Summary of the invention
Invent the project to be solved
As previously mentioned, forming multiple tucks by the rear body in disposable diaper, it cooperate diaper can and comply with wearer's body The stretching, extension of body, and the fit sense or wearing feeling of diaper can be promoted.However, since the tuck is rolled over by constituting the sheet element of rear body It is folded to be formed, so the aeration of sheet element overlapping part can reduce, makes moisture entrapment between wearer's skin and diaper, have The anxiety of unplessantness displeasure is brought to wearer due to wet bored.In addition, more thering is aeration is significantly reduced to ask when tuck number is multiple Topic.
Thus, the purpose of the present invention is be separated into abandoning for predecessor's exterior body, rear body exterior body and absorbability ontology In formula diaper, the aeration of tuck forming part is improved.
Solve the technical solution of project
The present invention is about a kind of disposable diaper.Disposable diaper of the invention has:Before wearer's abdomen side Body exterior body 10, positioned at the rear body exterior body 20 of wearer back side and positioned at the absorbability ontology 30 of wearer's in-leg.This Invention is applicable to any of underwear type disposable diaper and band type disposable diaper.Underwear type disposable diaper, before being Body exterior body 10 is with rear body exterior body 20 by engaging in the side sealing portion being located at left and right sides of disposable diaper width direction And it is connected to substantially a ring-shaped, and it is formed with positioned at wearer around the loins opening portion of belly part and surrounds positioned at wearer The type of the leg opening part of bipod part.Band type disposable diaper is then in predecessor's exterior body 10 and rear body exterior body 20 The width direction both side ends of one side exterior body are equipped with the above fixing belt of pair of right and left, and another by the way that fixing belt to be fixed on Side exterior body and the type for being installed in wearer's in-leg.
Absorbability ontology 30 via have extend disposable diaper width direction to upper fold 41 and downwards folding part 42 Linking part 40 and be linked to the two or the exterior body of any one of predecessor's exterior body 10 Yu rear body exterior body 20.It is referred to herein " to upper fold " refers to that upward convex fold back part in wearing effect, alleged " downward folding part " then refer in wearing effect downwards Convex fold back part.In addition, the linking part 40 can be the other independent structure separated from predecessor's exterior body 10 and rear body exterior body 20 Part can also be the component with exterior body in one.In addition, when list claims " exterior body ", referring to predecessor's exterior body in this case specification 10 with the two of rear body exterior body 20 or any one.
According to above-mentioned composition, by the way that linking part 40 is arranged between absorbability ontology 30 and exterior body 10,20, and in the connection Portion 40 forms tuck, that is, the aeration of tuck forming part can be improved.
Furthermore in the present invention, absorbability ontology 30 has:Disengaged position 30a is not engaged in the end of length direction In linking part 40 towards skin face;And junction 30b, crotch side is more leaned in length direction compared with the disengaged position 30a Be engaged in linking part 40 towards skin face.If being more particularly described, entire width of the absorbability ontology 30 in length direction end Direction region is not engaged in linking part 40, but leave the linking part 40 towards skin face.The part is " disengaged position 30a".On the other hand, absorbability ontology 30 is at least leaning on the region of disposable diaper lower crotch side compared with the disengaged position 30a Locally be engaged in linking part towards skin face (in other words, comprehensive or locality).The absorbability ontology 30 and linking part The part of 40 engagements is " junction 30b ".In addition, absorbability ontology 30 and linking part 40 are to belong to distinctly in the present invention Part body.
As previously mentioned, in the present invention, since linking part 40 is formed with tuck, therefore compared to the general throwing of the not formed tuck Abandoning formula diaper, is formed with the part of the tuck, and aeration is poor.Therefore, according to above-mentioned composition, by the length for making absorbability ontology 30 Linking part 40 is left in degree direction end, can make to be easier to generate gap between the end of absorbability ontology 30 and linking part 40, therefore Aeration near tuck is promoted.If in this way, even if being formed with tuck using linking part 40 and it can be made according to need When the composition of expansion, being trapped in the moisture near tuck can be efficiently discharged, which, which occurs wet bored situation, can get Inhibit.
