Description

The present invention relates to a device for application to a

  support, especially on the skin, hair, or nails of a liquid composition, using a jet of pressurized fluid as a vector of the liquid composition to transfer it to the support. The pressurized fluid can be

  in particular a compressed gas or a liquid composition.

  In the field of make-up of hair, skin or nails, an urgent need is emerging, the need for a device allowing the user to be able to choose the color of her in a simple manner.

  makeup from a palette of different colors.

  It is known to apply a colored substance to a support, causing particles or pigments of said substance to move, from a source containing said substance, to the support, via a jet of pressurized gas, in particular air . Thus, European patent EP 0 462 765, as well as PCT applications, WO 94/12288, WO 97/03757 or WO / 9803269, describe devices making it possible to precisely position a jet of propellant fluid relative to a felt tip, or equivalent, so as to be able to move a given quantity of the colored substance present on the felt, towards the support to be printed. One of these documents mentions the possibility of generating the jet of pressurized fluid by means of an aerosol device or an electric pump. In all these devices, the felt is held in a case, or in an annular element, inside which it is held by a screw. Whenever the user wishes to change color, he must replace the felt with a felt of a different color. These operations, especially when they are repeated many times, are tedious. In addition, there is a great risk that one or more of these felts will be lost between

two uses.

  In other fields of cosmetics, it is also known to use a first composition in combination with a second, said first and

2 2781208

  second composition must, in particular for reasons of stability, be packaged separately. Thus, in the field of sunscreen products, it is known to combine an amino acid solution, in combination with a solution containing di-hydroxyamine (DHA) for the artificial tanning of the skin. In the context of such an application, it may be desirable to be able to offer the user the possibility of choosing from several compositions containing DHA, in different concentrations, depending on the tan she wishes to obtain. It is also the same for the association of a solution of - vitamins or proteolytic enzymes making it possible to peel the skin, with a composition containing salicylic acid, the concentration of which can

  be chosen at will according to the condition of the skin.

  It is therefore one of the objects of the invention to provide an integrated device, allowing the transport by a pressurized fluid, to a support to be treated, of particles of a composition which can be chosen from a plurality of compositions. It is another object of the invention to allow a plurality of different combinations between a first composition under pressure, and another composition, chosen from a palette of different second compositions, said first composition under pressure serving as a vector for transport. of the second on a support, thus realizing an application

combined of the two compositions.

  It is yet another object to make such a device which is simple

  of use, reliable, and which is economical to produce.

  Other objects will appear in the detailed description which follows.

  According to the invention, these objects are achieved by producing a device for the application to a support, of a liquid composition, comprising: a) means for producing a jet of a pressurized fluid through a orifice of exit-; b) N (N> 2) reservoirs coupled to said means, and each containing a liquid composition, each of the reservoirs being equipped with a member of which a first end is disposed in the reservoir and of which a second end emerges out of the reservoir, said member being able to supply said second end with liquid composition; and c) operating means for selectively bringing the outlet orifice opposite any one of the N reservoirs so that said outlet orifice is positioned in the vicinity of said second end of the selected reservoir, said jet being capable of entraining a certain quantity of liquid composition of the selected reservoir, from said corresponding second end and transferring it

on said support.

  Thus, the various compositions, among which the user can choose, are packaged in tanks coupled, via one or more mounting elements, to the element generating the jet of pressurized fluid, the means of manceuvre allowing to appropriately orient the outlet orifice of the source of pressurized fluid, facing the reservoir containing the composition chosen by the user. An integrated, easy device is thus produced

  to use, and economical to make.

  According to a first example, the compositions contained in the reservoirs are liquid compositions, of different colors, which can be used for making up the body, and in particular the hair, nails or skin. The user can thus choose from a palette of colors, the one she wishes to use for this or that part of the body. This palette of "elementary colors", the number of which can be variable, can then be declined in the form of an infinity of nuances, and this without requiring tedious manipulations, simply by changing the relative position of the outlet orifice relative to the tanks. The color composition (s) can (be) applied (in particular) to the skin or the hair, via a stencil, in order to

  precisely define the contours of the application.

