Definitions

• the present invention relates to a device and a method for dispensing a fluid product on demand, in particular a cosmetic product. It may in particular be a product for the lips such as a lip oil. It also relates to a distribution system comprising such a device.
• On-demand cosmetic product distribution systems allow a user to have a product that meets their current needs rather than depending on a limited choice of products in a predefined range. Such devices make it possible to take given proportions of basic products from tanks which, after mixing, form the product corresponding to the user's needs.
• the basic products are distributed separately and it is up to the user to mix them. This has disadvantages because the user does not always have the appropriate equipment to carry out the mixing. Furthermore, although such devices may be suitable for the distribution of samples of small quantities of products, they are less suitable for the distribution of larger doses. They thus require the user to quickly repeat the operation to have a new dose of products.
• Dispensing devices comprising a circuit making it possible to mix the different basic products to be used in the formulation of the product to be distributed are also known. In addition to the advantage for the user of avoiding having to mix the basic products herself, such devices make it possible to obtain larger doses.
• An aim of the invention is to propose a distribution device which at least partly overcomes the preceding drawbacks.
• the invention relates to a device for dispensing a fluid product on demand, in particular a cosmetic product, said device being configured to allow a mixture of at least two products, called base products, in proportions chosen from information coming from a user to form said product on demand, said device comprising a mixer, configured to ensure mixing of said basic products, said device being configured to supply said mixer separately with said basic products, according to said proportions, and to deliver the product on demand at the outlet of said mixer, said mixer being for single use.
• single use we mean that the mixer 26 is intended to be changed for each new use, that is to say, for each distribution of a new dose of product on demand P, each of said doses being constituted by mixing the basic products in quantities corresponding to said chosen proportions.
• the device is configured so that there is no mixing of the basic products upstream of the mixer, even if they can enter said mixer simultaneously.
• the device according to the invention allows that there remain no portions of circuit in which residues of the dose previous, already mixed, may be present. This ensures that each new dose only contains the desired proportions of basic products, while not reverting to a separate distribution of said basic products. In addition, we avoid having to clean the circuit between each use.
• the mixer is a static mixer; - the mixer includes an endless screw; - said device further comprises an injector, configured to supply the mixer with said basic products; - the injector comprises an inlet orifice and outlet orifice for each of said basic products; - the inlet and outlet ports of the injector are respectively connected by basic product circulation conduits; - the conduits have a reduction in section between the inlet and the outlet; - said injector has an output interface and said mixer has a connection interface, intended to cooperate to be connected to each other; - said output interface has at least two pins, one of said pins presenting at least one of the outputs of the injector and the other or another of said pins presenting at least the other or one of the other outputs of the injector ; - said connection interface has at least two cavities, each of the cavities being configured to respectively accommodate one of said pins so that said basic products open out, in
• the invention also relates to a distribution system comprising a device as described above and a user interface making it possible to determine the proportions of basic products to be taken to obtain the product on demand.

• said device is configured to allow a mixture of at least two products 20a, 20b, 20c, called basic products, according to proportions chosen from information coming from the user to form said product on asks P.
• Said basic products may be any type of fluid and/or powdery product. These are, for example, products intended to be used in the composition of a cosmetic product. These are more particularly, among others, monochromatic, namely, a mixture of a fluid base and a colored pigment.
• the dispensing device can equally allow the mixing of numerous basic products, in particular several monochromatic ones of different color, of one or more basic products making it possible to perfume said product on request, using one or more fragrances, and/or one or more texturizing base products, to give it a particular appearance, notably glittery.
• Said monochromatics are, for example, eight in number. They preferably contain an identical base from one monochromatic to the other.
• said base products advantageously comprise a plurality of monochromatics accompanied by a texturizing base product and a so-called neutral base product.
• Said texturizing base product comprises a fluid base, possibly identical to that of monochromatic products, and a texturizing component, for example glitter.
• Said neutral base product comprises only said fluid base.
• said device is configured so that each new dose of on-demand product P includes either a proportion of texturizing base product, if the on-demand product P must contain a texturizing component according to the user's choices, or the same proportion of neutral base product if the product on request P must not contain a texturizing component according to the user's choices.
• Such a configuration makes it possible to maintain the same overall proportion of monochromatics in each dose and therefore to better control a rendering in terms of color of the product on demand P from one dose to another, whether or not the user wants the dose of said product on demand P distributed includes a texturizing component.
• Said device further comprises, for example, a plurality of reservoirs or cartridges 22 intended to each contain one of said basic products 20a, 20b, 20c.

• each of said cartridges 22 is associated with one of said pumps 24a, 24b, 24c so that one and only one of said pumps 24a, 24b, 24c is used to collect one and only one of said basic products 20a, 20b, 20c.
• They are, for example, of the peristaltic type, which prevents the basic products from coming into contact with moving parts.
• said device comprises a mixer 26, configured to ensure mixing of said basic products 20a, 20b, 20c.
• Said device is further configured to supply said mixer 26 separately with said base product 20a, 20b, 20c, according to said proportions, and to deliver the product on demand P at the outlet of said mixer 26.
• Said mixer 26 is preferably for single use.
• single use we mean that the mixer 26 is intended to be changed with each new use, that is to say, with each distribution of a new dose of product on request P.
• the device is configured so that there is no mixing of the basic products 20a, 20b, 20c upstream of the mixer 26, even if they can enter simultaneously into said mixer 26, from a point of view temporal.
• said basic products 20a, 20b, 20c are therefore not mixed upstream of the mixer 26 and the latter can be completely changed for each new use. This allows us to avoid the presence of residues from a previous dose during the distribution of the next dose, which could harm the appearance and/or the right quantity of product on demand P distributed.
• Said device comprises, for example, a circuit 28 connecting the cartridges 22 to the mixer 26 through the pumps 24a, 24b, 24c.