In disposable diaper of the invention, absorbability ontology 30, which preferably has, to be consolidated along its length with elongated condition Fixed elastic telescopic component.In this way, by being fixed on elastic telescopic component with elongated condition positioned at absorbability ontology 30 Length direction end disengaged position 30a, which can play a role, roll disengaged position 30a, The disengaged position 30a of absorbability ontology 30 is enabled to leave linking part 40.Therefore, the disengaged position 30a of absorbability ontology 30 with It is easier to generate gap between linking part 40, aeration is made to be maintained kilter.
In disposable diaper of the invention, elastic telescopic component preferably extends to junction from disengaged position 30a 30b.In this way, by formed along its length the elastic telescopic component of elongated condition be fixed on disengaged position 30a and Junction 30b can make the convergent force of elastic telescopic component play a role, so that disengaged position 30a is from the junction side 30b It rolls.Therefore, it is only secured to the situation of disengaged position 30a compared to elastic telescopic component, elastic telescopic component is fixed on The mode of disengaged position 30a and junction 30b can more effectively be such that the disengaged position 30a of absorbability ontology 30 leaves Linking part 40.
In disposable diaper of the invention, elastic telescopic component can also be more than disengaged position 30a and junction 30b and Extend absorbability ontology 30 covers whole length direction region.In this case, elastic telescopic component can also be at joint portion Position 30b at least partially makes it not show retractility.For example, the elastic telescopic component partial of junction 30b can will be located at Ground cutting, or elasticity can be made to stretch by by elastic telescopic component partial being fixed on junction 30b with non-elongated condition Contracting component does not show retractility.Herein, the elastic telescopic structure as the whole length direction region for extending absorbability ontology 30 Part is that three-dimensional corrugation telescoping member 36 or leg telescoping member 37 can be used in a manner of aftermentioned.But three-dimensional corrugation telescoping member 36 Or leg telescoping member 37, when the whole length direction region of absorbability ontology 30 has retractility, the meeting of absorbability ontology 30 exists Lower crotch is substantially bent and has the misgivings for undermining fit sense.Therefore, as previously mentioned, by the junction of absorbability ontology 30 30b makes the contractility of elastic telescopic component locally fail, and maintains the fitness of absorbability ontology 30, while can also maintain to inhale The disengaged position 30a's of the property received ontology 30 rolls effect.
In disposable diaper of the invention, linking part 40, which has, to be located between upper fold 41 and downward folding part 42 Between region 43.The intermediate region 43 has engaging zones 43a, and engaging zones 43a is in linking part 40 to upper fold 41 and downwards In the state that folding part 42 is in folding, it is peelable or be not bonded on strippingly the intermediate region 43 in face of towards skin surface side The two or the position of any one of position with the position in face of not face skin surface side.In addition, intermediate region 43 is in engaging zones It is not only engaged in 43a face-to-face to the position of skin surface side, it is also engageable in the position for facing not face skin surface side.And And engaging zones 43a can cover the whole region of intermediate region 43, but in this case, engaging zones 43a is by intermediate region 43 It is strippingly engaged in face of position (also that is, interim engagement).In addition, engaging zones 43a can also can not by intermediate region 43 It is engaged in removing in face of position, but in this case, engaging zones 43a is partially disposed at intermediate region 43.In addition, engagement When region 43a is set to a part of intermediate region 43, other regions are then known as non-set out region 43b.In addition, being abandoned in underwear type In formula diaper, function of the performance of so-called side sealing portion 4 as engaging zones 43a referred to herein also may be interpreted as.

As shown in figure 3, each coupling member 40A, 40B are folded into section substantially N font, in each coupling member 40A, 40B In upper end, the region towards skin surface side is engaged in each exterior body 10,20, and in the lower end of each coupling member 40A, 40B, face Absorbability ontology 30 is then engaged in the region of skin surface side.If illustrate, coupling member 40A, 40B have:Wear shape In upward convex to upper fold 41 in state;It and is in downwardly convex downward folding part 42 in wearing effect.In present embodiment, if will be to Upper fold 41 is compared with downward folding part 42, and relatively, to upper fold 41 in not face skin surface side, downward folding part 42 then exists position Towards skin surface side.These width directions to upper fold 41 with downward folding part 42 along each coupling member 40A, 40B are linearly prolonged It stretches.Therefore, by folding along these to upper fold 41 and downward folding part 42, each coupling member 40A, 40B are in section substantially N Font, and being formed includes the part for being laminated into 3 layers.In this case specification, it can be folded along to upper fold 41 and downward folding part 42 Each coupling member 40A, 40B construction be known as " tuck ".In present embodiment, though each coupling member 40A, 40B are made section Substantially N font, but not limited to this, can also be in the section substantially font of falling N or the construction with multiple tucks.
