Description

FIELD OF TECHNOLOGY TO WHICH THE INVENTION RELATES

The invention relates to a face mask.

The present invention relates to the cosmetic or dermatological field for delivering a care product to a user's body surface, at least in part, containing the face.

BACKGROUND OF THE INVENTION

The cosmetic field includes various compositions intended in particular to improve the aesthetic appearance of the skin and in particular the face. The face is one of the main targets of cosmetics manufacturers due to the attention of users to this area. The face is an area of the body surface that is special and unique in the sense that it brings together in small volumes very strong physiological variations in cells and therefore changes in the textures, aspects and properties of the skin that define individual zones. These different areas of the face sometimes have different needs. Thus, a cleanser that targets the mid-face T-zone, which includes the forehead, nose, and sides of the nostrils, and possibly the chin, can dry out the cheeks. Conversely, a moisturizer can add shine to the T-zone. The care products needed for these different areas are different.

There are facial skin care kits that prompt the user to apply the composition to one area and then to another area.

However, these kits have been noted to be of low efficiency. Indeed, the user is left alone with the formulations and their application to the treatment area. In addition, the instructions for use are not necessarily followed, either for the amount, or for the areas of application or method of application. In addition, there is often asymmetry in application, which leads to unsatisfactory results for the user.

Therefore, there is a need to develop a less complex solution and provide more satisfaction to the user's needs.

DISCLOSURE OF THE INVENTION

In view of the foregoing, the present invention relates to a mask, preferably cosmetic, intended for facial care, containing a base for direct or indirect application to a body surface, preferably containing, at least in part, the user's face. The base contains the first surface, called the inner surface, made with the possibility of addressing the surface of the body, and the second surface, called the outer surface, located opposite the inner surface. The inner surface of the base contains a plurality of so-called functional areas, made with the possibility of appropriate overlay on the target area of the body surface or opposite it. A plurality of so-called functional areas contain an adhesive matrix configured to hold the mask in contact with the body surface, and an active composition containing an active component, while at least two so-called functional areas among the plurality of functional areas contain a different active composition.

The proposed solution allows targeted care for each area to be treated, completely and simultaneously.

Thus, it is an advantage of the invention to provide a unique facial care product having different functional areas capable of delivering a different and targeted active composition for each target area. With one movement, the user simultaneously treats the target areas with different and suitable care products. The application of the active composition is carried out at the target site, and the amount of the active ingredient is pre-set, which saves the user from uncertainties and incorrect application of products.

The application of the active formulations, and therefore the treatment, is preferably carried out symmetrically, which makes it possible to obtain satisfactory results.

Preferably, the adhesive matrix is filled with an active compound. By this is meant that the adhesive matrix is mixed with the active composition. Thus, a different adhesive matrix containing a different active composition is located on different so-called functional areas on the inner surface of the body, which can be placed facing the surface of the body.

The mask preferably contains through holes, made with the possibility of placing opposite at least the eyes and/or nose and/or mouth. These openings improve the usability of the mask by preventing the wearer's eyes and/or mouth and/or nose from being covered.

According to a preferred embodiment, the mask covers a large part of the face, in particular the forehead, eye contour, temples, cheeks, chin, nose.

In an alternative embodiment, the mask is in the form of a half-mask and covers the forehead and eye contour.

According to one embodiment, the invention relates to a method for manufacturing a mask as described above, comprising a separate step of applying, preferably by screen printing, an adhesive matrix containing the active composition, in each functional area on the inner surface of the support.

The method of manufacture makes it possible to apply different adhesive matrices of each functional area at the same time, without the risk that the adhesive matrix applied to the functional area will be damaged in subsequent application steps. For example, the applied adhesive matrix adheres to the next protective layer, allowing the adhesive matrix to be applied to the next functional area.

In addition, this one-step screen printing process reduces manufacturing time, labor, and therefore manufacturing cost.

According to this variant, the invention also relates to a screen printing device comprising a frame, preferably in the form of a parallelepiped, containing at least two parallel recesses located transversely, each of which faces each other on the inner surface of two opposite sides. The device contains at least one separator configured to interact with at least two recesses to delimit the functional areas of the mask. The spacers are preferably arranged perpendicular to two opposite ribs into which the recesses extend.

