Then, as shown in Figure 6B, there is the linear seam S of longitudinal ingredient to be formed to make the band-like abdomen in elongation state The a part of of continuous elastic component 350 in side exterior member 300 cross-section opens.By cutting band-like skin lateral plate 310, continuous bullet Property component 350 and band-like non-skin lateral plate 320 formed seam S.Specifically, by using predetermined cutter (including laser knife etc. Contactless cutter) in band-like skin lateral plate 310 and band-like non-skin lateral plate 320 form the notch that penetrates through on thickness direction simultaneously And cutting continuous elastic component 350, to form seam S.Fig. 6 B is shown at the time of seam S (notch) has been formed.Then, institute The seam S of formation is generated by the effect of the contractility of continuous elastic component 350 such as the through-hole 50 in Fig. 6 C.

Fig. 7 is an exemplary schematic side elevational for showing the through-hole for carrying out through-hole formation process and forming device 500 Figure.Through-hole forms device 500 and includes anvil roller 510, cuts roller 520 and auxiliary transmission roller 530.Anvil roller 510 is around pivot center The barrel tumbler (rotor) of rotation, and there is unshowned aspirating mechanism in its circumferential surface.Then, it anvil roller 510 and is sucked solid Fixed band-like veutro exterior member 300 (band-like back side exterior member 400) on the circumferential face rotates together, so that outside band-like veutro Dress component 300 (band-like back side exterior member 400) is transmitted in rotation direction.Anvil block 511 is set to the circumferential surface of anvil roller 510. Anvil block 511 is long component on the axis direction (with crisscross corresponding in Fig. 5) of anvil roller 510.In addition, cutting roller 520 It is to be arranged in the rotor of the position faced with anvil roller 510, and be provided on the circumferential surface for cutting roller 520 along cutting roller 520 axis direction (with crisscross corresponding) cuts block 521.Then, it while anvil roller 510 rotates, cuts roller 520 and exists It is rotated in opposite direction, so that anvil block 511 and cutting block 521 and being in their periodically relationships facing with each other.Cut block 521 In be provided with cut away section along axis direction (crisscross), and when the anvil block 511 of cut away section and anvil roller 510 is facing with each other And when contact substrate, the seam S with the ingredient of crisscross (longitudinal direction) is formed in the substrate.Auxiliary transmission roller 530 is set to anvil Upstream and downstream on the conveying direction of roller 510 is applied to the tension for the band-like veutro exterior member 300 transmitted with adjusting Size, while band-like veutro exterior member 300 being helped to transmit along the circumferential surface of anvil roller 510.Constant be applied in the transmission Power reduces the generation of the displacement of seam S.

Note that through-hole, which forms device 500, can have the function of cutting a part of continuous elastic component 350,450.Fig. 2 Elastic component 35,45 is shown in the region of the central portion in the close transverse direction Chong Die with absorber 11 of elastic component 35,45 not Continuously, to prevent stretch/shrink power from acting on the region, and in this region, 500 company of cutting of device is formed by through-hole Continuous elastic component 350,450.In this case, have cut with the elastic component for cutting 53 identical function of roller roller 540 setting exist (referring to Fig. 7) at the position of anvil roller 510, make it possible to accurately cut continuous elastic component 350,450.This makes it possible to Implement the process to form the process of through-hole 50 He cut a part of continuous elastic component 350,450 with same apparatus, makes it possible to Compact manufacturing equipment is constructed, enough so as to efficiently manufacture diaper 1.Note that can be in transmission direction (transverse direction) A position at cut continuous elastic component 350,450, or continuous elastic component 350,450 is cut at multiple positions.

Seam S according to the present embodiment is linear seam and can only be formed by being cut in the material.Thus, It is different from the case where cutting the shape with predetermined area in traditional diaper manufacture process, it is not easy to generate chip.Thus, As shown in figure 5, this chip of processing can not be separately provided when being continuously manufactured by diaper 1 in the case where transmitting substrate Process in the case where formed through-hole 50.Furthermore, it is suppressed that manufacturing equipment (such as through-hole of diaper 1 is interfered because generating chip Form device 500) normal operating and/or reduce the failure of manufacturing equipment.This makes it possible to improve the productivity of diaper 1, And it is further reduced the manufacturing cost of diaper 1 and the maintenance cost of manufacturing equipment.

