Description

Title of the invention: Coating comprising a matrix housing a capsule and device comprising such a coating

[0001] The invention relates to a coating comprising a matrix housing a capsule containing a product. It also relates to a device comprising such a coating. It also relates to an eyeglass element comprising such a coating. It also relates to a pair of eyeglasses comprising at least one such eyeglass element. It also relates to a method for producing such a coating. It also relates to a method for releasing the product.

[0002] In many everyday situations, it is desirable to be able to release a product, such as a treatment product or a scented product, at a given moment. The treatment product is, for example, a product intended to keep insects away and the scented product is, for example, a fragrance intended to enhance a situation or the well-being of the user.

[0003] To avoid wasting the product, it is desirable to be able to release the product very quickly, very simply, and at the right time.

[0004] Vaporizers are known which are capable of diffusing a product by a user pressing a button which releases a quantity of product contained in a reserve. Such a system is complex, heavy and bulky. In addition, such a system can be difficult to use for very young or even very old users. Furthermore, such a system is not always available within reach of the user, which can delay and ultimately spoil its use at the appropriate time.

[0005] There is therefore a need today to have an alternative which allows a product to be released very quickly, very simply and at the right time.

[0006] Thus, an aim of the present invention is to propose a coating which makes it possible to release a product very quickly, in a few seconds in particular, very simply and at the right time.

[0007] Considering the above, a problem which the present invention proposes to solve consists in particular in allowing users to have a coating making it possible to release a product very quickly, very simply and at the right time.

[0008] The solution to this problem posed has as its first object a coating comprising a matrix housing at least one capsule, characterized in that the capsule contains at least one of an odorous product and / or a treatment product.

[0009] Another subject of the invention is a device and in particular a spectacle element which constitutes a pair of spectacles and which comprises a coating according to the invention.

[0010] Another subject of the invention is a pair of glasses comprising at least one eyeglass element according to the invention.

[0011] Another subject of the invention is a method for producing a coating according to the invention, characterized in that the method comprises any one of an injection, extrusion and / or rotational molding phase.

[0012] Another subject of the invention is a method for producing a coating according to the invention, characterized in that the method comprises any one of a screen printing, flexography, spraying and / or pad printing phase.

[0013] Its additional subject is a method for diffusing any of an odorous product and / or a treatment product, characterized in that the diffusion method comprises a step of rubbing the coating according to the invention.

[0014] Thus, a coating of the present invention is a coating comprising a matrix which houses at least one capsule.

[0015] According to the present invention, the capsule contains at least one of an odorous product and / or a treatment product.

[0016] It is understood that the encapsulation of the odorous product and / or the treatment product in a matrix constitutes a simple packaging of the odorous product and / or the treatment product which facilitates its release, and therefore its use by a user very quickly, in a few seconds in particular, very simply, and at the right time.

[0017] The coating comprises a capsule shaped into a sphere with a diameter which is, for example, less than 50 microns. Such a capsule is easy to produce and delimits a suitable volume, in particular necessary and sufficient, to produce the effect desired by the user. The capsule is preferably made of a material impermeable to oxygen. This results in preservation of the treatment product and / or the odorous product against oxidation of any of the latter, which guarantees the durability of such a coating for possible use over a long period.

[0018] Said capsule contains at least one odorous product and / or at least one treatment product. The encapsulation of the product makes it possible to provide various coatings comprising either capsules comprising a single odorous product, or capsules comprising a single treatment product, or capsules comprising a mixture of an odorous product and a treatment product, or capsules comprising a mixture of several odorous products, or capsules comprising a mixture of several treatment products, or capsules comprising a mixture of several odorous products and several treatment products, or capsules comprising an odorous product and treatment products, or capsules comprising odorous products and a treatment product.

[0019] Preferably, the odorous product is chosen from a fragrance, an aroma and / or an essential oil, taken alone or in a mixture. We note the significant diversity that can present such a coating.

[0020] Preferably, the treatment product is a product chosen from products intended to keep insects away, such as lice, mosquitoes, mites taken alone or in a mixture. We also note the significant diversity that such a coating can present.

[0021] Advantageously, the matrix is ​​a polymer whose melting temperature is lower than 220°C, and which is compatible with the temperature resistance of the fragrance. Such a melting temperature chosen for the polymer matrix is ​​the best compromise between a wide diversity of matrix and ease of shaping the matrix.

