But, the invention is not limited in this.

Veutro band member 20 includes soft sheet material and multiple elastic component 23 (example of two rectangles As, elastic threads), the soft sheet material of said two rectangle is two adhesive-bonded fabrics 21,22 at this. As shown in Figure 4, two adhesive-bonded fabrics 21,22 and the elastic component planted between which 23 overlap and combine, and multiple elastic component 23 is arranged in a longitudinal direction accordingly Elastic component between Existential Space, and the plurality of elastic component along horizontal direction to prolong The state of stretching is fixed to adhesive-bonded fabric 21,22.And in DLZ component 30, two nonwovens Fabric 31,32 is overlapping with the elastic component 33 planted between which and combines, and many Individual elastic component 33 (such as, elastic threads) is arranged in a longitudinal direction at corresponding elastic structure Existential Space between part, and the plurality of elastic component is solid with extension state along horizontal direction Surely adhesive-bonded fabric 31,32 is arrived.Therefore, veutro band member 20 and DLZ component 30 are imparted Extensibility in a lateral direction, thus diaper 1 is configured to adaptive wearer.In order to enter Row explanation below, is arranged in veutro band member 20 and stretches along horizontal direction or shrink Elastic component 23 be referred to as veutro elastic component 23, and be arranged in DLZ component 30 and The elastic component 33 stretched along horizontal direction or shrink is referred to as dorsal part elastic component 33.Need It is noted that veutro band member 20 (the veutro elasticity that Fig. 2 and Fig. 3 is in extension state Component 23) and the plane graph of DLZ component 30 (dorsal part elastic component 33).

Then, along horizontal direction arrange veutro band member 20 from absorb main body 10 non-skin Skin side covers in a longitudinal direction the end sections 10ea absorbing main body 10, described suction Receive main body to arrange in a longitudinal direction, and the central part that veutro band member 20 is in a lateral direction Divide and be fixed to one end sections 10ea.On the other hand, the back of the body arranged along horizontal direction Side band member 30 from absorb main body 10 non-skin side cover absorb main body 10 along longitudinal side To the other end part 10eb, described absorption main body is arranged in a longitudinal direction, and dorsal part The middle body along horizontal direction of band member 30 is fixed to described the other end part 10eb. It should be noted that absorb main body 10 be arranged to make its not with the end portion of veutro band member 20 Divide the end sections 30E of 20E and DLZ component 30 the most overlapping, described end sections 20E, 30E is positioned on waist side in a longitudinal direction.Additionally, absorb main body 10 and veutro band member 20 Each portion in the part that overlapping part and absorption main body 10 and DLZ component 30 overlap Binding agent etc. completely or partially (in neighboring, central part office etc.) point is utilized to combine.

Additionally, veutro band member 20 and DLZ component 30 each all include: bound fraction 40, In described bound fraction, two lateral edges 20e along horizontal direction of veutro band member 20 A part and a part of two lateral edges 30e along horizontal direction for DLZ component 30 In conjunction with；With non-binding part 41, described non-bonded portion split-phase for bound fraction 40 along vertical Crotch side (center side) it is positioned to direction, and in described non-binding part, veutro band structure Two lateral edges 20e of part 20 and two lateral edges 30e of DLZ component 30 are not bound with. It should be noted that in this embodiment, veutro band member 20 and DLZ component 30 exist The state of each end edge E alignment being positioned in a longitudinal direction on waist side combines.So And, the invention is not limited in this, veutro band member 20 and DLZ component 30 along vertical Each end edge E being positioned on waist side to direction all can the most in a longitudinal direction Skew.Additionally, in order to carry out explanation below, veutro band member 20 in a longitudinal direction with The overlapping part of bound fraction 40 is referred to as veutro main body 20A, and veutro band member 20 along Longitudinal direction is referred to as veutro extension 20B with the overlapping part of non-binding part 41.Similarly, The part overlapped with bound fraction 40 in a longitudinal direction of DLZ component 30 is referred to as dorsal part master Body 30A, and the portion overlapped with non-binding part 41 in a longitudinal direction of DLZ component 30 Divide and be referred to as dorsal part extension 30B.

