The invention claimed is: 1. A device for packaging and dispensing several fluid products, comprising at least two sealed flexible bags placed in the same single rigid container, connected to at least one pump or valve, wherein each bag comprises means cooperating with at least one ring for fastening to the container and with the pump(s) or valve(s), and further comprising an air circuit between the outside and the volume between a wall of the rigid container and the bags, wherein the air circuit comprises a passage made in a rim of the ring, communicating with a space between the pump and a push-button, and comprising means for closing when the pump is not actuated. 2. The device as claimed in claim 1, wherein each bag comprises at least one flat surface for assembly with another bag. 3. The device as claimed in claim 2, comprising at least two bags combined with a single ring for fastening to the container and to the pump(s) or valve(s). 4. The device as claimed in claim 2, which comprises two bags formed as a single piece, in the form of a double bag comprising two compartments separated by a partition. 5. The device as claimed in claim 2, wherein the bags and the ring are formed as a single unitary piece, produced by molding using a suitable plastic. 6. The device as claimed in claim 2, wherein the bags are produced by injection-blow molding or extrusion-blow molding a material chosen from the group consisting of a polyethylene, a polypropylene, a polyamide, and an ethylene/vinyl alcohol (EVOH) copolymer. 7.
