DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a toothbrush. More specifically, the present invention relates to a toothbrush suitable for brushing between teeth.

[0002]

2. Description of the Related Art For example, a toothbrush in which a bristle longer than other portions is implanted at the tip of an implanted portion, such as that described in Japanese Utility Model Publication No. 36-10649 and Japanese Utility Model Application Laid-open No. 58-14733, has been devised. Have been. Protruding the tip portion of the brush portion is considered to be convenient for brushing the back teeth. Further, it is described that the interdental recess can be efficiently brushed by using the above-mentioned tip.

[0003] Further, as disclosed in Japanese Patent Publication No. 62-260007, an arrangement is proposed in which an angle is formed between a handle and a brush portion so that brushing can be performed along teeth and the like. Have been.

[0004]

The toothbrush described in the above publication can be expected to have an effective brushing effect when there is no or little gap between teeth, that is, between teeth.

However, the tooth arrangement of the elderly often has a large gap between the teeth, and the conventional toothbrush cannot expect a sufficient brushing effect.

Further, in a brush having a long brush portion at the tip, when brushing is performed using a portion other than the above-mentioned tip portion, the brush bristles at the tip portion interfere with the teeth and hinder the brushing. Often. For this reason, not only the brushing efficiency is reduced, but also the handling is not easy.

In addition, since the tip is frequently bent in contact with the teeth, the tip is often deformed immediately. For this reason, there is a problem that the life is shorter than that of a general flat toothbrush.

The present invention solves the above-mentioned conventional problems and provides a toothbrush which can be expected to have a sufficient brushing effect even when the gap between teeth is large, is easy to handle, and has a long life. .

[0009]

Means for Solving the Problems To solve the above problems, the present invention takes the following technical means. The invention described in claim 1 of the present application is a toothbrush in which brush bristles are implanted in a base provided at a tip of a handle, and wherein the first base is so arranged that the tips of the brush bristles are substantially along one plane. A first brush portion implanted and formed on the second brush portion, and a second brush portion implanted and formed on a second base portion such that a tip end of the brush bristles follows a triangular chevron. The second brush portion and the second brush portion are separated from each other so that when one brush portion is used, the other brush portion does not interfere with the teeth.

That is, the present invention provides a structure of a normal flat toothbrush in which the tips of brush bristles are formed along a plane,
A triangular mountain-shaped second brush portion suitable for brushing between teeth is provided independently of the first brush portion.

Since the first brush portion is formed so that the tip of the brush bristles is along a plane, the side surfaces and the meshing surfaces of the teeth can be brushed efficiently. On the other hand, since the second brush portion is formed in a triangular mountain shape, it is possible to efficiently brush the interdental recess.

Further, in the present invention, the first brush portion and the second brush portion are provided so as to be separated from each other so that when one brush portion is used, the other brush portion does not interfere with the teeth. I have. For this reason, by selectively using each brush part, the function of each brush part can be sufficiently exhibited, and a high cleaning effect can be expected.

Also, when there is a large gap between the teeth,
Since the second brush portion can be used independently, brushing can be sufficiently performed.

Further, when one of the first brush portion and the second brush portion is used, the other brush portion does not interfere with the teeth, so that there is no sense of incompatibility in use. The part does not deform in a short time.

The triangular chevron shape of the second brush portion only needs to be formed in a triangular chevron shape at least in a side view of the toothbrush, and can be formed in the same shape in the width direction of the handle. Moreover, it can also be formed in a triangular pyramid shape.

In the invention described in claim 2 of the present application, the second platform is formed integrally with the tip of the first platform.

By providing the first base portion and the second base portion adjacent to each other, the two brush portions can be selectively used only by changing the angle at which the handle is gripped. Therefore, there is no need to change the toothbrush when using these brush parts properly. Also in this case, the first brush part formed on the first base part and the second brush part formed on the second base part are arranged in a state of being separated from each other. When the brush part is used, the other brush part does not interfere with the teeth. Therefore, the brush part that is not used does not hinder brushing and does not come off quickly.

As means for avoiding interference between the brush bristles and the teeth, it is conceivable to provide a region where no bristles are provided between the first brush portion and the second brush portion. Since the outer shape of the second brush portion according to the present invention is formed in a triangular mountain shape, a sufficient effect can be expected if the above-mentioned region is opened by one pitch of the brush implantation pitch.

Further, as in the invention described in claim 3,
The second pedestal is integrally extended from the tip of the first pedestal at an angle of 10 to 40 degrees in a direction in which the bristles of the second brush are separated from the bristles of the first brush. Can be formed.

By forming the first base and the second base at an angle, the angular interval between the first brush and the second brush is increased, and the gap between the brushes is reduced. Substantially spread. For this reason, when one brush part is used, the other brush part can further reduce interference with the teeth. The angle can be changed within the above range in accordance with the triangular chevron shape of the second brush portion, the purpose of use, and the like. For example, when brushing by yourself, the angle is in the range of 10 to 30 degrees. It is preferable to set.
On the other hand, in the case of a toothbrush or the like for an infant that is assumed to be polished by an adult, the angle can be set in the range of 20 to 40 degrees.

