Description:
ARTICLE SUCH AS A POWDER PUFF

Field of the invention

The present invention relates to the field of cosmetics and more particularly but not exclusively to cosmetic articles intended for making up or caring for human keratin materials, notably the skin.

Technological background

For applying a cosmetic product to the skin, various applicators are known.

These include sponges, brushes, wipes and flocked applicators.

There is a need for a new applicator that allows the user to enjoy a new sensory experience, and which offers good properties for applying a cosmetic composition.

Summary of the invention

The invention therefore relates to an article such as a powder puff for applying a cosmetic product, comprising a first layer and a second layer joined together by a collection of filaments forming a spacer of which the ends are connected to the first layer and to the second layer, respectively.

In a first embodiment, the first layer and the second layer are made of a textile material which can be selected from wovens, nonwovens and knits.

In a second embodiment, the first layer and the second layer are made of a foam.

The article is not impregnated with cosmetic product prior to first use. It is used to pick up cosmetic product from an independent reservoir and apply it, notably to the skin, or to remove or blend a cosmetic product present on the skin. It does not constitute a reserve of cosmetic product.

The article according to the invention is supple and pleasant to touch.

By virtue of the invention, a new applicator with a spring effect associated with the presence of the spacer between the first and second layers is available. The spacer gives the article thickness without offering significant resistance to pressure and confers a feeling of comfort associated with the softness thus obtained.

For preference, the article is free of foam between the first and second layers.

The article may be mounted on a support, notably in such a case being in the form of an end piece. The support may constitute a member for holding, such as a stem. As an alternative, the article is not mounted on any support. All or part of the article, notably the collection of filaments that form the spacer, may have undergone an antibacterial treatment.

The article may be washable. The spacer constitutes an aerated space, which means that the article dries quickly.

The article advantageously comprises a fastening, advantageously peripheral, joining at least the first and second layers together at their periphery. The fastening is achieved for example by ultrasonic or high-frequency welding. In that case, the spacer is enclosed inside the article by the fastening and is not visible from the outside. Such a fastening, notably welding, makes it possible to prevent the textiles and/or foams that form the first and second layers from coming undone at their periphery. It also makes it possible to make the application gentler for the user.

The article may comprise at least one supple third layer, notably textile, attached to an exterior face of the first and/or of the second layer.

The third layer may be fixed to the first and/or to the second layer. For example, the third layer may be bonded to the first and/or to the second layer, the article comprising a layer of adhesive applied to the first and/or to the second layer, for example applied by spraying, screen printing, coating or some other method. The third layer may then be bonded to this layer of adhesive.

As an alternative, the third layer may be fixed to the first and/or to the second layer by stitching, welding, bonding then welding, or any other suitable fixing means. In another alternative form, the third layer is not bonded to the first and/or the second layer but is merely fixed to the periphery of the article by welding, for example by ultrasonic or high-frequency welding. This welding is advantageously performed at the same time as the welding that joins the first and second layers together. The third layer is thus advantageously fixed, for example by welding, notably high-frequency or ultrasonic welding, at its periphery, to the first and second layers simultaneously.

As an alternative, it is not fixed to the first and/or the second layer. For example, the third layer covers each of the first and second layers and is fixed, for example at least partially by welding, at its periphery in such a way as to form a cover covering the rest of the article. All or part of the fixing of the third layer may then be able to be opened so that the cover is removable from the rest of the article. In particular, part of the fixing may be achieved using a fastener of the Velcro® type. That may prove advantageous for detaching the cover formed by the third layers from the rest of the article for the purposes of cleaning or replacement or if, for example, the cover is reversible.

The third layer may or may not be textured. The third layer may be chosen from wovens, nonwovens and foams. The third layer may contain threads of microfibres, notably of polyamide and/or polyester, or acrylic or the like, so as to confer additional softness to the touch. The third layer may be made of foam, for example of polyurethane or polyethylene foam, with closed cells or open cells, preferably with closed cells. When the foam is a closed-cell foam, that may make it possible to form a barrier and prevent the inside of the article from becoming soiled.

The article may comprise at least one weld over all or part of its thickness in a region distinct from its periphery. Such a weld may make it possible to delimit a region for holding or a region for applying cosmetic composition or make it possible to create one or more pattem(s) on the article.

