To the skin contact surface side of the sanitary napkin in this embodiment 100, implement the anti-bakie of pushing from skin contact surface side to the absorption portion 3 of face sheet 15.Anti-bakie 5 is at the length direction central part P of absorbent core 10; With the excretory portion is that center configuration is in the width left and right sides; Along with the front and back end of above-mentioned two anti-bakies near absorbent core 10, crooked to the center direction of absorbent core 10 gradually, front end, rear end unanimity.Be endless loops ground when in other words, anti-bakie 5 is overlooked continuously and be disposed at the skin contact surface side of sanitary napkin 100.In addition, the shape of anti-bakie 5 does not have special qualification, and in this embodiment, front end, the rear end of anti-bakie 5 is consistent to be endless loops ground continuously, and still, front end, rear end also can be interlaced, preferably suitably determine according to purposes.In addition, excretory portion be meant excremental parts such as directly accepting menses or leucorrhea and near.
Details about the material of the sanitary napkin that constitutes this embodiment and size etc. will be set forth in the back; But in this embodiment; Face sheet 1 is from the rapid viewpoint that absorbs the excretory body fluid of institute and transmit to absorber and touch the good viewpoint of skin sense, uses hydrophilic hot-wind nonwoven cloth (air-through nonwoven).In addition, as back-sheet 7, use poisture-penetrability thin film with monolayer with aeration.As absorption portion 3, use the material that constitutes by paper pulp fiber and super absorbent polymer.As surrounding sheet material 2, use the difficult water miscible napkin that does not have retractility.In addition, the non-skin contact surface side of sheet material 7 overleaf applies and is used for sanitary napkin 100 is fixed in the bonding agent (not shown) of clothes.Sanitary napkin 10 is adhesively fixed on the clothes of user by this binding agent.The sanitary napkin 100 of this embodiment wearer's skin contact surface according to its face sheet side direction; And its length direction disposes from hypogastric region to buttocks; In other words, make its width dispose and wear use towards the direction of the line that connects the right lower limb of left lower limb.
In the present invention, short of special explanation is called skin face side or skin contact surface side or face side with a side that contacts human body, and a side of contact underwear is called non-skin face side or non-skin contact surface side or rear side.In addition, the direction that is positioned at the front side of human body when wearing is called the place ahead, and its end is as leading section, and the direction that will be positioned at rear side is called the rear, and its end describes as rearward end.In addition, the front of sanitary napkin or the normal direction at the back side are called thickness direction, its amount is called thickness.In addition, when overlooking sanitary napkin, the direction that length is arranged relatively is called length direction, is called width with the orthogonal direction of this length direction.In addition, above-mentioned length direction typically wear under the state consistent with the fore-and-aft direction of human body.
The skin contact surface side of the sanitary napkin 100 in this embodiment is provided with through implementing the anti-bakie 5 that concavo-convex processing (emboss) forms.In addition, the absorbent core 10 in the sanitary napkin 100 has the aggregation G (symbol as among the figure is not represented) of independently little absorption portion 3.Absorbent core 10 is aggregation G of little absorption portion 3; Thus; Adapt to " health fitness " and the action of following the wearer well of the fluctuating of skin face, " the action tracing ability " that prevents to produce with skin the part gap is high, will set forth its details in the back.Fig. 2 (i) is the axonometric chart of the part of the anti-bakie 5 that the absorption portion this embodiment 3 is implemented seen from the width cross section.
Anti-bakie 5 in this embodiment forms through push (extruding) of concavo-convex processing, and face sheet 1, the upside 21 that surrounds sheet material 2 and absorption portion 3 are engaged, and has the effect that departs from that suppresses above-mentioned each parts.On the other hand, anti-bakie 5 parts that are pressed through concavo-convex processing are high in the interfibrous density of this part, and therefore, capillary force is higher than other the part that is not pressed.Therefore, even move laterally to the mode of the excretory liquid of central authorities with diffusion, it moves and is stopped in anti-bakie 5 parts, and liquid is remained in the inboard of the anti-bakie 5 of enforcement in the form of a ring, can prevent to ooze out laterally from here.In aforesaid way, if the additional anti-bakie of pushing whole absorber, so, usually in this part, the rigidity of product strengthens, and is difficult to the fluctuating distortion along health, and fit descends.In contrast, the sanitary napkin 100 in this embodiment has the flexible of Fig. 2 shown in the (ii) regional W that releases, and thus, can realize high pliability at the easy enhanced leakproof slot part of rigidity.
