Description

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

[0001] The invention relates to a pen or pencil which is easy to carry in a handbag or jacket pocket and which allows nail polish to be applied quickly and safely to a fingernail and then cured using UV light. In a special embodiment, the pen can contain an RFID or NFC chip, i.e. a transponder chip, so that this can be attached to a fingernail using nail gel or self-adhesively and covered with gel so that it is held in place by the nail polish, either visibly in the case of clear polish 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 polish, acrylic, wrap or the like). In this way, an RFID chip can be elegantly attached to a natural or artificial fingernail or toenail. Conventional nail polish lasts for approx.2 to 3 days, then it becomes brittle and can chip. Gel nail polish, on the other hand, needs to be applied far less frequently. After application, for example, with a brush, the gel nail polish is cured with a special light source that emits UV light. A fingernail coated in this way will stay beautiful for about 2 weeks, and with light use, sometimes longer, and the polish will last throughout this period without compromising its quality or aesthetic appearance. Curing is often a problem when traveling, as a suitable UV light source isn't readily available. 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 polish and a brush for applying it to a fingernail, as well as a battery-operated LED LEV lamp for UV light for curing gel polish applied to a fingernail with the brush. This pen contains a further sealable cavity containing one or more RFID chips for removal as needed and placement on a fingernail and attachment thereto using gel polish. Its external shape can be designed similarly to a ballpoint pen or fountain pen, with a cavity in a tubular pen body for holding the gel polish and a brush for applying it to a fingernail.A cap can be screwed or clipped onto the pen body to form a handle for the brush that extends into the gel polish container. At the front end of the pen body is a screw-on sleeve containing an LED / LEV light with a battery for curing the applied gel polish using UV light. In one variant, the pen can also have a compartment for a nail file. Once removed, the compartment can be clipped onto the pen body or a threaded cap to form a handle for the nail file. The disadvantage of this pen is that the sealable cavity must be filled with gel polish by hand. The gel polish is usually supplied in bottles, and it is a laborious process to drip the gel polish from the bottle into the cavity. This can result in gel polish spilling, requiring the pen and any surface, such as a tabletop, to be laboriously cleaned.Furthermore, the pen can only be used with the previously filled gel polish. Quickly changing to a different gel polish color is not possible. If the color of the gel polish needs to be changed, the cavity must be emptied, cleaned, and refilled with a different color of gel polish, 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 various desired colors, and that the associated UV light can be switched on and off with one hand. REVISED SHEET (RULE 91) ISA / EP

[0004] This task is solved 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 curing 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 nozzle at the top with a threaded cap and brush, and whose base ends in a closed threaded stub, a plug-in nipple or a plug-in nipple with lateral cams, for connecting the varnish exchange cartridge or bottle to the sleeve on the housing of the pen, by screwing or plugging it into this sleeve or additionally being secured with its cams in the manner of a bayonet lock, and in which sleeve of the housing the LED (UV) lamp and its power supply are accommodated.

[0005] This pen offers users the advantage of easily swapping bottles as needed to apply the desired gel polish color. The pen can be securely carried on the body anywhere and for all activities, yet the RFID chip can be removed or replaced at any time.

[0006] The figures first show a conventional pen with an internal cartridge, followed by a pen according to this invention. The advantages, structure, and function of the pen are described and explained below. It shows: Figure 1 : The conventional pen in a perspective view; Figure 2: The conventional pen in a side view, Figure 3: The conventional pen shown in a longitudinal section; Figure 4: A conventional pen with a two-part pen body with Rotatable paint cartridge and container for one or more RFID chips; Figure 5: A pen according to the invention with insertable paint exchange Cartridge; Figure 6: The front part of the pen according to the invention with a rubber-elastic cap for one-handed switching of the circuit board and thus switching on and off the LED (UV) lamp, as well as the battery inserted in the housing, shown in a longitudinal section; Figure 7: A pin insertable into the housing of the inventive pen Paint replacement cartridge with an open threaded connector at the top and a closed threaded stub at the bottom; Figure 8: A housing of the pen according to the invention that can be inserted Paint exchange cartridge with an open threaded connector at the top and a closed plug nipple at the bottom; Figure 9: A pin insertable into the housing of the inventive pen Paint exchange cartridge with an open threaded connector at the top and a closed plug nipple with side cams at the bottom; Figure 10: The pen shown in a longitudinal section, with lid cap and Brush, with inserted replacement cartridge with threads on both sides, as well as the inserted battery and the rubber-elastic cap for one-handed switching the LED (UV) light on and off; Figure 1 1 : The circuit board with the push button switch with the Rubber cap shown in a cross-section, in the off state; Figure 12: The circuit board with the push button switch with the Rubber cap shown in a cross-section, twisted towards the circuit board and thus in the switched-on state.

