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.
Claims29
A disposable absorbent article having a crotch section corresponding to a crotch region of a wearer and front and rear sections disposed at longitudinally opposite ends of the crotch section, said absorbent article comprising an inner surface intended to come in contact with the wearer's skin and an outer surface opposed to said inner surface, said inner surface being provided with at least one fecal matter retaining cavity adapted to receive fecal matter discharged on said inner surface, said at least one fecal matter retaining cavity being arranged so that, when said article is put on the wearer's body, said at least one fecal matter retaining cavity will be placed against a predetermined region of the wearer's hip extending around his/her anus;
- wherein:
- said absorbent article comprises a fecal matter retaining layer having a thickness of from about 5 to about 100 mm provided with said at least one fecal matter retaining cavity having an opening area of from about 20 to about 30000 mm2 and a depth of at least 2.5 mm;
- said retaining layer comprises a three dimensional network structure having air/water permeability in a thickness direction defined between said inner and outer surfaces and a planar direction intersecting said thickness direction at substantially the right angle and elastic compressivity in said thickness direction;
- and
- said retaining layer is present in all the front, crotch and rear sections of said absorbent article.
A disposable absorbent article, comprising a hydrophobic topsheet having an opening through which fecal matter can pass, a fecal matter retaining layer, a moisture absorbent layer and a liquid-impervious backsheet successively laminated one with another in this order so that said fecal matter retaining layer and moisture absorbent layer are enclosed between said topsheet and backsheet, wherein:
- said topsheet is formed with at least one said opening having an area of from about 20 to about 30000 mm2;
- said retaining layer is an elastic member having a thickness of from about 5 to about 100 mm, air/water permeability in a thickness direction and in a planar direction intersecting said thickness direction at substantially the right angle, elastic recovery of at least 50% from a compressed state in said thickness direction;
- and
- said retaining layer is provided with at least one fecal matter retaining cavity formed immediately below said opening of said topsheet so as to have substantially the same opening area as said area of said opening and a depth of at least 2.5 mm.
A disposable absorbent article having a crotch section corresponding to a crotch region of a wearer and front and rear sections disposed at longitudinally opposite ends of the crotch section, said absorbent article comprising a liquid permeable topsheet, a liquid impermeable backsheet, and a core completely enclosed between and by said topsheet and backsheet;
- wherein
- said core comprises a fecal matter retaining layer immediately beneath said topsheet, and a moisture absorbent layer beneath said retaining layer;
- said topsheet is formed with at least a through opening in a region that will be placed against a predetermined region of the wearer's hip extending around his/her anus when said article is put on the wearer's body;
- said retaining layer is an elastic, compression recoverable member having three dimensional air/water permeability, and said retaining layer is provided with at least a fecal matter retaining cavity formed corresponding to and immediately below said through opening of said topsheet;
- and
- said retaining layer is present in all the front, crotch and rear sections of said absorbent article.
