Description

toothbrush

technical field

The present invention relates to toothbrushes.

Background technique

Dental lesions cause dental plaque to appear on the tooth surface as a result of food debris, etc., and streptococcus strains such as Streptococcus mutants, sugar components in plaque are The genus strains convert to acid, which dissolves the calcium component in the tooth. This is why brushing is advocated as a preventive measure against dental disease.

However, existing toothbrushes cannot inhibit the activity of bacteria and fungi as described above, although they are effective in removing plaque.

In connection with the above problems, the present inventors noticed that natural materials obtained from nature, especially products obtained by calcining and grinding natural porous materials rich in calcium components such as shells discarded as waste, have antibacterial and antifungal properties characteristics, and harmless to the human body.

Detailed ways

Hereinafter, the present invention will be described in detail with reference to examples of the present invention.

In the drawings, reference numeral 1 denotes a toothbrush comprising a plurality of bristles 3 inserted at the end of a handle 2 made of synthetic resin material. A bristle-forming synthetic resin material is used for the bristle 3 inserted at the end of the toothbrush 1, wherein a product obtained by grinding shells having a crystal structure of calcium carbonate calcite type structure is mixed with the synthetic resin material selected for the toothbrush bristle.

The handle 2 is made of a handle-forming synthetic resin material obtained by mixing a product obtained by grinding shells having a crystal structure of calcium carbonate calcite type structure with a synthetic resin material selected for the toothbrush handle of.

Shells mainly comprising at least one crystalline structure of calcium carbonate calcite type structure are used to obtain a product mixed into the handle 2 and the bristles 3 of the toothbrush 1 . This shell is a scallop shell, which is different from other shells because most of this shell has a crystalline structure. A scallop is characterized by its ecological state of moving rapidly to escape predators (such as starfish) when it appears to be "swimming in the sea" by opening and closing the shell so that sea water is forcefully expelled from the shell. Scallops have large shell ligaments for this movement, while the shell itself is fairly thin, lightweight and high strength. The crystal structure of the calcium carbonate-calcite type structure exhibits a leaf-like structure to form the inner surface of the shell, while the crystal structure of the calcium carbonate-calcite type structure exhibits a layered structure in the inner layer of the shell (the core layer in the thickness direction of the shell). Since the structure of the inner surface and the inner layer of the shell occupies the main part of the shell (parts other than the surface layer and the hinge), the shell is high in strength and thin and light in weight.

As described above, the crystal structure of the calcium carbonate calcite type structure exhibits a leaf-like structure (one in which needle-like crystals are tightly packed and arranged like kenzann (needle boards for arranging flowers)) on the inner surface of the main part of the scallop shell structure), while the crystal structure of the calcium carbonate calcite structure presents a layered structure in the inner layer of the shell (in which the needle-like crystals are arranged in the same direction to form a multi-layer structure like plywood, and the direction of the needle-like crystals is in each layer. between different multilayer structures). Therefore, the powder obtained by grinding scallop shells is porous and has a calcite-type structure, as described below. Unlike other types of shells, in which calcium carbonate crystals are stretched out and layered in planes, powders prepared from these shells are not porous, despite having a pearly luster.

When the scallop shell is used as a raw material of the product of the present invention as described above, the shell discarded as useless waste after removing the shell ligament can be utilized so that the waste is effectively utilized. First, discarded shells are collected and hardened by drying in the sun. Next, the shells, which have been hardened by drying in the sun, are ground into particles about 200 μm in diameter. The grinding method itself is not particularly limited, and existing grinders can be used. The calcium carbonate powder thus obtained comprises porous particles.

A part of calcium carbonate powder including porous particles is put into a rotary kiln and heated at about 1000°C for several minutes to several hours to obtain calcium oxide powder. The product of the invention is obtained by mixing calcium oxide powder with calcium carbonate powder.

This product is mixed with a synthetic resin material selected for bristles, the bristles3 being obtained by forming the resin into filaments. These bristles are inserted at predetermined positions on the handle 2 . Similarly, this product is mixed with a synthetic resin material selected for the handle, and the handle 2 is obtained by molding the resin material.

The calcium carbonate powder in the product includes porous particles characteristic of scallop shell powder as described above as a natural product. Since this product includes scallop shell powder as a natural product, it has antibacterial and antifungal properties common to this natural product. This antibacterial and antifungal property is used to inhibit the reproduction of bacteria and fungi. The product is exposed to the surface of the handle 2 and bristles 3 of the toothbrush, and by brushing the teeth with the toothbrush 1, bacterial and fungal activity is inhibited due to the antibacterial and antifungal activity properties shared by this product with natural products. "Natural product" here is a term opposite to "chemically synthesized product", and the shells of artificially cultured scallops are also natural products.

Calcium oxide powder is alkaline and has strong antibacterial and antifungal properties. When brushing teeth with the toothbrush of the present invention, the calcium oxide powder is converted into calcium hydroxide by the action of water in the oral cavity, and by forming an alkaline environment in the oral cavity, the reproduction of bacteria and fungi is inhibited, or bacteria and fungi are killed . Therefore, the toothbrush is very effective in preventing dental disease, and the hygienic condition of the toothbrush 1 is maintained after use.

Although the product of the present invention is a mixture of calcium carbonate powder comprising porous particles and calcium oxide powder prepared by calcining calcium carbonate powder, the product may be an aqueous solution of such a mixture, wherein the calcium carbonate powder has a calcium carbonate calcite type structure Shell powder with crystal structure. The product may comprise only calcium carbonate powder or calcium oxide powder, or an aqueous solution of calcium carbonate or calcium oxide. When this product is mixed as an aqueous solution with a synthetic resin material for the handle, and the handle 2 is molded from this material, a handle comprising a more dense distribution of antibacterial and antifungal substances on the surface can be formed. Similarly, when the product is mixed as an aqueous solution with a synthetic resin material for the bristles, and the bristles 3 are molded from this material, bristles comprising a more dense distribution of antibacterial and antifungal substances on the surface can be formed.

When the handle 2 and the bristles 3 are molded from the material in which the product of the present invention is mixed, either of the handle 2 and the bristles 3 may be molded from the material in which the product of the present invention is mixed.

Figures 2 and 3 show another embodiment of the invention. In this embodiment, the coating 5 is formed on the surface of the body 4 of the handle 2 of the toothbrush 1 as shown in FIG. 2, and the coating 5 is also formed on the body 6 of the bristles 3 of the toothbrush 1 as shown in FIG. on the surface. The coating 5 is formed by mixing the product as a powder or an aqueous solution with paint, and the mixture of product and paint is applied to the surface of the body 4 of the handle and the body 6 of the bristles.

Providing a coating 5 comprising this product on the surface of the handle 2 and bristles 3 allows the toothbrush 1 to exhibit beneficial effects such as obtaining antibacterial and antifungal properties.

The method for forming the coating is not limited to the coating method described above, and other methods such as spray paint and dip paint are also possible.

In this embodiment, the coating can be formed by mixing the product of the invention into the handle 2 or the bristles 3 . The materials used for the body 4 of the handle and the body 6 of the bristles are not limited.

Industrial applicability

According to the present invention, by using the toothbrush of the present invention to brush the teeth, an alkaline environment can be easily formed in the oral cavity, which can effectively prevent dental lesions by inhibiting the activities of bacteria and fungi in the oral cavity. The dissolved calcium component from the product of the present invention applied to the toothbrush may contribute to the growth of the teeth. The present invention also has the advantage of maintaining the hygienic condition of the toothbrush itself by enhancing the antibacterial and antifungal properties of the tooth itself.
