The 11 fixed part 1bk of band base material 11a are (in the figure 7 by the part 1bk of shadow representation；Hereinafter referred to as fixed band is fixed
Portion 1bk).It is respectively formed in the second side flap 1bsf corresponding with each fixed band 11 more specifically, cutting line 1c.Respectively cut line
1c, which is formed as passing through from the part 1bHB as waist opening portion 1HB in the second waist portion 1b, is located at fixed band fixed part 1bk
The part 1bHL that is positioned against as leg-openings portion 1HL of laterally inboard extend.
It as shown in Figure 2 B, as a result can be rapidly de- from the low weight baby 101 for posture of lying prostrate shown in Fig. 2A
Fall diaper 1dp.That is, as shown in Figure 2 A, diaper 1dp usually is such that the second waist portion 1b for being fixed with fixed band 11 is located at low body
The mode of the back side of weight baby 101 is worn by low weight baby 101.Therefore, in posture of lying prostrate, the second waist portion 1b is located at vertical
Top on direction.It, can be as described above using the fixation band for cutting line 1c and cutting the second waist portion 1b using diaper 1dp
Fixed part 1bk (Fig. 2 B).This enables the hook portion 11m of fixed band 11 to be detached with the second waist portion 1b.This can make the first waist
Body portion 1a is detached with the second waist portion 1b and is opened diaper 1dp, and the hook portion 11m for fixing band 11 remains secured to the first waist
Portion 1a.Therefore, the second waist portion 1b finally is pulled out towards rear (towards leg), and can be from the under-weight in posture of lying prostrate
Baby 101 takes off diaper 1dp.
The perforation for cutting line 1c is the aggregate of seam linearly in the horizontal.That is, multiple linear seams (do not show
Going out) through-thickness extends through particular patch 4 and 5 in multiple 4,5 and 6；Multiple 4,5 and 6 the second side flaps of composition
1bsf.Also, multiple seams are arranged along the direction that line 1c to be extended is cut.Cuttability appropriate etc. is considered to design the length of seam
Degree and pitch.Specifically, the length of seam is illustrated as 1mm-3mm, the interval between adjacent seam is (in other words, between seam not
There are the length of the part of seam) it is illustrated as 0.5mm-2mm.It can be said that the pitch of aforementioned seam is the sum of the length and interval of seam.
In this example, as shown in fig. 7, be formed in a second side flap 1bsf cut line 1c and be formed in it is another
In second side flap 1bsf to cut line 1c symmetrical about the center line C1 lines in the transverse direction of diaper 1dp.Respectively cutting line 1c is
Substantially J-shape and by being constituted along longitudinal straight section 1cL and in the curved surface portion 1cB of curved shape.
Straight section 1cL is using the part 1bHB as waist opening portion 1HB of the second waist portion 1b as starting point；Change speech
It, straight section 1cL is using the longitudinal external end edge 1be1 of the second waist portion 1b as starting point.Then, straight section 1cL
Extend towards longitudinal medial along longitudinal straight line is parallel to, and reaches lengthwise position identical with fixed band 11 or arrival
The position of lengthwise position more identical than this slightly inwardly.Straight section 1cL is connected in the position that straight section 1cL is reached
Curved surface portion 1cB.Curved surface portion 1cB extends further towards longitudinal medial.More specifically, with curved surface portion 1cB
Extend towards longitudinal medial, curved surface portion 1cB is bent with specific curvature towards lateral outer side；Curved surface portion 1cB is final
The part 1bHL as leg-openings portion 1HL for reaching the second waist portion 1b, that is, in the transverse direction for eventually arriving at the second waist portion 1b
External end edge 1be2.
Using the path for cutting line 1c, line 1c is cut from laterally inboard completely around fixed band fixed part 1bk.Cause
This can make the fixed hook portion 11m with fixed part 1bk together with fixed band 11 and fixed band fixed part when line 1c is cut in cut-out
1bk is detached with the second waist portion 1b.
