no. 1 approach

[0072] Refer to the following Figure 1A as well as Figure 1B The toothbrush according to the first embodiment of the present invention will be described.

[0073] Figure 1A as well as Figure 1B The toothbrush 1 shown has a brush head 2 and an elongated handle 3 extending from the brush head 2, and has a first hair bundle group 30 and a second hair bundle group on the hair-planting surface 20 of the brush head 2 40. Figure 1A as well as Figure 1B In, the code|symbol 22 has shown the one side edge of the width direction of the brush head part 2, and the code|symbol 24 has shown the other side edge of the width direction of the brush head part 2. In addition, the width direction of the brush head 2 is a direction perpendicular to the direction from the head tip 21 toward the boundary between the head 2 and the handle 3 (the base of the head).

[0074] The first hair bundle group 30 is arranged in the approximate center of the hair-planting surface 20, starting from the b...

no. 2 approach

[0112] Refer to the following Figure 2A as well as Figure 2B The toothbrush according to the second embodiment of the present invention will be described.

[0113] In addition, the same code|symbol is attached|subjected to the same structure as 1st Embodiment, and description is abbreviate|omitted, and the point which differs from 1st Embodiment is mainly demonstrated.

[0114] Figure 2A as well as Figure 2B The toothbrush 100 shown has a first tuft group 130 and a second tuft group 140 on the flocking surface 20 .

[0115] In the toothbrush 100, the distance L3 from the second hair bundle 42 closest to the brush head top 21 to the second hair bundle 42 closest to the brush head base end is, from the second hair bundle closest to the brush head top 21 42 to less than 1 / 2 of the distance L1 from the first hair bundle 32 closest to the base end of the brush head. And, between the region with the second hair bundle group 140 and the base end of the brush head, the first ...

no. 3 approach

[0121] Refer to the following Figure 3A as well as Figure 3B The toothbrush according to the third embodiment of the present invention will be described.

[0122] In addition, the same code|symbol is attached|subjected to the same structure as 1st Embodiment, and description is abbreviate|omitted, and the point which differs from 1st Embodiment is mainly demonstrated.

[0123] Figure 3A as well as Figure 3B The toothbrush 200 shown has a first bristle group 230 and a second bristle group 240 surrounding it, a first bristle group 232 and a second bristle group 242 surrounding it on the flocking surface 20 .

[0124] The first hair bundle group 230 is arranged in an area below 50% of the hair-planting area from the top end 21 of the brush head to the base end of the brush head, that is, more than 0% of the length from the top end 21 of the brush head to the base end of the brush head. The hair-planting area below 50% is planted with first hair bundles 32 in the manner of...

Abstract

Provided is a toothbrush that can satisfactorily clean an interdental region and a tooth cervix as well as a tooth surface and an occlusal surface of a molar. A toothbrush (1) has two or more bristle bundles implanted in an implantation surface (20) of a head part (2), each of which bristle bundles comprising two or more bristles. The toothbrush (1) is provided with a first bristle bundle cluster (30) and a second bristle bundle cluster (40). The first bristle bundle cluster (30) has at least one implanted first bristle bundle (32); and the second bristle bundle cluster (40) has a second bristle bundle (42) implanted around the first bristle bundle cluster (30), and opening toward a distal end or a proximal end of the head part (1). The length of the first bristle bundle (32) is shorter than the length of the second bristle bundle (42), and the buckling strength of the first bristle bundle (32) is lower than the buckling strength of the second bristle (42).

Description

technical field [0001] The present invention relates to a toothbrush. [0002] This application claims priority based on Patent Application No. 2011-040060 filed in Japan on February 25, 2011, the contents of which are cited here. Background technique [0003] Sites prone to caries (sites prone to corrosion) were considered to be molars, interdental portions, and tooth necks. For cleaning the molars, it is important to exert high pressure on the occlusal surface and the tooth surface, so it is suitable for the bristle bundle with high rigidity and high density. On the other hand, for cleaning the interdental portion and the neck of the tooth, the ability to insert the hair bundle into a narrow area such as the interdental or periodontal pocket and the soft touch are important, so a thin and low-rigidity hair bundle is used. As described above, toothbrushes suitable for cleaning molars, interdental parts, and tooth necks have different specifications. Therefore, in order to...
