Description

DESCRIPTION

Device comprising a screen comprising a cellular material

[0001] The present invention relates to a device for packaging a cosmetic product.

[0002] The invention relates more particularly to a device comprising a container with a product to be applied and a screen through which the product contained in the container can exit.

[0003] Numerous devices of this type are known with filters having dispensing holes through which the product exits, which have various shapes and arrangements. The filter may or may not be a follower, ie it may or may not descend into the container during product dispensing and container emptying.

[0004] Application CN202664613 discloses a device comprising a sieve having a central dispensing orifice with a hexagonal cross-section and a plurality of dispensing orifices arranged around this central orifice, where each one has an elongated shape and a main axis that extends substantially radially oriented.

[0005] Publication JP2003-79425 discloses a device where the screen is constituted by a grid fixed to a support frame provided with tabs that can be folded against the edge of the housing of the container containing the product when the screen descends into the container during its emptying.

[0006] Document FR2815832 teaches a device comprising a closure element and an applicator which, in the closed position of the closure element, rests against a compressible porous member allowing the applicator to be loaded with the product.

[0007] FR2856255 discloses a make-up powder container comprising a separating element made of elastic material, with cuts formed through this separating element. The slits close when no mechanical pressure is applied and are stretched open by the partition element during use to allow makeup powder to pass through the partition element.

[0008] KR 200 473 939 Y1 discloses a container provided with a rubber discharge pad.

[0009] Application WO 03/029098 A1 describes a device comprising an element that is fixed to a support, where the element is connected to the support by means of the material of a protruding part of the support.

[0010] Patent application EP 1277418 A1 teaches a device comprising a housing that retains a substance and a screen. The device comprises two elements sliding relative to each other to provide a reduction in a volume of the housing when the substance is dispensed from the housing.

[0011] KR 200473573 Y1 and US 2158099 describe containers equipped with a screen. No cellular material is disclosed. JP2008099895A also discloses a container with a screen.

[0012] There is a need to further improve packaging devices comprising a screen, in particular to simplify their production and to improve product application and/or loading of an applicator.

[0013] The invention achieves this objective by virtue of a device for packaging a cosmetic product, comprising:

• a container with the product to be applied,

• a sieve, comprising a cellular and deformable material, through which the product contained in the container comes out,

where the container comprises a bottom, where the screen can contact the bottom of the container when the product in the container is finished, where the container has a concave shape relative to the screen and the screen is capable of molding itself to the shape of the bottom of the container when the product (P) in the container is finished.

[0014] The cellular nature of the material that constitutes the screen can, in particular in the case of open porosity, allow the product contained in the container to pass easily through the filter from its lower surface to its upper surface so that the user can pick up the product from the upper surface of the filter.

[0015] A suitable amount of product can be collected from the top surface of the screen. In particular, the device makes it possible to limit and control the amount of product collected, by providing the interface constituted by the screen between the user and the mass of product contained in the container.

[0016] The screen can retain part of the product in the pores.

[0017] The cellular nature can also allow the filter to have a relatively rough surface that favors the shearing of the product when it is collected, thus allowing a more homogeneous loading of the applicator.

[0018] The product can be picked up, for example, with a finger, a sponge, a flocked or non-flocked plastic applicator, or a fine brush.

[0019] The ability of the screen to contact the bottom of the container when the product in the container has been depleted allows the container to be almost completely emptied of product.

[0020] The screen can conform to the shape of the bottom of the container when the product in the container has been depleted.

[0021] The screen comprises a lower surface oriented towards the product contained in the container and an upper surface facing away from the product contained in the container.

[0022] The maximum thickness between the lower surface and the upper surface of the screen is also called the thickness of the screen, it being possible that the latter is also called the membrane.

[0023] The thickness of the screen can be between 0.4 and 5 mm.

[0024] The area of the upper surface of the screen can be between 180 mm2 and 3800 mm2.

[0025] Such a top surface area and screen thickness allow a large surface area for the user to access the product, while minimizing the amount of cellular material that is needed and the amount of product that gets trapped in the product. sieve at end of use.

[0026] The screen preferably consists entirely of cellular material.

[0027] Depending on the degree of initial filling of the container, and whether or not the screen is a follower, the product contained in the container may or may not be in contact with the lower surface of the screen when pressure is not exerted on it by the user. Username.

[0028] Preferably, the screen hugs the surface of the product contained in the container while said product is collected.

