ったものがある。2. Description of the Related Art There has been a remarkable improvement in disposable diapers in recent years, and a typical example of the improvement is to form barrier cuffs on both sides of the disposable diaper so as to particularly prevent lateral leakage of loose stool.

トカフスにより阻止しようとするものである。A typical example is disclosed in Japanese Patent Publication No. Hei 6-93901. This patent invention intends to prevent side leakage in a double manner with a barrier cuff and a gasket cuff. In particular, with regard to loose stools, the liquid portion of loose stool beyond the distal end of the barrier cuff is sought to be blocked by the gasket cuff.

ものとなることが知見された。However, according to subsequent studies by the present inventors, this type of double cuff has a limited effect, and surprisingly, by devising the form of the standing cuff, It has been found that stand-up cuffs alone (without gasket cuffs) provide benefits that far exceed double cuffs.

根本的な問題点を指摘すれば、この種の紙おむつでは、
ガスケットカフスが脚周りに当るとき、バリヤーカフス
の遠位端（遠位縁）が股の付け根に線接触するものであ
る。[0005] That is, to point out the fundamental problem of a disposable diaper having a double cuff, this type of disposable diaper has the following problems.
When the gasket cuff hits around the leg, the distal end (distal edge) of the barrier cuff is in line contact with the base of the crotch.

フスの脚周りへの当り部位に応じて、バリヤーカフスの
遠位端（遠位縁）の位置が定まり、目的の股の付け根に
線接触する位置が装着の都度変り、横漏れ防止効果が完
全でない場合が多くある。Therefore, in the mounted state, the position of the distal end (distal edge) of the barrier cuff is determined according to the contact area of the gasket cuff around the leg, and the position where the barrier cuff is in line contact with the desired crotch base is determined. In many cases, the side leakage prevention effect is not perfect.

後漏れを生じる可能性がある。[0007] Even though loose feces over the distal end of the barrier cuff can be blocked by the barrier cuff, there is a possibility of leaking back and forth.
【０００８】しかも、装着が適切でないと、内向き方向

液分を阻止できないことがある。[0008] In addition, if the mounting is not proper, the barrier cuff set in the inward direction may be warped outward, and it may not be possible to prevent loose stool liquid.

Naturally, the position of the barrier cuff must be shifted to the center side of the disposable diaper, the widthwise gap between the barrier cuffs on both sides is small, and the pocket space is wide. Or needed to catch loose stool).
【００１０】いずれにしても、母親は、横漏れを何度か

Both follow, and the upright distal end of the upright portion surely makes line contact with the base of the crotch, and at the same time, the flat contact portion comes in flat contact from there to around the leg, so that the paper diaper has a remarkably high side leakage prevention effect.

Acts on the standing cuff B itself, so that the standing portion 10 stands almost vertically. Although the flat contact portion 20 also stands vertically, the flat contact portion (extended portion of the flat contact portion 20) is fixed on the standing portion corresponding portion 20A in a state where the flat contact portion (extended portion of the flat contact portion 20) is turned over.
There is also a limit to the vertical standing, and the plane contact portion 20 stands while maintaining the vertical state while maintaining the vertical standing force (the force indicated by the arrow in FIG. 3).
【００４８】その結果、平面当り部２０は、常に、着用
者の脚周りに平面的にフィットする。As a result, the flat contact portion 20 always fits flatly around the wearer's leg.

トップ機能により横漏れが防止される。The space surrounded by the upright portions 10 and 10 forms a space for confining urine or loose stool. When urine is discharged into this space, the urine is absorbed into the absorber 3 through the liquid-permeable sheet 1, and the rising portions 10, 10 of the rising cuffs B serve as barriers for loose stool solids, Overcoming is prevented. In the unlikely event that urine leaks laterally over the standing distal side edge of the standing portion 10, lateral leakage is prevented by the stop function of the flat contact portion 10.

Further, the liquid-permeable sheet may be made to have a property of repelling liquid by silicon treatment or the like. Further, in the above-described embodiment, the upright end of the leg-surrounding erecting sheet 4 is the liquid-impermeable sheet 2 and the outside thereof is fixed to the backsheet 30, but the backsheet 30 is omitted and the liquid-impermeable sheet 2 is omitted. The sheet 2 may extend to the lateral edge of the product, and the erecting sheet 4 may be fixed to the liquid-impermeable sheet 2.

Those having a small shrinkage ratio are preferred. Specifically, when the elastic elastic member is made of thread rubber, the elastic elastic member 5 of the flat contact portion 20 has a shrinkage of 400 to 640d, a shrinkage of 160 to 300%, and the elastic elastic member 5 of the upright portion 10.

The difference from the above-described embodiment is that a gather having a flat gather cuff G, which gathers the skin by the contraction force of the elastic elastic member 5 and hits the skin two-dimensionally, and a modified example of the standing cuff B itself, The point is that the elastic stretching member 5 is provided near the folded edge of the portion 20. The elastic elastic member 5 arranged in the vicinity of the folded edge of the flat contact portion 20 has an advantage that the flat contact is ensured.

Urine and loose stool can be reliably captured, and both the upright portion and the flat contact portion follow the wearer's movement, ensuring that the upright distal end of the upright portion comes into line contact with the base of the crotch, and By contacting the plane contact part in a plane from to the leg circumference,
Advantages such as a remarkably high lateral leakage prevention effect are provided.
