The specific embodiment

Below, to having used toothbrush of the present invention and manufacturing approach thereof, specify with reference to accompanying drawing.

In addition, the following accompanying drawing of explanation, in order to understand characteristic easily, the part of representation feature for simplicity and schematically sometimes, the dimension scales of each structural element etc. are not necessarily identical with reality.In addition, according to occasion, omit the diagram of pieces.

As example of the present invention, the toothbrush 1 shown in Figure 1A and Figure 1B has the whole brush holder 1A that constitutes strip, and this brush holder 1A comprises: shank 2; Be located at the brushhead 3 of these shank 2 tip side; And be located at the neck 4 between shank 2 and the brushhead 3.

Brush holder 1A, its shank 2, the neck 4 that links to each other with this shank 2 are for example integrally formed by the hard resin material with the brushhead 3 that links to each other with this neck 4.As the employed hard resin material of brush holder 1A; Can enumerate polypropylene, polyethylene, PETG, gather the cyclohexene dimethylene terephthalate, the thermoplastic resin material of saturated polyester resin, polymethyl methacrylate, cellulose propionate, polyurethane, polyamide, ABS (acrylonitrile-butadiene-styrene (ABS)) etc., but be not limited to these materials.

The part that shank 2 persons of being to use are controlled, but on this shank 2 also a part or whole part cover the for example soft resin of elastomer etc., with controlling property of raising.Neck 4 is with portions joined between shank 2 and the brushhead 3, owing to be not certain clear and definite and shank 2 and brushhead 3 distinguishing parts, therefore, sometimes also can be as broad as long according to occasion with shank 2 and neck 4.Therefore, brush holder 1A also directly is provided with the shape of brushhead 3 on the top of shank 2, and its shape, size, outward appearance etc. can be done to change arbitrarily to implement.

Brushhead 3 so long as clean easily intraoral shape with the size get final product, be not particularly limited for its shape, but generally constitute roughly cuboid.And, last, as shown in Figure 2 at one side (be called and the plant hair side) 3a of this brushhead 3, be provided with the pieces 6A that is used to implant bristle 5, a plurality of pores 7 of planting of 6B at the length direction and the width structure arow of said brushhead 3.

For improving high-quality green tea entering between cog portion and tooth stem etc.; For

pieces

6A, 6B; The bristle that has used the high-quality green tea shape of each bristle 5 that will constitute this

pieces

6A, 6B to give sharpening; Promptly shown in Fig. 3 A and Fig. 3 B, used diameter from the tapered bristle of high-quality green tea 5a at its central side direction two ends (below be called the taper bristle) 5.

Material for taper bristle 5; Polypropylene), the synthetic resin material of elastomer (example: propylene system, polystyrene) etc. be not particularly limited, can use polyamide (example: 6-12 nylon, 6-10 nylon) for example, polyester (example: PETG, polybutene terephthalate, PTT), polyolefin (example:.In addition, can be a plurality of combinations use these resin materials, for example can be like core sheath structure etc. suchly at sheath portion and the different resin material of core use.Wherein, for taper hair 5, preferably use through bristle (filament) being immersed in the basic hydrolysis inorganic agent and dissolving and high-quality green tea is made the goods of taper, this bristle is made up of the polybutene terephthalate that is cut into specific length.

The staple length of taper bristle 5, that leaves brushhead 3 plants hair side 3 preferably, big human be 8～13mm, child uses is 6mm～9mm.The thickness of taper bristle 5 (maximum gauge) sees from the viewpoint of intraoral usability and usability, preferably 0.12～0.26mm.

Pieces

6A, 6B are as shown in Figure 2, and it is two that above-mentioned many bristles 5 are bundled into the Shu Bingyi folding, sandwich the anti-avulsion part that is called lenticular wire 8 betwixt and squeeze into and plant in the pore 7, are implanted in respectively planting in the pore 7 of brushhead 3 thus.

