Flexible absorbent article with a lobed absorbent layer

1. An absorbent article characterized by comprising:

a. a longitudinal direction, a transverse direction, and a depth direction;

b. a longitudinal axis and a transverse axis wherein the absorbent article is asymmetrical about the transverse axis;

c. a chassis comprising:

i. a first transverse direction end edge and a second transverse direction end edge;

ii. a topsheet layer comprising a first longitudinal direction peripheral edge and a second longitudinal direction peripheral edge;

iii. a backsheet layer comprising a first longitudinal direction peripheral edge and a second longitudinal direction peripheral edge;

iv. an absorbent system positioned between the topsheet layer and the backsheet layer, the absorbent system comprising a garment facing surface, a wearer facing surface, a first longitudinal direction peripheral region and a second longitudinal direction peripheral region, and at least two absorbent layers, wherein at least one of the absorbent layers of the absorbent system is a lobed absorbent layer comprising a first lobe and a second lobe wherein the first and second lobe define a longitudinally extending void space in the lobed absorbent layer, and wherein the lobed absorbent layer further comprises a transversely extending void space;

v. a first longitudinal direction bond region wherein the first longitudinal direction peripheral edge of the topsheet layer is bonded to the first longitudinal direction peripheral edge of the backsheet layer; and

vi. a second longitudinal direction bond region wherein the second longitudinal direction peripheral edge of the topsheet layer is bonded to the second longitudinal direction peripheral edge of the backsheet layer;

vii. at least one flexure feature wherein the at least one flexure feature comprises at least one flexure element extending in a direction generally parallel to the longitudinal axis and wherein the at least one flexure element is positioned within the void space; and

viii. a secondary flexure feature extending in a direction generally parallel to the transverse axis and positioned within the transversely extending void space; and

d. a first non-integral wing and a second non-integral wing, each of the first and second non-integral wings bonded to the backsheet layer.

2. The absorbent article of claim 1 further comprising a first side cover bonded to the chassis in the region of the first longitudinal direction bond region and a second side cover bonded to the chassis in the region of the second longitudinal direction bond region.

3. The absorbent article of claim 2 wherein each of the first side cover and the second side cover is bonded to an exterior surface of the backsheet layer.

4. The absorbent article of claim 2 wherein each of the first side cover and the second side cover extend between the first transverse direction end edge and the second transverse direction end edge of the chassis.

5. The absorbent article of claim 2 wherein each of the first side cover and the second side cover have at least one concave region and at least one convex region.

6. The absorbent article of claim 1 wherein the first non-integral wing and the second non-integral wing are separate components from each other.

7. The absorbent article of claim 1 wherein the first non-integral wing and the second non-integral wing are integral with a bridge which is bonded to the backsheet layer.

8. The absorbent article of claim 1 wherein at least one of the first transverse direction end edge and the second transverse direction end edge has at least one concave region.

9. The absorbent article of claim 1 wherein the at least one flexure feature comprises a second flexure element, the second flexure element spaced in the transverse direction outward from the first flexure element and positioned at an angle relative to the longitudinal axis.

10. The absorbent article of claim 9 wherein the second flexure element is aligned with an interior side edge of at least one of the lobes of the lobed absorbent layer.

11. The absorbent article of claim 1 further comprising a garment attachment on an exterior surface of the backsheet layer wherein the backsheet layer is substantially free of the garment attachment in an area of the backsheet layer positioned below the flexure feature in the depth direction of the absorbent article.

12. The absorbent article of claim 1 wherein the absorbent system further comprises at least one additional layer selected from a surge layer, a fluid intake layer, a transfer delay layer and a distribution layer.