Fig. 6 C shows a part of the veutro exterior member 30 when wearer wears diaper 1.In veutro exterior member 30 Through-hole 50 is formed in a manner of opening its profile towards the two sides in transverse direction generally rhomboidal in shape when diaper is worn. This is because as shown in Figure 6 C, elastic component 35 shrinks horizontally to pull around through-hole 50.Then, through-hole 50 exists It is significantly opened when diaper is worn, so as to enhance the gas permeability of diaper 1.It is each single by more greatly opening Through-hole 50 can ensure the gas permeability of diaper 1 with the through-hole 50 of lesser amt.In addition, even at the shape put on before diaper State also can horizontally open through-hole 50 by the elastic component 35 in contraction state, and this makes to help such as baby Deng wearer put on the caregiver etc. of diaper 1 and can be visually observed through-hole 50 and recognize the improvement of gas permeability.

In addition, the elastic component 35 shunk pulls the non-woven fabrics around through-hole 50, to form the wheel along through-hole 50 Wide fold.These folds can soften the quality of diaper 1.Particularly, in the case where foring through-hole using predetermined notch, Through-hole is opened in the case where general planar around it.However, in the present embodiment, due to being formed using threadiness seam S Through-hole 50, so rising to form fold around through-hole 50 by the non-woven fabrics that the hole opened pulls.This makes it possible to Improve the quality of diaper 1.

The through-hole 50 of back side exterior member 40 is formed in a manner of identical with the through-hole 50 of veutro exterior member 30.Note that In the present embodiment, it is contemplated that be separately formed the through-hole 50 of back side exterior member 40 and the through-hole 50 of veutro exterior member 30 The case where make an explanation, but not limited to this.Veutro exterior member 30, back side exterior member 40 (S106) can be integrally formed Veutro exterior member 30 and back side exterior member 40 is set to separate (S107) later with through-hole 50.

By the details of the construction of the through-hole 50 formed in the diaper 1 of explanation according to the present embodiment.As shown in Fig. 2, veutro The through-hole 50 of exterior member 30 is set to not set return portion 32f, sheet element 34 and absorbability in veutro exterior member 30 The region of main body 10.Specifically, through-hole 50 is set in the longitudinal direction on the lower and than the lower end of sheet element 34 on the lower than end 30e The region of side, and it is set to the outside of absorbent main body 10 horizontally.In addition, through-hole 50 is relative to the center in transverse direction The symmetrical mode of A-A is configured at side and the other side in the transverse direction of veutro exterior member 30.

In addition, through-hole 50 is arranged at the upside elastic component 35t's positioned at longitudinal top side of veutro exterior member 30 Downside, and it is arranged at the upside of the lower side elastic component 35u positioned at the lower side of veutro elastic component 30.Continuous elastic Part due to through-hole 50 component 35m and side elastic component 35s is discontinuous.This is because as described above, when forming through-hole 50, Continuous elastic component 350 is cut together with band-like skin lateral plate 310 and band-like skin lateral plate 320.Upside elastic component 35t and Lower side elastic component 35u is not discontinuous because of through-hole 50.

