The shape of top flat 50 in 1st region R1 is different from the shape of top flat 50 in the 2nd region R2.More specifically, At least the shape of the 1st protrusion 511 is different with the shape of the 2nd protrusion 512.The variform structure of sheet material protrusion 51 refers to, piece The length of the width direction of material protrusion 51, the length of the front-rear direction L of sheet material protrusion 51, sheet material protrusion 51 height (thickness side To length), at least one in the shape (round rectangle etc.) of the vertical view of the pitch of sheet material protrusion 51 and sheet material protrusion 51 The different structure in part.In the top flat 50 of present embodiment, the height 511H of the 1st protrusion 511 and the height of the 2nd protrusion 512 512H is different, and the pitch P1 of the 1st protrusion 511 and the pitch P2 of the 2nd protrusion 512 are different.The shape of 1st protrusion 511 and the 2nd protrusion 512 shape is different, therefore, dresses the readily identified 1st region R1 of auxiliary.In addition, shape and the 2nd protrusion of the 1st protrusion 511 512 shape is different, and therefore, wearing auxiliary can hold the performance for being configured at the top flat of lower crotch region and be configured at rear waistline The difference of the performance of the top flat in region, can obtain urine and excrement can properly be absorbed such reassurance.

In addition, the shape of the 1st recess portion 521 and the shape of second recesses 522 can also be different.The shape of sheet concave 52 is not With structure refer to, it is the length of the width direction W of sheet concave 52, the length of the front-rear direction L of sheet concave 52, recessed in sheet material The different structure of shape, at least part of the position of opening 54 for the opening 54 that portion 52 is formed.

The top flat 50 of the 1st region R1 be formed with the 1st protrusion 511, the 1st recess portion 521, middle part 58, the 1st bottom 531 with And the 1st opening 541.Middle part 58 is set between the 1st adjacent protrusion 511.The height of middle part 58 is higher than the 1st protrusion 511 It spends low.Middle part 58 is prominent with respect to surface side T1 to skin relative to the 1st bottom 531.The top of middle part 58 is located at than the 1st protrusion Position of the non-skin with respect to surface side T2 is leaned at 511 top.The 1st bottom 531 is configured with around middle part 58.In being provided with Between portion 58 position at section (section shown in Fig. 4) in, it is convex by the 1st protrusion 511, the 1st recess portion the 521, the 1st in top flat 50 The sequence each section in portion 511 is disposed adjacently, in the 1st recess portion 521, by the 1st bottom the 531, the 1st the 541, the 1st bottom of opening 531, middle part 58, the 1st bottom the 531, the 1st be open the 541, the 1st bottom 531 sequence each section be disposed adjacently.In addition, can also To be not provided with middle part 58, the 1st protrusion 511 can be set also to substitute middle part 58.

The 2nd protrusion 512 and second recesses 522 are formed in the top flat 50 of the 2nd region R2.The 2nd region R2 top flat 50 not Form middle part.2nd protrusion 512 is configured to staggered.In the section (section shown in fig. 5) of the 2nd region R2, in top flat 50 In, it is disposed adjacently by sequence each section of the 2nd protrusion 512, second recesses 522, the 2nd protrusion 512, in second recesses 522, presses Sequence each section of 2nd bottom the 532, the 2nd the 542, the 2nd bottom 532 of opening is disposed adjacently.

Top flat 50 is provided with multiple sheet concaves 52 and sheet material protrusion 51, therefore, between top flat 50 and absorber 40 It is formed with space.By forming space between top flat 50 and absorber 40, can by the body fluid introduced using top flat 50 to this Space introduces, and can promptly absorb excreta using absorber, be able to suppress body fluid and remain on top flat.

In thus configured top flat 50, if excrement is discharged on the 1st region R1, excrement is incorporated in the 1st protrusion 511 Between the 1st recess portion 521.Excrement is clipped by the 1st protrusion 511, and is stayed in the 1st recess portion 521.Since excrement is incorporated in the 1st The contact area of recess portion 521, wearer and excrement tails off.Excrement is clipped by the wall of the 1st protrusion 511, therefore, is accommodated in for the time being In the case that excrement between 1st protrusion 511 touches skin, be able to suppress excrement between the 1st protrusion come out and it is attached again In wearer.Thus, it is possible to which the area for inhibiting excrement to be attached to skin increases.Among being arranged between the 1st protrusion 511 The excreta in space between the 58, the 1st protrusion 511 of portion is difficult to spread along front-rear direction L and width direction W.In addition, the 1st Protrusion 511 is configured to staggered, and the 1st recess portion 521 is truncated on front-rear direction L and width direction W.Thus, it is recessed to be accommodated in the 1st Excrement in portion 521 is difficult to spread along front-rear direction L and width direction W.Soft stool containing more moisture is via the 1st recess portion 521 the 1st opening 541 is shifted to absorber 40.

