Abstract

PROBLEM TO BE SOLVED: To regularly bring only the bristle end part into contact with teeth by setting the height of planted lines of bristle bundles to a laterally symmetrical and uniform step form having a specified number of steps when seen from the front. SOLUTION: Bundles 1 of bristles are planted so as to have a laterally symmetrical and uniform step form, when seen from the front, to form a toothbrush. The lines of bristle bundles differed in height in four stages at the minimum are arranged on both lateral sides. When the step planted toothbrush is used, the side surface of a tooth 4 can be cleaned with the bristle end part simultaneously with the clearance between the tooth 4 and the gum 5. When the surface or reverse side of teeth is cleaned by rolling method, also, it is eliminated that the bristle end part of the brush can not touch the teeth by the rolling of the bristle. The whole stepped bristle end on one side of the toothbrush regularly surely makes contact with the teeth, whereby a high cleaning effect can be provided.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention efficiently and simultaneously cleans the gap between teeth and gums and the side surfaces of teeth when brushing teeth by the bath method. Also, the present invention relates to a toothbrush that enhances the cleaning effect by constantly contacting only the bristle tip with the tooth surface when brushing teeth by the rolling method.

[0002]

2. Description of the Related Art Conventional toothbrushes have a dome-shaped part of a bristle part or a mountain-shaped part of a bristle part.
As the brush as a whole, bristles having substantially the same length are implanted. For this reason, if you brush between the teeth and gums with the bath method,
Some groups of brush bristles will bend, making it very unlikely that the most cleansing bristles will touch the teeth. And the group of bent bristles are not brushing their teeth, they are simply stroking the sides of the teeth. Furthermore, when brushing the teeth by the rolling method, the time during which the bristles having the best cleaning effect were in contact with the teeth was very short due to the same reason, and the cleaning efficiency was low.

[0003]

The cleaning efficiency can be improved by making it possible to clean the gap between the teeth and the gums and the side surfaces of the teeth at the same time, and to always keep only the hair tips in contact with the teeth. Try to let it.

[0004]

Means for Solving the Problems When viewed from the front of the toothbrush, the brush bristles are arranged such that the height of the rows of the bristles of the bristles of the bristles is symmetrical and has a uniform step shape of four or more steps. Means of planting the rows of bundles.

[0005]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, when the toothbrush is viewed from directly in front, a brush is formed by implanting the bristles 1 in a uniform stepwise manner in a symmetrical left and right state. At this time, rows of brush bristles having different heights are arranged in at least four steps on the left and right. FIG. 2 is a side view of the entire step-like flocking toothbrush. When the step-like flocking toothbrush of the present invention is used as shown in FIG. 3, it is possible to clean the side surfaces of the teeth 4 at the same time as the gap between the teeth 4 and the gums 5 at the bristle tips.

Also, when brushing the tooth surface and the back side of the tooth by the rolling method, the brush bristles are not bent so that the tip of the brush does not hit the teeth, and the stairs on one side of the toothbrush are always maintained. When the entire bristle tip of the brush is in firm contact with the teeth, a higher cleaning effect can be obtained than with a conventional toothbrush.

【The invention's effect】

As described above, the present invention always realizes a state in which only the bristle part is brushing teeth. For comparison, as a result of experimentally using the conventional toothbrush and the present invention with the same cleaning method and the same cleaning time, a higher cleaning efficiency was obtained with the toothbrush of the present invention than with the conventional toothbrush. Was.
