Description

The present invention relates to a device for packaging a cosmetic product. The invention relates more particularly to a device comprising a container containing the product to be applied and t sieve through which can take place the product contained in the container. Many devices of this type are known, with sieves having dispensing orifices through which the outlet of the product is obtained, of various shapes and arrangements. The sieve may or may not be follower, that is to say, sink or not in the container as and when dispensing the product and emptying the container. The application CN20266461 3 discloses a device comprising a sieve having a central distribution orifice of hexagonal section and a plurality of dispensing orifices arranged around this central orifice, each of oblong shape and large axis oriented substantially radially.

The publication JP2003-79425 discloses a device whose sieve is constituted by a grid fixed on a support frame provided with tabs which can flex against the edge of the housing of the container containing the product, when the sieve is sinking into the container as and as you dump it. Document FR2815832 teaches a device comprising a closing element and an applicator which, in the closed position of the closure element, bears against a compressible porous member allowing the applicator to be loaded in product. FR2856255 discloses a makeup powder container having a separating member of elastic material, cutouts being formed through this separating member. The blanks are closed when no mechanical stress is applied and open by stretching the separating member during use to allow the makeup powder to pass through the separating member. There is a need for further refinement of the sieving devices, in particular to simplify manufacture and improve application of the product and / or loading of an applicator. The invention achieves this objective by means of a device for packaging a cosmetic product, comprising: - a container containing the product to be applied, - a sieve, comprising a cellular and deformable material, through which the product outlet is made contained in the container, the container having a bottom, the sieve being able to come into contact with the bottom of the container when the product is exhausted in the container.

The alveolar character of the material constituting the sieve may, in the case of open porosity, allow the product contained in the container to pass easily through the sieve from its lower surface to its upper surface, so that the user can take the sieve. produced on the upper surface of the sieve. An adequate dose of product can be taken from the upper surface of the sieve. In particular, the device makes it possible to limit and control the quantity of product withdrawn, by imposing the interface constituted by the sieve between the user and the mass of product contained in the container. The sieve can retain some of the product in the pores. The honeycomb character may also allow the sieve to exhibit a relatively rough surface condition and favorable to shear the product at the time of sampling, which may allow a more homogeneous loading of the applicator. The product may for example be taken with the finger, a sponge, a plastic applicator, flocked or not, or a brush. The ability of the sieve to contact the bottom of the container when the product is exhausted in the container allows almost complete emptying of the container product. The sieve may be adapted to conform to the shape of the bottom of the container when the product is exhausted in the container. The screen has a bottom surface facing the product contained in the container and an upper surface opposite the product contained in the container.

The maximum thickness between the lower surface and the upper surface of the screen is also called the thickness of the screen, the latter may still be called membrane. The thickness of the sieve can be between 0.4 and 5 mm. The area of the upper surface of the sieve may be between 180 mm 2 and 3800 mm 2. Such an area of the upper surface and such a thickness of the sieve allow to have a large area of access to the product by the user while minimizing the amount of cellular material needed and the amount of product remaining trapped sieve at the end of 'use. The screen is preferably entirely constituted by the cellular material. Depending on the initial degree of filling of the container, and the follower or non-sieve character, the product contained in the container may or may not be in contact with the lower surface of the sieve in the absence of user biasing it. . Preferably, the sieve marries the surface of the product contained in the container during sampling. The screen is preferably elastically deformable. This allows the sieve to deform under the pressure exerted by the user so that its bottom surface comes into contact with the product contained in the container, if the product is not already in contact with the bottom surface of the sieve. absence of solicitation. When the product is already in contact with the bottom surface of the sieve, at rest, this facilitates the loading of the sieve into product and increases the amount of product available at the top surface of the sieve for the user. The screen may comprise, in particular, a PU polyurethane foam, a PE polyethylene foam, an EVA foam, a PVC foam, an impregnated PU foam, an EPDM cellular rubber, a neoprene cellular rubber, a nitrile cellular rubber (NB * - VC), neoprene compact rubber, EPDM hard rubber, SBR solid rubber, nitrile compact rubber, sponge rubber (EPDM, neoprene, silicone), polyether and / or polyester. The alveolar material may be open-celled. In a variant, the cellular material is closed cell, the screen being then traversed by one or more through holes, which are for example made by laser cutting. When the sieve material is open cell, the sieve may be devoid of through hole made by cutting or drilling. The screen is preferably monolayer or multilayer. For example, there are several layers of material having distinct porosities. Whether open cell or not, the screen may have through holes. The through orifices may each have a circular section or not, including polygonal.

The through orifices may be of constant section or [according to their thickness. The through orifices may be made by drilling and / or cutting, in particular by laser.

The screen may have non-through cavities, especially when it is open-cell, made for example by cutting, drilling or grinding. These cavities by locally reducing the thickness of the material, can help the sieve pass through the product. The sieve may be follower or not.

