A disposable diaper including a topsheet, and a topsheet is covered, at least in one of front and rear waist regions, with a liquid-resistant sheet bonded to a longitudinal end and transversely opposite side edges of that one of the front and rear waist regions; an elastic foamed member which is folded in two along a folding axis zone extending longitudinally thereof and has a first portion placed against the upper surface of the topsheet and a second portion placed against the lower surface of a liquid-resistant sheet is disposed between the topsheet and the liquid-resistant sheet in such a manner that the foamed member lies on an upper portion of a core in that one of the front and rear waist regions.

Disposable diaper

Training pants for infants include a pant body including of a topsheet, a backsheet and a water-impervious intermediate sheet disposed between the topsheet and the backsheet, and a wetness retaining sheet substantially made of hydrophilic fibers such as rayon. The wetness retaining sheet is bonded to the topsheet intermittently in longitudinal and transverse direction of the sheet. Zones of the wetness retaining sheet which are not bonded to the topsheet continuously extend in the transverse direction of the wetness retaining sheet.

Training pants for infants

A disposable body fluids absorbent article including a liquid-permeable topsheet 2, a liquid-impermeable backsheet and a liquid-absorbent core 4 disposed therebetween. The topsheet includes a hydrophobic first fibrous layer made of thermally meltable synthetic fibers having a fineness of 0.02.about.0.04 d, a hydrophobic second fibrous layer underlying the first fibrous layer and made of thermoplastic synthetic fibers and having a fineness of 1.0.about.2.5 d and a hydrophilic third fibrous layer underlying the second fibrous layer and made of thermally meltable synthetic fibers and having a fineness of 3.about.6 d. A plurality of hollows extend through the first and second fibrous layers so that these hollows are closed by the third fibrous layer so as to form a plurality of recesses.

Disposable body fluids absorbent article

A disposable absorbent article such as a disposable diaper including first stretchable side flaps extending over transversely opposite outer zones of the diaper and second stretchable side flaps functioning as liquid-barriers each having a proximal edge and a distal edge arranged so as to define an exposed zone of a topsheet along each of transversely opposite side edge surfaces of a liquid-absorbent core and thereby, if a quantity of liquid excretions gets over the distal edge of the second side flaps, it can be absorbed by the liquid-absorbent core through the exposed zones.

Disposable absorbent article

A disposable absorbent pad comprising a pad member adapted to present a boat-shape under the contractile force of elastic members contained in side flaps, and an elastic support member; longitudinally opposite of the pad member are connected to front and rear sides of the support member by end flaps each comprising top-and backsheets of the pad member and divided in a pair of end flap halves by a slit so as to function as a suspending strap; and the end flap halves are set apart in a V-shape with the slit therebetween as the support member is stretched and contribute to suspend the pad member with high stability.

Disposable absorbent pad

A disposable body fluids absorbent padding at least comprising a liquid-permeable topsheet, a liquid-impermeable backsheet and a liquid-absorbent core disposed between these two sheets, wherein said topsheet is made of a nonwoven fabric comprising high density zones and low density zones, and said high density zones have strips of liquid-impermeable thermoplastic film bonded to the upper surfaces of said high density zones.

Disposable body fluids absorbent padding

A disposable diaper so improved that a pair of flaps 17 extend from the transversely opposite side edges of an opening 16 centrally formed in the uppermost sheet 14 and these flaps 17 are provided along their outer side edges with elastic members 19, respectively, so that excretion can be reliably guided by sloped side walls formed by the flaps 17 to the opening 16.

Disposable diapers

Disposable training pants improved for effectively making babies wearing the training pants aware of their own excretions. There are provided on a topsheet of the pants a moistness holding sheet 11 having floating zones 11a serving as moistness sensor means.

Disposable training pants

A disposable diaper includes a semi-rigid absorbent body and high flexible side flaps disposed on laterally opposite the thereof. Each of said side flaps includes a first flap disposed outside the absorbent body and a second flap diverged from the first side flap. Each of the second flaps has the associated one of an elastic band incorporated therein and turned up under an elastic effect of the associated elastic band at least along a line of the divergence.
