<p>There is provided a structurally simple exchangeable fastening device (51) of a disposable diaper that can be manufactured at low cost and is adapted to be fitted to a free end portion of a corresponding tape (50) of the diaper with ease and keep the diaper in a folded state after use to make the diaper ready for waste disposal. There is also provided a disposable diaper equipped with such fastening devices (51). The fastening device (51) of a surface fastener to be fitted to the free end portion of each of a pair of tapes (50) extending from opposite lateral side edges of one longitudinal end portion of the disposable diaper comprises a flexible strip-shaped substrate (52), first and second pressure-sensitive adhesive layers (53, 54) arranged at longitudinal opposite end portions of one surface of the substrate (52) and a male or female engaging surface area (55) arranged on the other surface of the strip-shaped substrate (52) opposite to the one surface carrying thereon said pressure-sensitive adhesive layers (53, 54) at a position opposite to said first pressure-sensitive adhesive layer (53). For releasably fitting the fastening device (51) to a corresponding fastening tape (50), the pressure-sensitive adhesive layers (53, 54) arranged at the longitudinal opposite end portions of the strip-shaped substrate (52) are made to face each other with the free end portion of the corresponding tape (50) pinched therebetween and the engaging surface area (55) facing a corresponding engaging surface area (60) so that the fastening device (51) may be releasably secured to the tape (50) by way of said pressure-sensitive adhesive layers (53, 54). <IMAGE></p> |
