Abstract: A disposable pull-on diaper 1 having front and rear waist regions and a pair of tape fasteners secured to an outer surface of the front waist region or the rear waist region. Tape member forming each of the tape fasteners has a distal end portion and a proximal end portion wherein the distal end portion is releasably attached to joining zones along which the front and rear waist regions are joining together.

Abstract: A disposable wearing article comprises a liquid-pervious topsheet, a liquid-impervious backsheet and a liquid-absorbent panel interposed between the top- and backsheets. The backsheet is formed by a breathable and hydrophobic first fibrous nonwoven fabric layer underlying the panel, a breathable and liquid-impervious plastic film underlying the first fibrous nonwoven fabric layer and a breathable and hydrophobic second fibrous nonwoven fabric layer underlying the film. In a zone occupied by the panel, the first fibrous nonwoven fabric layer is intermittently joined to an under surface of the panel by means of a hot melt adhesive and the film is intermittently joined to the first fibrous nonwoven fabric layer by means of the hot melt adhesive.

Abstract: A disposable body fluid absorbent article includes a liquid-absorbent core. The core is provided in the vicinity of opposite side edges extending in a longitudinal direction with depressed regions tapering from an upper surface toward a lower surface of the core. A density of the core components in the depressed regions is lower then or equal to a density of the core components in the remaining region of the core.

Abstract: A disposable wearing article is provided on its garment facing surface with tape fasteners. The tape member forming each of the tape fastener has a fixed end portion and a free end portion adapted to be taken between the fingers longitudinally opposed to each other. The free end portion at least partially extend beyond the lateral edge of the wearing article.

Abstract: A pull-on disposable article has a liquid-absorbent first panel interposed between a liquid-absorbent sheet 2 and liquid-impervious sheets, a waist-hole and a pair of leg-holes. The leg-holes are surrounding by leg-surrounding flaps extending in a leg-surrounding direction outside transversely opposite side edges of the first panel. A transverse dimension between the transversely opposite side edges is minimized in the vicinity of bottoms of the respective leg-holes. The leg-surrounding flaps are formed with first folding lines extending in the leg-surrounding direction and second folding lines extending in a transverse direction. The leg-surrounding flaps are tucked along the first and second folding lines into the respective leg-holes.

Abstract: A disposable diaper is formed on its inner surface approximately in its longitudinally rear half area with a plurality of protuberances extending transversely across this rear half and intermittently arranged longitudinally of the diaper to thereby prevent loose fecal material from flowing forward and from leaking from a rear end of the diaper.

Abstract: A disposable pull-on garment has an elasticized waist-opening and a pair of elasticized leg-openings. At least one of the inner or outer surfaces of a peripheral edge of the waist opening includes a slippage resistant sheet. The sheet has a high friction coefficient so that the peripheral edge of the waist opening is easily and reliably gripped when the garment is pulled on by a wearer.

Abstract: The disposable pull-on undergarment that has first and second waist regions and a crotch region extending between these two waist regions. The waist regions are connected with each other in bonding zones extending along transversely opposite side edge portions thereof so as to define a waist-opening and a pair of leg-openings. First elastic members are bonded under tension to peripheral edge of the waist-opening and second elastic members are bonded under tension to peripheral edges of the leg-openings so that respective opposite ends of the first elastic members are positioned and fixed at first zones defined immediately inside the bonding zones in a circumferential direction of the waist-opening and respective opposite ends of the second elastic members are positioned and fixed at second zones defined immediately inside the bonding zones in a circumferential direction Y of the leg-openings.

Abstract: A disposable body fluid absorbent article includes, a liquid-absorbent core, the core is provided in the vicinity of opposite side edges extending in parallel to each other in a longitudinal direction thereof with depressed regions tapering from an upper surface toward a lower surface of the core and extending along a pair of imaginary lines extending in the longitudinal direction so as to describe convex curves respectively facing a center line bisecting a width of the core.

Abstract: A disposable sanitary article having elastic members extending to be associated with leg-openings secured under tension to the article along transversely opposite side edge portions of the sanitary article. The transversely opposite side edge portions respectively have first elastic zones extending across a crotch region in the longitudinal direction along a desired length, second elastic zones extending from the first elastic zones into a front waist region along a desired length and third elastic zones extending from the first elastic zones into a rear waist region along a desired length. The sections of the elastic members extending along the second elastic zones and the third elastic zones has values of stretch stress represented by a relationship of the second elastic zones<the third elastic zones or the third elastic zones<the second elastic zones.

Abstract: A disposable pull-on diaper includes a topsheet, a backsheet and an absorbent core disposed therebetween. In any one of front and rear waist regions of the diaper, second elastic members are disposed between the core and the backsheet to extend under tension circumferentially of the waist region and secured to the inner surface of the backsheet only at their portions extending outward beyond transversely opposite side edges.

Abstract: A disposable diaper has a garment facing surface. A backsheet defining the garment facing surface is provided on its outer surface with an adhesive tape adapted to hold the diaper in a rolled-up state. The adhesive tape comprises a fastening tape and a reinforcing tape. The fastening tape is folded back in an inner tape section and an outer tape section. The inner tape section is fixed in the vicinity of its end to the backsheet and spaced from the backsheet in the vicinity of a fold being contiguous to the outer tape section. The outer tape section is coated with an adhesive and temporarily fixed to the inner tape section. The reinforcing tape is folded back in two sections in a direction opposite to that in which the fastening tape is folded back and is fixed to the inner tape section in the vicinity of the fold 33 and also to the backsheet.