[0022] The matrix is ​​preferably chosen from polyethylene, polypropylene, cellulose acetate, acrylonitrile butadiene styrene, ethyl vinyl acetate, polyoxymethylene, polypropylene, polystyrene, polyamide, polyvinyl chloride and polyurethane. The polymer matrix can also be of plant origin, bio compostable, recyclable and of bio sourced origin, and can comprise corn starch, algae, castor oil with a mineral or plant filler.

[0023] According to an alternative embodiment of the invention, the matrix is ​​an ink. According to such an alternative embodiment, the matrix is ​​capable of covering a large number of supports, paper, plastic or the like.

[0024] According to another alternative embodiment of the invention, the matrix is ​​a varnish capable of covering any support. It is understood that the diffusion of said products is accentuated in a varnish, the varnish being applied superficially to a support, such that the diffusion is improved for superficial capsules compared to capsules present in the mass of a coating.

[0025] It is noted that the varnish is for example applied to glasses, in particular by spraying.

[0026] According to a first advantageous embodiment of the invention, the capsule is shaped into a sphere with a diameter which is for example less than 50 microns, said capsule being made of a material impermeable to oxygen and contains at least one odorous product and at least one treatment product.

[0027] According to a second advantageous embodiment of the invention, the coating according to the invention comprises: - an odoriferous product which is a fragrance, an aroma and / or an essential oil, taken alone or in a mixture; and / or - a treatment product which is a product intended to keep insects (lice, mosquitoes, mites, etc.) away, taken alone or in a mixture.

[0028] The present invention also relates to a spectacle element comprising such a coating. The spectacle element is indifferently a spectacle branch, a nose glasses, or any portion thereof. According to such an alternative embodiment, the coating of the present invention is easily and quickly within reach of the user who wears glasses comprising at least one such eyeglass element. This results in constant, rapid availability, without any particular effort for the user.

[0029] The present invention also relates to a pair of glasses comprising at least one such eyeglass element.

[0030] The present invention also relates to a method for producing such a coating, the method comprising any one of an injection, extrusion and / or rotational molding phase.

[0031] The present invention also relates to a method for producing such a coating, the method comprising any one of a screen printing, flexography, spraying, immersion in a bath and / or pad printing phase.

[0032] The present invention also relates to a method for diffusing any of an odorous product and / or a treatment product, the diffusion method comprising a step of rubbing such a coating, in particular by means of a finger or another part of the user's body.

[0033] It is noted that such diffusion does not destroy or alter any of the odorous product and / or the treatment product, but that a release of said products is obtained by porosity of the capsules without having to break the latter.

[0034] The invention and the advantages resulting therefrom will be better understood upon reading the description and the non-limiting embodiments which follow, with regard to the appended figures in which:

[0035] [Fig-1] represents a sectional view of a coating of the present invention.

[0036] [Fig.2] represents a side view of a branch of glasses comprising a re garment illustrated in [Fig.l].

[0037] [Fig.3] represents in perspective a pair of glasses comprising a branch of glasses illustrated in [Fig.2].

[0038] [Fig.4] schematically represents a process of diffusion of a constituent product of a coating illustrated in [Fig.l].

[0039] In [Fig.l], a section of a coating 1 of the present invention is shown. The coating 1 comprises a matrix 2 which houses capsules 3. In other words, the capsules 3 are distributed inside the matrix 2 in a random manner, some of these capsules 3 being flush with a surface 4 of the matrix 2. This surface 4 is preferably a free surface accessible to a user. The capsules 3 are for example shaped into a sphere with a diameter D which is between 5 microns and 50 microns, and for example of the order of 10 microns, to within + / - 10%.

[0040] Each capsule 3 contains at least one of an odorous product 5a and / or a treatment product 5b. According to various variants, the capsules 3 comprise a single odorous product 5a, or the capsules 3 comprise a single treatment product 5b, or the capsules 3 comprise a mixture of an odorous product 5a and a treatment product 5b, or the capsules 3 comprise a mixture of several odorous products 5a, or the capsules 3 comprise a mixture of several treatment products 5b, or the capsules 3 comprise a mixture of several odorous products 5a and several treatment products 5b, or the capsules 3 comprise an odorous product 5a and treatment products 5b, or the capsules 3 comprise odorous products 5a and a treatment product 5b, or any combination of the variants mentioned above. In other words, the matrix 2 is capable of containing any combination of the capsules 3 listed above.

