DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG.
The toothbrush, the toothbrush 1 neck 3 at the tip of the handle 2
The brush head 4 is formed integrally with the brush head 4. The brush head 4 is formed of a horizontally elongated thin portion having a long axis in a handle direction in a plan view, and has a large number of flocks 6 on its surface. The basic configuration such as the point where the hair is planted is generally common to a conventionally known toothbrush.

In the toothbrush of this embodiment, as shown in FIG. 1 (A), the brush head 4 has a substantially rectangular shape which is horizontally long in a plan view, and the surface thereof has a horizontally long hexagonal pitch along the outer peripheral contour line. A total of 12 points (filled points in each figure in FIG. 2) at each corner (vertex) of the circle and an intermediate position between the vertices, and 3 points arranged in the longitudinal direction at the center, for a total of 15 points The flocks 6 are arranged at symmetrical positions in the left and right and up and down directions. The pitch circles in the above arrangement form a substantially square shape at the center, and have a substantially equilateral triangular pitch circle on the front and rear sides.

Each of the flocks 6 has a diameter of 0.2 to 0.4.
It is composed of a bundle of several tens of synthetic resin threads made of nylon and the like having a certain elasticity and a waist having a protrusion length of about 13.0 to 14.5 mm in mm. In the above configuration, the brush head 4 has a front end or a rear end as a vertex on the distal end side and the proximal end side, and is planted at a vertex position of a V-shape or a substantially equilateral triangle. All form one point of a triangle or an isosceles triangle. In the case of the simplest arrangement, it is also possible to use only three points at the tip position of the brush head 4.

2 (A) to 2 (F) show other embodiments of the arrangement pattern of the planted strains 6. In each case, the pitch circle shape and arrangement position on the outer periphery and the number of twelve strains are indicated by solid dots. 1A. In FIG. 1A, one flocking plant is arranged between three points of the front end and the rear end to arrange 17 points, and in FIG. 1B, the center in the pitch circle is arranged. In each square, 18 points are arranged by arranging three sets of flocked strains each in two rows on the left and right.

Similarly, in (C), in addition to the one shown in FIG. 1, nineteen points are arranged around the center point in the center square at the diagonal intermediate point. In addition to the one in C), one flocked plant is disposed at the center in the triangle at the front and rear ends to give 21 points. Further, FIG.
Are arranged at 24 or 26 points within the central square portion or at the center of the front and rear ends thereof.

The brushing by the toothbrush 1 configured as described above is effectively performed by a short reciprocating method in which the reciprocating stroke is shortened and the reciprocating is performed. It is desirable to make a short backward movement along the direction or in the direction intersecting the dentition.

FIGS. 3A to 3C and FIGS. 4D to 4F.
Shows a specific example when brushing is performed with the toothbrush 1 of FIG. 1 described above, and arrows indicate the reciprocating direction of the toothbrush. FIG. 3A is a view of the right side of the inner surface of the upper jaw (lingual side).
(B) is the maxillary outer surface (buccal) right, FIG. 3 (C) is the upper outer surface (labial) front, FIG. 4 (D) is lower jaw outer surface front side (lip
Side), 4 (E) is lower jaw inner surface front side (lingual), 4
(F) shows the brushing state of the inner surface of the lower jaw and the right side (buccal side) of the occlusal surface, respectively.

As can be seen in the brushing state shown in the above figure, the density of the flocks 6 and the area of the bristle tip are small with respect to the dentition, but there is little interference between adjacent flocks during brushing, and conversely, between teeth and the tooth surface. The contact between the rugged portion, the gingival portion and the boundary line between the gingiva and the teeth is sufficiently and flexibly performed, so that not only the unpolished portion hardly occurs, but also the massage effect on the gingival portion, particularly the interdental papillae, is large, and No damage to the periphery. These features are particularly significant due to the three or four flocked strains at the distal or proximal end of the brush head. In addition, since the three points are always curved freely and come in contact with the irregularities of the teeth and gums, sufficient brushing can be performed even on the inner surface of the teeth and the posterior teeth (molars), and the operability is good. Very little feeling of vomit.

It should be noted that FIG. 2A to FIG.
In the case of (F), the density of the flocks at the center of the brush head surface is high, but as long as the three-point arrangement at the tip is ensured, the density at the center depends on age, tooth shape, tooth alignment, etc. Can be selected according to individual differences.

FIGS. 6 and 7 show an embodiment of a thread brush according to the present invention. In this embodiment, the size and shape of the brush are substantially the same as those of the end of a commonly used toothbrush. (They may be used for the toothbrush, or may be subjected to necessary processing on the handle of the toothbrush.) A rod-shaped thread holder 11 and a conventionally known thread brush (floss) 12 are provided.

The tip of the thread holder 11 has a locking groove 13 in the shape of a cross or a cut only in the vertical or horizontal direction.
Is formed at a predetermined depth, and one end of the thread brush 12 is inserted and held in the locking groove 13 as shown in the figure, and the thread brush 12 is wound around the outer periphery of the holder 11 as shown in the figure. Is locked at one end. Further, on the outer periphery of the end portion of the thread holder 11, a large number of stripe-like or dot-like uneven patterns are formed so as to prevent the thread brush 12 locked from slipping.

The flossing (tooth brushing) using the thread brush 12 and the thread holder 11 locked as described above is shown in FIG.
As shown in FIG. 8, at least one end (or both ends) of the thread brush 12 is engaged with the thread holder 11, and the other end is gripped with a finger to hold the thread brush 12 between the teeth or between the teeth and the gum. To
It is performed from inside and outside of the dentition. At this time, the thread holder 11
Is gripped by hand as shown in FIGS. 7 and 8, and the distal end thereof is inserted into the oral cavity or moved backward outside the oral cavity.
Is swung along the tooth surface.

By using the thread brush as described above, the degree of freedom of the thread operation is increased as compared with the case shown in FIG.
Since the yarn end can be inserted deeply into the oral cavity and the degree of freedom in the operation of the yarn in the oral cavity is increased, there is an advantage that the range and accuracy of flossing are increased and the efficiency is improved.

[0021]

According to the toothbrush of the present invention configured as described above, a combination of a thread brush and a brush holder is required.
In addition to the brush, the operability of the thread brush improves,
One end of the thread brush can be inserted deep into the mouth
For easy flossing of teeth, gingiva and periodontal
In addition to reliable operation, it can be performed by holding both ends of the thread with fingers.
In comparison, flossing is performed with a light operating force,
Easy losing and prevention of damage to the cervix, etc.
