Description
Technical field
The present invention relates to a kind of pieces, utilize the lenticular wire doubling and plant hair is planted hair side to head the lenticular wire hair-planted type toothbrush in the pore of planting many bristles binding bunchys.
Background technology
Toothbrush is in the past considered production efficiency or is planted the easy degree that hair is made, plant the planting in the pore of forming at interval that separate more than the 1.0mm on the hair side at toothbrush head, will with in average each hole 16～60, to become 32～120, bristle cross-sectional area summation be 1.0mm by folding
2Above mode makes the coarse wool bundle of bristle bunchy, utilizes lenticular wire to squeeze into and fix.Under the situation of such toothbrush, because pieces is thick and rigidity is high, so, have even surface or occlusal tartar and remove the extra high feature of power.
But, because of pieces thick, the bristle that constitutes pieces can support each other, can not bring into play the bristle monomer intrinsic soft effect, for between neck portion or tooth between portion, tooth the mouth disease of triangle etc. easily send out the narrow positions of portion, high-quality green tea is difficult to arrive, and hard because pieces is thick, has brought the problem too big to soft tissue irritation such as gums.
In addition, up to now, about head or handle portion, though by its shape, material, color etc. are studied, can realize differentiation between the product, but, for planting a mao portion, the rugosity of pieces or interval almost are similar styles entirely then, and the appearance poor opposite sex is low, as toothbrush, lack novelty.
The lenticular wire of lenticular wire hair-planted type toothbrush adopts slightly greater than the long size of planting pore dia, squeezes into when planting pore, in the head resin of its two end portions embedded hole periphery, whereby, with the pieces doubling, and is fixed on and plants in the pore.Like this, pieces can not extracted from plant pore, can be fixed on the planting on the hair side of head.Usually, lenticular wire length is 1.9mm～2.3mm, up and down width, be that the width of depth of drive direction is 1.3mm～2.0mm, thickness is about 0.25mm, generally is brass as material.
Plant at lenticular wire under the situation of toothbrush of hair, owing to be that thin-walled is planted pore, so the interval of adjacent pieces narrows down, lenticular wire is intensive, when lenticular wire squeeze into the direction unanimity, point-blank the time, the head resin between the adjacent lenticular wire can produce be full of cracks or whiting to lenticular wire side by side, produce bending because the stress deformation when lenticular wire is squeezed into causes at head, existed the anxiety of damage toothbrush outward appearance.In addition, produce under the situation of slight crack or crackle at head when planting mao, can cause the decline of finished product rate, production efficiency has also been brought negative effect.In addition, the fatigue of material production can cause problems such as losing of head when using because of long term, in the process of brushing teeth, under the situation that toothbrush damages, exists the danger that might injure finger or inside, oral cavity.
In order to prevent that this type of thing from taking place, and proposes following technical scheme: the thickness of having stipulated relative head is from planting the pore bottom surface length ratio below the portion (with reference to patent documentation 1: the spy opens flat 8-19423 communique) to the end; Lenticular wire squeezed into angle research (with reference to patent documentation 2: the spy opens flat 2001-314231 communique); The pieces of lenticular wire being planted hair is alternately arranged (with reference to patent documentation 3: the spy opens flat 2002-360343 communique) mutually with the pieces that hair is planted in adhesion; Lenticular wire planting of the most approaching part form protrusion (with reference to patent documentation 4: the spy opens flat 10-257922 communique) etc. on the hair side.
On the other hand, in order to prevent periodontal disease and to decay tooth two big dental disorders, remove the denude particular importance, so, but hope can obtain each corner in a kind of outwash oral cavity, the effect of removing the tartar that mouth disease easily sends out the position is good, damage tooth, the sense of touch toothbrush of brushing teeth well not.
In general, in the toothbrush of lenticular wire hair-planted type, when the pieces number of planting hair tailed off, it is big that pieces becomes at interval, can not fully remove denude, on the contrary, the pieces number for a long time, pieces narrows down at interval, is an impediment to the soft effect of pieces, has reduced the entering between tooth sharp.In addition, under the thick situation of pieces, the rigidity of pieces is too high, and not only portion or tiny gap enter difficulty between tooth, and have increased the harmfulness to tooth or gum.On the contrary, when pieces attenuated, hair bar weakened had not only reduced and has scrubbed true feeling, has reduced and has removed the ability that decayed tooth is easily sent out the tartar at position, has also reduced the durability of toothbrush.Therefore, in the past, the pieces number that will plant on the gross area according to per unit with the pieces that the rugosity of the about 1.6～2.0mm degree of diameter is formed was 20 bundle/cm
2About plant hair.
