Toothbrush head {TOOTHBRUSH HEAD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toothbrush head, and more particularly, to a toothbrush head capable of effectively removing plaque between the teeth and teeth and easily wiping the back of the molar which is difficult to reach by the toothbrush.

In general, a plaque is a sticky, transparent film that sticks to the surface of a tooth, also called a plaque. Plaques are made up of many germs (bacteria) living in the mouth clinging to certain components in saliva, and also in teeth, prostheses, orthodontic appliances, dentures and their surroundings.

The bacteria in the plaque not only damage the gums by creating toxins and free oxygen, but also damage the teeth and surrounding tissues. When the teeth and gums are damaged, they become swollen, bloody, and bad breath. In particular, plaque accumulation in the periodontal pouch caused by the gap between the teeth and gums damages the bone supporting the tooth, and in the worst case, the tooth is lost.

Therefore, it is necessary to remove plaque by usual brushing. In order to effectively remove plaque, it is necessary to remove all of the plaque (tooth surface, tooth surface), tooth (between cervical tooth and gum), interdental (between tooth and tooth) The bristles must reach the area.

However, since conventional bristles are uniformly formed of a bundle of bristles having a round cylindrical structure or a bundle of bristles has a uniform arrangement pattern, the tooth cleaning ability is excellent, but the plaque cleansing force and the interdental penetration force are poor and the plaque can not be effectively removed.

To solve this problem, a brush bristle bristle structure of a toothbrush having a triangular bristle bundle and a rhombic bristle bundle has been proposed (Korean Utility Model Registration No. 20-0306545 (Feb. 25, 2003)). However, such a conventional bristle bristle brushing structure, And it was not suitable for general use.

Accordingly, there is a need for a design of an appropriate bristle shape and arrangement that can effectively remove plaque from the teeth and teeth, even if brushing is performed in various ways.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1, the toothbrush 1 includes a handle 100 that is elongated in one direction and a head 200 that is integrally formed on the tip of the handle 100. The handle 100 includes a head 200, The handle 100 is a portion held by the user, and the head 200 is a portion where the bristles 300 are worn.

The handle 100 and the head 200 may be formed of a material selected from the group consisting of polypropylene, polyethylene, polyethylene terephthalate, polycyclohexylenedimethylene terephthalate, saturated polyester resin, polymethylmethacrylate, cellulose propionate, polyurethane, Acrylonitrile, butadiene, styrene), and the like. Further, the handle 100 may be partially or wholly applied with a flexible resin such as an elastomer in order to improve gripping property and prevent slippage.

The bristles 300 are comprised of a plurality of tufts 310 to 350 that are worn on the wicking surface 210 of the head 200. The bundles of filaments 310 to 350 are bundles of filaments and are folded into a U-shape. A fixing member (not shown) is sandwiched therebetween. do. The filaments 310 to 350 may be bundled into a shape such as a polygon, an ellipse, or a rectangle such as a triangle or a quadrangle. Also, in this embodiment, it is exemplified that the bundle bundles 310 to 350 are fixed by using a fixing piece, but it goes without saying that it can be fixed by a heat fusion bonding method.

The material of the bristles 300 may be selected from the group consisting of polyamides (6-12 nylon, 6-10 nylon), polyesters (polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate), polyolefins (polypropylene) Olefin-based, and styrene-based), and the like.

The filament constituting the bristles 300 may have a polygonal cross section including a circle or a triangle, and the ends may be hemispherical or tapered.

Referring to FIGS. 1 to 3, a bristle 300 implanted in a toothbrush head according to an embodiment of the present invention will be described.

The bristles 300 include a first tuft 310 for cleaning the rear side of the molar teeth that is difficult for the toothbrush to reach, a second tuft 320 for cleaning the rear side of the front teeth and the canines, Three tufts 330 and fourth and fifth tufts 340 and 350 for effectively removing plaque between the teeth and teeth.

The first through fifth mold bundles 310 through 350 of the present embodiment are formed of a plurality of unit mold bundles (one mold bundle block), and the unit modulars are arranged to have a constant pattern to have the above-described functions. That is, the first mold bundles 310 are arranged to form a semicircular pattern and the second mold bundles 310 are arranged to form a V-shaped pattern. The third pattern 330 is arranged to form an X-shaped pattern, and the fourth pattern 340 is disposed between the third pattern 330. In addition, the fifth hair bundles 350 are arranged to form an arc pattern.

In addition, the first to fifth hair bundles 310 to 350 of the present embodiment have the following area ratios. The areas of the first and second pattern bundles 310 and 320 are 1 to 2 and the area of the third pattern 330 is 1 to 2 when the area of the fourth and fifth pattern bundles 340 and 350 is 1 .

