===the present embodiment===

It is the explanation of the sanitary napkin 1 of an example of the absorbent commodity as present embodiment Figure.Diagrammatic top view when Fig. 1 is the sanitary napkin 1 from the skin side of thickness direction, Fig. 2 are from the non-of thickness direction Observe diagrammatic top view when same sanitary napkin 1 in skin side.In addition, Fig. 3 be III-III in Fig. 1 to regarding signal exploded view. In addition, diagrammatic top view when Fig. 4 is the absorber 10 from the non-skin side of thickness direction.

As shown in figures 1 and 3, sanitary napkin 1 is rectangular sheet component when looking down, has length direction, width side To and thickness direction.In addition, in the sanitary napkin 1, the top flat 20 of liquid permeability, the absorber 10 of absorbency and opaque liquid Tergite 30 is stacked gradually from skin side towards non-skin side in a thickness direction.Also, these components 20,10,30 pass through respectively The bonding agents such as hot-melt adhesive HMA is engaged with adjacent component in a thickness direction.Ω shapes pattern, spiral pattern, candy strip Etc. can be provided as the example of pattern wherein using the bonding agent HMA, and this be suitable for then describing other are viscous Meet agent HMA.

As shown in Figure 1, the planar dimension of top flat 20 and tergite 30 is more than the planar dimension of absorber 10.Therefore, the two Piece 20,30 respective outer peripheral edge portions 20e, 30e (referring to the dot pattern in Fig. 1) outside and width from absorber 10 to length direction It spends on the outside of direction and extends.Also, these outer peripheral edge portions 20e, 30e engage by crimping or bond by welding etc. so that absorber 10 are maintained between two pieces 20 and 30.

In this example, the flat shape of two pieces 20,30 is set to mutually the same.Also, two pieces 20,30 The substantially central portion of length direction is formed as the shape extended on the outside of two lateral width directions, as so-called alar part 1w, 1w, to Part 20w, 30w that outside extends are used to sanitary napkin 1 being positioned and secured to underwear (not shown).In other words, such as Fig. 2 and figure Shown in 3, the non-skin side of each part 30w corresponding with alar part 1w in tergite 30, with rectangular shape by appropriate Bonding agent formed adhesive portion 40w, for by sanitary napkin 1 be fixed to underwear.In addition, the wing in the non-skin side of tergite 30 Part 30c between portion 1w, 1w, alongst with multiple band-like adhesive portions for forming same purpose by bonding agent appropriate 40c.But the configuration pattern of these adhesive portions 40w, 40c is not limited to this.

As the material of top flat 20, the non-woven fabrics appropriate such as hot-wind nonwoven cloth can be enumerated, used here as hot-wind nonwoven cloth. But material is without being limited thereto.In other words, as long as soft liquid-permeable sheet, can also use other sheet materials.In addition, As the material of tergite 30, for example, the resin film appropriate such as polyethylene (PE), is used herein as PE films.But material It is without being limited thereto.That is, as long as soft opaque liquid piece, can also use other sheet materials.

In addition, as shown in Figure 1, multiple compression unit EM, EM... are formed from the skin side of the skin side of top flat 20, in thickness Top flat 20 and absorber 10 are compressed together to improve degree of engagement in degree direction.And it in this example, is compressed as these Portion EM is formed with two kinds of compression unit EML, EMD.A side in these compression units EM is linear compression unit EML.Also, it is more A these threadiness compression unit EML, EML... are formed as continuous along the outer peripheral edge of absorber 10, to generally form along length Spend the substantially annular shape that direction extends.And another party's compression unit EM is dotted compression unit EMD.And these dotted compression unit EMD, EMD... it is dispersedly formed in and is separated out substantially on top flat 20 by the multiple threadiness compression unit EML, EML... In closed region AEML.And in this example, the flat shape of each dotted compression unit EMD is the circle of a diameter of 1mm, And these compression units EMD, EMD... are placed in a manner of staggered.But, however it is not limited to this.It can be said that need not carry For these dotted compression unit EMD and linear compression unit EML.

