Description

[0001] DEVICE COMPRISING A SCREEN COMPRISING A CELLULAR MATERIAL [0002]

The present invention relates to a device for packaging cosmetics.

More specifically, the present invention relates to a device comprising a container for containing the product to be dispensed and a screen through which the product in the container can exit.

Various types of devices of this type are known which have screens with dispensing orifices having various shapes and arrangements and through which the product passes. The screen may or may not be a follwor, i.e. it may or may not fall in the container during dispensing of the product and emptying of the container.

Application CN202664613 discloses a device comprising a screen having a central dispensing orifice of a hexagonal cross section and a plurality of dispensing orifices disposed about the dispensing orifice and each having a major axis and a substantially elongated shape oriented substantially radially do.

[0005] JP 2003-79425 discloses a screen which is fixed by a grating fixed to a support frame provided with tabs that can be bent against the edge of the housing of the container holding the product when the screen falls in the container during the emptying of the container. And a device configured as described above.

Document FR 2815832 teaches a device comprising a closing element and an applicator placed against a compressible porous element that allows the applicator to be loaded into the article in the closed position of the closing element.

Document FR2856255 describes a cosmetic powder container comprising a separating element made of an elastic material through which cuts are formed. The cuts are closed when no mechanical pressure is applied and are opened by stretching the separating element so that cosmetic powder can pass through the separating element during use.

There is a need to further improve the packaging device comprising the screen in order to simplify the manufacture of the packaging device, especially the screen, and to improve the application of the product and / or the loading of the applicator.

The present invention relates to a cosmetic packaging device,

A container for containing cosmetics to be applied, and

- a screen comprising a deformable cellular material, the cosmetic being contained in said container passing through said screen,

The container includes a bottom portion, and the screen achieves this object by a cosmetic packaging device, which can contact the bottom portion of the container when all of the cosmetics in the container have been used.

The cellular nature of the materials making up the screen is particularly important in the case of open porosity where the product contained in the container, from the lower surface of the screen to its upper surface so that the user can pick up the product from the upper surface of the screen It can be easily passed through.

An appropriate amount of product can be picked up from the upper surface of the screen. In particular, the device allows to limit and control the amount of product picked up by providing an interface constituted by a screen between the user and a lump of product in the container.

The screen may retain a portion of the product in pores.

The cellular nature may also allow the screen to have a relatively rough surface desirable for shearing the product when the product is picked up, thereby allowing for a more homogeneous loading of the applicator.

The article can be picked up, for example, with a finger, a sponge, a flocked or unfloated plastic applicator, or a fine brush.

The ability of the screen to contact the bottom of the container when all of the product in the container is used makes it possible to almost completely empty the container of the product.

The screen may also shape itself into the shape of the bottom of the container when all of the product in the container is used.

The screen includes a lower surface oriented toward the article contained in the container, and an upper surface opposite the article contained in the container.

The maximum thickness between the lower surface and the upper surface of the screen is also referred to as the thickness of the screen and may also be referred to as the membrane.

The thickness of the screen may be 0.4 to 5 mm.

The area of the upper surface of the screen may be between 180 mm < 2 > and 3800 mm < 2 >.

Such an area of the top surface and such a thickness of the screen allows the user to have a large area for accessing the product while minimizing the amount of cellular material required and the amount of lead product hanging on the screen at the end of use.

Preferably, the screen is entirely constructed of cellular material.

Depending on the initial degree of filling of the container and whether the screen is a follower, the product contained in the container may or may not come into contact with the lower surface of the screen when no pressure is applied to the screen by the user.

Preferably, the screen hugs the surface of the product while the product contained in the container is picked up.

The screen is preferably elastically deformable. Thereby, if the product is not already in contact with the lower surface of the screen when no pressure is applied, the screen can be deformed under pressure exerted by the user such that the lower surface thereof contacts the product contained in the container. If the product is already in contact with the lower surface of the screen, it is easier to load the product on the screen and the amount of product available to the user on the upper surface of the screen increases.

The screen is made of polyurethane PU foam, polyethylene PE foam, EVA foam, PVC foam, impregnated PU foam, cellular EPDM rubber, cellular neoprene rubber, cellular nitrile rubber (NBR / PVC), compact neoprene rubber, hard EPDM rubber, (EPDM, neoprene, silicone), polyethers and / or polyesters, and in particular may also be composed of them.

The cellular material may be an open-cell material.

In a variant, the cellular material is a closed-cell material, and the screen then has one or more through orifices passing therethrough, the through orifices being produced, for example, by laser cutting.

If the material of the screen is an open-cell material, it is possible that the screen does not have any through-orifices produced by cutting or drilling.

The screen is preferably a single layer or multiple layers. For example, there is a plurality of material layers having different porosities.