In addition, as shown in figure 3, each coupling member 40A, 40B using folding part 42 to upper fold 41 and downwards as boundary line and It is divided into intermediate region 43, inside region 44 and lateral area 45.Intermediate region 43 is located to upper fold 41 and downward folding part Region between 42.Furthermore inside region 44 is top to be extended to from downward folding part 42 to each exterior body 10,20 sides, and have It is engaged in the region of the junction 44a of the not face skin surface side of the exterior body.In addition, in the example of Fig. 3, inside region 44 Though whole region be formed as junction 44a, as long as at least part of inside region 44 is bonded on each exterior body 10,20 i.e. It can.Also, lateral area 45 is to extend to lower section to upper fold 41 to 30 side of absorbability ontology, and have and be engaged in the absorbability The region of the junction 45a of the not face skin surface side of ontology 30.In addition, lateral area 45 is in the example of Fig. 3 with lower end side A part of region of (lower crotch side) as junction 45a, but lateral area 45 can also whole region be bonded on absorbability sheet Body 30.Each junction 44a, 45a described herein as can be realized using the known bonding agent such as hot-melt adhesive.In addition, outside The junction 45a in region 45 is Chong Die with the junction 30b range of aftermentioned absorbability ontology 30.
In example shown in Fig. 3, the inside region 44 of each coupling member 40A, 40B are bonded on each exterior body 10,20 length The not face skin face of direction lower end.In addition, the lateral area 45 of each coupling member 40A, 40B are bonded on absorbability ontology 30 Length direction upper end not face skin face.In this way, each coupling member 40A, 40B can play each exterior body of connection 10,20 with the effect of absorbability ontology 30.In addition, the inside region 44 shown here as each coupling member 40A, 40B is bonded on respectively The example of the lower end side of exterior body 10,20.But the inside region 44 also engageable upper end side in each exterior body 10,20.Inside Region 44 will be bonded on which position in the not face skin face of each exterior body 10,20, be freely to design to a certain extent.
In addition, returning Fig. 2 to be illustrated, each coupling member 40A, 40B are being in upper fold 41 and downward folding part 42 Folded state.In this state, at least part of intermediate region 43 in entire width direction region has engaging zones 43a, be strippingly bonded on intermediate region 43 faces the position towards skin surface side.Furthermore in example shown in Fig. 2, Intermediate region 43 has been formed locally engaging zones 43a, and the part other than the part is then used as non-set out region 43b.For example, ginseng When illustrating according to the example of Fig. 3, inside region 44 be located at intermediate region 43 towards skin surface side, engaging zones 43a shown in Fig. 2 In, at least intermediate region 43 and inside region 44 are in engagement state.In addition, intermediate region 43 can substitute in engaging zones 43a Inside region 44 is engaged positioned at the lateral area 45 or absorbability ontology 30 of its not face skin surface side or intermediate region 43 It can also come together to engage the lateral area 45 or absorbability ontology 30 positioned at its not face skin surface side with inside region 44.According to This mode, in engaging zones 43a, each coupling member 40A, 40B are fixed into folded state, to limit its careless expansion.It is logical It crosses and removes engaging zones 43a, each coupling member 40A, 40B can be made to be unfolded.In addition, Fig. 3 is to show the non-set out region The profilograph of the part 43b.
In Fig. 2, conceptually apply shading in engaging zones 43a to show.In example shown here, engaging zones 43a is configured to:In each coupling member 40A, 40B and each exterior body 10,20 regions for being overlapped in thickness direction, engaging zones 43a is located at left and right sides of the width direction of 30 region of absorbability ontology, without Chong Die with absorbability ontology 30.That is, bowing Depending on, the length direction range of each exterior body 10,20, each coupling member 40A, 40B and 30 overlapping parts of absorbability ontology As non-set out region 43b.In this way, engaging zones 43a can also be defined as:In range not Chong Die with absorbability ontology 30 In, in the region in width direction with one fixed width.But in underpants-style diapers, former side face sealing portion 4 itself can be played The function of engaging zones 43a.Therefore, in underpants-style diapers, it can say and be not necessarily intended to recycle hot melt viscous except side sealing portion 4 It connects agent etc. and engages coupling member 40A, 40B with each exterior body 10,20.That is, the engaging zones 43a shown in Fig. 2 with shading Omission can be given.
