In addition, in the three-dimensional fold sheet 31 of sidepiece, part 34 outside width in fore-and-aft direction entirety with diaper inner surface (in illustrated mode, for top layer sheet 22 surface and outer load 26 inner surface) bond become standing part 34, further, the part 32 of width center side becomes from the outstanding ledge 32 of this standing part.And, in the both ends of the fore-and-aft direction in this ledge 32, with the state of lodging and diaper surface (in illustrated mode, for top layer sheet 22 surface) bonding become non-rising portions 35, and, part between these non-rising portions 35 becomes the rising portions 36 not being fixed on diaper surface (in illustrated mode, being top layer sheet 22 surface).This rising portions 36 because of the effect of the contractility of the three-dimensional fold elastic flexible component 33 of sidepiece as shown in the double dot dash line of Fig. 4 from diaper surface (illustrated mode, for top layer sheet 22 surface) erect, become the part contacted with groin etc., it erects cardinal extremity 37 and is positioned at the standing part 34 of the three-dimensional fold sheet 31 of sidepiece and the boundary of ledge 32.

(plane fold)

At the fore-and-aft direction pars intermedia of flap portion, side SF, between the three-dimensional fold sheet 31 of sidepiece and opaque liquid sheet 21 (also can be between opaque liquid sheet 21 and outer load 26), along fore-and-aft direction, utilize hot-melt adhesive etc., the plane fold elastic flexible component 27 of elongate is fixed with extended configuration, due to the contraction of this plane fold elastic flexible component 27, in flap portion, side SF, form so-called plane fold.Due to this plane fold, the sidepiece of diaper carries out elastic telescopic and fits with lower limb week.

The number of the plane fold elastic flexible component 27 of the left and right sides can suitably determine, being preferably 1 ~ about 10, being more preferably 2 ~ about 5, when being set to many, preferably it is spaced apart about 2mm ~ 15mm, is particularly preferably about 6mm ~ 10mm.In addition, as each plane fold elastic flexible component 27, can use and be formed as thread, the normally used material such as the styrenic rubbers of strip, band shape etc., olefin rubber, urethane esters rubber, ester rubber, polyurethane, polyethylene, polystyrene, phenylethylene/butadiene, silicon, polyester, as fineness degree, be preferably about 500dtex ~ 1500dtex, be about 0.1mm ~ 3mm in the case of natural rubber, be particularly preferably about 0.5mm ~ 3mm.In addition, percentage of elongation during preferred each plane fold elastic flexible component 27 fixing is about 150% ~ 250%.

(absorber)

Absorber 23 is by lower floor absorber 23B and is arranged on the two-layer structure that the upper strata absorber 23A above lower floor absorber 23B forms.

As lower floor absorber 23B and upper strata absorber 23A, can use with the aggregation of the filament of long-pending slim, the cellulose acetate of paper pulp fiber etc. or non-woven fabrics for substrate, as required hybrid particles shape etc. superabsorbent polymer and to be fixed etc. and the material obtained.The fiber areal densities of lower floor absorber 23B and upper strata absorber 23A and the surface density of superabsorbent polymer can suitably determine, optimum fiber surface density is respectively 140g/m ²~ 230g/m ²left and right, in addition, the surface density of preferred superabsorbent polymer is respectively 60g/m ²~ 90g/m ²left and right.Inferior in the situation being mixed with superabsorbent polymer granule, as required, lower floor absorber 23B and upper strata absorber 23A can both be integratedly or individually coated by the package panel such as fold paper 24 (with reference to Fig. 1, Fig. 7, Fig. 9).

In addition, the profile of absorber 23 can be set to front part than the rear section band shape that relatively width is larger or rectangle, the suitable shape such as trapezoidal, but the established part preferably comprising the fore-and-aft direction centre of portion C2 between hip is formed as the less constriction 23n of width.Preferably the minimum widith W3 of this constriction 23n is about 50% ~ 65% of width (overall with of the absorber 23) W2 of the non-constriction be positioned at before and after constriction 23n.In addition, setting diaper front end as 0%, when diaper rear end is 100%, the front end of preferred constriction 23n is positioned at the scope of 10% ~ 25%, the rear end of preferred constriction 23n is positioned at the scope of 40% ~ 65%, and the position (minimum widith position) becoming minimum widith W3 of preferred constriction 23n is positioned at the scope of 25% ~ 30%.

When absorber is set to two-layer structure, preferably make lower floor's absorber larger, therefore, as illustrated mode, preferably utilize lower floor absorber to form absorber profile and its shape is set to and above-mentionedly narrow shape, about the profile of upper strata absorber, be set to the rectangle narrower than the width of constriction 23n.

