Definitions

  • the invention relates to a novel wire core brush whose application organs consist of filament, but unlike the hitherto customary bristles, each have no unilaterally projecting ends, which could be piksen, but the shape of a loop.
  • a core wire brush is provided with a core of at least two wires or wire legs twisted together, between which a plurality of filament existing order organs are kept clamped, each having the shape of a preferably completely self-contained loop, and their ends both firmly with the Wire core are connected.
  • a plurality of each forming a loop applicator members of a single filament which is clamped in one piece between the wires twisted together.
  • the whole brush consists of a single, continuous filament or at most of two such filaments and not more.
  • all loop-forming applicators consist of a single filament, which is clamped in a continuous piece between the wires twisted together.
  • filament has a double meaning in this application. On the one hand, it has a broad meaning and marks every broadly band-like material, such as a thread, which has been formed from a film. On the other hand, it preferably has a closer meaning, namely, as is customary in brush construction. The term then refers to a single, endlessly made fiber.
  • the single filament is first given a spiral shape, which is preferably permanent. This is compared to a filament merged only temporarily to a spiral one more even formation and orientation of the loops in the course of twisting achieved.
  • it uses a cold core and the heat treatment is carried out from the outside by exposing the filament wound on the core of hot air, hot steam or a suitable heat radiation.
  • a chemical treatment such as an acidic permanent wave, which permanently imposes the spiral shape on the filament.
  • the core used for this treatment may have the shape of a cylinder or a cone, or any other cross-section that depicts the desired shape of the loops.
  • the filament may be extruded in a spiral.
  • the filament is threaded onto one of the wires to be twisted together, so that this wire completely or at least substantially completely penetrates the enclosed by the spiral shape of the filament interior (if individual windings are not threaded with, this is patent law irrelevant, but causes a unattractive appearance).
  • the individual spirals migrate during twisting the individual wire windings along and are pulled fan-shaped in this way, so that the individual spirals distribute in the circumferential direction and a helix form. Between the individual turns of the helix remains a loop-free gap, which also has the form of a helix.
  • Each turn forms a completely self-contained loop, which begins at the soul from the wires and ends here again.
  • a plurality of loops is formed, preferably at least 10 loops, better at least 30 loops are formed in this way.
  • all loops of the applicator are thus formed which, in many cases, no longer has any further application organs consisting of filament.
  • each filament is formed in this way a plurality of loops, preferably at least 10 loops, better at least 30 loops.
  • the applicator has no further filament-type applicators. Special effects arise here when differently colored filaments are used.
  • the filament has the shape of a wound by a plurality of revolutions, preferably at least 50-fold spiral wound, which is attached to one of the wires, so that this wire passes through the interior of the spiral, whereupon the Wires have been twisted together.
  • penetration is understood as a complete penetration or an at least substantially complete penetration. The latter is in any case if only individual turns in o. G. Senses have not been threaded with.
  • the individual loops each have an at least substantially circular shape.
  • diameter differences of +/- 10% within a single loop are not critical.
  • the wire core brush according to the invention has a significantly increased mass storage capacity.
  • the geometrically substantially ordered labyrinth of the successive loops of the helix is also able to store relatively low-viscosity liquids to a considerable extent and deliver it again at the point of application, in particular, as soon as the loops locally deformed by the forces occurring during application become.
  • the loops form a helix, between the turns of which a loop-free gap remains, which also has the form of a helix.
  • the loops each lie in a plane which is opposite to the pitch of the wire core.
  • each of these loops lies in a plane which is substantially perpendicular to the drill axis (+/- 20 °, better still only (+/- 15 °).
  • a preferred embodiment is that the wires twisted together additionally cut Keep filaments clamped forming bristles having a radially projecting free end.
  • the variant described above can be produced even more efficiently, if not additionally cut filaments are inserted between the wire legs / wires to be twisted, but at least a portion of the initially completely self-contained loops of the finished twisted applicator is subsequently cut and / or subsequently ground and / or or is trimmed, preferably in the sense of a trims determining the contour of the bristle trim.