If according to above-mentioned composition, by the way that company is arranged between absorbability ontology 30 and exterior body 10,20 with part body mode out of the ordinary Knot 40 makes the extensibility of tuck be improved to form tuck.That is, when by absorbability 30 pulling of ontology, linking part 40 can be with The movement and tuck is unfolded, therefore be to be easier to that tuck is unfolded.Then, if tuck is through being unfolded, tuck is by wearer When clothes worn etc. pushes, so that it may the function just like side Pu is played, it may also be desired that the moisture of diaper inside will be stranded in by playing The effect of discharge.In addition, each exterior body 10,20 is linked in advance with absorbability ontology 30 by each coupling member 40A, 40B, then In each coupling member 40A, 40B expansion for constituting tuck, each exterior body 10,20 and absorbability ontology 30 can be made towards length direction It leaves, and can be towards the elongated lengthwise of disposable diaper.Fig. 4 and Fig. 5 is conceptually to show by by engaging zones 43a Each coupling member 40A, 40B is unfolded in removing, the spatial spread for defining these coupling members, and makes each exterior body 10,20 The situation separated with absorbability ontology 30.In this way, it open up the tuck of each coupling member 40A, 40B can according to need through formation The structure opened, the movement displacement for making each exterior body 10,20 or absorbability ontology 30 that can follow wearer adjusts, therefore can effectively prevent The situation in gap is only generated between wearer's skin and diaper.Moreover, because fit performance of the diaper to wearer's skin improves, therefore Wearing feeling can be promoted.In the case where aforementioned engaging zones 43a can be removed towards length direction, by removing engaging zones 43a, Each coupling member 40A, 40B can be made to be unfolded as shown in Figures 4 and 5.
Furthermore it as shown in Fig. 2, is folded completely along folding part 42 to upper fold 41 and downwards in each coupling member 40A, 40B In state, each exterior body 10,20 is preferably covering 30 length direction end of absorbability ontology towards skin face.That is, passing through edge The engaging zones of each coupling member 40A, 40B that width direction extends extended to upper fold 41 (referring to Fig. 3), along its length Edge, intermediate region 43 and the lateral area 45 of 43a, can define the space with downwardly open portion.Moreover, can will inhale The length direction end of the property received ontology 30 accommodates should be in space.In addition, though illustration omitted, constitutes the suction of absorbability ontology 30 The length direction end of acceptor 31 also may be housed in the space defined herein in.It thereby constitutes, along the length of absorbability ontology 30 The body fluid or soft stool that direction stream comes may be housed in this space, and can prevent from leaking out toward external.
In addition, intermediate region 43 can not also strippingly be engaged in inside region 44 or lateral area in engaging zones 43a 45.In this case, due to intermediate region 43 on the 43b of non-set out region and be not engaged in be located at towards skin surface side and non-face To the position of skin surface side, so each coupling member 40A, 40B can freely be unfolded according to need.In this case, it such as wears When person's setting in motion, in non-set out region 43b, the tuck of each coupling member 40A, 40B are with regard to unfolded.Due to the movement of wearer When the non-deployed condition and unfolded state of each coupling member 40A, 40B being presented repeatedly, the space defined by each coupling member is just Can when and the when of expansion and reduce, make each coupling member tuck part generate just like side Pu function, make to be stranded in the space Air be persistently discharged.By the expansion for utilizing tuck in this way, it is easy to the sky of each coupling member 40A, 40B will be stranded in Interior moisture discharge, and the aeration of tuck forming part can be improved.In addition, the width direction of coupling member 40A, 40B are left In right both ends, in addition to exterior body 10,20 laps, though imposed side sealing, can also by the lap with Side is sealed at peelable or not peelable exterior body 10,20 together.The lap and exterior body 10,20 together side are sealed When conjunction, engaging zones 43a can be omitted.In addition, the length direction in the width direction left and right ends portion of coupling member 40A, 40B is whole In addition a region can also make not stripable board side with exterior body 10,20 and seal.
