Comprise multiple waistline elasticity structures of waistline opening elastic component 54a and secondary resilient members 54bPart 54 is to be folded between inner surface sheet 51 and appearance dough sheet 52 along the state that laterally B extends. Waistline elastic component 54 extends toEdge, both sides 26, more preferably extends to cutting ora terminalis 53, joins two sheets 51,52 to via hot-melt adhesive (not shown)At least one party. In each edge, both sides 26, show the row 40 at abutment 30 and abutment. The joint of each edge, both sides 26The row 40 of point are superimposed on diaper 10 with the row 40 at the abutment of each edge, both sides 24, formed the side seam district of diaper 10Territory 25. Inner surface sheet 51 engages via hot-melt adhesive 82 (with reference to Fig. 7) with appearance dough sheet 52.
The inner surface sheet 51 of the inner surface sheet 41 of Attacking Midfielder's region 21 and appearance dough sheet 42 and low back region 22 and outerSurface patch 52 is by thermoplastic synthetic fiber's nonwoven, for example spun-bonded non-woven fabrics or spin SMS-spun-bonded non-woven fabrics and form.As thermoplastic synthetic fiber, use the thermoplastic synthetic fiber of the fiber number with 0.1～4dtex to reach at per unit area7－25g/m2, 9～15g/m more preferably2The thermoplastic synthetic fiber of quality of scope. Use as nonwoven to have 7～25g/m2The material this point of quality, make the good or gas permeability of Attacking Midfielder's region 21 and low back region 22 softnesses and sense of touchPreferred in good aspect. Inner surface sheet 41 and appearance dough sheet 42 and/or inner surface sheet 51 and appearance dough sheet 52 have following feelingsCondition: by making the superimposed situation about forming of separated 2 nonwoven; And pass through 1 nonwoven at Attacking Midfielder's region21 apical margin 21a and/or the apical margin 22a of low back region 22 fold and the situation of formation. No matter that is to say in the present inventionIn which kind of situation, the side edge part 24 of front dummy slider 11 and the side edge part 26 of rear dummy slider 12 are all formed by 2 nonwoven. ThisOutward, although do not illustrate, at front dummy slider 11 and/or rear dummy slider 12, in other words, in Attacking Midfielder's region 21 and/or rear waistline districtTerritory 22, can append as required and use in edge, both sides 24 each other and/or extend each other edge, both sides 26Thermoplastic synthetic fiber's nonwoven. Append that the size of longitudinal A of the nonwoven of use can be than front dummy slider 11, rear dummy slider 12Longitudinally the size of A is little. The edge, both sides 24 and the edge, both sides 26 that form are like this at least 2 positions that nonwoven is superimposed.
In the situation that producing continuously diaper 10, each members such as the nonwoven that diaper uses are towards the horizontal stroke that becomes diaper 10Direction to B is supplied with. When such while supplying with nonwoven, the strength ratio of the nonwoven in diaper 10 on tending to longitudinally transverselyIntensity is low. Therefore,, forming the nonwoven of Attacking Midfielder's region 21 and forming in the nonwoven of low back region 22, respectively contain at leastThe tensile strength nonwoven lower than the tensile strength on horizontal B on 1 longitudinal A. In the present invention, in the intensity of nonwovenExist such difference just to mean, the thermoplastic synthetic fiber who forms nonwoven tends to extend towards horizontal B, instead of courtExtend to longitudinal A. If nonwoven is in such state, when controlling respectively Attacking Midfielder at the position in abutting connection with sidepiece seam region 25Region 21 is with low back region 22 and while wanting to make Attacking Midfielder's region 21 to separate on fore-and-aft direction C with low back region 22,Power performance is now pulled open the thermoplastic synthetic fiber who extends along horizontal B or it is ruptured at periphery from the periphery at abutment 30Effect, can easily tear the side in Attacking Midfielder's region 21 and low back region 22 at the periphery at abutment 30. EngagingPoint 30 is such action repeatedly one by one, thus can whole side seam region 25 easily separate Attacking Midfielder's region 21 and afterWaistline region 22. Tend to the nonwoven that extends instead of extend towards longitudinal A towards horizontal B as thermoplastic synthetic fiber,For example use spun-bonded non-woven fabrics, the operating direction while making to manufacture this nonwoven is with laterally B is consistent. But, such nonwovenCloth and the Attacking Midfielder's region 21, low back region 22 that use it easily split along horizontal B sometimes.
