Size adjustment band 12 includes a fixed portion 53 fixed through the joint 60 to the non-skin-facing surface of the chassis 11 in the center portion 20A of the front waist region 13, extending from the fixing portion 53 the outer edge 12a, to the 12b side and a pair of movable portions 54. Size adjustment band 12, the vertical axis are formed symmetrically with respect to P, 4 and 5, only described for the fixed portion 53 and the free portion 54 located on one side in the transverse direction X of size adjustment band 12 and that it has the same structure for the fixing portion 53 and the free portion 54 located on the other side. In this embodiment, the fixing unit 53 is constituted by a continuous sheet member connecting the pair of movable portions 54, for example, the sheet member forming the sizing band 12 is separated at the central portion 20A, the horizontal it may be configured to a pair of fixing portions 53 and the free portion 54 spaced in the direction X.

Free portion 54 was connected to the fixed portion 53, an elastically stretchable elastic part 58 (the lateral direction X in this embodiment) the length direction R, the outer edge 12a from the elastic part 58, 12b side and a gripper portion 57 (the outer end portion 54a) extending. Resilient portion 58, in between the fixed portion 53 and the gripper unit 57 may be at least partially elastically stretchable, it may be a configuration in which the whole is not stretchable elastically. Fixing portion 53 and the free portion 54, forms the outer shape of the size adjustment band 12 extends into a series in the longitudinal direction R, the belt-like sheet 64 which is formed from one or more sheet members, attached to the belt-like sheet 64 elastically and a band elastic body 63 to impart elasticity to the section 58. In this embodiment, the belt-like sheet 64, the inner sheet 61 facing the non-skin-facing surface of the chassis 11 are composed of outer sheet 62 which is positioned outer surface facing the inner sheet 61, the sheets 61, 62 are joined via their mutually facing hot melt adhesive applied to one surface (not shown). In the present embodiment, the "elastic unit 58" means the arrangement region of the band elastic body 63, does not mean an area where the shrinkage force acts. Accordingly, both side edges opposite side edges 12c of the size adjusting band 12 is positioned inward than 12d, the width W3 of the resilient portion 58 of the elastic portion 58 is smaller than the width W2 of the size adjustment band 12 ing.

Inner and outer sheets 61, 62 constituting the belt-like sheet 64, a known non-woven fabric, for example, the mass of about 10 ~ 40g / m 2, preferably, about 15 ~ 30g / m 2 spunbond nonwoven fabric, SMS nonwoven fabric It formed from and air-through fibrous nonwoven fabric. Band elastic body 63, extending in the longitudinal direction R, fineness from about 400 ~ 1200dtex, contracted or relaxed state from about 1.5 to 3.0 times the extended the plural rows of strings like or strand-like It is formed from an elastic material. However, the fineness and extension ratio of the elastic body can be changed according to the required contracting force and tensile stress. In this embodiment, the band elastic element 63 is arranged in a manner that expresses substantially no contractile force in the part of the fixed portion 53, the band elastic body 63 at the outer end portion 54a of the movable portions 54 are substantially are arranged in a manner that does not express the shrinkage force, the outer end portion 54a has a non-elastic. Incidentally, the band elastic body 63 may be configured not arranged on the fixed portion 53 and the outer end 54a. Further, a band elastic body 63 may be formed from a strip of elastic sheet, the belt-like sheet 64 made of an elastic sheet, the fixing portion 53 and the gripper unit 57 may process non elasticized.

The belt-like sheet 64 in gripper unit 57 is arranged tab sheet 57a formed of highly rigid fibrous nonwoven fabric or a plastic film relatively, the outer surface (the front waist region 13 opposed to the surface) of the tab sheet 57a is , fastening region 56 is disposed. Tab sheet 57a can gripper unit 57 is colored so that it can be distinguished from other areas. Fastening zone 56, hook group of the fastening possible mechanical fastener to the exterior sheet 32, 33 or the receiving portion disposed on their outer surfaces forming the outer surfaces of the front and rear waist regions 13, 14 (the loop group of mechanical fastener) having. Fastening region 56, in addition to the hook group mechanical fastener may be formed from a pressure sensitive adhesive.

The length (dimension in the lateral direction X) L1 size adjustment band 12 from about 500 ~ 600 mm, is formed to be almost equal to the dimension W1 in the lateral direction X in the front waist region 13 of the chassis 11. Further, the width dimension (dimension in the longitudinal direction Y) L2 of the front waist region 13 is about 0.99 ~ 250 mm, the width (dimension in the longitudinal direction Y) W2 sizing band 12 is about 20 ~ 100 mm. The length dimension L1 of the size adjusting band 12 may be longer or shorter than the dimension W1 of the chassis 11.

