Abstract
The invention relates to a brush for the dosed application of a cosmetic or pharmaceutical liquid, said brush being fitted with a number of bristles which extend at least substantially parallel to each other and which are grouped around a center of fitting (7). The bristles are injection-molded onto a bristle support (1), the fitting having an outer fitting region (3) enclosing the center of fitting in the peripheral direction, in which region the bristle density is higher than in the inner fitting region (4) enclosed by the outer fitting region (3) and/or the bristles of which are finer than the bristles in the inner fitting region (4).
Description
The present invention relates to the hairbrush of preamble according to claim 1.
Hairbrush discloses very different shapes in the prior art.Coating liquid has group usually with hairbrush, and this group is diverse by material, the very thickly bristle adjacent one another are or that directly be close to of integral body or bunchy forms.Because bristle is closely adjacent to each other or contacts, so bristle pack shows obvious capillarity.Thereby can pick quite a large amount of coating liquids of wanting.
The liquid that bristle pack picks is sent by bristle pack again, particularly, utilizes bristle pack to skim in surface to be processed, thereby with the bristle of Surface Contact part the liquid of its parcel is passed out to surface to be processed.Liquid flow to the area of bristles of wiping on pending surface from further being positioned at inner bristle pack zone.Longer in the bristle pack of wanting to skim over above the treatment surface, it is just more that bristle pack passes out to the liquid of wanting treatment surface, until use up the storage capacity of bristle pack.Afterwards, when the user wished to continue coating liquid, it must reuse the liquid-soaked bristle pack that is given for processing.
In traditional hairbrush, although the liquid measure that picks can be regulated (especially about brush amount, bristle thickness and bristle lengths) relatively goodly, yet structurally only " how many liquid measures of picking that hairbrush is sent again " are produced less impact in determining chronomere.As stating, the liquid measure that per time unit sends obviously depends on the user,, depends on how mobile hairbrush of user that is.
In addition, the bristle that fits tightly very much in the prior art also is imperfect, and this is because after very short time, just depositing a part wants coating liquid between the bristle, this part no longer is sent, and this is uneconomical, unhygienic on the other hand on the one hand in cosmetics and medicament hairbrush.
In view of this, task of the present invention is to realize a kind of hairbrush with bristle pack, and the help that utilizes bristle pack is the amount to be applied of metering liquid better.
This task utilizes the feature of claim 1 to solve.
Hairbrush of the present invention has the group that is comprised of some bristles of arranging of at least roughly extending parallel to each other.Arranging certainly that almost parallel extends also comprises following situations: some bristle longitudinal axis have formed less than 10 °, are more preferably less than 5 ° angle only.According to ideal style, bristle even except unavoidable manufacturing tolerance, be set parallel to each other fully.
The bristle pack of hairbrush of the present invention preferred (integral body is seen) at least roughly is circular fully in other words.This very importantly can at first realize being conducive to the quantitative performance of the present invention in the bristle pack in other words fully, if bristle pack has rectangle or square bottom surface, the liquid of quantitatively smearing " scatters " and may no longer fully controllably send, thereby in most of the cases is controlled no longer substantially quantitatively.
Preferred self is annular, and perhaps longitudinally tapered bristle is arranged in groups around group switching centre, and is rounded according to ideal style.Best is, each bristle consists of respectively ranks, and these ranks have the annulus profile.
It is adjacent to make progress in week, distribute the adjacent bristle in ground at its root area according to ideal style along circumference, in rounding (perhaps bristle utilizes this rounding transition to enter bristle supports) top, with at least 1/5 of its respective diameters, better with at least 1/4, keep each other the interval with at least 1/3 in the ideal case.Yet according to ideal style, compare in the maximum bristle diameter that described root area has with bristle, the maximum spacing between two this adjacent bristles is little at least 25%, and is better little by at least 40%.
Adjacent diametrically, the bristle that distributes along the adjacent circumferential line according to ideal style is at its root area, in rounding (perhaps bristle utilizes this rounding to transit to bristle supports) top, with at least 1/5 of its respective diameters, better with at least 1/4, keep each other the interval with at least 1/3 in the ideal case., compare with the maximum bristle diameter that bristle has in described root area herein, the maximum spacing between two this adjacent bristles according to ideal style little at least 25%, better little by at least 40%.
The length of employed bristle is preferably 2mm～10mm, is 2mm～5mm according to ideal style.
