===embodiment===

Fig. 1 is the diagrammatic perspective of the disposable diaper 1 (diaper 1) of one of the absorbent commodity as present embodiment Figure.Fig. 2 is the approximate vertical view of the diaper 1 of the deployed condition from skin side.Fig. 3 is the figure for the Section A-A for representing Fig. 2.

The diaper 1 of present embodiment is so-called 3 chip, has three parts 10,30,40.That is, in the diaper 1, as First component, there is the crotch part for being attached to wearer and absorb the absorbent main body 10 of the excretas such as urine, as second component, tool Have the veutro exterior member 30 of the veutro portion covering of the wearer, as third member, have the drosal part of the wearer The dorsal part exterior member 40 of covering.In addition, as shown in FIG. 2 and 3, the diaper 1 of deployed condition is with longitudinally, laterally and thick Direction is spent as three mutually orthogonal directions.In addition, " front side " of longitudinal direction is to cover the veutro of wearer when dressing diaper The part of lid, " rear side " are by the part of the dorsal part covering of wearer.In addition, the skin in a thickness direction with wearer is connect Tactile side is referred to as " skin side ", and its opposite side is referred to as into " non-skin side ".

Under Fig. 2 deployed condition, in veutro exterior member 30 (being longitudinal upside in figure) and dorsal part exterior member 40 (being longitudinal downside in figure) mutually it is arranged in parallel across compartment of terrain in the vertical in the state of, veutro exterior member 30 and the back of the body Have absorbent main body 10 between side exterior member 40, also, each end 10ea of the length direction of the absorbent main body 10, 10eb is engaged and is fixed on nearest exterior member 30,40 respectively, and its face shaping is in generally H shape when overlooking.Moreover, inhale The property received main body 10 carries out doubling from the state using the substantially central portion C10 of its length direction as folding position.When right at this Veutro exterior member 30 and dorsal part exterior member 40 under folding state opposite each other is in the portion that will be abutted with the flank of wearer Divide i.e. veutro exterior member side edge part 30se and dorsal part exterior member side edge part 40se (that is, horizontal each end) to be engaged, During link, these exterior members 30,40 are configured to annular each other.Thus, the formation turned into as shown in Figure 1 has waistline opening The diaper 1 of 1HB and a pair of leg circumference opening 1HL wearing state.

As shown in FIG. 2 and 3, absorbent main body 10 has：Absorbent core 11, the skin side covering absorption from the core 11 Property core 11 surface chip part 13, cover absorbent core 11 from the non-skin side of the core 11 and form the exterior of absorbent main body 10 The back side chip part 15 of part.

Absorbent core 11 is to be laminated the part that liquid-absorbent raw material forms, and is the absorber for absorbing the excretas such as urine.Make For liquid-absorbent raw material, it is, for example, possible to use the liquidabsorbing fibres such as paper pulp fiber.In addition, absorbent core 11 both can be with Contain such as superabsorbent polymer as liquid-absorbent shot-like particle, or, can also contain except liquidabsorbing fibres with And the liquid-absorbent raw material beyond liquid-absorbent shot-like particle.In addition, absorbent core 11 can also use the liquid-permeable sheets such as cotton paper Covering (not shown).Have between the longitudinal anterior end and rear end of the absorbent core 11 of present embodiment in fig. 2 The contraction flow region 11c of horizontal narrow width compared with anterior end and rear end.Thus, absorbent core 11 is configured to Fig. 2 institutes Show general hourglass shape during such overlook.

Surface chip part 13 is that e.g. planar dimension is than absorbing from the part of the sheet of skin side covering absorbent core 11 The non-woven fabrics of the property big liquid permeability of core 11.Back side chip part 15 is the part for the sheet that absorbent core 11 is covered from non-skin side, It is the planar dimension piece bigger than absorbent core 11, as one example, enumerates the leakage prevention sheet of the opaque liquids such as polyethylene or polypropylene The piece of two-layer structure obtained from the outer load 15b fittings such as 15a and non-woven fabrics.Moreover, absorbent core 11 is being clipped in these back ofs the body In the state of between dough sheet part 15 and surface chip part 13, in the part stretched out laterally from four sides of absorbent core 11, the back of the body 13 fitting in the shape of a frame of dough sheet part 15 and surface chip part, thus, form absorbent main body 10.In addition, back side chip part 15 Can not have outer load 15b and be only made up of leakage prevention sheet 15a.