It should be noted that as veutro band member 20 and the associated methods of DLZ component 30, Well-known associated methods can be used, such as, use binding agent, restraint zone, adhesive tape, heat Envelope, high frequency seal and the associated methods of ultrasonic sealing.Furthermore, it is possible to veutro band member 20 With DLZ component 30 combine state, i.e. provide a user with diaper with pants type form, and also Can be not bound with veutro band member 20 and DLZ component 30 but treat to be combined by user State, i.e. provide a user with diaper with open mode.

===veutro extension 20B and dorsal part extension 30B===

Fig. 5 is to explain veutro elastic component 23 He being arranged in the 20B of veutro extension The diagram of the dorsal part elastic component 33 being arranged in the 30B of dorsal part extension.Should be noted that It is that Fig. 5 shows the diagram of pants-type diaper 1, in described pants-type diaper, veutro band structure Part 20 and DLZ component 30 combine at bound fraction 40, i.e. veutro band member 20 He The state that DLZ component 30 overlaps and extends.Fig. 6 show in the raw in abdomen Extension, side 20B and the diagram of dorsal part extension 30B.One is carried, on diaper 1 along band Urine drains position be positioned at abdomen relative to the middle body CL in a longitudinal direction of diaper 1 On side.Therefore, such design is incorporated in diaper 1 so that absorbing main body 10 midfield The partially absorbable amount of liquid in side is more than the absorbable amount of liquid of posterior components.Such as, in this reality Execute in the diaper 1 of example, as in figure 2 it is shown, absorbent core 11 relative to diaper 1 along longitudinal direction The middle body CL in direction shrinks maximum in the position on dorsal part.So, main body 10 is absorbed Urine can be absorbed in time and definitely.

Because that in diaper 1, define contraction, so need front and rear Correctly dress diaper.To this end, as it is shown on figure 3, such as, diaper 1 has for distinguishing urine The word of the front and rear of cloth 1 and diagram, described word and diagram are printed on back-sheet 13 Part 13f overlapping with veutro band member 20 on and back-sheet 13 with DLZ structure In overlapping part 13b of part 30.But, in the case of three-member type diaper 1, if veutro The shape of band member 20 is identical with the shape of DLZ component 30, then there is a risk that, That is, user can not identify the difference between the front and rear of diaper 1, and is not checking It is printed on diaper 1 in the case of the word on diaper 1 etc. may be worn as mistakenly (or using Family may be worn as) front and rear overturn.

Then, in the diaper 1 of the present embodiment, veutro elastic component 23 and dorsal part elastic component 33 be by extension state relative to bound fraction 40 in a longitudinal direction on crotch side Offset relative to each other in a longitudinal direction and arrange, as shown in Figure 5.In other words, veutro The position of the veutro elastic component 23 of extension 20B and the dorsal part of dorsal part extension 30B The position of elastic component 23 is the most different, and diaper 1 is constructed such that veutro The veutro elastic component 23 of extension 20B and the dorsal part elasticity structure of dorsal part extension 30B Part 33 is the most overlapping along the thickness direction of diaper 1.

By this way, it is applied to veutro extension due to the contraction of veutro elastic component 23 Affecting and being applied to dorsal part extension due to the contraction of dorsal part elastic component 33 on 20B The impact of 30B is different, and veutro extension 20B and dorsal part extension 30B can be individually Deformation, therefore (that is, at veutro elastic component 23 and dorsal part bullet in the naturalness of diaper 1 In the state of property members contract), the shape of veutro extension 20B and dorsal part extension 30B Shape difference.More specifically, as shown in Figure 6, it is possible to distinguish veutro extension The waveform of 20B lateral edges 20Be in a lateral direction and dorsal part extension 30B are laterally The waveform of the lateral edges 30B on direction, and can distinguish veutro extension 20B along Longitudinal direction is positioned at waveform and the dorsal part extension 30B of end edge 20Be on crotch side The waveform of end edge 30Be being positioned in a longitudinal direction on crotch side.By this way, The front and rear of diaper 1 is defined by veutro extension 20B and dorsal part extension 30B Between difference, and by allowing user to identify the difference between the front and rear of diaper 1 Different diaper 1 is prevented to be worn as mistakenly putting the cart before the horse.

