CLAIMS

What is claimed is:

1. A disposable absorbent article for wearing about the lower torso of a wearer, the disposable absorbent article comprising:

a first waist region having a first waist edge, a second waist region having a second waist edge, a crotch region disposed between the first and second waist regions; and a first longitudinal edge and a second longitudinal edge; and a longitudinal centerline; a chassis comprising a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and

a back ear joined to the chassis in the second waist region;

wherein the first longitudinal edge, second longitudinal edge, first waist edge and second waist edge define a chassis periphery and the chassis periphery is characterized by a varying width, Wv, the varying width Wv comprising a first maximum width, Wi, in the first waist region, a minimum width, Wmm, in the crotch region, and a second maximum width, W2, in the second waist region, wherein Wi is greater than W2.

2. The disposable absorbent article of Claim 1 wherein the back ear is characterized by a highly extensible ear.

3. The disposable absorbent article of Claims 1 or 2 wherein the backsheet is characterized by a material periphery, the material periphery being coterminous with the chassis periphery.

4. The disposable absorbent article of any of the preceding claims wherein the back ear is joined to a garment-facing side of the backsheet.

5. The disposable absorbent article of Claim 4 further characterized by a fastening system joined to the back ear, the fastening system having an inboard fastening edge wherein the lateral distance, DLE_FE, between the inboard fastening edge and one of the first longitudinal edge or the second longitudinal edge along the length of the inboard fastening edge is 0 mm or greater.

6. The disposable absorbent article of Claims 1-3 wherein the back ear is joined to a body-facing side of a layer of the chassis.

7. The disposable absorbent article of any of the preceding claims wherein the first edge and/or the second edge comprises an edge width, WE, and the edge width, WE, is less than the first maximum width, Wi.

8. The disposable absorbent article of any of the preceding claims further characterized by a first maximum width to minimum width ratio, Wi:Wmin, of from about 1.4 and about 2.7.

9. The disposable absorbent article of any of the preceding claims further characterized in that the first waist region comprises a first maximum width zone and wherein the first longitudinal edge and the second longitudinal edge are continually sloping outside of the first maximum width zone.

10. The disposable absorbent article of any of the preceding claims wherein the first waist region is characterized by a landing zone disposed a lateral distance of about 2 mm or less from the longitudinal centerline.

11. The disposable absorbent article of any of the preceding claims further characterized by a leg gasketing system comprising an outer cuff having an outer cuff edge, an inner cuff, and an elasticized region.

12. The disposable absorbent article of Claim 11 wherein the article is further characterized by two leg gasketing systems disposed along opposite longitudinal edges and a maximum cuff width, Wcuff, the maximum cuff width, Wcuff, being the maximum lateral distance between the outer cuff edges of each leg gasketing system, and wherein the Wcuff is at least about 10 mm greater than the minimum width, Wmin.

13. The disposable absorbent article of any of the preceding claims wherein the backsheet is characterized by a polymeric film layer having a polymeric maximum lateral width, Wpoiy, wherein the polymeric maximum lateral width, Wpoiy, is less than the minimum width, Wmin.

14. The disposable absorbent article of any of Claims 1-12 wherein the backsheet is characterized by a polymeric film layer having a polymeric maximum lateral width, Wpoiy, wherein the polymeric maximum lateral width, Wpoiy, is less than the first maximum width, Wi, and the polymeric maximum lateral width, Wpoiy, is greater than the minimum width, Wmm.

15. The disposable absorbent article of any of the preceding claims further characterized by a waist gasketing element joined to the chassis in one of the first or second waist regions, wherein the waist gasketing system comprises an elasticized region.
