Problems solved by technology

[0016] However, the invention of Patent Document 1 has such a problem: when the toothbrush bristles are planted on the planted surface, they are easily cracked and damaged by mechanical impact.
In particular, when the toothbrush bristles are transplanted with a general wire-type hair transplanting device, when the toothbrush bristles are supplied to the hair transplanting machine, or when the toothbrush bristles are nailed into the hair-planting surface, there is a problem that the toothbrush bristles are easily split.
The inventions of Patent Documents 2 to 3 have the problems of complicated manufacturing process and high cost
The invention of Patent Document 4 has the problem that it is difficult to control the length and thickness of the branch portion

no. 1 approach

[0053] Next, the toothbrush bristles according to the first embodiment of the present invention will be described with reference to the accompanying drawings. figure 1 It is a front view which shows the state which the bristles of the toothbrush according to this embodiment are implanted on the implanted surface.

[0054] Such as figure 1 As shown, the toothbrush bristle 1 has: a main body 10 and three branch parts 20 extending on the main body 10 .

[0055] The main body portion 10 is a columnar portion extending from the base end 11 to the tip end 21 in a state where the toothbrush bristles 1 are implanted on the hair-implantation surface 40 .

[0056] The columnar shape refers to a circular cross-sectional columnar shape with a cross-sectional shape perpendicular to the lengthwise direction of the bristles, and includes substantially cylindrical shapes. The shape of the main body portion 10 may be substantially cylindrical, and is preferably cylindrical.

[0057] The base ...

no. 2 approach

[0095] The toothbrush bristles according to the second embodiment of the present invention will be described below with reference to the accompanying drawings. This embodiment differs from the first embodiment in the number of branch portions and their cross-sectional shapes.

[0096] Such as Figure 5 As shown, the toothbrush bristle 100 has: a main body 110 and four branch parts 120 extending on the main body 110 .

[0097] The main body part 110 has a substantially columnar shape extending from the base end 111 to the tip end 121 in a state where the toothbrush bristles 100 are bristled on the flocking surface 40 . In this embodiment, the main body portion 110 is formed with a main body straight portion 112 with approximately the same diameter near the base end 111 , and is formed with a main body diameter reducing portion that is continuous with the main body straight portion 112 and gradually decreases in diameter toward the branch portion base end 122 114.

other Embodiment approach

[0110] The present invention is not limited to the above-mentioned embodiments.

[0111] In the first embodiment, the cross-sectional shape of the branch portion is approximately triangular, but the present invention is not limited thereto. The cross-sectional shape of the branch portion can also be a perfect circle, or a circle such as an ellipse; or approximately quadrilateral, or approximately five-sided. A rough polygon other than a triangle such as a side.

[0112] In the second embodiment, the cross-sectional shape of the branch portion is substantially circular, but the present invention is not limited thereto, and may be an ellipse or substantially polygonal such as substantially triangular, substantially square, or substantially pentagonal.

[0113] However, from the viewpoint of improving cleanliness, the cross-sectional shape of the branch portion is preferably polygonal. The term "polygon" refers to a substantially polygonal shape including corners cut by straight...

Abstract

The present invention relates to a bristle (1) for a toothbrush, comprising a cylindrical trunk part (10) extending from the base end (11) toward a distal end (21), and two or more branching parts (20) provided so as to extend from the trunk part (10), the branching parts (20) shaped so as to gradually decrease in diameter further toward the distal end (21), wherein the trunk part (10) of the bristle for a toothbrush has a reduced diameter part (14) that is formed near a branching part base end (22) and gradually decreases in diameter further toward the branching part (20). The branching part (20) is preferably polygonal in cross-section. The present invention is capable of providing a bristle for a toothbrush that has excellent cleaning characteristics on the tooth flank, the masticating surface, and narrow parts; that can be readily manufactured; and that is exceptionally well-suited for manufacturing a toothbrush.

Description

technical field [0001] The invention relates to a toothbrush bristle, a manufacturing method thereof and a toothbrush. [0002] This application claims priority based on Japanese Patent Application No. 2011-178830 for which it applied in Japan on August 18, 2011, and uses the content here. Background technique [0003] A common toothbrush has a handle body and a hair bundle, the handle body has: a handle portion and a head at its top end, and the hair bundle is made by binding and planting more than two toothbrush bristles on the head made. [0004] As the toothbrush bristles, there are known tapered bristles in which the diameter of the tip portion gradually decreases toward the tip, and tapered bristles, linear bristles having a substantially equal diameter from the base end to the tip, and the like. Among them, the tapered hairs are effective for preventing periodontal disease because they can enter into narrow portions such as the cervical region and the interdental po...
