Abstract:
A body exudates absorbent article comprising:a liquid-absorbent core having transversely opposite side edges extending in parallel to each other in a longitudinal direction; a liquid-pervious topsheet covering an upper surface of said liquid-absorbent core; and a liquid-impervious backsheet covering a lower surface of said liquid-absorbent core, said liquid-pervious topsheet and said liquid-impervious backsheet having inner surfaces that are bonded to one another along portions thereof that extend outward beyond longitudinally opposite ends of said liquid-absorbent core and outward beyond opposite side edges of said liquid-absorbent core, said liquid-pervious topsheet being formed in a zone covering said liquid-absorbent core with a plurality of alternating troughs and hollow crests continuously undulating in a transverse direction of said article and said troughs and hollow crests extending in said longitudinal direction, said liquid-absorbent core and said liquid-pervious topsheet being bonded to each other along a pair of compressed grooves which extend in said longitudinal direction in proximity to said transversely opposite side edges of said liquid-absorbent core, an upper surface of said liquid-pervious topsheet being covered with a barrier cover sheet which is formed in a zone corresponding to a central zone of said liquid-absorbent core with a longitudinal larger opening through which said troughs and said hollow crests of said liquid-pervious topsheet are exposed, said pair of compressed grooves lying in proximity to lateral side edges of said opening.
