Brief Description of the Drawings
[0008] [Figure 1] FIG. 1 is a plan view showing an oral cleaning tool according to Embodiment 1. [Figure 2] Figure 2 shows the molars being cleaned with the oral cleaning device according to this embodiment. [Figure 3] Figure 3 is a plan view showing an oral cleaning device according to Embodiment 2. [Figure 4] Figure 4 is a plan view showing an oral cleaning tool according to Embodiment 3. [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 is worn on the user's finger and used for cleaning between teeth.
[0011] The oral cleaning tool 1 comprises a finger-shaped main body 2. The main body 2 is formed from a sheet material and has a vertically elongated cylindrical shape. The user's finger or a rod-shaped tool can be inserted into this cylindrical main body 2. The main body 2 has one end (tip) closed in the longitudinal direction and an opening 3 formed at the other end (base). The oral cleaning tool 1 is used for cleaning the inside of the mouth with a finger or rod-shaped tool inserted into the main body 2 through this opening 3. One end of the main body 2 is formed in a tapered shape to fit the finger. The feel has been improved. Also, although the main body 2 is made of resin, it may be made of paper coated with resin.
[0012] The oral cleaning tool 1 according to this embodiment is provided with a curved, return brush 6 (an example of the "brush portion" in this disclosure) that is attached to one end (tip side) of the main body 2 and extends in a curved shape toward the terminal side. The return brush 6 is formed from an aggregate of resin bristles and is curved toward the terminal side so that it can clean areas of the back teeth that are difficult to reach with a toothbrush.
[0013] The bristles of the return brush 6 are spread out within a length B along the width direction of the main body 2, extending from the side of the main body 2. It is generally known that the interdental spaces of the molars are areas where plaque buildup is significantly present when brushing with a toothbrush. The oral cleaning tool 1 according to this embodiment is suitable for cleaning molars. Figure 2 shows the state of cleaning the molar 100, which is located at the very back of the oral cavity, with the oral cleaning tool 1 according to this embodiment. By pressing the return brush 6 against the back side of the molar 100 and rubbing, plaque buildup on that back side can be removed. For example, if the index finger is inserted into the main body 2 and the return brush 6 is inserted into the back of the oral cavity along the side of the tooth, the return brush 6 can be brought into contact with the back side of the molar 100 as shown in Figure 2. If the width of the molar 100 is A, the number of bristles, the curvature shape of each bristle, the length, etc. of the return brush 6 are set so that B > A. This allows the bristles of the return brush 6 to come into contact with almost the entire back side of the molar 100. Furthermore, because the return brush 6 is curved, simply by moving the main body 2 back and forth in the direction of the back and front of the oral cavity, the bristles of the return brush 6 can be guided along the back side of the molars 100, and the return brush 6 can be moved back and forth in the width direction on the back side of the molars 100. The oral cleaning tool 1 according to this embodiment can also clean areas that are missed when brushing teeth with a toothbrush.
[0014] Furthermore, the oral cleaning tool 1 can also clean the spaces between the back teeth using the curved brush 6. By inserting the curved brush 6 between the teeth, it is possible to remove plaque from the spaces between the back teeth, where plaque is often missed during brushing.
[0015] Further, the oral cleaning tool 1 is provided on the surface (side surface) of the main body portion 2 and includes a polishing portion 5 for polishing teeth. The polishing portion 5 may be a high-friction portion that generates a greater frictional force than other parts of the main body portion 2. The high-friction portion can be formed, for example, by adhering a sheet subjected to embossing to the surface of the main body portion 2. The polishing portion 5 is disposed on the side surface side in the extending direction of the reverse brush 6. The user can polish the surface of the teeth with the polishing portion 5 while cleaning between the teeth with the brush portion 4 with the index finger inserted into the main body portion 2. The oral cleaning tool 1 according to the present embodiment can clean between the teeth and the surface of the teeth simultaneously.
[0016] Also, the polishing portion 5 may be formed of a bristle material having shorter bristle legs than the bristle material constituting the reverse brush 6. By forming the polishing portion 5 of a bristle material having short bristle legs, the surface of the teeth, the gingival side of the teeth, and the periphery between the teeth can be finely polished by the polishing portion 5. The oral cleaning tool 1 according to the present embodiment enables polishing between the teeth and on the side portions of the teeth and can be used for multiple purposes, so it is easy to handle.
