This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,397.

Summary of the Inventive Concept

An absorbent article with advanced conforming features that provide enhanced fit, comfort, and performance, addressing the limitations of existing absorbent articles.

Background and Problem Solved

The original patent, 'Absorbent article with conforming features,' provided a fundamental design for absorbent articles. However, it had limitations in terms of fluid wicking, stiffness, and wet recovery energy. The new inventive concept addresses these limitations by introducing enhanced fluid wicking properties, hydrophilic coatings, breathable layers, and improved molding techniques, resulting in improved fit, comfort, and performance.

Detailed Description of the Inventive Concept

The new inventive concept comprises a topsheet with enhanced fluid wicking properties, a backsheet, an absorbent core with a plurality of absorbent fibers, and a first plurality of conforming features that provide improved fit and comfort to the wearer. The conforming features are created using a pressure-sensitive adhesive and molding techniques. The absorbent core may be unitary airlaid, comprising cellulosic fibers and super absorbent particles. The inventive concept also includes a method for creating conforming features, a system for manufacturing absorbent articles, and various alternative embodiments.

Novelty and Inventive Step

The new claims introduce several novel features, including enhanced fluid wicking properties, hydrophilic coatings, breathable layers, and improved molding techniques, which are not present in the original patent. These features provide a significant improvement in fit, comfort, and performance, making the new inventive concept non-obvious and novel compared to the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include variations in the topsheet material, absorbent core composition, and molding techniques. For example, the topsheet may be made of a different material, such as a natural fiber or a synthetic material, or the absorbent core may be composed of different types of fibers or particles. Additionally, the molding techniques may be modified to create different conforming feature shapes or sizes.

Potential Commercial Applications and Market

The enhanced absorbent article with conforming features has significant commercial potential in the hygiene and healthcare industries, particularly in the markets for diapers, training pants, feminine pads, and adult incontinence pads. The improved fit, comfort, and performance of the inventive concept make it an attractive solution for consumers and manufacturers alike.
