Description

Absorbent commodity

Technical field

It is through on the in-leg of wearer the present invention relates to a kind of, for absorbing the absorbent commodity for keeping the liquid such as urine.

Background technology

Previous known absorbent commodity is to be through the in-leg of wearer for the purpose of absorbing the body fluid for keeping drained On.Absorbent commodity is, for example, disposable diaper, diaper and sanitary napkin.In addition, for disposable diaper, it is known that have example The magic tape that rear body is installed is installed on predecessor and worn by such as pants-type diaper that predecessor engages with the left and right sides portion of rear body Adhesive tape type diaper.

Be configured to can absorb a large amount of body fluid in addition, in absorbent commodity having, so as to can also in response to prolonged wear or The excretion person of adult.For example, for this absorbent commodity, it is known that have nurse used high-selenium corn amount urine not It is wet.The diaper of high-selenium corn amount is typically inserted into the disposable diaper of adhesive tape type or pants type and uses, suitably handed over after excretion It changes.This diaper generally all has an absorber being made of a large amount of absorbent material to can absorb many body fluid, Bing and Its shape is also enlarged, so as to cover the vast area of wearer's body.

However, as described above, even the diaper of high-selenium corn amount, if dress for a long time, body fluid can leak out sometimes, do The disposable diaper of the dirty adhesive tape type being configured at below or pants type.If, can be the one of absorber that is, long lasting for dress Locate (especially in-leg part) constant absorption body fluid repeatedly.Therefore, if the poor diffusivity of absorber, absorbing load will part Ground becomes larger, and when uptake is saturated, inhaling endless body fluid will flow out from diaper.In this regard, in order to increase under absorber The uptake of crotch point, although also thinking makes the absorbent material increase of in-leg part partly increase the uptake of body fluid, But it is locally increased because the thickness of absorber becomes, and wearing feeling can be deteriorated, worrying comfort reduces.

Then, in order to improve the diffusivity of this high-selenium corn amount large-scale absorber again, it is known that absorbent commodity be A part for thickness direction compressed absorbent and form extruded threads (patent document 1 and patent document 2).Disclosed in patent document 1 Absorber (absorbent core), be the body liquid absorptive of the absorber to substantially needing in-leg etc. or diffusible part impose it is close The Embossing processing of collection imposes other part sparse embossing, these embossings become entire continuous pattern.In addition, patent is literary It is the extruding slot that lattice shape is formed in surface side to offer the absorber disclosed in 2, constitutes the extending direction difference for squeezing slot thus In article length direction and product width direction.In this way, by forming extruded threads on the absorbent body, even locally draining The case where a large amount of body fluid, this body fluid can also be spread along extruded threads, it is possible in the broad spectrum absorber of absorber Liquid, as a result, the diffusivity of absorber can be made to improve.

In addition, in order to improve the diffusivity of large-scale absorber with high-selenium corn amount, it is known that absorbent commodity be formed with Thickness direction runs through the slit (patent document 3 and patent document 4) of absorber.For example, Patent Document 3 discloses for single layer Absorber, form the technology of the slit of Y-shaped.In addition, being disclosed in patent document 4 in the multiple absorptions of thickness direction overlapping Body, Bing form the technology of slit on each absorber.This slit be with：It improves the diffusivity of liquid, improve for dress The adaptability of person's body prevents the solid contents such as stool from contacting the skin of wearer for a long time and in order to be easy that absorber is made to be bent Deng various purposes and be formed on absorber.

Invention content

Invent the project to be solved

(the first project)

Such as patent document 1 and it is disclosed Patent Document 2 be formed with the absorber of extruded threads in terms of, be formed with extruded threads Part diffusivity and the diffusible difference in the region (nonextruding region) for not forming extruded threads it is very big.Because diffusible thus Difference absorbs this phenomenon having some setbacks though will produce body fluid and widely spread along extruded threads by nonextruding region, and body fluid can edge It extruded threads and reaches the end of absorber, and have the problem of being leaked out from its end.

It more specifically describes, in the absorber for being formed with extruded threads, when body fluid is absorbed by absorber, utilizes capillary Phenomenon, body fluid can first be spread in time along extruded threads, and then in nonextruding regional diffusion.In this way, being squeezed being formed with There are the time difference in the position of line and nonextruding region, the diffusion time of body fluid.When the base weight of the absorbent material of composition absorber is relatively low, The time difference of above-mentioned diffusion time less becomes great problem, but improves absorbent material if the uptake for increasing body fluid Base weight, then the soak time in nonextruding region can become slower.Therefore, in terms of the absorber of high-selenium corn amount, the diffusion of body fluid The time difference of time can more become larger at the position for being formed with extruded threads and nonextruding region, according to circumstances, it is also possible to will produce only There are extruded threads to be bedewed by body fluid, and almost can not this state of affairs of absorber liquid in nonextruding region.Furthermore it is formed with extruded threads Position is since absorbent material is compressed, so compared to nonextruding region, the uptake of body fluid is less.Therefore, a large amount of body Liquid may escape to outside because that can reach the end of absorber along extruded threads.

In addition, to solve the above-mentioned problems, also thinking, which narrows, is formed in the interval of the extruded threads on absorber, and body fluid is made to hold Easily penetrate into the countermeasure in nonextruding region.However, extruded threads are got higher with the rigidity due to absorber around it, if so narrowing crowded Its density is improved at the interval of crimping, and the skin feel of entire absorber will be hardened, and has damage absorbent commodity wearing feeling Problem.

Then, the present invention is in order to make diffusivity improve and shape on the absorbent body when improving the uptake of body fluid In terms of absorbent commodity at extruded threads, even if Lesson One is entitled not to be densely populated extruded threads, body fluid can also be made effective Ground is diffused into nonextruding region, absorbs body fluid in vast range.

(the second project)

As disclosed in patent document 3 and patent document 4, slit is formed on the absorbent body and improves the diffusible situation of liquid, Since body fluid is flowed by this slit, so the diffusivity at the position for being formed with the slit can be improved, but to make diffusion of body fluids It is not easy to entire absorber Bing.In brief, slit can be such that body fluid expands to horizontal direction in the state of wearer's recumbency It dissipates, but in the state that wearer stands, then can not make body fluid to diffusion above vertical direction or up inhales.Therefore, although shape It can accelerate the diffusion velocity of body fluid at slit, but especially just be difficult to make diffusion of body fluids when wearer takes stance Penetrate into entire absorber.

In addition, although also thinking increases the quantity for the slit being formed on absorber to improve diffusivity, if entire Slit is formed on absorber, then bumps can be formed on the surface of absorber, the problem for having comfort impaired.

Then, for the present invention in terms of the absorbent commodity with the absorber for being formed with slit, the second project is to improve The diffusivity of body fluid above to vertical direction can also entire absorber all absorbers when wearer takes stance Liquid.

Solve the technical solution of project

(the solution technical solution of the first project)

Hereinafter, referring to figs. 1 to Figure 12, the construction of the invention (the first invention) for solving above-mentioned first project is said It is bright.

(1. the 1st implementation form)

Referring to figs. 1 to Fig. 5, just the absorbent commodity about the 1st implementation form of the first invention illustrates.About the 1st The absorbent commodity of implementation form is to be configured to large-scale diaper.Fig. 1 is the vertical view of entire absorbent commodity 100, and Fig. 2 is It is shown schematically as the section shape of II-II lines shown in FIG. 1.Furthermore in terms of the sectional view of Fig. 2, in order to be readily apparent that show Show the construction of absorbent commodity 100, although gap is arranged between various member of formation and describes, actually in member of formation Between be hardly formed gap.

As shown in Figure 1, absorbent commodity 100 can divide into the predecessor 1 positioned at wearer's abdomen side in length direction, be located at The rear body 2 of wearer back side and the lower crotch 3 between predecessor and rear body.It specifically describes, absorbent commodity 100 exists On it is overlooked, the shape that can behave as calabash shape or hourglass shape is formed.That is, there is absorption in lower crotch 3 in absorbent commodity 100 The most narrow position, that is, necking part of the width of property article 100.On the other hand, the necking part than lower crotch 3 more extends width direction The right lateral position, that is, side wing flap in a left side be present in predecessor 1 and the rear body 2 of absorbent commodity 100.That is, being formed with side wing flap The width of part, predecessor 1 and rear body 2 forms more wider than the necking part of lower crotch 3.In this way, absorbent commodity 100 is formed as Calabash shape (hourglass shape).However, the shape of absorbent commodity 100 can suitably change, for example simple square can also be formed as Shape.

