Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothbrush for brushing teeth, and is particularly suitable for cleaning the oral cavity.

[0002]

2. Description of the Related Art The mouth for taking in food, which is indispensable for sustaining life, is in an environment where it constantly becomes dirty as an entrance organ of the esophagus and as a respiratory organ or vocal organ. In addition, the mouth, that is, the oral cavity is always soiled due to the phenomenon of saliva discharge, discharge of carbon dioxide gas or sputum from the trachea, and the occasional backflow of food in the esophagus. Even if no special measures are taken by the natural discharge of carbon dioxide and sputum from the mouth, and by the saliva containing a bactericidal substance that kills other fungi as well as digestive enzymes for digesting food. The oral cleanliness is maintained to some extent. However, it is difficult to keep the inside of the oral cavity sufficiently clean only by such natural movements, and it is necessary to brush the teeth with a toothbrush or gargle with water or chemicals. Is kept clean.

However, even if the above-mentioned measures are taken, it is impossible to give a perfect measure for preventive hygiene.
Occurrence of stomatitis or tonsillitis is observed due to the occurrence of tooth decay, alveolar pyorrhea, or deterioration of physical strength. Even if you do not get sick, it can cause bad breath, which can cause considerable mental distress for some people. Traditionally, halitosis has been thought to occur especially because of alveolar pyorrhea and poor gastrointestinal conditions, but recently, tongue coating (read as "zei"), mainly white moss that forms on the tongue, and Old sputum collected at the base of the tongue has also been considered to be the cause of bad breath. This inner tongue coating is well understood because it accumulates white on the surface of the tongue, but old sputum accumulated at the base of the tongue (hereinafter referred to as "tongue sputum") is not noticeable until it increases to some extent.

By the way, the name "tongue moss" is a commonly used term, and the medical name is moss tongue (coated tongue).
gue)). And medically, the "moss tongue" is a tongue with a white layer on the upper surface of the tongue, which is the epithelial debris,
It is composed of food particles and bacteria and is often a sign of indigestion and high fever. ”These tongue coatings and sputum are more common in younger people than in younger people, and during medical treatment. This is a phenomenon that is particularly common in the elderly and has been known for a long time, but recently in Japan, allergies to bad breath in young people are extremely strong and cause bad breath. Young people are becoming particularly interested in the visible tongue coating.

By the way, as an instrument for removing tongue coating and tongue sputum, there has been a name such as a tongue shaving device or a tongue shaving device from old times, and there is a theory that it was used instead of brushing teeth in old times. In other words, in the old days there was a time when prioritizing the removal of tongue coating and tongue sputum with a tongue scraper or tongue cover scraper was more important than brushing teeth. It's hard to think of returning to the old habits in today's era of much longer life expectancy and sweets, but it's a rethink of youth etiquette. .

By the way, the tongue scraper or tongue cover scraper for removing tongue coating and tongue sputum has been sold finely from the old days to the present day without being generally known. Some are now marketed under the name "tongue cleaner" or "phlegm cleaner".

[0007]

However, the number of shops selling the products is limited, and since the products are not publicized at all, it is inconvenient for the general public to know where they are sold. . In addition, when multiple people in the family use torso scrapers or tongue cover scrapers, one tongue scraper or tongue cover scraper has hygiene problems, so you should purchase many of the same thing. This means putting them side by side on the washbasin, which is unattractive and wasteful.

Further, all of the torso scrapers or tongue cover scrapers currently on the market are specially designed for removing tongue cover, and have an inconvenient shape for removing tongue and sputum. In view of such a point, the present invention is easy to obtain in the market,
It is another object of the present invention to provide a toothbrush that effectively removes tongue coating and tongue sputum in the oral cavity, especially tongue sputum, even if there are any number of them in a family.

Further, the neck portion 4 is formed with a slight curve toward the brush 1 side in order to facilitate brushing of the teeth.

At the end of the handle 2 opposite to the head 3,
A tongue coating scraping portion (shaving portion) 6 is provided. The tongue coating scraping part 6 is for removing tongue coating in the oral cavity and tongue sputum accumulated in the back of the throat, and has a shape of a lotus-like or spoon-like depression as shown in FIGS. 1 and 2. The edge portion 7 is formed so that it is thinner toward the tip and the cross section of the tip is round so as not to damage the tongue and mucous membrane in the oral cavity. That is, if the edge portion 7 is too obtuse, the tongue coating and tongue sputum cannot be properly removed, and if it is too acute, there is a risk of damaging the tongue and mucous membrane in the oral cavity.
Is formed at an angle θ (hereinafter referred to as a “gentle angle”) at which the tongue coating and tongue sputum can be easily removed, and the tip has a certain degree of roundness. The above gentle angle is about 30-
The angle in the range of 90 ° is used as a guide, and this range may be exceeded if necessary.

Although the edge portion 7 is formed in a substantially symmetrical shape to the left and right, it is not necessary to form the entire edge of the tongue coating scraping portion 6 into an edge shape. Further, the edge portion 7 to the bottom portion of the spoon-shaped tongue coating shaving portion 6 is formed smoothly with an appropriate depth, but there is no special limitation on the depth, and even if the depth is shallow, there is almost no depth. Good. Further, a through hole 8 having a predetermined shape and size is provided at a substantially central portion of the tongue coating scraping portion 6.
