Description
Technical field
The present invention relates to softness and contiguous sense good, can access the toothbrush that higher sweeping efficient and massage feeling and good tartar are removed treatment power, that be suitable as periodontosis and gingivitis or prevention usefulness.
Background technology
In the past as having softness and thinner toothbrush, the known toothbrush that use animal hair (pig hair, leopard cat hair, goats hair, their mixed hair) arranged with hair.It is that animal hair thick about about 1～8mil is pricked bundle and made pieces, so because be that natural hair has quality to be not so good as the stable problem of synthetic resin hair.
In addition, as the treatment of periodontosis and gingivitis or the toothbrush of prevention usefulness, the superfine hair of front end toothbrush is famous, but the cone-shaped that the superfine hair of this front end toothbrush is sharp-pointed owing to use the high-quality green tea parts of fine with hair, so under the more serious patient's of gingivitis situation, feel the pain that the stimulation of high-quality green tea brings sometimes.
Usually, the mechanical stimulus that sweeping causes in the treatment of periodontosis and prevention is effective, but in general toothbrush, use usefulness hair thick about 5～12mil, if suffer from the people of periodontosis use it could be hemorrhage or gum pain etc., the long-time sweeping so toothbrush just in time can not be contacted at affected part.
On the other hand, as the measure that improves sweeping efficient, up to the present also considered various means, one of them has larger-diameter employing of planting pore.Plant the diameter of pore by increase, increase constitute pieces with mao radical improve the rigidity of pieces, and the contact area of the increase and the flank of tooth improves sweeping efficient.But if increase the diameter of planting pore, the consume material of then locking parts (so-called horizontal line) diminishes with respect to the magnitude proportion of pieces, and mao problem of intensity step-down of planting is arranged.
Though increase consume material, improve that to plant mao intensity also be possible technically by the lengthening horizontal line, but preferably make close hair specification as far as possible in order to improve sweeping efficient, can bring head to plant the generation of breaking and whitening of hair side owing to squeeze into long horizontal line, so not preferred with close hair specification.
In patent documentation 1 (Japanese kokai publication hei 4-261605 communique), represented by improving the toothbrush of planting mao intensity and the bristle free end can not be enlarged with a hair filling rate (fill factor, curve factor), raising of planting pore inside with respect to planting sectional area that the pore peristome reduces hole depth bottom.But if excessively improve with a hair filling rate, then hair plantation needle fractures easily when planting mao, and breaking and the problem of whiting etc. of toothbrush head might be taken place.
On the other hand, in patent documentation 2 (the real public clear 63-95828 communique of Japan), a part of having represented bristle tuft is by the toothbrush that the mixing of coarse wool and fine, soft fur constitutes with pieces, also put down in writing in the pieces with the configuration of hair etc., but do not discuss with nominal diameter for only.Under the coarse wool and the inappropriate situation of fine, soft fur of combination, when sweeping the coarse wool effect remarkable, feel the pain that the stimulation of high-quality green tea brings sometimes, be unsuitable for having the user's of gingivitis situation in addition.
In patent documentation 3 (Japanese kokai publication hei 2-98310 communique), represented that front end has been made spherical mane (with hair) mixes the toothbrush of planting hair with the mane that the front end sphering is handled, but do not expressed especially for the mane diameter.This toothbrush is owing to doing glomeration with high-quality green tea, and is than big with wool base, also bad so contiguous sense is uneven.In addition, be difficult to the narrower gap of between cog etc. is cleaned effectively by more weak sweeping pressure.
In patent documentation 4 (Japanese kokai publication hei 6-141923 communique), represented that high-quality green tea is the synthetic resin yarn of cone-shaped, but this silk is because high-quality green tea is more sharp-pointed, so clean narrower gap easily, be suitable for the gum massage of appropriateness, but the situation of the puncture sense of the high-quality green tea of disliking sharpening is arranged according to the user.In addition, because that the height sharpening of high-quality green tea is processed into is expensive, so the problem that has toothbrush to become expensive.
In patent documentation 5 (Japan opens flat 5-68328 communique in fact), represented to form reducing diameter part, guarantee the higher toothbrush of planting mao intensity by partly improving by this reducing diameter part with a hair filling rate at the pars intermedia of the depth direction of planting pore.But under the situation of this toothbrush, it is complicated that the structure (the particularly structure of contact pin) of the metal pattern that uses when being shaped can become unavoidably, the measure that can not say so from the aspect of manufacturing cost and manufacturing technology.
