Abstract
An absorbent article (100-1200) is capable of providing comfort to the wearer and can maintain dryness and inhibit the leakage of fluid. The absorbent article (100-1200) includes a multi-layered topsheet (138). The multi-layered topsheet (138) includes a first topsheet layer (106) having an opening (148) and a second topsheet layer (108) disposed under the first topsheet layer (106). The first topsheet layer (106) and the second topsheet layer (108) are joined together by a seal that, in one embodiment, generally corresponds with the shape of the opening (148). Further, a first sub-topsheet layer (116) is situated beneath the multi-layered topsheet (138) and has an opening (150) that is smaller than the first topsheet layer opening (148). This combination of openings (148, 150) situated one below the other provides for an absorbent article (100-1200) that can maintain a high level of dryness and its ability to conform to the wearer's body, and inhibit the leakage of bodily fluids due to a funnel-like effect.
