Abstract

PROBLEM TO BE SOLVED: To effectively massage gums without damaging by forming the mix implanting part of rubber-like bar brushes and brush tufts having softness of a degree for avoiding damaging of the gums at the outer peripheral part of a bristle implanting base surface and forming the bristle implanting part of brush tufts harder than the brush tufts of the outer peripheral part in the center of the bristle implanting base surface. SOLUTION: A bristle planting base 10 is successively formed at the tip of a handle 11, and brush tufts 20 having softness of a degree for avoiding damaging of the gums and rubber-like bar brushes 30 are mix-implanted alternately and in the state of the same line along an outer peripheral part excepting for the center of the handle-side edge part 10d of the bristle implanting base surface 10a of the base 10. In addition, concerning each of the brushes 30, a matter having a nearly triangle cross section widening its outer peripheral side compared with the center side of the base 10 is implanted to be easily bent to the outer peripheral side of the base 10 when in use. In addition a corner part of the nearly triangle form is properly rounded to obtain a soft contact feeling.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to the removal of plaque,
The present invention relates to a toothbrush capable of massaging gums.

[0002]

2. Description of the Related Art As a toothbrush for removing gums and massaging gums, for example, a mixture of a rubber-like rod-shaped brush and a brush bundle is already known. However, since the brush bundle in such a conventional toothbrush is planted so that its hardness is all uniform, a soft brush bundle can only obtain a low plaque removing effect, and conversely a hard brush. In the case of a bundle, there is a problem that the gums are easily damaged.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the conventional toothbrush, and provides a toothbrush capable of effectively massaging the gum without damaging the gum and obtaining a high plaque removing effect. The purpose is to provide.

[0004]

In order to achieve the above-mentioned object, the present invention provides a toothbrush comprising a rubber-like rod-shaped brush and a brush-bundle having a softness enough not to damage gums on the outer periphery of a flocking table surface. In addition, a bristle implantation portion of a brush bundle that is harder than a brush bundle of an outer peripheral portion is formed in an inner central portion of the flocking table surface.

The difference between the hardness and the softness between the inner brush bundle and the outer brush bundle is not limited irrespective of the specific means.
For example, it is simple and advantageous to provide the brush bundle by changing the elasticity, length or thickness of the inner and outer brush bundles or the thickness of each of the brushes constituting the brush bundle.

[0006] The soft brush bundle on the outer peripheral portion may be one in which a plurality of rows are implanted inward from the outer peripheral end of the flocking table surface. However, it is desirable to obtain a high plaque removing effect by the hard brush bundle in the inner central part.

The rubber-like bar-shaped brush mixed with the soft brush bundle on the outer peripheral portion may be planted over the entire outer peripheral portion of the flocking table surface, but only the long side edge of the flocking table surface is planted. This is preferable in order to obtain an effective gum massage effect. As the rubber-like brush, a brush having a cross-sectional shape such as a substantially triangular shape or a substantially trapezoidal shape which is wider on an outer peripheral side than an inner central side of the flocking table is used. As a result, it is possible to efficiently massage up to the gingival margin by its elastic sliding action, which is advantageous.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

Reference numeral 10 designates a flocking table coupled to the tip of the handle 11, which is soft enough to damage only one row of gums along the outer periphery of the flocking table surface 10a except the center of the handle side edge 10d. The brush bundles 20 having different lengths and the rubber-like bar-shaped brushes 30 are mixed alternately and in the same row. Incidentally, the rubber-like rod-shaped brush 30 is provided with the opposed longitudinal edges 1 of the flocking table surface 10a.
0b, and is not planted at the front edge 10c and the pattern side edge 10d.

[0010] Here, the rubber-like bar-shaped brush 30 is attached to the flocking table 10.
A plant having a substantially triangular cross-sectional shape that is wider on the outer peripheral side than the inner central side is planted, so that it is easy to bend on the outer peripheral side of the flocking table 10 during use. . The corners in the substantially triangular shape are appropriately rounded to obtain a soft touch feeling. The material of the rubber-like brush 30 may be rubber, synthetic resin, or the like, but is preferably styrene / butadiene rubber, ethylene / propylene rubber, silicone rubber, or the like.

On the other surface portion of the flocking table surface 10a, that is, on the inner central portion, a suitable number of brush bundles 21 which are harder than the brush bundle 20 on the outer peripheral portion are planted so as to obtain a sufficient plaque removing effect. Here, the brush bundle 21 at the inner central portion and the brush bundle 2 at the outer peripheral portion
The difference in hardness and softness from 0 is given by appropriately changing the elasticity, length or thickness of the brush bundle as described above.
The material of the brush bundles 20 and 21 may be natural hair or artificial hair such as nylon or polybutylene terephthalate.

[0012]

When the toothbrush of the present invention is used, the gums can be effectively massaged with a rubber-like brush, and in addition, the brush bundle on the outer peripheral portion is soft, so that the gums are not damaged and the inner central portion is not damaged. Since the brush bundle is hard, a high plaque removing effect can be obtained.

Claims (5)

[Claims] 1. A mixed planting portion of a rubber-like bar-shaped brush and a brush bundle having a degree of softness so as not to damage gums is formed on an outer peripheral portion of a flocking table surface, and an outer peripheral brush bundle is formed on an inner central portion of the flocking table surface. A toothbrush that has a flocked portion of a stiffer brush bundle. 2. The difference between the hardness and the softness between the inner bundle and the outer bundle is determined by the elasticity, length or thickness of the brush bundle, or the thickness of each of the brushes constituting the brush bundle. 2. The toothbrush according to claim 1, wherein the toothbrush is provided by a difference. 3. The toothbrush according to claim 1, wherein the brush bundle at the outer peripheral portion is only one row of the outermost peripheral row along the outer peripheral portion of the flocking table surface. 4.
