Benefits of technology

[0006]The present invention addresses one or more technical problems described above and provides a disposable absorbent article which may comprise a chassis and an absorbent core. The chassis may contain a topsheet and a backsheet. The absorbent core may be located between the topsheet and the backsheet and may include first and second absorbent layers. The first absorbent layer may include first substrate and the second absorbent layer may include a second substrate. The first and second absorbent layers may further include absorbent particulate polymer material deposited on the first and second substrates and thermoplastic adhesive material covering the absorbent particulate polymer material on the respective first and second substrates.

Problems solved by technology

Some technologies of immobilizing absorbent particulate polymer material in an absorbent article add bulk to the absorbent article and thereby increase thickness, reduce flexibility, and / or increase cost of the absorbent article.
Other technologies for immobilizing absorbent particulate polymer material in an absorbent article may not be as effective in maintaining immobilization when the absorbent article is in the wet state as when in the dry state.

Embodiment Construction

[0026]“Absorbent article” refers to devices that absorb and contain body exudates, and, more specifically, refers to devices that are placed against or in proximity to the body of the wearer to absorb and contain the various exudates discharged from the body. Absorbent articles may include diapers, training pants, adult incontinence undergarments, feminine hygiene products, breast pads, care mats, bibs, wound dressing products, and the like. As used herein, the term “body fluids” or “body exudates” includes, but is not limited to, urine, blood, vaginal discharges, breast milk, sweat and fecal matter.

[0027]“Absorbent core” means a structure typically disposed between a topsheet and backsheet of an absorbent article for absorbing and containing liquid received by the absorbent article and may comprise one or more substrates, absorbent polymer material disposed on the one or more substrates, and a thermoplastic composition on the absorbent particulate polymer material and at least a po...

Abstract

A disposable absorbent core comprises first and second absorbent layers each comprising an absorbent particulate polymer material such that the absorbent particulate polymer material is substantially continuously distributed across an absorbent particulate polymer material area. A disposable absorbent article and method for making the absorbent core are also disclosed.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of U.S. patent application Ser. No. 12 / 141,122, filed on Jun. 18, 2008 which claims the benefit of U.S. Provisional Application No. 60 / 936,102, filed on Jun. 18, 2007, which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention generally relates to an absorbent article, and more particularly to a disposable absorbent article with absorbent particulate polymer material, such as a diaper.BACKGROUND OF THE INVENTION[0003]Absorbent articles, such as disposable diapers, training pants, and adult incontinence undergarments, absorb and contain body exudates. They also are intended to prevent body exudates from soiling, wetting, or otherwise contaminating clothing or other articles, such as bedding, that come in contact with the wearer. A disposable absorbent article, such as a disposable diaper, may be worn for several hours in a dry state or in a urine loaded state. Accordingly, e...
