Rib collar (cuff) 20 is installed in absorber 12 dividually on horizontal X absorbing surface side is leaked in a pair of resistance.Resistanceleak rib collar 20 have the horizontal X outside that is inabsorber 12 and utilize not shown hot-melt adhesive etc. be engaged inleakage prevention sheet 13lateral border 21, and andabsorber 12 is overlapping and themedial border 22 that can leave from top flat 16.Medial border 22 is not engaged in absorber 12 etc., andrib collar elastomer 23 can be installed with elongation state along thismedial border 22 with shrinking.Rib collar elastomer 23 is installed in and crotch region 4 corresponding positions at least.Byrib collar elastomer 23 is installed as mentioned above like that,medial border 22 can leave with the mode self-priming acceptor 12 that erects, and near wearer's pars inguinalis, can prevent that Excretas such as urine from leaking from here bymedial border 22 driving fits.

Hindering the front andback fin 30,40 that is laminated with the horizontal X extension in edge on theleakage rib collar 20 and on vertical Y, separates.Front andback fin 30,40 for example can adopt the quality of per unit area to be about 10～20g/m², preferably be about 15g/m²Spunbonded type meltblown spunbonded type (SMS) fabric nonwoven cloth.Front andback fin 30,40 is installed in respectively in the precedingback waist region 2,3, and has such size, that is, the length dimension greater than the horizontal X of thetergite 11 ofback waist region 2,3 before the formation under unfolded situation with it, stretches out from the both side edges oftergite 11.

Beforefin 30 have theexternal end edge 30a that extends along horizontal X overlappingly with front-end edge 5, theinterior ora terminalis 30b that relatively extends withexternal end edge 30a, and the bothside edges 30c that extends of Y longitudinally along horizontal X.Theinterior ora terminalis 40b that backfin 40 has theexternal end edge 40a that extends along horizontal X overlappingly withend edge 6 similarly, relatively extend along horizontal X withexternal end edge 40a, and the bothside edges 40c that extends of Y longitudinally.Before and afterfin 30,40 also have can from tergite 11 stretch out and be positioned at bothside edges 30c, 40c side a pair of front and backalar part 31,41, and and tergite 11 overlapping and link the linkingpart 32,42 of a pair of front and backalar part 31,41.

Before and after be formed with the front and backwing folding line 33,43 that Y longitudinally extends behind fin 30,40pro-between alar part 31,41 and the linkingpart 32,42, front and backalar part 31,41 along front and backwing folding line 33,43 to horizontal X folded inside.Before and afterwing folding line 33,43 be formed on and bothside edges 7 position overlapped roughly.Front and backalar part 31,41 and linkingpart 32,42 after folding are overlapping, utilize temporary fixedparts 50 temporary fixed between itself and linkingpart 32,42.Temporary fixedparts 50 for example are provided with by a plurality of utilizations heating, the point that forms that pressurizes that separate on vertical Y and horizontal X.By temporary fixed like this, front and backalar part 31,41 and linkingpart 32,42 are temporary fixed mutually, but under the situation that desire is peeled off them, can easily peel off with hands.That is, can easily front and backalar part 31,41 be launched to the outside of horizontal X.

As temporary fixedparts 50, except point-like, also can be the member of the vertical Y or the wire of laterally extending continuously on the X longitudinally Y or laterally X be arranged with a plurality of.Forming under the situation of temporary fixedparts 50 by heating, pressurization, front andback fin 30,40 forms the fiber heat fusing of these sheets owing to contain thermoplasticity synthetic resin, can engage one another.In addition, also can utilize adhering parts such as hot-melt adhesive to engage, in this case, front andback fin 30,40 also can not contain thermoplasticity synthetic resin.

