The long continuous configuration in ground, and fixed with laterally elongated state.As a result, due to veutro band elastomeric element 35a, in upper zone
Domain AU substantially endlong assigns lateral retractility throughout lateral, which becomes the waistline opening 1HB's of diaper 1
Retractility.
It is overlapped in the lateral central portion ADc of lower area AD and is fixed with absorbent core 11 in absorbent main body 10 and deposited
Part 10p.In addition, each section ADe, ADe of the two sides positioned at above-mentioned central portion ADc in lower area AD, inhales
The property received main body 10 is not overlapped.
In addition, elastomeric element 35 is respectively throughout the lateral one end from part ADe in each section ADe, ADe
To substantially endlong continuously configuring for the other end, and fixed with laterally elongated state.As a result, in each section
In ADe, ADe, lateral retractility is substantially endlong assigned throughout lateral.
On the other hand, in above-mentioned central portion ADc, the transversely discontinuous configuration of elastomeric element 35.In detail, in this example
In, it is configured with the end of above-mentioned elastomeric element 35 in lateral both ends ADce, ADce of above-mentioned central portion ADc, and above-mentioned
Elastomeric element 35 is not present in the lateral center portion ADcc of central portion ADc, therefore, in above-mentioned central portion ADc, elastomeric element
35 transversely discontinuous configurations.Also, elastomeric element 35 is being not present in the center portion ADcc of central portion ADc like this
In the case of, retractility is hardly assigned in center portion ADcc, therefore, the lateral contraction of center portion ADcc is pressed down
System.In addition, being accompanied by this, the lateral contraction of absorbent core 11 is also suppressed, and therefore, also prevents the pleat of the absorbent core 11
The skin side of the generation of wrinkle, absorbent core 11 remains general planar.As a result, absorbent core 11 can be effectively prevented
Imbibition obstacle, be in addition also able to suppress the leakage of excreta caused by the generation because of fold.
In addition, in the present embodiment, configured with veutro band elasticity in the lateral both ends Adce of veutro tape member 30a
Configured with dorsal band elasticity in lateral both ends ADce of the lateral length Wa of the part of component 35a than back side tape member 30b
The lateral length Wb long of the part of component 35b.In other words, veutro is with the portion Chong Die with absorbent core 11 in elastomeric element 35a
The lateral length divided is longer than the lateral length of the part Chong Die with absorbent core 11 in dorsal band elastomeric element 35b.About this
The effect of the configuration of sample illustrates in aftermentioned Fig. 5.
In addition, as shown in figure 3, being arranged that be formed with animal etc. (not shown) in the above-mentioned central portion ADc of lower area AD
The inserting photograph 40 of illustration, is also suppressed according to the generation of reason same as described above, the fold of the inserting photograph 40.Illustration as a result,
It is readily seen that.
In addition, as shown in figure 3, being provided with post-processing adhesive tape 50 on the surface of the non-skin side of back side tape member 30b.After
Reason adhesive tape 50 is the component (adhesive tape component) of the elongated tape shape with bonding plane, using bonding plane as the shape of folded inside
State is fixed on back side tape member 30b.When discarding the diaper 1 after use, for so that absorbent main body 10 becomes inside
The post-processing adhesive tape 50 being folded is extended and winds the lateral diaper 1 of bonding plane by the diaper 1 of mode edge rolling along longitudinal direction, by
Diaper 1, can be remained the state of edge rolling by this.Thereby, it is possible to make the row for the inside (absorbent main body 10) for being attached to diaper 1
Object etc. is let out not discard diaper 1 with leaking out to outside.
Positional relationship > of the < about narrowed portion 11c and tape member side edge part
In the diaper 1 of present embodiment, by adjusting back side tape member 30b relative to absorbent main body 10 (especially
The narrowed portion 11c of absorbent core 11) bonding station, so as to make the leg and absorbent main body of wearer when diaper is worn
Gap is not likely to produce between 10 (absorbent cores 11).Hereinafter, being illustrated using comparative example.
Fig. 5 is the figure of the narrowed portion for illustrating the absorbent core 11 of present embodiment and the positional relationship of back side tape member 30b.
Fig. 6 is the figure of the narrowed portion for illustrating the absorbent core 11 of comparative example and the positional relationship of back side tape member 30b.
As described above, being connect in diaper 1 by veutro tape member side edge part 30ae and dorsal band component side edge part 30be
It closes, so that veutro tape member 30a and back side tape member 30b are shaped to ring-type, becomes the diaper of underwear type as shown in Figure 1.
At this point, being set to the veutro of veutro tape member 30a with elastomeric element 35a and the dorsal band elasticity for being set to back side tape member 30b
The state that component 35b links as the joint portion via tape member side edge part 30ae, 30be interacts with each other contractility.
