About opaque liquid piece 11, as long as it can cover the part without opaque liquid piece 11 in built-in body 200 203 entirety, then its front-rear direction and size in width direction and position can suitably determine.In general, about liquid-tight Property piece 11, in the case of two Splittable of exterior, preferably as shown in Figure 8 the most narrow part of the width of built-in body 200 ( Illustrate form in the case of, be built-in body 200 overall with 200x) width direction in the range of be provided with narrower overall with 11x The opaque liquid piece, in the case where exterior is one-piece type, preferably as shown in Figure 12 in exterior body 12 and built-in body 200 The larger side of the width of width narrowest part (being exterior body 12 in form is illustrated), width narrowest part width direction In the range of, which is provided with narrower overall with 11x.In addition, the overall with 11x of opaque liquid piece 11 is preferably than built-in Big more than the 10mm of overall with of the part 203 without opaque liquid piece 11 of body 200.Particularly, in order to improve anti-leakage, vertical In the case that body rivel portion 60 has the root portion 65 of the side for the back side for being fixed in built-in body 200, it is preferred that the root Part 65 and opaque liquid piece 11 have the lap of more than 5mm in the direction of the width.Moreover, form is such as shown, In form of the three-dimensional rivel portion 60 containing waterproof membrane 64 in root portion 65, it is preferred that the waterproof membrane of root portion 65 and impermeable Fluidity piece 11 has the lap of more than 5mm in the direction of the width.

The front-rear direction size 11y of opaque liquid piece 11 as shown in Figure 8 with the front-rear direction size of absorption component 50 It is identical, as long as opaque liquid piece is arranged in the range of the front-rear direction identical with absorption component 50, but it is preferred that impermeable Fluidity piece is longer than absorption component 50 as shown in Fig. 9 (a), Fig. 9 (b) and is arranged on the front-rear direction model bigger than absorption component 50 In enclosing.Opaque liquid piece 11 can also be with the sheets 13 shown in Fig. 9 (a), Fig. 9 (b) in the same manner in waist opening to exterior body It turns back on the inside of 12F, 12B, still, as shown in figure 8, being only arranged at the feelings in the outside of exterior body 12F, 12B in opaque liquid piece Under condition, the edge of the waist opening WO sides of opaque liquid piece 11 is preferably made to be detached relative to waist opening WO sides between crotch, particularly preferred position In the position than waist W by side between crotch.

Particularly in the case of two Splittable of exterior as the method, front side exterior body 12F and rear side exterior body 12B The position detached on front-rear direction LD corresponds to the supply position of urine, and is the especially important region of anti-leakage.In we In formula, although opaque liquid piece 11 is located at the outside of exterior body 12F, 12B, in such two segmenting structure of exterior, preceding At the position that side exterior body 12F and rear side exterior body 12B are detached on front-rear direction LD, can by opaque liquid piece 11 not every It exterior body 12F, 12B and covers the part 203 without opaque liquid piece 11 in built-in body 200, therefore, urine is not easy It is impregnated in exterior body 12F, 12B and is exuded to outside.Particularly, have in three-dimensional rivel portion 60 and be fixed in built-in body 200 In the case of root portion 65 on the side of back side, in front side, exterior body 12F and rear side exterior body 12B are on front-rear direction LD At the position of separation, the root portion 65 in three-dimensional rivel portion 60 and opaque liquid piece 11 can directly be bonded together, so as to Enough form the excellent structure of anti-leakage.Moreover, because aftermentioned sheets 13 spreads front side exterior body 12F and rear side exterior body 12B It is configured, therefore is formed as throughout the continuous appearance of front side exterior body 12F and rear side exterior body 12B and skin sense of touch.

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.It is widely used in polyethylene or polypropylene as the plastic film with penetrability Etc. in olefin-based resins mixing inorganic filler and after being molded slice, it is obtained micro- more along an axis or two axis directions extensions Permeability plastic film.

The pattern (including the personage to paint with single-point pattern) for decoration, user are attached on opaque liquid piece 11 Method is shown or the marks such as producer or name of product, feature functionality are shown etc. decoration print using auxiliary, the functions such as size Brush.In the case of the resin film high using opacity to opaque liquid piece 11, need that outer surface is implemented to print, still, Such as in the case of the resin film for using the transparency high, 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 by hot-melt adhesive 11H is used as On the outside lamella 12S of the exterior body of opposed faces, in addition, in the case of 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, make to stand like that in mode as shown Body rivel portion 60 includes in root portion 65 under the form of waterproof membrane 64, in waterproof membrane 64 and the opaque liquid piece of root portion 65 11 parts overlapped, all adhesive layers between waterproof membrane 64 and opaque liquid piece 11 (are one layer in adhesive layer In the case of be the layer) width preferably in more than 3mm, particularly preferably in more than 5mm, in the situation that adhesive layer is multilayer Under, the part that preferably coincides with all adhesive layers, the width of 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 in the same manner with exterior body.