  Preferably, said means for producing a jet of a pressurized fluid comprise a container containing said pressurized fluid, and surmounted by a valve which can be actuated by an actuating member. The pressurized fluid can be a compressed gas, in particular air, butane, isobutane or isopropane. The valve can be of the male or female type. It is preferably of the axial sinking type. Such an element, in the form of an aerosol device, offers numerous advantages. It allows in particular to

  produce a jet of sufficient pressure, and reproducible homogeneously.

  -The pressure can vary from 0.25 bar to 5 bar, and preferably from 2 bar to 4 bar.

  Such an element is relatively small in size. Its operation is simple. In addition, the technology used in aerosols, in particular with regard to the configuration of the nozzle which can be advantageously mounted in the outlet orifice, makes it possible to produce jets whose cross section has contours which can be chosen relatively precisely,

  especially in terms of jet size.

  The supply members may consist of a porous or fibrous member, said operating means being able to position the outlet orifice with respect to said selected reservoir, so that said jet of pressurized fluid is directed, at least in part, on said second end of the supply member of said selected reservoir, so that said jet comes, at least partially, into contact with the porous or fibrous member. By way of example, said feed members are formed from a wick, a felt tip, or a frit. Thus, the product can rise by capillary action along these fibrous or porous organs, and thus reach said second end of the supply member. A jet of pressurized fluid on a felt tip, or on the free end of a wick, soaked in a liquid composition, makes it possible to "tear off" particles of said composition from said felt tip or wick, and transport them on the support to be treated. The composition can be

  completely contained in the porous or fibrous element, or only partially.

  In the latter case, the second end of the supply member quenched

  in a "free" composition pool.

  According to an alternative, the supply members consist of a dip tube, said operating means being able to position the outlet orifice relative to said selected reservoir so that said jet of pressurized fluid is directed, at least in part, above the second end of the supply member of said selected reservoir, so as to take a certain amount of the liquid composition which it contains, by Venturi effect. By passing above the tube containing said liquid composition, it creates, due to the speed of the fluid under pressure, above the surface of the liquid, a depression capable of "pumping" the composition contained in the tube. The liquid thus pumped is then entrained by the jet of pressurized fluid, towards the support, on which it is deposited in a relatively localized manner. The geometry of the outlet orifice can be slightly modified compared to the felt or equivalent version, so as to achieve the correct junction between propellant and liquid above the free end of the dip tube. Advantageously, the N tanks are mounted on a tank holder disposed on the container, said maneuvering means allowing a relative rotational movement between the tank holder and said outlet orifice, around the axis of the container. Such a tank holder can have a plurality of housings directly containing the composition in which the feed member soaks. Alternatively, the housings are intended to receive a removable unit, for example, a "felt pen", consisting of a reservoir in which a supply member is arranged. Thus, after exhausting the contents of the tanks, the removable units can be replaced

  easily. The container can itself be refillable with pressurized fluid.

  Preferably, the tank holder is free to rotate relative to the container, and constitutes said operating member, said outlet orifice being stationary in rotation relative to the container. In this configuration, the tank holder can consist of an at least partially annular element mounted in rotation on the upper part of the container, and defining at least N

  housings opening onto a face oriented opposite the bottom of the container.

  The housings are intended to receive the N reservoirs containing the liquid compositions, or to form directly a reservoir for said liquid compositions, said second ends of the feed members emerging relative to said opening face, said outlet orifice opening laterally relative to said container. , in an axial position close to the axial position of said second ends. Preferably, said second ends of the feed members are oriented

  substantially parallel to the axis of the container.

  Means may be provided to allow precise angular positioning of the tank-holder with respect to the container outlet, the position of the second end of the supply member of each of the tanks being fixed relative to the tank-holder. tank. Such angular positioning means may include a mechanism for positioning the tank holder relative to the outlet orifice in at least N positions

  angularly indexed. In these indexed positions, the position of the holder

  tank, and therefore of the second end of the supply member of the selected tank, is stable relative to the outlet, and can be

  obtained precisely without any particular adjustment.

  Advantageously, said positioning mechanism makes it possible to position the tank holder relative to the outlet orifice according to at least N + 1 angularly indexed positions, at least one of the angularly indexed positions corresponding to a storage position in which the outlet orifice is not facing any of the supply members of the N tanks. We thus avoid

  in this storage position, the risk of accidental spraying.

