Abstract
A disposable absorbent article, e.g., a pantiliner, or other absorbent pad. The pad is an elongated generally planar member having a general hour-glass shape periphery including a pair of concave, side sections interconnecting respective ones of a pair of convex end sections. The pad basically comprises a top-sheet, a fluid absorbent core, and a cover sheet. The top sheet is formed of a fluid pervious material, e.g., a non-woven material, and is disposed over the absorbent core. The absorbent core comprises a fluid absorbing material, e.g., cellulosic fluff and super-absorbent particles, and is disposed over the cover sheet. The cover sheet is formed of a fluid impervious material, e.g., a plastic film. The top-sheet, the fluid absorbent core and the cover sheet are bonded, e.g., thermally bonded, together along plural concentric lines located adjacent the periphery of the pad. The plural concentric lines form a barrier resistant to the egress of fluid out of the periphery of the pad. The concentric lines include gaps therein to facilitate the bending of the pad. The gaps can be located at specific locations in the pad, e.g., between respective ones of adjacent end and side section…