(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, product external surfaces as also can forming 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 form is illustrated, the entire outer surface of opaque liquid piece 11 is covered by a sheets 13, but can also be formed For：Sheets 13 etc. is set respectively in front portion and rear body section, the entire outer of opaque liquid piece 11 is covered by multiple sheets Surface.

The front-rear direction range of sheets 13 is not particularly limited, can be identical or bigger with opaque liquid piece 11 Range.Label 13y in figure represents 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 towards waist opening WO extensions, 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 and rear of sheets 13 are removed with clothes friction.

Particularly, form is such as shown, if sheets 13 is extended on the end of waist opening WO sides 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 turn back on the inside of exterior body 12F, 12B identically with sheets 13, but it is preferred that：Form is such as shown, opaque liquid The edge of the waist opening WO sides of piece 11 is detached relative to waist opening WO sides 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 with 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 represent 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 is significantly and as unnatural appearance.In contrast, If sheets 13 is arranged in the range 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.If that is, 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 stripping.In addition, if the side end of sheets 13 holds Easily with the leg friction of wearer, then peeling-off worry higher, and also there is following worry：Step difference causes skin sense of touch Deteriorate.In contrast, do not allow if the side end of sheets 13 is higher than surrounding positioned at the region with absorption component 50, i.e. rigidity Easily deform and be not easy and 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 of being adhered to opposed faces, which does not allow easily peelable.Also, it in order to be formed as such structure, needs built-in The back side of the both sides of absorption component 50 in body 200 sets the 64 grade opaque liquids of waterproof membrane in aforementioned three-dimensional rivel portion 60 Piece 11, and make to be set to the width of the opaque liquid piece 11 in the outside of exterior body 12F, 12B to narrow.

The processing method of the combination (crosslinking) of type or fiber for the fiber of non-woven fabrics that is used for sheets 13, it is not special It does not limit, the non-woven fabrics with the material identical 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-wall-element model 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 having The part that the region of decorating printing 27 coincides is individual layer, but in the region other than this or two layers, such as such as Figure 22 It is shown or：By turning back to width direction WD center sides 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 in the hole for not having perforation positive and negative can be used, but in this mode, if Sheets is the apertured nonwoven cloth in the hole 14 for being provided with multiple perforation positive and negatives at spaced intervals, then not only gas permeability is improved, And the visual confirmation of the decorating printing of opaque liquid piece also becomes good, therefore preferably.

In the case of 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 there is the region that hole 14 is not present at the both ends of the width direction WD of sheets 13, if passed through Hole 14 is opened up 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 vertical direction is kept out of the way and cause hole 14 periphery 14e warpages 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 what is wound with being relaxed State can form gauffer or folding line so as to worry in the aporate area of both sides.Therefore, it is intended that mode is like that throughout width 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 Enough using non-porous material, be also capable of the forming part of arbitrarily control hole, but there are it is following the problem of：Due to wanting entrance hole shape Forming apparatus, thus entire manufacture become it is huge and so that expense or the burden of maintenance become larger, in addition, being difficult in high-speed production lines Adjust hole shape and flexibility.It is therefore preferable that form 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 Shown in 17 (b) outside such long hole shape, such circular shown in Figure 17 (c), Figure 17 (e), Figure 17 (d) institutes 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. In the case that the shape in hole 14 is shape longer in one direction as long hole shape, ellipse, rectangle, diamond shape etc., Full-size on length direction is preferably maximum sized less than 2.5 times on the direction vertical with length direction.In addition, In the case that the shape in hole 14 is shape longer in one direction, it is desirable to the length direction in hole 14 is front-rear direction LD, but Can also be width direction WD or tilted direction.

