As a nail gel 4 a UV-acrylate is used, which cures by UV radiation. The term gel also refers to viscous fluids, liquid fluids and other photocurable materials in this specification. The gel or light-curable material may be an acrylic-based or acrylic-based material or an acrylic adhesive.

The light source 2 is a UV light source with a UV LED 5 ( 4a . 9 ) and serves to cure the UV-radiation-curing nail gel 4 ,

The device 1 or the applicator pen has a housing 6 made of opaque plastic material in which the reservoir 3 for the nail gel 4 is arranged. The device 1 is as a pen 12 executed or includes pins 12 ' ( 8th ) and 50 ( 9 ) and also has an application element 7 for applying or brushing the nail gel 4 on a nail 8th ( 5a . 8th ), which may be a fingernail or a toenail of a person. The application element 7 is as a brush 9 ( 5a . 8th ).

The brush 9 is with the reservoir 3 through an application opening 10 connected. Between the brush 9 and the reservoir 3 is the application opening 10 available. Ie. the opening 10 allowed the gel 4 flows into a brush area and the brush 9 saturated. This applies to both variants ( 5a . 8th ) too.

The light source 2 is in the first variant in the housing 3 integrated. This can be in the case 3 from a brush 9 be inserted into the opposite side. The light source 3 is on the brush 9 opposite end in the housing 3 arranged so that by turning the pen around 12 a UV ray 14 is usable. In the preferred variant, the light source is separate and designed as a second pen, such as 7 illustrated.

As in 2 is illustrated, the housing of the first variant has a pin shape. The device 1 is designed as a job pen. 2 shows the pen 12 with a pen cap 15 made of plastic. This is in both variants ( 1 . 7 ) opaque. In the second preferred variant, two separate housings 51 . 52 available.

On the pen cap 15 is in the first variant, a nail processing element 16 arranged, as well as in the 3a and 3b is shown. The element 16 It is made of a soft plastic or similar material and is essentially cylindrical. The element 16 has a bevelled end face or a working surface 17 so that a formed tip can be used to manipulate or push back the skin at the nail edge, as is common in manicuring. Analogously, this can be transferred to the second preferred variant.

Light in the sense of this description includes not only the visible spectrum, but also non-visible UV radiation (UV light). The LED 5 has both visible and invisible components, with the non-visible spectral components predominating.

The 4a and 4b show the light source 2 according to the first variant with a cylindrical light source housing 18 , The UV or light source 2 has the front side (rear end of the pin) the LED 5 , Furthermore, the light source 2 three button cell batteries connected in series 20 to power the LED 5 on.

A switch for switching the light source on and off 2 is in 4a shown. The light source housing 18 has the rotatable head part 21 that's the LED 5 wearing. The headboard 21 is in a body 22 screwed, so that a first switching contact 23 depending on the direction of rotation D1 ( 4b ) moved back or forth. This movement (arrow R1) becomes a second, fixed switching contact 24 contacted or not contacted and thus a circuit 25 closed or opened. The main body 22 has in the area of the headboard 21 an internal thread 13 that with an external thread of the head part 21 corresponds. As a result, a rotary switch is realized in a simple manner. The circuit 25 Can be created with tracks, cables and / or other conductors. Also, not shown electronics or other components, such as resistors, capacitors for controlling the LED are possible. For example, the electronics could control the LED to generate pulses of light. Alternatively, several LEDs, z. B. two to four or five LEDs, on this side shown or in the shell region of the housing ( 18 ) possible. These features can be at least partially transferred to the preferred variant.

According to this also in 5a . 5b and 8th shown embodiment of the pen 12 is on the case 6 respectively. 6 ' at a the brush 9 opposite end of a metering device 26 present with a rotary element. This has a threaded portion, which is used to generate a pressure in the reservoir 3 Run to the gel 4 from the reservoir 3 through the application opening 10 to the brush 9 to press. From the brush 9 to the reservoir 3 extends a channel 27 , The brush 9 is made with silicone hair.

5a shows that a piston 28 in the rear reservoir area, by turning a rotatable pin section 30 (Arrow D2 in 5b ) to the brush 9 towards (arrow R2) or vice versa can be moved to the gel through the metering device 26 to press. This principle also applies to the second preferred variant.

First, the nail 8th by applying the nail gel 4 with the brush 9 processed, then the applied gel 4 with the light source 2 hardened. This applies to both variants ( 1 . 7 ) too. Before that, the nail 8th prepared for this processing. An in 6 shown processing element 31 , or pad, is with a first, structured page 32 for filing (sanding) the nail and a second pulp side 33 to clean the nail 8th Mistake. Both sides 32 . 33 are with a liquid-tight release film 34 provided, which lies in between. The pulp side 33 is soaked in alcohol. On the website 32 is a deductible protective cover 35 arranged by a tab 36 is removable by hand.

The nail system comprises according to the first variant a set with the pin 12 and the pad or element 31 , A set can consist of several disposable items of pens with different gels (colors, effects) and a reusable UV light source and multiple pads in each pen. Analogously, the element 31 be used for the second variant.

The invention is characterized by a housing 6 in which a reservoir 3 for the nail gel 4 is arranged, and by an application element 7 for applying, especially for brushing, the nail gel 4 on the nail 8th , in particular on a fingernail, wherein between the application element 7 and the reservoir 3 an application opening 10 is available.

7 shows the preferred variant. This device 1 includes a two-piece nail set. The set includes a transfer pin 12 ' in which the nail gel 8th analogous to 5a is housed and a separate light pen or UV pen 50 in flashlight form or in ballpoint pen form. In the pen 50 or in a separate housing is the light source 2 arranged. The light source 2 is not in the housing for the reservoir 3 integrated. It uses a pen set that includes two pens, like 7 illustrated.

As 7 Furthermore, the diameter of the light pen is larger than the diameter of the applicator pen. The diameter of the light pen 50 is a factor between 1.25 to a maximum of 1.45 times larger than the diameter of the applicator pen. The diameter of the applicator pen is z. B. about 14 mm during the diameter of the UV pen 50 20 mm. Both pins are approximately equal length z. B. about 12 cm to 15 cm. Almost the same length means that one pen is no more than 10% longer than the other pen. Each pen is no longer than 18 cm.

As 9 shows, has the UV pen 50 The nail set a pin-shaped housing with a tapered front end 53 and one from a housing opening 55 outstanding serving UV-LED or light source 2 , At an opposite end 54 indicates the UV pen 50 a switch 56 or button for switching the UV LED or light source on and off 2 , The UV pen is operated like a classic ballpoint pen. It is also possible to use several LEDs.

The power of the UV LED or LEDs is between 0.1 W and 2 W, in particular between 0.15 W and 0.5 W. The wavelength is analogous to the first variant.

As the 7 to 9 show on both housings decoration and design elements 57 and / or logos to be printed.

The invention is not limited to this example, so could the pen 12 also reusable, z. B. with a cartridge executed. Also could be a refill bottle with gel 4 with a syringe, similar to ink cartridges, to refill the pen 12 be used. It would also be conceivable that the brush 9 not fixed, but is releasably secured so that a replacement brush would be used. This could z. B. the light source be firmly integrated in the pen. Also, the solid or detachable brush could be replaced by a foam, sponge and the like. The element 31 can also do without the pen 12 be used. The light source 2 can also be designed as a separate part. As a gel and colored plastics can be used.

Features of an embodiment ( 1 ) may be partially compatible with features of the other embodiment ( 7 ) be combined.
