Each group forms tooth contact-making surface 157 and 197 (see figure 7)s of a bending respectively, and these two faces are protruding arch with respect to surperficial 46.

Bristle pack 155 has outside one row brush pieces 158 to 171, and two bundle hairs 172 and 173 on center line, and this two bundles hair is stretched fartherly from surface 46 compared with other pieces of bristle pack 155 and the bristle tuft of bristle pack 195.

With the bristle shown in the section line, be bristle shorter in the bristle pack 155 in Figure 15, their label is 175 to 184.

Bristle pack 195 has first row, 5 bundle hairs, 198, second row, 5 bundle hairs, 199 (bending towards front end), the 3rd row 5 bundle hairs 200 (more bending towards front end), the 3rd horizontally-arranged 3 bundle hairs the 201 and the 4th horizontally-arranged 2 bundle hairs 202. Pieces 164 and 165 is than pieces 202 length.

In this embodiment, curved surface 197 is made continuity advance in the bristle pack 155 by interior pieces 175 to 184 (band cross spider person in Figure 15).

The free end of these bristles is being followed dotted line 197A shown in Figure 15.As can be seen, this curved surface 197A at the front end place of this curved surface 197A, falls to surface 46 slightly, and line of bristles 198 is the longest bristles among the curved surface 197/197A.

In some variant (not shown)s of this embodiment, curved surface 197A can fall more significantly, or the peak of curved surface 197 can arrange 202 places at pieces, or the height point of curved surface 197/197A is on pieces 175,176.

In another variant, each the bundle hair in the bristle pack 195 and among the pieces row 175 to 184, all same long, thus only can form single curved surface, promptly by bristle 158 to 171 and 172 and 173 curved surfaces that form.

In addition, by in brush holder afterbody one side's the four horizontally-arranged pieces, outer pieces is pieces 161 and 168 in bristle pack 155, than pieces 175 and 176 length; Pieces 160 and 169 is than pieces 177 and 178 length; Pieces 159 and 170 is than pieces 179 to 181 length; And pieces 158 and 171 is than pieces 182 to 184 length.

Referring to Figure 16, the length of bristle configurations in plan view or side view, promptly the length of the bristle tooth contact jaw parallel with surperficial 46 is 9.2 units.100% of this length is formed by bristle, and during toothbrush, the tooth contact jaw of bristle is on the curve from side view.Bristle pack 155 accounts for 5.3 units, and bristle pack 195 also accounts for 3.6 units, and this two groups all are protruding arches.

When coming amount with surface 46 vertical directions, the bristle in the pieces 164 and 165 at the head one end place of bristle configurations highly is 3.8 units.When the direction vertical with surperficial 46 come amount, the bristle after those lean on most in pieces row 202 highly is 2.6 units.

The length ratio of long brush hairs and short bristles, thereby be 1.5: 1.

The 3rd embodiment of bristle configurations is shown among Figure 19 to 24, especially can be referring to Figure 21,22,23 and 24.

Can consider to allow bristle be divided into by flex point 216,236,256 and 276 and draw the 5 groups of bristles 215,235,255,275 and 295 that refer to, when from the side view toothbrush, these flex points and bristle pack are in continuous sine-shaped bristle tooth contact-making surface 207.

Bristle in this configuration is not arranged to the so much horizontally-arranged in that row of central axial line respectively arranges with periphery.

Bristle pack 215 has two pieces 218,219 that are close in first horizontally-arranged, then be two the edge pieces 220,221 in a horizontally-arranged, it then is a central pieces 222, then be two edge pieces 223 and 224 again, then central pieces 225 again, again and be two edge pieces 226,227.This group bristle has formed a protruding arch tooth contact-making surface 217.

Bristle pack 235 forms a recessed arch tooth contact-making surface 237.It is made up of the pieces 239,240 of 4 pieces of row (bending towards the place ahead) 238 and arrangement inwardly.

Bristle pack 255 forms a protruding arch tooth contact-making surface 255.It has 2 pieces of transversely arranging 258,259 inwardly.Then be one by 2 edge pieces and the horizontally-arranged 260 that central pieces is formed.Next be 2 pieces of arranging inwardly 261 and 262 again.Be the another pieces row 263 who is similar to pieces row 260 then.

Bristle pack 275 forms a recessed arch face 277.It has 2 pieces of arranging 264,265 more inwardly.Be as pieces row 260 then, but the wrong slightly pieces row 266 from the place ahead of interior pieces.

Bristle pack 295 forms a protruding arch face 297.It has 2 pieces of arranging 267,268 inwardly, be a pieces row 269 then as 266, next be 2 pieces 270,271 of more inside arrangement, getting off is pieces row 272 as 266 again, is 2 pieces 273,274 that are close to as 218 and 219 then.

Pieces 218,219 is than pieces 273 and 274 length.