  A hoop can be placed on the container, said hoop being free to rotate relative to the tanks, and comprising protective means for isolating from the outside the second end of the supply member of the tanks other than the selected tank. In the aforementioned storage position, the second ends of all the tanks can be protected from the outside by the hoop. This prevents the product present on the second ends of the feed members from drying out between two uses. For example, the hoop can be snapped onto the

  container. Advantageously, the hoop makes it possible to immobilize the holder axially.

tank on the container.

  Preferably, the actuation command is exerted on an actuating member consisting of a push button mounted on the hoop, said push button comprising a channel in communication with the valve, and one end of which opens onto said outlet orifice. The push button can be connected to the hoop by an articulation zone around an axis substantially perpendicular to the axis of the container, said articulation zone being arranged so that the actuation of the push button does not substantially cause

  no movement of said outlet.

  The hoop and the push button can be formed in one piece obtained by molding a thermoplastic material, said articulation zone being formed by a film hinge. As an example, a polyethylene can be used

or polypropylene.

  The indexed positioning mechanism of the tank holder and the outlet orifice may comprise a ball carried by the hoop (or by the tank holder), and constrained by an elastic return means in the direction of an annular face of the tank holder (or of the hoop), said annular face comprising a plurality of recesses spaced angularly, and capable of receiving a part of the ball when the tank holder occupies any of the hoop

  said positions angularly indexed.

  Said pressurized fluid may consist at least in part of a liquid composition intended to be applied to the support in combination with any one of the liquid compositions contained in said N reservoirs. Thus, the liquid composition contained in the pressurized container can be a: amino acid pressure, intended to be applied in combination with a DHA composition chosen from a plurality of compositions having different concentrations, and contained in the different reservoirs. Alternatively, the liquid composition contained in the pressurized container can be a styling spray, intended to be applied in combination with a coloring composition chosen from a plurality of compositions of different colors, or with a composition containing shine agents. Alternatively still, the liquid composition contained in the pressurized container can be a solution containing vitamins or proteolytic enzymes, intended to be applied in combination with a composition containing salicylic acid, chosen from a plurality of

  compositions having different concentrations.

  The invention also relates to the use of a device according to the invention for the application to a support of a liquid composition chosen from a plurality

  liquid compositions of different colors.

  The invention also relates to the use of a device according to the invention for the application to a support of a first liquid composition in combination with another liquid composition chosen from a plurality of second liquid compositions. Said plurality of second liquid compositions can

  be made up of compositions of different types and / or concentrations.

  The invention consists, apart from the arrangements set out above, of a certain number of other arrangements which will be explained below, with reference to nonlimiting exemplary embodiments, described with reference to the appended figures, among which: - Figures 1A-1D illustrate a first embodiment of the device according to the invention; and - Figures 2A-2C illustrate a second embodiment of the device

according to the present invention.

  In the embodiment illustrated in FIGS. 1A-1D, the device 1 comprises an aerosol container 2 of axis X, containing a pressurized gas, in particular air. The container 2 consists of a container comprising a body 3, one end of which is closed by a bottom 4. On the end 10 opposite the bottom is mounted a valve 5 comprising an emerging rod 6, of the push-in type. The valve is carried by a cup 7 fixed to the container 2 by crimping, forming a bead 9. The valve is itself mounted on the cup 7 by crimping by forming a bead 8, of section smaller than the

bead section 8.

  On the container 2, there is mounted for free rotation a tank-carrying member 11, in annular form, and defining a plurality of housings 12 (in this case 12 as shown in FIG. 1C) inside each of which, apart from a 14, a reservoir 13 is detachably disposed. The housings 12 are of axis Y, parallel to the axis X of the container. Each of the reservoirs 13 is constituted by a cylindrical tube 15, the bottom of which is closed, and the opposite end of which defines an opening 19 through which emerges in leaktight manner, a supply member 16, in the form of a felt. 16 arranged in the Y axis of the reservoir 13 which contains it. The feed members 16 comprise a first end 17 disposed substantially at the bottom of the case, and a second end 18, opposite the end 17, and emerging through said opening 19. The end 18 is cut in shape peak. The end 17 soaks in a reserve of product 20 contained in the tube 15. The product is, for example, a coloring composition used for coloring the hair, of the type comprising a solvent in which color pigments are suspended. Each of the reservoirs 13 comprises a composition of a different color. The reservoirs 13 are arranged slightly

  self-tightening inside the corresponding housings.

