support section (15a) for fastening the transport bag (15) to a transport device (10.2). Easy filling and emptying of the transport bag (15) is achieved by providing an opening (16, 19, 20) that automatically brings the transport bag (15) into the first configuration and keeps the transport bag there, and allows a deliberate shift from the first configuration into the second configuration.
