Abstract

To provide a toothbrush that not only properly brushes back teeth and refreshingly scrapes away cavity-causing bacteria, but also prevents periodontal disease, thereby promoting oral hygiene and health. [Solution] The base of the bristle brush part at the tip A is formed thin, and the shortest tip bristle bundle 1 is planted in a single bundle at the very end, and bristle bundles 2, 3, 4, 5, 6, 7, side rows of bristle bundles 8, 9, 10, 11, 12, 13, and side rows of bristle bundles 14, 15, 16, 17, 18, 19 are planted in three rows across the width of the brush, and multiple rows are arranged toward the handle part B of the toothbrush body C, and the bristle bundles are long from the tip bristle bundle of each bristle bundle row to the rear end, and the side bristle bundles are shorter than the bristle bundles in the center of the width direction.

Description

[Technical Field]

[0001] The present invention relates to the bristles of a toothbrush bristle tuft. [Background technology]

[0002] Conventional toothbrushes are constructed so that the base of the brush and the base of the handle are roughly the same width, but because the bristles are the same length and width from the tip to the back of the brush, when toothpaste is applied to the brush and it is moved around in the mouth, the inside of the mouth becomes fluffy with foam and only a small area around the front teeth is brushed. The front of the especially important molars gets pinched between the cheek muscles, causing the bristles to bend and open, making it difficult to brush properly, and the back of the teeth have long and wide bristles that make it difficult to brush, making it difficult to remove plaque, which causes tooth decay and periodontal disease bacteria to multiply, damaging the gums and progressing to periodontal disease.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-305289 Summary of the Invention [Problem to be solved by the invention]

[0004] The toothbrush tip base is too wide, and the bristles are long and curved, making it difficult to clean the back teeth, gaps between the teeth, and gums. This allows cavity-causing and periodontal disease bacteria to grow, leading to periodontal disease. Furthermore, plaque hardens into tartar. [Means for solving the problem]

[0005] The toothbrush of the present invention is characterized in that it has multiple rows of bristle bundles arranged in the longitudinal direction of the toothbrush, with each row consisting of three bristle bundles arranged in a single row across the width of the toothbrush, and one bristle bundle arranged closer to the most distal end than the row of bristle bundles at the tip, and the bristle bundles are formed long from the tip to the rear end of the tip of the toothbrush, and the bristle bundles at the sides are formed shorter than the bristle bundles in the central part of the width. [Effects of the Invention]

[0006] Brushing with this toothbrush not only thoroughly cleans the back teeth, leaving the mouth feeling refreshed and clean, and scraping away cavity-causing bacteria, but also has far-reaching effects, such as preventing periodontal disease and improving oral hygiene, ultimately improving the health of a wide range of people, from infants and children to adults and the elderly.

[0008] In the toothbrush of this invention, the tip of the bristle base is thin, the bristles at the tip are the shortest, and the length of the bristles in the bristle rows on both sides is cut one step shorter than the central bristle row. The brush is characterized by a form in which the bristles at the tip of the bristles are gradually lengthened in stages diagonally from the tip, where the bristles are the shortest, to the rear end of the brush, where the bristles are the longest.

[0009] Figure 1-1 shows a side view of the toothbrush of the present invention, where tip portion A is the bristle brush portion including the base, and handle portion B is the handle-side base connected to the base of tip portion A. Tip hair bundle 1 and central hair bundles 2, 3, 4, 5, 6, and 7 are the cut central hair bundles. Tip hair bundle 1 at the very front is the shortest, and central hair bundle 7 at the very back is the longest. Outer hair bundles 8, 9, 10, 11, 12, and 13 are hair bundles implanted on the far side of the central hair bundle. Side hair bundles 14, 15, 16, 17, 18, and 19 are hair bundles implanted in front of the central hair bundle. The hair bundles 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, and 19 in the side rows are each cut one step shorter than the central hair bundle row and implanted.

[0010] Figure 1-2 shows a front view of the toothbrush of the present invention, in which the base of the bristle brush part at the tip A is formed thin, and the shortest tip bristle bundle 1 is arranged in a single bundle at the very end, and bristle bundles 2, 3, 4, 5, 6, 7, bristle bundles in the side rows 8, 9, 10, 11, 12, 13, and bristle bundles in the side rows 14, 15, 16, 17, 18, 19 are arranged in three rows across the width of the brush, and multiple rows are arranged toward the handle part B of the toothbrush body C, and the bristle bundles are formed long from the tip bristle bundle to the rear end of each bristle bundle row, and the bristle bundles on the sides are formed shorter than the bristle bundles in the center of the width direction.

[0011] Figure 2-1 shows an enlarged side view of the brush of the present invention. The tip tuft 1, which is planted at the very tip of the tuft base, is the shortest, with the optimum length of the tuft being 2.5mm to 3mm. While you can brush your molars with a blade longer or shorter than this length, it will not be as effective. Tip tuft 1 of the central tuft row and tufts 2, 3, 4, 5, 6, and 7 of the central row are gradually cut and planted diagonally from the length of tip tuft 1, with the optimal length of tuft 7 in the central row at the rear end of the brush being 10 mm. Using this central tuft row as a base, the tuft lengths of tufts 8, 9, 10, 11, 12, and 13 in the side rows on both sides and tufts 14, 15, 16, 17, 18, and 19 in the side rows should each be 1.5 mm shorter, and the best configuration is to plant and cut the tufts in three rows toward the handle B. If the hair is planted wider than this, the inside of the mouth will end up looking fuzzy. The optimal number of hair strands for a tuft is 40-44 strands planted in a V-shape with 80-88 bristles at the tip. An even better shape would be if all the bristles were shaped into a cone.

[0012] Figure 2-2 shows an enlarged front view of the brush part of the present invention. The tip of the brush part is formed to be thin, and from the tip to the handle part B, all bristles are arranged in three rows except for the tip tuft 1 in the central tuft row, and all bristles are also arranged in three rows in the width direction except for the tip tuft 1.

[0013] Figure 2-3 shows an enlarged view of the toothbrush part of this device viewed from the tip, with the bristles planted in stages from the tip bristles 1 of the central bristles row to the longest bristles in the central row 7, and the bristles in the side rows on both sides 8, 9, 10, 11, 12, 13 and the side rows 14, 15, 16, 17, 18, 19 are each cut and planted one step shorter.

[0014] The embodiment of this invention suggests that the most effective results can be achieved by simply making small changes to your toothbrushing habits. For example, hold the toothbrush like a pencil, brush your teeth for 10 minutes at least once a day at night, and brush your teeth slowly and carefully over time. [Explanation of symbols]
