Description

Akira fine manual toothbrush technology field

The present invention interdental penetration resistance, plaque removing function, excellent in appearance-discrimination, hair standing also relates toothbrush good flat wire flocking expression. BACKGROUND

Tairasen flocked type toothbrushes are planted by implanting the planting hole tresses folded in two using a metal strip or plastic pieces called Tairasen. Thus, flocking holes formed in the Uz de unit flocked surface to 'has a diameter 1. 5 to 2. 2 mm 1 to hole edge spacing planting pores adjacent a circular shape. And 0 mm or more, further, tufts of bristles also 1 Anato or brush number 1 6-6 0 present (3 folded number 2 - 1 2 0 present), the sum of the brush cross sectional area per hole in the folded state is 1. 0 mm 2 to use more of the thick tresses were common.

In the case of using the thick hair bundle as described above, if also the improvement of the minority of the hair waist planted pores number Sutame, there is an advantage that leads to an improvement in production efficiency. On the other hand, when a thick tresses, cervical a predilection of oral diseases, gullet, etc. impair access brush away small fissure groove of the occlusal surface, on oral disease prevention problem is left and, on the oral hygiene preferably wards.

That is, in the case of such a toothbrush, while capable of realizing a powerful cleaning effect by the thick tuft, will be each other supported by tufts between the brushing pressure to the hair bundle is thick, brush itself originally constituting the tufts can not be exerted supple movement have, gullet that is oral disease predilection, the bristles are less likely to reach the small clearance portion such as the interdental triangle. In addition, if the hair bundle is thick, other bad teeth between the penetration resistance, in Rigachi a hard and hair waist, even greater irritation to the oral mucosa. Furthermore, it is necessary to the hole edge spacing planting pores adjacent in relation to the intensity 1. 0 mm or more, even design restrictions since multi Kunar, poor novelty appearance-discrimination also low . Therefore, by In its contact with the conventional devising the shape of the head portion and the handle, color and the like, it has attempted to differentiate between products.

As this type of toothbrush, for example, Japanese Toku閧 2 0 0 0 - 3 0 0 3 4 6 No. Gazette, as well as the width of the bristle base to within 8 mm, the handle parallel to the longitudinal direction tufts 4 or more rows arranged, soft hide toothbrush is shown than tufts positioned tresses inwardly located further outward. However, this toothbrush is primarily those from the viewpoint of safety to mucosa in the oral cavity during toothbrushing by Bass method soften the outer brush, the present invention in which differing in the technical concept, planting not been made any investigations about the relationship between the cross-sectional area of ​​the brush to be planted and hole edge spacing of pores.

Further, the Japanese Patent No. 1 1 3 1 8 5 6 5 discloses, although toothbrush bristles were the filaments of rectangular cross-section bristles holes of oval shape is shown, the hole edge spacing planting pores not been made any investigations about the relationship between the cross-sectional area of ​​the brush to be flocked. For even toothbrushes and thin walled by narrowing the hole edge spacing of planting pores, for example Japanese Patent Rights 1 1 1 1 3 6 3 but No.4 shown like in Japanese, in the case of this toothbrush, the Tairasen spacing flocking holes implanted is only being secured in a fixed direction, further, it is not such whatsoever studies about the relationship between the cross-sectional area of ​​the brush to be planted and hole edge spacing of planting pores.

In addition, the Japan Toku閧 2 0 0 2 1 0 8 3 4 discloses, by selecting and combining planted pores serving long hole orientation as the orientation of the long axis is different, hardness directions different bristle toothbrushes mix arranged bundles further, Japanese, Japanese Unexamined 1 0 3 2 7 9 3 0 No. Ya Hei 1 0 3 2 7 9 3 1 discloses a number of bristles from the brush base It is projected, but many hair toothbrush to include a plurality of bristles of at least an oval cross section is that it shows, both in its relationship with the sum of the cross-sectional area of ​​the hole edge spacing and brush flocking holes It has not been made any of the study.

As described above, in the conventional flat wire bristle toothbrush employs a larger bristle holes from of Chasse of flocked, it was also set in the wider spacing of the bristle holes adjacent. For this reason, along with the hair bundle also becomes thick to use, it flocked the hair bundle interval between the widely tend der ivy

The requirements of the toothbrush, as well excellent in plaque removing effect, but safety for oral mucosa also required high points, in the case of the conventional flat wire bristle toothbrush, since tufts is thick, the tooth surface Although excellent in Sutin removal function, strong stimulation against the soft tissue, such as gum, it was careful attention must be paid to be used in particular for patients 齒周 flame and periodontal disease. Therefore, like the patient's 齒周 flame and periodontal disease, but cause use a toothbrush with a soft brush hair stiffness is usually sufficient plaque removal function for hair stiffness is soft there is a problem that can not be exhibited.

