[Figure 5] Figure 5 is a plan view showing an oral cleaning device according to Embodiment 5. [Modes for carrying out the invention]

[0009] The embodiments of the present invention will be described below. The embodiments shown below are one aspect of the present invention and do not limit the technical scope of the present invention.

[0010] <Embodiment 1> Figure 1 is a plan view showing an oral cleaning tool according to Embodiment 1. The oral cleaning tool 1 according to this embodiment is a cleaning tool that can remove plaque from between teeth and around teeth and gums in a single operation.

[0011] The oral cleaning tool 1 comprises a holding part 2 that can be held by the user, and a pair of support parts 3 and 4 integrally formed with the holding part 2. The holding part 2 is rod-shaped and elongated, and the support parts 3 and 4 are attached to the holding part 2. It extends in a direction perpendicular to the extension direction. Support portion 3 is positioned near the center of the holding portion 2, and support portion 4 is positioned at the tip of the holding portion 2. The holding portion 2 and support portions 3 and 4 are integrally formed from hard resin, and these are molded into a predetermined shape using a mold. The user can hold the oral cleaning tool 1 by pinching the holding portion 2 with their fingers.

[0012] A pair of support parts 3 and 4 are spaced apart and preferably extend in the same direction so as to be parallel to each other. A floss section 5 is provided at the tip end of the pair of support parts 3 and 4, stretched between the support parts 3 and 4. The floss section 5 is formed by multiple multifilament threads stretched between the support parts 3 and 4, and is composed of multiple multifilament threads bundled together. The multiple multifilament threads are passed through two through holes provided at the tip end of each of the support parts 3 and 4 and are stretched to circumfer between the support parts 3 and 4. The user can move the holding part 2 back and forth and up and down while the floss section 5 is passed between the teeth, thereby using the floss section 5 to entangle tartar and dirt accumulated between the teeth. The floss section 5 may be made up of at least one thread. The threads forming the floss section 5 may also be fuzzy. The floss section 5 is the part that is inserted between the teeth to clean them, and has the thinness and rigidity to fit between the teeth.

[0013] Furthermore, the support parts 3 and 4 are each provided with brush parts 6 and 7. The brush parts 6 and 7 are formed from a collection of multiple resin bristles, and the bristles are fixed to the support parts 3 and 4 with adhesive or the like. The brush parts 6 and 7 are the parts that come into contact with the sides of the teeth when the floss part 5 is inserted between the teeth, and polish the sides of the teeth. The bristles of the brush parts 6 and 7 generally extend in a direction perpendicular to the extending direction of the support parts 3 and 4. The bristles may also be provided around the entire circumference of the support parts 3 and 4, or only in the front-to-back direction of the oral cleaning tool 1, or only in either the front-to-back direction of the oral cleaning tool 1. The front-to-back direction of the oral cleaning tool 1 is the extending direction of the holding part 2. The user can move the holding part 2 back and forth and up and down while the floss part 5 is passed between the teeth, allowing the brush parts 6 and 7 to entangle tartar and dirt accumulated around the interdental spaces and on the gum side. The oral cleaning device 1 allows for efficient cleaning of teeth by using the floss section 5 to clean between teeth and the brush sections 6 and 7 to clean around the teeth and on the gum side.

[0014] <Embodiment 2> Figure 2 is a plan view showing an oral cleaning tool according to Embodiment 2. In Figure 2, components that are substantially the same as those in Embodiment 1 described above are denoted by the same reference numerals and their descriptions are omitted. In this embodiment, a second floss section 10 is provided in the middle of the support sections 3 and 4. The floss section 10 is made of the same material as the floss section 5 and is attached to the support sections 3 and 4 in the same manner. Parts of the brush sections 6 and 7 are arranged between the floss sections 5 and 10, and the floss sections 5 and 10 are arranged to straddle multiple bundles of bristles. The bundles of bristles between the floss sections 5 and 10 may be shorter than the bundles of bristles in other parts, and these shorter bundles of bristles can be used to more finely clean the upper surfaces of two teeth and the gum line (gum side) of the teeth. The oral cleaning tool 1 cleans the spaces between teeth with the floss sections 5 and 10, cleans the area around the spaces between teeth and the gum side with the brush sections 6 and 7, and can more finely clean the teeth with the brush sections 6 and 7 between the floss sections 5 and 10. Therefore, the oral cleaning device 1 can efficiently clean teeth.

