Abstract

A three-piece disposable absorbent article is disclosed having a longitudinal central axis and a transverse central axis. The disposable absorbent article includes front and back panels, each panel capable of being stretched and retracted in multiple directions. The back panel is also distinct and spaced apart from the front panel. The disposable absorbent article further includes an absorbent assembly situated between the front and back panels and which is attached to each by a first attachment member. The first attachment member is aligned along the longitudinal central axis. The disposable absorbent assembly includes a non-elastic absorbent that is capable of being elongated and contracted in only one direction, that direction being aligned approximately parallel to the transverse central axis.

Claims

1. A three-piece disposable absorbent article having a longitudinal central axis and

a transverse central axis, comprising:

a) a front panel capable of being stretched and retracted in multiple directions;

b) a back panel capable of being stretched and retracted in multiple directions, said back panel being distinct and spaced apart from said front panel; and

c) an absorbent assembly situated between said front and back panels and being attached to each by a first attachment member, said first attachment member being aligned along said longitudinal central axis, and said absorbent assembly including a non-elastic absorbent that is capable of being elongated and contracted in only one direction, that direction being aligned approximately parallel to said transverse central axis.

2. The three-piece disposable absorbent article of claim 1 wherein said absorbent assembly includes a liquid permeable bodyside liner and a liquid-impermeable backsheet which cooperate to enclose said non-elastic absorbent therebetween, and said bodyside liner and said backsheet are capable of being stretched and retracted in a direction parallel to said transverse central axis.

3. The three-piece disposable absorbent article of claim 2 wherein said bodyside liner and said backsheet are capable of being stretched and retracted in multiple directions.

4. The three-piece disposable absorbent article of claim 1 wherein said non-elastic absorbent has a length and a width, said length being aligned parallel to said longitudinal central axis and said width being aligned parallel to said transverse central axis, said width including a pair of planar regions separated by a non-planar region, and said non-planar region extending along said longitudinal central axis.

5. The three-piece disposable absorbent article of claim 4 wherein said non-planar region includes a plurality of alternating ridges and valleys.

6. The three-piece disposable absorbent article of claim 5 wherein each of said planar regions has an upper surface and a lower surface and each of said ridges has a peak that extends above said upper surfaces of each of said planar regions and each of said valleys has a bottom point that is evenly aligned with said lower surfaces of each of said planar regions.

7. The three-piece disposable absorbent article of claim 1 wherein said front and back panels are formed from an elastic material.

8. A three-piece disposable absorbent article having a longitudinal central axis and a transverse central axis, comprising:

a) an elastic front panel capable of being stretched and retracted in multiple directions;

b) an elastic back panel capable of being stretched and retracted in multiple directions, said back panel being distinct and spaced apart from said front panel; and

c) an absorbent assembly situated between said front and back panels and being attached to each by a first attachment member, said first attachment member being aligned along said longitudinal central axis, said absorbent assembly including a liquid permeable bodyside liner, a liquid-impermeable backsheet and a non-elastic absorbent positioned therebetween, said bodyside liner and said backsheet being secured together to completely enclose said non-elastic absorbent, and said non-elastic absorbent is capable of being elongated and contracted in only one direction when said backsheet is stretched and retracted, and that direction is aligned approximately parallel to said transverse central axis.

9. The three-piece disposable absorbent article of claim 8 wherein said bodyside liner and said backsheet are capable of being stretched and retracted in multiple directions.

10. The three-piece disposable absorbent article of claim 8 wherein said non-elastic absorbent has a length and a width, said length being aligned parallel to said longitudinal central axis and said width being aligned parallel to said transverse central axis, said width including a pair of planar regions separated by a non-planar region, and said non-planar region extending along said longitudinal central axis.

11. The three-piece disposable absorbent article of claim 10 wherein said non-planar region includes a plurality of alternating ridges and valleys.

12. The three-piece disposable absorbent article of claim 11 wherein each of said planar regions has an upper surface and a lower surface and each of said ridges has a peak that extends above said upper surfaces of each of said planar regions and each of said valleys has a bottom point that is evenly aligned with said lower surfaces of each of said planar regions.

13. The three-piece disposable absorbent article of claim 11 wherein each of said planar regions has an upper surface and a lower surface and each of said ridges has a peak that extends above said upper surfaces of each of said planar regions and each of said valleys has a bottom point that is aligned below said lower surfaces of each of said planar regions.
