(absorber)
Absorber 23 is made of lower layer absorber 23B and the upper layer absorber 23A being arranged in above lower layer absorber 23B Two-layer structure.
As lower layer absorber 23B and upper layer absorber 23A, the slim, acetate fiber with the product of paper pulp fiber can be used The aggregate or non-woven fabrics of the filiform of element etc. are substrate, the superabsorbent polymer of hybrid particles shape as needed etc. and progress Material obtained from fixed etc..The fiber areal densities and superabsorbent polymer of lower layer absorber 23B and upper layer absorber 23A Surface density can suitably determine that preferably fiber areal densities are respectively 140g/m2~230g/m2Left and right, furthermore it is preferred that high-absorbable The surface density of polymer is respectively 60g/m2~90g/m2Left and right.Inferior, root the case where being mixed with superabsorbent polymer particle According to needs, lower layer absorber 23B and upper layer absorber 23A can both integrally or individually by the package panels such as fold paper 24 (referring to Fig.1, Fig. 7, Fig. 9) cladding.
In addition, the shape of absorber 23 can be set to front part, relatively than rear section width is biggish band-like or long The proper shapes such as rectangular, trapezoidal, however, it is preferred to be formed as width comprising the prescribed portion between hip among the front-rear direction of portion C2 Lesser constriction 23n.It is preferred that the minimum widith W3 of constriction 23n is non-narrowed before and after constriction 23n 50%~65% or so of partial width (overall with of absorber 23) W2.In addition, setting diaper front end as 0%, diaper rear end When being 100%, preferably the front end of constriction 23n is located at 10%~25% range, and the rear end of preferably constriction 23n is located at The position (minimum widith position) as minimum widith W3 of 40%~65% range, preferably constriction 23n is located at 25% ~30% range.
In the case where absorber is set as two-layer structure, preferably make lower layer's absorber bigger, therefore, side as shown Formula forms absorber shape preferably by lower layer's absorber and its shape is set as above-mentioned narrow shape, about upper layer absorber Shape, be set as the rectangle narrower than the width of constriction 23n.
Absorber 23 extends to the rear side of portion C2 between hip from the front side of portion C2 between hip by portion C2 between hip, still, as long as from Rear side of the C2 setting in portion to portion C2 between hip between hip.Particularly in view of male's purposes, it is desirable to from scrotum configuring area The front side of C1 is arranged to rear side.Here, " scrotum configuring area C1 " indicates the front-rear direction region of the scrotum of configuration wearer, because This, front side becomes " region on front side of scrotum configuring area C1 ", and rear side becomes " region on rear side of scrotum configuring area C1 ". In general, the front-rear direction length of scrotum configuring area C1 is 80mm~100mm or so.
(the 1st mode of surface indentation forming region)
As feature, as shown in Figure 1 to 4, the width direction center of portion C2 between at least hip of lower layer absorber 23B Portion, lower layer's through portion 60 of the elongate of perforation (absorber is not present) extends along the longitudinal direction in a thickness direction, upper In layer absorber 23A, at least within the scope of front-rear direction corresponding with lower layer's through portion 60, it is provided with and penetrates through in a thickness direction The upper layer through portion 50 of (absorber is not present).Moreover, upper layer through portion 50, which has, is located at 60 top of lower layer's through portion and edge The middle section 51 for the elongate that front-rear direction extends and the width direction two sides of the rearward position towards the middle section 51 extend Expansion 52, a part that the lateral margin of expansion 52 becomes at least front side is located at outside width direction with towards rear side The shape of side.
