DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothbrush capable of effectively performing gum massage as well as plaque removal, and more particularly to a toothbrush having a rubber-like straight rod brush for gum massage.

[0002]

2. Description of the Related Art As a toothbrush for the purpose of massaging a gum, for example, a tongue-shaped rubber massager attached to a longitudinal edge of a flocking table surface (Japanese Utility Model Laid-Open No. 47-173) is known.
No. 8) and a rubber brush having a tip bent outward (Japanese Utility Model Application Laid-Open No. 62-35527) are already known. However, in the former case, the rubber massager is in the shape of a tongue and protrudes below the brush bundle, so it is almost impossible to brush it vertically or diagonally, even when brushing horizontally. The massage effect cannot be obtained, and in the latter case, since the tip of the rubber brush is bent from the beginning, it is difficult to transmit power to the gums and only a low massage effect can be obtained. In fact, the conventional toothbrush did not yet provide a satisfactory gum massage effect.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a toothbrush which solves the above-mentioned problems of the conventional toothbrush and which provides a high massage effect on gums, especially on the margins and nipples. Aim.

[0004]

In order to achieve the above object, a toothbrush according to the present invention is provided with a rubber-like straight rod-shaped brush that is inclined outward at least on a part of a long side edge of a flocking table surface. It is configured.

According to this configuration, the rubber-like straight rod-shaped brush is a straight rod-like body that is not bent to the tip end, so that a force is easily applied to the gums when brushing in any of vertical, horizontal and diagonal directions. As a result, a high massage effect is obtained, and since it is inclined outward, the plaque removing action of the brush bundle planted on the flocking table surface is not hindered at all. By the way, the inclination angle of the rubber-like straight rod brush is 2 to 15 degrees in the outward direction of the longitudinal edge with respect to the vertical line.
It is preferable to set the degree.

Here, at least a part of the rubber-like straight rod-shaped brush is made to protrude from the tip of the brush bundle planted on the flocking table surface, so that it becomes easier to hit the marginal gingival part and the interdental papilla. Advantageously, the edge and nipple can be massaged simultaneously and efficiently. By the way,
The degree of the protrusion is preferably about 0.5 to 3.0 mm.

In this case, the rubber-like straight rod-shaped brush is planted alternately with the brush bundle at least at a part of the long side edge of the flocking table surface. As a result, it is easy to reach the interdental papilla, which is desirable for obtaining a more effective massage effect.

In order to achieve the above object, the toothbrush of the present invention has a rubber-like straight rod-shaped brush protruding from at least a part of a longitudinal edge of a flocked table surface alternately with a brush bundle and from the tip of the brush bundle. At least it was constructed by planting it upright.

According to this configuration, as described above, since the rubber-like brush has a straight rod shape, a force is easily applied to the gums when brushing in any of the vertical, horizontal and diagonal directions. As a result, a high massage effect is obtained. As it protrudes from the tip of the brush bundle planted on the flocking table surface, it becomes easier to hit the interdental papilla, especially the marginal gingival part, so that the margin of the gum and the papilla are simultaneously
Moreover, massage can be performed efficiently.

In the present invention, the rubber-like straight rod brush has a cross-sectional shape such as a substantially triangular shape or a substantially trapezoidal shape which is wider on the outer peripheral side than on the inner central side of the flocking table. As a result, the material easily bends to the outer peripheral side of the flocking table during use, and as a result, it is possible to efficiently massage up to the marginal gingival part by its elastic sliding action, which is advantageous.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a first embodiment, in which a flocking table surface 10a of a flocking table 10 coupled to a tip of a handle 11 is shown.
A rubber-like straight rod-shaped brush 20 having a rounded top portion is implanted at an opposite longitudinal edge 10b at an angle of about 10 ° outward from the longitudinal edge 10b. The tip of the rubber-like straight rod-shaped brush 20 is aligned substantially on the same horizontal plane as the tip of the brush bundle 30 that is planted upright on the flocking table surface 10a, and at the longitudinal edge 10b,
The rubber-like straight rod-shaped brushes 20 and the brush bundles 30 are alternately arranged in the same row.

According to this embodiment, since the rubber-like straight rod-shaped brush 20 is a straight rod-like body that is not bent to the tip end, a force is easily applied to the gum in any direction. Since a high massage effect is obtained and the taper is inclined outward, it does not hinder the plaque removing action of the brush bundle 30 implanted on the implanted table surface 10a.

The rubber-like straight rod-shaped brush 20 has a substantially triangular cross-sectional shape that is wider on the outer peripheral side than on the inner central side of the flocking table 10. The outer periphery of the table 10 is easily bent. Further, the corners in the substantially triangular shape are appropriately rounded so that a soft touch feeling can be obtained.

The material of the rubber-like straight rod brush 20 may be any material such as rubber such as styrene-butadiene rubber, ethylene-propylene rubber, silicone rubber or a synthetic resin, and the material of the brush bundle 30 may be natural. It does not matter whether hair or artificial hair such as nylon or polybutylene terephthalate is used.

FIG. 2 shows a second embodiment, in which the tip of a rubber-like straight rod brush 20 protrudes about 2 mm from the tip of a brush bundle 30 which is planted upright on the flocking table surface 10a. Other than that, the configuration is the same as that of the first embodiment shown in FIG. That is, the rubber-like straight rod-shaped brushes 20 in this embodiment are implanted so as to be inclined outwardly of the longitudinal edges 10b of the flocking table surface 10a and protrude from the brush bundle 30.

According to this embodiment, since the rubber-like straight rod-shaped brush 20 protrudes from the brush bundle 30,
A more excellent massage effect on the margins of the gums and the nipple can be obtained.

FIG. 3 shows a third embodiment, except that the rubber-like straight rod brush 20 is planted upright without being inclined on the flocking table surface 10a. The configuration is the same as that of the embodiment. That is,
The rubber-like straight rod-shaped brushes 20 in this embodiment are planted in an upright state alternately with the brush bundle 30 and protruding from the tip of the brush bundle 30.

According to this embodiment, since the rubber-like straight rod-shaped brush 20 does not concentrate on one place and protrudes from the brush bundle 30, the peripheral portion of the gum and the nipple Excellent massage effect can be obtained.

[0020]

By using the toothbrush of the present invention, not only plaque can be removed but also a high massage effect can be obtained on the gums, especially on the margins and the nipple.