About the area and area occupation ratio in each hole 14, if suitably determine, but area preferably about 0.2~ 2.5mm²(particularly preferably about 0.5~1.5mm²), area occupation 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 planar alignment repeatedly is preferred, In addition to the rectangle clathrate as shown in Figure 17 (a) or the hexagonal lattice shape shown in Figure 17 (b) (these are also referred to as staggered), figure The rectangular grid shape shown in square lattice shape, Figure 17 (d) shown in 17 (c), the parallel body grid shown in Figure 17 (e) are (as schemed Showing like that, in the way of the groups of multiple parallel rectangle nematics is provided with 2 groups in a manner of crossing one another) shape etc. is (including making these The faciation of rectangle nematic is for shapes of the front-rear direction LD to be less than 90 degree of angle tilt) as regularly repeat except, Can make hole 14 group (group unit arrangement either rule can also be it is irregular, can also be decorative pattern or word Shape etc.) regularly repeat.

It about the front-rear direction interval 14y in hole 14 and width direction interval 14x, 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.Particularly, if as shown in Figure 17 (d), make being shaped so as in front-rear direction LD for hole 14 Upper elongated shape, also, with front-rear direction interval 14y narrow the full-size 14L on the front-rear direction LD than hole 14 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 significantly increased, flexibility or bulkiness will not be damaged, in addition, important front and back during fabrication Upward piece tensile strength will not reduce, and be therefore preferred.

As the cross sectional shape in hole 14, can be any one in following manner：1st mode, wherein, 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 parts of tilting height 14i and tilts height 14j most Low part, wherein, the minimum parts of height 14j that tilt are hung down with the highest opposed parts of the tilting height 14i Opposed opposed part on straight direction.From the viewpoint of being improved gas permeability, it is desirable to be to have the part in hole 14 thicker than surrounding The 2nd mode and the 3rd mode, particularly, 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 being determined using light microscope, in the state of pressure is not applied) 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.

Punching hole that hole 14, which can be edge, to be formed by the cut-out end of fiber or non-punching hole as follows (fibre density of periphery is high)：There's almost no the cut-out end of fiber in the edge in hole 14, and the non-punching hole be pass through by Needle is extended and is formed between being inserted into 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 shape longer in one direction, the fiber of the periphery 14e in hole 14 by the insertion of needle Outward or vertical direction is kept out of the way and so that the periphery 14e in hole 14 is tilted, also, the opposed part on the length direction in hole 14 The tilting height i directions more vertical than with length direction on opposed part tilting height j high.In above-mentioned 2nd mode and the 3rd In mode, the edge of part that the periphery 14e about hole 14 is tilted to surface, there is also its fibre density 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, but can not also be welded together.

About the inner surface of sheets 13, when sheets 13 and the front-rear direction range of opaque liquid piece 11 and width direction range 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, with reference to Figure 10), in the case where sheets 13 is made to be more than opaque liquid piece 11 as shown in Figure 3, the sheets Inner surface with the part that opaque liquid piece 11 overlaps 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 with main region with exterior body.Particularly, on the outside lamella 12S be non-woven fabrics and In the case of the position consistency of the position of the both side edges of opaque liquid piece 11 and the both side edges of sheets 13, 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 formed 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 of the sheets 13 with hole 14, a preferred bonded structure is：Such as Figure 18 (a)-Figure 18 (d) institutes Show, in the bonding region of at least one party of the inner surface and the outer surface of sheets 13, the periphery in the region than being overlapped with hole 14 Portion 14i is by there is no hot-melt adhesive 13H, other than the peripheral part 14i in the region overlapped with hole 14, hot melt adhesion at center side Agent 13H exists in continuous planar.Since the peripheral part 14i in the region than being overlapped with hole 14 is by viscous there is no hot melt at center side Agent 13H is met, therefore gas permeability is excellent.In addition, there is such Nian Jie knot only on the face of the opposite side in the face with skin contact Structure, at the part with such bonded structure, it is not easy to tacky skin sense of touch is generated due to hot-melt adhesive 13H, and And the periphery 14e in hole 14 is reliably fixed to opposed faces.