Bristle is formed on the bristle supports with one pack system or bicomponent injection molding, and it can be individual member, yet also can be the integrated component of handle.Bristle is one pack system injection molded there preferably, is once making in " injection " with bristle supports.
The group have outer group the zone, its together with group switching centre interior make progress in week Perfect Ring around interior group the zone.With by outer group of zone around interior group of zone in compare, outside this group zone in bristle density larger.The term bristle density can be understood as the brush amount of per unit area.
Alternative or additionally, outer group of so design of zone, that is, its bristle is more very thin than the bristle in interior group of zone.
Bristle set-up mode of the present invention allows hair brush area so to design, that is, the liquid that smear consists of unique drop in applicator central area based on its surface tension, this drop until its smear according to the rules, always by around bristle keep.
The invention reside in and realized a kind of bristle pack, it can so be set, namely, bristle pack has been dripped liquid measure that may be excessive (hair brush area at first may pick this liquid measure and hair brush area and keep this liquid measure because " supersaturation " can not be stored for more time when hairbrush immerses) in reality and afterwards, has been consisted of at last a drop.Yet this drop drips no longer immediately now.On the contrary, it is stored in the bristle pack, and and if only if smear begin and its with want in the treatment surface contact process, ability discharge again from bristle pack.
Can realize being different from the principle of smearing that present known hairbrush is smeared principle with method by this way.Instruction of the present invention can realize so designing hairbrush, that is, liquid to be applied no longer is continuously but sends with the amount that does not limit, but so design namely, is sent rapidly the overwhelming majority of the liquid of hair brush area storage with Surface Contact to be processed the time.According to ideal style, the part of sending rapidly be hair brush area storage liquid at least 75%, more preferably at least 85%.
The following fact helps to realize above-mentioned situation, that is, the bristle injection molded can stipulate to keep each other limiting accurately spacing thus.The significant fact is, allows targetedly Material Used by the manufacturing of injection molded method, and these materials are roughly resisted diffusion in the liquid.If select targetedly bristle spacing and bristle material to be not enough to the degree of emptying (on seeing) that reaches required, the surface texture of hydrophobic or hydrophilic additive being set targetedly and/or working by this way for so the injection molded bristle.
By these measures, predetermined relatively accurately in respective design hair brush area situation, which type of volume the liquid of sending by this way partly has.
Certainly can not stipulate general rule for the Exact Design hair brush area, because this depends on the indivedual situations that concern under the concrete condition to a great extent, that is, depend primarily on viscosity and surface tension and bristle density, bristle diameter and the bristle lengths of wanting coating liquid.Yet the principle of the invention that has further described below those skilled in the art have read, it is easy to determine under individual cases for the occurrence of realizing these parameters that the present invention observes by Specialty Experiment.When it was tested, those skilled in the art operated according to the rules the 3D sample and print.Utilize its help, those skilled in the art can be at the auxiliary lower experiment hairbrush of making very rapidly the bristle with different bristles or systematic change of CAD, to study corresponding bristle pack with respect to should be with the shown corresponding drippage characteristic that goes out of the liquid that hairbrush is processed.
The principle of the invention is based on realizing a kind of outer group of zone, and an edge has been realized in this outer group zone, and described edge will be impaled and make its deflection bristle pack center by the liquid that bristle pack picks.The principle of the invention is also based on realizing a kind of interior group of zone, and bristle density is that degree like this ground reduces within it, that is, the liquid that is picked by bristle pack in this zone no longer fully but hold back by the capillary effect between the bristle with reducing.Therefore, the liquid that is picked by bristle pack and finally be retained in after hairbrush drips according to the rules in the bristle pack becomes last drop at interior group of region clustering.At this, the bristle that also exists in interior group of zone has stoped the drop accident to be lost, and that is to say, just stops (in the stage, at least every hairbrush that infiltrates by immersion at least all can experience this drippage stage at described drippage) at drippage in the stage.
In other words, drop remains in the bristle pack astatically, and in the design predetermined time by bristle pack, this time surpasses the time range in drippage stage at least.In case keep the bristle of this drop and/or drop outer surface self to contact with pending surface, the power that so drop is retained in the bristle pack astatically just is overcome, drop roughly is sent pending surface fully.
Can realize thus obviously carrying out quantitatively to the hairbrush coating liquid better than present prior art.
This effect not only can obtain by the variation of bristle density, and similarly also can control by the very thin degree of bristle, that is, by not on the same group the diameter that has of regional bristle control.