The temporary fixed bond strength of front and backalar part 31,41 and linkingpart 32,42 is about 0.03～1.0N, preferably is about 0.1～0.5N.Its reason is, at bond strength during less than 0.03N, front and backalar part 31,41 and linkingpart 32,42 be temporarily fixed at except it is peeled off the time can peel off without authorization, at bond strength during greater than 1.0N,alar part 31,41 before and after being difficult to peel off.In addition, temporary fixed bond strength also can be bigger near bothside edges 30c, 40c, and is less near the pro-rearwing folding line 33,43.By bigger near bothside edges 30c, 40c, can not increase whole bond strength and just be difficult to peel off front and backalar part 31,41.And, temporary fixed near bothside edges 30c, 40c by front and backalar part 31,41, can prevent that this front and backalar part 31,41 from curling, therefore, temporary fixedparts 50 are formed near bothside edges 30c, the 40c at least, in other zones are not to form temporaryfixed parts 50.

Opened about 5～20mm from bothside edges 30c, 40c minute by the point that heating, pressurization form.Its reason is, under the situation of this distance of separation less than 5mm, the amount of gripping before and after launching during alar part is less, is difficult to clamping, and during greater than 20mm, bothside edges 30c, 40c curl easily or be wrinkling easily at distance of separation.

In linkingpart 32,42, only be to utilize not shown adhering parts such as hot-melt adhesive to be engaged in resistance near the horizontal X inboard ofouter edge 30a, 40a and front and backwing folding line 33,43 to leakrib collar 20 andegative film 10,interior ora terminalis 30b, 40b do not engage, and form disengaged regional 34,44.Because being installed betweenfin 30,40 and the absorber 12 behind the pro-with erecting, the resistance that separatesleaks rib collar 20, therefore, when this resistanceleakage rib collar 20 separates, the mode that the linkingpart 32,42 of front andback fin 30,40 also separates with self-priming acceptor 12 moves, and can form bag between these absorbers 12 and linkingpart 32,42.Because bag can be accommodated Excretas such as defecation, therefore, can prevent of front and backora terminalis 5,6 leakages of these Excretas from dress article 1.

On thelateral margin 40c ofback fin 40, be separately installed with a pair of the 1st engaging part 60.As shown in Figure 2, the 1stengaging part 60 hassheet 61 that extends along horizontal X and thehook part 62 that is installed on sheet 61.Sheet 61 for example is about 50～80g/m by the quality of per unit area², preferably be about 70g/m²Polypropylene spun-bonded type (PPSB) fabric nonwoven cloth form, abuttingend 63 is installed onback alar part 41, and, on theexternal part 64 that faces one another on the horizontal X,hook part 62 is installed at abutting end 63.External part 64 mutual butt and being engaged under the folded state ofback alar part 41.

Under the situation that back alarpart 41 folds along rearwing folding line 43,hook part 62 is relative with the linkingpart 42 ofback fin 40, and, can be sticked in the fiber that forms linking part 42.Be sticked in linkingpart 42 like this byhook part 62, can prevent that the 1stengaging part 60 is curling without authorization.The engaging power ofhook part 62 and linkingpart 42 is about below the 2.4N, preferably is about 0.5～1.0N.Engaging power is to use the autoplotter of Tianjin, island シ ス テ system ソ リ ユ one シ ヨ Application ズ (System Solutions) company limited system to measure.Say that at length setting between the chuck is that 60mm, draw speed are 300mm/min, has measured engaging power (N).

Between theexternal part 64 of mutual the 1st engagingpart 60 of butt, vertically be formed with a plurality ofslits 65 discontinuously on the Y,external part 64 engages one another between slit 65.For theexternal part 64 that engages,, can make between theslit 65 and split, thereby can easily they be separated by they are stretched to the horizontal X outside.The length of vertical Y ofslit 65 is about 5mm, and the separately size between theslit 65 is about 0.3m m.Bysuch formation slit 65, can make the hot strength between theexternal part 64 be about 1～20N, preferably be about 6～16N.Hot strength is to use イ Application ス ト ロ Application ジ ヤ パ Application カ Application パ ニ イ リ ミ テ Star De, and (InstronJapan CO., LTD.) instron of corporate system is measured.Say that at length setting between the chuck is that 30mm, draw speed are 100mm/min, has measured maximum intensity (N).As the working sample of the 1stengaging part 60, adopt to comprise the sample that length dimension that mode that slit 65 forms part is cut to vertical Y is about 25mm.

