[0033] Figure 1-7 Representing the first embodiment of the invention of the present application, figure 1 It is a figure which shows the wearing state of the diaper 1. As shown, the diaper 1 includes an absorbent substrate 2 , a barrier sheet 3 and a leak-proof cuff 4 . The base 2 is formed in the shape of a pant, having a lateral X and a longitudinal direction Y, a body-side inner surface 5 and a garment-side outer surface 6, a front waist region 7, a rear waist region 8, and a lower portion located between the front and rear waist regions 7, 8. Crotch area 9. The base 2 is formed of an inner sheet 11 , an outer sheet 12 , and a liquid-impermeable leak-proof sheet 13 provided between the inner and outer sheets 11 , 12 .

[0034] In the front and rear waist regions 7 and 8 , the opposing surfaces of the waist side portions 14 and 15 overlap each other, and the plurality of joint portions 16 arranged intermittently are joined to each other to form a seam portion.

[0073] Figure 8 A second embodiment is shown. In this second embodiment, the form of the cutout portion formed in the barrier sheet 3 is different from that of the first embodiment, and the other components are the same as those of the first embodiment. Detailed descriptions of the same constituent elements are omitted.

[0074] In this embodiment, the barrier sheet 3 is provided with the cut-out part 57 which cut a part of both side parts 30 and 31. The cut-out portions 57 are formed by digging out the convex portions 39c and 40c of the first and second barrier sheet elastic members 39 and 40 and extending from the lateral X outer sides to the both sides 42 and 43 . In the cut-out portion 57, the both sides 42 and 43 are left without being cut, thereby forming a substantially triangular shape. By forming the cutout portion 57 in the barrier sheet 3 in this way, the area in which the barrier sheet 3 comes into contact with the wearer's skin can be reduced, and the wearer's...

[0078] Figure 9 , 10 A third embodiment is shown, which is characterized in that the barrier sheet 3 includes intermediate elastic members 58 on both side portions 30 and 31 . Components other than this feature are the same as those of the first embodiment. Detailed descriptions of the same constituent elements are omitted.

[0079] The intermediate elastic member 58 is attached to the outer side of the lateral direction X of the convex portions 39c and 40c of the intermediate portion 32 and the first and second barrier sheet elastic members 39 and 40 . The intermediate elastic member 58 extends outward in the lateral direction X from the vicinity of the convex portions 39c, 40c toward the side edges 42, 43, and is attached in an extended state. On the outer side of the lateral direction X to which the intermediate elastic member 58 is attached, the first fixing and attaching belt 51 is divided into two parts to form the first front and rear fixing and attaching belts 53 a...

Abstract

It is intended to provide an absorbent article by which stuffiness between a barrier sheet and the skin can be prevented and thus the wearer's skin can be prevented from a rash and so on. A diaper (1) which comprises a liquid-absorbing chassis (2), a barrier sheet (3) and leakage-blocking cuffs (4). The barrier sheet (3) has side sections (30, 31) facing to each other in the widthwise direction (X) and an intermediate section (32) connecting the side sections (30, 31). The intermediate section (32) is located below the crotch area (9). The side sections (30, 31) and the intermediate section (32) constitute together front-back connecting sections (33, 34). In the side sections (30, 31) located outside the intermediate section (32) along the widthwise direction (X), cuts (41) are formed. The cuts (41) are formed respectively by cutting the sheet from the outside in the widthwise direction (X) of the peaks (39c, 40c) in the elastic member of the barrier sheet toward the both side margins (42, 43) constituting the outer sides of the side sections (30, 31) along the widthwise direction (X) to form V-shapes.

Description

technical field [0001] The present invention relates to absorbent articles, and more particularly to absorbent articles such as disposable diapers, defecation training pants, incontinence tights, and the like. Background technique [0002] In the prior art, as a disposable diaper provided with a skin-contacting sheet without allowing excrement to come into contact with the wearer's skin, for example, Japanese Patent Laid-Open No. 2007-105298 (Patent Document 1) is known. According to this patent document 1, a diaper has a top sheet and a back sheet, an absorber disposed between the top sheet and the back sheet, a skin contact sheet disposed on the wearer's skin side of the top sheet, and the skin contact sheet is provided with a The object passes through the opening on the top sheet side and the elastic member attached in an extended state so as to surround the opening. Such a skin contact sheet is lifted from the top sheet by an elastic member, and is brought into contact ...