In patent documentation 6 (Japanese kokai publication hei 8-19423 communique), represented still do not have enough discussion about the aperture of planting pore in order to make breaking and be out of shape and plant the higher toothbrush of mao intensity and the toothbrush having stipulated to plant mao abutment portion and planted the thickness between the pore bottom surface of the head that suppresses to plant in mao operation.

Toothbrush with the record of above-mentioned patent documentation is representative, under the situation of in the past toothbrush, following problem is arranged.
(1), needs contiguous sense toothbrush preferably soft and that can carry out the massage of gum, but fully do not satisfy the toothbrush of this point as the toothbrush of the treatment or the prevention that are used for carrying out periodontosis and gingivitis.
(2) need have higher tartar and remove power,,, but fully not satisfy the toothbrush of this point even make the people of gum pain such as gingivitis patients also can use even also can arrive intraoral each corner by more weak sweeping pressure.
(3) toothbrush of the hair intensity of the softness of in the past using generally by thin diameter with mao constituting bristle, and if a little less than mistake detailed rules and regulations hair intensity became, be difficult to obtain enough sweeping power.
(4), still having problems aspect the stabilisation of quality and the cost as using with hair intensity and mixes a toothbrush with the pieces that constitutes of hair by reducing and have and use natural mao toothbrush in order to take into account soft feeling.In addition, natural hair toothbrush is owing to be animal hair, thus have the water absorption of bristle more, compare problem poor slightly on the clean feel after the use with synthetic resin with a mao toothbrush.
(5) in general horizontal line formula feather planting machine, to grasp with hair with withdrawal device and a certain amount ofly to plant hair as pieces, but in the such reducing of natural hair toothbrush mixes with the hair toothbrush because multiple with mao being present in the pieces randomly, so each pieces might not with the hair root number.Therefore, the bristle intensity of product (hair intensity) management as common synthetic resin is counting this with hair root to substitute that characteristic value manages be very difficult by each hole with mao toothbrush, need be undertaken by destructive inspection measuring machines such as ring crusher or stretching-machines, qualitative control is difficulty.
(6) under the situation with hair in the thin footpath of use, plant mao intensity deficiency easily, when sweeping, come off the lifetime of toothbrush easily with hair.
Summary of the invention
The present invention makes in order to solve problem as described above, and the 1st purpose provides a kind of softness and contiguous sense is better, can access higher sweeping efficient and massage feeling and good tartar removes power, is suitable as severe or slight periodontosis, the treatment of gingivitis or the toothbrush of prevention usefulness.And then, the 2nd purpose provide one kind plant mao intensity higher and do not have that hair comes off, the breaking and whiten also less high-quality toothbrush of head.
To achieve these goals, technical scheme 1 described toothbrush, be synthetic resin is pricked bundle with hair and to make pieces, this pieces is planted the toothbrush in the pore of planting at head, it is characterized in that, making above-mentioned cross-sectional area of planting pore is the above circular port of diameter 1.8mm or the size of this circular port correspondence, and makes that to plant at this synthetic resin of planting in the pore be circle mao diameter 0.127mm (5mil) below or size that should circle hair correspondence with the cross-sectional area of hair.
In addition, so-called with hair filling rate (fill factor, curve factor), be establish by the cross-sectional area that deducts the horizontal line of squeezing into from the cross-sectional area of planting pore obtain actual to plant mao cross-sectional area be A, establish and plant hair and planting the summation of the cross-sectional area of the bristle the pore when being B, by (B/A) * 100[%] value that provides.
In addition, the so-called gross density of planting is by (plant the summation of pore sectional area/plant gross area) * 100[%] value that provides.In the formula, so-called " planting gross area " is meant will to be formed on that head plants that the outside of planting the pore group on the hair side links with straight line and the area (JIS S3016) in the zone that obtains.
Technical scheme 4 described toothbrushes, be in technical scheme 3 described toothbrushes, it is characterized in that, all plant that planting more than at least 5% in the pore plants the circular hair of diameter 0.127mm (5mil) in the pore or the synthetic resin that constitutes by the cross-sectional area of this circle hair correspondence with hair.
Technical scheme 6 described inventions are in technical scheme 1～5 described toothbrush, it is characterized in that making the adjacent the shortest distance between borehole of planting pore is 0.1～0.4mm.
1, with hair
As plant hair in planting pore with hair, use the following synthetic resin of diameter 0.127mm (5mil) with hair.If thicker than 0.127mm (5mil), then intensity became strong, and was really up to the mark for periodontosis patient or gingivitis patients, and pieces becomes not flexible, the thinner part of the difficult arrival of high-quality green tea.Under diameter is situation below the 0.127mm (5mil), softness and contiguous sense is good, and, even also can arrive intraoral each corner and bring into play higher tartar and remove power with more weak sweeping pressure.If it is high-quality green tea part sphering is handled so that be difficult to take place pain when high-quality green tea touches gum, then more preferred.