Central part and the leap of lenticular wire 8 through planting pore 7 planted pore 7 ground and is driven in planting pore 7.As the material of lenticular wire 8, for example can enumerate metals such as brass and stainless steel, other also can enumerate rigid plastics or Biodegradable plastics etc.Lenticular wire 8 its length are greater than the diameter of planting pore 7, and its width is less than the degree of depth of planting pore 7.In addition, for the length of lenticular wire 8 and width, thickness, also can combine

pieces

6A, 6B and plant pore 7 and adjustment arbitrarily.Especially, through the thickness of adjustment lenticular wire 8, can

pieces

6A, 6B be fixed on to plant in the pore 7 reliably and also can reduce the space.In addition, lenticular wire 8, its length from the both sides exposed portions serve of planting pore 7 adds up to preferably 0.3～0.6mm, in case anti-avulsion goes out to plant pore 7.

Yet; In having used toothbrush 1 of the present invention; Like Figure 1A～shown in Figure 2, what pieces 6A, the 6B through the taper bristle 5 that top end diameter is different implanted brushhead 3 plants hair side 3a, makes and is implanted in the pieces 6A that plants hair side 3a of brushhead 3, the top end diameter of 6B has difference.

Specifically, when making this toothbrush 1, at first shown in Fig. 3 B, with clipping lenticular wire 8 and by a folding be two taper bristle 5 at one end and be provided with difference of height t ground between the other end and turn back.And; Shown in Fig. 4 A and Fig. 4 B; Plant in the pore 7 what planting of brushhead 3 was provided with on the hair side 3a, implant lenticular wire 8 is clipped and is pieces 6A, the 6B of two taper bristle 5 by a folding and between an end (side becomes mildewed) 6a, 6c and the other end (undercoat side) 6b, the 6d difference of height is being set separately.In addition, these implantation plant each pieces 6A in the

pore

7,6B lenticular wire 8 towards the direction of setting regulation for.

Thus, brushhead 3 plant hair side 3a, each

pieces

6A, 6B top integral body just have the undulations 9 of solid such shown in Fig. 4 A and Fig. 4 B.That is, this undulations 9 has two top 9a that arrange along the length direction of brushhead 3 at the middle body of planting hair side 3a, and staple length is from the bottom 9b continuous step-down of these two top 9a around it.

Said undulations 9 is as shown in Figure 5; Between top 9a and bottom 9b; Be provided with among the

pieces

6A, 6B of difference of height; Make an adjacent side's undercoat side 6b and the opposing party's the side 6c that becomes mildewed of pieces 6B of pieces 6A relative, and the staple length of the side 6c that becomes mildewed of said the opposing party's pieces 6B is made identical or shorter than it with the staple length of the undercoat side 6b of a said side's pieces 6A.That is, be made as t when staple length with become mildewed side 6a and the undercoat side 6b of a side pieces 6A _a, t _b, the staple length of become mildewed side 6c and the undercoat side 6d of the opposing party's pieces 6B is made as t _c, t _dThe time, satisfy t _a＞t _b>=t _c＞t _dRelation.

In addition; In this example; Pieces 6A for a side; Use the taper bristle of staple length, use the taper bristle of staple length, and respectively plant in the pore 7 the 1mm difference of height is set being implanted between an end (side becomes mildewed) 6a, 6c and the other end (undercoat side) 6b, the 6d separately as 29mm for the opposing party's pieces 6B as 31mm.

Thus, between the top of undulations 9 9a and bottom 9b, can make the staple length of

pieces

6A, 6B different continuously, brushhead 3 plant that hair side 3a goes up each the pieces 6A that is provided with, the top integral body of 6B just has level and smooth undulations 9.

In addition; As shown in Figure 2, the second pieces crowd 10B that the first pieces crowd 10A that said undulations 9 is made up of a plurality of (four) the pieces 6A around the center S that surrounds two top 9a and a plurality of (11) the pieces 6B that surrounds the first pieces crowd 10A are again constituted forms.In addition, among Fig. 2, plant a plurality of of hair side 3a and plant in the pore 7 being located at, utilize color that side's side (side becomes mildewed) 6a that clips

lenticular wire

8,6c and the opposing party's side (undercoat side) 6b, the 6d of each

pieces

6A, 6B distinguished expression.

