Abstract

To develop a toothbrush capable of removing plaque adhered to a tooth, tobacco dust, etc. in a short time. Toothbrush bristles are those in which a large number of abrasive particles are mixed and a part of the abrasive particles are exposed on the surface of the bristles, or a large number of abrasive particles are adhered to the surface. . Since teeth are directly brushed with bristles having abrasives, it is possible to clean plaque and spear neatly in a short time without using a dentifrice containing harmful chemical components. [Selection] Figure 1

Description

  The present invention relates to a toothbrush used for brushing teeth and cleaning the oral cavity.

In the conventional toothbrush, for example, as shown in FIGS. 1 and 2, a large number of hairs are divided into a plurality of hair bundles at the tip of an elongated handle and are implanted. One hair bundle consists of 10 to several tens of hairs, and the thickness of the hair is about 0.1 to 0.35 mm in diameter. The material of the hair is a natural material such as horse hair or pig hair, or a polymer material such as nylon, acetyl resin or polyester.
Toothbrushing is usually performed by applying a toothpaste to the brush portion of the toothbrush.
Dentifrices include agents such as surfactants, abrasives, and bactericides.

The abrasive contained in the dentifrice is ultrafine particles, and the particle size may be several μm or even 1 μm or less, and since it is an ultrafine particle, the polishing effect is small, and it removes plaque adhered to teeth and tobacco dust. Takes time.
Some chemicals (such as sodium lauryl sulfate) contained in dentifrices are said to be harmful, and there is a risk of developing diseases such as stomatitis.

This invention makes it a subject to develop the toothbrush which can remove the plaque adhering to a tooth | gear, the tobacco dust, etc. in a short time.
Another object of the present invention is to develop a toothbrush that can remove plaque, tobacco dust, etc. without using a dangerous toothpaste.

[Claim 1]
The present invention provides a toothbrush in which a large number of bristles are planted at the tip of a handle, and all or some of the bristles are mixed with a large number of abrasive particles, and a part of the abrasive particles are part of the bristles. The toothbrush is characterized by being exposed on the surface of the toothbrush.

[Claim 2]
Further, the present invention is characterized in that in a toothbrush in which a large number of bristles are planted at the tip of the handle, all or a part of the bristles have a large number of abrasive particles attached to the surface. Toothbrush to do.

[Claim 3]
Moreover, this invention is a toothbrush of Claim 1 or 2 whose Mohs hardness of the said abrasive | polishing agent is 5-10.

[Claim 4]
Moreover, this invention is a toothbrush in any one of Claims 1-3 whose said toothbrush is an electric toothbrush.

Since the toothbrush of the present invention directly brushes teeth with bristles having an abrasive, it can cleanly remove plaque and stains in a short time without using a dentifrice containing a harmful chemical component.
Moreover, even if such a dentifrice is used, since toothpaste can be completed in a short time, the damage received by a chemical substance can be reduced.

FIG. 3 is a plan view of a main part of the toothbrush B. FIG. 3 is a plan view of a main part of the toothbrush C. FIG.

FIG. 1 is a cross-sectional view of a bristle 1 used in the toothbrush of the present invention.
A large number of abrasive particles 3 are mixed in the hair 1, and a part of the abrasive particles 3 is exposed on the surface of the hair 1.
The material of the hair 1 can be a polymer material similar to the hair of a conventional toothbrush, such as nylon, acetyl resin, or polyester.
The thickness of the bristle 1 is preferably 0.1 to 0.35 mm in diameter, similar to a conventional toothbrush.

As abrasives, particles such as garnet, amethyst, aquamarine, diamond, emerald, moonstone, ruby, peridot, sapphire, opal, topaz, turquoise, ceramics and silica can be used.
The Mohs hardness of the abrasive is suitably 5-10.
The particle size of the abrasive particles is preferably 10 to 100 μm, and preferably 1/3 or less of the diameter of the hair.
The amount of abrasive particles is suitably about 1 to 10% by volume.

