Abstract

A disposable absorbent article defined by a pair of longitudinally extending side edges and a pair of end edges extending between the side edges, has a front waist region, a back waist region, and a crotch region located between the waist regions. The disposable absorbent article also includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet. The topsheet is provided with a plurality of openings which direct bodily exudates received into or by the crotch region to a storage space disposed below the topsheet. The topsheet is spaced generally upward from the core such that the storage space is disposed between the topsheet and the core. The disposable absorbent article further includes at least one or more elongated elastic strands which are attached to the topsheet so as to space or urge the topsheet generally upwardly from the core. Moreover, portions of the topsheet between the elastic strands are tacked down to create depressions between the strands and each of the openings are located generally in one of these depressions.

1. A disposable absorbent article having a front waist region, a back waist region, and a crotch region located between said front and back waist regions, said article comprising:

a backsheet;

a plurality of absorbent cores, said cores being generally spaced apart from one another and disposed above said backsheet and generally in said crotch region; and

a topsheet disposed above said plurality of absorbent cores, said topsheet being equipped with a plurality of spaced apart elastic strands which are attached thereto to form a plurality of spaced apart ridges, wherein said strands are adapted to bias said topsheet upwardly and wherein portions of said topsheet located between said strands are tacked down to form depressions between said ridges; and

wherein said topsheet is further equipped with a plurality of openings located between said ridges, said openings being adapted to direct bodily exudates received in said crotch region toward said cores;

wherein said topsheet is tacked down at locations between said cores and at least a number of said openings are generally located between said cores;

wherein said storage space is generally located below said cores, said storage space being generally adapted for storage of a solids portion of said bodily exudates; and

wherein said topsheet includes generally inclined walls directed downwardly from said ridges to said openings.

2. The article of claim 1, wherein each of said openings has a lateral width substantially less than the lateral distance between said ridges.

3. A disposable absorbent article having a front waist region, a back waist region, and a crotch region located between said front and back waist regions, said article comprising:

a backsheet;

a plurality of absorbent cores disposed above said backsheet and generally in said crotch region, said cores being generally spaced apart from one another; and

a topsheet disposed above said absorbent core, said topsheet being equipped with a plurality of spaced apart elastic strands which are attached thereto to form a plurality of spaced apart ridges, wherein said strands are adapted to bias said top sheet upwardly and wherein portions of said topsheet located between said strands are tacked down to form depressions between said ridges; and

wherein said topsheet is further equipped with a plurality of openings located between said ridges, said openings being adapted to direct bodily exudates received in said crotch region toward said core;

wherein said topsheet is tacked down at locations between said cores and each of said openings is generally located between said cores; and

wherein storage space is generally located below each of said cores, said storage space being generally adapted for storage of the solids portion of said bodily exudates.

4. The article of claim 3, wherein said topsheet includes generally inclined side walls directed downwardly from said ridges to said openings.

5. The article of claims 3, wherein each of said openings has a lateral width substantially less than the lateral distance between said ridges.
