Absorbent Article With A Waistband And Leg Cuff Having Gathers

Abstract

A disposable absorbent article comprising a first waist region, a second waist region, a crotch region disposed between the first waist region and second waist region; a first waist edge and a second waist edge; and a first longitudinal edge and a second longitudinal edge; the disposable absorbent article comprising a waistband and a leg gasketing system, wherein the waistband has a first gather count and the leg gasketing system has a second gather count such that the ratio of the first gather count to the second gather count is from about 0.75 to about 1.25.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 499,298, filed Jun. 21, 2011, which is herein incorporated by reference in its entirety.FIELD OF INVENTION[0002]This invention relates to absorbent articles such as diapers having improved waistband properties that yield a more garment-like article. The absorbent article may have improved functional characteristics and communicative properties.BACKGROUND OF THE INVENTION[0003]Many diapers on the market today have waistbands or waist stretch elements in which a laminate of nonwovens and elastics strands are combined with the chassis under some tension. Elastic strands are the most cost effective way to get stretch that exhibits little relax or set over time. Nonwovens are preferred for the exterior of the waist material because it is breathable and softer than film alternatives. Some executions of applied waistband consist of elastics stretched in the process and app...

AI Technical Summary

Benefits of technology

[0080]One advantage of the leg gasketing system 70 of the present invention is that when a substantially liquid-impervious material is used in construction of the cuff, the polymeric film layer may be narrowed or not present at all, resulting in more cost effective designs. Utilizing adhesive technologies that are more reliably processed results in more reliable performance and creates substantially liquid impervious seals. This technology enables narrowing the film layer to be only slightly wider than the absorbent core by reducing the need for redundant seals. In one embodiment of the present invention, the backsheet polymeric film is less than about 50 mm wider than the absorbent core; optionally less than about 40 mm wider, less than about 30 mm wider. In one embodiment, the backsheet polymeric film is at lest about 20 mm more narrow than the chassis width; optionally at least about 40 mm more narrow than the chassis width; optionally at least about 60 mm more narrow than the chassis width; optionally at least about 80 mm more narrow than the chassis width; optionally at least about 100 mm more narrow than the chassis width; optionally at least about 120 mm more narrow than the chassis width.

Problems solved by technology

It is known that contraction around the waist will improve the perceived fit of the product by closing gaps at the back of the diaper, therefore, closing of these gaps could positively impact real or perceived leakage / containment.
