Abstract

(57) [Abstract] It is an object of the present invention to provide a toothbrush having a brush structure in which the hardness of the bristles of a toothbrush is freely set and arranged appropriately in a brush portion. [Structure] The stiffness of the brush bristles according to the application can be freely determined based on the length of the brush bristle from the base material surface to the tip of the brush bristles by providing the base portion of the toothbrush having the roots with irregularities. The configuration was adopted.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a toothbrush for irritating the mouth, and in particular, irrigating and gingival.

[0002]

[Prior art]

 The hardness of the bristles of the brush portion of the conventional toothbrush is controlled by the length of the bristles, the diameter of the bristles, or the material of the bristles, and the toothbrush is configured. In particular, the length of the brush bristle has a planar structure in the base of the brush on which the toothbrush is planted, and the length from the base of the brush to the tip of the bristle is uniform throughout the brush. The brush part and the toothbrush are composed of a uniform length and uniform bristle hardness.

[0003]

[Problems to be solved by the invention]

 The hardness of the bristles of the conventional toothbrush is determined by the length of the bristles, the diameter of the bristles, or the material of the bristles, so that the bristles of the toothbrush are uniformly stiff and soft. It is common practice for the user to select and use one of the stiffnesses in between. However, in practice, since the hardness of the bristles of the brush part is uniform throughout, the user contacts the teeth or gums through the handle of the toothbrush base material by hand or arm as necessary. In general, the intensity of the brush pressure is adjusted. For this reason, it has been difficult to properly use places requiring strong brushing or places requiring soft brushing. Further, it was more difficult to selectively clean and stimulate a small region in the mouth between the back teeth / teeth and the gingiva to obtain an effect.

[0004] Furthermore, due to the configuration in which the length of the bristles of the toothbrush is implanted at a constant length, in use, the bristles provided especially on the outer periphery of the brush portion are likely to bend and bend and deform in many cases. There was a problem that the durability of the brush portion was poor.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, the hardness of the brush bristles according to the use is provided, and the base portion of the toothbrush on which the bristles are implanted is provided with an uneven shape, and the brush bristles are formed from the base portion surface. The configuration was determined from the length of the brush bristle to the tip.

[0006] The hardness of the bristles of the toothbrush depends on the length of the bristles due to the elastic properties of the bristles when the diameter and the material of the brush portion are the same. Therefore, when the brush bristles are relatively long, the deformation under a certain pressurization is large, and the bristle of the brush portion is soft, and conversely, when the brush bristles are relatively short, the deformation under a constant pressurization is small. The hair becomes firmer. Therefore, the brush bristles are soft in the former configuration and strongly contact the teeth or gingiva in the latter configuration. In the present invention, the toothbrush arranged in the brush portion was provided with the hardness of the bristle according to the intended use, based on the uneven shape of the base portion of the toothbrush on which the hair was implanted.

[0007]

[Embodiment of the invention]

 An embodiment of the invention will be described based on an example with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of the present invention. The toothbrush shown in FIG. 1 has a convex shape at the tip of the base portion where the brush portion is planted. The length of the bristles is short at the tip of the brush portion, and the bristles close to the handle of the brush portion are relatively long. Brush hairs were placed on the For this reason, in this toothbrush, the brush portion has a bristle brush tip, and the brush portion close to the handle of the toothbrush has a brush portion in which soft brush bristles are arranged. When the toothbrush shown in FIG. 1 is used centering on the tip of the brush portion, it is possible to brush more strongly and to a small area of the teeth or gingiva.

The uneven shape of the base portion of the toothbrush on which the hair is implanted is not only in the longitudinal direction of the brush portion shown in FIG. 1, but also in the base portion in the direction perpendicular to the longitudinal direction and an arbitrary portion of the entire base portion. It is possible to do so. Further, it is also possible to form an appropriate brush portion by selectively adding the brush hair hardness, the brush diameter, and the material together with the brush bristle length.

[0009]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 2 is a sectional view showing an embodiment of the present invention. The base portion in the direction perpendicular to the longitudinal direction of the brush portion of the toothbrush was shown, and a gentle concave portion was provided in the center of the base portion. Therefore, on the toothbrush base material shown in FIG. 2, short bristle is arranged at both ends of the base material portion, and relatively long bristle is arranged at the center of the base material portion. Therefore, on both sides in the longitudinal direction of the planted brush portion, the brush portion is configured such that the bristle is firm and the center portion is soft. By using this toothbrush to brush the teeth in the vertical direction, it is possible to apply strong cleaning and irritation to the teeth or gingiva, and to remove the brush bristle provided on the outer periphery of the brush. The hardness prevents the brush from being deformed and improves the durability of the toothbrush.

[0010]

【The invention's effect】

 In the present invention, the brush bristles of the toothbrush can be determined by the structure of the base material where the bristles are planted. Thus, it is possible to obtain a toothbrush capable of improving the cleaning effect on the teeth or the gingival part, effectively stimulating, and cleaning and stimulating a required specific area.

[0011] Further, it is possible to configure a brush portion that can withstand long-term use, and to improve toothbrush durability.
