Abstract

An absorbent article includes a backsheet having a longitudinal axis, a topsheet attached to the backsheet and having a body-facing surface, and an absorbent core disposed between the backsheet and the topsheet. The article may also include barrier leg cuffs. The article further includes a sensation aspect, which sensation aspect may be provided between the core and the topsheet. The sensation aspect may be, for example, a temperature sensation aspect. A visible indicator may be associated with the sensation aspect.

First claim

What is claimed is:

1. An absorbent article comprising:
a backsheet;
a topsheet having a body-facing surface;
an absorbent core disposed between the backsheet and the topsheet, wherein the absorbent core includes a targeted zone of reduced absorbent capacity that absorbs less urine than surrounding areas of the core; and
a temperature sensation aspect that produces a change in temperature when wet, the sensation aspect including a carrier layer and a temperature sensation agent, the temperature sensation aspect being provided between the core and the topsheet; and
wherein the temperature sensation aspect is positioned on the targeted zone of reduced absorbent capacity on the core that correlates to a sensation aspect position of the core.

2. The absorbent article of claim 1 , wherein the temperature sensation agent is sorbitol.

3. The absorbent article of claim 2 , further comprising a three-dimensional film provided over the temperature sensation agent, the three-dimensional film being suited for reducing contact of the temperature sensation agent with skin.

4. The absorbent article of claim 1 , further comprising an acquisition layer between the absorbent core and the sensation aspect, wherein the acquisition layer wicks urine from the sensation aspect position of the core.

5. The absorbent article of claim 1 , wherein the sensation aspect comprises folds.

6. An absorbent article comprising:
a backsheet;
a topsheet having a body-facing surface;
an absorbent core disposed between the backsheet and the topsheet; and
a temperature sensation aspect that produces a change in temperature when wet, the temperature sensation aspect including a carrier layer and a temperature sensation agent, the temperature sensation aspect being provided between the core and the topsheet; wherein the temperature sensation aspect includes travel paths for urine flow wherein the travel paths comprise holes in the carrier layer for increased urine flow therethrough.

7. The absorbent article of claim 6 , wherein the temperature sensation agent is sorbitol.

8. The absorbent article of claim 6 , further comprising a three-dimensional film provided over the temperature sensation agent, the three-dimensional film being suited for reducing contact of the temperature sensation agent with skin.

9. The absorbent article of claim 6 , wherein the temperature sensation agent is provided in concentrated areas on the sensation aspect.

10. The absorbent article of claim 6 , wherein the carrier layer is hydrophilic.

11. An absorbent article comprising:
a backsheet;
a topsheet having a body-facing surface;
an absorbent core disposed between the backsheet and the topsheet, wherein the absorbent core includes a targeted zone of reduced absorbent capacity that absorbs less urine than surrounding areas of the core; and
a temperature sensation aspect that produces a change in temperature when wet, the temperature sensation aspect including a carrier layer and a temperature sensation agent, the temperature sensation aspect being provided between the core and the topsheet; wherein the temperature sensation aspect includes a graphic indicator for indicating placement or action of the sensation aspect; and
wherein the targeted zone of reduced absorbent capacity of the absorbent core is adjacent the temperature sensation aspect.

12. The absorbent article of claim 11 , wherein the sensation aspect has a color contrasting with a color of the absorbent article.

13. The absorbent article of claim 12 , wherein the color of the sensation aspect darkens when wet.

14. The absorbent article of claim 11 , wherein the graphic indicator appears when the sensation aspect becomes wet.

15. The absorbent article of claim 11 , further comprising an active graphic, the active graphic being triggered by activation of the sensation aspect.

16. The absorbent article of claim 15 , wherein the active graphic is provided on at least an exterior of the absorbent article.

17. The absorbent article of claim 15 , wherein the active graphic is provided on at least an interior of the absorbent article.

18. The absorbent article of claim 15 , the sensation aspect comprising a temperature sensation agent, wherein the graphic indicator is provided by coloring the sensation agent.