  The tank holder comprises an edge 21 folded 90 inwards, and intended to come to bear on the bead 9. The edge 21 forms, on the side opposite the bottom 4 of the container 2, an annular surface 22, in which are formed a plurality of recesses 24 (see Figure 1 D) forming a portion of a sphere, and whose function will be explained in more detail below. The recesses 24 are evenly spaced on the surface 22. In practice, as many recesses 24 are made as there are housings 12. The end 18 of the supply members 16 of each of the tanks emerges slightly at

above the annular surface 22.

  On the container 2 is mounted a hoop 30, which is hooked by snapping on the bead 8. The hoop 30 is fixedly mounted in rotation, in particular by

  tightening, relative to the container, and axially immobilizes the tank holder 11.

  The hoop 30 comprises an annular portion 31, of external diameter substantially equal to the external diameter of the tank holder 11, and covering the felt tips 18 of the tanks 13, so as to isolate them from the outside. To this end, an annular groove 33 is produced in the hoop 30, so as, as will be seen in more detail below, to allow the tank holder 11 to rotate relative to the hoop. The annular portion 31 is interrupted on an angular portion 32 so as to clear the space situated opposite one of the supply members 16. Opposite the interrupted annular portion, opens laterally, via an outlet orifice 40, a channel 34 formed inside a projection 41, connected to a push button 35 by means of a film hinge 36 oriented perpendicular to the axis X of the container 2. The channel 34 forms an angle of approximately 30 with the perpendicular to the axis X of the container 2. The film hinge 36 is arranged at an axial height corresponding to the axial height of the free end of the

  valve stem 6 when the latter is at the halfway point of actuation.

  The outlet 40 is arranged so as to be located as close as possible to the end 18 of the feed member 16 opposite the interrupted portion 32 of the hoop 30. Typically, this distance is order of 1 mm. In the case of a felt tip, or any other fibrous or porous material, the channel 34 is oriented so that the outlet orifice 40 is directly opposite the end 18 of the corresponding felt. For other embodiments of the supply member 16, in particular when it is a dip tube, with supply by Venturi effect, the outlet orifice is oriented so that the jet of pressurized fluid it delivers just flows

  above the free end of the tube 16.

  The projection 41 is directly fixed to the container 2 by means of a hooking tab 37 slammed on the bead 8. The channel 34 extends beyond the film hinge 36, substantially to the right of a chimney axial 38 force-fitted onto the valve stem 6, so as to selectively allow the outlet orifice 40 to communicate with the content of the container 2. The push button 35 consists of a bearing surface 42 oriented substantially perpendicular to the axis X of the container 2. Thus, the film hinge 36 is disposed between the attachment point 37 and the valve stem 6, and preferably as close as possible to the attachment point, so as to do not generate substantially any angular movement of the outlet orifice 40 when the valve is actuated. The distribution head is

covered with a removable cover 55.

  The precise positioning of the tank holder 11 with respect to the outlet orifice is done with an indexing mechanism allowing as many indexed positions as there are housings 12. For this purpose, and as it appears more clearly from Figure 1D, a cylindrical housing 50 is formed in the hoop 30, oriented parallel to the axis X of the container, and opening onto a face 51 located opposite the surface 22 formed by the tank holder. Inside the housing 50, a ball 52 is arranged, constrained in the direction of

  the surface 22, by an elastic return means 53, in the form of a spring.

  As mentioned above, the surface 22 has recesses 24 forming portions of a sphere, arranged regularly over the entire surface 22. Thus, each time that the ball 52 is located opposite a recess 24 formed by the surface 22 , a precise and stable positioning of the tank holder 11 is carried out relative to the hoop 30, and therefore relative to the outlet orifice 40. The number of recesses 24 is identical to the number of housings 12 The setting opposite the housing 14 not containing a reservoir, with the outlet orifice 40 corresponds to the position of non-use or storage of the device In this position, the risks of spraying

  accidental dye are avoided.