As shown in Figure 3 and Figure 4, absorber 10 includes：Absorbent core 10c, by being formed as bowing absorbency fiber etc. Depending on the rectangular shape extended along its length when observation, as predetermined shape；With the core 10c same plane shapes The first emulsion sheet (being equivalent to liquid-permeable sheet) 11, contact and covered with the skin side of core 10c；With with the core The second emulsion sheet (being equivalent to second) 12 of 10c same plane shapes, contacts simultaneously with the non-skin side of core 10c It is covered.Moreover, as shown in figure 3, sheet material 11,12 passes through the bonding agents such as hot-melt adhesive HMA and absorbent core 10c mono- respectively It engages to body, sheet material 11,12 prevents absorbent core 10c's etc. to be not intended to change shaped like so-called wrinkle or conquassation as a result,.

Absorbent core 10c is with for exampleIn the range of weight per unit area Contain cellulose family absorbency fiber as absorbency fiber.This suction is illustrated using paper pulp fiber in this example Fluidity fiber, however it is not limited to this.For example, it is also possible to using rayon fiber, or other kinds of imbibition can be used Property fiber.

Moreover, in this example, other than absorbency fiber, the core 10c also contains for exampleThe super absorbent polymer (so-called SAP) of weight per unit area in range is lifted Example illustrates absorbency particle.But this SAP can also be omitted.

In addition, in this example embodiment, as the first emulsion sheet 11, use is with for example Range weight per unit area hot-wind nonwoven cloth, but not limited to this, as long as sheet material is soft liquid-permeable sheet. That is, other kinds of non-woven fabrics can also be used, thin paper etc. can also be used.For example, spun-bonded/melt-blown/spunbond (SMS) non-woven fabrics It is used as the second emulsion sheet 12, however, without being limited thereto as long as piece softness.That is, other kinds of non-woven fabrics can also be used, also Thin paper etc. can be used, alternatively, it is also possible to omit second emulsion sheet 12.

As shown in figure 4, in such absorber 10, dotted compression unit is also formed by compressing from non-skin side ED10.In other words, the absorber 10 in this example includes the first emulsion sheet 11, absorbent core 10c and the second emulsion sheet 12, because This, the compression unit ED10 is formed by compressing this three together in a thickness direction.And rigidity is thereby increased, to It can prevent the casual deformation of such as gauffer etc.And in this example, the flat shape of compression unit ED10 is straight Diameter is the circle of 1.2mm, and these compression units ED10, ED10... are placed in a manner of staggered.But, however it is not limited to This.The maximum gauge of the absorber 10 of these compression units ED10 and compression unit EML, EMD is wherein formed in such as 0.5mm to 5mm Within, however it is without being limited thereto.

In the present embodiment, the top flat 20 in Fig. 3, the liquid-permeable sheet contacted as the non-skin side with top flat 20 First emulsion sheet 11 of one example, absorbent core 10c and contacted as the non-skin side with core 10c second Second emulsion sheet 12 of an example respectively contain antiseptic.

Therefore, it is possible to effectively to remaining on the discharged liquid of top flat 20, the discharged liquid for remaining on the first emulsion sheet 11, absorbing The discharged liquid for being held in absorbent core 10c plays antibacterial action, therefore, it is possible in a wide range of interior of the thickness direction of sanitary napkin 1 Play antibacterial action.

In this example embodiment, the antiseptic of identical type is used for each 20,11,12 and absorbent core 10c arbitrary component. Therefore, it for the problem that 20,11,12 and 10c of these components, can prevent from occurring in the type difference of antiseptic (such as causing antibacterial action to reduce due to the haptoreaction between various types of antiseptics).But antiseptic is not limited to This.As long as that is, selection and using a variety of antiseptics not reduce antibacterial action, such as even if antiseptic connects each other It touches also without any reaction etc., the type of antiseptic can be different according to 20,11,12 and 10c of component.

