The rigidity of the end edge of disposable diaper, the situation that can prevent the end edge of disposable diaper from unexpectedly rolling.
The pelvic bone that the 1st region R1 on the outside of the width direction of absorbent cores 40a is configured in the side with wearer is suitable
Position.Since joint portion row are not arranged by the 1st region R1, maintain the contractility of waistline pars contractilis, thus with equipped with joint portion
The 3rd region R3 contractilities that compare of row are higher.By the waist for forcefully fitting in the side of wearer by the 1st region R1
Bone increases to the stickiness of waistline.The gap between body and disposable diaper can be reduced, the leakage of excreta is inhibited.
Since joint portion 87 is not arranged by the 2nd region R2, maintain the contractility of waistline pars contractilis 85, thus with equipped with engagement
The 3rd region R3 contractilities that compare of portion's row are higher.2nd region R2 is relatively easy flexible, can be absorbed from suction by the 2nd region R2
The deformation that the sides core 40a generate is received, the deformation of absorbent cores 40a is inhibited to travel to the end edge of the 3rd region R3, disposable diaper.Cause
And it is able to maintain that the stickiness of the end edge of disposable diaper.
The end edge that the end edge of joint portion row 87L is configured at disposable diaper is then preferable.By making to prolong along its length
The fold stretched reaches the end edge of disposable diaper, to be not easy disposable diaper end edge, it is formed about along width
The folding starting point that direction extends.Therefore, it is possible to prevent after causing disposable diaper by the folding starting point extended in the width direction
Ora terminalis tilts.
At least part of 2nd region R2 is configured then more preferable than the positions of absorbent cores 40a rearward.2nd region R2's
At least part configuration is between the 3rd region R3 and absorber.Positioned at than the regions rearward absorbent cores 40a not with absorber one
With deformation, it is not easy directly to propagate the deformation of absorber.The 2nd region R2 can be utilized to absorb the deformation generated from the sides absorbent cores 40a,
Effectively inhibit the situation that the deformation of absorbent cores 40a is traveled to the 3rd region R3.
Include the flesh for being located at the opposite surface side of the skin of waistline pars contractilis using joint portion and sheet material that waistline pars contractilis engages
Skin dough sheet (top flat 50, flank 70 and egative film 60a) and (outer with respect to the non-skin dough sheet of surface side positioned at the non-skin of waistline pars contractilis
Load 60) it is then preferable.Skin dough sheet, waistline pars contractilis and non-skin dough sheet are engaged by joint portion.In skin dough sheet and
Both non-skin dough sheets are formed with the fold generated by joint portion row, and skin dough sheet can be inhibited to be stuck up in the end edge of diaper
Rise or non-skin dough sheet diaper end edge tilt situation.In addition, by with skin dough sheet, so as to improve
With the skin sense of touch in the face of the skin contact of infant.
1st region R1 is configured at then preferable from the region that leg pars contractilis extends along its length.Make in manufacture disposable urine
The elastic component that leg pars contractilis is constituted when cloth is extended with continuous state in product length direction, by the elastic structure of elongation state
Part, which is engaged in, knits piece (egative film, outer load etc.), after having manufactured disposable diaper non-individual body continuous in the longitudinal direction, according to
Each product length cuts off non-individual body along product width direction.Using the manufacturing method, by cutting off non-individual body, to extend
The elastic component of state is shunk in product length direction, and only residual joint is together in the part near leg-openings portion.In the manufacture
In method, it is being configured with leg pars contractilis from the region that leg pars contractilis extends along its length during fabrication, but under Product Status
Leg pars contractilis is not configured, the piece of knitting for clipping leg pars contractilis does not engage each other.
Due to being configured with the 1st relatively high region R1 of retractility (no from the region that leg pars contractilis extends along its length
With joint portion), therefore skin dough sheet and the non-unassembled region of skin dough sheet can be made to fit in body, the area can be inhibited
The leakage in domain, SAP self-absorption cores overflow.
5th region R5 and the 4th region R4 be located at lateral border than absorbent cores 40a by the inside of width direction position then compared with
It is good.The 1st region R1 for not having joint portion and arranging, tool are medially configured with towards width direction from the lateral border of waistline pars contractilis 85
There are joint portion the 3rd region R3 arranged, the 5th region R5 arranged without joint portion and the 4th region R4 arranged with joint portion.
Since the higher region of expansion and contraction and the lower region of expansion and contraction alternately configure, the wearer that excessively ties tight can inhibited
While improve stickiness.