In this way, it intermediate region 43 and engages its engaging zones 43a in face of position and can temporarily engage for stripable board It is engaged with not stripable board any.The stripable board of engaging zones 43a described herein as temporarily engages and not stripable board Engagement can be realized using the known bonding agent such as hot-melt adhesive, as long as adjusting the coating weight of its bonding agent or adhesion strength can It is selected as stripable board or not stripable board.So-called stripable board engagement state, it is intended that when being for example susceptible to be removed in advance, The two can be removed, rhegma or damaged engagement occurs without making intermediate region 43 or constituting its sheet element in face of position State.Relatively, alleged not stripable board engagement state then means not to be susceptible to for example to remove in advance, if being then intended to implement When removing, in intermediate region 43 or it can be constituted in face of sheet element generation rhegma at position or the engagement state of breakage.In addition, connecing Though the entire width direction region of intermediate region 43 can be covered by closing region 43a, in this case, engaging zones 43a will be intermediate Region 43 strippingly engages (also that is, interim engagement) to it in face of position.Furthermore though engaging zones 43a can also be by middle area Domain 43 is not joined to its position faced strippingly, but in this situation, engaging zones 43a is locally provided at intermediate region 43 Width direction.
[the sheet material lit-par-lit structure of linking part]
Then, referring to Fig. 6, the construction for just constituting the sheet element of linking part 40 (coupling member 40A, 40B) etc. is illustrated. Fig. 6 is will to be amplified the situation shown around rear side coupling member 40B shown in Fig. 3.Though lifting rear side coupling member 40B below Construction for illustrate, but the construction of rear side coupling member 40B described herein as is also applicable in front side coupling member 40A.
As shown in fig. 6, rear side coupling member 40B, which has, is laminated the construction of at least 2 sheet elements in thickness direction.That is, Fig. 6 institute In the example shown, rear side coupling member 40B has leakage prevention sheet 51 and is fitted in the outer sheet 52 of its not face skin surface side.Leakproof Piece 51 is to be directly bonded to rear body exterior body 20 and absorbability ontology 30, and the not face skin face of the leakage prevention sheet 51 is then bonded to outer Dough sheet 52.
Leakage prevention sheet 51 be opaque liquid sheet element, by prevent body fluid from rear side coupling member 40B leakage for the purpose of and configure Person.Same as aforementioned tergite 33, leakage prevention sheet 51 is preferably using plastic films such as polyvinyl resins.In particular, in order to ensure rear The aeration of side coupling member 40B, it is preferable to use be formed with micro- porous polyethylene film of multiple 0.1 to 4 μm of micropore As leakage prevention sheet 51.By that can prevent from reaching rear side to form leakage prevention sheet 51 with the sheet element of aeration and opaque liquid The body fluid of coupling member 40B leaks out, and can inhibit the position and wet bored situation occurs.
Outer sheet 52 is the sheet element being mainly made of non-woven fabrics, to improve the feel in the not face skin face of leakage prevention sheet 51 For the purpose of and configure.Though non-woven fabrics used herein is not particularly limited, can only enumerate such as Breathable nonwoven, point bonding non-woven fabrics, The materials such as spun-bonded non-woven fabrics, air-laid nonwoven fabrics, melt spraying non-woven fabrics, SMS non-woven fabrics, SMMS non-woven fabrics.Substantially, have saturating Fluidity and aeration and the good sheet element of feel can be used and make outer sheet 52.
In addition, as shown in Figures 3 to 6, in present embodiment, the front side of disposable diaper and each coupling member of rear side 40A, 40B are preferably one or more linking part telescoping member 46 having along configuring to upper fold 41.Linking part telescoping member 46 be the elastic telescopics component such as silk thread shape elastic rubber, along the width direction of disposable diaper with elongation state configure to Upper fold 41.As previously mentioned, constituted because each coupling member 40A, 40B are laminated by leakage prevention sheet 51 and outer sheet 52, therefore linking part As long as telescoping member 46 is fixed between leakage prevention sheet 51 and outer sheet 52.By being pre-configured with connection to upper fold 41 along this Portion's telescoping member 46 then passes through the contraction of the linking part telescoping member 46, the intermediate region 43 of each coupling member 40A, 40B Gap is just not likely to produce between each exterior body 10,20.Therefore, the appearance of diaper is improved, and fitness can also be promoted.
