<Manufacture diaper 1>
Then, the method that manufacture diaper 1 will be briefly described.Fig. 4 is to show the exemplary letter of the manufacturing process of diaper 1
Figure.
In this illustration, diaper 1 is manufactured, so that for use as material while transporting substrate sheet along carriage direction
Substrate sheet implement predetermined process (S101 to S105).Hereinafter, the carriage direction of sheet element is referred to as " direction MD ", and just
The direction for meeting at the direction MD is referred to as " direction CD ".The direction MD be along the direction of the longitudinal direction (vertical direction) in Fig. 2A,
And the direction CD is the direction along the transverse direction in Fig. 2A.
In the first embodiment, the sheet element for constituting the substrate sheet of diaper 1 is that absorbent main body serialgram 10A and side are continuous
Piece 40A.Absorbent main body serialgram 10A is such sheet element, so that multiple absorbent main bodies 10 are (vertical in a longitudinal direction
Direction) continuous arrangement.That is, absorbent main body serialgram 10A is with the morphogenetic sheet element of this shape, so that multiple absorbers 11
It is clipped between the serialgram of top sheet 13 and the serialgram of tergite 15 extended along the direction MD along thickness direction.Similarly,
Side serialgram 40A is such sheet element, so that forming the lateral plate 40 of leg rivel part 20 and band part 30 along longitudinal direction
Direction (vertical direction) continuous arrangement.
Firstly, as shown in figure 4, absorbent main body serialgram 10A will be at it along the two of the direction CD (transverse direction)
(S101) is continuously transported along the direction MD with the substrate sheet in the state of side serialgram 40A connection on side.
Then, for the substrate sheet being just transported, the leg rivel cut out portion 25 of leg opening HL is constituted and with notch
Part 35 is formed on the two sides in the direction CD (transverse direction) of absorber 11 respectively across (S102) at the position of broken line FL.
These cut out portion are formed using unshowned cutting roller etc..It should be noted that using the state pair of the S102 processing in Fig. 4
The state of its unfolded unfolded state in Fig. 3 A should be in diaper 1.
Then, (horizontal along the direction CD at broken line FL corresponding to each part of the band part 30 in the serialgram 40A of side
To direction) fold inward, so that a part of absorbent main body 10 and each leg rivel part are all along thickness direction and band
Part 30 is overlapped (S103).
Then, the first linking portion WL1 and second is formed by the linking method of such as ultrasonic welding or thermal welding to connect
Knot divides WL2, so that band part 30 is attached to absorbent main body 10 and leg rivel part 20 (S104).First linking portion
WL1 and the second linking portion WL2 is formed so that inclination angle theta 1, θ 2 meet predetermined condition as described above (1 > θ 2 of θ).
Next, cutting substrate sheet (S105).Specifically, urine is individually cut into from along the continuous substrate sheet in the direction MD
Cloth 1.In addition, cutting away the four corners of each rectangle along the first linking portion WL1 and the second linking portion WL2.Therefore, shape
At the diaper 1 being in shown in Fig. 2A in flat condition.
<The stickiness etc. of diaper 1>
Diaper 1 according to an embodiment of the present disclosure has various constructions, and wearer is enabled to feel to be bonded when wearing
It obtains more excellent.Particularly, implement to adjust to the position of leg opening HL is formed, to improve leg circumferences compared with conventional diaper
Stickiness and promotion at part distinguish the front and back of 1 appearance of diaper.It will be described below these contents.
Fig. 5 is the schematic diagram for explaining the arrangement of the leg opening HL in diaper 1.Fig. 5 is shown to be opened up in diaper 1
It opens the leg opening HL in the flat condition as shown in Figure 3A and is arranged in the enlarged view on right side along transverse direction.
In diaper 1 according to an embodiment of the present disclosure, before leg opening HL is arranged so that the longitudinal direction of leg opening HL
Distance glf between end position HLef and longitudinal front end portion 10ef of absorbent main body 10 in a longitudinal direction is less than leg
Between the longitudinally aft end position HLer of opening HL and longitudinal front end portion 10er of absorbent main body 10 in a longitudinal direction
Distance glr.That is, leg opening HL is arranged into front side, and the longitudinally central location CLh1 phase of leg opening HL in a longitudinal direction
Front side on longitudinal direction is navigated to for the longitudinally central location CL of absorbent main body 10.