In most of the cases it is desirable to, the very thin degree of bristle density and bristle changes simultaneously.Thus, depending on different situations, be adapted to particularly well the needs of concrete condition.
Importantly, the present invention utilizes the bristle of injection molded to put into practice with regard to successfully realizing the present invention.Because only work as bristle by the injection molded manufacturing, just can expect mode and required precision control bristle spacing and the very thin degree of bristle.
Stipulate that in a preferred embodiment of the invention interior group of zone comprises and account for the only central area of a part, its surface that this central area is fully without bristles.(that is, the viscosity of liquid to be applied or surface tension are corresponding higher) can be expected designing interior group of zone fully without bristles under individual cases, yet this is not preferred.
Stipulate that in the improved procedure of above-mentioned preferred embodiment interior group of zone (preferably distributing along the imaginary circle contour) has the border bristle, this border bristle defines spatial volume without bristles at group switching centre.Described spatial volume consists of the drop space that can quite accurately limit, can gather at least first of described " last " drop in the described drop space, described first is so big, namely, when contact pending when surface, its sudden outburst the overwhelming majority of droplet-like liquid to be applied.In the heart zone this without bristles helps to form drop desirable, that after this keep by bristle pack astatically in the bristle pack.
This is so to occur, that is, can be without hindrance in the central area by bristle or by assembling the first drop by the capillary attraction of its generation, perhaps this first drop attracts from other liquid of bristle pack on every side with its surface tension.
The present invention comes with the traditional hairbrush difference with tight bristle pack thus.Because known tight bristle pack develops capillary attraction so greatly, that is, stop from the beginning drop to form.This corresponding to the known hairbrush of prior art based on target, they usually should be tried one's best and to implement with dripping.
Still suitable at this, can not stipulate general formula, the spatial volume in drop space must be much under each concrete condition.On the contrary in this regulation like this, namely, the spatial volume in drop space should depend on that the viscosity of bristle density, bristle diameter, bristle lengths, liquid to be applied and surface tension determine by Specialty Experiment for each concrete condition, perhaps again under the ancillary method of sample printer (rapid prototyping RapidPrototyping) determine.Remembeing above-mentioned explaining the situation down, need not excessive cost and just can realize.
Aforementioned embodiments can further develop as far as possible, namely, although the volume in drop space can be selected so greatly, namely, form last drop, yet also can so select simultaneously littlely, namely, before drop (in bristle pack situation hairbrush, that stop, that dangle in the space together with drop of pointing to straight down, its drippage stage finishes) self drippage, it can be kept 15 seconds by bristle pack at least, be more preferably at least 30 seconds, according to ideal style at least 150 seconds, that is, there is not at first Surface Contact with drop to be applied at drop or bristle.
Central area without bristles preferably has bottom surface without bristles, and described bottom surface is equivalent to one of them border bristle at least 3 times of the cross-sectional area of its root area, perhaps at least 3.5 times, better at least 4.5 times, is in the ideal case even at least 5.5 times.Yet at this according to ideal style, the bottom surface without bristles of central area without bristles has a bottom surface, described bottom surface is equivalent to 15 times of the maximums of the cross-sectional area of one of them border bristle, be more preferably maximum 12.5 times (at its root area, above possible rounding, each border bristle utilizes this rounding to transit to bristle supports).Otherwise, the liquid measure of storing in central area without bristles is tended to scatter within bristle pack, rather than most of in central area without bristles or belonging to and keep " dangling " storage in its drop space and may discharge targetedly thus, for example therein the border bristle by with smear the place and contact and move.Area of bristles above this conclusive root area begins near rounding, bristle utilize this rounding transition to enter bristle supports.At this, preferably roughly Rotational Symmetry, especially approximate circle are annular in bottom surface without bristles.The bottom surface of central area without bristles preferably is interpreted as such surface, and it has imaginary annulus, and this annulus so is plotted in the bristle of border, that is, this imagination annulus is at a radially inner side contacts border bristle of border bristle.
Regulation in another preferred embodiment, the far-end of the bristle of inner region (that is, away from hairbrush handle) end nipple is for the distal end of the bristle of exterior domain.This design of bristle helps the drop in the bristle pack central area to form, and also helps under normal conditions drop to remain in the central area.
