The specific embodiment
The present invention provides and can effectively utilize the absorbing surface that is positioned between leakage, can absorbing surface is stabilized in skin one side of wearer and make its protruding absorbent commodity simultaneously.In addition, the present invention also provides a kind of absorbent commodity that possesses leakage, and it can further improve the absorbent commodity of anti-side leakage property.
Below, according to embodiment preferred with reference to description of drawings the present invention.Fig. 1 representes from the vertical view of face sheet side observation as the sanitary napkin of an embodiment of absorbent commodity of the present invention, the II-II line profile of Fig. 2 presentation graphs 1.
As depicted in figs. 1 and 2; The sanitary napkin 1 of this embodiment has the shape of lengthwise, possesses face sheet 2 as liquid permeability positive layer, as the back-sheet 3 of the back layer of liquid impermeability and the absorber 4 as the liquid retainability absorbed layer between face sheet 2 and back-sheet 3.Left and right sides portion its length direction of upper edge in the face sheet side of sanitary towel 1 disposes a pair of leakage 5,5.Leakage 5 erects near the edge, the left and right sides of absorber 4 respectively.
In addition, when mentioning " length direction " and " width ", short of special instruction, then expression " length direction of absorbent commodity " and " width of absorbent commodity " respectively.When mentioning " upper surface " and " lower surface ", expression " skin contact (face of a side) " reaches " non-skin contact (face of a side) " respectively.
Back-sheet 3 extends to the outside from the side of absorber 4, on the position of opposed A of the excretory portion of sanitary towel 1, is formed with a pair of alar part 72.In addition, though not shown providing is formed with on the underwear opposed faces of sheet material 3 and alar part 72 overleaf and is used for sanitary towel 1 is fixed on the adhesive phase on the underwear.This adhesive phase is by not shown peeling paper protection.
The leakage 5 that is configured in 1 left and right sides portion of sanitary towel is that a banded sheet material is processed into sleeve-like and is the T font.Leakage 5 possesses the 5a of basal wall portion.The upper end that the 5a of basal wall portion has stiff end and free state, this stiff end erects from back-sheet on the position near the outside at the side than absorber 4 slightly.
Dispose a plurality of elastomeric element 5c that on the length direction of leakage 5, extend on the facial 5b of contact skin.As the constituent material of elastomeric element 5c, get final product not special restriction so long as be used for the material of common absorbent commodity.For example, can preferably use the foaming body and the natural rubber of TPO and polyurethanes.The shape of elastomeric element 5c can be wire, band shape, film like etc.Use the elastomeric element of wire in this embodiment.Elastomeric element 5c is configured on opposed A of excretory portion of sanitary towel 1 at least.Elastomeric element 5c is fixed in the sheet material that forms leakage 5 with elongation state.As this fixing means, can use heat seal, hotmelt etc.The percentage elongation of each elastomeric element 5c much at one.
Under the naturalness of sanitary towel 1, through the contraction of elastomeric element 5c, leakage 5 erects reliably.According to the leakage 5 of this formation, the effect of the planar sealing that the upper surface that can realize the facial 5b of contact skin flexibly and is planarlyly fitted with the huckle of wearer.Its result is not easy to receive position that the action by wearer causes and influence such as moves, and can effectively prevent leakage.In addition; Even if leakage 5 receives the influence of wearer action easily and overwhelms to the inside; But, the strength of leakage 5 outward inclining is played a role, thereby can prevent effectively that leakage 5 from overwhelming to the inside through being configured in tension force near the elastomeric element 5c in the width outside.Its result has highly kept the applying degree of the facial 5b of contact skin to huckle.Particularly, near the left and right sides free end that elastomeric element 5C is configured in the facial 5b of contact skin, facial 5b is more stable towards stretching out of horizontal direction for contact skin, and above-mentioned planar sealing effectiveness further improves.
In leakage 5, on the position of pro-quadrate part B and back quadrate part C, the part of stretching out to the inside among the facial 5b of contact skin is fixed on the face sheet 2.The facial 5b of contact skin be not fixed on the face sheet 2 on the position of opposed A of excretory portion.Thus, leakage 5 is more prone to erect on the position of opposed A of excretory portion, and the back-sheet side of sanitary towel 1 bends to convex, the shape that sanitary towel's integral body becomes and the wearer build coincide.Its result, the upper surface of the facial 5b of contact skin more stably fits in the huckle of wearer, and planar sealing effectiveness further embodies.Particularly; Shown in this embodiment; If at the arranged outside alar part 72 of the set-up positions of leakage 5, then under the wearing state of sanitary towel 1, because the turning back of alar part 72; The cardinal extremity position stability ground power toward the outer side of leakage 5 is played a role, so the liquid containing of the skin opposed faces side of sanitary towel 1 zone becomes big.