It in thus configured top flat 50, is discharged on the 2nd region R2 if urinating, urine is via the between the 2nd protrusion 512 2 recess portions 522 are spread along relative to rear direction L inclination and relative to the inclined inclined direction of width direction W.The mobility of urine It is higher, it is spread in the in-plane direction along the 2nd bottom 532, while via the 2nd opening 542 formed in the 2nd bottom 532 to suction Acceptor 40 shifts.In this way, urine is spread in the 2nd region R2, shift urine to absorber, and make in the 1st region R1 Soft stool and body fluid are shifted to absorber 40, while persistently keeping solid excrement, so as to inhibit body fluid, soft stool to wearer Skin attachment, wearing feeling improve.It can properly absorbent properties be different using the 1st region R1 and the 2nd region R2 of top flat Urine and excrement.

The height of top flat 50 in 1st region R1 (is from the length at the top of the 1st bottom 531 to the 1st protrusion 511, quite Height 511H in the 1st protrusion 511) R1H than the height of the top flat 50 in the 2nd region R2 (is from the 2nd bottom 532 to the 2nd protrusion The length at 512 top is equivalent to the height 512H of the 2nd protrusion 512) R2H high.Due to the height of the top flat 50 in the 1st region R1 Spend relatively high, in the 1st region R1, the skin and absorber 40 that can enable a wearer to are separated, and are absorbed the body that body 40 absorbs Liquid is difficult to return to skin side, is easy to the skin of wearer being maintained at dry state.

Height (length from the top of the 1st bottom 531 to the 1st protrusion 511) 511H of 1st protrusion 511 is than the 2nd protrusion 512 height (length from the top of the 2nd bottom 532 to the 2nd protrusion 512) 512H high.The excrement being discharged on the 1st region R1 The 1st recess portion 521 being incorporated between the 1st protrusion 511.At this point, the height 511H of the 1st protrusion 511 is higher than the 2nd protrusion 512 Therefore the wall of 1st protrusion 511 can be formed relatively high by degree 512H high.The wall for clipping excrement is higher, thus, it is easy to utilize 1st protrusion 511 keeps the excrement being accommodated in the 1st recess portion 521 for the time being.As a result, the skin in wearer is touched and is received When the surface for being contained in the excrement in the 1st recess portion 521, excrement can be persistently held in the 1st recess portion 521, prevent excrement from 1st recess portion 521 comes out and is again attached to wearer.

In addition, the height of the 1st protrusion 511 is relatively high, therefore, the gap between skin and absorber 40 is in the 1st region R1 In become larger.Aeration is got higher, and the air of diaper inside is able to suppress sultry to flowing out outside diaper.In addition, being accommodated in excrement Before between 1st protrusion 511, the thickness of top flat 50 is body pressure is applied to the 1st region R1 and state that the 1st protrusion 511 has been flattened And body pressure is not applied to the 1st region R1 and changes between state that the 1st protrusion 511 has erected.Due to the height of the 1st protrusion 511 Relatively high, the thickness difference of the top flat 50 as caused by the presence or absence of body pressure becomes larger, and air is easier to flow, and is easily obtained and inhibits sultry Effect.Furthermore it is possible to store many excrement between the 1st protrusion 511, excrement is easy to pass through in opening 54 because of self weight, can Increase the amount of the excrement guided via opening 54 to absorber 40.