The above-mentioned flexible regional W that releases is formed at: the zone that the anti-bakie 5 that alongst extends that sanitary napkin 100 is implemented and the 3 spacer portion m along the width extension separated from one another of absorption portion intersect.In the present invention, the spacer portion of absorbent core is meant, existing when the part of absorbent core is cut off and overlooks does not have the part of parts, comprises also that main parts part is lacked to remove, in the meaning of the successive structure of this part.In this embodiment, in absorption portion not by mutual cut-out, yet, surround sheet material in this cut-off parts and constitute spacer portion m continuously.
Spacer portion m is the zone that on the path of the anti-bakie 5 that extends along the length direction of absorbent core, does not have absorption portion 3, be have along back-sheet 7 with surrounding sheet material 2 butts engaged junction surface w
1Form with the profile along absorption portion 3, absorption portion 3 and encirclement sheet material 2 are in disengaged w of disengaged state
2The zone.Through concavo-convex part of pushing, there are not the parts with thickness of absorption portion 3 in the flexible regional W that releases, can not take place because of the excessive densificationization due to pushing, and consequently, inflexible rising is inhibited.Thus; In the sanitary napkin 100 in this embodiment; For the enhanced easily anti-bakie that alongst extends of rigidity; Alternate flexible area distribution can significantly not destroyed the good fit as the characteristic of the absorbent core 10 that has at least the spacer portion m that is spaced apart along width betwixt.
Flexible in this embodiment regional W that releases also brings into play distinctive liquid diffusibility.Below, this point is carried out detailed slightly explanation.
At first, according to Fig. 4 (a) existing concavo-convex processing situation is described.Among the figure, direction o is the width outside of absorbent core, and direction i is width center direction (an excretory portion direction).In addition, the expression shown in the pecked line is from the diffusion zone Q of the liquid of excretory portion discharge.Diffusion shape for liquid adopts modelling to represent, can be the shape identical with diagram in embodiments of the present invention.According to operating position, the excretory amount of liquid of institute is big, and the situation that grow the service time of sanitary napkin is a lot.Suppress anti-bakie 5 the liquid diffusion effect as stated, but in this case, the excretory liquid holdup of institute is in the inside of the anti-bakie that surrounds excretory portion circlewise, the absorber outside being difficult to use is easy to generate alluvial etc. in this part sometimes on the contrary.In addition, if the excretion of body fluid is a lot of a period, the liquid that then is detained by the anti-bakie that alongst extends 5 preventions emits just as these dykes and dams breach a dyke quickly.So if its amount is a small amount of, so, the absorption portion in the width outside that is arranged in above-mentioned anti-bakie can draw this effusive body fluid and deal with, still,, then do not crossed absorption portion and spill by the body fluid of the surplus that attracts immediately if its amount too much.When the body fluid that is absorbed the central part P that remains on absorbent core at the body movement according to the wearer was extruded, this situation became obviously, caused occurring the side leakage of making underwear and clothes etc. dirty.
