EMBODIMENTS

(12) The embodiment in FIG. 1 shows the kit according to the invention comprising the device 10 for applying the liquid medium as well as a media container 12 with a cover 11 to close the media container. The device 10 is inserted through the opening 13 into the storage chamber in order to be stored. For purposes of applying the product, the cover 11 of the media container 12 is removed and the device 10 is inserted into the media container 12 from above, where it is dipped into the liquid medium that is present in the middle trapezoidal chamber. In this context, the delimiting elements 14 or the guide elements are moved along the V-shaped lateral guides, causing excess liquid medium to be scraped off both sides of the delimiting elements 14.

(13) FIG. 2 shows the media container 22 with the opening 23 for storing the device. As the cross section in B shows, the round storage chamber 23 is surrounded by absorptive material—shown by cross hatching—that ensures that excess material is removed and/or that, when soaked with solvent, prevents the liquid medium from drying up. The device is inserted in such a way that the application element dips into the liquid medium between the V-shaped lateral guide 26, where it can pick up the medium. The guide element or the delimiting element is inserted into the gap 201 so that it does not come into contact with the liquid medium. Remaining liquid medium is scraped off while being pulled through the gap 201 that functions as a scraping implement 25. The enlarged depiction illustrates the position of the scraping implement—a foam in this embodiment—in the media container 22. In the embodiment shown in (C), the lower storage area and the upper application area form a joint foam element that consequently, in contrast to the device of (A), does not have a separation.

(14) Another embodiment of the media container 32 is shown in FIG. 3. In this case, the scraping implement 35 is integrated into the upper part of the neck of the bottle.

(15) FIG. 4 shows a special embodiment of the device 40 in the form of a pen with a closure cap 401 that, in one embodiment, can concurrently also serve as the media container of the pen-shaped device. In the media container embodiment, the closure cap has a scraping implement 45 on the opening side. Here, the support elements 441 can pivot relative to each other around a pivoting axle 47 and are joined via a flexible strip 48 in the form of a spring element. The two application elements 49 are each affixed to the insides of the delimiting elements 44.

(16) As an augmentation to FIG. 4, FIG. 5 provides a spreading aid 510 that, in this embodiment of the device 50, uniformly distributes the individual bristles of the application element 59 and spreads them out in a plane. Moreover, the device 50 is depicted during the media application onto the schematically indicated surface 502 of a fingernail.

(17) In contrast to FIG. 5, the device 60 in FIG. 6 does not have one but rather two application elements 69, which are affixed laterally on the two delimiting elements 64 and which fan open during the media application onto a schematically indicated fingernail surface 602, thereby forming an application surface.

(18) FIG. 7 shows another embodiment of the device 70 in which the application element 79 is affixed as a bristle bundle that extends from the stem 701, and during its media application, it is delimited by two delimiting elements 74 that each have a pivoting axle 77.

(19) Another embodiment of the device 80 is shown in FIG. 8, in which the two bristle bundles, as application elements 89, are held in sleeves which, in turn, are affixed to the inside of the support elements 841. These support elements, which run in parallel, are made of a flexible material and, in their end position, they open up into the delimiting elements 84.

(20) FIG. 9 shows the embodiment of the device 90 with a roller-shaped application element 99 in the initial position as well as on a schematically indicated surface 902 of a fingernail during the media application. Here, the roller 99 is configured with spiral-shaped indentations that allow the width to be varied. Furthermore, this roller is mounted on a flexible rotating axle 901 that stretches between two support elements 941. The delimiting elements are configured at both ends of the roller as circular end plates 94 that, as guide elements, have an outer edge 96, as a result of which they can follow along a surface structure or contour such as a groove, fold or edge.

(21) Based on the device shown in FIG. 6, FIG. 10 shows dimensions or distances that are relevant to the invention. The depicted device has two bristle bundles as the application element having a length L.sub.AE. The bristle bundles are affixed in such a manner that a distance Δ.sub.AE-BE is formed between the edge of the bristle bundles and the inner edge of the guide element. The guide element opens up into a tip having the width B.sub.EE. In the case of a pair of bristle bundles that end concavely or convexly, the guide elements are arranged on the front at a distance Δ.sub.FE-AE:convex or Δ.sub.FE-AE:concave thereto. In (B), a device shown in a perspective view has a delimiting element whose width B.sub.BE is wider than the depth of the bristle bundles affixed to the inside thereof as application elements having a depth T.sub.AE.

Definitions

(22) In the context of the present invention, a delimitation of the media application towards the “outside” means that the media is prevented from being spread from the side of the delimiting element facing the application element to the side of the delimiting element facing away from the application element.

(23) The person skilled in the art can glean additional variants of the invention and their execution from the preceding disclosure, from the figures and from the patent claims.

(24) In the patent claims, terms such as “encompass”, “comprise”, “contain”, “have” and the like do not exclude additional elements or steps. The use of the indefinite article does not preclude the plural. Each individual device can execute the functions of several of the units or devices cited in the patent claims. The reference numerals indicated in the patent claims are not to be construed as a limitation of the means and steps employed.
