Description

Assembly for packaging and application of liquid cosmetics

The present invention relates to an assembly for packaging and application of liquid cosmetics.

The expression "cosmetics" is understood to mean any cosmetics as defined in Regulation (EC) No 1223/2009 of the European Council of 30 November 2009, European Union Congress on Cosmetics.

The assembly for packaging and application is more particularly intended for the application of cosmetics to human keratinous surfaces such as skin, lips or nails.

Is also used in make-up and / or care of the skin and / or lips and is also satisfactory in terms of application, comfort, wear properties and coverage as well as make-up effects such as gloss The development of formulations with desirable properties is ongoing.

Many packaging and application assemblies have been developed to enable satisfactory and comfortable application of such fluid products.

In general, an assembly for packaging and applying cosmetics comprises, on the one hand, a body forming a reservoir intended to contain the cosmetic to be applied and, on the other hand, an application surface intended to contact the user ' And an applicator including an applicator member defining the applicator.

As an example of an applicator, the document of French Patent No. 2 872 999 can be mentioned, and the French patent discloses an assembly for packaging and application, particularly comprising an applicator for the lips, referred to as a dip applicator .

The applicator is referred to as a dip applicator when the loading of the cosmetic occurs by immersing or impregnating its application member in the cosmetic.

The fact that the applicator is immersed in the cosmetics allows high loading of the applicator. It is then generally necessary to have a wiping device that allows removal of extra cosmetics in the reservoir. However, it is common to attempt to increase the loading of the applicator by, for example, providing a central orifice.

Other packaging and application assemblies aimed at better controlling the loading of cosmetics on the applicator are also known.

As an example, documents of French Patent No. 2 832 297, French Patent No. 2 814 651 and French Patent No. 2 962 890 can be mentioned in particular.

The document FR 2 832 297 discloses an assembly for packaging and applying cosmetics comprising a reservoir in which a porous applicator element through which the cosmetic passes is mounted. The assembly includes a cap that compresses the application member in the closed position to create a pumping effect of the cosmetic upon opening, the pumping effect facilitating diffusion of the cosmetic product through the application member.

French Patent No. 2 814 651 and French Patent No. 2 962 890 show another way of loading cosmetics into the application member. More specifically, the documents of French Patent No. 2 814 651 and French Patent No. 2 962 990 provide a body forming a reservoir, the body having a housing capable of receiving an application member, the partition of the housing in the reservoir The wall has at least one through-orifice in direct fluid communication with the reservoir. By shaking or reversing the assembly, the cosmetic passes through an opening to impregnate the application member directly on its application surface.

French Patent No. 2 814 651 aims at optimal and relatively large loading of the application member. To do this, the document of French Patent No. 2 814 651 provides a porous application member having an open porosity, wherein a cosmetic dispensing orifice is formed in the opposite side of the non-squeeze application portion when the application member is in place in the housing . The dispense orifices are virtually distributed over the entire application surface.

The document itself of French Patent No. 2 962 890 aims at not overloading the application member. To do this, the document FR 2 962 890 provides a combination of precisely positioned orifices with an application surface formed by a non-cosmetically permeable membrane.

Despite the many types of packaging and application assemblies developed, there is still a need for an assembly that allows for improved application characteristics of certain cosmetics.

Applicants have noted, inter alia, that certain cosmetic formulations still require the development of a specific applicator for its application to the user and for optimization of its makeup result at the user.

The packaging and application assemblies targeted by the present application are very specifically intended for application to lip oil type cosmetics.

More specifically, such compositions intended for make-up and / or care of the lips are in liquid form and comprise, for example, at least 70% by weight of nonvolatile oil, especially silicone oil, and colored or colorless solid particles, Includes pearl polish (nacre).

Formulations intended for the make-up and / or care of the lips have been known for a long time and have been in the form of liquid formulations, such as selectively supported solid compositions in the form of sticks from a gloss, or even pencil- ≪ RTI ID = 0.0 > compositions. ≪ / RTI >

In order to further diversify the composition provided to the consumer, anhydrous or substantially anhydrous formulations have emerged that are much more fluid and contain a higher amount of oil than gloss and are very easy to apply. However, these formulations are only available in versions that are not very colored. Essentially this is due to the fact that it is very difficult to keep a high content of particles suspended in this type of oily medium without losing the charm of such a composition (which is precisely its great fluidity).