[0017] <Embodiment 2> FIG. 3 is a plan view showing an oral cleaning tool according to Embodiment 2. The oral cleaning tool 1 includes a brush portion 4 (an example of the "brush portion" of the present disclosure) fixed to the main body portion 2 and formed including a plurality of bristle materials. The brush portion 4 has a core 40 which is a thin wire made of metal, and a bristle material 41 fixed to the core 40. The core 40 is fixed to the surface of the main body portion 2 so as to extend perpendicularly from the surface of the main body portion 2. The core 40 is folded back in two at the tip side of the wire, and the bristle material 41 is fixed by twisting the wire with the bristle material 41 passed between the double wires thus formed. The user can clean between the teeth with the brush portion 4 with the index finger inserted into the main body portion 2. The user may clean between his or her own teeth, or may clean between the teeth of others such as infants or the elderly. The oral cleaning tool 1 according to the present embodiment can be attached to a finger or a jig, so it is easy to handle.
[0018] Further, the polishing portion 5 may be formed of bristles that are shorter than the bristles constituting the brush portion 4. By forming the polishing portion 5 of bristles with short bristle feet, the surface of the teeth, the gingival side of the teeth, and the periphery between the teeth can be finely polished by the polishing portion 5.
[0019] Further, the oral cavity cleaning tool 1 is provided on the surface (side surface) of the main body portion 2 and includes a polishing portion 5 for polishing teeth. The polishing portion 5 is disposed on the side surface on the extending direction side of the brush portion 4. Here, when the main body portion 2 is viewed in the width direction, the brush portion 4 and the polishing portion 5 are arranged with a gap therebetween. When cleaning between teeth, the oral cavity cleaning tool 1 moves back and forth with respect to the space between teeth to clean between teeth with the brush portion 4. Further, when polishing the surface of the teeth, the oral cavity cleaning tool 1 brings the polishing portion 5 into contact with the teeth in a state where the brush portion 4 is shifted so as not to contact the teeth, and moves in the surface direction of the teeth, whereby the side portion of the teeth can be polished. As described above, the oral cavity cleaning tool 1 according to the present embodiment enables polishing between teeth and on the side portion of the teeth, and can be used for multiple purposes, so it is easy to handle.
[0020] <Embodiment 3> FIG. 4 is a plan view showing an oral cavity cleaning tool according to Embodiment 3. In FIG. 4, the same reference numerals are given to substantially the same configurations as those in the above-described Embodiments 1 to 3, and the description thereof is omitted. The oral cavity cleaning tool 1 according to the present embodiment is provided with cleaning pieces 7 on the side surface in the extending direction of the return brush 6. Thus, the oral cavity cleaning tool 1 may include the return brush 6 and the cleaning pieces 7. The oral cavity cleaning tool 1 according to the present embodiment enables polishing between teeth, on the side portion of the teeth, and in the periodontal pocket, and can be used for multiple purposes, so it is easy to handle.
[0021] Further, the main body portion 2 includes a fitting portion 10 that fits with a jig or a finger in the vicinity of the opening portion 3. The fitting portion 10 is provided on the inner wall surface of the main body portion 2 and is a portion that partially reduces the inner diameter in the vicinity of the opening portion 3. Two fitting portions 10 are provided discretely, and it is possible to prevent a jig inserted symmetrically from being engaged with a groove or a finger root from coming out of the main body portion 2. Note that a plurality of fitting portions 10 may be provided discretely, or may be provided continuously along the entire circumference of the inner wall. The fitting portion 10 is preferably arranged in a circumferential shape on the inner wall.
[0022] Alternatively, instead of the fitting portion 10, an elastic member may be placed in an extended state on the open end side of the opening 3, and the opening 3 may be contracted by the contraction force of the elastic member. In this way, it is preferable that the oral cleaning tool 1 has a structure that prevents fingers or jigs from slipping out of the opening 3.
[0023] <Other Embodiments> The fitting portion 10 of Embodiment 4 described above is of course also applicable to Embodiments 1 to 3. Furthermore, the oral cleaning tool 1 may also include the return brush 6, the brush portion 4, and the cleaning piece 7.
