Problems solved by technology

[0008] However, in the above-mentioned absorbent article, since the means for fixing the absorbent article and the underwear is only the fixing sheet, and the area for fixing the absorbent article and the underwear is located on the side of the clothes-contacting surface with the crotch of the underwear, there is a possibility that the movement of the wearer may occur. The problem of absorbent articles floating from the crotch and detaching from the underwear when
[0009] In addition, since the above-mentioned absorbent article is rolled back to the crotch of the underwear, friction occurs between the root of the leg and the crotch when the wearer walks. discomfort

change example 1

[0091] refer to Figure 9 , the absorbent article 1 according to Modification 1 of the present invention will be described. Next, the absorbent article 1 according to Modified Example 1 will be described focusing on the differences from the absorbent article 1 according to the embodiment of the present invention.

[0092] Such as Figure 9 As shown, in the absorbent article 1 according to the modified example 1, on the back sheet 3 , overlapping regions where the pieces 3A to 3C of the sheet overlap are provided along the width direction of the absorbent article 1 .

[0093] In the absorbent article 1 according to Modified Example 1, it is preferable to form the application pattern of the adhesive agent 5 so that the force when the absorbent article 1 is peeled off from the underwear can be dispersed.

[0094] For example, it is preferable to make the application pattern of the adhesive 5, specifically, the pattern formed by the application area of ​​a plurality of adhesives...

[0096] refer to Figure 10 , the absorbent article 1 according to Modification 2 of the present invention will be described. Next, the absorbent article 1 according to Modification 2 will be described focusing on the points different from the absorbent article 1 according to the embodiment of the present invention.

[0097] Such as Figure 10 As shown, in the absorbent article 1 according to Modification 2, on the back sheet 3 , overlapping regions where the sheet segments 3A to 3D overlap are provided along both the width direction and the longitudinal direction of the absorbent article 1 . In addition, the fragments 3A to 3D of the sheet are shorter than the length of the back sheet 3 .

[0098] According to the absorbent article 1 of Modification 2, compared with the other embodiments in this specification, the vertical and horizontal lengths of the sheet segments 3A to 3D can be minimized, so that the dispersibility in water can be improved.

[0100] refer to Figure 11 , the absorbent article 1 according to Modification 3 of the present invention will be described. Next, the absorbent article 1 according to Modification 3 will be described focusing on the points different from the absorbent article 1 according to the embodiment of the present invention.

[0101] Such as Figure 11 As shown, in the absorbent article 1 according to Modification 3 of the present invention, on the back sheet 3, the overlap region where the sheet segments 3A to 3C overlap is along the oblique direction with respect to the longitudinal direction of the absorbent article 21 (for example, , 45° direction) setting. In addition, the fragments 3A to 3D of the sheet are shorter than the length of the back sheet 3 .

Abstract

Disclosed is an absorptive article (1) that comprises a hydrolytic surface sheet (2), a hydrolytic back sheet (3), and a hydrolytic absorber (4) provided between the surface sheet (2) and the back sheet (3). The back sheet (3) is configured of multiple sheet fragments (3A-3D), which are smaller than the main body of the absorptive article (1). The sheet fragments (3A-3D) are at least partially overlapped with each other. An adhesive (5) is applied to the overlap areas where the sheet fragments (3A-3D) are overlapped with each other.

Description

technical field [0001] The present invention relates to an absorbent article comprising a water-disintegratable top sheet, a water-disintegratable back sheet, and a water-disintegratable absorber disposed between the top sheet and the back sheet, and a method for manufacturing the absorbent article. Background technique [0002] Conventionally, as described in Patent Document 1, an absorbent article is known in which fixing sheets for fixing to underwear are formed so as to protrude to both sides of the main body. [0003] When wearing such an absorbent article, the wearer rolls the fixing sheet back on the crotch of the underwear to fix the absorbent article to the underwear. [0004] In such an absorbent article, a fragile portion that is easily torn is provided on a part of the fixing sheet so that the absorbent article can be easily removed from the underwear after use. In addition, such an absorbent article is formed of a water-disintegrable material in order to increa...
