Description

  The present invention relates to a tooth cleaning tool that removes plaque, eating residue and the like between teeth, and at the same time polishes the interdental part and the boundary part of the gums.

  It is a well-known fact that a brush with dental floss, which is a thread for interdental cleaning with fine nylon fibers and the like, is effective in preventing tooth decay and periodontal disease.

  As a technique related to this kind of toothbrush, many techniques have been proposed and put into practical use.

  As an example, Japanese Patent Application Laid-Open No. 2007-130418 discloses a floss yarn brush with an interdental brush function, and Japanese Patent Application Laid-Open No. 2-289246 discloses a tooth cleaning device.

  By the way, since the thing disclosed by these Unexamined-Japanese-Patent No. 2007-130418 and Unexamined-Japanese-Patent No. 2-289246 is all, the dental floss is stretched on the outer side of a toothbrush, Therefore Insert dental floss between teeth. If you polish, the position of dental floss and toothbrush will be separated. For this reason, there is a problem that dental floss does not accurately guide the toothbrush to sites that are difficult to polish, such as the interdental part and the boundary of the gums, so that unfinished brushes are likely to occur.

JP 2007-130418 A JP-A-2-289246

  The problem to be solved by the present invention is that the dental floss is outside the toothbrush and not on the center line of the toothbrush, so if the dental floss is inserted between the teeth and polished, The position of the toothbrush is separated, and the dental floss does not accurately guide the toothbrush to a region where it is difficult to polish, such as the interdental part and the boundary of the gums, and it is easy to leave unpolished.

  Accordingly, an object of the present invention is to provide an accurate dental floss by stretching the dental floss, which is a thread for interdental cleaning, to the inner center (center of the toothbrush base material) of two opposing toothbrush portions. It is an object of the present invention to provide a tooth cleaning tool that can automatically polish the periphery of the interdental part and the boundary of the gums evenly without any bias.

  In addition, an object of the present invention is to make each of the two toothbrush parts detachable from each of the two support parts, thereby enabling replacement of the toothbrush part due to consumption of the toothbrush part, etc. The object is to provide a tooth cleaning tool that can be used.

  For this purpose, the tooth cleaning tool according to claim 1 of the present invention includes a gripping portion 1, two support portions 3, 3 a that are connected to the gripping portion 1 and are bifurcated to form a bifurcated shape. Notches 7 and 7a for horizontally stretching the dental floss 6 are provided at the tip portions of the brush base parts 5 and 5a connected to the support parts 3 and 3a, respectively, and the two brush base parts 5 and 5a are provided. Each of the brush portions formed by flocking the flocked bundles 9 and 9a on the circumference centering on the deepest portions a and b of the cutout portions 7 and 7a. 4, 4 a, a bulge formed in the vicinity of the bifurcated bifurcated portion or in the grip portion 1, and a take-up fastening portion 10 for taking up and fastening both ends of the dental floss 6, The two brush base parts 5 through the notches 7, 7a, It is characterized by a construction stretched on the center line between 5a.

  The tooth cleaning tool according to claim 2 of the present invention is characterized in that the two brush portions 4, 4a are connected to the two support portions 3, 3a so as to be detachable. It is.

  According to the first aspect of the present invention, the dental floss, which is a thread for interdental cleaning, is stretched on the inner center (center of the toothbrush base material) of the two toothbrush portions facing each other. Since the floss accurately guides the two toothbrush parts, the surroundings such as the interdental part and the boundary of the gums can be automatically polished evenly.

  In addition, according to the invention described in claim 2, each of the two toothbrush portions can be attached to and detached from each of the two support portions, so that the toothbrush portion can be replaced due to the consumption of the toothbrush portion. Can be used economically.