In diaper 10, in order to compare the tensile strength of nonwoven, compare as follows. Cut from diaper 10Lower Attacking Midfielder's region 21 and low back region 22 also impregnated in toluene solution, the hot-melt adhesive of its use are dissolved, by nonwovenThe a sheet by a sheet separation of cloth is also dry. From each nonwoven, make that longitudinal A is of a size of about 70mm, laterally B is of a size of about 25mmLengthwise test piece and longitudinally A is of a size of about 25mm, laterally B is of a size of the test piece of growing crosswise of about 70mm. By tension testThe chuck spacing of machine (for example, Shimadzu Seisakusho Ltd.'s universal testing machine AutographAG-Xplus or its equivalents)Be set as 50mm, for each test piece, respectively control long side direction both ends 10mm and stretch with the speed of 100mm/min, askGo out breaking load (N). For each test piece, obtain breaking load with respect to tension test before the width of Accurate Determining (WD) in advanceRatio (N/WD) is made as tensile strength, compares its tensile strength between each test piece.
In Fig. 2, form the crotch dummy slider 13 of crotch region 23 and have: with the skin of diaper wearer liquid permeability in opposite directionsInner surface sheet 61; With clothing appearance dough sheet 62 in opposite directions; Be positioned at inner surface sheet 61 under the core 63 of body liquid absorptive; WithAnd the leakage prevention sheet 64 of opaque liquid between appearance dough sheet 62 and core 63. Inner surface sheet 61 and the coated core 63 of appearance dough sheet 62Surfaces externally and internally, superimposed in the part of stretching out from the periphery of core 63, be bonded with each other via hot-melt adhesive (not shown), therebyForm front-end edge 65, end edge 66 and the both side edges 67 of crotch dummy slider 13. In the inner side of both side edges 67, be formed with disposable diaperIn usual leakproof dike 69. Leakproof dike 69 is called as three-dimensional fold sometimes, is also sometimes referred to as and erects fold. Elastic component 69bBe arranged on the inner edge portion 69a of leakproof dike 69 with elongation state. In addition, in the inner side of both side edges 67, along each both side edges 67 toThe leg that fore-and-aft direction C (with reference to Fig. 1) extends with the state extending encloses elastic component 68 and engages via hot-melt adhesive (not shown)To at least one party in inner surface sheet 61 and appearance dough sheet 62. The leading section 14 of crotch dummy slider 13 and the interior table of Attacking Midfielder's region 21Dough sheet 41 engages via hot-melt adhesive (not shown), and rearward end 16 is sticky via hot melt with the inner surface sheet 51 of low back region 22Connecing agent (not shown) engages.
