Patent ID: 6911574

Claim:
A body fluids absorbent article comprising: an absorbent structure having a longitudinal center line; a body facing surface; and an undergarment facing surface, said absorbent structure comprising: a liquid-pervious topsheet defining said body facing surface; a liquid-impervious backsheet defining said undergarment facing surface; and a liquid-absorbent core disposed between said topsheet and said backsheet, said absorbent structure inclusive of said body facing surface being formed in an upper layer thereof with a pair of compressed grooves, each of said compressed grooves having opposite terminal ends and a length extending between and to the opposite terminal ends, said compressed grooves being curved along the entire lengths thereof and being arranged in bilateral symmetry about said longitudinal center line, and extending continuously between longitudinal opposite ends of said absorbent structure, said topsheet being divided into a first absorbent surface zone extending in a central regions thereof and a second absorbent surface zone extending outward from said first absorbent surface zone, said first absorbent surface zone having a substantially smooth surface having no gathers and formed with a plurality of liquid-passages extending therethrough, said second absorbent surface zone having a plurality of gathers that extend substantially in parallel to said longitudinal center line, said first and second absorbent surface zones having boundary lines in transversely opposite side regions of said body facing surfaces that extend along said pair of compressed grooves.
