Description

Device for applying a liquid medium

Field of the invention

The invention relates to a device for applying a liquid or powdery medium having a flexible width in the application element and at least one lateral limiting element for the exact and simplified application of this liquid or powdery medium. The invention further relates to a kit containing this device and a vessel which comprises the liquid medium and a wiper member for stripping the liquid or powdery medium from the delimiting element and / or applicator element. The invention also relates to a method for applying a liquid or powdery medium using the device according to the invention.

Background of the invention

Numerous devices for applying a liquid medium, in particular from the field of cosmetic products, are known from the prior art. The liquid medium is currently mainly applied with applicators such as brushes or Abrolleinrichtungen, but can also be done via a spray device. The known from the prior art devices are usually used in conjunction with a vessel containing the medium to be applied.

Just the clean painting of fingernails or toenails is a challenge dar. Nails represent curved surfaces that are variable in their contour. Optimal nail polish application should result in a smooth surface without grooves, blisters, pores, eyes or runners. In addition, the coating should be uniformly thick and covering the entire surface. The biggest difficulty, however, is to paint the entire nail surface, without the nail polish is applied to the adjacent nail fold or the cuticle. This is complicated by the rapid curing of the nail polish, which leaves the user very little time to process the paint. Since a first application cures very quickly on the surface, overcoating often leads to irregularities in the paint surface.

Because of the circumstances explained above, it is therefore very difficult to produce a cleanly contoured and smooth paint surface with conventional nail polish brushes. Inexperienced users are therefore very likely to grapple when painting the nails, i. Also co-lacquer the adjacent nail bed or even the toe or finger skin or paint only a partial area of the nails, or even create a dirty surface. This explains why a large proportion of women (according to a survey carried out in 2016 in Düsseldorf, this is 55%) despite a positive attitude to painted nails rarely or not at all the fingernails paint.

Therefore, first automated devices for improved nail polish application have also been developed. For a cleanly contoured application of paint, stencils or adhesive tapes are used for delimitation. This procedure is cumbersome and error-prone and often requires aftertreatment (eg, by cleaning the stencil or removing paint residues that "creep" under the stencil or tape).

Alternatively, the nail bed can be coated with silicone compounds or oils that repel the varnish. This means a further process step, in which an unclean application of these compounds to the nail bed immediately entails an unclean nail bag application. In addition, the products used are often substances that are harmful to the organism or the environment.

German Offenlegungsschrift DE 3708984 A1 relates to a brush, in particular for nail polish, on whose holder at least two stems (2, 3) with two bristle bundles (4, 5) are provided (see FIG. 1). This is a broader paint job possible and it can also be several colors of nail polish in one Apply step adjacent. However, even this brush has the disadvantage that the nail polish can easily get to the adjacent nail fold.

European patent application EP 1 836 921 A1 relates to a nail varnishing device with a rolling roller. The roller may have different surfaces. This is intended to be a controlled, i. more uniform paint can be achieved. This assumes, however, that the previous stripping of the roller also takes place in just as controlled manner. Especially a roller has the disadvantage that the inking laterally "frayed" and thus does not give a clear limit and also gives a cylindrical roller with curved surfaces no uniform order.

DE 199 60 51 1 A1 relates to a device and a method for the automatic application of nail varnish on a fingernail. In this case, an image of the fingernail is first detected by means of a camera and converted into a processing path after image analysis, wherein an applicator then applies the paint while following the processing path. This process is complex and expensive and therefore not suitable for private use. There is therefore a need for an improved application device for liquid media and in particular for the application of nail polish.

Summary of the invention

It is an object of the present invention to provide a device for

Applying a powdery or liquid medium to provide, which is an improvement in terms of the above-mentioned disadvantages by reducing the disadvantages or even completely eliminated. According to the invention, the object is achieved by a device according to

Claim 1 solved. Specific embodiments of the invention are the subject of the additional dependent or independent claims. In a first aspect, the invention provides an apparatus for applying a powdered or liquid medium, comprising:

(A) an application element for applying a liquid or powdery medium that is mounted between two support elements and flexible in width is variable; and

(B) at least one limiting element, the side of the

(c) the applicator element is positioned and configured to adapt to the flexible width of the applicator element and to laterally confine the media application.

The device according to the invention has numerous advantages over the vessels known from the prior art.

