Abstract

Configurable absorbent articles with improved bodily exudate visualization when viewing a wearer-facing surface are provided. The absorbent articles include a liquid permeable topsheet forming a portion of a wearer-facing surface of the absorbent article, a liquid permeable backsheet, and an absorbent core positioned at least partially intermediate the liquid permeable topsheet and the liquid permeable backsheet. The wearer-facing surface exhibits a Delta C* of greater than about 24 and less than about 50 when the absorbent article is subjected to a Bodily Exudate Visualization Test.

Claims (37)

1. An absorbent article configured to provide accurate bodily exudate visualization when viewing a wearer-facing surface of the absorbent article, the absorbent article comprising:

a liquid permeable topsheet forming a portion of the wearer-facing surface of the absorbent article;

a liquid impermeable backsheet comprising a first backsheet region having a first opacity and a second backsheet region having a second opacity, wherein the first opacity is less than the second opacity;

an absorbent core positioned at least partially intermediate the liquid permeable topsheet and the liquid impermeable backsheet; and

an outer cover nonwoven material comprising at least one window, wherein the window is formed by a first region of the outer cover nonwoven material having lower opacity than a surrounding second region;

wherein the wearer-facing surface exhibits a Delta C* of greater than about 24 and less than about 50 when the absorbent article is subjected to a Bodily Exudate Visualization Test.

2. The absorbent article of claim 1 , wherein the liquid permeable topsheet is in face-to-face contact with the absorbent core.

3. The absorbent article of claim 1 , wherein the absorbent article is free of a material between the topsheet and the absorbent core.

4. The absorbent article of claim 1 , wherein the absorbent article is free of an acquisition material.

5. The absorbent article of claim 1 , wherein the wearer-facing surface exhibits a Delta C* of greater than about 25 and less than about 50 when the absorbent article is subjected to the Bodily Exudate Visualization Test.

6. The absorbent article of claim 1 , wherein the wearer-facing surface exhibits a Delta C* of greater than about 28 and less than about 49 when the absorbent article is subjected to the Bodily Exudate Visualization Test.

7. The absorbent article of claim 1 , wherein a test fluid of the Bodily Exudate Visualization Test exhibits a Delta E* of less than about 42 and greater than about 25 when the absorbent article is subjected to the Bodily Exudate Visualization Test.

8. The absorbent article of claim 1 , wherein a test fluid of the Bodily Exudate Visualization Test exhibits a Delta E* of less than about 40 and greater than about 25 when the absorbent article is subjected to the Bodily Exudate Visualization Test.

9. The absorbent article of claim 1 , wherein the liquid permeable topsheet has a plurality of apertures defined therein.

10. The absorbent article of claim 1 , wherein the liquid permeable topsheet has an opacity in the range of about 20% to about 60% according to Opacity Test.

11. The absorbent article of claim 1 , wherein the absorbent article is free of a wetness indicator.

12. The absorbent article of claim 1 , wherein the absorbent core comprises an absorbent material comprising one or more layers of cellulosic material.

13. The absorbent article of claim 1 , wherein the absorbent core comprises an absorbent material that comprises superabsorbent polymers and that is free of air-felt.

14. The absorbent article of claim 1 , wherein the absorbent core comprises an absorbent material comprising a high internal phase emulsion foam.

15. The absorbent article of claim 1 , wherein the absorbent article is an insert.

16. The absorbent article of claim 1 , wherein the absorbent article is a diaper.

17. The absorbent article of claim 1 , wherein the absorbent article is an absorbent pad.

18. An absorbent article configured to provide representative bodily exudate visualization when viewing a wearer-facing surface of the absorbent article, the absorbent article comprising:

a liquid permeable topsheet forming a portion of the wearer-facing surface of the absorbent article, wherein the liquid permeable topsheet has a plurality of apertures defined therein;

a liquid impermeable backsheet comprising a first backsheet region having a first opacity and a second backsheet region having a second opacity, wherein the first opacity is less than the second opacity;

an absorbent core positioned at least partially intermediate the liquid permeable topsheet and the liquid impermeable backsheet; and

an outer cover nonwoven material comprising at least one window, wherein the window is formed by a first region of the outer cover nonwoven material having lower opacity than a surrounding second region, and wherein at least a portion of the at least one window overlaps at least a portion of the first backsheet region;

wherein a test fluid of the Bodily Exudate Visualization Test exhibits a Delta E* of less than about 40 and greater than about 25 when the absorbent article is subjected to a Bodily Exudate Visualization Test.

19. The absorbent article of claim 18 , wherein the wearer-facing surface exhibits a Delta C* of greater than about 28 and less than about 48 when the absorbent article is subjected to the Bodily Exudate Visualization Test, wherein the topsheet is in a face-to-face configuration with the absorbent core, wherein the absorbent article is free of an acquisition material and a distribution material, and wherein the liquid permeable topsheet is apertured.

20. An absorbent article configured to provide bodily exudate visualization when viewing a wearer-facing surface of the absorbent article, the absorbent article comprising:

a liquid permeable topsheet forming a portion of the wearer-facing surface of the absorbent article, wherein the topsheet comprises a plurality of apertures;

a liquid impermeable backsheet comprising a first backsheet region having a first opacity and a second backsheet region having a second opacity, wherein the first opacity is less than the second opacity;

an absorbent core positioned at least partially intermediate the liquid permeable topsheet and the liquid impermeable backsheet; and

an outer cover nonwoven material comprising at least one window, wherein the window is formed by a first region of the outer cover nonwoven material having lower opacity than a surrounding second region, and wherein at least a portion of the at least one window overlaps at least a portion of the first backsheet region;

wherein the liquid permeable topsheet is in face-to-face contact with the absorbent core;

wherein a test fluid of the Bodily Exudate Visualization Test exhibits a Delta E* of less than about 42 and greater than about 25 when the absorbent article is subjected to a Bodily Exudate Visualization Test; and

wherein the wearer-facing surface exhibits a Delta C* of greater than about 24 and less than about 50 when the absorbent article is subjected to the Bodily Exudate Visualization Test.