In fact, the sedimentation of these particles is observed if there is a large amount of pigment, pearl polish or filler, which leads to the formation of a relatively unattractive cake which may include a lump of particles. The cake thus formed has an additional drawback that it is very coherent. Therefore, it may not be possible to redisperse easily so as to have a homogeneous composition again. As a result, once the particles have settled, the composition becomes substantially unusable and it is no longer possible to obtain homogeneous deposition on the lips, which is not acceptable.

Thus, in order to minimize sedimentation problems, such compositions contain relatively low amounts of solid particles. In this case, however, the number of hues that can be achieved, and also its intensity, is limited. The composition may also contain a dye (and therefore a species that is soluble in the medium in which it is used). However, the number of dyes that can be used in this field is relatively limited, which does not allow much expansion of the range of the proposed color or its intensity, whether the dye is combined with colored solid particles or not.

In addition to the difficulty of the formulation images, this type of cosmetic with sedimentation tendency also presents application difficulties, which does not solve the current packaging and application assembly in an optimal way.

More particularly, in view of the presence of solid particles, the packaging assembly must ensure that the solid particles are resuspended as a homogeneous suspension and ensure good loading of the applicator for easy and accurate application with optimal makeup effect.

In view of this constraint, an assembly of the internal feed type, in which the product must be dispersed through the application member, is not suitable because the dispersion does not occur homogeneously.

Dip applicators are also not optimal because homogeneous reshaping of the particles in cosmetics is difficult. Furthermore, taking into account the high coloring power of the pigmented composition and the high oil content in the composition of the lip oil type, it is advisable to be able to control the loading of the applicator. In the case of excessive loading, it is advantageous for the user to be able to tone down the skin or lips surface with the surface of the applicator that is not loaded or is relatively less loaded.

The apparatus disclosed in the document of French Patent No. 2 814 651 has proven to be unsatisfactory, although permitting relatively easy resuspension by simply manually swinging the bottle.

Although the document FR 2 962 890 mentions compositions which may contain pigments, such assemblies have been found not to provide satisfactory results. One problem, in particular, is that such an applicator unloads the formulation very quickly.

The present invention aims at achieving this purpose in whole or in part, and for this purpose, it has been proposed, on the one hand, to form a body intended to contain the reservoir intended to contain the cosmetic to be applied and, on the other hand, and an applicator including an application member defining a convex application surface having an apex.

The body forming the reservoir includes a housing capable of receiving an application member, the dividing wall of the housing in the reservoir having at least one through-orifice in direct fluid communication with the reservoir. The orifice is located only on at least one end wall of the housing opposite the proximal end of the application member when the application member is in place in the housing of the body forming the reservoir.

The assembly for packaging and application is characterized in that the application member is produced from an open-cell porous material.

The presence of an application member defining a convex application surface with a tip or tip enables precise application of the product in particular.

In particular, an orifice formed in the wall of the housing for receiving the application member enables the cosmetic to be loaded on the application member, in particular during shaking or reversing the reservoir.

The expression " orifice located only in at least one end wall of the housing " is understood to mean that the remainder of the dividing wall is solid, i.e. not punctured.

Thus, surprisingly, Applicants have found that by combining one or more dispensing orifices that are in direct fluid communication with being located in a highly localized manner with a porous application surface, the targeted packaging and application assemblies are particularly suitable for use with solid particles such as pearlescent agents and / To enable accurate, comfortable and homogeneous application of the cosmetics contained in the reservoir.

As is well known, the use of highly localized orifices makes it possible to limit the passage of products through the dividing wall and thus obtain an accurate volume of product without overloading the applicator.

In the context of use with liquid cosmetics, particularly those containing solid particles and in particular with a sedimentation or phase separation tendency, Applicants believe that the presence of a localization orifice opposite the application tip of the application member, Which makes it possible to collect a predetermined amount of formulation which is much more homogeneous than when the orifice is distributed. Thus, even if the orifice is localized to the tip of the applicator as the sifting medium, loading of the homogeneous product to the porous applicator is still obtained.