Preferably, the device includes a screen located on the frame to determine the shape of the mask and the area of application of the adhesive matrix. The screen preferably defines the active surface of the mask.

Preferably, the galvanic couples are located on the inner surface of the substrate.

According to one embodiment, the invention relates to a method for manufacturing a mask according to any of the preceding claims, characterized in that it includes a separate step of applying, preferably by screen printing, an adhesive matrix filled with the active composition of each active area on the inner surface of the support.

Preferably, the method comprises a step preceding the application step, including the step of forming galvanic pairs, preferably by printing with conductive ink, on the inner surface of the substrate.

According to one embodiment, the invention relates to a device for carrying out the method described above, characterized in that it contains: a screen printing frame containing at least two parallel recesses located respectively on the inner surfaces opposite each other on two opposite sides of the frame, and at least two recesses located transversely to said sides, at least one separator made with the possibility of interaction with at least two recesses, so as to separate the functional areas of the mask.

Preferably, the device comprises at least one scraper having at least one notch and configured to interact with the frame and at least the spacer.

The mask according to the invention comprises a base 1 comprising a first surface, also referred to as an inner surface 2, and a second surface, also referred to as an outer surface 3. The first surface and the second surface are opposed to each other. The inner surface 2 is configured to face the user's skin. Preferably, the inner surface 2 is configured to be in direct or indirect contact with the user's body surface. "Direct contact" means that the inner surface 2 is applied to the surface of the body, while in indirect contact at least one layer or element is placed between the inner surface 2 and the surface of the body. Body surface refers to the skin membrane, i.e. the user's skin. The body surface may be various skin surfaces of the user.

According to the invention, the mask is preferably flexible, in particular the base 1 is a flexible sheet. The flexibility is such that two opposite periphery points can be connected without destroying the base 1. Thus, the mask according to the invention easily adapts in shape to the application area of the body where it is to be applied, in particular to the shapes of the wearer's face, so as to guarantee sufficient surface coverage. contact between the mask and the skin, providing effective care.

The mask according to the invention is intended for face care. The mask may have cosmetic and/or dermatological uses. The mask may be applied to at least part of the face, preferably the entire face. In one embodiment, the mask may also extend beyond the face towards the neck so as to cover it at least partially. In this case, or alternatively, the mask may expand in the direction of the line of the neck, that is, the upper chest.

The mask may have different shapes than the half mask, i.e. be a mask covering the periphery of the eyes, or a mask covering a large area of the human face, as shown in the drawings. This means that the base 1 is in the form of a face mask, preferably with holes 4 so as to open at least the eyes.

Known cosmetic masks are cosmetic compositions that are applied to the skin of the user for a certain period of time to provide care. The formulations are combined with supports such as nonwovens, paper, or plastic film. The use of a support facilitates the application of the cosmetic formulation to the user. In general, the substrate is impregnated with a cosmetic composition and packaged for sale. The functionality of these products depends primarily on the functionality of the cosmetic formulation and, more particularly, on the active ingredients used in the cosmetic formulation. Thus, in the case of known masks, the treatment is the same over the entire surface of the mask, that is, over the entire surface of the skin treated with the cosmetic composition.

A characteristic feature of the invention is that the inner surface 2 of the mask according to the invention comprises an active surface corresponding to the surface of the mask intended to come into contact with the surface of the body. The active surface contains at least two so-called functional areas 6, 7, 8, 13. The so-called functional area is intended to be applied to the target area 16, 17, 18 of the body surface. Each functional area 6, 7, 8, 13 contains a different active composition containing at least one active ingredient. Thus, each functional area allows for specific care of the target area of the respective body surface. The active composition is delivered to the surface of the skin, then through the upper layers of the epidermis by passive migration.

The functional areas 6, 7, 8 may have different shapes adapted to the target areas for which the mask is designed.

The invention makes it possible to treat each area of the face, for example with an anti-wrinkle formula for the forehead and around the mouth, a composition for concealing under the eyes, a composition for radiance and eliminating spots on the cheeks, all at the same time and in one movement.

According to the first variant illustrated in FIG. 1 and 3, the functional areas 6, 7, 8, 13 have shapes complementary to the target areas 16, 17, 18 to be treated. Preferably, the functional regions extend symmetrically on either side of the vertical axis 10 defined by the sagittal plane. The vertical axis 10 passes through the mask from the forehead to the chin.

