Can be in the face side of sanitary napkin 1, dispose in the mode of the part of surrounding the contact scavenge port and to make surface sheet 3 and absorber 4 incorporate fit embossing 10.By disposing the compactness that fit embossing 10 can improve surface sheet and absorber, make body fluid be easy to move to absorber, and especially by promoting near the absorption above-mentioned fit embossing 10, the body fluid volume of side shifting outside fit embossing 10 be can reduce, thereby front and back seepage, horizontal seepage prevented.
On the other hand, face side both sides at sanitary napkin 1, respectively along its length and the roughly total length that spreads all over sanitary napkin 1 side non-woven fabrics 7,7 is set, the part of this side non-woven fabrics 7,7 is extended to the side, and forms wing flap W, W with the part of the back foil 2 of extending to the side equally.
From the function of being paid attention to, above-mentioned side non-woven fabrics 7 can use water-proofing treatment non-woven fabrics or hydrophilic treated non-woven fabrics.For example, if from paying attention to preventing that menses, leucorrhea etc. from soaking into or improves functional point of view such as skin sense of touch, then preferred use has applied silicon class, paraffin class, alkyl Chlorizate chromium (ア Le キ Le Network ロ ミ Star Network Network ロ リ De; Alkyl chromic chloride) the water-proofing treatment non-woven fabrics of class waterproofing agent etc.In addition, if pay attention to above-mentioned wing flap W, W is to the absorbability of menses etc., the hydrophilic treated non-woven fabrics that then preferred use makes by the following method, promptly utilize the chemical compound that in the manufacture process of synthetic fibers, makes possess hydrophilic property, for example coexistence such as the oxidation product of Polyethylene Glycol and polymeric method, or handle with the such slaine of butter of tin and the surface to be partly dissolved and to have the method etc. that porous makes the precipitation of hydroxide of metal again, make the synthetic fibers swelling or have porous, and use capillarity and give hydrophilic hydrophilic treated non-woven fabrics.
Lip-deep at surface sheet 3 is the scavenge port abutment portion at least, and devices spaced apart is formed with Duo Tiaogou, and forms patterns (decorative pattern) on surface sheet 3 surfaces.Below, illustration is formed at the ditch on surface sheet 3 surfaces and the pattern that is formed by above-mentioned ditch.
First embodiment
Fig. 3 is the vertical view of first embodiment of the sanitary napkin 1 that the present invention relates to of expression.Dispose ditch 31 on the whole surface of the surface sheet 3 of the sanitary napkin 1 of the manner, this ditch 31 forms the many patterns that have the swash on opposed summit at the width sidepiece.By each swash that ditch 31 forms, in illustrated example, form parallel to each other, but as long as swash is the shape that does not cross one another each other, and nonessential parallel.In illustrated example, ditch 31 is designed to make the waveform axle 2 of formed swash vertical with length direction, but is not limited to such shape (with reference to second embodiment).The preferably wideer scope of the scope of additional pattern on surface sheet 3 is preferably more than 20% of area of the skin abutment face of surface sheet 3, more preferably more than 25%.In addition, for the mobile length direction that is oriented to accompanying body fluid, more preferably above-mentioned swash extends to rearward end from the leading section of surface sheet 3.
Fig. 4 schematically represents the amplification plan view of the swash that ditch 31 forms.In addition, Fig. 5 represents vertical view that the III of Fig. 4 is partly amplified.The width 51 of ditch 31 is preferably 1.5～3.0mm, is preferably 1.0～2.0mm especially, and the interval 52 of ditch is preferably 2.0～5.0mm, is preferably 2.5～3.5mm especially.In addition, preferred ditch 52 is wider than ditch width 51 at interval.Ditch 31 side by side forms, perhaps after the thin slice raw material manufacturing of surface sheet is finished, forms by its face side being added hot compression (embossing processing) make constituting the thin slice raw material of surface sheet (being non-woven fabrics under this situation) time.When making the thin slice raw material of surface sheet, form under the situation of ditch, owing to do not add hot compression thereby can keep the original pliability of raw material, and under the situation that adds hot compression (embossing processing), when the gross area of ditch part, be that compression section is excessive, then can damage the flexibility of surface sheet.Therefore, form furrow width 51 less than ditch interval 52, and on the whole, be formed at the area of the area of the protuberance between the ditch greater than the recess that forms by ditch.On the other hand, when ditch at interval 52 when wide, then can't obtain to dispose the surface sheet that prevents that ditch 31 brings fully and break away from, keep resiliency, the good such effect of skin sense of touch.Therefore, furrow width 51 and ditch 52 more preferably are located in the above-mentioned scope at interval.
The swash that is formed by ditch 31 is preferably, and summit and width are vertically opposed, and wave height WH is 5～35mm at width, is preferably 10～25mm especially, and it is 40～130mm that wavelength WL is preferably at length direction, is preferably 80～120mm especially.If wave height WH is too short, then same when forming straight line along its length, the situation that the surface sheet shown in Figure 12 (C) breaks away from easily takes place.The long situation that the surface sheet disengaging easily takes place too of wavelength WL.On the other hand, under the long situation of wave height WH or under the too short situation of wavelength WL, body fluid easily takes place flow to width, thereby easily side leakage.Therefore, be preferably, wave height WH and wavelength WL are in above-mentioned scope.