As representative adhering state, following state may be exemplified out：As shown in Figure 18 (a), Figure 18 (b), with There is no hot-melt adhesive 13H in the region that hole 14 overlaps, and other than the region overlapped with hole 14, hot-melt adhesive 13H is in company Continuous planar exists；And as shown in Figure 18 (c), Figure 18 (d), hot-melt adhesive 13H is in the peripheral part in the region overlapped with hole 14 14i overflows, and still, the peripheral part 14i in the region than being overlapped with hole 14, which is leaned on, is not present hot-melt adhesive 13H at center side, Other than the peripheral part 14i in the region 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 overlapped with hole 14 is the part of the periphery 14e of access hole 14, and Sheets 13 has certain thickness, therefore, even if hot-melt adhesive 13H is made to be overflowed in the part as the latter, but only It is carried out at be bonded part with the face of the opposite side in the face of skin contact, in one opposite with bonding plane with hand contact sheets 13 During the face of side, hot-melt adhesive 13H is hardly directly contacted.Also, at the peripheral part 14i in the region overlapped with hole 14 , the spilling width of hot-melt adhesive 13H preferably the thickness of sheets 13 less than half and in about below 0.5mm.In addition, Wish hot-melt adhesive 13H is not present in more than 80% part of the area in the region 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 to the warpage portion of 11 side warpage of opaque liquid piece, then the hole 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.So as in the face only with the opposite side in the face of skin contact 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 as support column relative to opposed faces 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 easily to be floated (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, easily generates gap), therefore, around hole 14 Portion 14e is reliably bonded, and becomes incomplete bonding (substantive bond area is smaller) in region in addition, thus Excellent flexibility and soft sense can be obtained.

Such bonded structure can manufacture by the following method：By hot-melt adhesive in the case of without using air The bonding plane of apertured nonwoven cloth is coated in continuous planar, and is bonded 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 of without 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 mouth (hole), and the enlarged open is to the periphery in the hole of apertured nonwoven cloth.If that is, using this Then as the variation as shown in Figure 19 in arrow, hot-melt adhesive 13H is being coated in continuous planar for the adhering method of sample 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 of part overlapped with the hole 14 of apertured nonwoven cloth of 13H 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) Example, there is no hot-melt adhesive 13H in the major part in hole 14, and also there is no the hot-melt adhesives caused by air 13H comes 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 in the case of without using air being in continuous planar coating hot-melt adhesive Ground uses：Slot coating makes applicator head (mold) be contacted with the bonding plane of apertured nonwoven cloth, from the end for being set to applicator head It is applied along the gap extruding and hot melting bonding agent in CD directions (direction vertical with MD directions (conveying direction of manufacturing line))；Or The slot coating of person's non-contact type, in a state that the bonding plane for making applicator head (mold) from apertured nonwoven cloth floats, from setting The gap extruding and hot melting bonding agent along CD directions in the end of applicator head, by the official post of the conveying speed with apertured nonwoven cloth Hot-melt adhesive extends, very thin membranaceous so as to be applied as.

Sticking condition can suitably determine, but in order to which the hot-melt adhesive 13H overlapped with hole 14 is made rapidly to be moved to 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 following condition.

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 during hot-melt adhesive is applied to apertured nonwoven cloth：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) or：Use by opaque liquid piece 11 be installed on built-in body 200 with While toward structure, extend in the longitudinal direction across setting is located than the outside lamella 12S in exterior body 12F, 12B in the outer part Sheets 13.In the case of setting decorating printing 27 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 detached 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 the visual confirmation of the decorating printing 27 of opaque liquid piece 11 can be improved Property.In addition, since sheets 13 extends to rear side exterior body 12B at least from the exterior body 12F of front side on front-rear direction LD, As throughout the continuous appearance of front side exterior body 12F and 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 built-in body 200 When across locating to set the sheets 13 extended in the longitudinal direction in the outer part than the outside lamella 12S in exterior body 12F, 12B In the case of, without sheets 13 is made to cover opaque liquid piece 11 to the part covered by exterior body 12F, 12B of opaque liquid piece 11, 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 make the rear of sheets 13 to be located at rear than absorption component 50 by the position of front side be also a preferred mode.That is, sheets 13 leading edge and rear if located in the low part of rigidity or easily deforms, then is easily detached 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 detached or are shelled from opposed faces From then the gauffer of sheets 13 and the boundary part of exterior body easily becomes obvious and becomes unnatural appearance.In contrast, it covers The leading edge and rear of piece 13 is if located in the region with absorption component 50, i.e. rigidity is higher without easily deforming than around In region, then it is difficult to detach 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 apparent and becomes unnatural appearance.

About decorative pattern plate, other than being only set as opaque liquid piece 11 or：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 Shown in 25 (b) dedicated printed sheet 25 is decorated in appropriate position setting like that.Label 25H represents to paste printed sheet 25 Hot-melt adhesive.The position of setting printed sheet 25 is not particularly limited, and still, such as form is such as shown, if formed as Following form：By printed sheet 25 be set to than the outside lamella 12S in exterior body 12F, 12B in the outer part place and on the outside of it into One step is bonded sheets 13, then becomes the almost entirety for the part with decorating printing that printed sheet 25 is only covered by sheets 13 Form, the visual confirmation of decorating printing become excellent.