Absorber 23 extends to the rear side of portion C2 between hip from front side portion C2 through between hip of portion C2 between hip, but, as long as be set to the rear side of portion C2 between hip from portion C2 between hip.Especially male's purposes is considered, it is desirable that, be set to rear side from the front side of scrotum configuring area C1.At this, " scrotum configuring area C1 " represents the fore-and-aft direction region of the scrotum of configuration wearer, therefore, becomes on front side of it in " region on front side of scrotum configuring area C1 ", becomes in " region on rear side of scrotum configuring area C1 " on rear side of it.Under normal conditions, the fore-and-aft direction length of scrotum configuring area C1 is about 80mm ~ 100mm.

(the 1st mode of surface indentation forming region)

As feature, as shown in Figure 1 to 4, at at least width central part of portion C2 between hip of lower floor absorber 23B, lower floor's breakthrough part 60 of the elongate of through (namely there is not absorber) extends along the longitudinal direction in a thickness direction, in the absorber 23A of upper strata, at least within the scope of the fore-and-aft direction corresponding with lower floor breakthrough part 60, be provided with the upper strata breakthrough part 50 of through (namely there is not absorber) in a thickness direction.And, upper strata breakthrough part 50 has and to be positioned at above lower floor's breakthrough part 60 and the mid portion 51 of the elongate extended along the longitudinal direction and the expansion 52 expanded towards the width both sides of the rearward position of this mid portion 51, and the lateral margin of expansion 52 becomes a part at least front side along with the shape be positioned at towards rear side outside width.

In the absorber 23 of such two-layer structure, absorber 23 is there is not in the intersection (the 1st is recessed to form portion) of the mid portion 51 of lower floor's breakthrough part 60 and upper strata breakthrough part 50, the position (the 2nd is recessed to form portion) of the expansion 52 of upper strata breakthrough part 50 becomes the single layer structure of lower floor absorber 23B, and the outside of the expansion 52 of upper strata breakthrough part 50 becomes the two-layer structure of upper strata absorber 23A and lower floor absorber 23B.As shown in figs. 6-9, under wearing state, when being sandwiched between two lower limbs and being compressed in the direction of the width (hollow arrow with reference to Fig. 7, Fig. 9) at disposable urine napkin, absorber 23 is there is not in the intersection of the mid portion 51 of lower floor's breakthrough part 60 and upper strata breakthrough part 50, therefore, the both side edges of lower floor's breakthrough part 60 and upper strata breakthrough part 50 is close according to decrement, forms stria 71 on the surface of disposable urine napkin.Now, although power also acts on the single layer structure part 23w of the expansion 52 being positioned at upper strata breakthrough part 50 on approximating direction, but, the part that the lateral margin of the expansion 52 of upper strata breakthrough part 50 becomes at least front side along with the shape be positioned at towards rear side outside width (namely, on right side, the oblique rear towards the right side, in left side, the oblique rear towards a left side), thus, single layer structure part 23w easily bends to the inside along the lateral margin of the expansion 52 as the upper strata breakthrough part 50 with two-layer structure portion boundary, therefore, single layer structure part 23w bends to the inside relative to the two-layer structure part outside its width, being thereupon recessed into the inside without absorber part between single layer structure part 23w, as shown in Figure 6 and Figure 8, the depression 72 of roughly boat-shaped is formed on the surface of disposable urine napkin.When the expansion 52 of upper strata breakthrough part 50 is rectangle (namely the lateral margin of expansion 52 is U-shaped), such distortion is difficult to occur.And the depression of such boat-shaped is not only easily restored for the compression of width, and the single layer structure part 23w bent to the inside becomes wall and maintains the degree of depth of depression, and thus the maintenance of surface gap is excellent.When urinating, in the urine of front side being excreted to this sunk area, not by absorbing the part of surface movement with this larger surface gap for stream and flow to rear side, absorbed by the absorber 23 of rear side in this process.Therefore, it is possible to effectively prevent the less diffusion blocking caused of surface gap as existing issue.

