<enclosing portion about skirt>
Next, illustrating that skirt encloses the specific structure and function in portion.As described above, rear side skirt enclose the structure of portion 40s with
It is roughly the same that front side skirt encloses portion 30s, therefore only encloses portion 30s to front side skirt below and be illustrated, and omits and encloses portion 40s about rear side skirt
Detailed description.
Approximate vertical view when Fig. 5 is from diaper 1 under front side (veutro) observation of nature state.In addition, " nature "
Refer to the state after diaper 1 to be placed to the predetermined time.For example, by the front side band member 30 of diaper 1 and rear side band member 40 to cross
Two upward outside drawings, are set as " elongation state " for band member 30,40, after keeping the elongation state for 15 seconds, release urine
The drawing of cloth 1 and be placed on desk etc. plane on.Then, 5 points will be have passed through in the state that such plane is laid flat
The state of clock is set as nature.
As shown in figure 5, in diaper 1, it is in front side band member 30, than front side joint portion 51 before longitudinal downside
Side skirt encloses portion 30s to longitudinal downside and is outer expandable in transverse direction, encloses such wheel to make diaper 1 integrally and become skirt
It is wide.This is because the front side skirt of longitudinal lower end in front side band member 30 encloses portion 30s, since the bullets such as rubber band are not configured
Property component 35, therefore, it is difficult to shrink in the transverse direction, on the other hand, longitudinal upper end in front side band member 30 is in elastic component 35
It becomes easy and shrinks in the transverse direction under effect.That is, central portion of the diaper 1 at least transverse direction, in front side, skirt encloses portion 30s and has along vertical
To the low elasticity region LER with scheduled width (for example, length L30s in Fig. 4), the upper end of band member 30 in front side,
Have high resiliency region HER in the region with scheduled width as described above (referring to Fig. 2).Moreover, it is low to act on this
Tension in the transverse direction of Hookean region LER is less than the tension in the transverse direction for acting on high resiliency region HER.Thus, before being formed in
The front side skirt of the lower end of side band member 30 encloses portion 30s and is difficult to shrink in the transverse direction compared to the upper end of front side band member 30, holds
Easily being formed naturally skirt as Fig. 5 encloses shape.
The size of " tension " that acts in the transverse direction in each region can measure as follows.Firstly, in nature
In front side band member 30 under state, the sheet element of reinforcement is engaged in the end of the side in transverse direction using bonding agent etc.
The skin side (or being also possible to non-skin side) in the region between center in (such as left-hand end) and transverse direction.It connects down
Come, central location horizontally, in the range longer than the longitudinal length of high resiliency region HER (such as the length of L30s × 2
Degree) in cut out along longitudinal notch, cutting front side band member 30 and elastic component 35.Then, due to elastic component 35 be intended to from
Outside (end of side) of the center (position of notch) in transverse direction in transverse direction is shunk, therefore with the position of notch not from cross
Using stretching, measuring appliance etc. catches reinforcement sheet element to the mobile mode in upward central location and application overcomes elastic component 35
To the power of cross-direction shrinkage.At this point, the power that obtained using stretching measuring appliance measurement can be sized in present embodiment
The size of " tension ".The size of tension also can be similarly measured low elasticity region LER.
According to this structure, can make constitute diaper 1 component in, front side band member 30 part simply as
Front side skirt encloses portion 30s and functions.That is, not needing to form skirt and enclose and be arranged relative to 30 independent structures of front side band member
Part, or do not need to be enclosed as skirt and function and carry out special processing and (add for example, being used to form the cutting that skirt encloses
Work, engagement processing etc.).Thus, it is possible to be implemented without, complicated processing, to be able to suppress enclosing with skirt for manufacturing cost disposable
Diaper.
In addition, in the diaper 1 of present embodiment, due in the entire not set elastic component of low elasticity region LER (elasticity
Component 35), therefore it is essentially a zero to act on the tension that front side skirt encloses in the transverse direction of portion 30s.Therefore, with high resiliency region HER it
Between the difference of tension become larger, front side skirt encloses portion 30s and is easy largely to extend as shown in Figure 5.In addition, due to tension be difficult into
Row effect, therefore when wearing diaper 1, front side skirt encloses the easy movement with the body of wearer of portion 30s cooperatively freely
It deforms, it is difficult to enable a wearer to generate sense of discomfort, unplessantness displeasure.