With or without an open cell, the screen may have through orifices. The through orifices may each have a circular or non-circular shape, in particular a polygonal cross-section.

The through orifices may have a constant or non-constant cross-section through their thickness.

The through orifices may be produced by drilling and / or cutting, in particular by laser cutting.

The screen may be provided with cavities rather than through-cavities, especially when made of open-cell material, and the cavities are created, for example, by cutting, drilling or grinding. By locally reducing the thickness of the material, these cavities can help the product pass through the screen.

The screen may or may not be a follower.

The article is preferably a fluid.

The viscosity of the product may be 40 to 90 UD (Deviation Unit), preferably 55 to 80 UD, or 366 to 569 cP (centiPoises), or 0.37 to 0.57 Pa.s.

This viscosity is measured at 25 占 폚 with Rheomat 180 (Lamy) equipped with an MS-R2 spindle, selected for low to medium viscosity of the product, rotating at a speed of 200 revolutions per minute. The measurement is made after a rotation time of 10 minutes. Viscosity measurements are made at least one week after manufacture.

Such a viscosity makes it possible to improve the taking of the product from the upper surface of the screen and to prevent the product from flowing during use.

The product can be taken from the upper surface of the screen with the aid of an applicator. The applicator may include or consist of an applicator member such as a foam, brush, sponge, nonwoven, or flocked end piece.

In a variant, the product can be picked up with a finger by letting it pass over the screen.

The product is preferably a cosmetic. The cosmetic may be a foundation or a complexion corrector, a concealer product, or a care product.

The upper surface of the screen may be substantially flat at the portion through which the product passes during use. The lower surface of the screen may be substantially flat at the portion through which the product passes during use.

The thickness of the screen may be substantially constant at the portion through which the product passes during use.

The thickness of the screen may be substantially constant prior to incorporation into the device, and the screen is produced, for example, by cutting a disc from a film of cellular material.

The areas of the upper surface and the lower surface of the screen may be the same or different.

The device may include a protective cover that covers the screen when the product is not picked up.

The protective sheath may be secured to the body of the container by friction, screw-tightening, bayonet locking or snap-fastening.

In a variant, the protective cover can be articulated or connected to the body of the container by a sliding connection.

The device may not have an applicator accommodated between the protective cover and the screen. This simplifies manufacturing compared to the device containing the applicator, and provides the user with more freedom of choice for product application.

In one variation, the device may include an applicator to provide the user with a complete system.

The device may comprise a mirror, in particular a mirror housed in a protective cover.

The device may not include a wiper member from which the applicator is extracted.

The device may not include a bellow particularly in the container.

The screen may be secured at its periphery to the rest of the device, particularly at a distance from the bottom of the container which does not vary with the amount of product present in the container.

The screen may be secured 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 screen can be held between the upper ring and the lower ring, whereby the screen can be effectively retained.

The upper ring and the lower ring can be engaged with each other by snap-fastening or in some other way.

To this end, the upper or lower ring may comprise a coupling relief, or the upper ring may comprise an annular groove through which the coupling relief may snap-fasten.

At least one of the upper ring and the lower ring, more preferably both the lower ring and the upper ring, may include one or more catching spikes inserted into the screen to further improve retention of the screen by catching.

The container may include an annular groove for receiving the lower ring.

In one variant, the screen may be fixed at its periphery to the rest of the device by at least one ring overmolded with the screen.

In another variation, the screen may be secured to the remainder of the device by clamping it at its periphery between the container and the at least one retaining ring.

The container may include a relief, such as an annular groove, in which one of the upper or lower ring, particularly the upper ring, is snap-fastened.

The bottom of the container may have a concave shape toward the screen.

The bottom of the container may have a parabolic, elliptical or spherical shape.

The bottom of the container may be located at approximately the same level as the lower portion of the packaging and dispensing device.

The screen may contact the bottom of the container in a reversible manner when there is no product and when a corresponding pressure is applied from above to press the screen against the bottom of the container.

Preferably, the screen may be in contact with any point on the bottom of the container in a reversible manner when there is no product and when a corresponding pressure is applied from above to press the screen against the bottom of the container.

The container may include a rigid body.

The rigid body may be made by molding a thermoplastic material to have a cavity defining a space for holding the article.

The container may be a container other than the flexible sheet.

Another subject of the present invention is to provide

Loading the product into the applicator using the device according to the invention, and

- applying the product to the area to be treated of the human keratinous material.

The applicator may be loaded without moving the applicator in addition to moving the applicator away from the cousin and then moving it away (which may cause the product to lodge with the applicator).

In a variant, when the article is picked up, the user can rotate and / or translate the applicator while in contact with the screen.

The product may be taken by tapping the applicator or finger lightly on the screen or by friction.

The invention may be better understood by reading the following description of non-limiting examples of the invention and reviewing the accompanying drawings.