As long as the shape elongate of lower floor's breakthrough part 60, except the rectangle that such as illustrated mode width is fixed in the longitudinal direction, can also suitably change, (such as, width expands along with towards rear side) shape etc. that such as width changes in the longitudinal direction.The size of lower floor's breakthrough part 60 can suitably determine, but consider the standard adult using this disposable urine napkin, preferred fore-and-aft direction length 62 is about 180mm ~ 210mm.In addition, the width 61 of lower floor's breakthrough part 60 can suitably determine, but not too wide, the shape maintains in gap described later is better, therefore, under normal conditions, is preferably about 20mm ~ 40mm.Can as is illustrated by figs. 11 and 12, spaced apart in the direction of the width multiple lower floors breakthrough part 60 is set.In addition, also can as shown in (a) of Figure 29, the front end of lower floor's breakthrough part 60 is made forwards such as to extend to front part F2, arrange from this prolongation 65 left tiltedly before and the right side tiltedly before the dendritic breakthrough part 66 that extends, and, the rear end of lower floor's breakthrough part 60 is made rearward such as to extend to rear section B2, arrange from this prolongation 65 left tiltedly after and the dendritic breakthrough part 66 that tiltedly extends afterwards of the right side, or as shown in (b) of Figure 29, the radial extension 67 forwards such as extending to front part F2 from the front end of lower floor's breakthrough part 60 is radially set, and, the radial extension 67 rearward such as extending to rear section B2 from the rear end of lower floor's breakthrough part 60 is radially set.In the example shown in (a), (b) of Figure 29, that prolongation 65 and dendritic breakthrough part 66 or radial extension 67 are set in both sides, front and back, also can as shown in (c), (d) of Figure 29, any one party only in front and back arranges prolongation 65 and dendritic breakthrough part 66 or radial extension 67, in addition, shape can also be changed (such as in ground, front and back, any one party in front and back is set to prolongation 65 and dendritic breakthrough part 66, the opposing party is set to radial extension 67 etc.).

Further, it is expected that, in the middle of fore-and-aft direction lower floor's breakthrough part 60 being arranged on lower floor absorber 23B, be namely set to the configuration that lower floor's breakthrough part 60 does not penetrate in the front and back of lower floor absorber 23B, thus, guarantee the rigidity as absorber 23 entirety.

On the other hand, the size of upper strata breakthrough part 50 can suitably determine, fore-and-aft direction length (mid portion 51 is also identical) except can as identical with lower floor breakthrough part 60 in illustrated mode except, can also be shorter than or be longer than lower floor's breakthrough part 60.

It is desirable that, the width 55 of the mid portion 51 of upper strata breakthrough part 50 is the width more than 61 of lower floor's breakthrough part 60, considers and will guarantee expansion 52, it is desirable that, be about 1.2 ~ 1.5 times of the width 61 of lower floor's breakthrough part 60.About the width 56 (summation of the width of mid portion 51 and the width of expansion 52) of part of expansion 52 with upper strata breakthrough part 50, desirably consider that the size (mainly the height of wall) of depression or the shape maintains of depression decide, desirably, for 1.5 times ~ about 2 times of the width 55 of mid portion 51, more specifically, it is desirable that, be about 36mm ~ 120mm.

The fore-and-aft direction position of the expansion 52 of upper strata breakthrough part 50 can suitably determine, can as shown in the example of the figure, the rearward position of upper strata breakthrough part 50 be expanded to side, and fore-and-aft direction centre position also can be made to be formed to side expansion.In addition, also can be configured to, mid portion 51 is extended in the front side of the upper strata breakthrough part 50 of diagramatic way, and, with with the expansion 52 of rearward position before and after symmetrical shape, add expansion in its width both sides, under wearing state, the depression of a pair boat-shaped clips stria 71 relatively (forming roughly hourglass-shaped depression) along its length.

In the mid portion 51 of upper strata breakthrough part 50, there is no the shape of the part of expansion 52 except can be except the width rectangle of fixing in the longitudinal direction as illustrated mode, can also suitably change, such as width changes the shape etc. of (such as, width expands along with towards rear side) in the longitudinal direction.The bending of the shape of the expansion 52 of upper strata breakthrough part 50 can be lateral margin shape be diagramatic way also can be the curve-likes such as arc-shaped.In diagramatic way, become with the border with mid portion 51 as going to the bottom, trailing edge and go to the bottom vertical trapezoidal (shape comprising the mid portion 51 of expansion 52 and centre thereof is pentagon), make a part at least front side of the lateral margin of expansion 52 along with the shape be positioned at towards rear side outside width, but, also can be set to trapezoidal (shape comprising the mid portion 51 of expansion 52 and centre thereof is hexagon) shown in (a) of Figure 10.In addition, the shape of the lateral margin of expansion 52 such as can as shown in (a) of Figure 13, become a part for front side along with the shape be positioned at stepwise towards rear side outside width, or as shown in (b) of Figure 13, become a part for front side along with the shape be positioned at towards front side outside width, or become rectangle as shown in (c) of Figure 13.

The fore-and-aft direction position of upper strata breakthrough part 50 can suitably determine, but preferred front end (front end of mid portion 51) is identical with the front end of lower floor breakthrough part 60 or be positioned at than its forward side, but, also can be positioned at than its side rearward.In addition, the rear end of upper strata breakthrough part 50 can be as identical with the rear end of lower floor breakthrough part 60 in illustrated mode, but, be preferably placed at than its side or be preferably placed at than its forward side rearward.As the example of the latter, as shown in (b) of Figure 10, can enumerate and lower floor's breakthrough part 60 is extended and the mode (label 60x shows its extension) extended to rear side than portion C2 between hip to rear side than the rear end of upper strata breakthrough part 50, in this case, when urine flows into the downside of upper strata absorber 23A by lower floor's breakthrough part 60, the refluence to skin side is blocked by upper strata absorber 23A.