And; Constitute these first and second pieces crowd 10A, 10B each

pieces

6A, 6B lenticular wire 8 towards setting the direction of dividing an enclosing region by the extended line of separately lenticular wire 8 for, and only the side 6a that becomes mildewed, the inboard that 6c is positioned at enclosing region of each pieces 6.In addition, the lenticular wire 8 of each

pieces

6A, 6B sets for and the straight line that center S and said pieces 6A, the 6B of top 9a the coupled together direction of quadrature (90 °) roughly towards (squeezing into angle).

Thus, the hair side 3a that plants of brushhead 3 goes up each the pieces 6A that is provided with, the top of 6B, just has the undulations 9 of staple length from the bottom 9b continuous step-down of above-mentioned two top 9a around it.

Then, prune on each pieces 6A that plants the last setting of hair side 3a of brushhead 3, the top of 6B.Specifically, along the line of cut C shown in Fig. 4 A～Fig. 5, the top through so-called truncation with each

pieces

6A, 6B trims into the plane.Thus; The hair side 3a that plants of brushhead 3 goes up each the pieces 6A that is provided with, top that kind shown in Figure 1B amplification of 6B; Show the distribution that its top end diameter attenuates by the order of the end 6c of the end 6a of a side pieces 6A and other end 6b, the opposing party's pieces 6B and other end 6d successively, and show the distribution that the top end diameter of

pieces

6A, 6B attenuates from above-mentioned S concentric circles ground, two centers shown in Figure 2 continuously.

Promptly; The hair side 3a that plants of brushhead 3 goes up each pieces 6A, the 6B that is provided with, and trims into the plane through the top that it is had above-mentioned undulations 9, thus; The staple length of taper bristle 5 that constitutes each

pieces

6A, 6B is high more, and the top end diameter of the high-quality green tea 5a after the pruning is just thick more.Therefore, corresponding with staple length in this toothbrush 1 from two top 9a 9b continuous step-down in bottom around it of above-mentioned undulations 9, prune the distribution that the back shows that the top end diameter of each

pieces

6A, 6B attenuates continuously.

In the toothbrush with above-mentioned the sort of structure 1, the hair side 3a that plants of brushhead 3 goes up each pieces 6A, the 6B that is provided with, because its top end diameter to above-mentioned two center S chaps shown in Figure 2, therefore, has been strengthened the hair rigidity at these two cores.On the other hand, in this toothbrush 1,, therefore, can make a mao rigidity softness at these peripheral parts because top end diameter attenuates to concentric circles from two cores laterally.

Therefore, in this toothbrush 1, when the even surface of tooth face etc. was scrubbed, two strong cores of hair rigidity contacts with the tooth face, obtain the high true feeling of scrubbing thus, and the while can be improved the dirty removal power of tooth.On the other hand, in this toothbrush 1,, therefore, the tooth stem can be do not damaged, the tooth neck can be scrubbed because the soft peripheral part of hair rigidity mainly contacts with the tooth neck.In addition, because the high-quality green tea of peripheral part is thin, therefore, can improve the high-quality green tea entering that high-quality green tea gets into narrow and small positions such as tooth rim slit.Therefore, in this toothbrush 1, high cleaning true feeling can be obtained, cleaning property can be fully guaranteed simultaneously for the position of high-quality green tea entering variation such as between cog portion and tooth stem.

As stated; In having used toothbrush 1 of the present invention; Top end diameter through making the pieces of planting hair side that is implanted in brushhead has difference; Do not rely on special cutting mao shape and do not need complicated pieces to arrange and a plurality of bristle types, just can easily obtain the differential of functional and usability aspect.

That is, in toothbrush in the past, in order to obtain above-mentioned functional and usability, must plant pore to each and implant the different taper bristle of top end diameter, therefore, it is clear and definite that the border of each pieces becomes easily.On the contrary, in having used toothbrush 1 of the present invention, because can be with clipping lenticular wire 8 and be that two

pieces

6A, 6B make the different style of top end diameter with half pieces unit by a folding, therefore, compare the top end diameter that in the past can make

pieces

6A, 6B and gently change continuously.For example, in this example, from two kinds of different successively pieces 6A of the staple length that makes above-mentioned taper bristle 5,6B, obtain having pieces 6A, the 6B of four kinds of top end diameter, therefore, can obtain unexistent in the past very thin and first-class tactility with half pieces unit.

