Absorbent article and process of producing the same

Abstract

The absorbent article has an outer sheet that provides an outer surface of the absorbent article, an inner sheet disposed on the inner side of the outer sheet, and elastic members for making below-waist gathers disposed between the two sheets. A patterned sheet is disposed between the outer and inner sheets such that the pattern of the patterned sheet may be seen through the outer sheet from the outside of the diaper. The elastic members for below-waist gathers each have a portion contributory to elastic extensibility and contractibility in the regions outside the lateral sides of the patterned sheet and a portion substantially non-contributory to elastic extensibility and contractibility in the region inside the lateral sides of the patterned sheet. The latter portion of the elastic member is disposed between the patterned sheet and the inner sheet and preferably is kept out of sight from the outside.

Description

technical field [0001] The present invention relates to a patterned absorbent product and its manufacturing method. Background technique [0002] Conventional underpants-type disposable diapers are known as absorbent products in which a plurality of elastic members are arranged in a peripheral direction on a waist portion worn on the wearer's waist to form waist gathers. In recent years, there have been proposals to cut off the elastic members for forming such waist gathers, which are arranged on the ventral side of the wearer's abdomen and / or near the center in the width direction of the dorsal part arranged on the back side. Waist gathers are formed on both sides in the width direction of the diaper. [0003] For example, the disposable diaper described in Japanese Unexamined Publication No. 2001-478 is equipped with a pleat laminate in which elastic members for forming waist gathers are disposed between two nonwoven fabric sheets. In other parts than the central part in...

AI Technical Summary

Problems solved by technology

[0006] In the diaper described in JP-A-2001-478, a total of three pieces of material are used to cover the outer side of the cut part of the elastic member, and it is not possible to manufacture a plurality of constituent parts at a lower cost.

[0007] The disadvantage of the diaper described in JP-A-2002-272783 is that the pattern cannot be clearly seen from the outside because it is covered by two non-woven fabrics

[0008] Although Japanese Patent Laid-Open No. 2001-61890 proposes that when the cut end of the elastic member of the waist portion is conspicuous, a concealing member for concealing it is arranged on the outer surface side of the elastic member of the waist portion, but no specific method is proposed.
