Absorbent articles with barrier leg cuffs

摘要

An absorbent article (20) for personal hygiene having a body-facing surface and an opposed garment-facing surface, the article having a front region (Z1), a back region (Z3) and an intermediate crotch region (Z2). The absorbent article comprises on each longitudinal side a gasketing cuff (32) and a barrier leg cuff (34) formed from the same web of nonwoven barrier material (110). The web of nonwoven barrier material is attached at least in the crotch region (Z2) to the topsheet by a plurality of mechanical and/or heat bonds (70), the plurality of mechanical and/or heat bonds defining in the crotch region a longitudinally extending bonding area (71) having a width W1. An adhesive (75) attaches in the crotch region the topsheet to the backsheet an that the adhesive covers at least 20% of the bonding area, this being also the case when the adhesive is notionally shifted laterally by any distance up to 4 mm.

1. An absorbent article for personal hygiene having a body-facing surface and an opposed garment-facing surface, the article having a front region, a back region and an intermediate crotch region, the absorbent article comprising:
a liquid pervious topsheet; a liquid impervious backsheet; an absorbent core disposed between the topsheet and the backsheet; wherein the absorbent article comprises on each of its longitudinal sides: a barrier leg cuff having a free distal edge, and an elastically contractible gasketing cuff disposed adjacent to a longitudinal edge of the absorbent article; wherein the gasketing cuff and barrier leg cuff are at least partially formed from the same web of nonwoven barrier material extending at least from the distal edge of the barrier leg cuff to the longitudinal side edge of the article; wherein the nonwoven barrier material is attached at least in the crotch region to the topsheet by a plurality of mechanical and/or heat bonds, the plurality of mechanical and/or heat bonds defining in the crotch region a longitudinally extending bonding area having a width W1; the absorbent article further comprising an adhesive attaching the topsheet to the backsheet at least in the crotch region; wherein the adhesive covers about 20% or more of the bonding area, this being also the case when the adhesive is shifted laterally by any distance of about 4 mm or less; wherein the adhesive comprises a plurality of longitudinally extending lines of adhesive, wherein each line has a width W2′ equal to about 20% or more of the width W1, and wherein each line is spaced from an adjacent line by a distance equal to about 4 mm or less so that at least one of the lines of adhesive covers the bonding area when the adhesive is shifted laterally by any distance of about 4 mm or less.
