  • Disposable liquid-absorbent article comprising pretensionally applied elastic means
    Patent number: 6210387
    Abstract: The invention relates to liquid-absorbent articles, including diapers, training pants, incontinence guards, and sanitary napkins. Characteristic for the invention is that at least one of the end portions of the absorbent body has a longitudinally tapering shape with a rounded outer edge and that an elastic means is pretensionally applied in a cover enclosing the absorbent body and extends across the article and in a curved path outside the rounded end portion of the absorbent body and equidistantly from the rounded edge. Due to its striving to contract, the elastic means in the curved path section exerts tensile forces across the elastic in a direction towards the center of curvature of the curved path section. When the article is in use, the elastic means, due to the tensile force, lifts the cover around the rounded edge of the absorbent body for formation of a leakage barrier which projects vertically above the absorbent body.
