Abstract

An improved toothbrush is disclosed. The toothbrush contains bristles which are individually embedded in a toothbrush head and mutually spaced apart from one another by a distance from 0.5 times to 10 times the diameter of the bristles. The bristles may include first (3) type bristles having a diameter of from about 0.25 mm to about 0.60 mm; second (5) type bristles having a diameter of from about 0.08 mm to about 0.35 mm and a free length of from about 7 mm to about 16 mm; third (6) type bristles having a diameter of from about 0.15 mm to about 0.40 mm and a free length of from about 5 mm to about 14 mm; fourth (7) type bristles having a diameter of from about 0.15 mm to about 1.0 mm and a free length of from about 9 mm to about 15 mm; and a raised dense tuft (8) of bristles at the end of the toothbrush head distal from the handle.

Description

Toothbrush with bristle of an embedding
The present invention relates to toothbrush.Spacing distance is short each other by the upright plastics bristle of one one embedding toothbrush head for the feature of toothbrush of the present invention.May there be several different bristle arrangements in head at a toothbrush, and each has unique oral cavity function purposes.
Conventional toothbrush is to be attached on the plastic cap of toothbrush by the bristle (" tuft ") with cluster.Can make and adhere to these tufts in many ways.In a known method, each tuft is formed by a large amount of independent bristles that is converted into U-shaped.Then these tufts of being rolled over are inserted in the eyelet or chamber in the head toothbrushes.By small pieces metal (being called " anchor " or " stapler ") is inserted in the chamber so that the bottom of this U-shaped tuft and be fixed between the bottom and nail in this chamber, thereby the tuft that each is rolled over is fixed in separately the chamber.Each is also referred to as " bristle root " sometimes by the part that folding tuft is fixed in separately the chamber.As referring to No. the 3590438th, United States Patent (USP), this paper will fit into as a reference in this article.According to producer's the design and the purposes of toothbrush, tuft all is to be made by the independent bristle that the 2-60 root generally has the length of the diameter of about 0.15-0.25mm and 7-13mm.For example, " soft " bristle toothbrush may have and the bristle of " medium " bristle toothbrush different length and diameter.
In another manufacture method, each tuft also comprises a large amount of independent bristles.A large amount of tufts that comprises many independent bristles is inserted in first mould in separately the hole, and like this, this tuft stretches out certain-length from a side of this mould, and this section tuft will form the inner surface of brush body die cavity.Then, each tuft block of having at least part that a part stretches out to be fused into to have greater than the cross section in the hole of this first mould inboard.This first mould is connected with second mould, limiting the die cavity of brush body, and moulding material is injected this chamber, to form final brush product.As referring to United States Patent (USP) 4635313, this paper will fit into as a reference in this article.
This method has been considered may be than the complexity of the stapler tuft densification of standard and the creation of asymmetric tuft model.
WO 93/12690 discloses another makes brushing cluster be fixed to method on the brush carrier, and this paper will fit into as a reference in this article.
A problem using bunch shape bristle to make the toothbrush generation is that the bristle that constitutes the tuft structure can not arbitrarily crooked and independent bending.Therefore, bunch shape bristle can not make cleaning of teeth like that effectively with arbitrarily moving along irregular contour independently according to the configuration of tooth.In addition, the structural limitations of tuft the freedom of motion of single bristle, especially at other various freedom of motion in shape of tooth tip, groove and tooth.In addition, the major diameter that passage also is subjected to the brushing cluster of fine and close assembling between the neighbour of bristle limits.
Using bunch shape bristle to make another problem that toothbrush produced is that toothbrush usually can sufficiently dry before using after use next time.This be because bristle by the reason of sheave, this way makes that the capillary between bristle is narrow and small.Use in may be between the bristle narrow and small capillary of moisture left behind the toothbrush and keep for a long time.These moisture provide condition may for bacterium and microbial growth.If toothbrush twice is used in suggestion every day at least as dental professional, then the blanking time of twice use long enough possibly so that the toothbrush sufficiently dry.This problem is especially outstanding at the near zone of the toothbrush head of pasting bristle.Dust granules or to remain in the working medium that capillary neutralization can not fully remove be that toothpaste has additionally promoted this influence.The incomplete removal of toothpaste residue when the space relatively closely of bristle may cause toothbrush to use the back to clean in the root area.
Therefore, need a kind ofly to provide that effective cleaning of teeth is handled, self is easy to clean and at the toothbrush of short relatively time inner drying.
International patent application WO discloses a kind of article No. 96/27308, and these article contain brush carrier and bristle cover.This bristle cover contains mutually non-touching individual plastic bristle.The document is mentioned, and the bending stiffness of bristle is crucial to the validity of toothbrush.The rigidity of whole bristle cover not only can be changed by size (diameter, length) and the bristle material of the bristle selecting to change, can also be changed by the space between the bristle of selecting slightly change.On the basis of the distance between the outside neighbouring surface of bristle, bristle spacing distance spatially can be about 0.5-4 times, especially 1.5-2 times of its diameter.Bristle also can have the rigidity of change, for example, the diameter of change and/or at interval, wherein, bristle in groups has identical rigidity in same group, and on the same group the rigidity difference of bristle not.Free-ended bristle lengths from the brush carrier to the bristle can change.Can be fabricated, assemble or wrap quilt on these bristle surface.The free end of bristle also can become certain shape.
Term used herein " free end " refers to that bristle pastes the end of the point on the toothbrush head away from it.
In the toothbrush of routine, rigidity is basically by the diameter decision of bristle cluster density and each bristle in the length of tuft and the tuft.Back one factor influence minimum make bristle in tuft, support mutually because the bending stiffness of tuft is several times result of single bristle.Because the distance between the bristle in the article described in the WO 96/27308, bristle diameter is decision rigidity role big during than bristle cluster shape.WO 96/27308 does not address the most important factor of suitable bristle lengths or these two decisions of diameter bristle rigidity.
