The present invention relates to a device for applying a substance to an area of the body.
The present invention relates to a device for the application of a substance in a liquid or semi-liquid state, or of a fluid or semi-fluid mixture, or of a substance in gel or cream, on any area of the body.
Preferably, the present invention relates to a device for applying polish to nails, preferably semi-permanent UV enamel. The invention can therefore be inserted in the technical sector of production of devices and accessories for applying enamel on nails, normally for ornamental purposes.
Preferably, the present invention relates to a device for applying a cosmetic substance to an area of the skin (of the body or face), for example in correspondence of the mouth or eyes, but also of the hair or nails. Preferably, the present invention relates to a device for the application of a cosmetic substance used for skin care (also called “skin-care”) or for decorative cosmetics (also called “make-up”), such as primer face, eye primer, lip primer, eyelash primer, foundation or concealer, moisturizer and/or dye, makeup, eyeshadow, mascara/rimmel, blush, lipstick or similar substances. The invention can therefore be inserted in the technical sector of production of devices and accessories for the application of cosmetic substances, in particular in the “skin-care” or “make-up” sector.
Preferably, the present invention relates to a device for applying a medicinal substance to an area of the body, for example for applying a medicinal substance in order to treat a skin wound. The invention can therefore be inserted in the technical sector of production of devices and accessories for the application of medicinal substances.
Conveniently, the substances applicable by means of the device according to the invention can have various consistencies and viscosities, as well as various compositions.
As is known, since ancient times, women have used to decorate their nails, applying enamels of the most varied colors. It is also known that normal enamels (known in the technical jargon of the sector with the term “enamel”) have the drawback of having a short duration.
More clearly, the enamel applied to the nails tends to fade or peel after a few washes, forcing the user to apply it again after a short period of time.
In order to obtain enamels with greater persistence, the so-called semi-permanent gel enamels have been developed (known in the technical jargon of the sector with the term “enamel”), whose duration on the nails can reach up to three weeks. This lengthening of the duration of the enamel is obtained thanks to the use of particular enamels that polymerize (ie solidify) when exposed to the action of UV rays.
Currently, the enamel and the semi-permanent enamel are housed in liquid form inside a tank, for example a bottle or a bottle. The application of the semi-permanent UV gel enamels takes place through small brushes that are normally equipped with the bottles, usually used for the marketing of enamels.
The use of brushes to apply enamel on the nails currently on the market presents a series of critical issues, such as inaccuracy of the brush strokes, color smears, especially when their use is not carried out by cosmetics professionals.
In particular, the use of brushes involves a considerable waste of time; and in fact, the average time for the application of the enamel on all the nails of the hands is not less than 40 minutes.
Furthermore, the use of a brush for applying enamel, when used in a professional center, can lead to contamination between one client and another, of yeast infections, fungi or molds or bacteria.
In order to obviate the aforementioned drawbacks of the known art, a bottle containing the aforementioned enamel equipped with an applicator device provided at one end thereof is known in the technical sector, obviating the need to extract the aforementioned brush from the bottle.
However, also the applicator device of the known type has proved to be not free from drawbacks in practice.
The main drawback resides in the fact that the known type applicator device provides a hole made at one end of the bottle for the release of the enamel to be applied on the nail. This hole is made in such a way as to always remain open, placing the enamel contained in the bottle constantly in contact with the air of the external environment.
This constant contact with the external environment places the enamel at risk of contamination with external agents, which could affect the goodness of the enamel, impoverishing its qualities and leading to its preventive disposal.
The same problems also exist substantially for the application of substances in the context of decorative cosmetics (also called “make-up”) or skin care (also called “skin-care”).
In particular, in the professional field of decorative cosmetics (or skin care, the specialized person (for example the make-up artist or the beautician) generally uses the same applicator device in an indiscriminate way to apply the cosmetic substance (for example an eye primer or an eye contour) on several subjects, with the risk of transmitting any infections or contaminations of one subject to others. Furthermore, even in the consumer and non-professional context, the substance that escapes from the known applicator devices without being then applied to the area body, undesirably remains in contact with the air with the risk of contamination.
