The material of opaque liquid piece 11 is not particularly limited, such as may be exemplified out by olefin-baseds such as polyethylene or polypropylene The plastic foil of the compositions such as resin.For opaque liquid piece 11, it is preferred to use from the viewpoint of prevent it is bored it is wet and it is preferable to use Material with opaque liquid and penetrability.As the plastic film with penetrability, it is widely used in polyethylene or polypropylene Etc. mix inorganic filler in olefin-based resins and form slice after, extend along an axis or two axis directions it is obtained micro- more Permeability plastic film.

It is attached on opaque liquid piece 11 for the pattern (including the personage to paint with single-point pattern) of decoration, user Method is shown or the marks such as producer or name of product, feature functionality are shown etc. decoration print using the functions such as auxiliary, size Brush.To opaque liquid piece 11 using the high resin film of opacity, need that outer surface is implemented to print, still, Such as using the high resin film of the transparency, Printing Department can be also set to the inner surface of opaque liquid piece 11.

In the case where exterior is one-piece type, the inner surface of opaque liquid piece 11 is adhered to conduct by hot-melt adhesive 11H On the outside lamella 12S of the exterior body of opposed faces, in addition, in the case where two Splittable of exterior, the interior table of opaque liquid piece 11 Face is adhered to the outside lamella 12S and built-in body 200 of front side exterior body 12F and rear side exterior body 12B by hot-melt adhesive 11H The back side.About opaque liquid piece 11, it is preferred that in the main region other than its rear ends, at least two side ends Portion's (preferably width direction is whole) is continuously bonded in product length direction.Moreover, making to stand like that in mode as shown Body rivel portion 60 includes under the form of waterproof membrane 64, in the waterproof membrane 64 and opaque liquid piece of root portion 65 in root portion 65 11 parts being overlapped, all adhesive layers between waterproof membrane 64 and opaque liquid piece 11 (are one layer in adhesive layer In the case where be the layer) width preferably in 3mm or more, particularly preferably in 5mm or more, the case where adhesive layer is multilayer Under, the part preferably to coincide with all adhesive layers, the width for the part which coincides be preferably 3mm with On.The rear ends of opaque liquid piece 11 are not bonded relative to exterior body 12F, 12B, but can also be between the rear ends Region bonds together with exterior body in the same manner.

(sheets)

The entire outer surface of opaque liquid piece 11 is covered by the sheets 13 being made of non-woven fabrics.Even if as a result, by liquid-tight Property piece 11 is set to the outside of exterior body 12F, 12B, is also capable of forming product external surfaces as cloth.In addition, since decoration prints Brush 27 is arranged at the opaque liquid piece 11, therefore, not only without using dedicated decorating printing 27, although moreover, being energy Enough decorating printings 27 arrived across 13 fluoroscopic observation of sheets, but decorating printing 27 is close to product external surfaces, can more clearly into Row visual confirmation.

In diagram form, the entire outer surface of opaque liquid piece 11 is covered by a sheets 13, but also may be constructed Are as follows: sheets 13 etc. is respectively set in front portion and rear body section, covers the entire outer of opaque liquid piece 11 by multiple sheets Surface.

The front-rear direction range of sheets 13 is not particularly limited, can be identical as opaque liquid piece 11 or bigger Range.Label 13y in figure indicates the overall length of sheets 13.For example, it may be: in front portion F and rear body section B at least One side, as shown in Fig. 9 (a), Fig. 9 (b), sheets 13 extends towards waist opening WO, around waist opening WO edge and to exterior body It turns back on the inside of 12F, 12B.The leading edge of sheets 13 and rear do not expose in product external surfaces as a result, and appearance becomes good.Separately Outside, it is not easy to which there is a situation where the leading edge of sheets 13 and rears to remove with clothes friction.

In particular, form is such as shown, if sheets 13 extends on the end of the waist opening side WO of built-in body 200, The return portion 12r of the outside lamella 12S of exterior body 12F, 12B can then be omitted.In this case, opaque liquid piece can be made 11 identically as sheets 13 to turning back on the inside of exterior body 12F, 12B, but it is preferred that: form as shown is such, opaque liquid The edge of the waist opening side WO of piece 11 is separated relative to waist opening WO to side between crotch.

