Abstract

The pen is used to apply gel polish and includes a brush (5) for applying it to a fingernail, as well as a battery-operated or rechargeable battery-operated LED-LEV lamp (11) for UV light to cure the gel polish applied with the brush (5). The housing of the pen contains a nail polish or gel polish bottle in the form of a replacement cartridge or replacement bottle (23), which is equipped with an open threaded connecting piece (33) at the top for closing with a threaded cap (2) and a closed threaded stub (34) on the side of the cartridge base. The threaded stub (34) on the side of the base of the replacement cartridge or replacement bottle (23) can be screwed into a mating thread on the sleeve (18) on the housing of the pen. After unscrewing the threaded cap (2), the brush (5) can be used to apply the polish to a fingernail. The replacement cartridge or replacement bottle (23) can be quickly and easily replaced in the pen to change the desired gel polish colour.

Description

Pen with exchangeable cartridge or bottle for a nail polish, a brush for application and an LED for curing the nail polish

[0001] The invention relates to a pen or pencil which can be easily carried in a handbag or jacket pocket and which allows nail polish to be applied quickly and safely to a fingernail and then hardened using UV light. In a special embodiment, the pen can contain an RFID or NFC chip, i.e. a transponder chip, so that it can be placed on a fingernail using nail gel or self-adhesive and covered with gel so that it is held in place by the nail polish, either visibly in the case of clear varnish or invisibly with top coat. The chip can thus be concealed under or on top of the nail polish or a nail treatment system (gel varnish, acrylic, wrap or the like). In this way, an RFID chip can be elegantly attached to a natural or artificial fingernail or toenail. Ordinary nail polish lasts for about 2 to 3 days after application, then it becomes brittle and can chip. Gel nail polish, on the other hand, needs to be applied far less often. After application, for example using a brush, the gel nail polish is hardened with a special light source that emits UV light. A fingernail coated in this way stays beautiful for around 2 weeks, and sometimes longer if it is not subjected to much wear and tear, and the polish lasts over this period without affecting its quality or aesthetic appearance. When traveling, hardening is often a problem because you don't have a suitable UV light source to hand.

REVISED SHEET (RULE 91) ISA/EP [0002] Such a pen is known from EP 3 869 996. It is a pen with a sealable cavity for holding gel varnish and with a brush for applying it to a fingernail, as well as a battery-operated LED LEV lamp for UV light for hardening GEL varnish applied with the brush on a fingernail. This pen contains another sealable cavity that contains one or more RFID chips for removing and placing on a fingernail as required and attaching it to it using gel varnish. Its external shape can be designed similarly to a ballpoint pen or ink fountain pen, with a cavity in a tube-like pen body for holding the gel varnish and a brush for applying it to a fingernail. A cap can be screwed or clipped onto the pen body as a handle for the brush that protrudes into the gel polish container on this handle, and at the front end of the pen body there is a screw-on sleeve with an LED/LEV light with battery/rechargeable battery for hardening the applied gel polish using UV light. In one variant, the pen can also have a compartment for a nail file, which can be clipped together with a pen body or a threaded cap to form a handle for the nail file. The disadvantage of this pen is that the sealable cavity has to be filled with gel polish by hand. The gel polish is supplied in bottles as standard, and it is a laborious procedure to drip the gel polish from the bottle into the cavity. This can result in gel polish being spilled, after which the pen and the surface, such as a table top, have to be laboriously cleaned. In addition, the pen can only be used with the previously filled gel polish. A quick change to a different gel polish color is not possible. If the color of the gel polish is to be changed, the cavity must be emptied, cleaned and refilled with gel polish of a different color, which is laborious and time-consuming.

[0003] The object of the present invention is therefore to improve such a pen and to make its handling more practical and simpler, so that it is easier to refill, can be used quickly with interchangeable gel varnishes of different desired colors, and the associated UV light can be switched on and off with one hand.

REVISED SHEET (RULE 91) ISA/EP [0004] This object is achieved by a pen for applying varnish, which includes a threaded cap with a brush for applying the gel varnish to a fingernail, as well as a battery-operated LED LEV lamp for UV light for hardening the varnish applied with the brush on a fingernail, and which is characterized in that it contains a varnish exchange cartridge or bottle, which has an open threaded connector with a threaded cap and brush at the top, and the base of which runs into a closed threaded stub, a plug nipple or a plug nipple with lateral cams, for connecting the varnish exchange cartridge or bottle to the sleeve on the housing of the pen by screwing or inserting it into this sleeve or additionally securing it in the manner of a bayonet lock with its cams therein, and in which sleeve of the housing the LED (UV) lamp and its power supply are accommodated.