Given this, following toothbrush has been proposed: good as sense of touch, the toothbrush in each corner in the energy outwash oral cavity, careful ground, employing is planted the toothbrush of hair (with reference to patent documentation 5: the flat 11-500946 communique of special table with the few and thin pieces of bristle radical, patent documentation 6: the spy opens the 2000-342334 communique) or the pieces diameter of brush length direction done weak point, the toothbrush of suitably regulating the power of scrubbing of pieces is (with reference to patent documentation 7: No. 2549935 communique of the utility model of registration, patent documentation 8: the spy opens flat 10-327930 communique, patent documentation 9: the spy opens flat 10-327931 communique) etc.
In recent years, also disclose and looked like the such toothbrush of planting pore for a short time of electric toothbrush with 1.0mm degree.Electric toothbrush since its to plant mao frame little, so the style that the diameter that dwindles pieces is planted hair has as much as possible carried out inquiring into (with reference to patent documentation 10: the flat 11-508168 communique of special table).
In addition,, the strong desire in intraoral each corner such as outwash molar is arranged along with the raising of the consciousness of oral hygiene in recent years, therefore, the toothbrush that has also proposed to utilize polyacetals to realize the thin-walled property of head (with reference to patent documentation 11: the spy opens flat 7-143914 communique) etc.

Toothbrush in the past, though that thick, the occlusal tartar of pieces is removed power is also strong,, between neck portion or tooth between portion, tooth mouth disease such as triangle easily send out the position, high-quality green tea may not necessarily arrive.Given this, though by the fine, soft fur bundle is implanted with high density, attempting addressing these problems,, relevant only pieces rugosity or opinion at interval, rarely known by the people.
In addition, by implanting pieces, can bring problems such as lenticular wire narrows down at interval, head produces be full of cracks or whiten, bend with high density.On the other hand, with prevent to chap or whiten occur as purpose, shorten under the situation of lenticular wire, can produce the come off problem of intensity reduction etc. of pieces intensity or hair.
As described above, for the generation that prevents to chap or whiten and the bending of head etc., though various toothbrushes have been proposed,, because be subjected to nose shape, plant the pore shape, the restriction of lenticular wire angle etc., may not necessarily be applied to as in the purpose toothbrush.
Solution as be full of cracks or whiting, though methods such as the interval that enlarges between the pieces, change resin kind are arranged, but, when enlarging the pieces interval, be difficult to obtain sufficient function as toothbrush,, also will consider the anti-medicine or the price of head even change resin, in this case, be difficult to obtain wise multinomial selection.
On the other hand, basic function as toothbrush, require to obtain to clean intraoral each corner consumingly and can damage not arranged or gum is not had harm, toothbrush that sense of touch is good tooth, in order to realize this purpose, plant the method for hair or with the method for head thickness skiving though can adopt the pieces of few radical bristle being formed with high density, but, still leave when the planting mao head resin between the adjacent lenticular wire and can produce be full of cracks or whiting or head and produce bending etc. and need the problem that solves.
Summary of the invention
The present invention proposes in order to address the above problem, and its objective is, when providing one kind to plant mao head do not chap or whiten, crooked, lenticular wire does not come off etc. the high-quality toothbrush of planting mao bad phenomenon.
Further, a further object of the present invention is, a kind of lenticular wire hair-planted type toothbrush of the pieces high density being planted hair is provided, and when providing one kind to plant mao head do not chap or whiten, crooked, lenticular wire does not come off etc. plants a mao bad phenomenon, and, be soft, good to the sense of touch of soft tissue in tooth or the oral cavity, to the good high-quality toothbrush of the entering of slight gap.
To achieve these goals, the toothbrush of technical scheme 1 is with the pieces with many bristle bundle bunchys, utilizes the lenticular wire doubling and plants hair and plant planting in the pore of hair side to head, it is characterized in that the thickness of above-mentioned lenticular wire is above, the not enough 0.22mm of 0.10mm.
