Abstract
Official abstract text for this publication.
Provided are a bodily fluid absorbent article improved to absorb bodily fluids quickly and a method for making a core for the bodily fluid absorbent article. A bodily fluid absorbent core for a bodily fluid absorbent article is formed with one or more elongated depressions. The core 40 includes one or more surface layers and one or more inner sections lying inside the one or more surface layers. The one or more surface layers are formed primarily of liquid-absorbent fibers and the one or more inner sections are formed of the liquid-absorbent fibers and superabsorbent polymer particles.
First claim
Opening claim text (preview).
The invention claimed is: 1. A bodily fluid absorbent article, comprising: a bodily fluid absorbent core having a predetermined thickness and including therein liquid-absorbent fibers and superabsorbent polymer particles; a liquid-pervious sheet covering a skin-facing surface of the core; a liquid-impervious sheet covering a non-skin-facing surface of the core; and elastic members secured under tension to the liquid-impervious sheet, wherein the non-skin-facing su…
