  Embodiments of a toothbrush according to the present invention will be described below with reference to the drawings. In addition, this invention is not limited to the following embodiment, The shape, material, etc. of each component disclosed in embodiment are only a preferable example, and other shape, material, etc. Belongs to the technical scope of the present invention as long as it has a similar action.

  FIG. 1 is a partial side view showing a toothbrush according to an embodiment. FIG. 2 is a side view and a partially enlarged cross-sectional view of a tapered bristle constituting a bristle bundle of a toothbrush according to the embodiment.

  The toothbrush 1 includes a head portion 2, a neck portion 3 extending from the head portion 2, and a handle portion 4 extending from the neck portion 3. The toothbrush 1 is not limited to the configuration in which the head portion 2, the neck portion 3, and the handle portion 4 are integrally formed, and the head portion 2, the neck portion 3, and the handle portion 4 may be detachable. Good.

The head portion 2, the neck portion 3, and the handle portion 4 are formed of, for example, a hard resin material.
Examples of the hard resin material include polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polycyclohexylenedimethylene terephthalate (PCT), polybutylene terephthalate (PBT), polyacetal (POM), and polystyrene (PS). And thermoplastic resin materials such as polyurethane, polyamide, and acrylonitrile / butadiene / styrene resin (ABS), but are not necessarily limited to these materials. The handle portion 4 may be partially or wholly covered with a flexible resin such as an elastomer.

  The handle portion 4 is a portion that is gripped by the user and is formed in a substantially rod shape. The neck portion 3 is a portion that connects the handle portion 4 and the head portion 2, and is formed into a shape constricted from the handle portion 4 toward the head portion 2.

  The head portion 2 is a portion that enters the oral cavity, and may have any shape or size that facilitates cleaning of the oral cavity. For example, the width is preferably about 10 mm to 15 mm and the thickness is about 3 mm to 8 mm. The top surface of the head portion 2 is a flocked surface 2a, and a plurality of flocked holes 2b for planting the hair bundle 5 are arranged in the length direction and the width direction of the head portion 2 on the flocked surface 2a. Thus, for example, it is formed in a lattice shape or a zigzag shape at a predetermined interval. The arrangement and interval of the flock holes 2b, the combination thereof, and the like are not particularly limited, and can be arbitrarily changed in consideration of a feeling of use, a feeling of cleaning, a cleaning effect, durability, and the like.

  A hair bundle 5 is implanted in each flock hole 2b. Tapered hairs 6 are used for each brush constituting the hair bundle 5 as shown in FIG. The taper bristles 6 have a taper portion 6a whose diameter gradually decreases toward the tip. In the present embodiment, the taper hair 6 having the taper portions 6a formed at both ends is folded in two and used. The tapered bristles 6 can improve the hair tip penetration with respect to the interdental portion, gum portion, and the like. Moreover, it is preferable that the ratio of the taper part 6a is the length within 1/3 from the front-end | tip of the taper hair 6. FIG. By setting such a ratio, it is possible to clean the interproximal part and the tooth neck part, and to obtain a good brushing feeling and usability.

  Further, the taper bristles 6 contain bamboo charcoal powder 7 as shown in FIG. Bamboo charcoal powder 7 is obtained by burning and carbonizing (black carbonization or white carbonization) bamboo and pulverizing bamboos such as Miso bamboo, light bamboo, true bamboo, maitake, black bamboo, Kimmingo bamboo bamboo, and cloth bamboo bamboo. For bamboo charcoal powder 7, use low-temperature charcoal (one that has been baked at around 400-600 ° C), medium-temperature charcoal (one that has been baked at 700-1000 ° C), or high-temperature charcoal (one that has been baked at 1000 ° C or higher). However, it is more preferable to use medium temperature charcoal and / or high temperature charcoal. In particular, it is preferable to use medium temperature charcoal in order to enhance the antibacterial and deodorizing effect (adsorption action).

