Absorbent article with center fill performance
First Claim
1. An absorbent article having a longitudinal direction, a transverse direction, a vertical direction substantially normal to both the longitudinal and transverse directions, and a body side, the absorbent article comprising:
- a) an absorbent core having a body side surface, the absorbent core comprising an outer absorbent member having a void centrally disposed therein, the centrally disposed void open toward the body side of the absorbent article, and a central absorbent member disposed over the centrally disposed void of the outer absorbent member and extending into the centrally disposed void; and
b) a wicking barrier disposed between the outer absorbent member and the central absorbent member, the wicking barrier comprising a vertical component and a horizontal component, the vertical component spanning a vertical distance between the outer absorbent member and the central absorbent member, and the horizontal component spanning a horizontal distance on the body side surface of the absorbent core,the absorbent article further comprising a topsheet, wherein the topsheet is provided with at least one fold to form an elevated runoff barrier.

Abstract
An absorbent article comprising a central absorbent member and a lateral wicking barrier for inhibition of wicking from the central regions of the article to an outlying outer absorbent member. The wicking barrier has a vertical component for prevention of radial wicking in the plane of the article and thus promotes center filling of the article with fluid and reduces the likelihood of leaks from the sides of the article. The wicking barrier can also have a horizontal component to prevent leakage, redirect fluid flow, and improve fit and performance of the article. In one embodiment, the central absorbent member is a concentric absorbent structure having alternating rings of barrier material and absorbent material, including a spiral wound composite formed from a layer of barrier material wound with a layer of absorbent material and then sliced.