As such antiseptic, it can be used for example and obtained by diluting Benza with appropriate solvents such as water Antimicrobial fluid.Specifically, the antimicrobial fluid can by Benza is diluted to 5% aqueous solution, second alcohol and water Respectively with 0.25%, 10% and 89.75% ratio combines and generates.In this example, using this antimicrobial fluid.Then, When sanitary napkin 1 is supplied to market, the solvent of such as water has evaporated.As a result, at each 20,11,12 and absorbent core 10c Inside, become benzalkonium chloride as main antimicrobial component remaining state.The portfolio ratio and ingredient are an examples, and It is without being limited thereto.That is, antimicrobial fluid can be generated with other portfolio ratios and ingredient.In addition, in addition to the antimicrobial fluid it Outside, cetylpyridinium chloride, benzethonium chloride, polyaminopropyl biguan-ide, p-hydroxybenzoate etc. can be used as anti- Microbial inoculum.

Here, for the amount (residual after solvent volatilization of the antiseptic contained by each 20,11,12 and absorbent core 10c Measure (g)) magnitude relationship, in this example, top flat 20 is maximum, and the first emulsion sheet 11 times is big, and absorbent core 10c takes second place, second Emulsion sheet 12 is minimum.

Then, as long as the amount (g) for the antiseptic for including in top layer 20 is maximum, so that it may to increase the work of the antibacterial in top layer 20 With.Therefore, it is possible to applying big antibacterial action from the discharged liquid for being discharged to sanitary napkin 1 in early days.As a result, sanitary napkin 1 is generally High antibiotic property can be provided.

But the invention is not limited thereto.Include the maximum amount of antiseptic for example, it can be absorbent core 10c.Then, This can apply the drained liquid in absorbent core 10c high antibacterial action, and most of discharged liquid is most in absorbent core 10c Maximum duration is kept at last.Therefore, even in this case, sanitary napkin 1 also can generally provide high antibiotic property.

When using the antimicrobial fluid from Benza as antiseptic, can judge as follows each Whether a piece 20,11,12 and absorbent core 10c include antiseptic.First, sanitary napkin 1 is being decomposed into each 20,11,12 After the unit of absorbent core 10c, for each 20,11,12, absorbent core 10c, bromophenol blue alkaline solution (is mixed with The bromophenol blue aqueous solution 20mL of the sodium hydroxide reagent 50mL and 0.05% of 0.1mol/L) it is used as test reagent, it is sprayed at respectively On 20,11, the 12 and 10c of each component of subjects.Then, when the color of the reagent becomes au bleu from purple, it may be determined that 20,11,12 and 10c of these components includes antiseptic.Instead of the reagent, (can also be mixed with using bromophenol blue acid solution The bromophenol blue ethanol solution 2mL of the acetic acid 92.5mL and 0.1% of sodium acetate 7.5mL, 0.2mol/L of 0.2mol/L).This In the case of, when the color of reagent becomes au bleu from yellow, it is possible to determine that including the antiseptic.In some cases, antibacterial The magnitude relationship of the amount of agent can be judged based on the depth of color after change.

Fig. 5 is shown in the antiseptic by dot pattern plan-position specified in width direction and length direction Domain of the existence AR.In this example embodiment, substantially, domain of the existence AR substantially phases on each 20,11,12 and absorbent core 10c Together.Therefore, them are represented here, will describe the domain of the existence AR of the antiseptic on top flat 20.

In this example embodiment, the domain of the existence AR of antiseptic is set throughout the whole length of the length direction of top flat 20.But It is that antiseptic is not the endlong setting for spreading width direction there are field AR.That is, the domain of the existence AR of antiseptic is set In the central portion 20cw of width direction, rather than each end 20ew, 20ew of width direction.Then, this, which restrained effectively, wears The skin of the crotch of user is damaged.Details are as follows.