  The particle size of the bamboo charcoal powder 7 is not particularly limited, but the average particle size is 0.001 μm to 10 μm, preferably 0.001 μm to 1 μm or less, more preferably 0.001 μm to 0.01 μm in nano order (nanoparticles). Bamboo charcoal powder 7 is preferably used. In particular, the bamboo charcoal powder 7 preferably contains the nano-order bamboo charcoal particles. The smaller the particle size, the better the familiarity and dispersibility with the resin material constituting the tapered hair 6, and the surface area of the bamboo charcoal powder 7 can be increased. The bamboo charcoal powder 7 may be bamboo charcoal powder for food additives. A part of the bamboo charcoal powder 7 is exposed on the surface of the tapered hair 6. The bamboo charcoal powder 7 has numerous pores, has a deodorizing function that adsorbs odorous substances, etc., and contains silicic acid having antibacterial activity, and suppresses the growth of various germs. It has a function to suppress odor caused by proliferation. Further, the bamboo charcoal powder 7 has a function of generating negative ions, and has a function of enhancing the cleaning effect by neutralizing positively charged oral substances (such as plaque).

  The resin material constituting the tapered hair 6 is not particularly limited. For example, polyamide (eg, 6-12 nylon, 6-10 nylon, etc.), polyester (eg, PET, PBT, polytrimethylene terephthalate (PTT) ), Polyethylene naphthalate (PEN), polybutylene naphthalate (PBN), etc.), polyolefins (eg, polypropylene (PP), etc.), elastomers (eg, olefins, styrenes, etc.), etc. Can do. A plurality of these resin materials may be used in combination. For example, different resin materials (such as polyester) may be used for the core portion and the sheath portion, such as a core-sheath structure (multi-core structure).

  A predetermined amount of bamboo charcoal powder 7 is added to these resin materials and kneaded to form a brush (filament). The amount of bamboo charcoal powder 7 added is not particularly limited as long as the antibacterial and deodorizing effect of bamboo charcoal powder is obtained, but is appropriately set in consideration of characteristics such as the strength and durability of the tapered bristles 6. For example, it is preferable to contain about 0.1 to 10% by weight, preferably about 0.5 to 5% by weight, and more preferably about 0.8 to 1.2% by weight with respect to the resin material. By setting it as the above-mentioned content, it becomes possible to satisfactorily exert the effect of suppressing the germs and the deodorizing effect of the hair bundle 5 and the flock hole 2b due to the antibacterial and deodorizing actions of the bamboo charcoal powder 7, and the bamboo charcoal powder 7 The filaments contained can be molded well.

  Although the manufacturing method of the taper hair 5 is not specifically limited, For example, the brush (filament containing bamboo charcoal powder 7) cut by predetermined length is immersed in a processing agent (for example, alkaline hydrolysis processing agent etc.) and dissolved. Thus, the tapered portions 6a can be formed on both ends of the hair, and a part of the bamboo charcoal powder 7 can be exposed on the surface. Moreover, the length and thickness (thinness) of the taper part 6a of a hair tip can be adjusted by adjusting the length of the hair tip immersed in the said processing agent, processing time, etc. Further, the length and thickness of the tapered portion 6a may be changed between one end and the other end of the tapered hair 6.

  The length of the hair bundle 5 (the taper hair 6 folded in half) is preferably 8 mm to 13 mm for adults and 6 mm to 9 mm for children, for example, from the flocked surface 2 a of the head portion 2. The thickness (maximum diameter) of the tapered bristles 6 is preferably 0.12 mm to 0.26 mm from the viewpoint of usability in the oral cavity. Further, considering the feeling of use, the feeling of brushing, the cleaning effect, the durability, etc., the tapered hairs 6 having different thicknesses are arbitrarily combined, or the thickness of the tapered hairs 6 is changed according to the position of the flocking hole 2b. Also good.