[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 and carried in a jacket pocket or handbag and is therefore always at hand. This pen contains several cavities and consists of a pen body 1 and a cap 2 that can be plugged or screwed onto it. At the front end of the pen 1 there is built-in a light 11 based on a light emitting diode (LED) or a levitating lamp (LEV), i.e. an LED or LEV light 11 that is enclosed and protected by an outwardly opening inner cone 13. A clip 16, preferably made of metal, enables the pen to be secured when it is carried, for example, in the inside pocket of a jacket.This clip 16 can also be porous or have a rough surface, making it suitable for filing natural or artificial nails. Furthermore, in a special design, the pen can serve as a container for one or more chips, as will be shown below.

[0008] Figure 2 shows a side view of this pen. Opposite the clip 16, in the front area, you can see a switch 12 for turning the LED or LEV light 11, visible in Figure 1, on and off. 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 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 irradiation. Therefore, before using it, one must first fill this cavity 7 with varnish 14, which is cumbersome and impractical. There is also always the danger of varnish spilling or dripping onto the pen and the surface, such as a table top, which then have to be laboriously cleaned. At the lower end of the cap 2, an axially extending A brush 5 extends from 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 is immersed in the lacquer 14 contained therein. The cover cap 2 can be screwed sealingly to the pen body 1. For this 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-in 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 ends, which are suitable for applying a liquid varnish 14 to a fingernail. In an optional embodiment, the pen body 1 can be designed such that, next to the blind hole 7 for the varnish 14, it forms a flat compartment, similar to a knife sheath, into which a nail file with or without a handle can be inserted. The lid 2 can then form a handle for this nail file, making it easier to work on a fingernail. At the lower end of the pen body 1, it has another, downwardly open blind hole, which serves as a battery compartment for 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 pin body 1 can be equipped with an externally accessible USB socket for plugging in a charging cable. At the lower end of the pin body 1, this forms a step and a taper 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 11 at the other end of the sleeve 18, which is seated there in an inner cone 13 that tapers outwards towards the lower edge of the sleeve 18. An on-off switch 12 is installed on the side of the pin body 1 to switch the light 11 on and off.

[0011] In the example shown, a cylindrical cavity 22 in the form of a blind hole is located inside the lid cap 2. Several RFID chips 21 can be inserted and stored in this cavity 22. The cavity 22 is The lid cap 2 can be closed by means of a threaded cap 3. The lid 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 can be attached to an object or in a living being and contain an identifying code. The RFID or NFC system includes a reader for reading the ID 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 humans. Furthermore, 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 readability, and the low price of the transponders, sometimes in the euro cent range.Coupling occurs via short-range alternating magnetic fields generated by the reader or via high-frequency radio waves. This not only transmits data but also supplies the transponder with power. 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 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, enabling a wide range of applications.

[0013] This pen, filled with varnish and equipped with several RFID chips 21, allows such a chip 21 to be mounted on a natural or artificial fingernail anytime and anywhere. To do this, the fingernail is prepared as necessary with a 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. Removal can also be achieved by pressing out the individual RFID or NFC chips 21. Then the lid 2 is unscrewed or removed from the pen body 1. Now, using the brush 5, varnish 14 can be applied to the fingernail by removing it from 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 layer of varnish or lacquer 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. The lid 2 is then screwed or plugged back onto the pen body 1 and the switch 12 is set to ON so that the LED or LEV light 11 is switched on.The emitted UV light is directed onto the nail polish 14 on the fingernail, ensuring its curing in a few seconds. After the polish 14 has cured, the RFID chip 21 is securely and invisibly affixed to the fingernail—or, if desired, visibly, by simply applying a thin coating—embedded in a layer of nail polish or polish 14.

[0014] In this way, different RFID chips 21 can be attached to each fingernail on a hand. One can, for example, be used to initiate a financial transaction through the NFC identification of the payer, who simply needs to hold their fingernail with the corresponding RFID chip 21 near a transmitter / reader set up for this purpose. Another fingernail with a different RFID chip 21 can, for example, be used to unlock and lock a car door, another to operate the apartment door lock, etc. One chip can also offer the possibility of triggering multiple 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, which 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 capillary action or by squeezing the cartridge together. Compared to the designs according to Figures 1 to 3, the brush is rotated by 180° in the pen and after removing the cap 2 the brush can be guided directly with the pen. The paint cartridge 19 is housed in the lower pen body 9 and connected to the pen body 9. Together with the upper pen body 4, in which the cartridge is also held, a rotating mechanism can be realized. 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, with the lid cap 2 then forming the handle of this nail file. In this case, the lid cap 2 is held on the pen body 1 by purely axial insertion 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 such that, after removal, it can be plugged together with the lid cap 2, so that the lid 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 shows a pen according to the invention with a screw-on gel polish cartridge or bottle 23. At its lower end or the cartridge base, in the figure on the right-hand side of the polish cartridge or bottle 23, it forms a threaded attachment or threaded stub that is closed at the bottom, or forms a closed plug-in nipple there, or optionally a closed plug-in nipple with lateral cams for the realization of a bayonet closure, which is not visible in Figure 5. At its front end there is an open threaded connector, onto which a lid cap 2 is screwed, from which a brush 5 is formed coaxially downwards or, in this case, to the right, but not visible here. In a first embodiment, the polish 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 bottom, here. At the right end is a rubber-elastic cap 24 with an LED light 11 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 if 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 exchange cartridge 23 and the cover cap 2 rotates. This relative movement between the pin and cap 24 can be used to conveniently switch the LED (UV) light 11 on and off with one hand, as will be described in more detail below.

