In the third embodiment, not shown, the handle of the second embodiment is provided with ribs similar to the ribs 45 on the mat 41 but not required for the same number or the same inclination or all the surfaces 42, 43, 44. However, the installation having the same ribs 45 as in the first embodiment integrally molded to the handle is good.

In the head 50, the bristle structure of the first embodiment is shown in Figs. As shown in FIG. 7, the head has three groups of bristles tough 55, 75, 95. These are shown as planes in FIG. 6 by transversal lines 56 and 76. The group 55 provides a tooth engaging surface 57 that is convex with respect to the surface 46 of the head of the handle when the toothbrush is viewed sideways. On the surface 46 a tough bristles are planted.

Group 75 provides a tooth engaging surface 77 that is concave with respect to surface 46 when the toothbrush is viewed sideways.

The group 75 has a central front outer turf 60, side toughs 61, 62, 63; 64, 65, 66, and two centerline toughs 67, 68. Group 75 has five transverse row toughs 78, 79, 80, 81, 82. The first three rows 78, 79, 80 have four toughs each, and the last two rows 81, 82 have five toughs each.

The tooth contacting end of the tough 78 is further away from the face 46 than the ends of the tough 63, 68, 66 but at approximately the same level as the tough 67, 62, 65.

Group 95 provides a tooth engaging surface 97 that is approximately similar in appearance to surface 57. Group 95 has a first row of five tufts 98, a second row of four tufts 99, two side tufts 100 and 101 and a central rear turf 102. The tough 98 is shorter than the tough in row 82, but the tough in row 99 is about the same height as the tough in row 82.

Thus, the tooth engagement surface provided by the bristles as a whole is wavy or sinusoidal, but end tough of adjacent groups, e.g. rows 63, 68, 66 of group 55 and rows 78 of group 75 ) And the row 82 of the group 75 and the row 98 of the group 95 is not a continuous plane with a brake at the level.

With reference to FIG. 6, the length of the bristle structure, i. E., In the plane or side face, is parallel to the surface 46 of the tooth contacting end of the bristles in 8.8 units. This 100% length is provided by the bristles, which are curved tooth contact ends when the toothbrush is viewed sideways. Group 55 occupies 2.5 units, group 95 occupies 2.5 units, and all are convex. Group 75 occupies 3.5 units and is concave. Thus, the ratio of convex to concave is 5: 3.5 or 1.4: 1 or more broadly 1: 1 to 2: 1.

The bristle structure of the second embodiment is specifically illustrated in FIGS. 10-18 with reference to FIGS. 15, 16 and 17.

The bristles consist of two groups 155, 195 separated in FIG. 15 by line 156.

Each group provides curved tooth contact surfaces 157, 197 that are all convex (FIG. 7) with respect to surface 46.

The group 155 is formed from the outer rows of the two bristles 172, 173 and the bristles 158-171 at the centerline where the bristles of the group 195 and the remaining bristles of the group 155 are reached farther. Have

The bristles 175 to 184, denoted cross-sectional in FIG. 15, are the short bristles of group 155.

Group 195 includes five tufts of first row 198, five tufts of second row 199 (bends toward the front end), and four tufts of third row 200 (front) Bent toward the end), a third row of three tufts 201 and a fourth row of two tufts 202. Tough 164 and 165 are longer than tough 202.

In this embodiment, the curved surface 197 is continuous in the direction toward the group 155 by the inner tough 175-184 (crossed in FIG. 15).

The free end of the bristles follows the dotted line 197A shown in FIG. This curved surface 197A bends slightly downward towards its surface 46 at its front end, and the row 198 is the longest bristles contained in the surface 197 / 197A.

In a variation of this embodiment (not shown), the surface 197A can be bent more significantly downward or the surface 197 can have a peak in the row 202 or the surface 197 / 197A is tough You can have a high at (175, 176).

In another variation, the toughness in groups 195 and arrays 175-184 may both be the same length so that only a single curved surface is provided by bristles 158-171, 172, 173.

In addition to the four rows at the handle ends of the group 155, the outer bristles, ie the tough 161, 168, are longer than the tough 175, 176; Tough (160, 169) is longer than tough (177, 178); Tough 159, 170 are longer than tough 179-181; And the tough 158, 171 are longer than the tough 182-184.