Furthermore as shown in Figures 1 and 2, in each coupling member 40A, 40B, towards disposable diaper length direction separate it is pre- Fixed interval is configured with a plurality of lower abdomen telescoping member 47 extended in the width direction.Lower abdomen telescoping member 47 is along deserted urine The state of the width direction elongation of cloth is fixed on each coupling member 40A, 40B.But lower abdomen telescoping member 47 is simultaneously not configured each The center of coupling member 40A, 40B width direction, alternatively, imposing such as locality cutting in order not to make it show retractility. That is, lower abdomen telescoping member 47 is substantially positioned at the width direction two sides of absorbability ontology 30.In addition, lower abdomen telescoping member 47 can also locally overlap the width direction both ends of absorbability ontology 30.Each lower abdomen telescoping member 47 is stretched with linking part above-mentioned Contracting component 46 is same, as long as being fixed between leakage prevention sheet 51 and outer sheet 52.When lower abdomen telescoping member 47 is shunk, connection Component 40A, 40B will scratch contracting and form multiple thin gauffers (tummy gather, lower abdomen gauffer).
[joint construction of linking part and absorbability ontology]
Then, referring to Fig. 6 to Fig. 8, with regard to linking part 40 (front side coupling member 40A, rear side coupling member 40B) and absorbability The joint construction of ontology 30 is described in more detail.The sectional view of Fig. 6 shows rear side coupling member 40B and absorbability ontology 30 Joint construction.Furthermore Fig. 7 (a) is the top view of absorbability ontology 30, and Fig. 7 (b) is the absorbability sheet along VII-VII hatching The profilograph of body 30.In addition, Fig. 8 is the drawing in side sectional elevation of the absorbability ontology 30 along VIII-VIII hatching.
As shown in Fig. 6 and Fig. 7 (b), absorbability ontology 30 has in 5 side end of loins opening portion of length direction not to be engaged In the disengaged position 30a towards skin face of each coupling member 40A, 40B.Also that is, absorbability ontology 30 is being set to length side It is not engaged in each coupling member 40A, 40B to the disengaged position 30a of end, but is in leave state.The absorbability ontology Though 30 disengaged position 30a can be not formed in the entire width direction region of 30 end of absorbability ontology, and be made only in width The a part in direction is spent, but is preferably formed in the entire width direction region of 30 end of absorbability ontology.In this case, it inhales The length direction end of the property received ontology 30 is not engaged in each exterior body 40A, 40B without exception in entire width direction region.In addition, In Fig. 6, in the region of disengaged position 30a, outer sheet 52, anti-is created as from not face skin surface side to towards skin surface side Sequentially (front end of absorber 31 is to reach non-to existing composition for dropping fraction 51, cover plate 34, tergite 33, absorber 31 and top flat 32 The junction region 30a), but 31 front end of absorber from 3 side of lower crotch towards 40 side of linking part also can not reach it is disengaged The region of position 30a.Also that is, disengaged position 30a from not face skin surface side to the region towards skin surface side can also be outer Dough sheet 52, leakage prevention sheet 51, cover plate 34, tergite 33 and top flat 32 are sequentially existing to be constituted.
On the other hand, absorbability ontology 30 more leans on 3 side of lower crotch of length direction to have comprehensively in more disengaged position 30a Property or locality are engaged in the junction 30b towards skin face of each coupling member 40A, 40B.Though junction 30b can It is not formed in the entire width direction region of 30 end of absorbability sheet, and is made only in a part of width direction, but preferably It is formed in the entire width direction region of absorbability ontology 30.Furthermore as shown in fig. 6, in thickness direction absorbability ontology 30 with Among the region of each coupling member 40A, 40B overlapping, the region other than aforementioned disengaged position 30a is preferably comprehensively Property is engaged in each coupling member 40A, 40B.In this way, absorbability ontology 30 is in 5 side of loins opening portion of length direction Linking part 40 is locally left in end, and other parts are then engaged in linking part 40.The engagement of absorbability ontology 30 described herein as Position 30b can be realized using the known bonding agent such as hot-melt adhesive.In addition, the junction 30b of absorbability ontology 30 Range be Chong Die with the range of junction 45a of lateral area 45 of aforementioned each coupling member 40A, 40B.Moreover, Fig. 6 In, the region of 30b in junction, from not face skin surface side to towards skin surface side, be in outer sheet 52, leakage prevention sheet 51, Sequentially there is the composition (front end of absorber 31 of (stacking) in junction 30b, cover plate 34, tergite 33, absorber 31 and top flat 32 Portion reaches the region of junction 30b), but 31 front end of absorber from 3 side of lower crotch towards 40 side of linking part can not also reach To the region of junction 30b.Also that is, the region of junction 30b is from not face skin surface side to can also towards skin surface side It is constituted for outer sheet 52, leakage prevention sheet 51, junction 30b, cover plate 34, tergite 33 and top flat 32 are sequentially existing.In addition, aforementioned The front end of absorber 31 also reaches the region of junction 30b, so that from 3 side of in-leg towards the absorber of 40 side of linking part 31 front ends are positions in the region 30b of junction.