The device according to the invention initially has an applicator element which is flexibly variable in width. This allows, during the media application, controlled either by the user or the contour of the surface, to vary the width of the media order variable and thus adapt to the contour of the surface. Thus, the device is ideally adapted to the spade-shaped contour of nails and the application can be done step and jerk-free adaptation to the shape of the finger or toenail.

This width adjustment also makes it possible to paint the nails clean with a line, which saves time on the one hand, and on the other hand minimizes the risk of paint defects.

The fast media application also has the advantage that even very fast-drying or hardening media (eg: paints with volatile solvents) can be applied. Even liquid media with even shorter processing time, which previously could not be used for application reasons, are hereby available for the first time for an application.

This change in width of the applicator organ is carried out by its uniform spreading, so that continues to be a homogeneous and thus optimal Media order results, which also meets the requirement of a bum-free job with good fining properties.

As an applicator almost all known technical embodiments can be used, such as brush, roller, sponge or spray, so that the device is widely used.

The lateral width flexibility of the applicator element also allows advantageously to use the device with the conventional media vessels, so that by narrowing the applicator device, the device can be easily inserted into the vessel opening. Especially in nail polishes with the volatile solvents, a narrow vessel opening is preferred.

In addition, the device has a laterally positioned limiting element. This prevents in a simple manner that the liquid or powdery medium overlaps on adjacent surfaces and thus provides a media application with an exact lateral boundary.

Thus, the device is widely usable for all technical purposes in which a liquid or powdery medium to be applied with an exact boundary line.

Since the device itself sets the limit, can be dispensed with external aids such as templates or tapes and it eliminates any aftertreatment. This results in an easy to perform and fast media order.

The lateral boundary elements also allow the use of elongated bristles, which can accommodate more medium accordingly. Such long bristles have hitherto not been usable in the prior art because they spread excessively and gave an unclean media order. Therefore, the applicator can absorb so much nail polish that frequent immersion of the applicator is avoided in a nail polish stock. In a preferred embodiment of the invention, the limiting element of the device comprises a guide element which detects surface structures or contours and thus can variably control the boundary based on the detected structure / contour. Especially in the case of fingernails or fingernails, the nail fold represents a clearly detectable structure. The guide element can intervene in this fold and regulate the media application in its width accordingly. This makes it possible even for inexperienced people to paint the nails exactly. The device according to the invention is relatively simple and therefore not only inexpensive to manufacture, but also user-friendly in the application.

In summary, the device according to the invention allows a quicker and better quality application of the liquid or powdered medium with simple application.

The invention in detail

According to the applicator element is mounted between two carrier elements in the device. In a preferred manner, the width of the carrier elements relative to one another allows the intermediate applicator element to be varied accordingly in its width. Alternatively, the support members may have a fixed distance and the applicator member mounted therebetween is independently variable in width.

For the purposes of the application, the width of the application element refers to that side of the application element which is perpendicular to the direction of the media application and thus defines the width of the media application.

Furthermore, the width change relates at least to the part of the application element which is in contact with the surface to be processed and thus ensures a direct transfer of the liquid or powdered medium to the surface. So it does not have the entire invention according to the invention Application element be variable in its width. In the case of a bundle of bristles, it is therefore sufficient if only the front region of the bristle bundle is varied in width.

In one embodiment, the applicator element is attached directly to the support element. In an alternative embodiment, the application element can be indirectly connected to the carrier element (s) via another element (eg via a roll axis).

In this case, the usual rod-shaped carriers, which are known in particular in the field of nail polish applicators, can be used as carrier element. As materials here wood, metal or plastic can be used. Preferred here is the use of flexible materials, such as an elastomeric material. Advantageously, this material is selected from the group comprising polyethylene such as high-density polyethylene (HDPE), polyurethane, polyesters, polyether block amides, polyvinyls, ter-polymers of ethylene, propylene and a diene (EPDM) and polymers of styrene-butadiene- Follow (SEBS-SIS). In particular, the elastomeric material has a hardness which is in the range of 35 to 90 Shore A and preferably in the range of 50 to 70 Shore A. In an equally preferred embodiment, the elastomeric material has a hardness of Shore D80.

