In this manual, the face that " skin face " refers to when the wearing of dressing with article 1 and the skin of wearer is faced, " non-skin face " refers to the face opposite with described skin face.

Next, major part of the present invention is described.

In Fig. 1, described outer package non-woven fabrics 4 comprises along described waistline direction and is divided into two-part a pair of non-woven fabrics 4A, the 4A cut apart.Described a pair of non-woven fabrics 4A, the 4A respectively cut apart possesses respectively protuberance 42, the non-protuberance 40 of front portion and the non-protuberance 41 at back (rear portion).

Described each

protuberance

42,42 can be close to each other as Fig. 3 and Fig. 7 A at crotch 22 places, also can be as Fig. 7 C a part overlapped, can also be as Fig. 7 B line 42e, the 42e of the edge of protuberance 42 overlapped.That is, as long as line 42e, the 42e of each

protuberance

42,42 edge are parallel to each other and approach or overlapping.

Line 42e, the 42e of the edge of described protuberance is parallel or overlapping each other.On the other hand, line 40e, the 40e of the edge of the non-protuberance of the described front portion that is separated from each other almost parallel each other.And line 41e, the 41e of the edge of the non-protuberance at rear portion be also mutual almost parallel each other.

The non-protuberance 40,40 of the front portion of Fig. 1 is separated from each other in the front portion of described waist each other than described

protuberance

42,42 the larger distance of distance.And the non-protuberance 41,41 at back is separated from each other at the back of described waist each other than described

protuberance

42,42 the larger distance of distance.

At described front portion and back, reach the position of the tergite 27 between 41,41 and the non-protuberance 40,41 of described front and back between described each non-protuberance 40,40 and covered by described waistline

non-woven fabrics

30,31.

As Fig. 3 expressed, the tergite 27 of described absorbent main body 2 was not being covered by described outer package non-woven fabrics 4 between the described

non-protuberance

40,40 and between the non-protuberance 41,41, and is covered by described waistline non-woven fabrics 30,31.Therefore, wearer is difficult for feeling and hardens between described non-protuberance.

On the other hand, part or all that is applied to described style, figure and/or literal on the described resin sheet 27 covered by described front waistline member 3F or rear waistline member 3B, but covered by described outer package non-woven fabrics 4.Therefore, the easy visuognosis style etc. of the third party (beholder).

On the other hand, as Fig. 3 expressed, the tergite 27 of absorbent main body 2 was at described

protuberance

42,42 places, and namely between

waistline member

3F, 3B, roughly whole zone is covered by outer package non-woven fabrics 4.Therefore, tergite 27 can expose to the surface in fact hardly.Outward appearance and the feel of therefore, dressing with article 1 improve.

Described a pair of described each protuberance 42 of cutting apart

non-woven fabrics

4A, 4A is mutually the same from described each non-protuberance 40,41 outstanding overhang H, H.In the situation that the present embodiment, as shown in Figure 3, describedly a pair ofly respectively cut apart

non-woven fabrics

4A, 4A mutually each other roughly the same shape, size and structure, and be configured to each other the line symmetry.

Anterior non-protuberance 40 equals three length L 3 of described each protuberance 42 on described vertical Y in the first length L 1 on described vertical Y and the non-protuberance 41 at described back in the second length L 2 sums on described vertical Y.Relation by being set as this length L 1～L3 and the relation of described overhang H, H can be from a pair of non-woven fabrics 4A, the 4A cut apart of the lavishly generation that a long continuous non-woven fabrics does not have material.

Need to prove, the first length L 1 to the second length L 2 is little, but also can be mutually the same, otherwise or L1 larger than L2.

In the situation that the present embodiment, tergite 27 and the equal in length of outer package non-woven fabrics 4 on vertical Y, and the position consistency of the end on vertical Y of tergite 27 and outer package non-woven fabrics 4.And the distance D 1 between the described length L of protuberance 42 3 preferred and described front waistline member 3F and the rear waistline member 3B is same degree.

Yet, can be that the length L 3 of protuberance 42 is grown than described distance D 1, the part of protuberance 42 and front waistline member 3F or rear waistline member 3B overlap joint.And, also can be that the length L 3 of protuberance 42 is less than described distance D 1, and the part of tergite 27 be exposed between front waistline member 3F and rear waistline member 3B.