In Fig. 7 (b), the length for the range that absorbability ontology 30 and rear side coupling member 40B are overlapped in thickness direction be with Symbol L1It indicates.In addition, absorbability ontology 30 be not bonded on the disengaged position 30a of rear side coupling member 40B length be with Symbol L2It indicates, absorbability ontology 30 is bonded on the length of the junction 30b of rear side coupling member 40B then with symbol L3It indicates. For example, the length L of disengaged position 30a2Length L relative to overlapping range1Ratio (L2/L1) it is preferably 1% or more, such as More excellent is 1 to 50%, and more excellent is 5 to 45%, and is special excellent with 10 to 40%.If indicated with specific value, disengaged position The length L of 30a2Preferably 1mm or more, such as more excellent is 3 to 100mm, more excellent is 5 to 30mm, then more excellent is 10 to 25mm, and It is special excellent with 10 to 20mm.In addition, the length L of junction 30b3As long as from overlapping range length L1Subtract disengaged position 30a Length L2?.Furthermore though being with regard to the disengaged position 30a of absorbability ontology 30 and the length phase of junction 30b herein Rear side coupling member 40B is illustrated, but explanation herein be equally applicable to absorbability ontology 30 disengaged position 30a and Length of the junction 30b relative to front side coupling member 40A.But absorbability ontology 30 is at disengaged position 30a and joint portion Position 30b links structure relative to front side relative to the length and disengaged position 30a and junction 30b of rear side coupling member 40B The length of part 40A may be the same or different.
As previously mentioned, the disposable diaper 100 of present embodiment is since each coupling member 40A, 40B are formed with tuck, therefore Compared to the general disposable diaper of not formed this tuck, the aeration that tuck forms part then can be slightly worse.Therefore, according to above-mentioned Each coupling member 40A, 40B, absorbability sheet are left in the mode of composition, the end on length direction by making absorbability ontology 30 It is easier to generate gap between the end and linking part 40 of body 30, so the aeration near tuck is promoted.If side according to this Formula, even if using the moisture being stranded near tuck in the composition that linking part 40 is formed with tuck that can be unfolded according to need It can efficiently be discharged, so that the position is generated wet bored situation and is can get and inhibit.Also that is, the disengaged position of absorbability ontology 30 30a has the effect for promoting aeration.
Furthermore as shown in Fig. 7 (a) and Fig. 8, absorbability ontology 30 has:The left side formed by three-dimensional corrugation telescoping member 36 Right a pair of three-dimensional corrugation;And the pair of right and left leg creases formed by leg telescoping member 37.As shown in figure 8, present embodiment In, three-dimensional corrugation and leg creases are to make a block piece component by three-dimensional corrugation telescoping member 36 and leg telescoping member 37 respectively (lateral plate 35) is shunk and former.If illustrating, as shown in figure 8, a part of lateral plate 35 is the back for being fixed on tergite 33 Face (not face skin face).Moreover, a part is fixed on the lateral plate 35 at the back side of tergite 33 along the length side of absorber 31 To, and returned more leaning on the inside of lateral absorbability ontology 3 outside width direction compared with the bonding station of top flat 32 and tergite 33 It rolls over and forms outside fold back portion 35a.In addition, by a part of lateral plate 35 of fold back portion 35a fold back on the outside with sandwich top flat 32 with The mode of tergite 33 and be fixed on the surface (towards skin face) of top flat 32.Moreover, lateral plate 35 is also from fixed with top flat 32 Fixed part 35b comes on the inside of width direction to extend." fixed part " referred to herein refers to that lateral plate 35 is fixed on the position of top flat 32 The boundary line at top flat 32 and the position in free state is not secured to lateral plate 35.Furthermore lateral plate 35 is towards more compared with fixed part 35b The part extended on the inside of width direction is in being formed to fold back on the outside of the width direction inside of absorber 31 or width direction Side fold back portion 35c.Then, three-dimensional corrugation is fixed with along the length direction of disposable diaper in the inside fold back portion 35c of lateral plate 35 Telescoping member 36.It stretches likewise, being fixed with leg along the length direction of disposable diaper in the outside fold back portion 35a of lateral plate 35 Component 37.In addition, leg telescoping member 37 could be secured between lateral plate 35 and tergite 33.Thereby structure, three-dimensional corrugation are flexible Component 36 just will form three-dimensional corrugation when shrinking, and then form leg creases when the contraction of leg telescoping member 37.
