Description

The present invention relates to a toothbrush that can efficiently polish and remove stains on tooth surface irregularities, food debris, plaque, and orthodontic appliances adhering between teeth or between teeth and gums.

A conventional toothbrush is a brush fixed to a plate-shaped brush base so as to stand up in the vertical direction, and generally has a flat tip portion. In such a general toothbrush, cleaning can be performed only at a portion where the tip portion of the brush abuts vertically. Therefore, there has been proposed a toothbrush that stands up vertically on a plate-shaped flocking table but has irregularities at the tip portion by changing the length of each brush or a part of the tip portion is inclined (for example, Patent Document 1).

Special table 2004-528504

However, in the case of the toothbrush 11 in which all the flocking 41 is fixed so as to extend vertically from the flat flocking table 21, as shown in FIG. 8 in general including the toothbrush of the above-mentioned conventional technique, the drawing is shown in FIG. As shown in 9, since many bristles 51 hit the uneven surface a on the upper surface of the tooth A in the direction perpendicular to each other, there is a problem that the force applied to the bristles 51 is dispersed and the teeth A cannot be sufficiently polished. Further, as shown in FIG. 10, when brushing between the tooth A and the gingiva B, the hair tip 51 also hits the side surface of the tooth A and the gingiva B, and the brushing force is dispersed, so that the hair cannot be sufficiently brushed. There is. Furthermore, as shown in FIG. 11, when the inside and outside of the tooth A are brushed in the direction of the arrow X along the tooth alignment C, some of the flocked 41 are between the teeth A, but many of the flocked 41 Since it bends and enters between the teeth A, there is a problem that the force applied to the hair tips 51 is dispersed and is not applied evenly or unpolished residue occurs.

The toothbrush of the present invention has been made in view of the above circumstances, and the means thereof is a flocking table in which a large number of flocked hairs are planted and fixed, and a hand grip portion integrally fixed to the flocked table. In the toothbrush having the flocking table, the flocking surface for planting and fixing the flocking on the flocking table is a hollow hemispherical recessed arc surface, the lengths of the large number of flocking are uniformly uniform, and the root of the flocking is the inner circumference. Each is fixed in a direction perpendicular to the surface, intersects in a bundle at the intermediate portion of the large number of flocked hairs, and further, the tips of the large number of flocked hairs are opposite to the inner peripheral surface of the hollow hemispherical sphere. It is a mountain-shaped arcuate body . Further, the recessed arc portion is of the same type as a part or all of the inner peripheral surface of the hollow hemisphere. Furthermore, the mountain-shaped arcuate body is isomorphic to a part or all of the outer surface of the hemisphere.

According to the above invention, the flocking surface for planting and fixing the flocking of the flocking table is a recessed arcuate surface, and the intermediate portions of the large number of flocking intersect and the tips of the large number of flocking are chevron-shaped arcuate bodies. Therefore, when the flocking table is put in the oral cavity and brushed, the tip of the chevron arc-shaped body comes into contact with the teeth and brushes, so the tip hits the teeth at right angles from all directions and brushes efficiently. Can be done. Also, it can be polished with a small force. Therefore, it is possible to efficiently polish every corner. Since the middle parts of many flocked hairs intersect, they complement each other and do not bend even when a force is applied.

When the concave arc portion has the same shape as a part or all of the inner peripheral surface of the hollow hemisphere, the intermediate portions of a large number of flocked hairs are twisted and twisted as a bundle at one point, complementing each other and bending. It's difficult. Further, when flocking having the same length is used, a mountain-shaped arcuate body having a shape opposite to that of the recessed arcuate portion is formed at the tip portion, so that the production and molding process are easy. Moreover, even during bushing, a force from a direction perpendicular to the teeth is likely to be applied, so that the teeth can be brushed cleanly.

If the mountain-shaped arcuate body has the same shape as the outer surface of the hemisphere, it can be polished efficiently and cleanly with less operation and as described above.

An embodiment of the toothbrush of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 3, the toothbrush 1 aligns the tip 5 of the flocking 4 which is fixed by planting a large number of flocking surfaces 3 in the direction perpendicular to the flocking surface 3 on the flocking surface 3 of the arc-shaped flocking table 2 so as to form an arc shape. It is made up of. In the toothbrush 1, a long and thin hand grip portion 6 is fixed to the flocking table 2, and the flocking table 2 is put into the oral cavity by grasping the hand grip portion 6 and the tip portion 5 of the flocking 4 brushes the teeth. be.