Shown in Fig. 2 A and Fig. 2 B, respectively cut apart on the non-woven fabrics 4A described, in the other edge of described protuberance 42 be outer package non-woven fabrics 4 edge, the outside near the elastic component F2 that lower limb is used also can be set.Need to prove, on described

non-protuberance

40,41 position, also described elastic component F2 can be set, or elastic component F2 is carried out ineffective treatment.And, also can be turned back and form three-dimensional rivel to the top flat side of absorbent main body in the edge, the outside that disposes elastic component F2, omit thus cut channel 25.

Next, with reference to Fig. 4～Fig. 6 this wearing manufacture method of article 1 is described.

As shown in Figure 4, form continuous non-woven fabrics W4 that the outer package of described outer package non-woven fabrics 4 uses by alongst Y1 carrying.This continuous non-woven fabrics W4 when alongst Y1 is handled upside down the cut-out line CL along square waveform this non-woven fabrics W4 is cut.Thus, described continuous non-woven fabrics W4 is divided into the first successive segmentation non-woven fabrics W41 with the first protuberance 421 and first recess 401 and has the second recess 402 and the second successive segmentation non-woven fabrics W42 of the second protuberance 422.

Next, in the mode that the width X with described length direction Y1 quadrature is separated from each other, described two successive segmentation non-woven fabrics W41, W42 are relatively moved with described the first successive segmentation non-woven fabrics W41 and the second successive segmentation non-woven fabrics W42 along described width X.

Then, with described the first protuberance 421 and described the second protuberance 422 mutual opposed and described the first recesses 401 and described the second recess 402 mutual opposed modes, change described the first successive segmentation non-woven fabrics W41 and the configuration relation of the second successive segmentation non-woven fabrics W42 on length direction Y1.That is, a pair of successive segmentation non-woven fabrics W41, W42 relatively alongst Y1 move half-wavelength or (n+1/2) wavelength (n is natural number), both concavo-convex phase places are consistent with each other.

In described phase place after changing, or when changing described phase place, as shown in Figure 5, in the overlapped mode of the first protuberance 421 and the second protuberance 422 line 42e close to each other or edge, change described the first successive segmentation non-woven fabrics W41 and the configuration relation of the second successive segmentation non-woven fabrics W42 on width X.At this moment, when the described line 42e of two non-woven fabrics W41, W42 was mutually bonding or bonding and continuous each other or near it, the carrying of two non-woven fabrics W41, W42 became easy.

On the other hand, as shown in Figure 5, between the continuous resin sheet S27 that forms tergite and the continuous non-woven fabrics W26 that forms top flat, by off and on configuration and stacked absorbent core 24, and the continuum W28 of generation absorbent main body.And, with the alongst Y carrying of described non-woven fabrics W41 and the mutual almost parallel of W42 ground, and make simultaneously the continuum W28 of absorbent main body and described non-woven fabrics W41, W42 overlapping bonding and generate continuous duplexer W2.At described configuration relation after changing, configure the continuum W28 of described absorbent main body to stride described the first successive segmentation non-woven fabrics W41 and the second successive segmentation non-woven fabrics W42 and overlapping mode, thereby generate this continuous duplexer W2.

Need to prove, at this moment, the absorbent core of described continuum W28 24 and

protuberance

42,42 overlapped.

As shown in Figure 6, described continuous duplexer W2 downcuts into each along the cut-out line that is represented by double dot dash line and dresses the size (unit) of using article, generates the independent duplexer 2A that is made of the absorbent main body 2 that is laminated with outer package non-woven fabrics 4.90 ° of the independent duplexer 2A convolutions that generates.

After described convolution, independent duplexer 2A is erected between duplexer W3F, the W3B as the continuous non-woven fabrics of a pair of waistline member 3F, 3B.Duplexer W3F, the W3B of described each continuous non-woven fabrics clip rubber covered wire etc. respectively between a pair of non-woven fabrics, and alongst are handled upside down with the state that is separated from each other the mutual almost parallel of X1.

After described setting up, described

waistline member

3F, 3B are being cut off along width Y between dressing with the mode of the length of article 1 independent duplexer 2A, 2A adjacent one another are to become each.Thus, can access each dresses with article 1.

Need to prove, also can be with the duplexer doubling under the continuum of states before downcutting into each wearing usefulness article 1.

Embodiment 2