In addition, as shown in Figures 1 and 2, absorbent commodity 100 is substantially with the top flat 10 of liquid permeability, opaque liquid Tergite 20 and multiple absorbers 30,40 between top flat and tergite.In this case specification, with positioned at 10 side of top flat Absorber is " upper layer absorber 30 " (the first absorber), to be " lower layer's absorber 40 " (the positioned at the absorber of 20 side of tergite Two absorbers).As shown in the sectional view of Fig. 2, upper layer absorber 30 is overlapped in its thickness direction with lower layer's absorber 40.In addition, Upper layer absorber 30 is engaged with lower layer absorber 40 using solids such as hot melt solids, in order to avoid the relative offset of the two. Top flat 10 covers the opposite surface side of skin of the absorber 30,40 of institute's lamination, and tergite 20 covers the skin of the absorber 30,40 of institute's lamination The non-opposite surface side of skin.As shown in Figures 1 and 2, around each absorber 30,40, top flat 10 is with tergite 20 by heating then Agent, heat-sealing or ultrasonic sealing etc. are engaged each other.Whereby, each absorber 30,40 becomes by the engagement of top flat 10 and tergite 20 Portion surrounds surrounding person.In addition, being formed with a pair of three-dimensional fold 50 at left and right sides of the width direction of absorbent commodity 100.It is a pair of Three-dimensional fold 50 is the left and right sides setting person in absorber, the function as the leakage preventing wall for preventing leakage of urine.Furthermore absorbability Article 100 can also have the cover plate 60 of the non-forward surface of skin of covering tergite 20.Hereinafter, just constituting absorbent commodity 100 Each component illustrates.

Top flat 10 is the skin for being in direct contact wearer's in-leg, and the body fluid such as urine is made to be penetrated into the sheet of absorber 30,40 Component.Therefore, top flat 10 is constituted with the high liquid permeability material of flexibility.Constitute top flat 10 liquid permeability material be, for example, woven fabric, Non-woven fabrics or porous film.In addition it is also possible to using by the thermoplasticity of such as polypropylene or polyethylene, polyester, nylon etc The fiber of resin carries out after hydrophilicity-imparting treatment and then the person that is made non-woven fabrics.For non-woven fabrics, it is viscous that Breathable nonwoven, point can be enumerated Close non-woven fabrics, spun-bonded non-woven fabrics, melt spraying non-woven fabrics etc..

Tergite 20 is to prevent from penetrating top flat 10 and being escaped to the sheet outside diaper by the body fluid that absorber 30,40 absorbs Component.Therefore, tergite 20 is preferably constituted with opaque liquid material.The opaque liquid material for constituting tergite 20 is, for example, by poly- second The opaque liquid film that olefine resin is constituted.Especially for tergite 20, in order to ensure to ventilate when maintaining opaque liquid Property, it is preferable to use it is formed with the fine porous polyethylene film of multiple 0.1~4 μm of fine holes.

Absorber 30,40 is to absorb the body fluid such as urine, keeps the component of the body fluid absorbed.Absorber 30,40 is configured at Between the top flat 10 of fluidity and the tergite 20 of opaque liquid.Upper layer absorber 30 is with lower layer's absorber 40 preferably to heat then The engagements such as agent, in case the relative position of each other deviates.Each absorber 30,40 is by absorbent material 34,44 and cladding absorbability The core Wrapping sheet 35,45 of material 34,44 is constituted.For absorbent material 34,44, can use for example by coniferous tree or Fluff pulp or high water absorbency polymer (SAP), hydrophily thin slice made of the fibrous materials fragmentation such as broad leaf tree.In addition, just absorbing For property material 34,44, among fluff pulp, high water absorbency polymer or hydrophily thin slice, it can be used alone, it can also Bing is combined with two or more.In general, absorbent material 34,44 is by the person institute that is scattered with high water absorbency polymer in fluff pulp It constitutes.Core Wrapping sheet 35,45 is by covering absorbent material 34,44 to keep the flat member of its shape.With regard to core packet For covering thin slice 35,45, the flat member with liquid permeability is used.Core Wrapping sheet 35,45 can be used for example toilet paper it The thin paper of class or well-known non-woven fabrics.

In addition, in the present invention, upper layer absorber 30 is preferably sized to difference with lower layer's absorber 40.Especially at this In invention, the length and width of upper layer absorber 30 are preferably less than the length and width of lower layer's absorber 40.This situation, upper layer Absorber 30 is to be overlapped centered on the lower crotch 3 of absorbent commodity 100 and be configured at the upper surface of lower layer's absorber 40.Whereby, The uptake of the lower crotch 3 more than the excretion of body fluid can be made to increase.However, the size of upper layer absorber 30 and lower layer's absorber 40 And shape can also be identical.

A pair of of solid fold 50 is the left and right sides setting person in absorber, as the leakage preventing wall for preventing leakage of urine.It is three-dimensional Fold 50 is generally made of lateral plate 51 and one or more elastic telescopic components 52.Lateral plate 51 is width direction in lower crotch 3 Exterior portion engaged with the opposite surface side of the skin of top flat 10 or tergite 20, the inboard portion of width direction engagement Bing is opened.And And one or more elastic telescopic components 52 are fixed on the inside of opened lateral plate 51 with elongation state alongst End.Therefore, elastic telescopic component 52 1 is shunk, and the medial end of lateral plate 51 will be with the convergent force of elastic telescopic component 52 And erect, Bing and elastic telescopic component 52 shrink position formed gauffer (rivel).For lateral plate 51, can be used for example by The nonwoven fabric sheet that the card embossing preparation methods such as (card embossed) or spunbond obtain, is particularly preferably using water proofing property and leads to The nonwoven fabric sheet of gas high SMS or SMMS etc..

Cover plate 60 is reinforcement tergite 20 and improves the component of its feel.The non-opposite surface side of skin of cover plate 60 and tergite 20 Fitting.For constituting the material of cover plate 60, woven fabric or non-woven fabrics are used.Especially as the material for constituting cover plate 60, preferably For the non-woven fabrics or Wet-laid non-woven fabric for using the thermoplastic resin by polyethylene, polypropylene, polyester etc to constitute.

As shown in Figures 1 and 2, the absorbent commodity 100 about the present invention, one of feature are following points：In each suction The a plurality of extruded threads 31,41 for making the absorber 30,40 recessed thickness directions are formed on acceptor 30,40.That is, extruded threads 31,41 It is formed on each absorber of the upper layer absorber 30 with lower layer absorber 40 a plurality of.Extruded threads 31,41 can be by from skin phase Each absorber 30,40 is partly squeezed into compression to the both sides or either side of surface side and the non-opposite surface side of skin and is formed.Therefore, At the position for being formed with extruded threads 31,41, the density of the absorbent material 34,44 of each absorber 30,40 can improve.Moreover, shape At on upper layer absorber 30 extruded threads 31 and the extruded threads 41 that are formed on lower layer's absorber 40 in terms of in-plane when, shape At the pattern to cross one another at least partly.Hereinafter, pattern and the formation of the extruded threads 31 being formed on upper layer absorber 30 In the pattern of the extruded threads 41 on lower layer's absorber 40, it is described in detail.

Fig. 3 (a) and be (b) that upper layer absorber 30 is conceptually detached into the transversely arranged displays of Bing with lower layer absorber 40 Vertical view.In addition, Fig. 3 (c) and (d) be shown schematically as III-III lines each absorber 30,40 section shape.In addition, Fig. 4 (a) is the state for showing overlapping upper layer absorber 30 and lower layer's absorber 40, and Fig. 4 (b) is to be shown schematically as IV-IV lines The section shape of absorber.Furthermore the pattern and formation that Fig. 5 is the extruded threads 31 that amplification display is formed on upper layer absorber 30 In the figure of the pattern of the extruded threads 41 on lower layer's absorber 40.

As shown in Figures 3 to 5, extruded threads 31 are formed in the pattern of rectangular clathrate on upper layer absorber 30.This place " pattern of rectangular clathrate " of meaning refers to a plurality of extruded threads that are extended in parallel with length direction with and width direction extend in parallel A plurality of extruded threads intersect, and the pattern in the nonextruding region of zoning square shape.Especially in this embodiment, extruded threads The 31 pattern formation on upper layer absorber 30 is squeezed crimping 31 and surrounds the nonextruding region 32 in four directions all as square Regular pattern (pattern of square lattice shape).It, can be thought of as being formed with a plurality of extruded threads in this way, at the aspect of upper layer absorber 30 31, it is squeezed the intersection point portion that crimping 31 surrounds the nonextruding region 32 of surrounding and extruded threads 31 intersect.Hereinafter, rising for convenience See, the extruded threads 31 for deserving to be called layer absorber 30 are " upside extruded threads 31 ", and nonextruding region 32 is referred to as " the nonextruding region in upside 32 ", intersection point portion 33 is referred to as " upside intersection point portion 33 ".