Referring to Figure 22, the length of bristle configurations on plan view or side view, promptly the length of the bristle tooth contact jaw parallel with surperficial 46 is 8.9 units.100% of this length is formed by such bristle, and during from the side view toothbrush, the tooth contact jaw of these bristles is on the curve.Bristle pack 215 accounts for 2.7 units, and bristle pack 235 accounts for 1.3 units, and bristle pack 255 accounts for 1.9 units, and bristle tuft 275 accounts for 1.3 units, and bristle pack 295 accounts for 1.6 units.

Bristle pack 215,255 and 295 all is protruding arches, accounts for 6.2 units altogether.Bristle pack 235 and 275 is recessed arches, accounts for 2.6 units altogether.

Therefore, protruding arch is 6.2: 2.6 with the ratio of recessed arch, or 2.4: 1, or wideer 1.5: 1 to 3: 1 of scope.

Equally, arrange those several rows than the bristle among the short pieces row 380,410,430,450 and 470 at each, and the bristle in the pieces 480, identical length is together.

The bristle lengths (LL) of long brush hairs end the row 400,420,440,460 from surface 46 to pieces with the ratio of the bristle lengths (LS) of short bristles among the pieces row 380,410,430,450,470, is 1.15: 1.Or wideer 1.05: 1 to 1.5: 1 of scope, for example 1.1: 1 to 1.4: 1.

Bristle pack 355 has pieces 360 before the central authorities, at the side pieces 361 and 363 of a side, at the side pieces 362 and 364 of opposite side, and between pieces 363 and 364 also slight pieces 365 forward.The rear portion of these pieces also forms the part of bristle pack 375.

Can see clearly from Figure 29 and 30, pieces 363,365 and 364 is highly identical, and is slightly higher than the pieces among the pieces row 400,420,440 and 460.

These pieces 363,364,365 and higher pieces row 400 etc., the ratio of the height of the two is 1.04: 1, or wideer 1.02: 1 to 1.3: 1 of scope; Simultaneously, they and this ratio than undercoat bundle row 380,410 etc. are 1.2: 1, or wideer 1.1: 1 to 1.5: 1 of scope.

Bristle pack 375, by forming by the rear section and by the pieces row 379 of 3 pieces of pieces 363,365 and 364, these pieces have formed a recessed arch that faces toward the tooth contact-making surface backwards.

Referring to Figure 28, the length of bristle configurations in plan view or side view, promptly the length of the bristle tooth contact jaw parallel with surperficial 46 is 8.7 units.16% of this length, bristle tooth contact jaw is in a bristle on the curve and forms by from the side view toothbrush time, and bristle pack 355 accounts for 1.4 units, and bristle pack 375 accounts for 0.9 unit, and 355 be protruding arch, and 375 is recessed arch.Therefore, protruding arch is 1.4: 0.9 with the ratio of recessed arch, or 1.55: 1, or wideer 1: 1 to 2: 1 of scope.

When the direction vertical with surperficial 46 come amount, the bristle height of the pieces 364,365,363 of close bristle configurations head one end is 3.6 units.When the direction vertical with surperficial 46 come amount, the bristle height in the pieces 380 is 2.9 units.

Therefore, long brush hairs and the two length ratio of short bristles are 1.25: 1.

Pieces row 379, by 2 side pieces 372 and 374, and the position is only slightly than pieces 372 and 374 forward central pieces 373 compositions.These pieces 372 and 374, position are also inner than pieces 363 and 364 slightly.

That group pieces 360 to 365 and pieces row 379, as follows with the separation situation of castellated bristle pack 380 to 480:

379 and 380 of pieces rows have a space (A);

380 and 400 of pieces rows have a space (B);

(B) less than (A);

400 and 410 of pieces rows have a space (C);

(C) or (B) less than (A);

Do not have the space between the pieces row 410 and 420, they are contacting;

420 and 430 of pieces rows have a space (D);

(D) or (B) similar in appearance to (A);

430 and 440 of pieces rows do not have the space, and they become the finger-like combination;

440 and 450 of pieces rows do not have the space, and they are contacting;

450 and 460 of pieces rows do not have the space, and they become the finger-like combination;

460 and 470 of pieces rows, or pieces arranges 470 and 480 of the bristles of back, do not have the space, and they are contacting.

Figure 31 and 32 is the views similar in appearance to Fig. 6 and 7, but demonstration is the bristle configurations of the first change type of embodiment among Figure 25.

Figure 31 and 32, the first change type of bristle shape the 4th embodiment shown in demonstration Figure 25 to 30.

Can consider to allow bristle by the lines in Figure 31 and 32 356 and 376, be divided into 3 bristle pack 355,375 and 395, so that explanation.When side view is seen toothbrush, the end of bristle in the bristle pack 355 forms a protruding arching face 357.When side view is seen toothbrush, the end of bristle in the bristle pack 375 forms a recessed arching face 377.Curve 357 and 377 smoothly joins, the flex point place of lines 356 between two curves.Bristle pack 395 then by than long brush hairs 400,420,440,460 and than a few horizontally-arranged pieces of replacing of short bristles 380,410,430 and 450, has formed a castellated tooth contact-making surface 397.

