Abstract

An absorbent article ( 10 ) can include a body facing liner ( 28 ), a backsheet ( 26 ), and an absorbent body ( 34 ) disposed between the body facing liner ( 28 ) and the backsheet ( 26 ). The body facing liner ( 28 ) can include at least one embossment ( 64 ). The absorbent article ( 10 ) can also include an acquisition layer ( 70, 170, 270, 370, 470 ) including a body facing surface ( 70 a ) and a garment facing surface ( 70 b ). The acquisition layer ( 70, 170, 270, 370, 470 ) can include at least one recess ( 90 ). The at least one recess ( 90 ) can receive the at least one embossment ( 64 ) in a nested configuration. In some embodiments, the embossment ( 64 ) can include an intersecting slit formation ( 78 ).

First claim

1 . An absorbent article including a longitudinal axis and a lateral axis, the absorbent article comprising:
a front waist region, a rear waist region, a crotch region, the crotch region being disposed between the front waist region and the rear waist region; a front waist edge in the front waist region, a rear waist edge in the rear waist region, and a first longitudinal side edge and a second longitudinal side edge, the first longitudinal side edge and the second longitudinal side edge each extending from the front waist edge to the rear waist edge; a body facing liner including a body facing surface and a garment facing surface, the body facing liner including at least one embossment; a backsheet; an absorbent body disposed between the body facing liner and the backsheet; and an acquisition layer including a body facing surface and a garment facing surface, the body facing surface of the acquisition layer including a planar portion, the acquisition layer including at least one recess that does not extend from the body facing surface of the acquisition layer to the garment facing surface of the acquisition layer, the at least one recess receiving the at least one embossment of the body facing liner in a nested configuration.

2 . An absorbent article including a longitudinal axis and a lateral axis, the absorbent article comprising:
a front waist region, a rear waist region, a crotch region, the crotch region being disposed between the front waist region and the rear waist region; a front waist edge in the front waist region, a rear waist edge in the rear waist region, and a first longitudinal side edge and a second longitudinal side edge, the first longitudinal side edge and the second longitudinal side edge each extending from the front waist edge to the rear waist edge; a body facing liner including a body facing surface and a garment facing surface, the body facing liner including at least one embossment, the embossment including an intersecting slit formation; a backsheet; an absorbent body disposed between the body facing liner and the backsheet; and an acquisition layer including a body facing surface and a garment facing surface, the acquisition layer including at least one recess, the at least one recess receiving the at least one embossment of the body facing liner in a nested configuration.

3 . The absorbent article of claim 2 , wherein the nested configuration provides that the garment facing surface of the body facing liner at the at least one embossment is disposed lower than the planar portion of the body facing surface of the acquisition layer when the absorbent article in a stretched, laid flat configuration.

4 . The absorbent article of claim 1 , wherein the at least one embossment includes an intersecting slit formation.

5 . The absorbent article of claim 2 , wherein the body facing liner includes a plurality of embossments and the acquisition layer includes a plurality of recesses, at least some of the plurality of recesses receiving one of the plurality of embossments of the body facing liner in a nested configuration.

6 . The absorbent article of claim 5 , wherein a majority of the plurality of embossments includes an intersecting slit formation.

7 . The absorbent article of claim 2 , wherein the at least one embossment includes a first depth and the at least one recess includes a second depth, and wherein the first depth is less than the second depth.

8 . The absorbent article of claim 5 , wherein a majority of the plurality of embossments includes a first depth and a majority of the plurality of recesses includes a second depth, and wherein the first depth is less than the second depth.

9 . The absorbent article of claim 5 , wherein a majority of the plurality of the embossments includes a first depth and a majority of the plurality of recesses includes a second depth, and wherein the first depth is about equal to the second depth.

10 . The absorbent article of claim 6 , wherein a majority of the plurality of embossments includes a first depth, and wherein the first depth is greater than a greatest slit length in the intersecting slit formation.

11 . The absorbent article of claim 6 , wherein a majority of the plurality of embossments includes a first depth, wherein a majority of the plurality of recesses includes a second depth, the first depth is less than the second depth, a greatest slit length in the intersecting slit formation being less than or equal to a difference between the second depth and the first depth.

12 . The absorbent article of claim 2 , wherein the recess of the acquisition layer extends through the acquisition layer from the body facing surface of the acquisition layer to the garment facing surface of the acquisition layer.

13 . The absorbent article of claim 2 , wherein the body facing liner includes a plurality of embossments and the acquisition layer includes a plurality of recesses, at least some of the plurality of recesses receiving one of the plurality of embossments of the body facing liner in a nested configuration, a majority of the plurality of recesses of the acquisition layer extending through the acquisition layer from the body facing surface of the acquisition layer to the garment facing surface of the acquisition layer.

14 . The absorbent article of claim 5 , wherein a majority of the plurality of recesses of the acquisition layer do not extend through the acquisition layer from the body facing surface of the acquisition layer to the garment facing surface of the acquisition layer.

15 . The absorbent article of claim 2 , wherein the acquisition layer includes a first layer and a second layer.

16 . The absorbent article of claim 15 , wherein the first layer includes fibers of a first average denier, and the second layer includes fibers of a second average denier, wherein the first average denier is greater than the second average denier.

17 . The absorbent article of claim 2 , wherein the acquisition layer includes at least one channel.

18 . The absorbent article of claim 5 , wherein the acquisition layer includes at least one channel, the at least one channel extends from a first recess of the plurality of recesses to a second recess of the plurality of recesses.

19 . The absorbent article of claim 5 , wherein the acquisition layer includes a plurality of channels, wherein at least some of the plurality of channels extend from a first recess to a second recess of the plurality of recesses.

20 . The absorbent article of claim 2 , wherein the at least one embossment includes a first volume and the at least one recess defines a second volume, and wherein the first volume is at least about ten percent less than the second volume.