In the present embodiment, it is arranged in a staggered fashion through-hole 50.Fig. 8 is the enlarged drawing for showing the part B in Fig. 2. Fig. 8 is shown：Through-hole 50a (first through hole)；Through-hole 50b (the second through-hole) is located at the left oblique upper of through-hole 50a and vertical It is adjacent with through-hole 50a upwards；Through-hole 50c (third through-hole), positioned at through-hole 50a upside and horizontally with through-hole 50a Overlapping；And through-hole 50d, the left side and be overlapped in the longitudinal direction with through-hole 50a in the transverse direction of through-hole 50a.In addition, bullet Property component 35a (First elastic component) and through-hole 50a and through-hole 50d are be overlapped in the longitudinal direction, similarly, elastic component 35b (second Elastic component) it is Chong Die with through-hole 50b in the longitudinal direction, elastic component 35c (3rd elastic component) is heavy with through-hole 50c in the longitudinal direction It is folded.In the longitudinal direction, elastic component 35d is set below through-hole 50a, and elastic component 35e is arranged at through-hole 50a and through-hole Between 50b, elastic component f is arranged between through-hole 50b and through-hole 50c.Elastic component 35d, 35e, 35f in the longitudinal direction not with Any through-hole 50 is overlapped.Note that elastic component 35c is corresponding with continuous elastic component 35m, elastic component 35a, 35b, 35e, 35f Corresponding with side elastic component 35s, elastic component 35d is corresponding with lower side elastic component 35u.

As shown in figure 8, such through-hole 50 have it is generally rhomboidal in shape, the inside of through-hole 50 is penetrated through to non-skin side.This When, the cutting end on vertex and elastic component 35 in transverse direction generally rhomboidal in shape is respectively at roughly the same position.Then, The not set inside in through-hole 50 of the elastic component 35 being cut, and the elastic component 35 being cut at through-hole 50 It is discontinuous in transverse direction.This is because the elastic component 35 at the position for forming through-hole 50 is arranged in by one when forming through-hole 50 It rises and cuts.Thus, for example, elastic component 35a is from the outside in the transverse direction of through-hole 50a continuously to outer in the transverse direction of through-hole 50d Side, and the not set inside in through-hole 50a and through-hole 50d.Similarly, elastic component 35b is not disposed in through-hole 50b, and And elastic component 35c is also not disposed in through-hole 50c.

In addition, by along it is lateral while g and along longitudinal while h external through-hole 50 surrounded rectangular area (by Fig. 8 In slave upper right towards lower-left the part that indicates of oblique line) in not set bonding agent etc..In the present embodiment, using being coated on The bonding agent of elastic component 35 engages skin lateral plate 31 and non-skin lateral plate 32.

In addition, in the present embodiment, each through-hole 50 has a roughly the same size, and along longitudinal direction, through-hole 50a and Through-hole 50c horizontally overlaps each other.Then, L1 is greater than L2 (L1 > L2), wherein L1 is lower end and the through-hole 50c of through-hole 50a Lower end between longitudinal distance, L2 is the longitudinal length of through-hole 50.

L3 be less than L2 (L3 < L2), wherein L3 be because of through-hole 50 discontinuous elastic component in the longitudinal direction with this not Continuous elastic component is adjacent and the not longitudinal length because of through-hole 50 between discontinuous elastic component, and L2 is through-hole 50 Length.For example, the distance between elastic component 35a and elastic component 35e L3 are less than the longitudinal length L2 of through-hole 50.

In addition, how the manufacturing method of diaper 1 according to the present embodiment, can form seam S according to basis as described below To change the shape of through-hole 50 and the configuration of elastic component 35 Chong Die with through-hole 50 in the longitudinal direction.

Fig. 9 is the figure for illustrating the through-hole 50a formed when stitching S and shifting in the longitudinal direction.In Fig. 9, by form seam S When make to stitch S form through-hole 50a than elastic component 35a a part of longer mode on the lower cutting.That is, by from Elastic component 35a, the center energy of through-hole 50a in the longitudinal direction are cut at the position that the longitudinal center of seam S is deviateed Enough easily from the displacement of elastic component 35a.In the case where Fig. 9, in the longitudinal direction, from the upside vertex of through-hole 50a ( Hereinafter, also referred to as upper end et) to elastic component 35a distance Lu be less than from the downside vertex of through-hole 50a (hereinafter, Also referred to as lower end eb) arrive elastic component 35a distance Ld.That is, the longitudinal center C of through-hole 50a locates in the longitudinal direction In the position than elastic component 35a on the lower, and through-hole 50a has relative to longitudinal asymmetrically shape.Note that Fig. 9 shows Through-hole 50a is gone out, however, it is also possible to similarly form other through-holes 50 (for example, through-hole using the seam S shifted in the longitudinal direction 50b, through-hole 50c).In this case, distance Lu and Ld can be different from the situation in Fig. 9.That is, displacement in the longitudinal direction can To change with through-hole 50.