The present invention has been made to solve the above problems, and hole edge spacing between the planting hole closest, to set the optimum value and the sum of the cross-sectional areas of the brush to be planted in the planting pores by, excellent in plaque removing function of oral disease predilection, irritation to oral soft tissues also soft, yet aims at providing appearance-discrimination, the tooth brush of the feeling in use was excellent is there. Disclosure of the Invention

To solve the above problems, the present invention includes a head unit to have a flocked surface planted pores are formed, a bristle bundle, each consisting of a brush of the plurality, is it to the bristle holes of the flocked surface it and have your toothbrush that includes a plurality of tufts have been conducted under the flocking the flat line in the folded, at least a portion of the flocked hole, the hole edge interval between any planting holes closest 1. 0 with mm are arranged below the tuft which is planted bristles on at least a portion of the bristle holes of said sum of the cross-sectional area of the folded bristles portion is 1. 0 mm 2 or less per well it is those that were set up as.

The sum of the cross-sectional area of the brush portion is preferably 0 per planting hole 1 hole. 1 0-0. Of 7 0 mm 2 range. Further, hole edge spacing between at least a portion of the bristles hole and recent contact planting pores above, preferably 0. 2 5~0. 7 0 mm range. When brush sectional shape is taken as an example the case of a circular, sum 1 of the cross-sectional area of the folded brush portion. 0 mm 2 or less and become the 1 a brush of 7 mil (diameter 1 7 8 mm) approximately 5-1 4 per well, i.e. corresponding to 1 0-2 8 a brush portion of the folded state.

The brush number is toothbrushes specifications and brush diameter on design, it can be appropriately set by such cross-sectional shape. The sum of the cross-sectional areas of the brush to be planted in a single bristle holes 1.0 When mm 2 to exceeds, the strength of the tufts becomes large, extremely flexible tufts become high tuft rigidity It drops to, which is not preferable.

Further, 1 is the sum of the cross-sectional area of the brush. 0 hole edge distance between any planting holes mm 2 to less flocking holes planted the hair bundle and the closest is 1. O mm or less, more preferably 0. in the range of 2 5~0. 7 O mm. When the hole edge interval is too narrow, the distance between the hair bundle also becomes narrower, brush can not enter between the teeth, the teeth between the penetration resistance is lowered. On the other hand, when the hole edge spacing Ru spread, appearance-discrimination, is feeling decreases. When planting pores interval is greater than 1. O mm, blanking lashing repulsion of the hair bundle associated with the movement becomes stronger, Goggodzu to feel pressurized despite the hair bundle, not only the feeling of use is reduced, and a series of hair bundle movement is not exerted, also decreases plaque removal effect.

Toothbrush of the present invention, the thin because the tufts are arranged at optimal intervals, one by one brush becomes easier access to the tooth and gums, bristle tips of accessibility to the oral disease predilection is improved that. Furthermore, the flocking of tufts consisting of a small number of brush number, continuous movement of the thin tuft been made hitherto impossible can be expression, excessive load on the cervical, oral mucosa, such as interdental papilla without imposing, plaque removal, it is possible to express the gingival massage function. Toothbrush Thus, the present invention has excellent plaque removal ability definitive in oral disease predilection highly safe for oral soft tissues, deer the appearance-discrimination, is also excellent in usability.

Satisfy the above conditions flocking holes may be formed at any position of the head portion flocked surface to but to place a portion of the outermost of at least the head portion flocked surfaces are preferred. With this configuration, during brushing, easily brush is in contact with the tooth surface, it is possible to further improve the interdental penetration resistance. In this case, printing 掃実 feeling and design, from the standpoint of productivity, if to place a thick tufts near the center of the head portion flocked surface, it becomes more preferable.

Hole cross-sectional shape of the bristle holes may be circular or square commonly used, but elliptical or substantially elliptical, oval or oblong, such as a rectangle or substantially rectangular, the short axis in the hole section (minor axis or preferably in the hole shape of the profile with a short-side direction) and longitudinal direction (major axis or long side direction). In this case, as the plant pores, Shi dimension ratio of the major-axis direction against the short-axis direction of 1.0 desirable to use a flocking holes of larger hole shape than Les. Further, by setting the arrangement in various combinations the direction of planting pores, it is possible to design specifications in accordance with the per comfort, printing 掃実 feeling hair of interest. Furthermore, by devising the orientation of the bristle holes, it is possible to change the appearance of the hair bundle from the side, for example, along the head portion minor axis side edges of the bristle holes located outside the flocked surface to arranged so as a result, looked thin in comparison with the hair bundle of circular was planted a brush of the same number, appearance-discrimination can be improved. Further, in order to Hairy reduction than at the same time avoiding interference flat lines of the planting holes adjacent arrangement of planting pores may be staggered.