Without wishing to be bound by any theory, Applicants have found that the use of an application surface made of an open-cell porous material is advantageous in that excessive solvent, especially oil, can be more easily dispersed through the material, Strongly promotes the retention of solid particles. Thus, the difference in migration between the solvent phase and the solid particles appears to provide particularly advantageous makeup properties.

This leads to the concentration of pigment and pearlescent polish type particles around the application tip. This allows precise application, which does not flow and has a large coverage.

The rest of the application surface, especially the peripheral or side area, can be used to tone down the applied product and improve the makeup.

The dispersed solvent phase, in particular the oil, through the porous applicator contributes to the excellent softness of the application over the entire application surface.

Direct fluid communication is understood to mean that the orifice is not combined with any optional-open dispensing means of the type of pump or aerosol that makes it possible for the cosmetic to force the orifice through. Loading of the application member occurs by simply shaking or reversing the reservoir.

This is particularly the case when such a selective-closure mechanism which makes it possible to ensure the leaktightness of the reservoir when the selective-closure mechanism is not used (the product still remains non-mandatory as it passes through the orifice) It does not prevent the use of mechanisms.

According to the present application, the term " near the tip of the application member " is aimed at a tip that extends close to a point-shaped geometric apex. It may be considered that the orifice is located in the region around the geometric apex which represents at most 5% or even 10% of the total surface of the application surface.

Firstly, the orifice is located at the end wall of the housing, which corresponds to the absolute apex of the application member, and is preferably located only at said end wall.

According to the variant of the first embodiment, the wall of the housing has a single orifice.

According to a variant of the second embodiment, the wall of the housing has a plurality of orifices.

The presence of a plurality of orifices makes it possible to retain a relatively small size of orifice so that after homogeneous movement, for example only a few times, homogeneous as possible as possible, ensuring a sufficient passage area for good loading of the application member Making it possible to ensure the passage of a certain quantity of product. In addition, the size of the orifice is also determined as a function of the size of the solid particles to prevent or limit clogging.

In the case of some orifices, the last one is preferentially distributed uniformly around the center of the end wall. This makes it possible to ensure optimal loading of the application tip.

In an advantageously complementary manner, the wall of the housing has a central orifice located at the center of the end wall. The central portion of the end wall is understood to mean the point opposite the geometric apex of the applicator.

According to one preferred embodiment, all or part of the orifices have a substantially circular cross-section. Such a circular cross-section is well suited to avoid clogging. Where appropriate, different cross sections may be conceived depending on the particles used.

In an advantageously complementary manner, the reservoir comprises at least one mixing element, in particular at least one mixing bead. The properties of the blending element, such as weight or size, will be selected as a function of the settling properties of the cosmetic.

Primarily, the application member has an application surface that is at least partially flocked, preferably entirely flocked. In addition to the excellent softness of application, flock fibers also aid in retention of the particles and improve their dispersion.

Advantageously, the applicator is configured to be fastened to the container when not in use, and the application member is received within the housing. The applicator thus makes it possible to close the reservoir.

First of all, the application surface does not have a surface, in particular a recess, which can form a space with the wall of the housing when the application member is housed in the housing. In particular, the application surface does not have a recess on the opposite side of the orifice. Indeed, the presence of the recess can result in the formation of a cavity between the dividing wall of the applicator and the housing, in which the product can settle, which is undesirable.

Preferably, the application member has a generally conical shape with a rounded tip or hemispherical tip. Such a shape is particularly suitable for application to the lips.

More preferably, the orifice is closed by the application surface when the applicator is fastened to the container. This makes it possible to avoid any leakage of product through the orifice when the applicator is in the closed position.

In an advantageously complementary manner, the application surface is at least partially deformed relative to the wall of the housing when the applicator is fastened to the container, and the application member is slightly compressed. Thus, as a function of the properties of the cosmetic, it is possible to arrange the application member under slight compression to add a pump effect which makes it possible to promote the dispersion of the product and in particular the adsorption of the solvent phase or oil. This compression also improves the closure of the orifice by the application member.

The present application also relates to an assembly for packaging and application characterized in that the reservoir comprises liquid cosmetic, in particular solid cosmetic, comprising pigment and / or pearlescent agent or even wax.

In particular, the cosmetic comprises a single phase mixture of at least one nonvolatile oil or some nonvolatile oils in an amount of at least 70% by weight with respect to the weight of the composition, the composition comprising at least one polar or nonpolar nonvolatile hydrocarbon- A thickener and at least one nonionic silicone surfactant and at least colored or colorless solid particles.

BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be better understood by reading the following detailed description in conjunction with the accompanying drawings,

1 is a schematic view of a longitudinal section of an assembly for packaging and application according to the invention,

Figure 2 is a schematic view of the longitudinal section of the application member in the assembly from Figure 1,

Figure 3 is a schematic view of the longitudinal section of the ring forming the housing for the application member from Figure 2,

4 is a schematic plan view of the ring from Fig. 3; Fig.

Figure 1 shows an assembly 1 for packaging and applying liquid cosmetics (P).

The assembly 1 comprises a body 2 forming a reservoir 3 comprising a cosmetic product P to be applied and an application member 5 defining a convex application surface 50 having at least one pointed portion 51, (4).

The body (2) has a free upper edge (21) which defines the opening (22) of the reservoir (3). More specifically, the opening 22 is located at the free upper end of the neck 24 of the body 2.

The body 2 has rotational symmetry. The opening 22 has a circular cross-section. Obviously, other shapes can be conceived.

The body 2 has a housing 7 at an opening 22 capable of receiving the application member 5 and the housing 7 is at least partly divided by the dividing wall 8 in the reservoir 3 The range is fixed.

According to the present application, the dividing wall 8 has at least one through-orifice 9 in direct fluid communication with the reservoir 3.

The dividing wall 8 can be added on the reservoir 3 as illustrated or can be manufactured from a single part by molding with the body of the reservoir.

In this case, the dividing wall 8 is supported by the ring 60 and placed on the opening 22. [

The ring 60 can be mounted on the body 2 by any means, in particular by clip-fastening or adhesive bonding. This may or may not be removable.

In this case, the ring 60 can engage with the neck 24.

To do this, the ring 60 includes an outer peripheral wall 61 and an inner peripheral wall 62, which together define a mounting skirt.

The mounting skirt also provides leakage protection for the product.

Alternatively, a ring as shown in Figure 10J of the document of French Patent No. 2,962,890 may also be conceived.

The applicator 4 includes a top gripping portion 41 on which the application member 5 is mounted.

The gripping portion 41 forms a cap and is capable of closing the reservoir 3 in a leakproof manner by engaging in a removable manner with the upper peripheral wall 63 of the ring 60. More specifically, the peripheral wall 63 of the ring 60 has an outer thread 64 that can cooperate with the complementary inner threading 65 of the gripping portion.

When not in use, and when the gripping portion 41 is screwed onto the ring 60, the application member 5 is received in the housing 7 (Fig. 1).

According to the present application, the application member 5 is made from an open-cell porous material, for example a foam.

In particular, the application member 5 is made from a polyurethane foam, especially of the S90 type (DIN 4102-9 standard).

The application member 5 is mounted on the gripping portion 41 by any known means, in particular by fitting, clip-tightening or snap-fastening.

In this case, the application member 5 has a substantially cylindrical foot portion 55 which is introduced into the corresponding shaft 42 of the gripping portion. The end wall 43 of the shaft 42 increases the mounting area. End wall 43 also ensures that translational motion is blocked.

On the opposite side from the foot portion 55, the application member 5 has a head 56 defining the application surface 51. The head 56 has a general conical shape. The head 56 has a free end or rounded tip that forms the tip 51. In this case, the tip 51 is consequently the absolute tip.

The head 56 has a base having a diameter slightly larger than the diameter of the foot portion 55 and thus has a shoulder 57 that can be supported against the edge of the shaft 42. [ This shoulder 57 makes it possible in particular to provide a better holding of the application member.

The housing (7) is shaped to have a substantially complementary shape to the head (56).

As can be seen in Figure 1, when the applicator 4 is fastened to the reservoir 3 and the application member 5 is in place in the housing, the tip 51 is slightly compressed.

It should also be noted that the application surface 51 is flocked. For application of the flock, a relatively stiff glue after drying will be used. Thus, by drying, the glue helps to stiffen the application member 5.

As shown above, the housing 7 communicates with the interior of the reservoir 3 by a perforated dividing wall 8, which is punctured by a permanent opening orifice 9.