In addition, in diaper 1, so-called three-dimensional rivel and calf circumference rivel can also be formed by outer load 15b etc. and (is not all schemed Show).The leakproof wall portion that three-dimensional rivel is e.g. erected and set in horizontal each end of surface chip part 13 respectively, calf circumference pleat Pleat is the calf circumference pars contractilis in each leg-openings 1HL, 1HL formation of diaper 1.Alternatively, it is also possible in surface chip part 13 and suction Receive property core 11 between or overleaf between chip part 15 and absorbent core 11 liquid-permeable sheet such as sandwiched cotton paper as second.

Veutro exterior member 30 and dorsal part exterior member 40 are all soft pieces such as using non-woven fabrics as raw material The chip part of shape in the form of a substantially rectangular during vertical view.As shown in figure 3, veutro exterior member 30 will by the skin side from thickness direction Skin lateral plate 31 and non-skin lateral plate 32 are engaged and formed in a manner of two overlapping.Similarly, dorsal part exterior member 40 from the skin side of thickness direction by skin lateral plate 41 and non-skin lateral plate 42 in a manner of two overlapping by being engaged And formed.Moreover, veutro exterior member 30 and dorsal part exterior member 40 cover from the non-skin side of absorbent main body 10 respectively Overlappingly engaged with above-mentioned each end 10ea, 10eb while longitudinal each end 10ea, 10eb of absorbent main body 10.

In veutro exterior member 30, the length of non-skin lateral plate 32 in the vertical is longer than skin lateral plate 31, in thickness side Upwards it is overlapping in the state of, longitudinal upper side end of non-skin lateral plate 32 is configured to stretch from longitudinal upper side end of skin lateral plate 31 Go out.Moreover, the extension of non-skin lateral plate 32 is turned back to the downside of longitudinal direction as shown in Figure 3, the part 32f and skin to be turned back Lateral plate 31 overlappingly engages.Thus, the quantity of the chip part of the end edge portion stacking on the upside of the longitudinal direction of veutro exterior member 30, than The quantity of the chip part of end edge portion stacking on the downside of the longitudinal direction of veutro exterior member 30 is more, can improve longitudinal direction upside end edge portion The intensity of the veutro exterior member 30 at place.The end edge portion is to act on larger power being caught when dressing diaper 1 by finger etc. Position, it is therefore, damaged so as to easily suppress veutro exterior member 30 by improving intensity as described above.For dorsal part exterior The non-skin lateral plate 42 and skin lateral plate 41 of part 40 are also identical (reference picture 3).

Fig. 4 A and Fig. 4 B are the figures illustrated to the variation of veutro exterior member 30, dorsal part exterior member 40.Should Fig. 4 A and Fig. 4 B are to represent the figure in longitudinal section for the diaper 1 of pants type shape.In Figure 4 A, in non-skin lateral plate 32 , the part 32f for stretching out and being turned back from longitudinal upper side end of skin lateral plate 31 is from skin side to cover absorbent main body 10 Mode be engaged.By forming as described above, the intensity of the longitudinal direction upside end edge portion of veutro exterior member 30 can also be improved. Also, the situation of the longitudinal direction upside end edge portion of absorbent main body 10 and the direct skin contact of wearer is suppressed, can make to wear The skin contact sense of waistline when wearing is good.

On the other hand, in figure 4b, non-skin lateral plate 32 (42) and skin lateral plate 31 (41) are mutually the same size. In this case, because non-skin lateral plate 32 (42) does not stretch out from skin lateral plate 31 (41), therefore, non-skin lateral plate 32 is not formed (42) intensity of the longitudinal direction upside end edge portion of return portion, veutro exterior member 30 and dorsal part exterior member 40 may be not enough. Then, in Fig. 4 B example, the skin of end edge portion on the upside of the longitudinal direction of veutro exterior member 30 and dorsal part exterior member 40 Side sets enhancing chip part 70 to improve the intensity at the position.Enhancing chip part 70 be with outside veutro exterior member 30 and dorsal part The different rectangular member of part 40 is filled, can be formed by non-woven fabrics etc..If such enhancing chip part 70, then can change material Material and size, therefore, can freely adjust veutro exterior member 30 and dorsal part exterior member according to use condition of diaper 1 etc. The intensity of 40 longitudinally outboard end edge portion, so, can more efficiently it be strengthened.Alternatively, it is also possible to being formed with non-skin The return portion 32f of lateral plate 32 and the structure for being configured with enhancing chip part 70.