[0005] This pen offers users the advantage that the bottles can be easily exchanged as needed in order to use the gel polish color they want. The pen can be carried securely on the body anywhere and for all activities, and the RFID chip can be removed or replaced at any time.

[0006] The figures show first a conventional pen with an internal cartridge and then a pen according to this invention. The advantages and the structure as well as the function of the pen are described and explained below.

[0007] This conventional pen shown here is designed from the outside similar to a writing pen, of a similar thickness and length as shown in Figure 1. This means that it can be taken anywhere in a jacket pocket or handbag and is therefore always ready to hand. This pen contains several cavities and consists of a pen body 1 and a cover cap 2 that can be attached or screwed onto it. At the front end of the pen 1, a light 11 based on a light emitting diode (LED) or a levitating lamp (LEV) 11 is installed, i.e. an LED or LEV light 11 that is enclosed and protected by an inner cone 13 that opens outwards. A clip 16, preferably made of metal, enables the pen to be secured when it is carried in an inside jacket pocket, for example. This clip 16 can also be porous or have a rough surface so that it is suitable for filing a natural or artificial nail. In addition, the pen can be designed in a special way to serve as a container for one or more chips, as will be shown below.

[0008] In Figure 2, this pin is shown in a side view. Opposite the clip 16, in the front area, a switch 12 can be seen for switching the LED or LEV light 11 on and off, which is visible in Figure 1. A threaded cap 3 is screwed onto the cover cap 2.

[0009] Figure 3 shows this pen in a longitudinal section and thus provides a view of its interior. The pen body 1 has a cavity 7 in the form of a blind hole, which is accessible when the cover cap 2 is unscrewed or removed. It is partially filled with a varnish 14 in the form of a special nail varnish, which hardens under UV light. In order to use it, this cavity 7 must first be filled with varnish 14, which is cumbersome and impractical. There is also always the danger of spilling varnish or spilling it on the pen and the surface, such as a table top, which then have to be laboriously cleaned. At the lower end of the cover cap 2, a A brush 5 extends out of the cover cap and this brush 5 can be inserted into the blind hole, i.e. into the cavity 7 in the pen body 1, where it dips into the paint 14 contained therein. The cover cap 2 can be screwed to the pen body 1 to form a seal, for which purpose an external thread 6 is provided on the pen body 1, onto which the internal thread at the lower end of the cover cap 2 can be screwed. Instead of a threaded connection, a plug connection with a snap-in engagement can be used.

[0010] The brush 5 itself consists of a plastic handle with flat bristles 17 at the end, which are suitable for applying a liquid varnish 14 to a fingernail. In an optional embodiment, the pen body 1 can be designed in such a way that it forms a flat compartment next to the blind hole 7 for the varnish 14, similar to a knife sheath, into which a nail file with or without a handle can be inserted. The cover cap 2 can then form a handle for this nail file, for easier work on a fingernail. At the lower end of the pen body 1, it has another blind hole that is open at the bottom and is designed as a battery compartment for accommodating a battery 15 or a rechargeable battery. The pen body 1 can also be equipped with a photovoltaic element for continuously charging the battery as soon as sufficient light hits this element. In addition, the pen body 1 can be equipped with a USB socket accessible from the outside for plugging in a charging cable. At the lower end of the pen body 1, this forms a step and a taper, which is provided with an external thread 10. A sleeve 18 with its matching internal thread can be screwed onto this external thread 10, enclosing and making electrical contact with the battery 15, for example a button battery for an LED or LEV light 1 1 at the other end of the sleeve 18, which sits there in an inner cone 13, which runs outwards towards the lower edge of the sleeve 18. An on-off switch 12 is installed on the side of the pen body 1 to switch the light 1 1 on and off.

[001 1 ] In the example shown, there is a cylindrical cavity 22 in the form of a blind hole inside the cover cap 2. Several RFID chips 21 can be inserted into this cavity 22 and stored therein. The cavity 22 is the cover cap 2 can be closed by means of a threaded cap 3. The cover cap 2 can be equipped with a clip 16 as in a fountain pen.