According to the present application the orifices 9 are arranged in the vicinity of the tip 51 of the application member 5 when the application member 5 is in place in the housing 7 of the body 2 forming the reservoir 3 And is located only on at least one end wall of the housing on the opposite side.

In this case, the wall 8 comprises three orifices 9. The orifices 9 are regularly distributed close to and around the center of the end of the wall 8. The orifice has a substantially circular cross-section. In this case, the diameter of the orifice is 1.5 mm.

Thus, the total area of the orifice (s) is approximately 5.3 mm ² . Preferably, the total area of the openings is less than 5.5 mm < ^{2 &} gt ;. The total area of each opening is also sufficient to limit or even prevent clogging.

The center of each orifice 9 is located at a distance of 4.5 mm from the center of the end wall corresponding to the tip 51 of the application member. Preferably, the orifice is located less than 5 mm from the center of the end wall.

Advantageously, the application member 5 closes all the orifices of the wall 8 when the applicator 4 is in place on the reservoir 3. This can be useful to prevent an excessive product from escaping into the housing when the applicator closes the housing.

Advantageously, the reservoir 3 comprises at least one mixing element, in particular at least one mixing bead (not shown). While shaking or reversing, the beads enable the homogenization of the product or even the resuscitation of the particles (if appropriate).

According to one embodiment, the reservoir comprises a liquid cosmetic comprising solid particles, in particular a pigment and / or a pearlescent agent.

Preferred cosmetic compositions to be combined

As indicated above, cosmetics (cosmetic compositions) are present in liquid form at ambient temperature (25 ° C) and atmospheric pressure (1.013x10 ⁵ Pa). More particularly, the viscosity of the composition varies between 0.2 Pa.s and 0.8 Pa.s, preferably between 0.3 Pa.s and 0.7 Pa.s. In general, the viscosity measurement is carried out at 25 DEG C using a Rheomat RM180 viscometer with a No. 2 spindle and the measurement is performed by rotating the spindle in the composition for 10 minutes at 200 revolutions per minute (rpm) Stabilization of the viscosity and the rotational speed of the spindle are observed).

Nonvolatile oil

Thus, the composition comprises at least one non-volatile oil or a single-phase mixture of at least 70% by weight relative to the weight of the composition, of at least one non-volatile oil selected from a polar or non-polar hydrocarbon-based oil.

The mixture was filtered through a closed receptacle for 24 hours at ambient temperature (25 캜), homogenization at this temperature and mixing in a Rayneri mixer (550 rpm, 10 min) and ambient temperature (and atmospheric pressure) , And when no phase separation is observed under the naked eye or under a phase contrast microscope, it is referred to as a single phase. Under these conditions, the term stable single phase mixture is used.

More particularly, for purposes of the present invention, the word " oil " refers to a non-aqueous compound which is liquid and water-immiscible at 25 ° C and atmospheric pressure (1.013 x 10 ⁵ Pa). The term " immiscible " means that the same amount of water and oil mixture does not produce a stable solution containing only one phase, after mixing (for example, at 550 rpm for 10 minutes) Is intended to mean " not. &Quot;

The term " nonvolatile oil " is intended to mean an oil having a vapor pressure at 25 [deg.] C and atmospheric pressure of no 0, less than 0.02 mmHg (2.66 Pa), and even better less than 10 ^-3 mmHg (0.13 Pa).

The term " hydrocarbon-based oil " is intended to mean an oil essentially consisting of carbon and hydrogen atoms, optionally oxygen and nitrogen atoms, or even composed thereof, and containing no silicon or fluorine atoms.

For the purposes of the present invention, the term " nonpolar oil " is intended to mean an oil selected from hydrocarbons, i.e. compounds containing only carbon and hydrogen atoms.

- and mixtures thereof.

Polar nonvolatile hydrocarbon oil

Thus, such a polar hydrocarbon-based oil is formed from carbon and hydrogen atoms and contains at least one oxygen or nitrogen atom but no silicon or fluorine atom.

As a result, it comprises at least one group selected from alcohols, esters, ethers, carboxylic acids, amines and / or amide functionalities.

Preferably, the polar non-volatile hydrocarbon-based oil has no heteroatoms, such as nitrogen and phosphorus, in addition to being free of silicon and fluorine.

Thus, in the case of the present invention, polar non-volatile hydrocarbon-based oils contain one or more oxygen atoms as heteroatoms.