The overlapping of hemad exterior member 30 of absorbent main body 10 is carried out as follows：Make absorbent main body 10 and veutro externally mounted part Longitudinal outboard end 30e of part 30 is not overlapping, and makes absorbent main body 10 and the portion than end 30e by the center side of longitudinal direction Divide 30c overlapping (reference picture 2).Similarly, absorbent main body 10 is carried out as follows to the overlapping of dorsal part exterior member 40：Make absorbability Main body 10 is not overlapping with longitudinal end 40e of dorsal part exterior member 40, and makes absorbent main body 10 and than end 40e by vertical To center side part 40c it is overlapping.In addition, nonoverlapping part 30e, the 40e are the waistline opening 1HB (figures for forming diaper 1 1) part.Moreover, at the part 30e, 40e, elastomeric element 35,45 described later is respectively throughout the part 30e, 40e in horizontal stroke Upward substantially total length and be continuously provided.

In the diaper 1 of present embodiment, absorbent main body 10 is configured to, and the end 30e of veutro exterior member 30 is vertical Upward length L30e is smaller (L30e than the end 40e length L40e in the vertical of dorsal part exterior member 40<L40e).That is, inhale The property received main body 10 is inclined to veutro exterior member 30 compared to dorsal part exterior member 40 on the whole and configured.If forming as described above, Urine can be efficiently absorbed in veutro (front side) when dressing diaper 1.Further, since absorbent main body 10 is close to veutro externally mounted part Part 30 and set, therefore, in the dorsal part of wearer, the area that buttocks upper area absorbability main body 10 covers is small.Due to this Region is that sweat easily accumulates and easily produces sultry region, therefore, the area covered by reducing absorbability main body 10, is held Easily make thermal diffusion and suppress sultry generation.But L30e and L40e magnitude relationship be not limited to above-mentioned relation or L30e >=L40e relation.

In addition, in the following description, will be nonoverlapping with absorbent main body 10 in the vertical in veutro exterior member 30 Region is in the 30e of end, is referred to as upper area 30e o with 10 nonoverlapping region of absorbent main body in the horizontal.In fig. 2, Upper area 30e o are in the region that is represented with oblique line of two horizontal upper lateral parts of veutro exterior member 30.In addition, outside veutro Fill in part 30, by the region between the upper area 30e o of both lateral sides, i.e. not overlapping with absorbent main body 10 in the vertical And the region overlapping with absorbent main body 10 is referred to as top center region 30ec in the horizontal.In addition, said here " on Side " refer to that diaper 1 is made to longitudinal upside in the state of pants type as Fig. 1, Fig. 4 A, 4B, in fig. 2 equivalent to The front side of longitudinal direction.

Similarly, will be in the vertical end with 10 nonoverlapping region of absorbent main body in dorsal part exterior member 40 It is in 40e, be referred to as upper area 40e o with 10 nonoverlapping region of absorbent main body in the horizontal.In addition, in dorsal part externally mounted part In part 40, region not overlapping and overlapping with absorbent main body 10 in the horizontal with absorbent main body 10 in the vertical is referred to as Top center region 40ec.

On the other hand, it is end by region overlapping with absorbent main body 10 in the vertical in veutro exterior member 30 It is in 30c, be referred to as lower zone 30c o with 10 nonoverlapping region of absorbent main body in the horizontal.Square region in figure 2 the lower 30c o are in the region of the two horizontal side lower part shadow representations of veutro exterior member 30.Also, by lower zone 30c o , overlapping with absorbent main body 10 in the vertical region be referred to as overlapping region 30c o 1, by it is in lower zone 30c o, vertical It is referred to as not overlapping region 30c o 2 with 10 nonoverlapping region of absorbent main body upwards.In addition, " lower section " said here refers to Diaper 1 is made to longitudinal downside in the state of pants type as Fig. 1, Fig. 4 A, 4B, in fig. 2 equivalent to longitudinal direction after Side.