Firstly, since each end 20ew in the width direction of top flat 20 is the abdomen stock that possible contact at the crotch of wearer The part of ditch, so for example skin especially these ends 20ew may be damaged by the skin for the wearer that rubs.Therefore, if There are antiseptics at the 20ew of these ends, then the damage may increase.In this respect, in this example, these ends 20ew is the non-domain of the existence ARN there is no antiseptic.Therefore, the increase of the damage can be inhibited.

But the invention is not limited thereto.That is, the width in top flat 20 can be arranged in the domain of the existence AR of antiseptic In the whole length in direction.

In the example of fig. 5, domain of the existence AR is set at domain of the existence from absorbent core 10c in width direction and length In the range that direction protrudes.Therefore, when the final absorbability core 10c of discharged liquid absorbs, though discharged liquid in width direction and Any position on length direction is absorbed, and can also apply antibacterial action to the discharged liquid.Therefore, sanitary napkin 1 generally may be used To provide high antibiotic property.

In addition, in this example embodiment, antiseptic exists in domain of the existence AR with almost impartial distribution.But antibacterial Agent there are without being limited thereto.That is, at domain of the existence AR, compare width at the central portion Arc that antiseptic can be in the direction of the width It is more at end Are, ARe on direction.Therefore, it is possible to more effectively big to the discharge rate of the central portion ARc of width direction Discharged liquid assigns antibacterial action.

On the contrary, in this example, this antiseptic is on the thickness direction of top flat 20 and unequal.That is, shown in Fig. 3 On the thickness direction of top flat 20, compared with the part of skin side, there are a large amount of antiseptics for the part of non-skin side.Then, this The damage of wearer's skin can also be effectively prevented.But the invention is not limited thereto.That is, will not be caused to skin in use In the case of dysgenic antiseptic, which can be in the whole length of the thickness direction of top flat 20 almost equably In the presence of or antiseptic skin side of the amount on the thickness direction of top flat 20 part it is more than the part of non-skin side.

In this example, as described above with reference to Figure 1, top flat 20 and absorber 10 (11,10c and 12) in a thickness direction from Skin side is pressed together.This results in concave dotted compression unit EMD and linear compression unit EML.These compression units EMD, There is also antiseptics at EML.Therefore, when discharged liquid is discharged to the skin side of top flat 20, antibacterial action can also it is rapid and Effectively it is applied to the discharged liquid that compression unit EMD, EML are likely to accumulate in due to the shape of recess.Then, this also effectively has Help sanitary napkin 1 and generally high antibiotic property is provided.

Here, as the fiber distribution density (g/cm for comparing the first emulsion sheet 11 at compression unit EMD, EML³) (hereinafter referred to as For fibre density (g/cm³)) and the second emulsion sheet 12 fibre density (g/cm³) when, the preferred fibre density of the second emulsion sheet 11 It is larger.It therefore,, can be easily defeated by fluid antimicrobial agent using capillarity in the manufacturing line LM of aftermentioned sanitary napkin 1 It is sent on the second emulsion sheet 12.As a result, a wide range of interior in the presence of anti-on the thickness direction that can be formed at compression unit EMD, EML The state of microbial inoculum.Therefore, it is possible to more effectively assign antibacterial action to the discharged liquid for being accumulated in compression unit EMD, EML.

At compression unit EMD, EML, each 20,11 and 12 and absorbent core 10c fibre density (g/cm³) it is each A value, for example, can as by 20,11, the 12 and 10c of each component of computing object compression unit EMD, EML unit area weight Measure (g/m²) divided by 20,11,12 and 10c of each component obtained by the thickness of compression unit EMD, EML except calculation value carries out asking calculation.