The toothbrush of technical scheme 2 is in technical scheme 1, and the width of above-mentioned lenticular wire is more than the 0.9mm, below the 2.5mm.
The toothbrush of technical scheme 3 is in technical scheme 1 or 2, and above-mentioned pieces per unit of planting hair is planted number on the gross area at 25 bundle/cm
2More than, 80 bundle/cm
2Below, planting hair is 1.0mm in the summation of the cross-sectional area of bristle under folded state in per 1 hole of planting pore
2Below.
In addition, so-called per unit is planted the pieces number on the gross area, is meant with planting hair to plant the sum (=plant pore sum) of the pieces of hair side divided by planting gross area (cm in head
2) resulting value.In addition, what is called is planted gross area and is based on that the regulation of JIS S3016 obtains, shown in Fig. 1 (a), be meant with and come the area S (part that dotted line was surrounded) that plants the part inboard that the outside of planting pore 3 on hair side 2 peripheries connects with straight line of head 1.
The toothbrush of technical scheme 4 is in technical scheme 1 or 2, and above-mentioned head is formed from a resin, and on above-mentioned at least a portion of planting pore, the summation that constitutes the bristle cross-sectional area that plants the pieces in planting pore is at 1.0mm
2Below, simultaneously, any one plants being made as below the 1.0mm with the immediate distance that another plants pore of pore at least.
As toothbrush of the present invention, with lenticular wire fixedly under the situation of pieces,, on resin, produce stress because lenticular wire can destroy near the resin of planting the pore when squeezing into.In the past, though the thickness of the lenticular wire that uses is more than the 0.25mm degree, but, because planting pore or per unit at thin-walled plants under the many situations of pieces number on the gross area, lenticular wire is intensive, so,, can on the head resin between the adjacent lenticular wire, generation chap or whiten planting the pore bigger stress of resin generation on every side.In addition, even lenticular wire side by side point-blank, also can produce be full of cracks or whiting.
If when using the lenticular wire of the above thickness of 0.25mm degree, be easy to take place head-bent or whiting, be full of cracks etc.For example, with the bending strength 600kg/cm
2More than, 750kg/cm
2Below hard being difficult under the situation that crooked resin uses as the head material, when the lenticular wire of used thickness 0.25mm is planted mao, also can produce crooked at head.Given this, it is the lenticular wire of 0.10～0.22mm when planting mao that the present invention adopts thickness, can reduce the bending of head, has almost eliminated all problems in the actual use.
On the other hand, be 150kg/cm with the resin bending strength
2More than, 600kg/cm
2Under the situation of the vistanex that relatively is easy to crooked resin, for example polypropylene etc. as the use of head material of following softness, if used thickness is the lenticular wire of 0.25mm, because head produces crooked greatly, plants pore and misplaces from the normal position, lenticular wire can not be squeezed into continuously.Given this, when adopting thickness to be the lenticular wire of 0.10～0.22mm among the present invention, head almost be can't see bending when planting mao, also can successfully carry out squeezing into of lenticular wire.Like this, the bending strength at vistanex and so on is 150kg/cm
2More than, 600kg/cm
2Under the following situation that relatively is easy to crooked resin, can see, utilize the particular significant effect of the minimizing bending that the thin-walled property of lenticular wire produces.In addition, so-called here bending strength is based on the value that JIS K6758 measures.
In addition, clearly, during lenticular wire thickness is not enough 0.10mm, the rigidity deficiency of head resin, lenticular wire produces distortion when planting mao, plants hair self difficulty.
Further,, wish that head thickness is more thinner, still,, can reduce intraoral operability when the thickness of head during greater than 5.0mm in order to improve intraoral operability.Under the thin situation of head, though can improve operability,, support the amount of resin of pieces to reduce, will inevitably reduce the intensity of head, when utilizing the lenticular wire of normal thickness, exist the situation that may produce bending, crackle, whiting etc.In addition, head is crossed when approaching, and plants pore and shoals, and plants the hair difficulty.Given this, under head thickness is situation more than the 2.5mm, below the 5.0mm, when utilizing the lenticular wire of all thickness to plant the hair experiment, can draw, if utilize thickness more than the 0.10mm, not enough 0.22mm, be preferably in more than the 0.13mm, the lenticular wire of not enough 0.22mm thickness, then be difficult to produce bending or be full of cracks, whiting etc.
