1. A payload delivery system comprising, in its pre-launched configuration: a) a payload cup having an open fore end, a closed aft end, and a cylindrical side wall defining a cavity;b) a pleated cup coaxially aligned with the payload cup, having an open fore end, a closed aft end, and a pleated side
1. A payload delivery system comprising, in its pre-launched configuration: a) a payload cup having an open fore end, a closed aft end, and a cylindrical side wall defining a cavity;b) a pleated cup coaxially aligned with the payload cup, having an open fore end, a closed aft end, and a pleated side wall defining a cavity that terminates at an edge contiguous with the pleated cup open fore end, wherein the pleats of the pleated side wall extend substantially longitudinally; andwherein the payload cup is nested within the pleated cup, such that the payload cup aft end is adjacent and attached to the pleated cup aft end and the payload cup sidewall is in contact with the pleated cup sidewall. 2. A payload delivery system according to claim 1, further comprising: c) an obturating component adjacent the aft end of the pleated cup, comprising a pre-formed gas seal or an obturating medium. 3. A payload delivery system according to claim 1, further comprising: c) an obturating medium adjacent the aft end of the pleated cup. 4. A payload delivery system according to claim 1, further comprising: c) a pre-formed gas seal adjacent the aft end of the pleated cup and coaxially aligned with the payload cup and the pleated cup; andd) a connector that unites the pre-formed gas seal with the payload cup and the pleated cup. 5. A payload delivery system according to claim 1, wherein the pleated cup comprises paper, polymer, polymer coated paper, composite, laminate, or textile. 6. A payload delivery system according to claim 1, wherein the pleated side wall comprises knife plates, box pleats, accordion pleats, cartridge pleats, fluted pleats, Fortuny pleats, honeycomb pleats, organ pleats, pinch pleats, Plissé pleats, rolled pleats, Watteau pleats, or a combination thereof. 7. A payload delivery system according to claim 1, wherein the pleated side wall of the pleated cup is solid or perforated. 8. A payload delivery system according to claim 1, wherein the pleated side wall of the pleated cup extends greater than 50% the length of the cylindrical side wall of the payload cup. 9. A payload delivery system according to claim 1, wherein the aft end portion of the payload cup is recessed in an annular fashion from the fore end portion, wherein the aft end portion has a smaller diameter than the fore end portion, and the pleated side wall of the pleated cup extends the length of the recessed aft end portion of the payload cup. 10. A payload delivery system according to claim 1, wherein the closed aft end of the payload cup is crimped. 11. A payload delivery system according to claim 1, wherein the payload cup and the pleated cup are attached with a connector. 12. A payload delivery system according to claim 11, wherein the connector is selected from a rivet, a screw, a staple, a pin, a bolt, a brad, an anchor, an adhesive, a tack, or a nail. 13. A payload delivery system according to claim 11, wherein the connector comprises an integral pre-formed gas seal. 14. A cartridge comprising a payload delivery system according to claim 1, wherein the cartridge is an ammunition cartridge, a flare cartridge, a smoke flare cartridge, a signaling device cartridge, a chemical cartridge, a distraction device cartridge, a pyrotechnic launching device cartridge, a marking cartridge, a grenade launcher cartridge, an incendiary cartridge, an explosive cartridge, a tracer cartridge, an armor-piercing cartridge, or a non-lethal cartridge. 15. A cartridge comprising a payload delivery system according to claim 1, further comprising at least one of a frangible projectile, a non-frangible projectile, a lead projectile, a non-lead metal projectile, a steel projectile, a rubber projectile, a bean bag projectile, a tear gas-containing projectile, an oleoresin capsicum-containing projectile, a liquid-containing projectile, a powder-containing projectile, a gel-containing projectile, a marking projectile, a tracer projectile, a penetrator projectile, a flechette projectile, an armor-piercing projectile, an explosive projectile, an incendiary projectile, a flare projectile, or any combination thereof. 16. A cartridge comprising a payload delivery system according to claim 1 and at least one projectile selected from birdshot, buckshot, and slug projectiles. 17. A cartridge comprising a payload delivery system according to claim 1, further comprising at least one additional wad. 18. A cartridge comprising: a) a cartridge case having a fore end and an aft end and, comprising a primer situated at the aft end;b) a propellant adjacent the primer;c) an obturating component adjacent the propellant;d) a payload delivery system according to claim 1 adjacent the obturating component, ande) a payload at least partially contained within the cavity of the payload cup. 19. A cartridge according to claim 18, wherein obturating component comprises a pre-formed gas seal or an obturating medium.