In particular, the polar non-volatile hydrocarbon-based oil (s) comprises at least one alcoholic agent (which is an "alcoholic oil") or at least one esteric agent (which is an "esteric oil"). It should be noted that ester oils can be particularly hydroxylated.

For example, preference is given to dry silicas which have been treated to render the surface hydrophobic and whose particle size is more particularly less than 1 [mu] m. In particular it is possible to replace silanol groups with hydrophobic groups, such as in particular the following groups:

Trimethylsiloxyl groups obtained by treating dry silica in the presence of hexamethyldisilazane. This treated silica is known as " silica silylate " according to CTFA (6th ed., 1995). This may for example Degussa as (Degussa) Co. entitled Aerosil (Aerosil) R812 ^® by, and Cabot Cab by (Cabot) four-title of chamber (Cab-O-Sil) TS -530 ® - O Sold as;

A dimethylsilyloxyl or polydimethylsiloxane group obtained by treating dry silica, in particular in the presence of polydimethylsiloxane or dimethyldichlorosilane. The silica thus treated is known as " silica dimethylsilylate " according to CTFA (6th ed., 1995). This is for the name of Aerosil R972 ^® and Aerosil R974 ^® by gusa used for example, and by the Cabot Corporation Cab-the title of chamber TS-720 ^® - O-chamber TS-610 ^®, and Cab-O Sold.

Particularly hydrophobic dry silicas have particle sizes in the range of, for example, 5 to 200 nm.

Silica airgel is a porous material obtained by (by drying) the replacement of the liquid component of silica gel with air.

The hydrophobic silica airgel particles which can be used have a specific surface area (S _M ) per unit mass of from 500 to 1500 m ² / g, preferably from 600 to 1200 m ² / g, and even more preferably from 600 to 800 m ² / g And a size expressed by a volume average diameter (D [0.5]) of 1 to 1500 μm, more preferably 1 to 1000 μm, preferably 1 to 100 μm, particularly 1 to 30 μm, more preferably 5 To 25 [mu] m, more preferably from 5 to 20 [mu] m, and even more preferably from 5 to 15 [mu] m.

The specific surface area per unit mass can be determined according to the method described in " The Journal of the American Chemical Society, vol. Known as the BET method (Brunauer-Emmett-Teller method), which is described in the International Standard ISO 5794/1 (Annex D) And may be determined by a nitrogen absorption method. The BET specific surface area corresponds to the total specific surface area of the particles under consideration.

The size of the silica airgel particles can be measured by static light scattering using a commercial particle size analyzer of the MasterSizer 2000 type from Malvern. The data are processed based on the Mie scattering theory. This exact theory of isotropic particles makes it possible to determine the "effective" particle diameter for non-spherical particles. This theory is particularly disclosed in publications by Van de Hulst, H. C., Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957.

According to an advantageous embodiment, the hydrophobic silica airgel particles which can be used have a specific surface area (S _M ) per unit mass in the range of 600 to 800 m ² / g and a size expressed as volume average diameter (D [0.5]) of 5 To 20 [mu] m, and even more preferably from 5 to 15 [mu] m.

The aerogels used are aerobic gels of hydrophobic silica, preferably silylated silica (INCI name: silica silylate).

"Hydrophobic silica" means that the surface is treated with a silylating agent such as a halogenated silane such as an alkylchlorosilane, a siloxane, especially a dimethylsiloxane such as hexamethyldisiloxane, or a silazane, so that the OH group is replaced by a silyl group Si-Rn, Is intended to mean any silica functionalized with a trimethylsilyl group.

With regard to the preparation of hydrophobic silica aerogel particles whose surface has been modified by silylation, reference may be made to the document of U.S. Patent No. 7,470,725.

Hydrophobic silica airgel particles having a surface modified with a trimethylsilyl group are preferably used.

As hydrophobic silica aerogels that can be used in the present invention, for example, Aerogel VM-2260 (INCI name: Silica Silylate: average size of about 1000 μm, specific surface area per unit mass: 600 to 800 m ² / g); May include airgel (AEROGEL) TLD 201, 201 OGD airgel, airgel (the cache available on the boat) TLD 203, Nova (ENOVA) ^® airgel MT 1100, MT 1200 Nova airgel on.
