System according to claim 7, wherein the filling pump of the filling apparatus is an pressure pump, the filling pump being adapted to fluidically couple to the flexible container and to a drug reservoir, the filling pump being adapted to force drug out of the drug reservoir and into the flexible container. 10. System according to claim 7, wherein the hollow support structure comprises a fluid-tight container compartment and the filling pump of the filling apparatus is a suction pump, the filling pump being fluidically coupled to the container compartment, the filling pump being adapted to suck air out of the container compartment, thus expanding the flexible container and sucking drug from a drug reservoir fluidically coupled to the flexible container into the flexible container. 11. System according to claim 7, wherein the filling apparatus comprises a pressure controller, the pressure controller being adapted to control or limit the operational pressure of the filling pump. 12. System according to claim 1, wherein the hollow support structure of the filling apparatus is, at least in part, integral with a housing of the infusion apparatus. 13. System according to claim 1, wherein the hollow support structure of the filling apparatus is, at least in part, integral with a removable packaging of the flexible container. 14. Container assembly, comprising: a flexible container comprising a rigid portion and a flexible portion that are coupled to one another and define a fluidic reservoir for containing a liquid drug, wherein the rigid portion of the flexible container is coupled to a sheet of an elastic foil and defines a filling volume therein for receiving the liquid drug and a fluidic connector for fluidically connecting and filling the filling volume of the flexible container with the liquid drug, the flexible container expanding upon being filled; anda hollow support structure defining a container compartment, the flexible container being, at least in part, arranged in the container compartment, the hollow support structure further comprising a first support element and a second support element, the first support element and the second support element being adapted to limit the expansion of the flexible container by contacting the partly rigid container body and the sheet of the elastic foil of the flexible container upon the filling volume of the flexible container being filled via the fluidic connector to a maximum filling volume, wherein a spacer structure is coupled to the first support element and the second support element, the spacer structure adjustably defining a displacement distance between the first support element and the second support element that adjustably defines the maximum filling volume of the flexible container. 15. A method of preventing overfilling a flexible container with a defined drug amount comprising utilizing the flexible container in a container assembly according to claim 14. 16. System according to claim 8, wherein the filling pump of the filling apparatus is an pressure pump, the filling pump being adapted to fluidically couple to the flexible container and to a drug reservoir, the filling pump being adapted to force drug out of the drug reservoir and into the flexible container. 17. System according to claim 8, wherein the hollow support structure comprises a fluid-tight container compartment and the filling pump of the filling apparatus is a suction pump, the filling pump being fluidically coupled to the container compartment, the filling pump being adapted to suck air out of the container compartment, thus expanding the flexible container and sucking drug from a drug reservoir fluidically coupled to the flexible container into the flexible container. 18. System according to claim 10, wherein the filling apparatus comprises a pressure controller, the pressure controller being adapted to control or limit the operational pressure of the filling pump. 19. System according to claim 11, wherein the hollow support structure of the filling apparatus is, at least in part, integral with a removable packaging of the flexible container. 20.