Veutro elastic component 23 and dorsal part elasticity structure can be determined by method shown below Part 33 is phase the most in a longitudinal direction in crotch in a longitudinal direction relative to bound fraction 40 For being offset from one another.It should be noted that and not only determine abdomen in all methods to be shown below The urine that side elastic component 23 and dorsal part elastic component 33 offset relative to each other in a longitudinal direction Cloth obtains the effect above, and determines veutro elasticity structure in either method described below The diaper that part 23 and dorsal part elastic component 33 offset relative to each other in a longitudinal direction also can Obtain the effect above, and these diapers are equivalent to the diaper 1 (absorbent article) according to the present invention. Additionally, the method being shown below is one of example, thus can be by the method except being shown below Outside other method determine that veutro elastic component 23 is the most relative with dorsal part elastic component 33 It is offset from one another.

First, giving this method, described method confirms intuitively: at veutro band member 20 In the state combined at bound fraction 40 with DLZ component 30 and at veutro band member 20 With DLZ component 30 extend state in, from being positioned in a longitudinal direction of bound fraction 40 End edge 40a on crotch side starts the n-th position being positioned in a longitudinal direction on crotch side Put (N=1,2,3 ...) place veutro elastic component 23 and from bound fraction 40 along vertical The same end edge 40a being positioned on crotch side to direction starts to be positioned in a longitudinal direction crotch The dorsal part elastic component 33 of the n-th position on side is the most in a longitudinal direction relative to that This skew.Additionally, this method is not limited to this confirmation method directly perceived.Such as, distance (figure La1 in 5) with distance (Lb1 in Fig. 5) compared with, and if above-mentioned distance the most not With, then can also determine veutro elastic component 23 and dorsal part elastic component 33 in a longitudinal direction Offsetting relative to each other, described distance La1 is the position in a longitudinal direction from bound fraction 40 The N being positioned in a longitudinal direction on crotch side that end edge 40a on crotch side starts Veutro elastic component 23 to the DLZ component 30 at individual position (such as, the 3rd position) place In a longitudinal direction between end edge 30BE on crotch side in a longitudinal direction away from From, described distance Lb1 is being positioned in a longitudinal direction crotch side from bound fraction 40 The n-th position being positioned in a longitudinal direction on crotch side that end edge 40a starts is (such as, 3rd position) position in a longitudinal direction of dorsal part elastic component 33 to DLZ component 30 at place Distance in a longitudinal direction between end edge 30BE on crotch side.Additionally, not only Only can measure the end edge being positioned in a longitudinal direction crotch side from DLZ component 30 Edge 30BE is to the distance of elastic component 23,33, but also can such as measure from veutro band structure End edge 20BE being positioned in a longitudinal direction on crotch side of part 20 or from bound fraction End edge 40a being positioned in a longitudinal direction on crotch side of 40 or from DLZ component 20 End edge E being positioned in a longitudinal direction on waist side or from the edge of veutro band member 30 Longitudinal direction end edge E on waist side to the distance between elastic component 23,33.

It addition, in the deployed condition shown in Fig. 2 and Fig. 3, tear the bound fraction of diaper 1 40, and in the state that veutro band member 20 and DLZ component 30 extend, distance (figure La2 in 5) with distance (Lb2 in Fig. 5) compared with, and if above-mentioned distance the most not With, then can also judge veutro elastic component 23 and dorsal part elastic component 33 in a longitudinal direction Offsetting relative to each other, described distance La2 is the position in a longitudinal direction from bound fraction 40 The N being positioned in a longitudinal direction on crotch side that end edge 40a on crotch side starts Veutro elastic component 23 to the veutro band member 20 at individual position (such as, primary importance) place Distance in a longitudinal direction between end edge E in waist side in a longitudinal direction, Described distance Lb2 is the end being positioned in a longitudinal direction crotch side from bound fraction 40 The n-th position (such as, that what edge 40a started be positioned on crotch side in a longitudinal direction One position) being positioned in a longitudinal direction of dorsal part elastic component 33 to DLZ component 30 at place Distance in a longitudinal direction between end edge E in waist side.It should be noted that also Can such as measure the end being positioned in a longitudinal direction crotch side from veutro band member 20 Edge 20BE or from the end edge being positioned in a longitudinal direction crotch side of bound fraction 40 Edge 40a is to the distance of elastic component 23,33.But, in this case, end edge The position of 20BE, 40a was preferably marked at veutro band member 20 and the back of the body before launching diaper 1 On side band member 30.