Similarly, it is end 40c by region overlapping with absorbent main body 10 in the vertical in dorsal part exterior member 40 In, be referred to as lower zone 40c o with 10 nonoverlapping region of absorbent main body in the horizontal.Moreover, by lower zone 40c o , overlapping with absorbent main body 10 in the vertical region be referred to as overlapping region 40c o 1, by it is in lower zone 40c o, vertical It is referred to as not overlapping region 40c o 2 with 10 nonoverlapping region of absorbent main body upwards.

In these upper areas 30e o, 40e o and lower zone 30c o, 40c o, have in the horizontal defined long The joint-cutting spent and run through the wire of each exterior member 30,40 is that slit 50 is set at a prescribed interval on longitudinal direction and transverse direction Have multiple.Details on slit 50 will be explained below.

It is more along laterally lastex etc. is inserted between two pieces 31,32 involved by veutro exterior member 30 Individual elastomeric element 35,35 ..., also, the state to extend in the horizontal engages and is fixed on the piece 31,32.It is in addition, above-mentioned more Root elastomeric element 35,35 ... in the vertical interval while set along longitudinal arrangement.Similarly, in dorsal part exterior member Between two pieces 41,42 involved by 40, multiple elastomeric elements 45,45 ... such as lastex are inserted with along horizontal, also, Engaged with the state extended in the horizontal and be fixed on the piece 41,42.In addition, above-mentioned more elastomeric elements 45,45 ... are in longitudinal direction Set while upper interval along longitudinal arrangement.Thus, horizontal retractility is endowed veutro exterior member 30 and the back of the body Side exterior member 40, the retractility turn into the waistline opening 1HB of diaper 1 retractility.Elastomeric element 35 and 45 is except thickness, root Outside the detail specifications such as number, longitudinal allocation position, its basic structure is substantially identical to each other.

In addition, elastomeric element 35,45 near the central portion of transverse direction in the region overlapping with absorbent core 11, a part is not Continuously, retractility does not act on the region.Thus, the contraction of the transverse direction (width) of absorbent core 11 is suppressed, and therefore, is inhaled Generation of fold of the property received core 11 etc. is suppressed, and its skin-side surface of absorbent core 11 is easily maintained general planar.It is tied Fruit is the imbibition that can effectively prevent from hindering absorbent core 11, furthermore, it is also possible to suppress the row because of caused by the generation of fold Let out leakage of thing etc..

Fig. 5 is enlarged representation Fig. 2 region B figure.In the Fig. 5, the upper area in veutro exterior member 30 is represented One of the configuration for multiple slits 50 that 30e o and lower zone 30c o are formed.In addition, as shown in Fig. 2 in dorsal part externally mounted part Multiple slits 50 are also equipped with part 40, but because its basic structure and function are roughly the same with veutro exterior member 30, therefore, Mainly veutro exterior member 30 is illustrated herein, omitted the description for dorsal part exterior member 40.But in veutro externally mounted part Part 30 and dorsal part exterior member 40, the configuration of slit 50 and quantity can also be different.Alternatively, it is also possible to only in veutro exterior member 30 and dorsal part exterior member 40 in either one set slit 50 and be not provided with slit in the opposing party.

Slit 50 is the joint-cutting for running through veutro exterior member 30 in a thickness direction, along diaper 1 laterally across regulation Interval be in column-like manner formed with multiple.In addition, slit 50 can also be opened in a manner of having defined width in the vertical If part obtained from otch, if but considering the joint-cutting of the intensity, preferably wire of veutro exterior member 30.Hereinafter, with narrow Seam 50 illustrates for the joint-cutting such case of " wire " in the horizontal with defined length.

