Abstract
Abstract A multi-layer diaper includes a porous facing layer to be positioned adjacent an infant''s skin, an absorbent batt and a water-impervious backing sheet. The backing sheet is provided with adhesive tabs on its outer surface at its side portions near one end of the diaper, and is reinforced with flexible structural material, such as scrim, to prevent stretching and rupture thereof due to tension in the tabs generated during diapering, during the wearing of the diaper and during the removal of the diaper from the infant. The selected areas of reinforcement include the areas in the vicinity of tab permanent attachment to surface of the backing sheet, the front waist portion area, the marginal side portions, or the entire inner surface of the backing sheet.
