JPH09103325A - Tooth brush with diagonally cut bristle part - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable brushing of back teeth easily without causing a user to distort his mouth greatly sideways by arranging a diagonally cut bristle part of a tooth brush whose height is gradually lowered from the tip side to the rear side so that the grip of the tooth brush erects almost vertically to lips. SOLUTION: A diagonally cut trapezoidal bristle part 2 is so arranged on a planting base 1 of a tooth brush that the bristles longest on the first front row become evenly shorter backward one row by one row. When the outside of the back teeth is brushed, the brush can be smoothly inserted at an angle by little distorting a user's lips sideways. At the same time, even when the backward bristles touch the teeth, the longer front bristles can contact the teeth as well thereby achieving efficient brushing of the teeth.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothbrush which allows natural back teeth to be easily brushed.

[0002]

2. Description of the Related Art In a conventional toothbrush, a straight line drawn from the front portion to the rear portion of the bristle tip is parallel to a handle or a hair transplant base and a neck. Another type of prior art seeks to overcome the drawbacks caused by its nature by bending the neck of a toothbrush.

[0003]

[Problems to be solved by the invention]

I. To brush your back teeth with a conventional toothbrush, the handle must be close to vertical to your lips and your lips must be laterally distorted.
For that reason, there were times when I didn't know that and left my back teeth brushed, or didn't brush my teeth sufficiently. B. Further, the conventional type in which the neck of the toothbrush is bent has a drawback that it is difficult to use because it requires extra force and loses balance. C. Conventional toothbrushes have constant bristles or little difference. For this reason, the difference in how to bend and the change in pressure due to the difference in hair length is poor, and the efficiency of stripping plaque is not so good as it is rich in change. In addition, while the tips of the bristles that have high brushing ability are good, there are places where they do not come into contact with the curved or recessed parts of the teeth, causing tartar and astringency. The present invention has been made to solve the above drawbacks.

[0004]

Means for Solving the Problems A flocking part (2) is provided on a flocking table (1). The present invention is a toothbrush having a slope-type flocked portion having the above configuration.

[0005]

The function of the present invention is to insert the toothbrush of the present invention outside the posterior teeth. Then, at the angle of the pattern that hardly distorts the lips sideways,
Approximately the entire tip of the flocked part (2) contacts the tooth. Further, when the flocked portion (2) rubs the teeth, many kinds of bristles having slightly different lengths come into contact with each other. Hairs of different lengths have different ways of hitting, flexing and strength of teeth, which improves the ability to scrape plaque and other stains and efficiency.
No matter which part is brushed, the teeth have complicated and various height differences such as curved parts, recessed parts, and gaps. In the toothbrush of the present invention, the length of the bristles in the bristle-implanting part (2) is slightly different, so that the tip of the bristle having a high brushing ability of the bristle-implanting part (2) is in good contact with each other in a good condition.

[0006]

Embodiments of the present invention will be described below. Toothbrush flocking base (1) has a trapezoidal slope-shaped flocking part (2) in which the bristles in the frontmost row are the longest and the bristles gradually become shorter as they move backward one by one. To provide. The present invention has the above configuration. In the present invention, when brushing the outer side of the back teeth, the toothbrush may be inserted at a reasonable angle that does not distort the lips almost laterally. Then, since the hair-implanted portion (2) has the above-mentioned shape, the hair in the back portion prevents the hair in the front portion from trying to contact the back teeth even at an angle that does not distort the lips. There is nothing. Conversely, even when the back hairs are in contact with the teeth, they are also in contact with the teeth because of the long front hairs. Also, even if you brush like a conventional toothbrush, there are several types of bristles with slightly different lengths, so the difference in the length of the bristles affects the strength of hitting the tooth, how it hits, and how it flexes. ,
The ability and efficiency to remove dental plaque are increased. Moreover, the tip of the hair, which has a high brushing ability, is in good contact with the tooth just as well.

[0007]

The effects produced by using the present invention are as follows. I. You can comfortably brush your back teeth without standing the toothbrush vertically close to your lips and distorting your mouth to the side. B. The efficiency and efficiency of removing dental stains such as plaque have improved. It also reduces the time to brush your teeth. C. By improving the ability to remove dental stains such as plaque, you can brush with lighter force than before. Therefore, it does not hurt the gingiva more than the conventional toothbrush.
