The leakage suppression of===sanitary napkin===
Fig. 4 A are the figures for the cross sectional shape for representing the sanitary napkin 1 under nature, and Fig. 4 B are the sanitary napkins 1 when representing wearing
Cross sectional shape figure.In addition, Fig. 4 A and Fig. 4 B are in the width direction and thickness direction splits the length direction of sanitary napkin 1
Central portion 1b sectional view.For the sanitary napkin 1 of present embodiment, as shown in figure 1, in the central portion of length direction
1b, length of second 3 length (between 3b, 3b) in the direction of the width than absorber 4 in the direction of the width (between 4a, 4a)
It is long.In addition, the middle position alignment of the width of second 3 and absorber 4, therefore, as shown in Figure 3 B, the width of second 3
A part for the double portion 30 that the end in degree direction is turned back is located at the outside of width compared to absorber 4.
In this, it is assumed that the central portion 1b of the length direction in sanitary napkin 1, second 3 and absorber 4 are in the direction of the width
Equal length, second 3 outside for not reaching width from absorber 4.In this case, sanitary napkin 1 (main part 11)
Width both sides rigidity be increased to it is equal with the rigidity of the central portion of width.Therefore, pressed from both sides in sanitary napkin 1
Enter the crotch part of wearer and so that the hip crotch for wanting the inboard compression sanitary napkin 1 to width tightens power (leg-
Tightening force) effect when, the both sides of the width of sanitary napkin 1 are compressed backward skin side and turned up or to non-skin
Turn up skin side.That is, wearing when the deformation of sanitary napkin 1 become unstable.If the both sides of the width of sanitary napkin 1 are to non-skin
Skin side is turned up, then gap between the central portion of the width from sanitary napkin 1 and introitus is overflowed excreta or in width
In the case that the excreta that the central portion in degree direction has not absorbed flows out in the direction of the width, it is impossible to the width side of sanitary napkin 1
To both sides block excreta, probably excreta can be caused to be leaked from sanitary napkin 1.
In addition, it is assumed that the both ends of the width of second 3 are not turned back and so that reaching width side from absorber 4
To second 3 of outside be individual layer.It is the unit area weight that can play this degree of liquid permeability due to needing to make second 3
Amount and thickness, therefore, in this case, the rigidity of the both sides of the width of sanitary napkin 1 and the central portion of width
Rigid phase ratio become too low.Therefore, when hip crotch tightens power and acts on sanitary napkin 1, the both sides of the width of sanitary napkin 1
Crumpled, be converted into various shapes.It is thus impossible to blocked with the both sides of the width of sanitary napkin 1 in width side
The excreta flowed upwards out, probably excreta can be caused to be leaked from sanitary napkin 1.
By contrast, for the sanitary napkin 1 of present embodiment, as described above, in the central portion 1b of length direction,
A part for the double portion 30 that the end of the width of two 3 is turned back is located at the outside of width compared to absorber 4.Cause
This, the rigidity of the both sides of the width of sanitary napkin 1 (main part 11) when absorber 4 be present compared with step-down, but not mistake
As little as from absorber 4 stretch out second 3 be individual layer when degree.Accordingly it is possible to prevent the change deformation of the sanitary napkin 1 during wearing
The both sides for obtaining unstable or the sanitary napkin 1 in wearing width are crumpled.Moreover, as shown in Figure 4 B, health can be made
The both sides of the width of towel 1 are that starting point erects to skin side with the first compression unit 7.
Because：For the sanitary napkin 1 of present embodiment, the rigidity of the both sides of width absorbs with existing
The situation of body 4 is compared to low, also, the both sides in width is to be located at second 3 that skin side is leaned on than absorber 4,
Therefore, by setting the first compression unit 7 on sanitary napkin 1, in its natural state (Fig. 4 A), the two of the width of sanitary napkin 1
Sidepiece is also that starting point is somewhat turned up to skin side with the first compression unit 7.Especially, as the sanitary napkin 1 of present embodiment,
In the case of alar part 10, alar part 10 is turned back to underwear, thus, the both sides of the width of the main part 11 of sanitary napkin 1
Portion is located at the thigh root of underwear.In this case, if also assuming that, absorber 4 is in the both sides of the width of sanitary napkin 1,
The power of the thigh root for the underwear for being then intended to be close to wearer is offset by the rigidity of absorber 4, therefore, the both sides of width
It is difficult to erect to skin side.But for the sanitary napkin 1 of present embodiment, because the both sides of width are not present
Absorber 4, therefore, by the thigh root of underwear, the power that the both sides of width are intended to erect to skin side is promoted.Cause
This, according to the sanitary napkin 1 of present embodiment, in wearing, can make the both sides of the central portion 1b of length direction width
Portion is stable and is gracefully erected to skin side, and the cross sectional shape of sanitary napkin 1 can be made to be deformed into W shapes.