Because the cardinal extremity position stability ground power toward the outer side of leakage 5 is played a role; And the end is fixed on the end, length direction front and back of sanitary towel before and after the length direction of the facial 5b of contact skin; Therefore the facial 5b of the contact skin of leakage 5 is not easy to receive the influence of the huckle action of wearer, planarly stably shows.And it is big that the liquid containing zone of skin opposite side also further becomes.Because the length of sanitary towel is long more, then the distance between the fixed position of end is big more before and after the length direction of the facial 5b of contact skin, so the influence that the action of the huckle of wearer causes diminishes.Its result can obtain better effect.
The face sheet side of sanitary towel 1 is formed with the anti-bakie 8,8 to the length direction extension of sanitary towel 1 respectively on its both sides.Each anti-bakie 8 is through utilizing the isobaric solid yardage method of embossing with face sheet 2 and absorber 4 compactings and integrated formation from the face sheet side.Aforesaid each leakage 5 lays respectively at the outside of each anti-bakie 8.Each anti-bakie 8 forms with respect to the almost symmetric shape of the longitudinal centre line of sanitary towel 1.The front and back end of each anti-bakie 8 interconnects, and becomes the shape of sealing thus as a whole.
In each anti-bakie 8, the part that is positioned at opposed A of excretory portion becomes convex (following this part is called central bend groove 8a) towards the width outside curve of sanitary towel 1.The front and back of central bend groove 8a before and after the length direction of sanitary towel, extend respectively and before forming side channel 8b with after side channel 8c.The anti-bakie 8 that is made up of central bend groove 8a and the preceding side channel 8b that extends before and after it and back side channel 8c almost spreads all over the total length of sanitary towel 1 and extends.Before side channel 8b same with back side channel 8c and central bend groove 8a, become convex towards the width outside curve of sanitary towel 1.Its result, each anti-bakie 8 has the 9a of the portion of tightening up on the position of the connecting portion of central bend groove 8a and preceding side channel 8b.In addition, on the position of central bend groove 8a and the connecting portion of back side channel 8c, has the 9b of the portion of tightening up.
As shown in Figure 2, in sanitary towel 1, when on its width, observing, different with the thickness of the outside absorber 4 of anti-bakie 8 between anti-bakie 8,8.Can be known by Fig. 2, between the anti-bakie 8,8, promptly be closed 8 area surrounded of anti-bakie of shape, compare with the outside of anti-bakie 8, it is big that its thickness becomes.In this embodiment, the constituent material of absorber 4 is identical with the outside of anti-bakie 8 between anti-bakie 8,8, so the thickness difference of absorber 4 poor corresponding to the mass area ratio of absorber 4.That is to say; In sanitary towel 1, the absorber 4 that is positioned between the anti-bakie 8,8 is different with the mass area ratio of the absorber 4 that is positioned at anti-bakie 8 outsides; The absorber 4 that is positioned between the anti-bakie 8,8 is higher than the mass area ratio of the absorber 4 that is positioned at anti-bakie 8 outsides.Its result in sanitary towel 1, prevent that bakie 8 area surrounded compare with the neighboring area that is positioned at anti-bakie 8 outsides, becomes the shape of convexity.