On the other hand, extruded threads 41 are formed in the pattern of rhomboid clathrate on lower layer's absorber 40.So-called herein " The pattern of rhomboid clathrate " refers to a plurality of extruded threads friendship extended for length direction and the inclined direction of width direction Fork, and the pattern in the nonextruding region of zoning rhomboid (diamond shape).Especially in this embodiment, extruded threads 41 are inhaled in lower layer Pattern formation on acceptor 40 is squeezed crimping 41 and surrounds the nonextruding region 42 in four directions all as positive rhomboid (positive diamond shape) Regular pattern (pattern of positive rhomboid clathrate).In this way, at 40 aspect of lower layer's absorber, it can also be a plurality of crowded thought of as being formed with Crimping 41 is squeezed the intersection point portion that crimping 41 surrounds the nonextruding region 42 of surrounding and extruded threads 41 intersect.Hereinafter, for side Just for the sake of, the extruded threads 41 of lower layer's absorber 40 are referred to as " downside extruded threads 41 ", and nonextruding region 42 is referred to as " the nonextruding area in downside Domain 42 ", intersection point portion 43 are referred to as " downside intersection point portion 43 ".

In addition, in this embodiment, upside extruded threads 31 are by making upper layer absorber 30 from skin forward surface side pressure It is formed under puncture.Similarly, downside extruded threads 41 are by keeping lower layer's absorber 40 concave from skin forward surface side compression It is formed.Therefore, the position of downside extruded threads 41 is formed on lower layer's absorber 40, absorber 30 is absorbed with lower layer on overlapping upper layer The state of body 40 can form gap therebetween.

Fig. 4 and Fig. 5 is the pattern for the upside extruded threads 31 for showing overlapping square lattice shape and positive rhomboid clathrate The state of the pattern of downside extruded threads 41.It is such as learnt by each figure, in this embodiment, the area in the nonextruding region in upside 32 is big Area in the nonextruding region in downside 42.Therefore, in overlapping upper layer absorber 30 and lower layer's absorber 40, the nonextruding area in downside Domain 42 (positive rhomboid), which becomes, to be accommodated in the range of the nonextruding region 32 (square) in upside.

In addition, in this embodiment, delimiting four downsides intersection point portion of certain nonextruding region 42 (positive rhomboid) in downside The 43 upside extruded threads 31 respectively with four sides for delimiting certain nonextruding region 32 (square) in upside overlap.Therefore, such as Fig. 4 and figure Shown in 5, learn that the nonextruding region 42 (positive rhomboid) in downside is accommodated in the range of the nonextruding region 32 (square) in upside just In.That is, the center (cornerwise intersection point) of the nonextruding region 32 (square) in upside and nonextruding 42 (the positive rectangle of region in downside Shape) center (cornerwise intersection point) it is consistent.Furthermore as shown in figure 3, the length direction of the nonextruding region 32 (square) in upside Length L and length direction along the nonextruding region 42 (positive rhomboid) in downside the slightly equal (L=of cornerwise length D1 D1).In addition, the length B of the width direction of the nonextruding region 32 (square) in upside and the width along the nonextruding region in downside 42 Spend cornerwise length D2 slightly equal (B=D2) in direction.Furthermore so-called " summary " in this case specification, refers to allowing ± 5% Error.By meeting these conditions, delimit four downsides intersection point portion 43 of certain nonextruding region 42 (positive rhomboid) in downside at It overlaps for the upside extruded threads 31 respectively with four sides for delimiting the nonextruding region 32 (square) in upside.

In addition, as shown in Figures 4 and 5, upside intersection point portion 33 respectively in the nonextruding region 42 (positive rhomboid) in downside The heart (cornerwise intersection point) overlaps.If seeing it with another visual angle, in multiple downsides, nonextruding region 42 (positive rhomboid) exists 33 overlapping person of upside intersection point portion and 33 not overlapping person of upside intersection point portion.In Fig. 4 and example shown in fig. 5, learns that downside is non-and squeeze Among the multirow of intermediate pressure section 42, in every line, the row that upside intersection point portion 33 overlaps replaces with 33 nonoverlapping row of upside intersection point portion It arranges.Similarly, among the multiple row for learning the nonextruding region in downside 42, every a row, the row that upside intersection point portion 33 overlaps with The nonoverlapping row in upside intersection point portion 33 are alternately arranged.

As described above, the pattern of pattern (the square lattice shape) and downside extruded threads 41 by forming upside extruded threads 31 (positive rhomboid clathrate), even if not being densely populated extruded threads on an absorber, can also be such that body fluid effectively spreads To nonextruding region, body fluid is absorbed in the broad spectrum of two layers of entire absorber.That is, the upside along upper layer absorber 30 is squeezed The body fluid that crimping 31 is spread can be absorbed by the nonextruding region in the downside of lower layer's absorber 40 42.Therefore, along upper layer absorber 30 The body fluid that spreads of upside extruded threads 31 be difficult to reach end, can be effectively prevented and escape to the external state of affairs.Further, since Body fluid can be absorbed in the broad spectrum of two layers of absorber 30,40, so the uptake of body fluid improves, Bing and even if long-time Wear, be not easy to give wearer's unplessantness displeasure.33,43 aspect of intersection point portion on being formed in each absorber 30,40, due to squeezing Crimping 31,41 intersects, so body fluid becomes easy delay.Then, by by the upside intersection point portion 33 of upper layer absorber 30 under The nonextruding region 42 in downside of layer absorber 40 overlaps, and the body fluid for being stranded in upside intersection point portion 33 can be made effectively to penetrate into downside Nonextruding region 42.

In addition, such as this implementation form, by make the rows and columns in the nonextruding region in downside that upside intersection point portion 33 overlaps 42 at For that in every line and every a row, can make to penetrate into the diffusion of body fluids of upper layer absorber 30 to farther region.Therefore, can make to ooze To the diffusion of body fluids of upper layer absorber 30 and penetrate into the broad spectrum of lower layer's absorber 40 thoroughly.

In addition, extruded threads have following function：So that liquid is flowed as slot and make liquid along extruding using capillarity Portion is diffused into the nonextruding region on press section periphery.Even if its function not as slot form come the case where use if can produce The extruded threads of absorber of the raw liquid from the extruded threads of the absorber on one side toward another side or the extradition in nonextruding region.Its reason It is as follows.In brief, extruded threads are the absorbent material deformation persons for making composition absorber with pressure.Therefore, absorber one is in shape At the site absorption liquid for having extruded threads, thickness will change.That is, the paper pulp or SAP mono- in extruded threads absorb, between paper pulp between Every will through when and relax, Bing and SAP can be swollen, so extruded threads can gradually become shallower as, non-after final thickness meeting and swelling squeezes Intermediate pressure section is slightly identical.In this way, even if extruded threads have depth before it is absorbed, carried out with absorbing, depth can also gradually become shallower as.Cause This, be easy from the extruded threads of the absorber on one side to set on extruded threads on the absorber of its another side to overlap or nonextruding Extradite liquid in region.That is, since extruded threads are in initial state formation slot, so liquid can preferentially flow into this extruded threads.Then, The position one for being formed with extruded threads is absorbed, and extruded threads will be swollen, so as previously mentioned, liquid past can be set to and swelling Extruded threads on the absorber for the another side that extruded threads overlap or the movement of nonextruding region.

Herein, the concrete numerical value just about absorbent commodity inscape illustrates.For example, each absorber 30,40 The thickness of thickness, i.e. nonextruding region 32,42 is preferably 5mm~20mm, is particularly preferably 8mm~15mm.In addition, being formed It is preferably 1mm~10mm to have the thickness of each absorber 30,40 at the position of extruded threads 31,41, is particularly preferably 2mm~5mm. However, the thickness for being formed with the position of extruded threads 31,41 is less than the thickness in nonextruding region 32,42 certainly.For example, being formed with crowded The thickness at the position of crimping 31,41 is 3%~50% relative to the thickness in nonextruding region 32,42, it is particularly preferably 5%~ 20%.

In addition, the width of each extruded threads 31,41 is preferably 1mm~5mm, it is particularly preferably 2mm~4mm.In addition, Fig. 2 Shown in the length L in the nonextruding region in upside 32 be preferably 10mm~50mm, be particularly preferably 20mm~40mm or 30mm.On The preferred numberical range of the width B in the nonextruding region in side 32 and the length L are same.Length L and width B preferably omits phase Deng, but can also be different.That is, the shape in the nonextruding region in upside 32 is not limited to square, can also be other quadrangles.This Outside, cornerwise length D1 of nonextruding 42 length direction of region in downside shown in Fig. 2 is preferably 10mm~50mm, especially excellent It is selected as 20mm~40mm or 30mm.The preferred numberical range of cornerwise length D2 of nonextruding 42 width direction of region in downside It is same with the length D1.Length D1 and length D2 is preferably slightly equal, but be can also be different.That is, the nonextruding region in downside 42 shape is not limited to positive rhomboid (positive diamond shape), can also be other rhomboids.Although in addition, as previously mentioned, length L with Length D1 is slightly equal, width B slightly equal with length D2 is preferred implementation form, but Bing of the present invention is not limited by this.