The distal end of border bristle preferably protrudes from the distal end of the every other bristle of bristle pack.This in most of the cases forms drop or keeps drop all to produce Beneficial Effect.Especially thus when for the first time continuing to smear thereon Surface Contact with liquid, produce very active influence to discharging drop.Long border bristle with drop or at least the major part of drop remain on therebetween.In case the distal end that protrudes from the residue bristle pack of one or more border bristle is run into the surface and when being out of shape, is just discharged drop at hairbrush at the latest.Only need very little power, this is because only must " operation " one or more border bristle that isolates to a certain extent in its distal end zone for this reason.
Stipulate that in a favourable improved procedure far-end of bristle pack is designed to cone shape tip, so preferred, namely, the imaginary surface that stretches along the far-end bristle ends generally roughly is the conical surface with sharp angle α as enveloping surface, wherein, and 35 °≤α≤55 °.
Drop forms and requires the bristle pack end towards this centering of bristle pack central area.
According to advantageous manner, border bristle form a line (preferably along circumference), and by the border bristle form be listed in its away from the side in drop space by another bristle column wrap at least, the bristle of described another bristle row is each other by larger (the maximum spacing Ab that keeps each other with the border bristle of two direct neighbors
MaxCompare) the bristle spacing separate.
An important aspect of the invention is, uses hairbrush of the present invention and smears water aqueous cosmetics and/or medicine to the skin of eyelid.There is the demand that stimulates the eyelashes vegetative activity in the practice.For realizing this purpose, must affect in a suitable manner medium or stimulant and be applied near on the eyelid of eyelashes root (the preferably especially upper eyelid) parts of skin.Corresponding medium or list the cosmetic field of high value in or listed pharmaceutical field in, and very expensive in the mill.Original only permission of corresponding effective medium smeared very frugally in addition, and this is because within the eye or the surplus that distributes around the circumference of eyes counter productive that may occur not expect.
It is very disadvantageous utilizing smearing that the help of very thin suction pipe carries out advising up to now.Mode is smeared this medium (medium is through eyelashes root or adjacent parts of skin) that critical defect is arranged with (yet up to the present not yet suggestion) that can expect in theory in the help that utilizes " classical mascara brush ", namely, especially the immersion by the relatively large mascara brush of volume has consumed a large amount of media, there are the not controllably danger of drippage of major part in this external smearing in the process, medium.
Claimed quantitative hairbrush has overcome these difficulties and shortcoming according to proposing also in the invention application scope of the invention.This quantitative hairbrush can roughly have been stored the medium amount that truly needs on the place of smearing for realizing in the drop space that this purpose provides specially at it.The amount of existence in the drop space can controllably be sent again.This is particularly useful for, and is these bristles around the bristle in drop space, and they longitudinally observe outwards outstanding farthest, thereby protrudes from other bristles of hair brush area.
Application of the present invention is preferred for smearing the medium with thin concentration, such as it following being described in more detail.
Correspondingly, applicator system also is theme of the present invention, it comprises according to the described hairbrush of one of aforementioned claim and the medium that will smear, be preferably eyelash growing serum, its surface tension OBFS is less than the surface tension of pure water, wherein, brush amount and/or the mode and/or on the one hand for bristle lengths and be so harmonious for the parameter that determines media flow characteristic or drop characteristics on the other hand of being arranged opposite to each other, that is, bristle pack can (the preferred overwhelming majority or roughly) keep the medium of storing predetermined amount and medium can be sent again again when contact parts of skin to be processed in its drop space.
Hairbrush preferably has 6 to 12 border bristles, and they are around the drop space and limit thus the drop space.
According to ideal style, the border bristle has bristle lengths LB, wherein, and 2.75mm≤LB≤5.5mm.
Being proved preferably, bristle, is the border bristle according to ideal style at least, in the root area (top that begins near rounding, bristle utilizes described rounding transition to enter bristle supports) have a bristle root diameter (RD) DF, wherein, DF≤0.06mm is perhaps according to ideal style DF≤0.04mm.
Bristle pack preferably is circular generally, perhaps roughly is circular, and comprises at least 30～90 bristles in this integral body, is more preferably 50～70 bristles.
The medium of smearing preferably has a surface tension OBFS in 20 ℃ of situations, wherein, 15mN/m≤OBFS≤60mN/m is that 20mN/m≤OBFS≤40mN/m(utilizes so-called " capillary effect " or measured according to the method work, common on market surface tension measuring instrument according to ideal style).