According to the sanitary towel 1 of this embodiment with above formation, under the wearing state of sanitary towel 1, the horizontal compression stress that comes from that causes when the action by wearer is applied to 1 last time of sanitary towel, each leakage 5 become be difficult to approaching each other.That is, be difficult to covered, particularly be difficult to covered by the facial 5b of each contact skin by each leakage 5 as the face of the face sheet side of the absorbing surface of sanitary towel 1.Its result can effectively utilize absorbing surface, and leak preventing effect improves.Its reason is that the anti-bakie 8 that is positioned at opposed A of excretory portion of sanitary towel 1 has formed the central bend groove 8a that becomes convex towards the width outside curve of sanitary towel 1.Say that at length be applied to 1 last time of sanitary towel when coming from horizontal compression stress, this compression stress is difficult to be delivered to the inside of absorber 4 owing to the arch bridge shape of central bend groove 8a is dispersed on the length direction of groove.As a result, as shown in Figure 3, serve as the bending starting point with central bend groove 8a, sanitary towel 1 becomes outer easily and rolls over.Particularly; If tighten up the 9a of portion in the formation of the front and back of central bend groove 8a, 9b then transmits at the length direction of central bend groove 8a from the compression stress quilt that laterally is applied in the sanitary towel 1 more effectively; Therefore, can outer folding with central bend groove 8a as the sanitary towel 1 of bending starting point.
Relative therewith; In existing sanitary towel 1 ' shown in Figure 4; Promptly do not become the sanitary towel of convex, be applied to 1 ' last time of sanitary towel when coming from horizontal compression stress, shown in Fig. 5 (a) towards the width outside curve at the anti-bakie 8 ' that is arranged in opposed A ' of excretory portion; In case bakie 8 ' is the bending starting point, folding in sanitary towel 1 ' is prone to take place.When interior folding is obvious, shown in Fig. 5 (b), locate to produce fold at the facial 5b ' of the contact skin of leakage 5 ', the planar sealing effectiveness of contact skin face 5b ' reduces.Take place Fig. 5 (a) with (b) shown in the reason of phenomenon be to prevent that bakie 8 ' can't stop from it laterally to be applied to the compression stress in the sanitary towel 1 ', and cause this compression stress to be delivered to the inside of absorber 4.This phenomenon is remarkable especially when tighten up the width inboard at the anti-bakie 8 ' that is positioned at opposed A ' of drainage.
As stated; The sanitary towel 1 of this embodiment is characterised in that; It has leakage 5; This leakage 5 possesses from the front end of the 5a of basal wall portion in the horizontal direction with the facial 5b of planar contact skin of stretching out, and the anti-bakie 8 that wherein is positioned at opposed A of excretory portion becomes convex towards the width outside curve of sanitary towel 1.According to the sanitary towel 1 of this embodiment, can not damage the aforesaid various advantages that possesses the leakage 5 of the facial 5b of contact skin, and can solve peculiar problem when utilizing this leakage 5.Therefore; In the sanitary towel that possesses leakage with the facial 5b of contact skin; Even if form towards the width outside curve of sanitary towel 1 become convex anti-bakie 8, be central bend groove 8a, can not reach the remarkable result that the sanitary towel 1 of this embodiment is reached.
As shown in Figure 3, in the sanitary towel 1 of this embodiment, because sanitary towel 1 serves as to bend starting point and outer folding with central bend groove 8a easily, so absorbing surface, promptly the face of face sheet side is stably protruding, and fits in the health of wearer.Its result, the fit of sanitary towel 1 improves, and leak preventing effect further improves thus.Particularly, because the bossing of absorber 4 is closed 8 encirclements of anti-bakie of shape, so the planar stability of this part further improves.
The inventor's etc. result of study shows that protruding in order further stably to make absorbing surface, its effective method is to improve the mass area ratio that is positioned at the absorber 4 between the anti-bakie 8,8.The absorber 4 that is positioned between the anti-bakie 8,8 is the high absorbers of mass area ratio, this before narrated, if this mass area ratio is 300～1500g/m
2, 500～1200g/m particularly
2The time, can further stably make absorbing surface protruding.In addition, serve as the viewpoint that the bending starting point is extruded to bodyside with central bend groove 8a easily from make sanitary towel 1 through side applied pressure from sanitary towel 1, mass area ratio also is favourable in this scope.
In addition, in above-mentioned mass area ratio scope, at 300～900g/m
2Scope in the time, become the bending starting point effect be main; At 900～1500g/m
2Scope in the time, except the effect that becomes the bending starting point, high portion somewhat deformed is a drum type in also can producing, thereby is easy to protruding effect.
