Embodiment 1～ Embodiment 3、 comparative example 1～ comparative example 6

[0107] according to Figure 4 specifications shown, with figure 1 Like toothbrush 1, a toothbrush with implanted ST bristles (made of PBT) was made. This toothbrush 1 includes an inner bristle group composed of inner bristle bundles implanted in a zigzag pattern, and a pair of outer bristle bundle groups composed of outer bristle bundles implanted in a zigzag shape, respectively, sandwiching the inner bristle bundle group. Each of the first outer hair bundle group and the second outer hair bundle group is composed of the same number of outer hair bundles.

[0108] In the table, "the number of inner bristles corresponding to each bundle of inner hair bundles" refers to the number of inner bristles forming one bundle of inner hair bundles, and "the number of outer bristles corresponding to each bundle of outer hair bundles" refers to the number of bristles forming one bundle of outer hair bundles. The number of outer bristles of the bundle. The specifications related to the o...

Embodiment 4～ Embodiment 6

[0110] according to Figure 4 specifications shown, with image 3 As with toothbrush 1A of , a toothbrush with implanted ST bristles (made of PBT) was made. This toothbrush 1A includes an inner bristle bundle group composed of inner bristle bundles implanted in a grid pattern, and a pair of outer bristle bundle groups composed of outer bristle bundles implanted in a grid shape, respectively, sandwiching the inner bristle bundle group. Each of the first outer hair bundle group and the second outer hair bundle group is composed of the same number of outer hair bundles. For the obtained toothbrushes of each example, the feeling of massaging, the feeling of entering the neck of the tooth, and the cleaning power of the neck of the tooth were evaluated.

[0111] Such as Figure 4 As shown, in the examples 1 to 6 of the present invention, the evaluations of the feeling of massage, the feeling of entering the neck of the tooth, and the cleaning power of the neck of the tooth are al...

Abstract

The purpose of the present invention is to provide a toothbrush that has a gentle massage feeling on a wide range of gums while ensuring high sweeping performance on the neck of the teeth. It has a handle body (2) with a brush head (4) at the front end, and hair bundles of bristles are implanted in a plurality of hair-planting holes formed on the hair-planting surface (5) of the brush head. The hair-planting surface has: an inner hair-planting area (11), wherein multiple bundles of inner hair bundles are arranged in parallel in the direction of the handle body axis (O), and are implanted in the approximate center of the width direction perpendicular to the axis; and the outer hair-planting area ( 21), wherein multiple bundles of outer hair bundles are implanted with the inner hair bundles sandwiched in the width direction, and the maximum length L of all the hair-planting areas where multiple bundles of inner hair bundles and multiple bundles of outer hair bundles are implanted in the width direction is 12.0mm ~16.0mm; the maximum length of the outer hair-planting area in the width direction is 6.5mm-9.5mm; the maximum length of the inner hair-planting area in the width direction is 4.0mm-5.5mm; the diameter of the outer hair bundle is 1.4mm-1.8mm; Hair bundle The diameter of the hair bundle is 1.0 mm to 1.4 mm.

Description

In addition, in recent years, the obvious "gentle massage feeling on the gums" has also been valued by consumers. However, in conventional periodontal disease prevention toothbrushes, the focus is on a compact brush head, and the amount of hairs that touch the gums during normal brushing is small, so sufficient massaging effects cannot be obtained. Therefore, a toothbrush with tufts touching a wide range of gums and having a high tooth neck sweeping force is ...
