<About the joint-cutting (slit 50) for being set to exterior member 30,40>
Fig. 5 is the figure for the region B that amplification indicates Fig. 2.In the Fig. 5, the upper area in veutro exterior member 30 is indicated
An example of the configuration for multiple slits 50 that 30e o and lower zone 30c o is formed.In addition, as shown in Fig. 2, in back side externally mounted part
Multiple slits 50 are also equipped on part 40, but since its basic structure and function are roughly the same with veutro exterior member 30,
Mainly veutro exterior member 30 is illustrated herein, is omitted the description for back side exterior member 40.But in veutro externally mounted part
Part 30 and back side 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 back side exterior member 40 in either setting slit 50 and be not provided with slit in another 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 formed in a row it is multiple.In addition, slit 50 is also possible to open in a manner of having defined width in the longitudinal direction
If part obtained from notch, if but considering the intensity of veutro exterior member 30, preferably linear joint-cutting.Hereinafter, with narrow
Seam 50 is illustrated for the joint-cutting such case of " threadiness " horizontally with defined length.
The slit 50 for being formed in veutro exterior member 30 in diaper 1 (is veutro in Fig. 5 in the region in longitudinal outside
The region of the upper side of exterior member 30) and the region of longitudinal center side (be the lower side of veutro exterior member 30 in Fig. 5
Region), configure it is different with shape.The first slit 51 and are formed in lower zone 30c o in the example shown in FIG. 5,
Two slits 52,30e o in region is formed with the second slit 52 above.First slit 51 is for example with lateral length (hereinafter, also referred to as
For " slit length ") it is 3mm, the horizontally adjacent mutual interval of the first slit 51 (hereinafter also referred to as " slit spacing ")
For 8mm mode there are four lateral each formation of each column.On the other hand, the second slit 52 is for example (narrow with lateral length
Seam length) be 2mm, mode that horizontally the mutual interval (slit spacing) of adjacent second slit 52 is 8mm is in transverse direction
There are five each each formation of column.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 being set as described above multiple slits 50, wearing urine
The gas permeability of veutro exterior member 30 when cloth 1 is ensured that, it is not easy to bring discomfort to wearer.
For diaper 1, in order to ensure enough gas permeabilities, the slit length of slit 50 is preferably 2mm or more.Narrow
In the case that seam length ratio 2mm is short, when dressing diaper 1, the opening area of slit 50 becomes smaller, it is possible to be no longer able to sufficiently 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 10mm or less.In the case where slit length ratio 10mm long, because pullling veutro externally mounted part when dressing and taking off diaper 1
The power of part 30 and be easy length direction end of slit 50 etc. generate crack, it is possible to be no longer able to substantially ensure veutro exterior
The intensity of component 30.In addition, the finger of wearer is easy to be stuck in the slit 50 if slit length is long, 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 is in slit length situation below, and adjacent slit 50 is each other because pullling veutro when dressing and taking off diaper 1
The power of exterior member 30 and be easy interconnect, may result in veutro exterior member 30 and horizontally split.In contrast, lead to
It crosses and slit spacing is set as longer than slit length, be easy to inhibit adjacent slit 50 to be 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, can also maintain veutro externally mounted part
The enough intensity of part 30.In Fig. 5, in the lower zone 30c o of veutro exterior member 30, the first slit 51 is with horizontally
The mode that each column form four is formed with 6 column in the longitudinal direction, and the second slit 52 forms five sides with horizontally each column
Formula is formed with 3 column in the longitudinal direction.On the other hand, region 30e o, the second slit 52 form five with horizontally each column above
A mode is formed with 4 column in the longitudinal direction.
