Concrete form of implementation
Following reference is elaborated to liquid permeability surface patch of the present invention as the example and the accompanying drawing of the sanitary napkin of body fluid absorbent article.
Sanitary napkin 1 among Fig. 1 shown in the broken section oblique view is made with vertical A and horizontal B, and the long rectangle of vertical A, and it is formed by liquid permeability surface patch 2, opaque liquid inner surface sheet 3 and absorbency core material 4.Surface patch 2 and inner surface sheet 3, are connected together by clinkering or agglutinating mode towards extending laterally and overlapping mutually from the periphery of core material 4, form a pair of side portion 6 of extending towards vertical A and a pair of edge part 7 that extends towards horizontal B.
Core material 4 is the paper pulp that will pulverize, or the paper pulp of pulverizing is compressed to desired density with the particulate mixture of superabsorbent polymer, the paper pulp of pulverizing and the mixture of superabsorbent polymer fiber etc. and forms, and uses thin paper 14 with its whole coatings therefore usually.Core material 4 is fitted on inner surface sheet 3 and/or the surface patch 2 by the binding agent of hot-melt adhesive etc.
Fig. 2 is that the part of surface patch 2 enlarges oblique view.Surface patch 2 has the flat condition of forming, be used for the proximate skin contact area 21 of sanitary towel's user skin and formed a plurality of open-works 22 at edge by skin contact area 21.Skin contact area 21 has and sanitary towel's user skin upper surface 23 in opposite directions and the lower surface 24 that is positioned at upper surface 23 inboards, and the thickness t between these two surfaces 23,24 is preferably in the scope of 0.01～0.05mm.The width w of the skin contact area 21 between the adjacent open- work 22 and 22 is preferably in the scope of 0.1～1mm.Open-work 22 has by skin contact area 21 and forms the top peristome 26 at edge, is the tube 27 that extends to lower surface 24 of the upper surface 23 of skin contact area 21 and the lower opening portion 29 that formed by the end portion 28 of tube 27 from peristome 26.Being shaped as of top peristome 26 is atypic, except the difference as example among the figure probably is the situation of circle, and all right independent assortment Long Circle, polygon and other arbitrary shape.Tube 27 from top peristome 26 downwards the direction internal diameter of peristome 29 reduce gradually.The end portion 28 of tube 27 is irregular on peripheral direction, and by the many places refinement.This end portion 28 in the tube 27 more the part of top be crooked, and extend towards the radially inner side of tube 27.
Fig. 3,4 is the sectional view along the III-III line of Fig. 2, and this sectional view IV-IV line to view, but Fig. 3 has only shown the part of core material 4.From these figure as can be known, the internal diameter of tube 27 diminishes to the direction of lower surface 24 gradually from the upper surface 23 of skin contact area 21, but end portion 28 for its more the part of top be crooked, and be vase-like towards the radially inner side of tube 27 and extend.In the open-work 22 that comprises this tube 27, plastic sheeting 27 marks smooth arc shape and extends from skin contact area 21 towards tube.In tube 27, the thickness of this plastic sheeting from top peristome 26 downwards peristome 29 reduce gradually.The end portion 28 that roughly will form lower opening portion 29 peripheral parts to the many places breach 31 that radially extends to form by lower opening portion 29 is cut apart on peripheral direction and by the many places refinement.At its end portion 28 places, the upper surface 23 of plastic sheeting is to make progress with top peristome 26 mode in opposite directions, and lower surface 24 joins from the thin paper 14 of top and core material 4.Open-work 22 still owing to there is breach 31, can suppress this tendency because end portion 28 extends towards radially inner side, and the aperture area of its lower opening portion 29 has the tendency that diminishes.Tube 27 preferably has almost consistent 30～80 ° for the horizontal plane L shown in the thin paper 14, more preferably 40～75 ° inclination angle.In Fig. 4, with the maximum diameter d of the lower opening portion 29 shown in the imaginary line m that connects in tube 27 end portions 28 in the scope of 0.3～2mm.The degree of depth n of preferred tube 27 from the upper surface 23 of skin contact area 21 to lower opening portion 29 is in the scope of 0.1～2mm.