According to the second variant illustrated in FIG. 2 and 4, functional areas 6, 7, 8, 13 run parallel to each other. The functional areas are in the form of strips, preferably parallel to each other. The strips run across the vertical axis 10 described above.

In this embodiment, the functional areas 6, 7, 8, 13 are either adjacent or located at a distance from each other.

Preferably, each functional area contains an adhesive matrix 5, in particular adapted to hold the mask in contact with the skin.

Preferably, the adhesive matrix 5 has a thickness of 0.5 to 3 mm.

The adhesive matrix 5 is flexible, that is, the adhesive matrix 5 is designed so as not to change the flexibility of the base 1. The matrix is called adhesive, that is, it is designed to hold the mask against the user's skin. Preferably, the mask is held in contact with the skin only by the adhesive matrix 5. The term "adhesive matrix 5" implies that it is configured to temporarily adhere or adhere to the skin to which it is applied. To do this, the adhesive matrix 5 contains at least one adhesive selected from acrylic acid, polyacrylates, polyisobutylene, polyvinylpyrrolidone, silicones. For example, the matrix has a viscosity of 1 to 150 K, preferably 100 K to 150 K, more preferably 125 cPs (centipoise), measured by the C/5 method.

The adhesive matrix 5 covers the entire inner surface 2 of each functional area 6, 7, 8, 13. Preferably, in order to provide better retention, the adhesive matrix 5 is present on the entire active surface of the inner surface 2.

The active composition contains at least one active ingredient for administration to the skin 4 of the user. By active ingredient is meant a substance that has a therapeutic or cosmetic effect on the user.

The mask according to the invention contains at least two different active compositions, respectively located in the functional area of the mask. The mask optionally contains the number of active compounds equal to the number of functional areas.

According to a preferred embodiment, the active composition is mixed with the adhesive matrix. That is, the mask contains at least two different adhesive matrices because it contains different active compounds.

The substrate 1 can be made from various materials such as paper, plastic or water-insoluble polymer, woven materials (eg woven fabric) and non-woven materials (non-woven fabric). The backing may comprise a breathable material, such as, but not limited to, a layer of cotton or synthetic non-woven fabric, such as fabric materials commonly used for bandages and sports headbands. The base 1 is preferably made of polyethylene terephthalate (PET) or polyurethane (PU). Preferably the base 1 is a flexible film.

Preferably the substrate 1 has a thickness of 20 to 125 µm, preferably 80 µm.

The flexibility of the base 1 ensures conformity with the application area of the body where it is to be applied.

Preferably, the base 1 includes through holes 4 for the convenience of the user. The through holes are designed to be placed against the eyes and/or lips or the mouth and/or nose, depending on the shape of the mask. The through holes 4 are holes formed in the base 1 corresponding to the shape of the eyes. For the lips, the hole 4 may be a hole made in the base 1 in the form of a mouth, or only a cut through the base 1 so as to allow the user to open the mouth. For the nose, the hole 4 may be a hole made in the base 1 in the form of a nose, or a cut or a line 12, 14 passing through the base 1 to pass the tip of the nose.

According to the variant illustrated in FIG. 3 and 4, the mask comprises a plurality of discrete galvanic pairs 11, each galvanic pair comprising a first conductive electrode which is an anode and a second conductive electrode which is a cathode. Galvanic pairs 11 are located on the inner surface 2 of the base 1.

Here, the generation of electricity means that free electrons can pass through the masked skin between the first and second conductive electrodes. This flow of free electrons, in addition to having a net effect on skin stimulation, improves the migration of active compounds, and more particularly active compounds to and through the skin.

The first anode metal and the second cathode metal of each galvanic pair are chosen to have a different standard potential.

In use, the skin provides conduction between the anode and cathode, thus allowing microcurrent to flow through the skin. By using zinc as the first metal to form the anode and silver chloride as the second metal to form the cathode, a microcurrent of about 40 mA can be obtained.

Preferably, the first metal is capable of being oxidized upon contact with the skin and thus creates a galvanic couple with the second metal.

Examples of materials that provide galvanic couples include, but are not limited to, zinc-silver oxide, zinc-silver oxide, zinc-silver halide, zinc-silver chloride, zinc-silver bromide, zinc-silver iodide, and zinc-silver fluoride.