[0029] The screen is preferably elastically deformable. This allows the screen to deform under the pressure exerted by the user so that its lower surface comes into contact with the product contained in the container, if the product is no longer in contact with the lower surface of the filter when pressure is not being exerted. . When the product is already in contact with the bottom surface of the screen, at rest, it is easier to load the screen with product and increase the amount of product available to the user on the top surface of the screen.

[0030] The filter may comprise, in particular, a PU polyurethane foam, a PE polyethylene foam, an EVA foam, a PVC foam, an impregnated Pu foam, a cellular EPDM rubber, a cellular neoprene rubber, a cellular nitrile rubber (NBR/PVC), a compact neoprene rubber, a hard EPDM rubber, a solid SBR rubber, a compact nitrile rubber, a sponge rubber (EPDM, neoprene, silicone), a polyether and/or a polyester.

[0031] The cellular material may be an open cell material.

[0032] In a variant, the cellular material is a closed-cell material, where the screen has one or more through holes passing through it, where said through holes are made, for example, by laser cutting.

[0033] When the screen material is an open cell material, the screen may not have through holes produced by cutting or drilling.

[0034] The screen is preferably single layered or multilayered. There are for example a plurality of material layers with different porosities.

[0035] Whether or not it has open cells, the screen may have through holes. The through holes may each have a circular or non-circular, in particular polygonal, cross-section.

[0036] The through holes may have a constant or non-constant cross-section through their thickness.

[0037] The through holes can be produced by drilling and/or cutting, in particular laser cutting.

[0038] The filter may have cavities that are not through cavities, in particular when it is made of an open cell material, where said cavities are produced for example by cutting, drilling or friction. By locally reducing a thickness of the material, these cavities can help the product pass through the filter.

[0039] The filter may or may not be a follower.

[0040] The product is preferably fluid.

[0041] The viscosity of the product can be between 40 and 90 UD (unit of deviation), preferably between 55 and 80 u D, or between 366 and 569 cP (centipoises), or between 0.37 and 0.57 Pa.s.

[0042] This viscosity is measured at 25°C with a Rheomat 180 (Lamy) equipped with an MS-R2 spindle, selected for low to medium product viscosity, rotating at a speed of 200 revolutions per minute. The measurement is taken after a rotation time of 10 minutes. Viscosity measurements are made no later than one week after production.

[0043] Such viscosity makes it possible to improve the collection of the product from the upper surface of the screen and to prevent the product from flowing during use.

[0044] The product can be collected from the upper surface of the screen with the aid of an applicator. This applicator may comprise or consist of an applicator element such as a foam, a brush, a sponge, a nonwoven, or a flocked end piece.

[0045] In a variant, the product is collected with a finger, the latter passing over the filter.

[0046] The product is preferably a cosmetic product. The latter can be a foundation or complexion corrector, a concealer product, or a care product.

[0047] The upper surface of the filter may be substantially flat at the part through which the product passes during use. The bottom surface of the filter may be substantially flat at the part through which the product passes during use.

[0048] The thickness of the filter may be substantially constant at its portion through which the product passes during use.

[0049] The thickness of the filter may be substantially constant before it is integrated into the device, where the filter is made for example by cutting out a disk from a film of cellular material.

[0050] The areas of the upper and lower surfaces of the filter may be the same or different.

[0051] The device may comprise a protective cap that covers the filter when the product is not being collected.

[0052] The protective cap can be attached to the container body by friction, screwing, bayonet locking or snap-fitting.

[0053] In a variant, the protective cap can be connected to the container body in a hinged manner or by a sliding connection.

[0054] The device may not have an applicator placed between the protective cap and the filter. This makes it possible to simplify manufacturing compared to devices where an applicator is incorporated, and to give the user more freedom of choice in applying the product.

[0055] In a variant, the device may comprise an applicator to provide the user with a complete system.

[0056] The device may comprise a mirror, placed in particular on the protective cover.

[0057] The device may not comprise any squeegee element through which the applicator is extracted.

[0058] The device may not comprise any bellows, in particular in the container.

[0059] The filter can be fixed at its periphery to the support of the device, in particular at a distance from the bottom of the container that does not vary with the amount of product present in the container.

[0060] The filter can be fixed at its periphery to the support of the device by at least one lower ring and at least one upper ring to retain the filter. The latter can be gripped between the upper and lower rings, thus making it possible for the filter to be held effectively.

[0061] The upper and lower rings may be attached to each other by snap fit or in some other way.

[0062] To this end, the upper ring or the lower ring may include a mating relief and the lower ring or the upper ring may include an annular groove in which the mating relief can be pressed.