In addition, if including aforementioned curved surface portion 1cB, then second can be reached according to relatively short path by cutting line 1c
External end edge 1be2 in the transverse direction of waist portion 1b.That is, the path for cutting line 1c can not made substantially to extend towards longitudinal medial
In the case of setting cut line 1c.This can be effectively prevented can when the path for cutting line 1c substantially extends towards longitudinal medial
The problem of capable of occurring, such as following problem：When path reaches the first side flap 1asf (Fig. 3), a part of line 1c is cut
It can be trapped between the leg that the abdomen of the low weight baby 101 in positioning posture is separated with it in M shapes, this makes it difficult to cut
Offline 1c.
In the example in figure 7, line 1c is cut to be arranged in the second side flap 1bsf.However, the invention is not limited thereto.That is,
In some cases, crotch side flap 1msf can be extended much further by cutting a part of of line 1c.However, excessive extension
Amount can cause to be difficult to cut off the problem of cutting line 1c, this is because cut line 1c be easy to be trapped in the abdomen of low weight baby 101 with
It is between the separated leg of M shapes, or because shearing length is longer.Therefore, which is preferably small.
As shown in the schematic sectional view of Fig. 7, line 1c is cut at least formed at three-dimensional rivel piece 6, leakage prevention sheet 4 and outer load
The position of 5 through-thickness stacking.In the present embodiment, it cuts line 1c and is formed in outer load 5 and leakage prevention sheet 4 (with first
It is corresponding) in, but be not formed in three-dimensional rivel piece 6 (corresponding with second).
This can prevent the hook portion 11m when wearing diaper 1dp from unexpectedly being cut off from the second waist portion 1b；That is, can prevent
Diaper 1dp is unavailable in this way.That is, when putting on diaper 1dp for low weight baby 101, as shown in Figure 2 C, second is being used
In the case that the fixed band 11,11 of a pair of waist portion 1b draws the second waist portion 1b of diaper 1dp towards both lateral sides, by band 11,
11 hook portion 11m is fixed to the target area 1at of the first waist portion 1a.In this case, line can be cut by not having
The three-dimensional rivel piece 6 of 1c receives the lateral pull for cutting line 1c (Fig. 7) that may act on outer load 5 and leakage prevention sheet 4.Thus,
The fracture for cutting line 1c of outer load 5 and leakage prevention sheet 4 can be effectively prevented from.This can prevent the hook portion 11m of fixed band 11 from
Second waist portion 1b is unexpectedly cut off.
It is used as cutting the perforation of line 1c since three-dimensional rivel piece 6 does not have, so the certainly row of preventing of three-dimensional rivel piece 6
The non-skin side surface leakage of the outside load of the skin-side surface of drainage from three-dimensional rivel piece 65.Therefore, it is possible to be effectively prevented
It is leaked caused by cutting the perforation of line 1c.
When operator will put on new diaper 1dp for low weight baby 101, and from terms of the skin side of diaper when diaper,
Operator cannot see in the skin-side surface of three-dimensional rivel piece 6 cuts the perforation of line 1c (referring to Fig. 3).Thus, operator will
It will not worry from the leakage for cutting line 1c, and operator being capable of securely more changing babies' napkin.
Between three-dimensional rivel piece 6 and leakage prevention sheet 4, with the appropriate pattern of Ω shapes pattern, spiral pattern etc. or with
Solid mode is coated with hot-melt adhesive.Thus, as shown in Figure 8 A, bonding agent is used as so that the joint portion Q that piece 6 and 4 engages.When
In order to by diaper 1dp from low weight baby 101 take off and when along cutting line 1c and cut off the second waist portion 1b, along outer load 5
It can be rapidly transferred to not have the three-dimensional rivel piece 6 for cutting line 1c with the cut-out power for cutting line 1c effects of leakage prevention sheet 4.Cause
And three-dimensional rivel piece 6 can be quickly shut off along the line 1c that cuts of outer load 5 and leakage prevention sheet 4, as a result, can be along cutting
Line 1c successfully cuts off fixed band fixed part 1bk from the second waist portion 1b.
