Abstract
An absorbent article can have a chassis which can have a backsheet layer, a topsheet layer, and an absorbent system positioned between the backsheet layer and the topsheet layer. The absorbent system can have at least one absorbent layer which is a lobed absorbent layer. At least one flexure feature can associate with the lobed absorbent layer. A pair of non-integral wings can be bonded to the backsheet layer of the chassis.
Claims12
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.
