Description

FIELD OF THE INVENTION

The present invention relates to a make-up product.
In particular, it relates to a multi-colour make-up product for the face, eyes, lips, cheeks, etc. such as a foundation, primer, eye shadow, lipstick, lip gloss, blush, mascara, eyeliner, etc.

PRIOR ART

As known, some cosmetic products for make-up are marketed in the form of fluid, liquid or semi-liquid products. The use in that form is rather inconvenient as it is difficult to take the product and apply it without waste.
For some time, in order to improve usability and ease of use, these products have been marketed in containers that house a sponge soaked with the relative make-up product.
The use of the sponge makes the operation of taking the fluid product much easier and can minimise waste associated with the make-up operation.
US 2010/065576 discloses a device for retaining and dispensing porous absorbent pads and US 5 024 325 discloses a dispensing package for dispensing discrete portions of vaporizable material in the form of prewetted absorbent pads.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a make-up product which is improved compared to the prior art, by providing at least two distinct fluids make-up products within the same container.
This and other objects are achieved by a make-up product according to the technical teachings of the appended claims.

DETAILED DESCRIPTION OF THE INVENTION

With reference to the above figures, a make-up product is shown, globally denoted by reference numeral 1.
The make-up product 1 according to the present invention comprises a container provided with a base 2, usually made of plastic material or other materials suitable for the purpose, to which a cover 5 is associated. Advantageously, cover 5 can be hinged at the base so that, by opening the latter, the products present on base 2 or therein may be accessed.
Of course, cover 5 may be associated to the base in a different manner and for example, may be slidable with respect to the latter or hinged so as to rotate along an axis perpendicular thereto.
Depending on the type of make-up fluids housed by base 2, the cover may be provided or not with seals that isolate the interior of the container from the outside environment and preserve the cosmetic product.
The base is be constrained to at least a first 3 and a second 4 make-up element through appropriate constraining means 8 (fig. 4). As seen in figure 1, a third make-up element 5 is also provided, totally similar to the first two. In the configuration shown, the constraining means 8 may comprise simple adhesive for cosmetic use, but they may also be of different types depending on the needs.
The first make-up element 3 comprises a first sponge 3A soaked with a first make-up fluid 3B. Also the second make-up element 4 comprises a second sponge 4A soaked with a second make-up fluid 4B, which is however different from the first one. The same applies to the third make-up element 5, which provides a third sponge 5A also soaked in a third make-up fluid 5B, which may be different from the first two.

The formula with which the make- up fluid 3B, 4B is made has a low dynamic viscosity, such as between 1000 and 10,000 cPs. It is designed not to create differences in the amount of product contained in the sponge and in particular for: preventing colour variations within and along the surface of the sponge,
facilitating the absorption in the sponge,
being optimally retained by the sponge which, if handled or moved, should not release product outside.

The formula of the make-up fluid can meet the performance standards of the specific cosmetic product for make-up and for example must minimise migration if it is s a lipstick, must minimise unevenness if it is a foundation, must minimise the formation of lines and migrations if it is an eye shadow, etc.
The formula of the make- up fluid 3B, 4B may need or not of an air-tight container and therefore may comprise or not some substances known in the cosmetic field as "volatile".
Possible examples of formulation of make- up fluid 3B, 4B are those shown below:

Example 1 of (anhydrous) mixture which may comprise:

a) Anhydrous phase 75-90% (comprising film forming polymers 0-10%, rheological additives 30-50%, preferably 30-40%, emollient oils 30-50%, volatile solvents from 0 to 30%, pure pigments 0-10%).
b) Texturising agents 5- 10%

Example of (aqueous) mixture 2 which may comprise:

a) Aqueous phase 50-90% (water 50-90%; wetting agents 1-5%; rheological additives 0.1-2%)
b) Pure pigments and/or beads 0-30%, preferably 1-20%
c) Emollient oils 1- 20%
d) Solubilising agents 0.01- 10%

