Abstract
An absorbent article is disclosed. The absorbent article having a topsheet, a backsheet, and an absorbent core structure having one or more layers. The absorbent article has multiple zones.
Claims18
An absorbent article comprising:
- a transverse centerline,
- a topsheet,
- a backsheet, and
- an absorbent core structure disposed between the topsheet and the backsheet,
- wherein the absorbent core structure comprises a heterogeneous mass comprising a fibrous nonwoven web layer and a high internal phase emulsion (HIPE) foam layer,
- wherein fibers of the nonwoven web have been displaced with the HIPE foam layer wherein the displaced fibers of the nonwoven web and the HIPE foam occupy the same plane,
- wherein the topsheet and the heterogeneous mass are integrated to form an integrated absorbent structure comprising a first zone, a second zone, and a third zone,
- wherein at least a first boundary and a second boundary divide the first zone, the second zone, and the third zone,
- wherein the first zone has an area located along a portion of a longitudinal centerline,
- wherein the second zone has an area disposed between the first zone and a first side edge and the third zone has an area disposed between the first zone and a second side edge,
- wherein the first boundary and the second boundary converge and meet at a point at a boundary convergence area,
- wherein the point of the boundary convergence area is disposed on the longitudinal centerline such that the first boundary and the second boundary meet the longitudinal centerline at the point of the boundary convergence area,
- wherein the first zone has a first pattern, the second zone has a second pattern, and the third zone has a third pattern,
- wherein the first pattern and the second pattern are different and the first pattern and the third pattern are different,
- wherein the first zone exhibits a first CD Peak Force/Width and the second zone exhibits a second CD Peak Force/Width,
- wherein the first CD Peak Force/Width is greater than the second Peak Force/Width, as measured using a Three Point Bend method described herein.

- wherein at least a first boundary and a second boundary divide the first zone, the second zone, and the third zone,
- wherein the first boundary and the second boundary converge and meet at an intersection point at a boundary convergence area positioned between a lateral centerline and a back edge and disposed on a longitudinal centerline such that the first boundary and the second boundary intersect the longitudinal centerline at the intersection point of the boundary convergence area,
- wherein the first zone has an area located along the longitudinal centerline and extending from the boundary convergence area to a front edge,
- wherein the second zone has an area disposed between the first zone and a first side edge and the third zone has an area disposed between the first zone and a second side edge,
- wherein the fourth zone extends from the boundary convergence area to the back edge,
- wherein the first zone has a first pattern, the second zone has a second pattern, the third zone has a third pattern, and the fourth zone has a fourth pattern,
- wherein the first pattern is different from each of the second pattern, the third pattern, and the fourth pattern,
- wherein the first zone exhibits a first CD Peak Force/Width and the second zone exhibits a second CD Peak Force/Width, and
- wherein the first CD Peak Force/Width and the second Peak Force/Width are different, as measured using a Three Point Bend method described herein.
