A plurality of radially extending bristles is retained between the wires of the core. The bristles have a diameter of about 0.003 inch to about 0.012 inch and a bristle density of about 7 bristles per turn to about 50 bristles per turn, and more preferably, a bristle density of about 7 bristles per turn to about 25 bristles per turn.

Description

The wire mascara brush of flocking

Technical field

The present invention relates to a kind of brush of putting cosmetics on the skin that is coated with, relate in particular to mascara is coated with the brush of putting on the skin on the eyelashes.

Background technology

Existingly be used for the liquid state cosmetics, for example be used for that mascara is coated with the stranded wire brush of putting on the skin on eyelashes (twisted wire brushes) and be widely known by the people.This class brush is designed to dip in from cosmetics containers to be got and keeps the mascara articles for use, puts on the skin on the eyelashes when the user is coated with mascara when brushing eyelashes then.

Traditional stranded wire brush is by transverse to substantially parallel slightly isolated fine wire shape thing section (lengths) and between these fine wire shape thing sections many separate bristles sections are set and make, and common wire lengths is divided monofilament equally in the midpoint of monofilament section (filament lengths).Most typically be that parallel wire lengths comprises by the single hop wire and bends to the U-shaped structure and two basic leg sections that equate forming.Then these wire lengths are twisted together and form spiral helicine heart spare, make the bristle (bristles) that is arranged between the wire roughly put clamped therein.In the process of stranded and clamping, bristle sections is radially outward opened from heart spare on the either side of the mid point that clamps, so form the normally brush portion branch of the elongated bristle of circular cross section.Usually bristle is made of nylon monofilament.The effect of bristle is to collect mascara and kept mascara from hold-up vessel before mascara being coated with on the eyelashes of putting the user on the skin.Brush is fixed on the bar usually, and this bar is installed on the cap of cosmetics containers or is installed on other the closure member of cosmetics containers.

Known in the fieldly be, being used to form stranding method that cosmetics are coated with the wire of putting brush on the skin often causes bristle in the brush configuration to tend to accompany or follow spiral pattern (helical pattern) in stranded wire core usually, that is to say that the tip with bristle is defined as the spirality distribution thus.60 and the standard mascara brush of seventies design adopt the less bristle of diameter and the quantity of every circle bristle is quite a lot of.

Subsequently, prior art develops into as described in the US 4887622 some and adopts the situation of larger-diameter bristle.This patent disclosure the mascara brush that reduces of a kind of brush amount, the bristle of this mascara brush lacks 35% to 80% than the bristle of traditional mascara brush, and is obviously more much bigger than the bristle diameter of using in the traditional mascara brush simultaneously.It is believed that this can be coated with better puts mascara on the skin and eyelashes are separated better.This patent specifically described bristle diameter be about 0.10 to 0.25 millimeter (mm) [that is, being about 0.004 to 0.010 inch (inch) or 4 to 10 mils (mil)] and spiral each enclose the mascara brush of about 10 to 40 bristles.The design of the mascara brush with larger-diameter fiber further has been discussed in WO 0158309.The disclosure file relates to by more slightly but the mascara brush that very soft monofilament constitutes.Particularly, this application has been described the mascara brush that preferably has every circle 7-14 root bristle.Bristle filaments is restricted to preferably from 0.245mm to 0.319mm (0.010inch is to 0.013inch or 10 to 13mil).The most important thing is that it is quite soft that bristle is defined as, its by have SH meter reading (durometer) between 62 Shore hardness (Shore) D and 82 Shore D, the thermoplastic elastomer (TPE) that most preferably is about 72 Shore D makes.This document limits mascara brush substantially and is made of the DuPont monofilament of sales trademark for " Supersoft "." Supersoft " monofilament has the hardness that duremeter number is 72 Shore D and can be commercially available solid monofilament or three orders (triocular) monofilament with three hollow cavities.

Mascara is coated with when putting on the skin on eyelashes, and the mascara of high viscosity may lump usually.Normally remove the mascara of (combed out) caking as the final step that is coated with the process of putting on the skin.It is believed that stiffening bristle is fit to remove the also very suitable separately eyelashes of caking very much.Certainly, people also think have more sparse bristle crust (open bristle envelope) or brush surface brush, be that the brush that has a lot of or wide gap or space between the bristle, makes brush more resemble comb shape can be finished the function of brushing and separating better.Utilization can not realize this function well with higher bristle density, traditional mascara brush designs with bristle of less diameter.Usually it is believed that the mascara brush with a lot of bristle of soft quantity is suitable for being coated with puts mascara on the skin very much, but not too is suitable for removing caking and eyelashes separately.Otherwise, has brushes that are stiffening, several bristles and be considered to be more suitable in brushing and separate eyelashes, but not too suitable eyelashes are coated with put mascara on the skin.Though can adopt separately brush, that is to say that put on the skin and with brushing firmly with soft brushing, single can being coated with put mascara on the skin to remove the brush of caking again be preferred for every kind of function.

Disclose among the US 5238011 and had the example that the brush of performance was put and brushed in good being coated with on the skin.This Patent publish by having the bristle that the Shore hardness of 20A to 40D (and as mentioned above, traditional bristle has the hardness that duremeter number surpasses 85D usually), 0.10mm are made to the soft material of the interior big diameter of 0.35mm (0.004inch to 0.014inch or 4 to 14mil) scope.The diameter of bristle should be enough big, and is too high to prevent degree of crook.The brushing tool of Huo Deing has degree of crook identical with conventional softer brush or pliability like this.

Yet the user of mascara can feel the bristle stiffness that is caused by this major diameter bristle.For mascara brush, existing scheme can not provide have whole desired characters in conjunction with, promptly have a good brush of brushing the high mascara useful load under effect and the imperceptible bristle of the consumer situation really up to the mark.

Therefore, it is desirable to, mascara brush has stranded wire to be done and outward extending bristle, this brushing tool has the surface area that is used to carry mascara of increase, its uniformly mode dip in and get cosmetics, and can dip in the mascara of getting and carry appropriate amount under the situation about stretching into again in the mascara reservoir repeatedly will not brushing, and brush also have the good eyelashes of brushing and make and stretch the effect of (lengthening) under the situation that does not cause the sensation that bristle is really up to the mark.
