Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a toothbrush.

[0002]

[0003]

[Problems to be solved by the device]

 Generally, the tips of toothbrushes are rounded so that there are no sharp parts to prevent damage to the gums, and the cross-sectional shape of the bristles is also circular. However, the effect is not sufficient even if the food waste is scraped out or the food waste is scraped out, and there is a problem that the teeth must be brushed for a long time.

[0004]

[Purpose of the invention]

[0005]

[Means for Solving the Problems]

 The toothbrush according to the present invention is characterized in that, in the toothbrush formed by implanting a large number of synthetic resin bristles in the bristles of the toothbrush body, the cross-sectional shape of the bristles is a polygon having a large number of acute-angled portions. It is a thing.

[0006]

[Function of the invention]

 When brushing teeth by gripping the handle of the toothbrush body and rubbing the teeth, you only rub the surface of the tooth with the tips of the bristles like a conventional toothbrush. Since a large number of sharp corners are formed in this area, scrape off the food residue adhering to the teeth at this part, and in the case of food waste clogged between the teeth, insert the tips of the hairs between the teeth. If the handle is rolled, not only will it be scratched out by the tips of the hair, but the side of the tooth will be rubbed by the sharp edge of the side of the hair, allowing for a beautiful polish.

[0007]

[Embodiment of the invention]

 An embodiment of the toothbrush of the present invention will be specifically described with reference to the drawings. FIG. 1 is a plan view of a toothbrush of the present invention, FIG. 2 is a side view of the same, and FIG. 3 is an enlarged sectional view of bristles implanted in the toothbrush. Reference numeral 1 denotes a toothbrush body, which is composed of a bristle portion 11 and a handle 12 and a large number of synthetic resin bristles 2 ... 2 are planted in the bristle portion 11.

The bristles 2 are formed by extruding a molten synthetic resin liquid from a polygonal nozzle having a large number of acute-angled cross sections, and the bristles 2 have the same cross-sectional shape as the nozzle.

[0009]

[Effect of the invention]

 According to the toothbrush of the present invention, the cross-sectional shape of the bristles to be planted in the bristling part of the toothbrush main body is a polygon having a large number of sharp corners.