The mass area ratio that is positioned at the absorber 4 between the anti-bakie 8,8 as previously mentioned.On the other hand; From further stably making protruding viewpoint of absorbing surface and sanitary towel 1 be prone to central bend groove 8a is the viewpoint that the bending starting point is extruded to bodyside, and the mass area ratio that is positioned at the absorber 4 in anti-bakie 8 outsides is preferably 100～400g/m
2, 150～300g/m especially preferably
2
From same viewpoint, in absorber 4, when overlooking absorber 4, the profile in the above-mentioned zone that becomes high mass area ratio is preferably consistent with the shape that becomes close-shaped anti-bakie 8.In order to constitute like this absorber 4, for example can absorber 4 be processed lower floor's absorber and range upon range of above that 2 layers of structure of upper strata absorber, and form and prevent bakie 8 along the profile down of overlooking of upper strata absorber.
In addition, as shown in Figure 6 from same viewpoint, the ratio L/D that tightens up the distance B between the summit of length L and this line segment and central bend groove 8a of line segment of the 9a of portion, 9b before and after the connection of central bend groove 8a is preferably 2.5～20, is preferably 5～15 especially.About the value of L and D itself, L is preferably 50～100mm, is preferably 60～80mm especially, and D is preferably 5～20mm, is preferably 5～10mm especially.
As shown in Figure 2; The stationary state of the stiff end of the 5a of basal wall portion of leakage 5 not only can be arranged to constitute the pattern that the both sides of the sheet material of leakage 5 extend out laterally and are fixed from the bottom of absorber 4, also can be arranged to the pattern shown in Fig. 7 (a) and Fig. 7 (b).In Fig. 7 (a), the both sides of the sheet material of formation leakage 5 extend out to the sidepiece of sanitary towel from the stiff end of the 5a of basal wall portion.Among Fig. 7 (b), a sidepiece of the sheet material of formation leakage 5 extends out to the top of absorber 4 from the stiff end of the 5a of basal wall portion, and the other side of this sheet material extends out to the lateral edge portion of sanitary towel from the stiff end of the 5a of basal wall portion simultaneously.
Then other embodiments of the present invention are described with reference to Fig. 8～Figure 19.For these other embodiments, the aspect different with the embodiment of explaining before described, then omit explanation for identical aspect.The aspect that do to specify can suitably adopt to before the explanation carried out of the embodiment explained.
The sanitary napkin 1 of Fig. 8～embodiment shown in Figure 10 possesses face sheet 2, liquid impermeability or the back-sheet 3 of liquid difficulty permeability and the absorber 4 of liquid retainability of liquid permeability.Absorber 4 is between face sheet 2 and back-sheet 3.
Shown in figure 10, absorber 4 has 2 layers of structure that are made up of upper strata absorber 41 and lower floor's absorber 42.Upper strata absorber 41 is compared with lower floor absorber 42, and length is short, narrow width.In addition, upper strata absorber 41 does not engage with lower floor absorber 42, and is positioned at the length direction central part and the width central part of sanitary napkin 1.Therefore, upper strata absorber 41 forms so-called middle high zone.
As shown in Figure 9, in sanitary towel 1, be positioned on the part of opposed A of excretory portion and be formed with the central bend groove 8a that becomes convex towards the width outside curve of sanitary towel 1.Extend in the front and back of the length direction of sanitary towel the front and back of central bend groove 8a, side channel 8b and back square groove 8c before forming respectively.The anti-bakie that is made up of central bend groove 8a and the preceding side channel 8b that extends before and after it and back side channel 8c spreads all over the almost total length of sanitary towel 1 and extends.Before side channel 8b same with back side channel 8c and central bend groove 8a, become convex towards the width outside curve of sanitary towel 1.Its result has formed on the position of the connecting portion of central bend groove 8a and preceding side channel 8b and has tightened up the 9a of portion.In addition, on the position of central bend groove 8a and the connecting portion of back side channel 8c, formed and tightened up the 9b of portion.
Like Fig. 8～shown in Figure 10, each groove 8a, 8b, 8c form through the bottom absorber 42 of integrated ground compacting face sheet 2 and absorber 4, and surround upper strata absorber 41.Each groove 8a, 8b, 8c engage face sheet 2 and lower floor's absorber 42, but do not engage face sheet 2 and upper strata absorber 41.And, when overlooking, the profile basically identical of the profile of upper strata absorber 41 and each groove 8a, 8b, 8c.Therefore, upper strata absorber 41 is sealed by face sheet 2 and the enclosed space that lower floor's absorber 42 constitutes.