In addition, being widely diffused predecessor and rear body in order to which the body fluid near lower crotch can be will drain to, it is formed in each suction Extruded threads 31,41 on acceptor 30,40 are preferably formed in vast range throughout length direction.Specifically, being formed with crowded Length of the length of the length direction in the region of crimping 31,41 relative to the length direction of each absorber 30,40, preferably 60% More than, it is particularly preferably 60%~100%, 70%~100% or 80%~100%.In addition, in order to which width can be will drain to The body fluid of the immediate vicinity in direction is widely diffused on the outside of width direction, be formed in extruded threads 31 on each absorber 30,40, 41 are preferably formed in vast range throughout width direction.Specifically, being formed with the width side in the region of extruded threads 31,41 To maximum width relative to each absorber 30,40 width direction minimum width, preferably 60% or more, particularly preferably It is 60%~100%, 70%~100% or 80%~100%.

Furthermore it in this embodiment, illustrates with the figure of the bigger square lattice shape of the area in nonextruding region Case forms upside extruded threads 31, and forming downside with the pattern of the smaller positive rhomboid clathrate of the area in nonextruding region squeezes The example of line 41.However, the pattern of this extruded threads can also be exchanged in upside extruded threads 31 and downside extruded threads 41.That is, also may be used Pattern to be applicable in the square lattice shape is applicable in the pattern of positive rhomboid clathrate as the pattern of downside extruded threads 41 Pattern as upside extruded threads 31.

In addition, showing extruded threads 31,41 by making the absorbent material 34,44 of each absorber of composition 30,40 in figure And core Wrapping sheet 35,45 the two it is concave and formed example.However, extruded threads 31,41 are by least making absorbability material 34, the 44 concave and former of compression of material.That is, can in compression absorbent material 34,44 and after forming extruded threads 31,41, Core Wrapping sheet 35,45 is bonded into and coats its absorbent material 34,44.In this sense, extruded threads 31,41 are formed in composition It is just much of that on the absorbent material 34,44 of each absorber 30,40.

(2. the 2nd implementation form)

Then, with reference to Fig. 6 to Fig. 8, just the absorbent commodity about the 2nd implementation form of the first invention illustrates.It closes In the 2nd implementation form, construction identical with the 1st implementation form is omitted the description, with different with the 1st implementation form It is illustrated centered on construction.

Fig. 6 (a) and be (b) that separation shows upper layer absorber 30 and lower layer's absorber 40, Fig. 6 (c) and be (d) display VI- The section shape of VI.Fig. 7 (a) is the state for showing overlapping upper layer absorber 30 and lower layer's absorber 40, and Fig. 7 (b) is display The section shape of VII-VII.In addition, Fig. 8 is the pattern and shape that amplification display is formed in the extruded threads 31 on upper layer absorber 30 At the figure of the pattern in the extruded threads 41 on lower layer's absorber 40.Furthermore in Fig. 6 and Fig. 7, conceptually only capture in display Layer absorber 30 and lower layer's absorber 40.In Fig. 6 and Fig. 7, although not shown, but the 2nd implementation form described herein as Also same with the 1st implementation form, at least have top flat 10 and tergite 20, a pair of three-dimensional fold can also be further equipped with 50 and cover plate 60.

2nd implementation form be formed at the extruded threads 31,41 on each absorber 30,40 pattern and the 1st implementation form not Together.As shown in Figure 6 to 8, upside extruded threads 31 are formed with the pattern of positive rhomboid clathrate on upper layer absorber 30, Downside extruded threads 41 are formed with the pattern of square lattice shape on lower layer's absorber 40.So-called positive rhomboid clathrate herein Pattern illustrate with the pattern of square lattice shape and in the 1st implementation form it is substantially the same.However, implementing shape the 2nd In terms of state, the state of absorber 30 and lower layer's absorber 40 on overlapping upper layer, the positive rhomboid being formed on upper layer absorber 30 The relative position relation of the pattern of the pattern of clathrate and the square lattice shape being formed on lower layer's absorber 40 is but real with the 1st Apply form difference.

As shown in Figures 7 and 8, in the 2nd implementation form, in the state of each absorber 30,40 that overlaps, upper layer absorber 30 The downside intersection point portion 43 of upside intersection point portion 33 and lower layer's absorber 40 overlap.Furthermore in multiple upsides of upper layer absorber 30 Among intersection point portion 33, there is center (cornerwise intersection point) overlapping person with the nonextruding region in the downside of lower layer absorber 40 42. Especially in the pattern weight of the downside extruded threads 41 of the pattern and lower layer's absorber 40 of the upside extruded threads 31 of upper layer absorber 30 In range repeatedly, upside intersection point portion 33 is present in the range in the nonextruding region in all downsides 42.Therefore, in the 2nd implementation form In, learn that upside extruded threads 31 and being equivalent to form cornerwise position in the nonextruding region in downside 42 of square shape and overlap. Furthermore in the 2nd implementation form, learn that downside extruded threads 41 overlap in the range in the nonextruding region in upside 32.

In this way, in the 2nd implementation form, downside extruded threads 41 overlap in the range in the nonextruding region in upside 32, and upside is squeezed Crimping 31 and upside intersection point portion 33 overlap in the range in the nonextruding region in downside 42, Bing and upside intersection point portion 33 and downside intersection point portion 43 overlap.Therefore, the body fluid spread along the upside extruded threads 31 of upper layer absorber 30 can be fallen on lower layer's absorber 40, by under The nonextruding region 42 in side absorbs.In addition, the body fluid for being stranded in the upside intersection point portion 33 of upper layer absorber 30 can fall on lower layer's absorption On body 40, spread along downside extruded threads 41 by downside intersection point portion 43.Furthermore it is squeezed along the downside of lower layer's absorber 40 The body fluid that line 41 is spread can be absorbed by the nonextruding region in the upside of upper layer absorber 30 32.In addition, downside extruded threads 41 can also Body fluid is spread to the diagonal of the lattice-shaped pattern of upside extruded threads 31.Whereby, it by forming this pattern, is connected in previous Body fluid can promptly be imported by being considered as the slow nonextruding region 32,42 of soak time.

In this way, pattern of the pattern of the 2nd implementation form compared to the 1st implementation form, it may be said that the infiltration rate of body fluid compared with Soon.In this regard, pattern of the pattern of the 1st implementation form compared to the 2nd implementation form, it may be said that the range of scatter of body fluid is wider.It wants Using that pattern of the pattern of the pattern and the 2nd implementation form of the 1st implementation form, consider to required by absorbent commodity It determines after performance and then suitably.

Furthermore the width, diagonal line about each extruded threads 31,41 are in the length D1 of nonextruding 32 length direction of region in upside Or diagonal line is in the value of the length L or width B of nonextruding 42 length direction of region of the length D2 of width direction or downside, it is excellent It is selected as range same with the 1st implementation form.

(3. the 3rd implementation form)

Then, with reference to Fig. 9 to Figure 10, just the absorbent commodity about the 3rd implementation form of the first invention illustrates.Figure 9 (a) and it is (b) that separation shows upper layer absorber 30 and lower layer's absorber 40, Fig. 9 (c) and the section shape for being (d) display IX-IX Shape.Figure 10 (a) is the state for showing overlapping upper layer absorber 30 and lower layer's absorber 40, and Figure 10 (b) is the section for showing X-X Shape.Fig. 9 and Figure 10 is conceptually only to capture to show upper layer absorber 30 and lower layer's absorber 40.Although not shown, But the 3rd implementation form described herein as is also same with the 1st implementation form, at least has top flat 10 and tergite 20, also may be used To be further equipped with a pair of three-dimensional fold 50 and cover plate 60.

