Definitions

  • the invention relates to a cosmetic brush for applying powdery or liquid cosmetics with the further features of the preamble of patent claim 1.
  • cosmetic brushes in particular mascara brushes for applying liquid cosmetics to the eyelashes, consist essentially of spirally entangled wires which are round in cross section and into which the fibers or bristles are clamped between their two ends.
  • the free ends of the bristles projecting outward are also formed spirally around the wire core.
  • the main task of a mascara brush is to absorb a certain amount of mascara and apply it evenly to the eyelashes. However, this is made more difficult by the incomplete, spiral arrangement of the bristles.
  • the invention has for its object to provide a cosmetic brush with the features of the preamble of claim 1 in such a way that the fibers or bristles, which are comprised of at least two spirally wound wires, fan out relatively broadly in a simple constructive manner, as a result of which a closed one Brush surface results.
  • the core of the invention it is considered to be the core of the invention to provide at least one wire section of the wire core with a non-circular cross-section.
  • the size and / or shape of the cross section can also vary in the longitudinal direction of the wire. It is thereby advantageously achieved that the fibers or bristles which are jammed in the entangled drahab fan out relatively broadly to the outside. The bristle tips are therefore at a greater distance from one another, so that the bristle pattern on the surface of the bristles appears more even.
  • the fanned out bristles enable the mascara to be applied evenly and better to the eyelashes. This design also counteracts sticking of the bristles.
  • a corresponding adaptation of the bristle shape is not necessary for this embodiment.
  • the cross section of the wire section can be triangular, quadrangular or polygonal. Such a shape can be given to the wire, for example, by pulling the wire through a corresponding drawing nozzle or drawing ring. This has neither high manufacturing costs nor material loss.
  • a rounded design of the corners of the wire cross-section means that the individual bristles are fanned out at a different angle than with the sharp-edged wire. In addition, this rounded shape protects the pinched fibers and thus counteracts breaking of the fibers by incisive, pointed edges of the wire sections tangled together.
  • Fanning out the bristles or fibers also results in a wire cross section that has a circle with lateral recesses. These recesses can be round or square in shape. The fanning out of the bristles increases with increasing number of recesses or with increasing size of the recesses on the wire cross section.
  • the different design options of the wire cross-section make it possible to produce different bristle patterns on the surface of the bristles or fibers.
  • a less pronounced fanning out reveals the spiral arrangement of the fibers, whereas a fanning out leads to a higher static distribution of the bristle tips and thus a uniform surface structure.
  • differently viscous mascara liquids can be used.
  • a wire section can also be made out of round by being twisted strongly in itself.
  • the fibers which are held in the double twisted wire sections have a particularly uniform distribution around the wire core at their bristle tips.
  • Such a double twisting of the wire sections is easy to implement in terms of production technology and is associated with only a small additional cost.
  • a grooved surface of the wire section leads to the desired uniform bristle pattern at the bristle tips. Particularly good results with regard to the bristle structure are achieved if non-round wire sections are additionally twisted.
  • the outer end of the wire core on which the brush part is arranged is rounded and does not have to be additionally covered by a protective cap.
  • the fibers or bristles can have both a round and a non-circular fiber cross-section, with the fibers being fanned out in each the case is guaranteed due to the design of the wire cross section. In addition, however, an out-of-round fiber cross-section can lead to a further fanning out of the fibers.
  • the mascara can first be applied with the longer bristles and then any irregularities can be corrected with the shorter bristle part.
  • a simpler handling is also given because the shorter bristle part does not run the risk of touching other areas on the eye or contact lenses during use of the long bristle part.
  • the fibers consist of natural fibers, for example hair or natural bristles. It is also possible that synthetically produced fibers, in particular plastic fibers, form the bristle part. Here there is also the possibility of making the diameter of the fibers variable during manufacture. This is particularly advantageous for liquid cosmetics with different viscosities, since the required fiber strength can be adapted to the respective cosmetic liquid. For powdery cosmetics, for example, fibers with broad bristle tips can be used.
  • Nylon fibers are provided as plastic fibers, which are characterized by their relatively simple production method and their elasticity. We would also like to point out their particularly good skin tolerance. The invention is explained in more detail using an advantageous embodiment in the drawing figures. These show:
  • FIG. 1 shows a side view of the application brush according to the invention
  • FIG. 2 shows a side view of the application brush according to the invention with an alternative bristle pattern to FIG. 1;
  • Fig. 4 wire cross-sections of Figure 3 with rounded corners.
  • Fig. 5 shows a cross-grooved wire cross section
  • Fig. 6 is a side view of a longitudinally grooved wire section.
  • the wire core 2 consists of spirally entangled wire sections 3a and 3b, in which a plurality of fibers 5 or bristles are clamped between their two ends.
  • the pinched areas of the fibers 5 adapt to the spiral entanglement of the wire sections 3a, 3b, which can be seen in the side view in FIGS. 1 and 2.
  • the unclamped areas of the fibers 5 fan outward towards their bristle tips, which is caused by the non-circular cross-section 6 of the wire sections 3 a and / or 3 b.
  • the protruding bristles 5 are arranged radially around the wire core 2.
  • FIGS. 3, 4 and 5 Only non-circular wire cross-sections 3a, 3b possible for fanning out the fibers 5 according to FIG. 1 are shown in FIGS. 3, 4 and 5. Such non-circular wire sections 3a, 3b can be obtained by wire drawing using appropriate matrices. In Fig. 3, a triangular, square and hexagonal wire section 3a, 3b is shown.
  • FIG. 4 shows the geometric shapes of the cross sections 6 according to FIG. 3, but with rounded corners. Such a rounded wire shape according to FIG. 4 protects the bristles 4 clamped in between.
  • FIG. 5 Another alternative of a non-circular wire cross section 6 is shown in FIG. 5, which shows a circle with lateral recesses 8. Only two or more recesses 8 can also be provided, each with a different degree of fanning out of the fibers 5. Furthermore, there is also the possibility of making the wire cross-section 6 out of round by twisting the wire sections 3a, 3b into one another. This type also leads to a certain irregularity in the longitudinal direction of the wire section 3a, 3b and accordingly increases the fanning out of the bristles 5.
  • a change in the size and / or shape of the cross section 6 in the longitudinal direction of the wire section 3a, 3b also causes the bristles 5 to fan outward.
  • This design possibility of the wire section 3a, 3b is illustrated in FIG. 6 in that the surface 7 has a transverse groove structure.
  • the different cross sections 6 of the wire sections 3 a, 3 b lead to different bristle patterns, as can be seen from FIGS. 1 and 2.
  • FIG. 2 shows a greater fanning out of the bristles compared to FIG. 1 and thus an even better static distribution of the bristle tips.
  • the two wire sections 3a and 3b are formed from a folded wire. This results in a round end at the tip of the wire core 2, which also firmly clamps the bristles 5 at the outer end of the brush part 4.
  • the fibers 5, which have a round and / or a non-circular fiber cross section, can also be clamped off-center in the wire sections 3 a, 3 b. This results in an asymmetrical brush pattern in the axial longitudinal direction of the wire core 2. Since the fanning out of the fibers 5 is mainly caused by the non-circular cross sections 6 of the wire sections 3 a, 3 b, any type of fibers 5 can be used. It is therefore possible to have the fibers 5 made of natural fibers, the shape of which has already been fixed, or of artificial fibers 5, the shape of which can still be influenced during manufacture. Plastic fibers, preferably nylon fibers, are used in particular as artificial fibers.
