example 1-3

[0169] Examples 1 to 3 are generally based on Figure 12A and 12B were carried out, and unless otherwise noted the materials described in Table 1 were used.

[0170] In Example 1, the central absorbent member comprised a layer of 250 gsm dense airlaid web with a density of 0.14 g / cc. The outer absorbent member was a dense airlaid web with a basis weight of 175 gsm and a density of 0.1 g / cc.

[0171] A central longitudinal slit of length 100 mm was manually cut in the central absorbent member with a rotary knife.

[0172] The central raised member 30 below the central absorbent member 18 may be a section of a dense airlaid web having a basis weight of 175 gsm, and a density of 0.1 g / cc, cut to dimensions of 110 mm by 70 mm, and folded into two crease lines perpendicular to the machine direction and evenly spaced to form an "e" folded web having a width of approximately 40 mm and a length of 70 mm. The crease lines defining the folds are oriented in the longitudinal directio...

example 4

[0180] Example 4 is a hypothetical example according to Example 1, except that Figure 12B In the upper layer 50, leaving the "e" folded absorbent central projection member 30 as the main element of the central absorbent member 18, as Figure 13 shown. Thus, the central absorbent member 18 includes the absorbent central projecting member 30 and, in fact, substantially includes the absorbent central projecting member 30 .

Abstract

An absorbent article is disclosed comprising a central absorbent member, an outer absorbent member, and a central rising member for urging the central absorbent member toward the body of the user when compressed laterally inward by the legs of the user. The article is able to achieve good center-fill performance when in use and maintain excellent body fit.

Description

technical background [0001] In order to prevent body exudates from escaping from absorbent articles such as feminine care pads or sanitary napkins and disposable diapers, it is desirable that the exudates not reach the edges of the absorbent material in the article. A "fill-in-the-middle" strategy is ideal for leak control, where fluid is preferably retained within the central region of the article. Unfortunately, in conventional absorbent articles, there is generally no impediment to bulk flow or capillary wicking from the target area to the edges of the article, so leakage from the edges of the article is always a problem. Thus, in conventional articles, fluid entering the center of the article still has the potential to travel to the sides and leak. When the product is compressed, the wetted central portion of the product comes into contact with the absorbent material on the sides of the product, whereby fluid flows particularly rapidly from the center to the sides. ...