Preferably the mask is passive, i.e. does not include or is not connected to an external current source. The current flowing between the electrodes of the galvanic couples 11 is locally generated by itself.

Conductive electrodes may be applied to substrate 1 by any suitable application method known in the art. For example, one or both of the first and second conductive electrodes may be a metal plate, wire, or mesh, or cloth coated with a metal or other material such as a cloth coated with a metal and its oxide, halide, and sulfide.

Alternatively, the first and second conductive electrodes can be deposited on the substrate 1 using chemical or electrochemical deposition, such as autocatalytic chemoplating and electroplating, as is known in the art. The first and second conductive electrodes may also be applied to the substrate 1 by physical deposition, such as screen printing, spraying, screen printing, laser printing, pad printing, needlepoint printing, dipping, vacuum deposition, or other embossing or transfer processes.

According to a preferred embodiment of the invention, conductive electrodes can be formed by forming galvanic materials in inks suitable for the material deposition process, such as screen printing inks for screen printing or laser inkjet printing inks for laser printing, and may contain ingredients such as solvents , binders or plasticizers.

The size of the galvanic pairs 11 used in the mask according to the invention may depend on the particular application. In one embodiment suitable for cosmetic mask use, the galvanic couple generally occupies an area not exceeding about 4 cm ² . In order to be suitable for use on, for example, a human face, the metal elements forming a galvanic couple are not generally square in shape. The shapes may be oval or otherwise to suit the specific areas of the skin to which the mask is to be applied.

In another embodiment, each galvanic pair 11 occupies an area of no more than about 2 cm ² , for example, no more than 1 cm ² . The overall dimensions of each galvanic pair may vary from about 0.01 cm ² to about 10 cm ² .

The galvanic pairs 11 can be arranged differently, provided that they are separated from each other, that is, the individual galvanic pairs are disconnected and do not touch. Galvanic couples can be arranged as desired to increase or decrease the electric current density.

The adhesive matrix 5, preferably containing active compounds, does not cover the first metal of the galvanic pairs, so as to avoid its oxidation before use. Preferably, at least the first metal comes into contact with the skin.

According to the preferred circumference, the periphery of the base 1 contains several cutouts 9 having, for example, the shape of a notch. These cutouts 9 are adapted to partially fold the base 1 to improve the contact of the base 1 with the wearer's skin.

The mask according to the invention may comprise a removable release cover so as to cover the base 1 and in particular the adhesive matrix 5 before the mask is used. The release liner is typically a sheet of polymer or paper or fabric coated with a polymer that has poor adhesion to the adhesive matrix being used, allowing it to be easily removed prior to use without damaging the treatment mask. Examples of polymers commonly used for release coatings are silicones and polyethylenes.

According to an embodiment of the invention, the manufacturing process includes a separate step of applying the adhesive matrix 5 for a plurality of functional areas.

Before the step of applying the adhesive matrix 5, the manufacturing method optionally includes the step of forming galvanic pairs 11. The galvanic pairs 11 are formed on the inner surface 2 of the base 1. The formation of galvanic pairs 11 is preferably carried out by the methods described above. Preferably, the galvanic pairs 11 are formed by printing with conductive inks, in particular by screen printing.

According to the first variant, the adhesive matrix 5 is applied by means of digital printing. According to a second preferred embodiment, the application is carried out by screen printing. This type of application has the advantage of speed and cost.

The step of applying the adhesive matrix 5 by screen printing includes applying to the mask base 11 a screen printing frame 19 having at least one separator 25 designed to separate the functional areas 6, 7, 8, 13 of the mask. The step of applying the adhesive matrix 5 then includes applying, preferably simultaneously, the adhesive matrix 5 mixed with the active composition to each functional area 6, 7, 8, 13. Preferably, a stripping knife 23 having a shape complementary to that of the frame 19 and the dividers 25 , provides the possibility of simultaneous application of adhesive matrices 5 containing active compounds on different functional areas 6, 7, 8, 13 of the mask.

