Abstract

A disposable absorbent article comprising an absorbent core having a garment surface and an opposed body surface, which surfaces meet along at least one longitudinal edge and at least one end edge; 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; and a waistcap/waistband disposed adjacent to at least one projection associated with the absorbent core, wherein the waistcap/waistband is capable of absorbing moisture and subsequently deforming to fill at least a portion of space between the article and a portion of the wearer's body.

Claims (24)

1. A disposable absorbent article comprising:

an absorbent core having a garment surface and an opposed body surface, wherein the surfaces meet along at least one longitudinal edge and at least one end edge; wherein the at least one end edge is associated with multiple projections of the absorbent core;

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; and

a waistcap and/or waistband disposed adjacent to the multiple projections of the absorbent core,

wherein the waistcap and/or waistband comprises an absorbent core material and is capable of absorbing moisture and subsequently deforming to fill at least a portion of space between the article and a portion of the wearer's body,

wherein when one or more of the multiple projections are wetted by fluid and subsequently swell, the wetted projections elevate portions of the waistcap and/or waistband to form one or more channels between the waistcap and/or waistband and the projections so that fluid flows within the channels and away from the wearer's body.

2. The disposable absorbent article of claim 1 , wherein at least a portion of the waistcap and/or waistband is positioned adjacent to a front edge of the article.

3. The disposable absorbent article of claim 1 , wherein at least a portion of the waistcap and/or waistband is positioned adjacent to a back edge of the article.

4. The disposable absorbent article of claim 1 , wherein the waistcap and/or waistband comprises a front waistcap and/or waistband portion positioned adjacent to a front edge of the article, and further comprises a back waistcap and/or waistband portion positioned adjacent to an opposing back edge of the article.

5. The disposable absorbent article of claim 1 , wherein the waistcap and/or waistband is operable to be oriented adjacent to a wearer's waist.

6. The disposable absorbent article of claim 1 , wherein at least a portion of the waistcap and/or waistband is operable to mount to both a left side cuff and a right side cuff.

7. The disposable absorbent article of claim 1 , wherein the absorbent core comprises an absorbent particulate polymer material and which is substantially cellulose free.

8. The disposable absorbent article of claim 1 , further comprising a nonwoven backsheet disposed between the absorbent core and the liquid impermeable backsheet.

9. The disposable absorbent article of claim 1 , further comprising a pair of side panels.

10. The disposable absorbent article of claim 9 , 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.

11. The disposable absorbent article of claim 9 , comprising a pair of side panels that are joined to each other to form a pant.

12. A disposable absorbent article comprising:

an absorbent core having a garment surface and an opposed body surface, wherein the surfaces meet along at least one longitudinal edge and at least one end edge, wherein the absorbent core comprises an absorbent particulate polymer material and which is substantially cellulose free; wherein the at least one end edge is associated with multiple projections of the absorbent core;

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; and

a waistcap and/or waistband disposed adjacent to the multiple projections of the absorbent core,

wherein when one or more of the multiple projections are wetted and subsequently deform, the wetted projections elevate portions of the waistcap and/or waistband to form one or more channels between the waistcap and/or waistband and the multiple projections so that fluid flows within the channels and away from the wearer's body, and

wherein the waistcap and/or waistband comprises an absorbent core material and is operable to form a continuous gasket around the portion of the wearer's body.
