Abstract

An absorbent article, such as a sanitary napkin is provided. The sanitary napkin of the present invention has a body-conforming configuration that is provided at least in part by a longitudinally-oriented resilient hump-forming element. The hump-forming element is positioned to form a hump along the longitudinal centerline on the body surface of the sanitary napkin. The sanitary napkin may also be provided with bending axes. The sanitary napkin may also be provided in a curved configuration.

Claims

1. An absorbent article comprising a main body portion having longitudinal sides and transverse ends, a body-facing surface and a garment-facing surface, said article comprising:

a liquid pervious topsheet on said body-facing surface;

a liquid impervious backsheet on said garment-facing surface joined to said to said topsheet;

an absorbent core positioned between said liquid pervious topsheet and said liquid impervious backsheet, said absorbent core having a central portion located

inward of said transverse ends and a center said raised center having a pair of transverse end portions;

said absorbent core further comprising at least one bending axis located longitudinally outboard of the transverse end portions of the raised center, at least a portion of said absorbent core comprising a material arranged in a structure that is resistant to wet collapse; and

a pair of flaps joined to said main body portion and extending outward along each longitudinal side thereof;

wherein said absorbent article preferentially bends at said bending axis.

2. The absorbent article of claim 1 wherein there are two bending axes located longitudinally outboard of the transverse end portions of the raised center.

3. The absorbent article of claim 1 wherein said portion of said absorbent core that is resilient when wet is more resilient than other portions of said absorbent core.

4. The absorbent article of claim 1 wherein said absorbent core at least partially comprises peat moss.

5. An absorbent article having longitudinal sides and transverse ends, a body-facing surface, and a garment-facing surface, said absorbent article comprising:

a liquid pervious topsheet on said body-facing surface;

an absorbent core adjacent said liquid pervious topsheet, said absorbent core having a central portion located inward of said transverse ends and a raised center comprising a material arranged in a structure that is resistant to wet collapse, said raised center having a pair of transverse end portions;

said absorbent core further comprising at least one transversely oriented bending axis located longitudinally outboard of the transverse end portions of the raised center; and

a liquid impervious backsheet on said garment-facing surface joined to said topsheet;

wherein said absorbent article preferentially bends at said bending axis.

6. The absorbent article of claim 5 wherein the absorbent core contains a transfer layer and a reservoir layer.

7. The absorbent article of claim 5 wherein said absorbent core at least partially comprises peat moss.

8. The absorbent article of claim 5 wherein there are two bending axes located longitudinally outboard of the transverse end portions of the raised center.

9. The absorbent article of claim 8 wherein the central portion of the absorbent core has a structural zone which is located between the bending axes.

10. The absorbent article of claim 8 wherein the absorbent article further contains flaps.

11. The absorbent article of claim 10 wherein the flaps are affixed to the absorbent article at positions between each bending axis.