In the absorber 23 of such two-layer structure, in the middle section 51 of lower layer's through portion 60 and upper layer through portion 50 Intersection (the 1st recess forming portion) absorber 23 is not present, (the 2nd is recessed at the position of the expansion 52 of upper layer through portion 50 Fall into forming portion) become the single layer structure of lower layer's absorber 23B, the outside of the expansion 52 of upper layer through portion 50 becomes upper layer suction The two-layer structure of acceptor 23A and lower layer absorber 23B.As shown in figs. 6-9, it under wearing state, is pressed from both sides in disposable urine napkin When compressed in the direction of the width between two legs (referring to the hollow arrow of Fig. 7, Fig. 9), on lower layer's through portion 60 and upper layer Absorber 23, therefore, lower layer's through portion 60 and upper layer through portion 50 is not present in the intersection of the middle section 51 of through portion 50 Both side edges approached according to decrement, disposable urine napkin surface formed stria 71.At this point, although power is closer to each other The single layer structure part 23w of the expansion 52 positioned at upper layer through portion 50, still, upper layer through portion 50 are also acted on direction Expansion 52 lateral margin become at least front side a part with towards rear side and be located at width direction on the outside of shape (that is, on right side, towards right rear ramp, in left side, towards left rear ramp), single layer structure part 23w is readily along conduct as a result, It is bent inwardly with the lateral margin of the expansion 52 of the upper layer through portion 50 of two-layer structure portion boundary, therefore, single layer knot Structure part 23w is bent inwardly relative to the two-layer structure part on the outside of its width direction, between the 23w of single layer structure part Without absorbing, body portion is recessed inwardly therewith, and as shown in Figure 6 and Figure 8, on the surface of disposable urine napkin, formation substantially boat-shaped is recessed Fall into 72.When on upper layer, the expansion 52 of through portion 50 is rectangle (i.e. the lateral margin of expansion 52 is U-shaped), such change Shape is difficult to happen.Moreover, the recess of such boat-shaped is easy to restore not only for the compression of width direction, and bend inwardly Single layer structure part 23w become wall and maintain the depth of recess, thus the maintenance of surface gap is excellent.In urination, Be excreted in the urine of the front side of the sunk area, be not absorbed and in the mobile part in surface with the biggish surface gap for stream Road and flow to rear side, absorbed in this process by the absorber of rear side 23.Therefore, it can be effectively prevented as existing issue Diffusion blocking caused by surface gap is less.
As long as the shape elongate of lower layer's through portion 60, in addition to mode width as shown is solid in the longitudinal direction Other than fixed rectangle, can also suitably change, for example, width change in the longitudinal direction (for example, width with towards after Side and expand) shape etc..The size of lower layer's through portion 60 can determine suitably, still, it is contemplated that use this disposable urine napkin Standard adult, preferably front-rear direction length 62 is 180mm~210mm or so.In addition, the width 61 of lower layer's through portion 60 can be with Appropriate to determine, still, if less wide, the shape maintenance in aftermentioned gap is more preferable, therefore, in general, preferably 20mm~40mm or so.It can be provided spaced apart multiple lower layer's through portions 60 in the direction of the width as is illustrated by figs. 11 and 12. In addition it is also possible to so that the front end of lower layer's through portion 60 is for example extended to front part F2 forwards as shown in (a) of Figure 29, if The dendritic through portion 66 from the oblique preceding and right tiltedly preceding extension to the left of the prolongation 65 is set, also, makes the rear end of lower layer's through portion 60 Rear section B2 is rearward for example extended to, the dendritic through portion from the prolongation 65 oblique rear and right tiltedly rear extension to the left is set 66, or as shown in (b) of Figure 29, be arranged from the front end of lower layer's through portion 60 and for example radially extend to front side portion forwards The radial extension 67 of point F2, also, after setting is rearward for example radially extended to from the rear end of lower layer's through portion 60 The radial extension 67 of side section B2.It is that prolongation is set in front and rear sides in the example shown in (a) of Figure 29, (b) 65 and dendritic through portion 66 or radial extension 67, it can also be only any one in front and back as shown in (c) of Figure 29, (d) Side's setting prolongation 65 and dendritic through portion 66 or radial extension 67, further, it is also possible to front and back change shape (example Such as, the either side in front and back is set as prolongation 65 and dendritic through portion 66, another party is set as radial extension 67 Deng).
Further, it is expected that lower layer's through portion 60 is arranged among the front-rear direction of lower layer absorber 23B, that is, it is set as The configuration that lower layer's through portion 60 does not penetrate before and after lower layer absorber 23B, thus, it is ensured that as the rigid of 23 entirety of absorber Property.
On the other hand, the size of upper layer through portion 50 can be determined suitably, front-rear direction length (the also phase of middle section 51 With) in addition to can in mode as shown it is identical as lower layer's through portion 60 other than, lower layer's through portion 60 can also be shorter or longer than.
