ABSORBENT ARTICLE WITH EXTENSIBLE EARS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18670169 titled 'ABSORBENT ARTICLE WITH EXTENSIBLE EARS

The patent application describes an absorbent article with specific features in the back waist region for improved performance.

The article has a liquid pervious topsheet, a liquid impervious backsheet, and an absorbent core.
It includes first and second back ears with specific engineering strain and roughness characteristics.
The first and second back ears have an engineering strain greater than about 8% at or below 2N of force.
The roughness Ra of the back ears is lower than about 300 μm.
These features are measured according to the Back Ear Extension Test and the Roughness Test.

Potential Applications: - This technology can be used in the manufacturing of absorbent articles such as diapers, sanitary napkins, and adult incontinence products.

Problems Solved: - The specific design of the back ears helps improve the fit, comfort, and overall performance of the absorbent article.

Benefits: - Enhanced comfort and fit for users. - Improved leakage protection. - Better overall performance of the absorbent article.

Commercial Applications: - This technology can be valuable for companies producing absorbent articles for various age groups and demographics.

Questions about the Technology: 1. How does the engineering strain of the back ears impact the overall performance of the absorbent article? 2. What are the implications of the specific roughness characteristics of the back ears on user experience and comfort?

Original Abstract Submitted

An absorbent article has a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and backsheet; first and second opposing longitudinal side edges, a front waist region and a back waist region; and a first and second back ear extending outwardly from the first and longitudinal side edges in the back waist region, respectively. The first and second back ears have an engineering strain greater than about 8% at about or below 2N of force when measured according to the Back Ear Extension Test, and a roughness Ra lower than about 300 μm when measured according to the Roughness Test.
