A system for unloading loose materials from containers is fitted with a cartridge that defines a containing chamber for a tubular bag gathered in a resting position. The cartridge can be connected with an upper end to an outlet presented by a container to be emptied and the lower end presents a flange or cap that can be coupled to a connector arranged downstream. The system may also include a two-way drive mechanism for the flange or cap through a tube arranged between the container and the devices to be connected. The drive mechanism is designed to pass the bag, itself, extended in an operating position and to transfer the flange or cap outside the tube so as to allow the connection between the tubular bag and the devices to be connected.
