Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a multi-sided toothbrush.

More specifically, the present invention can simultaneously polish the anterior and posterior surfaces of either the upper and lower dentition, or the anterior, posterior, and occlusal surfaces, or even the anterior, posterior, and occlusal surfaces of the upper and lower dentition. The present invention relates to a multifaceted toothbrush.

[Prior Art] Various types of toothbrushes have been manufactured for brushing only one side of the dentition, but no toothbrush has been manufactured or reprinted for brushing the front, back and occlusal surfaces of the teeth at once. do not have.

Brushing teeth is necessary for maintaining health, but brushing teeth is a tedious task, and everyone wants to do it quickly and efficiently.

A toothbrush that brushes the front, rear, and interlocking surfaces of the teeth at once is described in Japanese Patent Laid-Open No. 55-5654. This toothbrush has a groove-shaped bristles surface, and vertical bristles are planted on the bottom surface toward the front and back of the center, and horizontal rows of bristles are planted facing each other on the inner surfaces of both walls of the groove. It is something.

With this toothbrush, the positions of the tips of the bristles are fixed, so it is not always possible to effectively brush teeth of different thicknesses and lengths. Furthermore, since the depth of the groove is constant, the rows of bristles do not reach the gingiva, making it impossible to brush the gingiva at the same time as brushing the teeth.

[Problems to be solved by the invention] As mentioned above, most conventional toothbrushes are used to brush one side of the teeth, and even if they are used to brush each side of the teeth at once, there are The effects of this are unsatisfactory.

The present invention has been made to solve these conventional problems. That is, the present invention provides a multi-sided toothpaste brush that can brush the front, back, and occlusal surfaces of the teeth at once, making tooth brushing more effective and shortening the tooth brushing time.

Furthermore, the present invention provides a multifaceted toothbrush that can brush the front, back, and occlusal surfaces of the upper and lower tooth rows at once, which was previously impossible.

[Means for Solving the Problems] The multifaceted toothpaste brush of the present invention includes a handle, a first bristles integrally formed at the tip of the handle, and a first brush comprising bristles implanted in the first bristles. , and a branch portion attached in a fork shape near the tip of the handle, a second flocked portion integrally formed at the tip of the branch portion, and a second bristles implanted in the second flocked portion.
Consists of brushes.

The above-mentioned branch portion is preferably made of a flat member, and in that case, it is attached so that the cross section of the branch portion is perpendicular to the attachment surface of the handle. The branch can also be attached to the handle by means of a pivot and an elastic member.

At least one of the bristles of the first and second bristles is formed by a plurality of rows of short linear tufts and long tufts whose tips are curved toward the tips of the short tufts. By doing so, you can also polish the occlusal surfaces of your teeth.
.

Furthermore, the bristles of the first and second bristles are formed by two rows of long hair tufts whose tips are curved outward in opposite directions, and a plurality of rows of short hair tufts planted outside the rows of the long hair tufts. By doing so, the front, rear and occlusal surfaces of the upper and lower tooth rows can be polished at the same time.

Furthermore, instead of the bristles, various protrusions can be attached to the bristle implants to be used for gingival pine surge.

[Function] In the multi-sided toothpaste brush of the present invention, the bristles of the first brush and the bristles of the second brush face each other, and the row of teeth is sandwiched between both bristles, so that the front and back surfaces of the teeth can be brushed at the same time. be able to. Furthermore, by forming the bristles as described above with multiple rows of short hair tufts and long hair tufts with curved tips,
The bristles can be brought into contact not only with the front and rear surfaces of the teeth but also with the occlusal surfaces at the same time.

Furthermore, in one embodiment of the toothpaste brush of the present invention, the bristles are implanted so as to wrap around the upper and lower teeth at the same time.
The front, back and occlusal surfaces of the upper and lower tooth rows can be brushed at the same time, making tooth brushing more efficient.

[Example] Hereinafter, the multi-sided toothpaste brush of the present invention will be described in more detail with regard to the illustrated example.

1 to 4 show basic embodiments of the multifaceted toothbrush of the present invention.

