AI Technical Summary

Technical Problem

Absorbent articles with through-holes and welded parts for securing a leakproof sheet risk misleading users into thinking excrement will leak from the welded parts, compromising absorbency and leakage prevention.

Method used

An absorbent article design with a skin-side sheet having openings and a space-forming sheet portion that is stretchable and welded to overlap areas larger than the openings, reducing the visibility of welded parts and enhancing absorbency while preventing leakage.

Benefits of technology

Improves absorbency and reduces the likelihood of users mistaking welded parts for leakage points, ensuring effective excrement containment.

Abstract

To reduce the possibility of misunderstanding that excrement leaks from a weld part for fixing a space forming sheet part while improving the absorbency of the excrement.SOLUTION: There is provided an absorbent article provided with a skin side sheet part provided closer to a skin side than an absorber and having an opening. The skin side sheet part has at least a portion provided in a central part in a width direction and capable of abutting on the skin when worn, and has a space forming sheet part for forming an excrement storage space provided in a back side end part in a longitudinal direction closer to the skin side than the skin side sheet part. The sheet part is stretchable in the width direction. Both side parts in the width direction of the sheet part are joined to a member overlapping with the sheet part in a thickness direction by a plurality of weld parts. An end part on the back side of the sheet part is fixed to at least a member adjacent to the sheet part in the thickness direction. An end part on an abdominal side in the longitudinal direction of the sheet part can form an entrance to the excrement storage space. An average area of the weld parts is larger than an average area of openings in an exposed region exposed to the skin side of the skin side sheet part.SELECTED DRAWING: Figure 5