It is desirable that, the width 55 of the middle section 51 of upper layer through portion 50 is 61 or more the width of lower layer's through portion 60, In view of expansion 52 to be ensured, it is desirable to be 1.2~1.5 times or so of the width 61 of lower layer's through portion 60.About tool Have the part of the expansion 52 of upper layer through portion 50 width 56 (width of the width and expansion 52 of middle section 51 Summation), it may be desirable to the shape maintenance of the size (the mainly height of wall) or recess that consider recess determines, desired Being is 1.5 times~2 times or so of the width 55 of middle section 51, more specifically, it is desirable to left for 36mm~120mm It is right.
The front-rear direction position of the expansion 52 of upper layer through portion 50 can suitably determine, can as shown in the example of the figure, It extends the rearward position of upper layer through portion 50 to side, front-rear direction middle position can also be made to be formed with extending to side. In addition it is also possible to be configured to, extend middle section 51 in the front side of the upper layer through portion 50 of diagramatic way, also, with rear side The 52 symmetrical shape in front and back of expansion of position, it is a pair of under wearing state in the additional expansion in its width direction two sides It is opposite (forming substantially hourglass-shaped recess) that the recess of boat-shaped clips stria 71 along its length.
In the middle section of upper layer through portion 50 51, the shape of the part of no expansion 52 is in addition to can be as shown Mode be that can also be suitably changed, such as width is in the longitudinal direction other than the rectangle fixed in the longitudinal direction of width Change the shape etc. of (for example, width expands with towards rear side).The shape of the expansion 52 of upper layer through portion 50 can be with It is the bending that lateral margin shape is diagramatic way, is also possible to the curve-likes such as arc-shaped.In diagramatic way, become in Between the boundary of part 51 be bottom, trapezoidal vertical with bottom of rear (includes expansion 52 and in-between middle section 51 Shape be pentagon), so that the lateral margin of expansion 52 at least front side a part with towards rear side and be located at width Shape on the outside of direction, but it is also possible to be set as it is trapezoidal shown in (a) of Figure 10 (comprising expansion 52 and among it in Between part 51 shape be hexagon).In addition, the shape of the lateral margin of expansion 52 for example can as shown in (a) of Figure 13, at For front side a part with the shape being located on the outside of width direction towards rear side and stepwise, or (b) institute such as Figure 13 Show, becomes a part of front side with the shape on the outside of width direction is located at towards front side, or as (c) of Figure 13 is shown as For rectangle.
The front-rear direction position of upper layer through portion 50 can suitably determine, however, it is preferred to which front end is (before middle section 51 End) it is identical as the front end of lower layer through portion 60 or be located at and lean on front side than it, but it is also possible to be located at than it by rear side.On in addition, The rear end of layer through portion 50 can be identical as the rear end of lower layer through portion 60 in mode as shown, however, it is preferred to positioned at leaning on than it Rear side is preferably placed at than it by front side.As the example of the latter, as shown in (b) of Figure 10, can enumerate makes lower layer's through portion 60 Rear end than upper layer through portion 50 extends to rear side and (label 60x shows it and prolongs than portion C2 extends to rear side between hip mode Extending portion point), in this case, when urine flows into the downside of upper layer absorber 23A by lower layer's through portion 60, to skin side It flows backwards and is blocked by upper layer absorber 23A.
In addition, shown in mode as shown, if the middle section 51 of upper layer through portion 50 extends to upper layer absorber 23A Front end and in the front opening of upper layer absorber 23A, the position of the front end of the front end and lower layer's through portion 60 of upper layer absorber 23A Set it is identical or be located at rear side, then when portion C2 is compressed in the width direction between hip, more by upper layer absorber 23A front side and more It is compressed by the front side of upper layer through portion 50 is easier, as a result, the recess of above-mentioned boat-shaped more easy to form, thus be preferred 's.
In illustrative example, at the position being overlapped with lower layer through portion, there is no absorbers, therefore, although the diffusivity of urine Well, still, it is easily deformed by the access that lower layer's through portion is formed and is possible to collapse.Therefore, as shown in Figure 14~Figure 16, when In the bottom of lower layer's through portion, setting promotes urine in the diffusion sheet 63 that front-rear direction is spread, and is easy to maintain by lower layer's through portion shape At access, promote urine by lower layer's through portion front-rear direction spread.