In the diaper 1 of present embodiment, it is following to enclose the satisfaction of shape when portion 30s is extended for front side skirt in its natural state
Condition.That is, enclosing portion 30s's in Fig. 5 with the lower end 30ewb and front side skirt of shortest distance connection lateral margin joint portion 30ew
As longitudinal lower end and be outboard end in transverse direction the straight line and longitudinal angulation of endpoint 30sebs in, if will
Biggish angle is set as θ 30s, then 180 degree >=30s >=90 degree θ.And, it is preferred that 30s >=100 degree 140 degree >=θ.If θ
30s is greater than 180 degree (140 degree), then front side skirt, which encloses portion 30s, becomes the state of closure, if opposite θ 30s is less than 90 degree (100
Degree), then front side skirt, which encloses portion 30s, becomes the state rolled.In contrast, if the size of θ 30s is in above-mentioned range,
Skirt beautiful in appearance can be formed to enclose, it is difficult to generate damage design, lovely degree such problems.
In addition, in the case where front side skirt, which encloses portion 30s, to deform freely, when wearing diaper 1, it is possible to preceding
The entirety that side skirt encloses portion 30s is rolled, it is difficult to play the function of enclosing as skirt.However, in diaper 1, by adjusting front side engagement
Positional relationship between portion 51 and lateral margin joint portion 30ew, the entirety for being easy that front side skirt is inhibited to enclose portion 30s are rolled.Fig. 6 is to preceding
Relationship between side engagement portion 51 and rear side joint portion 52 and lateral margin joint portion 30ew and lateral margin joint portion 40ew is said
Bright figure.The Fig. 6 indicates the state that diaper 1 is unfolded and has been extended in the same manner as Fig. 2.Fig. 7 is to the front side in diaper 1
The top view that the state that the part that skirt encloses portion 30s has been rolled is indicated.
When wearing diaper 1, in front side, skirt encloses when portion 30s rolls, the feelings that the free end of transverse ends first is rolled
Condition is more.Front side skirt is shown in FIG. 7 and encloses the state that left-hand end (endpoint 30sebs) upward direction of portion 30s has been rolled.Separately
Outside, when the left-hand end that skirt encloses portion 30s in front side is rolled, the lateral margin for being rolled up to the left side of band member 30 on front side of being formed in first is connect
The position of the lower end 30ewb of conjunction portion 30ew.Then, as the left-hand end pull-up being rolled-up, front side skirt encloses rolling for portion 30s
It is gradually transmitted to the right (center side) from the left side (outside) in transverse direction.However, in diaper 1, as shown in fig. 6, in longitudinal direction
On, the position of the lower end 51eb at front side joint portion 51 is lower than the position of the lower end 30ewb of lateral margin joint portion 30ew.As a result, in cross
The front side skirt that upward left-hand end is rolls-up onto the height of lower end 30ewb encloses portion 30s can only be rolls-up onto height at front side joint portion 51
Spend the position of the lower end 51eb lower than the height of lower end 30ewb.That is, using the front side joint portion 51 for being set to lateral center portion, suppression
It has made front side skirt and has enclosed the rolling to lateral transport of portion 30s.In other words, make to produce in lateral side (left end of Fig. 7)
It has given birth in the case that front side skirt encloses the rolling of portion 30s, skirt encloses portion 30s on front side of the other side (right-hand end of Fig. 7) horizontally
Also it is difficult to roll.Thus, the entirety for being easy that front side skirt is inhibited to enclose portion 30s is rolled.
In the diaper 1 of present embodiment, the lower end of the lower end 51eb and lateral margin joint portion 30ew at front side joint portion 51
Relationship between 30ewb meets condition below.That is, for the front side band member 30 under elongation state as shown in Figure 6,
The straight line and transverse direction of the lower end 30ewb of the lower end 51eb at joint portion 51 and lateral margin joint portion 30ew on front side of being linked with the shortest distance
In angulation, if lesser angle is set as θ 51eb, 51eb >=5 degree 45 degree >=θ.And, it is preferred that 30 degree >=
51eb >=10 degree θ.If the height substantially phase between the position and lower end 30ewb of less than 5 degree of θ 51eb (10 degree), lower end 51eb
Deng, it is difficult to inhibit what skirt enclosed to roll to lateral transport.On the other hand, if θ 51eb is greater than 45 degree (30 degree), lateral margin joint portion
The lower end position 30ewb of 30ew is got higher, and lateral margin joint portion 30ew can not be formed with size appropriate, it is possible to lead to bond strength
It is insufficient.In addition, the lower end position 51eb at front side joint portion 51 is lower, it is possible to cause front side skirt to enclose portion 30s and be difficult to ensure and fill
The area divided.As long as the construction of diaper 1 would not be made to generate and asked in contrast, the size of θ 51eb is in above-mentioned range
Topic can effectively inhibit front side skirt and enclose rolling for portion 30s.