Additionally, when implementing said method, such as, veutro band member 20 and DLZ component 30 are preferably in the state being fastened to be respectively provided with the component of tiny irregular portion in its surface, To keep veutro band member 20 and the extension state of DLZ component 30.Additionally, said method Implement the most in such a situation, described state i.e. abdomen before arranging elastic component 23,33 Side band member 20 and DLZ component 30 extend up to veutro band member 20 and DLZ component The length along horizontal direction of 30 becomes or close to constituting veutro band member 20 and DLZ Till the length along horizontal direction of the adhesive-bonded fabric of component 30.

Additionally, in the diaper 1 of the present embodiment, the veutro elastic component 23 of veutro main body 20A With the dorsal part elastic component 33 of dorsal part main body 30A in extension state the most relative In being offset from one another.Accordingly, because the veutro elastic component 23 being positioned in veutro main body 20A Shrink and the impact that is applied on the 20B of veutro extension with owing to being positioned in dorsal part main body 30A The contraction of dorsal part elastic component 33 and the impact that is applied on the 30B of dorsal part extension is different, It is possible to the shape of difference veutro extension 20B is with dorsal part extension 30B's further Shape.Therefore, it is possible to prevent diaper 1 to be worn as mistakenly putting the cart before the horse definitely.But, The invention is not limited in this, and the veutro elastic component 23 of veutro main body 20A and dorsal part The dorsal part elastic component 33 of main body 30A can also alignment in a longitudinal direction.

Additionally, in the diaper 1 of the present embodiment, as shown in Figures 3 and 5, constitute DLZ structure The adhesive-bonded fabric 31,32 of part 30 length L30 in a longitudinal direction is than constituting veutro band member The adhesive-bonded fabric 21,22 of 20 length L20 length in a longitudinal direction.It addition, veutro band structure End edge E being positioned in a longitudinal direction on waist side of part 20 and DLZ component 30 is each other Alignment.Therefore, the position in a longitudinal direction of veutro band member 20 (veutro extension 20B) End edge 20BE on crotch side and DLZ component 30 (dorsal part extension 30B) End edge 30BE being positioned in a longitudinal direction on crotch side in a longitudinal direction relative to It is offset from one another.Therefore, it is possible to the shape further discriminating between veutro extension 20B is prolonged with dorsal part Extending portion divides the shape of 30B, and prevents diaper 1 to be worn as mistakenly front and back running with can determine Fall.

Especially, by making being positioned in a longitudinal direction on crotch side of DLZ component 30 End edge 30BE being positioned in a longitudinal direction on crotch side relative to veutro band member 20 End edge 20BE is in a longitudinal direction towards crotch's side skew, and the shape of diaper 1 can connect The shape of nearly general underpants.Therefore, it is possible to prevent diaper 1 from dressing mistakenly with further determining that One-tenth is put the cart before the horse.Even if additionally, user not can confirm that the word etc. being printed on diaper 1, It is prone to distinguish the front and rear of diaper 1.Therefore, it is possible to dress diaper 1 rapidly, and Word etc. can be eliminated from diaper 1.It addition, because of veutro band member 20 in a longitudinal direction End edge 20BE being positioned on crotch side is arranged closer to waist side (upside), so expanding Leg-openings 1HL, and therefore when dressing, veutro band member 20 is not easy to wale wearing The lower limb of person.Thus, it is easy to dress diaper 1, and leg movable of wearer can be expanded Scope.Meanwhile, because the end being positioned in a longitudinal direction on crotch side of DLZ component 30 Edge 30BE arranges closer to crotch side (downside), it is possible to strengthen the buttocks to wearer The covering performance in portion.But, the invention is not limited in this, than the edge of DLZ component 30 End edge 30BE that longitudinal direction is positioned on crotch side, veutro band member 20 along vertical Being positioned at end edge 20BE on crotch side to direction can be in a longitudinal direction towards crotch side Skew further.