In the 3rd implementation form, a plurality of upside extruded threads for extending length direction are formed on upper layer absorber 30 31.In the example in the figures, upper layer absorber 30 has the central compression line 31a positioned at width direction center, positioned at left Left extruded threads 31b and right extruded threads 31c positioned at right.Each extruded threads 31a, 31b, 31c are logical from the predecessor of upper layer absorber 30 It crosses lower crotch and extends to rear body.Central compression line 31a is entirely alongst to be formed as one linearly.In this regard, left extruding Line 31b and right extruded threads 31c is to be respectively divided into the linear front side straight line portion 31d positioned at 1 side end of predecessor, be located at rear body side The linear rear side straight line portion 31e of end and in lower crotch 3 than on front side of straight line portion 31d and rear side straight line portion 31e be more located at it is wide Spend the linear in-leg straight line portion 31f on the inside of direction.Furthermore left extruded threads 31b and right extruded threads 31c is respectively provided with oblique oblique Connection front side straight line portion 31d is inclined into the front side rake 31g of in-leg straight line portion 31f and oblique squint into straight line on rear side of connecting The rear side rake 31h of portion 31e and in-leg straight line portion 31f.Whereby, between central compression line 31a and left and right extruded threads 31b, 31c To be spaced in predecessor side and rear body side more separated, lower crotch relatively.Since the lower crotch of upper layer absorber 30 is to hold The position for the body fluid drained from the in-leg of wearer is easily contacted, so the interval of the extruded threads 31 by reducing this position, holds Easily body fluid is spread to length direction.Furthermore it in this embodiment, is not formed on upper layer absorber 30 and is extended to width direction Extruded threads.Therefore, in the intersection point portion that extruded threads are not present on upper layer absorber 30.

On the other hand, a plurality of downside extruded threads 41 for extending width direction are formed on lower layer's absorber 40.Scheming In the example shown, on lower layer's absorber 40, it is configured at regular intervals along width in length direction after from predecessor The linear downside extruded threads 41 that direction extends.Furthermore it in this embodiment, is not formed to length on lower layer's absorber 40 Spend the extruded threads that direction extends.Therefore, in the intersection point portion that extruded threads are not present on lower layer's absorber 40.

If above-mentioned upper layer absorber 30 and lower layer's absorber 40 are overlapped in thickness direction, as shown in Figure 10, upper layer The upside extruded threads 31 of absorber 30 and the downside extruded threads 41 of lower layer absorber 40 can intersect.In this way, by making to extend length The a plurality of upside extruded threads 31 and the extruded threads of the absorber for the another side for extending width direction for spending direction intersect, and can make body fluid It spreads to length direction, while also being spread to width direction.Especially body fluid is difficult to spread to length direction, and body fluid is easy End in the width direction leaks out.Therefore, the upside extruded threads 31 for extending length direction are formed on upper layer absorber 30, The downside extruded threads 41 for extending width direction are formed on lower layer's absorber 40.Whereby, can make initially to contact upper layer absorber 30 Body fluid spread to length direction, the body fluid for making to penetrate into lower layer's absorber 40 thereafter is auxiliarily spread to width direction.It is tied Fruit can be such that body fluid is effectively spread to length direction, while can prevent the leakage of end in the width direction.

(example of the section shape of 4. absorbers)

It is to make upper layer absorber 30 and lower layer's absorber 40 with regard to being formed in terms of the implementation form of the 1st, the 2nd and the 3rd The examples of the concave extruded threads 31,41 in the opposite surface side of skin be illustrated.However, Bing of the present invention is not limited by this.Hereinafter, The other example for putting up with the section shape of each absorber illustrates.

Figure 11 is the example for showing upper layer absorber 30 and the section shape of lower layer's absorber 40.Shown in Figure 11 (a) In example, the extruded threads 31 of upper layer absorber 30 are to make the non-opposite concave person in surface side of skin, the extruded threads 41 of lower layer's absorber 40 It is to make the concave person in the opposite surface side of skin.Therefore, upper layer absorber 30 is formed with lower layer absorber 40 on face toward each other Extruded threads 31,41.Thus, at the position for being formed with extruded threads 31,41, it can be in upper layer absorber 30 and lower layer's absorber 40 Between generate gap.Whereby, the body fluid wandered from upper layer absorber 30 to lower layer's absorber 40 can be diffused into lower layer's absorber 40 Broad spectrum.

In the example shown in Figure 11 (b), the extruded threads 31 of upper layer absorber 30 are to keep the opposite surface side of skin and skin non- The concave person of the two of opposite surface side, the extruded threads 41 of lower layer's absorber 40 are only to make the concave person in the opposite surface side of skin.In this way, passing through Keep the opposite surface side of the skin of upper layer absorber 30 and the two of the non-opposite surface side of skin concave, body fluid can be maintained to be inhaled on upper layer on one side Diffusivity on 30 surface of acceptor, on one side by the gap between upper layer absorber 30 and lower layer's absorber 40 ensure more spaces it Gap.Therefore, diffusion of body fluids can be made to the broad spectrum of 40 the two of upper layer absorber 30 and lower layer's absorber.

In the example shown in Figure 11 (c), the extruded threads 31 of upper layer absorber 30 are to keep the opposite surface side of skin and skin non- The extruded threads 41 of the concave person of the two of opposite surface side, Bing and lower layer's absorber 40 are also to keep the opposite surface side of skin non-opposite with skin The concave person of the two of surface side.It is same with example shown in Figure 11 (b) whereby, body fluid can be maintained in 30 table of upper layer absorber on one side Gap between upper layer absorber 30 and lower layer's absorber 40 is ensured the gap in more spaces by the diffusivity on face on one side.This Outside, it by keeping the two of the non-opposite surface side of the opposite surface side of the skin of lower layer's absorber 40 and skin concave, can maintain down on one side Diffusivity on 40 front of layer absorber, further the back side of lower layer's absorber 40 also makes body fluid effectively permeate on one side. That is, the back side in lower layer's absorber 40 is configured with tergite 20 (with reference to Fig. 2).Moreover, by lower layer's absorber 40 and tergite Gap is set between 20, and reaching the body fluid of tergite 20 can further be spread by extruded threads 41 of lower layer's absorber 40, by under The back side of layer absorber 40 absorbs.Whereby, body fluid is absorbed using entire upper layer absorber 30 and lower layer's absorber 40.

In the example shown in Figure 11 (d), the extruded threads 31 of upper layer absorber 30 are to make the concave person in the opposite surface side of skin, under The extruded threads 41 of layer absorber 40 are to make the non-opposite concave person in surface side of skin.Therefore, upper layer absorber 30 and lower layer's absorber 40 Substantially seamlessly engaged.This manner it is also possible to be bonded into not between upper layer absorber 30 and lower layer's absorber 40 between formation Gap.

Figure 12 is to show other than upper layer absorber 30 and lower layer's absorber 40, is also further equipped with additional absorber 70 The example of the absorbent commodity of (third absorber).In the example in figure 12, additional absorber 70 is disposed in upper layer absorber 30 The opposite surface side of skin, i.e., between upper layer absorber 30 and top flat 10 (with reference to Fig. 2).However, additional absorber 70 can also match Set on the non-opposite surface side of the skin of lower layer's absorber 40, i.e., between lower layer's absorber 40 and tergite 20 (with reference to Fig. 2).It is additional to absorb Body 70 is preferably and upper layer absorber 30 is same as lower layer's absorber 40, has a plurality of extruded threads 71.As shown in figure 12, extruded threads 71 can be the concave person in the opposite surface side of skin for making additional absorber 70, can also be to keep the skin of additional absorber 70 non-opposite The concave person in surface side.The pattern of the extruded threads 71 of additional absorber 70 is not particularly limited, and can suitably be useful in the the 1st, the 2nd and the The pattern of extruded threads illustrated in 3 implementation forms.Furthermore although illustration omitted, other than additional absorber 70, also may be used With one or more absorbers that further coincide.

More than, in this case specification, in order to show present disclosure, on one side with reference to attached drawing, carry out this hair on one side The explanation of bright implementation form.However, Bing of the present invention is not limited by above-mentioned implementation form, include to be proficient in this technology person to be based on certainly Item recorded in this case specification and change form apparent easy to know or improvement form.

It is formed in squeezing for the lattice-shaped pattern illustrated in the 1st implementation form and the 2nd implementation form for example, it is also possible to combine Crimping and the extruded threads in the direction for extending length direction or width direction illustrated in the 3rd implementation form.That is, institute Among two absorbers of lamination, can also with the absorber on one side for be squeezed around multiple crimping surrounded it is nonextruding Region person is with a plurality of extruded threads person extended to length direction or width direction with the absorber of another side.For example, not only It can be formed with the extruded threads of rectangular clathrate shown in Fig. 3 (a) on upper layer absorber 30, be formed on lower layer's absorber 40 With a plurality of extruded threads extended along width direction shown in Fig. 9 (b), and can also be that it is opposite.In addition, for example, not only The a plurality of extruded threads alongst to extend shown in Fig. 9 (a) can be formed on upper layer absorber 30, absorbed in lower layer It is formed with the extruded threads of rhomboid clathrate shown in Fig. 3 (b) on body 40, and can also be that it is opposite.

