Definitions

  • the invention relates to a brush for the transfer of liquid or pasty media, in particular of decorative cosmetics such as mascara, with a plastic carrier rod-shaped carrier having on its outer side a plurality of plastic, radially outwardly projecting, spaced fingers , And with a stiffening structure, which is arranged in the area of the spaces between the fingers.

  • the fingers can have any shape and are preferably designed in the form of a circular cone or a circular truncated cone, ie they taper towards their outer free end.
  • the wearer has a handle portion or he can be attached to a corresponding handle portion on which a user can grasp the brush and hold it during handling.

  • a corresponding brush is made by first the stiffening sleeve is made, in which then the soft plastic is introduced under pressure. The plastic penetrates the sleeve at the through holes, thus forming outwardly projecting fingers. In this way, each finger is surrounded in its foot by the stiffening sleeve and supported on all sides.
  • the mascara When a liquid or pasty medium, for example mascara, is to be applied with the brush, the mascara is in a storage container which has an insertion opening through which the brush is placed in the storage space. container can be introduced. The insertion opening is covered by a flexible, flap-like scraper, which is intended to strip an excessive amount of adherent mascara during withdrawal of the brush from the storage container.
  • the brush After removing the brush from the reservoir, the brush is brought into contact with the eyelashes in combing motion in a known manner, wherein the mascara is transferred to the eyelashes and at the same time the eyelashes are also combed.
  • the fingers of the brush In order to achieve a good combing effect and to ensure sufficient transfer of the mascara to the eyelashes, the fingers of the brush must have sufficient flexural rigidity, i. they must not dodge excessively during the combing and application movement. However, the necessary bending stiffness of the fingers is so high that the extraction of the brush from the reservoir and the resulting stripping excess mascara is difficult. If the fingers are formed to solve this problem with a low bending stiffness, although the brush can be easily inserted into the reservoir and pulled out of this, but a good order of mascara on the eyelashes is no longer given because the fingers too light dodge.
  • the brush it is advantageous if this has at least in the area of the finger or bristle trim increased resilience, that is, when the brush at loads that occur perpendicular to its longitudinal extent, can deform sufficiently to contact with an irregularly curved Surface, for example, in the oral cavity of a patient, an adaptation of the brush shape to the contours of the surface is possible.

  • the invention is based on the basic idea of forming the stiffening structure not in the form of a tubular sleeve but only in the form of a plurality of longitudinal ribs extending in the longitudinal direction of the rod-shaped carrier and thus of the brush.
  • the longitudinal ribs have a substantially lower flexural rigidity than the closed tubular sleeve, so that the brush has an increased deformability, especially in the region of its bristle or finger trimming, for radial loads, that is to say perpendicular to its longitudinal extension. In this way, the brush conforms in shape to the surface with which the brush is brought into contact.
  • the longitudinal ribs have the further advantage that the fingers in their foot region are not completely surrounded by the stiffening structure, but that the longitudinal ribs only on two opposite sides, ie on the transverse to the longitudinal direction of the brush and thus in the circumferential direction facing sides are supported by the longitudinal ribs, while in the foot area of the fingers on the two sides pointing in the longitudinal direction of the brush sides no support is given.
  • This has the consequence that the fingers have lower stability and thus greater deformability for loads which extend in the longitudinal direction of the brush than for loads which occur perpendicular thereto, ie transversely to the longitudinal extent of the brush or in its circumferential direction.
  • the fingers are relatively strongly deformed in the longitudinal direction of the rod-shaped carrier, since they have a lower bending stiffness in this direction.
  • the insertion of the brush into the reservoir and the withdrawal is made easier.