Additionally, in the diaper 1 of the present embodiment, as it is shown in figure 5, connect most The dorsal part elastic component 33e of nearly crotch side is arranged in order to relative to the most closest The veutro elastic component 23e of crotch side is in a longitudinal direction towards crotch's side skew.With this side Formula, by by a longitudinal direction closest to the veutro elastic component 23e of crotch side closer to waist Side (upside) is arranged, veutro elastic component 23 is not easy to wale the leg of wearer when dressing, Diaper 1 is prone to dress, and can expand the movable range of wearer leg.On the other hand, By by a longitudinal direction closest to the dorsal part elastic component 33e of crotch side closer to crotch side (downside) is arranged, dorsal part extension 30B can be assemblied in closer to wearer crotch side Position.Therefore, wherein dorsal part extension 30B is prone to the region rolled up, i.e. relative to Dorsal part elastic component 33e near crotch side is in the region on crotch side in a longitudinal direction Can constriction, thus enhance the covering performance of the buttocks to wearer.But, the present invention is also Being not limited to this, the veutro elastic component 23e near crotch side can be with cloth in a longitudinal direction It is set to relative in a longitudinal direction near the dorsal part elastic component 33e of crotch side along longitudinal direction Direction is closer to crotch side.

Additionally, in the present embodiment, overlap at veutro band member 20 and DLZ component 30 In region, veutro elastic component 23 and dorsal part elastic component 33 are alternately arranged in a longitudinal direction. But, the invention is not limited in this.Such as, relative to bound fraction 40 along longitudinal side To crotch side in, multiple dorsal part elastic components 33 can be relative to multiple veutro elastic components The region collective in a longitudinal direction of 23 collective's layouts is arranged closer at crotch side.This Outward, as it has been described above, in view of convenience, the mobility of leg and the covering performance of buttocks dressed, Preferably determine veutro elastic component 23 and the arrangement of dorsal part elastic component 33 and veutro Band member 20 length in a longitudinal direction and DLZ component 30 length in a longitudinal direction, Veutro elastic component 23e near crotch side in a longitudinal direction is made to be arranged in groin Place, and dorsal part elastic component 33e near crotch side is arranged in leg in a longitudinal direction And the intersection between buttocks.

Additionally, as shown in Figures 2 and 4, the lower limb stretching in a longitudinal direction or shrinking encloses elastic structure Part 15 is arranged on two sidepieces along horizontal direction absorbing main body 10, dorsal part extension Part and the absorption being in extension state arranged by the elastic component 33 of dorsal part wherein dividing 30B The lower limb wherein of main body 10 encloses elastic component 15 and arranges that the part being in extension state is combined. Therefore, dorsal part elastic component 33 in the 30B of dorsal part extension with extension state arrange Part and lower limb enclose the part with extension state layout of elastic component 15 and intersect and pass through Adhesive-bonded fabric 31 and outer sheet 14 combine, and described adhesive-bonded fabric constitutes DLZ component 30. Therefore, as it is shown in figure 5, when dress diaper 1 time, be applied with dorsal part elastic component 33 for The pulling force Fa of dorsal part extension 30B and lower limb is pulled to enclose elastic component 15 along horizontal direction For pulling the pulling force Fb of dorsal part extension 30B in a longitudinal direction.In other words, pull Power Fab of dorsal part extension 30B is made along the direction that horizontal direction and longitudinal direction are combined With.Therefore, the Adapter Property of dorsal part extension 30B is enhanced such that it is able to strengthen buttocks The covering performance in portion, described dorsal part extension imparts between the front and rear of diaper 1 The part of difference.

It should be noted that the dorsal part elastic component 33 being positioned in DLZ component 30 is arranged to Not its gamut is in extension state, the part (such as, two of dorsal part elastic component 33 Individual end) do not arrange that (fixing) is in extension state, and therefore this part does not have Help the extensibility of DLZ component 30.Similarly, veutro elastic component 23 and lower limb enclose bullet Property component 15 also includes the part not being arranged in extension state.At Fig. 2, Fig. 3 and In Fig. 5, illustrate only veutro elastic component 23, dorsal part elastic component 33 and lower limb and enclose elasticity The part being arranged in extension state of component 15.