And then,,, under the situation of the toothbrush that severe periodontosis, gingivitis patients are used, be felt as preferential and be made as below the diameter 0.102mm (4mil), more preferably be made as diameter 0.0508～0.102mm (2～4mil) with in the nominal diameter above-mentioned with excellent contact.On the other hand, under the situation of the toothbrush that slight periodontosis, gingivitis patients are used, be preferably diameter 0.102～0.127mm (scope of 4～5mil).If be made as 0.102～0.127mm (4～5mil) scope, then can obtain massage feeling better, to the good toothbrush of the contiguous sense of gum.Using under the situation with hair thinner than 0.102mm (4mil), though contiguous sense improves, the hair weakened, is weak and use as patients with mild with being preferred as the severe patient.
Usually,, but be not particularly limited based on circle with the shape of cross section of hair.For example, also can use the usefulness hair of triangle, quadrangle, hexagon, petal-shaped iso-cross-section shape, also can be the shape with their combinations in addition.In addition, also can use will be processed into the face shaping of hair integral body in advance wavy, helical form, zigzag etc. with hair, they can also be made up.
So long as the synthetic resin that had used in the past just can use, can use polyamide (for example nylon 6-12, nylon 6-10,12 nylon etc.), polyester (for example PETG, PTT, polybutylene terephthalate (PBT) etc.), polypropylene, synthetic rubber etc. with rough lumber matter.Certainly, also can be the composite filament that their are made up.
In addition, for the raising of the sense that keeps clean, to the bactericidal effect in narrow gap with the hygienic state when preserving, preferably adopt on hair coating or mixed antiseptic antibiotic with mao.As antiseptic can be known antiseptic, has no particular limits.As the example of antiseptic, can enumerate the cationic bactericide etc. of solid solution, money base pottery or the benzyl first and second oxygen amine, benzal hemlock, the chlorhexidine etc. of zinc oxide or zinc oxide and aluminium oxide.
2, plant pore
The size of planting pore obtains higher sweeping efficient and suitable massage feeling in order to reinforce more carefully with the weak property of the hair intensity of pieces, the profiled holes that can make diameter 1.8mm circular port above, the scope of diameter 1.8～2.6mm more preferably or be made of the sectional area of this circular port correspondence.Even the aperture is less, close texturing also can make mao intensity become suitable scope in a way as long as dwindle spacing between the hole, but productivity ratio reduces.Otherwise if the aperture is excessive, then the hair root number of planting with hair becomes many, and it is big that the expansion of pieces becomes, so though be that thin footpath reduces with the entering of hair to close clearance, also can cause the maximization of head width, so the tendency of intraoral operability variation is arranged.Thereby, preferably be made as the scope of above-mentioned aperture correspondence.
In order to carry out close texturing, what fill enough radicals in planting pore is very important with hair.Therefore, preferably will be to planting being made as about 70～95% of pore with the hair filling rate.
The hole shape of planting pore is preferably circle, but also can be polygonal hole or other profiled holes such as square hole.In addition, planting pore also can be single kind, but also can be made of the pore of planting of the different a plurality of kinds of aperture/hole shape.In addition, plant the condition that satisfies above-mentioned hole sectional area at least more than 60% in the pore if be formed on the head all, then also can make up other the cross-sectional area with all size plant pore.
Plant the hole depth (planting the distance of hair side from the head) of pore and plant a mao intensity, so need the degree of depth to a certain degree owing to affecting to the bottom surface of planting pore.Generally, under the more shallow situation of hole depth, pieces is expanded easily, can see that hair erects the tendency of property variation, but plants hair increasing with the hair root number in 1 hole because the aperture is big more, so this tendency manifests more strongly.The expansion of pieces is not only not preferred in appearance, and has high-quality green tea to be difficult to enter into the problem in thinner gap.On the other hand, if make hole depth dark excessively, then the head thickening is more than the degree that needs, intraoral operability variation.
Consider these aspects, present inventors have carried out various experiments, and the result judges, and the ratio that under the situation of circular port, preferably hole depth h is made as 1.7～2.5 times of bore dia d, is about to hole depth h and bore dia d is located in the scope of h/d=1.7～2.5.Under the situation of the hole shape beyond the circle, as bore dia d, as long as adopt the bore dia when being replaced into the identical circular port of sectional area just passable.
