供し得ないものであつた。[Detailed description of the invention] The present invention is a toothbrush that can arbitrarily change the bending angle of the neck, which is formed between the flocked brush base and the handle, according to the user's preference. Among such brushes, there have conventionally been ones in which the neck formed between the flocked brush base and the handle is concave or bent in order to enhance the function of use. This is an attempt to effectively clean teeth with a toothbrush, but the size and shape of the mouth differs depending on the individual toothbrush user.
Standardization also had the disadvantage of making it difficult for users to use. In order to eliminate this drawback, there has been a neck made of propionate resin material that can be bent, but thighs made of this propionate resin material are
If you repeat the bending three times, it will break.
It was completely impossible to change the bending angle of the neck for each part to be polished. In addition to the above, there are other types of necks that can be bent.
No. 53-73169, Utility Model Publication No. 1983-106569, etc. exist, but in these, the neck is formed separately from a material different from the brush base and handle, and these separate members are connected and fixed. They were integrated together to form a single brush. This requires an extremely large amount of time and effort to manufacture, making it expensive, and the external design is not only undesirable as the connecting parts are exposed, but the neck part, which is supposed to be bent and deformed, is not designed to connect and fix separate parts. Since the connection and fixing part is formed by forming a joint, there is a strong possibility that the connection and fixing part will be damaged, and it could not be put to practical use at all.

To obtain a toothbrush with the best feeling of use by changing the bending angle, and to obtain a safe toothbrush that does not cause cracks or separation at the neck even when the bending angle is repeatedly adjusted. Therefore, by molding the neck formed between the brush base and handle integrally with the brush base and handle, not only will the damage described above not occur, but it will also be easier to manufacture and a cheaper product. In addition, since the connecting parts and the like do not appear on the neck, the aim is to obtain a product that has an excellent taste in terms of design.

を考案したものである。 An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a brush base, on the surface of which fibers such as nylon or boar hair are flocked to provide flocks 2, and a handle 3 is continuously formed. A neck portion 4 is formed between this handle portion 3 and the brush base 1 on which flocked hair is applied. The neck portion 4 is made of a nylon resin material that is bendable and can fix bending deformation within a certain range.The handle portion 3 and the brush base 1
The minimum part width a is formed in the range of 3 to 9 mm, and the minimum part thickness b is formed in a series so that the handle part 3 and the brush base 1 are narrower and thinner than the handle part 3 and the brush base 1.
is formed in the range of 2 to 6 mm. The inventor discovered that nylon resin materials such as nylon 12, nylon 6, nylon 66, nylon 610, and nylon 11 are materials that can be bent by human power and can maintain and fix this bending deformation state within a certain range. death,
As a result of various studies on the most desirable structure for using the properties of this nylon resin material in toothbrushes, we found that the neck 4 is the same as the handle 3, as described above.
And so that it is narrower and thinner than the brush base 1,
It was devised to form the minimum portion width a in the range of 3 to 9 mm, and to form the minimum portion thickness b in the range of 2 to 6 mm.

も、任意に何回でも行い得るものである。 By configuring as described above, if it is intended to hold the handle 3 and the brush base 1 and bend the neck 4 in any direction at any angle, the neck 4 will have a narrower width than the handle 3 and the brush base 1. Since the neck portion 4 is formed to be thin, the stress of bending is concentrated on the neck portion 4, and the neck portion 4 is bent at an appropriate angle. Moreover, even after the bending force is released, the toothbrush returns to its original shape a little, but due to the characteristics of the nylon resin, the bending angle is fixed within a certain range.
It is possible to adjust the bending angle to suit one's preference, and to change the bending angle as many times as desired.

However, this angle was maintained when using toothpaste. Also, after 24 hours, nylon 6 returns to 15 degrees and maintains this angle continuously, and nylon 66 returns to 15 degrees after 24 hours.
The angle was restored to 20 degrees, and this angle was maintained continuously thereafter.

るものである。 As described above, in the present invention, the neck formed between the flocked brush base and the handle is integrally molded with the brush body and the handle using a nylon resin material, and this neck is attached to the brush base. By forming the minimum part width in the range of 3 to 9 mm and the minimum part thickness in the range of 2 to 6 mm so that it is narrower and thinner than the handle part, the neck part can be bent and this bending deformation state can be maintained within a certain range. Since it is formed so that it can be held and fixed in any direction, if you want to hold the handle and the brush base and bend the neck in any direction and at any angle,
Since the neck is formed to be narrower and thinner than the handle and the brush base, the stress of bending is concentrated on the neck, causing the brush base and handle to be bent at an appropriate angle. The user can arbitrarily change the bending angle of the neck formed between the toothbrush and the toothbrush to suit the user's mouth, resulting in a toothbrush that is most comfortable to use.Since the toothbrush is made of nylon resin, it can be repeatedly Even if this bending angle is adjusted, there will be no cracking or separation of the neck, and it is possible to provide a safe toothbrush. By integrally molding the neck with the brush body and handle using nylon resin, the strength of the product is increased, manufacturing is easy, and a low-cost product can be obtained, and the connection parts do not appear on the neck. Therefore, it is possible to obtain something that has an excellent taste in terms of design.
