Wearable article having a temperature change element
First Claim
1. A wearable article worn about the lower torso of a wearer, the wearable article comprising a temperature change element including a permeable layer, an impermeable layer disposed in a face-to-face arrangement with the permeable layer, and a temperature change substance interposed between the permeable layer and the impermeable layer, wherein urine deposited onto the temperature change element can penetrate through the permeable layer in a z direction to the impermeable layer and wherein the impermeable layer prevents urine from passing completely through the temperature change element in the z direction and supports the movement of urine in an x-y plane to wet the temperature change substance.

Abstract
A wearable article useful for facilitating toilet training is provided. The wearable article includes a temperature change element providing a cool/wet signal when wetted which causes discomfort to the wearer. The temperature change element comprises a temperature change substance disposed on an impermeable material in order to maximize the thermal signal provided to the skin of the wearer.

9. A disposable diaper having a longitudinal axis, a first waist region, a second waist region, and a crotch region interposed therebetween, the disposable diaper comprising:
-
a backsheet;
a topsheet joined to the backsheet, the topsheet having a body-facing surface;
an absorbent core disposed intermediate the backsheet and the topsheet; and
a temperature change element disposed on the topsheet, the temperature change element including a permeable layer, an impermeable layer disposed opposite the permeable layer, and a temperature change substance interposed therebetween, wherein urine deposited onto the temperature change element can penetrate through the permeable layer in a z direction to the impermeable layer and wherein the impermeable layer prevents urine from passing completely through the temperature change element in the z direction and supports the movement of urine in an x-y plane to wet the temperature change substance. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 19, 20, 21, 22, 24, 26)

18. A disposable diaper having a longitudinal axis, a first waist region, a second waist region, and a crotch region interposed therebetween, the disposable diaper comprising:
-
a backsheet, a permeable topsheet joined to the backsheet, the topsheet having an upper body-facing surface and a lower surface;
an absorbent core disposed intermediate the backsheet and the topsheet; and
a plurality of temperature change elements disposed on the topsheet parallel to and spaced apart from the longitudinal axis, wherein the temperature change elements comprise permeable layers formed by the topsheet, impermeable layers formed by impermeable members interposed between the topsheet and the absorbent core, and a temperature change substance disposed on the topsheet, wherein urine deposited onto the temperature change element can penetrate through the topsheet in a z direction to the impermeable members and wherein the impermeable members prevent urine from passing completely through the temperature change element in the z direction and supports the movement of urine in an x-y plane to wet the temperature change substance.

23. A disposable diaper having a longitudinal axis, a first waist region, a second waist region, and a crotch region interposed therebetween, the disposable diaper comprising:
-
a backsheet;
a topsheet joined to the backsheet;
an absorbent core disposed intermediate the backsheet and the topsheet; and
a temperature change element disposed on the topsheet along the longitudinal axis, the temperature change element includes a permeable layer having a body facing surface, a temperature change substance disposed on the permeable layer, and an impermeable layer partially wrapped around the permeable layer such that longitudinal edges of the impermeable layer stop short of meeting, leaving a center portion of the body facing surface of the permeable layer exposed.

25. A disposable diaper having a longitudinal axis, a first waist region, a second waist region, and a crotch region interposed therebetween, the disposable diaper comprising:
-
a backsheet;
a top sheet joined to the backsheet;
an absorbent core disposed intermediate the backsheet and the topsheet; and
impermeable barrier leg cuffs disposed on the topsheet parallel to the longitudinal axis and temperature change elements disposed on the barrier leg cuffs, each of the temperature change elements includes a permeable layer having a body facing surface, an impermeable layer formed by the barrier leg cuff, and a temperature change substance disposed on the permeable layer.
