The present invention relates to a process for the preparation of a poured cosmetic product with a superficial relief.
The term “poured cosmetic product” indicates a product formed by a mixture which is taken to the melting temperature so as to change from a solid state to a liquid state and to allow its dosed introduction by “pouring” within appropriate moulds, where it subsequently solidifies in order to form a solid tablet of different shapes and sizes, which is finally extracted from the mould and overturned in the final container.
Cosmetic products obtained in this manner have a lower surface, which will hereafter be designated as “bottom surface”, and an upper surface, which will hereafter be designated as “decorative surface”, which may either be smooth or have reliefs.
Currently, for the production of a poured cosmetic product with superficial reliefs, a mould is used featuring a shaping complementary to the reliefs of the decorative surface of the cosmetic product. A thick grid having protruding edges with respect to the edges of the mould is applied internally at the mouth of the mould.
While the cosmetic product is produced, the mould is initially filled, through the grid, with a molten mixture of cosmetic product, until the level of the edge of the grid is reached.
During the following solidification, the mixture becomes integral with the grid thus forming the cosmetic product, temporarily placed in an inverted position: the bottom surface is in an overlaid position protruding from the edge of the grid, and the decorative surface is in an underlaid position enclosed within the mould.
The cosmetic product is at last placed in the final container by using handling equipment, which clamps the edges, raises, overtures and introduces the grid with the corresponding cosmetic product within the final container.
In this manner, the grid becomes a part of the marketed product, with a subsequent additional cost and a waist of space and weight; moreover, much of the cosmetic product remains unused, trapped in the interstices of the grid.
It is the object of the present invention to overcome the above mentioned drawbacks.
According to the invention, such an object is achieved by a process for the preparation of a poured cosmetic product, said cosmetic product comprising a decorative surface comprising reliefs and an essentially flat bottom surface, characterised in that it comprises a first step of dosing a liquid mixture of said cosmetic product within a shaped mould, a second step of solidifying said mixture within said mould in order to form said cosmetic product, a third step of extracting said cosmetic product from said mould by exerting perpendicular forces on said bottom surface, a fourth step of overturning said cosmetic product within a final container.
The extraction means may be sucking means, adhesion means or other means depending on the embodiment.
The surface on which the extraction forces are exerted may be formed by the bottom surface of the product itself, or by the outer surface of a small plate provided with holes or of a small cup also provided with holes, or by a wax layer on the bottom surface of the solidified cosmetic product.
The use of a traditional grid and the corresponding drawbacks may be avoided in virtue of the forces applied perpendicularly to the support surface providing a wide application area.
These and other features of the present invention will become more apparent from the following detailed description of embodiments thereof, shown by way of no limitation in the accompanying drawings, in which:
The sucker applies a vertical force, perpendicular to the bottom surface 1B which is flat and smooth, has a relatively large size and easily allows the grip by the sucker 4, which easily extracts the cosmetic product 1.
There is provided the introduction of the cosmetic product 1 within a final container 5 to which it is adhered by sticking or by contact with a heat source.
At the end of the process, the cosmetic product 1 is arranged within the final container 5 with the overhanging decorative surface 1A and the support surface 1B.
A second embodiment is partially shown in
The mixture 7 solidifies during the second step (not shown) and adheres to the small plate 6 so as to become integral therewith.
The following steps are the same as those in the first embodiment. It should be noted that the small plate 6 represents an ideal support for the sticking to the final container 5, as it is rigid.
A third embodiment of the present invention, shown in.
A fourth embodiment, shown in
During the first step (
At the end of this second step, a mixture of synthetic waxes 11 is overlaid to the solidified mixture 7 (
At the end of this process, the cosmetic product 1 is introduced and fixed within the final container 5.
In all of the embodiments the mould 2 may be made of silicone, metal or different material.
Finally, a composite cosmetic product may also be produced by the juxtaposition of a tablet according to the invention with a similar tablet having a different composition or with a different tablet.
