Patent Application
20170203265
This invention relates to a device for the preparation of a cosmetic product from a cartridge whether it is in the form of a cream, an emulsion, a lotion. The invention also covers the suitable cartridge.
The cosmetic products are used more and more, with the appearance often being increasingly elaborate for life in society.
In addition, the cosmetic products also make it possible to compensate for and to limit the impacts of stress, pollution, the effects of sunlight, and the effects of time.
There are a large number of products that have the target effectiveness, and the market has become extremely large, no longer being limited to women but in contrast encompassing adolescents and men.
In general, these cosmetic products have plant origins but increasingly marine origins, and are even obtained from exotic sources. The consumers have also noticed that certain products, poorly designed and manufactured by unscrupulous companies, contained allergenic products, toxic products, and at least ineffective products.
In addition, the industrial products are produced in advance and should have aspects and textures that are perfect, constant, and reproducible.
It therefore must be necessary to add, in addition to cosmetic active ingredients, products for preservation and/or stabilization.
In addition, the consumers increasingly seek to have products that totally correspond to them.
The current tendency is therefore increasingly to have recourse to “home-made” and to “custom-made.”
The cosmetics are also subject thereto.
Nevertheless, the industrial methods are complex and require production lines of great complexity that it is impossible to reproduce on a very small scale for domestic uses, by private individuals.
Manufacturers have much greater constraints than private individuals, in particular the perfect reproducibility for using a product of identical presentation, regardless of the site, regardless of the conditions of shipping, preservation, and the time period between the manufacturing and the sell-by or use-by date.
At home, the constraints are fewer because the product is already on site and is not subject to any shipping.
The product that is obtained must have a good consistency and is not subject to vagaries of significant temperature fluctuations.
The constraints are thereby much less significant.
The necessary adjuvants can be greatly limited.
The advantages are therefore numerous.
The cost is also an important component since the industrial products are finished products in their packaging for sale and use.
The volume that is to be shipped is large.
Likewise, the packaging is only very rarely reusable and reused in cosmetics.
The cosmetic products, marketed by manufacturers, are very numerous to be able to meet the different needs. It is inconceivable to manufacture industrially products on demand, in a volume adapted to the needs of a private individual, with a domestic use.
There are machines of the prior art that make it possible to produce cosmetic compositions—in particular the patent application EP 1 813 335—but it is more a matter of an extraction from compounds contained in a capsule by injecting a pressurized fluid, with this machine being similar to a percolator.
The cosmetic compositions should come in the form of an emulsion, a cream, milk; therefore, it is advisable to be able to offer a cosmetic form and not only to carry out an extraction of active ingredients.
The patent application EP 1 221 419 also describes a first container with a first composition and a second container with a second preparation, connecting means between the two containers to ensure a mixing of the two contents in such a way as to obtain the desired final composition.
The object of this invention is a device that makes it possible to produce preparations of cosmetic products, on demand, by limiting the adjuvants by eliminating constraints associated with shipping and with storage conditions, by eliminating the postage associated most of the time with the shipping of the excipient, often by water, by offering a very fast production that is not subject to any industrial polluting environment.
In addition, the composition can be offered in the form of cartridges and produced on demand.
The cartridges can be preserved with no problem over long periods.
The cost is inevitably lower, and the user also has the pleasure of seeing the manufacturing of the product and contributing to it.
The device for preparing a cosmetic composition is now described in detail according to a particular, nonlimiting, embodiment, relative to the accompanying drawings, drawings in which the various figures show:
This invention therefore has as its object a device for preparing a cosmetic product, in the form of a cream, an emulsion, a lotion, a gel, a suspension, a mask, or an exfoliating scrub, in a first container 10 from a base and at least one excipient, comprising:
