Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a toothbrush.

[0002]

Conventionally, as a cause of tooth decay, streptococci called mutans bacteria are interposed on the tooth surface, and food residues and the like are stopped as plaques. As a result, sugars in the plaque are converted to acids by lactic acid bacteria, lactic acid bacteria, and Candida bacteria, and the acid dissolves the calcium content of the teeth. For this reason, toothpaste is encouraged as a preventive of tooth decay. However, the conventional toothbrush used for brushing is intended to remove the plaque and has a certain effect, but does not suppress the activity of the fungus.

[0003] In response to the above-mentioned problems, the present inventors have developed a product obtained by calcining and pulverizing natural materials obtained from the natural world, particularly natural calcium-rich materials such as shells which have been disposed of as waste. However, they are not harmful to the human body but have an antibacterial property. In view of the above circumstances, an object of the present invention is to provide the product on toothbrush bristles to suppress the activity of fungi in the mouth and to prevent tooth decay.

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above problems, and is made of a synthetic resin containing a product obtained by pulverizing a shell having a crystal structure having a calcite-type structure of calcium carbonate. An object of the present invention is to provide a toothbrush characterized by having a bristle made of a material, and to solve the above-mentioned problems. In the present invention, the product is a shell powder having a crystal structure having a calcite-type structure of calcium carbonate, a calcium carbonate powder comprising porous granules, and a calcium oxide obtained by calcining the calcium carbonate powder. It is preferably a mixture with a powder or an aqueous solution of the mixture.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail based on embodiments. That is, in the toothbrush of the present invention, the bristles of the brush are made of synthetic resin bristles into which a product obtained by crushing a shell having a crystal structure having a calcite-type structure of calcium carbonate is mixed. The hair is planted at a desired position on the brush handle.

In order to obtain a product to be mixed with the bristles of the toothbrush, first, a shell is used in which at least a main part of the shell has a crystalline structure of a calcium carbonate calcite structure. This shell is a scallop shell, and the scallop shell differs from other shells in that most of the shell has this crystal structure. In other words, scallop in its ecology, open and close the shell, release the seawater vigorously to the outside, move quickly as described as "swimming in the sea", and escape from the captor (starfish etc.) It is characteristic, has a large scallop so that this operation can be performed, and has a condition that the shell itself is relatively thin and lightweight and has strength. In the shell, the calcite-type crystal structure of calcium carbonate has a leaf-like structure, forming the inner surface of the shell, and the inner layer of the shell (the core layer in the shell thickness direction) has a calcite-type crystal of calcium carbonate. The structure has a plate-like structure, and the structure between the inner surface of the shell and the inner layer of the shell forms the main part of the shell (excluding the surface layer and hinges). There is something. As described above, in the main part of the shell of the scallop, the crystal structure of the calcite-type structure of calcium carbonate has a leaf-like structure on the inner surface side (a state in which needle-like crystals are densely packed in a sword mountain shape and laid out. ), And the inner layer of the shell has a plate-like structure of a calcite-type crystal structure of calcium carbonate (layers of needle-like crystals arranged in the same direction, such as plywood, overlap in layers, and the orientation of the needle-like crystals Is different for each layer), so that the granules obtained by crushing the scallop shell have a calcite-type structure and are porous as described later. On the other hand, other shells have a structure in which calcium carbonate crystals are spread in a plane and overlapped, giving a pearly luster. It does not exhibit sex.

[0007] As described above, scallop shells are used as a raw material in obtaining the product, but those that have been treated as unnecessary after removing the scallop can be used, and useful waste can be used. . First, the unused shells are collected, dried in the sun, dried and hardened. Next, the shells cured by drying in the sun
Grind to 0 μm. The crushing method itself is not particularly limited, and an existing crushing device may be used. Thus, calcium carbonate powder is obtained, and the granules are porous granules. Next, using a part of the calcium carbonate powder composed of the porous granules described above, the calcium carbonate powder is placed in a ceramic pot and heated at a temperature of about 1000 ° C. for several tens of minutes to several hours to remove the calcium oxide powder. To get. A product is obtained by mixing the calcium oxide powder and the calcium carbonate powder. Then, the product is mixed with the resin to form a filament to obtain the hair of the toothbrush, which may be implanted at a desired position of the brush handle.

[0008] In the above product, the calcium carbonate powder is composed of unique porous granules of scallop shell powder which is a natural product as described above. As described above, the product is made of scallop shell powder, which is a natural product, and has an antibacterial property of natural products in general. In this toothbrush, the product is exposed on the surface of the hair. Therefore, if the toothbrush is brushed with this toothbrush, the activity of fungi is suppressed by the antibacterial action of natural products in general. Here, the natural product is a counter electrode of the chemically synthesized product, and the cultured scallop shell is also a category of the natural product.

The calcium oxide powder is alkaline and has high antibacterial properties. If the toothbrush is brushed with the toothbrush of the present invention, the calcium oxide powder is changed to calcium hydroxide by intermingling with moisture in the mouth, and an alkaline environment is formed in the mouth to kill fungi and to reproduce the bacteria. Deterrent, and thus has a tremendous effect on the prevention of dental caries.

In the above-described embodiment, the product is a shell powder having a crystal structure of calcium carbonate having a calcite-type structure, a porous granular calcium carbonate powder and a calcium oxide powder obtained by calcining the calcium carbonate powder. , But may be an aqueous solution of this mixture. Also,
The product may be, for example, the calcium carbonate powder alone or the calcium oxide powder alone, or a water-soluble product thereof.

[0011]

According to the toothbrush of the present invention described above, there is provided a synthetic resin bristles into which a product obtained by crushing a shell having a crystal structure having a calcite-type structure of calcium carbonate is mixed. By brushing the teeth with this toothbrush, an alkaline environment can be easily formed in the mouth, and the activity of fungi in the mouth can be suppressed, which is effective in preventing tooth decay. In addition, the calcium content from the hair can contribute to the formation of teeth, and the effect of the present invention is excellent in practicality.