The article may have a circular, oval, square, rectangular, trapezoidal shape, the shape of any regular or irregular polygon, or another shape. The article may have a surface which, when viewed from above, occupies between 2 and 80 cm 2 . The shaping may have been effected by cutting, notably using a punch or laser, as appropriate. The article may be manufactured with the cutting-out and welding at the periphery being performed simultaneously, for example by ultrasound or high frequency.

In particular, the third layer may have been cut out and welded, by ultrasonic or high-frequency means, to the first and/or the second and/or some other third layer, without having been bonded beforehand to the first and/or the second layer that it covers. As an alternative, the third layer may have been coated with adhesive before having been cut out and welded, by ultrasonic or high-frequency means, to the first and/or the second layer that it covers.

The longest dimension of the article, notably of the powder puff, may be comprised between 10 mm and 100 mm, preferably being comprised between 40 mm and 60 mm.

The invention allows for a wide choice of materials, textures and porosities for the first layer and for the second layer and, where appropriate, for the third layer. These may thus easily be adapted to suit the feel and type of makeup desired. When the first, the second and/or the third layer comprise(s) a textile, the textile forming the first layer, the second layer and/or the third layer comprises for example threads made with fibres and/or micro fibres selected from the group consisting of: synthetic fibres and/or microfibres such as polyamide, elastane, polyester, acrylic, viscose, acetate, natural fibres and/or microfibres such as silk, wool, cotton, linen, hemp, and mixtures thereof. The textile preferably comprises a mixture of synthetic fibres and/or microfibres, particularly polyamide and elastane, the proportion of polyamide notably being greater than 50%, preferably greater than 60%, notably greater than 70% by weight. The textile comprises for example a mixture of threads made of polyamide and elastane micro fibres. The textile may have undergone a surface treatment, for example an embossing.

When the first, the second and/or the third layer comprise(s) a foam, this may be selected from the group consisting of polyurethane, butadiene rubber (BR), styrene- butadiene rubber (SBR), natural rubber (NR), wetted urethane, dry urethane, polyether, polyester, polyvinyl chloride, polyethylene, ethylene vinyl acetate (EVA), latex, silicone, styrene-isoprene-styrene (SIS), polyvinyl alcohol (PVA), silicone elastomer, nitrile rubber, butyl rubber and neoprene.

Such a foam may be a closed-cell foam. As an alternative, it is an open-cell foam.

The material or materials of which the first, second and/or third layers are made are preferably chosen to give the article a silky feel. The material or materials of which the first, second and/or third layers are made may be chosen to give the first, second and/or third layers elasticity.

The first layer and/or the second layer and/or the third layer may appear to the naked eye to be substantially continuous. The expression“to the naked eye” should be understood as meaning viewed at a distance of 15 cm with an eye of normal acuity. As an alternative, the first layer and/or the second layer and/or the third layer appears to the naked eye to be perforated. In that case, the first layer and/or the second layer and/or the third layer comprises at least one perforation, notably a plurality of perforations.

The perforations may be of non-polygonal shape, for example of circular, oval, ogive, oblong, shape. In particular, the perforations may have a shape that includes at least one rounded portion. All of the perforations may be of the same shape. The perforations may be distributed uniformly over the layer.

In general, the largest dimension of a perforation present on the first, the second and/or the third layer may be between 1 mm and 15 mm. The cross-sectional area of each perforation may be between 1 mm 2 and 100 mm 2 .

The first layer may be made from the same textile and with the same weave or knit or from the same foam as the second layer and/or the third layer.

As an alternative, the first layer is made from a different textile and/or with a different weave or knit compared with the second layer and/or the third layer. In the latter instance, that makes it possible to obtain different makeup effects. As an alternative, one of the layers is suited to the application of cosmetic product, notably to the skin, whereas the other of the layers is more suited to finishing or blending the makeup. As an alternative, one of the layers is suited to the application of a liquid cosmetic product, whereas the other layer is suited to the application of a powdery cosmetic product. The same is true of the third layer that covers the first and/or the second layer. The third layer that covers the first layer may be identical to or different from the third layer that covers the second layer.

The colours of the various layers may be the same as each other or different.

