摘要：
An absorbent article that contains a topsheet having embossed regions is provided. The embossed regions propagate in a longitudinal direction of the article in the form of a wave having one or more alternating crests (peaks) and troughs (valleys). Such a wave pattern helps slow down the flow of bodily fluid by directing it along a tortuous path defined by the densified edges rather than in a straight line. Among other things, this reduction in flow rate can help provide sufficient time for the absorbent core to absorb the fluid, which is particularly helpful when it is already partially filled with fluid. Nevertheless, bodily fluids can still sometimes pool near the crests and/or troughs and result in leakage. To help counteract this tendency, the present inventors have discovered that a plurality of apertures can be employed in the topsheet that are arranged in a column that generally extends in a longitudinal direction of the article. At least a portion of the apertures are located proximate to contiguous crests and/or contiguous troughs of the embossed region. Without intending to be limited by theory, it is believed that the registration of the apertures with contiguous crests and/or contiguous troughs of the embossed region puts them in a better position to receive bodily fluids that tend to pool around the embossed regions and thus reduce the likelihood of leakage.La présente invention concerne un article qui comprend une feuille supérieure ayant des régions gaufrées. Les régions gaufrées se propagent dans une direction longitudinale de larticle sous la forme dune vague ayant une ou plusieurs crêtes (pics) et creux (vallées) alternés. Un tel motif gaufré aide à ralentir le flux de fluide corporel en dirigeant ledit flux le long dune trajectoire tortueuse définie par les bords densifiés plutôt quen ligne droite. Cette réduction du débit aide, entre autres, à laisser suffisamment de temps pour que le cœur absorbant absorbe le fluide, ce qui est particulièrement