In order to which three-dimensional rivel piece 6 will should be reliably transmitted to along the cut-out power for cutting line 1c effects, it is preferred that as schemed
Shown in 8A, joint portion Q is formed as cutting line 1c across this with spreading the substantially whole length for cutting line 1c of leakage prevention sheet 4.Alternatively,
Preferably, as shown in Figure 8 B, joint portion Q, Q is formed in the both lateral sides for cutting line along line 1c is cut.
However, the joint portion Q of Fig. 8 A and Fig. 8 B need not spread the substantially whole length landform for cutting line 1c of leakage prevention sheet 4
At.That is, as long as joint portion Q is formed in at least part for cutting line 1c, from leakage prevention sheet 4 to the cut-out power energy of three-dimensional rivel piece 6
Enough it is reliably transmitted at least part.Preferably, be formed in cut at least part of joint portion Q of line 1c can
Aforementioned cut-out power is set reasonably to transmit.
In order to improve the cuttability of three-dimensional rivel piece 6, it is desirable to constitute being averaged for the composition fiber of the non-woven fabrics of piece 6
Fibre length is less than 45mm, it more desirable to, it is less than 20mm.In the case where this composition fiber is short, the fracture strength of non-woven fabrics is suitable
It is local small.Therefore, it is formed even if as described above not in three-dimensional rivel piece 6 and cuts line 1c, piece 6 also can be along with leakage prevention sheet 4
The cut-out for cutting line 1c and quickly cut off.As a result, the cut-out for cutting line 1c can cause fixed band fixed part 1bk from second
Waist portion 1b is successfully cut off.
In addition, in order to which the longitudinal external end edge 1be1 of the second waist shown in Fig. 7 portion 1b successfully starts to cut
Offline 1c, it is desirable to the fiber-wall-element model of the non-woven fabrics of three-dimensional rivel piece 6 along cut off line 1c positioned at the end of external end edge 1be1
The extending direction for cutting off line 1c at portion 1ce1.In the example in figure 7, the end 1ce1 of line 1c is cut along being longitudinally extended
In straight section 1cL.The fiber-wall-element model of piece 6 is along longitudinal direction；That is, the fiber-wall-element model meets preceding description.This can be not right
In the case that three-dimensional rivel piece 6 generates big fracture resistance, successfully from the longitudinal external end edge 1be1 of the second waist portion 1b
Start to cut line 1c.
In this example, leakage prevention sheet 4 is with elastomeric resin film by being made, the elasticity of such resin film Yin Qigao and
Usually there is the cuttability of difference.Therefore, in this example, formed in leakage prevention sheet 4 as described above and cut line 1c.Cut line 1c energy
Enough elasticity of resisting successfully cuts leakage prevention sheet 4.It is attributed to and cuts off line 1c, this is contributed effectively to from the second waist portion 1b successfully
Cut off fixed band fixed part 1bk.
In this example, it is attributed to the method about perforation, cuts the easiness of line 1c according to lengthwise position not
It is same and different.For example, as shown in the left part of Fig. 7, it is assumed that cut part 1c1,1c2,1c3 that line 1c is divided into three longitudinal directions, cut off
The easiness and part 1c1,1c2,1c3 for cutting line 1c are accordingly set.More specifically, as three parts 1c1,1c2,1c3
One of first part 1c1 be located at include the second waist portion 1b the part 1bHB as waist opening portion 1HB region
In.First part 1c1 is constituted by holding scissile perforation.Second as the other of three parts 1c1,1c2,1c3
Part 1c2 be located at include in longitudinal region of the fixation with the corresponding positions fixed part 1bk.Second part 1c2 is by than first
The perforation of part 1c1 is difficult to the cut-out cut off perforation and constitutes.Part III 1c3 as remaining part 1c3 is above-mentioned curve
Shape part 1cB.Part III 1c3 is made of the easy cut-out perforation that the perforation with first part 1c1 is same type.
It is attributed to the hard-to-break perforation of second part 1c2 in this way, effectively prevents working as to wear to low weight baby 101
Diaper 1dp and whens fixed band 11,11 each towards layback lateral out, cuts line 1c and is unexpectedly broken.In addition, from low weight baby
101 when taking off diaper 1dp, and the easy cut-out perforation of first part 1c1 makes it possible to from the part 1bHB as waist opening portion 1HB
Easily start to cut diaper 1dp.Meanwhile be attributed to easily cut-out perforation and can be along the curve-like as Part III 1c3
The aim curve shape of part 1cB accurately cuts off curved surface portion 1cB.
