Abstract
An absorbent article (10) such as a sanitary napkin, having an elongate absorbent core (12) delimited by an upper surface (14) and a lower surface (16), a pair of opposed longitudinal edge portions (18, 20) terminating in longitudinal edges (22, 24), and a pair of opposed transverse edges (26, 28). The core has a first end portion (30), a second end portion (32) and a mid portion (34) located between the end portions. The article further includes a liquid permeable topsheet (36) extending over the upper surface (14) and a liquid impermeable sheet (38) covering the longitudinal edge portions (18, 20) of the absorbent core (12). A strip of generally hydrophobic resilient material (40) is placed between the liquid impermeable sheet (38) and the absorbent core (12) along each longitudinal edge portion (18, 20) of the absorbent core in at least the mid portion (34) to thereby increase the flexure resistance of the article.
