Abstract
Abstract A diaper includes a flexible outer film impermeable to liquids and, on the inside surface of the outer film, longitudinal strips of adhesive and an absorbent pad. The pad has longitudinal edges set back from longitudinal edges of the outer film and transverse edges set back from transverse edges of the outer film. A flexible inner film permeable to liquids covers the inside surface of the outer film and the absorbent pad. It is adhesively bonded to the outer film in the area of contact between the films around the pad. Longitudinal elastic members are adhesively bonded while under tension to the outside surface of the outer film, along a central part of its longitudinal edge portions. The diaper also includes attachment means for fastening it around the body of the wearer and two flexible film tapes on the outside surface of the outer film over all its length and over a width that is greater than the width of the elastic members. These tapes enclose the elastic members.
