A pull-on disposable diaper includes in a waist covering region thereof a tape tab extending in a waist-circumferential direction. The tape tab includes a fixed tape section secured to an outer sheet of the diaper and a movable tape section contiguous to the fixed tape section. The movable tape section has a distal end portion and a proximal end portion. The distal end portion is formed with a finger grip zone and an attaching element located short of this finger grip zone. The proximal end portion is contiguous to one end portion of the fixed tape section. The attaching element is releasably attached to a zone of the fixed tape section in which the fixed tape section is curved to bulge in a direction spaced apart outwardly from an outer surface of the waist covering region.

Pull-on disposable diaper

A pull-on disposable wearing article has a first waist region and a second waist region. The first waist region is elastically stretch- and contractible in the transverse direction. The second waist region is formed with a pair of finger-grip zones which are non-stretchable in the transverse direction and an elastically stretch- and contractible middle zone. The finger-grip zones respectively have a dimension in a range of 10 to 100 mm as measured in the transverse direction and extend from a peripheral edge of the waist-hole to peripheral edges of the respective leg-holes, along a pair of bonded zones where transversely opposite side edges of the waist regions are bonded together. The middle zone extends between the finger-grip zones is elastically stretch- and contractible in the transverse direction.

A body fluid absorbing component of a pull-on disposable diaper is folded inward in a crotch covering region. Outside opposite side edges of the absorbing component, there are provided a pair of barrier walls extending in a longitudinal direction of the absorbing component. The barrier wall is provided along its zone opposed to an outer surface of the absorbing component, a distal edge of the barrier wall and an intermediate zone defined between the zone and the distal edge with first, second and third elastic members, respectively, each extending in a stretched state in the longitudinal direction of the absorbing component.

A disposable diaper that includes an outer sheet having thigh-surrounding peripheral side regions curving inwardly in a transverse direction and an inner pad disposed to the inner side of the outer sheet. The outer sheet is provide in thigh-surrounding peripheral side regions with first elastic members. The inner pad is provided in its side flaps with second elastic members. The first and second members cross one another in front and rear regions of the thigh-surrounding peripheral side regions and free regions of the side flaps are bonded at the cross regions of the first and second elastic members to the thigh-surrounding side regions, so that the first and second members are substantially connected to one another.

Disposable diaper pant

There is disclosed a disposable diaper including: an outer sheet facing outward; a liquid-permeable inner sheet facing a liquid receiving side; and an absorbent layer interposed between the outer sheet and the inner sheet, to form a front face portion to be applied to the abdomen of a wearer, an intermediate portion to be applied to the crotch, and a back face portion to be applied to the back side. A pattern sheet having a pattern and an area smaller than an area of the diaper, as viewed from the back face or the front face of the diaper, is adhered to the inner side of the outer sheet. The outer sheet allows the pattern to be observed therethrough.