Moreover, the combined length of the slit 50 (joint-cutting) in upper area 30e o divided by upper area 30e o in the longitudinal direction
It is worth obtained from length L30e, the combined length than the slit 50 (joint-cutting) in lower zone 30c o exists divided by lower zone 30c o
Value obtained from longitudinal length L30c is small.For example, the slit in upper area 30e o is long in the case where the example of Fig. 5
The aggregate value of degree is 2mm × 5 × 4 column=40mm.On the other hand, the aggregate value of the slit length in lower zone 30c o is 2mm
× 5 × 3 column+3mm × 4 × 6 column=102mm.Therefore, (40mm/L30e)<The relationship of (102mm/L30c) is set up.
The relationship indicates that the ratio ratio for the opening portion (being formed with the part of slit 50) for being set to upper area 30e o is set
The ratio of the opening portion of 30c o in region placed below is small.That is, in veutro exterior member 30, compared with upper area 30e o under
Square region 30c o is formed with joint-cutting (slit 50) with bigger ratio.Upper area 30e o is because of the finger when dressing diaper 1
The region of biggish power is clamped and pulls and act on upwards, therefore, by the ratio for reducing the slit 50 formed in this region
Example ensures intensity, thus inhibit in this region non-woven fabrics it is damaged.Conversely, as lower zone 30c o is directly drawn by finger etc.
A possibility that pulling is low, therefore, increases the ratio of the slit 50 formed in this region to further increase gas permeability.That is, urinating
In cloth 1, reduce joint-cutting in region 30e o above 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 adjusts the ratio of slit 50.That is, the not conjunction of the slit 50 (joint-cutting) in overlapping region 30c o 2
It counts length to be worth divided by obtained from not overlapping region 30c o 2 length L30c2 in the longitudinal direction, than narrow in overlapping region 30c o 1
The combined length for stitching 50 (joint-cuttings) is small divided by value obtained from the length L30c1 in the longitudinal direction of overlapping region 30c o 1.For example,
In the case where the example of Fig. 5, the aggregate value of the slit length in overlapping region 30c o 2 is not 2mm × 5 × 2 column=20mm.It is another
Aspect, the aggregate value of the slit length in overlapping region 30c o 1 are 2mm × 5 × 1 column+3mm × 4 × 6 column=82mm.Therefore,
(20mm/L30c2)<The relationship of (82mm/L30c1) is set up.
In this case, in not overlapping region 30c o 2, compared with overlapping region 30c o 1, it is 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
Therefore 30e o pulls upper area 30e o when dressing diaper 1 upwards, to also be easy to pull not overlay region upwards
Domain 30c o 2.In addition, overlapping region 30c o 1 is Chong Die with absorbent core 11 in the longitudinal direction, in the longitudinal direction without overlapping region 30c o 2
It is not Chong Die with absorbent core 11.Therefore, the drag effect generated in overlapping region 30c o 1 by absorbent core 11 is in upwards
Drawing force, and be not easy to act on drawing force by the resistance that absorbent core 11 generates 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.Another party
The ratio of the slit 50 formed in the zone is improved to further increase gas permeability in overlapping region 30c o 1 in face.
In addition, needing in order to ensure the intensity of veutro exterior member 30 to the slit 50 being arranged for lateral each column
Ratio also account for.That is, should not only consider in certain region (for example, lower zone 30c o etc. has defined area
Region) in the ratio of slit 50 that is arranged, and should consider multiple slits 50 for being arranged on the same line on certain column
Ratio.This is because：If slit 50 laterally long forms very more on certain column, the veutro exterior member 30 in the column
Remitted its fury, it is damaged to may result in the veutro exterior member 30.
In the present embodiment, in the transverse direction of the upper area 30e o of veutro exterior member 30 or lower zone 30c o
The wherein combined length of the slit length of the slit 50 of a column setting, than being provided with the length of the region of the slit 50 horizontally
It is 1/2 small.For example, the effective length of upper area 30e o horizontally is (except the side edge part 30se as linking part in Fig. 5
Except lateral length) be 59mm, and above in region 30e o wherein one column setting 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 horizontally is 59mm, and the wherein slit length of the first slit 51 of a column setting in lower zone 30c o
Combined length is 3mm × 4=12mm, the small (12mm of half length than 59mm<59mm/2).In this way, by making in the same line
On be aligned length direction and the combined length of the length of slit (joint-cutting) that arranges than material (is herein veutro exterior member
30) half of length is small, and the intensity of the material is ensured that, is easier to inhibit diaper 1 damaged when dressing and taking off.