Therefore, it in the waistline opening 1HB of diaper 1, is generated transversely by veutro band elastomeric element 35a and dorsal band elastomeric element 35b
Contractility.By the effect of the contractility, the waist close contact of be open 1HB and wearer are not easy diaper 1 when wearing
Dislocation.In addition, since veutro band elastomeric element 35a and dorsal band elastomeric element 35b respectively transversely draws absorbent main body 10
It drags, therefore, absorbent main body 10 expands width to lateral outer side, can cover to wide scope portion between the thigh of wearer.That is, logical
The engagement of veutro tape member side edge part 30ae Yu dorsal band component side edge part 30be are crossed, thus in the big of tape member 30a, 30b
The lateral contractility generated by veutro with elastomeric element 35a and dorsal band elastomeric element 35b is acted in range.
In addition, the absorbent core 11 of present embodiment passes through longitudinal middle part (veutro end 11a and back side in Fig. 5
Between the 11b of end) there is narrowed portion, to inhibit the both sides of the absorbent core 11 and the leg of wearer when wearing diaper 1
Interference, so that wearer is easy mobile leg.On the other hand, due to absorbent core 11 narrowed portion lateral width than veutro end
Portion 11a and back end 11b are narrow, and accordingly, there exist the regions narrow in the width, and asking for gap is generated between the leg of wearer
Topic.Also, if generating gap between the leg and absorbent core 11 of wearer, there is excretion to the excretion in absorbent core 11
A possibility that object is leaked out from the gap to outside.Especially, the case where wearing the infant of diaper 1 mostly with sleeping posture
Under, due to movements such as mobile legs, it is easy to generate gap in buttocks side.
In contrast to this, in the diaper of present embodiment 1, as shown in figure 5, dorsal band elastomeric element 35b pass through have with
The duplicate region narrowed portion 11c of absorbent core 11, so that the gap be made to be not likely to produce.In other words, dorsal band component side edge part
A part of 30be and the narrowed portion 11c position repetition in the longitudinal direction of absorbent core 11, so that gap be made to be not likely to produce.This be because
For for, with dorsal band component side edge part 30be duplicate region, making as described above in the narrowed portion 11c of absorbent core 11
With there is the lateral contractility generated by veutro with elastomeric element 35a and dorsal band elastomeric element 35b, by by the narrowed portion
11c is pulled to lateral outer side, so that narrowed portion 11c is easy to extending transversely.Therefore, it is suppressed that leg and absorption in wearer
Property core 11 between generate gap the case where.
On the other hand, as shown in fig. 6, in the diaper 1 of comparative example, the dorsal band component side edge part of back side tape member 30b
Position does not repeat the narrowed portion 11c of 30be and absorbent core 11 in the longitudinal direction.In this case, narrowing for absorbent core 11
Portion 11c does not act on the lateral contractility generated by veutro with elastomeric element 35a and dorsal band elastomeric element 35b, the narrowed portion
11c will not be pulled towards lateral outer side.Therefore, gap is still easy to produce between the leg of wearer and absorbent core 11.
Like this, in the present embodiment, by making at least part and absorbability of dorsal band component side edge part 30be
The narrowed portion 11c of core 11 is repeated in the longitudinal direction, to make to be generated by veutro band elastomeric element 35a and dorsal band elastomeric element 35b
Contractility act on narrowed portion 11c, the narrowed portion of absorbent core 11 can be made transversely to expand width.Thereby, it is possible to make
It obtains and is not likely to produce gap between the leg and absorbent core 11 of wearer.
In addition, veutro is not limited only to inhale with the region that the contractility of elastomeric element 35a and dorsal band elastomeric element 35b act on
The narrowed portion 11c of the property received core 11.In the case of fig. 5, also have and back side tape member in the back end 11b of absorbent core 11
A part of side edge part 30be duplicate region in the longitudinal direction.Therefore, transversely outer layback is also acted on for back end 11b
The power dragged.For example, due to defecation etc. and the buttocks side of absorbent core 11 become weight in the case where, by by back end 11b court
Lateral outer side (i.e. waistline direction) pulls, so that absorbent core 11 is not easy to misplace.In the present embodiment, dorsal band component lateral margin
The length of the repeat region in the longitudinal direction of portion 30be and absorbent core 11 is at least the longitudinal direction of dorsal band component side edge part 30be
More than the half (1/2) of length (referring to Fig. 5).By in the region of more than half of dorsal band component side edge part 30be and absorption
Property core 11 repeat, to be easy sufficiently effect with the contractility that elastomeric element 35a and dorsal band elastomeric element 35b are generated by veutro
In back side (buttocks side) region of absorbent core 11.