Additionally, also in veutro and dorsal part, the veutro bullet wherein of veutro extension 20B Property component 23 be arranged in extension state part and absorb main body 10 lower limb wherein enclose bullet The part that property component 15 is arranged in extension state is combined.Therefore, veutro elastic component Part and the lower limb arranged with extension state in the 20B of veutro extension of 23 enclose elastic component The part that the layout of 15 is in extension state intersects and by adhesive-bonded fabric 21 with outer Portion's sheet material 14 combines, and described adhesive-bonded fabric constitutes veutro band member 20.Therefore, urine is being dressed During cloth 1, the power pulling veutro extension 20B is combined along horizontal direction and longitudinal direction Direction effect.Therefore, even if after veutro absorption main body 10 absorbs urine, it is also possible to press down System is sagging and produce space because only absorbing main body 10 between wearer and diaper 1, thus presses down There is leakage of exudates in system.

But, wherein dorsal part elastic component 33 in the 30B of dorsal part extension to extend shape The part of state layout and lower limb enclose the part with extension state layout of elastic component 15 and intersect And in conjunction with region length (Lc in Fig. 5) in a longitudinal direction more elastic than wherein veutro Part and the lower limb arranged with extension state in the 20B of veutro extension of component 23 enclose elasticity The part arranged with extension state of component 15 intersects and the region that combines is longitudinal side Length (Ld in Fig. 5) upwards is longer.More specifically, veutro extension 20B To enclose the quantity of the veutro elastic component 23 that elastic component 15 intersects with lower limb be three, and dorsal part Extension 30B encloses the quantity of the dorsal part elastic component 33 that elastic component 15 intersects with lower limb and is Six.This can also understand according to such reason, described reason i.e.: than veutro band member End edge 20BE being positioned in a longitudinal direction on crotch side of 20, DLZ component 30 It is positioned at end edge 30BE on crotch side in a longitudinal direction in a longitudinal direction closer to hip Side, portion offsets.Therefore, the Adapter Property of dorsal part extension 30B can be enhanced to higher than abdomen The Adapter Property of extension, side 20B, and the covering performance to buttocks can be further enhanced. But, the invention is not limited in this.Such as, veutro elastic component 23 and dorsal part elastic component 33 lower limbs can being not joined to so that extension state is arranged enclose elastic component 15, and wherein veutro prolongs Extending portion divides the veutro elastic component 23 of 20B and lower limb to enclose the cross one another region of elastic component 15 and exist It is elastic that length on longitudinal direction can also be made for the dorsal part than wherein dorsal part extension 30B It is longer that component 33 and lower limb enclose the cross one another region of elastic component 15 length in a longitudinal direction.

Additionally, the mankind are generally mobile towards veutro (front side) by its lower limb, and therefore absorb master Body 10 is generally pulled towards veutro.Therefore, with at dorsal part, absorption main body 10 is pulled to horizontal stroke Pulling force to the outside in direction is compared, and absorption main body is pulled to the pulling force of veutro in a longitudinal direction Easily become more to occupy an leading position, and thus absorb main body 10 and offset, and the row of being susceptible to Let out thing leakage.But, in the diaper 1 of the present embodiment, enclose with the lower limb arranged with extension state Elastic component 15 intersects and is attached to described lower limb and encloses the dorsal part elastic component 33 of elastic component Quantity (being ten in Figure 5) ratio encloses elastic component 15 with the lower limb arranged with extension state and intersects And the quantity being attached to the veutro elastic component 23 that described lower limb encloses elastic component (is in Figure 5 Seven) many.Therefore, even if absorbing main body 10 because of the motion of the lower limb of wearer by along longitudinal side To being pulled to veutro, pull the power absorbing main body 10 also big in dorsal part along horizontal direction, thus Absorption main body 10 is prevented to offset and inhibit leakage of exudates.