The width direction range of sheets 13 is not particularly limited, if it is considered that aftermentioned manufacturing method, then preferably such as Figure 10 It is shown identical as opaque liquid piece 11 like that, but can also be the range wider than opaque liquid piece 11 as shown in Figure 3.In figure Label 13x indicate sheets 13 overall with.Wherein, it if sheets 13 extends to stretching region A2, is also formed in sheets 13 Shrinkage creases, therefore, the side end of sheets 13 is easily peeled off or gauffer obviously becomes unnatural appearance.In contrast, If sheets 13 is arranged within the scope of the width direction of non-telescoping region A1, in the range of entire sheets 13 gauffer all compared with Few, aesthetics is excellent, therefore preferably.In addition, if the both side edges of sheets 13 are located at the position of the both side edges than absorption component 50 At the position of width direction center side, then more preferably.That is, if the side end of sheets 13 be located at the low part of rigidity or Person easily deforms, even if being then adhered to opposed faces it can also happen that removing.In addition, if the side end of sheets 13 holds Easily with the leg friction of wearer, then peeling-off worry is higher, and there is also following worries: step difference makes skin sense of touch Deteriorate.In contrast, do not allow if the side end of sheets 13 is higher than surrounding positioned at region, the i.e. rigidity with absorption component 50 It easily deforms and is not easy in the region of the leg friction of wearer, then skin sense of touch is not easy to deteriorate, also, in side end In the case where being adhered to opposed faces, which does not allow easily peelable.Also, it in order to be formed as such structure, needs in interior dress The waterproof membrane 64 that three-dimensional rivel portion 60 above-mentioned is arranged in the back side of the both sides of absorption component 50 in body 200 waits opaque liquids Piece 11, and the width of the opaque liquid piece 11 in the outside for being set to exterior body 12F, 12B is made to narrow.

The processing method of the combination (crosslinking) of type or fiber for the fiber of the non-woven fabrics for sheets 13, it is not special It does not limit, non-woven fabrics identical with the material of exterior body 12F, 12B can be properly selected, it may be desirable to using hot-wind nonwoven cloth. In addition, the weight of the unit area of sheets 13 preferably about 20~40g/m².In addition, the thickness of sheets 13 be preferably 0.3~ 1.0mm, in the case where inside piece layer 12H and outside lamella 12S is non-woven fabrics, the thickness of sheets 13 can be than inside lamella 12H and the outside respective thickness of lamella 12S are thin, but thickness preferably more respective than inside lamella 12H and outside lamella 12S is thick.Separately On the one hand, in the case where inside piece layer 12H and outside lamella 12S is non-woven fabrics, if inside lamella 12H, outside lamella 12S It is consistent on width direction WD with the fiber orientation of sheets 13, then tensile elongation in length and breadth (or tensile elongation is in length and breadth Than) close, therefore, when deformation has occurred in use, inside lamella 12H, outside lamella 12S and sheets 13 can be integrally Deformation, the side end of sheets 13 are difficult to remove, therefore preferably.About sheets 13, it is preferred that with opaque liquid piece 11 or have The part that the region of decorating printing 27 coincides is single layer, but in the region other than this, is also possible to two layers, such as such as Figure 22 It is shown, it is also possible to: by turning back to width direction WD center side by the both sides of sheets 13 or separately pasting non-woven fabrics, thus Double-layer structure is formed, elastomeric element 13G is installed along front-rear direction LD between the layer, enables the part in the longitudinal direction It is flexible.

For sheets 13, the non-porous non-woven fabrics for not having the hole of perforation front and back sides can be used, but in this mode, if Sheets is the apertured nonwoven cloth for being provided with the hole 14 of multiple perforation front and back sides at spaced intervals, then not only gas permeability is improved, And the visual confirmation of the decorating printing of opaque liquid piece also becomes well, therefore preferably.

To sheets 13 using apertured nonwoven cloth, can have at a part of the front-rear direction LD of sheets 13 There is the region there is no hole 14, but if considering the effect of raising gas permeability, it would be desirable that be integrally provided with hole throughout front-rear direction 14.On the other hand, in the mode that the both ends of the width direction WD of sheets 13 have the region that hole 14 is not present, if passed through Open up hole 14 based on the method other than the punching of cutter progress, then as described later, the fiber meeting of the periphery 14e in hole 14 Outward or the periphery 14e warpage in hole 14 is kept out of the way and made to vertical direction, so that the thickness of hole area becomes than nothing Bore region is thick, and therefore, when with the material of reeling condition keeping sheets 13, the part of aporate area becomes to wind with being relaxed State, so that gauffer or folding line can be formed in the aporate area of both sides by worrying.Therefore, it is intended that mode spreads width like that as shown Degree direction WD's is formed integrally with hole 14.Also, by forming hole in sheets 13 in the manufacturing process of diaper, as a result, can Non-porous material is enough used, the forming part of arbitrarily control hole is also capable of, but is had the following problems: due to wanting entrance hole shape Forming apparatus, therefore entire manufacture becomes huge and the burden of expense or maintenance is become larger, in addition, being difficult in high-speed production lines Adjust hole shape and flexibility.It is therefore preferable that forming porose material using throughout entire front-rear direction and entire width direction To be manufactured.

