【Example】

 An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. 1 to 3 show a plaque control tool according to the present invention, which is composed of a handle portion 10, a floss support portion 20 and a brush portion 30 which are detachable from each other. The handle 10 is a rod having a substantially rectangular cross section and is formed of metal or synthetic resin. An engaging groove 11a, which will be described later, with which the floss support portion 20 engages is formed at one end 11 of the handle portion 10, and a neck portion 12 with which the tooth brushing portion 30 of the tooth brush engages is formed at the other end as a brush portion. Has been done. Then, the handle portion 10 is gradually reduced in the longitudinal direction from the one end portion 11 toward the neck portion 12 in a similar cross-sectional shape, and reaches the neck portion 12 at the connecting portion 12a in the thickness direction and the width direction. The cross-sectional area is being rapidly reduced. The neck portion 12 has a flat plate shape, penetrates from the upper surface 12b to the lower surface 12c, and the through holes 12d, 12d, 12d into which the protrusions 33, 33, 33 of the flocked portion 30 described later are fitted are formed at equal intervals. Has been done.

The bristle-implanting portion 30 is made of a synthetic resin base 30a, which has a substantially flat plate shape, and a large number of brushes 34 made of, for example, nylon, which are planted on the upper surface 31, and the lower surface 32 of the base 30a is provided. A groove 35 having a rectangular cross section extending from one end surface to the other end surface in the longitudinal direction and having substantially the same sectional shape as the neck portion 12 is formed, and the neck portion 12 is fitted into this groove 35. The lower surface 32 of the base 30a near the left end surface in the drawing is cut out in the width direction to avoid interference with the connecting portion 12a when the neck portion 12 is fitted in the groove 35 (A portion in FIG. 1). . From the groove bottom of the groove 35, the above-mentioned three cylindrical projections 33 that fit into the through holes 12d are provided in a protruding manner. When it is inserted into the through hole 12d, the tip bulge portion penetrates through the through hole 12d and projects from the lower surface 12c, so that the bristle portion 30 does not deviate from the neck portion 12.

A cross-shaped groove 11 a is bored at a predetermined depth from one end 11 of the handle portion 10 toward the neck 12 from the end surface of the end surface divided into four surfaces by the cross groove 11 a. In each divided surface 11b, each end edge in contact with the vertical groove of the cross groove 11a extends obliquely straight from the center of the groove 11a toward the outer side, and is opposite to the neck portion 12, and each side edge in contact with the lateral groove of the cross groove 11a is formed. The groove 11a extends obliquely straight from the center of the groove 11a toward the neck 12 side, and is formed in an inclined plane including the edge and the side edge.

The floss support portion 20 is composed of a forked portion 20a bifurcated into two fingers 21 and 22 and a straight portion 20b. The straight portion 20b is provided at the end opposite to the forked portion 20a. A wedge 23 having a cross-shaped cross section which is aligned with and fits in the cross groove 11a of the handle 10 is formed, and the base of the wedge 23 has an inclined surface 23a facing and facing the dividing surface 11b. Has been formed. On the rear surface 25 of the end portion of the straight portion 20b on the side of the bifurcated portion 20a, a mushroom-shaped projection 23 is provided at the center thereof. On the other hand, the fingers 21 and 22 of the bifurcated portion 20a are slightly bent in the vicinity of the tip thereof on the side opposite to the protrusion 23 (the ventral surface side of the straight portion 20b), and the fingertips are laterally cut. The locking grooves 21a and 22a are formed so that the floss 50 described later does not deviate.

The floss 50 has a large ring portion 50a and a small ring portion 50b formed by binding dental floss of a predetermined length. When the plaque control device constructed as described above is used, the protrusions 33, 33, 33 of the hair transplant part 30 are fitted into the through holes 12d, 12d, 12d of the neck 12, and as shown in FIG. The hair-implanted portion 30 is locked and fixed to the neck portion 12 and used as a toothbrush. As shown in FIG. 3, the normal floss support portion 20 is used by integrating the wedge 23 with the cross groove 11a so as to be integrated with the handle 10.

