Definitions

  • the invention relates to a process for the preparation of an applicator for cosmetic products, in particular for cosmetics for making-up of eyelashes, eyebrows and hair, wherein fibers are held to form a contract body by means of a carrier body and brought into a brush-like shape and an applicator.
  • Various forms of applicators for applying cosmetic products are known. These have, for example, a comb-like or a sponge-like shape. Moreover, it is known to make brush-type applicators in which fibers are inserted into a loop of wire and the wire loop is then twisted, resulting in a round brush. Depending on the position of the fibers, this brush may have a closed, an open or even a semi-open surface structure. Other embodiments of the carrier body for fixing the fibers are also possible.
  • the brush-like applicators vary more or less depending on the application. Applicators for applying a cosmetic product on a cheek usually have a rather brush-like shape. Applicators for applying a cosmetic product to eyelashes, on the other hand, have fewer and stiffer fibers than the brush-type applicators.
  • the invention is therefore based on the object to provide a method by which the application of a cosmetic product can be further improved.
  • This object is solved by the characterizing features of claim 1, advantageous developments emerge from the dependent claims.
  • the core of the invention is to modify the fibers after joining with the carrier body by a rolling, embossing, punching and / or printing process with regard to its shape, surface texture and / or structure.
  • the rolling, embossing, stamping and / or printing process may relate to the carrier body and / or the fibers or at least a part of the fibers.
  • the processes mentioned, namely the rolling, embossing, stamping and printing processes are referred to in the following as summarizing modification processes.
  • the term modification process comprises in one and a plurality of one or a combination of the aforementioned processes.
  • the modification processes result in new surface structures that lead to improved uptake of the cosmetic product.
  • the fibers have a substantially equal length after their production, the length of the fibers of course varying by a predetermined average with a certain variance.
  • the variance increases again after the introduction of the fibers into the wire loop, since the fibers extend at different distances into the wire loop.
  • the fibers it is possible to punch the fibers so that they have substantially two different lengths. For example, it is possible to shorten the fibers in the center of the applicator more than in the edge regions, whereby the application body of the applicator receives a double lobe-like shape.
  • Other alternative embodiments such that the applicator tip is tapered by the fibers are shortened to ever shorter lengths to the tip of the applicator, are also conceivable.
  • the rolling process three different modifications can be achieved. First of all, the fibers themselves can be rolled to increase their surface area. A fiber is usually extruded in the course of production, and thus has a round cross-sectional shape.
  • the rolling process turns the round cross-sectional shape into an oval shape, thereby increasing the surface area of the rolled fiber. This allows a single fiber to absorb more cosmetics.
  • the fibers can thus be concentrated in two or three areas as seen in cross-section, the applicator can thus be in the form of a kind of double comb.
  • the rolling process does not change the shape of the fibers but rather the shape of the carrier body itself.
  • a corrugated structure can also be rolled onto the carrier body, whereby the surface density of the fiber tips is modified.
  • the surface of the applicator has areas of varying densities of fiber tips due to such a curving process of the carrier body, and therefore the density of the cosmetic product to be applied is changed, assuming that the tips of the fibers absorb the cosmetic product approximately evenly.
  • the rolling process can also be configured as a bending process.
  • the embossing process allows the change in the surface structure of the fibers, for example by embossing elongated or punctiform depressions in the fibers.
  • more cosmetic mass accumulates than at the smooth areas or surfaces of the fibers, whereby the application effect of the individual fibers and thus also of the applicator is improved.
  • further fiber sections can be applied to the fibers connected to the carrier body.
  • This application can be done by means of the rolling or embossing process.
  • Also through the fiber sections takes place an increase in surface area of the fibers, whereby the order of the cosmetic product can be improved.
  • the fiber sections may be applied over the entire length of the fibers, but it is preferred to apply them only in the region of the tips of the fibers. The area of the tips is the front third of the body facing away from the carrier body.
  • the fibers which modify the surface structure.
  • These may be paint, color and / or rubbery substances.
  • the substances must be able to adhere to the fibers and be suitable for receiving the cosmetic product.
  • the absorption capacity of the fibers can be changed selectively or even over the entire surface of the fibers, similar to the embossing process.
  • the fibers are able to take up the bulk of the cosmetic product.
  • the modification processes can be used individually or combined. In particular, it is possible to carry out all the mentioned modification processes on a single applicator. Alternatively, it is possible to perform one or more modification operations on a portion of the applicator and to apply one or more portions of the applicator through another or another combination of modification operations.
  • the invention relates to an applicator, which is prepared from carrier body and fibers, and in which the carrier body and / or the fibers by a rolling, stamping, punching and / or printing operation in terms of its shape, surface texture and / or structure based on the state before the rolling, embossing, punching and / or printing process is modified.
  • FIG. 1 shows an applicator 1 with a handle 2, a wire loop 3 and a plurality of fibers 4.
  • the fibers 4 are inserted into the wire loop 3 and the wire loop 3 is twisted.
  • the wire loop 3 forms a carrier body 5.
  • the carrier body 5 holds the fibers 4, which together with the carrier body 5 form the application body 6 of the applicator 1.
  • the applicator body 6 is shown below, but the term applicator can still be used in connection with the following figures. The difference is only in the handle 2 or arbitrarily shaped receiving area of the carrier body. 5
  • FIG. 2 shows the applicator 1 according to FIG. 1 in cross-section, in the region of the application body 6. Accordingly, in the middle of the applicator 1, the carrier body 5, the fibers 4 go radially outward. With the same length of the fibers 4, these form a relatively homogeneous surface. 7
  • FIG. 3 shows an edited by a punching applicator 1.