In addition, as shown in illustrated mode, if the mid portion 51 of upper strata breakthrough part 50 extend to upper strata absorber 23A front end and at the front opening of upper strata absorber 23A, the front end of upper strata absorber 23A is identical with the position of the front end of lower floor breakthrough part 60 or be positioned on rear side of it, when then between hip, portion C2 is in the width direction by compression, the front side of more top layer absorber 23A and the front side of more top layer breakthrough part 50 are more easily compressed, consequently, more easily form the depression of above-mentioned boat-shaped, because of but preferred.

In illustrative example, there is not absorber at the position overlapped with lower floor breakthrough part, therefore, although the diffusibility of urine is good, the path formed by lower floor's breakthrough part is easily out of shape and likely collapses.Therefore, as shown in Figure 14 ~ Figure 16, promote that urine is when the diffusion sheet 63 of fore-and-aft direction diffusion, easily maintains the path formed by lower floor's breakthrough part when the bottom at lower floor's breakthrough part is arranged, promote that urine is spread at fore-and-aft direction by lower floor's breakthrough part.

As long as diffusion sheet 63 can promote that urine spreads at fore-and-aft direction, the kind of material is not particularly limited, except using except non-woven fabrics or plastic sheet etc., the tow (fibre bundle) of the synthetic fibers such as Dichlorodiphenyl Acetate cellulose as required can also be used to carry out fibrillation and the filament aggregation obtained.

As the material fiber forming non-woven fabrics, except can using the synthetic fibers such as the olefines such as polyethylene or polypropylene, polyesters, amide-type, the natural fibers such as the regenerated fiber such as artificial silk, ammonia copper wire or Cotton Gossypii can also be used.The surface density of preferred non-woven fabrics is 10g/m ²~ 40g/m ²left and right.When using plastic sheet, except can use channel-shaped structure is set along fore-and-aft direction towards surface sheet except, the multiple plastic sheet of bonding can also be used and become the sheet etc. of hollow structure.In addition, can also use with non-woven fabrics is substrate, as required the superabsorbent polymer of hybrid particles shape etc. the material to be fixed etc.

As fiber areal densities during use filament aggregation, 30g/m can be set to ²~ 120g/m ²left and right.Fiber number is 1dtex ~ 16dtex, is preferably 1dtex ~ 10dtex, is more preferably 1dtex ~ 5dtex.Filament can be non-crinkled fibre, but is preferably crinkled fibre.The degree of crispaturaing of crinkled fibre can be such as per inch 5 ~ 75, preferably 10 ~ 50, more preferably 15 ~ about 50.In addition, many uses crinkled fibre of evenly crispaturaing.

Preferred diffusion sheet 63 is arranged in the entirety of lower floor's breakthrough part 60, but, also can only arrange partly in a part for fore-and-aft direction or a part etc. for width.As long as diffusion sheet 63 is arranged on the bottom of lower floor's breakthrough part, except being arranged on except between top layer sheet 22 and opaque liquid sheet 21 as illustrated mode, the surface of top layer sheet 22 can also be sticked to.When arranging diffusion sheet 63, when top layer sheet and diffusion sheet 63 being fused directly or indirectly implementing the heating pressurization processing such as heat embossing processing above top layer sheet 22, the rigidity of the bottom of lower floor's breakthrough part uprises, and the path formed by lower floor's breakthrough part is difficult to collapse, because of but preferably.

(between hip the three-dimensional fold in portion)

In addition, in illustrated mode, the ledge 42 outstanding from the side of upper strata breakthrough part 50 extends along the longitudinal direction, and, the part of the front side and rear side that are positioned at this ledge 42 becomes the fixing non-rising portions 45 of the state of lodging respectively, part between these non-rising portions 45 becomes revocable rising portions 46, and, under the width both sides on surface are provided with the state stretched along the longitudinal direction in fold elastic flexible component 43, be fixed on the three-dimensional fold 40 in portion between the hip on this rising portions 46.Rising portions 46 be due to the effect of the contractility of fold elastic flexible component 43 as shown in double dot dash line in Fig. 4 from diaper surface rise part.

Also can not arrange the three-dimensional fold 40 in portion between hip, but due to upper strata breakthrough part 50 and lower floor's breakthrough part 60, between hip, the absorbtivity of portion C2 must decline, urine becomes easy movement, therefore, preferably arranges separately outside the three-dimensional fold 30 of sidepiece.

Between hip, the three-dimensional fold 40 in portion can be formed by installing special on diaper surface, but, preferably as illustrated mode, make top layer sheet 22 than upper strata breakthrough part 50 by the part of side curved go out and form ledge 42.

