Abstract
An absorbent article, such as a generally thin, flexible sanitary napkin with a topsheet, backsheet and absorbent core is provided. The absorbent article has a means for directional fluid distribution such as a fluid directing strip positioned between the topsheet and absorbent core, and an absorbent strip positioned between the topsheet and fluid directing strip. The relationships between the sizes of the fluid directing strip and the absorbent strip are such that the width of the fluid directing strip is greater than that of the absorbent strip and the length of the absorbent strip in greater than that of the fluid directing strip, so that bodily exudates may be directed toward the ends of the absorbent core even when the sanitary napkin assumes a body-conforming shape or is otherwise distorted during use.
