| Abstract | TITLE: SANITARY ABSORBENT ARTICLE HAVING A TEAR-RESISTANT FLANGE SEAL. A sanitary absorbent article such as a sanitary napkin, or incontinence pad having a cover layer that is fluid permeable, an absorbent system and a liquid- impervious barrier layer under the absorbent system to prevent collected liquid to escape therefrom. The fluid-permeable cover layer is attached to the liquid- impervious barrier layer to form a flange seal enclosing the absorbent system. The flange seal includes two zones, namely a first zone and a second zone separated by a common boundary, each zone manifesting different mechanical properties. The first zone that resides closer to the outer edge of the flange seal is more resistant to shear stresses than the second zone residing near the inner edge of the flange seal. This arrangement reduces the likelihood of the flange seal being torn during use of the sanitary absorbent article. (FIG.1) |