As long as diffusion sheet 63 can promote urine to spread in front-rear direction, the type of material is not particularly limited, in addition to It can be used other than non-woven fabrics or plastic sheet etc., the tow of the synthetic fibers such as Dichlorodiphenyl Acetate cellulose as needed can also be used (fibre bundle) carries out filiform aggregate obtained from fibrillation.
As the material fiber for constituting non-woven fabrics, in addition to the olefines such as polyethylene or polypropylene, polyesters, acyl can be used Except the synthetic fibers such as amine, the natural fibers such as regenerated fibers or cotton such as artificial silk, ammonia copper wire can also be used.It is preferred that nonwoven The surface density of cloth is 10g/m2~40g/m2Left and right.Using plastic sheet, in addition to can be used along front-rear direction court Surface is arranged except piece made of groove-like structure, can also use the piece etc. for bonding multiple plastic sheets and becoming hollow structure.This Outside, it can also use using non-woven fabrics as substrate, the superabsorbent polymer of hybrid particles shape as needed etc. is simultaneously fixed Made of material.
As fiber areal densities when using filiform aggregate, 30g/m can be set to2~120g/m2Left and right.Fiber number is 1dtex~16dtex, preferably 1dtex~10dtex, more preferably 1dtex~5dtex.Filiform can be crispaturaed fibre with right and wrong Dimension, it is preferred that being crinkled fibre.The degree of crispaturaing of crinkled fibre for example can be per inch 5~75, and preferably 10~50 It is a, more preferable 15~50 or so.In addition, mostly using the crinkled fibre uniformly crispaturaed.
Preferred diffusion piece 63 is arranged in the entirety of lower layer's through portion 60, but it is also possible to only at one in the front-back direction Point or width direction a part etc. be locally arranged.As long as the bottom of lower layer's through portion is arranged in diffusion sheet 63, in addition to Other than being arranged between top layer piece 22 and opaque liquid piece 21 in mode as shown, the table of top layer piece 22 can also be adhered to Face.In the case where diffusion sheet 63 are arranged, make to push up in the heating pressure processing such as implementation heat embossing processing above top layer piece 22 When synusia and diffusion sheet 63 directly or indirectly fuse, the rigidity of the bottom of lower layer's through portion is got higher, and is formed by lower layer's through portion Access be difficult to collapse, thus be preferred.
(solid fold in portion's between hip)
In addition, from the side of upper layer through portion 50, protrusion 42 outstanding prolongs along the longitudinal direction in the mode of diagram It stretches, also, is located at the front side of the protrusion 42 and the part of rear side and respectively becomes the non-rising portions 45 fixed with lodging state, Part between these non-rising portions 45 becomes revocable rising portions 46, moreover, the width direction two sides on surface are provided with Portion's solid fold between the hip on the rising portions 46 is fixed in the state that fold elastic flexible component 43 stretches along the longitudinal direction 40.Rising portions 46 are the effects as the convergent force of fold elastic flexible component 43 and from diaper as shown in double dot dash lines in Fig. 4 The part that surface rises.
It can also be not provided with portion's solid fold 40 between hip, still, due to upper layer through portion 50 and lower layer's through portion 60, between hip The uptake of portion C2 necessarily declines, and urine becomes easy movement, it is therefore preferable that being separately arranged except side solid fold 30.
Portion's solid fold 40 can be formed by installing dedicated on diaper surface between hip, however, it is preferred to as shown Mode makes bowing out than upper layer through portion 50 by the part of side and forming protrusion 42 for top layer piece 22.
In the case where portion's solid fold 40 between hip is arranged, on upper layer, the expansion 52 of through portion 50 is in the longitudinal direction (in other words, in the width of the expansion 52 of upper layer through portion 50 when between hip between the non-rising portions 45 of portion's solid fold 40 Degree direction position with the width position of the non-rising portions 45 of portion's solid fold 40 between hip when being overlapped), portion's solid fold between hip The convergent force of 40 fold elastic flexible component 43 effectively acts on single layer structure part 23w, can promote above-mentioned boat-shaped recess Formation, the shape maintenance of recess is improved, thus is preferred.But between hip portion's solid fold 40 non-rising portions 45 can also be located at the expansion 52 than upper layer through portion 50 by width direction center side or outside.