The inventive lateral positioning of the limiting element allows adaptation to the width of the applicator element. This means that the boundary element follows the changes in the application element in width, i. in the case of boundary elements present on both sides, their distance from each other is changed to the same extent as the width of the applicator element located therebetween. In the simplest way, this requirement is met by the fact that the at least one limiting element is connected to the applicator element, wherein the distance between applicator element and limiting element is substantially unchangeable.

In a preferred embodiment, the limiting element comprises a guide element, which detects the contour and / or the structure of the surface and is designed so that it during the media application, the width of the media order flexibly adapts to the contour of the surface. Thus, it is possible that the surface itself determines the width of the media job and does not have to be actively guided by the user in width. For this purpose, the limiting element is designed tapered in the simplest embodiment, so that the pointed end engages in contours or structures of the surface and thereby gives the material order an appropriate leadership. In an alternative embodiment, the guide element is a ball or a roller. The width B _F E of the tapered guide element is chosen so that it can still correctly capture the contours / structures of the surface, but also not too pointed, as that here the surface is damaged.

In an alternative embodiment, the delimiter provides a marker for the current width of the media job. This can be done by a tip-to-tip boundary element with a marked tip, giving the user a clear indication of the width of the media job. Alternatively, the mark can be displayed on the surface to be processed. For this purpose, it is possible to use (preferably miniaturized) light sources which, starting from the device, project a light signal onto the surface and thus indicate to the user the application limits. In a particularly preferred embodiment of the invention that is

Limiting element attached directly to the side of the application element. Thus, the liquid or powdery medium discharged from the applicator can be retained by the limiting element directly and continue to be available for the media order.

In a preferred embodiment, the liquid medium is selected from the fields of cosmetic product or medical product. By way of example, mention may be made here of liquid medium: lotion, gel, mask, mascara, eye shadow, means for the care of the tooth replacement, lacquer for the dental sector, hair fixative, Hair dye, lip care product, nail varnish, nail polish remover, nail care product, nail glue, stick gel, nail oil and medical device selected from cavity varnishes, medical care varnishes and antimicrobial coatings. In a particularly preferred embodiment, the liquid medium is selected from nail varnish, nail polish, nail hardener, groove filler, nail polish remover, nail care product, nail glue, adhesive gel, nail oil, lip care product such as lipstick or lip gloss, make-up or paint for the dental field.

In an alternative embodiment, the medium to be applied is a powdered medium and selected from the group consisting of body powders, face powders, powder coatings, and in particular electrically curing lacquers and lacquers which are cured by UV light, heat or chemical processes.

In an alternative embodiment of the invention, the device is designed so that it can be applied with liquid or powdery media for non-biological applications, so for example for coatings in the field of furniture, textiles, leather goods, paper, building materials, building, metal, plastic, machinery , Motor vehicles.

In a further embodiment, the device according to the invention is suitable for applying the liquid or powdered medium on one of the following surfaces: a wall, ceiling, or floor surface of a building, a surface of a vehicle body, a surface of a furnishing, and the surface of food.

In a preferred embodiment, this surface is a surface of the human or animal body.

In a particularly preferred embodiment, this surface is the surface of foot or fingernails, teeth, skin or hair. In addition to the nails, the teeth represent a relevant field of application for the device according to the invention. The guide element can intervene here in the interdental spaces and thus allow the clean, targeted application of medically or cosmetically effective media to the teeth.

The applicator element can be designed in many different ways, and the person skilled in the art can refer to all application forms known from the prior art. Thus, the applicator element can be configured in an exemplary manner as follows: fiber bundles, bristle bundles, tassel, roller, flocked device, swab, sponge, fleece, loop, spatula or spray head.

In a flocked device flock fibers are applied to a base body with the aid of adhesive.

The application element may comprise one or more of the previously listed application forms. According to the two carrier elements, it is preferred that the application element comprises exactly two of these application forms, that is, two bristle bundles or two tassels.

Advantageously, according to a first embodiment of the invention, the applicator element is formed in a conventional manner from a tuft of substantially parallel bristles. The bristle tufts in particular have a length (L _A E) ranging from 8 to 40 mm, and preferably from 1 1 to 20 mm. In this case, the applicator forms a brush.

The applicator element may be fixed with respect to the width B _B E of the delimiting element at the rear edge, in the middle or at the front edge of the delimiting element.

The applicator element is preferably mounted centrally on the limiting element. Here, the depth of the applicator element (see Figure 10: T _A E) is preferably narrower than the width of the associated Delimiting element (see Figure 10: B _B E) - This allows the limiting element in a simple way to limit the application of paint laterally.

