Abstract:
A disposable diaper, comprising:a basic diaper structure comprising a liquid-pervious topsheet, a liquid-impervious backsheet, and a liquid-absorbent core disposed between said topsheet and said backsheet, longitudinally opposite ends of said basic diaper structure extending parallel to each other in a waist circumferential direction of the diaper; and a pair of tape fasteners extending outwards from transversely opposite side edges of said basic diaper structure, respectively, in said waist circumferential direction; each of said tape fasteners consisting essentially of a single hook member attached to a basic tape member which is elastically stretchable/contractile in said waist circumferential direction; said basic tape member having a longitudinal direction extending parallel to said waist circumferential direction and a transverse direction being orthogonal to said waist circumferential direction, said basic tape member having in said waist circumferential direction, a proximal end portion joined to one of the side edges of said diaper and a distal end portion opposed to said proximal end portion; and said hook member being attached to said basic tape member on an inner surface of said distal end portion so as to be spaced apart from said proximal end portion and having inner and outer side edges extending transversely of said basic tape member, and said inner side edge extends towards said proximal end portion in a transversely middle zone of said basic tape member; wherein an inelastic sheet member is disposed between said basic tape member and said hook member and covers the inner surface of said distal end portion.