  • a particularly preferred variant is characterized in that at least part of the initially completely self-contained loops of the ready-twisted applicator has subsequently been subjected to hot deformation in order to change its shape and / or orientation relative to the axis of the drill.
  • the self-contained loops can be heated more strongly from a filament for the purpose of hot deformation than from cut filaments existing bristles having a free end. Because the free ends overheat quickly, so that forms a ball of already molten material at the free ends of the bristles, which is why each of the treated bristles after cooling down looks like a pin with a head, which is often undesirable.
  • the closed filaments endure higher temperatures without this happening, providing a greater degree of freedom the hot deformation results, ie, the more heated loops can be deformed more intense.
  • the or at least one of the integrally forming a plurality of loops filaments is a shape memory polymer.
  • a shape memory polymer very interesting effects, eg.
  • the cross section of the loops i.e., the cross-section bounded by the loops
  • the shape memory polymer returns to a circular cross section of each loop at higher temperatures.
  • a loop-shaped shape memory polymer with its shape memory effect can develop particularly high forces that can be used to push aside or deform other, completely passive bristles in the environment.
  • a cosmetic system consisting of an applicator with a wire core brush according to the invention, a cosmetic container and a scraper, which is characterized in that the scraper is particularly soft, preferably soft elastic and in particular of nitrile butadiene (NBR) or a comparable material.
  • NBR nitrile butadiene
  • FIG. 1 shows a brush according to the invention in the direction parallel to the core of twisted wires.
  • FIG. 2 shows the spiral wound filament and the two wires 1 and 2 before twisting.
  • FIG. 3 shows the same thing as Fig. 2 , in side view.
  • FIG. 4 shows a variant in which two independently wound into a spiral filaments are used.
  • FIG. 5 shows schematically, preferably for all embodiments, that the loops each lie in a plane which is opposite to the increase of the wire core.
  • FIG. 1 shows a wire core bust 6 of the invention
  • FIG. 1 shows the two wires twisted together 1 and 2 and also illustrates which pattern forms the single helical filament used here, when you look parallel to the drill axis D and when it has been threaded onto the wire 1 and the wires 1 and 2 have been twisted thereafter , It can be seen very clearly that directly adjacent loops 3, 4, viewed in the direction of the drill axis D perpendicular to the plane of the drawing, overlap each other at least to 50% and in general even to at least 70%.
  • the loops are circular, which was previously not possible. Depending on which shape was used for the production of the spiral shape of the filament, however, the loops can also be given a different shape in a targeted and controlled manner.
  • this applicator is preferably designed such that it is filled with a sequence of preferably at least 50, preferably at least 100, loops, all of which are arranged such that two immediately adjacent loops each span planes, which are not aligned parallel to each other, cf. also Fig. 5 and the associated designs. Angular differences up to 1 °, in some cases up to 2 ° between the planes of two adjacent loops can occur.
  • FIG. 2 shows the spiral wound filament and the two wires 1 and 2 before twisting. It is clearly seen here that only the wire 1 has been inserted into the helical filament while the wire 2 has been applied laterally thereto.
  • FIG. 3 shows the same, in side view.
  • the wires 1 and 2 are preferably not two loose, separate wires, but the two legs of a single, bent in the shape of an elongated U wire.
  • the drill axis D is visible.
  • FIG. 4 shows a variant in which two independently wound into a spiral filaments are used, one of which was threaded onto the wire 1 and the other on the wire 2, so that each of the two filaments is penetrated by another wire. After that, the wires are twisted.
  • FIG. 5 shows schematically that the loops each lie in a plane which is opposite to the increase of the wire core. This can be seen in the FIG. 5 at the angles A and B.
  • the pitch of the wire core encloses with the drill axis an angle A, which may be positive, then includes the plane in which the loops lie, with the drill axis D an angle B, which is negative contrast.
  • the angle A is negative and the angle B is positive.
  • twisting can be done in a clockwise or counterclockwise direction.