(the second inventions of II.)

Hereinafter, referring to Fig.1 3 to Figure 26, with regard to the construction progress of the invention (the second invention) for solving above-mentioned second project Explanation.About the second invention, the construction common with above-mentioned the first invention is omitted the description, mainly with above-mentioned the first invention not It is illustrated centered on same point.

(1. the 1st implementation form)

Referring to Fig.1 3 to Figure 16, just the absorbent commodity about the 1st implementation form of the second invention illustrate.About The absorbent commodity of 1 implementation form is composed as large-scale diaper.Figure 13 is the vertical view of entire absorbent commodity 100, Figure 14 is the section shape for being shown schematically as XIV-XIV lines shown in Figure 13.Furthermore in terms of the sectional view of Figure 14, in order to hold Show the construction of absorbent commodity 100 with being readily appreciated that, although gap is arranged between various member of formation and describes, actually It is to be hardly formed gap between member of formation.

As shown in figure 13, absorbent commodity 100 can divide into the predecessor 1 positioned at wearer's abdomen side, position in length direction In the rear body 2 of wearer back side and the lower crotch 3 between predecessor and rear body.It specifically describes, absorbent commodity 100 In its vertical view, the shape that can behave as calabash shape or hourglass shape is formed.This point and above-mentioned the first invention are common.

In addition, as shown in FIG. 13 and 14, absorbent commodity 100 substantially top flat 10, opaque liquid with liquid permeability Tergite 20 and multiple absorbers 30,40 between top flat and tergite.In this case specification, to be located at 10 side of top flat Absorber be " upper layer absorber 30 " (the first absorber), with positioned at the absorber of 20 side of tergite be " lower layer's absorber 40 " (the second absorber).As shown in the sectional view of Figure 14, upper layer absorber 30 is overlapped in its thickness direction with lower layer's absorber 40.This Outside, upper layer absorber 30 is engaged with lower layer absorber 40 using solids such as hot melt solids, in case the relative position of the two is inclined It moves.Top flat 10 covers the opposite surface side of skin of the absorber 30,40 of institute's lamination, and tergite 20 covers the absorber 30,40 of institute's lamination The non-opposite surface side of skin.As shown in FIG. 13 and 14, around each absorber 30,40, top flat 10 is hot melt with tergite 20 Solid, heat-sealing or ultrasonic sealing etc. are engaged each other.Whereby, each absorber 30,40 becomes by top flat 10 and tergite 20 Person around engagement portion envelopes.In addition, being formed with a pair of three-dimensional fold 50 at left and right sides of the width direction of absorbent commodity 100. A pair of of solid fold 50 is the left and right sides setting person in absorber, the function as the leakage preventing wall for preventing leakage of urine.Furthermore Absorbent commodity 100 can also have the cover plate 60 of the non-forward surface of skin of covering tergite 20.These absorbent commodities 100 it is each The essential structure of element (10,20,30,40,50,60) and above-mentioned the first invention are common.

Figure 15 (a) and be (b) that upper layer absorber 30 is conceptually detached into the transversely arranged displays of Bing with lower layer absorber 40 Vertical view.In addition, Figure 15 (c) and (d) be shown schematically as XV-XV lines each absorber 30,40 section shape.In addition, Figure 16 (a) is the state for showing overlapping upper layer absorber 30 and lower layer's absorber 40, and Figure 16 (b) is to be shown schematically as XVI-XVI The section shape of the absorber of line.

As shown in figure 13 to figure 16, the slit 36 in thickness direction is formed through on upper layer absorber 30.In this reality It applies in form, slit 36 is to be formed as extending to length direction elongated centered on the lower crotch 3 of absorbent commodity 100 Slightly elliptical shape.In addition, slit 36 is formed as the closed at both ends poroid of length direction.Slit 36 is preferably at least a part of position In the lower crotch 3 of absorbent commodity 100, length direction can also be extended from lower crotch 3 to predecessor 1 and rear body 2.

The length for indicating the length direction of slit 36 in Figure 15 with symbol S1, the length of width direction is indicated with symbol S2 (width).For example, set the length of the length direction of entire upper layer absorber 30 as 100% when, the length S1 of slit 36 is set as 20%~100% or 25%~80%.In addition, for example, the length (width) for setting the width direction of upper layer absorber 30 (has The wide position of width and its minimum value when narrow position) when being 100%, the width S 2 of slit 36 is set as 10%~50% or 15% ~30%.Slit 36 be with the function person that body fluid is imported to lower layer absorber 40, so its width S 2 be preferably 5mm with On.

In addition, in this embodiment, a plurality of extruded threads 31 are formed on upper layer absorber 30.Upper layer absorber 30 A plurality of extruded threads 31 (hereinafter referred to as " upside extruded threads ") can pass through the both sides from the opposite surface side of skin and the non-opposite surface side of skin Or upper layer absorber 30 is partly squeezed compression and is formed by either side.Therefore, be formed with upside extruded threads 31 position, on The density of the absorbent material 34 of layer absorber 30 can improve.In this embodiment, upside extruded threads 31 are by from skin Opposite surface side squeezes upper layer absorber 30 and is formed.

For a plurality of upside extruded threads 31, it is equipped in each side of 1 side of predecessor and 2 side of rear body and is located at width direction center Central compression line 31a, the left extruded threads 31b positioned at left and the right extruded threads 31c positioned at right.In the example in the figures, shape At there is total 6 extruded threads.These a plurality of upside extruded threads 31 have the portion extended to the length direction of upper layer absorber 30 Point.Therefore, the body fluid of contact upper layer absorber 30 can be spread along each upside extruded threads 31 to length direction.More particularly Bright, front and back central compression line 31a, which is respectively formed, alongst extends linear, one end arrival upper layer absorber 30 length direction ora terminalis, the other end reach slit 36.In addition, front and back left extruded threads 31b and right extruded threads 31c includes Straight line portion 37a from the length direction ora terminalis of upper layer absorber 30 to 3 side of lower crotch that extend from and to the interior inclination of width direction Tiltedly extend into the sloping portion 37b of connection this straight line portion 37a and slit 36.

In this way, in this embodiment, a plurality of upside extruded threads 31 are entirely formed to be connected to slit 36.Whereby, by wearing The body fluid of the in-leg excretion for the person of wearing first be imported into slit 36 and after temporarily storing, and then along each upside for being connected to this slit 36 Extruded threads 31 are spread to length direction.In this way, since a plurality of diffused line is collectively formed in slit 36 and upside extruded threads 31, so Entire upper layer absorber 30 can absorb body fluid, and uptake and infiltration rate improve, and can more certainly prevent the leakage of body fluid Go out.In addition, slit 36 is connect with a part for upside extruded threads 31, the body fluid of slit 36 is temporarily lodged in readily along this upside Extruded threads 31 are spread.Body fluid can especially spread from the wall surface inside slit 36 along upside extruded threads 31, so can be improved Diffusivity of the body fluid in upper layer absorber 30.Furthermore it in this embodiment, is not formed to width side on upper layer absorber 30 To the extruded threads of extension.Therefore, in the intersection point portion that extruded threads are not present on upper layer absorber 30.

In addition, being also formed with a plurality of extruded threads 41 on lower layer's absorber 40.The a plurality of extruded threads 41 of lower layer's absorber 40 (hereinafter referred to as " downside extruded threads ") can by from the both sides of the opposite surface side of skin and the non-opposite surface side of skin or either side will under Layer absorber 40 partly squeezes compression and is formed.Therefore, be formed with downside extruded threads 41 position, lower layer's absorber 40 The density of absorbent material 44 can improve.In this embodiment, downside extruded threads 41 are by being squeezed from the opposite surface side of skin Lower layer's absorber 40 and formed.

In this embodiment, a plurality of extruded threads 41 of lower layer's absorber 40 are respectively formed as along absorbent commodity 100 Width direction extend.In the example in the figures, on lower layer's absorber 40, from predecessor after in length direction with rule Interval is configured with the linear downside extruded threads 41 extended along width direction.Furthermore it in this embodiment, is inhaled in lower layer The extruded threads extended to length direction are not formed on acceptor 40.Therefore, the intersection point portion of extruded threads is not present in lower layer's absorber 40 On.