[0012] Each of these RFID chips 21 can interact with an RFID or NFC system if it is held close enough to a transmitter/receiver of an RFID or NFC system. This RFID chip 21 acts as a transponder, colloquially also called a radio tag, and it can be located on an object or in a living being and contain an identifying code. The RFID or NFC system includes a reader for reading the identifier of a detected RFID chip 21. RFID transponders can be as small as a grain of rice and can be implanted, for example in pets or people. In addition, it is possible to produce RFID or NFC transponders using a special printing process for stable circuits made of polymers. The advantages of this technology arise from the combination of the small size, the unobtrusive reading option and the low price of the transponders, sometimes in the euro cent range. The coupling is achieved by alternating magnetic fields generated by the reader within a short range or by high-frequency radio waves. This not only transmits data, but also supplies the transponder with energy. To achieve greater ranges, active transponders with their own power supply are used, but these are associated with higher costs. The reader contains software in the form of a microprogram that controls the actual reading process and an RFID middleware with interfaces to other IT systems and databases. By identifying the RFID chip 21 on a person, a connection to a software application can be established, which enables a wide range of applications.

[0013] This pen, filled with varnish and equipped with several RFID chips 21, makes it possible to mount such a chip 21 on a natural or artificial fingernail at any time and anywhere. To do this, the fingernail is prepared as far as necessary with the nail file. Then the desired RFID chip 21 is removed from the blind hole 22 after unscrewing the threaded cap 3 and the threaded cap 3 is screwed back on to secure the remaining RFID chips 21 contained. The removal can also be done by pressing out the individual RFID or NFC chips 21. Then the cover cap 2 is unscrewed or pulled off the pen body 1. Now the varnish 14 can be applied to the fingernail using the brush 5, taking it out of the blind hole 7 in the pen body 1. The removed RFID chip 21 can be placed directly on the natural or artificial nail, as this may already be provided with adhesive. Or this chip can be placed on the applied varnish or lacquer layer on the fingernail and then painted over with varnish so that it is completely enclosed by the varnish or lacquer. Several layers of varnish 14 can be applied until the RFID chip 21 is completely covered by varnish. Then the cover cap 2 is screwed or plugged back onto the pen body 1 and then the switch 12 is set to ON so that the LED or LEV light 11 is switched on. The emitted UV light is directed at the varnish 14 on the fingernail, which ensures that it hardens in a few seconds. After the varnish 14 has hardened, the RFID chip 21 is secured and invisibly - or, if desired, visibly, by simply applying a thin coating - on the fingernail, embedded in a layer of nail varnish or varnish 14.

[0014] In this way, different RFID chips 21 can be attached to the different fingernails of one hand. One can be used, for example, to trigger a financial transaction through the NFC identification of the person paying, who simply has to hold their fingernail with the relevant RFID chip 21 near a transmitter/reader set up for this purpose. Another fingernail with a different RFID chip 21 can be used, for example, to unlock and lock a car door, another for operating the lock on the apartment door, etc. One chip can also offer the possibility of triggering several applications.

[0015] Figure 4 shows an embodiment of the pen with a two-part pen body 1, an upper 4 and lower pen body 9. In this embodiment, the paint can be contained in a cartridge 19 that fits into the cavity 7 in the lower pen body 9. This cartridge 19 can be equipped with a brush with flat bristles 20, which brush protrudes from it and to whose bristles a channel leads so that the brush bristles 20 are supplied with paint directly from the cartridge due to a capillary effect or by squeezing the cartridge together. Compared to the designs according to Figures 1 to 3, the brush is contained in the pen rotated by 180° and after removing the cover cap 2 the brush can be guided directly with the pen. The paint cartridge 19 is housed in the lower pen body 9 and is connected to the pen body 9. Together with the upper pen body 4, in which the cartridge is also held there, a rotating mechanism can be implemented. The two parts 4, 9 of the pen body can then be rotated against each other, whereby a cartridge 19 made of rubber-elastic material can be rotated. The resulting reduction in the filling volume of the cartridge 19 feeds the paint into the brush bristles 20. A flat compartment similar to a knife sheath can be provided in the pen body 1, into which a nail file can be inserted, the cover cap 2 then forming the handle of this nail file. In this case, the cover cap 2 is held on the pen body 1 by purely axially plugging it in using a snap-in mechanism, instead of being screwed onto it. In another variant, the nail file can also be designed at its rear end in such a way that it can be plugged together with the cover cap 2 after removal, so that the cover cap 2 serves as the handle of the nail file, or in a similar way the nail file can be plugged together with the pen body 1, so that the pen body 1 serves as the handle.

