Abstract:
An absorbent article having a liquid pervious body-facing side, a liquid impervious garment side, a principal longitudinal centerline extending in a longitudinal direction, and a principal transverse centerline extending in a transverse direction, said absorbent article comprising:a main body portion having a central region, two spaced apart longitudinal side edges and two spaced apart end edges, said main body portion comprising an absorbent core positioned between said body-facing side and said garment side; anda pair of flaps joined to said main body portion at a juncture, each flap extending laterally outward beyond one of the longitudinal side edges of said main body portion in at least the central region of said main body portion to a distal edge, said flaps each having a flap transverse centerline that passes through said central region of said main body portion, said flaps comprising a proximal portion adjacent to said juncture and a distal portion located adjacent to the distal edge of said flaps, said flaps having a step configuration in which a portion of the flaps adjacent to the juncture is longer as measured in the longitudinal direction than a portion of the flaps located adjacent to the distal edges of the flaps and there is a discontinuity in the outer edge of the flaps between said proximal portion and said distal portion, and the length of the distal portions of the flaps as measured in the longitudinal direction is between about 50% and about 80% of the length of the proximal portions of said flaps, whereinsaid flaps comprise portions of said topsheet and said backsheet that extend laterally outward beyond the longitudinal side edges of said absorbent core from at least said central region of said main body portion, and said portions are partially peripherally joined together by adhesives, and are partially unbonded to leave an adhesive-free window at the interface between said portions of said topsheet and said backsheet that form said flaps.
