Abstract
Disclosed is an absorbent article including a temperature change member. In addition to the temperature change member, the article can include an outercover, and an absorbent body disposed on the outercover. The temperature change member includes temperature change material that is disposed in a temperature change composite in a nonuniform distribution.
Claims38
An absorbent article defining a longitudinal direction, a lateral direction perpendicular to said longitudinal direction, and a z-direction perpendicular to a plane defined by said lateral direction and said longitudinal direction, said absorbent article comprising:
- A liquid impermeable outercover;
- An absorbent body disposed on said outercover;
- and
- A temperature change member disposed with said absorbent body, said temperature change member defining a member inner surface and a member outer surface opposite said member inner surface, and comprising a temperature change composite, said temperature change composite comprising temperature change material disposed in a nonuniform distribution by weight in said z-direction and wherein said temperature change member provides said article with a temperature change when wet of at least 5 degrees C., as determined by the temperature change test described herein.
An absorbent article comprising:
- A liquid impermeable outercover;
- An absorbent body disposed on said outercover;
- and
- A temperature change member disposed with said absorbent body, said temperature change member defining a member inner surface and a member outer surface opposite said member inner surface, and comprising a temperature change composite, said temperature change composite comprising temperature change material wherein at least 50 percent of said temperature change material defines a particle size of at least 500 microns by weight and wherein at least 0.5 mm of said temperature change member-adjacent said member inner surface is substantially free of temperature change material to define a first isolation zone and wherein said temperature change member provides said article with a temperature change when wet of at least 5 degrees C., as determined by the temperature change test described herein.
An absorbent article comprising:
- A liquid impermeable outercover;
- An absorbent body disposed on said outercover;
- and
- A temperature change member disposed with said absorbent body, said temperature change member comprising temperature change material wherein at least 10 percent of said temperature change material has a particle size not greater than 200 microns and at least 10 percent of said temperature change material has a particle size of greater than 500 microns and wherein said temperature change member provides said article with a temperature change when wet of at least 5 degrees C., as determined by the temperature change test described herein.
