The specific embodiment
Below, to having used toothbrush of the present invention, be described in detail with reference to accompanying drawing.
In addition, understand easily in order to make feature, in the employed in the following description drawing, have the situation that will schematically show as the part of feature from convenient the consideration, the size of each inscape is not limited to actual identical than waiting.In addition, according to circumstances omit the diagram of pieces.
As example of the present invention, toothbrush 1 shown in Figure 1 have whole be the brush holder 1A of long chi shape, this brush holder 1A have handle portion 2, be arranged on the head 3 of these handle portion 2 tip side and be arranged on handle portion 2 and head 3 between neck 4.
Brush holder 1A by handle portion 2, therewith the neck 4 that links to each other of handle portion and therewith the head 3 that links to each other of neck constitute by for example the hard resin material is one-body molded.As the hard resin material that on brush holder 1A, uses, can enumerate for example polypropylene, polyethylene, PETG, poly-cyclohexene dimethylene terephthalate (Port リ シ Network ロ ヘ キ シ レ Application ヅ メ チ レ Application テ レ Off タ レ one ト), saturated polyester resin, polymethyl methacrylate, cellulose propionate, polyurethane, polyamide or ABS thermoplastic resin materials such as (acrylonitrile-butadiene-styrene (ABS)s), but be not limited in these materials.
The part that handle portion 2 persons of being to use control in order to improve controlling property, also can cover soft resins such as being formed with elastomer for example on a part or whole part of this handle portion 2.Though neck 4 is for connecting the part between handle portion 2 and the head 3, handle portion 2 and head 3 are not the part that must clearly distinguish, therefore, according to circumstances have as broad as long structure between handle portion 2 and the neck 4 yet.Therefore, brush holder 1A also can be the shape that directly is provided with head 3 on the top of handle portion 2, can at random implement change to its shape, size, design etc.
As shown in Figures 2 and 3, head 3 is so long as easy shape and big or small getting final product to cleaning in the oral cavity to the not special qualification of its shape, but are generally made roughly rectangular-shaped.And, as shown in Figure 3 and Figure 4, on a face (be called and the plant hair side) 3a of this head 3, be provided with a plurality of pores 7 of planting of the pieces 6A, the 6B that are used to implant bristle 5 along arow on the length direction of this head 3 and the width.
In order to improve the high-quality green tea entering between cog portion and tooth stem etc., pieces 6A, 6B use the bristle of the high-quality green tea shape sharpening of each bristle 5 that will constitute this pieces 6A, 6B, that is, and as shown in Figure 5, use is from the high-quality green tea 5 at its mediad two ends
The bristle that a diameter attenuates gradually (being called the taper hair) 5.
Material for bristle 5, polypropylene), the synthetic resin material of elastomer (example: propylene system, polystyrene) etc. do not limit especially, can use polyamide (example: 6-12 nylon, 6-10 nylon) for example, polyester (example: PETG, polybutene terephthalate, PTT), polyolefin (example:.In addition, these resin materials can be a plurality ofly be used in combination, for example the sheath portion resin material different can be as core sheath structure etc., used with core.Wherein, for the taper hair, preferably use by 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 of the polybutene terephthalate that is cut into specific length.
The staple length of bristle 5, from the head 3 plant words 8mm～13mm the best that hair side 3a begins to calculate, the adult uses, words 6mm～9mm the best that children use.Consider that from intraoral usability and usability aspect the thickness of bristle 5 (maximum gauge) is 0.12mm～0.26mm the best.In addition, from considerations such as usability, sweeping sense, cleaning effect, durability, many bristles 5 that also can thickness is different suitably make up and use.
As shown in Figure 3 and Figure 4, pieces 6A, 6B by with many, be preferably above-mentioned bristle 5 about 10～50 and be bundled into bundle and be converted into two parts, between it, sandwich the anti-avulsion part that is called flat wire 8 and it squeezed into and plant in the pore 7, thus it is implanted head 3 each plant in the pore 7.
As Fig. 2, Fig. 3 and shown in Figure 4, in having used toothbrush 1 of the present invention, head 3 plant on the hair side 3a set plant to implant in the pore 7 pieces 6A is arranged, 6B, this pieces 6A, (6B becomes mildewed side owing to a side of seizing flat wire 8 on both sides by the arms, broad wool portion) 6a, 6c and opposite side (undercoat side, undercoat portion) 6b, 6d and have difference of height, by suitably setting this pieces 6A, the direction of the flat wire 8 of 6B, and make each pieces 6A, the top of 6B (aggregate) as a whole becomes three-dimensional undulations 9 (undulations portion) (the planar portion that is made of the aggregate on the top of pieces 6A and 6B is three-dimensional undulations).In addition, in Fig. 3, set a plurality of planting in the pore 7 on planting hair side 3a, with a side of seizing flat wire 8 on both sides by the arms (side that becomes mildewed, broad wool portion) 6a, 6c and opposite side (undercoat side, the undercoat portion) 6b of each pieces 6A, 6B, 6d distinguishes expression by color classification.
Specifically, this undulations 9 at two tops (mountain portion) 9a that has on the middle body of planting hair side 3a on the length direction of head 3 side by side, makes staple length from these two top 9a bottom 9b (paddy portion) around it step-down continuously.