The vertical sectional shape of planting pore also can be not have the cylinder hole that changes from the hole upper limb to bottom surface, hole cross sectional shape, but also can adopt with the bottom surface, hole make hemispherical, with the hole shape arbitrarily of bottom side portion chamfering etc.Generally, be preferably the cylindrical bore of bottom surface sections having been implemented the chamfer machining about 0.3mm.
3, plant the arrangement of pore
Plant the hole of pore and arrange except general grid is arranged, can also adopt be staggered or they assembled arrangement etc., arrange in the hole arbitrarily.In order to realize the close texturing of bristle, preferably reduce distance between borehole (the adjacent peritreme of planting pore and the distance between peritreme) as far as possible.Thereby, preferably will the shortest distance between borehole be made as in the scope of 0.1～0.4mm, will plant at least a portion that pore arranges and be made as and be staggered.
It is related significantly with the sweeping efficient of toothbrush and the sensation of brushing teeth to plant gross density.In order to improve sweeping efficient, preferably will plant gross density be made as more than 40%, more preferably 40～55%.Be provided with too muchly if will plant gross density, then reduce to the entering in gap.
In addition, leave distance so long as can guarantee that the MIN width of suitable intensity is just passable between pore and the head outer peripheral edges, can be 0.5～1.5mm, be preferably 0.5～1.0mm planting of most peripheral.
4, bristle
Planting the scope that the 7mm hair intensity of pieces group (bristle) of hair in head is preferably " softness " is 55N/cm
2Below, 30～55N/cm more preferably
2Scope.If the hair strength ratio is a little less than it, then too soft and bring obstacle to cleaning, if it is strong for the hair strength ratio, then the toothbrush of using as periodontosis and gingivitis is really up to the mark, and is not suitable for.
In addition, the staple length (bristle is long) of planting the pieces group behind the hair is preferably the scope of 7.5～13mm, preferably in the less specification of head, make staple length short, in the bigger specification of head, make staple length longer.Head is preferably dimensioned to be about the length x width=15～30mm * 6～12mm of handle long axis direction.
The pruning of planting the bristle behind the hair both can be common straight cuts (truncation is cut), also can make shape arbitrarily such as arch shape, mountain valley shape, concavo-convex stairstepping.If as the arch cutting, disc is made in the upper limb bight of bristle, the contiguous sense of high-quality green tea is improved.In the case, preferably the upper limb bight of bristle is made disc and is cut into arcuation with the scope of 1mmR～10mmR.High-quality green tea is preferably implemented sphering/polishing processing after cutting.
5, toothbrush handles
Material as the hard resin of the matrix part that constitutes toothbrush handles, crooked elastic rate can be for 500～3000MPa, be preferably 1000～2000MPa, be used alone or as a mixture polystyrene resin (PS), acrylic resin (PP), pet resin (PET), acrylonitrile-butadiene-styrene resin (ABS), cellulose propionate resin (CP), many virtueization resins, polycarbonate resin, acrylonitrile-styrene resin (AS) etc., but the aspect from formability, cost etc. is preferably acrylic resin.Under the situation of paying attention to the transparency, see from the aspect of cost and anti-brushing teeth property be preferably U.S. イ-ス ト マ Application corporate system for example as a kind of PCTA resin of mylar etc.
In addition, material as soft resin, can be that hardness (JIS K 6253 hardness tests, experimental condition JIS A) is 5～100, is preferably 20～60 material, can use polyalkenes thermoplastic elastomer (TPE), polystyrene-type thermoplastic elastomers, 1,2 polybutadiene analog thermoplastic elastomer, ethene-vinyl acetate analog thermoplastic elastomer, polyvinyl chloride analog thermoplastic elastomer, natural rubber analog thermoplastic elastomer, fluorine analog thermoplastic elastomer, using trans-polyisoprene analog thermoplastic elastomer etc.
Suitably make alone or in combination by hard resin and soft resin by above-mentioned hard resin for toothbrush handles, but from physical property, price and the mutual intermiscibility that requires as toothbrush material, under the independent situation of hard resin, preferably use acrylic resin, under the situation of combination hard resin and soft resin, preferably use acrylic resin as hard resin, use polyalkenes thermoplastic elastomer (TPE) or polystyrene-type thermoplastic elastomers as soft resin.For example, as the polyalkenes thermoplastic elastomer (TPE), use select respectively EPDM (3 yuan of EVAs of ethylene-propylene-alkadienes) as rubber constituent, select acrylic resin to mix and with part or all crosslinked material that forms as hard component, with their.And then, replace thermoplastic elastomer (TPE), also can use the thermosetting silicones of making by the biliquid hybrid injection.