The present invention is based on above-mentioned various experimental result, with the thickness of lenticular wire be made as more than the 0.10mm, not enough 0.22mm, be preferably in that 0.13mm is above, not enough 0.22mm.
The width of the depth direction of squeezing into about lenticular wire when increasing width, owing to increased the contact area of the relative head resin of lenticular wire, under the prerequisite that does not increase lenticular wire interlock amount, can improve and plant a mao intensity.Therefore, be under the relatively more soft situation of planting the low resin of mao intensity such as acrylic resin (PP) in the head material, it is effective that the width that increases lenticular wire is as much as possible planted mao intensity to raising.But, showing that according to present inventor's experiment under the situation of lenticular wire width greater than 2.5mm, lenticular wire can be outstanding to the outside from planting hair side, most advanced and sophisticated from the head side is observed when planting hair side, can see lenticular wire, can bring inaesthetic in appearance result.
On the other hand, in the head material is that (for example the many ethene of poly that become of acid are to benzene polymer (PCTA for polyacetal resin (POM) or saturated polyester resin, polycyclohexylenedimethylene terephthalate copolymer), the many ethene of poly that become of ethylene glycol are to benzene polymer (PCTG), polycyclohexylenedimethylenecopolymer) etc. under the harder situation of planting the high resin of mao intensity, even the lenticular wire width is little, also can be planted a mao intensity fully.Therefore, if the lenticular wire width is little, to plant the pore degree of depth also shallow, then can be with the thickness attenuation of head, and also can improve operability.But, when the lenticular wire width too hour, can reduce and plant a mao intensity, produce the problem in the practicality.According to experiment of the present invention, can draw, when the lenticular wire width is discontented with 0.9mm, can reduces significantly and plant a mao intensity.Given this, in the present invention, with the width of lenticular wire be made as more than the 0.9mm, below the 2.5mm.
Usually, under the situation of the toothbrush of lenticular wire hair-planted type, though per unit is planted pieces number on the gross area at 20 bundle/cm
2About, the summation of bristle cross-sectional area is at 1.1～2.5mm
2Degree, still,, can draw, if per unit is planted pieces number on the gross area at 25 bundle/cm according to experiment of the present invention
2More than, 80 bundle/cm
2Below, and plant hair in the summation of the cross-sectional area of bristle under folded state in per 1 hole of planting pore at 1.0mm
2Below, then can obtain the performance good to the sense of touch of tooth or gum, to remove function also good for entering or tartar between tooth.
Though the summation of planting the bristle cross-sectional area of hair under 1 folded state of planting in the pore is at 1.0mm
2Below relatively good, still, be preferably in 0.10～0.70mm
2Scope.At this moment, when for example getting the bristle section configuration and be circular situation, use in the hair at 7mil (0.178mm), there are general 5～14 in per 1 hole, be equivalent to be folded into 10～28, but this is the standard in the design, and these radicals can be set arbitrarily according to toothbrush style and bristle diameter, section configuration etc. in the design.
In the summation of the cross-sectional area of bristle under folded state of planting per 1 hole of hair in planting pore greater than 1.0mm
2Situation under, pieces loses flexibility, pieces worsens to the attainability of slight gap, can not realize fully in the outwash oral cavity.In addition, though the summation of bristle cross-sectional area at 1.0mm
2Below, plant pieces number on the gross area greater than 80 bundle/cm in per unit
2Situation under, it is very narrow that the gap between the pieces becomes, and not only causes the entering deterioration between tooth, the scope that pieces moves freely also is restricted, therefore, the fine cleaning of scrubbing the position such as neck portion is very difficult.In addition, toothpaste remains between the pieces, the extreme deterioration of drying property after also having caused using etc., and also the health aspect also becomes big problem.In addition, though the summation of bristle cross-sectional area at 1.0mm
2Below, the pieces number of planting on the gross area in per unit is less than 25 bundle/cm
2Situation under, not only ugly especially in appearance, and the portion's weakened of arching one's back, the cleaning of the flank of tooth be difficulty also, has also reduced the durability of toothbrush.