Referring to FIG. 16, the length of the bristle structure, ie when viewed in plan or side view, is the length parallel to the face 46 of the tooth contacting end of the bristles in 9.2 units. This length of 100% is provided by the bristles, which are curved tooth contact ends when the toothbrush is viewed sideways. Group 155 occupies 5.3 units, group 195 occupies 3.6 units, and all are convex.

The height of the bristles in the tough 164, 165 at the head end of the bristle structure is 3.8 units when measured in a direction orthogonal to the surface 46. The height of the rearmost bristles in the row of tough 202 is 2.6 units when measured in the direction orthogonal to the surface 46.

The ratio of longest bristles to shortest bristles is 1.5: 1.

The bristle structure of the third embodiment is specifically shown in FIGS. 19 to 24 with reference to FIGS. 21 to 24.

The bristles are divided into five groups (215, 235, 255) on the basis of the bend points (216, 236, 256, 276) at the tooth contact surface (207) of the bristle in sinusoidal continuous wave form when viewed from the side of the toothbrush. 275, 295).

The bristles in this structure are aligned, such as rows in the circumferential row and in the central axis row.

The group 215 has two toughs 218, 219 alongside the first row, then two corner troughs 220, 221 again in the row, then the center tough 222, then two edge tough 223, 224, then center turf 225, followed by two corner tough 226, 227. This group provides a convex tooth contact surface 217.

Group 235 provides a concave tooth contact surface 237. It is made from four tufted rows 238 (bending forward) and two inwardly disposed tufts 239 and 240.

Group 255 provides a convex tooth contact surface 257. It has two inwardly arranged turf 258, 259. The row 260 then consists of two edge tough and center tough. Next, two inwardly disposed tough 261 and 262 are disposed. Next, another tough 263 is provided, such as column 260.

Group 275 provides a concave surface 277. The group has two or more inwardly arranged tough 264, 265. Next, column 266 has an internal tough similar to column 260 but slightly displaced forward.

Group 295 provides a convex surface 297. The group has two inwardly disposed tufts 267 and 268, and column 269 is similar to row 266 and has two or more inwardly disposed tufts 270 and 271. 272 is similar to row 266, and two side by side tufts 273 and 274 are similar to tough 218 and 219.

Tough 218 and 219 are longer than tough 273 and 274.

Referring to FIG. 22, the length of the bristle structure, ie, the length, when viewed from the side face, is parallel to the surface 46 of the tooth contacting end of the bristles in a 8.9 unit. This length of 100% is provided by the bristles of the tooth contact end which are curved when the toothbrush is viewed sideways. Group 215 occupies 2.7 units, group 235 occupies 1.3 units, group 255 occupies 1.9 units, group 275 occupies 1.3 units and group 295 occupies 1.6 units To occupy.

Groups 215, 255 and 295 are convex and occupy 6.2 units. Groups 235 and 275 are concave and occupy 2.6 units.

The ratio of the convex to the concave is 6.2: 2.6 or 2.4: 1 or more broadly 1.5: 1 to 3: 1.

The height of the bristles to the tough 222, 220, 224 proximate the head end of the bristle structure is 3.2 units as measured in a direction perpendicular to the surface 46. The height of the rearmost bristles in rows of tough 273 and 274 is 2.1 units when measured in the direction perpendicular to the surface 46.

Therefore, the ratio of the longest bristles to the shortest bristles is 1.5: 1.

The bristle structure of the fourth embodiment is shown in FIGS. 25 to 30.

The bristles are considered to consist of three groups 355 and 375 separated by lines 356 and 376 in FIGS. 27 and 28 for ease of explanation. The ends of the bristles in group 355 provide a convexly curved surface 357 when the toothbrush is viewed sideways. The bristle end in group 375 provides a concave curved face 377 when the toothbrush is viewed sideways. Curves 357 and 377 are curves of gentle flow inward to each other, and lines 356 are at the bending point between the curves. The group 395 is a castle given by a replaceable row of single central posterior tough 480, short bristles 380, 410, 430, 450, 470 and long bristles 400, 420, 440, 460. It provides a tooth contact surface 397 constructed as.

In each of the four long rows 400, 420, 440, 460, the bristles are of the longest bristles in the group 355, i.e. slightly shorter than the bristles in the tough 361, 362, 365.