Preferably, the first emulsion sheet 11 has the coloured part coloured with the color different from its material color (not shown).In this example, since the first emulsion sheet 11 is non-woven fabrics, material color is white, and the first emulsion sheet 11 has The coloured part of the green of the color different from white.In addition, in this example, it, should in order to improve the visuality of the coloured part Coloured part is formed in the whole region of the skin side of the first emulsion sheet 11.Then, make the coloured part for seeing the green It is such impression of antibacterial that people, which has the sanitary napkin 1,.But the color of coloured part is not limited to green.As long as that is, giving The color for the such impression for seeing that the people of coloured part with the sanitary napkin 1 is antibacterial is given, coloured part can use other type Color dyes.For example, it is color that color, which can be such as green of yellow green or bottle-green other type, or can be Blue series color.It is whole at the skin side for the first emulsion sheet 11 that the formation target area of coloured part is not limited to the described above A region.For example, the formation target of coloured part can be a part for identical skin side.

In manufacturing line LM, first, the multiple absorbers 10 manufactured in the process of lower part, 10... are being conveyed It is conveyed on transport path such as belt conveyer CV with scheduled spacing P1 on direction.That is, at this point, due to absorber 10 It is formed, so the first emulsion sheet 11 is by the skin engagement sides of hot-melt adhesive HMA etc. and absorbent core 10c, and Second emulsion sheet 12 passes through hot-melt adhesive HMA etc. and non-skin engagement sides.

Moreover, the continuous sheet 20a (being equivalent to " substrate sheets of top flat ") of top flat on same transport path as defined in Converge position Pj20a to converge, it is continuous along its length that continuous sheet 20a is configured to multiple top flats 20,20....It is absorbing as a result, It is overlapped on first emulsion sheet 11 (being equivalent to " substrate sheets of liquid-permeable sheet ") of body 10 and fixes continuous sheet 20a.Hereafter, it inhales The continuous sheet 20a of acceptor 10 and the first emulsion sheet 11 are integrally conveyed along conveying direction.

This continuous sheet 20a of top flat for example rolls up the shape of 20ar in production line L M with the sheet material rolled along continuous direction Formula is transported.In production line L M, sheet material volume 20ar by exportable is supported in output device 50.Then, it is rolled up from sheet material The continuous sheet 20a of the top flat of the output position P20ar outputs of 20ar is using continuous direction as conveying direction in conveying appropriate It is conveyed towards the above-mentioned position Pj20a that converges on path.Here, when continuous sheet 20a is by being arranged on the transport path Antiseptic coating position P53 when, antiseptic is applied on continuous sheet 20a.That is, matching near coating position P53 It is equipped with antiseptic applying device 53.When continuous sheet 20a is by position P53, the antimicrobial fluid is as antiseptic from the dress Set the 53 non-skin sides for being ejected into sheet material 20a.

As described above, antiseptic when coating is liquid.Therefore, the antiseptic of coating for example passes through continuous sheet 20a's Fiber and spread on the thickness direction of sheet material 20a.Not only in the non-skin side of sheet material 20a, there are antiseptics as a result, and And in the middle position of thickness direction or compared with more by the position of skin side, there is also antiseptics.

In addition, as understood with reference to Fig. 6, the painting of the antiseptic on the transport path of the continuous sheet 20a of top flat The output position P20ar that position P53 is applied than sheet material volume 20ar converges position Pj20a closer to described.Therefore, it is possible to reducing until The delivered length of continuous sheet 20a after fresh or frozen converged until the Pj20a of position.As a result, it is possible to be effectively prevented life Various device (not shown) in producing line LM due to the contact of the antiseptic on the continuous sheet 20a coated in top flat and by Pollution.

Then, the continuous sheet 20a of antiseptic is coated with by being arranged in the conveying direction downstream of the coating position P53 The coating position P55 of the hot-melt adhesive HMA of side.In the process, hot-melt adhesive HMA is by being arranged near P55 in the position Bonding agent coating unit 55 coated in sheet material 20a non-skin side on.At this point, bonding agent HMA with predetermined pattern for example Candy strip is coated.Therefore, as shown in fig. 7, in the antiseptic coating as region of the non-skin side coated with antiseptic Region AR (identical as the domain of the existence AR), forms that there are the bonding agents of bonding agent HMA there are part PHMA and does not deposit In the bonding agent of bonding agent HMA, non-there are part PHMAN.This antiseptic pair first for being related to the continuous sheet 20a of top flat covers The metastatic of piece 11.This will be described later.

