Description

Cosmetic product

Technical Field

The present invention relates to the field of cosmetics, and more particularly, but not exclusively, to cosmetic preparations intended to make up or care for human keratin materials, in particular the skin.

Background

It is known to impregnate a porous structure with a cosmetic composition, with which a finger or an applicator can be brought into contact to load the product into the porous structure.

Many patent application publications relate to cosmetic articles of this type.

In particular, application WO 2017/016608 a1 may be cited, which discloses an article comprising a fibrous mat consisting of a nonwoven fabric covered on one face with a screen.

The problem posed by this type of article is that it is necessary to find a compromise between various parameters, such as the ability to store a large quantity of composition and to recover it gradually and as completely as possible during use, as well as the need to benefit from shape memory and the ability to receive compositions with variable viscosity, all of which have small overall dimensions and manufacturing costs compatible with the requirements of mass-distribution.

Disclosure of Invention

The present invention aims to further improve cosmetic preparations having a reservoir containing a cosmetic composition.

According to a first aspect of the invention, the invention achieves this object by means of a cosmetic article having a reservoir with a first layer and a second layer connected together by a set of filaments forming a spacer, the ends of the set of filaments being connected to the first layer and the second layer respectively, the first layer being permeable at least to a cosmetic composition, the first layer and the second layer being able to retain at least some of the compositions between each other, in particular when the article is in use.

Another subject of the invention is an article having a cosmetic composition at least partially comprised, in particular mostly comprised, between a first layer and a second layer.

The reservoir according to the invention has a free space for the composition between the first layer and the second layer, and this free space can be relatively large, since a relatively small amount of filaments can suffice to ensure the spacing function. Thus, the capacity of the reservoir to store the composition is relatively large. This allows, if desired, to obtain a thinner reservoir containing an equal amount of the composition than some known reservoirs.

Furthermore, by adjusting the length and number of the filaments and their material, the elastic properties of the reservoir can be controlled relatively precisely, so that the deformation of the reservoir under load can be controlled when collecting the product. The reservoir can thus be easily adapted to the nature of the composition and of the keratin materials to be treated. The filaments can be elastically deformed and ensure good properties of returning to the original shape immediately after collection is completed.

The invention also allows a wide choice of materials, textures and porosity of the first layer. Thus, the first layer can be easily adapted to the nature of the composition and the desired feel. For example, for very fluid compositions, a fine mesh fabric may be used as the first layer, which provides a strong resistance to passage of the composition. For more viscous compositions, larger mesh fabrics may be used which allow easier passage of the product.

If desired, the present invention may also maintain compositions that are more viscous than those typically allowed for foam reservoirs, e.g., having a viscosity of 200 seconds measured at 25 ℃ and atmospheric pressure^-1Greater than or equal to 4.5pa.s and less than or equal to 100pa.s at a shear rate (measured using a Brookfield Rheomat RM 180 viscometer equipped with spindle No. 4, after 10 minutes of spindle rotation, to stabilize the rotational speed and viscosity). The viscosity is 200s^-1Can of course be less than 4.5pa.s, for example from 1mpa.s (or 1CPo) to 4.5pa.s (measured after 10 minutes of spindle rotation using a brookfield rheomat RM 180 viscometer equipped with spindle No. 4 to stabilize the rotational speed and viscosity).

The first and second layers may also be joined together over all or a portion of their peripheries, particularly by peripheral welding or peripheral stitching.

The composition may be liquid at 25 ℃, i.e. flowing under its own weight.

The first layer may appear substantially continuous to the unaided eye. The term "visually apparent" is understood to mean observed with the eye of normal acuity at a distance of 15 cm. In a variant, the first layer appears to be perforated to the naked eye.

The first layer may be a braid, in particular a braid having a needle count of 16 to 22. The entire structure is advantageously produced by weaving.

