Abstract:
An absorbent article (100) comprising a liquid permeable nonwoven topsheet (226), a nonwoven second material (237) that is a separate material from the topsheet (226), a liquid impermeable backsheet (228), and an absorbent core (230) positioned intermediate the second material (237) and the backsheet (228). The second material (237) is positioned intermediate the topsheet (226) and absorbent core (230) and is generally planar. The topsheet (226) comprises a plurality of recesses (253) and raised areas (251), and voids (259) are defined in the raised areas (251) under the topsheet (226). A first aperture (275) is formed in a substantially central location of the raised areas (251). The recesses (253) each form a base positioned most distal from the substantially central locations of the raised areas (251). A second aperture (277) is formed in the bases (263) of the recesses (253). The first aperture (275) extends through the topsheet (226), and the second aperture (277) extends through the topsheet (226) and at least partially through the second material (237).