Fig. 6 represents the schematic drawing of the width cutaway view of the surface sheet 3 of the manner and intermediate sheet 6.Ditch 31 can form when making the thin slice raw material of surface sheet, also can form by embossing processing after making the thin slice raw material.Be processed to form by embossing under the situation of ditch, can only be formed at surface sheet 3, but, be preferably in order to ensure the degree of depth of ditch, surface sheet 3 and intermediate sheet 6 is overlapping and they are carried out embossing processing integratedly.In this case, the preferred applying unit area weight of intermediate sheet is 18g/m
2Fluffy thin slice.When the weight per unit area of middle thin slice less than 18g/m
2The time, then shown in Fig. 6 (B), thereby the concavo-convex compactness that reduces with absorber can appear in the absorber butt side of intermediate sheet after the embossing processing.By the applying unit area weight is 18g/m
2Above fluffy intermediate sheet then also can make the absorption side of intermediate sheet keep smooth after the embossing processing, can keep the compactness with absorber.
Second embodiment
Fig. 7 represents the vertical view of second embodiment of the sanitary napkin 1 that the present invention relates to.In the manner, surface sheet 3 surfaces are formed with the ditch 71 of the swash shape that is made of straight line and curve, and the waveform axle L-4 of the ditch 71 of this swash shape and length direction, width are all not parallel.
Owing to apply power from inboard, lateral, width both sides, therefore surface sheet 3 easily taking place from the position that absorber 4 breaks away from, is assumed to be on the imaginary line L-1 and the imaginary line L-3 among Fig. 7 in Fig. 3 on sanitary napkin 1.In first embodiment shown in Figure 3, the waveform axle L-2 of the swash that ditch 31 forms is parallel with width.In this case, the summit of waveform regularly in a plurality of positions (being a, b, c position in illustrated example) and imaginary line L-1 tangent, therefore form the folding line of linearity imagination as binding this point of contact a, b, the c.Compare with prior art (patent documentation 2 disclosed surface sheets), although the danger that breaks away from is greatly diminished, but might occur by the folding line that above-mentioned point of contact a, b, c form is starting point, produces the situation that the such surface sheet of Figure 12 (C) breaks away from from absorber, therefore haves much room for improvement.
In second embodiment shown in Figure 7, because imaginary line L-3 and waveform axle L-4 out of plumb each other, so the summit of the waveform that forms of ditch 71 is not the point tangent with imaginary line L-3, so can not produce the problems referred to above.
The 3rd embodiment
Fig. 8 represents the vertical view of the 3rd embodiment of the sanitary napkin 1 that the present invention relates to.The ditch 81 formed wave-like lines of paying surface sheet 3 surfaces can not have curve, only otherwise have the part parallel with length direction with width, then can be the wave-like lines that is formed by triangular wave, square wave, the such straight line of sawtooth waveforms.
The 4th embodiment
Fig. 9 represents the vertical view of the 4th embodiment of the sanitary napkin 1 that the present invention relates to.As shown in Figure 9, the ditch 91 on surface sheet 3 surfaces can not be the ditch that is formed by successive wire recess, but is linked to be the ditch of wire by point-like recess 92.Main points are spaced apart below the 2.5mm length direction, and then formed ditch is successive, similarly reduce the danger of side leakage in the time of therefore can be with the recess of wire.In addition, compare,, yet in recess, have noncontinuity, so liquid is difficult to can reduce the danger of rear portion seepage along the recess diffusion though ditch is successive with situation with successive wire recess.
Though for the shape particular determination not of point, yet be preferably, the length of its length direction and width is 1.5～3.0mm, is preferably 2.0mm～2.5mm especially.Point is preferably below the 2.5mm at the interval of length direction, is preferably below the 1.5mm especially.Point is preferably below the 6.0mm at the interval of width, is preferably below the 3.5mm especially.When the interval of point is wide, then can damage preventing owing to forming the function that ditch breaks away from surface sheet 3.
The 5th embodiment
Figure 10 is the vertical view of the 5th embodiment of the sanitary napkin 1 that the present invention relates to of expression.As shown in figure 10, the rugosity of the wave-like line that is formed by the ditch 101 on surface sheet 3 surfaces (more preferably can be different in the scope of 2.0mm～2.5mm) at 1.5～3.0mm.In addition, can have the above interrupted part of 2.5mm in the longitudinal direction.Here, when the ditch part that will not have the interrupted part more than the 2.5mm as portion 102 continuously, with the interrupted part more than the 2.5mm during as discontinuities 103, the length of the length direction of discontinuities 103 then, be preferably continuous portion 102 length direction length 13% with interior and be no more than 5.0mm.In illustrated example, the continuous portion 102 of ditch 101 is formed by the point-like recess 104 of multiple size, yet also can be formed by successive line.The interval of some width is preferably below the 6.0mm, is preferably below the 3.5mm especially.
Same with the 4th embodiment, because recess is discrete, therefore can reduce the danger of rear portion seepage.In addition, by discontinuities 103 is set, thereby can improve the danger that above-mentioned noncontinuity further reduces the rear portion seepage.
The 6th embodiment
Figure 11 represents the vertical view of the 6th embodiment of the sanitary napkin 1 that the present invention relates to.When wearing, apply from the width both sides outsides under the effect of the power of inboard, the surface sheet position of easy disengaging is row's blood mouth abutting part.Therefore, the only row's of being configured in blood mouth abutment portion and periphery thereof of the ditch 111 on surface sheet 3 surfaces.In illustrated example, the pattern that is formed at the wave-like line of ditch 111 only is configured in the part of being surrounded by fit embossing 10, it is central authorities that but the pattern of this wave-like line needs only with row's blood mouth abutment portion, and on the width for more than the 40mm, be that the scope of 50～120mm get final product in the longitudinal direction, have nothing to do with position, the shape of pattern applying portion.