The slit 50 for being formed at veutro exterior member 30 in diaper 1 (is in Figure 5 veutro in the region in the outside of longitudinal direction The region of the upper side of exterior member 30) and the region of center side of longitudinal direction (be in Figure 5 the lower side of veutro exterior member 30 Region), configuration it is different with shape.In the example as shown in fig. 5, in lower zone 30c o formed with the first slit 51 and Two slits 52, up 30e o in region are formed with the second slit 52.First slit 51 for example (below, is also referred to as with the length of transverse direction For " slit length ") be 3mm, the mutual interval of adjacent in the horizontal the first slit 51 is (hereinafter also referred to as " slit spacing ") For 8mm mode transverse direction each row respectively formed with four.On the other hand, the second slit 52 is for example (narrow with the length of transverse direction Stitch length) be 2mm, mode that the mutual interval (slit spacing) of adjacent in the horizontal the second slit 52 is 8mm is horizontal Each row are respectively formed with five.It should be noted that the slit length of each slit 50 and interval are not limited to this, in addition, for Adjacent slit each other for, slit length and interval can also be different.By setting multiple slits 50, wearing urine as described above The gas permeability of veutro exterior member 30 during cloth 1 is ensured that, it is not easy to brings discomfort to wearer.

For diaper 1, in order to ensure enough gas permeabilities, the slit length of slit 50 is preferably more than 2mm.Narrow In the case that seam length is shorter than 2mm, when dressing diaper 1, the aperture area of slit 50 diminishes, it is possible to is no longer able to fully send out Wave the function as ventilation mouth.In addition, from the viewpoint of the intensity for ensuring veutro exterior member 30, the slit length of slit 50 Preferably below 10mm.In the case where slit length is longer than 10mm, because pullling veutro externally mounted part when dressing and taking off diaper 1 The power of part 30 and easily length direction end of slit 50 etc. produce crack, it is possible to be no longer able to substantially ensure that veutro exterior The intensity of part 30.In addition, if slit length is grown, the finger of wearer is easily stuck in the slit 50, may result in narrow Seam 50 splits because of the power of the finger.

In addition, as shown in the example of figure 5, the slit spacing of slit 50 is preferably longer than the slit length of the slit 50. Slit spacing be slit length below in the case of, adjacent slit 50 when dressing and taking off diaper 1 each other because pullling veutro The power of exterior member 30 and easily interconnect, may result in veutro exterior member 30 and split in the horizontal.By contrast, lead to Cross and slit spacing is set to longer than slit length, the slit 50 for easily suppressing adjacent is connected to each other.

In the diaper 1 of present embodiment, by adjusting slit 50 for each region of veutro exterior member 30 Shape and configuration, so as to ensure the good gas permeability of veutro exterior member 30, also, veutro externally mounted part can also be maintained The enough intensity of part 30.In Figure 5, in the lower zone 30c o of veutro exterior member 30, the first slit 51 is with the horizontal The mode that each row form four forms the side of five with each row in the horizontal formed with 6 row, the second slit 52 in the vertical Formula is in the vertical formed with 3 row.On the other hand, up region 30e o, the second slit 52 form five with each row in the horizontal Individual mode is in the vertical formed with 4 row.

Moreover, the combined length divided by upper area 30e o of slit 50 (joint-cutting) in upper area 30e o are in the vertical Value obtained from length L30e, combined length divided by lower zone 30c o than the slit 50 (joint-cutting) in lower zone 30c o exist Value is small obtained from length L30c on longitudinal direction.For example, in the case of Fig. 5 example, the slit length in upper area 30e o The aggregate value of degree is 2mm × 5 × 4 row=40mm.On the other hand, the aggregate value of the slit length in lower zone 30c o is 2mm × 5 × 3 row+3mm × 4 × 6 row=102mm.Therefore, (40mm/L30e)<The relation of (102mm/L30c) is set up.

The ratio ratio for the opening portion (part i.e. formed with slit 50) that the relation represents to be arranged at upper area 30e o is set The ratio of 30c o in region placed below opening portion is small.That is, in veutro exterior member 30, compared with upper area 30e o under Square region 30c o are with bigger ratio formed with joint-cutting (slit 50).Upper area 30e o are because of the finger when dressing diaper 1 Clamp and pull upward and act on the region of larger power, therefore, by the ratio for reducing the slit 50 formed in this region Example ensures intensity, damaged so as to suppress non-woven fabrics in this region.Conversely, as lower zone 30c o are directly drawn by finger etc. The possibility pulled is low, therefore, increases the ratio of slit 50 that is formed in this region further to improve gas permeability.That is, urinating In cloth 1, up reduce joint-cutting in region 30e o so that ensuring for intensity is preferential, in lower zone 30c o joint-cutting increase so that Good gas permeability is preferential.