Preferably, the first layer (particularly when it defines the surface on which the user collects the product) is less perforated than the second layer. The second layer may face the bottom of the housing containing the article and therefore not be used to collect the composition. The fact that the second layer is perforated makes it easier to initially load the reservoir with the composition when loading is performed by pushing the article without the composition (first layer up) into the housing filled with the composition.

The presence of perforations in the second layer also reduces the number of filaments connecting the first and second layers, since the filaments start from non-perforated areas of the second layer, so that the free volume capable of holding the composition can be increased.

The composition may be contained in the reservoir in an amount greater than 50% by weight at least at a given time during use of the article. As many perforations as desired can easily be produced in order to increase the capacity of the reservoir, compared to the fibre mat disclosed in application WO 2017/016608 a 1.

All of the compositions may be contained in the reservoir at the time of initial use. In other words, the user is provided with a product having a reservoir containing all of the composition to be applied. In one variation, the user loads the reservoir with the composition at the time of initial use by pushing the reservoir into the housing initially containing the composition. When the reservoir reaches the bottom of the housing, most or all of the composition is then contained in the thickness of the reservoir.

Typically, the maximum dimension of the perforations may be 1mm to 15 mm. The cross-sectional area of each perforation may be 1mm²To 100mm². All perforations are preferably of the same shape.

The thickness of the reservoir, measured between the opposing faces of the first and second layers, may be from 1mm to 25mm, preferably from 3mm to 20mm, even more preferably from 5mm to 15 mm. The thickness is preferably from 1mm to 15mm for cosmetic applications and from 5mm to 25mm for care applications.

The filaments may have at least one portion oriented perpendicular to the first and second layers. In one illustrative embodiment of the invention, the filaments each have an arcuate shape. This may give the reservoir greater compressibility and reduce the force applied to move the first and second layers towards each other. Preferably, the filaments are monofilaments rather than multifilaments or filaments made from spun fibers. This gives the filament more rigidity, thereby contributing to the elasticity of the reservoir and its shape memory. The length of the filaments is preferably greater than or equal to 3 mm.

The reservoir is preferably made entirely of synthetic material, preferably thermoplastic. For example, the reservoir is made of polyester, polyamide, polyolefin, among other plastic materials.

The reservoir may comprise intersecting filaments when viewed in a direction perpendicular to the thickness of the reservoir. When a user presses on the first layer, this may cause the first layer to move toward the second layer without any lateral offset of the first layer relative to the second layer.

The first and second layers are preferably fabric layers and are preferably constructed of braided wire. In particular, the filaments forming the spacer are advantageously connected to the first and second layers by weaving.

The first and second layers may be produced by weaving on a loom with twice the spacing between needles. It may be a warp knit, which cannot be unraveled, or a weft knit.

In top view, the reservoir may have an occupation of 2cm²To 80cm²Of (2) is provided.

The outline of the reservoir may be circular, but other shapes are also possible, in particular polygonal shapes. Shaping can be performed by cutting, in particular (as the case may be) using a punch or a laser.

In an illustrative embodiment of the invention, the first layer is lined with a third layer that is permeable to the composition. The presence of this third layer is very particularly advantageous when the first layer has perforations of non-negligible dimensions, since it improves the distribution of the composition on the outer surface of the reservoir, said outer surface being defined by this third layer.

The third layer may or may not be textured. The third layer may be selected from woven and non-woven fabrics.

According to the invention, the cosmetic composition present in the article is preferably largely comprised between the first layer and the second layer.

The expression "mostly comprised between the first layer and the second layer" means that 70% to 100% by weight, advantageously 80% to 100% by weight and more advantageously 90% to 100% by weight of the cosmetic composition is comprised between the first layer and the second layer, with respect to the total weight of the cosmetic composition in the article.

Preferably, the article according to the invention has no intermediate absorbent structure, in particular foam, attached between the first and second layer. Thus, the cosmetic article is preferably free of foam between the first and second layers. More preferably, the article according to the invention has a single first layer and a single second layer.

