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 a fourth tuft 340 for effectively removing plaque between the teeth and teeth.

The first to fourth pattern bundles 310 to 340 of the present embodiment are formed of a plurality of unit patterns (one pattern block), and the unit patterns are arranged so as to have a constant pattern, and have the above-described functions. That is, the first model bundle 310 is arranged such that the unit model feet form a trapezoidal pattern, and the second model bundle 310 is arranged such that the unit model feet form an inverted trapezoidal pattern. In addition, the third pattern 330 is arranged such that the unit modal patterns form a * -shaped pattern, and the fourth pattern 340 is arranged to surround the periphery of the third pattern 330. At this time, the unit patterns of the first to fourth pattern bundles 310 to 340 have the same shape, that is, a shape of a slot extending in one direction.

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 three unit patterns 312 to 316 constituting the first pattern 310 are arranged in a trapezoidal pattern so as to cover the elliptical molar teeth. That is, the first pattern bundle 310 includes the first pattern 1-13 extending in the forward and backward directions, the first pattern 1-3 extending in the oblique direction and located on the right and left of the first pattern 1-13, Bundles 314 and 316, respectively. At this time, a pair of the first and second pattern groups 314 and 316 are symmetrical with respect to the first pattern group 312.

The first hair bundle 310 has a shape extending substantially back and forth so as 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. In addition, the three unit patterns 322 to 326 constituting the second pattern 320 are arranged in an inverted trapezoidal pattern corresponding to the first pattern 310. That is, the second hair bundle 320 includes a second-first hair bundle 322 extending in the fore-and-aft direction, a second-second hair bundle 322 located in the right and left of the second- (324, 326).

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 hair bundle 330 is located at the center of the hair styling surface 210 and has a serpentine pattern so as to remove plaque attached to the tooth surface. The third hair bundle 330 includes a third-first hair bundle 332 extended to the front and back of the hair-eating surface 210, a third hair bundle 332 positioned on the right and left of the third- And a 3-2 bundle (334). At this time, the third-first model bundle 332 and the third-second model bundle 334 are arranged symmetrically with respect to the imaginary line extending to the right and left of the cooking cavity 210 to form a * shaped pattern.

The third pattern 330 of the above-described pattern is formed such that when the third-first pattern 332 and the third-second pattern 334 are arranged radially around one point to brush the teeth, The contact efficiency with the tooth surface is excellent and the tooth surface can be effectively cleaned even when moving in the forward, backward, left and right, up and down directions.

The fourth hair bundle 340 is arranged to surround the periphery of the third hair bundle 330 for removing the plaque accumulated on the teeth and the teeth. More specifically, the 4-1 bundle 342 located between the 3-1 bundle 332 and the 3-2 bundle 334 and the 4-1 bundle 342 located between the 3 < rd > bundle 310 and the 3 & And a fourth pattern bundle 344 having a rectangular pattern positioned between the bundles 330.

The 4-1 bundle 342 is composed of three sets in total. In other words, the unit hair bundles positioned on the front side of the third hair bundle 330 and extending in the diagonal direction, the unit hair bundles positioned on both sides of the third hair bundle 330 and extending back and forth, 330 and is constituted by unit legs extending back and forth.

The fourth 4-2 stamper 344 has a rectangular pattern in which a pair of unit patterns extending in the left and right direction and a pair of unit patterns extending in the oblique direction are arranged in parallel.

The fourth pattern 340 of the above-described pattern has a plurality of unit model feet constituting the 4-1 pattern 342 and the 4-2 pattern 344 arranged in the forward and backward directions, the left and right direction, and the oblique direction, The wear of the cervical portion can be prevented, and the plaque accumulated in the teeth can be effectively removed.

On the other hand, the bundles 310 to 340 of the bristles 300 may be formed to have different lengths. For example, the first to third mold bundles 310 to 330 may be formed longer than the fourth mold bundle 340. 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 pattern bundle 340.

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 hair bundle 340 is formed to be short, it is possible to prevent the wear of the cervical part by reducing the stimulation by the hair bundle 340 when brushing the hair. Further, when the head 200 is moved up and down to brush the teeth, the hair bundle 340 can be cleaned to the corners of the teeth, thereby preventing plaque from accumulating in the teeth.