Also, in the present embodiment, on the longitudinally below overlapping region 30c o 1 and longitudinal direction in lower zone 30c o The not overlapping region 30c o 2 of side, also adjust the ratio of slit 50.That is, the conjunction of the slit 50 (joint-cutting) in not overlapping region 30c o 2 Length divided by not value obtained from the length L30c2 of overlapping region 30c o 2 in the vertical are counted, than narrow in overlapping region 30c o 1 Value obtained from stitching the length L30c1 of the combined length divided by overlapping region 30c o 1 of 50 (joint-cuttings) in the vertical is small.For example, In the case of Fig. 5 example, the aggregate value of the slit length in overlapping region 30c o 2 is not 2mm × 5 × 2 row=20mm.It is another Aspect, the aggregate value of the slit length in overlapping region 30c o 1 are row+3mm × 4 of 2mm × 5 × 1 × 6 row=82mm.Therefore, (20mm/L30c2)<The relation of (82mm/L30c1) is set up.

In this case, in not overlapping region 30c o 2, compared with overlapping region 30c o 1, formed with joint-cutting (slit 50) Ratio it is low.Due to the not overlapping region 30c o 2 in lower zone 30c o compared with overlapping region 30c o 1 close to upper area 30e o, therefore, upper area 30e o are pullled upward when dressing diaper 1, so as to also easily pull not overlay region upward Domain 30c o 2.In addition, overlapping region 30c o 1 are overlapping with absorbent core 11 in the vertical, without overlapping region 30c o 2 in the vertical It is not overlapping with absorbent core 11.Therefore, in overlapping region 30c o 1 as caused by absorbent core 11 drag effect in upward Tensile force, and the resistance as caused by absorbent core 11 is not easy to act on tensile force in not overlapping region 30c o 2.Therefore, In not overlapping region 30c o 2, the ratio of the slit 50 formed in the zone is reduced so that ensuring for intensity is preferential.The opposing party Face, in overlapping region 30c o 1, the ratio of slit 50 that is formed in the zone is improved further to improve gas permeability.

In addition, in order to ensure veutro exterior member 30 intensity, it is necessary to each column for transverse direction the slit 50 that sets Ratio also account for.That is, should not only consider in certain region (for example, lower zone 30c o etc. have defined area Region) in the ratio of slit 50 that sets, and multiple slits 50 for setting on the same line on certain row should be considered Ratio.Because：If slit 50 laterally long forms very more on certain row, the veutro exterior member 30 in the row Remitted its fury, it is damaged to may result in the veutro exterior member 30.

In the present embodiment, in upper area 30e o or lower zone the 30c o of veutro exterior member 30 transverse direction The combined length of the slit length for the slit 50 that wherein one row are set, than being provided with the length of the region of the slit 50 in the horizontal It is 1/2 small.For example, in Figure 5, the effective lengths of upper area 30e o in the horizontal are (except the side edge part 30se as linking part Outside lateral length) be 59mm, and up in region 30e o wherein one row set the second slit 52 slit length Combined length be 2mm × 5=10mm, the small (10mm of half length than 59mm<59mm/2).Similarly, lower zone 30c o Length in the horizontal is 59mm, and the slit length for the first slit 51 that wherein one row in lower zone 30c o are set Combined length is 3mm × 4=12mm, the small (12mm of half length than 59mm<59mm/2).So, by making in the same line On the combined length of the length of slit (joint-cutting) that makes length direction align and arrange than material (be herein veutro exterior member 30) half of length is small, and the intensity of the material is ensured that, is easier to suppress the breakage of diaper 1 when dressing and taking off.

