Definitions

  • the invention relates to a carrier body for a bristle insert, a brush which has such a carrier body and a bristle insert, and a method for producing such a brush.
  • the brush is a filigree brush such as a cosmetic brush, mascara brush or interdental brush, which has in common that they have a bristle insert, the load-bearing structure of which consists of a wire that is bent through 180 ° in the middle and whose two sections are twisted together, wherein a plurality of bristles are clamped between the two twisted sections along part of the wire.
  • the part of the wire provided with the bristles forms a bristle section, and a part not provided with bristles forms an anchoring section which is fastened on or in the carrier body.
  • the disadvantage of this method is a very low cycle rate, since it is necessary for the carrier body with the bristle inserts embedded therein to remain in the injection mold for a certain time until the injected injection molding material has solidified sufficiently. Even when using a multiple injection mold that has a plurality of cavities, the clock rate is lower than the clock rate at which bristle inserts can be made. It is therefore necessary to temporarily store the bristle inserts produced before they can be connected to the carrier body. Alternatively, the tool that produces the bristle insert is operated at a lower speed than is theoretically possible.
  • the anchoring section is heated and pressed into the material of the carrier body in order to be anchored there after it and the material which it has heated have cooled again.
  • the disadvantage of this Method also has a very limited clock rate, as it takes some time to warm up the anchoring section and then let it cool down again.
  • Another method is to provide a receptacle bushing for the anchoring section in the carrier body, to heat the material of the receptacle bushing to a softening temperature and then to compress the bushing from two sides after the anchoring section has been inserted into the receptacle bushing.
  • This method high clock rates can be achieved.
  • the object of the invention is to provide a brush of the type cosmetic brush, mascara brush, interdental brush or the like, which can be produced at a high cycle rate and in which the bristle insert is reliably anchored to the carrier body.
  • the object of the invention is also to create a method for producing such a brush.
  • a support body for a bristle insert is provided according to the invention, the bristle insert being formed from two wire sections twisted together, the support body having a guide opening whose cross section is larger than the cross section of the twisted wire of the bristle insert to be attached to the support body, and an embedding surface , which is accessible in a direction lateral to the longitudinal direction of the guide opening, in particular perpendicular to the guide opening.
  • a brush with such a T carrier body and a bristle insert which fastens in the T carrier body wherein the bristle insert has two wire sections twisted together, which clamp a plurality of bristles between them in a bristle section and form an anchoring section in a section free of bristles, which is received in the carrier body and fastened there, characterized in that the anchoring section has a bending section has, in which it extends in at least one direction deviating from the longitudinal direction, and that the anchoring section is embedded in the material of the carrier body such that more than 50% of the cross section of the anchoring section is below the level of the embedding surface.
  • the anchoring section of the bristle insert is inserted through the guide opening of the carrier body until it lies opposite the embedding surface.
  • a sonotrode is then activated and pressed onto the anchoring section, so that the material of the carrier body is melted locally and the anchoring section is pressed into the carrier body by the sonotrode, the anchoring section being plastically deformed by the sonotrode to form the bending section.
  • the invention is based on the basic concept of melting the anchoring section into the carrier body by means of so-called ultrasound embedding and plastically deforming the anchoring section in such a way that it no longer has a straight course.
  • “Melting” means that the material of the carrier body in the region of the Contact with the anchoring area of the bristle insert locally softens and / or melts (due to the vibrational energy coupled in by the sonotrode) and the anchoring section is pressed so deep into the material of the carrier body that its widest dimension in cross-section (assuming an idealized circular cross-section) the "equator" of the cross-section) is below the level of the embedding area and the cross-section is preferably completely below the level of the embedding area.
  • An embedding area is characterized by the fact that it is present on the carrier body before the bristle insert is attached (that is, it is not first molded in subsequently injected material), and that it is plastically deformed by the anchoring area so that it is molded into the material of the Carrier body is embedded (and is not only slightly deformed locally as a result of mechanical pressure exerted by the anchoring area on a surface of the carrier body).
