Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel toothbrush based on the philosophy of preventive dentistry.

Toothbrushes have long been used by people all over the world. When food particles accumulate between the teeth, it is unfavorable for oral hygiene, and it is common to experience that this can cause cavities, alveolar pyorrhea, and bad breath.

Therefore, although various improvements have been made to toothbrushes over the years, tooth and gum disease is not a cause that directly affects human life, so it is surprisingly easy to think about toothbrushes. Japanese people in particular are said to have stronger teeth than other foreigners, so this tendency is said to be stronger.

However, keeping teeth and gums strong is very important for human life, and changes in eating habits,
For example, as more and more soft foods are being provided that do not require much of the dental function, there is an increasing need to take measures to protect the teeth and gums from a preventive medicine perspective. That is the reality today.

Therefore, first, conventionally provided toothbrushes will be explained. The ones shown in Figures 1 and 2 are typical examples, but toothbrushes inherently suffer from problems such as (A) the overall structure of the toothbrush, and (B) the hardness (elasticity) of the handle. This toothbrush is characterized by having a curved surface.

Hereinafter, the present invention having such characteristics will be described in detail with reference to the accompanying drawings.

In FIG. 3 showing one embodiment of the present invention, the handle body (
1) is made of a material that has some degree of elasticity, such as acrylic plastic. This handle body (1
) Contact point (4) with the brush base (2) on the extension line of
constitutes a curved surface with an angle of about 30 degrees. This angle is by no means limited to a 30 degree angle,
A certain degree of range is of course allowed. In terms of use, it is preferable for this angle to be formed not at an acute angle but at a gentle curve to form an R-shaped curved surface. That is,
Specifically, the toothbrush can be smoothly inserted into the mouth cavity,
It does not damage the gums, provides a spring effect during use, and since the bristles of the brush do not spread out, it is extremely durable.

Next, the brush base (2) will be explained.

The brush base (2) and the flocked part (3) may be constructed in a slate shape, but as shown in FIG. If the tip of the flocked part (3) formed on the base (2) forms a Monson curve along the base (2), the teeth will not be constantly aligned. Since you can apply the toothbrush along the lines, the brushing effect increases. The bristles themselves may be planted in three rows in the longitudinal direction of the brush base (2), but may be in two rows. In short, if the flocking area is made too large as in the conventional technology, it will result in poor polishing.
It also results in damage to the gums, etc. Therefore,
Even for adults, the brushing effect will be better if the area of the flocked hair is made a little smaller. If the longitudinal tip (9) of the brush base (2) is configured with a curved surface, brushing can be performed more easily without damaging the inside of the mouth during use.

When brushing using the above-mentioned scrubbing method, the effect will be more pronounced if the following method is used to hold the handle of the toothbrush. The handle is held between the thumb, little finger, and other three fingers of the hand and polished. Depending on where you want to polish, turn the handle.
By changing the angle, you can brush all your teeth freely. In this case, it is effective to apply the brush to the teeth at an angle of about 45 degrees. If you hold the toothbrush in this way, you won't apply excessive force than necessary, so you won't damage your gums, and you'll be able to brush your teeth ideally when using the scrubbing method.

The present invention consists of the above-mentioned constituent elements, but the prior art (
Compared to the toothbrush according to Figures 1 and 2), the handle is made of an elastic material, the contact point with the brush base forms an R-shaped curved surface at an angle of about 30 degrees, and the brush base and bristles are Since the part itself can be constructed with a curved surface that matches the Monson curve, the following remarkable effects can be obtained.

According to the toothbrush according to the present invention, the handle of the toothbrush and the flocked hair,
In addition, the hand holding the handle interacts with each other in a well-balanced manner,
The brushing effect can also be obtained from an ergonomic point of view.

Specifically, the toothbrush has a curved surface at an angle of about 30 degrees near the contact point between the brush part that enters the mouth and the handle, which makes it extremely easy to brush, and the part where the brush part that enters the mouth is curved at an angle of about 30 degrees. never tired. This is because brushing can be done with the armpits closed. In addition, the brush can be applied parallel to the teeth and gums, providing an ideal brushing effect. As a result, you can avoid worrying about damaging your gums. In addition, with conventional toothbrushes, it is possible to completely brush the inside of the molars, which is considered difficult, and there is no residue left after brushing. Furthermore,
Conventionally, when brushing the inner side of the back, the handle touches the front teeth and makes it difficult to brush, but this problem does not occur when using the toothbrush according to the present invention.

In addition, in the present invention, the area of the flocked hair is made as small as possible, so it is easy to brush without damaging the gums.
The tip of the grafted hair can also be configured with a curved surface that conforms to the Monson curve, allowing the toothbrush to be applied to the teeth and gums in an ideal condition.

As described above, the present invention not only satisfactorily achieves the above-mentioned objects of the present invention, but also is an ideal toothbrush devised from ergonomic grounds.