Further, it is expected that the width position of the cardinal extremity of the protrusion 42 of portion's solid fold 40 is as shown between hip Mode, separated from expansion 52 to side, but it is also possible to consistent with the lateral margin of expansion 52 or positioned at expansion In 52.Particularly most preferably between hip the width position of the cardinal extremity of the protrusion 42 of portion's solid fold 40 in the deployed state, Positioned at the outside of the expansion 52 of upper layer through portion 50 and the two-layer structure portion of upper layer absorber 23A and lower layer absorber 23B Above point.In addition, the width position of the end of the protrusion 42 of portion's solid fold 40 is in unfolded state most preferably between hip Under, positioned at the position passed through above the 23w of single layer structure part.By being set as these configurations, single layer structure part 23w readily along The lateral margin of expansion 52 as the upper layer through portion 50 with two-layer structure portion boundary and bend inwardly, therefore, boat The formation and maintenance of the recess 72 of shape become more preferable.
Percentage of elongation when as the material of the fold elastic flexible component 43 of portion's solid fold 40 between hip and fixing, Ke Yicong Use is properly selected in the range of material identical with side solid fold 30.Even if installing dedicated and shape on diaper surface At portion's solid fold 40 between hip and in addition top layer piece is set, and even if mode as shown penetrates through the ratio upper layer of top layer piece 22 Portion 50 bows out by the part of side and forms portion's solid fold 40 between hip, at least for the area between hip between portion's solid fold 40 Domain can also promote the expansion towards back side when top layer piece being especially at least set as waterproofness for surface indentation forming region It dissipates, thus is preferred.
The size in each portion of portion's solid fold 40 can be determined suitably between hip, still, it is contemplated that use this disposable urine The standard adult of piece, be divided into 150mm~180mm or so between the front-rear direction of preferably non-rising portions 45, preferably protrusion 42 60mm~80mm or so is divided between the width direction of cardinal extremity.Furthermore it is preferred that the rising portions 36 of side solid fold 30 are configured to compare Respectively forwardly side and rear extend the rising portions 46 of portion's solid fold 40 between hip.
In illustrative example, during fabrication, considers to convey material along the front-rear direction of disposable urine napkin and be assembled Common manufacture, portion's solid fold 40 reaches (but, the front and back of non-rising portions 45 overall length L of disposable urine napkin between hip Direction length is longer than side solid fold 30), but it is also possible to be set as before the expansion 52 with upper layer through portion 50 On the basis of rear direction range and from its front side nearby to the length near rear side.
(the 2nd mode of surface indentation forming region)
As shown in Figure 17~Figure 19, lower layer's through portion 60 of the lower layer absorber 23B of the 1st mode is substituted and to form thickness small In lower layer's thinning part 64 of surrounding (not penetrating through in a thickness direction), the advantage roughly the same with the 1st mode can also be brought.That is, In this 2nd mode, the intersection (the 1st recess forming portion) of the middle section 51 of lower layer's thinning part 64 and upper layer through portion 50 As the single layer structure of lower layer's thinning part 64, the position (the 2nd recess forming portion) of the expansion 52 of upper layer through portion 50 becomes The single layer structure being made of the part 23w other than the thinning part of lower layer absorber 23B, the expansion 52 of upper layer through portion 50 Outside becomes the two-layer structure of upper layer absorber 23A and lower layer absorber 23B.Under wearing state, pressed from both sides in disposable urine napkin When being compressed in the width direction between two legs, although power also acts on direction closer to each other positioned at upper layer through portion The single layer structure part 23w of 50 expansion 52, still, the single layer structure part 23w readily along as with two-layer structure The lateral margin of the expansion 52 of the upper layer through portion 50 of portion boundary and bend inwardly, single layer structure part 23w as a result, Bent inwardly relative to the two-layer structure part on the outside of its width direction, the part between the 23w of the single layer structure part with It is recessed inwardly, in the biggish recess of surface formation width of disposable urine napkin.Moreover, such recess is not only for width The compression in direction is easy to restore, moreover, the single layer structure part 23w bent inwardly becomes wall and maintains the depth being recessed, because This, the maintenance of recess or even the maintenance of surface gap are excellent.Therefore, it in this 2nd mode, in urination, is being excreted to In the urine of the front side of the sunk area, it is not absorbed and is flowed in the part of surface movement using the biggish surface gap as flow path To rear side, absorbed in this process by the absorber of rear side 23.Therefore, it can be effectively prevented between the surface as existing issue Diffusion blocking caused by gap is less.