  • the length of the fibers 4 was shortened in the middle of the application body 6, so that the application body 6 seen in the longitudinal direction in the edge regions eighth and 9 has a larger diameter than in the central region 10.
  • the edge regions 8 and 9 may also have been treated by a punching process, so that the surface 7 of the applicator 1 was also smoothed there.
  • the transition region between the edge regions 8 and 9 and the central region 10 can be made fluent or edged.
  • FIG. 4 shows the applicator according to FIG. 3 in cross section. Clearly visible are the different diameters of the edge regions 8 and 9 and of the central region 10. The dashed connecting lines between the FIGS. 3 and 4 clarify this relationship again.
  • FIG. 5 shows a stamped applicator 1 in a second embodiment.
  • the fibers 4 were removed in the upper half of the applicator 1 in two segments of the circular cross-section, so that the shape of an upside-down cork is produced.
  • an applicator 1 which has the usual Bürstchenform on the one hand and on the other hand has a rather comb-like appearance.
  • FIG. 6 shows that the cross section of the applicator 1 according to FIG. 5 in the middle of the application body 6 shows, clearly visible.
  • the applicator 1 according to FIG. 7 was rolled so that the fibers 4 were concentrated in their Abstehraum on two areas.
  • the fibers 4 were rolled sideways as in a center peak so as to have a shape similar to a suit fly in cross section.
  • the fibers 4 are characterized in the areas 11, as in FIG. 8 is shown, compacted and greatly thinned in areas 12 to no longer available.
  • the advantage of this embodiment is that applicators 1 with a high fiber density can be produced without this density exceeding the capacity of the carrier body 5.
  • FIG. 9 shows an applicator 1, in which the carrier body 5 has been bent. The bending is achieved by means of a rolling process, which can also be configured as a simple pressurization without rotating roller body.
  • FIG. 10 shows the applicator 1 according to FIG. 9 in cross section.
  • FIG. 11 shows an alternative embodiment to that in FIG. 9 shown bend.
  • the carrier body 5 is bent in a wave or sinusoidal manner in the longitudinal direction.
  • the indented sections 13 thereby arise areas of higher fiber density and in the raised portions 14 areas of lower fiber density.
  • the mass of cosmetic mass adhering to the fibers, which can be applied correlates. Accordingly, an applicator 1 designed in this way has sections with a high content of cosmetic mass and sections with a low content of cosmetic mass.
  • FIG. 12 shows the corresponding applicator according to FIG. 11 in cross section. More precisely, the cross sections of the in FIG. 11 Shown with A and B shown positions. Due to the bending in the longitudinal direction, the applicator 1 in the side portions 15 on an unchanged, so neither enlarged nor reduced, density of fibers 4, as before the rolling or bending operation. As a result, a longitudinally rolled applicator 1 even has three different fiber densities if a uniform fiber density was present before the rolling process.
  • FIG. 13 shows a known fiber 4 before a rolling process
  • FIG. 14 the corresponding fiber 4 after the rolling process shows.
  • FIG. 15 shows two attached to the support body 5 fibers 4, where fiber portions 16 have been applied.
  • the fiber sections 16 are much shorter and preferably also thinner fibers compared to the fibers 4. These are preferably made of the same material as the fibers 4.
  • synthetic fibers such as polyamide or elastomers, as well as natural fibers, such as. As goat hair used.
  • the fiber sections 16 are attached to the fibers 4 by a rolling or embossing process. During the rolling process, the fiber sections 16 are simply pressed against the fibers 4 so tightly that a superficial connection is formed. During the embossing process, on the other hand, pressure is exerted selectively, the fibers 4 being provided with punctiform depressions.
  • a fiber section 16 lies on a fiber 4 where the punctual pressure is exerted, then the fiber section 16 is also connected to the fiber 4. If one covers the entire fiber 4 with fiber sections 16, then only part of the fiber sections 16 is connected to the fiber 4 after the embossing process. This is desired. A complete covering of the fibers 4 is not necessary.
  • the fiber sections 16 are attached only in the region of the tips of the fiber 4, in particular in the front third.
  • the tip region is to be understood as the region facing away from the carrier body 5.
  • the attachment of the fiber sections 16 can be controlled, for example, by the fact that the embossing process takes place only in this area of the fibers 4.
  • FIG. 16 shows a known fiber 4 before a rolling process
  • FIG. 17 the corresponding fiber after the rolling process shows.
  • the round cross-section was converted into an oval cross-section, whereby a surface enlargement of the fiber 4 takes place.
  • FIG. 18 shows a fiber 4, which was printed with color 17.
  • paint or rubber can be used.
  • the color 17 may also cover a whole section, for example the area of the tip of a fiber 4.
  • FIG. 19 shows two fibers 4, in which by a stamping puncture recesses 18 were impressed. If two fibers lie in sections one above the other in such an embossing region, for example in the region 19, the fibers 4 are connected to one another. This results in a scrubby fiber composite with a changed stiffness compared to individual fibers 4. If an applicator 1 has a multiplicity of such fiber composites, then overall the rigidity of the application body 6 is increased.
  • a stamping operation can be used with which the surface 7 of the application body 6 is smoothed again.
  • the cross-sectional shape of the untreated fibers is not limited to circular shapes, but any other shapes such as triangle, rectangle or circles with recesses may be provided. Also in the longitudinal direction, the fibers may have a different shape than described.