It about the flat shape (opening shape) in each hole 14, can suitably set, in addition to being set as Figure 17 (a), figure Outside such long hole shape shown in 17 (b), such circular shown in Figure 17 (c), Figure 17 (e), Figure 17 (d) institute may be arranged as Show the arbitrary shape such as the polygons such as such ellipse, triangle, rectangle, diamond shape and star, cloud shape.About each The size in hole 14, is not particularly limited, and the full-size 14L on front-rear direction LD is preferably 0.4~1.8mm, particularly preferably Full-size 14W on 0.8~1.3mm, width direction WD is preferably 0.3~1.5mm, particularly preferably 0.5~1.0mm.? The shape in hole 14 is as long hole shape, ellipse, rectangle, diamond shape etc. in one direction in the case where longer shape, Full-size on length direction is preferably maximum sized 2.5 times or less on the direction vertical with length direction.In addition, The shape in hole 14 is in one direction in the case where longer shape, it is desirable to the length direction in hole 14 is front-rear direction LD, but It is also possible to width direction WD or tilted direction.

About the area and the area ratio in each hole 14, if suitably determine, but area preferably about 0.2~ 2.5mm²(particularly preferably about 0.5~1.5mm²), the area ratio is preferably about 1.0~15.0% (particularly preferably about 5.0~10.0%).

About the planar alignment in hole 14, can suitably determine, still, regularly duplicate planar alignment is preferred, In addition to hexagonal lattice shape shown in the rectangle clathrate as shown in Figure 17 (a) or Figure 17 (b) (these are also referred to as staggered), figure Rectangular grid shape shown in square lattice shape, Figure 17 (d) shown in 17 (c), parallel body grid shown in Figure 17 (e) are (as schemed Show like that, in the way of the group of multiple parallel rectangle nematics is provided with 2 groups in a manner of crossing one another) shape etc. (including make these The faciation of rectangle nematic is for front-rear direction LD in the shape of the angle tilt less than 90 degree) as regularly repeat except, Can making the group in hole 14, (arrangement of group unit can also be decorative pattern or text either rule is also possible to irregular Shape etc.) regularly repeat.

It about the front-rear direction interval 14y and width direction interval 14x in hole 14, can suitably determine, but in view of saturating Gas, it is desirable to which they are separately positioned in the range of 0.5~8mm, it is therefore highly desirable that they are separately positioned on to the model of 1~5mm In enclosing, if be averaged to front-rear direction interval 14y and width direction interval 14x, preferably their average value is set In the range of 1~5mm.In particular, if making being shaped as in front-rear direction LD for hole 14 as shown in Figure 17 (d) Upper elongated shape, also, with the full-size 14L on the front-rear direction LD than hole 14 narrow front-rear direction interval 14y preceding Being listed on width direction WD for the hole 14 arranged in rear direction repeats at a prescribed interval, and the width direction interval in hole 14 14x it is bigger than full-size 14L on the front-rear direction LD in hole 14 (more preferably 3 times of the width direction size 14W in hole 14 with On), then gas permeability can be improved significantly, will not damage flexibility or bulkiness, in addition, important front and back during fabrication Upward piece tensile strength will not reduce, and be therefore preferred.