When arranging portion's solid fold 40 between hip, upper strata breakthrough part 50 expansion 52 in the longitudinal direction between hip the three-dimensional fold 40 in portion non-rising portions 45 between time (in other words, when the width position of the expansion 52 of upper strata breakthrough part 50 overlaps with the width position of the non-rising portions 45 of the three-dimensional fold 40 in portion between hip), between hip, the contractility of the fold elastic flexible component 43 of the three-dimensional fold 40 in portion acts on single layer structure part 23w effectively, the formation that above-mentioned boat-shaped caves in can be promoted, the shape maintains of depression is improved, because of but preferred.But the non-rising portions 45 of the three-dimensional fold 40 in portion also can be positioned at and lean on width center side or outside than the expansion 52 of upper strata breakthrough part 50 between hip.

Further, it is expected that between hip, the width position of the cardinal extremity of the ledge 42 of the three-dimensional fold 40 in portion is as illustrated mode, is separated from expansion 52 to side, but, also can be consistent with the lateral margin of expansion 52 or be positioned at expansion 52.Especially most preferably between hip, the width position of the cardinal extremity of the ledge 42 of the three-dimensional fold 40 in portion in the deployed state, is positioned at the outside of the expansion 52 of upper strata breakthrough part 50 and the two-layer structure upper of upper strata absorber 23A and lower floor absorber 23B.In addition, most preferably between hip, the width position of the end of the ledge 42 of the three-dimensional fold 40 in portion in the deployed state, is positioned at the position above by single layer structure part 23w.By being set to these configurations, single layer structure part 23w easily bends to the inside along the lateral margin of the expansion 52 as the upper strata breakthrough part 50 with two-layer structure portion boundary, and therefore, formation and the maintenance of the depression 72 of boat-shaped become better.

As the fold elastic flexible component 43 of the three-dimensional fold 40 in portion between hip material and fixing time percentage of elongation, can from the scope of the material identical with the three-dimensional fold 30 of sidepiece suitably choice for use.Even if form the three-dimensional fold 40 in portion between hip special of diaper surface installation and arrange top layer sheet in addition, even and if as illustrated mode make top layer sheet 22 than upper strata breakthrough part 50 by the part of side curved go out and form the three-dimensional fold 40 in portion between hip, region between at least for hip between the three-dimensional fold 40 in portion, when especially at least top layer sheet being set to water proofing property for surface indentation forming region, also can promote towards the diffusion of dorsal part, because of but preferred.

Between hip, the size in each portion of the three-dimensional fold 40 in portion can suitably determine, but, consider the standard adult using this disposable urine napkin, the fore-and-aft direction of preferred non-rising portions 45 is spaced apart about 150mm ~ 180mm, and the width of the cardinal extremity of preferred ledge 42 is spaced apart about 60mm ~ 80mm.In addition, the rising portions 36 of the three-dimensional fold 30 of preferred sidepiece is configured to the rising portions 46 of fold 40 more three-dimensional than portion between hip respectively to front and rear extension.

In illustrative example, during fabrication, consider the common manufacture of assembling along the fore-and-aft direction conveying material carrying out of disposable urine napkin, between hip the three-dimensional fold 40 in portion reach disposable urine napkin total length L (but, the fore-and-aft direction length of non-rising portions 45 is longer than the three-dimensional fold 30 of sidepiece), but the fore-and-aft direction scope that also can be set to the expansion 52 with upper strata breakthrough part 50 is benchmark and from the length near on front side of it near rear side.

(the 2nd mode of surface indentation forming region)

As shown in Figure 17 ~ Figure 19, substitute lower floor's breakthrough part 60 of the lower floor absorber 23B of the 1st mode and form lower floor's thinning part 64 that thickness is less than around (not through in a thickness direction), also can bring the advantage roughly the same with the 1st mode.Namely, in this 2nd mode, the intersection (the 1st is recessed to form portion) of the mid portion 51 of lower floor's thinning part 64 and upper strata breakthrough part 50 becomes the single layer structure of lower floor's thinning part 64, the position (the 2nd is recessed to form portion) of the expansion 52 of upper strata breakthrough part 50 becomes the single layer structure that the part 23w beyond by the thinning part of lower floor absorber 23B is formed, and the outside of the expansion 52 of upper strata breakthrough part 50 becomes the two-layer structure of upper strata absorber 23A and lower floor absorber 23B.Under wearing state, when disposable urine napkin to be sandwiched between two lower limbs in the width direction by compression, although power also acts on the single layer structure part 23w of the expansion 52 being positioned at upper strata breakthrough part 50 on approximating direction, but, this single layer structure part 23w easily bends to the inside along the lateral margin of the expansion 52 as the upper strata breakthrough part 50 with two-layer structure portion boundary, thus, this single layer structure part 23w bends to the inside relative to the two-layer structure part outside its width, part between this single layer structure part 23w is recessed into thereupon to the inside, the larger depression of width is formed on the surface of disposable urine napkin.And such depression is not only easily restored for the compression of width, and the single layer structure part 23w bent to the inside becomes wall and maintains the degree of depth of depression, therefore, and the maintenance of depression and even the maintenance excellence of surface gap.Therefore, in this 2nd mode, when urinating, in the urine of front side being excreted to this sunk area, not by absorbing in the part of surface movement with this larger surface gap for stream and flow to rear side, absorbed by the absorber 23 of rear side in this process.Therefore, it is possible to effectively prevent the less diffusion blocking caused of surface gap as existing issue.