  The operation of the device 1 will now be discussed with reference to Figure lB. During an application, the user selects a color to apply. To this end, it rotates the reservoir holder 11 relative to the container 2, and relative to the hoop 30, so as to bring the felt tip 18 corresponding to the selected color opposite the outlet orifice 40 . It exerts pressure on the bearing surface 42 of the push button 35. In doing so, it causes a depression of the valve stem 6 (accompanied by a slight tilting) and the output of a jet of propellant by the orifice 40. The jet of propellant fluid is directed onto the end 18 of the supply member 16 of the selected reservoir 13. By contacting the felt tip loaded with coloring composition, the jet of propellant fluid entrains particles of the composition , and deposits them on the support to be treated. The dispensing is interrupted when the pressure on the surface 42 ceases. To apply another color, at the same location on the surface to be treated, or at a different location, it rotates the reservoir holder 11 relative to the container 2 of

  so as to bring the selected color opposite the outlet orifice 40.

  After application, the user positions the empty housing 14 opposite

  the outlet orifice 40, and closes the assembly by placing the cover 55.

  FIGS. 2A-2C to which reference is now made illustrate a second embodiment of the device 1 according to the invention. This embodiment differs from the previous one in that: the housings 12 formed by the reservoir holder 11 directly contain the composition to be combined with the composition contained in the container 2. The housings are two in number, thus defining two reservoirs 13 extending angularly over approximately 180. The mounting of the tank holder 11 on the container, with respect to the hoop 30 is identical to the mounting of the previous embodiment. Advantageously, the indexed positioning mechanism allows four indexed positions, spaced 90: first two positions spaced 180 in which the outlet orifice 40 is facing one or the other of the supply members 16 of the one or the other of the tanks 13 and two intermediate positions in which the outlet orifice 40 is opposite any of the supply members 16, the two intermediate positions

  being 90 relative to the first two positions.

  - The supply members consist of dip tube, one end 17 of which dips into the bottom of the reservoir 13 and the other end 18 of which emerges from the reservoir 13. The outlet orifice 40 is oriented so that the jet of fluid propellant that it produces passes, at least in part, above the free end of the dip tube 16 (the distance between the jet of propellant fluid and the free end of the dip tube can be of the order of 1 mm or more). In this configuration, the tube is supplied by the Venturi effect. This mode of supply by Venturi effect is very particularly advantageous in that it allows the use of more viscous compositions, in particular of compositions based on polymers, and which one frequently meets in the cosmetic field. It is clear that the representation of the Venturi effect supply system illustrated in FIGS. 2A and 2B is only purely schematic. In practice, the geometry of the outlet orifice can be slightly modified compared to the felt or equivalent version, so as to achieve the correct propellant / liquid junction above the free end of the dip tube. However, such systems are well known.

  in other applications and therefore do not require description

additional detail.

  the channel 34 is oriented substantially perpendicular to the axis X of the

container.

  The operation of this embodiment is illustrated in Figure 2B. In this embodiment, the container 2 contains an amino acid solution, intended to be applied in combination with a DHA composition chosen from two compositions having two different concentrations, and contained respectively in each of the reservoirs 13. The user chooses the composition which it wishes to apply in combination with the composition

  contained in container 2. For this purpose, it rotates the holder

  reservoir 11 relative to the container 2, and relative to the hoop 30, so as to bring opposite the outlet orifice 40, the dip tube 16 corresponding to the selected composition. It exerts pressure on the bearing surface 42 of the push button 35. In doing so, it causes a depression of the valve stem 6 (accompanied by a slight tilting) and the output of a jet of the composition contained in the container 2, through orifice 40. The jet is directed just above the end 18 of the selected dip tube. Passing above the free end of the dip tube, which is filled with composition, the jet creates a depression capable of pumping a certain amount of said composition, and of transporting it on the support to be treated. A mixture of the two compositions is thus applied to the support to be treated. The dispensing is interrupted when the pressure on the surface 42 ceases. To apply another composition, at the same location on the surface to be treated, or at a different location, it rotates the reservoir holder 11 relative to the container so as to bring the dip tube selected opposite the outlet port 40. After application, the user returns the tank holder to one or other of the intermediate positions, relative to the outlet port 40, and closes

The whole by placing the cover 55.

  In the foregoing detailed description, reference has been made to modes of

  preferred embodiments of the invention. It is obvious that variants may exist there.

  be made without departing from the spirit of the invention as claimed above

after.