In one embodiment, the bundles of bristles are attached to the limitation or support member that exists between the frontal edge of the bristle bundle and the inner edge of the guide member, a distance _Δ Α Ε-ΒΕ, of preferably up to 1, 5 mm. This allows the applicator element to expand laterally by that amount before it even touches the guide element.

According to this variant, the device preferably has a tuft of about 20 to 200 and preferably about 50 to 150 bristles having a diameter ranging, for example, from 4 hundredths to 25 hundredths mm and preferably from 6 hundredths to 17 hundredths mm, generally are made of polyamide, for example of nylon ^® 6,6-6,6-10,6-12 or of nylon ^® 1 1, of polyester, of polyacrylate, of polyacetal or of cellulose acetate. The bristles may alternatively be of natural origin.

At least a portion of the bristles may have slight corrugations throughout their length. The bristles may have cross-sections whose shape is selected from the group of circular, annular, polygonal, cruciform, rectangular, multi-lobed, U, C or V-shaped shapes and / or have at least one capillary groove. The free end of the bristles that form the applicator may be in the form of a needle head, which has been achieved in particular by thermal treatment, for example by flaming. The free end of the bristles may also be formed in a tapered shape obtained, for example, by grinding or carding.

In principle, the bristle tufts can be taken both annular, for example in a circular cylindrical flexible sleeve, as well as oval, rectangular square or in another form. Preferred here is an elongated rectangle or an ellipsoid that is changed over the width adjustment to a rectangle with a modified longitudinal side or to an ellipsoid with changed eccentricity. Furthermore, the bristle bundle can also have an arcuate or C-shaped cross-section, wherein the concave underside is intended to come into contact with the convex nail surface. In a further embodiment, the bristle cross section can change its shape in a controlled manner by contacting it with the surface. Thus, a convexly configured bristle bundle (pair) can be "folded over" into a concave brush cross-section by being pressed onto a likewise convex nail surface The surface defined by the bristle ends can be completely or at least partially, for example, the shape of a straight or oblique circular cone, a truncated cone, a pyramid , a truncated pyramid or a segment of a sphere, or rather tapered, as is known from hair brushes used in painting, or also run in the manner of a spherical segment.Combinations of these shapes are also possible.For example, the area defined by the bristle ends can also be frustoconical and rounded upper area.

In a preferred embodiment, the area defined by the bristle ends is convexly curved.

In one embodiment, in the case of a convex bristle end, the guide element lies at the same height at the front or is set back by up to 2 mm (see distance A _A E-FE: convex in FIG. 10).

In an alternative embodiment, in the case of a concave bristle end, the guide element lies at the same height at the front or protrudes by up to 2 mm (see distance A _A E-FE: concave in FIG. 10).

The material which forms the bristles may contain an agent which modifies its surface condition and / or its sliding properties and / or contains its wettability with water and / or a solvent or also an antistatic agent. Advantageously, the agent which improves the sliding property of the fiber and reduces its wettability with water and solvent is included in the material of the bristles at a level of between 0.2% by weight and 15% by weight and preferably between 0.3% by weight % and 5% by weight.

This lubricant is preferably selected in the group formed by polytetrafluoroethylene, boron nitride, molybdenum bisulfate, graphite, the silicones, Walker's earth and talc.

Advantageously, the attachment of the applicator element to the carrier element is ensured, for example by gluing, but it can also be effected by any other known means commonly used for the manufacture of brushes, for example by a clamping ring or a so-called anchor method.

In a further preferred embodiment, the application element consists of at least one bristle bundle, which is connected at one end to the device and has a Aufspannhilfe, which spans the individual bristles of the bristle bundle evenly spread in a plane. The Aufspannhilfe is this, either connected to the bristles or it spans on both sides of the bristle bundle. In a preferred manner, in this case the Aufspannhilfe is glued to the bristle bundle.

This Aufspannhilfe is suitably made of an elastic material such as. An elastomer which can be elastically deformed under tensile and compressive load, but then returns to its original, undeformed shape.

