ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an applicator, of the make-up applicator type, particularly a single-dose applicator, which the user may throw away after use. Generally, this applicator is in the form of a flat support formed by a flexible sheet made from a porous, absorbent material on which a thin layer of a slakable make-up product is deposited. Among the make-up products that may be used within the scope of the invention, examples foundations, eyeshadows, rouges, blushers and similar products.
2. Description of the Background
A make-up powder sample is known, presented in the form of an advertising support for a range of shades. This support comprises a rigid cardboard sheet on which several zones are covered with a fine layer of make-up powder in different colors, which the user may sample, for example with her finger, in order to apply the powder of the desired tint to her face, by transfer. This method of applying make-up has the disadvantage that the user's fingers are frequently soiled and have to be cleaned after application. Moreover, it is difficult to obtain homogeneous spreading of the powder using one's fingers, particularly when a relatively large area has to be made up, which is the case, in particular, when the product is a foundation.
U.S. Pat. No. 1,836,833 describes an applicator which may be disposed after use, consisting of a flat member of which a first face is impregnated with product, a second face, arranged on the back, including a layer which is impermeable to the product, protecting the user's fingers against soiling by the product. However, this arrangement does not provide protection for the fingers when they come into contact with the first face which is impregnated with product.
SUMMARY OF THE INVENTION
It is thus one of the objects of the present invention to provide an applicator, of the make-up applicator type, which does not have the disadvantages described above.
It is another object of the invention to provide an applicator which is disposable, which is advantageous both economically and ecologically.
It is another object of the invention to provide an applicator which avoids soiling of the user's fingers by the product during application.
The objects of the present invention, and others, may be accomplished with an applicator, particularly a disposable make-up applicator, including at least one layer of a porous, flexible material, of which at least one part of a first face is impregnated with at least one slakable make-up product, a second face, opposite the first, being covered with an impermeable film. According to the invention, the first face has at least one peripheral portion zone, which is not impregnated with the make-up product, serving as a zone for gripping the applicator and/or a zone for shading off the product applied by the user.
The applicator according to the invention is intended to be transported in the user's handbag or packaged in an individual protective sachet of small volume and may be used to refresh make-up during the day, particularly when travelling. According to another aspect of the invention, a range of applicators of different shades may be used as a tester which the user tries out at the point of sale before deciding to select one or other shade of make-up product packaged in multi-dose form.
On account of its small thickness, an applicator of this type may also be inserted, as a sample, into the advertising pages of women's publications.
According to yet another aspect of the invention, a plurality of applicators according to the invention may be packaged in an appropriate dispensing device to be placed on the user's make-up table.
The applicator of the present invention may be manufactured industrially at a very advantageous cost. It may thus be produced on a conventional printing machine, for example by means of screen process printing. The applicator of the invention offers the advantage that it can be manufactured from biodegradable materials and, from this standpoint, is of significant ecological interest.
A more complete appreciation of the invention and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description, in conjunction with the Figures described below.