In addition, in fig.15, the length (width) of the width direction of downside extruded threads 41 is indicated with symbol W.Downside squeezes Line 41 is for making the body fluid of contact lower layer absorber 40 to the vast diffusion person of the width direction of lower layer's absorber 40.Therefore, if The length (width) (position for having width wide and its minimum value when narrow position) of the width direction of lower layer's absorber 40 is 100% When, the width W of downside extruded threads 41 is preferably formed with 50%~100% or 70%~95%.In addition, downside extruded threads 41 Width W is preferably more than the width S 2 (W ＞ S2) of the slit 36 of upper layer absorber 30.Specifically, the width of downside extruded threads 41 It is preferably the width S 2 for slit 36 to spend W, is 110% or more, 150% or more, 200% or more or 250% or more.Downside is squeezed The width W of crimping 41 is not particularly limited relative to the upper limit value of the value of the width S 2 of slit 36, is set as such as 10 times of degree .

Figure 16 is that display above-mentioned upper layer absorber 30 and lower layer's absorber 40 coincide in the state of thickness direction.Such as Figure 16 Shown, the downside extruded threads 41 of lower layer's absorber 40 overlap with the slit 36 of upper layer absorber 30.Therefore, body fluid one is imported into The slit 36 of layer absorber 30 will be wandered by slit 36 to lower section, the downside extruded threads 41 of contact lower layer absorber 40. Then, the body fluid of contact lower layer absorber 40 is spread along downside extruded threads 41 to width direction.Especially in this implementation form In, as previously mentioned, the width W of downside extruded threads 41 is more than the width S 2 of slit 36.Therefore, lower layer is contacted by slit 36 to inhale The body fluid of acceptor 40 can along downside extruded threads 41 to outside width direction side diffusion, into upper layer absorber 30 and lower layer's absorber 40 gap.Whereby, connecting the back side (the non-opposite surface side of skin) of layer absorber 30 can also make it absorb body fluid.Therefore, Body fluid, Bing and the raising of its uptake can promptly be absorbed.

Furthermore the slit 36 of upper layer absorber 30 is when for example wearer takes stance, not by body fluid from in-leg The ability that portion 3 is vertically drunk up to 1 side of predecessor or 2 side of rear body, but upside extruded threads 31 or downside extruded threads 41 have body fluid The ability vertically drunk up.Therefore, by the way that upside extruded threads 31 to be connected to the slit 36 of upper layer absorber 30 or squeeze downside Crimping 41 is set to the lower section of slit 36, can by the body fluid for temporarily lodging in slit 36 to drinking up above vertical direction, make its to The vast diffusion in 1 side of predecessor and 2 side of rear body.

Herein, in order to understand the technology of the present invention, the principle that body fluid is absorbed by extruded threads is specifically described.Work as absorber When liquid, absorber can occur simultaneously body fluid by the slot of extruded threads expand flowing the first diffusion phenomena and because extruded threads week Higher than the density other than extruded threads capillarity occurs for the density on side, and the second diffusion that liquid can be spread along extruded threads is existing The two of elephant.First diffusion phenomena are dynamic diffusion, although the diffusion velocity in plane is fast, can not be expected body fluid to hanging down Histogram is to the effect drunk up.On the other hand, due to the second diffusion phenomena of the capillarity around extruded threads, although expanding Scattered amount of liquid is fewer than the first diffusion phenomena, but it can be expected that the effect that body fluid is vertically drunk up along extruded threads and is spread. In this way, the extruded threads being formed on absorber have the ability for drinking up body fluid to vertical direction top.Furthermore it is so-called herein The situation for vertically sucting body fluid is equivalent to and in stance drinks up the urine for lodging in in-leg etc to predecessor and rear body Situation.

In addition, open greatly diaper the case where, the overall length of absorber is longer, and the distance from vented position to edge is longer. If only urination part will urine partly sop up, cannot use entire absorber, can thus generate urination repeatedly and cause Leakage of urine.Therefore, the diaper opened greatly, which is required to use absorber to edge, absorbs a greater amount of urine.However, the urine opened greatly The not wet gross absorption that is more than is more, and it is fast to be also required to infiltration rate.Being intended to enable a wearer to after urination can be fast Comfortable wear sense is obtained fastly.In addition, general thicker absorber is to overlap two layers or more absorber and make, this feelings mostly Condition, in order to accelerate infiltration rate, and the technology that slit is arranged on the absorber of upper layer is known.In addition, lower layer's absorber also exists Slit is set on position identical with upper layer absorber, it is known to further increase diffusible technology also.However, this slit Although making the channel of body fluid flowing or playing the effect that body fluid is temporarily stored in its slit etc. makes in the place to go of flowing The effect of diffusion of body fluids is but very low.Then, in terms of the present invention, slit 36 is formed to carry on upper layer absorber 30 by one side The diffusion velocity or water of high body fluid, on one side on lower layer's absorber 40 formed on the downside of extruded threads 41 with promote body fluid utilize capillary The diffusion of pipe phenomenon makes body fluid pervious to the broad spectrum of each absorber 30,40.

In this way, the present invention utilizes the slit 36 of upper layer absorber 30 and both downside extruded threads 41 of lower layer's absorber 40 Advantage improves diffusion velocity, diffusing capacity and the range of scatter of body fluid.Therefore, it is at least inhaled with upper layer among lower layer's absorber 40 The ranging preferably from for the overlapping of slit 36 of acceptor 30 does not form slit.In the position with the overlapping of the slit 36 of upper layer absorber 30, Ruo Lian lower layers absorber 40 also forms slit, then the downside extruded threads 41 that may can not effectively utilize lower layer's absorber 40 expand The effect of granular media liquid.However, Bing of the present invention is not the form for excluding to be formed slit on lower layer's absorber 40.

Furthermore as shown in figure 16, in the state of overlapping upper layer absorber 30 and lower layer's absorber 40, upside extruded threads 31 with Downside extruded threads 41 intersect at least partly in terms of in-plane.Furthermore so-called " in terms of in-plane ", refer to from top flat 10 or the opposite direction of tergite 20 see.In this way, being reported to the leadship after accomplishing a task by the way that each absorber 30,40 is configured to mutual extruded threads 31,41, even Not forming the region (nonextruding region) of extruded threads can also be such that body fluid effectively permeates.That is, along one side absorber squeeze The body fluid of crimping diffusion is easy to be absorbed by the nonextruding region of the absorber of another side.Therefore, squeezing along the absorber on one side The body fluid of crimping diffusion is difficult to reach end, can be effectively prevented and escape to the external state of affairs.Further, since can be in two layers of suction The broad spectrum of acceptor 30,40 absorbs body fluid, so the uptake of body fluid improves, Bing and even if prolonged wear, it is also difficult to Give wearer's unplessantness displeasure.Furthermore by forming extruded threads 31,41 on each absorber of two layers of absorber 30,40, with regard to nothing It need to be densely populated extruded threads on each absorber.Therefore, the skin feel that can avoid each absorber is hardened.

Herein, the thickness of the thickness of each absorber 30,40, i.e., nonextruding region is such as preferably 5mm~20mm, especially It is preferably 8mm~15mm.In addition, the thickness in each absorber 30,40 for being formed with the position of extruded threads 31,41 is preferably 1mm~10mm is particularly preferably 2mm~5mm.However, the thickness for being formed with the position of extruded threads 31,41 certainly is less than non-squeeze The thickness of intermediate pressure section.For example, be formed with thickness of the thickness at the position of extruded threads 31,41 relative to nonextruding region, be 3%~ 50%, it is particularly preferably 5%~20%.In addition, the width of each extruded threads 31,41 is preferably 1mm~5mm, particularly preferably For 2mm~4mm.

Furthermore show extruded threads 31,41 by making the absorbent material of each absorber of composition 30,40 in the figure of this case 34,44 and core Wrapping sheet 35,45 the two it is concave and formed example.However, extruded threads 31,41 are by least making absorbability The compression of material 34,44 is concave and is formed.That is, can in compression absorbent material 34,44 and after forming extruded threads 31,41, Core Wrapping sheet 35,45 is engaged to coat its absorbent material 34,44.In this sense, extruded threads 31,41 are formed in composition On the absorbent material 34,44 of each absorber 30,40.

(2. the 2nd implementation form)

Then, referring to Fig.1 7 to Figure 19, just the absorbent commodity about the 2nd implementation form of the second invention illustrate. About the 2nd implementation form, construction identical with the 1st implementation form is omitted the description, with different with the 1st implementation form Construction centered on and illustrate.

Figure 17 (a) and be (b) that upper layer absorber 30 is conceptually detached into the transversely arranged displays of Bing with lower layer absorber 40 Vertical view.In addition, Figure 17 (c) and (d) be shown schematically as V-V lines each absorber 30,40 section shape.In addition, figure 18 (a) is the state for showing overlapping upper layer absorber 30 and lower layer's absorber 40, and Figure 18 (b) is to be shown schematically as line VI -- VI The section shape of absorber.Furthermore Figure 19 is the pattern and shape that amplification display is formed in the extruded threads 31 on upper layer absorber 30 At the figure of the pattern in the extruded threads 41 on lower layer's absorber 40.Furthermore in Figure 17 and Figure 18, display is conceptually only captured Upper layer absorber 30 and lower layer's absorber 40.Although the illustration omitted in Figure 17 and Figure 18, the 2nd implementation form described herein as Also same with the 1st implementation form, at least have top flat 10 and tergite 20, a pair of three-dimensional fold can also be further equipped with 50 and cover plate 60.

