When such wire groove is formed at the skin opposite face of sanitary towel 1, can the diffusion of the liquid of the in-plane of decrease uptake body 4 effectively, and wrinkling of absorber 4 can be prevented.The formation of wire groove is for preventing the diffusion of the discharged liquid such as menses and promoting when wearing the close property of health etc. especially effective.Particularly, effectively can prevent wrinkling of rear quadrate part C and spilling of rear adipping by the pod 51 of rear quadrate part C, inner side slot 61 when wearing sanitary towel 1 along the ditch of the buttocks of wearer, therefore, it is possible to effectively prevent rear leakage.The wire groove that the width (length in direction orthogonal to the longitudinal direction) of wire groove and the degree of depth are planted in absorbent commodity therewith sets equally.

As shown in Figure 1, pod 51 across by absorbent main body 5 in the lateral direction y binary centrage (not shown) be formed with a pair, this pair pod 51,51 is formed as symmetrical with this centrage for benchmark.A pair pod 51,51 is not only distinguished portion C in the wings and is extended, and also extends at excretory portion counterpart B and front part A respectively, in excretory portion counterpart B, extends in the outside of the horizontal Y of multi-layer portion 42 on longitudinal X.

In the present embodiment, as shown in Figure 1, as above-mentioned wire groove, except the groove 51,61 extended on longitudinal X, the translot 71,72 extended in the lateral direction y is also sequentially formed from the front side of longitudinal X of absorbent main body 5 to rear side.Translot 71 is positioned at front part A, and when overlooking to the front end convex curvature of longitudinal X of absorbent main body 5, in addition, translot 72 is positioned at rear quadrate part C, and when overlooking to the rear end convex curvature of longitudinal X of absorbent main body 5, two grooves 71,72 only its protrude towards different and plan view shape is identical.The top of translot 71,72 respective protrusions is positioned at the central authorities of the horizontal Y of absorbent main body 5.A pair pod 51,51 and translot 71,72 link in the end of their length direction, thus, the skin opposite face of absorbent main body 5 be formed overlook time (roughly oblong shape) in the form of a ring groove.

Inner side slot 61 is in the top view shown in Fig. 1, and be formed as the roughly U-shaped protruded to the rear end of longitudinal X of absorbent main body 5, the top of this protrusion becomes the rear end 61b of longitudinal X.The rear end 61b (top of the protrusion of U-shaped) of the inner side slot 61 of U-shaped is positioned at the substantial middle of longitudinal X of rear alar part 8.In addition, front end 61a, 61a of longitudinal X of the inner side slot 61 of U-shaped be positioned at the boundary 15 of excretory portion counterpart B and rear quadrate part C or its near, thus, inner side slot 61 is utilized effectively can to prevent the diffusion of the in-plane of the discharged liquid such as the menses spilt from excretory portion counterpart B.The boundary 15 of excretory portion counterpart B and rear quadrate part C, consistent with " linking the straight line of root of rear side of a pair tab portion 7,7 respective longitudinal X " or " by the rear end of longitudinal X of multi-layer portion 42 transversely the straight line that extends of Y ", the position also residing for longitudinal front end 8a of rear alar part 8.The part that extends longitudinally in the inner side slot 61 of U-shaped (rear end 61b and near it beyond part), being positioned at than the mode of rear end by the outside of horizontal Y with the front end 61a of its longitudinal X when overlooking, tilting relative to longitudinal X.

In figure 3, the major part of the skin opposite face of positive dough sheet 2 is amplified expression.At the skin opposite face 2a (the skin opposite face of sanitary towel 1) of positive dough sheet 2, in the direction (i.e. incline direction) intersected respectively with longitudinal X and horizontal Y, the upper depressed part 20 extended is formed as oblique clathrate, utilize depressed part 20 that positive dough sheet 2 is divided into multiple region, and be formed with multiple zoning 22.In the embodiment shown in Fig. 3, depressed part 20 is formed throughout the whole region of positive dough sheet 20.Also can replace this structure, at least form depressed part 20 at excretory portion counterpart B.In addition, the X-direction in Fig. 3 is the direction identical with the direction (CD) of the flow direction of the sheet material be orthogonal to when positive dough sheet manufactures, and is the direction identical with longitudinal X of sanitary towel 1 (with reference to Fig. 1).In addition, the Y-direction in Fig. 3 is the direction that the flow direction (MD) of sheet material when manufacturing with positive dough sheet is identical, and is the direction identical with the horizontal Y of sanitary towel 1 (with reference to Fig. 1).

Align dough sheet 2 to be further described, positive dough sheet 2 such as comprises the fibre sheet materials such as the non-woven fabrics of monolayer constructions will or multi-ply construction, the whole region of its skin opposite face 2a has concaveconvex shape as shown in Figure 3, and this concaveconvex shape has multiple protuberance 21 being formed as oblique cancellate depressed part 20 and being surrounded by this depressed part 20 respectively.On the other hand, the non-skin opposite face 2b of positive dough sheet 2 does not have concaveconvex shape in fact, is formed as general planar.

