Abstract

An absorbent article includes an outercover, a bodyside liner, and an absorbent assembly positioned between the outercover and the bodyside liner. The absorbent assembly includes an absorbent core at least partially enveloped by at least one nonwoven core wrap. The absorbent assembly has a rear extension region length of at least 30 mm. The absorbent core may include at least 60 percent superabsorbent and the bodyside liner may include apertures.

Claims

1. An absorbent article comprising,

a. an outercover,

b. a bodyside liner, and

c. an absorbent assembly positioned between the outercover and the bodyside liner, the absorbent assembly comprising, a nonwoven core wrap at least partially enveloping an absorbent core, the absorbent assembly having a rear extension region length of at least 30 mm.

2. The absorbent article of claim 1 wherein the absorbent assembly has a core wrap region length that is less than 90 percent of an absorbent assembly length.

3. The absorbent article of claim 1 wherein the absorbent assembly has a front extension region length and the ratio of the rear extension region length to the front extension region length is at least 1.5 to 1.

4. The absorbent article of claim 1 wherein the absorbent assembly has a front extension region length and the ratio of the rear extension region length to the front extension region length is at least 2 to 1.

5. The absorbent article of claim 1 wherein the nonwoven core wrap comprises thermoplastic fibers.

6. The absorbent article of claim 5 wherein the nonwoven core wrap is folded around the absorbent core and overlaps onto itself.

7. The absorbent article of claim 6 wherein the absorbent assembly has a core wrap region and the nonwoven core wrap is at least partially bonded to itself in the core wrap region.

8. The absorbent article of claim 6 wherein the nonwoven core wrap is at least partially bonded to itself in a front extension region and a rear extension region.

9. The absorbent article of claim 8 wherein the absorbent core comprises at least 60 percent superabsorbent by weight.

10. The absorbent article of claim 1 wherein the absorbent core has a liner facing surface and an outercover facing surface, the nonwoven core wrap overlies the liner facing surface and partially overlies the outercover facing surface, the nonwoven core wrap being adhesively joined with the outercover in a front extension region and the rear extension region.

11. An absorbent article comprising,

a. an outercover,

b. a bodyside liner, and

c. an absorbent assembly positioned between the outercover and the bodyside liner, the absorbent assembly comprising, an absorbent core positioned between a first nonwoven core wrap and a second nonwoven core wrap, the absorbent assembly having a rear extension region length of at least 30 mm.

12. The absorbent article of claim 11 wherein the absorbent core comprises at least 60 percent superabsorbent material by weight.

13. The absorbent article of claim 12 wherein the bodyside liner comprises a plurality of apertures.

14. The absorbent article of claim 12 wherein the first nonwoven core wrap and the second nonwoven core wrap comprise thermoplastic fibers.

15. The absorbent article of claim 14 wherein the first and the second nonwoven core wraps are at least partially bonded together in at least a front extension region and a rear extension region.

16. The absorbent article of claim 15 wherein the front extension region has a front extension region length and the rear extension region has a rear extension region length and the ratio of the rear extension region length to the front extension region length is at least 2 to 1.

17. The absorbent article of claim 15 wherein the first nonwoven core wrap is hydrophilic and the second nonwoven core wrap is hydrophobic.

18. The absorbent article of claim 11 wherein the absorbent article has a front extension region length of at least 10 mm.

19. An absorbent article comprising,

a. an outercover,

b. a bodyside liner, and

c. an absorbent assembly positioned between the outercover and the bodyside liner, the absorbent assembly comprising an absorbent core positioned between a first thermoplastic hydrophilic nonwoven core wrap and a second thermoplastic hydrophobic nonwoven core wrap, the absorbent core comprising at least 60 percent superabsorbent and the absorbent assembly having a rear extension region length of at least 30 mm.

20. The absorbent article of claim 19 wherein the absorbent core has a liner facing surface, an outercover facing surface and lateral side edges, the first nonwoven core wrap overlies the liner facing surface, the lateral side edges and least a portion of the outercover facing surface, the second nonwoven core wrap at least partially overlies the outercover facing surface, the first nonwoven core wrap being at least partially adhesively bonded to the second nonwoven core wrap in a front extension region and a rear extension region.