[0015] <Embodiment 3> Figure 3 is a plan view showing an oral cleaning tool according to Embodiment 3. In Figure 3, components that are substantially the same as those in Embodiment 1 described above are denoted by the same reference numerals and their descriptions are omitted. In this embodiment, the bristles of the floss-near portion 6A of the brush portion 6 near where the floss portion 5 is attached, and the floss-near portion 7A of the brush portion 7 near where the floss portion 5 is attached, are formed to be longer than the other parts. Since teeth are spherical and cylindrical, longer bristles in the floss-near portions 6A and 7A make it easier for the bristles to contact the teeth. Also, when the pair of support portions 3 and 4 are parallel to each other, it becomes easier to insert the floss portion 5 between the teeth, allowing the floss portion 5 to clean between the teeth and the floss-near portion 7A to clean the interdental space. The surrounding areas of the teeth can be cleaned with the lateral portions 6A and 7A. Furthermore, although the support portions 3 and 4 extend parallel to each other, the present invention is not limited to this. For example, the distance between the support portions 3 and 4 at the position where the floss portion 5 is connected may be narrower than in other parts. With this configuration, in the example shown in Figure 3, the distance between the bristles of the floss near portions 6A and 7A and the opposing support portion can be shortened, making it easier to transmit information to the bristles moving the oral cleaning tool 1 and increasing the plaque removal power of the floss near portions 6A and 7A.

[0016] <Embodiment 4> FIG. 4 is a plan view showing an oral cleaning tool according to Embodiment 4. In FIG. 4, the same reference numerals are given to substantially the same components as those in Embodiment 1 described above, and the description thereof is omitted. In the present embodiment, a brush part 8 is provided on the floss part 5 side of the holding part 2 between the support parts 3 and 4. The brush part 8 is formed of the same material as the brush parts 6 and 7, and the tufts of hair are fixed to the holding part 2 by the same method as the brush parts 6 and 7. According to the oral cleaning tool 1 according to the present embodiment, by providing the brush part 8 on the holding part 2 between the support parts 3 and 4, it is possible to brush teeth from a total of four directions, namely, the three directions of the brush parts 6, 7, 8 and the one direction of the floss part 5, in one operation.

[0017] <Embodiment 5> FIG. 5 is a perspective view showing an oral cleaning tool according to Embodiment 5. In the present embodiment, the holding part 2 branches into two at the tip side, and the support parts 3 and 4 on the flat plate are connected to each of the branched holding parts 2. The holding part 2, the support parts 3 and 4 are integrally formed of resin, and the brush parts 6 and 7 are provided on substantially the entire opposing surfaces of the support parts 3 and 4 on the flat plate. In FIG. 5, the brush parts 6 and 7 are partially shown, and the illustration of all of the brush parts is omitted. Also, a floss part 5 is laid between the support parts 3 and 4. The oral cleaning tool 1 according to the present embodiment polishes the side parts of the teeth with the brush parts 6 and 7 while cleaning between the teeth with the floss part 5. Since the support parts 3 and 4 are planar, the brush parts 6 and 7 are formed in a planar shape, and the side parts of the teeth can be polished in a planar manner. For this reason, the oral cleaning tool 1 can polish the entire side parts of the teeth without omission by simply moving the tool back and forth without rotating or moving the holding part 2 up and down. Note that the support parts 3 and 4 may be circular, elliptical, or spherical according to the shape of the teeth.

[0018] <Other Embodiments> In the above embodiments, the brush parts 6 and 7 are provided on both of the support parts 3 and 4, but the present invention is not limited to this. For example, the brush part may be provided on at least one of the support parts 3 and 4.

[0019] The features included in each of the embodiments and modifications disclosed above can be combined with each other. [Explanation of symbols]
