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.
Claims31
A disposable absorbent article worn about a lower torso of a wearer and comprising:
- an absorbent core;
- and
- a temperature change element including a permeable layer, an impermeable layer disposed between the permeable layer and the absorbent core, 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 the impermeable layer prevents the 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:
- topsheet joined to the backsheet and having a body-facing surface;
- an absorbent core disposed intermediate the backsheet and the topsheet;
- and
- a temperature change element disposed on a portion of the topsheet covering a portion of the absorbent core and including a permeable layer, an impermeable layer disposed between the permeable layer and the topsheet, 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 the impermeable layer prevents the urine from passing completely through the temperature change element in the z direction and supports movement of the 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 and having a body-facing surface;
- an absorbent core disposed intermediate the backsheet and the topsheet;
- and
- a plurality of temperature change elements disposed parallel to and spaced apart from the longitudinal axis, each of the temperature change elements comprising a permeable layer formed by a portion of the topsheet covering a portion of the absorbent core, an impermeable layer interposed between the permeable layer and the absorbent core, and a temperature change substance disposed between the permeable layer and the impermeable layer,
- wherein urine deposited onto each of the temperature change elements can penetrate though the top in a z direction to the impermeable layer and the impermeable layer prevents the urine from passing completely through the temperature change element in the z direction and supports movement of the 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
- a temperature change element disposed on a portion of the topsheet covering a portion of the absorbent core along the longitudinal axis and including a 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 portion of a body facing surface of the permeable layer exposed, and a temperature change substance disposed 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 the impermeable layer prevents the urine from passing completely through the temperature change element in the z direction and supports movement of the 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;
- impermeable barrier leg cuffs the topsheet parallel to the longitudinal axis;
- and
- temperature change elements integrated with the barrier leg cuffs such that a portion of each of the barrier leg cuffs forms an impermeable layer of each of the respective temperature change elements, each of the temperature change elements also including a permeable body-facing layer disposed on the impermeable layer, and a temperature change substance disposed between the permeable layer and the impermeable layer,
- wherein urine deposited onto each of the temperature change elements can penetrate through the permeable body-facing layer in a z direction to the impermeable layer and the impermeable layer prevents the urine from Passing completely through the temperature change element in the z direction and supports movement of the 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 and having a body-facing surface;
- an absorbent core disposed intermediate the backsheet and the topsheet;
- and
- a temperature change element integrated with the topsheet such that a portion of the topsheet covering a portion of the absorbent core forms a permeable body-facing layer of the temperature change element, the temperature change element also including an impermeable layer disposed between the permeable body-facing layer and the absorbent core, and a temperature change substance disposed between the permeable layer and the impermeable layer;
- wherein urine deposited onto the temperature change element can penetrate through the permeable body-facing layer in a z direction to the impermeable layer and the impermeable layer prevents the urine from passing completely through the temperature change element in the z direction and supports movement of the urine in an x-y plane so as to wet the temperature change substance.
