AI Technical Summary

Technical Problem

Existing absorbent materials experience a decrease in the bulge of the central pleats during wear due to activity or changes in posture. This reduces the fit relative to the excretion opening and increases the risk of bodily fluid leakage, especially when large amounts of bodily fluid are expelled.

Method used

A central pleat is provided in the central area of ​​the absorbent article. The central pleat is connected to the top sheet and absorbent body through a central telescopic member. It ensures that the top sheet bulges towards the skin and supports and stabilizes the bulge in the width direction through a pair of separate joints, thereby enhancing the fit.

Benefits of technology

It improves the fit of absorbent materials to the discharge port, reduces bodily fluid leakage, and effectively introduces and inhibits leakage, especially when large amounts of bodily fluid are discharged, while maintaining a stable fit in different postures.

Abstract

An absorbent article is provided that can further improve the fit relative to the excretion opening by utilizing a central pleat. The absorbent article (1) comprises: an absorbent body (30) having absorbent material; a top sheet (21) disposed in a central region (R10) of the width center (1CW) of the absorbent article, which abuts against the wearer's skin; and a central pleat (40) disposed between the top sheet and the absorbent body, which raises the top sheet toward the skin side (T1) in the central region. The central pleat has a central telescopic member (42) that extends at least in the front-back direction. The central pleat is engaged with the top sheet at a pair of first joints (45) on both sides relative to the width center of the article, and engaged with the absorbent body at a pair of second joints (46) on both sides relative to the width center of the article.