The thickness of lower floor's thinning part 64 is not particularly limited, and can be set to about 10% ~ 50% of the thickness of the part beyond thinning part, under normal conditions, can be set to about 1mm ~ 5mm.Lower floor's thinning part does not limit by its formation method, and such as, except can by making surface density lower than except being formed around, the processing (can also heat as required) can also being undertaken compressing by through-thickness be formed.

In addition, comprise variation interior identical with the 1st mode, as long as the lower floor's breakthrough part 60 in the explanation of the 1st mode is replaced to lower floor's thinning part 64, thus omit further instruction.

(the 3rd mode of surface indentation forming region)

As shown in Figure 21 ~ Figure 22, make the lower in shape contrary of the upper strata breakthrough part of above-mentioned 1st mode and lower floor's breakthrough part, also can bring identical advantage.Label 80 in Figure 21 ~ Figure 22 represents upper strata breakthrough part, label 81 represents the width of upper strata breakthrough part 80, label 82 represents the fore-and-aft direction length of upper strata breakthrough part 80, label 90 represents lower floor's breakthrough part, label 91 represents the mid portion of lower floor's breakthrough part 90, label 92 represents the expansion of lower floor's breakthrough part 90, and label 95 represents the width of mid portion 91, and label 96 represents the width with the part of the expansion 92 of lower floor's breakthrough part 90.In this 3rd mode, upper strata breakthrough part 80 becomes with the intersection (the 1st is recessed to form portion) of the mid portion 91 of lower floor's breakthrough part 90 structure that there is not absorber 23, the position (the 2nd is recessed to form portion) of the expansion 92 of lower floor's breakthrough part 90 becomes the single layer structure of upper strata absorber 23A, and the outside of the expansion 92 of lower floor's breakthrough part 90 becomes the two-layer structure of lower floor absorber 23B and upper strata absorber 23A.Under wearing state, when disposable urine napkin to be sandwiched between two lower limbs in the width direction by compression, although power also acts on the single layer structure part 23w of the expansion 92 being positioned at lower floor's breakthrough part 90 on approximating direction, but, this single layer structure part 23w easily bends to the inside along the lateral margin of the expansion 92 as the lower floor's breakthrough part 90 with two-layer structure portion boundary, thus, this single layer structure part 23w bends to the inside relative to the two-layer structure part outside its width, part between this single layer structure part 23w is recessed into thereupon to the inside, the larger depression of width is formed on the surface of disposable urine napkin.And such depression is not only easily restored for the compression of width, and the single layer structure part 23w bent to the inside becomes wall and maintains the degree of depth of depression, therefore, and the maintenance of depression and even the maintenance excellence of surface gap.Therefore, in the utility model described in this, when urinating, in the urine of front side being excreted to this sunk area, not by absorbing the part of surface movement with this larger surface gap for stream and flow to rear side, absorbed by the absorber 23 of rear side in this process.Therefore, it is possible to effectively prevent the less diffusion blocking caused of surface gap as existing issue.

Although not diagram, also similarly can make the lower in shape contrary of the upper strata breakthrough part 50 of the 2nd mode and lower floor's thinning part 64.

In addition, variation is comprised interior identical with the 2nd mode with the 1st mode, as long as by the replacement up and down in the explanation of the 1st mode and the 2nd mode, thus omit further instruction.

(the 4th mode of surface indentation forming region)

In the 1st ~ 3rd mode, absorber is set to two-layer structure and forms surface indentation forming region, but, as shown in Figure 23 ~ Figure 26, in the absorber of single layer structure, by arranging surface indentation forming region of the present utility model, also can obtain the disposable urine napkin with same characteristic features.

More specifically, in the mode shown in Figure 23 ~ Figure 26, between the hip of the absorber 23 of single layer structure, the width central part of portion C2 is provided with surface indentation forming region 231, 232, this surface indentation forming region 231, 232 have the 1st of the elongate extended along the longitudinal direction is recessed to form portion 231 and is recessed to form the 2nd of the width both sides expansion of the fore-and-aft direction centre position in portion 231 or rearward position towards the 1st and be recessed to form portion 232, 2nd is recessed to form portion 232 becomes the thinning part that thickness is less than around (not through in a thickness direction), 1st is recessed to form the breakthrough part that portion 231 becomes through in a thickness direction.