The multifaceted toothpaste brush 1 includes a handle 2, a first bristle part 3 integrally formed at the tip of the handle 2 (on the right side of the drawing), a first brush 5 consisting of bristles 4, and a bifurcated toothbrush 5 near the tip of the handle 2. It consists of a second brush 9 consisting of branches 6, second bristle parts 7 and bristles 8 attached in the form of a shape. Note that the reference numeral 10 in FIG.
are human teeth.

The handle 2, first bristle part 3, branch part 6, and second bristle part 7 of the multifaceted toothbrush 1 can be made of a relatively hard and elastic synthetic resin, like a normal toothbrush. The shape of the handle 2 is usually a rounded flat quadrangular prism shape, but it may also be elliptical or cylindrical.A first flocked part 3 is integrally formed on the tip side of the handle 2. The bristles 4 are implanted on one side. The shape, material, etc. of these brushes are almost the same as those of a normal toothbrush.

A branch 6 is attached in a forked manner near the tip of the handle 2 and on the same side as the bristles 4. When brushing your teeth, this branch 6 may get caught between the upper and lower rows of teeth and touch your teeth, so the branch 6
It is better for the branch part 6 to be thin.However, since the branch part 6 also plays the role of elastically pressing the bristles 8 of the second brush 9 against the back side of the teeth 10, it cannot be made too thick.Therefore, the branch part 6 should be .

It is preferable to make it flat as shown in the cross section in FIG.

Further, the branch portion 6 may be formed integrally with the handle 2, but it may also be formed separately and attached to the handle 2 by an appropriate method such as gluing, fusing, or fitting. It is also possible to attach by means of a pivot and an elastic member as in the embodiment described later.

A second bristle-planted portion 7 is integrally formed at the tip of the branch portion 6, and bristles 8 are planted on the surface of the second bristle-planted portion 7 that faces the bristles 4.

The gap D between the bristles 4 and the bristles 8 (FIG. 2) is smaller than the thickness of the tooth so that the elasticity of the branch 6 can sandwich the tooth.

In reality, when the tooth enters between the bristles 4 and 8, both bristles are bent and the branches 6 are pushed apart, so that the bristles 4 and 8 face each other and are in contact with each other. Good too.

Figures 5 and 6 show the configuration of bristles 4 and bristles 8 for simultaneously brushing the anterior, posterior and occlusal surfaces of the teeth. The bristles 4 consist of a short straight ovary 12 and a long tuft 3 whose tip is curved toward the tip of the short ovary 12. Also,
Similarly, the bristles 8 are composed of a straight short ovary 14 and a long ovary 15 whose tip is curved toward the tip of the short ovary 14.

However, if all the tufts on one side (the upper side in FIG. 5) of the bristles 4 and 8 are long ovaries, they will collide with each other, so as shown in FIG. It is desirable to arrange them alternately and to have an alternating relationship with the workshops of the opposing flocking section. However, it is also possible to implant continuous long ovaries in only one or both of the first flocked part 3 or the second flocked part 7. By using the multi-sided toothpaste brush 1 having such a characteristic brush, it is possible to simultaneously brush not only the front and rear surfaces of the teeth 10 but also the 0* joint surface 16, as shown in FIG. 6B.

In addition, in the case of front teeth without an interlocking surface, as shown in Fig. 6C, the long ovary 13 and 15 are pushed and bent by the tip of the tooth and escape, coming into contact with the front and back surfaces of the tooth 10 and having a polishing effect. .

FIG. 7 shows another embodiment of the bristles used in the multifaceted toothbrush 1 of the present invention. In the embodiment shown in FIG. 7A,
Both side parts of the bristles 4 and 8 are lengthened along the longitudinal direction of the first bristles 3 and the second bristles 7, and in this case, it is preferable to use slightly softer bristles 4 and 8. When 8 is formed into such a shape, as shown in FIG. 7B, the long tufts of bristles 4 and 8 are bent and spread by the pressing force when brushing teeth, making it possible to brush teeth over a wide area. Yes. Since the contact range of the 5 ovary is widened, it is suitable because it can provide a tooth brushing action and also serve as a gingival massage.