Figure 10 is the through-hole 50a for illustrating to be formed when stitching S relative to longitudinal inclination at a predetermined angle.In Figure 10, work as shape When at seam S, so as to stitch the cross-section elastic component 35a of center C (continuous elastic component 350) of S and seam S relative to longitudinal direction with angle (outside in transverse direction in Figure 10) inclined mode forms notch to degree θ to the right, to form through-hole 50a.This makes vertical 's the position of side in the transverse direction of through-hole 50a can upwards easily moved from the position of the other side in the transverse direction of through-hole 50a Position.In case of fig. 10, during the lateral right-hand end er (hereinafter, also referred to as right end er) of through-hole 50 is located in the longitudinal direction The downside of heart position C.This is because in the profile of through-hole 50a, the length between upper end et and right end er be equal to lower end eb with Length between right end er and the formation isosceles triangle using right end er as vertex, and according to the inclination of seam S, right end er is located at The downside of center C.Then, since right end er is displaced to the downside of center C, so the cutting end of elastic component 35a The position at (that is, the end for being located at the side through-hole 50a) is also displaced to the downside of center C in the longitudinal direction.For the same reason, lead to The lateral left-hand end el (hereinafter, also referred to as left end el) of hole 50a is located at the upside of center C in the longitudinal direction.Then, Since the displacement of left end el is to the upside of center C, so the cutting end of elastic component 35a is (positioned at the side through-hole 50a End) position the upside of center C is also displaced on longitudinal direction in Figure 10.

As a result, through-hole 50a be formed as in Figure 10 relative to longitudinal direction with the diamond shape of angle Cl so that vertical The position of the left end el of upward through-hole 50 is different from the position of right end er.In Figure 10, in the longitudinal direction, the left end el of through-hole 50a Position deviate from d50a from the position of right end er.Thus, it is arranged in the position of the elastic component 35a of the both lateral sides of through-hole 50a It sets and has offset with one another d50a in the longitudinal direction.In addition, according to the bias d50a generated in the longitudinal direction, the position of the upper end et of through-hole 50 It sets and horizontally deviates from w50a from the position of lower end eb.Then, through-hole 50a has relative to the asymmetric shape of vertical and horizontal Shape.

Note that Figure 10 shows through-hole 50a, however, it is possible to similarly be formed in a manner of stitching S relative to fore-and-aft tilt other Through-hole 50 (for example, through-hole 50b, through-hole 50c).In this case, the tilt angle theta for stitching S can change with each seam S.That is, longitudinal On bias d50a and transverse direction on bias w50a can change with each through-hole 50.

In the diaper 1 of manufacturing method manufacture according to the present embodiment, it can utilize from skin side and penetrate into non-skin The through-hole 50 of side improves gas permeability, and is cut using elastic component 35 to adjust the tension of elastic component 35.

For example, by through-hole 50a be overlapped in the longitudinal direction with elastic component 35 in fig. 8 and through-hole 50d the case where progress Explanation.Elastic component 35a and elastic component 35e is the elastic component of identical material, and in seam S (through-hole 50a and through-hole 50d) Before formation, elastic component 35a and elastic component 35e are engaged and fixed to 31 He of skin lateral plate under same elongation state Non-skin lateral plate 32.Elastic component 35a is cut off using seam S (through-hole 50a and through-hole 50d), any seam S is not utilized to cut off elastic structure Part 35e.Then, tension Ta1 is less than tension Te (Ta1 < Te), wherein Te is bullet adjacent with elastic component 35a in the longitudinal direction Property component 35e tension horizontally size, Ta1 be from the left side (center side) of through-hole 50d to elastic component 35a with inhale The size of the tension of the elastic component 35a for the position setting that acceptor 11 is overlapped in a thickness direction horizontally.Similarly, tension Ta2 is less than tension Te (Ta2 < Te) and tension Ta2 again smaller than tension Ta1 (Ta2 < Ta1), wherein Ta2 be located at through-hole 50d with The size of the tension horizontally of elastic component 35a between through-hole 50a.