Face sheet 2 covers the whole zone of the skin contact side of absorber 4, but does not cover side 43.Face sheet 2 is so long as the sheet material of liquid permeability gets final product, and not special restriction for example is made up of a plurality of concavo-convex sheet materials to the side-prominent protuberance 24 of skin contact that have shown in Figure 11.The face sheet 2 that is made up of concavo-convex sheet material in this embodiment is made up of the 1st fibrous layer 21 of skin contact side and the 2nd fibrous layer 22 of non-skin contact side.The 1st fibrous layer 21 and the 2nd fibrous layer 22 localized heats are melt bonded, form heat fusing bonding part 23.The 1st fibrous layer 21 forms a plurality of protuberances 24 with elasticity of compression on the position beyond the heat fusing bonding part 23.
Above-mentioned concavo-convex sheet material can obtain as follows: utilize heat embossing with the regulation pattern will be melt bonded by the 1st fibrous layer 21 and the 2nd fibrous layer 22 localized heats that fiber assembly constitutes, make the 2nd fibrous layer 22 thermal contraction in the horizontal direction afterwards, thus the acquisition.At length say; Utilize that the heat fusing of heat embossing is bonding to carry out as follows: for example make the embossing face (side face of knurling rolls etc.) that is provided with a plurality of embossing pins regularly be crimped on the 1st fibrous layer 21 1 sides in the duplexer of the 1st fibrous layer 21 and the 2nd fibrous layer 22, make by the formation fibers melt of the 1st fibrous layer 21 on the hot pressed position of each pin and/or the 2nd fibrous layer 22.
The thermal contraction of the 2nd fibrous layer 22 is carried out as follows: for example constitute the 2nd fibrous layer 22 or make in the 2nd fibrous layer 22 and contain the heat-shrinkable fiber in advance by the heat-shrinkable fiber, make the 1st fibrous layer 21 and the 2nd fibrous layer adherent while of 22 heat fusings perhaps make both heat fusings bonding after, the 2nd fibrous layer 22 is carried out heat treated.A plurality of protuberances 24 are through making the 2nd fibrous layer 22 thermal contraction in the horizontal direction, form thereby make position beyond the heat fusing bonding part 23 of the 1st fibrous layer 21 be deformed into convex.
A plurality of heat fusing bonding parts 23 form loose point-like and zigzag regularly.Distance between the heat fusing bonding part 23 is certain basically.Each protuberance 24 becomes domed respectively, and its inside is full of the fiber that constitutes the 1st fibrous layer 21.In addition, the 1st fibrous layer 21 and the interface of the 2nd fibrous layer 22 that are formed with in the part of each protuberance 24 become the state that does not engage but fit.
The formation fiber of the 1st fibrous layer 21 does not preferably have the fiber of the fiber of heat-shrinkable or not thermal contraction under smaller or equal to the temperature of the heat shrink temperature of the formation fiber of the 2nd fibrous layer 22 basically.
As the formation fiber of the 2nd fibrous layer 22, preferably constitute and have the fiber of heat-shrinkable by thermoplastic, polymeric materials.And this formation fiber is preferably also represented the elastomer behavior after contraction.As the example of this fiber, can enumerate the potential crimping property fiber.Potential crimping property fiber in the 2nd fibrous layer 22 contain proportional 40～100 weight % that are preferably.The potential crimping property fiber is to have before being heated likewise to handle with the fiber that existing non-woven fabrics is used, and shows the fiber of spiral helicine curling character of shrinking through the heating under the set point of temperature.Through using the potential crimping property fiber, can make it show heat-shrinkable and elastomer behavior simultaneously.
The potential crimping property fiber is for example by constituting as the eccentric core-sheath-type of composition or the composite fibre of parallel type with 2 kinds of different thermoplastic, polymeric materials of shrinkage factor.As its example, can enumerate the fiber of being put down in writing among JP9-296325A, the JP2759331B.The 2nd fibrous layer 22 for example can contain this potential crimping property fiber in advance, and with the adherent while of the heat fusing of the 1st fibrous layer 21 or afterwards, through heating curling of its this fiber of performance is shunk.
Like Figure 10 and shown in Figure 12, on the length direction both sides of face sheet 2, engaging respectively has hydrophobicity side sheet material 6.Side sheet material 6 is engaged in the skin contact side of face sheet 2, and engages to the mode that the width outside extends out according to the length direction both sides of the edge from face sheet 2.
