AI Technical Summary

Technical Problem

In the natural length state, the two corners on the waist opening side of the absorber selectively shrink in the width direction, resulting in the product being not compact when packaged or carried, and it is prone to wrinkles or cracks, affecting the absorption performance and wearing feeling.

Method used

By providing a continuous groove pattern in the edge area of ​​the absorber, the groove is recessed from the front face of the absorber into the absorber and has a bottom compressed in the thickness direction. As the center of the width direction of the absorber is leaned towards both side edges of the absorber, the area ratio and thickness of the bottom of the groove are changed phased or continuously to improve the shape maintenance of the edge area.

Benefits of technology

The shape maintenance of the waist-open side end of the absorber is improved, deformation caused by the elastic member is suppressed, and the flexibility of the absorber is maintained without affecting liquid diffusion and absorption performance.

Abstract

The purpose of the present invention is to suppress deformation caused by an elastic member at the waist-opening-side end of an absorber. The problem is solved by the following: an absorbent body (56) has an edge region (56E) including an edge on the waist opening (WO) side and an entirety in the width direction (WD) of a portion adjacent to the edge on the crotch section (M) side, the entirety of the edge region (56E) being positioned in a fixing region (201) of an interior body (200) and being fixed to exterior bodies (12F, 12B); grooves (53) are provided in a continuous pattern in the width direction (WD) over the entire edge region (56E) in the width direction (WD), the grooves (53) being recessed from the front surface of the absorber (56) into the absorber (56) and having a bottom section (51) compressed in the thickness direction, and the edge region (56E) extending from the center of the absorber (56) in the width direction (WD) toward both side edges of the absorber (56). The thickness of the bottom (51) of the groove (53) is constant and the area ratio of the bottom (51) of the groove (53) is increased.