In addition, under the situation of pieces being planted hair with the flat wire type feather planting machine, in the assistor of flat wire type feather planting machine, when the pieces of doubling returns linearity, produce restoring force, can apply big counter-force lenticular wire.According to experiment of the present invention, be that (cross-sectional area is 2.0～3.1cm to 1.6～2.0mm at diameter
3) the situation of pieces under, though being the lenticular wire about 0.25mm, common used thickness squeezes into pieces, but, thickness of the present invention is that 0.10mm is above, under the situation of the slim lenticular wire of not enough 0.22mm, lenticular wire can not bear the restoring force of pieces, lenticular wire outwards comes off, staggers etc. from pieces, exists the bad very high situation of incidence of hair of planting.In this case, draw: by with hard metals such as lenticular wire material use stainless steels, can improve the rigidity of slim lenticular wire, reduce and plant the bad incidence of hair.
On the other hand, the present inventor to pursue the result under the condition of the pieces rugosity that satisfies the requirement scrub performance and slim lenticular wire two aspects be that the summation of the bristle cross-sectional area under the employing folded state is 1.0mm
2Below, 0.1mm preferably
2More than, 0.7mm
2Following pieces like this, is planted the toothbrush of hair as high density, when can obtain keeping high scrubbability, can fully bear the toothbrush of the pieces restoring force when planting mao.
In addition, any one is planted the distance (planting the distance between the pore recently) that another plants pore pore and immediate to be made as 1.0mm following relatively good at least, is preferably in the scope that 0.25mm is above, 0.75mm is following.When pieces was narrow at interval, bristle can not enter between tooth, entered performance thereby reduce between tooth.On the other hand, when excessive at interval, reduced the appearance poor opposite sex and scrubbed true feeling.In addition, when at interval excessive, along with the motion of brushing teeth, the reaction force grow of pieces increases when scrubbing not sensation of softness of pieces, not only reduces usability, can not bring into play 11 smooth motion of bristle, has also reduced the tartar removal effect.
Plant in mao toothbrush at the lenticular wire of main flow in the past, in order to ensure mao intensity of planting of JIS standard code, the circular cross section that uses diameter 1.5～2.2mm degree plant pore in, the interlock amount of planting the pore peritreme as lenticular wire relatively is set in about 0.25mm.Even in having the few toothbrush of planting pore of a plurality of pieces, by increasing lenticular wire thickness or interlock amount, also can guarantee mao intensity of planting in a way, still, because be full of cracks or whiting are restricted.
Given this, the present inventor experimentizes with keen determination, studies, the result who obtains is, in few the planting in the hair of pieces, plant mao intensity and do not rely on activity coefficient PF=(summation of bristle cross-sectional area)/(planting the shared cross-sectional area of planting pore of pore area-lenticular wire) * 100% (density of planting pore in average relatively 1 hole of=pieces), the length of lenticular wire, the kind of handle resin, but substantial connection is arranged with volume (resin destruction volume) that lenticular wire destroys the handle resin.And further the result who inquires into repeatedly shows, the scope that only resin destroys volume is 0.1～0.4mm
3Scope, be preferably in 0.15～0.3mm
3Scope.Not enough 0.1mm
3The time, as toothbrush, can not get mao intensity of planting of necessary rerum natura, in addition, surpassing 0.4mm
3Situation under, problems such as head-bent or the whiting of head resin can take place.
As the material of the toothbrush handle that comprises head, polystyrene resin (PS), acrylic resin (PP), PETG (PET), acrylonitrile-butadiene-styrene resin (ABS), cellulose propionate resin (CP), polyaryl resin, polycarbonate resin (PC), saturated polyester resin (PCTA, PCTG etc.), acrylonitrile-styrene resin (AS), polyacetals (POM), polybutylene terephthalate (PBT) materials such as (PBT) can be used alone or as a mixture.In addition, can also be the polychrome shaping handle of combination such as thermoplastic elastomer.In addition, grip material is not limited in the above-mentioned resin.In addition, be not subjected to any restriction as comprising shape, size or the design of head in interior toothbrush handle yet.
The material of lenticular wire, preferably metal such as the good brass of intensity or stainless steel.In addition, also can use with the Biodegradable plastics and be rigid plastics of representative etc.Can also on the outer surface of lenticular wire, squeeze into direction with relative lenticular wire and vertically offer groove, improve with this and plant a mao intensity.
