Abstract

An absorbent article can have a topsheet layer, a liquid impermeable layer, and an absorbent core positioned between the topsheet layer and the liquid impermeable layer. The absorbent article can further include an exudate management layer in fluid communication with the topsheet layer. In various embodiments, the exudate management layer can be positioned on a body facing surface of the topsheet layer. In various embodiments, the exudate management layer can be positioned between the topsheet layer and the absorbent core. The exudate management layer has a first component which defines an opening for direct passage of body exudates into the absorbent core. The exudate management layer has a second component which at least partially overlaps the first component of the exudate management layer and further extends in the longitudinal direction of the absorbent article in a direction towards the posterior region of the absorbent article.

Claims (23)

1. An absorbent article comprising:

a) a longitudinal direction and a transverse direction;

b) a longitudinal centerline and a transverse centerline;

c) an anterior region, a posterior region, and a central region positioned between the anterior region and the posterior region;

d) an anterior region transverse direction end edge, a posterior region transverse direction end edge, and a pair of longitudinal direction side edges extending between and connecting the anterior region transverse direction end edge and the posterior region transverse direction end edge;

e) a topsheet layer defining a body facing surface of the absorbent article, a liquid impermeable layer defining a garment facing surface of the absorbent article, and an absorbent core positioned between the topsheet layer and the liquid impermeable layer; and

f) a liquid permeable exudate management layer in fluid communication with the topsheet layer and disposed between the topsheet layer and the absorbent core, the exudate management layer comprising a first component comprising an outer peripheral edge and an opening in the exudate management layer, the opening located inward from the outer peripheral edge and having a perimeter partially defined by an inner edge of the first component, and a second component connected to the first component via a primary fold, the primary fold defining at least a portion of the perimeter of the opening.

2. The absorbent article of claim 1 wherein the second component extends from the primary fold in the longitudinal direction towards the posterior region of the absorbent article.

3. The absorbent article of claim 1 wherein the second component extends from the primary fold in the longitudinal direction towards the anterior region of the absorbent article.

4. The absorbent article of claim 1 wherein the exudate management layer is positioned on the body facing surface of the topsheet layer.

5. The absorbent article of claim 1 wherein the exudate management layer is positioned between the topsheet layer and the absorbent core.

6. The absorbent article of claim 1 further comprising an acquisition layer.

7. The absorbent article of claim 1 wherein the second component comprises a secondary fold.

8. The absorbent article of claim 1 further comprising a third component connected to the first component of the exudate management layer via a third component primary fold.

9. The absorbent article of claim 8 wherein the third component extends from the third component primary fold in the longitudinal direction towards the anterior region of the absorbent article.

10. The absorbent article of claim 1 wherein the second component at least partially overlaps the first component.

11. The absorbent article of claim 1 wherein the second component at least partially underlaps the first component.

12. The absorbent article of claim 1 wherein the absorbent article further comprises an opposing pair of containment flaps extending in the longitudinal direction of the absorbent article.

13. The absorbent article of claim 1 wherein the topsheet layer is a fluid entangled laminate web comprising a support layer comprising a plurality of fibers and opposed first and second surfaces; a projection layer comprising a plurality of fibers and opposed inner and outer surfaces, the second surface of the support layer in contact with the inner surface of the projection layer, fibers of at least one of the support layer and the projection layer being fluid-entangled fibers of the other of the support layer and the projection layer; a plurality of hollow projections formed form a first plurality of the plurality of fibers in the projection layer, the plurality of hollow projections extending from the outer surface of the projection layer in a direction away from the support layer; and a land area, wherein the plurality of hollow projections are surrounded by the land area.

14. The absorbent article of claim 1 wherein the absorbent core comprises a body facing surface and projections extending away from the body facing surface of the absorbent core.

15. The absorbent article of claim 1 wherein the second component comprises at least one opening.

16. The absorbent article of claim 1 wherein the opening crosses over the transverse centerline of the absorbent article.

17. The absorbent article of claim 1 wherein the opening is positioned between the transverse centerline of the absorbent article and an anterior region transverse direction end edge of the absorbent article.