The thickness of lower layer's thinning part 64 is not particularly limited, can be set to the thickness of the part other than thinning part 10%~ 50% or so, in general, it can be set to 1mm~5mm or so.Lower layer's thinning part is not limited by its forming method, for example, It, can also be by processing (root that through-thickness is compressed in addition to can be by making surface density lower than surrounding come other than being formed According to needing to be heated) it is formed.
In addition, it is identical as the 1st mode inside comprising variation, as long as by lower layer's through portion 60 in the explanation of the 1st mode It is substituted for lower layer's thinning part 64, thus omits further instruction.
(the 3rd mode of surface indentation forming region)
As shown in Figure 21~Figure 22, make the upper layer through portion of above-mentioned 1st mode and the lower in shape of lower layer's through portion on the contrary, Identical advantage can also be brought.Label 80 in Figure 21~Figure 22 indicates upper layer through portion, and label 81 indicates upper layer through portion 80 Width, label 82 indicate upper layer through portion 80 front-rear direction length, label 90 indicate lower layer's through portion, label 91 expression under The middle section of layer through portion 90, label 92 indicate that the expansion of lower layer's through portion 90, label 95 indicate middle section 91 Width, label 96 indicate the width with the part of the expansion 92 of lower layer's through portion 90.In this 3rd mode, upper layer is passed through The intersection (the 1st recess forming portion) of logical portion 80 and the middle section 91 of lower layer's through portion 90, which becomes, is not present absorber 23 Structure, the position (the 2nd recess forming portion) of the expansion 92 of lower layer's through portion 90 become the single layer knot of upper layer absorber 23A Structure, the outside of the expansion 92 of lower layer's through portion 90 become the two-layer structure of lower layer's absorber 23B and upper layer absorber 23A. Under wearing state, when disposable urine napkin is sandwiched between two legs and is compressed in the width direction, although power is closer to each other Direction on also act on the single layer structure part 23w of expansion 92 positioned at lower layer's through portion 90, still, the single layer structure Part 23w readily along the lateral margin of the expansion 92 as lower layer's through portion 90 with two-layer structure portion boundary and it is inside Lateral bending folding, the single layer structure part 23w is bent inwardly relative to the two-layer structure part on the outside of its width direction as a result, Part between the 23w of the single layer structure part is recessed inwardly therewith, biggish recessed in the surface formation width of disposable urine napkin It falls into.Moreover, such recess is easy to restore not only for the compression of width direction, and the single layer structure part bent inwardly 23w becomes wall and maintains the depth being recessed, and therefore, the maintenance of recess or even the maintenance of surface gap are excellent.Therefore, at this In invention described in, in urination, in the urine for the front side for being excreted to the sunk area, it is not absorbed and mobile on surface Part flows to rear side using the biggish surface gap as flow path, is absorbed in this process by the absorber of rear side 23.Therefore, energy Enough it is effectively prevented the less caused diffusion blocking of surface gap as existing issue.
Though it is not illustrated, being the upper layer through portion 50 and lower layer's thinning part 64 that can also similarly make the 2nd mode It is lower opposite in shape.
In addition, it is identical as the 1st mode and the 2nd mode inside comprising variation, as long as saying the 1st mode and the 2nd mode Replacement up and down in bright, thus omit further instruction.
(the 4th mode of surface indentation forming region)
In the 1st~the 3rd mode, absorber is set as two-layer structure and forms surface indentation forming region, still, such as schemed Shown in 23~Figure 26, in the absorber of single layer structure, by the way that surface indentation forming region of the invention is arranged, can also it obtain Disposable urine napkin with same characteristic features.
