Abstract

A toothbrush excellent in accessibility of bristle tips to interdental portions and also in brushing response. A plurality of brushing bristle tufts (5) are fixed to the block head (4) of a head unit (1). The bristle tufts (5) are cut on a tuft basis or specified-number-of-tufts basis so that the tip faces of the tufts (5) give mountain shapes. Each bristle (6) in the cut tufts (5) is tapered so as to be gradually reduced in section area from its base toward its tip; the closer to the top of a mountain shape formed by bristle tips a bristle (6) is, the sharper its tapered tip is.

Description

Akira fine manual toothbrush technology field

The present invention has excellent hair reachability to gullet, to better toothbrush in printing 掃実 feeling.

Background skills

Conventionally, fine gaps dirt in the oral cavity, for example, as a toothbrush order to remove dirt and plaque gullet, to form a ridge where the distal end surface of the brush bundle formed of a predetermined inclination angle as viewed from the side those with a brush flux that has the so-called mountain cut Katsuhito was Katsuhito a brush tip is known to. In the case of a toothbrush having the mountain cutting force Tsu door has been brush bundles, interdental reach of the brush depends on the thickness of the brush that has been planted (monofilament) (diameter), the hair as deep into the gullet thin There tends to penetrate, thereby enabling dirt and dental plaque and child removal. However, thin brush as easy city in diameter, for hair waist weak, low durability of the flocked portion due to long-term brushing, also, there is a problem such as lower printing 掃実 feeling. Therefore, in the toothbrushes to be actually used, can not be narrowed so much the thickness of the brush, usually 6-1 0 mil (0. 1 5 2~0. 2 5 4 mm), such a suitable degree thickness of I was using a brush.

In contrast, the toothbrush the cross-sectional area toward the hair tips from brush base side is flocked with brush of successively smaller Te one per shape (Japan Kunizane HirakiAkira 5 6 - 1 5 5 6 2 8 No., actual No. see 6-1 5 4 No.) are also known. In this toothbrush, since the brush tip is a tapered shape, a the brush tip thickness 0.0 to about 2 mm thinner can be Rukoto is excellent in accessibility to the gullet, brush mill proximal thickness 6~8 (0. 1 5 2~0. 2 0 3 mm) because it can you to maintain a certain degree of thickness, such as, durability of flocked portion by prolonged brushing can be assumed to be excellent, printing 掃実 sense there has been a little weak with the problem when was.

The present invention has been made to solve the above problems, is excellent in the hair of the accessibility to the gullet, moreover, an object of the invention to provide a superior toothbrush in printing 掃実 feeling . Disclosure of the Invention

To achieve the above object, the toothbrush of the present invention includes a head portion having a bristle surface, and a plurality of brush bundles fixed to flocked surface of the head portion to said each brush bundle of a plurality of brush in consisting toothbrush, at least in part, brush Tabagotoma other brush tip so that the Teisu chevron shape when viewed brush tip from the side for each brush bundle group consisting of brush bundles a predetermined number of said plurality of brush bundles together There has been Katsuhito, each printing hair this Katsuhito been brush bundle is characterized in that it is a tapered shape that its cross-sectional area from the base side toward the bristles is reduced.

When such a configuration, the brush tip of the brush bundle of a predetermined number are cut so that the chevron shape, since each brush tip of the mountain cut Katsuhito been brush bundles is te one par shape, brush tip easily penetrates deep into the gullet, it can remove dirt and dental plaque in effectively. Further, since the brush tapered, it may be a thickness of as much as a brush which is used to group side thickness of the brush in normal toothbrush bristles hips moderate to sufficient brushing it can give the feeling.

Incidentally, brush flux the mountain cut cut by the tip as close have brush atop chevron brush tip is formed with sharper tapered entering the hair to a more deep 'interdental it is to be able, more effectively dirt and dental plaque can and child removal.

Further, the plurality of brush bundles brush tip of the brush bunch of the pair of adjacent may be disposed so as to form a chevron.

Note that the brush of the tapered, for example, Japanese Kunizane HirakiAkira 5 6 1 5 5 6 2 8 No., actual No. 6-1 5 4 JP, Hei 6 1 4 1 9 2 3 No. , JP 2 0 0 0 - 1 4 4 4 7 JP or JP 2 0 0 0 - 2 3 7 4 as shown like in 6 JP, its cross-sectional area from the brush base side toward the hair tips Although but is intended to refer to a brush will continuously small summer necessarily cross-sectional area need not be continuously changed, in which may vary Unfortunately continued basis. Further, brush the cross-sectional shape of the tapered shape need not be circular, for example, daily home JP 5 8 - 1 5 8 1 2 JP, Sho 6 0 - 8 8 1 1 0 JP, Alternatively, as shown in the real No. 1 one 5 9 4 2 1 JP, like elliptical or polygonal, but may be another cross-sectional shape other than circular.

Further, the taper of the tapered portion (inclined angle) is more preferably have Assortment one in all brush may be irregular, not particularly limited. To create a brush tapered, for example, a nylon monofilament can be obtained by polishing by have use the grinder, also by dissolving a polyester mono filler main cement (e.g. PBT) using an acid or alkali solution it is possible to obtain.

Note that the there is no particular limitation to the resin constituting the toothbrush handle having a head portion, for example, polypropylene, polyethylene, polyethylene terephthalate evening rate, port polybutylene terephthalate evening rate, polymethyl evening methyl acrylic acid, cellulose propionate , it is possible to use polyurethane, polyamide de, ABS and the like. Particularly, polypropylene is preferable from the viewpoint of cost. BRIEF DESCRIPTION OF THE DRAWINGS