Structure for the head of planting mao mao's bundle is not particularly limited, but also can be the structure that has made up hard resin and elastomeric multi-ply construction or added linkage at least on a part.The material of elastomeric material and above-mentioned soft resin is same.In addition, also can use at least a portion of head partly to bend or head integral body is bent into various structures such as arc.
6, horizontal line
Under the situation of the toothbrush of horizontal line hair-planted type, as the horizontal line that plants pieces, generally use the horizontal line of the lithographic plate shape of brass or aluminium, but have no particular limits from the aspect of productivity ratio, cost, as long as pieces can be driven into plant in the pore just passable.Material (metal, plastics, natural material etc.), size, shape etc. can at random be selected.
The length of horizontal line also has no particular limits, and can keep pieces reliably and can not make toothbrush head produce the length of breaking or whitening when planting mao but be preferably.Generally can be made as the long axis length longer length of long 0.3～0.5mm also of squeezing into direction than the horizontal line of planting pore.In addition, the squeezing into angle and also can freely select of horizontal line, but for fear of the breaking and whiten of head preferably is made as 5～80 ° angular range, 15～30 ° angular range more preferably with respect to the handle length-wise axis.Squeezing into angle and need not planting in the pore all identically all of horizontal line also can be the different combinations of squeezing into angle.
7, the manufacturing of toothbrush
Use with the spinning of hair as long as and similarly carry out during common toothbrush just passablely, set be rolled into pieces after with nominal diameter extending to.Plant in the horizontal line formula under the situation of hair, with paper etc. this pieces is concentrated, after being cut into sizing (about 25～40mm) again, this cutting part is arranged in the feather planting machine, on one side with withdrawal device grasp set radical with hair, on one side pieces after will grasping squeeze into, plant planting in the pore of toothbrush head with the hair plantation needle doubling with horizontal line.Then, the bristle fore-end is trimmed to shape arbitrarily, high-quality green tea sphering/polishing processing is made the toothbrush of expectation specification with cutting machine.
According to technical scheme 1 described toothbrush, make the cross-sectional area of planting pore be size corresponding to the circular port more than the diameter 1.8mm, making to plant at this synthetic resin of planting in the pore uses the cross-sectional area of hair to be the size corresponding to the circular hair below the diameter 0.127mm (5mil), synthetic resin that will be thinner with Mao Zhimao the planting in the pore of big footpath, good, the toothbrush of contiguous sense so can obtain having higher massage feeling and softness with hair intensity of appropriateness.In addition, thinner become close hair by making with hair, even even can make with more weak sweeping pressure also can arrive intraoral each corner and can bring into play that higher tartar removes that the more weak gum of power also can be massaged with feeling good, also toothbrush preferably of foaming characteristic.And then, be synthetic resin with hair by making bristle, can make stay in grade, can always use with the sensation of cleaning, and the toothbrush that can provide periodontosis and gingivitis to use with the cost near general toothbrush.
According to technical scheme 2 described toothbrushes, make synthetic resin be size corresponding to the following circular hair of diameter 0.102mm (4mil) with the cross-sectional area of hair, making to what plant pore is 70～95% with the hair filling rate, make that to plant gross density be more than 45%, so remove power even also can bring into play higher tartar under the situation of brushing teeth with more weak sweeping pressure (150g is following).Therefore, become the toothbrush that is particularly suitable for severe periodontosis patient or gingivitis patients use.
According to technical scheme 3 and 4 described toothbrushes, making synthetic resin is corresponding to diameter 0.102～0.127mm (size of 4～5mil) circular hair with the cross-sectional area of hair, make that to plant gross density be more than 40%, and plant planting of at least 5% in the pore at all and plant synthetic resin hair in the pore corresponding to the circular hair of diameter 0.127mm (5mil), so even (200～300g) brush teeth with general sweeping pressure, high-quality green tea also can just in time contact on the flank of tooth, can bring into play higher massage feeling and the suitable sweeping power that is used for removing denude.Therefore, become the toothbrush that is particularly suitable for slight periodontosis patient and gingivitis patients use.In addition, because also hairiness intensity, so the bristle durability is also better, even also can not open at once with the sweeping pressure identical high-quality green tea of brushing teeth with healthy person.
According to technical scheme 5 described toothbrushes, because making the ratio h/d of the bore dia d that plants pore and hole depth h is 1.7～2.5 scope, so can use thin footpath with hair and big footpath plant pore in realize the higher mao intensity of planting, can eliminate that hair comes off etc. and the life-span of prolongation toothbrush.
According to technical scheme 6 described toothbrushes, be 0.1～0.4mm owing to make the adjacent the shortest distance between borehole of planting between the pore, so can realize further close texturing, can realize each above-mentioned effect more reliably.
