Definitions

  • the invention relates to a method for producing Bristles for applying media by adding bristles cut-to-length filament extruded and with recesses for Recording of the medium is provided, from which the medium if the bristles are used as intended.
  • the invention further relates to those produced by this method Bristles and bristles with such bristles.
  • Bristle goods with bristles for applying media in Above all, liquid, viscous or powdery form in the field of body, hair and oral care, but also in the household and in the technical area of application. below the invention is primarily in connection with Toothbrushes as one of the essential application examples described.
  • the hollow bristle may also be radial Walls braced so that they are three or four axially parallel Has chambers.
  • the desired media are in introduced in liquid form. To this end become filaments with the cross-sectional shape of the finished bristle extruded and multiple filaments into multi-strand strands up to 5.5 cm in diameter and up to a length 1.2 m combined. The strand will end with one dipped in the liquid medium and on the opposite open ends of the filaments created negative pressure.
  • a polymer article is known from US Pat. No. 4,775,585 known in the form of a fiber which has a full cross section, a medium in partial areas of the cross section is introduced, which is released from the fiber in use shall be.
  • the subareas of the medium contained in the Fiber can either be circular sectors over the circumference be distributed or an outer ring of cross section form. A defined delivery of the medium is based on this Way not to achieve.
  • the invention has for its object a method propose using the media of any consistency and any Effect in an economical way in a bristle introduced and when used as intended in the desired Dosage during the life of the bristle can be delivered.
  • the media of made on the outside in the recesses open to the outside do not have to go through a pressure drop alone over a greater distance with corresponding pressure losses be sucked in.
  • the recesses can in particular can also be filled with a constant media density.
  • the consistency of the media also plays a role in the contribution no significant role; they can be liquid, viscous or be dispersed.
  • the delivery in use takes place immediately through the circumferential gaps or openings by this are so narrow that the medium is held back and can only emerge when used, for example by the forces occurring when brushing or by am Use existing media that match the medium in the Bristles interact and wash them out or detach.
  • the come Saliva or a dentifrice the simplest for cleaning brushes Fall water or moisture in question.
  • the filament with a mechanical Properties of the bristle with extruding core extruded will, the recesses spaced from the center of the core molded in and opening to the circumference of the filament and be filled with the medium from the outside, and that then on the filament at least in some areas layer at least partially covering the recesses is applied, which the release of the medium under the when the bristle is used as intended Controls conditions.
  • this procedure there is less crucial to the shape of the circumferential opening and on the opening width. Rather, by choosing the material of the layer, its thickness and the Extent of coverage of the recesses containing the medium the delivery of the medium in time and depending on the service life of those equipped with such bristles Bristle goods can be controlled.
  • the medium can be opened Bristle end or by the slow wear of the Jacket exposed openings of the recesses or are released by diffusion through the jacket, whereby the coat in contrast to the bristle according to WO 98/24341 can be comparatively thin-walled, since it is filled is not exposed to compressive forces.

  • the recesses are located away from the center of the core molded outward extending capillary gaps be or that the recesses as channels with circumferential openings narrowed into a gap.
  • the capillary-like gaps result in a retention effect for the medium and this is only among the Use prevailing conditions, e.g. B. by brush pressure, delivered by external media or the like.
  • the shape and / or the width of the column matched to the consistency of the medium. It is also of advantage if the gaps are molded so that they are completely closed in the unloaded state and only open under pressure.
  • the recesses that are open to the outside can be particularly economically in a continuous process on one Fill continuous filament. This can be done in that the filament through a media bath, if necessary under Pressure is set, or by a nozzle-like narrowing Cross section with the medium supplied on the circumference is passed through. Is the opening width of the recesses large enough and the consistency of the medium sufficient Filling can also be viscous without pressure using the continuous process happen. In this case it is recommended to make the recesses then by one applied to the filament Close coat.
  • the jacket is preferably made of a thermoplastic Plastic on the filament filled with the medium is extruded. It is preferably extruded in excess and shrink-wrapped onto the filament, which is particularly gentle on thermally sensitive media stay; liquid components cannot evaporate and thermally reactive components do not decompose. Becomes a jacket, as mentioned above, made of one that is permeable to the medium Applied plastic, he can if necessary partially by a diffusion-proof material to be covered locally and / or the rate of diffusion to control.
  • the coat is made of a transparent plastic, can media consumption, for example through appropriate Coloring of the media, optically controlled, if necessary the type of media can also be visualized.
  • an effect indicator for the Bristle function may be provided to ensure that the bristle is only used as long as it is used for the has the required properties as intended, or to design the bristle technically so that it is no longer used as practicable. This can be done happen that a jacket made of a thermoplastic Plastic with fillers that determine its wear factor is applied to the filament, the plastic and the fillers added to the permissible Degree of wear of the bristle when used as intended be coordinated. With this procedure you can also any other bristles that may only be made consist of a core and a jacket, with an effective indicator equip.
  • the wear factor solid articles are particularly suitable, which the Reduce intermolecular bond in the polymer of the jacket and control the wear factor by type, size and quantity.
  • the solids can be selected so that they are at the same time in the application perform a function, e.g. B. calcium carbonate or chloride as reminalizing agents in toothbrushes.
  • the addition of waxes, especially ionomer wax also has proved to be favorable, since these are in the polymer matrix distribute more evenly and thus for a more even Cause wear factor. This also makes the gliding behavior the bristle is influenced favorably. That is at the same time a fine adjustment of an effective indication is also possible.
  • different media with different functions can also be layered in the recesses or housed separately locally and correspondingly dispensed locally separately.
  • components of an active ingredient that are affine to one another and are only supposed to develop their effect on site, for example, can be accommodated locally separately.
  • An example is the desired formation or regression of calcium fluoride layers on the teeth, which can be formed in the ionizing medium from Ca (+) and F (-) ions, which in turn are made up of locally separated Ca and F compounds in the humid atmosphere of the mouth and throat can be generated.
