Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an interdental brush used for removing food pieces, dental plaque, etc., which are clogged between teeth and gums adjacent to each other, and more particularly to the structure of a brush portion. Is.

[0002]

2. Description of the Related Art Conventionally, an interdental brush for cleaning an interdental tooth has been known. In recent years, in particular, there has been a growing interest in hygiene in the oral cavity.
Various types of interdental brushes have also been proposed for cleaning tooth spaces.

Such an interdental brush is generally composed of a grip portion to be held in a hand and a brush portion which is inserted between teeth to clean the portion. Of these, the brush portion is formed by implanting a suitable brush material such as nylon fiber in a spiral or radial fashion on a wire made of stainless steel or the like. Depending on the thickness and the length of the brush material, S size, M size,
There were only types such as L size.

On the other hand, the human oral cavity is various, and not only between the teeth adjacent to each other but also depending on the degree of gingival retraction,
The condition of the tooth gap is not generally classified. That is, when the gingiva is not retracted, the gap between the teeth is about 0.8 mm or less, and there is no room for inserting an interdental brush, but when the gingiva is retracted and the root is exposed or there is a missing tooth. , The tooth gap becomes about 1.7 mm or more.

In addition to the difference in the gap between the teeth of different people, the gap also differs depending on the part of the tooth, that is, the back teeth and the front teeth of one tooth. for that reason,
It was difficult to find the optimum interdental brush in the clearance of one's tooth with the above three types of interdental brushes. In this case, if the size of the brush portion does not match the clearance between the teeth, it may not be possible to perform sufficient cleaning during cleaning of the teeth or, conversely, the teeth and gums (gingiva) may be damaged.

Further, the stain between the teeth varies from a state in which food pieces are left alone to a state in which plaque is fixed. Therefore, originally, it is necessary to select an appropriate length, hardness and shape of the brush material according to the degree of contamination. On the other hand, the brush part of the conventional interdental brush is such that the brush material is flocked so as to have an even diameter and the same diameter over the entire effective length of the brush, or flocked in a wedge shape with a slightly longer root. It was Therefore, there is a limit in selecting an appropriate brush according to the contamination between teeth.

[0007]

SUMMARY OF THE INVENTION In view of the fact that the size of the tooth gap is different for each individual, the present invention makes it possible to select a wide range of interdental brushes that best fit the gap between the tooth gaps. The purpose is. Also, to provide an interdental brush capable of selecting the length, hardness, and shape of the brush material to most effectively clean the interdental tooth according to the purpose such as removal of food pieces and removal of dental plaque. The purpose is.

Means for Solving the Problems In order to solve the above problems, according to the present invention, in a brush portion of an interdental brush, the length of a brush material to be transplanted is lengthened stepwise from the tip of the brush toward the root, Alternatively, the thickness of the brush material is changed depending on the part of the brush, and the bristles density of the brush material is made higher depending on the part. Further, these configurations are appropriately combined.

[0009]

In the interdental brush of the present invention having the above-mentioned structure, the length, thickness, and flock density of the bristles of the brush material are varied depending on the part of the brush material. Has an effect that it can be applied to a portion having a narrow tooth gap and a long flocked portion can be applied to a portion having a wide tooth gap. Further, when changing the thickness or the flocking density of the brush material, for example, a thin brush material or a portion with a low flocking density is relatively soft, and therefore a thick brush material or a flocking density is not high when removing food pieces. Since the portion is highly elastic, it has the effect of being usable for removing plaque and the like.

[0010]

EXAMPLES Examples of the interdental brush according to the present invention will be described in detail below. FIG. 1 shows a brush portion 1 of an interdental brush in which brush materials 2 having different lengths are stepwisely applied (two steps in the figure) from a tip of the brush portion to a root portion, and wires 3 are implanted at equal intervals. Is. In this case, when the distance between the teeth is narrow, the bristle portion with a short tip is used, and when the tooth gap is wide, the bristle portion with a long root is used, so that the tooth gap can be cleaned without damaging the gingiva. Further, since the parts having the same length are provided with a predetermined width, the same effect can be obtained even if the parts are moved back and forth during cleaning.

FIG. 2 shows a brush material 2 in which the diameter is gradually increased (three steps in the figure) from the tip of the brush portion 1 to the root portion, and the wire 3 is planted at equal intervals. In this case, the tip portion is relatively soft due to the characteristics of the brush material, and the elasticity becomes stronger toward the root. Therefore, the use of a flocked portion having an appropriate hardness according to the condition of dirt between teeth such as food pieces and plaque can effectively clean the space between teeth.

In FIG. 3, the brush material 2 having the same thickness from the tip of the brush portion 1 to the root portion is planted on the wire 3 so that the bristle density is gradually increased. In this case, due to the flocking density, the sparse part feels soft and the dense part feels hard. Similar to the above, by cleaning the interdental space using an appropriate part according to the type of soil, effective interdental soiling Can be removed.

FIG. 4 shows an example in which the above embodiments are combined. In the drawing, the length of the bristles is changed stepwise and the thickness of the brush material is also changed. Indicates that the flocking length is changed and the flocking density is also changed. Further, shows an example in which the thickness of the brush material and the flocking density are changed at the same time. Further, the length of the brush material is changed stepwise, and the thickness and the flock density of the brush material are also changed. Such a combination of changes allows for the construction of an extremely wide variety of interdental brushes, allowing the consumer to select the most suitable interdental brush for their interdental gap.

Each of the above-mentioned embodiments conceptually shows the state of flocking. Therefore, in practice, for example, as shown in FIG. 5, the short-haired fibers of the brush material 2 are sandwiched between the wires 3 that are folded in half, and this constitutes a twisted spiral brush portion with the longitudinal direction as the axis. . Also,
Conventionally known techniques can be applied to manufacture the brush portion, such as radially implanting the brush material at appropriate intervals.

In the present invention, the material of the brush material to be used is not particularly limited, and in addition to the short hair fiber made of synthetic resin material such as nylon fiber which is generally used, a natural material can also be used. . Further, the length, thickness (diameter), flocking density, etc. of each brush material can be appropriately selected. Furthermore, in order to make the gradual change clear, for example, if different coloring is applied according to the length and thickness of the brush material, each function of the interdental brush can be easily identified and selected by the consumer, It is convenient to use.

[0016]

The interdental brush of the present invention having the above-mentioned structure is
When applying flocking to the brush part, the length, thickness, and flocking density of flocking are changed stepwise, or they are combined, so the size of the interdental space and the degree of dirt between the teeth are determined. Accordingly, a wide variety of interdental brushes can be provided. Therefore, the consumer can select the interdental brush that best fits the interdental gap, which is the most effective for cleaning the teeth without damaging the teeth and gums. Become.