In a preferred embodiment, the elastomer is selected from the group consisting of polyisoprene, polyisobutylene, isoprene / isobutylene copolymer and styrene-butadiene rubber, poly (organo) siloxanes (silicone) and combinations thereof. In a particularly preferred embodiment, the Aufspannhilfe consists of a silicone composition. In a further particularly preferred embodiment, the

Application element of at least one roller which is flexibly movable transversely to the roll axis. As a result, the roll can also produce a concave or convex application surface, or even a more complex shaped application surface. As part of the nail polish application, the roller will deform correspondingly concave in order to strike the convex nail surface optimally.

Such a roller is thus not only in width but also perpendicular to it flexibly changeable and thus particularly well suited to provide complex surfaces with liquid or powdered media.

In a roll, different technical solutions can be used for the width variability according to the invention. Thus, the roller can consist of a total of an elastic material, or be constructed accordion-like. In a preferred embodiment, it is a spiral-divided roller, wherein the spiral in terms of a spring element makes the roll in the width flexible and also represents a surface structure that does not affect the homogeneous application of the liquid or powdered medium. In a further embodiment, the roller used as an applicator element has a unwinding aid, preferably in the form of a polygon, and more preferably in the form of a star, which facilitate rolling of the roller on the surface. Preferably, this Abrollhilfe is identical to the

Delimiting elements so that the roller according to the invention is delimited, for example, by two adjacent circular delimiting elements which carry elevations (eg in the form of "star serrations") and thus facilitate unrolling. In an alternative embodiment, the unwinding aid is located at a distance from the limiting elements. Thus, in a roller as the applicator element, the tooth-carrying roller can be mounted centrally as a rolling aid on the roller. In a correspondingly thin configuration of this serrated roller, the uniform application of paint is not disturbed even with such a central arrangement.

In a particularly preferred embodiment, the tips of this unwinding aid penetrate easily into the surface intended for the media application.

In a particularly preferred embodiment, the applicator element consists of two bundles of bristles, which are fastened laterally to the inside of the two rod-shaped support elements, wherein the two rod-shaped support elements are pivotally coupled via a pivot axis and are preferably connected by at least one spring element are biased their pivotal movement.

In a further embodiment of the device according to the invention, the at least one delimiting element consists of a plate, a disc or it represents the distal end of the carrier element. In this case, the carrier element merges into the delimiting element in the distal region, the delimiting element being that region in which the application element mounted therebetween in its media order runs the risk of expanding this liquid or powdered medium to adjacent areas.

In a particularly preferred embodiment, the at least one limiting element is mounted rotatably as a preferably circular flat element about its own axis. The necessary pivotability of the two support elements and thus also the boundary elements to each other is ensured by at least one pivot axis and / or a flexible material. In this case, in a preferred manner in this pivoting two support elements / limiting elements, a voltage is built up, which counteracts the pivoting. In a preferred embodiment is used as a flexible material metal, plastic, wood or glass fiber reinforced plastic. In a preferred embodiment of the device according to the invention, at least one of the surfaces of the guiding and / or limiting element has a coating which exerts a repellent effect on the liquid or powdered medium used. For a hydrophobic medium, this is suitably an oleophobic, hydrophobic or superhydrophobic coating. In the case of a polar medium, a coating is suitable which leads to a lotus effect, ie forms a microstructure or nanostructure which is water-repellent.

In a second aspect, the invention provides a kit comprising:

a. a device according to the invention; and

b. a vessel for immersing the device (media vessel) containing the liquid or powder medium to be applied. The media vessel can take any form here, with a

Stand bottle is preferred.

Alternatively, the vessel may also serve as a cap for the pen configured device. Here, in one embodiment, the cap can simultaneously serve as a storage vessel for the liquid or powdery medium.

In an alternative embodiment, the cap is intended only as a protection or closure possibility. The liquid or powdery medium can in this case be taken from a separate vessel or is integrated in the pen, so that it is supplied from above the applicator element.

In a further embodiment, the medium vessel has a volume of between 2 and 20 ml, preferably between 5 and 16 ml and more preferably between 8 and 13 ml. In a preferred embodiment, the media vessel comprises a wiper member for stripping the liquid or powdery medium from the guide element and / or delimiting element and / or carrier element.

In a further preferred embodiment, the wiper member consists of one of the following materials or devices or a combination of these: silicone, foam, an electrostatic acting device. In a particularly preferred embodiment, the wiping member for the limiting or guiding element is designed as a gap which is arranged at a distance from the media vessel and which is preferably designed in a wave shape. As a result, the applicator element is selectively immersed in the liquid or powdered medium and receives there the medium, while the limiting or guide element is guided separately thereof through the gap, which removes both sides, possibly existing, liquid or powdery material from the applicator element.