The ovary shown in FIG. 7C has the center portions of the bristles 4 and 8 lengthened along the longitudinal direction of the first bristle part 3 and the second bristle part 7, and in this case, the tip of the tooth Depending on the purpose, you can brush particularly strongly the areas needed, such as the middle part of the tooth, the middle part of the tooth, or the boundary between the tooth and the gums.

The multifaceted toothpaste brush 1 shown in FIG. 8 has a gap between the bristles 4 and bristles 8 curved along the longitudinal direction of the first bristle part 3 and the second bristle part 7.

In reality, the radius of curvature of the gap is approximately the same as the radius of curvature of the tooth row, and is suitably approximately 3 cm to 5 cm, but is not limited to this.

When you use such multi-sided toothpaste brush 1.

Because the tip of the ovary fits well into the tooth row, teeth can be brushed even more quickly and effectively.

The multifaceted toothbrush 1 of the present invention includes bristles 4 and bristles 8.
Instead, a wart-like projection piece 17 for gingival pine surge as shown in FIGS. 9A and 9B may be attached. In addition,
The drawing shows an example of the first flocked part on one side, but the second
The same applies to the flocked portion. In addition, the wart-like projection 1
In addition to 7, for example, as shown in FIG.
Fig. 10B) or long and short rod-shaped projection pieces 20 (Fig. 10C)
), etc., can be used. These projecting pieces are made of soft rubber, foamed rubber, foamed plastic, or the like, and by attaching them to each tufted part, it is possible to perform pine surgery on both sides of the gums at once.

FIGS. 11 and 12 show a multifaceted toothpaste brush 1 that can simultaneously brush the front, rear, and occlusal surfaces of the upper and lower tooth rows. The first bristles 3 and the second bristles 7 of this multifaceted toothpaste brush 1 are wider than those of the multifaceted toothpaste brush 1 of the embodiment shown in FIG.
Two rows of long ovaries 13 are implanted in the longitudinal center of the cell, and their bent tips face in opposite directions, that is, outward. Furthermore, a plurality of rows of short ovaries 12 are planted on both sides of the long ovary 13, respectively.

As shown in the figure, the second flocked part 7 also has a similar configuration, and two rows of long ovaries 15 are also planted in the longitudinal center of the second flocked part 7, and their bent tips are mutually connected. facing in the opposite direction. Furthermore, a plurality of rows of short ovaries 14 are planted on both sides of the long ovary 15, respectively. By using such a multifaceted toothbrush 1, as shown in FIG. 12, it is possible to efficiently brush the front, rear, and interlocking surfaces of the upper and lower rows of teeth at the same time.

Branch portion 6 of the multifaceted toothpaste brush 1 shown in FIGS. 1 to 4
The teeth are sandwiched between the bristles 4 and 8 due to the elasticity of the material itself, but in the embodiment shown in FIGS. 13 and 14, the branch 6 is pivotally attached to the handle 2 and Apply clamping force.

That is, a slit 22 is formed near the tip side of the handle 2,
Insert the rear end 21 of the branch 6. The branch portion 6 is rotatably mounted on a pivot 23. A groove 24 is formed around the handle 2 behind the pivot 22, and also at the rearmost part of the rear end 21 of the branch 6! ! Form 25.

By fitting the annular rubber 26 into these grooves 24, 25, both the flocked parts 3 and 7 are biased toward each other. Note that biasing can also be achieved by attaching a tension spring instead of the annular rubber.

By configuring the toothpaste brush 1 like this,
The force of elastically pinching teeth between the bristles 4 and the bristles 8 can be strengthened. [Effects of the Invention] According to the multifaceted toothbrush of the present invention having the above configuration, the bristles of a pair of toothbrushes are connected to one side or the other. Since the tooth can be brought into contact with the front, rear and occlusal surfaces of the upper and lower tooth rows at the same time, teeth can be brushed quickly and effectively. Additionally, since the top and bottom of the bristles are open, the brush itself can be freely manipulated between the teeth.

Further, according to another embodiment of the present invention, the structure of the multi-faceted toothpaste brush can also be used for gingival musculosurgery, which is extremely useful in practice.