So, in wearing, the central portion 1b of the length direction of sanitary napkin 1, the position abutted with introitus periphery become
Shape is W shapes, so as to so that the central portion of the width of sanitary napkin 1 (main part 11) is close to introitus, and it is possible to
Block the excreta flowed out in the direction of the width in the both sides of the width of sanitary napkin 1.Therefore, excreta can be suppressed from defending
Raw towel 1 leaks.In addition, when the cross sectional shape of sanitary napkin 1 is W shapes, sanitary napkin 1 also easily with from labia majora to pars inguinalis
Introitus periphery coincide, and gap between wearer and sanitary napkin 1 reduces, therefore can alternatively suppress excreta from defending
Raw towel 1 leaks.In addition, the fit by improving sanitary napkin 1, can bring reassurance to wearer.
Even if in addition, do not turn back second 3 width both ends, such as by increasing the unit plane of second 3
Product weight and thickness, tighten the masterpiece used time, the both sides for being also possible to prevent the width of sanitary napkin 1 are crumpled in hip crotch.But
It is, in this case, central portion in the width of sanitary napkin 1, the position abutted with introitus, the unit of second 3
Area weight and thickness also increase, and cause to reduce from top flat 2 to the liquid permeability of absorber 4.Similarly, even if second 3 has
The weight per unit area and thickness of this degree of liquid permeability can be played, if the position turned back of second 3 is each other in thickness
It is overlapping on direction, i.e. second 3 do not have an individual layer portion 31, then it is saturating at the central portion for the width for also resulting in sanitary napkin 1
Fluidity reduces.Then, as in the present embodiment, the both ends of the width of second 3 are turned back, and makes second 3
The central portion of width be individual layer portion 31.So, the both sides of the width of sanitary napkin 1 can be made to skin side
Erect, and it is possible to ensure the liquid permeability of the central portion of width.Accordingly it is possible to prevent width of the excreta from sanitary napkin 1
The central portion in direction overflows, and can suppress excreta and be leaked from sanitary napkin 1.
In addition, absorber 4 can also be coated by the covering material (such as tissue sheets etc.) of liquid permeability, in the length of sanitary napkin 1
The central portion 1b in direction is spent, the length of covering material in the direction of the width can also be with second 3 length in the direction of the width
It is identical.In this case, because the rigidity of covering material is lower than the rigidity of absorber 4, therefore the width of sanitary napkin 1 will not also be hindered
The both sides in degree direction erect to skin side.
In addition, for the sanitary napkin 1 of present embodiment, as shown in figure 1, in the central portion 1b of length direction, absorb
The end 4a of the width of body 4 bends to the inner side protrusion to width.That is, with the middle position for tending to length direction
B, the width of absorber 4 become narrow gradually, the middle position B of length direction and between being separated in the longitudinal direction with middle position B
Every position (such as position A) compare, the narrowed width of absorber 4.Therefore, absorber 4 is easily along the huckle of wearer,
The both sides of the width of sanitary napkin 1 easily erect to skin side.No matter in addition, on the width length direction of second 3
How all constant position is, therefore, in the central portion 1b of length direction, can increase what is stretched out in the direction of the width from absorber 4
The length of second 3.Therefore, the sanitary napkin 1 abutted with introitus periphery length direction central portion 1b, can be with more reliable
Ground makes the both sides of the width of sanitary napkin 1 be erected to skin side, can block the excreta flowed out in the direction of the width.
For the sanitary napkin 1 of present embodiment, in the central portion 1b of length direction, absorber 4 is in width
Degree is shunk on direction, and the double portion 30 of second 3 is stretched out in the direction of the width from absorber 4.Therefore, the huckle warp of wearer
Contacted by second piece 3 faces lower than absorber 4 with rigidity (hard sense) of top flat 2.Also, in the present embodiment, make second 3
For the higher piece of elasticity.Therefore, the resiliency of the both sides of the width of sanitary napkin 1 is high, and the hip crotch from wearer stretches tight
Clamp force is relaxed by second 3, also weakens to the bounce of wearer.Therefore, according to the sanitary napkin 1 of present embodiment, with it is big
In the case of students in middle and primary schools' wearing of the people compared to the wearing of uncomfortable sanitary napkin, sense of discomfort during wearing can also be reduced.Change speech
It, the hip crotch width compared with adult it is small students in middle and primary schools wearing in the case of, can by from absorber 4 in the direction of the width
Second 3 stretched out adjusts the width of sanitary napkin 1, therefore sense of discomfort when can also reduce wearing.
In addition, the face of the side of second 3 rigidity compared with the face of opposite side increases sometimes.For example, it is gas at second 3
In the case of viscous formula non-woven fabrics, during fabrication with the net surface of net contact compared with the face of opposite side, fibre density increases, rigidity
Increase.So, when in the case where the two-sided rigidity of second 3 is different, as shown in figure 3, by the both ends of width to non-
Skin side is turned back so that the high face of the rigidity of second 3 is in inner side, and thus, the high face of rigidity will not expose to wearer side,
It can only make rigidity low facing to wearer side.I.e., it is possible to only make the resiliency of second 3 high facing to wearer side,
Therefore sense of discomfort during wearing can further be reduced.
