Abstract

The invention encompasses an absorbent article having a shape so as to guard against leakage, especially when the wearer is in a prone or supine position. In one embodiment, the absorbent article comprises a body, including an exudate impermeable backsheet, and exudate permeable topsheet that is attached to the bottom sheet, and an absorbent core that is positioned between the backsheet and topsheet. Further, a front end comprises a first upraised peak, while a back end comprises a second upraised peak, with a central portion extending between the first and second upraised peaks.

Claims

1. An absorbent article for absorption of human exudate, comprising:

a body including;

an exudate impermeable backsheet;

an exudate permeable topsheet attached to the backsheet; and

an absorbent core positioned between the topsheet and backsheet, wherein said body includes;

a front end comprising a first upraised peak;

a back end comprising a second upraised peak; and

a central portion extending between said first and second upraised peaks, said center portion having a height less than a height of said first and second upraised peaks.

2. The absorbent article of claim 1, wherein said body includes two lateral sides.

3. The absorbent article of claim 2, further comprising wings extending perpendicular from the lateral sides.

4. The absorbent article of claim 2, wherein said wings are positioned perpendicular to the lateral sides of the central portion.

5. The absorbent article of claim 1, wherein said first upraised peak rises sharply from the front end, and gradually declines towards the center portion.

6. The absorbent article of claim 1, wherein said second upraised peak rises sharply from the back end, and sharply declines towards the center portion.

7. The absorbent article of claim 1, wherein said first and second upraised peaks are of equal height.

8. The absorbent article of claim 1, wherein said first upraised peak is shorter than said second upraised peak.

9. The absorbent article of claim 1, wherein said first upraised peak is higher than said second upraised peak.

10. The absorbent article of claim 1, wherein said first upraised peak has a first slope greater than 1.

11. The absorbent article of claim 1, wherein said second upraised peak has a second slope less than 1.

12. The absorbent article of claim 1, further comprising a means for maintaining said absorbent article in operable association with the wearer.

13. An absorbent article for use on the body of a wearer, comprising:

a body having a longitudinal axis, said body including;

an exudate impermeable backsheet;

an exudate permeable topsheet attached to the backsheet; and

an absorbent core positioned between the topsheet and backsheet, wherein said body includes;

a front end comprising a first upraised peak;

a back end comprising a second upraised peak;

a central portion extending between said first and second upraised peaks, said center portion having a height less than a height of said first and second upraised peaks.

14. The absorbent article of claim 13, further comprising a means for maintaining said absorbent article in operable association with the wearer.

15. The absorbent article of claim 14, wherein the means for maintaining said absorbent article in operable association with the wearer comprises an adhesive.

16. An absorbent article for absorption of human exudate, comprising:

a body having a longitudinal axis, including;

an exudate impermeable backsheet;

an exudate permeable topsheet attached to the backsheet; and

an absorbent core positioned between the topsheet and backsheet, wherein said body exhibits undulation when viewed in a cross-section taken along said longitudinal axis.

17. The absorbent article of claim 16, wherein said body includes a front end, a back end, a center portion, and two lateral sides.

18. The absorbent article of claim 17, further comprising wings positioned perpendicular to the lateral sides.

19. The absorbent article of claim 17, wherein said wings are positioned perpendicular to the lateral sides of the central portion.