Additionally, as it is shown on figure 3, not having and absorption in a longitudinal direction at veutro band member 20 In the overlapping part of main body 10, veutro elastic component 23 is continuously arranged in abdomen along horizontal direction Between two end sections along horizontal direction of side band member 20.On the other hand, at veutro In the part overlapped with absorption main body 10 in a longitudinal direction of band member 20, veutro elasticity structure Part 23 along horizontal direction discontinuous be arranged in veutro band member 20 along horizontal direction Between two end sections.Specifically, two not overlapped with absorption main body 10 laterally In each of end regions 20C, veutro elastic component 23 is arranged continuously along horizontal direction, But, in the middle section 20D overlapping with absorbing main body 10, veutro elastic component 23 edge The discontinuous layout of horizontal direction.In this embodiment, the edge of only middle section 20D Two end sections horizontal direction are provided with veutro elastic component 23, and veutro elasticity structure Part 23 is along the discontinuous layout of horizontal direction.Even if it addition, being arranged in middle section continuously The veutro arranged between two end sections along horizontal direction of 20D and with extension state Elastic component 23 is cut in the case of a part or some, veutro elastic component 23 along the most discontinuous layout of horizontal direction.

By this way, being arranged in and absorbing main body 10 overlapping district in veutro band member 20 Veutro elastic component 23 in territory, along the discontinuous layout of horizontal direction, is inhaled therefore, it is possible to stop Receive main body 10 to shrink because of veutro elastic component 23, suppress to occur fold in absorbing main body 10 And it is open and flat to keep absorbing main body 10.This prevent be printed on back-sheet with veutro band member Word etc. in 20 overlapping parts 13f is difficult to be seen, and prevents diaper 1 mistakenly It is worn as putting the cart before the horse.Additionally, because the absorption main body 10 near urine drains position is protected Maintain an equal level exhibition, so improve the absorbent properties of urine, and also is prevented from because absorbing main body 10 Fold and the urethral leakage that causes.

And, in this embodiment, in veutro band member 20, with absorb main body 10 The discontinuous layout of veutro elastic component 23 in overlapping gamut.But, the present invention is not It is confined to this.Such as, the abdomen on crotch side it is positioned in a longitudinal direction relative to bound fraction 40 The part only overlapped with absorption main body 10 of side elastic component 23 can include its Elastic structure Part 23 is along the part of the discontinuous layout of horizontal direction.Even if in this case, it is also possible to Decrease uptake main body 10 is shunk in a longitudinal direction relative to bound fraction 40 on crotch side. And, it is disposed relative to bound fraction continuously along horizontal direction with veutro elastic component 23 The 40 veutro band members 20 being positioned in a longitudinal direction in crotch side along the two of horizontal direction Situation between individual end sections is compared, and alleviates and transports leg because of veutro extension 20B Dynamic restriction, and therefore can strengthen the mobility of wearer leg.

It should be noted that the structure of dorsal part elastic component 33 and the structure of veutro elastic component 23 Make identical.Briefly, in DLZ component 30, do not overlap with absorption main body 10 In part, dorsal part elastic component 33 is arranged continuously along horizontal direction, and with absorb main body In 10 overlapping parts, dorsal part elastic component 33 is along the discontinuous layout of horizontal direction.Therefore, Absorb main body 10 also keeps open and flat with the overlapping part of DLZ component 30, it is therefore prevented that print Word etc. in part 13b overlapping with DLZ component 30 of sheet material is difficult to be seen overleaf See, and therefore prevent diaper 1 to be worn as mistakenly putting the cart before the horse.But, the present invention is also It is not limited to this.Such as, it is positioned in a longitudinal direction on crotch side relative to bound fraction 40 Veutro elastic component 23 and dorsal part elastic component 33 can be arranged in continuously along horizontal direction Between veutro band member 20 and two end sections along horizontal direction of DLZ component 30.

