Abstract: A disposable absorbent article, e.g., a diaper, and a method of manufacturing plural such articles. Each diaper includes a front section, a rear section and an intermediate section. Each section is a generally planar member formed of a flexible material having a top edge, a bottom edge and an opposed pair of side edges. The bottom edge of the front section is somewhat concave, and the bottom edge of the rear section is somewhat convex. The intermediate section is formed of a fluid pervious cover-stock, a fluid impervious barrier layer, and an absorbent core interposed therebetween. The intermediate section is of generally rectangular shape having a pair of elasticized sides and an pair of end portion one of which is adhesively secured to the middle of the front section, while the other end portion is similarly secured to the middle of the rear section. The front and rear sections are arranged to be releasably secured to each other by fastening tapes to mount the diaper.

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.

Abstract: An absorbent garment having a pant-like configuration is constructed using side leak guards which are seamless, and which exhibit improved performance. The seamless leak guards are provided by incorporating a substantially liquid-impermeable outer cover into the garment having lateral edges which extend substantially beyond the lateral edges of the absorbent layer. Elastic bands attached to the outer cover urge the edges upward during wear, and against the wearer's body, to prevent leakage of waste material. The portions of the outer cover which extend laterally beyond the absorbent layer serve as seamless leak guards.