As shown in figure 17, one of the features of the present invention is formed at the pattern of the upside extruded threads 31 on upper layer absorber 30 With the pattern for the downside extruded threads 41 being formed on lower layer's absorber 40.The extruded threads 31,41 being formed on each absorber 30,40 When in terms of in-plane, the pattern to cross one another at least partly is formed.Hereinafter, with regard to the pattern of each extruded threads 31,41, in detail It illustrates.

As shown in figure 17, upside extruded threads 31 are formed in the pattern of rectangular clathrate on upper layer absorber 30.This place " pattern of rectangular clathrate " of meaning refers to a plurality of extruded threads that are extended in parallel with length direction with and width direction extend in parallel A plurality of extruded threads intersect, and the pattern in the nonextruding region of zoning square shape.Especially in this embodiment, upside is squeezed The pattern formation of crimping 31 is squeezed crimping 31 and surrounds the nonextruding region 32 in four directions all as the regular pattern (pros of square The pattern of shape clathrate).In this way, at the aspect of upper layer absorber 30, can thought of as be formed with a plurality of upside extruded threads 31, by upside What nonextruding region 32 (hereinafter referred to as " the nonextruding region in upside ") and upside extruded threads 31 around the encirclement of extruded threads 31 intersected Intersection point portion 33 (hereinafter referred to as " upside intersection point portion ") person.

On the other hand, downside extruded threads 41 are formed in the pattern of rhomboid clathrate on lower layer's absorber 40.This place " pattern of rhomboid clathrate " of meaning, refers to a plurality of extruding extended for length direction and the inclined direction of width direction Line intersects, and the pattern in the nonextruding region of zoning rhomboid (diamond shape).Especially in this embodiment, downside extruded threads 41 Pattern formed by downside extruded threads 41 surround four directions nonextruding region 42 all as the rule of positive rhomboid (positive diamond shape) Pattern (pattern of positive rhomboid clathrate).In this way, at 40 aspect of lower layer's absorber, can also be squeezed thought of as a plurality of downside is formed with Crimping 41, the nonextruding region 42 (hereinafter referred to as " the nonextruding region in downside ") that surrounding is surrounded by downside extruded threads 41 and downside are crowded Intersection point portion 43 (hereinafter referred to as " downside intersection point portion ") person that crimping 41 intersects.

In addition, in this embodiment, upside extruded threads 31 are by making upper layer absorber 30 from skin forward surface side pressure It is formed under puncture.Similarly, downside extruded threads 41 are by keeping lower layer's absorber 40 concave from skin forward surface side compression It is formed.Therefore, the position that downside extruded threads 41 are formed on lower layer's absorber 40 is absorbed in overlapping upper layer absorber 30 and lower layer The state of body 40 can form gap therebetween.

Figure 18 and Figure 19 is the pattern for the upside extruded threads 31 for showing overlapping square lattice shape and positive rhomboid clathrate Downside extruded threads 41 pattern state.Such as learnt by each figure, in this embodiment, the area in the nonextruding region in upside 32 More than the area in the nonextruding region in downside 42.Therefore, in overlapping upper layer absorber 30 and lower layer's absorber 40, downside is nonextruding Region 42 (positive rhomboid), which becomes, to be accommodated in the range of the nonextruding region 32 (square) in upside.

Herein, the pattern of the extruded threads of the second invention shown in Figure 17 to Figure 19 and the first hair illustrated with reference to Fig. 3 to Fig. 5 The pattern of bright extruded threads is common.Therefore, the pattern of the extruded threads of above-mentioned the first invention can be suitable for squeezing for the second invention The pattern of crimping.The pattern of extruded threads about the second invention can quote saying for the pattern of the extruded threads of above-mentioned the first invention It is bright, omit detailed description.

In addition to the above construction, also as shown in figure 17, slit 36 is formed on upper layer absorber 30.Slit 36 be with Centered on the lower crotch 3 of absorbent commodity 100, be formed as the elongated summary elliptical shape extended to length direction.In addition, slit 36 be closed at both ends poroid of length direction.Slit 36 is formed in the pattern of upside extruded threads 31 of square lattice shape, even It is connected to a plurality of upside extruded threads 31.More specifically, the linear upside extended along the length direction of absorbent commodity Extruded threads 31 are connected to the both ends part of the length direction of slit 36.In addition, extend along the width direction of absorbent commodity Linear upside extruded threads 31 are connected to the left and right ends part of the width direction of slit 36.Therefore, it lodges in slit 36 The body fluid in portion can be spread along length direction from upside extruded threads 31 to absorbent commodity and width direction.

In addition, as shown in figure 18, in the state for engaging upper layer absorber 30 with 40 lamination of lower layer absorber, learning lower layer The a plurality of downside extruded threads 41 of absorber 40, the nonextruding region 42 in multiple downsides and multiple downside intersection points portion 43 and upper layer absorber 30 slit 36 overlaps.First, it is overlapped by slit 36 and downside extruded threads 41, the body fluid lodged in slit 36 can be under Side extruded threads 41 are spread.In addition, overlapping by the nonextruding region 42 of slit 36 and downside, the nonextruding region 42 in downside can be made direct Absorb the body fluid lodged in slit 36.Furthermore downside intersection point portion 43 is it may be said that function as diffusion of body fluids route hinge.Cause This, is overlapped by slit 36 and downside intersection point portion 43, and body fluid can be widely diffused down centered on this downside intersection point portion 43 Layer absorber 40.

In addition, in this embodiment, the downside extruded threads 41 that overlap with the slit 36 of upper layer absorber 30 extend pair In the length direction of absorbent commodity and the inclined direction of the two of width direction (i.e. tilted direction).Therefore, by slit 36 The body fluid of contact downside extruded threads 41 can be spread along downside extruded threads 41 to tilted direction.

Furthermore it in this embodiment, illustrates with the pattern of the bigger square lattice shape of nonextruding region area It forms upside extruded threads 31, form downside extruded threads 41 with the pattern of the smaller positive rhomboid clathrate of nonextruding region area Example.However, the pattern of this extruded threads can also be exchanged in upside extruded threads 31 and downside extruded threads 41.That is, can also fit It uses the pattern of the square lattice shape as the pattern of downside extruded threads 41, be applicable in the pattern conduct of positive rhomboid clathrate The pattern of upside extruded threads 31.

(3. the 3rd implementation form)

Then, with reference to Figure 20 to Figure 22, just the absorbent commodity about the 3rd implementation form of the second invention illustrates. About the 3rd implementation form, omitted the description relative to construction identical with the 1st implementation form and the 2nd implementation form, with It is illustrated centered on the different construction of 1st and the 2nd implementation form.

Figure 20 (a) and be (b) that separation shows upper layer absorber 30 and lower layer's absorber 40, Figure 20 (c) and be (d) display The section shape of XX-XX.Figure 21 (a) is the state for showing overlapping upper layer absorber 30 and lower layer's absorber 40, and Figure 21 (b) is Show the section shape of XXI-XXI.In addition, Figure 22 is the figure that amplification display is formed in the extruded threads 31 on upper layer absorber 30 The figure of the pattern of case and the extruded threads 41 being formed on lower layer's absorber 40.Furthermore although figure is omitted in Figure 20 and Figure 21 Show, but the 3rd implementation form described herein as is also same with the 1st implementation form, at least has top flat 10 and tergite 20, A pair of three-dimensional fold 50 and cover plate 60 can be further equipped with.

3rd implementation form be formed at the extruded threads 31,41 on each absorber 30,40 pattern and the 2nd implementation form not Together.As shown in Figure 20 to Figure 22, upside extruded threads 31 are formed in the pattern of positive rhomboid clathrate on upper layer absorber 30, under Side extruded threads 41 are formed in the pattern of square lattice shape on lower layer's absorber 40.So-called positive rhomboid clathrate herein Pattern illustrates substantially the same with the pattern of square lattice shape and in the 2nd implementation form.However, in the 3rd implementation form Aspect, the state of absorber 30 and lower layer's absorber 40 on overlapping upper layer, the positive rhomboid lattice being formed on upper layer absorber 30 The relative position relation of the pattern of the pattern of sub- shape and the square lattice shape being formed on lower layer's absorber 40 is but implemented with the 2nd Form is different.