The thickness of the article, notably of the powder puff, measured at the centre thereof between the opposing faces of the first and second layers, may be between 1 mm and 30 mm, better still between 5 mm and 25 mm. For makeup application, a thickness of between 1 and 15 mm may be preferred, and for care application, a thickness of between 5 and 30 mm may be preferred.

The thickness of the or each layer out of the first, the second and/or the third layer, notably when this/these layer(s) comprise(s) a foam, may be comprised between 0.1 and 2 mm, notably between 0.2 and 2 mm, or even between 0.3 and 1 mm, preferably between 0.3 and 0.5 mm, and notably equal to 0.35 mm. The foam layer is thus of relatively fine thickness, which offers a number of advantages, notably of being easier to weld, less expensive, supple and deformable, of offering a soft touch, notably when the cell density is high.

The filaments of the spacer may have at least one portion that is oriented perpendicularly to the first and second layers. In one illustrative embodiment of the invention, the filaments each have an arched shape. This can give the powder puff greater compressibility and reduce the force that has to be exerted in order to move the first and second layers towards one another. For preference, the filaments are each single-fibre filaments, rather than multi-fibre filaments or filaments made by spinning fibres. This gives them greater rigidity and thus contributes towards the elasticity of the powder puff and its shape memory.

The article, notably the powder puff, is preferably made entirely of a synthetic material, preferably thermoplastic. For example, the article, notably the powder puff, comprises at least one material selected from polyester, polyamide, a polyolefin, among other plastic materials.

The article, notably the powder puff, may comprise filaments that intersect when it is viewed in a direction perpendicular to its thickness. This can cause the first layer to move towards the second when the user presses the first layer, without any lateral offsetting of the first layer with respect to the second.

The first layer and the second layer are for example made of textile, being preferably made of knitted threads. In particular, the filaments forming a spacer are advantageously joined to the first and second layers by knitting. The filaments themselves may be knitted. The first layer and the second layer may be produced by knitting, on a loom with a double needle bed. It may be warp knitting that is unable to unravel, or weft knitting.

For preference, the article according to the invention does not have an intermediate absorbent structure, notably such as a foam, attached between the first and second layers. The article, notably the powder puff, advantageously does not have any intermediate layer of foam, such as PU, SBR or polyolefin foam, for example, between the first and second layers.

Cosmetic kit

A further subject of the invention is a cosmetic kit comprising a package comprising at least one, notably at least two, articles, notably powder puffs, as defined above. The package may consist of a sachet or a cardboard box.

The sachet may be made of a thermoplastic material, possibly metallized. The sachet may have been closed by heat sealing. The sachet may have a notch that constitutes the start of a tear, making it easier to open. The sachet may comprise a polyolefin. The sachet may be hermetically sealed. Cosmetic device

Yet another subject of the invention is a cosmetic device comprising at least one article such as a powder puff, as defined above, and at least one cosmetic composition to be applied using the article.

The cosmetic composition may be chosen from makeup or care compositions for the body or the face, for example from foundations, rouges, eyeshadows, sun protection creams.

The cosmetic device may also comprise a case comprising a reservoir of cosmetic composition and a housing for the article. The housing may be produced in such a way that the article is not in contact with the cosmetic composition inside the case.

The case may comprise a body comprising the reservoir, and a lid. The housing for the article may be provided in the case between the body and the lid, on top of the reservoir. The article may be free inside the housing. The lid of the case may be screwed or hinged on the body. A snap-fastening or magnetic locking system may be provided to keep the case in the closed configuration. The lid may have a rectangular, elliptical, circular or other contour when viewed from above. The case is made for example of a thermoplastic material.

The case may, if appropriate, bear a mirror.

The case may have an outer surface that has been decorated in various ways, for example metallized, painted, screen printed, or decorated in some other way.

Makeup method

A further subject of the invention, according to another of the aspects thereof, is a makeup method, comprising the steps of using the article, notably powder puff, according to the invention, to pick up a cosmetic composition from a reservoir and of applying it to human keratin materials, notably to the skin, using the article.

Detailed description of embodiments

In the rest of the description, identical elements or elements having identical functions bear the same reference sign. In order to make the present description concise, they are not described for each of the figures, only the differences between the embodiments being highlighted.

