JPH04112628U - A toothbrush with bristles with an oval cross section - Google Patents

Abstract

(57) [Summary] [Purpose] To ensure that the flocked hair enters even the narrow gaps between the teeth, removes dirt from every corner, and prevents the flocked hair from falling. [Structure] Each of the bristles 1, 1... formed in an oval shape with a cross section having a major axis D is oriented perpendicularly to the center line Y in the longitudinal direction of the toothbrush handle 2. The flocked hairs 1, 1, . . . are planted on the base 3 in the same direction.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a toothbrush.

0002

[Conventional technology]

Conventional hair transplantation involves curling the tips of each hair one by one to avoid damaging the teeth, or In this method, the grafted hair is tilted from the periphery to the center of the inside to form a pyramid-shaped graft to remove tartar. There are some that focus on prevention.

0003

[Problem that the idea aims to solve]

Both conventional hair transplants with rounded tips and pyramid-shaped hair transplants are effective. The cross section of the hair is all circular, so it is difficult to get into the narrow spaces between teeth, and The problem was that it was easy to fall over. This invention allows the flocked hair to enter even the narrow gaps between teeth, removing dirt from every corner. The aim is to provide a toothbrush that can prevent the hair from falling down. .

0004

[Means to solve the problem]

In order to achieve the above purpose, in the toothbrush of the present invention, the cross section of the flocked hairs is oval. The long diameter side of the oval cross section of the flocked hair is formed into a circle and the cross section is oval. It is planted in the width direction perpendicular to the handle.

[0005]

[Effect]

Hold the toothbrush handle horizontally, place the bristles between your teeth, and brush up and down. The thin, pointed outer peripheral surface on the long diameter side of the cross section penetrates deep into the narrow gap between the teeth. In addition, since the cross section is formed in an oval shape with the major axis in the width direction, It can prevent it from falling outward in the width direction.

[0006]

【Example】

In Figures 1 to 3, 1, 1... has an elliptical cross section consisting of a major axis D and a minor axis d. This is the hair transplant that was formed. 3 is the base of the toothbrush on which each flock 1 is implanted, and the handle of the toothbrush is The width direction of the toothbrush perpendicular to the longitudinal center line Y of 2 (as shown in Figures 1 and 3). The hair transplant 1 is placed on the base 3 with the major axis D of the hair transplant 1 aligned in the direction (X direction). to be planted. In addition, for flocking 1, it is not necessary to make all the flocks of the toothbrush oval in cross section. Instead, it is desirable to mix it with conventional hair transplants that have a circular cross section.

[0007]

[Effect of the idea]

Since the present invention is configured as explained above, the following be effective. When you move your toothbrush up and down along the gaps between your teeth, the long axis of the oval cross section becomes tapered. The side tip penetrates deep into the narrow gaps between the teeth and removes dirt from every corner. This prevents the flock from falling in any direction, allowing excellent brushing power to be maintained over a long period of time.