As shown in Fig. 7 (a), three-dimensional corrugation telescoping member 36 and leg telescoping member 37 not only extend absorbability ontology 30 Lower crotch 3, also extend into predecessor side and rear body side, and reach the length direction ora terminalis of absorbability ontology 30.Also that is, three-dimensional wrinkle Pleat telescoping member 36 and leg telescoping member 37 are to be fixed on side in the substantially the entire area of 30 length direction of absorbability ontology Piece 35.
As shown in Fig. 7 (a), three-dimensional corrugation telescoping member 36 and leg telescoping member 37 have under absorbability ontology 30 Crotch 3 is more than the length that junction 30b reaches disengaged position 30a again.In this way, by making three-dimensional corrugation telescoping member 36 and leg telescoping member 37 the two or any one also position is in disengaged position 30a, when these telescoping members 36,37 are shunk, The disengaged position 30a is pulled by each coupling member 36,37 and is erected.The disengaged position 30a of absorbability ontology 30 is erected Situation be to be illustrated in Fig. 7 (b).In this way, through utilizing three-dimensional corrugation telescoping member 36 or leg telescoping member 37 Convergent force erects the disengaged position 30a of absorbability ontology 30, the end of the absorbability ontology 30 and each coupling member 40A, Gap between 40B can be obtained maintenance.Thereby, the aeration near 30 end of absorbability ontology can be made to be promoted.
Furthermore as shown in Fig. 7 (a), three-dimensional corrugation telescoping member 36 is fixed on the whole of absorbability ontology 30 with elongated condition In the case where a length direction region, junction 30b, which also may be present, loses the contractility of the three-dimensional corrugation telescoping member 36 The failure portion 36a of effect.Likewise, junction 30b, which also may be present, makes the failure of its contractility for leg telescoping member 37 Failure portion 37a.Also that is, each telescoping member 36,37 is that failure portion 36a, 37a shown in Fig. 7 (a) are imposed and stretched it from showing The processing of contracting.For example, by that, by each telescoping member 36,37 fine cuttings, contractility can be made to lose in failure portion 36a, 37a Effect.In addition, can also make for example, each telescoping member 36,37 is fixed on lateral plate 35 with non-elongated condition in failure portion 36a, 37a Contractility failure.Although as long as failure portion 36a, 37a of each telescoping member 36,37 are located at the junction of absorbability ontology 30 30b, but be particularly preferably located near the boundary of junction 30b and disengaged position 30a.Specifically, respectively stretching At least part of failure portion 36a, 37a of contracting component 36,37 are preferably present in from junction 30b and disengaged position It rises in the range of 10mm the boundary of 30a.In this way, locally make respectively to stretch by the junction 30b in absorbability ontology 30 The contractility of contracting component 36,37 fails, so that it may avoid absorbability ontology 30 by each telescoping member 36,37 convergent force and substantially The phenomenon that scratching contracting or shrinkage.It thereby designs, the fitness of absorbability ontology 30 and wearer's skin can be obtained maintenance.
In addition, being to disclose both three-dimensional corrugation telescoping member 36 and leg telescoping member 37 to be present in absorbability ontology herein The example of 30 disengaged position 30a.But as long as any one of three-dimensional corrugation telescoping member 36 and leg telescoping member 37 are located at The disengaged position 30a of absorbability ontology 30.
More than, in this case specification, in order to express the contents of the present invention, carried out while referring to attached drawing of the invention real Apply the explanation of mode.But the present invention is not limited to above embodiment, and should be said comprising those skilled in the art according to this case The change mode or mode of ameliorating that item described in bright book can be readily contemplated by one that.