In addition, in common disposable diaper, sometimes through using the means such as printing absorbent main body outer packing
Additional pattern, decorative pattern improve design on (being equivalent to back sheet member 15).If enclosing skirt set on such diaper, having can
The pattern for being additional to absorbent main body, decorative pattern can be caused to be enclosed by the skirt hiding, design is deteriorated.In particular, if the institute as above of diaper 1
Stating, which becomes front side skirt, encloses the construction that portion 30s is difficult to roll, then the decorative pattern etc. of absorbent main body 10 is difficult to be seen.Therefore, it is urinating
In cloth 1, when from the non-skin side from thickness direction, portion 30s can be enclosed through front side skirt and see absorbent main body 10.Change speech
It, the part that skirt encloses portion 30s in front side and absorbent main body 10 is overlapped in a thickness direction can penetrate low elasticity region LER
See absorbent main body 10.Even if being also able to suppress the design of diaper 1 in the case where enclosing portion 30s equipped with front side skirt as a result,
It is deteriorated.
Specifically, in diaper 1, by making the light transmittance of low elasticity region LER than the light transmission of high resiliency region HER
Rate is big, sees absorbent main body 10 to readily penetrate through front side skirt and enclose portion 30s.In addition, the measurement of light transmittance can for example utilize
It is measured by test method of standard etc. of JIS Z8722.According to this structure, in low elasticity region, LER is readily penetrated through
Front side skirt, which encloses portion 30s, sees absorbent main body 10.On the other hand, in high resiliency region, HER is difficult to see through front side band member 30
See absorbent main body 10.If being set as that front side band member can be penetrated in the high resiliency region HER being set near waist opening
30 see absorbent main body 10, it is likely that make the uneasiness of user (wearer) generation as follows: being easy effect when wearing
There is the sheet element of the waist opening portion of biggish power relatively thin, whether diaper 1 can be damaged.In contrast, in diaper 1, due to height
The translucency of Hookean region HER is lower, it is difficult to see absorbent main body 10, therefore be not easy that user etc. is made to generate uneasiness.
In addition, in diaper 1, the quantity of the component (sheet element) being laminated in a thickness direction in the LER of low elasticity region
Less than the quantity of the component (sheet element) being laminated in a thickness direction in the HER of high resiliency region.Specifically, low elasticity area
The component being laminated in a thickness direction in domain LER (front side skirt encloses portion 30s) is non-woven fabrics 31,32 this two, in contrast, high
The component being laminated in a thickness direction in Hookean region HER is non-woven fabrics 31,32, sheet element 38 and front side folded-back part 32f
This four.As a result, since the relationship of above-mentioned translucency is easy to set up, also, the stacking of the sheet element of low elasticity region LER
Number is less, therefore skirt encloses portion and is easy to deform freely.Thus, front side skirt encloses portion 30s and easily becomes the ruffle shape to wave, energy
Enough impression for causing to enclose closer to skirt to user (wearer).On the other hand, due in high resiliency region HER, sheet element
Stacking number is more, therefore is easy to ensure sufficient intensity in waist opening portion, it is difficult to it is damaged in this way to generate the diaper 1 when wearing
The problem of.
Also, in diaper 1, make apparent design in low elasticity region LER and high resiliency region HER difference.Scheming
In 1 example, in high resiliency region HER, front side band member 30 is plain color, in contrast, in low elasticity region LER (front side skirt
Enclose portion 30s), undulatory decorative pattern is added to the surface of front side band member 30.As noted previously, as in low elasticity region LER
Tension is difficult to act on, therefore is additional to front side skirt and encloses the decorative pattern etc. of portion 30s and be difficult to shrink, and design is not easy to be deteriorated.As a result, can
Enough improve is set to the front side skirt of diaper 1 and encloses the design of portion 30s, also, enables a wearer to easily identify the front side skirt and enclose portion 30s.
In addition, both can change face as the method for keeping apparent design different with high resiliency region HER in low elasticity region LER
Color, or cotton ginning processing is implemented to the part of non-woven fabrics, it is also possible to other methods.