It as the cross sectional shape in hole 14, can be such as any one under type: the 1st mode, wherein such as Figure 14 (a)- Shown in Figure 14 (c), the thickness of non-woven fabrics is thinning with the edge from surrounding's access hole 14 in hole 14, and the edge in hole 14 is located at nonwoven The centre of the thickness direction of cloth；2nd mode, wherein as shown in Figure 15 (a)-Figure 15 (c), the periphery 14e in hole 14 is to face side Warpage, and it is generally uniform to tilt height 14h；And the 3rd mode, wherein as shown in Figure 16 (a)-Figure 16 (c), around hole 14 Portion 14e is to face side warpage, and periphery 14e has the highest opposed part tilting height 14i and tilts height 14j most Low part, wherein the minimum part height 14j that tilts is hung down with the highest opposed part tilting height 14i Opposed opposed part on straight direction.From the viewpoint of improving gas permeability, it is desirable to be to have the part in hole 14 thicker than surrounding The 2nd mode and the 3rd mode, in particular, in the 3rd mode, due to hole 14 periphery 14e tilting height 14i, 14j it Gap that is poor and being formed helps to improve gas permeability, is therefore preferred.In the 2nd and the 3rd mode, tilting height 14g, 14h, 14i (apparent height determined using optical microscopy, in the state of not applying pressure) preferably about 0.2~ 1.2mm, in the 3rd mode, highest tilting height 14i is preferably about 1.1~1.4 times of minimum tilting height 14j.

Hole 14 can be the punching hole that edge is formed by the cutting end of fiber, be also possible to non-punching hole as follows The fibre density of periphery (high): there's almost no the cutting end of fiber in the edge in hole 14, and the non-punching hole be pass through by It extends and is formed between needle insertion fiber.The former is suitble to above-mentioned 1st mode, and the latter is suitble to above-mentioned 2nd mode, the 3rd mode.Example Such as, if forming the hole 14 of longer shape in one direction, the fiber of the periphery 14e in hole 14 by the insertion of needle Outward or vertical direction keeps out of the way and the periphery 14e in hole 14 is tilted, also, the opposed part on the length direction in hole 14 Tilting height i than with the tilting height j high of the opposed part on the vertical direction of length direction.In above-mentioned 2nd mode and the 3rd In mode, the edge for the part that the periphery 14e about hole 14 is tilted to surface, there is also its fibre densities than surrounding portion Divide low situation, but preferably equal extent or higher.Additionally, it is desirable that the fiber of the periphery 14e in hole 14 is fused to each other one It rises, however, you can also not be welded together.

About the inner surface of sheets 13, when the front-rear direction range and width direction range of sheets 13 and opaque liquid piece 11 When consistent, the inner surface of the sheets is only adhered to opaque liquid piece 11 (for width direction range by hot-melt adhesive 13H Consistent form, referring to Fig.1 0), in the case where making sheets 13 be greater than opaque liquid piece 11 as shown in Figure 3, the sheets The part being overlapped with opaque liquid piece 11 of inner surface opaque liquid piece 11, the cover are adhered to by hot-melt adhesive 13H The part that the never liquid-permeable sheet 11 of the inner surface of piece exceeds is adhered to exterior body by hot-melt adhesive 13H.

About sheets 13, in the main region other than rear ends (2~10mm), at least by both side ends, excellent Choosing is by the integral adhesive of width direction WD in opposed faces, and in this case, the side end of sheets 13 is adhered to opposed faces, therefore, Boundary seamlessly realize integration and unobtrusively, therefore preferably.The rear ends of sheets 13 are not glued relative to exterior body 12F, 12B It connects, but can also bond together identically as main region with exterior body.In particular, on the outside lamella 12S be non-woven fabrics and In the case where the position consistency of the both side edges of the position and sheets 13 of the both side edges of opaque liquid piece 11, for the interior table of sheets 13 For face, in the region other than its rear ends, at least both side ends are adhered to liquid-tight by hot-melt adhesive 13H Property piece 11, also, for the inner surface of opaque liquid piece 11, in the region other than its rear ends, at least two Side end is adhered to exterior body 12F, 12B by hot-melt adhesive 11H, and in this case, the both side ends of sheets 13 are across by setting The opaque liquid piece 11 that adipose membrane is constituted is glued to the outside lamella 12S being made of non-woven fabrics, therefore the both side ends of sheets 13 Engagement with outside lamella 12S becomes secured.

In the case where sheets 13 with hole 14, a preferred bonded structure are as follows: such as Figure 18 (a)-Figure 18 (d) institute Show, the periphery in the bonding region of at least one party of the inner surface and the outer surface of sheets 13, in the region than being overlapped with hole 14 Hot-melt adhesive 13H, other than the peripheral part 14i in the region being overlapped with hole 14, hot melt adhesion is not present in portion 14i at center side Agent 13H exists in continuous planar.Since there is no hot melts to glue at center side by the peripheral part 14i in the region than being overlapped with hole 14 Agent 13H is met, therefore gas permeability is excellent.In addition, only having such bonding knot on the face of the opposite side in the face contacted with skin Structure, at the part with such bonded structure, it is not easy to tacky skin sense of touch is generated because of hot-melt adhesive 13H, and And the periphery 14e in hole 14 is reliably fixed to opposed faces.