In the disposable urine napkin with such absorber 23, under wearing state, become disposable urine napkin to be sandwiched between two lower limbs in the width direction by compress state time, surface indentation forming region 231,232 is out of shape in the mode that central authorities are forced out towards the outside of diaper successively in the width direction, further, depression 71,72 is formed on the surface of diaper.Now, in surface indentation forming region 231,232, compare and be only recessed to form by the 1st the part that portion 231 forms, be recessed to form by the 1st the width that portion 231 and the 2nd is recessed to form the part that portion 232 is formed and go out greatly the amount that the 2nd is recessed to form portion 232, thus form the larger depression 72 of width.And the female 72 that this width is larger guarantees rigidity to a certain degree because of thinning part, therefore, the maintenance of the shape of 72 and the maintenance of the degree of depth and even the surface gap of caving in is excellent.When urinating, in the urine in the region and front side thereof that are excreted to this depression 72, not by absorbing the part of surface movement with this larger surface gap for stream and flow to rear side, absorbed by the absorber 23 of rear side in this process.Therefore, it is possible to effectively prevent the less diffusion blocking caused of surface gap as existing issue.

As shown in Figure 27 and Figure 28, portion 231 can not be recessed to form the 1st and be set to breakthrough part and be set to thickness and be less than the thinning part that the 2nd is recessed to form portion 232.When the 1st is recessed to form portion 231 for breakthrough part, the diffusibility of urine is good, but, be recessed to form by the 1st path that portion 231 formed and be easily out of shape and likely collapse.Therefore, being set to thinning part by being recessed to form portion 231 by the 1st, making easily to maintain and be recessed to form by the 1st the path that portion 231 formed, promote that urine is recessed to form portion 231 by the 1st and spreads at fore-and-aft direction.

2nd thickness being recessed to form portion 232 is not particularly limited, and can be about 10% ~ 50% of the thickness of the part beyond surface indentation forming region 231,232, under normal conditions, can be about 1mm ~ 5mm.In addition, when being recessed to form portion 231 by the 1st and being set to thinning part, its thickness is not particularly limited, and can be the 2nd to be recessed to form about 10% ~ 50% of the thickness in portion 232, under normal conditions, can be about 1mm ~ 5mm.These thinning parts do not limit by its formation method, and such as, except can by making surface density lower than except being formed around, the processing (can also heat as required) can also being undertaken compressing by through-thickness be formed.

1st is recessed to form portion 231 can be set to the size shape identical with lower floor's breakthrough part 60 of the 1st mode.Namely, as long as the shape elongate that the 1st is recessed to form portion 231, except the rectangle that such as illustrated mode width is fixed in the longitudinal direction, can also suitably change, such as width changes the shape etc. of (such as, width expands along with towards rear side) in the longitudinal direction.1st size being recessed to form portion 231 can suitably determine, but consider the standard adult using this disposable urine napkin, preferred fore-and-aft direction length 231L is about 180mm ~ 210mm.In addition, the 1st width 231W being recessed to form portion 231 can suitably determine, but, less wide, better to the shape maintains of depression 72, therefore, under normal conditions, be preferably about 20mm ~ 40mm.Also can in the same manner as the lower floor's breakthrough part 60 shown in Figure 11 and Figure 12, spaced apartly in the direction of the width arrange the multiple 1st and be recessed to form portion 231.

Further, it is expected that, be arranged in the middle of the fore-and-aft direction of absorber 23 by being recessed to form portion 231 by the 1st, be namely set to the 1st and be recessed to form the configuration that portion 231 do not penetrate in the front and back of absorber 23, thus, the rigidity as absorber 23 entirety can be guaranteed.

2nd is recessed to form portion 232 can be set to the size shape identical with the part of the expansion 52 with upper strata breakthrough part 50 of the 1st mode.Namely, the width 232W in portion 232 is recessed to form about the 2nd, desirably, consider that the size (mainly the height of wall) of depression 72 or the shape maintains of depression 72 decide, desirably, 1st to be recessed to form the summation that the width 231W in portion 231 and the 2nd of its both sides be recessed to form the width 232W in portion 232 be the 1st 1.5 times ~ about 2 times of being recessed to form the width 231W in portion 231, more specifically, is about 36mm ~ 120mm.