On the other hand, the height 512H of the 2nd protrusion 512 is lower than the height 511H of the 1st protrusion 511, therefore, can be improved Skin sense of touch in 2 region R2.Lower crotch region 25 is contacted with the discharge port of wearer.Compared with rear waist region 30, in-leg Region 25 and the skin of wearer are closely sealed.Height 512H positioned at the 2nd protrusion 512 of the 2nd region R2 of lower crotch region 25 is obtained Inhibit, therefore, even can also make the 2nd convex in the case where lower crotch region that the 2nd region R2 is located at and skin are closely sealed Portion 512 is soft to the touching of skin.Skin sense of touch improves, and the wearing feeling of wearer improves.For such raising wearing feeling Viewpoint considers that the area of the 1st region R1 of area ratio of the 2nd region R2 is preferred greatly.Pass through the 2nd region R2 for being suitable for by skin sense of touch Area be arranged larger, can more improve wearing feeling.In addition, the height of the 2nd protrusion 512 is relatively low, and therefore, second recesses 522 storage space becomes smaller, and is able to suppress and is incorporated in the excrement of the 1st region R1 and flows to the 2nd region R2.

Pitch P2 long of the pitch P1 of 1st protrusion 511 than the 2nd protrusion 512.Space between 1st protrusion 511 becomes larger, energy It is enough that the storage space of excrement is formed larger.Thus, the excrement being discharged on top flat 50 is incorporated between the 1st protrusion 511, It is difficult to remain on the 1st protrusion 511.The case where being able to suppress the skin continuous contact of excrement and wearer, wearing feeling improve.Separately Outside, many excrement can be kept between the 1st protrusion 511, the self weight of excrement increases.For the top flat with fiber, by Increase in the self weight of excrement, the moisture for being included in excrement is easy to penetrate via interfibrous gap to absorber.Thus, make excrement Just the moisture in is promptly shifted to absorber, is able to suppress the feelings that the soft stool containing more moisture is persistently attached to skin Condition.In addition, smooth sense of touch can be presented in main the 2nd region for absorbing urine, main the 1st region for absorbing excrement can be presented can By ground absorbed as with thickness sense of touch.In 1 top flat of disposable diaper, pass through the different portion of setting sense of touch Point, wearer can discover the function soft to skin and the reliably function of absorption excrement.

In addition, the pitch of the 1st protrusion and non-constant, pitch ratio between the 1st protrusion of middle part configuration not across Pitch between 1st protrusion of middle part configuration is long.The pitch of longest 1st protrusion is configured to the section than longest 2nd protrusion Distance.

511 height of sheet material protrusion be 0.3mm or more and 10.0mm hereinafter, more preferably 0.4mm or more and 6.0mm hereinafter, It is further preferred that 0.5mm or more and 4.5mm or less.The pitch of sheet material protrusion 51 is 0.3mm or more and 10.0mm hereinafter, more excellent Choosing is 0.5mm or more and 5.0mm hereinafter, being further preferred that 1.0mm or more and 4.5mm or less.Sheet material formed according to this Protrusion 51 inhibits by the incongruity of the excessively obvious caused appearance in sheet material protrusion 51, and wearing auxiliary is easily obtained reassurance. In addition, can visual identification sheet material protrusion 51, therefore, wearing auxiliary be easily obtained by 51 bring of sheet material protrusion for absorb The reassurance of performance.

The size of opening is 1.0mm or more and 8.0mm hereinafter, more preferably 1.5mm or more and 5.0mm or less.Opening is got over Greatly, the permeability of excrement is better, on the other hand, a possibility that return there is also the excrement after absorption from aperture portion, it is therefore preferable that It is set as the interval close to the sheet material protrusion and the size of width according to the interval of sheet material protrusion and width (difference is 2mm or less).It is logical The opening for crossing the size at the interval and width that are positioned proximate to the sheet material protrusion, in terms of visual image and function can be taken into account.

Front-end edge of the second recesses 522 from the front-end edge R1F of the 1st region R1 to top flat 50 continuously configures.Second recesses 522 Continuously, therefore, front-end edge of the body fluid from the front-end edge R1F of the 1st region R1 to top flat 50 can be made successfully to spread, can with compared with Big area shifts urine to absorber 40.

In the boundary of the 1st region R1 and the 2nd region R2, the 1st recess portion 521 and second recesses 522 phase on front-rear direction L Even.Space in 1st recess portion 521 is connected to the space in second recesses 522, therefore, excreta can be made in the 1st region R1 and It is successfully spread between 2nd region R2.Even for example, the wearing position of absorbent commodity deviates, excrement is discharged to the 2nd In the case where the R2 of region, the excrement can also be guided to the 1st region R1, excrement is stored and absorbed using the 1st region R1.