The 2nd engagingpart 70 that can be sticked in above-mentioned the 1stengaging part 60 is formed on the garment-side of the dress of tergite 11.The 2ndengaging part 70 comprises ring component, extends along horizontal X between the bothside edges 7 ofback waist region 3.

As shown in Figure 1, in dress article 1, with folding after front andback alar part 31,41 position overlapped be formed withwaist folding line 80, precedingback waist region 2,3 alongwaist folding line 80 to horizontal X folded inside.In addition, in the present embodiment, under the state of Fig. 1, the bothside edges 7 of dress article 1 lodges to horizontal X inboard in crotch region 4 at least, but might not be defined in this, also can be that bothside edges 7 is launched to the horizontal X outside.Waist folding line 80 extends to bothside edges 7 from front andback ora terminalis 5,6, and vertical centrage P-P tilts with respect to imagination.Byback waist region 2,3 before folding alongwaist folding line 80, be formed withwaist fold domain 81, before back waistregion 2,3 horizontal X length dimension at least the state at each elastomeric contraction state, before being dress article 1 dress just do not make each elastomer overcome its contractility and under the state that extends, less than the length dimension of the horizontal X of crotch region 4.

Above-mentioned dress article 1 is fit to used as the absorbability pad under the state that is formed with waist fold domain 81.That is, under state shown in Figure 1, make dress article 1 touch wearer's thigh, the side for example fixes dress article 1 with cover of diaper from it.In that dress article 1 is used as under the situation of absorbability pad, when it is changed, only launch cover of diaper, with the side extraction from behind of the dress article 1 after using in the wearer's who lies on the back abdominal part side.New dress article 1 is inserted between cover of diaper and wearer's the behind and wears.When inserting like this because the length dimension of the horizontal X of the precedingback waist region 2,3 of dress article 1 less than the length dimension of the horizontal X of crotch region 4, therefore is easy to insert, preceding backwaist region 2,3, particularly before and afteralar part 31,41 can not be in the way.In addition, by being formed withwaist fold domain 81, can prevent that Excreta such as urine from flowing to the horizontal X outside.In addition, after inserting dress article 1,waist fold domain 81 can be opened and enlarged absorption area and use to the horizontal X outside.

The length dimension of vertical Y ofback fin 40 is length dimension about below 40% of vertical Y ofegative film 10, preferably is about 20～30%.Its reason is, at the length dimension of vertical Y ofback fin 40 greater than 40% o'clock, with dress article 1 as under the situation of absorbability pad, the bigger scope ofabsorber 12 is covered the area decreases that can absorb by the linkingpart 42 ofback fin 40 and back alar part 41.Its reason is that also defecation etc. are excreted on theback fin 40 that is overlapped inabsorber 12, and it is easy to leak fromend edge 6.

Before the length dimension of vertical Y offin 30 be length dimension about below 25% of vertical Y ofegative film 10, preferably be about 15～20%.Its reason is that the length dimension of vertical Y ofpro-fin 30 was greater than 25% o'clock, and particularly under the situation of male wearer, homaluria is to preceding fin 30, and it is easy to leak from front-end edge 5.

Above-mentioned dress article 1 not only is fit to use the situation of cover of diaper, for example also is fit to the so-called split pants that use in China mostly.Split pants particularly are used for the child mostly, and the part of the leg portion of trousers is not sewed up and opening, and wearer's leg portion is exposed when opening lower limb.Inserting dress article 1 from the opening portion of these trousers and as under the situation of absorbability pad, the precedingback waist region 2,3 of dress article does not bend or do not collude extension, just can easily wear.
