  • a brush of this kind is for example from the US Pat. No. 7,465,113 B2 known.
  • the nail polish brush disclosed therein has a shaft which can have different shank cross sections. Basically, a roughing shank with a circular cross-section is first produced in the production. This crude shaft is then brought to its final shape by compression, for example, flat by means of a press beam or punctiform. Due to the central compression or squeezing of the existing plastic material shaft arise along the contact surfaces between the press shop train, such as press punches and the shaft bulges, which extend in the form of longitudinal grooves along the shaft longitudinal axis and are bounded by a cross-sectionally arcuate wall portion of the shaft.
  • the compression of the shank is carried out for the purpose that the hair body shot into the shank possesses, as far as possible, a non-circular cross-section, which makes it possible to apply lacquer to a user's nail flatly.
  • the object of the invention is to provide a brush of the type mentioned, which provides a high storage capacity of the liquid to be applied and in which the liquid flow is optimized.
  • the brush according to the invention is characterized in that more than two longitudinal grooves are arranged distributed over the circumference of the shaft.

  • the longitudinal grooves can be introduced equal.
  • the shaft has an elongate shank cross section having two longitudinal sides and two narrow sides.
  • the shank is expedient to produce the shank equal to such an elongated shank cross section, without first pressing together a circular shank by suitable pressing tools on the elongated shape.
  • At least two longitudinal grooves are provided on the longitudinal sides and also at least one longitudinal groove is also provided on the narrow sides.
  • at the longer longitudinal side lends itself to form two or more longitudinal grooves, while on the short narrow side one or possibly also two longitudinal grooves can be provided.
  • the elongate shaft cross-section is oval or rectangular.
  • the shaft cross-section is divided by X and Y coordinates of a Cartesian coordinate system into four quadrants, wherein more than one longitudinal groove is formed in each quadrant.
  • the longitudinal grooves it is possible for the longitudinal grooves to be distributed uniformly over the circumference of the shank.
  • At least two longitudinal grooves are formed in each quadrant, of which the one longitudinal groove in the adjacent one and the other Longitudinal groove in the other adjacent quadrant stretch.
  • the receiving recess for the hair body is elongated, with two recess longitudinal sides and two recess narrow sides.
  • the recess longitudinal sides are convex or concave.
  • FIGS. 1 to 6 show a first embodiment of the brush 11 according to the invention.
  • the brush 11 is made as an injection molded part of plastic material, such as polyethylene, in one piece and has an elongated shaft 12, which according to the first embodiment has an elliptical or oval shaft cross-section.
  • the upper end of the shaft 12 extends in a to a shaft longitudinal axis 13 rotationally symmetrical nozzle 14.
  • the nozzle 14 has a handling portion 15, through which the nozzle 14 is gripped and thus the integrally connected to the nozzle 14 shaft 12, so ultimately the entire brush 11 can be handled.
  • a cylindrical seal portion 16 is formed, which has over a part of its length an outer diameter which is slightly smaller than the inner diameter of a neck portion (not shown) of a Liquid storage container, such as a nail polish bottle or the like, in which the brush 11 is inserted.
  • the sealing portion 16 is conically formed in the region of its free end, whereby the introduction into the neck region of the liquid reservoir is facilitated.
  • the nozzle 14 opposite shaft end 17 of the shaft 12 in the axial direction of the shaft longitudinal axis 13 aligned receiving recess 18.
  • the receiving recess 16 tapers from the free shaft end 17 to the inside.
  • the receiving recess 18 is elongate and has two recess longitudinal sides 19a, 19b and two recess narrow sides 20a, 20b.
  • the receiving recess 18 has a rectangular cross-section.
  • a hair body 22 consisting of a plurality of hairs 21 is received by means of a receiving portion 23.
  • the receiving recess 18 may be formed, for example, as a punched hole.
  • the attachment of the hair body 22 in the receiving recess 18 is advantageously carried out with the aid of a wire clamp, which einkrallt on the one hand in the material of the shaft 12 and on the other hand holds the hair 21 in the hair body 22.
