Description

Detailed Description of the Invention

[Field of Use on Sanitary Goods] The present invention relates to a toothbrush with a step at the tip of the tooth for autopsy, which is produced by implanting a bundle of bristles having different lengths on a handle of a toothbrush. It is about.

[Prior Art] In a conventional toothbrush, there are various tooth-contact portions of the bristles, such as a flat surface, a mountain shape, a spherical shape.

[Problems to be Solved by the Invention] This has the following disadvantages. (A) In both cases, the length of the bristles is uniform, so the tooth contact surface of the toothbrush is flat, so the tooth contact area of the toothbrush is narrow, and the pressure on the tooth surface of the bristles is equal, so It was hard to get used to the subtle unevenness of the tooth surface. (B) For this reason, there was a large amount of unpolished space between the teeth and tooth surfaces, and it was difficult to remove plaque. (C) It took time and effort to clean the tooth spaces and tooth surfaces cleanly. The present invention has been made to eliminate these disadvantages.

[Means for Solving the Problem] A toothbrush handle (1) is bristled with a bundle (2) having a combination of bristles having different lengths, and a step is formed on each tooth-contacting portion of the bristle tip. (3) is provided.
The present invention is a toothbrush having a step at the bristle tips of the tooth-contacting portion having the above-described structure.

[Operation] A conventional toothpaste is used to brush the teeth at the tooth-contacting portion having the step (3). The tip of the hair with the step (3) easily adapts to the fine irregularities between the tooth surface and the tooth,
Easy to remove plaque.

[Embodiment] An embodiment of the present invention will be described below. (A) A bunch (2), which is a combination of bristles having different lengths, is planted on the handle (1) of the toothbrush, and a step (3) is formed at the tooth-contacting portion of the bristle tip. (B) Using a conventional toothpaste, brush at the tooth-contacting part of the tip with the step (3). As a method of forming the step (3), the hair tips may be cut after the hair is transplanted. Further, the number of steps and the number of steps may be increased or decreased depending on the purpose of use of the product.
