Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems in a conventional toothbrush that bristles are difficult to fit between teeth and easy to fall at the root because the bristles are made of nylon or the like which is easy to fall and collectively bundled to prevent the falling; a brush head has laterally restorable force but no vertical elasticity and is difficult to remove dirt because it is in contact with a hard material such as acrylic resin or polypropylene in the part of a handle; and the nylon resin damages or injures the gum with a less massage effect because it is a material harder than the gum. <P>SOLUTION: The lower part of the brush head part at the tip of the handle is surrounded by silicone rubber or the like, whereby the number of bristles can be minimized, and minute clearances between teeth can be easily polished by use of the vertical and lateral elasticity of the silicone rubber or the like. The gum can be directly massaged by the silicone rubber or the like. The gum can be simultaneously massaged with polishing the teeth. A material generating minus ions is put in the silicone rubber, whereby the blood circulation is promoted to enhance the massage effect. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothbrush, and more particularly to cleaning teeth and tooth stains, periodontal pockets and the like, and gum massage.

(Prior Art) In a conventional toothbrush, the material of the brush is made of thin nylon, bristles, etc., and it is easy to fall from the root. Also, in order to prevent it from falling over, many are bundled together, so it is difficult to enter the gaps between the teeth.

Further, the brush itself is not made of silicone rubber or the like which is softer than the gum.

(Problems to be Solved by the Invention) A conventional toothbrush is made of thin nylon or the like and has a bristle property. Therefore, each toothbrush easily falls, and in order to make it hard Because it is made, the gap between the bundles is also made narrow, so it is difficult to enter into the fine gap between the teeth. Also, it will fall down at the root.

Further, since the brush is in direct contact with a hard material such as acrylic resin or polypropylene of the handle portion, it has a force to return to the left and right, but it does not have the elasticity of the upper and lower sides, so it is difficult to remove dirt and is difficult to polish. Further, since nylon resin is a material harder than gingiva, it has little massage effect by damaging or damaging the gingiva.

(Means for Solving) The purpose of brushing teeth is to
It is of course necessary to clean the surface of the teeth, but to prevent periodontal disease and periodontitis, it is desirable to remove the dirt from the teeth where food residue easily accumulates between the teeth and the periodontal pocket.

Further, massage of gingiva is also important. This is because various causes can be considered for periodontal diseases and diseases related to teeth such as gingivitis. When the resistance of the whole body such as a cold is weak, the gums immediately swell, or when smoking tobacco, the action of nicotine tar causes the blood vessels to contract and the blood flow to deteriorate, and the white blood cells that fight bacteria Function is diminished, and purulence and inflammation are more likely to occur in diabetes. Also, people with weak immunity are more likely to suffer periodontal disease.

Although rare, periodontal disease occurs due to pregnancy, and periodontitis caused by gingivitis and stress during adolescence.

Further, in order to maintain a long life of the tooth, there is a problem that the tooth will come off unless the gum supporting the tooth is normally strong.

Therefore, in order to solve the above problems, the present invention mounts silicone rubber or the like on the upper end of the handle,
By attaching several nylon brushes to the silicone rubber, it becomes easier to polish by utilizing the elasticity of the silicone rubber. Also, since it is silicone rubber, it does not permanently bend from the root.

Further, since the silicone rubber is present around the brushes, the number of brushes to be bundled can be reduced, so that the brushes can easily enter between the teeth. In addition, the gum can be massaged without using a brush and using only silicone rubber or the like. Also, by incorporating a substance that generates negative ions such as tourmaline into silicone rubber, etc., it improves the performance and enhances the massage effect. In addition, the gingiva can be massaged at the same time as the fine gap between the teeth is polished.

(Embodiment of the Invention) According to the invention of claim 1, various silicone rubbers are attached to the upper part of the tip of the handle of the toothbrush, and a thin nylon resin brush is attached to the silicone rubber.
Attach it so that it is about 5 mm to 5 mm. The shape of silicone rubber is cylindrical, cone-shaped, box-shaped, and several thinly processed cylindrical shapes are formed on it to form a protruding shape. Conceivable.

According to the second aspect of the present invention, silicone rubber is attached to the tip of the handle portion. The silicone rubber can have various shapes. It has a cylindrical shape with a diameter of 1 to 3 mm,
You can attach several pieces with a height of about 3 mm to 1.5 cm, or make several box-shaped pieces that are thinly processed into a cylinder or the like so that they are protruding, or use silicone rubber. Various shapes are conceivable, such as making a notch or attaching silicone rubber to the outside of a normal toothbrush in a horseshoe shape. or,
There are various types of silicone rubber such as adult teeth, child teeth, sick teeth, and various tooth types, so various shapes can be considered to enhance the massage effect.

According to the third aspect of the present invention, the massage effect is enhanced by adding a tourmaline rough stone or the like that generates negative ions to the silicone rubber, or by mixing a powder of tourmaline with the silicone rubber or the like. .