That is, the fourth and fifth bundles 340 and 350: the first and second bundles 310 and 320 = 1: 1 to 2

Fourth and fifth strands 340,350: third strand 330 = 1: 1 to 2

When the first to fifth hair bundles 310 to 350 are arranged at the above-mentioned ratio, the back of the molar teeth, the back of the molar, and the back of the canine can be easily cleaned and the plaque between teeth and teeth can be effectively removed.

The first hair bundle 310 is positioned at the front end of the hair styling surface 210 so as to remove the plaque attached to the back of the molar. In addition, the four unit patterns 312 to 318 constituting the first pattern 310 are arranged in a semicircular pattern so as to cover the elliptical molar teeth. That is, the four unit patterns 312 to 318 are radially arranged around a point to form a semicircular pattern.

The four unit modules 312 to 318 have a fan shape extending toward the outer side in order to prevent the first hair bundle 310 from lying forward in the process of cleaning the molar teeth. In other words, when the toothbrush 1 is tilted to clean the rear side of the molar teeth, the first hair bundle 310 is pressed and easily deformed.

The second hair bundle 320 is positioned at the rear end of the wedge surface 210 so as to remove plaque attached to the back of the canine and the canine. The second pattern units 320 are composed of a total of six unit patterns 321 to 326 arranged three by three on the left and right sides, and are arranged so as to approach each other as they approach the rear end, thereby forming a V-shaped pattern. At this time, the unit molds 321 to 326 have a trapezoidal shape that becomes narrower toward the rear end of the mold opening surface 210.

The second pattern 320 of the above-described pattern can be brought into contact with the front teeth and the canines in a large area when brushing teeth, and at the same time, the plaque accumulated on the rear concave portion of the front teeth can be effectively removed.

The third tuft 330 is positioned at the center of the wedge surface 210 to remove plaque attached to the tooth surface. The third hair bundle 330 is arranged radially with respect to the center of the hair styling base 210 and is composed of a total of four sets of unit hair bundles 332 to 338 arranged at intervals of 90 degrees to form an X-shaped pattern. In addition, one set of unit molds 332 to 338 is composed of three unit modulates spaced outward from the center of the mold cavity surface 210. At this time, the unit pattern of the third pattern 330 has a trapezoidal shape that becomes narrower toward the center of the mold surface 210.

The third pattern 330 of the above-described pattern has a plurality of unit models arranged in a radial pattern. Therefore, even when the head 200 moves in either the forward, backward, leftward, rightward, or up and down directions at the time of brushing the teeth, Can be effectively cleaned.

The fourth and fifth hair bundles 340 and 350 are for removing the plaque accumulated between the teeth and the teeth, the fourth hair bundle 340 is disposed between the third hair bundles 330, The five bundles 350 are formed in an arc pattern.

The fourth hair bundle 340 is composed of two pairs of unit hair bundles 342 and 344 disposed between the third hair bundles and symmetrical to each other. The pair of unit molds 342 spaced forward and backward from the mold core 210 is composed of two pieces having a trapezoidal shape, that is, a total of four pieces. Further, the pair of unit molds 344 spaced to the right and left of the mold core 210 is formed in a circular shape.

The fifth hair bundle 350 has three arched units formed in a circular shape with a convex arcuate pattern forward.

The fourth pattern (340) of the above-described pattern is disposed between the third pattern (330) to prevent wear of the cervical portion when brushing toothpaste, and effectively remove the plaque accumulated between the teeth. In particular, when the fifth hair bundle 350 is additionally provided between the first hair bundle 310 and the third hair bundle 330 as in the present embodiment, the plaque can be more effectively removed.

On the other hand, the bundles 310 to 350 of the bristles 300 may have different lengths. For example, the first to third mold bundles 310 to 330 may be formed longer than the fourth and fifth mold bundles 340 and 350. More specifically, the first to third mold bundles 310 to 330 may be formed to be 0.5 to 3.0 mm longer than the fourth and fifth mold bundles 340 and 350.

When the first and second hair bundles 310 and 320 are formed long, the back of the molar teeth and the back of the canine can be easily cleaned. In addition, when the third hair bundle 330 is formed long, it is more protruded than the surrounding hair bundle (the fourth hair bundle 340), so that it can be effectively contacted with the tooth surface.

On the other hand, when the fourth and fifth hair bundles 340 and 350 are formed to be short, irritation caused by the hair bundles 340 and 350 can be reduced during gargling, thereby preventing the cervical portion from being worn. Further, when the head 200 is moved up and down to brush the teeth, the hair bundles 340 and 350 can be cleaned to the corners of the teeth, thereby preventing plaque from accumulating in the teeth.