The product is preferably fluid. The viscosity of the product may be between 40 and 90 UD (Deviation Unit), preferably between 55 and 80 UD, or between 366 and 569 cP (centipoise), or between 0.37 and 0.57 Pa.s. This viscosity is measured at 25 ° C., with a Rheomat 180 (Lamy) equipped with an MS-R2 axis, selected according to a low to medium viscosity of the product, which rotates at a speed of 200 rpm. The measurement is taken after a rotation of 10 minutes. The viscosity measurements are carried out at the latest one week after manufacture. Such viscosity improves the setting of the product on the upper surface of the sieve and prevent the product from sinking during use.

Taking the product on the upper surface of the sieve can be done using an applicator. This applicator may comprise or consist of an applicator member such as a foam, a brush, a sponge, a nonwoven, a flocked tip. Alternatively, the product is taken by finger, passing it on the sieve.

The product is preferably a cosmetic product. It can be a foundation or a concealer, an concealer, or a care product. The upper surface of the sieve may be substantially flat, in its portion traversed by the product during use. The lower surface of the sieve may be substantially flat, on its part traversed by the product during use.

The thickness of the sieve may be substantially constant, in its portion traversed by the product during use.

The thickness of the sieve may be substantially constant prior to its integration into the device, the sieve being for example made by cutting a disc of a film of cellular material. The areas of the upper and lower surfaces of the sieve may be equal or different. The device may comprise a protective cover, which covers the screen in the absence of removal of the product. The protective cover can be fixed on the body of the container by friction, screwing, bayonet locking or latching.

Alternatively, the protective cover can be hingedly connected to the body of the container or by a slide connection. The device may be devoid of applicator housed between the protective cover and the screen. This simplifies manufacturing compared to devices in which an applicator is integrated, and allow greater freedom of choice to the user for the application of the product. The device may, in a variant, include an applicator, so as to provide a complete system to the user. The device may comprise a mirror, in particular housed in the protective cover.

The screen may be attached at its periphery to the rest of the device. The screen may be fixed at its periphery to the rest of the device by at least one lower ring and at least one upper ring for holding the screen. The latter can be pinched between the upper and lower rings, which allows an effective maintenance of the sieve.

The upper and lower rings can cooperate with each other by snapping or otherwise. The upper ring, respectively lower, may comprise for this purpose a hooking relief and the lower ring, respectively upper, may comprise an annular groove in which the hooking relief can snap.

At least one of the upper and lower rings, better both the lower ring and the upper ring, may have one or more hooking pins inserted in the sieve, so as to further improve the maintenance of the sieve by hanging.

The container may comprise an annular groove for receiving the lower ring. Alternatively, the screen may be attached at its periphery to the rest of the device by at least one ring overmolded with the screen.

In another variant, the screen may be fixed at its periphery to the rest of the device by clamping between the container and at least one fixing ring. The container may comprise a relief, such as another annular groove, in which is snapped into one of the upper or lower rings, in particular the upper ring.

The bottom container may be concave to the sieve. The bottom of the container may be of paraboloidal, ellipsoidal or spherical shape. Preferably, the sieve may reversibly come into contact at any point in the bottom of the container, in the absence of product, and when a corresponding pressure is exerted. to press against the bottom of the container. The container may comprise a rigid body. The rigid body may be made by molding a thermoplastic material, with a cavity defining the space receiving the product. The container may be a container other than a flexible sheet.

The invention also relates to a makeup process, comprising the steps of: - loading into product an applicator using a device according to the invention, - apply roduit on an area to make up human keratin materials.

The applicator is loaded without movement of the applicator other than a bringing together and then removal of the sieve, which causes the product to be deposited on the applicator. Alternatively, at the time of sampling, the user can rotate and / or translate the applicator in contact with the screen.

The gripping of the product can be done by friction or tapping of the applicator or finger on the sieve.

The invention will be better understood on reading the following detailed description, non-limiting examples of implementation thereof, and on examining the appended drawing, in which: FIG. In axial section, an exemplary device according to the invention, - Figure 2 is an exploded view of the device of Figure 1, Figure 3 represents in isolation, in axial section, the container of the device of Figures I and 2, - FIG. 4 represents, in axial section, the lower ring of the device of FIGS. 1 and 2; FIG. 5 represents, in axial section, the upper ring of the device of FIGS. 1 and 2; FIG. FIG. 7 is a view similar to FIG. 1 of an alternative embodiment of the invention. The packaging device 1 shown in FIGS. 1 and 2 comprises -; X-axis container 10 containing a cosmetic product P to be applied, a screen 30 and a protective cover 40. The protective cover 40 has an internally threaded mounting skirt 23 arranged to be screwed onto a threaded neck 13 present in upper part of the body 11 of the container 10. The protective cover 40 can accommodate a seal 24 which bears, when the cap is screwed on the threaded neck 13, against the upper end edge thereof.

The seal 24 is for example in the form of a disc. The screen 30 is in the example in the form of a film of a cellular material of thickness e substantially constant over its portion through which the product during use. This thickness e of the screen 30 is for example between 0.4 and 5 mm.

The area of the upper surface Ssup of the screen 30 is for example between 180 mm2 and 3800 mm2.

The area of the upper surface S1 of the screen 30 is for example between 180 MM2 and 3800 mm2. The screen 30 is elastically deformable, for example being made of polyurethane foam.