As can be seen, at least the first 3 and the second 4 make-up element are mutually alongside on base 2; in particular, the second make-up element is arranged between the first 3 and the third 5 make-up element.
From the analysis of figure 2 but even better from the analysis of figure 4, it is seen that at least the first sponge 3A and the second sponge 4A have at least one mutual contact side 7, in rest configuration or at least when one of them is subjected to a pressure in an area adjacent to the contact side 7.
At least one sponge at at least said contact side 7, has a coating 6 intended to obstruct the migration of the fluid astride said contact side 7.
Coating 6 is particularly important in cosmetics, since the migration of a make-up fluid present on a sponge to the adjacent sponge, impregnated with a make-up fluid different even in one characteristic only (such as the colour) must be prevented or minimised.
A particularly advantageous configuration is clearly visible in figure 4, where each of the sponges 3A, 4A has its own coating 6 at said contact side 7.
As an example, coating 6 may consist of a layer of insulating polymeric and non-polymeric resins, or of insulating filming polymers applied, for example by brush, spray, by partial dipping, by contact or other suitable method, on one or more sides (even on all sides) of the sponge or sponges.
The coating may also be made of a transparent or non-transparent polymeric elastomer film, or of an insulating plastic material, for example glued or constrained in another suitable manner to the sponge. A technique that can be used can be the one known as in-moulding, wherein the film is applied to the intended mould before forming the sponge; the film attaches to the sponge during the expansion step of the synthetic resin with which the sponge itself is produced.
The coating may also simply consist of an area or part of the sponge with different physical characteristics than other areas of the same (such as a smaller or no porosity, or a different density).
Coating 6 may also be formed by a surface treatment of the vulcanisation type made directly on the sponge(s), or outer coating with insulating nano-particles.
As already mentioned above, the make-up elements may be stably fixed to base 2 or removable constraining means 8 may be provided, thus allowing to remove and replace at least one of the make- up elements 3, 4 into position for impregnating again the sponge with the relative make-up fluid.
The removable means 8 may for example be of plastic material, snapping, directly associated to a portion of the sponge, or they may simply provide interference joints with suitably shaped portions of the base, or associated with it.
Advantageously, the sponge(s) is/are synthetic and can be made for example of: urethane or polyurethane resin; open-cell and partly closed foamed polyurethane resins; closed cell foamed polyethylene resins; as a "mousse", also known as foamed synthetic rubbers or elastomeric foams.
Particularly suitable for the present application are sponges of open cell polyurethane foam with a density ranging from 60 to 90 kg/m², preferably of 75 kg/m ^{2 ±}5%, and with a resistance to compression at 40%, ranging from 13,5 to 17 kPa, preferably equal to 14 ^± 5% (ISO 3386 standard).
According to a possible variant, at least one of the make-up elements comprises a bottom 9 inside of which the relative sponge is partially housed. In this case, the constraining means 8, which may be of the types described above, may be provided between bottom 9 and base 2 itself.
As is seen in figure 5, the height of the edge of the bottom(s) 9 is lower than the height of the sponge housed therein.
The embodiment described above is provided with only three make-up elements, but of course a desired number thereof may be provided, also depending on the type of make-up product to be implemented. All the make-up elements will be substantially similar to those described above.
To use the make-up product 1, a user may at first remove the cover 5. In this condition a dispensing surface (the upper surface in fig.2) of the make-up elements 3,4 fixed to the base 2 is made directly accessible to the user. It is to be noted that during the normal use of the make-up product, i.e. when used during a make-up procedure, the make-up elements are stably fixed to the base. The make-up elements, as described above in some embodiments, may be removed from the base only for maintenance reasons or to refill them with other make-up fluid.
In particular, during the use, the dispensing surfaces of the make-up elements (that when the cover is in position, are facing the cover) may be accessed by the user while remaining fixed to the base.
In this condition the user may put a finger (or an applicator) on the dispensing surface of the make-up element of the desired colour (or with the desired make-up fluid).
At the same time, the base can be held with a hand in order to stabilize it, or may be lied on a surface that supports and stabilizes it. For this reason, the base is rigid. This means that the base is built with a rigid material. In this contest a rigid material may be metal or plastic, of the type usually employed for casings of make-up products. In particular, that kind of rigid materials should maintain their shape when firmly grasped by an operator using the make-up product.
The pressure of the finger (or of the applicator) squeezes the sponge thereby dispensing a needed quantity of make-up fluid that may then be used to perform make-up procedure.
It is noted that all the percentages given in the present description are to be understood by weight. The other measurements are instead carried out at 25 degrees centigrade.
Various embodiments of the invention have been described but others may be conceived using the same innovative concept.
