Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning toothbrush suitable for cleaning interdental areas and smooth surfaces of teeth.

[Prior Art] Generally, as a toothbrush for cleaning the interdental area, a toothbrush in which two bundles of bristles are implanted at an angle so as to support each other in a bristle part is commonly used for rolling brushing.

[Problem that the invention attempts to solve]

This type of toothbrush can deliver the bristles to the interdental area more stably than toothbrushes that have bundled bristles that are cut into chevrons or waves, and they are also more durable. However, since the distance between the peaks formed by the two bundles of bristles is too wide, it is difficult to clean areas other than the interdental area. That is, when the tips of the bristles enter the interdental area due to the inclination of the bristles, the freedom of the bristles is restricted, and the tips of the bristles do not touch the smooth surfaces of the teeth, resulting in a disadvantage that the cleaning effect is low.

[Means for solving problems]

The present invention aims to eliminate the above-mentioned conventional problems and provide a toothbrush that has both interdental cleaning effects and cleaning effects on the smooth surfaces of teeth. In a toothbrush having a flocked part formed by planting a plurality of bristle bundles on the bristle bed, each bundle of bristle is planted at appropriate intervals in the longitudinal direction of the bristle bed and at an angle to the bristle planting surface of the bristle bed. A plurality of first bristle bundles formed in a chevron shape by bringing together the tips of the hairs are provided in the longitudinal direction of the bristle transplanting table, and between two first bristle bundles adjacent to each other in the longitudinal direction of the tufting table. This toothbrush is characterized in that a second bristle part is implanted so that the entire bristles are located in the gap formed.

〔Example〕

An example of the present invention will be described based on the drawings.
As shown in FIG. 1a, two bundles of hair 1 ₁ , 1 ₁ are planted at an appropriate interval in the longitudinal direction of the flocking table 2 and at an angle on the flocking surface 4 of the flocking table 2. As a result, the tips 5 ₁ and 5 ₁ of each of the hair bundles 1 ₁ and 1 ₁ are brought together to form a mountain-shaped hair bundle portion 6 ₁ . The mountain-shaped top portion of the hair bundle portion 6 ₁ is also formed into a mountain shape whose hem follows the longitudinal direction of the hair transplanting table 2 , but a convenient method for forming this is to cut off the tip 5 ₁ of the hair after the hair is transplanted. It is. A plurality of bristle bundle parts 6 ₁ corresponding to the first bristle part 6 1 formed in this way are provided at approximately equal intervals in the longitudinal direction of the tufting table.
so that it is located in the gap between two adjacent bristles 6 ₁ , 6 ₁ (when the flocked part 3 is mounted from the front),
A bundle portion 6 ₂ of flat brushes is provided. This bristle part 6 ₂ , which corresponds to the second bristle part, has the bristle 1 ₂ planted almost perpendicularly to the tufting table 2, and the tips 5 ₂ of the bristle are planted in a plane almost parallel to the tufting surface 4. Although it is finished in a spherical shape, it may be finished in a spherical shape.

FIG. 1b shows the arrangement of the tuft holes for forming the bristle portions 6 ₁ and 6 ₂ , and the tuft holes 7 ₁ marked with white circles have the tufts 1 ₁ planted at an angle. ,
The hair bundles 1 ₂ are vertically planted in the tuft holes 7 ₂ indicated by black circles.

That is, the tufted hair portions 6 ₁ and 6 ₂ are alternately planted in the same row in the longitudinal direction of the bristle transplanting table 2, and a total of four such bristle portion rows are formed.

In addition, as for the shape of the tip of the bristle part ₆₁ , it is preferable that the top part of the chevron is in a flat shape almost parallel to the tufting surface 4 of the tufting table 2, and the tip of the bristle is formed in the shape of the tip of a knife. A chevron-shaped top portion may be formed by a plurality of bundles of hair.

Further, in the example shown in FIG. 1, the hair bundle portion ₆₁ is formed of two hair bundles, but it may be formed of three or more hair bundles. For example, three tuft holes may be placed in the same row in the longitudinal direction of the tuft table, with the central tuft hole planted upright and the other holes slanted, or the three tuft holes placed at each vertex of an equilateral triangle. It is possible to form a chevron shape by installing each bundle of hair at an angle.

Therefore, when the inside of the oral cavity is rolled with a toothbrush having such a bristled part 3, the interdental area is cleaned by the chevron-shaped bristles tips ₅₁ of the chevron-shaped bristles part ₆₁ , and at the same time, the bristles are The bristles 5 ₂ of the bristles 6 ₂ also brush the smooth surfaces of the teeth, significantly improving the cleaning effect.

In this case, it is preferable that the height of the flocked hair (height of the top part) of the hair bundle part 6 ₁ is set higher than or equal to that of the hair bundle part 6 ₂ . Cleaning of smooth surfaces can be performed more evenly.

Next, FIG. 2 shows another embodiment, in which the row of tuft holes in the bristle part 6 ₁ and the row of tuft holes in the bristle part 6 ₂ are made into separate rows (in the example in FIG. Each bristle part is planted on the pore row), and the interval between each bristle part is reduced to further enhance the cleaning effect.

On the other hand, in the example shown in FIG. 3, instead of the flat brushed bristles in the previous embodiment, a bristle having the same shape as the chevron-shaped bristles is implanted. That is,
In this embodiment, a plurality of bristle bundles ₆₁ having the same shape as the example in FIG. A total of two rows of bundled bristle parts ₆₂ are formed by shifting the phase of the rows of bristle parts ₆₁ in the longitudinal direction of the tufting table, and the top of the mountain of the bundled bristle parts ₆₂ , that is, the tip ₅₂ of the hair, is
It is located between the peaks of the bundled hair part ₆₁ .

In this way, the toothbrush in which the flocked portion 3 is formed only of the chevron-shaped bristles has the advantage that, in addition to the above-mentioned cleaning effect, durability is also significantly improved.

In this embodiment, the tips of the hair bundles 6 ₂ can be flat parallel to the flocking surface or spherical, but in any case, the tips of the hair bundles 6 ₁
By making the height of the flocked hair higher than that of the bundled hair portion ₆₂ , the interdental area and the smooth surfaces of the teeth can be cleaned more evenly.

[Effects of the invention] According to the invention, it is possible to provide a toothbrush that not only has the advantage of being able to effectively clean the interdental area and the smooth surfaces of teeth at the same time, but also has excellent durability during use. be.
