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

Toothbrush
Technical field
The present invention relates to high-quality green tea and can effectively arrive each position between tooth, and have the toothbrush of good descale effect.
Background technology
In the past, as removing the dirt between fine gap in the oral cavity, for example: remove the toothbrush of each position dirt and tartar between tooth, see from the side as can be known, it is provided with tip gradient in accordance with regulations with bristle and is cut into the bristle tuft that what is called that the tip surface that makes bristle tuft is chevron is cut into chevron.Have the toothbrush that is cut into the chevron bristle tuft, bristle arrives the effect between tooth, depends on the thickness (diameter) of embedded bristle (monofilament), and thinner high-quality green tea can be easy to enter into the depths between tooth, can take out stains and tartar.But, the bristle that diameter is thinner, because stiffness is poor, brushing teeth for a long time weakens the durability of embedding hair portion, and, the problem that descale effect reduces can appear.Therefore, the actual toothbrush that uses, bristle diameter can not be meticulous, and it is optimum that the diameter of normally used bristle should be 6-10 inch (0.152-0.254mm).
As mentioned above, known a kind of toothbrush, the area of section of its embedded bristle from the root of bristle to high-quality green tea are the cone-shaped that diminishes gradually (open clear 56-155628 communique in fact, open flat 6-154 communique in fact with reference to Japan).In this toothbrush, because the most advanced and sophisticated tapered shape of this toothbrush bristle, the most advanced and sophisticated thickness of bristle can be decided to be about 0.02mm, can effectively arrive each position between tooth like this, because the root thickness of bristle can be maintained at about 6-8 inch (0.152-0.203mm), though the durability of the embedding hair portion so brush teeth for a long time after the use makes moderate progress, but still the problem that exists descale effect to weaken.
Purpose of the present invention is to solve above-mentioned problems of the prior art, provides both to make high-quality green tea effectively arrive each position between the tooth, the toothbrush that can effectively take out stains again.
Summary of the invention
For achieving the above object, toothbrush of the present invention is provided with the required head of embedding hair, this head comprises a plurality of bristle tuft that are fixed in the embedding hair side, each bristle tuft in the toothbrush is made up of a plurality of bristles, the bristle tips of at least a portion of described a plurality of bristle tuft is cut by this way, that is, see from the side that the tip of the bristle on each bristle tuft or the bristle tuft group that forms with the bristle tuft of specified quantity is the shape on mountain.Each bristle of bristle tuft after the cutting is characterised in that like this, and the landform that all diminishes gradually of the area of section from the root to the high-quality green tea is tapered.
As mentioned above, the bristle tips of specified quantity bristle tuft is cut into chevron, makes cone-shaped owing to cut into the bristle tips of the bristle tuft of chevron, and the tip of bristle enters the depths at each position between tooth easily, effectively removes dirt and tartar.And because the tapered shape of bristle, the root of bristle can use the bristle with ordinary toothbrush same degree thickness, guarantees the stiffness of bristle, and suitable sweeping effect can be provided.
In addition, in the described bristle tuft that is cut into chevron, because the closer to the bristle at the chevron top that bristle tips forms, its tip is sharp-pointed cone-shaped more, makes high-quality green tea can enter the depths at each position between tooth, effectively removes dirt and tartar simultaneously.
And, above-mentioned a plurality of bristle tuft, also the bristle tips of a pair of bristle tuft that can each is adjacent is configured to chevron.
In addition, as: Japan open clear 56-155628 communique in fact, the real flat 6-154 communique, spy opened opened flat 6-141923 communique, spy and opened 2000-14447 communique or spy and open shown in the 2000-23746 communique etc., some tapered bristles are shown, and the area of section from the root to the high-quality green tea is the trend that diminishes continuously.But the continuous variation of area of section might not be necessary, also can discontinuously change.
And, the cross sectional shape of the bristle of taper is not necessarily rounded, as: the spy of Japan opens clear 58-15812 communique, the spy opens clear 60-88110 communique or real opening shown in the flat 1-59421 communique, has other tangent plane shapes except that circular such as ellipse or polygon and all can.
In addition, the tapering of tapering part (angle of inclination) is preferably the bristle all align, does not line up also passablely, does not have special qualification.For the making of tapered bristles, can use as: nylon monofilament is carried out attrition process or with the method for acid or aqueous slkali dissolved polyester monofilament (as: PBT) with grinder.
The used resin material that formation is had the toothbrush handles of head, do not have special qualification, can use as: polypropylene, polyethylene, PETG, polybutylene terephthalate (PBT), polyisobutene acid methyl esters, propyl cellulose, polyurethane, polyamide, benzene sulfonamide acid esters materials such as (ABS).From cost, use polypropylene ideal.

The specific embodiment of invention
Below, with reference to accompanying drawing embodiments of the present invention are described.
Fig. 1 and Fig. 2 are the demonstration figure that relates to a kind of form of implementation of toothbrush of the present invention.1 is head, and 2 is the neck that is connected with head 1, and 3 is handle portion, and a plurality of bristle tuft 5 are embedded on the embedding hair side 4 that is arranged at head 1.Many bristles (monofilament) 6 are pricked each bristle tuft 5 that constitutes respectively, and 2 adjacent bundle bristle tuft 5,5 are combined into 1 group, and the tip of its bristle is cut into chevron, and the tip surface of seeing bristle tuft 5,5 from the side press the inclination angle formation chevron of defined as can be known.
In the invention process form, the described bristle tuft 5 that is cut into chevron is made up of each bristle 6, and as shown in Figure 2, bristle 6 is tapered bristles, and it has the tapered portion 7 that diminishes gradually from root to the high-quality green tea area of section.And in the toothbrush as shown in the figure, the closer to the bristle 6 at the chevron top of the bristle tuft 5,5 that is cut into chevron, its tip is sharp-pointed cone-shaped more.
The toothbrush of Gou Chenging as mentioned above, in its adjacent right bristle tuft 5 that is combined into, 5 are cut on the basis of chevron, owing to constitute the bristle tuft 5 of chevron part, each bristle 6 tapered shape of 5, the tip of bristle 6 is easy to enter into the depths at each position between tooth, thereby, can effectively remove the depths at each position is adhered between tooth dirt and tartar.
And, in above-mentioned form of implementation, because the closer to the paired bristle tuft 5 that is cut into chevron, the bristle 6 at 5 chevron top, its point is sharp-pointed cone-shaped more, so near the bristle 6 that is positioned at the chevron top has more sharp-pointed bristle, can enter deeplyer.
Because every bristle 6 tapered shapes, the thickness of bristle 6 roots can be identical with general toothbrush.Therefore,, can guarantee the stiffness of hair, reach effective descale effect though used tapered bristle.
The manufacture process of above-mentioned toothbrush is, tapered bristle quantity on request is bundled into bristle tuft, after embedding the embedding hair side of toothbrush head, the tip end surface of bristle tuft is cut into chevron with desirable shape, must carry out the processing of high-quality green tea rounding to the bristle tips that formation cuts into the bristle tuft of chevron, perhaps, the grinding that high-quality green tea is carried out single or double makes it tapered.