In contrast, in the sanitary napkin of this embodiment, the effect below the performance makes it be difficult for taking place above-mentioned side leakage.In the sanitary napkin 100 in this embodiment; Under the few situation of the amount of excretory liquid; Shown in Fig. 3 (b); Utilize anti-bakie 5 certain part by the capillary force of the absorption portion 32 of densificationization, stop the diffusion laterally of the diffusion Q of liquid, prevent from the mobile caused side leakage of the absorption portion 31 excretory liquid of central part P side.Its effect is same with the effect that obtains through general concavo-convex processing.On the other hand, under the more situation of excretory liquid, bring into play the function that does not have in the existing parts, shown in Fig. 3 (c), in flexible was released regional W, liquid was emitted at every turn slightly, carried out the diffusion Q of stable liquid laterally from anti-bakie 5.Particularly; As stated, in flexible is released regional W, on the path of anti-bakie 5, spacer portion m is arranged; Even the liquid that does not absorb fully and overflow is arranged in the absorption portion of inboard; Also produce the face sheet of liquid permeability and this flexible of surrounding sheet material institute formation wall are released regional W part as the liquid stream S of the liquid of stream, can it hitherward moved slightly at every turn in the absorption portion 33 in the outside with its absorption.In addition, has parts non-stick portion w each other at the flexible regional W that releases
2, in this part, also guarantee stream.That is, flexible is released regional W under the saturation of the absorption portion 31 of the inboard of anti-bakie 5, will be here as flow velocity adjustment valve; Moderately reduce liquid measure and move it; Thus, in the absorption portion 33 in the outside of preventing bakie 5, absorb this liquid of maintenance, can effectively utilize this part.Consequently, in this embodiment, when have a large amount of fluid drainage a period, and according to the action liquid of wearer's health when central authorities are extruded, also performance keeps the dry feeling of appropriateness, prevents the action effect that side leakage is good like this.
In addition, in this embodiment, surrounding sheet material 2 is hydrophilic sheet materials, in order to the diffusion effect of further raising aforesaid liquid.That is, possess hydrophilic property is than face sheet 1 height, and the high position of density at least, therefore, and can be with discharge liquors such as menses from face sheet 1 rapid sucking-off, and give absorption portion 3.In addition, surround the little thin material of the logical out of date resistance of sheet material 2 preferred liquid, and the crooked easily pliable material of the spacer portion m of absorption portion 3 each intervals.Thus, the absorbability of sanitary napkin becomes higher, and can improve the flexibility of whole absorber.
Here; If the absorbent core 10 to this embodiment carries out detailed elaboration; Then according in the skin contact surface side of surrounding sheet material 22 as the non-skin face side of non-retractility; A plurality of respectively independently absorption portion 3 under naturalness, have the mode of predetermined gap d, e (with reference to Fig. 1) each other, along direction in length and breadth and be set up.In the absorber 10 of this embodiment, the mode that absorption portion 3 arranges according to staggered (word shape) disposes.In the present invention, staggered arrangement is meant: when the row of the arranged side by side a plurality of absorption of configuration portion, and the arrangement that the spacing of the absorption portion in the row of adjacency is staggered.In other words, this arrangement is, when on orthogonal direction, the absorption portion 3 of the row of regulation being carried out projection, with the inconsistent configuration of projection image of the absorption portion 3 of adjacency.According to Fig. 1 this object lesson is described, the row B of absorption portion that (directions X) extends alongst makes its mutual repetition in abutting connection with the row A of absorption portion arranged side by side.Center when supposing to overlook the row B of absorption portion with the bearing of trend of the row B of absorption portion on orthogonal direction (Y direction) go up successive boost line t
bOn the other hand, suppose same boost line t among the row A of absorption portion
aThis boost line t
aAnd boost line t
bAccording to the mode of the half pitch that staggers each other, that is, and boost line t
aWith boost line t
bThe mode that in integral body, equates of interval arrange, constitute staggered arrangement.Variation as this embodiment; For example enumerate; Revolve width that turn 90 degrees, absorber (Y direction) in the direction that spacing is staggered and go up setting absorption row A of portion and the row B of absorption portion, the embodiment that the boost line that (directions X) extended departs from.In addition,, can be described as block cloth so,, enumerate and tiltedly knit block (twill masonry), herringbone block (herringbone masonry), Carapax Et Plastrum Testudinis block (hexagonal masonry) etc. as this variation if liken staggered arrangement to stone-laying.
This absorption portion 3 is long rectangular shape on the length direction when overlooking, in the cross section (with reference to Fig. 2 (i)) be rectangular rectangular shape long on the width, still, in the present invention, this shape does not have special qualification, can adopt shape arbitrarily.In this embodiment, absorption portion 3 is made up of paper pulp fiber and super absorbent polymer, and its profile also can not be illustrated the sort of solid shape, preferred as a whole above-mentioned three-dimensional shape.In addition, the arrangement in length and breadth of absorption portion 3 also is not limited to above-mentioned, preferably suitably decides according to purposes.