In that 4 row of every row became mildewed bundle row 400,420,440,460, bristle lengths was all identical, was the bristle of pieces 361,362,363 and 364 but be shorter than in the bristle pack 355 long brush hairs slightly.

Equally, arrange those several rows than the bristle among the undercoat bundle row 380,410,430 and 450 at each, identical length together.

The bristle lengths (LL) of long brush hairs end the row 400,420,440,460 from surface 46 to pieces with the ratio of the bristle lengths (LS) of short bristles from pieces row 380,410,430,450, is 1.15: 1.Or wideer 1.05: 1 to 1.5: 1 of scope, for example 1.1: 1 to 1.4: 1.

Bristle pack 355 has a pair of transversely arranged pieces 361 and 363, and 3 transversely arranged pieces 363,364 and 365.

Can see clearly from Figure 32, the height of long brush hairs is identical in the pieces 361 to 365, and is higher than the pieces among the pieces row 400,420,440 and 460.

Pieces 361,365 and higher pieces row 400 etc., the ratio of the two bristle height is 1.14: 1, or wideer 1.04: 1 to 1.4: 1 of scope; Simultaneously, they and this ratio of shorter pieces row 380,410 etc. are 1.28: 1, or wideer 1.2: 1 to 1.6: 1 of scope.

Bristle pack 375 is that a pieces row 379 who arranges forms by forming 3 pieces 372,373 and 374 that face toward the recessed arch of tooth contact-making surface backwards.

To change place of pieces shape, at the front end of head.

That pieces 360 of central authorities has saved.Pieces 361 and 362 is keeping.It is a horizontally-arranged at a right angle that pieces 363,365 and 364 has been aligned to the head longitudinal axis.It is a horizontally-arranged at a right angle that pieces 372,373 and 374 on the pieces row 379 has been aligned to the head longitudinal axis.Pieces 372 and 374 is by horizontal outer being moved, thereby they are more outer than pieces 363 and 364 with respect to longitudinal axis.

Bristle 361,362,363,364,372,373 and 374 constitutes a quadrangle.

Pieces group 361 to 365 and 372 to 374 is as follows with the separation situation of castellated bristle pack 380 to 480:

Between each row tangible space is arranged all;

The space (A) that one about 5.5 units are arranged between the pieces row 379 and 390;

Space (B) between the pieces row 380 and 400 is 5.5 units.

Space (C) between the pieces row 400 and 410 is 5.5 units, remaining each space (D), (E), (F), (G) and (H) be this unit.

When the ratio of A: B was 1.1: 1, space (B) can be 5 units.

Referring to Figure 32, in the length of the bristle configurations on the plan view or on side view, promptly be parallel to the length of the bristle tooth contact jaw on surface 46, be 7.4 units.24% of this length is when from the side view toothbrush, and bristle tooth contact jaw is in that those bristles on the curve form.Bristle pack 355 accounts for 1.1 units, and bristle pack 375 accounts for 0.8 unit, and 355 be protruding arch and 375 are recessed arches.Therefore, protruding arch is 1.4: 1 with the ratio of recessed arch, or wideer 1: 1 to 2: 1 of scope.

When coming amount,, be 3.2 units near the height of high bristle in the pieces 361 to 365 of bristle configurations head one end with surface 46 vertical directions.When the direction vertical with surperficial 46 come amount, the height of bristle is 2.9 units in the pieces 380.

Therefore, long and the two length ratio of short bristles of the longest brush is 1.28: 1.

Referring to Figure 33 and 34, shown the second change type of H15RV1 the 4th embodiment among the figure.It is similar in appearance to the first change type.The pieces configuration is identical, but has any different at the end of pieces 361 to 365 and 372 to 374. Pieces 361 and 362 is not the summit that bends towards up from the front portion on the trailing edge, but is inclined to a unbending transversal plane 357A in front of facing toward up and backwards.

Pieces 363,365 and 364 is not downwards toward the trailing edge bending, but downwards and recede into a unbending transversal plane 357B facing to the back from the vertex of front portion.Therefore, pieces 361,362 and 363 to 365 just forms inverted V-shaped tooth contact-making surface 357A and 357B, and the angle of each face in these contact-making surfaces is about 45 ° to the right angle, or wideer 30 ° to 60 ° of scope.

The end of the pieces 372 to 374 among the pieces row 379 is inclined to unbending transversal plane 377 facing to the back.Plane 377 is continuities of face 357B.

At this moment, anterior bristle pack 355 is made up of pieces 361 and 362, and second bristle pack 375 is made up of pieces 363,364 and 365 and 372,373 and 374, and lines 356 are between first row and the second row's pieces.