In addition, because through-hole 50a, 50d etc. keep elastic component 35a discontinuous, thus work as and be applied on vertical and horizontal When power, compared with the continuous situation of elastic component, elastic component 35a can more freely stretch.That is, continuous with elastic component Situation is compared, the elastic component positioned at the elastic component 35a in the left side of through-hole 50d and between through-hole 50a and through-hole 50d 35a can more freely stretch according to movement so that diaper 1 be not only easier to follow the movement in transverse direction be also easier to follow it is vertical Upward movement.This can improve the abdomen of diaper 1 and the stickiness of buttocks.

Therefore, it is provided with and utilizes the elastic components 35 of one or more seam S (one or more through-holes 50) cuttings and unfavorable The elastic component 35 cut off with one or more seams S (one or more through-holes 50), so as to adjust of elastic component 35 Power makes it possible to enhance the stickiness of diaper 1 to inhibit excessively to fasten in waist while ensuring to fasten in waist.

In addition, the center C for stitching S can be shifted from elastic component 35 in the longitudinal direction when the formation of through-hole 50.In the feelings Under condition, as shown in figure 9, the position of the center C of through-hole 50 (through-hole 50a) and elastic component 35 (elastic component 35a) is vertical It is different upwards, make it possible to be formed as through-hole 50 relative to longitudinal asymmetrically shape.Then, because being set to around through-hole 50 Non-woven fabrics region (downside of Fig. 9 elastic member 35a) of the fold around the downside of through-hole 50 that constitutes of rise than existing Region (the long side of Fig. 9 elastic member 35a) around the upside of through-hole 50 is formed much.For example, working as veutro exterior member 30 When (for example, before diaper 1 is worn) state of elongation changes into the state that veutro exterior member 30 hardly extends, in through-hole The top (end of fold in a thickness direction) of the fold formed around the downside of 50a is to the interior inclination of the horizontal line of through-hole 50a ?.As a result, even if can also make the downside of through-hole 50 seem smaller in appearance when through-hole 50 is significantly opened.This It can reduce the worry that wearer and/or caregiver etc. may leak excreta etc. from through-hole, while improving gas permeability.Note Meaning can suitably change the center of through-hole 50a (seam S) center C in the longitudinal direction and elastic component 35a, and The center of through-hole 50a in the longitudinal direction is not necessarily arranged in the downside of the center of elastic component 35a.Through-hole 50a exists Longitudinal center C can be arranged in the upside of the center of elastic component 35a.

Furthermore it is possible to be formed in through-hole 50 by the center C for changing through-hole 50 shift amount in the longitudinal direction to change The shape and size of the fold of surrounding.For example, making vertical between the center C of first through hole 50a and First elastic component 35a Longitudinal shift amount between the center C and second elastic component 35b of upward shift amount and the second through-hole 50b is each other It is different.Then, the shape of fold for being formed in the shape and size of the fold around through-hole 50a and being formed in around through-hole 50b Become different from each other with size, the gas permeability of diaper 1 is freely adjusted so as to the setting position according to through-hole 50a, 50b And/or appearance.

In addition, seam S can be tilted at a predetermined angle relative to longitudinal when forming through-hole 50.In this case, such as Figure 10 Shown, the position and the position of right end er of the left end el of through-hole 50 (through-hole 50a) is different in the longitudinal direction, so as to make through-hole 50 Relative to vertical and horizontal asymmetry.Then, it is arranged to the longitudinal direction of the elastic component 35a be overlapped in the longitudinal direction with through-hole 50a On position it is also different between the two sides of through-hole 50a.When wearer's its mobile body in the case where wearing diaper 1, abdomen Side exterior member 30 is deformed into be folded in the longitudinal direction in a manner of being used as baseline along the position of the elastic component 35 of lateral arrangement. That is, elastic component 35 is used as folding base when diaper 1 folds in the longitudinal direction.Thus, such as in Figure 10, in the cross of through-hole 50 The position of elastic component 35 in the longitudinal direction is (in case of fig. 10, d50a indicates bias) different from each other at upward two sides, Enabling the baseline for folding in the longitudinal direction (not have the case where deviateing in the longitudinal direction) from one increases to Liang Chu (vertical There is the case where deviation upwards).Then, veutro exterior member 30 is subtly folded in the longitudinal direction, is worn so that diaper 1 is easy to follow The movement of the body of user and deform, so as to improve stickiness.