Being set by for the above-mentioned easiness to cut-out perforation changes the length for the seam being included in perforation to realize, this is adopted
With in this example.That is, in this example, the pitch of seam maintains length that is identical and stitching different.Therefore, the length of seam is cut with edge
The ratio of the unit length of the extending direction of offline 1c is different from part 1c1,1c3 in the 1c2 of part.In general, tool
There is the perforation of big ratio to be easy cut-out, the perforation with small ratio is difficult to cut off.Therefore, in this example, in second part 1c2
Ratio be less than first part 1c1 in ratio and Part III 1c3 in ratio.
In this example, as shown in figure 5, in each first side flap 1asf, 1asf of the first waist portion 1a, cutting line
1ca is constituted by perforating.In other words, in each first side flap 1asf, cutting line 1ca is formed as from longitudinal external end edge
1asfe extends towards longitudinal medial.The forming position in the horizontal of cutting line 1ca and cut line 1c in the second side flap
The forming position of the longitudinal external end edge 1bsfe of 1bsf is identical.
This allows to arrange relatively wide interval between cutting line 1ca, 1ca in the first waist portion 1a.Therefore, it is cutting off
After the perforation of cutting line 1ca, 1ca, by the part 1am between cutting line 1ca, 1ca for the first waist portion 1a that turns back,
The abdomen of low weight baby 101 can be made to be exposed.This is being needed to the suitable of abdomen progress light treatment of baby etc.
It is effective in the case of processing.Because after cutting off these cutting lines, cutting line 1ca, 1ca are easy transversely to open,
So the first waist portion 1a transversely can be deformed flexibly.As a result, the big low weight baby 101 of abdomen can cosily be worn
Diaper 1dp.
Fig. 9 and Figure 10 is the definition graph for cutting line 1c ', 1c " of variation example respectively.Line is respectively cut in the variation example of Fig. 9
1c ' does not include curved surface portion 1cB, only includes straight section 1cL.More specifically, in variation example, cut with aforementioned
Line 1c is compared, and the position for respectively cutting line 1c ' is located opposite from lateral outer side.This makes it possible to be used only along being longitudinally extended
Single straight section 1cL is fixed with fixed part 1bk to cut.Line 1c ' is cut using this, only cuts off single straight section
1cL makes its cut-out be easier.Therefore, it is possible to not substantially deviate cut line 1c ' position carry out cut-out diaper 1dp in the case of
Accurately cut line 1c '.In this example, such as from, it is apparent that at the position for respectively cutting line 1c ', there are solids in Fig. 9
Rivel piece 6 and outer load 5, but leakage prevention sheet 4 is not present.Therefore, in this variant, outer load 5 and it is formed with and cuts line 1c '
First correspondence, three-dimensional rivel piece 6 with do not formed cut second of line 1c ' it is corresponding.These pieces 5,6 are using as joint portion
The hot-melt adhesive of Q (not shown) and engage.
On the other hand, the line 1c " that cuts in the variation example of Figure 10 is substantially U-shaped to solid around fixed band in three gussets
Determine portion 1bk.For respectively cutting line 1c ", beginning Ps is located in the transverse direction of the second side flap 1bsf of the second waist portion 1b most
External end edge 1bsfee cuts line 1c " so that fixed be located at the mode of the substantially inside in U-shaped path from the beginning with fixed part 1bk
End extends, and eventually arrives at the outermost ora terminalis in the transverse direction of the second side flap 1bsf identical with beginning Ps；Line 1c is cut " to arrive
Position Pe at where up to outermost ora terminalis 1bsfee is the terminal Pe for cutting line 1c ".In this variant, outer load 5 and formation
Have first correspondence for cutting line 1c ", three-dimensional rivel piece 6 with do not formed cut second of line 1c " it is corresponding.These 5,6 profits of piece
It is engaged with the hot-melt adhesive as joint portion Q (not shown).
