  The periodontal cleaning tool 10 includes a handle portion 11, which is a first handle portion, a first shaft portion 12, a second shaft portion 13, a third shaft portion 14, and a periodontal cleaning portion 15. However, it is formed by integral molding using engineering plastic (engineering plastic).

  The handle portion 11 is formed in an arc shape having the same curvature as the upper and lower outer peripheral portions 11a, and the left and right side surfaces 11b and 11c are formed as flat surfaces. That is, it is formed in a shape suitable for picking with the thumb on one side 11b of the handle 11 and the index finger and middle finger on the other side 11c. Further, the length of the handle 11 is formed to a length suitable for picking with the thumb, forefinger and middle finger, for example, about 4 cm.

  The distal end portion 11d of the handle portion 11 is formed in a tapered shape in both the height direction and the thickness direction so as to minimize contact with the front teeth or the like as much as possible during use. The heights of the upper and lower ends of the region (stepped portion) 11e having a predetermined length than the tip end portion 11d are made lower to form stepped portions in the handle portion 11. The cap 3 is inserted until the constricted part 3a contacts the rear end of the step part 11e.

  A first shaft portion 12 is formed so as to be connected to the handle portion 11. Assuming that an axis extending through the central axis of the handle 11 and extending in the longitudinal direction of the handle 11 is a reference line L, the first shaft 12 has an axis center on the reference line L, and the outer diameter increases toward the tip. It is formed in a tapered shaft shape that gradually decreases.

  A second shaft portion 13 is formed so as to be connected to the first shaft portion 12. The second shaft portion 13 is bent at an angle θ1 counterclockwise with respect to the reference line L.

  A third shaft portion 14 is formed continuously with the second shaft portion 13. The third shaft portion 14 is bent at an angle θ2 counterclockwise with respect to the reference line L.

  A periodontal cleaning portion 15 is formed so as to be connected to the third shaft portion 14. The periodontal cleaning unit 15 is bent with respect to the reference line L at an angle θ3 in the clockwise direction. The lower end of the periodontal cleaning part 15 extends between the reference line L and the lower end of the handle part 11.

  The periodontal cleaning unit 15 includes a cleaning unit main body 16 that is a first spatula unit such as a spatula having a thin plate structure in which the plane has a substantially rectangular flat plate shape and a thin plate thickness (for example, 0.5 mm to 0.6 mm). Have. The cleaning portion main body 16 has sharp edge portions 16d at the tip end 16a and both side surfaces 16b and 16c in the width direction. The edge portion 16d is formed by providing inclined surfaces 16e and 16f above and below in the thickness direction. The edge portion 16d is used to remove plaque. In addition, the cleaning part main body 16 makes the corner | angular part R process so that the inside of an oral cavity may not be damaged, and the periodontal can be cleaned safely.

  The cleaning unit main body 16 has a substantially rectangular planar recess 16h formed on the back surface 16g facing the handle 11 side. The recess 16h has a shallow depth and is rounded at a corner. The periodontal cleaning tool 10 is used by putting the cleaning unit body 16 against the back side of the teeth when cleaning the back side of the teeth. At that time, the removed leftovers and plaque accumulate in the depressions 16h. The recess 16h is shallow and has no sharp corners. For this reason, at the time of cleaning after use, the dent 16h is washed with water without using a brush or the like, or is simply wiped off with tissue paper. In addition, about 0.1 mm can be illustrated as the depth of the hollow 16h.

  The cleaning unit main body 16 is thin and long. For this reason, if a large bending force acts on the cleaning unit main body 16 during periodontal cleaning, the cleaning unit main body 16 and the distal end of the third shaft portion 14 are likely to be broken. Therefore, the reinforcing portion 16i having a rounded shape is provided at the continuous place so that the skirt of the reinforcing portion 16i is gradually expanded downward. Therefore, even if a large bending force is applied to the cleaning unit main body 16, the cleaning unit main body 16 can be prevented from being bent on the side connected to the third shaft portion 14.

  The shaft body composed of the first shaft portion 12, the second shaft portion 13, and the third shaft portion 14 is arranged on the reference line L in a straight line from the handle portion 11, as shown in FIG. Further, the second shaft portion 13 and the third shaft portion 14 are bent and arranged above the reference line L, and the periodontal cleaning portion 15 is bent to a position exceeding the reference line L. For this reason, a rough arch shape is formed from the second shaft portion 13 by the periodontal cleaning portion 15, and the periodontal cleaning portion 15 can be positioned on the back side of the tooth beyond the dentition in the oral cavity.

  The periodontal cleaning unit 15 is used to remove plaque, leftovers, etc. by shaking the cleaning unit body 16 in the vertical and horizontal directions. Since the space between the second shaft portion 13 and the periodontal cleaning portion 15 is generally arched, the cleaning portion main body 16 can be moved by grasping the handle portion 11 with a finger without being interrupted by the teeth.

