  • Absorbent article
    Patent number: 6300538
    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.

  • Method of securing a liquid impervious sheet to a wound pad
    Patent number: 6040492
    Abstract: A method of fastening a liquid-impervious sheet (7) to a wound pad (5) that is comprised of an elastic, hydrophilic material and that will expand in all directions when absorbing fluid. The pad (5) is stretched to a given extent both longitudinally and transversally in the plane of the pad and a flat liquid-impervious sheet (7) is then applied to the stretched pad and the load acting on the pad is removed. An absorbent dressing that includes an inventive wound pad (13) is also disclosed.