Because leg opening HL along the longitudinal direction of diaper 1 be arranged into front side, when wearer wears diaper 1
The leg for preventing leg opening HL from hindering wearer when his/her leg is moved to front is mobile.For example, being worn in wearer
Diaper 1 when walking, reduce that leg root is stuck at the circumferential edge portions of leg opening HL and leg cannot move easily
The problem of to front.In addition, by leg opening HL be arranged into front side indicate reduce in absorbent main body 10 relative to longitudinal direction
The opening area in the region on the rear side of central location CL.In other words, there is 1 fabric of diaper (absorbent main body 10) wherein
Partial area (surface area) is wider on rear side in a longitudinal direction.Therefore, on the back side of wearer more broadly
The buttocks for covering wearer, to improve stickiness when wearing diaper 1.
In addition, leg opening HL is arranged into front side and increases the surface area in the back side region of diaper 1, to promote
Distinguish the front and back of 1 appearance of diaper.This can minimize this problem, that is, it is degrading stickiness because diaper 1 wears backward,
Discharged liquid is easy to be leaked to the outside of diaper 1 from the space between the body and leg opening HL of wearer.
In addition, leg opening HL be arranged into a longitudinal direction front side and opening HL be formed as it is as shown in Figure 5 substantially
Ellipticity, to improve the stickiness of diaper 1.In Fig. 5, the leg rivel cut out portion 25 of leg opening HL is formed vertical
There is maximum width in a lateral direction at region between front end HLef on direction and rear end HLer.Specifically, leg
Easement curve is presented in portion's rivel cut out portion 25, and the easement curve profile is between front end HLef and rear end HLer along transverse direction
Direction is inwardly projecting, and leg rivel cut out portion 25 has maximum in a lateral direction near longitudinally central location CLh1
Width.Thus, it is supposed that W20 is the leg rivel part 20 in the region for forming leg opening HL (leg rivel cut out portion 25)
Width in a lateral direction, then W20 is minimum near longitudinally central location CLh1.When wearing diaper 1, the abdomen stock of wearer
Ditch portion is contacted with the region near centrally located CLhl.Therefore, leg rivel portion is reduced near the CLhl of central location
Divide 20 width W20 in a lateral direction, to minimize dry between leg rivel part 20 and wearer's pars inguinalis
It relates to.This enhances stickiness when wearing diaper and alleviates sense of discomfort.
Similarly, the region with cut out portion 35 between longitudinal front end HLef and rear end HLer of leg opening HL is formed
Locate that there is maximum width in a lateral direction.In Fig. 5, easement curve profile is presented in band cut out portion 35, and the mitigation is bent
Line profile protrudes outward between front end HLef and rear end HLer along transverse direction, and near longitudinally central location CLh1
With maximum width in a lateral direction.Therefore, thus, it is supposed that W30 is to form leg opening HL (band cut out portion 35)
Region at the width of band part 30 in a lateral direction, then W30 is minimum near longitudinally central location CLHl.Wearing diaper
Central location CLh1 is contacted with the region of wearer's hipbone (pelvis) nearby when 1, and central location CLhl is to work as to pull up
The region that wearer grasps and pulls in band part 30 when diaper 1.Therefore, the width in band part 30 in a lateral direction
In the case that degree reduces near the CLhl of central location, wearer can put on diaper 1 while tightly keeping band part 30,
To be easy to so that diaper 1 is bonded his/her body.In addition, because band part 30 is narrow in that region, diaper 1
Appearance closer to underpants shape.This can reduce wearer about the irresolute of dress " diaper " and/or contradict.
Additionally, it should be noted that each leg opening HL is Desirably formed so that it in a longitudinal direction
The opening area in the region on front side is greater than the opening area in the region that it is located in a longitudinal direction on rear side.In this public affairs
In the embodiment opened, in the width etc. of leg opening HL in a lateral direction being located in the region on front side in a longitudinal direction
In or greater than being located at leg opening HL width in a lateral direction in the region on rear side in a longitudinal direction, this with
The region on front side on longitudinal direction is opposite.In other words, inside in the front end HLef in a longitudinal direction with leg opening HL
At a predetermined distance at the position of h the width in a lateral direction of leg rivel cut out portion 25 and with cut out portion 35 in transverse direction
The summation of width on direction is equal to or more than in a longitudinal direction with the rear end HLer of leg opening HL inwardly at a distance of pre-
The width of leg cut out portion 25 in a lateral direction and the width with cut out portion 35 in a lateral direction at the position of set a distance h
The summation of degree.In the case where this shape, leg opening HL is wider on the abdomen side (front side) of wearer and in wearer
Back side (rear side) on it is relatively narrow.Therefore, when wearing diaper 1, leg is easy to move on front side, while being more likely on rear side
More broadly cover the buttocks of wearer.
