Description

A tapering-type toothbrush combined with hairs crossly and manufacturing method of it}

The present invention relates to a toothbrush and a method of manufacturing the same, and more particularly, to a toothbrush and a method of manufacturing the seeded so that a group of tapered toothbrushes that have been planted long to one side cross each other.

Conventional toothbrushes are generally planted one group at a small circular hole formed in the head of the toothbrush as shown in FIG. However, these toothbrushes are inferior in productivity and brushing effect and are not beautiful in appearance. Recently, toothbrushes planted one by one in a long rectangular hole as shown in FIG. 2 (hereinafter, referred to as "prior art") have appeared.

The advantage of such a toothbrush is that the number of bristles are planted in one hole, so that the productivity and brushing effect is not only good, but also the appearance is neat and tidy and is favored by consumers. However, there is a problem in that conventional toothbrush can not manufacture this type of toothbrush. The reason is that the conventional method of manufacturing a toothbrush is to insert the bristles in a small circular hole (about 1.6 mm in diameter), and then fix the bristles to the toothbrush with one support pin. It is not possible to manufacture toothbrushes of the prior art with much larger hole sizes.

The toothbrush of the prior art is manufactured by a process of attaching the bristles to the toothbrush by melting the lower part of the bristles by using ultrasonic waves, lasers, heat treatments, etc., after the bristles are inserted into the holes, and a problem of costly manufacturing is required. There is this.

In addition, the toothbrush of this type is the shape of each group of brushed bristles as shown in Figure 2 in the form of a long vertical line because the ability to remove the food debris attached between the teeth in brushing has a bad effect on dental health. There is a problem.

To explain this in more detail, food debris is also attached to the surface of the tooth but is sandwiched a lot between the teeth. In fact, bad breath or tooth decay or tooth decay is mainly caused by food debris between the teeth.

However, brushing is the right way to up and down, and when brushing in this way, the toothbrush shown in Figure 2 is a long form of longitudinal bristle of each group of the planted group, so it is difficult to penetrate into the narrow space between the teeth It is difficult to configure. In addition, when the toothbrush is not correctly used in the up and down direction using the toothbrush as described in FIG. 2, and the brushing is performed for a long time from side to side, the problem is more serious, and the enamel of the tooth surface is damaged, and a horizontal line is easily formed on the tooth surface. The reason is that the bristles of each group that have been planted are all vertically arranged so that the cleaning or polishing force in this direction is much stronger.

In addition, the prior art also has a problem that it is fundamentally impossible to plant a needle hair of 35mm or less because we prepare like a weaving machine with a spinning machine by preparing as many as thousands of meters of thread in accordance with the number of holes planted in the toothbrush. have.

In addition, the toothbrush of the prior art does not use a tapered bristle with a sharp tip, so it is impossible to penetrate the bristles not only between the teeth, but also into the periodontal pocket, which is the interface between the teeth and the gums, thereby eliminating tartar or food debris. Has the problem that it is impossible.

The present invention is to solve the above problems, to provide a toothbrush in which a plurality of bristles are implanted in one hole. Another object of the present invention is to provide a method for manufacturing a toothbrush with improved productivity without requiring expensive equipment. Another object of the present invention is to provide a toothbrush in which the bristled bristles are easily penetrated between the teeth. It is a further object of the present invention to provide a toothbrush which does not form a horizontal stripe on the tooth surface even after long term use. It is yet another object of the present invention to provide a toothbrush with bristles easily penetrating into the periodontal pocket.

In the toothbrush of the present invention, a group in which a plurality of longitudinally long tapered bristles 3 are implanted is arranged in the longitudinal direction on the outside of the head 11 of the toothbrush rod 10, and the inner side of the head 11 of the toothbrush rod 10 is vertically arranged. It characterized in that the group in which the plurality of tapered bristle (3) long in the transverse direction is planted is arranged in the transverse direction.

The toothbrush manufacturing method of the present invention forms a plurality of longitudinally long rectangular holes 1 on the outside of the head 11 of the toothbrush stand 10, and a plurality of rectangular holes 1 horizontally on the inside of the head. After forming a tapered bristle 3 into each hole 1 and fixing the bristle 3 with a long support pin 2, cutting the uneven end of the bristle and tapering polishing It features.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

A method of manufacturing a toothbrush in which bristles are planted in a small circular hole as shown in FIG. 1 is very simple and is completed by planting the bristles as shown in FIG. 4 and fixing them with a support pin. Since the toothbrush manufactured as described above has a hole diameter of about 1.6 mm, the length of the brush head protruding to the surface is fixed and commercialized without fixing the support pin and then post-treatment.

The toothbrush of the prior art as shown in FIG. 2 is not fixed with a support pin, but the bristle is attached to the toothbrush rod by ultrasonic, laser, or heat treatment.

In the manufacturing method of the present invention to insert the tapered bristle in the hole similar to the conventional manufacturing method (Fig. 5) in order to utilize the existing equipment to fix the bristles with a fixing pin (Fig. 4). However, since the holes formed in the toothbrush bar is large, a long support pin is required to fix the bristles. When fixing a large amount of bristles to the hole with this long support pin, the length of the fixed bristles is not constant, unlike in the case of the prior art in which the size of the holes is small.

Therefore, after brushing the bristles, a process of constantly cutting the length of the non-uniformly implanted toothbrush is required. In addition, since the tapered end portion is removed during the cutting process, a step of tapering and polishing the end portion is required again.

The shape of the hole is in the longitudinal direction of the outside of the head of the toothbrush rod, the inner side is transverse. The actual process is first planted in one of the longitudinal or transverse directions and then in another.

The proper size of hole is about 3.0-4.5mm in the vertical direction and 1-2mm in the horizontal direction. If the transverse direction is larger than this, it is impossible to effectively penetrate between teeth. Since the size of the hole is about 4 times larger than that of the conventional round hole, productivity can be greatly improved.

The bristles used in the present invention are acicular hairs whose ends are tapered by chemical treatment, and preferred ones are those prepared by Korean Patent No. 261658 by the inventors.

In the toothbrush of the present invention, a group of toothbrushes implanted at upper and lower end portions of the head 11 of the toothbrush rod 10 may be arranged in a vertical direction as shown in FIG. 3, or may be arranged in a horizontal direction as shown in FIG. 6. Even if arranged as shown in Figure 6 it is possible to achieve the desired effect in the present invention because the polishing force is prevented from being concentrated in any one of the horizontal and vertical directions.

In the toothbrush of the present invention as described above, the direction in which the bristles are planted is intersected vertically and horizontally, so that when brushing up and down, foreign matters attached to the tooth surface can be effectively removed. In addition, since the tip of the bristles is needle-like, it is easy to penetrate between the teeth and into the periodontal pocket, thereby facilitating the removal of foreign matter caught in this part. And even if you brush incorrectly in the left and right direction, the surface of the tooth is damaged and horizontal streaks are greatly prevented.

According to the manufacturing method of the present invention, it is possible to manufacture a toothbrush having a large hole size without processing equipment for ultrasound, laser, heat treatment, etc., which are very expensive equipment, and in the prior art, it is possible to plant a needle hair that cannot be planted. The simulated tapered end can now be maintained.
