Abstract
A wearable article useful for facilitating toilet training. 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.
Claims9
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, wherein the topsheet is elastically foreshortened;
- an absorbent core disposed intermediate the backsheet and the topsheet;
- and
- a temperature change element attached to 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.
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
- 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;
- and
- wherein urine deposited onto the temperature change elements 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 elements in the z direction and supports the movement of urine in an x-y plane to wet the temperature change substance.

- and
- wherein the topsheet is permeable and wherein the temperature change element is interposed between the topsheet and the absorbent core such that at least a portion of the topsheet forms the permeable body facing surface of the temperature change element.