More specifically, in the mode shown in Figure 23~Figure 26, the portion C2 between the hip of the absorber 23 of single layer structure Width direction central portion is provided with surface indentation forming region 231,232, which has along preceding Rear direction extend elongate the 1st recess forming portion 231 and towards the 1st recess forming portion 231 front-rear direction interposition It sets or the 2nd recess forming portion 232 of the width direction two sides of rearward position extension, the 2nd recess forming portion 232 is less than as thickness The thinning part of surrounding (not penetrating through in a thickness direction), the 1st recess forming portion 231 become the perforation penetrated through in a thickness direction Portion.
In the disposable urine napkin with such absorber 23, under wearing state, becomes disposable urine napkin and be sandwiched in Between two legs and in the width direction when compressed state, surface indentation forming region 231,232 with center in the width direction according to It is secondary to be deformed towards the mode being forced out on the outside of diaper, also, recess 71,72 is formed on the surface of diaper.At this point, in surface indentation In forming region 231,232, compared to the part being only made of the 1st recess forming portion 231, by the 1st recess forming portion 231 and the 2nd The width for the part that the forming portion 232 that is recessed is constituted goes out greatly the amount of the 2nd recess forming portion 232, thus the recess that formation width is bigger 72.Moreover, the biggish depressed section 72 of the width ensures a degree of rigidity because of thinning part, therefore, be recessed 72 shape It is excellent with the maintenance of depth or even the maintenance of surface gap.In urination, in the region that is excreted to the recess 72 and its preceding In the urine of side, it is not absorbed and flows to rear side using the biggish surface gap as flow path in the mobile part in surface, in the mistake It is absorbed in journey by the absorber of rear side 23.Therefore, it can be effectively prevented less caused as the surface gap of existing issue Diffusion blocking.
As shown in Figure 27 and Figure 28, the 1st recess forming portion 231 can not be set as through portion and be set as thickness less than the 2nd The thinning part for the forming portion 232 that is recessed.In the case where the 1st recess forming portion 231 is through portion, the diffusivity of urine is good, still, It is easily deformed by the access that the 1st recess forming portion 231 is formed and is possible to collapse.Therefore, by by the 1st be recessed forming portion 231 It is set as thinning part, makes it easy to the access for maintaining to be formed by the 1st recess forming portion 231, urine is promoted to pass through the 1st recess forming portion 231 spread in front-rear direction.
The thickness of 2nd recess forming portion 232 is not particularly limited, and can be other than surface indentation forming region 231,232 Part thickness 10%~50% or so, in general, can be 1mm~5mm or so.In addition, being recessed by the 1st In the case that forming portion 231 is set as thinning part, thickness is not particularly limited, and can be the thickness of the 2nd recess forming portion 232 10%~50% or so, in general, it can be 1mm~5mm or so.These thinning parts are not limited by its forming method, For example, what can also be compressed by through-thickness adds other than can be by forming surface density lower than surrounding Work (can also be heated as needed) is formed.
1st recess forming portion 231 can be set to size shape identical with lower layer's through portion 60 of the 1st mode.That is, the 1st As long as the shape elongate for the forming portion 231 that is recessed, the length fixed in the longitudinal direction in addition to mode width as shown It other than rectangular, can also suitably change, such as width changes (for example, width expands with towards rear side) in the longitudinal direction Shape etc..1st recess forming portion 231 size can suitably determine, still, it is contemplated that using this disposable urine napkin mark Quasi- adult, preferably front-rear direction length 231L is 180mm~210mm or so.In addition, the width 231W of the 1st recess forming portion 231 It can suitably determine, it is still, preferable to the shape maintenance of recess 72 if less wide, it is therefore, in general, excellent It is selected as 20mm~40mm or so.Can also in the same manner as lower layer's through portion 60 shown in Figure 11 and Figure 12, in the direction of the width every The standard width of a room in an old-style house is every the multiple 1 recess forming portions 231 of setting.
Further, it is expected that being set by the way that the 1st recess forming portion 231 to be arranged among the front-rear direction of absorber 23 For the 1st configuration that is not penetrated before and after absorber 23 of recess forming portion 231, thus, it can be ensured that whole as absorber 23 Rigidity.