The product P is preferably fluid at ambient temperature (20 ° C.), being, for example, a foundation or a concealer, a concealer, a composition for the lips, or an eyeshadow. The device 1 for packaging and application comprises a lower ring 60 and an upper ring 70 for holding the screen 30, which is clamped between the two rings. The body 11 of the container 10, shown in isolation in Figure 3, has an annular groove 19 for receiving the lower ring 60. The bottom of the annular groove 19 is of rectangular shape. The annular groove 19 is delimited radially inwardly by a rib 18 on which the screen 30 bears. The screen 30 is folded at its periphery 31 downwards between the two rings 60 and 70. The lower ring 60 and the upper ring 70 cooperate by snapping. Figures 4 and 5 respectively represent the lower rings 60 and upper 70 separately. The upper ring 70 has hooking reliefs 71 and the lower ring 60 has a corresponding annular groove 61 in which snap-fastening reliefs 71 snap. The upper and lower rings 60 and 70 each have snap pins 81 which penetrate in the sieve 30. These attachment pegs 81 are for example of pyramidal or conical shape, and their height is for example between 0.5 and 4 mm. The hooking pins 81 of the upper ring 70 and the lower ring 60 can be located vis-a-vis. The screen 30 is thus both pinched between the two rings 60 and 70 and hooked to the two rings via the hooking pins 81.

The lower ring 60 may comprise, as illustrated, a first upright 62a, radially innermost, intermediate upright 62b and a third upright 62e, radially outermost. The uprights 62a and 62b are connected by a first annular wall 63a, and the uprights 62b and 62e are connected by a second annular wall 63b. The walls 63a and 63b are oriented perpendicular to Faxe X, while the uprights 62a, 62b and 62e are tubular and coaxial with the axis X. The groove 61 is formed on the radially inner face of the upright 62e. The pins 81 are carried by the wall 63a. The latter extends back from the upper edge of the uprights 62a and 62b, so that the pins 81 extend in an annular groove formed between the uprights 62a and 62b, above the wall 63a. The pins 81 do not protrude out of this groove. The 62th amount is higher than the others. The upper ring 70 comprises a first tubular upright 72a which is connected superiorly to a transverse wall 73. This first upright 72a bears the hooking reliefs 71. The upper ring 70 comprises a second upright 72b, radially inner to the first, whose end lower door pins 81, and a third amount 72e radially inner second 72b. When the rings 60 and 70 are assembled, the third upright 72e is positioned opposite the first 62a, the screen 30 being clamped between the two. The second amount 72b engages in the groove formed between the uprights 62a and 62b, above the wall 63a. The first amount 72a engages between the amounts 62b and 62e, and comes to press the sieve 30 at the periphery 31 against the amount 62b. The wall 73 bears against the upper edge of the upright 62e.

The radially inner surface of the neck 13 has an annular groove 14 in which the radially outer edge 91 of the upper ring 70 snaps into engagement. The container 10 has a bottom 12, of spherical shape, concave towards the screen 30, for example radius of curvature between 30 and 60 mm, for example 45 mm. To use the device 1, the user removes the protective cover 40.

The user can then apply an applicator 20 against the upper surface Ssup of the sieve 30, as shown in FIG. 6. The user can simply apply the applicator to the upper surface Ssup of the sieve 30 without any movement of the applicator 20. that approximation and then removal of the sieve 30, preferably applying pressure thereon during contact between the applicator 20 and the sieve 30, which causes the product P to be deposited on the applicator 20. Alternatively, at the time of sampling, the user can rotate and / or translate the applicator 20 or the upper surface of the screen 30. The user can load the applicator 20 at will by pressing the screen 30. L In particular, the user can press the sieve 30 several times in a cycle of compression / expansion of the cellular material, in order to increase the loading of the sieve 30 into product P. Once the applicator is loaded with product P, the user can veni d dab the skin with the applicator 20 in order to apply the product P present on the applicator 20. The user can blur as much as necessary the product P thus deposited with the same applicator 20, by moving it on the skin , or using another applicator. FIG. 7 shows a variant of the device according to the invention, comprising a lower ring 60 having holes in which pins 100 of the upper ring engage, the screen 30 being clamped between the two rings and perforated by the pins 100 The screen 30 is shown schematically in FIG. 7 between the bottom 60 and upper 70 rings: the squeezing of the screen 30 between these and the corresponding deformation has not been reproduced. The seal 24 in the example of Figure 7 is annular. The protective cover 40 can accommodate a mirror 80. The screen 30 may have through-holes 35, as illustrated. Of course, the invention is not limited to the examples illustrated and it is possible in particular to combine with one another characteristics of the illustrated examples within variants that are not illustrated. For example, the screen of Figure 1 may be provided with through holes. That of Figure 6 may be lacking.

Other variants are possible. For example, the screen 30 may be movable in the container 10 along the X axis to accompany the lowering of the level of the product P as the samples taken. In this case, it is for example fixed at its periphery to a rigid frame sliding in the housing containing the product.

The expression "comprising one" must be understood as being synonymous with "comprising at least one" .10
