Abstract

A simple disposable absorbent article, which can be a pull-on garment, includes a chassis and an absorbent assembly. A belt is fastenable to the chassis, and both the belt and the chassis can be independently extensible or substantially inextensible. The belt can be fastened to the chassis at opposing ends, at least one of which being releasable and refastenable to induce a tension in the belt and a contractive force on the underlying chassis, thereby enhancing the fit of the garment at the wearer'"'"'s waist. The belt can further define a frangible region that can be broken to define opposing outer ends, at least one of which can be drawn and refastened to induce the contractive force on the underlying chassis.

Claims

1. A disposable absorbent article comprising:

a chassis defining a front waist region, a back waist region, a crotch region disposed between the waist regions, a waist opening, and a pair of leg openings;

an absorbent assembly attached to the chassis; and

a belt member attached to the chassis, the belt member extending across at least a portion of the chassis, the belt member including a frangible joint that is breakable to define a first and second free end, wherein the free ends are fastenable to at least one of each other and the chassis to impart a contractive force onto the chassis.

2. The disposable absorbent article as recited in claim 1, wherein the belt member is disposed in both the front and back waist regions of the garment.

3. The disposable absorbent article as recited in claim 1, wherein the belt member surrounds only a portion of the chassis before the frangible joint is broken.

4. The disposable absorbent article as recited in claim 3, wherein the frangible joint divides the belt member into first and second segments, each segment defining the first and second free ends, respectively.

5. The disposable absorbent article as recited in claim 1, wherein the belt further comprises an attachment zone disposed adjacent at least one of the free ends.

6. The disposable absorbent article as recited in claim 1, wherein at least one of the free ends is releasable and subsequently attachable to at least one of the chassis and a remaining segment of the belt member.

7. The disposable absorbent article as recited in claim 6, wherein the free ends are tied in a knot.

8. The disposable absorbent article as recited in claim 1, wherein the belt extends substantially along a longitudinal belt axis.

9. The disposable absorbent article as recited in claim 8, wherein at least a portion of the frangible joint extends in a direction parallel to the longitudinal belt axis.

10. The disposable absorbent article as recited in claim 9, wherein the frangible joint extends from opposing closed side interfaces on the chassis.

11. The disposable absorbent article as recited in claim 8, wherein at least a portion of the frangible joint extends in a direction perpendicular to the longitudinal belt axis.

12. The disposable absorbent article as recited in claim 8, wherein at least a portion of the frangible joint extends in a direction angled with respect to both 1) a direction perpendicular to the longitudinal belt axis 2) a direction parallel to the longitudinal belt axis.

13. The disposable absorbent article as recited in claim 1, wherein the belt member overlaps at least a portion of the front waist region.

14. The disposable absorbent article as recited in claim 13, wherein the belt member overlaps substantially all of the front waist region.

15. The disposable absorbent article as recited in claim 1, wherein the belt member overlaps at least a portion of the back waist region.

16. The disposable absorbent article as recited in claim 1, wherein the belt member overlaps substantially all of the front waist region.

17. The disposable absorbent article as recited in claim 1, wherein the belt member overlaps a closed side interface of the chassis.

18. The disposable absorbent article as recited in claim 1, wherein at least a portion of the belt member is extensible.

19. The disposable absorbent article as recited in claim 18, wherein the belt member is pre-tensioned.

20. The disposable absorbent article as recited in claim 18, wherein the belt member is non-pre-tensioned.

21. The disposable absorbent article as recited in claim 1, wherein at least a portion of the belt member is non-extensible.

22. The disposable absorbent article as recited in claim 1, wherein at least a portion of the chassis is extensible.

23. The disposable absorbent article as recited in claim 1, wherein at least a portion of the chassis is non-extensible.

24. The disposable absorbent article as recited in claim 1, further comprising a pull-on garment.

25. A method for securing a disposable absorbent article on a waist region of a wearer, the garment including a chassis defining a front waist region, a back waist region, and a crotch region disposed between the waist regions, the front and waist regions being closed to define a waist opening, the diaper further comprising a belt member attached to the chassis, the belt member including a frangible joint, wherein the method comprises the steps of:

A) pulling the absorbent article up to the waist region of the wearer such that the waist region is surrounded by the waist opening;

B) breaking the frangible joint to define first and second free ends;

C) after step (B), attaching at least one of the free ends to one of the chassis and a remaining portion of the belt member, thereby creating a contractive belt force to the chassis.

26. The method as recited in claim 25, wherein step (C) further comprising drawing the free ends together.

27. A disposable absorbent article comprising:

a chassis defining a front waist region, a back waist region, a crotch region disposed between the waist regions, a waist opening, and a pair of leg openings;

an absorbent assembly attached to the chassis; and

a belt member attached to the chassis at a first location, the belt member extending across at least portion of the chassis, the belt member defining opposing outer ends attached to the chassis at corresponding attachment zones, wherein at least one of the attachment zones is releasably attached to the chassis, wherein the releasable attachment zone can be released from the chassis and reattached to the chassis in a second location different than the first location, such that the belt applies a contractive belt force to the chassis.

28. The disposable absorbent article as recited in claim 27, further comprising a pull-on pant.