This method of manufacture is particularly effective in that it enables the manufacture of a mask according to the invention, comprising several functional areas 6, 7, 8, 13, in a separate screen printing step. The production time is thus significantly reduced. In addition, the simultaneous application of the adhesive matrix 5 of the different functional areas 6, 7, 8, 13 completely avoids the risk of the adhesive matrix 5 sticking to possible subsequent screens commonly used in screen printing processes.

According to this embodiment of the invention, an apparatus is provided for performing a screen printing process. The device includes a frame 19 screen printing preferably in the form of a parallelepiped. The frame has four parallel and opposite sides two by two. The device includes a screen (not shown) stretched in frame 19. The screen contains free zones and solid zones, like a stencil. The screen preferably has free zones and solid zones to complement the shape of the mask. For example, solid areas correspond to through holes 4 of the mask and/or galvanic couples 11, so that the applied adhesive matrix 5 does not cover these areas. Preferably, the screen defines the active surface of the mask. The frame 19 includes recesses 20 located on the inner surface 22 of two opposite sides 21 of the frame 19 for accommodating separators 25. The recesses 21 are distributed on the inner surfaces 22 facing each other of the two opposite sides 21 of the frame 19. The recesses 20 are parallel to each other and extend transversely to sides 21 on which they are formed. The separators 25 are detachable elements having sufficient rigidity so that they cannot be deformed by the stripping knife 23 and are arranged transversely with respect to the two sides 21 receiving the notches 20 and parallel to each other. Removing knife 23 contains cutouts 24, made with the possibility of interaction with the separators 25. The distance between the recesses 20 corresponds to the distance between two separators 25 or between the separator 25 and one side of the frame 19. The specified distance corresponds to the width of the functional area 6, 7, 8, 13. On fig. 8 illustrates a device element according to this embodiment of the invention.

In FIG. 1 shows a mask according to the first embodiment. The mask is designed to cover most of the wearer's face. The mask has through holes 4, in particular first holes 4a and second holes 4b, so as to enable the wearer to keep his eyes open while using the mask. The base 1 also includes a third opening 4c so as not to cover the wearer's mouth when using the mask. The base 1 further comprises a cutting line 12 which is shaped like the lower part of a person's nose. The cut line 12 allows the base 1 to be placed around the bottom of the user's nose.

The mask contains six functional areas 6, 7, 8, 13:

the functional areas 6a and 6b are intended to overlap with the target area 16 corresponding to the temples. Functional areas 6a and 6b contain the same active composition and are located symmetrically on both sides of the vertical axis 10 running along the sagittal plane.

the functional area 7 is intended to be applied to the target area 17 corresponding to the forehead and under the eyes. Functional area 7 contains two sub-regions 7a, 7b containing the same active composition and located symmetrically on both sides of the vertical axis 10, which runs along the sagittal plane.

- functional areas 8a and 8b are intended to be applied to the target area 18 corresponding to the cheeks, while the functional areas 8a and 8b contain the same active composition and are located symmetrically on both sides of the vertical axis 10 running along the sagittal plane

The functional areas are spaced no more than 5 mm apart, preferably approximately 1 mm, so as to provide proximity to treatments that allow treatment over the entire surface of the skin.

According to this embodiment, the functional areas are formed by digital printing.

In FIG. 2 shows a mask according to the second variant. The mask is designed to cover most of the wearer's face. The mask has a shape similar to that described for FIG. 1. The mask contains through holes 4, in particular, the first hole 4a and the second hole 4b for the eyes, the third hole 4c for the mouth, the hole 4d for the tip of the nose. The base 1 further comprises a slit line 14 which is in the form of a longitudinal portion on either side of the nose so as to allow the base 1 to be placed on the wearer's nose.

The mask contains four functional areas 6, 7, 8, 13:

the functional area 6 is intended to be superimposed on the target area 16 corresponding to the temples and forehead. The functional area 6 extends in a substantially transverse direction, preferably perpendicular to a vertical axis 10 running along the sagittal plane,

- the functional area 7 is intended to be superimposed on the target area 17, the corresponding area under the eye and above the nose. The functional area 7 extends in a substantially transverse direction, preferably perpendicular to a vertical axis 10 running along the sagittal plane,

- the functional area 8 is intended to be superimposed on the target area 18 corresponding to the cheeks. The functional area 8 extends in a substantially transverse direction, preferably perpendicular to a vertical axis 10 running along the sagittal plane,
