Description

本発明の特徴は、前胴回り域（前胴回り域20）、後胴回り域（後胴回り域30）及び股下域（股下域25）とから構成され、液保持性の吸収体を含む縦長の吸収体（吸収体40）と、前記吸収体の幅方向における側縁部の少なくとも一部に設けられるサイドフラップ（サイドフラップ70）と、前記サイドフラップに取り付けられ、前記前胴回り域または前記後胴回り域の一方から前記吸収体の製品幅方向（製品幅方向W）外側に延出し、前記前胴回り域または前記後胴回り域の他方に止着されるように構成された一対のファスニングテープ（ファスニングテープ90）とを備える使い捨ておむつ（使い捨ておむつ10）であって、前記ファスニングテープは、前記サイドフラップから延在する基材シート（基材シート91）と、前記基材シートの肌当接面の一部に備えられ、複数の係合フックが設けられたフックシート（フックシート92）とを含み、前記フックシートは、前記基材シートの製品幅方向外側の端部まで備えられ、前記フックシートが存在するフックシート存在域（フックシート存在域S_HS）における前記ファスニングテープの製品幅方向における単位長さ当たりのKES曲げ剛性値は、0.015974N f/cm²/cm以下であることを要旨とする。 A feature of the present invention is that it is composed of a front waistline region (front waistline region 20), a rear waistline region (rear waistline region 30), and a crotch region (inseam region 25), and a vertically long absorbent body including a liquid retaining absorbent body. (Absorber 40), a side flap (side flap 70) provided on at least a part of a side edge in the width direction of the absorber, and attached to the side flap, the front waistline region or the rear waistline region A pair of fastening tapes (fastening tape 90) configured to extend from one side to the outside in the product width direction (product width direction W) of the absorber and to be fixed to the other of the front waistline region or the rear waistline region A disposable diaper (disposable diaper 10), wherein the fastening tape is a base sheet (base sheet 91) extending from the side flap, and a part of the skin contact surface of the base sheet A hook sheet (hook sheet 92) provided with a plurality of engagement hooks, the hook sheet being provided up to the end of the base sheet in the product width direction, wherein the hook sheet exists. The gist is that the KES bending stiffness value per unit length in the product width direction of the fastening tape in the hook sheet existing area (hook sheet existing area S _HS ) is 0.015974 Nf / cm ² / cm or less.

（１）使い捨ておむつの全体概略構成
図１は、本実施形態に係る使い捨ておむつ10の展開平面図である。図２は、図１に示したF1-F1線に沿った使い捨ておむつ10の断面図である。図３は、図１に示したF2-F2線に沿った使い捨ておむつ10の断面図である。図１に示す展開平面図は、使い捨ておむつを構成するトップシート50、サイドフラップ70等の皺が形成されない状態まで、レッグ伸縮部75及びレッグサイドギャザー80の弾性部材71を伸長させた状態の図である。 (1) Overall Schematic Configuration of Disposable Diaper FIG. 1 is a developed plan view of a disposable diaper 10 according to this embodiment. FIG. 2 is a cross-sectional view of the disposable diaper 10 taken along line F1-F1 shown in FIG. FIG. 3 is a cross-sectional view of the disposable diaper 10 taken along the line F2-F2 shown in FIG. Developed plan view shown in FIG. 1, the topsheet 50 constituting the disposable diaper, to a state in which wrinkles such as side flaps 70 are not formed, the state of being stretched elastic member 71 of the leg stretch unit 75 and the leg side gathers 80 FIG.

また、フックシート92が存在するフックシート存在域S_HSにおけるファスニングテープ90の製品幅方向Wにおける単位長さ当たりのKES曲げ剛性値は、0.015974N /cm²/cm以下である。 In addition, the KES bending rigidity value per unit length in the product width direction W of the fastening tape 90 in the hook sheet existing area S _HS where the hook sheet 92 is present is 0.015974 N / cm ² / cm or less.

ここで、表１は、ファスニングテープ90の実施例及び比較例に係る基材シート91の構成及びKES曲げ剛性値の値を示す。

Here, Table 1 shows the configuration of the base sheet 91 and the KES bending stiffness value according to the examples and comparative examples of the fastening tape 90.

脚回り形成工程は、レッグ伸縮部75の幅方向外側端部に沿って、トップシート50、外装シート60、及びバックシート60aを切断する。これにより、着用者の脚回りに配置される脚回り開口部35が形成される。 In the leg periphery forming step, the top sheet 50 , the exterior sheet 60, and the back sheet 60a are cut along the outer end in the width direction of the leg stretchable part 75. Thereby, the leg opening part 35 arrange | positioned around a wearer's leg is formed.

（５）作用・効果
上述した使い捨ておむつ10によれば、複数の係合フックを有するフックシート92は、基材シート91の製品幅方向W外側の端部まで備えられる。また、フックシート92が存在するフックシート存在域S_HSにおけるファスニングテープ90の製品幅方向Wにおける単位長さ当たりのKES曲げ剛性値は、0.015974N /cm²/cm以下である。 (5) Action / Effect According to the disposable diaper 10 described above, the hook sheet 92 having a plurality of engagement hooks is provided to the end of the base sheet 91 outside the product width direction W. In addition, the KES bending rigidity value per unit length in the product width direction W of the fastening tape 90 in the hook sheet existing area S _HS where the hook sheet 92 is present is 0.015974 N / cm ² / cm or less.