Fig. 3 is the enlarged drawing of III in Fig. 2 part, in the four-headed arrow A presentation graphs 1 in Fig. 3 longitudinally. After formationThe side edge part 26 of the rear dummy slider 12 in waistline region 22, shows the abutment 30 and the abutment that are used to form side seam region 25Row 40, the side edge part 24 of these 25 engage side edges 26, side seam region and front dummy slider 11. The shape at each abutment 30 isParallelogram, has inner end 33 and outer end 34, and this inner end 33 is and will stretches the size two of horizontal B of diaper 10aThe relative inside line of center line P (with reference to Fig. 2) of decile, this outer end 34 is outside lefts relative with cutting ora terminalis 53,Inner end 33 is parallel to each other with outer end 34, as the top margin 38 at position, top and as the base 39 of lower portion at inner end33 and outer end 34 between extend. Prolong in the mode being parallel to each other and form descending towards cutting ora terminalis 53 on top margin 38 and base 39Stretch. Inner end 33 is with mode parallel with center line P or that intersect with center line P and imaginary straight line 35 phases that longitudinally A extendsConnect. Imaginary straight line 35 and the scope of the distance of separation L of cutting ora terminalis 53 on horizontal B at 4～13mm. Abutment 30 with inThe size M of the parallel longitudinal A of heart line P is no more than 1.5mm, and the size W of the horizontal B orthogonal with center line P is identical or ratio with size MSize M is large but be no more than 3mm, is more preferably no more than 2.5mm, longitudinally A the and laterally size of B is little, the particularly longitudinal size of ALittle, all length, area is also little. The side seam region 25 that comprises such abutment 30, laterally the size Q of B is for being no more than3mm, is more preferably no more than 2.5mm. In addition, the size Q in illustrated example is identical with size W. In addition, adjacent on longitudinal AAbutment 30 minimum is each other separated the scope of size N at 0.4～5mm, preferably large than the width of waistline elastic component 54,Be adjusted to and can make waistline elastic component 54 between abutment 30 size each other. In Fig. 3, the width of elastic component 54Refer to the size of longitudinal A.
There is no particular limitation for the shape at abutment 30, except comprising rectangle, foursquare parallelogram, alsoCan adopt the shape such as circle, ellipse, but example like this, is formed as from imaginary straight line 35 towards cutting ora terminalis 53 shapes as shownBecome the top 33a of descending and inner end 33 to be formed as the abutment 30 of acute angle, can make Attacking Midfielder's region 21 and low backPower when region 22 separates concentrates on narrow and small scope, can separate rapidly in this point is excellent.

Be positioned at the waistline elastic component 54 of side edge part 26, via being coated in inner surface sheet 51, outerHot-melt adhesive (not shown) on any member in surface patch 52, waistline elastic component 54 join to inner surface sheet 51 and/Or appearance dough sheet 52 and state in shrinking. Therefore, at the side edge part 26 of the diaper 10 obtaining from stretching, extension diaper 10a,Shrink by waistline elastic component 54, between cutting ora terminalis 53 and the outer end 34 at abutment 30, in other words, at cutting ora terminalis53 and side seam region 25 between, on inner surface sheet 51 and appearance dough sheet 52, produce fold and bending. This fold and bendingDuring in wearing effect, can hide abutment 30 at diaper 10, in addition, also can prevent that wearer's skin contact is to hardAbutment 30.
The row 40 at the abutment 30 shown in the side edge part 24 of the front dummy slider 11 in Fig. 2 and abutment, are stretching diaper 10a one-tenthDuring for diaper 10, become one and form sidepiece with the abutment 30 shown in the side edge part 26 of rear dummy slider 12 and the row 40 at abutmentSeam region 25. Therefore,, although do not illustrate, the abutment 30 of front dummy slider 11 has and inner end 33 and outer end too34 consistent inner end and outer ends, this inner end and imaginary straight line 35 join, and have with size L, the W of rear dummy slider 12,The size that M, N are identical. Incidentally, straight line 35 is the vacations that no matter can both expect in side edge part 24 or in side edge part 26Think line. And side edge part 24 also comprises the waistline elastic component 44 in elongation state, in an example of preferred side edge part 24In son, this waistline elastic component 44 extends to cutting ora terminalis 43.