As representative adhering state, may be exemplified out following state: as shown in Figure 18 (a), Figure 18 (b), with Hot-melt adhesive 13H is not present in the region that hole 14 is overlapped, other than the region being overlapped with hole 14, hot-melt adhesive 13H is in company Continuous planar exists；And as shown in Figure 18 (c), Figure 18 (d), peripheral part of the hot-melt adhesive 13H in the region being overlapped with hole 14 14i overflows, and still, hot-melt adhesive 13H is not present in the peripheral part 14i in the region than being overlapped with hole 14 at center side, Other than the peripheral part 14i in the region being overlapped with hole 14, hot-melt adhesive 13H exists in continuous planar.The former state is special Desired state, still, since the peripheral part 14i in the region being overlapped with hole 14 is the part of the periphery 14e of access hole 14, and Sheets 13 has certain thickness, therefore, even if overflowing hot-melt adhesive 13H in the part, but only At the part that the face of the opposite side in the face contacted with skin is bonded, in one opposite with bonding plane with hand contact sheets 13 When the face of side, hot-melt adhesive 13H is hardly directly contacted.Also, at the peripheral part 14i in the region being overlapped with hole 14 , the spilling width of hot-melt adhesive 13H preferably the thickness of sheets 13 less than half and in about 0.5mm or less.In addition, Wish that there is no hot-melt adhesive 13H in 80% or more part of the area in the region being overlapped with hole 14.

The cross sectional shape in the hole 14 in sheets 13 is not particularly limited, but if making the periphery in hole 14 as described above 14e becomes the hole to the warpage portion of 11 side warpage of opaque liquid piece, then observed with the face of the never opposite side of 11 side of liquid-permeable sheet Diameter is compared, and never the aperture of 11 side of liquid-permeable sheet observation is smaller.To in the face of the opposite side in the face only contacted with skin At the part being bonded, at the face of the opposite side with hand contact bonding plane, it is not easy to touch hot-melt adhesive 13H.Separately Outside, warpage portion supports sheets 13, therefore, the non-porous nothing with identical weight per unit area relative to opposed faces as support column Woven fabric, which is compared, becomes more bulk, and gas permeability is also more excellent.In addition, due to the region other than the periphery 14e in hole 14 In, sheets 13 is bonding with opaque liquid piece 11 to be easy to float (although being drawn in Figure 18 (a)-Figure 18 (d) as hot-melt adhesive 13H fills up the space between piece very close to each otherly, but the coating amount of essence is less, is easy to produce gap), therefore, around hole 14 Portion 14e is reliably bonded, and becomes incomplete bonding (substantive bond area is smaller) in region furthermore, thus Excellent flexibility and soft sense can be obtained.

Such bonded structure can manufacture by the following method: in the case where not using air by hot-melt adhesive It is coated on the bonding plane of apertured nonwoven cloth in continuous planar, and bonds together with opposed faces.This method is based on following new hairs It is existing: if hot-melt adhesive to be coated on to the bonding plane of apertured nonwoven cloth in the case where not using air in continuous planar, Before being bonded with opposed faces, due to the surface tension of hot-melt adhesive, in the Kong Chong with apertured nonwoven cloth of hot-melt adhesive The center of the part of conjunction offers in mouth (hole), and the enlarged open is to the periphery in the hole of apertured nonwoven cloth.That is, if using this The adhering method of sample, then as changing shown in arrow, hot-melt adhesive 13H is being coated in continuous planar in Figure 19 Before being bonded after apertured nonwoven cloth and with object Part, due to the surface tension of hot-melt adhesive 13H, in hot-melt adhesive The center for the part of 13H being overlapped with the hole 14 of apertured nonwoven cloth offers mouth (hole) h, and opening h is extended to apertured nonwoven cloth Hole 14 periphery 14e.Therefore, after apertured nonwoven cloth is adhered to object Part, as shown in Figure 18 (a)-Figure 18 (d) Hot-melt adhesive 13H is not present in example in the major part in hole 14, the hot-melt adhesive caused by being also not present because of air 13H falls off or oozes out from hole 14, therefore, at the face of the opposite side with hand contact bonding plane, it is not easy to generate tacky flesh Skin sense of touch.

