The specific embodiment
Below, with reference to the interdental brush of description of drawings example of the present invention.
As shown in Figure 1, the interdental brush of this embodiment 1 is constituted with the handle portion 6 that is connected with brush portion 4 through neck 5 by the neck 5 at the base end part 2a that turns round brush portion 4 that clamping between the stubborn silk thread 2 has filament 3 to form, strut wires 2 substantially.
Shown in Fig. 3 C, the structure of brush portion 4 is, in 2 bursts of each gaps 7 of turning round stubborn silk thread 2, from front end 2b side continuously or at certain intervals intermittently clamping the bundle of many filaments 3 is arranged.
Again, like Fig. 1, shown in Figure 2, filament 3 is configured to tilt to the angle [alpha] of the base end part 2a of silk thread 2 side with defined with respect to the axis of silk thread 2.
Especially, with respect to the axis of silk thread 2, above, the scope below 60 degree of preferred 20 degree of the angle [alpha] that filament 3 forms.
The brush portion 4 that constitutes like this shown in Fig. 3 A～Fig. 3 C, twists into 2 strands with silk thread 2, and clamping forms the roughly filament 3 of V-shape between 2 strands the silk thread 2 twisting into, and twists silk thread 2 and forms through turning round.
Again, as other method, at first; The filament 3 of linearity is clamped in the silk thread 2 that twists into 2 strands; Make brush portion 4 through turning round stubborn silk thread 2, afterwards, will omit illustrated tube coniform or cylindraceous and cover brush portion 4; Make filament 3 that angle arranged, form through implementing the thermal finalization solid shape.Under such situation, give operating in of angle to filament 3 and carry out all can before or after brush portion 4 is embedded in handle portion 6.
Also can in the scope of the characteristic of not damaging filament 3, carry out modification again.For example; Can in resin, suitably mix modifier, other hard resins or the elastomer etc. of stabilization agent more than a kind or 2 kinds, fire retardant, filler, surface lubricant, antistatic additive, sterilization raw material (antibiotic raw material) etc., or also can be coated on the individual filament heat or light.
(in 1.2～5mil) the scope, more preferably 0.05～0.09mm is (in 2～3.5mil) the scope for the preferred 0.03～0.13mm of the rugosity of filament 3.
Moreover; The size of interdental brush 1 is limited the size of interdental space; Usually distinguish according to its size and use filament 3, consider usability, sweeping property, cleaning effect, durability etc., also can on 1 interdental brush 1, make up the different a plurality of filaments 3 of rugosity.
Except rugosity, also can change material, length, color, cross sectional shape again.
The cross sectional shape of filament 3 also can be between the clover shape isoline of the polygon of elliptical shape or triangle, quadrangle etc., star-like, three leaves or four leaves, between the curve and made up the irregularly shaped of straight line and curve except that circular (round).
The cross section of the hair of interdental brush 1 (hair is cut り) (perhaps profile) shape can be set at arbitrary shape.For example, as shown in Figure 2, the length of filament 3 constitutes with identical length respectively, and silk thread 3 is configured to: in each silk thread base end part 2a side, tilt with identical angle [alpha] with respect to the axis of silk thread 2.
Material as neck 5 and handle portion 6; Can be separately or mix use polystyrene resin (PS), acrylic resin (PP), polyethylene terephthalate resin (PET), acrylonitrile butadiene polystyrene resin (ABS), cellulose propionate resin (CP), polyene propyl ester resin, saturated polyester resin (PCTA, PCTG), polycarbonate resin (PC), AS resin acrylonitrile styrene resin (AS), gather the raw material of acetal resin (POM), polybutylene terephthalate (PBT) (PBT), Biodegradable resin etc.Again, also can be between these resins or with the multicolour forming handle of combination such as thermoplastic elastomer (TPE), silicones.Just, need not to be defined in these materials, so long as can use as neck 5 and handle portion 6, then can be any material.
Have in the interdental brush 1 of above such structure, filament 3 is configured to: with respect to the axis of silk thread 2, tilt to the angle [alpha] of the base end part 2a of silk thread 2 side with regulation.As a result, obtain the effect that between cog property inserted and between cog cleaning power increase.
Therefore that is, among the present invention, because filament 3 is configured to insert with acute angle with respect to direction of insertion to the base end part 2a of silk thread 2 side with the angle of regulation at a slant.As a result, the resistance in the time of can reducing to insert.Again, when pulling out interdental brush 1, filament 3 can tail off in the situation that the rightabout of pull-out direction falls down, and can between tooth, stumble through the front end that makes filament 3, scrapes dirt thus effectively.
Again, need not be soft material with the material altering of filament 3, can use material in the past, so between cog cleaning power can not reduce.
In addition, among the present invention, in the base end part 2a of silk thread side, with respect to the axis of silk thread 2, the angle [alpha] that filament 3 forms is preferably in the scope more than 20 degree, below 60 degree.
Thus, the between cog of interdental brush 1 property inserted and between cog cleaning power improve more.Therefore that is, because angle [alpha] is more than 20 degree, when pulling out interdental brush 1, filament 3 can be stumbled between cog, can more effectively remove dirt.Again, because angle [alpha] is that the resistance when therefore inserting is littler below 60 degree, filament 3 can become still less to the situation that the opposition side of pull-out direction falls down when pulling out, and between cog cleaning power improves more.
More than, according to embodiment the present invention has been described, but the present invention is not limited to above-mentioned embodiment, can carry out various changes in the scope that does not break away from its main points.
For example; In this embodiment; Be illustrated with regard to the I font interdental brush of neck 5, but also can be the L font interdental brush that neck roughly becomes the length direction of L font, brush portion and handle portion to be formed generally perpendicularly for the length direction almost parallel ground formation of linearity, brush portion and handle portion 6.
Again, as shown in Figure 4, the cross sectional shape of the hair of interdental brush 1 also can be configured to: the filament 3 in each gap that is clamped in silk thread 2 is from the front end 2b side direction base end part 2a side of silk thread 2, and staple length is elongated gradually.Again, filament 3 also can be configured to: in the middle of the front end 2b side and base end part 2a side direction of silk thread 2, staple length is elongated gradually or shorten.