[0017] Figure 6 shows a longitudinal section of the rear or lower part of this inventive pin 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. The negative pole 27 is located at the rear of the battery 15, and the positive pole 28 is located at the front. The positive pole end of the battery 15 sits in a form-fitting socket 29, into which this battery end fits precisely with its positive pole 28. The electrically conductive sleeve 18 acts as a conductor. A steel spring (not shown here) acts on the negative terminal 27 of the battery 15 and is connected to the electrically conductive sleeve 18, which then leads electrically to the circuit board 26. The positive terminal 28 of the battery 15 connects directly to the circuit board 26 and is electrically connected to it. Therefore, no wiring is required, which represents a significant simplification in production.The cap 24, which is coated with a rubber elastic material 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 firmly on the sleeve 18 but allows its rotation relative to the sleeve 18.

[0018] Figure 7 shows a first variant of the gel polish 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 connection 33 is open, the lower threaded stub is closed. These 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. A suitable thread is, for example, an M13 external thread with a diameter of 13 mm, while the exchangeable cartridge or bottle 23 is designed as a cylindrical tube, for example, 16 mm in diameter and 45 mm in length, and then offers a content volume of approximately 5 ml when the brush is immersed, which is generally sufficient for painting 30 to 50 fingernails. Advantageously, the thread of the lower threaded stub 34 is designed to run 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 there. Unscrewing the cover cap 2 can then, in the best case, further tighten the screw connection to the pin.After using the brush 5 with the lid cap 2, this 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-in nipple 38. This plug-in nipple 38 can then be precisely inserted into the sleeve 18, just as a lid can be inserted into most lipsticks. In a further, second alternative, the lower threaded stub is replaced by a plug-in nipple 39 with lateral cams 32, as shown in Figure 9. This plug-in nipple 39 can then be pushed 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 laterally branching slots and finally into slotted pockets that lead 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 exchange 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 lid cap 2 and on its inside coaxially projecting brush 5 with flat bristles 17 at the end. The paint exchange cartridge or REVISED SHEET (RULE 91) ISA / EP The paint 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 be simply inserted axially and held in the sleeve purely by adhesion, or inserted axially by means of a bayonet lock and, after a slight rotation in the sleeve 18, secured by a compression spring. Between the lower end of the threaded stub 34 and the inserted battery 15, there is space for an insert container 35, which can serve to accommodate one or more RFID chips 21.

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

[0022] To use, the pen is held upright with one hand with the threaded cap 2 on top. Then, with the other hand, the threaded cap 2 is unscrewed from the exchangeable cartridge, the brush 5 is pulled out of the gel polish 14, and the polish is applied to a fingernail or toenail. During application, the pen can be placed on a table with the lower rubber cap 24 and its flat front side 25 so that the hand with the fingernails to be painted remains free. Once the polish has been applied to all the fingernails on one hand, for example, this hand is laid flat on the table. The polish now needs to be cured 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 remains stationary.The relative movement generated with one hand turns on the LED (UV) lamp 11, and the light can be directed onto the individual fingernails with the same hand until the polish is cured. The same procedure then 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, it can also be designed in the shape of a prism or polygon in cross-section.

[0024] Figure 11 shows the inserted circuit board 26 with the push-button switch 36 and the rubber cap 24 surrounding it, shown in a cross-section, with the LED (UV) lamp 11 switched off. The spring-loaded push-button switch 36 is extended radially from the circuit board 26 with its electronic components and projects into an inner recess 37 in the rubber cap 24. If the rubber cap 24 is rotated relative to the sleeve 18 and the replaceable cartridge 23 screwed onto it, here clockwise, the wedge 30 moves onto the push-button 36 and pushes it against the acting spring force against the circuit board 26, thus switching 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 is permanently pressing it against the circuit board 26.

[0025] With this pen, filled with gel polish, the gel polish can be applied anywhere, even on the go, to natural or artificial fingernails. To do this, the fingernail is prepared with a nail file as necessary. Then, using the brush 5, polish 14 is taken from the exchangeable cartridge 23 in the pen body 1 and applied to the fingernail so that it is completely covered with gel polish or as desired. Several layers of polish 14 can be applied. The lid 2 is then screwed back onto the open threaded connector 33 of the exchangeable cartridge 23 inserted into the pen, and the LED or LEV light 11 is switched on, emitting UV light. The emitted UV light is directed onto the polish 14 on the fingernail, ensuring it hardens in just a few seconds. The gel polish can thus be hardened instantly 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.
