Description

FIELD OF THE INVENTION

The present invention relates to a nomadic, miniaturized and automated distribution system, making it possible to recover, process, reproduce and distribute a colored product having a target color, chosen to measure, by a user. The system is refillable in raw material and reusable as desired. The system also allows very precise dosing and therefore the delivery of a necessary quantity of colored product for application by a user, on themselves or another support.

The present invention also relates to a method of dispensing a colored product having a target color using a dispensing system according to the present invention.

The dispensing system of the present invention can be used in applications requiring the dispensing of a colored product having a target color.

STATE OF THE TECHNIQUE

In researching and purchasing their cosmetic products, consumers today are more and more demanding and are sensitive to different criteria when choosing their new product, which must, for example, be respectful of the environment and skin of its user.

To this end, players in the cosmetic products sector must today offer a range of products that meet these criteria while offering a wide choice to the consumer, allowing them to find the shades that correspond to their skin or their desires. .

• Des produits non adaptés avec des écrins en plastique (première source de pollution) et des contenants non optimisés (30% de la matière est perdue).
• Une surconsommation aux conséquences environnementales importantes (un milliard de rouges à lèvres achetés et donc jetés par an par exemple).

Despite some progress made in this area, overall, players in the cosmetics sector are still struggling to make this shift. The cosmetics sector is, for example, the second most polluting in France, mainly due to:

• Unsuitable products with plastic boxes (primary source of pollution) and unoptimized containers (30% of the material is lost).
• Overconsumption with significant environmental consequences (one billion lipsticks purchased and therefore thrown away per year for example).

We also note that cosmetic products often target a certain type of skin, particularly Caucasian, neglecting skin with high or low melanin.

There is therefore a need to offer a product offering its user a unique and personalized experience, without distinction, while being eco-responsible, that is to say respectful of the skin of its user and the environment, and by limiting overconsumption and therefore waste and loss of materials.

For example, we know of lipsticks whose packaging is unique and can be refilled with grapes sold in the form of refills; this is particularly the case for Rouge G ^® lipsticks from Guerlain ^® , or even lipstick from La Bouche Rouge ^® . However, the purchase of refills of different colors remains necessary with this type of system, in the event that the user wishes to change color.

Dispensers are also known for delivering a cosmetic composition of variable color. Requirement FR3029088 concerns for example a distribution system, in particular for a makeup product, making it possible to personalize the product used by a consumer. The latter provides a distribution system consisting of a housing and at least two compartments received in the housing, each compartment being provided with a movable piston and a distribution nozzle through which the product exits. base. The mixture is generated from the different basic products, these basic products can have different colors, such that the color, shade or even the coverage of the mixture can be personalized, the mixture being collected in a cup incorporating a static mixer.

Requirement WO2014043018 discloses a tailor-made coloring system, in particular a cosmetic product having a color matched to the skin color of its user. The process, including a skin color analysis step using a spectrophotometer and a camera, sends mixing and dosing instructions to a remote formulation machine that mixes a series of base products and dispenses it into a container.

However, several disadvantages result from these systems. First, they offer a mixture recovery device forcing the user to use their finger or another means of external application. In addition, the dosing system does not always allow the delivery of a single dose so that, if the quantity distributed is excessive, this results in a loss of product and conversely, if the quantity distributed is not sufficient, the process must be repeated, again resulting in product loss. The user still has to go to points of sale in order to make their tailor-made mixture, or wait for the delivery of their product.

The present invention aims to meet this need by proposing a nomadic, miniaturized and automated distribution system, making it possible to recover, process, reproduce and distribute a colored product having a target color, chosen to measure by a user, the system distribution system is refillable in raw material and reusable at will, thus reducing waste, the system of the invention also allows very precise dosing and therefore the delivery of a quantity necessary for an application without loss of product.
