Abstract
A disposable diaper with stretchable longitudinal seals. The diaper includes an absorbent pad between a liquid-tight outer backing sheet and a liquid-pervious inner surface sheet including an elongate opening. Two first longitudinal folds extend over the length of the diaper on either side of the longitudinal opening so that each fold defines a closed sleeve including a stretched resilient member. At least two additional longitudinal folds extend over the length of the diaper and are arranged between the first longitudinal folds and a longitudinal region in which the surface sheet is attached to the diaper.
