1. A disposable absorbent article comprising: an absorbent core having a garment surface and an opposed body surface, which surfaces meet along a pair of longitudinal edges and a pair of end edges;a liquid permeable topsheet positioned adjacent the body surface of the absorbent core and having a pair of opposed longitudinal edges;a liquid impermeable backsheet positioned adjacent the garment surface of the absorbent core; anda pair of elastically contractible cuffs, each of which is constructed of a continuous cuff material and has a standing cuff portion which comprises one or more elastic members,wherein each elastically contractible cuff is secured about one of said longitudinal edges of the topsheet by an assembly bond, with the standing cuff portion having a free edge and being laterally offset away from the longitudinal edge of the absorbent core; wherein the assembly bond is located outboard of the absorbent core and inboard of all of the elastic members of the standing cuff portion; wherein each cuff includes one or more cuff folds, a cuff fold bond, and a cuff end bond. 2. The disposable absorbent article of claim 1, wherein the elastically contractible cuff is attached to the topsheet. 3. The disposable absorbent article of claim 2, wherein the elastically contractible cuff is mechanically bonded to the topsheet or glued to the backsheet. 4. The disposable absorbent article of claim 1, wherein the elastically contractible cuff is attached to the backsheet. 5. The disposable absorbent article of claim 1, wherein the standing cuff portion comprises at least two layers of the continuous cuff material. 6. The disposable absorbent article of claim 5, wherein two or more of the elastic members are disposed between the at least two layers of the continuous cuff material, wherein one or more of the elastic members are fixed to the continuous cuff material by intermittent adhesive zones, wherein the adhesive zones comprise at least two discrete sections along the length of the elastic member. 7. The disposable absorbent article of claim 1, wherein the standing cuff portion comprises at least three layers of the continuous cuff material. 8. The disposable absorbent article of claim 1, wherein the continuous cuff material comprises a proximate end region and a distal end region, and both of the end regions are bonded together with the assembly bond. 9. The disposable absorbent article of claim 1, wherein the absorbent core comprises an absorbent particulate polymer material and which is substantially cellulose free. 10. The disposable absorbent article of claim 1, further comprising a pair of waistbands located, along opposing end edges of the topsheet. 11. The disposable absorbent article of claim 10 wherein the pair of elastically contractible cuffs are connected with the pair of waistbands to form a continuous gasket around the periphery of the absorbent core. 12. The disposable absorbent article of claim 1, further comprising a pair of side panels. 13. The disposable absorbent article of claim 12 wherein the absorbent article is a diaper and the pair of side panels comprise a re-closable fastening system for securing the diaper to a wearer. 14. The disposable absorbent article of claim 12 wherein the absorbent article is a pant-type diaper and the pair of side panels are joined to each other to form a pant. 15. The disposable absorbent article of claim 1, wherein the standing cuff portion is folded so that the distal edge of the standing cuff portion is pointing outboard of the absorbent article. 16. The disposable absorbent article of claim 1, wherein at least a portion of the contractible cuff is constructed of a single layer of a continuous cuff material. 17. A disposable absorbent article comprising: an absorbent core having a garment surface and an opposed body surface, which surfaces meet along a pair of longitudinal edges and a pair of end edges, wherein the absorbent core comprises an absorbent particulate polymer material and which is substantially cellulose free;a liquid permeable topsheet positioned adjacent the body surface of the absorbent core and having a pair of opposed longitudinal edges and a pair of opposed end edges;a liquid impermeable backsheet positioned adjacent the garment surface of the absorbent core;a pair of elastically contractible cuffs, each of which is constructed of a continuous cuff material and has a standing cuff portion which comprises from two to four elastic members, wherein each elastically contractible cuff is secured about one of said longitudinal edges of the topsheet by an assembly bond, with the standing cuff portion having a free edge and being laterally offset away from the longitudinal edge of the absorbent core; wherein the assembly bond is located outboard of the absorbent core and inboard of all of the elastic members of the standing cuff portion; wherein each cuff includes one or more cuff folds, a cuff fold bond, and a cuff end bond; anda pair of unitary waistbands connected to the pair of elastically contractible cuffs to form a continuous gasket around the periphery of the absorbent core area, wherein the elastically contractible cuff is mechanically bonded to the topsheet and glued to the backsheet.