Depressed part 20 is by the formation fiber crimping of the positive dough sheet 2 by comprising fibre sheet material or bonding and formed.Method as crimping fiber can be enumerated with heat or not with the embossing processing etc. such as extrusion process, ultrasound wave extrusion process of heat.Consequently, in positive dough sheet 2, the density of depressed part 20 becomes higher than the density of protuberance 21.Thus, when aligning dough sheet 2 and being applied with external force, depressed part 20 easily plays a role as the flexible axle of distortion.The depressed part 20 of the positive dough sheet 2 of present embodiment is formed by implementing the processing of hot pressing stricture of vagina to the fiber mesh cloth formed by comb and parallel cotton fibers prior to spinning method.In depressed part 20, positive dough sheet 2 or fusing property of the formation fiber instant heating fiber of non-woven fabrics forming this positive dough sheet 2 are fused by heat and integrated.The heat of fusing property of the heat fiber in depressed part 20 fuses components fuse and does not maintain the form of fiber.

In positive dough sheet 2, depressed part 20 is only formed in positive dough sheet 2, is not formed in positive dough sheet 2 with this and adjoins and be configured in the absorber 4 of the below of this positive dough sheet 2.Therefore, positive dough sheet 2 does not engage via depressed part 20 with absorber 4.

Depressed part 20 is preferably wire.The shape that so-called " wire " is not limited to depressed part 20 is herein the straight line shown in Fig. 3 when overlooking, also curve is comprised, and each line can be continuous lines, or also can be that multiple recesses (embossing portion) not spaced apart and connected in fact the making of rectangle, square, rhombus, circle, cross etc. is formed as continuous lines as a whole when overlooking." not spaced apart in fact " refers to that the adjacent spaces of recess is within 5mm.

Depressed part 20 is formed as oblique clathrate as shown in Figure 3.More specifically, positive dough sheet 2, have as depressed part 20 and be parallel to each other and the depressed part 20a of multiple first wire formed at predetermined intervals, with be parallel to each other and the depressed part 20b of multiple second wire formed at predetermined intervals, the depressed part 20a of the first wire and the depressed part 20b of the second wire form the angle that specifies and mutually intersect.The depressed part 20a of the first wire and the depressed part 20b of the second wire all linearly extends on the direction (i.e. incline direction) intersected with longitudinal X and horizontal Y respectively.The width of the depressed part 20a of the first wire can be identical with the width of the depressed part 20b of the second wire, or also can be different.The depressed part 20b interval each other of the depressed part 20a of the first wire interval each other and the second wire can be identical, or also can be different.

Each zoning 22 is the regions around surrounded by the depressed part 20 of wire respectively, is diamond shape when overlooking.The area of each zoning 22 is such as preferably 0.25cm ²above 2cm ²below.Zoning 22 can be formed as when overlooking compared with longitudinal X, diamond shape longer in the lateral direction y.Or, also in contrast, diamond shape longer on longitudinal X compared with horizontal Y can be formed as.When being formed as shape longer on the horizontal Y of sanitary towel 1 in zoning 22, the positive dough sheet 2 being formed with multiple depressed part 20 keeps higher rigidity at horizontal Y, can effectively prevent thus in the wearing effect of sanitary towel 1 wrinkle or wrinkling.In the wearing effect of sanitary towel 1 wrinkle or wrinkling mainly due to be clipped in wearer two huckles between sanitary towel 1 extruded from horizontal Y by this huckle, when positive dough sheet 2 keeps higher rigidity at horizontal Y, even if be extruded the shape that also easily can maintain sanitary towel 1 from horizontal Y, not easily to wrinkle or wrinkling.

Be formed with the protuberance 21 relative to the depressed part 20 relative property lifting surrounding this zoning 22 in each zoning 22, each zoning 22 is formed as the convex form in skin opposite face 2a side with top 21a.The top 21a of protuberance 21 is positioned at the central part of zoning 22.Filled up by the fiber 25 that forms of positive dough sheet 2 in protuberance 21.As described below, do not get rid of the form of the depressed part beyond wire in the present invention, but from forming the viewpoint of good protuberance 21, depressed part is preferably wire.

Like this, depressed part 20 and protuberance 21 alternately configure respectively on longitudinal X and horizontal Y of positive dough sheet 2, thereby, it is possible to reduce the contact area of the skin of sanitary towel 1 and wearer, and effectively prevent sultry or macule.In addition, protuberance 21 (zoning 22) is surrounded by depressed part 20, and be closed shape when overlooking, thus, can't help compared with situation that depressed part 20 surrounds with protuberance 21, the formation fiber in protuberance 21 easily extends to the thickness direction of positive dough sheet 2, therefore the thickness of protuberance 21 increases, play following etc. effect thus: 1) liquid promptly through, and liquid residue is less, and positive dough sheet 2 reduces with the contact area of skin; 2) protuberance 21 is formed by the pattern of rule, and therefore eye impression is good.

Figure 4 illustrates the major part of absorber 4.As shown in Figure 4, absorber 4 is formed with the excretory portion gap zone S of longitudinal slot 43 of multiple X along the longitudinal in the state that excretory portion counterpart B has to disperse.Longitudinal slot 43 is formed among the multi-layer portion 42 in excretory portion counterpart B and both the positions beyond multi-layer portion 42.

Each longitudinal slot 43 is independent separately, and non-slot portion 43' is positioned at adjacent longitudinal slot 43 each other.And the whole region of the surrounding of each longitudinal slot 43 is surrounded by non-slot portion 43'.