Next, when plaque control is to be performed using the floss 50, a fingertip is put into the small ring portion 50b of the floss 50 and a part of the large ring portion 50a is inserted into the locking grooves 21a and 22a. The small ring portion 50b is pulled toward the protrusion 24 in a state of being locked and stretched between the fingers 21 and 22 of the floss support portion 20, and the vicinity of the knot between the small ring portion 50b and the large ring portion 50a is fixed to the protrusion 24. Hang up. At this time, since the bifurcated portion 20a is formed of an elastic member, the large ring portion 50a of the floss 50 is stretched between the fingers 21 and 22 of the bifurcated portion 20a by the elastic force of the bifurcated portion 20a. This facilitates the handling of the floss 50 and pushes the floss 50 between the teeth to effectively remove plaque (plaque).

The floss support portion 20 may be detached from the handle portion 10 and used, if necessary. Further, instead of the floss shown in FIG. 1, knot balls 55a, 55a are formed at both ends as shown in FIG. 3, and the small ring portion 56 is connected to and formed on one of the knot balls 55a. Alternatively, the straight line floss 55 may be used under tension, and in this case, the length between the knot balls 55a and 55a is slightly shorter than the fingertip distance between the fingers 21 and 22 of the forked portion 20a. Put a fingertip into the small ring portion 56 of the floss 55, and in a state where the knot ball 55a on the tip side is fitted and locked in one of the locking grooves 22a (21a), the small ring portion 56 is locked in the other locking groove. 21a (22a) side, the forked portion 20a is bent, and the knot ball 55a on the small ring portion 56 side is locked in the locking groove 21a (22a). Also in this case, the floss 55 is stretched between the fingers 21 and 22 while being tense by the elastic force of the forked portion 20a.

FIGS. 4 and 5 show a mode in which an interdental small brush 60 is attached to the neck portion 12 of the handle 10 instead of attaching the toothbrush bristle portion 30 as a brush portion. The small interdental brush 60 has a brush support piece 61 having a substantially truncated cone shape, and a large number of brushes horizontally implanted on a stranded wire protruding from the center of the upper end surface of the brush support piece 61 having a small diameter, and shaped into a tree shape. And a projection 63 having the same shape as the projection 33 of the bristle-implanting portion 30 of the toothbrush, which protrudes downward from the large-diameter lower end surface of the brush support piece 61. It The small interdental brush 60 is used by fitting it into any one of the three through holes 12d of the neck 12, preferably into the through hole 12d formed on the most distal side (see FIG. 5). . Plaque control is even more effective when the interdental small brush 60 is used in conjunction with the toothbrush bristles 30 and floss 50 (55). The small interdental brush 60 may be attached to an auxiliary handle 65 prepared separately, and the auxiliary handle 65 is formed of plastic or metal. As shown in FIG. 4, the lower handle 65a grips the auxiliary handle 65. It is a substantially cylindrical rod body that bulges like a teardrop for the sake of convenience, and a bottomed hole 66 into which the projection 63 is fitted is formed in the center of the upper end surface of the rod body. The bottom of the hole 66 is spherically bulged so as to match the shape of the tip of the protrusion 63 that is spherically bulged. When the protrusion 63 is fitted into the hole 66, the interdental small brush 60 deviates indiscriminately. I'm trying not to.

In the above-described embodiment, the handle portion 10, the brush portion 30, and the floss support portion 20 are detachable from each other, but all or a part of them may be integrally molded, and the handle portion 10 and The floss support portion 20 is wedge-joined with the cross-shaped groove 11a and the wedge 23. However, the present invention is not limited to this, and various other methods are conceivable as the joining method. A female screw and a male screw may be formed on each of the connection ends of the floss support portion 20 and the floss support portion 20 to be screwed together.

Further, the bristle implanting portion 30 and the interdental small brush 60 of the toothbrush are adapted to be fitted into the through holes 12d by the projections 33 and 63. A hole for fitting the projection may be provided on the brush 60 side. Further, in the above-described embodiment, the brush portion 30 of the toothbrush and the small interdental brush 60 have been described as examples of the removable brush portion, but other special brushes such as a known rubber tip may be used.