Moreover, the continuous sheet 20a of the top flat in this way coated with antiseptic and bonding agent HMA is converging position as described above The transport path for setting Pj20a and absorber 10 converges.Continuous sheet 20a is fixed to the first emulsion sheet of absorber 10 in this way 11。

At this point, as shown in fig. 6, the first emulsion sheet 11 of the non-skin side of the continuous sheet 20a of top flat and absorber 10 Skin side contact.But antiseptic the area of application AR is formed on the non-skin side of continuous sheet 20a, such as Fig. 7 institutes Show, the area of application AR has bonding agent, and there are part PHMA and bonding agent, non-there are part PHMAN.Therefore, it is deposited in bonding agent Inhibit transfer of the antiseptic to the first emulsion sheet 11 at the PHMA of part, and in the case of the bonding agent non-PHMAN there are part, Antiseptic is hardly suppressed to the transfer of the first emulsion sheet 11, and therefore, transfer here can execute in time.Therefore, top flat Continuous sheet 20a and the first emulsion sheet 11 can include reliably antiseptic.

Then, the part for being transferred to the antiseptic of the first emulsion sheet 11 is transferred to absorbent core 10c.In addition, being transferred to A part for the antiseptic of core 10c is transferred to the second emulsion sheet 12 from core 10c.As a result, as described above, this can form top flat 20 (20a), the first emulsion sheet 11, absorbent core 10c and the second emulsion sheet 12 state containing antiseptic.

Herein, from antiseptic in terms of from the continuous sheet 20a of top flat to the metastatic of the first emulsion sheet 11, preferably It is that there are portions than bonding agent in the region AR for the non-ratio there are shared by the PHMAN of part of bonding agent in antiseptic the area of application AR Divide the ratio shared by PHMA big, is both (Fig. 7) in this example.

Converge the magnitude relationship of the fibre density at the Pj20a of position, serialgram of first emulsion sheet 11 than top flat for this Material 20a biggers, absorbent core 10c is than 11 bigger of the first emulsion sheet.Therefore, the capillarity generated based on this magnitude relationship The transfer of antiseptic can also be effectively facilitated.As a result, can be formed in the big model on the thickness direction of sanitary napkin 1 Enclose the interior reliably state containing antiseptic.

On the other hand, in the conveyance direction downstream side for converging position Pj20a, it is configured with embossing device 60.Embossing device 60 include the upper roller and lower roll 60u, 60d of a pair of of rotation.Lower roll 60d therein has peripheral surface, and tool is arranged on the peripheral surface There is the protrusion (not shown) of shape corresponding with the dotted compression unit EMD and threadiness compression unit EML.Therefore, when the company of top flat When continuous sheet material 20a and absorber 10 are by embossing device 60, the continuous sheet 20a and absorber 10 of top flat in a thickness direction from It is compressed by the protrusion on the peripheral surface of lower roll 60d skin side.This results in the compression unit EMD and compression unit EML, by top flat Continuous sheet 20a be more rigidly joined together with absorber 10.At this point, other than these compression units EMD, EML Part is also pushed by the peripheral surface of the peripheral surface of upper roller 60u and lower roll 60d.The pushing (being equivalent to " pressing ") also accelerates described The transfer of antiseptic in a thickness direction.

In the conveyance direction downstream side of the embossing device 60, be set with the continuous sheet 30a of tergite converges position Pj30a, continuous sheet 30a are configured to keep multiple tergites 30,30... continuous along its length.Therefore, there is absorber in integration When the continuous sheet 20a of 10 top flat converges position Pj30a by this, the continuous sheet 30a of tergite is engaged with sheet material 20a. Then, at this point, the continuous sheet 30a of tergite is stressed to be stacked on the continuous sheet 20a of top flat from non-skin, become absorber 10 State between the continuous sheet 20a of top flat and the continuous sheet 30a of tergite, under keeping this state to be transported to and be located at The peripheral sealing device 65 of trip.

