A cartridge is provided in the form of a sheet of material having swingable flaps extending from opposing side regions. A folded bag, which is to be filled with fluid, is positioned on the sheet and attached to the flaps, and the flaps are folded thereover in the initial position. In use, the cartridge is placed in a casing and, upon filling, the bag expands in a controlled manner and pushes back the flaps.