  • the hair body 22 has an application section 24 opposite the receiving section 23, via which liquid, for example nail varnish, removed from the liquid reservoir via the brush 11 is applied to the surface to be wetted, for example a nail of a user.
  • liquid for example nail varnish
  • the hair body 22 has an application section 24 opposite the receiving section 23, via which liquid, for example nail varnish, removed from the liquid reservoir via the brush 11 is applied to the surface to be wetted, for example a nail of a user.
  • liquid for example nail varnish
  • the shaft 12 has an oval or elliptical shaft cross-section.
  • the shaft 12 is formed by means of plastic injection molding in this form, wherein the longitudinal grooves 25 are introduced equal during the manufacture of the shaft 12 with. It is therefore expressly not intended to first produce a circular tubular shaft, which is then pressed by means of suitable pressing tools into the final shape.
  • the longitudinal grooves 25 are distributed over the circumference of the shaft 12.
  • the longitudinal grooves 25 serve for the liquid transport of liquid taken up from the liquid storage container. At high liquid level in the liquid reservoir not only the hair body 22 immersed in the liquid, but almost the entire shaft 12. If the brush 11 is then pulled out of the liquid reservoir, adheres the substantially viscous liquid, such as nail polish, both on the shaft 12 and on the hair body 22. During the subsequent application of liquid to the surface to be wetted, the liquid stored in the hair body 22 is first applied.
  • the longitudinal grooves 25 As a result of the longitudinal grooves 25, the liquid stuck to the shaft 12 runs channeled in the direction of the hair body 22, so provides liquid for the hair body 22, whereby the order duration is extended until the next immersion of the brush 11 in the liquid reservoir.
  • the storage capacity of the shaft 12 of the brush 11 according to the invention is significantly increased, since the longitudinal grooves 25 provide additional storage space available.
  • the longitudinal grooves 25 are bounded in each case by a wall section 26, which is curved in cross-section, of the shank 12.
  • a wall section 26 which is curved in cross-section, of the shank 12.
  • the arcuate completion of the longitudinal grooves 25 prevents clogging of the longitudinal grooves 25 with liquid, which can then dry, whereby the effective transport cross section for the liquid with time is getting smaller ,
  • the shank 12 has an elongate shank cross section having two longitudinal sides 27a, 27b and two narrow sides 28a, 28b, which according to the first exemplary embodiment is shown by way of example in the form of an oval or elliptical shank cross section. According to the first exemplary embodiment, three are each provided on the longitudinal sides 27a, 27b, and one longitudinal groove 25 is formed on each of the narrow sides 28a, 28b.
  • the shank cross-section can be divided into four quadrants 29a-29d by X and Y coordinates of a Cartesian coordinate system.
  • each quadrant 29a-29d more than one longitudinal groove 25 is formed.
  • an equal number of longitudinal grooves 25 are formed in each quadrant 29a-29d, namely a total of two longitudinal grooves.
  • Characteristic here is that a longitudinal groove 25 is completely formed in each quadrant 29a - 29d, while the left and right of the longitudinal grooves 25 formed in the longitudinal direction in the quadrant 29a-29d are each divided by two quadrants 29a-29d, whereby each quadrant is assigned, in addition to the longitudinal groove 25 completely contained, two further 0.5 longitudinal grooves.
  • the longitudinal grooves have different radii of curvature.
  • the longitudinal grooves 25 formed on the shank narrow sides 28a, 28b may have a smaller radius of curvature than the longitudinal grooves 25 present on the shank longitudinal sides 27a, 27b.
  • FIG. 7 shows a second embodiment of the brush 11 according to the invention.
  • the shank cross section of the shank 12 likewise has an oval or elliptical shank cross section.
  • the longitudinal grooves 25 formed there are provided with significantly larger radii of curvature, whereby the storage volume for liquid is further increased.