As described above, though the lenticular wire about the about 0.25mm of used thickness in the ordinary toothbrush,, in the past, as metal lenticular wire, manufacture more thinner than this lenticular wire, this be technically very the difficulty.In other words, produce lenticular wire though the metal wire that is called round line can be prolonged with roll-in,, usually, when slightly round line heats in stove, in the primary stage, this thick circle line is extended into thin round line, owing to be used for the round line of slim lenticular wire, thinner than common round line, therefore, with an operation, be difficult to obtain even fineness degree.
But, recently,, extension process is divided into a plurality of stages by improving the manufacturing technology of lenticular wire, little by little extend, needing can obtain the round line of fineness degree.Further, strong excessively with the power of the roller clamping circle line of normal size when calendering circle line, can produce the improper phenomenon of planting the bad reason of hair that becomes that lenticular wire plays wave etc., and, roll with suitable extruding force by dwindling roller diameter, can produce slim lenticular wire.As a result, can produce be used for of the present invention, thickness more than the 0.10mm, not enough 0.22mm, width be at the slim lenticular wire more than the 0.9mm, below the 2.5mm.
Because the thickness of lenticular wire is directly relevant with the head resin volume that lenticular wire destroys with length, therefore, be preferably based on and the relation of the shape of planting pore with the lenticular wire interlock amount, lenticular wire depth of drive etc. of size, relative peritreme, and according to making above-mentioned resin destruction volume at 0.1mm
3More than, 0.4mm
3Following mode is set thickness and length.
It is proper to plant regular polygons such as common circle of being shaped as of pore or square, still, also can be ellipse, gold coin shape, rectangle etc., can also be the shape with major diameter (long limit) and minor axis (minor face).In addition, by combination bore towards, can obtain being adapted to as entering, hair between the tooth of purpose sense of touch, scrub the style of the requirement of true feeling.In addition, under the situation of planting pore with major diameter (long limit) and minor axis (minor face), during with the parallel arrangement arranged side by side of minor axis (minor face) with external edge of head, when observing head from the side, can see narrow minor axis (minor face) side of pieces width of planting hair, compare with the circular pieces that identical bristle radical is formed, seem thinner, can improve the appearance poor opposite sex.
Though planting the hole configuration of pore generally is the clathrate configuration,, for fear of the interference each other of adjacent lenticular wire, realize the configuration of highdensity hole, also can arrange with zigzag.In addition, different according to circumstances, by changing the direction of squeezing into of lenticular wire, also can make the outermost pieces of head seem thinner, can improve the appearance poor opposite sex.
Planting pore major diameter direction when squeezing into lenticular wire, make bristle arranged side by side along lenticular wire, can improve and plant a mao intensity.At this moment plant the pore shape, in order to reduce pieces and to plant gap between the pore, rectangle roughly preferably.In addition, consistent by the circumcircle minor axis direction that makes relative pieces section when the minor axis direction is squeezed into lenticular wire with the minor axis direction of planting pore, can reduce the gap of planting between pore and the pieces, produce mao portion of planting of mao upright function admirable.At this moment, under the situation of bristle section as circle of using, the shape of planting pore preferably is roughly ellipse, is roughly Long Circle.
Material as the bristle (filament) that constitutes pieces, the raw material that preferably utilize polyolefin such as PETG (PET), polybutylene terephthalate (PBT) (PBT), poly-polyamide, polystyrene, polypropylene and gather many ethylene halides such as fluoridizing Vingon etc., melt spinning to this dioctyl phthalate propylene diester (PTT) polyester of etc.ing, nylon 6-10, nylon 6-12, nylon 12 etc., but, from aspects such as usability, durability, preferably, nylon, polytrimethylene terephthalate.In addition, make the bristle of dual cored structure, can make inboard not on an equal basis, also can look purpose and make up with outside material or surface state with these resins.
The rugosity of bristle is 3～10mil (0.076～0.254mm), be preferably 5～8mil (0.125～0.203mm), consider usability, scrub the factor of true feeling, cleaning effect, durability etc., in these scopes, preferably that rugosity is different bristle combinations are used.Particularly, planting the situation that pore is configured to highdensity style with a plurality of, higher from outside pieces towards the arch one's back intensity of portion of the bristle of the pieces of central authorities; Perhaps the change of the rugosity of bristle, material, length, color, section configuration etc. is favourable for the usability or the appearance poor opposite sex.