In addition; In the present invention, needn't plant pore to each and implant the different taper bristle of top end diameter or adopt the complicated mao shape of cutting, in addition; Can more merely arrange and plant pore; Therefore keeping under the state of simple outward appearance, the differential of function can be obtained, the high toothbrush of the sort of design freedom 1 can be made inexpensively.

In addition, the present invention not necessarily is limited to the structure of above-mentioned toothbrush 1, in the scope that does not break away from aim of the present invention, can do various changes.In addition, in following explanation, for the equal position of above-mentioned toothbrush 1, omit explanation, put on same-sign for simplicity.

In above-mentioned toothbrush 1; When the top end diameter of planting pieces 6a that hair side 3a go up to implant, 6b that makes brushhead 3 not simultaneously; Not the structure that is defined in the undulations 9 shown in above-mentioned Fig. 4 A and Fig. 4 B, can do any change for the configuration of its top 9a and bottom 9b and quantity etc.In addition, the undulations (profile) between top 9a and the bottom 9b also can freely be set, and for example, can under the state of keeping taper bristle 5 high-quality green tea shapes, freely design mountain shape, dome-shaped, dome shape equal ripple shape.

Promptly; In the present invention; When with the pieces 6A of taper bristle 5,6B one folding being two, and will sandwiching therebetween lenticular wire 8 and squeeze into when planting in the pore 7; Can freely set the difference of height of the side 6a that becomes mildewed, 6c and undercoat side 6b among each pieces 6A, the 6B, 6d, the pieces 6A that constitutes pieces crowd 10A, 10B, 6B configuration and quantity and

pieces

6A, 6B lenticular wire 8 towards (squeezing into angle) etc., through making up these, do not adopt such in the past cutting a mao shape, this method of difference of height being set of forming of pruning with pieces unit; Just can give design freedom high undulations, and make easily the top of

pieces

6A, 6B.

For example, in above-mentioned toothbrush 1, also can give the undulations 9A of solid such shown in Fig. 6 A and Fig. 6 B to the top of planting the last pieces 6A that implants of

hair side

3a, 6B of brushhead 3.Specifically, in this undulations 9, have length direction two the bottom 9b side by side along brushhead 3 at the middle body of planting hair side 3a, staple length uprises from these two bottom 9b top 9a around it continuously.

In this occasion; Through along the line of cut C shown in Fig. 6 A and Fig. 6 B; Utilize truncation that the top of each

pieces

6A, 6B is trimmed into the plane; Thus, the top of planting each pieces 6A that hair side 3a go up to be provided with, 6B of brushhead 3 and staple length uprise corresponding continuously from two bottom 9b top 9a around it of above-mentioned undulations 9A, prune the distribution of the continuous chap of top end diameter of each pieces 6A of back demonstration, 6B.

Therefore, in this occasion, at two cores, pieces 6A, the easy deflection of 6B can be in their peripheral part raising pieces 6A, the hair rigidity of 6B.Thus, when for example the big protuberance of the inside tooth tooth cheek sidepiece being scrubbed, at above-mentioned two cores,

pieces

6A, 6B just suitably sink to, and can improve anastomose property and cleaning property to tooth.

In addition, in the present invention,, be not limited to dispose the structure of become mildewed side 6a, the 6c of each

pieces

6A, 6B, also can make the structure of

configuration undercoat side

6b, 6d in the inboard of the enclosing region of dividing by the pieces 6A of above-mentioned pieces crowd 10A, 10B, 6B.In this occasion, trim into the plane through top with

pieces

6A, 6B, thus, have the distribution that the top end diameter of

pieces

6A, 6B diminishes towards the inboard of enclosing region successively.

In addition; In the present invention; Be not limited to that all are planted pore 7 and are implanted into the pieces 6A that is provided with above-mentioned difference of height, the situation of 6B in that planting of above-mentioned brushhead 3 is provided with on the hair side 3a, also can make and the pieces 6A, the 6B that are provided with difference of height are implanted in a part plant the structure in the pore 7.That is, in the present invention,, can use with the pieces 6A that is provided with above-mentioned difference of height, 6B combination in any sandwiching side's side behind the lenticular wire 8 pieces identical etc. with the staple length of the opposing party's side according to the design of above-mentioned undulations 9.