Referring to FIG. 4, the fastening region 56, both side edges 12c of the size adjusting band 12 extends in the longitudinal direction Y between the 12d, the width dimension is the same as the width W2 of the size adjusting band 12. Therefore, the width of the fastening zone 56, both side edges 12c, larger than the width W3 of the elastic portion 58 located at a distance from 12d inwardly, the end edges 56a, 56b are opposite side edges 58a of the elastic part 58 , it is positioned outside in the width direction S than 58b. Thus, both side edges 58a of the elastic part 58, both end edges 56a of the fastening region 56 than 58b, by 56b is located outside the width direction S, during the use of the sizing band 12, both side edges 12c, 12d can be prevented from turned up by the contraction action of the elastic portion 58.

Fastening zone 56 is in a state in which removal of the diaper 10 from the package, which is preferably secured to the non-skin-facing surface of the chassis 11 to form a front waist region 13. Moreover, during the manufacturing process of the diaper 10, a portion fastening zone 56 or gripper unit 57 is located may be temporarily fixed in advance in the non-skin-facing surface by heat sealing or the like of the chassis 11. Referring to FIG. 5, the diaper 10 is temporarily fixed to the chassis 11 via the joint zones 59 in the gripper unit 57. By thus fastening or tacking the fastening zone 56 and gripper unit 57, when not in use sizing band 12, the possibility that fastening zone 56 or irritate touch the body of the wearer It lost, and can prevent the Makureru resizable band 12 during transport of the diaper 10. Also, by relatively high rigidity tab sheet 57a is disposed on the gripper portion 57, easily operated for gripper the gripper unit 57, the operability as compared with the case where the tab sheet 57a is not disposed excellent. Further, in the outer end portion 54a of the movable portions 54, since the band elastic body 63 is disposed in a state that expresses substantially no contractile force, gripper portion 57 has a non-elastic. Accordingly, in a state where the fixed to the outer surface of the fastening region 56 of the rear waist region 14 or the crotch region 15 to pull the size adjustment band 12, contractile force of the band elastic body 63 to the fastening region 56, i.e., the fastening zone 56 never force tending to peel (force directed to the front) it acts directly and gripper portion 57 as compared with the case having elasticity is stably secured.

FIG. 6 (a), the (b), the example, a slender wearer when the waist and / or leg of the wearer slightly smaller than the corresponding dimensions of the diaper 10, the size adjustment when using a band 12, first, releasing the fastening by the fastening region 56 by pulling the gripper unit 57 pledged finger between the outer edge 12a, 12b of the side edge and size adjustment band 12 of the diaper 10 as to pull toward the outside of the diaper 10 (see the phantom line in FIG. 5). Next, the state where pulled by gripper the gripper unit 57, i.e., toward the fastening zone 56 by maintaining the state of being stretched elastic portion 58 to the rear waist region 14 (or crotch region 15) It pulled to secured to the outer surface. Thus, when pulled sizing band 12 rearward, the front end of the liquid-absorbent core 48 located in the fixed portion 53 are attracted to the rear, front both side portions 20B of the waist region 13 is shortened. That is, since the relatively high liquid-absorbent core 48 of rigid fastening area 56 in a state of being pulled to the rear is fastened to the rear waist region 14, a portion of the weak side portions 20B rigidity relatively are brought together, the dimension in the transverse direction X is reduced. Thereby, the size of the waist of the diaper 10 is decreased, it is fit to the waist of his or her small wearer. Further, by fastening the rear waist region 14 in a state where the elastic force of the elastic portion 58 to pull the size adjustment band 12 is worked, attract rearward central portion 20A to the position of the liquid-absorbent core 48 by a strong force it is possible to stably fit the body.

The size adjustment band 12, before because it is disposed in the crotch region 15 side of the waist region 13, by the central portion 20A to the position of the liquid-absorbent core 48 is attracted toward the rear, the leg openings 24 dimension be shortened, it is fit to the body of the wearer.

In this state, the size when the free portion of the adjusting band has no elasticity, when the posture of the wearer is changed, it is released fastening by fastening zone waist opening edge and the leg opening edge in a gap, especially when the wearer becomes recumbent state, which may cause side leakage of body fluid from the leg opening. In the diaper 10 according to the present invention, by the free portion 54 of the size adjustment band 12 has elasticity, caused by changes in the posture of the wearer, the force tries to release the fastening by fastening area 56 and the size adjustment band 12 to absorb forces (forces that generate torsion and bending) that tries to deform itself, can maintain the state of being fitted to the body opening edge even posture changes during wear. Furthermore, by positioning the elastic portion 58 to relatively wide range of the free portion 54, front in cooperation with the lower waist elastic region 37B and the lower rear waist elastic region 38B, the fit to the body of the diaper 10 it is possible to improve.