The article 1 according to the invention, depicted in Figure 1, constitutes a powder puff. This powder puff comprises a textile first layer 11 and a textile second layer 12. The first and second layers are joined together by a collection of filaments 13 forming a spacer of which the ends 14 and 15 are connected to the first layer 11 and to the second layer 12, respectively.

In this example, the powder puff 1 is not mounted on any support, and in itself forms an applicator to apply or remove a cosmetic product or to blend same. The powder puff 1 comprises a peripheral fastening produced in this example by ultrasonic welding. This peripheral fastening assembles the first layer 11 to the second layer 12 at their periphery 16 so as to ensure that the filaments 13 that form the spacer are not visible from the outside.

Supple layers l7a and l7b in this example respectively cover the first layer 11 and the second layer 12.

The layers l7a and l7b are also welded at their periphery to the first and second layers 11 and 12.

The powder puff 1 illustrated in Figure 2 has, in front-view, an ovoid outline. The length Ll of the powder puff 1 in this example is 58 mm, and the width L2 is 47 mm.

The powder puff 1 may have a different shape from the one illustrated in Figure 2 without departing from the scope of the invention. In particular, the powder puff 1 may have a circular, cylindrical, spherical, square, rectangular, oval, trapezoidal shape or any other polygonal or non-polygonal shape.

The layers l7a and l7b are, in this example, bonded respectively to the first and second layers 11 and 12. However, it would not constitute a departure from the scope of the invention if the layers l7a and l7b were fixed to the first and second layers 11 and 12 in another way, for example by stitching, welding, bonding of PU foam, spraying of adhesive, or by incorporating hotmelt threads into the first/second layer or into the layer l7a/l7b and then heating to effect bonding.

The first layer 11, the second layer 12 and the collection of filaments 13 may be manufactured in synthetic materials by knitting according to the teachings of application WO 2012/153131 Al or EP 1 863 959. Examples of textile structures that may be suitable are marketed for textile applications under the name of“SPACER FABRICS”.

The length of the filaments 13 that form the spacer is for example between 1 and 25 mm, better still between 6 and 10 mm.

The invention makes available a powder puff that can be washed, with a spacer that constitutes an aerated space, so that it dries quickly. The power puff may undergo an antibacterial treatment.

The powder puff 1, by virtue of the presence of the spacer, offers a spring effect. The resistance of the spacer to pressure is low, which means that in use, the user has the impression of comfort and softness. It is possible to choose a large number of textile materials, notably fabrics, woven, knitted and/or nonwoven, and/or of foams from which to make the first layer 11 , the second layer 12 and the layers l7a and l7b. In particular, the first layer 11 or the second layer 12 is preferably made from a woven or a knit. The layers l7a and l7b are preferably made of a foam, for example a closed-cell polyurethane foam. When produced by knitting, the layer(s) may be produced notably using warp knitting that is unable to unravel, or using weft knitting. The filaments 13 that form the spacer are advantageously connected to the first and second layers 11 and 12 by knitting.

In the example illustrated, as visible in Figure 3, the first layer 11 is produced with small oval-shaped perforations 21.

The second layer 12 illustrated in Figure 5 has large perforations 20 of oblong shape having a longest dimension L of between 1 mm and 5 mm.

The first and second layers may be identical.

At least one of these layers may be free of perforations, notably if the article is washable. The first and/or the second layer may comprise jacquard patterns.

The layer l7a may have a more close-knit structure, as visible in Figure 4. In this example, the layer l7b is identical to the layer l7a. The layers l7a, l7b advantageously comprise threads of polyamide microfibres so as to give the powder puff 1 a silky feel, in order to further enhance the user’s sensory experience. They also preferably comprise elastane fibres, so as to give the powder puff 1 elasticity.

The type of mesh structure of the various layers 11, 12, l7a, l7b is adapted to suit the desired use. In this example, the layers l7a and l7b are the layers with which the user will be in touch contact.

In an alternative, the layers l7a and l7b may be different. One may be suited to applying the cosmetic product whereas the other may be suited to blending the cosmetic product, once it has been applied to the keratin materials.

The filaments 13 may be oriented in various ways. In the example illustrated, the filaments 13 intersect, that is to say that there are filaments l3a and 13b which have concavities facing in opposite directions.