More particularly, stickiness can be improved in the wearing of disposable diaper.When dressing disposable diaper, inciting somebody to action
In the state of disposable diaper expansion, the body of wearer is placed in the rear waist region of disposable diaper.At this point, wearer
Body is placed in a manner of the entire width for covering absorbent cores 40a.Wearer is positioned over absorbent cores 40a's in the body of wearer
Magic tape, front waist region to be fixed in are stretched in the state of entire width.At this point, leaning on width positioned at than absorbent cores 40a

4th region R4s and 5th region R5 of the domain R1 by the position of the inside of width direction are located at the lateral border than absorbent cores 40a and lean on width
Position on the inside of direction hardly extends in the direction of the width due to being applied with the body pressure of wearer.In the 3rd area
In the R3 of domain, the lateral border than absorbent cores 40a is not extended by the part of the inside of width direction, and the lateral border than absorbent cores 40a leans on
The part in the outside of width direction extends.Thus, the waistline of the state before just dressing disposable diaper and enabling a wearer to stand
For pars contractilis, the part elongation of the 1st region R1 and the 3rd region R3, the other parts of the 3rd region R3, the 4th region R4 and the
5 region R5 hardly extend.
When enabling a wearer to stand after having dressed disposable diaper, the body pressure that absorbent cores 40a applies is reduced.Cause
And the other parts, the 4th region R4 and the 5th region R5 of the 3rd region R3 become compared with the state before enabling a wearer to stand
It is easy to flexible.At this point, the 1st region R1 due to waistline pars contractilis has extended, and the 4th region R4 is compared with the 5th region R5
It is easy to extend, therefore the 4th region R4 is stretched and extended by the 5th region R5.As a result, the waistline for enabling a wearer to the state to stand is stretched
The 4th region R4 in contracting portion fits in the body of wearer with weaker power.In addition, same, the 3rd region R3 is also pasted with weaker power
Together in the body of wearer.Due to that equipped with the relatively low region in the relatively high region of expansion and contraction and expansion and contraction, can press down
It makes the while of excessively tying wearer tight and improves stickiness.
The central place configuration of 2nd region R2 across the width direction of disposable diaper is then preferable.In the back of wearer
The heart is configured with spine, and hemad is recessed compared with the position of left and right.The recessed position (michaelis's rhomboid) is lumbar vertebrae bone parts
Recess portion, the recessed position be configured with the 2nd region R2.It is configured at the recessed position of wearer and utilizes the 2nd region R2
The part of contraction.Thus, it is possible to inhibit the situation in the generation gap between the center and disposable diaper of the back of wearer, more
It is reliably prevented from the recessed position of back side and leaks.
The surface density at the joint portion of the 3rd region R3 is then preferable higher than the surface density at the joint portion of the 4th region R4.Due to the 3rd
The area at the joint portion of the per unit area in the R3 of region is more than the area at the joint portion of the per unit area in the 4th region R4,
Therefore the joint portion of the 3rd region R3 relatively closely configures compared with the 4th region R4.But due to the waistline pars contractilis in the 4th region
Elongation higher than the 3rd region waistline pars contractilis elongation, therefore the expansion and contraction of the waistline pars contractilis of the 4th region R4 is higher than
The expansion and contraction of the waistline pars contractilis of 3rd region R3.Have in the recess arrangement of the lumbar vertebrae bone parts of wearer and utilizes the 4th regions contract
Position.Thus, it is possible to inhibit the situation in the generation gap between the center and disposable diaper of the back of wearer, it is more reliable
Ground prevents from leaking from the recessed position of back side.

Enlarged plan view.In addition, in the disposable diaper of variation, structure identical with the disposable diaper of embodiment uses
Identical reference numeral simultaneously omits the description.The disposable diaper 10A of variation has multiple 3rd region R3 and multiple 5th regions
R5.Thus, in the end edge of disposable diaper, it is configured in order outward from the width direction center of disposable diaper
The 5th relatively high region R5 of the 4th relatively low region R4 of the expansion and contraction of waistline pars contractilis 85, expansion and contraction, expansion and contraction are relatively low
The 5th relatively high region R5 of 3rd region R3, expansion and contraction, expansion and contraction relatively low the 3rd region R3 and expansion and contraction are relatively high
1st region R1.
Using the disposable diaper of the variation, it can also be formed in the end edge of disposable diaper and be extended along its length
Fold, the situation for inhibiting the end edge of disposable diaper to tilt maintains the stickiness of back side.Further, since waist can be utilized
Enclosing pars contractilis makes bumps fit in body, therefore does not form the gap caused by bumps, can inhibit letting out for the back side of wearer
Leakage.In addition, the disposable diaper of variation configures on the extended line of the length direction of the elastic component 81 of leg side pars contractilis 80
There is the 5th region R5.Since joint portion is being not configured from the extended line that elastic component 81 extends along its length, manufacturing
When elastic component 81 do not utilize joint portion to be fixed, elastic component 81 can be configured with the state shunk in the longitudinal direction.
