Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention makes it easy to visually check the extent of damage to the brush, allowing you to accurately determine when it is time to replace it. It relates to a toothbrush that can be gripped.

0002

[Conventional technology]

The filament that makes up the brush part of a toothbrush is designed to prevent elasticity from decreasing due to water absorption. Nylon filaments with low water absorption are used for this purpose. Such a toothbrush If the tips of the bristles become bent due to daily use, the cleaning and massage functions will be reduced. It is preferable to replace it with a new one.

0003

[Problem that the idea aims to solve]

However, the nylon filament brush part gradually The ends of the hair will become bent, so if you use this every day, the ends of the hair will become erect. It is difficult to recognize the extent of damage compared to the original state. again There is a tendency for users to continue using even damaged toothbrushes, and It is difficult to properly replace toothbrushes that are due for replacement. And hair A toothbrush with a sharply curved tip not only does not have a sufficient cleaning function for teeth and between the teeth, but also Since it causes damage to the gums, there is a risk that the user's dental health may be adversely affected.

0004 By the way, the applicant previously installed a large number of cylindrical single materials made of synthetic resin material on the brush stand. (Utility Model Application No. 61-207232 and Utility Model Application No. No. 61-207233). However, all of these toothbrushes are made of single material with elasticity. Therefore, the purpose of these products is to massage the gums, and they have little tooth cleaning function. The reality was that there was little to hope for.

[0005] This invention makes it easy to visually check the bending of the filament tip as it is used. The user can accurately recognize when it is time to replace it, and the cleaning function and massage function are also available. The purpose is to provide a toothbrush that has both

[0006]

[Means to solve the problem]

In order to achieve the above purpose, the present invention consists of a large number of filaments on the brush stand. In addition to arranging hair bundles at regular intervals, in place of the above hair bundles, these hair bundles are placed in one or more places. A method of erecting a cylindrical body made of a highly hydrophobic polymeric elastic material with the same height as that of the was used.

[0007]

[Effect]

In the present invention based on the above-mentioned technical means, hair bundles made of filaments cannot be used. The tips of the hair gradually bend as a result, but the shape of the circle made of highly hydrophobic polymeric elastic material The column does not lose its elasticity even if it gets wet from toothpaste, so the toothbrush remains upright when first used. maintain. Therefore, the cylindrical body is made of nylon filament with bent and lowered bristles. The filament protrudes from the tip of the filament, and the degree of damage to the hair bundle made of the filament. can be checked at a glance. Also, when brushing your teeth, the nylon filament bristles touch your teeth. While cleaning between the gums, the cylindrical body made of elastic polymer material massages the gums. play an action.

【Example】

Hereinafter, the configuration of the present invention will be described in more detail according to the embodiment shown in the drawings. , In Fig. 2, 1 is the handle of the toothbrush, 2 is the brush stand, and 3 is the four rows on the brush stand 2. The brush part is arranged in rows, and the hair bundles 4 are drawn from the nylon filament at regular intervals. At the same time, the first and last rows of the inner two rows are replaced with hair bundles 4, and hydrophobic polymer It is made up of cylindrical bodies 5 of the same height that are made of silicone rubber as an elastic material. Ru.

[0009] In the toothbrush of the above embodiment, the bristles 4 are formed in the brush portion 3 as the toothbrush is used. The tip of the nylon filament will gradually bend, but the inner circle of the brush The column 5 does not absorb moisture and maintains its elasticity, so it maintains its upright state when first used. When the user looks at the brush section 3 from the side, he/she will see that the brush section 3 is bent as shown in FIG. The tip of the inner cylindrical body 5 in an upright state appears to protrude behind the hair bundle 4. By comparing these two, visually observe the degree of bending of the hair bundle 4 and check the degree of damage. It is something to check.

0010 FIG. 4 shows another embodiment of the brush section according to the present invention, and the brush section has a three-row configuration. Regarding No. 23, the entire inner row is made of cylindrical body 5, and both sides are made of nylon filler. The hair bundle 4 is made of hair. In this embodiment, the hair bundle 4 is compared with the cylindrical body 5. Visually checking the degree of damage due to use is the same as in the above example, but the inner row is completely inspected. Since all of the teeth are made of cylindrical body 5, the massage function for brushing teeth is further enhanced.

[0011] In addition, in the present invention, a cylindrical body 5 is used instead of the nylon filament hair bundle 4. The standing position is not limited to those in each of the above embodiments, and may be set as appropriate according to the specifications of the toothbrush, etc. In addition, in order to make the comparison between the cylindrical body 5 and the hair bundle 4 clearer, the circular The silicone rubber constituting the column 5 may be appropriately colored. Furthermore, the above cylinder If the body 5 is made of a highly hydrophobic polymeric elastic material other than silicone rubber, this is particularly limited. It's not something you do.

0012

[Effect of the idea]

The toothbrush of this invention has bristles made of filaments lined up at regular intervals on the brush stand. At the same time, in place of the above-mentioned hair bundle, there is a hydrophobic layer of the same height as the above-mentioned hair bundle in one or more places. It consists of a cylindrical body made of a highly elastic polymeric material. Therefore, the user As you brush your teeth every day, the tips of the filaments that make up each hair bundle gradually become bent. Even if the You can easily and reliably grasp the degree of damage to the hair strands by comparing it with the toothbrush. Appropriate exchange of brushes becomes possible. Also, a toothbrush with severely damaged bristles will not stand upright. The difference from the cylindrical body becomes even more obvious, and it gives the user a kind of warning. Continued use of a damaged toothbrush can be effectively prevented.

[0013] Furthermore, when using the toothbrush of the present invention, the bristles made of filaments At the same time, the cylindrical body can clean the teeth and between the teeth effectively. Due to the surge, teeth It has various excellent practical benefits, such as the improved health of people. Ru.