In the example illustrated in Figure 6, the filaments 13 are all curved in substantially the same way, with a concavity always facing in the same direction. Still in this example, the layer l7b is not present, the second layer 12 constituting an outer layer of the article. The user will be in contact with the second layer 12 on one side of the powder puff and with the third layer l7a on the opposite side.

In the example of Figure 7, the powder puff 1 does not have the layers l7a and l7b and by way of outer layers comprises only the layers 11 and 12.

In the example of Figure 8, the article 1 constitutes an end piece 30 mounted on a support 31 constituting a member for holding, in this example in the form of a stem.

Figure 9 depicts a kit 40 of cosmetic articles according to the invention, comprising a package 41 housing a plurality of powder puffs 1. The package 41 is a thermoplastic sachet closed by heat sealing, the closure zone 42 being visible in this figure.

Figure 10 depicts a cosmetic device 50 according to the invention, comprising a case 2 comprising a body 3 housing a reservoir in the form of a material impregnated with cosmetic composition C.

In this example, an annular lip 9 holds the reservoir in place.

The case 2 comprises an applicator holder forming a housing 6 to accept the powder puff 1, as illustrated. The applicator holder may be hinged to the body 3. It separates the powder puff 1 from the cosmetic composition and prevents these from coming into contact with one another inside the case.

The case 2 also comprises a lid 5 hinged to the body 3. The interior surface of the lid 5 is fitted with a mirror 45.

In order to perform a makeup or care operation, the user takes hold of the powder puff 1 in his/her fingers and uses it to pick up cosmetic composition C from the reservoir, and apply it to the skin.

Other alternative forms of article 1 are possible, notably with different shapes, different textile materials forming the first, second and other layers, different spacer forming of filaments, different shapes of support.

Figure 11 depicts an example of an article 1 in which the third layers l7a and l7b are made of foam, notably of closed-cell polyurethane foam. The thickness of each layer of foam is approximately 0.35 mm, and because of this small thickness is perfectly able to conform to the shape of the underlying layer 11 or 12. The foam advantageously has a high cell density in order to give it a silky feel that the user finds pleasant. In this example also, the third layers l7a and l7b are coated with adhesive and then cut and welded ultrasonically at the periphery 16. It will not constitute a departure from the scope of the invention if the third layers l7a and l7b are not bonded but only welded.

In the example of Figure 12, the article 1 comprises a first layer 11 and a second layer 12 which are made of thin foam, for example of a polyurethane foam 0.3 mm thick.

The example of an article 1 in Figure 13 illustrates the possibility of producing an at least partial weld 25, positioned in a non-peripheral region of the article 1. In this example, this weld makes it possible to delimit a region 26 for holding of the article 1.

In Figure 14, the article 1 comprises layers l7a and l7b made of foam which are neither bonded nor fixed to the first and second layers 11 and 12 but which are fixed to one another at their periphery, for example by partial welding. One portion 28 for the fixing-together of the layers l7a and l7b is thus fixed, by virtue of the weld, while another fixing-together portion 29 is removable, being fitted with Velcro® strips. The layers l7a and l7b thus form a removable cover 27, allowing it to be detached from the rest of the article 1 so that it can be washed or replaced for example. The cover 27 may even be reversible.

In Figure 15, as in the example of Figure 7, the powder puff 1 has by way of outer layers only the layers 11 and 12. In the example of Figure 15, a weld has been created at the periphery 16, for example using ultrasonic or high-frequency welding.

In the example of Figure 16, a layer 32 of adhesive, for example of a glue, is applied to the layer 11 then the layer l7a is fixed to the layer 11 by adhesive bonding. The layer 32 of adhesive is for example applied by spraying, by screen printing, by coating or by another method. Of course, it would not constitute a departure from the scope of the invention if the layer 12 were also coated with a layer of adhesive to which a layer l7b were externally fixed.

In the embodiment of Figure 17, the layer l7a is not fixed by bonding to the layer 11; a space between the layers l7a and 11 can be seen in this figure. By contrast, the layer l7a is fixed at the periphery 16 by welding, for example ultrasonic or high-frequency welding. This welding is advantageously performed at the same time as the welding that joins the layers 11 and 12 together. Of course, it would not constitute a departure from the scope of the invention if the layer 12 were externally covered with a layer l7b fixed in the same way as the layer l7a.
