Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothbrush in which a brush portion of the toothbrush is bendable with respect to a grip portion.

[0002]

2. Description of the Related Art As a conventional toothbrush, there have been proposed a number of toothbrushes each having a brush portion in which bristles are planted and a grip portion which can be held by hand.

[0003]

In the conventional toothbrush, generally, the brush portion is formed in a straight line through the constricted portion at the tip of the grip portion. For this reason, when brushing the teeth, it is not possible to clean the inside or inside of the teeth beautifully, but the stains on the teeth cause plaque.

This plaque needs to be removed because it causes bad breath and alveolar leakage, but it is extremely difficult to remove this plaque with a normal toothbrush.

For this reason, conventionally, a large force is applied to the toothbrush for rolling, but this causes an excessive force to be applied to the brush and damages the brush, resulting in a significantly long usable period of the toothbrush. It becomes short and uneconomical.

That is, when brushing teeth using this toothbrush, generally, the direction in which the teeth such as the front part of the dentition and the back teeth are aligned with the direction in which the toothbrush is planted is used to roll the hair. When applying a large force to the toothbrush and rolling, the hair begins to bend or open in a short period of time.

When the hair is bent or opened in this way, it becomes more difficult to remove the plaque between the interdental part and between the teeth and gums, the food waste, and the plaque, so that the teeth can be polished more beautifully. As a result, it cannot prevent tooth decay and alveolar pyorrhea.

[0008] That is, when dirt, food waste, and dental plaque remain between the teeth and between the teeth and gums, bacteria are propagated by using these as nutritional sources, which may cause bad breath and p of saliva.
H is made small, that is, it is made acidic and influences promotion of tooth decay and alveolar pyorrhea.

For this reason, there is a need to use a new toothbrush when it is bent or opened when it is opened, but most of the materials used for the toothbrush are produced by the large consumption of fossil resources. The destruction of the global environment due to the large consumption of this fossil resource is of great concern. For this reason, it is necessary to pay attention as much as possible to such a large consumption of fossil resources to prevent the wasteful consumption of the resources as much as possible, but the toothbrush so far has not considered this point at all. is there.

Furthermore, if a toothbrush is applied with a large force to roll while brushing the teeth, a large force is applied to the brush portion as described above to damage the gums. From this point as well, it is not possible to roll with a strong force. It is not desirable.

According to the present invention, in the toothbrush, the brush portion is formed so as to be bendable with respect to the grip portion so that the brush portion can surely contact the dirty portion of the tooth. As a result of reliably removing dirt,
An object of the present invention is to provide a toothbrush from which the cause of dental plaque is removed by allowing the teeth to be beautifully brushed.

[0012]

In order to achieve the above object, the toothbrush of the present invention comprises a brush portion in which bristles are planted and a grip portion, and the brush portion is formed to be bendable with respect to the grip portion. It is characterized by being.

In the toothbrush of the present invention, the brush portion formed by implanting bristles and the grip portion may be integrally formed, or may be formed separately, and the brush portion is attached to and detached from the tip portion of the grip portion. It may be formed so that it can be attached freely.

As described above, in the toothbrush, if the brush portion is detachably attachable to the tip of the grip portion, when the bristles of the brush portion open and become unusable, only the brush portion becomes bristled. Accordingly, the gripping portion can be used for a long period of time to minimize waste of resources as much as possible.

The toothbrush of the present invention is most characterized in that the brush portion is formed so as to be bendable with respect to the grip portion. Therefore, as a material for forming the brush portion and the grip portion, The same one as the conventional one is used.

In the toothbrush of the present invention, the structure in which the brush portion is formed so as to be bendable with respect to the gripping portion is not particularly limited. For example, a strip-shaped body or a rod-shaped body made of steel is used. The toothbrush described below is desirable because it can be inserted from the tip to the brush, but the angle described below can be adjusted and adjusted with respect to the grip.

That is, a gap guide portion communicating from the grip portion to the brush portion is provided, and a long spring member having a bent front end portion is provided slidably in a stretched state in the gap guide portion. Is preferably provided with an operating portion for sliding the spring member.