It as the base material of printed sheet 25, as long as being suitble to printing, is just not particularly limited, such as paper or the trees such as crepe paper can be used Adipose membrane etc..In the case where 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 crape rate is set as 10% or so to make 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)) value that calculates of/(circumferential speed of Flying Dutchman) × 100 (%).Make For the decorating printing of printed sheet 25, the pattern (including the personage to paint with single-point pattern) for decoration, user may be used The functions such as method or use auxiliary, size are shown or the appropriate dresses such as the marks such as producer or name of product, feature functionality are shown Decorations printing.

＜ is about manufacturing method ＞

At least both side ends of sheets 13 is enable to pass through the glued structures of hot-melt adhesive 13H 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 Go out the vertical view of the variation of assembled state, two figures, which are mapped, to be drawn.

It, will be in MD side 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 CD directions, thus shape Into exterior shoestring 120 of the elastomeric element between inside lamella and outside lamella.In exterior shoestring 120, become outer The part for filling body is repeatedly continuous in the MD direction in a manner that its width direction WD is consistent with the MD directions in manufacturing line.Scheming Show in form and be separately formed with：Include 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 the 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 performed to the exterior shoestring 120 of formation as needed, in MD directions On separate defined interval, will be positioned at the part CT overlapped later with built-in body 200 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 built-in body installation procedure 302, separated in the cd direction with the configuration identical with the unfolded state of diaper on one side The parallel conveying exterior shoestring 120 in compartment of terrain, will simultaneously in parallel be produced in a known manner by other manufacturing lines on one side Unfolded state under built-in body 200 be engaged in the position as each exterior body on the exterior shoestring 120 successively, thus Form following built-in assembly：It is continuous in the MD direction with unfolded state as the part of each diaper.These engage and consolidate Surely it can be carried out by the appropriate means 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 composition 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, in the situation for illustrating two Splittable of exterior as form Under, in the exterior shoestring 120 for including the part as front side exterior body 12F and include as rear side exterior body 12B's It is after the determined position of position relationship between partial exterior shoestring 120, i.e. after built-in body installation procedure 302 Preferably.

It is in waist turns back process 304, the end 122 on the outside of the CD directions of exterior shoestring 120 is central to CD directions 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 about subsequent process is not illustrated, but can manufacture Breeches type disposable diaper by well known method. That is, in folding process, built-in body 200 will be mounted on exterior shoestring 120 and be mounted with built-in group after sheets 13 Body is filled to the doubling of CD directions, doubling shoestring is consequently formed, is engaged in side in cutting off process, 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.

Be characterized in that, in sheets bonding process 303, on one side by the shoestring 130 of band-like continuous sheets along it 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 MD side The sheets 13 of the cut-out is adhered to the opposite with the composition 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, can be not present hot-melt adhesive overflow ground by the side end of sheets 13 firmly It is adhered to opposed faces.

Particularly, mode is such as shown, the resin film bonding process being appended below before sheets bonding process 303 305 form is a preferred form：The shoestring of opaque liquid piece being made of resin film of decorating printing will be implemented 111 be continuously adhered in the MD direction the shoestring 130 of sheets on the bonding plane of exterior shoestring 120.Label 313 It represents the bonding plane mutually Nian Jie with the shoestring 111 of opaque liquid piece of shoestring 130 of the 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 the shoestring 130, in face of exterior shoestring 120 of sheets of the agent coated on the shoestring 111 for being bonded with opaque liquid piece 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 It fills on the face of the opposite side in composition surface of 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 on by the shoestring 111 of the opaque liquid being made of resin film piece After the shoestring of sheets 13, cut each sheets 13 and be pasted on exterior shoestring 120, therefore, each cover after cut-out The rigidity of piece 13 correspondingly increases, and gas permeability is remarkably decreased with resin film, 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 realize 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 of the back side for the absorption component that opaque liquid piece 11 is set in built-in body 200, Opaque liquid piece 11 can be pasted in the manufacturing process of built-in body 200 (not shown), glues opaque liquid piece 11 so as 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, sheets can be used as using pre-processed apertured nonwoven cloth 13, but in order to cut down material cost, it is preferred to be processed in manufacturing line.But implementing perforation processing to non-woven fabrics In the case of, 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 cause 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 perform the perforation process 306 for sheets 13, then it can realize stabilization Perforation processing, therefore preferably.