The medium of smearing preferably has the proportion of 0.6～1.5g/ml, according to ideal style even only have the proportion (corresponding record) of 0.6～0.9g/ml in the time of 20 ℃.
The medium of smearing preferably has the viscosity of about 1mPas～about 100mPas (under indivedual conditions in the time of 20 ℃, up to 150mPas, not preferred), utilize common viscosimeter according to ideal style in that the 50mPas(of about 1mPas～approximately is corresponding, preferably Engler viscometer records).Thereby the medium that will smear is thin.

The innermost bristle row in interior group of zone 4 also are made of the row 10 of described border bristle, and described border bristle has surrounded out drop space 11, and this drop space 11 illustrates by imaginary solid black lines.Outwards observe diametrically, be adjacent exist in the middle of bristle row 12, its average diameter is preferred not obviously less than the average diameter of (maximum is about 15%) border bristle 10.The bristle spacing of bristles preferably approximately is equivalent to the bristle spacing (maximum be about+15%) of border bristle in the middle of two of direct neighbor.Radially outwards observe, also have outer bristle row 13 adjacent with bristle row 12, outer bristle row 13 consist of interior area of bristles 4 with respect to the border of outer area of bristles 3, and its diameter is compared preferably little about 50%(± 10% with the diameter of border bristle 10).Preferably, the bristle of the direct neighbor of these bristle row has a bristle spacing, and this bristle spacing equals the twice of the bristle root diameter (RD) of this bristle at least.
To specific embodiment shown in Figure 16, BDA/BDI is nearly greater than value 1.5 at Figure 12.
Use hairbrush of the present invention can realize the permutation operational feasibility.
The Reusability of so not only can packing into packing also can be enclosed in the favourable non-returnable container in health aspect (for example being similar to the common liquid eyeliner in market).Applicator of the present invention may be implemented as applicator in bulk, the infiltration of this applicator in bulk is by dripping or spray into (by the delivered inside central outlets the bristle supports bottom surface) from recorder jar, by the immersion liquid storage bottle or by picking to implement from separate carrier (before dripping thereon).
Under disposable operating position, can realize unit dose package according to advantageous manner, the liquid that it comprises applicator and is used for using.
Hairbrush of the present invention is especially having larger advantage aspect the pharmaceutics liquid, this be because this obtain accurately can be quantitative (scope+/-0.01ml), it also can obtain according to the present invention at dexterous design aspect.Can quantitatively open accurately with respect to the present used competitive new application of other quantitative system, guaranteed can not to waste expensive effective liquid, thus hairbrush utilization/unnecessary amount is inappropriate up to now because it exists not in bristle pack.
In cosmetics, picking the required amount of acquisition expectation dressing effect with limiting mode is favourable equally.
The bristle of the injection molded of the present invention's regulation demonstrates obvious advantage.
(length, diameter, locate, lay density) can accurately be adjusted in the injection molded bristle because all important bristle parameters, so can realize such hairbrush, that is, this hairbrush can be realized and will be applied to skin, hair or hair line (minimum 80% fully by its liquid feed that picks; Preferred 90% to 95%).In addition, injection molded allows the embodiment of soft bristle, does not have burr, edge and most advanced and sophisticated to avoid injury.The latter is often really not so in the bristle of being made by the long filament of cutting.The bristle of injection molded allows point-device smearing, and can not occur because unintentionally bending and the hairbrush hair (Pinselhaar) of projection.Do not have the cavity/die cavity that helps the breedings such as bacterium with the bristle pack of bristle supports bottom surface integral type injection molded.
In addition, the hairbrush with injection molded bristle also has following obvious advantage: wetted area integral body can be made by unique material, has guaranteed that for it reaction of any mode can not occur with the active ingredient of wanting coating liquid this material.Especially the adhesive that does not need fasten bristles, it is very important with regard to the reaction that occurs not expecting.
In addition, the bristle of this injection molded is compared with common group that is made by conventional bristles and is easier to aseptic manufacturing.Because this is so heated plastic material to degree in the injection molded process, so that it is aseptic, thereby only need to make it no longer to be subjected to outside recontamination (clean room's technology) behind the injection molded.
In addition, injection molded allows to set other advantageous feature of bristle.Can add very simply like this bactericidal additive (for example silver ion), it is so that bristle originally has antibiotic property in broad range.
The profile that has in addition respective handling by additive and/or manufacturing
Can generate the hydrophilic or hydrophobic property of bristle, this profile is formed on by in the frosting of its shaping and facilitate required effect.
