Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a toothbrush.

2. Description of the Related Art Conventional technology and its problems There are hair bundles that are planted on a brush base of a toothbrush with various rigidity, but conventionally, most hair bundles that are planted on one toothbrush have the same rigidity. .

A toothbrush provided with a highly rigid bristle bundle is effective for removing deposits, plaque, etc. on the tooth surface. Further, since it is a bristle bundle, the bristle bundle is less likely to bend at the waist and easily enters the tooth gap, which is suitable for removing the deposits in the gap. However, in the brushing with the above toothbrush, the teeth may be worn down or the gums may be damaged in combination with the polishing action of the abrasive compounded in the dentifrice.

On the other hand, a toothbrush having a bristles with low rigidity can reduce the damage to the teeth and gums as described above, but since it is a bundle of bristles that is highly flexible, it does not easily break into the gaps between the teeth, resulting in a gap between the teeth. There is a problem in that it is impossible to sufficiently remove deposits and the like that strongly adhere to the.

As a means for dealing with this, a toothbrush in which soft bristles and hard bristles are alternately arranged vertically and horizontally (Japanese Utility Model Publication No. 52-81355) has been proposed. However, since the toothbrush has both hard and soft bristles formed with the same diameter, when the whole is made of thin filaments, the thin hard bristles easily damage the teeth and gums, and the whole is made of thick filaments. in case of,
There has been a problem that it becomes difficult to remove the interdental deposits due to the penetration between the teeth.

An object of the present invention is to solve the above problems and to provide a toothbrush capable of efficiently and sufficiently cleaning teeth and tooth gaps, and capable of reducing damage to teeth and gums due to brushing. .

Means for Solving the Problems The above-mentioned object of the present invention is to provide a brush base at the tip of a handle with two types of hair bundles having different rigidity by making the filament diameters different from each other, alternately in a hair bundle unit. This is achieved by a toothbrush characterized by being planted in a pattern.

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

1 and 2 show a toothbrush according to an embodiment of the present invention. This toothbrush includes a rod-shaped handle (1) and a brush base (2) provided at the tip of the handle (1). On the brush stand (2), the diameter of each bundled filament is large, and thus the bristle bundle (3) to which relatively high rigidity is imparted, and the bundled filaments each have a small diameter, which results in flexibility. Rich bristles (4) are alternately planted in a checkered pattern at predetermined intervals, and the tips of these bristles, bristles (3) and (4) are aligned at the same height. Has been.

By brushing with a tooth using the toothbrush of the present invention constructed as described above, the adherents, plaque and the like on the tooth surface are sufficiently removed by the rigid and soft bristles (3) and (4). In addition, the adhered matter or the like fixed to the tooth gap is not only the cleaning action by the filament of the bristles bundle (3) that easily penetrates into the tooth gap,
It is also removed by the brushing action of the filaments of the bristles (4) that are pressed by the bristles (3) and introduced into the gap, and are efficiently and sufficiently cleaned. Moreover, the toothbrush of the present invention has the bristle bristles (3) and the villi bristles (4) alternately planted, and the bristles bristles (3) are formed of thick filaments. Damage to teeth and gums during brushing is reduced as compared to a toothbrush in which only a bundle is planted and a toothbrush in which a bristles bundle is formed of thin filaments.

The bristles (4) have a small amount of filaments forming them and are weak, but the bristles (3) surrounding the bristles (4) at the time of brushing have the rigidity and thus the bristles (4). ), The extreme bending of the bristles (4) is prevented. As a result, the bristles (4) are unlikely to be in an open state due to the bending of the waist of each filament, and the toothbrush of the present invention can be used for a long period of time.

EFFECTS OF THE INVENTION As is apparent from the above, according to the present invention, two types of bristle bundles having different rigidity in each bristle bundle due to different filament diameters are alternately arranged in a checkerboard pattern. As a result, it is possible to provide a toothbrush that can efficiently clean the teeth and deposits between the teeth and the like, and can reduce damage to the teeth and gums due to brushing.
