Definitions

  • the present invention relates to a device for packaging at least one cosmetic product.
  • the invention is aimed in particular at a device for the extemporaneous mixing of at least two products in order to produce a composition, in particular a cosmetic composition, as used for example in the field of hair dyeing.
  • the device may in particular be of the type comprising a container containing the product, the distribution of the latter being obtainable in response to a pressure exerted on the walls of the container, or by means of a manually operated pump equipping the device.
  • devices of this type it may be desirable, especially with certain products having a high propensity to dry or oxidize in contact with air, to ensure the sealing of the device dispensing orifice. so that any residual product located in the ducts located upstream of the dispensing orifice is kept out of the air.
  • the preparation of a large number of dyeing compositions involves the extemporaneous mixing of two (or even three) products (a dye, an oxidant, optionally a perfume) which, for reasons of of stability must be kept apart from each other until the moment of use of the coloring composition.
  • At least one of the products may be in the form of a powder.
  • each of the products to be mixed is packaged in a packaging of its own, in particular in the form of a tube or a bag.
  • the consumer pours the contents of one of the packages into the other, or the contents of the two packages in a third, within which the mixture is made.
  • EP 0 606 429 discloses a two-chamber mixing system insulated by a first rubber piston which, in response to a pressure exerted by a second piston, is pushed from a first position in which it isolates the two products to a single position. second position in which it delimits, in combination with an inner surface of a throttling zone separating the two chambers, a passage capable of allowing the two products to come into contact with one another.
  • the device is defined by the features of claim 1 divided into two parts with respect to the prior art according to US-A-2002/0 066 750.
  • fluids hydroaulic or liquid or "pneumatic” (air).
  • the passage may be a passage located upstream of an outlet of the device, which passage, outside the product distribution phases, must be kept closed as tightly as possible, to prevent any residual product located upstream of the outlet orifice does not dry or oxidize on contact with air.
  • the passage may be a passage formed between two compartments formed by the device.
  • the device delimits a first compartment containing a first product, and a second compartment, adapted to be disposed at least partly above the first, and containing a second product, a first separation member being adapted to pass from a first position in which it isolates the first product of the second to a second position in which the first product is brought into contact with the second, the device being configured so that the passage of the first separation member from the first to the second position results, at the sensible balance of pressures between the first and second compartments, a volume reduction, especially multidirectional, said first separation member in response to an overpressure generated within one and / or the other of said first and second compartments.
  • the separation member is such that it ensures the physical separation of the two products. On the other hand, it must allow the balance of pressures to be made.
  • at least the product contained in the second compartment and which, when the second compartment is above the first compartment, rests on the separating member, is preferably in the form of a powder.
  • the other product can be in particular in liquid form.
  • a low overpressure is sufficient to cause the passage of the latter from the first to the second position.
  • the volume reduction is reflected at least by a reduction of the surface of the first separation member, transversely to a longitudinal axis of the device, and this over its entire axial height.
  • the separating member in the first position, the separating member is sufficiently large diameter to hold in place by slight tightening, despite the weight of the second product disposed above.
  • the separating member compresses in all directions, in particular radially to its axis. As a result, it is no longer clamping, and, under the effect of its weight, added to the weight of the second product, it falls with it into the first container. The two products are then in contact with each other.
  • the pressure exerted on the separating member being substantially uniform over its entire outer surface, there is also a slight decrease in the axial height of the separating member. In the latter case, the volume reduction is multidirectional.
  • the separating member is made of a material capable of shrinking under the effect of this overpressure, it is therefore able to reduce volume.
  • the overpressure is generated in the first compartment when the latter is below the second, the level of first product in the first compartment being such that the passage from the first to the second position takes place before the first product comes into contact with said first separation member.
  • the pressure exerted on the separating member is pneumatic.
  • the overpressure can be exerted on the compartment disposed above the other.
  • the product contained in the compartment above is a liquid, of density greater than the density of the material forming the separating member, then, in response to the overpressure, the separating member decreases in volume, and is no longer held in the position where it isolates the two compartments. It then rises to the surface of the liquid as it mixes with the product contained in the other compartment.
  • the pressure exerted on the separation member is hydraulic.
  • the first separation member is constituted at least in part by an element formed of an elastically compressible material in response to said overpressure, and at least a portion of the outer surface is impermeable.
  • waterproof is meant to be impermeable to the pressurizing fluid, in particular to air.
  • the material is a closed-cell foam material. It may be in particular a polyethylene foam, polyester or polyurethane.
  • said first separating member floats on the surface of the mixture.
  • the separation member does not disturb the distribution of the mixture.
  • the first separating member is preferably disposed inside a passage formed between the first and second compartments and is, prior to said overpressure, maintained in said first position, by partial compression in at least one direction transverse to said passage, in contact with an inner surface delimiting said passage. Despite this slight compression of the separation member, the air can pass between the lateral surface of the separating member and the inner surface of the passage, thus allowing the achievement of pressure equilibrium.
  • the pressure of the first compartment and the second compartment are substantially identical and each in excess pressure relative to the initial pressure of these compartments.
  • the separating member disposed between these two compartments is in fact compressed in at least two opposite directions, for example the pressure is at least applied to two opposite sides of this member coming into contact with the inner surface of the passage
  • At least one of the walls delimiting one and / or the other of said first and second compartments is elastically deformable so as to be able to generate said overpressure in response to a pressure exerted, laterally or axially, on said resiliently deformable wall.
  • At least a portion of one and / or the other of said first and second compartments may form a bellows.
  • the pressure to exert is axial.
  • the compartment inside which the overpressure is generated is delimited by a container with elastically compressible walls.
  • the pressure to be exerted is transverse to the axis.
  • the first compartment is delimited by a first container, the second compartment being delimited by a second container, adapted to be mounted on the first, in particular by screwing or snapping.
  • the second container then has an opening which, when said first separator member is in the first position, is isolated from the second product by said first separator member.
  • said opening prior to mounting the second container on the first, is closed removably by means of closure, in particular in the form of a plug, in particular screwed.
  • Means are provided for, prior to mounting the second container on the first, maintain in a fixed position said first member separation.
  • the cap As long as the cap is in place on the second container, it axially immobilizes the separating member. Once the cap is removed, when positioning the second container above the first, the second product is retained within the second container by the separating member.
  • the second compartment is delimited by an element forming an applicator tip for mixing said products.
  • the second compartment is able to communicate with a dispensing orifice which, prior to mixing, is closed by a closure member, in particular in the form of a self-breaking element.
  • the device forms a third compartment adapted to be disposed at least partly above the second and containing a third product, said first, second and third products being isolated in pairs by said first separation member. and by a second separating member, said first and second separating members being adapted to pass each of a first position in which they isolate two by two said first, second and third products, at a second position in which the three products are brought into contact with each other, the passage of the first and second separating member from the first position to the second resulting, the sensible balance of pressures between the compartments they respectively separate, a volume reduction multidirectional of said first and second separation member in response to an overpressure generated within one and or the other of said first, second and third compartments.
  • the mixture is made by positioning the device so that the second compartment is above the first, the third, above the second, and pressurizing the first.
  • the second and third products may be packaged separately from each other, in the same container, in particular in an applicator tip.
  • the (or) product (s) contained in the (or) compartment (s) other (s) than that inside which is generated said overpressure is (are) in powder form.
  • the first product may be an oxidant in liquid form.
  • the second product may be a dye in the form of a powder.
  • the third product may be a perfume composition, in the form of a powder as well.
