Definitions

  • the invention relates to a casing for a powder cosmetic product comprising an improved opening-closing device.
  • the invention relates more particularly to a casing for a powder cosmetic product, comprising at least a cover and a base which are mounted movably relative to each other between at least a closed position and an open position of the casing, in which the base comprises a cavity intended to receive said pulverulent cosmetic product which is closed by an opening-closing device, said opening-closing device comprising at least first means which, comprising first orifices in communication with the cavity, are integral of the base, and of the second means which, comprising second orifices, are mounted to be movable in rotation with respect to the first means between at least one closed position and one position of use.
  • the housing comprises a base comprising a cavity intended to contain a powder cosmetic product, a sieve which is arranged at the level of the opening of the cavity and through the orifices of which the cosmetic product is discharged with a view to its. use.
  • the screen is rigid.
  • the screen is for example produced in the form of a perforated plate provided with orifices, such as a network of circular holes.
  • Such a housing has the particular drawback of exhibiting a dispersion of the pulverulent cosmetic product through the multiple orifices of the sieve, in other words an uncontrolled unloading of said product from the cavity forming the reservoir.
  • Dispersion of the cosmetic product through the sieve is liable to occur, on the one hand, during transport of the housing (in the closed position) and, on the other hand, during use of the housing (in the open position).
  • the dispersion of the cosmetic product is limited by a cover which in the closed position covers the sieve.
  • the dispersion of the powder cosmetic product is further inevitable since it is necessary to shake or invert the casing in order to obtain delivery of the cosmetic product.
  • Such gestures are even more important when, during use, the amount of cosmetic product present in the cavity decreases.
  • the sieve used is “flexible” in order in particular to allow access to the cosmetic product located in the cavity and, by comparison with a rigid sieve housing, without necessarily having to. shake the housing.
  • the flexible sieve is for example produced in the form of a grid, made of nylon or other material, consisting of a set of meshes each delimiting one of the orifices for passage of the pulverulent cosmetic product out of the cavity.
  • such a housing has the particular drawback of having a dispersion of the pulverulent cosmetic product through the multiple orifices of the sieve, on the one hand during transport of the housing (in the closed position) and, on the other hand, during use of the housing (in the open position).
  • an applicator - typically a sponge - so that at least part of the cosmetic product dispersed through the orifices is captured by the sponge.
  • the sponge does not completely prevent the dispersion of the pulverulent cosmetic product out of the cavity, which poses a problem of hygiene (or cleanliness) of the housing.
  • the sponge then comprises on its face in contact with the grid an often excessive quantity of cosmetic product so that the saturated sponge is then difficult to use for applying make-up.
  • a stopper for example integral with the cover of the housing.
  • Such a stopper is configured to cover the sieve in the closed position of the housing so as to isolate it and thus prevent the pulverulent cosmetic product from being able to disperse.
  • the cosmetic product present on the surface of the stopper is then liable to disperse everywhere after opening the cover, in particular from dirtying the housing, the user's hands, etc.
  • Such a design also has the drawback of adding, with said stopper, an additional part to the cover, or even an additional part to the casing, which in particular has the consequence of increasing the manufacturing cost thereof.
  • the cap does not completely solve the problem of dispersion because the problem of dispersion or uncontrolled unloading is not limited to the only case of transporting the housing but also occurs during use, when the housing is in the open position. .
  • the sieve is generally sized to have a reduced surface area, in particular a surface smaller than the diameter of the housing, which furthermore has the consequence of limiting the gestures of the user handling an applicator during the application. use of the housing.
  • the reduction of the surface of the flexible sieve makes it possible to reduce the phenomenon of dispersion of the cosmetic product, the volatility of which would otherwise be too great.
  • the pulverulent cosmetic product will disperse, spread, when the applicator comes into contact with the sieve, or even when the base of the housing is shaken to discharge the product onto an applicator such as a sponge.
  • the housing comprises an opening-closing device of the rotary type comprising a first screen and a second screen which are superimposed and one of which is mounted to be movable in rotation with respect to the other, respectively between a shutter position and a position of use.
  • the closed position of the opening-closing device corresponds to a position in which the orifices of the second sieve are angularly offset with respect to the orifices of the first sieve arranged below so as to block the passage of the pulverulent cosmetic product contained in a cavity of the base of the housing which the said opening-closing device closes.
  • the position of use of the opening-closing device corresponds to a position in which the orifices of the second sieve are superimposed with the orifices of the first sieve so as to allow the passage of the pulverulent cosmetic product successively through the orifices of the first sieve and the orifices of the second screen.
  • the orifices passing through the screens are for example formed by a network of holes or perforations.
  • An opening-closing device of this type makes it possible to eliminate the use of a stopper described above for a housing comprising a single sieve.
  • the opening-closing device of such a housing having been previously actuated to occupy said position of use, the distribution of the cosmetic product through said orifices of the two superimposed sieves is obtained by overturning the housing, or even by stirring. or by shaking the base of the case.
  • the gestures associated with the delivery of the cosmetic product from such a case during its use greatly generate a dispersion of the cosmetic product.
  • the powdered cosmetic product delivered disperses without control when it leaves the orifices of the sieves, for example to be collected by means of an applicator or sometimes in the cover.
  • the quantity delivered by the opening-closing device is predetermined by the configuration of two screens, more particularly the number of orifices, the dimensions of the orifices, etc. so that the amount of powder cosmetic product is delivered without control or great precision.
  • the dispersion of the cosmetic product occurring during use directly affects the general hygiene of the housing, including subsequently during transport and despite the opening-closing device.
  • the powdered cosmetic product thus dispersed is capable of escaping outside the housing even when the latter is closed by a cover.
  • An aim of the present invention is to provide a new design of an opening-closing device for a casing for a powder cosmetic product in order in particular to resolve at least part of the drawbacks of the state of the product.

  • the flexible membranes are made of an elastomeric material, preferably of silicone.
  • the flexible membranes according to the invention are generally more rigid.

  • the orifices of the flexible membranes participate in increasing the elasticity of the membranes, in increasing their capacity for elastic deformation in use, in particular under the action of an applicator.
  • said orifices formed by non-rectilinear radial slots, in particular curved or curved make it possible, by perforating each of the membranes, to obtain an additional deformation capacity, without however having to reduce the thickness of the flexible membranes at the risk of weakening them.
  • slits having a curved or curved shape make it possible to obtain an increased deformation of the membrane at the level of the bearing zone of the applicator.
  • the axis of deformation or of folding of a flexible membrane comprising slots having such non-rectilinear shapes is an axis which extends radially from one end to the other of the slot and is located outside the slit, in the membrane material between consecutive slits.
  • the deformation obtained would be less with a membrane comprising rectilinear slots for which said deformation axis extending radially from one end to the other of the slot coincides with one of the edges of the slot and this which then limits the possibility of access to the bottom of the cavity or its periphery.
  • the pressure exerted locally by an applicator on the flexible membranes causes a deformation of the non-rectilinear slits located in the contact zone and is advantageously accompanied by a phenomenon of “closing” of the slits located radially opposite the contact zone.
  • the slits will stretch radially due to the deformation of each of the flexible membranes and thereby shrink, their radial edges approaching, which then makes it possible to limit the dispersion of the powder cosmetic product in the areas which are not. not in contact with the applicator.
  • the opening-closing device of the case according to the invention makes it possible at the very least to limit, thanks to the membranes, the dispersion of the pulverulent cosmetic product, and this both during transport and during use of the case.