Other effect >s of the < about diaper 1
In diaper 1, (veutro is configured to dorsal band elastomeric element 35b with elastomeric element 35a): in the position of lower area AD
In the ADe (referring to Fig. 3) of lateral both sides, it is arranged in the transverse ends of absorbent main body 10 with elongated laterally state
Calf circumference elastomeric element 17 and calf circumference auxiliary elastic components 19 a part intersect.Herein, by veutro band elastomeric element 35a with
Longitudinal length in the region that calf circumference elastomeric element 17 and calf circumference auxiliary elastic components 19 intersect is as La.Similarly, by back side
Longitudinal length conduct with the region intersected with calf circumference elastomeric element 17 and calf circumference auxiliary elastic components 19 elastomeric element 35b
Lb。
In such intersection region, when wearing diaper 1, pass through calf circumference elastomeric element 17 and calf circumference auxiliary elastic components
19 to act on the power for pulling absorbent main body 10 along longitudinal direction, also, (veutro is with elastic portion by dorsal band elastomeric element 35b
Part 35a) act on the power for transversely pulling absorbent main body 10.That is, effect, which has, makes absorbent main body 10 (absorbent core 11)
The power that body relative to wearer is in close contact.
In addition, calf circumference elastomeric element 17 and calf circumference auxiliary elastic components 19 are not throughout the longitudinal of absorbent main body 10
It is configured with elongation state to whole region, but is configured in longitudinal defined region with stretched condition.In the elastomeric element
Longitudinally-contracted power is acted on absorbent main body 10, in the elastomeric element not to stretch in the region of elongation state configuration
In the region of long status configuration, longitudinally-contracted power is not acted on absorbent main body 10.In the present specification, this is received along longitudinal direction
The longitudinal length in the region of the power effect of contracting is also referred to as " the effectively length of calf circumference elastomeric element 17 and calf circumference auxiliary elastic components 19
Degree ".Calf circumference elastomeric element 17 and calf circumference auxiliary elastic components 19 are equivalent to the part that thick dashed line indicates in fig. 5 and fig.
Effective length.
As shown in fig. 6, in a comparative example, intersection region, that is, La length of veutro and intersection region, that is, Lb length of back side
It spends roughly equal.Specifically, the veutro band in the region La of Fig. 6 with the effective length partial intersection of calf circumference elastomeric element 17
Elastomeric element 35a be 7, in the region Lb of Fig. 6 with the dorsal band bullet of the effective length partial intersection of calf circumference elastomeric element 17
Property component 35b be 7.Therefore, in a comparative example, the effective of calf circumference elastomeric element 17 is acted on by dorsal band elastomeric element 35b
The power (power pulled towards lateral outer side) of length substantially evenly acts on.
In that case of comparative example, exists due to the mobile leg of the people for wearing diaper and cause in back side absorbability master
A possibility that fitness of body 10 (absorbent core 11) is deteriorated.In most cases, people is mainly mobile to front side (veutro) by leg, because
This, whenever the mobile leg of wearer, absorbent main body 10 (absorbent core 11) can all be pulled to front side (veutro), however, by
Veutro is constant with elastomeric element 35a (the dorsal band elastomeric element 35b) convergent force generated, so in the buttocks of wearer,
Compared with the power for pulling absorbent main body 10 (absorbent core 11) towards lateral outer side, it is more located towards the power that longitudinal veutro pulls
In ascendancy, absorbent main body 10 (absorbent core 11) is easy dislocation.In this case, when the back side change weight due to defecation etc.
When, a possibility that leakage there are excreta from the part that absorbent main body 10 (absorbent core 11) misplaces to outside.Especially, when
In the case that wearer is baby or child, diaper is worn with sleeping posture mostly, therefore, if the thigh of back side (buttocks side)
Between portion generate gap, then excreta be easy leak out.In addition, if absorbent main body 10 (absorbent core 11) back side towards transverse direction
The power that outside pulls is weak, then the end 10eb of absorbent main body 10 is easy towards lateral inside mistake whenever the mobile leg of wearer
Position, therefore, absorbent main body 10 (absorbent core 11), which is easy to roll, exposes buttocks.
In contrast to this, as shown in figure 5, in the present embodiment, the friendship of intersection region, that is, Lb length of back side than veutro
It is long to pitch region, that is, La length.In other words, in elongated laterally in calf circumference elastomeric element 17 (calf circumference auxiliary elastic components 19)
State the region that intersects with dorsal band elastomeric element 35b of part (effective length) than (the calf circumference auxiliary of calf circumference elastomeric element 17
Elastomeric element 19) in the area that intersects with veutro with elastomeric element 35a of part (effective length) in elongated laterally state
Domain is big.Specifically, in the region La of Fig. 5 with the veutro of the effective length partial intersection of calf circumference elastomeric element 17 band elastic portion
Part 35a be 7, in contrast to this, in the region Lb of Fig. 6 with the dorsal band of the effective length partial intersection of calf circumference elastomeric element 17
Elastomeric element 35b is 10, more than 7.Therefore, absorbent main body 10 (absorbent core 11) and calf circumference elastomeric element 17 are by back side
The power pulled with elastomeric element 35b towards lateral outer side is bigger than the power pulled with elastomeric element 35a towards lateral outer side by veutro.By
This can be improved the fitness of back side in the diaper 1 of present embodiment.