In the 1st region R1, the standing angle [alpha] (referring to Fig. 4) in the 1st convex wall portion 591 compares the standing angle in the 2nd convex wall portion 592 It is big to spend β (referring to Fig. 5).The standing angle [alpha] in the 1st convex wall portion 591 is bigger than the standing angle beta in the 2nd convex wall portion 592, the 1st convex wall portion 591 become steeper inclination.Therefore, it is readily able to keep the excretion being incorporated in the 1st recess portion 521 using the 1st protrusion 511 Object inhibits the excreta stored for the time being to deviate from from the 1st recess portion 521.

The standing angle [alpha] in the 2nd convex wall portion 592 is smaller than the standing angle beta in the 1st convex wall portion 591, the 2nd convex wall portion 592 become than More gentle inclination.2nd region R2 is at least configured at lower crotch region 25.Compared with rear waist region 30, lower crotch region 25 with The skin of wearer is closely sealed.Since the convex wall portion of the 2nd region R2 is gentle inclination, even be located in the 2nd region R2 In the case that lower crotch region and skin are closely sealed, also the 2nd protrusion 512 can be made soft to the touching of skin.

In addition, the angle of the standing in convex wall portion 59 can measure by the following method.Using cold spraying etc., from absorbability object Product take out the sheet material of measure object, cut off the protrusion and its periphery of measurement site in parallel with width direction.Cutting is to utilize cutting edge of a knife or a sword The mode that the cutter (such as new blade of cutter) of benefit as far as possible flattens protrusion carries out.It is generated with sheet material not after severance In the state that top flat is placed in horizontal plane by the mode of fold, section is amplified to 20 times using microscope, pair cross-section is clapped It takes the photograph.For captured section, to skin opposite face side surface (surface other than the fiber the to have fluffed) phase in convex wall portion The standing angle of horizontal plane is measured.

Fiber and the 2nd convex wall compared with the fiber being orientated along front-rear direction and width direction, in the 1st convex wall portion 591 The fiber that there is fiber in portion 592 the more thickness direction along top flat to be orientated.According to such absorbent commodity, it is easy to Maintain the non-skin of sheet material protrusion 51 with respect to the space of surface side, sheet material protrusion 51 is soft to the touching of skin, and wearer can obtain Obtain soft sense of touch.In addition, being easy to using the fiber being orientated along thickness direction T along thickness direction T lead body fluids.Thus, Even, also can be by the body fluid in convex wall portion 59 promptly to suction in the case where the height of sheet material protrusion 51 is configured to higher situation The guidance of acceptor side.

In addition, the fiber orientation of protrusion wall is orientated along thickness direction and refers to, it is being formed with sheet material protrusion and sheet concave In the state of, fiber spends~-45+45 relative to thickness direction (from the skin surface side of sheet material towards the direction of non-skin surface side) It is orientated in the range of degree.In addition, fiber orientation measurement using Co., Ltd.'s Keyemce digital microscope VHX-100 into Row, has carried out the measurement of fiber orientation with following measuring method.(1) sample is pacified in a manner of it can observe convex wall portion surface It is placed on observation platform；(2) by the focuses of lens alignment sample other than the fiber irregularly to fly out to front most with Preceding fiber；(3) 3D rendering of sample is generated on a pc screen.Then, 3D rendering is converted into 2D image by (4)；(5) in screen On mark the parallel lines that a plurality of thickness direction to measurement range convex wall portion carries out appropriate equal part.(6) marking parallel lines and In each unit segmented out, the number of fiber towards all directions is measured, then, (7) are for the whole in setting range Number of fiber, ratio to the number of fiber of the fiber orientation towards thickness direction and towards the direction orthogonal with thickness direction The ratio of the number of fiber of fiber orientation is calculated, and calculates the fiber orientation so as to measure.

The bending stiffness of 1st region R1 is higher than the bending stiffness of the 2nd region R2.Technology strain formula meeting is added in bending stiffness use Society KES FB-2 is measured.Preparing size becomes the test film of 50mm × 100mm, and one end of the length direction of test film is pressed from both sides A chuck being held in a pair of of chuck, is held on another chuck for the other end of the length direction of test film.One chuck It is rotated centered on another chuck, is measured as a result, with bending stiffness of the torque detector to test film after bending.It is quasi- Standby 5 groups of test films, and the average value of measured value is set as bending stiffness.