In addition, the lower end 30eb of the front side band member 30 of diaper 1 be formed with illustrate as in Fig. 4 it is such without glue side
Edge.That is, being not provided with bonding agent in the part that front side skirt encloses the bottom (lower end 30eb) of portion 30s, non-woven fabrics 31 and 32 does not connect mutually
It closes.Thus, in front side, skirt encloses the bottom part of portion 30s, is separately extended by non-woven fabrics 31 and 32, becomes ruffle stacking
Such shape, the appearance that skirt can be made to enclose it is more likable.Moreover, the non-woven fabrics 31 and 32 being laminated in a thickness direction
Be not interconnected, thus front side skirt enclose the bottom (lower end 30eb) of portion 30s skin sense of touch it is softer.The bottom part be
Higher position (referring to Fig.1 etc.) when wearing diaper 1 and a possibility that the leg of wearer contacts, therefore by becoming ruffle shape
Soft skin sense of touch, can make wearing feeling good.
In addition, in the longitudinal direction, the position of the lower end of non-woven fabrics 31 and the position of the lower end of non-woven fabrics 32 can also be made to be staggered.
For example, in the longitudinal direction, keeping the lower end position of the non-woven fabrics 32 of skin side lower than the lower end position of the non-woven fabrics 31 of non-skin side.It is logical
It crosses and does so, when from outside, it is easier to identify that the lit-par-lit structure of non-woven fabrics 31 and 32, the duplex of ruffle become
It is obvious, therefore can more improve the apparent lovely degree of diaper 1.
Alternatively, it is also possible on the longitudinal direction without glue edge that front side skirt encloses that portion 30s and rear side skirt enclose portion 40s change lower end
Width (length).That is, front side skirt can also be made to enclose the interval between the lower end 30eb of portion 30s and the lower end at joint portion 37
It is different that the length of LD30 encloses the interval length of LD40 between the lower end 40eb of portion 40s and the lower end at joint portion 47 from rear side skirt.
By doing so, shape, the size for the hem part that skirt can be made to enclose are different before and after diaper 1, therefore can more improve
The design of diaper 1, functionality.For example, the interval LD40 ratio front side skirt without glue edge for making rear side skirt enclose portion 40s encloses portion 30s
The interval LD30 long without glue edge.In this case, front side becomes the lesser simple design of ruffle, can be difficult when wearing
To interfere the movement of the leg of wearer.On the other hand, it can cover on a large scale wearer's using biggish ruffle in rear side
Buttocks side.
In addition, in diaper 1, the length of length and rear side band member 40 in the longitudinal direction of front side band member 30 in the longitudinal direction
It is equal.According to such construction, the material of identical size can be used in front side band member 30 and rear side band member 40, therefore made
It makes process to become simple, additionally is able to inhibit lower by manufacturing cost.On the other hand, in front side band member 30 and rear side band member
In the case that 40 are identical size, face shaping is approximate before and after diaper 1, and therefore, it is difficult to judge the front and back of diaper 1, it is possible to
Lead to the case where front and back is worn with getting wrong when wearing etc..In contrast, if changing before and after diaper 1 as described above
The size (length at no glue edge) for becoming the hem part that skirt encloses can then make the appearance of diaper 1 in front and back difference, therefore in addition to mentioning
Except the design of high diaper 1, user (wearer) is also made to easily determine the front and back of diaper 1.
But for diaper 1, the length centainly made front side band member 30 in the longitudinal direction and rear side band member are not needed
40 length in the longitudinal direction is identical.For example, it is also possible to by making the length ratio front side band member of rear side band member 40 in the longitudinal direction
30 length in the longitudinal direction is long and is set as enclosing longer design in the buttocks side skirt of wearer.
It is in multiple elastic components 35 for configuring in a row in the longitudinal direction, lower side in addition, for front side band member 30
Elastic component 35b is configured at the position of the lower end 30ewb high than lateral margin joint portion 30ew in the longitudinal direction (referring to Fig. 2).The elasticity
Component 35b is the elastic component for being configured at the position that portion 30s is enclosed near front side skirt in the longitudinal direction.That is, front side skirt encloses
Portion 30s is most susceptible to the influence of the tension in the transverse direction generated by elastic component 35b.However, as described above, in diaper 1
On longitudinal direction, the upper end of portion 30s is enclosed (that is, front side connects than front side skirt in the position of the lower end 30ewb of lateral margin joint portion 30ew
The lower end 51eb in conjunction portion 51) position it is high, the position of lower end 30ewb of the position than lateral margin joint portion 30ew of elastic component 35b
It sets and more increases.Therefore, the tension in transverse direction generated by elastic component 35b is difficult in the whole region that front side skirt encloses portion 30s
It impacts, front side skirt, which encloses portion 30s, to deform freely, easily become the shape extended with waving.