In addition,, also can change the length of above-mentioned taper bristle 5, or change and to clip lenticular wire 8 and be the position of turning back of two taper bristle 5 by a folding in the staple length occasion inequality that makes the side 6a that becomes mildewed of each

pieces

6A, 6B, 6c and undercoat side 6b, 6d.In addition, in the present invention, consider usability, scrub sense, clean effect and durability etc., taper bristle 5 that also can rugosity is different with the taper angle carries out combination in any to be used.

In addition; Implantation has in each the pieces 6A that constitutes above-mentioned pieces crowd 10A, 10B, 6B, adjacent pieces 6A, the interval of planting pore 7 (planting the beeline between pore) of 6B; Be preferably in and do for a short time in the scope that to guarantee brushhead 3 intensity, specifically, be preferably made the scope of 0.6～1.0mm.If this less than 0.6mm, then is difficult to guarantee the intensity of brushhead 3 at interval, and on the other hand, if surpass 1.0mm, each the pieces 6A, the interval between 6B that then constitute pieces crowd 10A, 10B are too open, are difficult to form smoothly above-mentioned undulations 9 at interval for this.

The diameter of in addition, planting pore 7 is preferably more than the 1.0mm.If the diameter of planting pore 7 is less than 1.0mm, and the pieces 6A, the side 6a that becomes mildewed of 6B, the 6c hair rigidity that then are provided with difference of height die down, and cleaning true feeling descends.On the other hand, for the upper limit of planting pore 7 diameters,, be not particularly limited as long as can guarantee the quality such as intensity of usability, brushhead 3 and can form required undulations 9.The degree of depth of in addition, planting pore 7 is 2.7～4.3mm preferably.If the degree of depth of planting pore 7 is less than 2.7mm, and then lenticular wire 8 comes off with

pieces

6A, 6B easily.On the other hand, plant the degree of depth of pore 7 if surpass 4.3mm, brushhead 3 undue thickenings then, the operability of toothbrush 1 is decline just.

The top end diameter of taper bristle 5 after pruning that constitutes each

pieces

6A, 6B is preferably in the scope of 10～220 μ m inequality.If top end diameter is less than 10 μ m, and then the rigidity of high-quality green tea too dies down, and wiper power just descends.On the other hand, top end diameter is if surpass 220 μ m, the undue grow of hair rigidity of high-quality green tea then, tactility variation.

In addition; The shape of cross section of taper bristle 5 is preferably circular; But be not defined as this shape; For example also can do ovalisation, polygon (for example triangle, quadrangle, pentagon and hexagon etc.) and abnormity (for example clover shape of the clover shape of star, three leaves, four leaves etc.), can make arbitrary shape according to the purpose purposes of toothbrush 1.In addition, this taper bristle 5 also can be done spirality, or is provided with embossing etc.

In addition; Each

pieces

6A, 6B use usually many taper bristles 5 bundle are bundled into the pieces behind the circular shape; But be not limited to this circular shape of Shu Zhacheng; But also Shu Zhacheng general triangular or roughly quadrangle etc. is roughly polygon-shaped in addition, also can be used Shu Zhacheng substantially elliptical, roughly Long Circle, roughly rectangle, the pieces of major diameter such as polygon and minor axis shape inequality roughly.

In addition; Planting on the hair side 3a of brushhead 3; Common length direction, width in brushhead 3; With predetermined distance clathrate or zigzag ground alignment arrangements the circular pore 7 of planting is arranged, but for the configuration of planting pore 7, at interval, their combination etc. do not limit, can change arbitrarily according to the purpose purposes of toothbrush 1.

In addition; Plant the shape of cross section of pore 7, according to the pieces 6A after above-mentioned taper bristle 5 bundles are pricked, the shape of 6B, normally circular; But be not limited to this shape, can make arbitrary shape according to the pieces 6A after above-mentioned taper bristle 5 bundles are pricked, the shape of 6B.