Peripheral sealing device 65 includes up-down rollers 65u, 65d of a pair of of rotation.Lower roll 65d therein has peripheral surface, The protrusion (not shown) of shape corresponding with the contour shape of sanitary napkin 1 is provided on the peripheral surface.Therefore, passing through periphery When sealing device 65, the continuous sheet 20a of top flat and the continuous sheet 30a of tergite are for example in the profile with formation sanitary napkin 1 The corresponding position of outer peripheral edge portion 20e, 30e is engaged with each other by modes such as weldings.Then, this generates a sanitary napkin non-individual bodies 1a is consisted of so that multiple sanitary napkins 1,1... are continuous along its length.Non-individual body 1a is sent under conveying direction The die-cutting apparatus 70 of trip.

Die-cutting apparatus 70 includes a pair of of rotating roller 70u, 70d.One of roller 70d has peripheral surface, the periphery mask There is cutter 72, which has shape corresponding with the contour shape of sanitary napkin 1.Therefore, when sanitary napkin non-individual body 1a is logical When crossing the position of die-cutting apparatus 70, sanitary napkin 1 is individually punched from sanitary napkin non-individual body 1a by cutter 72 and monolithic is made Sanitary napkin 1.

From the antiseptic of the continuous sheet 20a coated on top flat to absorber 10 (that is, the first emulsion sheet 11, absorbent core 10c, the second emulsion sheet 12) metastatic from the aspect of, it is preferred that at least converge described in the continuous sheet 20a of top flat Before being contacted with absorber 10 at the Pj20a of position, the antiseptic in sheet material 20a will not all be dried, and be both in this example.

Fig. 8 A and Fig. 8 B are the definition graphs of the sanitary napkin 1 of the first variation of present embodiment.Fig. 8 A are from thickness direction Skin side observation sanitary napkin 1 when diagrammatic top view.Fig. 8 B are the signal exploded views regarded along the arrow B-B direction in Fig. 8 A.

In the described embodiment, as shown in figures 1 and 3, sanitary napkin 1 does not have so-called side in each end of width direction Piece 25,25.But in first variation, sanitary napkin 1 has these lateral plates 25,25.Therefore, main at this point, the One variation is different from the embodiment, in addition to this roughly the same.Therefore, this difference will mainly be described below.With Identical configure of the embodiment is indicated by the same numbers, and by the descriptions thereof are omitted.

In first modification, as shown in Figure 8 A and 8 B, the size in the width direction of top flat 20 is less than the implementation The size of example.That is, although outside of the top flat 20 from absorbent core 10c to width direction is slightly prominent, top flat 20 will not extend To the position of the outer profile of sanitary napkin 1.Therefore, each end in the width direction of the tergite 30 of the outer profile of sanitary napkin 1 is constituted 30ew, 30ew are prominent from top flat 20 to width direction outside.Each end 20ew1,20ew1 in the width direction of the top flat 20 On, lateral plate 25,25 spreads the endlong configuration of length direction, and lateral plate 25,25 is prominent from top flat 20 to width direction outside.Cause This, these lateral plates 25,25 are overlapped on each end 30ew, 30ew of the width direction of tergite 30, bys bonding, welding etc. Engagement.Therefore, the end 30ew of lateral plate 25 and tergite 30 cooperatively forms the outer profile of sanitary napkin 1 each other.

This lateral plate 25 is made of non-woven fabrics, an example as the sheet material made of fiber.As shown in Figure 8 B, lateral plate 25 are overlapped in a manner of the skin side of the end 20ew1 in the width direction for covering top flat 20 with the skin side.So Afterwards, the end 20ew1 of the part 25p of these overlappings and top flat 20 is crimped, thus by 20 integration of these lateral plates 25 and top flat Ground engages.As the trace of this crimping, pressure contact portion E25, E25... (being equivalent to " crimping portion ") formation of multiple rectangles In the part 25p of the overlapping (with reference to Fig. 8 A).

