A disposable absorbent undergarment such as a diaper includes short pants and a liquid-absorbent pad attached to an inner surface of the short pants. The short pants has a front waist section, a rear waist section, a crotch section interposed therebetween, a waist-opening and a pair of leg-openings. The crotch section, the waist-opening and the leg-openings are elastically stretchable. A circumferential region defined by portions of the front and rear waist sections between the waist opening and upper ends of the leg-openings is also elastically stretchable.

Disposable absorbent undergarment

A well-fitting disposable diaper having a front gathering to be applied to the crotch of a wearer. The front gathering is formed by elastic members disposed about a border between a crotch region and a front waist region of the diaper and includes one end portions of first and second thin parts which are disposed in the crotch region and the front waist region, respectively. Because the first thin parts are elongated between the second thin parts in the front gathering, the front gathering can readily shrink to press the crotch of a wearer or a protector against incontinence to be applied thereto.

Disposable diaper

A folded disposable diaper to be packed in a package while being folded inwardly about two first folding lines extending in a longitudinal direction of the diaper and then folded inwardly about two second folding lines extending in a transverse direction thereof perpendicular to the longitudinal direction. The diaper includes an absorption core having four thin areas and one thick area. The thickness of the diaper at the thin area is equal to or less than one half of the thickness of the diaper at the thick area. The first folding line is positioned outside of the center of the thin area in the transverse direction. Therefore, when the diaper is folded about the first folding lines, each of the thin areas is folded on itself to prevent an increase in the thickness of the folded diaper, while maintaining the absorbency of the absorption core.

Foldable disposable diaper

A pull-on disposable diaper has front and rear waist regions and a crotch region extending therebetween. A waist-opening of the diaper is provided with elastic members being stretchable circumferentially of the waist-opening. An absorbent core has a front end lying below the elastic members and a rear end extending above the elastic members.

Pull-on disposable diaper

A disposable absorbent article according to the invention comprises a liquid-absorbent core provided intermittently in longitudinal and transverse directions thereof with a plurality of linear slits extending therethrough extending longitudinally of the article and thereby promote spread of body fluids.

Disposable absorbent article

An absorbent pad comprising a pad proper adapted to present a boat-shape under the contraction of elastic members contained in respective side flaps, front and rear ends of said pad proper being connected to front and rear ends of an annular elastic waist band by respective pairs of elastic suspending straps.

Disposable absorbent pad

Disposable garment for absorption of body exudates

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.

A disposable garment of pants type, such as a disposable diaper of pants type, is constructed by attaching respective leg-hole surrounding flaps and waist-hole surrounding flaps to respective opposite side edges extending longitudinally of a basic assembly for the garment which comprises at least a topsheet and a backsheet. The leg-hole surrounding flaps and the waist-hole surrounding flaps respectively cooperate to form a pair of leg-holes. A pair of shoulder straps can be easily prepared by making a slit which extends longitudinally of the garment on each waist-hole surrounding flap. A disposable garment of the present invention is featured in its simple construction and easy production.
