Moisture Responsive Sealing Members In Disposable Absorbent Articles
January 1, 2008
Patented is a disposable absorbent article with a first longitudinal edge, a second longitudinal edge, a front waist edge and a rear waist edge. The disposable article comprises a backsheet, a topsheet bonded to the backsheet and an absorbent core between the topsheet and the backsheet. A first moisture responsive member is attached to the disposable absorbent article along at least one of the first longitudinal edge, the second longitudinal edge, the front waist edge and the rear waist edge of the disposable absorbent article outboard of the absorbent core. The moisture responsive member includes an elastomeric material adapted to sustain the fit of the disposable absorbent article to the body of a wearer prior to the moisture responsive member being wetted by moisture from the body of the wearer. The first moisture responsive member provides contact with a portion of the wearer’s body such that when the moisture responsive member is wetted by moisture from the wearer’s body, the first moisture responsive member expands against the portion of the wearer’s body to form a seal between the first moisture responsive member and the portion of the wearer’s body.