The figure that the situation of the deformation of slit 50 when Fig. 6 A is to wearing diaper 1 is illustrated.Fig. 6 B is in comparative example
Slit 50 deformation the figure that is illustrated of situation.When dressing diaper 1, veutro exterior member is lifted because pullling upwards
The movement of 30 (back side exterior members 40), the power of up and down direction act on the slit 50 being arranged on veutro exterior member 30.And
And due to by power as described above (drawing force), so the shape of slit 50 changes.
Drawing force upwards when as shown in Figure 6A, because of wearing diaper 1, acts on narrow towards longitudinal upper and lower power Fv
Seam 50.In addition, when dressing diaper 1, because being set to the 35 (bullet of elastomeric element of veutro exterior member 30 (back side exterior member 40)
Property component 45) lateral convergent force, act on slit 50 towards the power Fh of lateral left and right.As a result, slit 50 is because of power
Fv and extend in the longitudinal direction, also, because power Fh also horizontally extends, to be deformed into the shape of almost diamond as Fig. 6 A
Shape.Since slit 50 as described above is deformed into diamond shape from threadiness, heat and water between the skin and outside air of wearer
Partial volume is easily moved by slit 50, and gas permeability can be made more preferable.
In contrast, in fig. 6b, as comparative example, indicate that the lateral convergent force generated by elastomeric element 35 does not fill
The case where being allocated as veutro exterior member 30.In the case where comparative example, due to only making towards longitudinal upper and lower power Fv
For slit 50, therefore, slit 50 is easily deformed as such shape longitudinally grown shown in Fig. 6 B.For longitudinal as Fig. 6 B
For long shape, good gas permeability is difficult to ensure compared with the diamond shape of Fig. 6 A.In addition, due to being laterally long shape originally
Slit 50 be significantly deformed into longitudinal length, therefore, excessive stress is generated in the region for being formed with the slit 50, may led
Veutro exterior member 30 is caused to be easy breakage.
It is narrow by effectively acting on the convergent force generated 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 horizontally can be telescopically arranged
Component 35 is provided with multiple at a prescribed interval in the longitudinal direction, and laterally long slit 50 is configured at elastic portion adjacent in the longitudinal direction
Between part 35.That is, becoming the structure that slit 50 is clipped by elastomeric element 35 in the longitudinal direction.As a result, by adjacent in the longitudinal direction
Two elastomeric elements 35 generate convergent force be easy to act on the slit 50 configured between them, the change of the diamond shape 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 of the draw direction and elastomeric element 35,45 that are acted on when wearing diaper 1 is intersected.It is longitudinal and transverse direction as a result,
Dynamic balance acts on well slit 50, and the slit 50 can be made to be deformed into such good diamond shape 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 (back side 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.Since the top center region 30ec, 40ec are the thermal capacitances of abdomen and back when dressing diaper 1
The region easily accumulated, it is therefore preferable that configuring joint-cutting to improve gas permeability.But since 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 upwards, therefore, if not ensuring enough
Intensity, it is damaged to may result in diaper 1.Then, in the present embodiment, middle section 30ec, 40ec is not set above
Slit 50 is set so that ensuring for intensity is preferential.Good fitness and durability may be implemented when dressing diaper 1 as a result,.
But it is not necessarily required to make the slit 50 0 of middle section 30ec, 40ec setting above, it also may be constructed few
Amount configures the structure of shorter slit.At this point, passing through the longitudinally outboard in veutro exterior member 30 and back side exterior member 40
Enhancing chip part 70 as described above is arranged in end edge portion, so that intensity be also ensured.