Similarly, the bristles and tough 480 in each of the thermal insulations 380, 410, 430, 450, 470 are all of the same length.

Bristles from the surface 46 to the ends of the bristle long bristles in rows 400, 420, 440, 460 for the bristle length LS for rows 380, 410, 430, 450, 470 The ratio of length LL is 1.15: 1. More broadly in the range 1.05: 1 to 1.5: 1, for example 1.1: 1 to 1.4: 1.

The group 35 is centered between the central front turf 360 and side tufts 361 and 363 on one side and side tufts 362 and 364 on the other side, and slightly forward of tufts 363 and 364. It has a tough 365. The rear of the tough also provides part of the group 375.

As readily seen from FIGS. 29 and 30, the tough 363, 365, 364 are the same height and slightly longer than the tough in rows 400, 420, 440, 460.

The ratio of the heights of the tough 363, 364, 365 to the long string 400 is 1.04: 1 or more broadly 1.02: 1 to 1.3: 1; On the other hand, the ratio for insulation 380 and 410 is 1.2: 1 or more broadly 1.1: 1 to 1.5: 1.

Group 375 consists of three tough rows 379 and the rearmost portions of tough 363, 365, 364 that provide a concave back facing tooth contact surface.

With reference to FIG. 28, the length of the bristle structure, ie the length, when viewed in plan or side elevation, is parallel to the surface 46 of the tooth contacting end of the bristles in 8.7 units. This length of 16% is provided by the bristles of the tooth contact ends that are curved when the toothbrush is viewed sideways, group 355 occupies 1.4 units, group 375 occupies 0.9 units, 355 is convex and group 375 is concave. The ratio of the convex to the concave is 1.4: 0.9 or 1.55: 1 or more broadly 1: 1 to 2: 1.

The bristles height at the tough 364, 365, 363 proximate the head end of the bristle structure is 3.6 units when measured in a direction perpendicular to the surface 46. The height of the bristles in the tough 380 is 2.9 units when measured in a direction perpendicular to the surface 46.

Therefore, the ratio of the longest bristles to the shortest bristles is 1.25: 1.

Row 379 consists of a central tuft 373 and two side tufts 372 and 374 located in the significantly smaller forward direction of the tufts 372 and 374. The tough 372 and 374 are also located in the significantly smaller interior of the tough 363 and 364.

Separation of groups of rows 379 and toughs 360-365 from gender groups 380-480 is as follows:

There is a gap A between rows 379 and 380;

The center bristle tough 360 is omitted. Tough 361 and 362 are retained. Tough 363, 365, 364 are aligned to form a row at right angles to the longitudinal axis of the head. Tough 372, 373, 374 over rows 379 are aligned to form a transverse row at right angles to the longitudinal axis of the head. The tough 372, 374 are moved laterally outward so that they are positioned outward of the tough 363, 364 with respect to the longitudinal axis.

The bristles 361-364, 372, 373, and 374 form four sides.

The separation of the groups of tough 361-365, 372-374 from the sexual groups 380-480 is as follows:

There is a clear gap between each row;

There is a gap A between rows 379 and 380 of about 5.5 units;

The gap B between rows 380 and 400 is 5.5 units;

The gap (C) between rows 400 and 410 is five units as in the remaining gaps (D), (E), (F), (G), and (H).

Optionally, the gap B is 5 units if the ratio A: B is 1.1: 1.

Referring to FIG. 32, the length of the bristle structure, ie parallel to the surface 46 of the tooth contacting end of the bristles when viewed in plan or side elevation, is 7.4 units. This length of 24% is provided by the bristles of the tooth contact end which are curved when the toothbrush is viewed sideways. Group 355 occupies 1.1 units, group 375 occupies 0.8 units, group 355 is convex and group 375 is concave. The ratio of the convex to the concave is 1.4: 1 or more broadly 1: 1 to 2: 1.

The highest bristle height in the tough 361-365 proximate the head end of the bristle structure is 3.2 units when measured in a direction perpendicular to the surface 46. The height of the bristles in the tough 380 is 2.9 units when measured in a direction perpendicular to the surface 46.

Therefore, the ratio of the longest bristles to the shortest bristles is 1.28: 1.