[0016] Figure 5 now shows a pen according to the invention with a screw-on gel varnish cartridge or bottle 23. At its lower end or the cartridge base, in the figure on the right-hand side of the varnish cartridge or bottle 23, it forms a threaded attachment or threaded stub that is closed at the bottom, or forms a closed plug nipple there, or optionally a closed plug nipple with side cams for the realization of a bayonet lock, which is not visible in Figure 5. At its front end there is an open threaded connector onto which a cover cap 2 is screwed, from which a brush 5 is formed coaxially downwards or here to the right, but not visible here. In a first embodiment, the varnish cartridge or bottle 23 therefore has a thread on both ends. To the right in the figure, after the exchangeable cartridge or bottle 23, there is a sleeve 18 as a housing for the battery or accumulator, and at the lower, here At the right end there is a rubber-elastic cap 24 with an LED light 1 1 embedded in the center of the front surface 25. This cap 24 can be made entirely of hard rubber or of metal, e.g. aluminum, and then coated on the outside with a rubber-elastic material. This allows the pin to be pressed onto a surface with the front surface 25 of this cap 24 and when it is then simultaneously rotated about its longitudinal axis, the cap 24 remains stationary due to the static friction with the surface and only the pin with the sleeve 18, the exchangeable cartridge 23 and the cover cap 2 rotates. This relative movement between the pin and the cap 24 can be used to conveniently switch the LED (UV) light 1 1 on and off with one hand, as will be described in more detail below.

[0017] Figure 6 shows the rear or lower part of this pin according to the invention with the rubber-elastic cap 24 for one-handed switching of the circuit board 26 and thus switching the LED (UV) lamp 11 on and off, as well as with the battery 15 inserted in the sleeve 18 in a longitudinal section. The negative pole 27 is located at the back of the battery 15, and the positive pole 28 is at the front. The positive pole end of the battery 15 is seated here in a form-fitting holder 29, into which this battery end fits exactly with its positive pole 28. The electrically conductive sleeve 18 acts as a conductor. A steel spring (not shown here) acts on the negative pole 27 of the battery 15 and is connected to the electrically conductive sleeve 18, which then leads electrically to the circuit board 26, while the positive pole 28 of the battery 15 is connected directly to the circuit board 26 and is electrically connected to it. Therefore, no wiring is necessary, which represents a great simplification in terms of production technology. The cap 24, which is coated with elastic rubber or is made of hard rubber, is placed on the lower end of the sleeve 18 and has an inwardly projecting bead 30 which fits into a circumferential groove 31 on the outside of the sleeve 18 and holds the cap 24 on the sleeve 18, but allows it to rotate relative to the sleeve 18.

[0018] Figure 7 shows a first variant of the gel varnish replacement cartridge 23 that can be used in this pen according to the invention, with a special feature of threads 33, 34 on both sides. The upper threaded connector 33 is open, the lower threaded stub is closed. These replacement cartridges 23 can be made of glass or plastic. The upper, open threaded connector 33 is closed with a cover cap 2, and the lower, closed threaded stub 34 forms a thread stub, so to speak. Suitable threads include external threads M13 with a diameter of 13 mm, while the exchangeable cartridge or bottle 23 is designed as a cylindrical tube with a diameter of 16 mm and a length of 45 mm, for example, and then offers a volume of approx. 5 ml when the brush is dipped in it, which is usually enough to paint 30 to 50 fingernails. The thread of the lower threaded stub 34 is advantageously designed in the opposite direction to that of the open threaded connector 33. By turning it to the left, the exchangeable cartridge 23 can then be screwed into the sleeve 18 on the pin and is held therein. Unscrewing the cover cap 2 can then, in the best case, tighten the screw connection to the pin even further. After using the brush 5 with the cover cap 2, the latter is screwed back onto the threaded connector 33 and not tightened too tightly so that the screw connection of the replacement cartridge or bottle 23 in the pen does not come loose.