2nd recess forming portion 232 can be set to the part with the expansion 52 with upper layer through portion 50 of the 1st mode Identical size shape.That is, the width 232W about the 2nd recess forming portion 232, it is desirable to consider that the size of recess 72 is (main If the height of wall) or the shape maintenance of recess 72 determine, it is desirable to the width 231W of the 1st recess forming portion 231 and The summation of the width 232W of 2nd recess forming portion 232 of its two sides is 1.5 times of width 231W of the 1st recess forming portion 231~ 2 times or so, be 36mm~120mm or so more specifically.
The front-rear direction position of 2nd recess forming portion 232 can suitably determine, can make the 1st recess as shown in the example of the figure The rearward position of forming portion 231 is extended to side, and front-rear direction middle position can also be made to be formed with extending to side.In addition, Though it is not illustrated, being that can also be formed as, extend the 1st recess forming portion 231 in the front side of the 2nd recess forming portion 232, Also, with the 232 symmetrical shape in front and back of the 2nd of rearward position recess forming portion, in additional 3rd recess in its width direction two sides Forming portion, under wearing state, the recess of a pair of of boat-shaped clips that stria is opposite (to be formed substantially hourglass-shaped recessed along its length It falls into).
The shape of 2nd recess forming portion 232 can be the bending that lateral margin shape is diagramatic way, be also possible to circular arc The curve-likes such as shape.In the mode of diagram, become with the boundary with the 1st recess forming portion 231 as bottom, rear is vertical with bottom Trapezoidal (shape comprising the 2nd recess forming portion 232 and the 1st in-between recess forming portion 231 is pentagon) so that the 2nd A part of at least front side of the lateral margin for the forming portion 232 that is recessed, which becomes, is located at the shape on the outside of width direction with towards rear side Shape however, it can be identical with expansion 52 shown in (a) of Figure 10 trapezoidal (comprising expansion 52 and among it 51 shape of middle section be hexagon).In addition, the shape of the lateral margin of the 2nd recess forming portion 232 for example can be with Figure 13's (a) similarly, a part for becoming front side is located at width direction with towards rear side to expansion 52 shown in stepwise The shape in outside, or with (b) of Figure 13 shown in the same manner as expansion 52, become a part of front side with towards front side And it is located at the shape on the outside of width direction, or become rectangle in the same manner as the expansion 52 of (c) of Figure 13.
In the example shown in Figure 23~Figure 26, at the position being overlapped with the 1st recess forming portion 231, there is no absorbers 23, therefore, although the diffusivity of urine is good, it is easily deformed by the access that the 1st recess forming portion 231 is formed and is possible to Collapse.Therefore, in the expansion copied the 1st mode and promote urine to spread in front-rear direction in the bottom setting of the 1st recess forming portion 231 When discrete piece 63, it is easy the access for maintaining to be formed by the 1st recess forming portion 231, promotes urine by the 1st recess forming portion 231 preceding Rear direction diffusion.About the material or variation of diffusion sheet 63, due to identical as the 1st mode, thus omit the description.
In the case where portion's solid fold 40 between hip is arranged in the same manner as the 1st mode, in the 2nd recess forming portion 232 preceding In rear direction between hip between the non-rising portions 45 of portion's solid fold 40 when (in other words, the 2nd recess forming portion 232 width Degree direction position with the width position of the non-rising portions 45 of portion's solid fold 40 between hip when being overlapped), portion's solid fold between hip The convergent force of 40 fold elastic flexible component 43 effectively acts on the 2nd recess forming portion 232, can promote the shape of above-mentioned recess At the shape maintenance of recess is improved, thus is preferred.But between hip portion's solid fold 40 non-rising portions 45 It can be located at and lean on width direction center side or outside than the 2nd recess forming portion 232.
Further, it is expected that the width position of the cardinal extremity of the protrusion 42 of portion's solid fold 40 is as shown between hip Mode, from the 2nd recess forming portion 232 to side separate, but it is also possible to it is consistent with the lateral margin of expansion 52 or be located at expansion It opens up in part 52.In addition, the width position of the end of the protrusion 42 of portion's solid fold 40 is being unfolded most preferably between hip Under state, in the position passed through above the 2nd recess forming portion 232.It is configured by these, the 2nd recess forming portion 232 is easy edge Its lateral margin and bend inwardly, therefore, be recessed 72 formation and maintenance become more preferable.Portion is vertical between other and the 1st mode hip Body fold 40 is identical, thus omits the description.