It, can be appropriate as the hole melt applicator for applying hot-melt adhesive in continuous planar in the case where not using air Ground uses: slot coating makes the bonding face contact of applicator head (mold) with apertured nonwoven cloth, from the end for being set to applicator head Gap extruding and hot melting bonding agent along the direction CD (direction vertical with the direction MD (conveying direction of manufacturing line)) is applied；Or The slot coating of person's non-contact type, in the state of floating applicator head (mold) from the bonding plane of apertured nonwoven cloth, from setting The gap extruding and hot melting bonding agent along the direction CD in the end of applicator head, by the official post of the conveying speed with apertured nonwoven cloth Hot-melt adhesive extends, to be applied as very thin membranaceous.

Sticking condition can suitably determine, but in order to be moved to the hot-melt adhesive 13H being overlapped with hole 14 rapidly The periphery 14e in hole 14 and the periphery 14e for being bonded hole 14 securely, it is desirable to meet at least one of condition below.

The melt viscosity (140 DEG C of temperature) of hot-melt adhesive: 3000~2600mpas

The melt viscosity (160 DEG C of temperature) of hot-melt adhesive: 1150~1550mpas

Temperature when to apertured nonwoven cloth coating hot-melt adhesive: 110~150 DEG C

For the coating amount of the hot-melt adhesive of apertured nonwoven cloth: 1.0~8.0g/m²

Sphere time (open time) after the coating of hot-melt adhesive: 0.1~1.0 second

As shown in Figure 23~Figure 25 (b), be also possible to: use by opaque liquid piece 11 be installed on it is interior dress body 200 with While toward structure, extend in the longitudinal direction across locate to be arranged in the outer part than the outside lamella 12S in exterior body 12F, 12B Sheets 13.In the case where decorating printing 27 are arranged to opaque liquid piece 11 in the form, if form uses like that as shown Two segmenting structure of exterior, and make the part with decorating printing 27 of opaque liquid piece 11 outside front side exterior body 12F and rear side Expose at the part that dress body 12B is separated on front-rear direction LD, then at the part covered using sheets 13 to it, can only wear It crosses the perspective of sheets 13 ground and sees decorating printing 27, therefore can be improved the visual confirmation of the decorating printing 27 of opaque liquid piece 11 Property.In addition, since sheets 13 at least extends to rear side exterior body 12B from the exterior body 12F of front side on front-rear direction LD, As throughout front side exterior body 12F and the continuous appearance of rear side exterior body 12B and skin sense of touch.

As shown in Figure 23~Figure 25 (b), using the same of the previous structure that opaque liquid piece 11 is installed on to interior dress body 200 When the sheets 13 extended in the longitudinal direction is set across place in the outer part than the outside lamella 12S in exterior body 12F, 12B In the case of, without making sheets 13 cover the part that opaque liquid piece 11 is covered to opaque liquid piece 11 by exterior body 12F, 12B, Therefore, as shown in Figure 25 (a), Figure 25 (b), make sheets 13 leading edge be located at than absorption component 50 leading edge by rear side position, And so that the rear of sheets 13 is leaned on the position of front side positioned at the rear than absorption component 50 is also a preferred mode.That is, sheets If 13 leading edge and rear are located at the low part of rigidity or easily deform, it is easy to separate from opposed faces, even if viscous Opposed faces are connected to, there is also peeling-off worries.Also, if the leading edge and rear of sheets 13 are separated or are shelled from opposed faces From then the gauffer of the boundary part of sheets 13 and exterior body is easy to become obvious and become unnatural appearance.In contrast, it covers If the leading edge and rear of piece 13 are located at region with absorption component 50, i.e. rigidly higher without easily deforming than around In region, then it is difficult to separate or remove from opposed faces, so as to prevent following situation: the side of sheets 13 and outside lamella 12S The gauffer of boundary part becomes obvious and becomes unnatural appearance.

Be also possible to other than being only set as opaque liquid piece 11 about decorative pattern plate: substitution sets decorating printing 27 This design of opaque liquid piece 11 is placed in or while decorating printing 27 is set to opaque liquid piece 11, such as Figure 23~figure At position appropriate, dedicated printed sheet 25 is decorated in setting like that shown in 25 (b).Label 25H is indicated for pasting printed sheet 25 Hot-melt adhesive.The position that printed sheet 25 is arranged is not particularly limited, and still, such as form as shown is such, if be formed as Following form: printed sheet 25 is set to locate in the outer part than the outside lamella 12S in exterior body 12F, 12B and on the outside into One step is bonded sheets 13, then becomes the almost entirety that the part with decorating printing of printed sheet 25 is only covered by sheets 13 Form, the visual confirmation of decorating printing become excellent.

