ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the invention
The present invention relates to a powder-dispensing brush for cosmetic use.
2. Description of the prior art
A powder-dispensing brush can advantageously be used to apply a cosmetic powder to the skin, metering the quantity of powder used and applying it homogeneously.
DE 43 40 723 describes a powder-dispensing brush including a powder reservoir, a tuft of hairs secured to said reservoir, in particular by a sleeve, and means for causing said powder to migrate from said reservoir into said tuft.
In the above powder-dispensing brush the tuft of hairs is in fact made of a plurality of groups of hairs and the migration means comprise a plurality of passages communicating with the reservoir and coming out between these groups of hairs.
It is found that, in use, when the tuft of hairs of this brush reaches a certain consistency, the powder has a tendency to remain trapped within the hairs of the brush, and that it is difficult to extract it without shaking the brush vigorously.
The object of the present invention is to avoid these drawbacks.
SUMMARY OF THE INVENTION
The invention achieves the above object with a powder-dispensing brush including a powder reservoir, a tuft of hairs secured to the reservoir, by a sleeve, and means for causing the powder to migrate from the reservoir into the tuft, wherein the tuft includes at least one group of relatively more dense hairs and at least one group of relatively less dense hairs and the migration-causing means include at least one passage communicating with the reservoir and coming out between the groups of relatively more dense hairs and relatively less dense hairs or into the group of relatively less dense hairs.
The above features provide a powder-dispensing brush which tuft includes relatively more dense areas which provide a satisfactory tuft consistency, and relatively less dense areas in which the powder can migrate without difficulty.
It is thereby provided a powder-dispensing brush which tuft is consistent and which doesn't have to be shaked vigorously before each use in order to extract the powder.
According to other preferred features of the powder-dispensing brush of the invention:
the passage extends as far as the interior of the tuft to facilitate expulsion of the powder,
the tuft includes the group of relatively more dense hairs and, at the center thereof, the group of relatively less dense hairs, and the migration-causing means include a plurality of passages disposed in a circle, communicating with the reservoir and coming out between the groups of relatively more dense hairs and relatively less dense hairs,
the passages are formed in a hollow barrel defining with the sleeve a substantially annular groove, the group of relatively more dense hairs being disposed in the groove and the group of relatively less dense hairs being disposed at the center of the barrel,
the migration-causing means include six passages,
the interior of the sleeve is substantially frustoconical,
the sleeve and the migration-causing means are molded in one piece and screwed to the reservoir,
the groups of relatively more dense hairs and relatively less dense hairs have different colors,
the brush includes a shroud adapted to slide on the reservoir to pack the tuft more or less tightly and to protect the tuft.
Other features and advantages of the present invention will become apparent in the light of the following description and the accompanying drawing.