The cosmetic article according to the invention is advantageously free of any foam layer, such as, for example, PU foam, SBR foam or polyolefin foam.

The cosmetic composition may be chosen from cosmetic compositions or care compositions, for example from foundations, blushes, eye shadows, sun screens.

According to another aspect of the present invention, a further subject of the present invention is a beauty kit, in particular for cosmetics, having a body holding a reservoir according to the present invention and a cover movable with respect to the body (for example hinged on the body).

Upon initial use of the kit by the user, the reservoir may be completely filled with the composition. In one variation, the composition is contained in the body and the reservoirs are individually packaged or not individually packaged in a kit. The film seal may close the housing containing the composition. For initial use, the user may remove the membrane seal and install the reservoir in the housing. By pressing the reservoir into the bottom of the housing, the user ensures that the reservoir is loaded with product.

Another subject of the invention is an assembly comprising an article according to the invention and a kit, a refill or a pouch.

The kit has, for example, a body for holding the article and a cover for preventing entry into the article when it is not in use. The cover may close the cartridge in a sealed manner or in an unsealed manner. The article is carried by a tray, for example, and the body of the cartridge is configured to hold the tray. The article with the tray may form a refill, which may be packed in a box or pouch, for example.

The body of the kit is made of, for example, a thermoplastic material.

The cover of the cartridge may be screwed or hinged to the body. A snap-fit system or a magnetic lock system may be provided to hold the cartridge in the closed configuration.

The kit may have a mirror and a housing for holding a cosmetic applicator, if desired.

In top view, the cover may have a rectangular, oval, circular or other profile.

The articles may be retained in the kit by any means, such as by a retaining ring attached to the body of the kit.

The sleeve may have an exterior surface that has been decorated in various ways (e.g., metallized, painted, screen printed) or in some other way.

The alternative may comprise the article in the form of: it is necessary to mount the refill on the kit so that the user can use the article to collect the composition with the article.

The alternative may have an article holding tray made of plastic. The height of the tray may be greater than the height of the article or, in a variant, less than the height of the article.

When assembled, the tray may define the bottom of the cartridge on the side opposite the cover.

The article may also be placed directly in the body of the kit, rather than being carried by a tray attached to the body of the kit.

The disc may be secured to the body of the cartridge by snap-fitting, friction or screwing.

When the article is contained in a pouch, the article may be placed in a tray and form a replacement. In a variant, the pouch comprises the article alone and, where appropriate, the composition. The pouch may be made of a thermoplastic material, optionally metallized. The pouch may be closed by heat sealing. The pouch may have a notch which constitutes the starting point for the tear and is therefore easier to open.

The pouch may comprise a polyolefin.

The pouch may be sealed to avoid any evaporation of the volatile components of the composition.

According to another aspect of the invention, another subject of the invention is a cosmetic process comprising the following steps: the composition is collected on the reservoir of the preparation according to the invention as defined above, and the composition is applied to the human keratin materials, in particular the skin, the application of the composition to the human keratin materials being carried out with the aid of an applicator. During collection, the user may deform the filaments to move the first and second layers toward each other.

Detailed Description

As shown in fig. 1, a cosmetic article 1 according to the present invention has a kit 2, the kit 2 having a body 3.

The cartridge 2 also has a cover 5, which cover 5 is for example hinged on the body 3 or otherwise fixed, for example screwed, on the body 3.

The cartridge 2 contains an applicator holder 6, which applicator holder 6 is for example an element hinged around the same axis of rotation as the lid 5 on the cartridge body 3.

The applicator 7 is for example of the puff type, for example constituted by a foam sponge.

In the example in question, the disc 4 is housed in the housing 8 of the body 3 of the cartridge. The tray 4 houses a reservoir 10.

The cartridge 2 has an annular lip 9 reaching above the disc 4, the lip 9 having an edge folded towards the bottom of the disc 4 to hold the reservoir 10 in place.