Then, the longitudinal position of elastic component 35 is deviateed at the two sides in the transverse direction of through-hole 50, to inhibit The elastic component that threadiness extends to grow in transverse direction is left a trace on the skin of wearer.In addition, the position of aforementioned tension Ta1 effect Set it is different from each other in the longitudinal direction with the position of tension Ta2 effect, to make to act in the up and down direction and left and right directions of through-hole 50 Different power, so that the shape of the fold being formed in around through-hole 50 becomes asymmetric up and down.Thus, non-woven fabrics is logical Rise (fold) in the outer edge in hole 50 irregularly, and hardly forms big and long fold.Thus, it is possible to inhibit Apply on local pressure and/or the skin for inhibiting the trace of fold to stay in wearer on the skin of wearer when wearing diaper 1, So as to further improve quality.

In addition, in the example in Figure 10, outside inclination of the through-hole 50 in transverse direction.In this case, in the longitudinal direction, through-hole 50 left end el (inner end in transverse direction) is higher than the center C of through-hole 50, and right end el (outboard end in transverse direction) is lower than The center C of through-hole 50.That is, elastic component 35 is lower than elastic component 35 in through-hole 50 in the position of the right end er of through-hole 50 The position of left end el.In the case where such through-hole 50 is configured as horizontally identical position arrangement, adjacent to each other Two through-holes 50 between elastic structure 35 relative to lateral inclination.For example, in fig. 8, horizontally through-hole 50a adjacent to each other Between through-hole 50d, elastic component 35a is tilted upwards from the left end el of right end er towards the through-hole 50a of through-hole 50d.Thus, In veutro exterior member 30 (back side exterior member 40), applied from the crotch side of wearer (horizontally by elastic component 35a Inside and downside in the longitudinal direction) (outside horizontally and upside in the longitudinal direction) effect obliquely convergent force.Then, In diaper 1, the elastic component 35 be overlapped in the longitudinal direction with through-hole 50 (that is, by elastic component 35 that through-hole 50 is cut off) is from wearing The crotch skew back of person applies convergent force upward.Using the convergent force, absorbent main body 10 is pulled simultaneously to longitudinal upside By the outside broadening in transverse direction, so that absorbent main body 10 is easy fitting body when diaper 1 is worn.

In addition, can be made relative to longitudinal tilt angle theta lateral the two of through-hole 50 by changing in through-hole 50 Longitudinal bias d50 at end is different.For example, making longitudinal bias d50a in first through hole 50a and Longitudinal bias d50b in two through-hole 50b is different from each other.Then, make the shape for the fold being formed in around through-hole 50a And size and the shape and size for the fold being formed in around through-hole 50b it is different from each other, further make through elastic component 35a The direction of the tension of application and the direction of the tension applied by elastic component 35b are different from each other.Thus, it is possible to according to through-hole The aforementioned folding base of setting position change and quality of 50a, 50b, so as to freely adjust the stickiness of diaper 1.

In addition, in the example in Figure 10, the position of the upper end et of through-hole 50 and the position of lower end eb are horizontally inclined each other From w50, so as to improve stickiness.In diaper 1, elastic component 35 is horizontally shunk, in veutro exterior member 30 In along being longitudinally formed longitudinal fold.If the upper end et and lower end eb of through-hole 50 are horizontally overlapped, longitudinal fold is easy to form In the straight line for penetrating through upper end et and lower end eb in the longitudinal direction, the upper end for making it easy to be formed from veutro exterior member 30 is long to lower end Macrofold.In this case, when diaper 1 is worn, fold is pressed against the skin of wearer, makes it easy to leave on the skin The trace of such fold.However, in the diaper 1 manufactured in the present embodiment, due to the upper end et and lower end eb of through-hole 50 It is laterally offset from, so longitudinal fold is opened in the upper side and lower side disjunction of through-hole 50, so that compared with afore-mentioned hardly Form macrofold.Further, since horizontally forming several tiny longitudinal folds side by side, make diaper in cross so longitudinal fold is used as The baseline being folded up deforms diaper 1 according to the movement of wearer.Thus, it is possible to improve the fitting of diaper 1 Property.

