Furthermore same as outer sheet 52 above-mentioned, inner sheet 53 more extends length side compared with leakage prevention sheet 51 to 3 side of lower crotch To, and the lower ora terminalis 51b of leakage prevention sheet 51 is subject to coating.If illustrate, in the lateral area 45 of rear side coupling member 40B Junction 45a on, inner sheet 53 have extend beyond leakage prevention sheet 51 lower ora terminalis 51b lower extension 53b.Such as preceding institute It states, outer sheet 52 also has lower extension 52b.Accordingly, there exist the lower extension 53b for having inner sheet 53 and outer sheet 52 The region of lower extension 52b overlappings, and in this region, both lower extension 52b, 53b are engaged with each other.About inner sheet 53 lower extension 53b, as long as the entire length P of the junction 45a to lateral area 45₂, positioned at junction 45a's The length R of the length Q2 of leakage prevention sheet 51 and the lower extension 53b of inner sheet 53₂It is set as journey identical as outer sheet 52 above-mentioned Degree.

(the 2nd change case)

Then, illustrate the 2nd change case in relation to disposable diaper of the present invention with reference to Fig. 9.In addition, rear body 2 described herein as The construction of side is also applied for 1 side of predecessor.As shown in figure 9, in rear side coupling member 40B, other than the composition that Fig. 6 illustrates, also have There is inner face leakage prevention sheet 54.Inner face leakage prevention sheet 54 is the opaque liquid sheet element towards skin face for being fitted in leakage prevention sheet 51.As The sheet element with 51 same story of aforementioned leakage prevention sheet can be used in inner face leakage prevention sheet 54.It is leakage prevention sheet 51, outer in example shown in Fig. 9 The upper edge of dough sheet 52 and inner face leakage prevention sheet 54 is in flush state.Moreover, in the example, under leakage prevention sheet 51 and outer sheet 52 Ora terminalis is also in flushing state.But its lower ora terminalis side can be made to reach and be engaged in absorption though the length of inner face leakage prevention sheet 54 has Property ontology 30 not face skin face degree, be but short compared with leakage prevention sheet 51 and outer sheet 52.

In addition, compared with shown in fig. 6 constitute, structurally not phase of the example shown in Fig. 9 in absorbability ontology 30 Together.Also that is, in this example embodiment, the tergite 33 that absorbability ontology 30 has does not reach the end of the length direction of absorbability ontology 30 Edge.The ora terminalis 33a of the length direction of tergite 33 is not bonded on top flat 32, and is engaged in the not face skin of absorber 31 Face.But cover plate 34 then reaches the ora terminalis of the length direction of absorbability ontology 33, and is engaged in the length direction end of top flat 32. In this way, in example shown in Fig. 9, the not face skin face of absorber 33 is not coating by tergite 33, and has been intentionally formed not Region 33b with tergite.This does not have region 33b of tergite because without the poor tergite 33 of aeration and flexibility, therefore can Say that its aeration is excellent, and flexibility is higher.

According to above-mentioned composition, even if being formed with the not face skin of absorber 33 in the length direction end of absorbability ontology 30 Face is not by the coating region 33b without tergite of tergite 33, but in the example of figure 9, by leakage prevention sheet 51 and inner face leakproof Piece 54 is substituted.Also that is, the thickness direction of the region 33b without tergite, which at least overlaps with, is contained in rear side coupling member 40B's Leakage prevention sheet 51 is prevented from body fluid and is sewed from region 33b so even if being not provided with tergite 33.In the region without tergite In 33b, leakage prevention sheet 51 and inner face leakage prevention sheet 54 are preferably the not face skin face for being engaged in cover plate 34.In this way, by spy Meaning ground forms the region 33b without tergite, and the aeration and flexibility of 30 end of absorbability ontology can be improved.Moreover, by In the region 33b without tergite come leakage prevention sheet 51 and/or the inner face leakage prevention sheet 54 of overlapping, the work(of substitute tergite 33 can be played Can, thus prevent body fluid to be sewed from region 33b.

More than, in this case specification, in order to express present disclosure, carried out while with reference to attached drawing of the invention real Apply the explanation of mode.But the present invention is not limited to the above embodiments, and should can be according to this case specification comprising one's own profession dealer The item of record be readily contemplated by one that it is various it is self-evident sexually revise form or improvement form.

Utilization possibility in industry

It present invention can be suitably applied to the disposable diapers such as underwear type or band type.To which the present invention is suitable for application in deserted Diaper manufacturing industry.