In this case, at least it is being located in the region on front side in a longitudinal direction, it may be desirable to which leg rivel is cut
25 width in a lateral direction of oral area point is formed larger than the width with cut out portion 35 in a lateral direction.In other words, the phase
What is hoped is that the width of leg rivel cut out portion 25 in a lateral direction is greater than in a longitudinal direction and before leg opening HL
Hold the width at the position of HLef preset distance h spaced inward with cut out portion 35 in a lateral direction.It is very big on front side
Ground cuts off leg rivel cut out portion 25.Therefore, wearer will in the action process for wearing the diaper 1 for being configured to underpants form
When his/her leg is inserted into leg opening HL, toe is not easy to be captured by the preceding part of leg rivel part 25.Therefore,
It is easy to swimmingly wear diaper 1.In addition, because leg can be easily formed along leg circumferences shape after putting on diaper 1
Be open HL, so it is mobile to interfere leg easily, and can be realized such as the appearance of underpants (such as shorts and panties)
Fine appearance.
In addition, being arranged into the leg rivel elasticity of leg rivel part 20 in a longitudinal direction by adjusting in diaper 1
Positional relationship between component 23 and leg opening HL (leg rivel cut out portion 25) improves stickiness.In Fig. 5, in leg
Portion opening HL longitudinally central location CLhl at leg opening HL end edge portion be arranged in along transverse direction it is outermost
Longitudinal front side of the distance W23c less than leg opening HL between leg rivel elastic component 23 on side in a lateral direction
The end edge portion of leg opening HL and the leg rivel elastic component being arranged in along transverse direction in outermost at HLef
Distance W23f between 23 in a lateral direction.Similarly, distance W23c is less than at the longitudinally aft end HLer of leg opening HL
It the end edge portion of leg opening HL and is arranged between the leg rivel elastic component 23 in outermost along transverse direction
Distance W23r in a lateral direction.
Leg rivel elastic component 23 is arranged in the leg of the groin part of contact wearer close to each leg opening HL
At position near the central location CLhl of portion opening HL, thus the convergent force for being easy to be formed by leg rivel elastic component 23
It is applied on leg opening HL.This causes leg rivel part 20 to be easy to along the leg opening HL's near the CLhl of central location
End edge portion is shunk, so as to cause leg rivel to be easy to the adhered shape of the groin part along wearer.?
In this region, as mentioned above the width W20 of leg rivel part 20 in a lateral direction is narrow, so by leg rivel bullet
Property the convergent force that applies of component 23 can concentrate and be applied on leg rivel part 20.This minimize near the CLhl of central location
The ununiform shrinkage of the leg rivel part 20 at place, to limit the relaxation because generating at groin part and/or macrofold
Wearer is caused not feel like oneself.On the other hand, in two end sections HLef, HLer in leg opening HL, leg rivel
It is spaced far between elastic component 23 and leg opening HL.Therefore, disperse the end edge for being applied to leg opening HL easily
Convergent force on part.This minimize the excess shrinkages of leg rivel part 20, to be easy to cover buttocks and/or abdomen part
Domain.
Incidentally, it is formed in leg opening part such disposable between band part and leg rivel part
In diaper, due to its structure, stress is likely to be concentrated on the boundary part between leg rivel part and band part.So
Afterwards, if excessive stress is applied on boundary part when wearing diaper, diaper may be torn from non-woven fabrics etc..In root
In the case where diaper 1 according to embodiment of the disclosure, the boundary part between leg rivel part 20 and band part 30 is along leg
The longitudinal direction of portion opening HL is formed between front end HLef and rear end HLer.Therefore, stress is more likely to concentrate on these parts
On.
However, each leg rivel part 20 and each band part 30 are by same single sheet element (side in diaper 1
Piece 40) it constitutes.Therefore, linking portion etc. is not provided at boundary part (HLef, HLer) between them.Therefore, even if
Stress concentrates on this part, will not be easily formed rupture starting point.Therefore, it will not appear in easily when wearing diaper 1
The problem of tearing leg opening HL.
In addition, stretchable 43 is arranged to surround leg opening HL respectively, and this stretchable 43 in diaper 1
It is provided with shape opening identical with the shape of leg opening HL.This stretchable 43 enhances the circumferential edge of leg opening HL
Edge point, to prevent from tearing leg opening HL when wearing diaper 1.In addition, sheet stretchable 43 is arranged to and leg pleat
Pleat part 20 is overlapped, and so as to cause the smooth conjunction of circumference edge portion of leg opening HL, is thereby enhanced when wearing diaper 1
The feeling of leg rivel circumference.