In addition,, in diaper 10, stretch the cutting ora terminalis 43 shown in diaper 10a and cutting ora terminalis 53 sometimes as described laterDeposited. In such diaper 10, the non-seam between deposited all-in-one-piece cutting ora terminalis 43,53 and side seam region 25In region 29, the inner surface sheet 41 of front dummy slider 11 and appearance dough sheet 42 become one and shrink along horizontal B, meanwhile, and at rear dummy sliderIn 12 non-seam area 29, inner surface sheet 51 and appearance dough sheet 52 also become one and shrink along horizontal B, thereby connect at sidepieceThe outside in seam region 25, the portion of heaving 45 that forms the sleeve-like that longitudinally A extends by side edge part 24 and side edge part 26 is (with reference to figure4). This heaves portion 45 and can make the soft-touch of the side edge part 24,26 in diaper 10, or hiding abutment 30 makes diaper 10Outward appearance be rich in feeling of high class. In order to make non-seam area 29 form the portion of heaving 45 of sleeve-like, preferably make side seam region 25With cutting ora terminalis 43,53 4～10mm apart.
Fig. 4 is the IV-IV alignment view in Fig. 1, shows for example by side edge part 24 and side edge part 26 and has formed sleeve-likeThe situation of the portion of heaving 45 under diaper 10. Side edge part 24 and side edge part 26 are deposited integral at 30 places, abutment, have jointRow 40 and the side seam region 25 of point. Outside on the horizontal B in side seam region 25, cutting ora terminalis 43 and cut endEdge 53 is deposited, has formed and side seam region 25 closing line 46 that longitudinally A extends side by side. Side seam region 25 withBetween closing line 46, waistline elastic component 44 and 54 shrinks, thereby side edge part 24 and 26 bends to mutually projection round about,Formed the portion of heaving 45 of sleeve-like at the sidepiece of diaper 10. Diaper 10 in wearing effect, from horizontal or oblique observationWhen this diaper 10, side seam region 25 is hidden by the portion of heaving 45 of sleeve-like. Even from front or rear observe this diaper 10Time, side seam region 25 also can be hidden by the portion of heaving of sleeve-like 45 sometimes. In the time that the portion of heaving 45 is applied to pressing force, heavePortion 45 is flexibly out of shape, and in the time discharging from pressing force, heaves the shape in the 45 recovery figure of portion. The portion of heaving 45 like this can makeThe soft-touch in side seam region 25. In addition, as shown example like this by cutting ora terminalis 43 and 53 deposited absencesSide edge part 24 and side edge part 26 bending or generation fold separately, therefore, shape does not easily line up, and becomes sometimes infringement diaperA reason of 10 outward appearance.
In order to form the abutment 30 in diaper 10, can use usual in the art means. For example, make compoundWeb (ウ エ Block) moves and passes through usual ultrasonic welding machine along operating direction, and this composite web is not by also forming and connectThe front dummy slider 11 of chalaza 30 on horizontal B continuous web with the same rear dummy slider 12 that does not also form abutment 30 on horizontal BContinuous web is formed by stacking. In such composite web, the operating direction while making to manufacture the nonwoven of its use and compoundThe operating direction of web is consistent. Therefore, form in the nonwoven of composite web the differently-oriented directivity of the fiber of this nonwoven and compoundThe operating direction of web is consistent.
As ultrasonic welding machine, use the supersonic welding having along soldering tip roller and the anvil block roller of operating direction rotationPick. On side face at soldering tip with roller, set in advance the projection of the effect of performance soldering tip, to can form on composite webThe abutment of required form. Be formed with the composite web at abutment, the size on operating direction becomes the horizontal B of diaper 10The position of size cuts off. The cutter using when cut-out is heated to suitable temperature if necessary in advance, thereby can cut offWhen composite web, by deposited the cutting ora terminalis 53 of the cutting ora terminalis 43 of Attacking Midfielder's region 21 and low back region 22, can form sleeveThe portion of heaving 45 of mouth shape. But, the present invention can be not yet by cutting ora terminalis 43 and 53 deposited enforcements.