[0063] At least one of the upper and lower rings, or better yet, both the lower and upper rings, may comprise one or more capture spikes inserted into the filter, to further enhance filter hold by capture.

[0064] The container may comprise an annular groove for receiving the lower ring.

[0065] In a variant, the filter can be attached at its periphery to the rest of the device by means of at least one ring overmolded with the filter.

[0066] In another variant, the filter can be fixed at its periphery to the rest of the device by holding it between the container and at least one fixing ring.

[0067] The container may comprise a relief, such as an annular groove, in which one of the upper or lower rings, in particular the upper ring, is press fit.

[0068] The bottom of the container has a concave shape towards the filter.

[0069] The bottom of the container may have a parabolic, ellipsoidal or spherical shape.

[0070] The bottom of the container can be located approximately at the same level as the bottom of the packaging and application device.

[0071] The filter reversibly contacts the bottom of the container, when there is no product, and when a corresponding pressure is exerted from above to press it against the bottom of the container.

[0072] The filter reversibly contacts any point on the bottom of the container, when there is no product, and when a corresponding pressure is exerted from above to press it against the bottom of the container.

[0073] The container may comprise a rigid body.

[0074] The rigid body can be produced by molding a thermoplastic material, with a cavity defining the space containing the product.

[0075] The container may be a container other than a flexible sheet.

[0076] Another object of the invention is a makeup method comprising the steps of:

- loading an applicator with product using a device according to the invention,

- apply the product to an area to be made up of human keratin materials.

[0077] The applicator can be loaded without moving the applicator other than moving it into contact with the filter and then away from it, causing product to deposit on the applicator.

[0078] In a variant, at the time the product is collected, the user can rotate the applicator and/or move it in translation in contact with the filter.

[0079] The product can be caught by friction or by hitting the applicator or the finger on the filter.

[0080] The invention can be better understood by reading the following detailed description of non-limiting implementation examples thereof and by examining the attached drawing, where:

- Figure 1 shows, in axial section, an example of a device according to the invention,

- Figure 2 is an exploded view of the device of Figure 1,

- Figure 3 shows, in axial section, the container of the device of figures 1 and 2 alone,

- Figure 4 shows, in axial section, the lower ring of the device of figures 1 and 2 on its own,

- Figure 5 shows, in axial section, the upper ring of the device of figures 1 and 2 alone,

- Figure 6 illustrates an example of product collection, and

- Figure 7 is a view similar to that of figure 1 of a variant of the invention

[0081] The packaging device 1 represented in figures 1 and 2 comprises a container 10 with axis X containing a cosmetic product P to be applied, a filter 30 and a protective cap 40.

[0082] The protective cap 40 comprises an internally threaded mounting skirt 23 that is designed to be screwed onto a threaded neck 13 that is present in the upper part of the body 11 of the container 10.

[0083] The protective cap 40 can house a gasket 24 which, when the cap is screwed onto the threaded neck 13, presses against the upper end edge of the latter.

[0084] The seal 24 is, for example, in the form of a disk.

[0085] In the example in question, the filter 30 is in the form of a film of cellular material of substantially constant thickness e in its part through which the product passes during use.

[0086] This thickness e of the filter 30 is, for example, between 0.4 and 5 mm.

[0087] The upper surface area Ssup of the filter 30 is, for example, between 180 mm2 and 3800 mm2.

[0088] The bottom surface area Sn of the filter 30 is, for example, between 180 mm ² and 3800 mm ² .

[0089] The filter 30 is elastically deformable and is made, for example, of polyurethane foam.

[0090] The product P is preferably fluid at room temperature (20°C), being for example a foundation or complexion corrector, a concealer, a lip composition or an eye shadow.

[0091] The packaging and application device 1 comprises a lower ring 60 and an upper ring 70 to support the filter 30, which is held between the two rings.

[0092] The body 11 of the container 10, shown only in Figure 3, comprises an annular groove 19 for receiving the lower ring 60. The bottom of the annular groove 19 has a rectangular shape.

[0093] The annular groove 19 is delimited radially inwards by a rib 18 against which the filter 30 rests.

[0094] The filter 30 is folded at its periphery 31 between the two rings 60 and 70.

[0095] The lower ring 60 and the upper ring 70 are coupled by means of a snap fit.

[0096] Figures 4 and 5 show respectively the lower ring 60 and the upper ring 70 alone.