International patent application WO has described for No. 99/07252 has plastic bruss burr portion and one one toothbrush that embeds the upright plastics bristle of this bristle head.Bristle is separated from each other the distance of one section weak point.Only under the situation to every square centimeter of bristle cluster density with 400-800 root bristle on the brush head, this is only appointment at interval.The document discloses best bristle density, and promptly 600 bristles are every square centimeter.The diameter that the document also discloses that bristle is about between the 0.095-0.225mm.The document points out that the bristle drift is short more, and the diameter of selecting to be used for to keep rigidity is more little; The total height of the toothbrush on the bristle head zone is 6.5-11mm; The thickness of bristle head is 1.5-3mm; The bristle drift is 5-9.5mm.Because the bending stiffness of single bristle is significantly less than the tuft that contains a large amount of bristles with equal height and diameter, so this patent application discloses diameter and the identical use than short bristles of conventional bunch shape brush bristles.Toothbrush with separate bristle can also change its bending stiffness in the mode of accurate classification by the interval that changes between bristle.
WO 99/97252 also describes, and the separate bristle toothbrush provides surface, no gap, and this needs for cleaning of teeth.This is the advantage of separate bristle technology.Because each bristle energy self-movement is so there is how little irregular configuration to be cleaned simultaneously in the tooth configuration.The whole surface of toothbrush bristle all is used for carrying out cleaning, thereby with respect to bunch shape brush of routine, this toothbrush more effectively provides better cleaning fully.Though the sum of the bristle on the conventional toothbrush is roughly the same with this new separate bristle toothbrush,, it is believed that this new toothbrush has 1000 clean surfaces (separate bristle) of surpassing, and conventional toothbrush just has 40-50 clean surface (tuft).
The diameter of typical bristle is about 0.15-0.25mm in soft bunch of shape toothbrush, and drift is about 8-12mm.The size of using in disclosed size and the conventional bunch shape toothbrush in the above-mentioned document is very similar, still, because the bristle in the document is single embedding, so its bending stiffness contains the bending stiffness of the conventional toothbrush of a large amount of bristles basically less than its single brushing cluster.Therefore, the toothbrush that embeds its head with single bristle described in the above-mentioned document brings several problems to the consumer.A problem is, though in order to adapt to the profile of irregular tooth configuration, need bristle to have some bendings, if bristle is too soft, it is cleaning teeth fully, thereby too much bending is disadvantageous.Bristle will not have enough intensity to remove dental plaque, food debris etc.Though people do not want to make bristle so stiff undoubtedly so that it damages oral soft tissue or sclerous tissues, however, still need a certain amount of rigidity, to carry out the cleaning function of toothbrush.
Second problem relevant with the disclosed toothbrush of above-mentioned document is that the consumer thinks that these toothbrushes are too soft, can not carry out cleaning, and some is stiff.Though the damage that does not need to make so stiff toothbrush so that cause oral cavity tissue need have some minimal rigidity, actual cleaning function to be provided and the consumer is produced the consciousness that reaches cleaning effect.The consumer may think, so soft toothbrush can not be removed dental plaque on the tooth, food debris etc.When being used for bunch individual bristle of shape toothbrush by single use, so that the consumer is when producing the consciousness that obtains actual cleaning effect, the bending stiffness of these bristles is too low.
Three problem relevant with the disclosed toothbrush of above-mentioned document is, because the bending stiffness of individual bristle is more much smaller than the rigidity of the tuft that contains many identical bristles, and there be not supportive bristle to make bristle after distortion, turn back to stand up position near the periphery, so bristle might no longer occur with upright form separately, and bristle is in vertical position after use usually.On the contrary, these bristles obviously are less than under bunch situation of shape toothbrush at access times and occur from the situation of toothbrush head to all directions bending (" opening ").For the consumer, open toothbrush is bad, can not re-use.Clinical research in the document shows that also these open toothbrushes are compared with the identical toothbrush with new upright bristle, no longer have cleaning function.
Four problem relevant with the disclosed toothbrush of above-mentioned document is that the consumer thinks that the service life of this toothbrush can be the same not long with bunch shape toothbrush after inspection.Have separate on the space, independently the toothbrush of bristle is considered to not have and bunch identical elasticity of shape toothbrush, thereby need soon to change.The main reason that produces this problem is to it is believed that not help to keep other upright bristle of each bristle.Because open result also is the main signal that the consumer changes toothbrush, so this product should not be bought owing to its short life of product.
Therefore, although there is the disclosed content of above-mentioned document, still need a kind ofly to provide effective cleaning teeth function, self is easy to clean and can dry toothbrush in the short relatively time.We find amazedly, and length but bristle that diameter bigger similar to bunch length in bunch shape toothbrush will solve or greatly reduce the problems referred to above.The length thicker bristle similar to the length in the conventional bunch shape toothbrush not only provides bigger rigidity to toothbrush, thereby provides the more perceptible sensation of scrubbing to the user, arrives between tooth and the required length of gums lower area but also kept.The intrinsic stronger structural support of this thick bristle is opened with resistance, and the bristle less with respect to diameter, that length is identical, and this bristle can be kept its upright shape in a long time.
In one embodiment, toothbrush provided by the invention has: handle; Toothbrush head at the handle far-end; The bristle of a large amount of first kind, the diameter of each bristle is about 0.25-0.60mm; Wherein, the bristle of this first kind is fixing by one one, as is embedded into toothbrush head; These bristles doubly spatially are spaced from each other to the distance of its diameter with 0.5-10.