As the substrate of printed sheet 25, as long as being suitble to printing, it is not particularly limited, the paper such as crepe paper or tree can be used for example Adipose membrane etc..Using crepe paper, thickness is preferably 100~150 μm, and density is preferably 100~200kg/m³.In this way The crepe paper of thickness and density can be by setting the weight of unit area as 10g/m²Above and sets crape rate and made as 10% or so It creates.Also, density can come out according to the weight and THICKNESS CALCULATION of unit area.In addition, crape rate is according to ((Yankee is dried The circumferential speed of cylinder)-(circumferential speed of take-up reel))/(circumferential speed of Flying Dutchman) × 100 (%) calculated value.Make It, can be using the pattern (including the personage to paint with single-point pattern) for decoration, user for the decorating printing of printed sheet 25 Method is shown or the dresses appropriate such as the marks such as producer or name of product, feature functionality are shown using the functions such as auxiliary, size Decorations printing.

< is about manufacturing method >

Enable at least both side ends of sheets 13 by hot-melt adhesive 13H glued structure according to such as Figure 20 (a), manufacturing method shown in Figure 20 (b) manufactures.That is, the manufacturing method includes exterior body assembling procedure (not shown), elasticity Component cut process 301, built-in body installation procedure 302, sheets bonding process 303, waist are turned back process 304, folding (not shown) Folded process and side (not shown) engagement cut off process.Also, Figure 20 (a) is the flow chart of manufacturing equipment, and Figure 20 (b) is to show The top view of the variation of assembled state out, two figures, which are mapped, to be drawn.

It, will be in the side MD in a manner of clamping the elastomeric element continuously fed in the MD direction in exterior body assembling procedure A upward continuous sheet material is folded or continuous two sheet materials will be fit together in the MD direction to the direction CD, thus shape At exterior shoestring 120 of the elastomeric element between inside lamella and outside lamella.In exterior shoestring 120, become outer Fill body part by its width direction WD and the direction MD in manufacturing line it is consistent in a manner of in the MD direction repeatedly and it is continuous.Scheming Show in form and be separately formed with: including the exterior shoestring of the part of the front side exterior body 12F as two Splittable of exterior 120；With the exterior shoestring 120 for including part as rear side exterior body 12B, but in the case where exterior is one-piece type, outside Fill shoestring 120 or one.

Next, elastomeric element cut off operation 301 is executed to the exterior shoestring 120 of formation as needed, in the direction MD On separate defined interval, the part CT being overlapped later with built-in body 200 will be located at by the disconnecting device 310 of heat embossing etc. The elastomeric element 121 at place is cut off, and at the CT of the part, becomes the substantially inoperative state of convergent force of elastomeric element 121.

In interior dress body installation procedure 302, separated in the cd direction with configuration identical with the unfolded state of diaper on one side Compartment of terrain conveys exterior shoestring 120 in parallel, will be produced simultaneously in parallel in a known manner by other manufacturing lines on one side Unfolded state under built-in body 200 be successively engaged in the position as each exterior body on the exterior shoestring 120, thus Form following built-in assembly: the part as each diaper is continuous in the MD direction with unfolded state.These engage and consolidate Surely it can be carried out by the means appropriate such as hot-melt adhesive.

In sheets bonding process 303, sheets 13 is adhered to exterior shoestring 120 at spaced intervals in the MD direction On the face of the side opposite with the joint surface of built-in body 200.If sheets bonding process 303 is more forward than folding process, but Since sheets 13 is spread from front portion F to rear body section B, the case where illustrating two Splittable of exterior as form Under, including to become the exterior shoestring 120 of the part of front side exterior body 12F and is including as rear side exterior body 12B It is after the determined position of positional relationship between partial exterior shoestring 120, i.e. after interior dress body installation procedure 302 Preferably.

It turns back in process 304 in waist, by the end 122 on the outside of the direction CD of exterior shoestring 120 to the direction CD center Side is turned back, also, elastomeric element 123 is continuously sandwiched to the lower section of the return portion in the MD direction.Thereby, it is possible to carry out waist The installation of portion's elastomeric element 17 and the formation of return portion 12r.

