Abstract

An absorbent article having a topsheet having a first portion and a second portion. The topsheet has a longitudinal centerline and a transverse centerline. The topsheet has an area. The second portion can differ in structure from the first portion. The second portion can have a structurally modified zone. The structurally modified zone has a periphery, a length, and a long axis. The length is the maximum straight-line dimension between two points on the periphery. The long axis extends between two points on the periphery separated by the length. The long axis of the structurally modified zone can be asymmetric to the longitudinal centerline. The structurally modified zone can make up more than about 5% of the area of the topsheet. The topsheet can have a lotion zone, the long axis of which is asymmetric to the longitudinal centerline and the transverse centerline.

Claims (34)

1. An absorbent article comprising a topsheet, a backsheet, and an absorbent core disposed between said topsheet and said backsheet, said topsheet comprising a first portion and a second portion, said topsheet having a longitudinal centerline that is coincident with a longitudinal axis of said absorbent article and a transverse centerline, said topsheet having an area;

wherein said first portion comprises a first structurally modified zone comprising a first plurality of apertures;

wherein said second portion comprises a second structurally modified zone comprising a second plurality of apertures that are different from said first plurality of apertures, wherein said second structurally modified zone has a periphery, a length, and a long axis, said length being a maximum straight-line dimension between two points on said periphery, said long axis extending between two points on said periphery separated by said length;

wherein said periphery is not symmetric about an axis parallel to said longitudinal centerline;

wherein said long axis of said second structurally modified zone is asymmetric to said longitudinal centerline;

wherein said first plurality of apertures are substantially flat in the plane of said topsheet and wherein at least some of said second plurality of apertures comprises an aperture sidewall that protrudes outwardly from said topsheet in a direction away from said absorbent core; and

wherein said second structurally modified zone comprises more than about 5% of said area of said topsheet.

2. An absorbent article comprising a topsheet, a backsheet, and an absorbent core disposed between said topsheet and said backsheet, said topsheet comprising:

a first portion comprising a first plurality of apertures, at least some of which comprising an aperture sidewall that protrudes outwardly from a MD-CD plane of said topsheet in a direction away from said absorbent core;

a second portion comprising a second plurality of apertures, at least some which being substantially flat wherein an aperture sidewall does not extend substantially beyond said MD-CD plane of said topsheet; and

an embossed channel disposed between said first portion and said second portion,

wherein said topsheet comprises a nonwoven.

3. The absorbent article of claim 2 , wherein said topsheet is a laminate comprising a film layer and a nonwoven layer.

4. The absorbent article of claim 2 , wherein said topsheet is a laminate comprising a first nonwoven layer and a second nonwoven layer.

5. The absorbent article of claim 2 , wherein said absorbent article further comprises one or more colors visible through said topsheet, said one or more colors includes a first color associated with said embossed channel and a second color associated with said second portion.

6. The absorbent article of claim 5 , wherein said one or more colors includes a third color associated with said first portion.

7. An absorbent article comprising a topsheet, a backsheet, and an absorbent core disposed between said topsheet and said backsheet, said topsheet comprising:

a first portion comprising a first plurality of apertures, at least some of which comprising an aperture sidewall that protrudes outwardly from a MD-CD plane of said topsheet in a direction away from said absorbent core;

a second portion comprising a second plurality of apertures, at least some which being substantially flat wherein an aperture sidewall does not extend substantially beyond said MD-CD plane of said topsheet; and

one or more colors visible through said topsheet, wherein said one or more colors includes a first color associated with said first portion and a second color associated with said second portion,

wherein said topsheet comprises a nonwoven.

8. The absorbent article of claim 7 , wherein said absorbent article further comprises an embossed channel disposed between said first portion and said second portion.

9. The absorbent article of claim 7 , wherein said topsheet is a laminate comprising a film layer and a nonwoven layer.

10. The absorbent article of claim 7 , wherein said topsheet is a laminate comprising a first nonwoven layer and a second nonwoven layer.

11. An absorbent article comprising a topsheet, a backsheet, and an absorbent core disposed between said topsheet and said backsheet, said topsheet comprising:

a first portion comprising a first plurality of apertures, at least some of which comprising an aperture sidewall that protrudes outwardly from a MD-CD plane of said topsheet in a direction away from said absorbent core;

a second portion comprising a second plurality of apertures, at least some which being substantially flat wherein an aperture sidewall does not extend substantially beyond said MD-CD plane of said topsheet;

an embossed channel disposed between said first portion and said second portion; and

a plurality of microapertures having an aperture area in said MD-CD plane of less than 0.25 mm 2 .

12. An absorbent article comprising a topsheet, a backsheet, and an absorbent core disposed between said topsheet and said backsheet, said topsheet comprising:

a first portion comprising a first plurality of apertures, at least some of which comprising an aperture sidewall that protrudes outwardly from a MD-CD plane of said topsheet in a direction away from said absorbent core;

a second portion comprising a second plurality of apertures, at least some which being substantially flat wherein an aperture sidewall does not extend substantially beyond said MD-CD plane of said topsheet;

a plurality of microapertures having an aperture area in said MD-CD plane of less than 0.25 mm 2 ; and

one or more colors visible through said topsheet, wherein said one or more colors includes a first color associated with said first portion and a second color associated with said second portion.
