ABSORBENT ARTICLE CONTAINING APERTURES ARRANGED IN REGISTRATION WITH EMBOSSED WAVE PATTERN Russian patent published in 2016 - IPC A61F13/511 

FIELD: hygiene.

SUBSTANCE: absorbent article comprising a top sheet having embossed regions is provided. Embossed regions propagate in a longitudinal direction of article in form of a wave having alternating crests and troughs. Such a wave pattern helps slow down flow of bodily fluid by directing it along a tortuous path defined by densified edges rather than in a straight line. Among other things, this reduction in flow rate can help provide sufficient time for absorbent core to absorb fluid, which is particularly helpful when it is already partially filled with fluid. Nevertheless, bodily fluids can still sometimes pool near crests and/or troughs and result in leakage. To help counteract this tendency, it was discovered that a plurality of apertures can be employed in top sheet that are arranged in a column that generally extends in a longitudinal direction of article. At least a portion of apertures are located proximate to contiguous crests and/or contiguous troughs of embossed region.

EFFECT: without intending to be limited by theory, it is believed that registration of apertures with contiguous crests and/or contiguous troughs of embossed region puts them in a better position to receive bodily fluids that tend to pool around embossed regions and thus reduce likelihood of leakage.
