[0003]

In these conventional toothbrushes, hair bundles that are adjacent to each other in the longitudinal direction of the bristle portion are arranged or cut so as to form an inverted V-shaped hair bundle or a brush surface.
The directionality is determined when brushing teeth, that is, when the toothbrush is moved up or down or left or right, the tip of the brush enters the interdental area for cleaning, but when the toothbrush is moved in the other direction, the tip of the brush is moved. It does not enter, and it is difficult to enter, so it has the drawback that it cannot remove plaque efficiently.In addition, there is a bias in the function side such as brushing operation is difficult to brush other parts because the brushing part and the brushing method are limited. Therefore, it does not necessarily match the brush's cleaning surface, and cleaning cannot be performed to remove plaque in the interdental area.Furthermore, conventional toothbrushes for cleaning interdental areas have different brushing methods and cleaning methods depending on the shape of the brush. When the area is limited, the crested tips can efficiently enter the interdental area for cleaning, but this effect appears only when the rolling brush method is used. , Depending on the shape of the brush There was a tooth neck, a problem that brushing is difficult to make the occlusal surface. On the other hand, when cleaning the occlusal surface and smooth surface of the tooth, the vertical flocked hair bundle has a better cleaning power than the inverted V-shaped bristle bundle, but it is difficult to clean the interdental part,
Assuming that the bristles of V-shape and the bristles of vertical bristles are mixed, if the brush length of the bristles of bristles is equal to or longer than the brush height of the bunch of inverted V-shaped bristles, the tips of the bristles of the bristled V-shaped bristles are located between the teeth. However, there is a drawback that the effect of cleaning the interdental part is reduced and the effect of removing plaque is reduced.

The present invention eliminates these conventional problems,
Regardless of the brushing operation, it is possible to greatly improve the interdental cleaning effect and the cleaning effect on the smooth surface of the teeth, etc. It is intended to provide a toothbrush that can effectively remove plaque even at the part.

[0005]

According to the present invention, a plurality of brushes are provided at appropriate intervals in a longitudinal direction or a width direction of a head portion in order to implant a hair bundle in the head portion of a toothbrush. In a toothbrush having a plurality of bristles, which are formed in a mountain shape by inclining the bristles of each bristles to each other, the bristles being inclined with respect to the flocking surface of the head part, in the longitudinal direction of the head part. The first angled tufted hair portion that is inclined and the second angled tufted hair portion that is inclined in the width direction of the head portion are arranged in a mixed manner.

[0006]

[Function] No matter which direction the toothbrush is moved during brushing to brush the teeth, the brush tip easily enters the interdental part,
Moreover, the spacing between the crests of the brush tip easily matches the interdental part between the teeth, and the plaque in the interdental part can be removed accurately, and the interdental part can be effectively cleaned. Also, it can effectively remove plaque adhering to the molar fissures and the interproximal part, and it can brush the areas where the tips of hair were hard to reach, which is less likely to cause hair fall and durability. Can also be used as a rich toothbrush.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, a plurality of brushes are used in the longitudinal direction or the width direction of the head portion 1 to implant a hair bundle in the head portion 1 of the toothbrush. Adjacent tufts 2 and 2 provided with appropriate intervals in
The Tabake portion formed in Yamagata fit asked the bristles of the respective tuft is inclined with respect to planted surface 1 ₁ of the head portion 1 a plurality toothbrush head portion 1, of the head portion 1 A toothbrush is formed by mixing and arranging the first angled bristles 3 inclined in the longitudinal direction and the second angled bristles 4 inclined in the width direction of the head part 1.

Then, as the two adjacent hair bundles 2,
Inclined flocked surface 1 ₁ of the head portion 1, for example 1-5 ° preferably implanted at a tilt angle in the range of 3 degrees before and after, Yamagata Tabake of inverted V-shape together tuft of the capillary bundles 2 are more The parts 3 and 4 are formed, but when the brush height is 10 to 12 mm and the bristle hole pitch is 2.5 to 3.0 mm, the tops of the hair bundles 2 come into contact to form a clean inverted V-shape. can, because increases the bristles penetrate performance to gullet, also, the top shape of the tufts 2 is also straight cut parallel horizontal plane flocking surface 1 _1, or a chevron slope of the mountain cutting cut. The thickness of the bristles of the angled bundles 3 and 4 is 5 to 10 mils, preferably 8 mils, and the height is 1
1 to 12 mm is practically suitable, and a toothbrush with an ordinary hardness can be used. The brush material is nylon, PBT, etc., and the shape of the tip of one brush is round, tapered, super tapered, etc. Good. When manufacturing the angled bristles 3 and 4, since the angle of inclination of the bunch 2 is 5 degrees or less, the cost of the molding die can be dealt with in the same manner as in the case of the flocked holes of the vertical bunch, and the cost is increased. In the flocking work, if the brush and the flat wire are press-fitted in the vertical direction, the hair can be naturally angled along the flocking hole and the production can be performed without increasing the cost.