According to the invention, the reservoir 10 has a first fabric layer 11 and a second fabric layer 12, the first fabric layer 11 and the second fabric layer 12 being connected together by a set of filaments 13, as can be seen more particularly in fig. 2 and 3. Such a reservoir can be manufactured by weaving according to the teachings in application WO2012/153131a1 or EP 1863959. These layers are manufactured by weaving a synthetic material. An example of a possible suitable fabric structure is a commercially available fabric structure for textile applications under the designation "SPACER FABRICS" (space FABRICS).

The thickness e of the network of filaments 13 forming the spacer is, for example, 1mm to 25mm, preferably 3mm to 20mm, more preferably 10mm to 15 mm. The length of the filaments 13 is particularly preferably greater than or equal to 3 mm.

According to the invention, the reservoir 10 contains a composition C which is contained for the most part inside the reservoir 10, in particular entirely in the reservoir.

The first layer 11 may be a fine mesh layer, as shown, such that it constitutes a filter that tends to slow the expulsion of composition C from the reservoir 10 when the user presses the reservoir 10 with their finger or the applicator 7 to collect the product.

The second layer 12 has a less dense structure with perforations 14, which perforations 14 facilitate the passage of composition C, in particular when the reservoir 10 is assembled in the disc 4 (when the disc contains composition C). During this operation, the reservoir 10 is pressed in the direction of the bottom of the tray. The presence of the perforations 14 allows the composition to more easily penetrate into the free space 16 between the first layer 11 and the second layer 12.

In particular, fig. 6C shows that, in the region of the perforation 14, a larger space is available within the reservoir, since the filaments 13 are only connected to a solid portion of the second layer 12.

The filaments 13 may be imparted with various orientations within the reservoir 10. For example, as shown in fig. 6A, the wires 13 may all be substantially curved in substantially the same manner and, for example, have concave surfaces pointing in the same direction.

In a variant, as shown in fig. 6B, the wires 13 intersect, that is to say there are wires 13a and 13B having concave faces facing in opposite directions. This allows the first layer 11 to deform along the axis of the disc 4 when the user presses the first layer 11.

A wide variety of shapes and sizes may be given to the perforations 14.

The structure comprising the two layers connected by the filaments 13 forming the spacers may be shaped by cutting, for example by means of a punch element or a laser.

The invention is not limited to the particular materials used to produce the first and second layers and the filaments.

For example, polyamide thread, polyolefin thread (in particular polypropylene thread) or polyester thread may be used.

A mixture of wires made of different materials may be used.

Various treatments, such as abrasion treatments, may be applied to the first layer 11 to make the surface softer.

As shown in fig. 7, at least one upper layer 15 (e.g., a woven or non-woven fabric) may also be attached to the first layer 11, the at least one upper layer 15 being permeable to the composition C. In this case, it is advantageous to produce the first layer 11 with perforations 16, said perforations 16 being of a size, for example, comparable to the perforations 14 in the second layer 12, in order to make it easier for the product to reach the upper layer 15.

The upper layer 15 is for example glued to the first layer 11 or otherwise fixed (for example by welding or stitching).

Layer 15 may be textured depending on the desired feel to layer 15. For example, the third layer is embossed.

In one variant, several structures 10 are superimposed on each other. The structure 10 may also be folded upon itself.

The invention is not limited to the examples that have been described.

Shown in fig. 8, in a variant that can be combined with the example (in particular the example of texture, material and visual appearance described above) is the choice of a first layer 11 and a second layer 12 joined together at the periphery 18, in this example the first layer 11 and the second layer 12 are joined together by welding, but other types of joining, such as stitching, are conceivable. The entire periphery 18 of the first layer 11 and the second layer 12 may be connected as in the illustrated example, or the periphery 18 of the first layer 11 and the second layer 12 may be only partially connected. Also in this example, the filaments 13 have a length of at least 3 mm.

In particular, the reservoir may be mounted in a kit made in some other way.
