It is characterised by, the front side exterior body 12F in the mode shown in Fig. 5, Fig. 7, Fig. 8 and rear side exterior body 12B Fixed in the following manner: outside formation the sheet material of lamella 12S between crotch the end of side in inside piece layer 12H Turn back and form the part 20 of turning back of side between part 20, and this crotch of turning back of side between crotch and do not open in side.Therefore, front side is exterior The gap 12i side between crotch between display sheet 25 and inner side lamella 12H in body 12F and rear side exterior body 12B End is closed by sheet material, therefore reliably prevent this gap 12i side opening between crotch.Result is, the most reliably Prevent following situation: due to the gap 12i side opening between crotch between display sheet 25 and inner side lamella 12H, lead Cause aesthetic property to deteriorate or inner side lamella 12H and the outside lamella 12S stripping of exterior body 12F, 12B, or in order to disappear The excess resilient extensible member 18 cut off except retractility exposes from opening or drops out outside from opening.It addition, If making outside lamella 12S turn back to the inner side of inside piece layer 12H and form side return portion between crotch as which Divide 20, then the part of turning back of outside lamella 12S will not be exposed at diaper outer surface, therefore, it is possible to prevent institute of turning back The deterioration of the aesthetic property caused, on the contrary, it is also possible to mode as shown in figure 11 uses such structure like that: make shape Inside one-tenth, turn back in the sheet material of lamella 12H outside of the end of side lamella 12S laterally between crotch.

Between crotch side turn back part 20 fixed structure without particular limitation of, can in the way of as shown in Figure 5 like that by crotch between side Part of turning back 20 is fixed by fixing at interior outer fixing portion 201, it is also possible to utilize the fixing of other parts It is fixed, alternatively, it is also possible to part 20 of being turned back side between crotch as shown in Figure 7 is fixed on via hot-melt adhesive Opposed faces.As the hermetic unit represented with label 21 in fig. 8, it is also possible to by heat-sealing or ultrasonic sealing etc. Means based on material welding part 20 of being turned back side between crotch seals together with the part of main body of turning back.

The outside lamella 12S of exterior body 12F and rear side exterior body 12B on front side of a sheet material by sharing is formed In the case of the lamella 12H of inner side, such mode can be formed as in the way of as shown in Figure 9 and Figure 10 like that: Utilize part and the part in outside of the inner side of the sheet material turned back in the edge of side between crotch, exterior on front side of formation respectively The inner side lamella 12H and outside lamella 12S of body 12F and rear side exterior body 12B.In such manner, front side The gap 12i between display sheet 25 and inner side lamella 12H in exterior body 12F and rear side exterior body 12B is also at crotch Between the end of side closed by sheet material, the most also reliably prevent this gap 12i side opening between crotch.

Furthermore it is also possible to mode as shown in figure 12 is formed as such mode like that: exterior body 12F on front side of formation And the sheet material of the inner side lamella 12H in rear side exterior body 12B and outside being formed the sheet material of lamella 12S all between crotch The end of side laterally (or, it is also possible to inner side) turn back, form side between crotch and turn back part 20.Such Under mode, in front side exterior body 12F and rear side exterior body 12B display sheet 25 and inner side lamella 12H between Gap 12i is closed by sheet material the end of side between crotch, therefore reliably prevent this gap 12i side opening between crotch.

According to above-mentioned various modes, can suitably determine to turn back the length of turning back of part 20 in side between crotch, remove Can be set as outside about 5～30mm the shortest parts, it is also possible to mode as shown in Figure 9 and Figure 10 that Sample is set as the degree identical with direction length before and after the exterior body with this part of turning back.

As it has been described above, in this utility model, the gap 12i between display sheet 25 and inner side lamella 12H is difficult to Side opening between crotch, therefore, it is possible to make display sheet 25 extend between the crotch of front side exterior body 12F and rear side exterior body 12B The end of side such that it is able to guarantee to show that area is bigger.Therefore, it is possible to by display sheet 25 crotch between side edge, Separate between the edge of side with between the crotch of the front side exterior body 12F with this display sheet 25 and rear side exterior body 12B Distance 25e is set as about 5～30mm.

As it was previously stated, preferably mode is: only on the width of non-telescoping region A1, position performs use In formed non-telescoping region A1 the cut-out to elastic flexible component 15,16,19, thus, as Figure 14 (a), Shown in Figure 14 (b), excess resilient extensible member 18 is only cut by the elastic flexible component continuous print with stretching region A2 Remainder of having no progeny is constituted.In this case, have an advantage in that cut-out vestige 22 tails off, it is not easy to because cutting off Vestige 22 overlap waits and is difficult to see that the display of display sheet 25.Particularly, as shown in Figure 14 (b), if non- Beyond the width central authorities of stretching region A1 perform for formed non-telescoping region A1 to elastic flexible component 15, 16, the cut-out of 19, then cut off the position of vestige 22 beyond central authorities, it is not easy to hinder the display of display sheet 25, Therefore it is preferred.In this case, although connect with the elastic flexible component of stretching region A2 of width side Continuous excess resilient extensible member 18 remains longer, but, due between display sheet 25 and inner side lamella 12H Gap 12i be difficult to side opening between crotch, thus without becoming problem.

(other)

In the above example, the both sides at front side exterior body 12F and rear side exterior body 12B are both provided with side folding between crotch Return part 20, it is also possible to only any one party arrange side between crotch turn back part 20 (also include such situation: although Both sides at front side exterior body 12F and rear side exterior body 12B have display sheet 25, but only a side are applied this reality Structure with novel).