As the flocking of the head portion 1, the vertical bristle tufts 5 which are planted in the vertical direction and whose flocking height is lower than that of the chevron-shaped tufts 3 and 4 are mixed to obtain the advantages of the tufted tufts. It is preferable to have the advantages of a vertical tuft and also to complement each other's drawbacks so that the tips of the chevron-shaped tufts 3 and 4 reach the interdental part stably and The tip of the vertical bristle bundle 5 that contacts the tooth surface and gums does not interfere with the cleaning of the interdental part, so that the interdental part and the smooth surface or occlusal surface of the tooth can be effectively cleaned at the same time. In this case, it is preferable that the angled hair bundles 3 and 4 and the vertical hair bundles 5 are arranged as evenly as possible on the head portion 1 so that the cleaning effect is uniform.

Further, the second chevron-shaped tufted bristle portion 4 intersects with the longitudinal direction of the head portion 1 as a reference line in a direction from 0 degree (not including 0 degree) to 90 degrees from the reference line. The brush of the inverted V-shaped bristle bristle unit is interdental regardless of the direction in which the toothbrush is moved. I am going to enter.

In the example of FIG. 1, the first chevron bundles 3 groups arranged in parallel to the longitudinal direction of the head portion 1 and the second chevron bundles 4 groups arranged in the direction perpendicular to the longitudinal direction alternate. Deployed to
The third inclined to the longitudinal direction at the tip position of the head portion 1
It is provided with the angled bundles 6.

In the example of FIG. 2, the first chevron bundles 3 and the second chevron bundles 4 of the head portion 1 which are orthogonally arranged in the longitudinal direction and the width direction are arranged alternately in a zigzag pattern. At the tip position of the portion 1, the inclined bristle bundles 7 are deviated in phase so as to form a flocked brush cleaning surface which is arranged so that the tips of the bristles are arranged in a zigzag state in a staggered manner.

In the example of FIG. 3, vertical bristle tufts 5 are alternately interposed between the first chevron-shaped tufted hair portions 3 and the second chevron-shaped tufted hair portions 4 which are orthogonally arranged in the longitudinal direction and the width direction of the head portion 1. It has been deployed to enable efficient cleaning of interdental, occlusal, and smooth surfaces.

In FIG. 4, the third V-shaped bristle bristle portion 6 is arranged at the tip position of the head portion 1 in the inverted V-shaped flocking unit similar to the example of FIG.

In the example of FIG. 5, vertical bristles 5 are arranged in the width direction at the center of the head portion 1, and there are two rows of second chevron-shaped bristles 4 and four rows at symmetrical positions about the center. A single chevron-shaped bundle 3 is arranged, and a vertical bundle 5 is further provided in one row to form a cleaning surface.

In the embodiment shown in FIG. 6, the first chevron-shaped tufts 3 and one vertical tuft 5 on both sides thereof are arranged at the central position of the head portion 1, and the vertical tufts 5 are arranged symmetrically about the center of the first tufted tufts 5. A plurality of rows of third chevron-shaped bundles 6 are provided on both sides with the center as the center to form a cleaning surface.

In the embodiment shown in FIG. 7, one row of vertical bristle tufts 5 is provided at the front and rear ends of the head portion 1, and two rows of the second chevron-shaped tufted hair portions 3 and one on both sides of the second chevron-shaped tufted hair portion 4 are provided. Patterns with vertical bristle bundles 5 are alternately arranged in a zigzag pattern to form a cleaning surface so that the brush enters the interdental part regardless of the direction of the toothbrush, and the occlusal surface and smooth surface of the teeth The cleaning effect on the surface is also enhanced.

In this case, in order to bring the tips of the hair bundles close to each other, the hair bundles are made to face each other with respect to the plane of the head, or the inclined hair bundles 2 are slanted in the same direction, but the hairs in the vertical direction are arranged. A combination of a tuft and a tuft in the slanting direction may be used, and in some cases, a combination of the tufts of tufts on a diagonal line of the tufts to be arranged may be combined as one unit. The tips are aligned and aligned in the longitudinal direction of the head portion 1, the width direction, or another diagonal direction. In addition, even if the angle-shaped cuts are slightly out of phase in each row of the flocked part and the tooth-to-tooth spacing is different, any of the crests will come into contact with the interdental part during tooth brushing. It is also possible to thoroughly clean the part. In addition, the bristles are formed by bundling nylon bristles in the bristling holes provided in the head part 1 to form a bristling part, but if necessary, mix natural bristles with synthetic bristles such as nylon bristles. It can also be planted. The size of the head portion 1 is preferably such that it can be moved freely in the mouth and the plaque adhering to the molar fissure portion and the interproximal portion is effectively removed.