Also, if devised a driving direction of the flat wire for planting pores can be as small as possible a clearance between the bristles have been tresses and planting pores, to create a good flocked portion of hair falling it can. That is, Uchikome a flat wire along the longitudinal direction of the planting pores, because the lined brush along Tairasen, flocked strength is improved. Further, since the tufts of the fart head portion outermost by a driving direction of Tairasen look thinner, it is possible to improve the appearance-discrimination. Flocking hole shape in this case, substantially rectangular it is preferable to reduce the distance tufts with flocking holes. Further, when driving a flat line along the short axis direction, by matching the short axis direction of the diameter as the flocking holes in the outer Se'en against tuft cross section, fewer space between planting pores and tufts it becomes possible, it may construct a excellent flocked part of hair falling. At this time, brush cross section to be used in the case of circular, substantially elliptical planting pores shapes, substantially elliptic, and more preferably be substantially rectangular.

Toothbrush head section, shape, size, with design, not subject to any restrictions. Also, the material of the flat wire used in a toothbrush, brass, other metals such as stainless steel, can also be used such as hard quality plastics and biodegradable plastics. Further, it is possible by adjusting the Thickness of Tairasen, reducing the gap reliably fixed to the planting pores and hair bundle. The flat wire width used is not particularly limited, it can be set arbitrarily.

The handle material of the toothbrush including the Uz de unit to, polystyrene resin (PS), polypropylene resin (PP), polyethylene terephthalate evening rate resin (PET), xylylene methylene terephthalate one graft into saturated polyester resin (acid-modified polycyclo polymer one [P .CTA], the glycol-modified polycyclo-xylylene methylene terephthalate one Tokoporima one [PCTG], etc.), acrylonitrile butadiene styrene resin (ABS), cellulose propionate resin (CP), polyarylate resins, polycarbonate resins ( PC), acrylonitrile-styrene resin (aS), poly Asetaru resin (POM), polybutylene terephthalate evening rate resin (PBT), materials such as poly Echiren'nafu evening rate resin (PEN) alone or in combination can and Mochiiruko. Further, the multicolor molding handle and to Rukoto in combination with a thermoplastic elastomer one are also preferred. Note that the handle material is not intended to be limited to the above. Brush The (filament) material, polyethylene terephthalate evening rate, Poripuchi Renterefu evening rate, polyesters such as polytrimethylene terephthalate one preparative, Na Iron 6, nylon 66, nylon 6-10, nylon 6-12, such as nylon 12 polyamides, Poryechiren, polyolefin such as polypropylene, polyvinyl halides such as polyvinylidene fluoride, although melt-spinnable materials are utilized, feeling, in terms of durability, nylon, polytrimethylene terephthalate chromatography door is preferable. Moreover, or as a brush having different outer and inner material by molding these brush double core sheath, or a different brush of the surface state, it is possible Rukoto used according to the purpose.

The brush Thickness,. 3 to: L 0 mils (. 0. 076~0 2 54mm), preferably rather may include the 5-8 Minore (. 0. 127 ~ 0 203 mm), usability, printing 掃感, cleaning effect, in consideration of durability, it is also preferable to use a combination of these. In particular, in many toothbrushes specification flocking holes disposed, toward the outside of the hair bundle in the center, or to hard hardness brush, thickness, material, length, color, be varied sectional shape, a feeling of use, and more preferably from the top of the exterior differentiation.

The brush type, a hair usually round (brush with rounded bristles), tapered bristles (brush that is tapered), diamond bristles (brush cross section diamonds), hair (bristles for Fuweza one brush divided into feathered), modified cross-section bristles (brush cross section is not circular), gray twenty-one bristles (brush kneaded abrasives), hair spiral catch (spiral groove is formed and brush), such as a hair indicator Isseki (brush informing replacement time due to wear of the outer layer has a double core-sheath structure the outer layer is colored), it is possible to take advantage of various things. It should be understood that even brush type is not limited thereto. Further, with respect to the brush, by setting the hair cutting (or profile) shape and brush length of the free end as appropriate, or a tuft tip surface with a single plane, or a mountain cut shape, it is a concavo-convex shape can. Furthermore, the outer and inner bristle face may be tufts structure differed like the previous end and the rear end portion. BRIEF DESCRIPTION OF THE DRAWINGS