In order to manufacture the hair 1, abrasive particles are mixed and dispersed in a base material such as nylon, acetyl resin, or polyester.
Additives such as a diluent, a dispersant, and a coupling agent are added as necessary so that the abrasive particles are suspended in the base material liquid.
As the dispersant, stearic acid-based dispersants (magnesium stearate and the like), silicone oils and the like can be used.
As the coupling agent, for example, a silane coupling agent such as chloropropylsilane can be used.
By extruding the base material prepared in this way, hair 1 mixed with a large number of abrasive particles 3 as shown in FIG. 1 can be obtained.

FIG. 2 is a sectional view of the bristles 2 used in the toothbrush of the present invention.
The bristles 2 are obtained by attaching a large number of abrasive particles 3 to the surface of the bristles via an adhesive.
The body of the bristles 2 may be those used in conventional toothbrushes, and natural materials such as horse hair and pig hair, and polymer materials such as nylon, acetyl resin, and polyester can be used.

  As the abrasive particles, the same particles as in the case of the hair 1 can be used.

In order to produce the bristles 2, an adhesive in which abrasive particles are dispersed in a suspended state may be coated around the bristles. The coating method is arbitrary such as dipping.
As the adhesive, an acrylic adhesive, an α-olefin adhesive, a urethane resin adhesive, an epoxy resin adhesive, or the like can be used. Abrasive particles are mixed into these adhesives, and additives such as diluents, dispersants, and coupling agents are added as necessary to prepare a coating liquid.

FIG. 3 is a side view of an essential part of the toothbrush A of the embodiment, and FIG. 4 is a plan view of the essential part.
The toothbrush A is a manual toothbrush, and a large number of hairs are divided into a plurality of hair bundles 6 and planted at the tip of the elongated handle 5.
The bristles used for the toothbrush A are the bristles 1 of FIG. 1 and / or the bristles 2 of FIG. 2 having abrasive particles.

FIG. 5 is a plan view of an essential part of the electric toothbrush B (vibration type) of the embodiment.
The electric toothbrush B also has a plurality of hairs divided into a plurality of hair bundles 6 at the tip of the elongated handle 5 and is planted. The proximal end side of the handle 5 is connected to a main body having a vibration mechanism.
This type of toothbrush vibrates in the sliding direction indicated by arrow X and / or vibrates in the direction around the axis indicated by arrow Y.
The bristles used for the toothbrush B are also the bristles 1 of FIG. 1 and / or the bristles 2 of FIG. 2 having abrasive particles.

FIG. 6 is a plan view of an essential part of the electric toothbrush C (rotary type) according to the embodiment.
In the electric toothbrush C, a large number of hairs are divided into a plurality of hair bundles 6 on the rotary disk 7 at the tip of the elongated handle 5 and are implanted. The proximal end side of the handle 5 is connected to a main body having a rotation mechanism.
In this type of toothbrush, the rotating disk 7 rotates as indicated by an arrow Z.
The bristles used for the toothbrush C are also the bristles 1 of FIG. 1 and / or the bristles 2 of FIG. 2 having abrasive particles.

  The handle and flocking method used for the toothbrush of the present invention may be exactly the same as a conventional toothbrush.

All the planted hair may have abrasive particles (FIGS. 1 and 2), or some (for example, 50%) of the hair may have abrasive particles, and the rest may have no abrasive particles. Ordinary hair may be used.
By adjusting the proportion of hair having abrasive particles, the degree to which the teeth are polished can be adjusted.

  The toothbrush of the present invention can be added to the aesthetic taste by lineup of products using precious stone abrasives of various colors such as birthstones and matching the color of the pattern to the color of the abrasive. In addition, the user can be identified by the color of the abrasive.

  Since the toothbrush of the present invention brushes teeth directly with bristles with abrasives, it can cleanly remove plaque and stains in a short time, but it cannot be denied that the teeth are damaged. However, the combined use of a dentifrice containing apatite, calcium ions, fluorine, etc. can reduce the risk of damaging teeth.