Currently, in addition, in the context of skin care, depending on the area of the body to be treated, different applicator devices are used, even if the substance to be applied is the EP0630597 describes a device for dispensing and applying a fluid product, comprising a bottle containing the product, a bristle holder equipped with a ring of bristles which is fixed around an impregnation channel configured to impregnate the bristles with the product to be dispensed/applied, and a needle holder equipped with a needle. The bristle holder is movable in translation with respect to the needle holder between a position in which the needle closes the impregnation channel and a position in which the impregnation channel is open. The device also comprises a sleeve which is manually operated in rotation with respect to the bottle so as to cause longitudinal displacement of the bristle-holder. Furthermore, the sleeve is configured in such a way that, in the closed position by the impregnation channel, the bristles are contained entirely inside the sleeve.
WO91/12992 discloses a portable dispensing device for highly volatile fluids, of the pump type and with hydraulic drive. The device comprises an elongated structure in which an opening for discharging the fluid towards the outside is defined and which is provided with bristles at one of its ends; moreover, mobile means are provided between a closed position in which they prevent the passage of the fluid through said discharge opening towards the outside and an open position in which they allow the passage of the fluid through said discharge opening.

Basically, advantageously, it is possible to easily and quickly change the bristle body 80 according to the receiving user.
Furthermore, the bristles 18 are made of the aforementioned polymeric material suitable for being sanitized before and/or during their use.
Moreover, advantageously, it is possible to easily and quickly change the bristle body 80 so as to use the one having the bristles 18 most suitable according to the application. For example, in the enamel sector, the use of a bristle body 80 with fewer bristles may be required (see
Preferably, the device 1 comprises at least one cap 21 which is removable and which is configured to cover the bristles 18.
Advantageously, the cap 21 is configured so as to cover the bristles 18 and the locking element 19 and is preferably provided with a lower edge capable of abutting against a shoulder of the gripping portion 9 of the valve body 7.
The device 1 described up to now can be applied to tanks 100 of a known type, or, advantageously, it can be made mechanically linked to a tank 100 thereof shaped and sized for the connection of the aforementioned device, without thereby departing from the scope of protection of this patent.
The present invention also relates to an apparatus for applying a substance to an area of the body, for example for applying enamel, in particular UV semi-permanent polish, comprising
In particular, the apparatus comprises a device 1 with at least one dispensing body 2 mechanically connected to said tank 100 and equipped with at least one outlet mouth 5, placed in communication with said outlet opening 101 of said tank 100, for dispensing of said enamel or other substance.
Conveniently, the apparatus further comprises valve means 6 mechanically associated with said dispensing body 2 and movable between a closed configuration, in which they obstruct said at least one outlet mouth 5 to fluidically separate said enamel or other substance from an external environment, and an open configuration, in which they free said at least one outlet mouth 5, to allow said enamel or other substance to escape from said tank 100 through said at least one outlet mouth 5.
Furthermore, the apparatus according to the invention comprises a bristle body 80 with a plurality of bristles 18 and mechanically removably associated with said valve means 6 so that the bristles 18 intercept said enamel, or other substance to be applied, at the outlet from said at least one outlet mouth 5, to distribute it thus on at least one fingernail or other body area of a receiving user.
All the characteristics described above with reference to the device 1 and/or the tank 100 and with reference to any part thereof are to be understood as described also with reference to the aforementioned apparatus.
The device is particularly advantageous as:
Unlike EP0630597 and WO91/12992, in the device according to the invention the bristle body is mechanically associated with the valve means in a removable way; on the contrary, in EP0630597 the bristles are integrated and fixed inside the tip of the bristle-holder body which is longitudinally movable and, a removal/replacement of the bristles necessarily requires the complete replacement or modification of the entire dispensing device. The fact that in the device according to the invention the bristle body is associated in a mechanically removable way with the valve means is particularly advantageous since it makes the device highly hygienic, allowing in particular the rapid and easy replacement of the bristle body, i.e. the body provided with the bristles, which are the only parts of the device that come into direct contact with the recipient user's body area and which, as such, are highly and easily contaminated. Furthermore, the fact that in the device according to the invention the bristle body is associated in a mechanically removable way with the valve means is particularly advantageous since it makes the device particularly versatile in its use, allowing in particular the rapid and easy replacement of the bristle body in order to be able to use the most suitable bristles according to the type of application and/or the area of the body to be treated. Furthermore, unlike WO91/12992, in the device according to the invention the bristle body is mounted on the valve means which are movable between a closed configuration and an open configuration.
The present invention has been illustrated and described in some of its preferred embodiments, but it is understood that executive variations may apply thereto in practice, without however departing from the scope of protection of the present patent for industrial invention.