The 2nd fore-and-aft direction position being recessed to form portion 232 can suitably determine, can as shown in the example of the figure, the 1st rearward position being recessed to form portion 231 be expanded to side, and fore-and-aft direction centre position also can be made to be formed to side expansion.In addition, although not diagram, but, also can be formed as, extend the 1st in the 2nd front side being recessed to form portion 232 and be recessed to form portion 231, and, to be recessed to form shape symmetrical before and after portion 232 with the 2nd of rearward position, add the 3rd in its width both sides and be recessed to form portion, under wearing state, the depression of a pair boat-shaped clips stria relatively (forming roughly hourglass-shaped depression) along its length.

The bending of the 2nd shape being recessed to form portion 232 can be lateral margin shape be diagramatic way also can be the curve-likes such as arc-shaped.In illustrated mode, become to be recessed to form the border in portion 231 for going to the bottom with the 1st, trailing edge and go to the bottom vertical trapezoidal (comprising the 2nd the 1st shape being recessed to form portion 231 being recessed to form portion 232 and centre thereof is pentagon), the 2nd part being recessed to form at least front side of the lateral margin in portion 232 is made to become shape along with being positioned at towards rear side outside width, but, trapezoidal (mid portion 51 shape comprising expansion 52 and centre thereof is hexagon) that also can be identical with the expansion 52 shown in Figure 10 (a).In addition, 2nd shape being recessed to form the lateral margin in portion 232 such as can in the same manner as the expansion 52 shown in (a) of Figure 13, become a part for front side along with the shape be positioned at stepwise towards rear side outside width, or in the same manner as the expansion 52 shown in (b) of Figure 13, become a part for front side along with the shape be positioned at towards front side outside width, 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, being recessed to form the position that portion 231 overlaps there is not absorber 23 with the 1st, therefore, although the diffusibility of urine is good, be recessed to form by the 1st path that portion 231 formed and be easily out of shape and likely collapse.Therefore, arrange in the 1st bottom being recessed to form portion 231 copying the 1st mode and promote that urine is when the diffusion sheet 63 of fore-and-aft direction diffusion, easy maintenance is recessed to form by the 1st the path that portion 231 formed, and promotes that urine is recessed to form portion 231 by the 1st and spreads at fore-and-aft direction.About material or the variation of diffusion sheet 63, due to identical with the 1st mode, thus omit the description.

When arranging portion's solid fold 40 between hip in the same manner as the 1st mode, the 2nd be recessed to form portion 232 in the longitudinal direction between hip the three-dimensional fold 40 in portion non-rising portions 45 between time (in other words, when the width position that the 2nd is recessed to form portion 232 overlaps with the width position of the non-rising portions 45 of the three-dimensional fold 40 in portion between hip), between hip, the contractility of the fold elastic flexible component 43 of the three-dimensional fold 40 in portion effectively acts on the 2nd and is recessed to form portion 232, the formation of above-mentioned depression can be promoted, the shape maintains of depression is improved, because of but preferably.But the non-rising portions 45 of the three-dimensional fold 40 in portion also can be positioned at and be recessed to form portion 232 by width center side or outside than the 2nd between hip.

Further, it is expected that the width position of the cardinal extremity of the ledge 42 of the three-dimensional fold 40 in portion is as illustrated mode between hip, is recessed to form portion 232 from the 2nd and is separated to side, but, also can be consistent with the lateral margin of expansion 52 or be positioned at expansion 52.In addition, most preferably between hip, the width position of the end of the ledge 42 of the three-dimensional fold 40 in portion in the deployed state, is in and is recessed to form position above portion 232 by the 2nd.By these configurations, the 2nd is recessed to form portion 232 easily bends to the inside along its lateral margin, and therefore, formation and the maintenance of depression 72 become better.Between other hip with the 1st mode, the three-dimensional fold 40 in portion is identical, thus omits the description.

(other)

In the 1st ~ 4th mode described above, absorber 23 is set to two-layer structure or single layer structure, but, also can be set to more than three layers.In addition, in scope of the present utility model, any one or more combination that surface indentation forming region 231,232 can be passed through in the stacked number of breakthrough part, thinning part (compression process, areal density), absorber 23 is formed.Therefore, such as, in the absorber 23 of multiple structure, breakthrough part is not set and the mode only arranging the thinning part of the 4th mode is also contained in this utility model.

As long as surface indentation forming region 231,232 is arranged within the scope of the fore-and-aft direction of portion C2 between hip, but, special desirably, 1st is recessed to form portion 231 extends to rear side from the front side of scrotum configuring area C1, the 2nd is recessed to form portion 232 rearward extends from the fore-and-aft direction middle position in scrotum configuring area C1 or its rear position.In addition, as illustrated mode, when preferably having the less constriction 23n of width in the middle of the fore-and-aft direction of absorber 23, the 1st is recessed to form portion 231 and the 2nd is recessed to form portion 232 and extends to the width of this constriction 23n along with within the scope of the fore-and-aft direction expanded towards rear or its rear.