  Moreover, although the cross-sectional shape of the taper bristles 6 is preferably circular, it is not necessarily limited to a circle. Depending on the intended use of the toothbrush 1, for example, an ellipse, a polygon (for example, a triangle, a quadrangle, a pentagon, a hexagon, etc.) and an irregular shape (for example, a star, a three-leaf clover, a four-leaf clover) Any cross-sectional shape can be used. Furthermore, the taper bristles 6 may be spiral or embossed.

  In addition, each hair bundle 5 is usually a bundle of a plurality of tapered hairs 6 bundled in a substantially circular shape, but is not limited to one bundled in a substantially circular shape. For example, it may be bundled in a polygonal shape such as a substantially triangular shape or a substantially quadrangular shape, and may be a bundled shape having a major axis and a minor axis different from each other, such as a substantially elliptical shape, a substantially oval shape, or a substantially rectangular shape.

  Further, the cross-sectional shape of the flock hole 2b is usually circular in accordance with the shape of the hair bundle 5 in which a plurality of the taper hairs 6 are bundled, but is not limited to this, and the taper hairs 6 are bundled. It can be set as an arbitrary shape according to the shape of the hair bundle 5.

  Each hair bundle 5 is formed by bundling a plurality of the above-described taper hairs 6 and folding them into two, and driving them into the flock holes 2b with a retaining tool called a flat wire 8 (see FIG. 2) between them. It is planted in each flock hole 2b. Although it is preferable to make the heights of both ends of the tapered bristle 6 folded in half, it may be folded in a state where the heights of both ends are intentionally shifted. The tapered bristles 6 constituting the bristles 5 are those in which both ends are tapered, and the bristles 5 are not limited to this configuration. In another embodiment, the other end side of a plurality of taper hairs having a taper portion only on one end side may be bundled, and the other end side may be planted in the tuft hole 2b.

  The flat line 8 passes through the center of the flock hole 2b and is placed in the flock hole 2b so as to straddle the flock hole 2b. Examples of the material of the flat wire 8 include metals such as brass and stainless steel, but may also be hard plastic or biodegradable plastic. The flat wire 8 has a shape whose length is larger than the diameter of the flocked hole 2b and whose width is smaller than the depth of the flocked hole 2b. Moreover, what is necessary is just to adjust arbitrarily about the length, the width | variety, and thickness of the flat wire 8 according to the size of the hair | bristle bundle 5 or the flock hole 2b. The method of planting the hair bundle 5 in the flocking hole 2b is not limited to the method of placing the flat wire 8 in the flocking hole 2b, and the flocking hole 2b is formed by heat fusion or the like. You may plant it.

  According to the toothbrush 1 which concerns on the said embodiment, since the bristle bundle | flux 5 is the one which folded and bundled the taper bristle 6 which has the taper part 6a at both ends, the bristle bundle | flux 5 (each taper bristle 6) is bundled. Since the tip is sharpened (tapered) by the tapered portion 6a, the interdental portion and the tooth neck portion can be cleaned well. Moreover, since bamboo charcoal powder 7 is contained in the taper hair 6 in a substantially uniformly dispersed state, the antibacterial effect and deodorizing effect of bamboo charcoal powder 7 can suppress the germs of hair bundle 5 and flock holes 2b and deodorize effect. The toothbrush 1 can be kept in a hygienic state.

  Moreover, according to the toothbrush 1, since the bamboo charcoal powder 7 kneaded into the taper bristles 6 is nanoparticles (particles having a size on the order of nanometers (nm)), the surface area of the bamboo charcoal powder 7 is extremely increased. The antibacterial action and deodorant action of the bamboo charcoal powder 7 can further enhance the antibacterial and deodorant effects of the hair bundle 5 and the flock hole 2b, and the toothbrush 1 can be maintained in a hygienic state for a long period of time. .

  In addition, this invention is applicable not only to what was applied to the said toothbrush 1, but the electrically driven electric toothbrush, its replacement brush, etc. The present invention is not limited to oral brushes such as the toothbrush 1, and can be widely applied to brushes in which a plurality of hair bundles 5 are implanted on the flocked surface 2 a of the head portion 2. is there.