Additionally, the veutro band structure being positioned in a longitudinal direction on crotch side relative to bound fraction 40 The part (veutro extension 20B) of part 20 contractility in a lateral direction higher than relative to Part (the back of the body of the DLZ component 30 that bound fraction 40 is positioned on crotch side in a longitudinal direction Extension, side 30B) contractility in a lateral direction.To this end, in the present embodiment, abdomen Side elastic component 23 be arranged (fixing) in the 20B of veutro extension time ratio of elongation The example factor is higher than dorsal part elastic component 33 prolonging when being arranged in the 30B of dorsal part extension Stretch scale factor.Extending scale factor is such index, described exponential representation elastic component 23, 33 extend how many times from its natural length, and are defined as by being in the bullet in extension state The length (LS) of property component 23,33 divided by the elastic component 23 being in non-extended state, The value (=LS/L0) that length L0 (natural length) of 33 is obtained.It addition, such as, veutro The veutro elastic component 23 of extension 20 can dorsal part than dorsal part extension 30B elastic Component 33 is thick, the veutro elastic component 23 of veutro extension 20B in a longitudinal direction Interval can dorsal part elastic component 33 than dorsal part extension 30B in a longitudinal direction It is spaced narrow, and is positioned at the contraction of veutro elastic component 23 near the 20B of veutro extension Power can be higher than the contractility of the dorsal part elastic component 33 being positioned near the 30B of dorsal part extension.

In other words, the veutro extension 20B's after shrinking due to veutro elastic component 23 Along horizontal direction length and perisystolic veutro extension 20B along horizontal direction Ratio between length is less than the dorsal part extension 30B after shrinking because of dorsal part elastic component 33 The length along horizontal direction and perisystolic dorsal part extension 30B along horizontal direction Length between ratio.Therefore, the adhesive-bonded fabric 21,22 of veutro band member 20 is constituted at horizontal stroke The adhesive-bonded fabric 31,32 of the length on direction and composition DLZ component 30 is at horizontal direction On length equal, and as shown in Figure 6, in the naturalness of diaper 1, along longitudinal side To the veutro extension 20B being positioned on crotch side along horizontal direction relative to absorb main body The lateral length Le of 10 end edge 20BE being positioned on side can be than position in a longitudinal direction Dorsal part extension 30B on crotch side along horizontal direction relative to absorb main body 10 The lateral length Lf of end edge 30BE being positioned on side is short.Thus, it is possible to make diaper The shape of 1 is close to the shape of general underpants.As a result, it is possible to prevent diaper 1 with further determining that Be worn as mistakenly putting the cart before the horse, even and if user not can confirm that the literary composition being printed on diaper 1 Words etc., are also easy to distinguish the front and rear of diaper 1.It addition, leg-openings 1HL is extended, Therefore when dressing diaper, veutro band member 20 is not easy to wale the lower limb of wearer.Thus, it is easy to Dress diaper 1, and the movable range of the leg of wearer can be expanded.Meanwhile, dorsal part prolongs Extending portion divides 30B length in a lateral direction to keep longer, therefore can strengthen wearer The covering performance of buttocks.But, the invention is not limited in this, and dorsal part extension 30B The contractility along horizontal direction can than veutro extension 20B along horizontal direction Contractility is big.

Additionally, the veutro elastic component 23 being arranged in the 20B of veutro extension and being arranged in Dorsal part elastic component 33 in the 30B of dorsal part extension to diaper 1 about the adaptation of wearer Performance impact is less, described veutro extension 20B be so that diaper 1 front and rear it Between have discrepant part.Then, in the diaper 1 of the present embodiment, relative to bound fraction The 40 veutro elastic component 23 being positioned in a longitudinal direction on crotch side and dorsal part elastic components 33 Respective danier (denier) (thickness), i.e. the veutro bullet of veutro extension 20B Property component 23 and dorsal part extension 30B dorsal part elastic component 33 respective danier want The veutro elastic component 23 overlapping with bound fraction 40 in a longitudinal direction less than (being thinner than) and The respective danier (thickness) of dorsal part elastic component 33, i.e. the veutro of veutro main body 20A The respective danier of the dorsal part elastic component 33 of elastic component 23 and dorsal part main body 30A.

Therefore, it can the lateral side elastic component 23 by veutro main body 20A and dorsal part main body The dorsal part elastic component 33 of 30A strengthens the diaper 1 Adapter Property about wearer, simultaneously can Make it difficult to apply the veutro elastic component 23 of veutro extension 20B and the back of the body on the wearer The trace (traces) (trace of elastic threads) of the dorsal part elastic component 33 of extension, side 30B. Particularly because its leg is generally moved to veutro by the mankind, so veutro extension 20B The danier of veutro elastic component 23 lower, thus alleviate 20B pair, veutro extension The restriction of leg exercise, and the leg mobility of wearer can be strengthened.