Also, in the present embodiment, effective length of the back side of calf circumference elastomeric element 17 (calf circumference auxiliary elastic components 19)
Degree is at least 1/2 or more of the longitudinal length of dorsal band component side edge part 30be.In Fig. 5, the back side of calf circumference elastomeric element 17
Effective length Lb be dorsal band component side edge part 30be longitudinal length more than half.In dorsal band component side edge part 30be
Region, after veutro tape member 30a and back side tape member 30b are shaped to ring-type, effect by veutro band elastomeric element 35a and
The lateral drag force that dorsal band elastomeric element 35b is generated, so by making in this region and 17 (calf circumference of calf circumference elastomeric element
Auxiliary elastic components 19) range intersected becomes larger, so that the fitness of diaper 1 can be further increased by said effect.
In addition, in the diaper 1 of present embodiment, by make veutro in elastomeric element 35a with 11 weight of absorbent core
Lateral length Wb of the lateral length Wa of folded part than the part Chong Die with absorbent core 11 in dorsal band elastomeric element 35b
Long (referring to Fig. 5), so as to adjust the intensity for the power that absorbent core 11 is pulled towards lateral outer side.Elastomeric element and absorbability
The part that core 11 is overlapped is longer, and absorbent core 11 is more strongly pulled by the elastomeric element towards lateral outer side, therefore, such as this implementation
As mode, by making dorsal band elastomeric element 35b and the lap of absorbent core 11 shorten, to make to inhale in back side
The property received core 11 is not become too strong towards the power that lateral outer side pulls directly.The fit of the absorbent main body 10 of buttocks is maintained as a result,
Sense, and a little space is formed between buttocks and absorbent core 11, it is held in the space while the just indiffusion being drained can be made
In.On the other hand, by making absorbent core 11 directly becoming strong towards the power that lateral outer side pulls in veutro, to make absorbent core
11 are in close contact with body, are able to suppress the leakage for the urine being drained.
In addition, each elastomeric element is arranged in the diaper 1 of present embodiment: dorsal band elastomeric element 35b transversely stretches
Contractility when contractility when contracting is stretched along longitudinal direction than calf circumference elastomeric element 17 or calf circumference auxiliary elastic components 19 is strong.That is, each
Elastomeric element is configured to: being made with when calf circumference elastomeric element 17 and calf circumference auxiliary elastic components 19 are fitted in absorbent main body 10
Calf circumference elastomeric element 17 is compared with the ratio that calf circumference auxiliary elastic components 19 extend, and is fitted in by dorsal band elastomeric element 35b
The ratio for extending dorsal band elastomeric element 35b when back side tape member 30b is bigger.Make 10 (absorbent core of absorbent main body as a result,
11) act on stronger towards the power that lateral outer side extends, so in seat area of wearer etc. by 10 (absorbability of absorbent main body
Core 11) towards horizontal expansion width, it is easy to inhibit the leakage of excreta.
In addition, being able to suppress makes stern due to post-processing adhesive tape 50 when wearing diaper in the diaper 1 of present embodiment
The skin contact of portion side generates the case where sense of discomfort.In diaper 1, dorsal band elastomeric element 35b and calf circumference elastomeric element 17 are handed over
Longitudinal length La of the longitudinal length Lb in the region of fork than veutro with the region intersected with calf circumference elastomeric element 17 elastomeric element 35a
It is long.That is, back side tape member 30b and the longitudinal overlapping portion of absorbent main body 10 are big.It is fixed on back side tape member 30b as a result,
Non-skin side surface post-processing adhesive tape 50 position be easy (reference Chong Die with the position of absorbent core 11 in a thickness direction
Fig. 3).In other words, post-processing adhesive tape 50 and absorbent core 11 are configured at the duplicate position of at least part in the longitudinal direction.Wearer
When wearing diaper 1, have due to existing in a thickness direction between the skin of wearer (buttocks) and post-processing adhesive tape 50
The absorbent core 11 of thickness, therefore, the absorbent core 11 play a role as cushion, post-process the sense of touch of adhesive tape 50 as a result,
It is not easy to pass to the skin (buttocks) of wearer, it is suppressed that the generation of sense of discomfort.