  In this embodiment, the length in the reference line L direction of the first shaft portion 12, the second shaft portion 13, the third shaft portion 14, and the periodontal cleaning portion 15 is, for example, 7 mm, 5 mm, 18 mm, and 4 mm, and the angle For example, θ1 to θ3 are set to 154 °, 175 °, and 120 °.

  In the periodontal cleaning tool 10 of the present embodiment, the periodontal cleaning part 15 is constituted by a cleaning part main body 16 such as a spatula, and therefore, the edge part 16d on both sides of the cleaning part main body 16 and the edge part 16d at the tip end. Can be applied to the front and back of the teeth to remove plaque, leftovers, etc. At this time, the first shaft portion 12 to the third shaft portion 14 and the periodontal cleaning portion 15 are formed of engineering plastic, and the approximate arch shape is formed from the second shaft portion 13 by the periodontal cleaning portion 15. A moderate bending stress acts on the cleaning unit main body 16. Therefore, it is possible to reliably remove plaque and the like by the cleaning unit main body 16.

  In addition, since the first shaft portion 12 to the third shaft portion 14 and the periodontal cleaning portion 15 are formed of engineering plastic, they are durable and can be used repeatedly, and can be used safely and safely without injury. There is good fit to the living body, and cleaning after use becomes easy.

Next, the structure of the interdental cleaning tool 30 will be described in detail.

  The interdental cleaning tool 30 includes a handle portion 31 that is a second handle portion, a support portion 32, and an interdental cleaning portion 33, and is configured by integral molding using engineering plastic (engineering plastic). The handle portion 31, the support portion 32, and the interdental cleaning portion 33 are arranged on the reference line L in a straight line. The interdental cleaning tool 30 has the same overall length as the periodontal cleaning tool 10.

  The handle portion 31 is formed in the same manner as the handle portion 11 of the periodontal cleaning tool 10 and is picked up with a finger with the same feel. Therefore, the same elements as those of the pattern portion 11 shown in FIG. The cap 4 is inserted until the constricted portion 4a contacts the rear end of the step portion 31e.

  The support portion 32 is connected to the tip end of the tip portion 31 d of the handle portion 31. As shown in FIG. 3A, the support portion 32 is formed in a tapered shape whose height in the vertical direction becomes narrower toward the tip. Further, as shown in FIG. 3B, the support portion 32 is formed in a tapered shape in which the thickness in the width direction becomes smaller toward the tip. For example, the support portion 32 may have a base end height of 4.0 mm, a plate thickness of 1.0 mm, a tip end height of 2.0 mm, a plate thickness of 0.3 mm, and a length of 30 mm. That is, the support portion 32 is formed in a thin plate shape and has an elastic force like a leaf spring.

  The interdental cleaning part 33 is connected to the tip of the support part 32. The interdental cleaning part 33 is formed in a substantially rectangular flat plate shape in which the cleaning part main body 34 which is the second spatula part is thin, the height and the plate thickness are constant, the height is 2.0 mm, the plate A thickness of 0.3 mm and a length of 5 mm can be exemplified.

  The cleaning unit main body 34 is formed of a thin plate like the supporting unit 32 provided continuously, and is configured like a spatula formed in a rectangular flat plate shape. For this reason, like the support part 32, it has elastic force like a leaf | plate spring, and it fits between teeth and is inserted.

  As shown in FIG. 3C, concave portions 35, 36, and 37 are formed at the tip and upper and lower side ends of the cleaning unit main body 34. Further, arc-shaped convex portions 38 and 39 are formed at the corners of the tip of the cleaning unit main body 34.

  When inserting the cleaning part main body 34 between teeth, since the convex parts 38 and 39 are circular arc shape, a tooth | gear surface and a gum are not damaged. Moreover, since the cleaning part main body 34 is inserted at a height of 2.0 mm between teeth, for example, cleaning between teeth can be performed easily. In the toothpick with a sharp tip, the interdental cleaning is performed with a point, so that the insertion is repeated many times, and the tooth surface and the gingiva are easily damaged. However, the interdental cleaning tool 30 of the present embodiment can perform interdental cleaning without being repeatedly inserted between the teeth because the cleaning portion main body 34 is inserted between the teeth with a line instead of a point.

  When the cleaning unit main body 34 is inserted between the teeth, the left uneaten food sandwiched between the teeth is inserted into the recess 35 at the tip, and plaque enters. In addition, leftover food between teeth also enters the recesses 36 and 37 on both the upper and lower sides. The inner ends of the recesses 35, 36, and 37 are formed in an R shape, which makes it easy to leave accumulated food, wash away plaque, and wipe off.