The diaper 10 that Fig. 1 illustrates for example, in the time being taken off, can be in the upper end of side edge part 24,26, before controlling on the other handWaistline region 21, controls on the other hand low back region 22, forwards to pull Attacking Midfielder's region 21, rearward to pull low back region22 the mode application of force, separates front and back waist region 21,22. In addition, also can be in the bottom of side edge part 24,26, on the other handControl Attacking Midfielder's region 21, control on the other hand low back region 22, forwards to pull Attacking Midfielder's region 21, rearward to pull low backThe mode application of force of region 22. If Attacking Midfielder's region 21 is separated at 30 places, abutment with low back region 22 like this, de-When lower diaper 10, need to be along the two legs diaper 10 of leaving behind. In the time pulling Attacking Midfielder's region 21 and low back region 22, pulling force is doneConcentrate on for the upper end of the row 40 at abutment or bottom the periphery having compared with the abutment of small size 30.
Therefore, at Attacking Midfielder's region 21 and low back region 22 at abutment 30 when the state in peeling off, canPeel off to make it to separate along fore-and-aft direction C Attacking Midfielder's region 21 and low back region 22 at this. In side seam region 25, connectThe area of chalaza 30 is little, and the inner end 33 at abutment 30 arranges along the imaginary straight line 35 in Fig. 2, therefore, and front waistline districtTerritory 21 is enclosed opening 28 or is enclosed opening 28 towards waistline from leg towards leg from waistline opening 27 with separating also of low back region 22Opening 27 roughly successfully carries out linearly. As illustrated for example in Fig. 3, have the top 33a's of acute angle at abutment 30In situation, the power of the operator make Attacking Midfielder's region 21 separate with low back region 22 time concentrate on top 33a and nearExtremely narrow and small position like this, therefore, Attacking Midfielder's region 21 becomes easy especially with separating of low back region 22.
In addition, at Attacking Midfielder's region 21 and low back region 22 at abutment 30 in peeling off or be not easy to peel offIn the situation of state, by operator's power, make to form Attacking Midfielder's region 21 and/or low back region at the periphery at abutment 30The thermoplastic synthetic fiber (not shown) who extends across with abutment 30 fracture in the fiber of 22 nonwoven, thus canAttacking Midfielder's region 21 is separated with low back region 22. Abutment 30 size on longitudinal A or on horizontal B is all little,Week length, and linearly arrange and formed row 40, therefore, in this case, Attacking Midfielder's region 21 and low back region22 separation is also arranged side by side with imaginary straight line 35, roughly successfully carries out linearly. If Attacking Midfielder's region 21 and/or rear waistlineThe quality of the per unit area of the fibroplastic nonwoven that is 0.1～4dtex by fiber number that region 22 is used is little, 9～15g/m2Scope, with quality than compared with its large nonwoven, should be less at the fiber of the periphery fracture at abutment 30, its pointFrom sometimes becoming more smooth.
The diaper 10 that can so successfully separate Attacking Midfielder's region 21 and low back region 22, is suitable as health softnessThe baby at low monthly age and the diaper that child uses use. If with the size of diaper, be following size: in Fig. 2 fromBe positioned at the waistline elastic component 44 of topmost of Attacking Midfielder's region 21 to the waistline elasticity of topmost that is positioned at low back region 22Size till member 54, parallel with center line P-P is in the scope of 300～530mm.