[0019] In a first alternative, as shown in Figure 8, the lower threaded stub is replaced by a closed plug nipple 38. This plug nipple 38 can then be inserted into the sleeve 18 with a precise fit, just as a lid can be inserted into most lipsticks. In a further, second alternative, the lower threaded stub is replaced by a plug nipple 39 with lateral cams 32, as shown in Figure 9. This plug nipple 39 can then be inserted with its lateral cams 32 into a slot inside the sleeve 18 and then meets a compression spring at the bottom. It can then be rotated, causing its cams 32 to move into the slotted slots branching off to the side and finally move into slotted pockets leading slightly upwards and are held in this position by the force of the compression spring. This creates a classic bayonet lock, which is also easy to use and holds the paint cartridge or bottle 23 securely in the sleeve 18.

[0020] Next, Figure 10 shows the pen according to the invention in a longitudinal section, with a cover cap 2 and a brush 5 projecting coaxially on its inside with flat bristles 17 at the end. The paint exchange cartridge or

REVISED SHEET (RULE 91) ISA/EP -bottle 23 is screwed into the sleeve 18 with its lower closed threaded stub 34, preferably with a left-hand thread. This means that it is screwed into the sleeve 18 with a counterclockwise rotation, which has a corresponding internal thread. Alternatively, the paint exchange cartridge 23 can also just be inserted axially and held in the sleeve by pure adhesion, or it can be inserted axially by means of a bayonet lock and secured by a compression spring after a slight rotation in the sleeve 18. Between the lower end of the threaded stub 34 and the inserted battery 15, there is space for an insert container 35, which can be used to hold one or more RFID chips 21.

[0021 ] In practice, the user inserts the gel varnish replacement bottle or the gel varnish replacement cartridge or bottle 23 into the pen by screwing or inserting it, and the pen is then ready to be carried around and to apply the gel varnish contained in the cartridge 23 with its specific color at any time. If a different gel varnish color is to be applied, the user can very easily and quickly replace the replacement cartridge or bottle 23 with a replacement bottle or replacement cartridge or bottle 23 with the desired varnish color.

[0022] For use, the pen is held with one hand in an upright position with the threaded cap 2 at the top and then with the other hand the threaded cap 2 is unscrewed from the exchange cartridge and the brush 5 is pulled out of the gel varnish 14 and the varnish is applied to a fingernail or toenail. During application, the pen can be placed on a table with the lower rubber cap 24 with its flat front side 25 so that the hand with the fingernails to be painted remains free. When the varnish has been applied to all the fingernails of one hand, this hand is laid flat on the table, for example. Now the varnish must be hardened using UV light. With the free hand, the pen can be rotated by pressing its rubber cap 24 onto the table surface, whereby the rubber cap 24 resting on it remains stationary. The relative movement generated with one hand switches on the LED (UV) lamp 11 and the light can be directed at the individual fingernails with the same hand until the varnish has hardened. Then the same procedure follows for the Fingernails of the other hand.

[0023] This pen with its threaded cap 2, its exchangeable cartridge or bottle 23 and its sleeve 18 can be cylindrical as shown in the figures. Alternatively, however, it can also be designed in the cross-section in the shape of a prism or a polygon.

[0024] Figure 11 shows the inserted circuit board 26 with the push button switch 36 with the rubber cap 24 running around the outside in a cross section, with the LED (UV) lamp 11 switched off. The spring-loaded push button switch 36 is here extended radially from the circuit board 26 with its electronic components and protrudes into an inner recess 37 in the rubber cap 24. If the rubber cap 24 is rotated relative to the sleeve 18 and the exchange cartridge 23 screwed onto it, here clockwise, the wedge 30 moves onto the push button 36 and pushes it against the spring force against the circuit board 26 and switches the electrical contact. This state is shown in Figure 12. The recess 37 in the inside of the rubber cap 24 is now empty and the wedge 30 has moved onto the push button switch 36 and presses it permanently against the circuit board 26.

[0025] With this pen, filled with gel varnish, the gel varnish can be applied anywhere, even on the go, to a natural or artificial fingernail. To do this, the fingernail is prepared with the nail file as necessary. Then, with the brush 5, varnish 14 is taken from the exchangeable cartridge 23 in the pen body 1 and applied to the fingernail so that it is completely covered by the gel varnish or as desired. Several layers of varnish 14 can be applied. The cover cap 2 is then screwed back onto the open threaded connector 33 of the exchangeable cartridge 23 inserted into the pen and then the LED or LEV light 11 is switched on and UV light is emitted. The emitted UV light is directed at the varnish 14 on the fingernail, which ensures that it hardens in a few seconds. The gel varnish can thus be immediately hardened on the spot. In this way, you can draw on the different fingernails of one hand using the other hand and this pen. Apply to fingernails and cure.