As described above, in the toothbrush of the present invention, the gap guide portion communicating from the grip portion to the brush portion is provided,
A long spring member having a bent front end portion is slidably provided in the gap guide portion in a stretched state.

Therefore, when the spring member is slid toward the brush portion and moved forward, and the bent portion of the spring member comes close to the tip of the grip portion, the bent spring member has a gap in the expanded state. Since the brush portion is provided in the guide portion, the restoring force of the spring member naturally causes the brush portion to bend gradually, and the angle of the brush portion can be arbitrarily adjusted by advancing and retracting the spring member.

In this case, when the adjusting member for advancing the spring member is provided at the rear end of the grip portion, the advancing amount of the spring member can be adjusted by operating the adjusting member, so that the bending angle of the brush portion can be adjusted. It is extremely useful because it can be controlled more strictly.

Further, if the gap guide portion at the tip of the grip portion is configured to gradually widen toward the tip, the spread of the gap guide causes the bending angle of the brush portion to be delicate over a large range. It is extremely useful because it can be controlled.

By the way, this spring member is not limited in shape, and any one can be used, but a strip-shaped or rod-shaped one is particularly preferable because it is easy to operate, and this spring member is the operating portion. The tip is bent so as to naturally bend by operating.

Although the material of the spring member is not particularly limited, it is desirable that the spring member is made of a corrosion resistant metal from the viewpoint of durability and safety.

Further, in the present invention, it is advantageous that the bristles of the brush portion are coated with a resin layer containing a bactericide, for the reason described below.

That is, when brushing the teeth with a toothbrush,
In particular, tooth stains adhere to the bristles or get entangled, but it is difficult to remove the tooth stains attached to the brush even after washing, especially when the brush entangles. Is more difficult to remove.

For this reason, bacteria are propagated in the dirt, food waste, etc. remaining on the brush portion, resulting in extremely unsanitary conditions. By coating the hair with a resin layer containing a bactericide in this manner, Such a problem does not occur.

In this case, the bactericide may be mixed with a synthetic resin, a solvent or a dispersant, and the mixed solution may be dipped in hair to be dried, or the mixed solution may be sprayed onto the hair and dried.

The bactericide used in the present invention is not particularly limited as long as it has high safety, for example, it can be used for food additives.
Examples thereof include benzoic acid, sorbic acid, dehydroacetic acid and the like.

The blending ratio of the bactericide and the synthetic resin varies depending on the sterilizer and the synthetic resin used, but generally it is in the range of 0.01 to 10 parts by weight per 100 parts by weight of the synthetic resin. If the compounding ratio is less than 0.01, the desired effect may not be obtained in some cases, while if it exceeds 10 parts by weight, it is not desirable because it is uneconomical as well as meaningless.

[0030]

The toothbrush of the present invention has the above-mentioned structure, and is composed of a brush portion in which bristles are planted and a grip portion to be gripped by a hand, and the brush portion is formed to be bendable with respect to the grip portion. Thus, when the toothbrush is used, the angle of the brush portion can be changed so that the brush portion comes into contact with the portion of the tooth to be brushed, so that the tooth can be brushed beautifully.

That is, when brushing teeth using this toothbrush, generally, the direction in which the teeth such as the front part of the dentition and the back teeth are aligned with the direction in which the toothbrush is planted is used to roll the hair. As described above, it is possible to easily remove plaque and food waste between the interdental part and between the teeth and gums, and to make the teeth beautiful so that plaque is hard to occur and it has the effect of preventing tooth decay and alveolar pyorrhea. .

Further, since the spring member indicates the brush portion, if an excessive force is applied to the toothbrush, the brush portion is bent and the gum is not applied with excessive force, and as a result, the gum is not damaged. It has an action.

Further, since no excessive force is applied to the brush portion of the toothbrush in this manner, the hair does not open or bend during rolling, and the toothbrush can be used for a long period of time. To have.

In the present invention, when the bristles are coated with a resin layer containing a bactericidal agent, when brushing teeth with this toothbrush, tooth stains adhere to the brush part, especially between the bristles, or Although it sickens, the disinfectant has an extremely hygienic effect because it suppresses the residual dust on the brush and the growth of bacteria in the dregs as much as possible.