The absorbent core 10 of this embodiment is made up of the set of a plurality of independently absorption portion 3, and therefore, " the health fitness " that adapt to the fluctuating of skin face compared significantly with the big absorber of common one and improved.In addition, also follow wearer's action well, prevent and skin between to produce " the action fitness " in part gap high.According to this embodiment, can realize this good morphotropism simultaneously and not kept by the absorption of the liquid etc. about this distortion.
The action effects that the cut absorption portion 3 that in this embodiment, is adopted is surrounded on the sheet material 22 in non-skin face side according to a plurality of specific alignment arrangements carry out more detailed elaboration.At first, enumerate the extremely situation of the skin face of complicated bend that also is fit to well.For example, make sanitary napkin along the time from the point of release to buttocks, crooked along the buttocks circle to length direction, still, by the existing absorber of interior bag, in the ordinary course of things with other parts mutually specific rigidity significantly improve bending sometimes.Cause bends the relation of distortion with this, and inner absorber is difficult to get into anal cleft portion, produces big slit here sometimes.That is, be difficult to guarantee simultaneously the bending of length direction and the bending of width, be difficult for obtaining sufficient fit.So menses etc. move through the space that produces in anal cleft portion easily, become the reason that h.d. spills to the back direction.
In contrast; If use the sanitary napkin 100 of the absorber of this embodiment, so, gently to buttocks circular bend and mutually fit with it; And also moderately get into anal cleft portion; Become so-called saddle face shape or hyperbolic parabola shape, in anal cleft portion, also can not produce the slit basically, fit with it.Thus, realize near the point of release to the buttocks fabulous fitness of seamless unoccupied place butt substantially.Stand up or during walking in wearer sleep, also according to and follow the activity of skin face, therefore, the slit can not enlarge, and continues good fit.
The size of the absorption portion 3 of this embodiment has no particular limits, if but the use of consideration sanitary napkin is also different slightly because of the sanitary napkin difference of making, but length direction length h
1(with reference to Fig. 1) is preferably 10～40mm, more preferably 15～20mm.Width length h
2Be preferably 5～20mm, more preferably 10～15mm.In addition, spacer portion gap d, e are preferably 0.1～5.0mm, 0.5～2.0mm respectively.In addition; The shape of anti-bakie 5 etc. also has no particular limits; But; If consider above-mentioned good pliability and liquid diffusibility, then the thickness of face sheet 1 preferably has thickness more than the 0.5mm, in anti-bakie 5 parts, is compressed into below the 0.3mm beyond anti-bakie 5 parts, preferably has thickness more than the 2.0mm in addition, in leakage barriers 5 parts, is compressed into below the 1.0mm 5 ones of anti-bakies at the thickness u of absorption portion 3 (Fig. 2).In addition, the width h of the bottom land of anti-bakie
3Be preferably 1.0mm～2.0mm.In addition; In this embodiment; Thickness beyond the anti-bakie 5 is meant: with size is that 37mm * 37mm, thickness are that the acrylic panel of 3mm is placed on face sheet 1 or the absorbent core 10; (laser head trade name: LK-G30, displacement meter trade name: the thickness of LK-GD500) measuring, the thickness in anti-bakie 5 parts are meant the direct thickness of measuring with the non-contact laser displacement meter of KEYENCE manufactured to the non-contact laser displacement meter of use KEYENCE manufactured.
Fig. 4 is expression as other the floor map of absorption portion 3 and the relation of anti-bakie 5 of embodiment (embodiment 2) of the present invention.Except the arrangement of absorption portion 3, all the other are identical with the mode in the first embodiment, do not represent among the figure that face sheet 1, back-sheet 7, upside surround sheet material 21 and sidepiece sheet material 8, and downside surrounds sheet material 22 usefulness one pecked line and representes.In this embodiment, absorption portion 3 is employed in when direction is to 3 projections of absorption portion in length and breadth and arranges with adjacent absorption portion 3 consistent grid (checker).That is, adopt when being projected in a plurality of absorption portion on length direction and the width all eclipsed in any one direction configuration of its projection image.So, length direction spacer portion m