For the plastic sheeting that forms this surface patch 2 usefulness, the preferred use has 10～50g/m
2The thin film that the polyolefin polymers of weight per unit area forms.In this polymer, comprise the mixture of Natene or copolymer and these homopolymer or copolymer.The example of a particularly preferred plastic sheeting is as follows: in the thin film of 100 weight %, the micropartical material that contains the barium sulfate, calcium carbonate, Talcum etc. of the copolymer of alpha-olefin of the ethylene of low density polyethylene (LDPE), 25～40 weight % of linear low density polyethylene, 0～10 weight % of 25～40 weight % and butylene, propylene, 4-methylpentene, octene etc. and 20～50 weight % contains the lubriation material of the hydrophilizing agent, fatty acid amide etc. of the coloring agent such as titanium oxide of approrpiate wts %, the fatty acid ester of glycerol etc. in addition.In this thin-film examples, the copolymer of ethylene and alpha-olefin can be given thin flexible film ductility.The micropartical of barium sulfate etc. is appeared in one's mind from the surface when extension film, can eliminate the gloss on surface, and suppress the being clamminess property of this surface to skin.Coloring agent such as titanium oxide can be hidden the menses that core material 4 is absorbed.By using hydrophilizing agent, can give tube 27 upper surfaces 23 hydrophilic, the menses that flow into tube 27 can be shifted to core material 4 by intensive capillarity.
In the sanitary napkin that forms thus, after absorbing menses, when the side is observed from it, the menses that absorbed by core material 4 by tube 27 below peristome 29 places can directly see, and at many places breach 31 places that form lower opening portion 29 and tube 27 end portions 28 boundaries, the painted end portion 28 that exists between the breach 31 and 31 can stop the direct-view to menses, and it is not obvious that menses become.During the plastic sheeting that is creamy white use adopting titanium oxide, below peristome 29 around can find that menses are by whitening.This sanitary napkin 1 can not make the aperture area of tube 27 lower opening portions 29 significantly reduce, and in other words, does not sacrifice the infiltration rate and the absorbtivity of sanitary towel 1, and is difficult to look at straight the menses that absorbed by core material 4.
Fig. 5 is for showing an accompanying drawing form of implementation example, the same with Fig. 2.That the surface patch 2 of legend has is parallel to each other on the upper surface 23 of skin contact area 21, along many projectioies 51 of the 1 vertical A of sanitary towel.Projection 51 top 52 is not stimulate skin, preferably makes top 52 be suitable circular-arc.Projection 51 height in 0.5～2 times scope of the thickness t of skin contact area 21, adjacent protrusion 51 each other apart from size p in the scope of 2～8mm.When this projection 51 contacts with skin in sanitary towel 1, can prevent that skin contact area 21 from fitting with skin in large area,, can prevent that skin is sultry by between skin contact area 21 and skin, forming the gap that to ventilate.In addition, to the contacted diaper 1 of width B compression and skin the time, but the wrinkle that produces on the projection 51 qualified list dough sheets 2 extends to vertical A.By the wrinkle that produces on the surface patch 2 is extended to vertical A, can suppress menses and flow to width B, make diaper 1 be difficult to transverse leakage thus.In addition, at these 2 places, surface, owing to tend to reduce with the contact area of skin, at vertical A of diaper 1 with laterally the sliding between B direction upper surface sheet 2 and the skin is all very good, so surface patch 2 also reduces for the being clamminess property of skin.
Fig. 6 shows an accompanying drawing form of implementation example, the same with Fig. 5.In the surface patch 2 of legend, skin contact area 21 local upwards protuberances form projection 51.This ridge 51 has the effect the same with ridge shown in Figure 5, but when push from the top, than ridge shown in Figure 5 easy deformation more, so soft feel when contacting with skin.
The invention effect
Surface patch of the present invention has the liquid permeability open-work, and in this open-work, the end portion of tube is four Zhou Fangxiang is upper by the many places refinement, and to the radially inner side bending of tube, therefore by tube by core The body fluid that material absorbs, for example menses only can directly be seen in the lower opening section of open-work, and are opened by the below The tube end portion in the oral area outside is hidden, becomes not obvious. Use at the physiology that will have this surface patch When the body fluid absorbent article of sanitary napkin etc. is discarded, can relax owing to directly see the pollution that is caused by body fluid And the unplessantness displeasure that produces.
