Abstract

The present invention relates to an absorbent article for absorbing fluids and exudates, such as urine. More particularly, the present invention relates to absorbent garments which are configured to absorb body exudates while also helping to reduce the relative humidity in the environment of the article, to reduce skin-exudate contact and to reduced undesired skin hydration.

The present invention relates to an absorbent article having a front waist section, a rear waist section, and an intermediate section which interconnects said front and rear waist sections. One embodiment of the absorbent article generally includes: a topsheet having a body-facing surface; a backsheet; an absorbent; and a resilient material positioned between topsheet and the backsheet. The resilient material creates at least one contour which promotes movement of fluid away from one region of the article to another region of the article. The contour of the resilient material desirably creates a hill-like structure.

Claims

1. An absorbent article which defines a front section, a rear section, and an intermediate section which interconnects said front and rear sections, each section having at least one area or parts thereof, said absorbent article comprising:

a topsheet having a body-facing surface;

a backsheet;

an absorbent positioned between topsheet and the backsheet; and

a resilient material positioned above the absorbent material, wherein the resilient material creates at least one contour.

2. The absorbent article of claim 1, wherein the resilient material promotes movement of fluid away from one area of the article to another area of the article.

3. The absorbent article of claim 1, wherein the resilient material is positioned between topsheet and the backsheet.

4. The absorbent article of claim 1, wherein the resilient material is positioned on top of the topsheet.

5. The absorbent article of claim 1, wherein the intermediate section comprises, at least in part, a crotch region and wherein the resilient material is located in the crotch region of the article.

6. The absorbent article of claim 1, wherein the contour of resilient material creates at least one hill-like structure.

7. The absorbent article of claim 1 further comprising a surge material, said surge material being positioned between the topsheet and the backsheet.

8. The absorbent article of claim 1, wherein at least an area of at least one section of the article contains less absorbent than another area of the article.

9. The absorbent article of claim 1, wherein the absorbent is absent from the crotch region of the diaper.

10. The absorbent article of claim 1, wherein the absorbent is absent from the area of the article where the resilient material is positioned in the article.

11. The absorbent article of claim 1 further comprising a vapor barrier, said vapor barrier positioned between the absorbent and the topsheet;

wherein said vapor barrier reduces the amount of evaporative moisture the skin of a wearer is exposed to.

12. The absorbent article of claim 1, wherein the topsheet is liquid permeable.

13. The absorbent article of claim 1, wherein the backsheet is vapor permeable.

14. The absorbent article of claim 1, wherein the resilient material which promotes movement of fluid away from one area of the article to another area of the article comprises a foam-like material, elastomer, thermoplastic, open or closed cell foam, or plastic composites.

15. The absorbent article product of claim 1 is a personal care product.

16. The personal care product of claim 15, wherein the personal care product is selected from a diaper, training pant, absorbent underpant, adult incontinence product, sanitary wipe, wet wipe, feminine hygiene product, wound dressing, bandage, and mortuary and veterinary wipe, hygiene and absorbent product.

17. A composite which defines a front waist section, a rear waist section, and an intermediate section which interconnects said front and rear waist sections, each section having one or more regions, said absorbent article comprising:

a) a vapor permeable backsheet which defines a Water Vapor Transmission Rate of at least about 1000 grams per square meter per 24 hours calculated according to a Water Vapor Transmission Test as set forth herein;

b) a liquid permeable topsheet;

c) an absorbent body located between said backsheet and said topsheet; and

d) at least one undulation of resilient material located between said backsheet and said topsheet.

18. The composite of claim 17, wherein the at least one undulation is of sufficient elevation to provide for the movement of a fluid away from a region of the composite.

19. The composite of claim 17, wherein the at least one undulation is a hill or slope of material which provides for the direction of fluid to one or more regions of the composite.

20. The composite of claim 17, wherein the absorbent is essentially absent from one or more regions of the composite.

21. The composite of claim 17, wherein the intermediate section comprises, at least in part, a crotch region and wherein the resilient material is located in the crotch region of the article

22. The composite of claim 17, wherein the absorbent is essentially absent from the crotch region of the composite.

23. The composite of claim 17, wherein the backsheet is comprised of a highly breathable laminate.

24. The composite of claim 23, wherein the highly breathable laminate is a film/nonwoven laminate.

25. The composite of claim 24, wherein the nonwoven is a spunbond.

26. The composite of claim 17, wherein the backsheet has a WVTR value of at least about 2,500 g/m²/24 hr.

27. A diaper having a front waist section, a rear waist section, and an intermediate section which interconnects said front and rear waist sections, each section having one or more regions, said diaper comprising:

a) a vapor permeable outercover which defines a Water Vapor Transmission Rate of at least about 1000 grams per square meter per 24 hours calculated according to a Water Vapor Transmission Test as set forth herein;

b) a liquid permeable liner;

c) an absorbent body located between said outercover and said liner;

d) a surge layer;

e) a vapor barrier between the absorbent body and the liner; and

f) a resilient material, said material being positioned in the intermediate section of the diaper.

28. The absorbent article of claim 27, wherein the resilient material has sufficient elevation so as to provide for the flow of an insulting liquid to one or more other regions of the diaper so as to change the fluid profile in the diaper.

29. The absorbent article of claim 27, wherein the absorbent body is absent from the insult area of the absorbent article.

30. The absorbent article of claim 27, wherein said vapor permeable outercover is substantially liquid impermeable.