In a further embodiment, the media vessel also has a wiper element for the application element in order to strip off excess liquid or powdery medium. This is particularly important in a cylindrical applicator element, since after immersing a roller in liquid or powdery medium in a special way a uniform distribution of the medium on the roll surface with removal of excess medium is required. The wiper member for the applicator element can be designed in this forma and material as the above-mentioned wiper members. In a roller, a scraper is preferred.

In a further embodiment, the media vessel contains a trapezoidal trough for receiving the liquid or powdery medium. Upon immersion of the device in this tub, the liquid can be received in a controlled manner by the applicator element. The trapezoidal configuration allows the device to be pulled through the trough to a controlled width of the applicator element, so that it is in this case selected width corresponds to the width of the surface to be treated. For example, when varnishing a thumbnail nail, the optimum amount of nail polish can be included here in advance definition of the amount of media. In another aspect, the invention provides an apparatus for applying a powdered or liquid medium, comprising:

(a) an applicator for applying a liquid medium

is mounted outside of two support elements and flexible in width is variable; and

(B) at least one limiting element, the side of the

(c) the applicator element is positioned and configured to adapt to the flexible width of the applicator element and to laterally confine the media application inwardly. In this embodiment, the inventive teaching with respect to the

Color order inverted. The application elements are now outside, so with respect to the two support elements located on the right and left outward. Its flexible customizable width allows two separate application tracks to be created. In this case, the media order is then bounded laterally inwards.

In a further aspect, the invention relates to a method for applying a liquid medium, comprising the following steps:

(A) immersing the application member of the device according to the invention in the liquid or powdery medium while receiving the liquid or powdered medium from the applicator element;

(B) stripping the excess liquid or powdered medium from the applicator and / or limiting element and / or guide element;

(c) applying the liquid or powdered medium to the surface by contacting the applicator element with the

Surface.

EXAMPLES

The embodiment in Fig. 1 shows the kit according to the invention consisting of the device 10 for applying the liquid medium and a media vessel 12 with a lid 11 for closing the media vessel. The device 10 is placed in the storage chamber through the opening 13 for storage. For product application, the lid 11 is removed from the media vessel 12 and the device 10 is inserted into the media vessel 12 from above and immersed there in the liquid medium, which is present in the middle trapezoidal chamber. Here, the limiting elements 14 and the guide elements are guided along the V-shaped lateral guides, which leads to a two-sided stripping of excess liquid medium from the limiting elements 14. In Fig. 2, the media vessel 22 with the opening 23 for storage of

Device shown. As shown by the cross-section in B, the round storage chamber 23 is surrounded by a hatched absorbent material which causes excess material to be removed and / or soaked with solvent to solid-dry the liquid medium prevented. The device is inserted so that the applicator element between the V-shaped lateral guide 26 dips into the liquid medium and can receive the medium there. The guide element or the limiting element is thereby introduced into the gap 201 and thus does not come into contact with the liquid medium. Remaining liquid medium is in this case stripped by pulling through the acting as a wiper member 25 gap 201. The enlarged view illustrates the position of the wiper member, in this embodiment of a foam, in the media vessel 22. In the embodiment shown in (C), the foam from the lower storage area and the upper application area forms a common foam body, which thus in contrast to the device of ( A) has no separation.

Another embodiment of the media vessel 32 is shown in FIG. In this case, the wiper 35 is integrated in the upper part of the bottle neck.

4 shows a special embodiment of the device 40 in the form of a pin with a closure cap 401, which in one embodiment can simultaneously also function as a media vessel of the pen-shaped device. The cap has in the media vessel design on the opening side a wiper 45. The support elements 441 are pivotable relative to each other here via a pivot axis 47 and connected via a flexible band 48 as a spring element. The two applicator elements 49 are each attached to the inner sides of the limiting elements 44.

In Fig. 5, in addition to Fig. 4, a Aufspannhilfe 501 is provided which distributes the individual bristles of the applicator element 59 evenly in this embodiment of the device 50 and spans in a plane. In addition, the device 50 is imaged during the media application on the schematically indicated surface 502 of a fingernail.