In addition, as shown in Figure 9 and Figure 10, as long as through-hole 50 has relative at least one of horizontal and vertical asymmetry Shape, it will be able to keep each through-hole 50 eye-catching, so as to improve visuality.Thus, user can be to being set to veutro exterior The through-hole 50 (blow vent) of component 30 is very clear, and securely by diaper 1 through with wearer.Further, since through-hole 50 shape is asymmetric, so the fold being formed in around through-hole 50 also becomes asymmetric, makes it possible to improve in diaper 1 Quality when being worn.

Note that showing in Fig. 8 into Figure 10 in any case, the width in the transverse direction of each through-hole 50 can be different.Example Such as, in the transverse direction in left end el between right end er at a distance from for the through-hole 50a (first through hole) and through-hole 50b (in Fig. 8 Two through-holes) it can be different.Using such construction, it is different with each region in veutro exterior member 30 to be capable of forming shape Through-hole 50, so as to improve the design and beauty of diaper 1.

Similarly, the opening area of each through-hole 50 can be different.For example, the area of opening portion can be made (that is, diamond shape Area) it is different between through-hole 50a (first through hole) and through-hole 50b (the second through-hole) in fig. 8.Utilize such construction, energy Enough region setting large opening areas and small opening area according in veutro exterior member 30, it is thus possible to for example be held by increasing Opening area around the leg easily perspired and/or back side adjusts the permeability of through-hole 50.Thus, it is possible to inhibit in diaper 1 generates humidity etc. when being worn, to hardly cause the sense of discomfort as caused by the wearing of diaper.

Then, even if the opening area of through-hole 50 and/or shape are different, if the length of seam S be it is constant, through-hole 50 Outer peripheral length (perimeter of through-hole 50) is exactly constant.In other words, in through-hole 50, between upper end et and left end el away from From the distance between the distance between, left end el and lower end eb, lower end eb and right end er between right end er and upper end et away from From total value be constant.For example, in fig. 8, the outer peripheral perimeter of first through hole 50a is equal to the outside of the second through-hole 50b The perimeter of edge.That is, the length of part to be cut is constant in material (for example, non-woven fabrics), to make in through-hole 50 Strength Changes around through-hole 50 are smaller.Then, even if horizontally or longitudinally being pulled up when diaper 1 is worn When dynamic veutro exterior member 30, also hardly cause that specific region (around particular via 50) is easy to tear this is asked Topic makes it possible to ensure that the whole intensity of diaper 1.

In addition, transverse ends el, er and elastic component 35 of through-hole 50 are in diaper 1 according to the present embodiment The position being overlapped in the longitudinal direction is in by the cutting end cut off seam S (positioned at the end of through-hole side).Then, by elastic component 35 to Outside horizontally pulls transverse ends el, er of through-hole 50 so that through-hole 50 be formed with left end el, right end er, The diamond shape of upper end et and lower end these vertex eb.Then, it is ensured that enough gas permeabilities, and beautiful diamond shape quilt It is arranged as arranging in the surface of veutro exterior member 30, so as to improve the appearance of diaper 1.In addition, elastic component 35 is cut The broken ends of fractured bone is in the position in the outside in the transverse direction of transverse ends el, er of through-hole 50, so that cutting end does not protrude into through-hole 50. That is, the cutting end due to elastic component 35 is horizontally prominent not from the inward at both ends side of through-hole 50, so inhibiting elastic structure The cutting end of part 35 is when diaper 1 is worn and the direct skin contact of wearer, so that wearer does not feel good hardly.