[0041] Each capsule 3 is made of a material impermeable to oxygen, to protect the odorous product 5a and / or the treatment product 5b from oxidation which would impair the qualities of one or other of the products 5a, 5b.

[0042] The odorous product 5a is for example a fragrance, an aroma, an essential oil or the like, taken alone or in a mixture.

[0043] The treatment product 5b is, for example, a product intended to keep away insects, in particular lice, mosquitoes, and / or mites, taken alone or in a mixture.

[0044] Preferably, the matrix 2 is a polymer whose melting temperature is lower than 220°C, to facilitate its implementation using manufacturing processes explained below.

[0045] For example, matrix 2 is chosen from polyethylene, polypropylene, cellulose acetate, acrylonitrile butadiene styrene, ethyl vinyl acetate, polyoxymethylene, polypropylene, polystyrene, polyamide, polyvinyl chloride and polyurethane. The polymer matrix can also be of plant origin, bio-compostable, recyclable and of bio-sourced origin, such as corn starch, algae, castor oil.

[0046] According to a preferred embodiment, the matrix 2 is an ink. It is thus capable of being applied to any support, such as paper, glass, a plastic material, a metallic material, a natural material, such as wood, or another similar material. In this case, the coating 1 is for example deposited on the paper by a production method comprising either a screen printing phase, or a flexography phase, or a spraying phase and / or a pad printing phase.

[0047] According to another embodiment illustrated in [Fig. 2], the coating 1 at least partially covers a spectacle branch 10. The spectacle branch 10 extending between a hinge 11 and a sleeve 12, the coating 1 covers an overlapping zone 13 which is comprised between the hinge 11 and the sleeve 12, and which is capable of covering the sleeve 12, on all of its faces. Preferably, such an overlapping zone 13 equips an external face 14 of the spectacle branch 10. It is understood that the external face 14 of the spectacle branch 10 is the face opposite an internal face 15 of the spectacle branch which is placed opposite the user's head when the user wears his spectacles.

[0048] According to yet another embodiment, the spectacle arm 10 is obtained by a production method comprising an injection phase, an extrusion phase, a rotational molding phase or the like. In this case, the matrix 2 of the coating 1 is the material mainly constituting the spectacle arm 10 itself.

[0049] In [Fig. 3], a pair of glasses 20 is illustrated comprising at least one such glasses branch 10 and preferably two such glasses branches 10. The pair of glasses 20 comprises a frame 21 carrying two lenses 22, for example connected by a bridge 23, a nose 24 being interposed between the two lenses 22 to serve as a support for the pair of glasses 20 on the user.

[0050] It is noted that the coating 1 is capable of equipping any element of glasses 10' constituting the pair of glasses 20, such as the glasses branch 10, the bridge 23, the nose 24 or any other portion of the pair of glasses 20.

[0051] In [Fig. 4], a method for diffusing the odorous product 5a and / or the treatment product 5b is illustrated which comprises a step of rubbing a finger 30 of the user against the surface 4 of the coating 1, in particular from a movement 31 parallel to the surface 4 which exerts a pressure 32 on the surface 4 of the matrix 2. Such a pressure 32 causes heating and / or expansion of the capsules 3, which releases the odorous product 5a and / or the treatment product 5b and allows its rapid and instantaneous diffusion into the environment.

[0052] These arrangements are such that it is easy to diffuse the odorous product 5a and / or the treatment product 5b into the atmosphere by simply rubbing the user on a branch of glasses 10, or another element of glasses 10', which is easily accessible for a finger 30 or another part of the user's body. Such diffusion may, for example, be related to the user's vision, for example when attending a show, such as a cinema session or the like.

[0053] These arrangements are also such that it is easy to exert pressure 32 on a postcard or pages of a magazine comprising such a coating 1 to release a fragrance related to an illustration carried by the postcard. It is noted that this pressure 32 can be exerted by the simple fact of wearing the pair of glasses 20 in the case where the coating 1 covers the sleeves 12 of the pair of glasses 20 which naturally rest on the user's ears.

[0054] It is noted that the diffusion can be naturally light, under the effect of heat in particular, then accentuated by the pressure 32 exerted voluntarily by the user.

[0055] In both cases, an olfactory function is obtained from the pair of glasses 20 or from the postcard or other medium that is fully controlled by the user.
