Abstract

PROBLEM TO BE SOLVED: To provide a toothbrush that facilitates brushing of the back of teeth.SOLUTION: A toothbrush has a bristle filling part in the vicinity of an end portion of a shank. A middle part of the shank is bent two times so that a front shank having the bristle filling part, a middle shank bent at a predetermined angle with respect to the front shank, and a rear shank bent at a predetermined angle with respect to the middle shank are integrally disposed together. Consequently, the front shank is located at a predetermined angle with respect to the rear shank to be held by a hand.

Description

  The present invention relates to a toothbrush having a bent handle.

  Conventionally, there are various types of toothbrushes. However, as shown in the present invention, a toothbrush having a handle with a handle bent twice is not found.

Toothbrushes are frequently used as tools for brushing teeth and keeping them clean. Generally, toothpaste is used by adhering toothpaste to the brush portion. There is a flocked part at the tip of the toothbrush handle, and toothpaste is placed on the flocked part, and the flocked part is lightly pressed against the front and back of the tooth and moved to brush the teeth. When brushing teeth, the surface of the teeth is easy to brush, but the problem is the backside.
Since human teeth are generally arc-shaped due to the shape of the oral cavity, a little ingenuity is required to polish the back of the teeth. Since the flocked portion of the toothbrush is rectangular in plan view, it becomes easier to polish the back of the tooth by holding the handle vertically.
However, for example, when brushing the back of the front teeth of the upper jaw, hold the handle of the toothbrush vertically, open the mouth, and press the flocked part against the back of the tooth to polish it. Part of the handle hits the lower lip, making it difficult to polish. In order to eliminate this difficulty, it is only necessary to change the angle of the handle so that the handle does not hit the lips. Can no longer be polished.
As described above, the conventional toothbrush has the problem as described above because the handle is substantially straight, but the present situation is that an appropriate solution for this has not been obtained.
In view of the above, the present invention has been invented in order to provide a new and useful means for solving the problems described above by making the handle a bent shape.

The present invention has the following configuration as means for solving the problems.
That is, in a toothbrush having a flocked portion in the vicinity of the end of the handle, the middle portion of the handle was bent twice, and the front handle having the flocked portion was bent at a predetermined angle with respect to the front handle. By integrally providing the middle handle and the rear handle bent at a predetermined angle with respect to the middle handle, the front handle is positioned at a predetermined angle with respect to the rear handle held in the hand.
The present invention is a bent pattern toothbrush having the above configuration.

  According to the present invention, since the handle is bent twice, it is provided to have a predetermined distance and a predetermined angle between the flocked portion and the rear handle of the toothbrush, so that the effect of facilitating the brushing of the back surface of the tooth is exhibited. Useful articles can be obtained. Moreover, it can be manufactured without being disadvantageous in terms of manufacturing cost by integrally forming the handle.

Hereinafter, embodiments of the present invention will be described.
In the figure, 1 is a handle, which is an elongated rod made of synthetic resin. Reference numeral 2 denotes a front handle, which is a flat plate portion having a predetermined length, and a flocked portion 3 made of a fibrous synthetic resin aggregate having an appropriate elasticity is planted on the upper surface thereof. Reference numeral 4 denotes a middle handle, which is a portion narrower than the front handle, and is a portion bent upward by 45 degrees with respect to the bottom of the front handle, and is a portion integrated with the front handle. .
5 is a rear handle, which is a slightly wider handle than the front handle, and is a portion that is integral with the middle handle and is bent at a predetermined angle with respect to the middle handle in a direction opposite to the above-described bending direction. It is.
The rear handle has an inclination angle of 20 degrees with respect to the front handle.
From the above configuration, the middle handle is bent 45 degrees upward with respect to the front handle, the rear handle is positioned at an angle of 20 degrees with respect to the front handle, and the handle having a shape formed by bending twice is formed. A toothbrush is formed.

Next, the use of the present invention will be described.
First, an appropriate amount of toothpaste is placed on the flocked portion, the rear handle is held vertically and held in the hand, and the handle is lightly pressed against the back of the tooth to raise and lower the handle. With this operation, the back of the tooth can be easily polished.
For example, when polishing the back of the front teeth of the upper jaw, the back handle has a distance and an angle with respect to the front handle surface, so that the handle touches the lower lip even when the flocked portion is aligned with the back of the tooth. It can be polished without any problems. In other words, in the example, the middle handle is bent at an angle of 45 degrees toward the flocked portion with respect to the front handle. Therefore, the middle handle protrudes obliquely outward from the opened mouth, and the rear handle is bent in the direction opposite to the folding direction of the middle handle, so that the rear handle angle in the hand is appropriate. .
In general, when brushing teeth, the elbow of the arm is first bent and the wrist is bent slightly, which is ergonomically natural.
It is necessary that the angle of the toothbrush handle used at this time is appropriate.
In the present invention, the reason why the first fold is set to 45 degrees is that it is suitable as an angle for bringing the middle handle that continues to the front handle from the mouth to the inside of the mouth. The second bend is set to 20 degrees with respect to the front handle in order to obtain an angle for holding the handle with a natural feeling, suitable for the above-mentioned continuous movement of elbow bending and wrist bending. is there. Therefore, in the present invention, the handle can be polished without touching the lower lip when brushing teeth while holding the handle with a natural feeling. At this time, the flocked portion can be polished at the same angle as the back of the tooth.
The above-mentioned angles are obtained as a result of the experiment, but there is no sense of resistance even when the first bending angle is in the range of 38 to 52 degrees and the second bending angle is in the range of 13 to 27 degrees. It is confirmed that it can be used.

Although the present invention has been described above, the present invention is characterized in that the handle is bent twice.
Since the conventional toothbrush handle is an unfolded single bar as shown in FIG. 3, for example, when the upper jaw front teeth are brushed, the handle does not hit the lower lip as shown in FIG. As a result, the flocked portion angle and the tooth back angle are inconsistent and it becomes difficult to polish sufficiently.
However, in the present invention, as shown in FIG. 4, since the handle is bent twice, it can be polished without touching the lower lip and the handle and with the tooth back angle and the flocked portion angle matched. is there.
In addition, it can be polished while maintaining the natural angle when holding the handle by folding twice.
The same is true when brushing the lower jaw front teeth, and the back tooth brushing is also effective.
The present invention was invented mainly for better polishing of the back of the tooth, but there is no problem in polishing the portion other than the back of the tooth. In addition, illustration is an example of implementation and it is good also as another structure of approximation. As described above, a toothbrush suitable for dentifrice brushing can be obtained according to the present invention.