This subsequent process is not illustrated, but can manufacture Breeches type disposable diaper by well known method. That is, in folding process, it will be mounted with interior dress body 200 on exterior shoestring 120 and be mounted with the interior dress group after sheets 13 Body is filled to the doubling of the direction CD, doubling shoestring is consequently formed, engagement is cut off in process in side, becoming in doubling shoestring The exterior body of the exterior body of front portion and rear body section is bonded together at the part of the both sides of each diaper, and The boundary of each diaper cuts off the exterior body of front portion and the exterior body of rear body section, thus obtains each diaper.

It is characterized in that, on one side will be in the shoestring 130 of band-like continuous sheets along it in sheets bonding process 303 Continuous direction conveying, it is continuous in the MD direction by applying device 312 on its bonding plane in face of exterior shoestring 120 on one side Ground applies hot-melt adhesive, then, each sheets 13 is cut at spaced intervals in the MD direction using sliding knife 311, in the side MD The sheets 13 of the cutting is adhered to the opposite with the joint surface of built-in body 200 of exterior shoestring 120 by spaced up compartment of terrain On the face of side.It, can be on width direction WD continuously by hot-melt adhesive as a result, other than the rear ends of sheets 13 Until the lucky lateral margin for being applied to sheets 13, the spilling of hot-melt adhesive can be not present firmly by the side end of sheets 13 It is adhered to opposed faces.

In particular, mode is such as shown, the resin film bonding process being appended below before sheets bonding process 303 305 form is a preferred form: will implement the shoestring for the opaque liquid piece of decorating printing being made of resin film 111 be continuously adhered in the MD direction the shoestring 130 of sheets on the bonding plane of exterior shoestring 120.Label 313 Indicate the bonding plane mutually Nian Jie with the shoestring 111 of opaque liquid piece of the shoestring 130 by hot-melt adhesive coated on sheets On applying device.It is continuously that hot melt is viscous in the MD direction by applying device 312 as a result, in sheets bonding process 303 Connect agent be coated on be bonded with opaque liquid piece shoestring 111 sheets shoestring 130, it is in face of exterior shoestring 120 On bonding plane, then, each sheets 13 and opaque liquid piece 11 are cut at spaced intervals in the MD direction using sliding knife 311, The sheets cut 13 and opaque liquid piece 11 are adhered to exterior shoestring 120 at spaced intervals in the MD direction with it is interior On the face of the opposite side in the joint surface of dress body 200.In addition, in this case, the both side edges of the sheets 13 in product with it is impermeable The both side edges of fluidity piece 11 are consistent.Under the form, it is pasted in the shoestring 111 for the opaque liquid piece that will be made of resin film After the shoestring of sheets 13, cuts each sheets 13 and be pasted on exterior shoestring 120, therefore, each cover after cutting The rigidity of piece 13 is correspondingly increased with having resin film, and gas permeability is remarkably decreased, and therefore, is passing through sliding knife 311 such as figure When attracting holding is carried out shown in middle arrow like that and carrying out interruption stickup relative to exterior shoestring 120, shape and attracting holding Property stablize, can be realized stable stickup.

Although it is not shown, it may also be: it is not the shoestring that the shoestring 111 of opaque liquid piece is pasted on to sheets 130, but opaque liquid piece 11 is bonded on the exterior shoestring 120 before being bonded sheets 13, then from the opaque liquid on piece It is bonded sheets 13.In addition, in the case where the back side for the absorption component being set to opaque liquid piece 11 in interior dress body 200, Opaque liquid piece 11 can be pasted in the manufacturing process of interior dress body 200 (not shown), glue opaque liquid piece 11 to omit It is affixed on the shoestring 130 of sheets or the process of exterior shoestring 120.

In the case where sheets 13 is apertured nonwoven cloth, pre-processed apertured nonwoven cloth can be used as sheets 13, but in order to cut down material cost, it is preferred that processing is carried out in manufacturing line.But perforation processing is being implemented to non-woven fabrics In the case where, the speed of processing line is faster, is more difficult to steadily carry out high-precision processing.In this regard, in the manufacturing method of diagram form Sheets bonding process 303 in, due to cut off and be interrupted paste and make sheets shoestring 130 for sheets be bonded The feed speed of process 303 is slack-off, therefore, if form is like that in the sheets 13 for sheets bonding process 303 as shown Overpunch device 314 on the supply line of shoestring, and execute the perforation process 306 for being directed to sheets 13, then it can be realized stabilization Perforation processing, therefore preferably.
