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 body fluid absorbent panel including fibers containing hydrophilic fibers by 80-100% by weight and superabsorbent polymer particles contains heat-fusible fibers which are fused to intertwine the fibers and thereby to form a three-dimensional network structure wherein the high absorption polymer particles are held between respective pairs of the adjacent fibers or bonded to the fibers by means of binder, and thereby falling off of the polymer particles can be prevented and the absorption efficiency can be improved.

Abstract: A disposable diaper is locally formed with a protuberance in a transversely middle zone of the diaper between urethral meatus and anus of a diaper wearer, and the diaper thus formed is capable of preventing loose passage discharged thereon form flowing toward the front side of the wearer.

Abstract: A sanitary article includes an absorbent structure composed of a liquid-pervious topsheet, a liquid-impervious backsheet and a liquid-absorbent core disposed therebetween, an absorbent upper panel which is formed with a fibrous web and attached to an upper surface of the topsheet. The absorbent upper panel has a plurality of openings extending through the panel in its thickness direction and spaced one from another in a direction intersecting the thickness direction and a wall defining each of the openings wherein the wall has a fiber density grade which is higher in an upper region of the wall and lower in a lower region of the wall lying adjacent the topsheet.

Abstract: An absorbent article contains a hydrophilic fiber processed by a water-soluble deodorant containing a graft polymer having a deodorant functional group. This constitution ensures to have large deodorizing function per unit weight, compared to a particulate deodorant. Consequently, the constitution allows to decrease a weight of the deodorant and to excel in deodorizing function. Moreover, it is unnecessary to fix the deodorant and easy to compound with the absorbent article. Therefore, it allows to obtain an absorbent article having excellent aesthetics and cleanness.

Abstract: A sanitary article having a multi-layered absorbent member includes a panel stacked in two layers each having a plurality of openings extending through this member in its thickness direction and a plurality of fibrous assembly regions extending between each pair of the adjacent openings, the openings in the upper layer of the panel are out of alignment with the corresponding openings in the lower layer of the panel and each of the openings in the upper layer of the panel is divided in two or more sections by the fibrous assembly regions in the lower layer of the panel.

Abstract: A disposable absorbent article including a fecal matter retaining layer, the retaining layer including a three dimensional structure having a thickness of 5˜100 mm adapted to be placed against a wearer's hip is formed with at least one opening having an area of 20˜30000 mm2 and at least one fecal matter retaining cavity having a depth of 2.5 mm.

Abstract: A disposable diaper includes tape fasteners each having an elastically stretchable/contractile basic tape member and a hook member attached onto an inner surface of the basic tape member. The hook member has inner and outer side edges. and the inner side edge extends towards a proximal end portion of the basic tape member in its transversely middle zone.

Abstract: A disposable article for dealing with feces adapted to be used in conjunction with a disposable diaper or diaper cover. The article includes a feces receiving region that is provided in the form of a laminate that includes a top layer provided with at least one opening having an area of 20˜500 mm2, a feces holding layer in the form of a three-dimensional network structure underlying the top layer, a liquid-absorbent layer underlying the holding layer and a liquid-impervious back layer covering a lower surface of the absorbent layer. The laminate has its width progressively reduced toward a front end of the feces receiving pocket and a leakage barrier is formed along transversely opposite side edges of the top layer.

Abstract: A disposable diaper includes a basic absorbent batt structure and a supplementary absorbent batt structure placed thereon. Contraction of an elastic member causes transversely opposite side edge regions of the two batt structures, respectively, to be pulled nearer to a longitudinal center line, resulting in that the zone of the former batt structure underlying a distal end portion of the latter batt structure curves 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 two batt structures, a pocket opening from a front waist region toward a crotch region.

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 basic absorbent batt structure having front and rear waist regions and a crotch region, a pair of barrier cuffs extending along opposite sides of the basic absorbent batt structure and at least one supplementary absorbent batt structure placed on the front waist region of the basic absorbent batt structure between the barrier cuffs. The supplementary absorbent batt structure has a proximal end portion thereof joined to the front waist region of the basic absorbent batt structure and has the vicinity of a distal end portion thereof joined to the vicinities of the barrier cuffs.
