Abstract
Absorbent cores for use in absorbent articles are presented. The absorbent cores include a low-density zone that is surrounded by zones having a higher density than that of the low-density zone. The low-density zone aids in fluid absorption, distribution and storage.
Claims10
An absorbent article comprising an absorbent core, the absorbent core comprising a mixture of cellulosic pulp and superabsorbent polymer, where the core comprising the mixture defines:
- a single central zone comprising at least one insult area;
- a single continuous low-density zone surrounding the central zone, wherein the low-density zone is lower in density as compared to that of the central zone;
- a single perimeter zone surrounding the low-density zone, wherein the perimeter zone is higher in density as compared to that of the low-density zone;
- and
- a single outboard zone surrounding the perimeter zone;
- wherein the central zone, perimeter zone, and the outboard zone have the same density;
- wherein the central zone, low-density zone, and perimeter zone have the same thickness;
- and
- wherein the outboard zone has a thickness that is less than the thickness of the central zone, low-density zone and perimeter zone.