In having used toothbrush 1 of the present invention, in order to form above-mentioned undulations 9, as shown in Figure 4, between top 9a and bottom 9b, in having pieces 6A, the 6B of difference of height, make an adjacent side's the undercoat side 6b of pieces 6A and the opposing party's the side 6c that becomes mildewed of pieces 6B relative, and make the opposing party's the staple length of staple length and the undercoat side 6b of a side pieces 6A of the side 6c that becomes mildewed of pieces 6B identical or than shorter for best.That is, represent with ta, tb that when the staple length of become mildewed side 6a and the undercoat side 6b of a side pieces 6A the staple length of become mildewed side 6c and the undercoat side 6d of the opposing party's pieces 6B is with tc, when td represents, the pass of satisfying ta＞tb 〉=tc＞td is best.Thus, the staple length that can make pieces 6A, 6B is different continuously between the top of undulations 9 9a and bottom 9b, the top of planting each pieces 6A, 6B on the hair side 3a that is arranged on head 3 can be made as a whole along sliding concaveconvex shape (aggregate of the top ends by being arranged on the whole pieces 6A that plants on the hair side 3a and 6B presents along sliding undulations).
In addition, the difference of height of become mildewed side 6a, 6c and undercoat side 6b, the 6d of each pieces 6A, 6B is scope the best of 0.3～1.0mm.When the not enough 0.3mm of this difference of height, because of having not enough tendency with visual effect on the different functions that cause of staple length.On the other hand, when this difference of height surpasses 1.0mm, have the top that makes pieces and contact the tendency that integral body becomes difficult in the oral cavity effectively, in addition, only have the tendency that the top of pieces 6A, the 6B of a part enters privileged sites such as between cog portion and tooth neck, therefore have the tendency that the sense of touch of high-quality green tea degenerates.
In addition, in having used toothbrush 1 of the present invention,, as shown in Figure 3, preferably have: the 1st pieces group 10A that constitutes by multi beam (4 bundle) the pieces 6A that surrounds around the S of center with respect to the center S of two top 9a in order to form above-mentioned undulations 9; The 2nd pieces group 10B by the multi beam around further encirclement the 1st pieces group 10A (11 bundle) pieces 6B formation.
The 1st pieces group 10A and the 2nd pieces group 10B constitute by pieces 6A, the 6B with above-mentioned difference of height.The 1st pieces group 10A preferably constitutes by the pieces 6A of 3 bundles, better 4～6 bundles at least.In addition, the 2nd pieces group 10B is by the pieces 6B formation of at least 3 bundles, better 6～15 bundles.
The direction of the flat wire 8 of each pieces 6A, the 6B of these formation pieces group 10A, 10B, be set at by the extended line of flat wire 8 separately an enclosing region is carried out the direction of zoning, and only make become mildewed side 6a or the 6c of each pieces 6 be positioned at the inboard best of each enclosing region.In addition, in the inboard of above-mentioned enclosing region, have top 9a the best of undulations 9.And more preferably,, set roughly orthogonal direction (90 °) for the direction (squeezing into angle) of the flat wire 8 of each pieces 6A, 6B straight line with respect to the center (center of the length direction of flat wire 8) of the center S that connects top 9a and this pieces 6A or 6B.Here, the center of the center S of top 9a and pieces 6A or 6B is present on the same plane and (plants on the hair side 3a).
Thus, in having used toothbrush 1 of the present invention, can make be arranged on head 3 plant each pieces 6A on the hair side 3a, the top of 6B becomes undulations 9, this undulations makes staple length from the bottom 9b step-down of above-mentioned two top 9a around it continuously.
In addition, in each pieces 6A, 6B of constituting above-mentioned pieces group 10A, 10B, implantation has the interval of planting pore 7 (planting the minimum distance between the pore) of adjacent pieces 6A, 6B, is preferably in the strength range that can guarantee head 3 to diminish, specifically, best in the scope of 0.6～1.0mm.When the not enough 0.6mm in this interval, has the tendency of the intensity difficulty of guaranteeing head 3.On the other hand, when this surpasses 1.0mm at interval, constitute pieces group 10A, the interval between each pieces 6A, the 6B of 10B becomes excessive, has the tendency that above-mentioned undulations 9 is formed smoothly the difficulty that becomes.In addition, about usability, have following tendency: the mutual support of adjacent pieces 6A, 6B dies down, and the movable area of become mildewed side 6a, 6c with pieces 6A, 6B of difference of height becomes big, and therefore, a hair pars intermedia dies down, cleaning true feeling step-down.
In addition, plant diameter the best more than 1.0mm of pore 7.When the not enough 1.0mm of the diameter of planting pore 7, the hair pars intermedia of become mildewed side 6a, 6c with pieces 6A, 6B of difference of height dies down, and has the tendency of cleaning true feeling step-down.On the other hand, for the diameter upper limit of planting pore 7, if can guarantee the product Quality such as intensity of usability and head 3 and can form desirable undulations 9, then not especially necessity limit, but best below 3m m.In addition, the degree of depth of planting pore 7 is 2.7～4.3mm the best.When planting the degree of depth deficiency 2.7mm of pore 7, has the tendency that flat wire 8 and pieces 6A, 6B come off easily.On the other hand, when the degree of depth of planting pore 7 surpassed 4.3mm, head 3 became blocked up, has the tendency of the operability step-down of toothbrush 1.
In toothbrush 1 with above this spline structure, can will not give to the pieces 6A that is provided with on the hair side 3a planting of head 3, the top of 6B by the undulations 9 of cutting the solid that mao shape forms, by giving the aggregate that constitutes to the top by pieces 6A, 6B with such undulations 9, privileged sites such as whole or between cog portion and tooth neck contact effectively in the top that can make pieces 6A, 6B and the oral cavity.In addition, in this toothbrush 1, constitute each pieces 6A, 6B, therefore, can improve pieces 6A, 6B high-quality green tea entering between cog portion and tooth stem etc. by bristle (taper hair) 5 with the sharpening of high-quality green tea shape.Therefore, in this toothbrush 1, high cleaning true feeling and operability can be obtained, and, spatter property can be fully guaranteed for the place of high-quality green tea entering variation such as between cog portion and tooth stem.
