Abstract: A disposable diaper includes a body fluid absorbing zone extending over a crotch region further into front and rear waist regions, side flaps extending in a longitudinal direction outside transversely opposite side edges of the zone, and end flaps extending in a transverse direction outside longitudinally opposite ends of the zone. The side flaps in the front waist region are formed from a composite nonwoven fabric composed of a first fibrous nonwoven fabric facing away from the wearer's skin and a second fibrous nonwoven fabric laminated on the first fibrous nonwoven fabric and facing the wearer's skin. The first fibrous nonwoven fabric has a kinetic friction coefficient higher than a kinetic friction coefficient of the second fibrous nonwoven fabric.

Abstract: In a disposable diaper includes a pair of side flaps respectively extending from an end portion in a lateral direction of the diaper main body and a fixing tape disposed in proximity of a farthest edge of the respective side flaps, the fixing tape is provided with a hook member, the fixing tape and the side flaps are to be engaged via the hook member, and an engaging region on the side flaps where the fixing tape is to be engaged includes portions having a different engaging force with the hook member. As a result, the fixing tape can be temporarily fixed with a modest engaging force, despite the hook member having a greater engaging force.

Abstract: A diaper has two pairs of means adapted to connect transversely opposite side edge portions of a front waist region and a rear waist region. These connecting means are elastically stretchable in a transverse direction of the diaper and the connecting means lying at a lower portion of the side edge portions have a stretch stress a great as that of the connecting means lying at a upper portion of the side edge portions.

Abstract: A disposable diaper includes a basic absorbent batt structure and a supplementary absorbent batt structure placed thereon. An elastic member is provided between the two batt structures so as to transversely cross them. Contraction of the elastic member causes opposite side edge regions of the two batt structures to be pulled nearer to a longitudinal center line thereof. This results in a zone of the former batt structure underlying a distal end portion of the latter batt structure to curving downward with respect to a lower surface of the latter batt structure while the distal end portion of the latter batt structure curves upward with respect to a body facing surface of the basic absorbent batt structure. The curving of the batt structures forms a pocket opening from a front waist region toward a crotch region of the disposable diaper.

Abstract: A disposable diaper includes a liquid-impermeable topsheet, a liquid-permeable backsheet and an absorbent core therebetween. A pair of barrier cuffs which are elastically extendable in a longitudinal direction of the diaper are provided along transversely opposite side flaps of the diaper. Front and rear ends of the barrier cuffs are bonded to the diaper at longitudinally opposite ends thereof. Outer side edges of the barrier cuffs are bonded to outer edges of the flaps and inner side edges of the barrier cuffs are bonded to the flaps along lines defined between the outer side edges and transversely opposite side edges of the core.

Abstract: A disposable wearing article includes liquid-pervious topsheets, a liquid-impervious chassis and first and second liquid-absorbent panels. A first absorbent panel is covered with the topsheet and lies on the side of a front waist region. A second absorbent panel is interposed between the topsheet and chassis and continuously lies in a crotch region and a rear waist region. The first absorbent panel has a proximal end extending close to one of end flaps in a transverse direction and a first distal end supposed, along its transversely opposite side edges, to distal side edges of respective leakage-barrier cuffs so that an excrement receiving pocket adapted to open from the front waist region toward a crotch region is defined between the chassis and the first distal end of the first absorbent panel.

Abstract: A disposable diaper includes a basic absorbent batt structure and a supplementary absorbent batt structure placed on the basic absorbent batt structure. The diaper is formed with a feces receiving space surrounded by the supplementary absorbent batt structure and bottom and side surfaces of a cavity and extending from a crotch region toward a front waist region so that an upper opening of the cavity is partially uncovered in the crotch region 31 and thereby forms a feces inlet leading to the space.

Abstract: A disposable diaper includes a body fluid absorbing zone extending over a crotch region further into front and rear waist regions, side flaps extending in a longitudinal direction outside transversely opposite side edges of the zone, and end flaps extending in a transverse direction outside longitudinally opposite ends of the zone.
