Description

Toothbrush with one tuft

The present invention relates to a toothbrush with a one tuft.

In recent years, odor etiquette has been regarded as important, as there is the word “sumehara”. As a typical etiquette regarding such an odor, there is a countermeasure against bad breath. In the countermeasure against bad breath, tooth brushing is the most popular, but when brushing teeth, it is considered preferable to use a product such as a one-tuft brush in addition to a normal toothbrush. In recent years, as an example of such a one-tuft brush, the one disclosed in Patent Document 1 has been proposed.

A one-tufted toothbrush having a diameter and a height higher than the height of the bristle bundle.

This allows one brush to be efficiently brushed since the one tuft is integrated with the toothbrush. Further, since the one tuft is disposed at the center position of the brush portion, the load can be concentrated on the one tuft portion only by performing a normal brushing operation, so that the plaque can be efficiently removed.

Moreover, it is preferable that the diameter dimension of the one tuft is at least twice the diameter dimension of the hair bundle.

This can improve the plaque removal efficiency by one tuft.

Further, it is preferable that the brush portion is formed in a circular shape in plan view.

This makes it possible to brush the teeth without leaving any brushes and to concentrate the load on the one tuft regardless of the angle of entry (ingression state) into the mouth of the brush part. It can be done reliably.

In addition, it is preferable that the height dimension of the hair bundle gradually increases as it approaches the center position from the end side position of the flocking table.

This makes it possible to vary the bending state of each hair bundle, and it is possible to remove plaque according to each hair bundle and to efficiently perform normal brushing treatment.

According to the configuration of the toothbrush with a one-tuft according to the present invention, since the one-tuft is integrated with the toothbrush, it is not necessary to hold the toothbrush and the one-tuft brush for brushing, and the plaque removal process can be easily performed. It can be carried out.
In addition, since the one tuft is arranged at the center of the brush part, it is possible to concentrate the load on the one tuft only by performing a normal brushing operation. It is possible to remove plaque.