Here, in first variation, it is same as the embodiment, by the central portion of the width direction of top flat 20 20cw1 is set as that there are the domain of the existence AR of antiseptic (with reference to the dot patterns in Fig. 8 A), by the width direction of top flat 20 End 20ew1 is set as the non-domain of the existence ARN there is no antiseptic.Therefore, this restrained effectively the crotch of wearer The impaired situation of skin.Details as Follows.

First, described pressure contact portion E25, E25... on lateral plate 25 have the fibre density (g/ got higher based on the crimping cm³).Therefore, in the production line L M, in the continuous sheet that the continuous sheet (not shown) of lateral plate 25 is crimped on to top flat After 20a is upper, by the non-skin side of continuous sheet 20a of the fluid antimicrobial agent coated in top flat, therefore it is coated in the serialgram Fluid antimicrobial agent on material 20a be easy due to capillarity these pressure contact portions E25 on the continuous sheet of lateral plate 25, E25... it shifts and assembles.On the other hand, due to the skin side of the lateral plate 25 be possible be with the abdomen stock at the crotch of wearer The part of ditch contact, therefore for example damage skin is easy by the skin for the wearer that rubs is especially lateral plate 25.If There are antiseptics on the lateral plate 25, then may increase the damage.

At this point, in first variation, the end 20ew1 of the top flat 20 residing for pressure contact portion E25 is set For there is no the non-domain of the existence ARN of antiseptic.It is therefore prevented that antiseptic is to the flesh being arranged in the end 20ew1 of top flat 20 The transfer of described pressure contact portion E25, E25... of the lateral plate 25 of skin side.As a result, can be effectively prevented from due to antiseptic and make to wear The skin of user is impaired.

Fig. 9 is the definition graph of the sanitary napkin 1 of the second variation of present embodiment, is from the skin side of thickness direction The diagrammatic top view when sanitary napkin 1.

In said embodiment, as shown in figure 5, antiseptic the area of application (domain of the existence) AR is formed as from absorbent core 10c is prominent to width direction outside.In second variation, antiseptic the area of application AR is formed as not from absorbent core 10c It is prominent on the outside of to width direction, that is, be formed as the width direction fit inside with core 10c.

Therefore, in the case of second variation, in the production line L M of Fig. 6 described in converge at the Pj20a of position, push up Antiseptic the area of application AR of the non-skin side of the continuous sheet 20a of piece is in the state that core 10c is substantially covered.That is, should The area of application AR states outstanding on the outside of not from absorbent core 10c to width direction.Therefore, converge position Pj20a at this Downstream side transmitting path on, due to the various devices such as embossing device 60 positioned at the non-skin side of continuous sheet 20a Upper roller 60u and the contact of the non-skin side of sheet material 20a and the problem that corrosion etc. caused by antiseptic may be caused, Neng Goutong Cross the non-skin side of substitution sheet material 20a and by core 10c with the contact of the roller 60u to be effectively avoided.

The difference of second variation and the embodiment essentially consists in the point, essentially identical in addition to this. Therefore, configuration identical with the embodiment is indicated by the same numbers, and by the descriptions thereof are omitted.

From the viewpoint of the anticorrosion of the antiseptic, converge under the Pj20a of position preferably as positioned at shown in fig. 6 The belt conveyer CVa for swimming side uses so-called attraction belt conveyer.Then, pass through the transport road from composition conveyer CVa Multiple inlet holes sucking air (not shown) of the endless belt CVB of diameter, so as to be absorbed simultaneously via the skin side of sheet material 20a Remove the extra antiseptic of the continuous sheet 20a of top flat.Therefore, in next transport path, for example, can be effectively Avoid the lower roll 60d due to the various device embossing devices 60 of the skin side of the continuous sheet 20a positioned at top flat and same sheet material The problems such as non-skin side of 20a is corroded caused by being in contact caused by antiseptic.
