Abstract

An absorbent article with improved body fit wherein a combination of downward-deflecting crease lines and an upward-deflecting shaping line are used in outer and central absorbent members, respectively, to achieve a form-fitting geometry in the crotch region while also enhancing control over fluid flow in the article. Embodiments with wicking barriers between the outer and central absorbent members are especially useful in achieving leakage reduction.

Description

Background of the invention [0001] In absorbent articles of the prior art, there is a need for articles with improved fit properties. For sanitary napkins in particular, advances in absorbent materials and covers provide little benefit in practice if the user's fluids do not reach the intended absorbent area of ​​the article. Significant gaps between the human body and the absorbent area of ​​the pad can cause liquid to run along the body and stain the garment. Also, fluids from the body are not effectively removed, resulting in a wet, unclean feeling. [0002] Much effort has been made to improve fit performance. Three-dimensional articles have been proposed having a thick central region of fluff pulp, foam or other loose material forming pads designed to conform to a woman's body in use. However, such articles are loose, resulting in high cost and inconvenience since only a relatively small number of articles can be packed into the pad. Furthermore, interviews with women...