In addition, front side skirt under natural conditions encloses the position of the lower end 30eb of portion 30s (front side band member 30) in height side
It is leaned on upwards than the lower end position of diaper 1 (position for the substantially central portion C10 being equivalent on the length direction of absorbent main body 10)
Upside.That is, as shown in Figure 1, shown in Figure 5, in diaper 1 in its natural state, absorbent main body 10 is not enclosed by front side skirt
Portion 30s is completely covered, and the lower crotch of absorbent main body 10 becomes the state that at least part is exposed.Moreover, absorbent main body
10 lower crotch exposes, thus allow user (wearer) it can be seen that leg-openings 1HL at least part.Exist as a result,
It is easy the position of confirmation leg-openings 1HL when wearing diaper 1, is able to suppress the leg when the leg of wearer is by leg-openings 1HL
By jam.
In addition, in diaper 1, set on the calf circumference elastic component 17 (and calf circumference secondary resilient members 19) of calf circumference rivel LG
With part Chong Die with front side joint portion 51 in a thickness direction (referring to Fig. 2).Calf circumference elastic component 17, which shows, makes absorbability
The power that alongst (that is longitudinal) shrinks of main body 10.If front side skirt encloses portion 30s as shown in Figure 7 in this state
It is crimped to upside, then front side skirt is enclosed into portion 30s and worked to the power that longitudinal upside pulls.Then, in calf circumference elastic component
Under the action of 17 convergent force, front side skirt is pulled to longitudinal downside by front side joint portion 51 and encloses portion 30s.That is,
The convergent force of calf circumference elastic component 17 is acted on as the reaction force that front side skirt is enclosed the power that portion 30s is rolled to upside, will
Front side skirt encloses portion 30s and is easy to be cancelled to the power that upside pulls.Thereby, it is possible to be easy that front side skirt is inhibited to enclose rolling for portion 30s.
<variation>
The lower end 30ewb of lower end 51eb and lateral margin joint portion 30ew in Fig. 6 to front side joint portion 51 is in the longitudinal direction
Positional relationship is illustrated, but can also deform as follows to the relationship.Fig. 8 is the variation to diaper 1
Relationship between front side joint portion 51 and rear side joint portion 52 and lateral margin joint portion 30ew and lateral margin joint portion 40ew carries out
The figure of explanation.Fig. 9 is front side skirt in the variation to diaper 1 bowing of enclosing that the state that the part of portion 30s has been rolled is indicated
View.
As shown in figure 8, in the longitudinal direction, the position of the lower end 51eb at front side joint portion 51 is high in the diaper 1 of variation
In the position of the lower end 30ewb of lateral margin joint portion 30ew.Other structures are roughly the same with above-mentioned diaper 1.
In the diaper 1 of variation, in front side, skirt encloses when portion 30s rolls, with Fig. 7 the case where in the same manner as, front side first
The free end that skirt encloses the transverse ends of portion 30s is rolls-up onto the position of the lower end 30ewb of lateral margin joint portion 30ew.Show in Fig. 9
Go out front side skirt and encloses the state that the left-hand end upward direction of portion 30s has been rolled.Then, seemingly as the left-hand end pull-up that has been rolled-up
, front side skirt encloses rolling from the left side in transverse direction for portion 30s and gradually transmits to the right.At this point, the lower end at front side joint portion 51
The position 51eb is higher than the lower end position 30ewb of lateral margin joint portion 30ew, therefore front side skirt encloses portion 30s and is difficult to be rolls-up onto front side and connects
The height of the lower end 51eb in conjunction portion 51.Thus, in this variation, even if in the case where front side skirt encloses portion 30s and rolled, it will
The front side skirt encloses portion 30s and is also difficult to act on front side joint portion 51 to the power of longitudinal upside pull-up.That is, even if Yu Qian
Side skirt is enclosed in the case that portion 30s produces and roll, it is also difficult to remove the engagement between absorbent main body 10 and front side band member 30.
Such structure front side joint portion 51 it is smaller, be difficult to forcefully remain engaged with intensity in the case where especially effectively, for example, energy
Enough it is applied to the small size diaper etc. of infant.