[0097] The upper ring 70 comprises coupling reliefs 71 and the lower ring 60 a corresponding annular groove 61 in which the coupling reliefs 71 are pressed.

[0098] The upper ring 70 and the lower ring 60 each comprise catch peaks 81 which pass into the filter 30. These catch peaks 81 have, for example, a pyramidal or conical shape and their height is comprised, for example , between 0.5 and 4 mm.

[0099] The latching peaks 81 of the upper ring 70 and the lower ring 60 may be located opposite each other. In this way, the filter 30 is held between the two rings 60 and 70 and is trapped in the two rings through the hooking spikes 81.

[0100] Lower ring 60 may comprise, as illustrated, a first radially inner support 62a, an intermediate support 62b, and a third radially outer support 62c.

[0101] Supports 62a and 62b are joined by a first annular wall 63a, and supports 62b and 62c are joined by a second annular wall 63b

[0102] The walls 63a and 63b are oriented perpendicular to the X axis, while the supports 62a, 62b and 62c are tubular and coaxial to the X axis.

[0103] The groove 61 is produced in the radially inner face of the support 62c. Spikes 81 are supported by wall 63a. The latter extends in a recessed manner from the upper edge of the supports 62a and 62b, so that the spikes 81 extend into an annular groove formed between the supports 62a and 62b, on the wall 63a. Spikes 81 do not protrude above this slot. The 62c bracket is taller than the others.

[0104] The upper ring 70 comprises a first tubular support 72a that connects with the upper part to a transverse wall 73. This first support 72a bears the coupling reliefs 71.

[0105] The upper ring 70 comprises a second support 72b, radially inside the first support, where the lower end of said second support 72b bears the spikes 81, and a third support 72c radially inside the second support 72b.

[0106] When the rings 60 and 70 are assembled, the third support 72c is located next to the first support 62a, the filter 30 being gripped between the two. The second support 72b is inserted into the slot formed between the supports 62a and 62b, on the wall 63a. The first support 72a is inserted between the supports 62b and 62c, and presses the filter 30 at its periphery 31 against the support 62b.

[0107] Wall 73 presses against the upper edge of support 62c.

[0108] The radially inner surface of the neck 13 comprises an annular groove 14 where the radially outer edge 91 of the upper ring 70 snaps shut.

[0109] The container 10 comprises a bottom 12, spherical in shape, which is concave towards the filter 30, for example with a radius of curvature of between 30 and 60 mm, for example 45 mm.

[0110] To use the device 1 the user removes the protective cover 40.

[0111] The user can then use an applicator 20 for the upper surface Ssup of the filter 30, as illustrated in Figure 6.

[0112] The user can simply use the applicator for the upper surface Ssup of the filter 30 with no movement of the applicator 20 other than by movement in contact with and then moving away from the filter 30, preferably by applying pressure on the latter during contact between the applicator 20 and filter 30, causing product P to deposit on applicator 20.

[0113] In a variant, at the time the product is collected, the user can rotate the applicator 20 or the upper surface of the filter 30 and/or move it in translation.

[0114] The user can load the applicator 20 as desired by pressure on the filter 30. In particular, the user can press on the filter 30 a number of times in a compression/relaxation cycle of the cellular material, to increase the load of the cellular material. filter 30 with product P.

[0115] Once the applicator has been loaded with product P, the user can gently touch his skin with the applicator 20 to apply the product P present in the applicator 20 to himself.

[0116] The user can blend the product P deposited in this way as much as necessary with the same applicator 20, moving it on the skin, or with the help of another applicator.

[0117] Figure 7 shows a variant of the device according to the invention, comprising a lower ring 60 having holes in the peaks 100 of the upper ring in which it is inserted, where the filter 30 is caught between the two rings and pierced by the peaks 100.

[0118] The filter 30 is schematically shown between the lower ring 60 and the upper ring 70 in Figure 7: the grip of the filter 30 between said rings and the corresponding deformation have not been reproduced.

[0119] Seal 24 is annular in the example in Figure 7.

[0120] The protective cover 40 can house a mirror 80.

[0121] Filter 30 may comprise through holes 35, as illustrated.

[0122] For example, the filter in Figure 1 may be provided with through holes. The one in Figure 7 may not have through holes.

[0123] Additional variants are possible. For example, filter 30 can be moved in container 10 along axis X to follow the drop in product level P when the latter is removed. In this case, it is fixed, for example, at its periphery to a rigid frame that slides in the housing containing the product.

[0124] The expression "comprising a" should be understood as synonymous with "comprising at least one".