Round brush is preferred, however according to the inventive example as also making oval hairbrush.
Generally speaking, all right brief summary of the preferred embodiment for the present invention is as follows:
The a small amount of bristle of nuclear in the core surrounded by a ring, and described ring is made of many bristles (they outwards may become more very thin), perhaps examines core or the narrowest nuclear core zone is without bristles.
Quantitative corresponding to what will smear by the spatial content that outer group of zone limits.The liquid of smearing forms the drop that is positioned in the middle of the applicator based on its surface tension, this drop be by around bristle keep.
When hairbrush or when being positioned at wherein drop contact skin/hair/hair line, drop is by bristle motion and slightly strut and separate with hairbrush fully.
The liquid profit can further distribute with the outer surface (if needs) of applicator, and joins pending surface.
Consider it should be noted that foregoing description for so-called " bristle pack with part quantitative correlation " for standard, that is, for such part of the bristle pack of all existence: it has determined the corresponding size that is applied to the lip-deep drop of tape handling.In addition, with regard to quantitatively, fully also can there be other additional bristles in the substantially inessential bristle pack fringe region, they do not satisfy up to now the set-up mode for the bristle appointment, for example because these bristles are outstanding in side direction, transverse to wanting with regard to quantitatively overstating and then to the bristle longitudinal axis of the important bristle of the present invention.
In the application's scope, also additional and ask for protection a kind of like this hairbrush independently, this hairbrush is described by following characteristics, equally also illustrate by accompanying drawing, and and nonessential other claims of quoting:
A kind of hairbrush for quantitatively smearing, it has the bristle of injection molded, their integral types or form fit ground injection molded are on the bristle supports bottom surface, wherein, group has border bristle 10, and border bristle 10 directly comes around the scope that limits spatial volume roughly without bristles and with the boundary of residue bristle pack at the center 7 of this group.At this, spatial volume preferably consists of drop space 11, can gather a certain amount of liquid to be applied in the drop space 11, this amount is so big, that is, when contact surface to be processed, just caused the overwhelming majority that preferably suddenly discharges in the droplet-like liquid to be applied.
Self-evident, this hairbrush also can have other features, for example its in the application's claim, describe or above-mentioned explanation in discuss.
Figure 17 to Figure 19 illustrates the 4th claimed embodiment of this alternative.
All had before stated the bristle pack that content all is applicable to this embodiment for other embodiment, difference is forcibly not distinguish between group zone (bristle density is higher than the bristle density in the interior group of zone that is surrounded by outer group of zone therein) and interior group of zone outside herein.Yet, as long as when again having its bristle than more very thin outer group regional 3 of the bristle in interior group of zone 4 when more accurate observe, this embodiment just is equivalent to previous embodiment.
This is slightly larger than the diameter of radially outer bristle because be positioned at inner bristle, referring to Figure 19.
Importantly, there is fully central area without bristles herein.This central area is divided with the residue hair brush area by six border bristles 10 that preferably distribute along circumference and is come, referring to Figure 19.By this way and method, in bristle pack, also obtain drop space 11 in the heart, utilize its help can store the medium to be applied of the amount of determining.At this, the border bristle 10 of delimiting 11 boundary lines, drop space is long brush hairs of hair brush area, thereby can discharge the medium of storing by following manner: the border bristle that protrudes from the bristle pack remainder contacts surface to be applied, and in this motion.Again explicitly point out, all above-mentioned parameters (they determine the size in drop space) that are used for other embodiment also are applicable to this embodiment.
Be more clearly visible in conjunction with Figure 17, hairbrush also can have particularity under this embodiment meaning, that is, it is multicompartment formula injection molded.For realizing this purpose, support cylindrical by difference or that tapering part forms is injection molding shaping.At far-end (that is, on the end away from handle), serve as the cylindrical of bristle supports 1 or tapering part injection molded thereon, the bristle preferred parallel protrudes from bristle supports 1 in longitudinal axis.
Figure 20 to Figure 22 illustrates the 5th embodiment, and it roughly is equivalent to aforementioned the 4th embodiment, and unique difference is, in this embodiment, and the preferred one pack system injection molded of hairbrush, and slightly different in originally bristle supports part there design of hairbrush zone.Yet this bristle pack is corresponding to the 4th embodiment, thereby the described content in there is applicable equally therewith.
