Embodiment 1

[0039] The present invention can be understood more clearly from the following description of preferred embodiments with reference to the accompanying drawings. However, the examples and drawings are for simple illustration and description, and are not used to determine the scope of the present invention. The scope of the present invention is determined only by the scope of the claims. In the drawings, the same part number in a plurality of drawings indicates the same or corresponding part.

[0040] Example 1

[0041] Hereinafter, the structure of the wearing article 1 of Example 1 of the present invention will be described with reference to the drawings.

[0042] Figure 1 to Figure 6 Example 1 is shown.

[0043] Such as figure 1 As shown in FIG. 2 , the wearing article 1 of the first embodiment includes an absorbent main body 2 , a front waist member 3F, and a rear waist member 3B. The absorbent main body 2 has a front part (front waist part) 20 covering the wearer's...

Embodiment 2

[0089] Figure 8 ~ Figure 13 Example 2 is shown. Hereinafter, regarding Example 2, differences from Example 1 will be mainly described.

[0090] exist figure 1 In the above-mentioned Example 1, the protrusions 42 of the divided nonwoven fabric 4A and the protrusions 42 are close to each other. Figure 8 In Example 2, the convex parts 42 of the divided nonwoven fabric 4A and the convex parts 42 are close to each other back to back, and the non-convex parts 40 of the front part of the divided nonwoven fabric 4A are close to each other, and the back of the divided nonwoven fabric 4A is close to each other. The non-convex portions 41 of the upper portion (back) are close to each other.

[0091] The pair of divided nonwoven fabrics 4A has a pair of first side edge portions 4e1 that approach or overlap each other from the front to the back. exist Figure 9A Among them, the convex portion 42 of the divided nonwoven fabric 4A has a second side edge portion 4e2 close to the pair o...

Abstract

Laminated on said absorbent body (2) is an outer nonwoven cloth (4) which covers the non-skin contacting surface of a back sheet (27) of an absorbent body (2). The outer nonwoven cloth (4) encompasses a pair of divided nonwoven cloths (4A, 4A) which are divided in the X direction, circumferential around the waist. The pair of divided nonwoven cloths (4A) is provided with a pair of convex parts (42) which are close to and overlap with one another at the crotch, front non-convex parts (40) which, located in front part of the torso, are further separated from one another than the pair of convex parts, and back non-convex parts (41) which, located in back part of the torso, are further separated from one another than the aforementioned pair of convex parts. In the front part and the back parts, the front and back non-convex parts (41) and the portion of the backsheet (27) between the aforementioned non-convex parts are covered by a nonwoven cloth which wraps around the torso.

Description

technical field [0001] The present invention relates to a disposable wearing article and its manufacturing method. Background technique [0002] Conventionally, in the process of manufacturing a diaper, a sheet is cut with a punching machine in order to form a leg hole through which a leg passes. With respect to this manufacturing method, since there is a need to reduce material waste and cost, an H-type manufacturing method in which leg holes are formed without cutting is known. [0003] In the H-type manufacturing method, an absorbent main body is bridged between a pair of waist members (Patent Document 1). [0004] In the H-shape manufacturing method, by forming the diaper into an H-shape, cutting of leg holes is not necessary. However, in the invention of Patent Document 1, the liquid-impermeable back sheet, that is, a resin sheet such as polyethylene, is exposed on the non-skin side of the crotch region, resulting in poor appearance and feel. [0005] Then, the diape...
