Abstract
A disposable diaper put on by means of pressure-adhesive tape, has a liquid-permeable inner layer closest to the user during use of the diaper, a liquid-tight outer layer, and an absorbent layer disposed between the inner and outer layers. Tape tabs at one end of the diaper close to the corners of the diaper have a portion permanently joined to the liquid-tight outer layer at that diaper end. A plastic strip for fastening the tape tabs when putting the diaper on the user is disposed on the opposite end of the diaper and consists of a material which is inelastic and has suitable properties for fastening the tape tabs as well as removing and refastening the tape tabs. The plastic strip is elongated transversely of the diaper to permit adjustment of the tension of the diaper around the user by loosening and refastening the tape tabs. The strip extends across the width of the diaper on the outside of the liquid-tight outer layer. The tabs are also fastened to the same side of the liquidtight outer layer.