In embodiment of the disclosure, as shown in figure 5, stretchable 43 20 side of leg rivel part in transverse direction
On width make the width W43c at longitudinally central location CLhl be less than longitudinal direction front end HLef at width W43f and longitudinal direction after
Hold the width W43r at HLer.Because stretchable 43 width reduces at longitudinally central location CLh1, it is not easy to point
Scatter the convergent force being applied on groin part, so as to enhance stickiness.On the other hand, in the end of leg opening HL
Increase stretchable 43 width at part HLef, HLer.Therefore, convergent force is applied to abdominal portion easily in wide scope
On seat portion.This can disperse the tensile force being applied in wearer's skin, be caused to minimize by over-tension
Sense of discomfort.
In addition, adjusting the inclination angle of the linking portion of connection absorbent main body 10 and leg rivel part 20 in diaper 1
(the first linking portion WL1 and the second linking portion WL2), to enhance the stickiness when wearing diaper.Fig. 6 A is to show to wear
When traditional pull-on disposable diaper.Fig. 6 B is to show diaper 1 according to first embodiment when wearing.
In traditional pull-on disposable diaper, the linking portion being formed on the front side (abdomen side) of diaper (corresponds to
The first linking portion WL1 of the present embodiment) and be formed in rear side (back side) linking portion (corresponding to the present embodiment second connect
Knot divides WL2) it is symmetrical generally about longitudinal direction.That is, linking portion is formed so that each preceding linking portion relative to longitudinal direction
The inclination angle in direction is equal to each rear inclination angle of the linking portion relative to longitudinal direction.In this case, it in underpants form, inhales
The angle that the property received main body is formed relative to band part is equal to each other between front side and rear side.As a result, as shown in Figure 6A, rear side
Absorbent main body on (back side) may be draped down when wearing diaper, and be easy to the buttocks in its diaper body and wearer
Between generate gap.In addition, wearer, which may realize that, has worn " diaper " because the appearance of buttocks side seems sagging,
This may make him/her not feel like oneself.
On the contrary, being adjusted in diaper 1, so that inclination angle theta 1 of each first linking portion WL1 relative to longitudinal direction
Inclination angle theta 2 (1 > θ 2 of θ) greater than each second linking portion WL2 relative to longitudinal direction.In this case, in underpants form
In, the angle formed between absorbent main body 10 and band part 30 may be larger and smaller on rear side on front side.As a result, such as
Shown in Fig. 6 B, when wearing diaper, rear side (back side) absorbent main body be pulled to wearer buttocks above, and urinating
Small gap is formd between cloth and the buttocks of wearer, to enhance stickiness.In addition, from the appearance, looking like
It wears underpants (such as shorts and panties), and seat portion seems that the differentiation of front and back fine and to diaper 1 becomes
It is easy.It is irresolute at dress " diaper " that this can minimize wearer.
It is to be noted that as shown in figure 5, embodiment of the disclosure is configured so that in a longitudinal direction on rear side
The distance between each leg opening HL and the end sections of absorbent main body 10 glr are larger, and in a longitudinal direction in front side
On each leg opening HL and absorbent main body 10 the distance between end sections glf it is smaller.Therefore, each second connection
Part WL2 is readily formed into smaller and each first connection on rear side in a longitudinal direction relative to the inclination angle theta 2 of longitudinal direction
Part WL1 relative to the inclination angle theta 1 that longitudinal direction is formed be readily formed into a longitudinal direction on front side it is larger.This make with
Width on front side (abdomen side) is compared, and may make the width of each band part 30 in a longitudinal direction on rear side (back side)
It is larger, and upward drawtape portion 30 is made it easy to, to realize the more excellent fitting in diaper 1.
In addition, as shown in Figure 3A, in diaper 1, the end sections of the first linking portion WL1 and the second linking portion WL2
Each of end sections will not intersect with leg opening HL.In other words, in each the first linking portion WL1
And predetermined space is set between leg opening HL described in each in the second linking portion WL2.If be configured so that
First linking portion WL1 (the second linking portion WL2) intersects with leg opening HL, then when wearing diaper 1, stress concentrates on this
On kind cross section, so as to form rupture starting point, this can make leg opening HL rupture easily.However, in basis
In the diaper 1 of the present embodiment, because leg opening HL does not intersect with linking portion, it is not easy to form rupture starting point,
And therefore leg opening HL is also not susceptible to rupture.
