1. A flow reservoir for a paint spray gun, the paint spray gun having either a threaded connector or a screw-wedge connector for attaching a flow reservoir, the flow reservoir comprising: a container;a cover attachable to said container; andan attachment part integrally formed on said cover for fastening of the flow reservoir onto the paint spray gun, the attachment part including a tubular connector portion having a threaded connector operative to releasably attach to a threaded connector of a paint spray gun, and a screw-wedge connector operative to releasably attach to a mating portion of a screw wedge connector of a paint spray gun, said screw-wedge connector of the tubular connector portion including a wedge shaped groove being open at a front end thereof and closed by a ridge having a lateral contact surface at a rear end thereof for limiting the screw-in depth of the screw wedge connector of the paint spray gun. 2. The flow reservoir according to claim 1, wherein the wedge shaped groove is arranged in a shoulder which extends over an outer circumference of the screw wedge connector of the tubular connector portion. 3. The flow reservoir according to claim 1, wherein a shoulder with a contact surface is provided in an interior of the tubular connector portion. 4. The flow reservoir according to claim 1, wherein the cover is attachable to the container with a quick-connect locking thread, wherein said quick-connect locking thread is a four part thread. 5. The flow reservoir according to claim 4, wherein the quick-connect locking thread is an external thread with a major diameter between about 100 and 110 mm, and a minor diameter between about 90 and 105 mm. 6. The flow reservoir according to claim 1, wherein a wedge-shaped sealing ridge is formed on an inner side of the cover, said wedge shaped sealing ridge defining a wedge-shaped annular groove between an outer side of said wedge shaped sealing ridge and an inner side of the cover for receiving an upper edge of the container. 7. The flow reservoir according to claim 6, wherein the wedge-shaped sealing ridge has a sufficiently large height to catch paint in the cover when the cover is removed. 8. A flow reservoir for a paint spray gun, the paint spray gun having a threaded connector or a screw wedge connector for attaching a flow reservoir, said flow reservoir comprising: a container;a cover attachable to said container at a first end, and attachable to the paint spray gun at a second end; anda tubular extension integrally formed on said cover extending away from said first end at said second end, the extension having a first connector and a second connector, one of said first connector and said second connector including a threaded connector matable with a threaded connector of a paint spray gun, and the other of said first connector and said second connector including a screw wedge connector matable with a screw wedge connector of a paint spray gun, the screw wedge connector of the tubular extension including a wedge shaped groove being open at a front end thereof and closed by a ridge having a lateral contact surface at a rear end thereof for limiting the screw-in depth of the screw wedge connector of the paint spray gun, the flow reservoir thereby operable to connect to either a paint spray gun having a threaded connector or a paint spray gun having a screw wedge connector. 9. The flow reservoir according to claim 8, wherein the first or second connector including a threaded connector is positioned farther from said first end relative to the first or second connector including a screw wedge connector. 10. The flow reservoir according to claim 9, wherein a wedge-shaped sealing ridge is formed on an inner side of the cover, said wedge shaped sealing ridge defining a wedge-shaped annular groove between an outer side of said wedge shaped sealing ridge and an inner side of the cover for receiving an upper edge of the container. 11. The flow reservoir according to claim 10, wherein the wedge-shaped sealing ridge has a sufficiently large height to catch paint in the cover when the cover is removed. 12. The flow reservoir according to claim 8, wherein the wedge shaped groove is arranged in a shoulder extending along an outer circumference of the screw wedge connector of the tubular extension. 13. The flow reservoir according to claim 8, wherein the cover is attachable to the container with a quick-connect locking thread, wherein said quick-connect locking thread is a four part thread. 14. The flow reservoir according to claim 13, wherein the quick-connect locking thread is an external thread with a major diameter between about 100 and about 110 mm, and a minor diameter between about 90 and about 105 mm. 15. A flow reservoir for a paint spray gun, the paint spray gun having either a threaded connector or a screw wedge connector for attaching a flow reservoir, said flow reservoir comprising: a container;a cover attachable to said container at a first end, and attachable to the paint spray gun at a second end; anda tubular extension integrally formed on said cover extending away from said first end at said second end, the extension having a first connector and a second connector, wherein said second connector has a greater outer diameter than an outer diameter of said first connector and said second connector is positioned between said first connector and said first end, one of said first connector and said second connector including a threaded connector matable with a threaded connector of a paint spray gun, and the other of said first connector and said second connector including a screw wedge connector matable with a screw wedge connector of a paint spray gun, the screw wedge connector of the tubular extension including a wedge shaped groove being open at a front end thereof and closed by a ridge having a lateral contact surface at a rear end thereof for limiting the screw-in depth of the screw wedge connector of the paint spray gun, the flow reservoir thereby operable to connect to either a paint spray gun having a threaded connector or a paint spray gun having a screw wedge connector. 16. The flow reservoir according to claim 15, wherein the first or second connector including a threaded connector is positioned farther from said first end relative to the first or second connector including a screw wedge connector. 17. The flow reservoir according to claim 15, wherein the wedge shaped groove is arranged in a shoulder extending along an outer circumference of the screw wedge connector of the tubular extension. 18.
