Abstract
Abstract Improved absorbent article for diapers and the like comprising an outer backing sheet of a water impervious or repellant material, an optional inner top sheet having fluid passing properties, an absorbent pad therebetween, and a second water impervious or repellant interlayer sheet disposed between the top sheet and the absorbent pad. The interlayer has a plurality of spaced small holes therethrough. The interlayer and/or inner sheet are bonded directly to the outer sheet through the large holes in the absorbent pad. The outer margins of the layers may be sealed together. The construction shows improved penetration of fluid, substantially one-way transmission through the interlayer, and permits excellent spreading by the backing sheet. The bonding through the pad holes prevents pad shifting and balling in use without requiring a wadding sheet, and the edge margins around the holes provide added wicking surface for improved rate of absorption and retention. The inner sheet is preferably a non-woven material that minimizes skin contact with the plastic interlayer, providing a smooth hand surface.