According to a fourth aspect of the present invention, the first brush is formed at one end of the handle, while the second brush is formed at the other end of the handle.

By providing the first brush portion and the second brush portion separately at both ends of the handle, it is possible to prevent the other brush portion from interfering with the teeth when using one brush portion. Absent.

It is preferable that the first brush portion and / or the second brush portion are formed at an angle with respect to the axis of the handle. As described above, this angle is 10 degrees to 4 degrees.
It is preferable to set the angle in the range of 0 degrees.

According to the invention described in claim 5 of the present application, the first base and the second base are formed at one end of the handle, and a third base is formed at the other end of the handle. The third base is provided with a third brush portion in which the tips of the brush bristles follow a triangular mountain shape. That is, in the present invention,
Triangular chevron shaped brush parts are provided at two places.

The arrangement of teeth and the shape of the teeth vary greatly depending on the user. Therefore, it is not always possible to sufficiently brush all the teeth with one shape. Also, front teeth,
In some cases, it is better to make the extension angle of the base different depending on the position of the teeth such as the back teeth.

[0026] For example, as in the invention described in claim 6 of the present application, the third pedestal is moved by 10 degrees in a direction in which the bristles of the third brush part approach the bristles of the first brush part. It can be formed integrally with the handle at an angle of up to 40 degrees.

When the above-mentioned angle is employed, it is possible to easily brush the interdental portion outside the dentition by the second brush portion, while easily brushing the inside of the dentition by the third brush portion. it can.

According to a seventh aspect of the present invention, a flocked surface bent in a substantially V-shape is formed on the second and / or third pedestal, and the inner angle of the substantially V-shape is formed. The brush bristles planted on one of a pair of bristled surfaces opposed to each other and the bristles planted on the other cross each other, and the tips of these bristles form a substantially triangular mountain shape. It is.

Normally, as the angle at which the brush bristles abut on the tooth surface deviates from a right angle, the tip of the brush bristles deviates from the tooth surface, and the brushing effect is reduced. In particular, when brushing the interdental recess, even if the tip of the brush portion having the brush bristles planted in the same direction is cut into a triangular mountain shape,
The brush bristles lie on the tooth surface, and a sufficient brushing effect cannot be expected.

In the present invention, a pair of flocked surfaces are formed so as to face each other with a substantially V-shaped inner angle therebetween, and the brush bristles are crossed according to the V-shaped angle. Is cut so that the tip of forms a triangular chevron.

By adopting the above configuration, the brush bristles can be brought into contact with the tooth surface of the interdental portion at a large angle close to a right angle. Moreover, since the contour is formed in a triangular mountain shape, the brush bristles near the triangular apex can penetrate deep into the teeth. Therefore, the brushing effect is dramatically improved.

According to the invention described in claim 8 of the present application, it is possible to bend one or more portions of the brush stand and / or handle on which the bristle is planted, and to maintain the angle at a desired angle. It can be used in.

Conventionally, a toothbrush having a handle or base at a predetermined angle has been provided. However, the optimum angle differs depending on the arrangement of teeth, age, and the like.

The present invention is configured so that the user can set the handle or the base to the most appropriate bending angle by himself. The bending mode may be configured so that the entire toothbrush can be continuously curved, or may be configured to be bent at a predetermined position.

Further, it is necessary to add a shape retaining function so as to withstand the force acting during brushing after bending. As a means for maintaining the shape, it is conceivable to form the outside with a deformable resin material, such as a free curve ruler, and to embed a plastically deformable and shape-retaining material such as lead into the core.

According to the invention described in claim 9 of the present application, a material capable of plastically deforming and retaining a shape is embedded in a handle and / or a base formed of a deformable resin material.
A notch concave portion is formed in a portion to be bent, where the handle is bent in a predetermined direction.

As a material capable of deforming the composition and having a shape maintaining ability, a metal material such as lead is used. The above-mentioned material can be formed in a line shape or a bar shape and embedded along the axis of the handle. The portion to be embedded may be embedded over the entire length of the handle, or may be embedded in a portion to be bent.

When the notch recess is provided, it is possible to bend the portion intensively. In particular, by forming the notch recesses on both sides of the outer periphery of the handle, the handle can be easily bent at that portion.

The part to be bent is not particularly limited, but it is preferable that the first, second, and third pedestals can be freely bent.

The invention described in claim 10 of the present application is substantially equivalent to V
A bristle planted on one of a pair of flocked surfaces facing each other across an inner angle of the substantially V-shape, and a bristle planted on the other side, forming a base portion having a flocked surface bent in a letter shape, While crossing each other, the tips of these brush bristles form a triangular mountain shape.

The invention described in claim 11 of the present application is substantially equivalent to V