Also, pressing the fixing portion 53 of the size adjustment band 12 is positioned on the side edges of the absorbent core 48, side edges of the absorbent core 48 when pulled sizing band 12 rearwardly within the body since it is spread in the lateral direction X in the state that is, even gathers that decreases its absorbent in liquid-absorbent core 48 has been formed it is stretched, spread the liquid absorbing area it is possible to improve the liquid absorption properties. In particular, the size adjustment band 12, since the pair of movable portions 54 extend in opposite directions around the fixing portion 53, to pull the pair of movable portions 54 located on both sides 20B in opposite directions (right and left) since both side edges of the absorbent core 48 located in the fixing portion 53 is pulled to the right and left, whereas in comparison with the case where only the side edge portion is pulled backward, across more liquid-absorbent core 48 in the transverse direction X it can be expanded.

To achieve such an effect, it is preferable to be disposed in the leg opening 24 side in the waist region 13 before the size adjustment band 12, adjacent its side edges 12d of the front waist region 13 lower edge (both inner edges 18 d) or it is arranged so as to overlap it is more preferable. As already mentioned, by size adjustment band 12 is disposed in the leg opening 24 side, it becomes easy to fit the leg opening edge portion to the wearer's body, it is possible to prevent side leakage from the leg opening 24, in particular by positioned to the side edge 12d is close to or overlaps the lower edge of the front waist region 13, the size adjustment band 12 is closer to the leg opening 24, located between the leg openings 24 and the size adjustment band 12 chassis including ruffled-shaped portion 11, because the whole leg opening edge can be fit by the body.

In a state where the fastening band 56 of the size adjustment band 12 is fixed to the outer surface of the rear waist region 14, the side portions 21B of the waist region 14 after the position of the fastening region 56, the contracting action of the elastic part 58 since a force directed forward by, that the entire rear portion of the absorbent core 48 located in the central portion 21A of the rear waist region 14 is expanded in the lateral direction X, maintains its liquid-absorbing performance, improve can. Furthermore, when the fastening region 56 is positioned to overlap the side edges in a plan view of the rear end of the absorbent core 48, the rear end portion is pressed towards the body, positional displacement of the rear end portion it is possible to suppress.

Length direction R of the elastic part 58 of the size adjustment band 12, i.e. tensile stress N1 in the transverse direction X is preferably set higher than the tensile stress N2 in the transverse direction X of the front lower waist elastic region 37B. Further, (before and after) front lower waist elastic region 37B and in a worn state of the diaper 10 extension stress N3 in the transverse direction X of the lower waist elastic region 38B after the opposing, set higher than that of the lower front waist elastic region 37B it is preferred that. Specifically, tensile stress N1 of the elastic part 58 is 2.0 ~ 3.5 N, a tensile stress N2 before the lower waist elastic region 37B is 0.3 ~ 0.7 N, lower rear waist elastic tensile stress N3 of the band 38B is formed in the 1.2 ~ 2.6N. Tensile stress of the lower rear waist elastic region 38B and tensile stress N1 of the elastic part 58 is preferably set to the same extent, and the difference between the tensile stress N1, N3 is 0.1 ~ 1.0 N. In correlation with tensile stress N1 and tensile stress N2, by relatively tensile stress N2 is set low, easily passed through the legs leg openings 24 is relatively larger when wearing the diaper 10 becomes one, the elastic portions 58 having a high tensile stress N1 are fit the leg opening edge with the lower front waist elastic region 37B on the body than the tensile stress N2, it is possible to further improve the fit. Further, in the both side portions 20B, before when there is a large difference in stress in the tensile stress N3 Prefecture in the elastic region due to the tensile stress and the rear waist region 14 of the waist region 13, for example, have a higher tensile stress than the front the rear side If the diaper 10 becomes aspects pulled forwardly, the side edges of the diaper 10 which is positioned in the seam portion 22 is biased toward the front side, the entire diaper 10 is likely to cause positional deviation. Therefore, by setting the tensile stress N3 of the lower rear waist elastic region 38B and tensile stress N1 of at least the elastic portion 58 to the same extent, that balances the tensile stress of the waist in the front and rear, to obtain a stable Wearing it can.

In the wearing article having a normal size adjustable fastening tape, when the fastening tape has no elasticity, it never gathers on its outer surface is formed. Therefore, unity in appearance is impaired by located on the outer surface of the chassis a plurality of gathers are formed by the waist elastic member, and by the presence of the fastening tape, are disposable diaper rather than underwear it is easily recognized. Diaper 10 according to this embodiment, since the gathers of the elastic portion 58 on the outer surface of the sizing band 12 is formed with a plurality of the entire diaper 10 has a unity in appearance. In particular, by the string-like or strand-like elastic body plural rows like the waist elastic member is disposed in the elastic portion 58, as compared with the case where the elastic sheet is disposed, unity on more appearance it is possible to obtain. In this way, by having a sense of unity on the entire diaper 10 appearance, more satisfaction that underwear seems to have to wear a wearing article of pants-type is obtained, a spiritual support to live more active It may play a role in.