Fig. 5, the 6th, represents the amplification of the VI part in figure and Fig. 5 identical with Fig. 2 of an example of embodimentFigure. In Fig. 5, show the mode stretching, extension diaper 10b different from stretching diaper 10a in side seam region 25. Except the partyFormula, can also obtain and the diaper 10 that stretches the profile that the same Fig. 1 of having of diaper 10a illustrates for example according to stretching diaper 10b. ?Stretch in diaper 10b, side seam region 25 has upper section 40a, mid portion 40b and below part 40c, mid portion40b accounts at least 1/4 in the total length of side seam region 25 on longitudinal A. Upper section 40a and below part 40c be exceptBe formed with the part that is also formed with the row at the abutment 70 of appending outside the abutment 30 that Fig. 2,3 illustrates for example, and upper section40a and below part 40c account for respectively the scope of 1/10 to 1/2 in the total length of side seam region 25 on longitudinal A, more preferablyFor accounting for 1/10 to 1/4 scope. The abutment 70 of appending preferably has and the same or analogous shape in abutment 30, is positioned at laterallyThe size of B is no more than the side seam region 25 of 3mm, and the size m of longitudinal A at abutment 70 is no more than 2mm, laterally the size w of BIn the scope of 1.5～3mm, on longitudinal A, adjacent abutment 70 minimum is each other separated the scope of size n at 2～5mm. ThisSample, the side seam region 25 of stretching diaper 10b up part 40a and below part 40b has the row at abutment 30 and chases afterThe row at the abutment 70 adding. In addition, although do not illustrate, stretching in diaper 10b, in mid portion 40b, also can,The abutment 70 that arow is arranged abutment 30 and appended.
Mother, diaper 10 being worn in to infant with it time, wants sometimes to strut greatly waistline with two hands as far as possible and opensMouth 27. The stronger power that now, make Attacking Midfielder's region 21 separate with low back region 22 temporarily acts on side seam region25 upper section 40a. The abutment of appending 70 that is formed at Fig. 5,6 upper section 40a is in order to prevent such situationUnder Attacking Midfielder's region 21 adopt with separating of low back region 22. The abutment 70 of wherein, appending preferably reduces as far as possibleThe area at each abutment, the number in side seam region 25, the front waistline district with obstruction free in the time taking off this diaper 10Territory 21 separates with low back region 22. In addition, in the stretching, extension diaper 10b illustrating for example at Fig. 5,6, also at side edge part 24,26Form non-seam area 29. Although the size R of the non-seam area 29 in Fig. 6 is less than the size Q in side seam region 25, alsoCan implement the present invention in the size R mode larger than size Q.
In addition, in diaper 10, in the time wearing diaper 10, infant's leg can be stuck in leg and enclose the periphery of opening 28 sometimesPortion, the masterpiece that make Attacking Midfielder's region 21 separate with low back region 22 is used in the below part 40c of side edge part 24,26. In addition,If the wearer's of diaper 10 leg does not stop activity, to make Attacking Midfielder's region 21 sometimes also can with the power that low back region 22 separatesAct on below part 40c. The abutment of appending 70 of stretching the below part 40c of diaper 10b is in order to prevent such feelingsAttacking Midfielder's region 21 under condition adopts with separating of low back region 22. But, the abutment of appending of below part 40c70 preferably reduce the area at each abutment, number in side seam region 25 too as far as possible, become de-preventingObstruction when lower diaper 10. If compare with the diaper 10 obtaining according to stretching, extension diaper 10a, obtaining according to stretching diaper 10bDiaper 10 in, compared with stretching diaper 10a, side edge part 24 and the upper section 40a of side edge part 26 in side seam region 25And/or bonding area in the part 40c of below increases, the Attacking Midfielder's region 21 in the time taking off diaper 10 and low back region 22Separate and correspondingly become difficult, but in this case, at least 1/4 mid portion in the total length that accounts for side seam region 2540b, also the same with the diaper 10 obtaining from stretching, extension diaper 10a, can make Attacking Midfielder's region 21 and low back region 22 along sidePortion's seam region 25 successfully separates, and therefore, mother etc. think the diaper of easily taking off. But, if necessary, of the present inventionThe abutment 70 of appending also can be arranged in row in the total length in side seam region 25. And also can in the present invention,Form the reinforcement of strengthening with engaging of side edge part 26 offside edge 24 with connecing in the outside of the horizontal B in side seam region 25Chalaza, this reinforcement is preferably formed in the outside in side seam region 25 with abutment, and is just only formed on waistline opening 27The extremely narrow and small scope of below till 25mm and till leg enclose opening 28 directly over the extremely narrow and small scope of 25mm.