  • an anti-twist protection is formed, which ensures that the wire can no longer be “unscrewed” from the carrier body.
  • the remaining, undeformed part of the anchoring section then forms a pull-out protection. Since a large part of the cross section or even the entire cross section of the anchoring section is embedded in the support body, overall high holding forces result.
  • the embedding surface can be flat, and the bending section of the anchoring section can be designed as a concave “dent” which is pressed into the material of the carrier body by the sonotrode.
  • the sonotrode preferably has a projection which locally deforms the anchoring section into a bending section which is embedded in the material of the carrier body.
  • the embedding surface has a concave depression.
  • the anchoring section is deformed into this recess by the sonotrode when it is pressed onto the anchoring section.
  • the embedding surface has at least one section that extends obliquely to the longitudinal direction of the guide opening, in particular in such a way that the embedding surface is offset from the guide opening.
  • the bending section of the anchoring section is produced in this embodiment in that the anchoring section as a whole is displaced by more than the embedment depth relative to the plane in which it is guided by the guide opening.
  • the anchoring section is preferably displaced relative to the position which is predetermined by the guide opening by a path which is more than 200% of the diameter of the anchoring section.
  • the embedding surface is the bottom of a narrow slot.
  • the side walls of the slot guide the anchoring section, so that the sonotrode can be reliably pressed through the slot onto the anchoring section, even if the sonotrode has a very small width.
  • the slot can extend in the same direction as the guide opening. This makes it easier to insert the anchoring section into the slot and onto the embedding surface.
  • the slot is curved.
  • the anchoring section is deformed in relation to its straight starting shape before it is pressed into the embedding area by the sonotrode. Due to the curved course of the anchoring section, it is no longer necessary to deform it locally in order to obtain the desired protection against unscrewing.
  • the slot preferably has a width of less than 2 mm, particularly preferably less than 1 mm. With this small width, it is not absolutely necessary to close the slot afterwards, since the narrow slot does not impair the usability of the brush.
  • the embedding surface is the bottom of a shaft. This enables a wider sonotrode to be used to press the anchoring section into the embedding area. If necessary, a closure part must then be attached in order to seal the carrier body from the outside.
  • the embedding area is arranged below a plurality of access openings which are separate from one another.
  • the embedding area is not or almost not visible from the outside; the access openings can be made so small that they are perceived as part of the design.
  • Polypropylene is particularly suitable as the material for the carrier body, since it can be injection molded very well and enables it to be melted by the energy introduced by the sonotrode.
  • the guide opening preferably has a circular cross section, so that the anchoring section of the bristle insert can be guided reliably.
  • the guide opening could also be designed as a slot, which laterally guides the anchoring section in such a way that it comes to lie at the desired location on the embedding surface.
  • a closed guide opening there is the advantage that the guide section keeps all loads away from the anchoring section which attempt to pull the anchoring section “upward” from the embedding surface.
  • the guide opening is designed as a slot, precautions are preferably taken to prevent peeling forces from acting on the anchoring section 14.
  • the slot should either extend in a direction that prevents the anchoring section from being pulled out of the embedding area (for example parallel to the embedding area), or the slot is subsequently closed with a cover or the like, so that there is a closed guide opening .
  • the cross section of the guide opening is preferably at the cross section of the Anchoring section adapted; the guide opening has a slightly larger cross section.

  • the bristle insert 10 consists of a piece of wire which is bent in the middle, so that two sections of equal length are obtained. These are twisted together. A large number of bristles are introduced in one area between the two wire sections twisted together, so that the bristles are clamped between the wire sections. The bristles form a bristle section 12. Outside the bristle section 12, the twisted wire sections are free of bristles.

  • the sonotrode 60 is activated in such a way that it transmits ultrasonic vibrations to the anchoring section 14. Due to the friction with the material of the carrier body 20, these lead to the material being heated and softened (and at least partially also melted).

Since it is much deeper than it is wide, the anchoring section 14 at the bottom of the slot cannot be seen or can hardly be seen.
