A pants-type disposable wearing article includes a liquid-impervious base sheet, a liquid-absorbent panel and transverse elastic members, each having opposite fixed portions secured to the lateral zones of the edges article, and a free portion extending in the transverse direction of the article between the opposite fixed portions across the panel and secured neither to the base sheet nor to the panel. The article further has leg-surrounding elastic members. At the crossover points of the transverse elastic members and the leg-surrounding elastic members, the elastic members are not secured one to another.

Pants-type disposable wearing article

A pull-on disposable wearing article is formed in a crotch region with first and second pairs of folding guide lines extending from first and second waist lateral margins toward a transverse middle of the crotch region, respectively. The crotch region is divided into a first zone enclosed by the first waist lateral margin and the first folding guide lines, a second zone enclosed by the second waist lateral margin and the second folding guide lines and a third zone outside the first and second zones. Inside the side edges of the core, first and second elastic members are contractible attached to the article. The first and second elastic members extend across the first and second zones to the third zone. The first and second zones are pulled inward under contractile forces of the elastic members to form tucks which are convex inwardly of the leg-holes.

Pull-on disposable wearing article with tapered folding guide lines and tucking zones

A disposable liquid-absorbent pad includes a liquid-pervious topsheet, a liquid-impervious backsheet and a liquid-absorbent core interposed between these two sheets. The pad is folded inwardly in the vicinity of transversely opposite side edges with the topsheet inside in a rear region, and folded outwardly in a transverse direction along folding lines extending in a longitudinal direction and joined together along the folding lines so that in the rear region of the pad defines an excretion receiving space extending up- and rearward to a rear end defining an apex and a pair of flanges extending outwardly from the respective folding lines to the side edges.

Disposable liquid-absorbent pad

A disposable wearing article has a pad member provided a pair of elastic thigh-tightening bands lying on transversely opposite side edges thereof. Front ends of first free zones and rear ends of second free zones of the respective elastic thigh-tightening bands are connected to the transversely opposite side edges in the vicinity of a waist-hole of pant member so that middle zones and first and second free zones of these thigh-tightening bands extend generally parallel to the respective leg-holes so as to substantially form loops.