In addition, second 3 prevents liquid from the liquid that absorber 4 is absorbed is flow backwards or improved from absorber 4 generally for playing
Act on and set as the disguise of body.By making such second 3 both sides for also functioning to the width for making sanitary napkin 1
Portion erects or increased the effect of resiliency to skin side, for example, being arranged on will differ from the new chip part of second 3 than inhaling
Acceptor 4 by the outside of width position so that it plays a part of erecting is compared with the situation of resiliency, can simplify
The structure of sanitary napkin 1, cost degradation can be sought.
In addition, for the sanitary napkin 1 of present embodiment, as shown in figure 1, in the central portion 1b of length direction, first
The end 4a of width of the compression unit 7 along absorber 4 bends to the inner side protrusion to width, the center of length direction
Position B is with the longitudinal direction compared with the position (such as position A) of middle position B intervals, a pair of first compression units 7
Width narrower intervals.Therefore, defended as the first compression unit 7 for erecting starting point easily along the huckle of wearer
The both sides of the width of raw towel 1 easily erect to skin side.In addition, the central portion 1b of the length direction in sanitary napkin 1, can
To increase the length of second 3 stretched out in the direction of the width from the first compression unit 7.Therefore, abutting with introitus periphery
The central portion 1b of the length direction of sanitary napkin 1, it can more reliably make the both sides of the width of sanitary napkin 1 edge-on to skin
Rise, erect height furthermore it is possible to increase, therefore, the excreta flowed out in the direction of the width can be blocked.
Protruded in addition, the first compression unit 7 is bent to the inner side of width, and the position turned back of second 3
The end 3a (hereinafter referred to as turn back end 3a) of the inner side of width is alongst.Therefore, in including length direction
The defined section (between Fig. 1 CC) of length direction including the position B of centre, as shown in Figure 3 B, the end 3a phases of turning back of second 3
Than the outside that the first compression unit 7 is located at width.On the other hand, with the middle position B of length direction in the longitudinal direction
Position (such as position A) place of interval, as shown in Figure 3A, the end 3a that turns back of second 3 are located at width compared to the first compression unit 7
Spend the inner side in direction.
Therefore, the length direction including the middle position B including length direction defined section (Fig. 1 CC it
Between), the double portion 30 of second 3 will not be pressed on absorber 4 by the first compression unit 7, therefore, easily from absorber 4 to skin
Swell side.That is, at the position abutted with introitus periphery, the both sides of the width of sanitary napkin 1 can be made grand to skin side
Rise, therefore, can more reliably block the excreta flowed out in the direction of the width.Further, since relative to from labia majora to abdomen
The fit of the introitus periphery in butt crack portion improves, therefore can alternatively suppress excreta and be leaked from sanitary napkin 1.It is another
Aspect, in the opening position with the middle position B of length direction intervals in the longitudinal direction, the double portion 30 of second 3 is borrowed
The first compression unit 7 is helped to be integrally formed with absorber 4, therefore, even if second 3 is the higher piece of elasticity, the two of width
The state that end is turned back also is maintained.In addition, for example, in the situation that the length of absorber 4 in the longitudinal direction is 195mm
Under, the end 3a that turns back of second 3 is located at the section (between Fig. 1 CC) in outside in the longitudinal direction compared to the first compression unit 7
Length for 30mm~50mm just.
Fig. 5 is the figure for the thickness for illustrating sanitary napkin 1.For the sanitary napkin 1 of present embodiment, in its natural state,
Thickness (length on the thickness direction) t1 at the position formed with the first compression unit 7 is by width than the first compression unit 7
Less than half of the maximum gauge t2 at the position in outside.In addition, in the present embodiment, the first compression unit 7 has low compression portion
70 and high compression portion 71, each thickness of low compression portion 70 and high compression portion 71 is all by the outer of width than the first compression unit 7
Less than half of the maximum gauge t2 at the position of side.So, as shown in figure 5, leaning on the space of skin side than the first compression unit 7
Become big, therefore, tightened the masterpiece used time in hip crotch, the both sides of the width of sanitary napkin 1 easily erect to skin side.Change speech
It, the position for more leaning on non-skin side, therefore, the two of the width of sanitary napkin 1 are located at as the first compression unit 7 for erecting starting point
Sidepiece easily erects to skin side.Therefore, the excreta flowed out in the direction of the width can more reliably be blocked.
In addition, for the sanitary napkin 1 of present embodiment, as shown in Fig. 2 the end 3b of the width of second 3,
Compared to being provided with the first bonding agents 20 for the main part 11 being applied to beyond alar part 10, fixed in its skin-side surface of underwear
The end 20a of the width in the region of the first bonding agents 20 (bonding agent) of sanitary napkin 1 is located at the outside of width.That is,
The part for playing the region residing for second 3 of the vertical role in both sides for the width for making sanitary napkin 1 is not fixed
In underwear, movement is not limited by underwear.Therefore, the both sides of the width of sanitary napkin 1 easily erect to skin side, Ke Yigeng
Reliably block the excreta flowed out in the direction of the width.