The figure that the situation of the deformation of slit 50 when Fig. 6 A are to wearing diaper 1 illustrates.Fig. 6 B are in comparative example Slit 50 deformation the figure that illustrates of situation.When dressing diaper 1, veutro exterior member is lifted because pullling upward The action of 30 (dorsal part exterior members 40), the power of above-below direction act on veutro exterior member 30 slit 50 set.And And due to by power as described above (tensile force), so the shape of slit 50 changes.

Tensile force upward when as shown in Figure 6A, because of wearing diaper 1, is acted on narrow towards the upper and lower power Fv of longitudinal direction Seam 50.In addition, when dressing diaper 1, because being arranged at (the bullet of elastomeric element 35 of veutro exterior member 30 (dorsal part exterior member 40) Property part 45) horizontal convergent force, act on slit 50 towards the power Fh of horizontal left and right.As a result, slit 50 is because of power Fv and extend in the vertical, also, because power Fh also extends in the horizontal, so as to the shape of almost diamond as being deformed into Fig. 6 A Shape.Because slit 50 as described above is deformed into rhombus from wire, therefore, heat and water between the skin and extraneous air of wearer Divide and moved easily by slit 50, gas permeability can be made more preferable.

By contrast, in fig. 6b, as comparative example, represent that convergent force horizontal as caused by elastomeric element 35 does not fill It is allocated as the situation for veutro exterior member 30.In the case of comparative example, because the upper and lower power Fv only towards longitudinal direction makees For slit 50, therefore, slit 50 is easily deformed as such shape longitudinally grown shown in Fig. 6 B.For longitudinal direction as Fig. 6 B For long shape, good gas permeability is difficult to ensure that compared with Fig. 6 A rhombus.Further, since it is originally laterally long shape Slit 50 be significantly deformed into longitudinal length, therefore, produce excessive stress in the region formed with the slit 50, may lead Cause veutro exterior member 30 easily damaged.

It is narrow by effectively acting on the convergent force as caused by elastomeric element 35,45 as Fig. 6 A in diaper 1 Seam 50, so as to so that gas permeability is more preferable.Especially, in the present embodiment, the elasticity that can telescopically set in the horizontal Part 35 is provided with multiple at a prescribed interval in the vertical, and laterally long slit 50 is configured at elastic portion adjacent in the vertical Between part 35.That is, the structure that slit 50 is clipped by elastomeric element 35 in the vertical is turned into.Thus, by adjacent in the vertical Two elastomeric elements 35 caused by convergent force easily act on the slit 50 configured between them, the change of the rhombus of slit 50 Shape is promoted.In addition, in the present embodiment, slit 50 and elastomeric element 35,45 are each configured to, the length direction of slit 50 It is parallel with the telescopic direction of elastomeric element 35,45.If being configured with slit 50 and elastomeric element 35,45 as described above, wearing The telescopic direction for wearing the draw direction acted on during diaper 1 and elastomeric element 35,45 is intersected.Thus, it is longitudinal and transverse direction Dynamic balance acts on well slit 50, and the slit 50 can be made to be deformed into such good rhombus shown in Fig. 6 A.

In addition, as shown in Fig. 2 in diaper 1, in the top center area of veutro exterior member 30 (dorsal part exterior member 40) Domain 30ec, 40ec do not form joint-cutting (slit 50).In other words, the joint-cutting (slit in top center region 30ec, 40ec 50) combined length is zero.Because the top center region 30ec, 40ec are the thermal capacitances at belly and back when dressing diaper 1 The region easily accumulated, it is therefore preferable that configuring joint-cutting to improve gas permeability.But because the region is also for making absorbability master The part that the body (such as crotch) of body 10 and wearer are fit and continually pull upward, therefore, if not ensuring enough Intensity, it is damaged to may result in diaper 1.Then, in the present embodiment, up middle section 30ec, 40ec is not set Slit 50 is put so that ensuring for intensity is preferential.Thus, good fit and durability can be realized when dressing diaper 1.

But it is zero to be not necessarily required to make the slit 50 that up middle section 30ec, 40ec is set, and can also be formed few Amount configures the structure of shorter slit.Now, the longitudinally outboard in veutro exterior member 30 and dorsal part exterior member 40 is passed through End edge portion sets enhancing chip part 70 as described above, so as to also ensure that intensity.