The flocking table 2 has an arcuate concave arc portion 7 on one surface side and a three-dimensional shape having a smooth surface shape so that it can move in the oral cavity on the other surface side, and a hand grip portion on one end side. 6 is fixed. The recessed arc portion 7 is formed with recesses such as a bowl type, a mortar type, and a hemispherical shape, and a large number of flocked 4 are fixed to the flocked surface 3 of the recessed arc portion 7, and the brush 8 as a whole Is forming.

The flocked 4 is an elongated linear member made of synthetic resin or the like, and its root is fixed to the flocked surface 3 of the recessed arc portion 7 with an appropriate gap. As shown in FIG. 2, this fixing is integrally molded even by adhesion as long as it is fixed in the direction perpendicular to the flocked surface 3 from the flocked surface 3 of the recessed arc portion 7. May be good. In the embodiment shown in FIG. 2, the root portion of the flocked 4 is inserted into the fixing hole 9 dug perpendicularly to the flocked surface 3 and fixed with an adhesive or the like. Since the flocked surface 3 of the recessed arc portion 7 has an arc shape, perpendicular to the flocked surface 3 means perpendicular to the tangential direction passing through the center of the fixing hole 9. The tip portion 5 from the middle portion of the flocked hair 4 fixed in this way changes depending on the surface shape of the flocked surface 3 of the recessed arc portion 7, but the middle portion of each flocked hair 4 is in contact with each other and twisted in a bundle. The polished surface 10 formed by the aggregate of the tip portions 5 forms a chevron arc portion opposite to the flocked surface 3 of the recessed arc portion 7. The shape of the reverse mountain-shaped arc portion varies depending on the shape of the flocked surface 3, the length of the flocked 4, or the cutting method with a cutter.

FIG. 1 shows the case where the recessed arc portion 7 is a semicircular inner peripheral surface obtained by cutting a hollow circular sphere of a ball-shaped sphere at a surface passing through the center thereof, and the lengths of the flocked 4 are the same. As shown in FIG. 3, the central portion of each flocking 4 is twisted and brought into a bundle at the center of the opening circle corresponding to the center of the semicircle, and the polished surface 10 of the tip portion 5 of the flocking 4 is shown in FIG. As is well shown in FIG. 4, it becomes an inverted hemisphere. Since these tip portions 5 extend from the flocked surface 3 of the recessed arc portion 7 in the direction perpendicular to the flocked surface 3, a strong force acts on the flocked surface 5 and the tip portion 5 is radial. Even if it penetrates into the surface a of the tooth A that hits the polished surface 10 and the space between the teeth (see FIG. 5) or between the tooth A and the gingiva B (see FIGS. 4 and 6) and hits with a small force with a small movement. You can polish it evenly.

In the above embodiment, the case where the flocking table 2 of the recessed arc portion 7 is the inner peripheral surface of the hollow semicircular sphere has been described, but the depth of the dent does not pass through a shallower surface, that is, the center of the hollow sphere. It may be a recessed arc portion 7 cut by a surface. In this case, the intermediate portion of each flocked 4 is twisted and intersected in a bundle on the outside of the recessed arc portion 7, and the polished surface 10 formed by the tip portion 5 has a diameter smaller than that of the inverted semicircular sphere. The flocking table 2 itself becomes smaller, and therefore the entire toothbrush 1 also becomes smaller.

The flocking 4 is not planted or fixed in the direction perpendicular to the flocking surface 3 of the recessed arc portion 7, and may have a predetermined angle according to the shape of the recessed arc portion 7. The polished surface 10 of the tip portion 5 may be cut and aligned with a cutter so as to form a mountain-shaped arc portion.

When the tooth A is brushed using the toothbrush 1 of the present invention having the above-described configuration, the aggregate at the tip of the hair implant 3 is a hemispherical sphere. When the hair-implanting table 2 is moved along the tooth alignment C by applying a force in the tooth direction, the hemispherical tip of the polished surface 10 hits the uneven surface of the top surface a of the tooth A from various directions and is polished to eat. Remove the debris. Further, when it enters between the teeth A, it can be brushed from various directions in the same manner. Similarly, the food residue and plaque that have entered between the teeth A can be brushed off by moving brushing.

It is possible to diversify the toothbrush and revitalize the toothbrush industry.
