Description

Moreover, the intermediate | middle layer 12 is arrange | positioned inside the width direction W outer side edge part of side flap part SF. In order to prevent opening of the mouth, the round seal portion 10 is densely arranged at the outer end in the width direction W of the side flap portion SF. Therefore, the intermediate layer 12 is not disposed at the outer end portion in the width direction W of the side flap portion SF, whereby the outer end portion in the width direction W of the side flap portion SF is hardened by the round seal portion 10 and rubs the wearer. To prevent that.

FIG. 4 is a schematic cross-sectional view of an embossed portion in the absorbent article shown in FIG. The material constituting the intermediate layer 12 includes a material having a higher melting point than the material constituting the back sheet 3. When the intermediate layer 12 includes a material having a higher melting point than the back sheet 3, the embossed portion 20 can be formed by embossing at a temperature lower than the melting point of the intermediate layer. Therefore, damage to the back sheet 3 due to embossing from the side sheet 11 side can be suppressed, and defects such as pinholes can be prevented from occurring in the back sheet 3.

The area of the pattern embossed structure portion 92 is larger than the area of FIG shaped embossed structure portion 91. Therefore, pattern embossed structure portion 92, conspicuous than FIG shaped embossed structure portion 91 plays a role of a mark. For example, when the intermediate layer is configured to hold body fluid (for example, an air-through nonwoven fabric), when menstrual blood diffuses into the hip flap portion HF, the embossed wire draws menstrual blood and spreads. At that time, menstrual blood oozes into the pattern embossing component having a relatively large area, so that the user can visually recognize the pattern embossing component in which menstrual blood has oozed and judge the replacement time.

Further, the pattern embossed structure portion is preferably disposed to the rear than line of FIG shaped embossed structure portion. Pattern embossed structure portion, when placed behind the line of FIG shaped embossed structure portion, when the deformed hip flap portion from the wing portion positioned in front, deformation being transmitted toward the rear Can be suppressed.

(Modification 3)
Next, an absorbent article 1C according to Modification 3 will be described. FIG. 9 is a plan view of a part of the absorbent article according to Modification 1 as viewed from the surface side. Absorbent article 1C shown in FIG. 9, as the embossed portion has a second embossing lines 22 and the third emboss line 23. These embossed lines are constituted by a first embossing component 93 and a second embossing component 94, respectively.

The first embossing component 93 is an embossing portion that extends at least in the front-rear direction, and the second embossing configuration portion 94 is an embossing portion that is located on the inner side in the width direction than the first embossing configuration portion 93 and extends at least in the front-rear direction. is there. The 1st embossing structure part 93 and the 2nd embossing structure part 94 have overlapped in the width direction. In addition, the state where the 1st embossing structure part 93 and the 2nd embossing structure part 94 have overlapped in the width direction means a part of 1st embossing structure part 93 and the 2nd embossing structure part 94 on the straight line extended in the width direction. A part is in a position.

Since the first embossing component 93 and the second embossing component 94 overlap in the width direction, for example, when the intermediate layer has a configuration capable of holding body fluid (for example, an air-through nonwoven fabric), the absorbent article when the body fluid from the widthwise center in the width direction outer side flows, in each of the second embossing line 22, and the third emboss line 23 draws fluid in double, body fluid reaches the outer edge of the absorbent article Can be prevented.
