Definitions
- the invention relates to a bristle for a toothbrush, in particular for an electric toothbrush, which is made from a monofilament made of plastic.
- the invention also relates to a method for producing a bristle for a toothbrush, in particular for an electric toothbrush, in which a monofilament is produced from plastic.
- Such a bristle and also such a method are known from German laid-open specification DE 196 45 852 A1.
- a monofilament is described there which has a non-circular cross section. After extrusion, the monofilament is twisted around its longitudinal axis and fixed with the help of chemical agents. This creates a three-dimensionally structured surface with which an improved cleaning effect is achieved, in particular when removing plaque.
- a bristle for a toothbrush which is made of plastic and has a plurality of filaments connected to one another.
- the filaments are wound or braided and bonded together using chemical means.
- fanning is achieved, for example, by subjecting the free end of the bristle to mechanical processing.
- the object of the invention is to provide a bristle made of a monofilament, in which a splitting of the free end of the bristle can be achieved in a simple manner.
- this object is achieved by the invention in that the bristle has at least two regions and at least one predetermined breaking point in cross section.
- the object is achieved by the invention in that the monofilament is produced in such a way that it has at least two regions and at least one predetermined breaking point in cross section.
- One or more predetermined breaking points are formed within the monofilament by the areas according to the invention which are present in the cross section of the monofilament and are preferably filled with plastic. These predetermined breaking points are located approximately where the at least two areas adjoin one another. If a bristle made from such a monofilament is to be spliced on at its free end, it is no longer necessary to use expensive cutting tools or the like. Instead, it is sufficient to mechanically machine the free end of the bristle. Such mechanical processing can be carried out, for example, by upsetting, tapping, rounding, cutting, grinding, polishing, beating or the like of the free end of the bristle.
- the thickness of the bristles can be between 0.1 mm and 0.25 mm, preferably between 0.15 mm and 0.18 mm.
- the cross section of the bristle can essentially take the form of a three or more-leaf clover or star.
- the outer surface of the monofilament can advantageously have a screw-like structure.
- the free end of the bristle no longer has to be machined with expensive cutting tools or the like. Instead, it is sufficient to mechanically process the free end of the bristle in order to cause the free end to be fanned out. With the help of this splice, an increased cleaning effect of the bristle is achieved, especially in the interdental area, or the surface polishing effect in combination with grinding particles of toothpaste improved.
- the mechanical processing for fanning out can be carried out by means of the rounding process of the free bristle ends, which is required anyway, which saves an additional working step, for example cutting the bristles.
- the bristle can be produced in a simple manner from a monofilament, it being possible in a simple manner to open the free end of the bristle.
- the areas are made of different plastics and / or a plastic and a cavity. This is achieved in that the areas are produced from the different plastics or with cavities or hollow channels during the extrusion of the monofilament.
- the areas are made from different fillers and / or from different colors.
- the predetermined breaking points occur at the transitions or interfaces between the areas, the different plastics or cavities or between the different fillers and / or the different colors.
- the free end of the bristle can be fanned out without great effort. It is also possible to impart certain properties to the monofilament by using the different plastics. In this way, an improved cleaning effect of the bristle not only can be achieved by fanning out the free end of the resulting bristle, but also by Possibility to imprint certain properties of the bristle through the use of different plastics.
- the regions are produced by dividing and then recombining the mass flow during the extrusion of the monofilament. This is achieved in that during the extrusion of the monofilament, the mass flow of the plastic is first divided into several strands in order to then be brought together again to form a common strand.
- the areas can consist of the same plastic, the predetermined breaking point being formed at the interface of the areas. The division and subsequent re-merging has the result that there is no intimate bond between the plastic of the different strands at those transitions at which the individual strands are brought together again. This can be achieved by a general intervention in the temperature control of the plastic or the extrusion tool.
- transitions represent predetermined breaking points, which - as already explained - can be converted into a splice-out by simple mechanical processing.
- this second embodiment it is thus possible by splitting and re-merging to splicing the bristle formed from the monofilament without great effort.
- the free end of the bristle is split open by rounding the free bristle end.
- the free end of the bristle is spliced or split open during the manufacturing step of rounding off this free end, which is already present as such.
- the invention thus saves the second manufacturing step.
- the monofilament for torsion is either drawn off from a rotating central spool, or it is pulled off from a standing central spool by means of a rotating nozzle.
- a particularly high speed at which the monofilament can be drawn off the spool In this way, the process for producing the monofilament is further accelerated.
- Figure 1 a shows a schematic representation of a cross section through a first
- Embodiment of a monofilament with two or more pairs of plastics one region being essentially star-shaped and the other regions being essentially in the manner of a circular segment or circular sector,

- regions 2, 3 are separated from one another by the area 4, it being possible for the plastic of the areas 2, 3 to have different fillers or colors.
- the region 4 can be designed in the form of webs arranged in a star shape, which are arranged essentially point-symmetrically and / or mirror-symmetrically to the central longitudinal axis of the monofilament 1.
- regions 2, 3 are designed in the form of a segment of a circle or a sector of a circle.
- the monofilament 5 of FIG. 1 b viewed in cross section, has successive regions 6, 7, which are each formed in the shape of a segment of a circle.
- the areas 6 of the monofilament 5 are filled, for example, with a first plastic, while the areas 7 are filled with the second of the two different plastics.
- all areas 6, 7 can also be formed by one and the same plastic, with a corresponding process control of the extrusion process ensuring a not too intimate bond at the interfaces of the adjacent areas 6, 7 by temporarily removing the extrusion compound during the extrusion several strands corresponding to areas 6, 7 are divided and then brought together again.
- the areas 6, 7 of the monofilament 5 form so-called predetermined breaking points at their adjoining transitions 8. These predetermined breaking points will be discussed in more detail in connection with FIG. 4.
- Polyamide or polyester is preferably used for the two plastics described.
- the combinations of PA 6.12 and polyester or PA 6.12 and PA 6 or PA 6.12 and polyester have been found to be advantageous.
- FIG. 2 a shows an extrusion tool 11 which is provided for producing a monofilament.
- the plastic provided for the production of the monofilament is passed as a mass flow in the direction of arrow 12 through the three successive parts 11 ', 11 ", 11'" of the extrusion tool 11.
- the mass flow of the plastic is divided into three strands. Then in the part 11 '" of the extrusion tool 11, the strands mentioned are brought together again to form a common strand. The monofilament emerges from the extrusion die 11 in the form of the last-mentioned common strand.
- 2 b shows the cross-sectional area of the mass flow or the strands of the produced monofilament resulting therefrom, as is the case on the respective parts 11 ', 11 ", 11'" of the extrusion tool 11.
- the monofilament still represents a uniform mass flow 13 with a uniform cross-sectional area.
- three independent strands 14 are formed there according to FIG. 2b Merging these strands 14 in the part 11 '"of the extrusion tool 11, these formerly independent strands again form a common strand 15, as shown in FIG. 2 b.
- This strand 15 is the monofilament emerging at the exit of the extrusion tool 11.
- Polyester or polyamide for example, is used as the plastic for the mass flow 13 of the monofilament.
- the mass flow 13 is divided into the individual strands 14 and thus into the regions 17 of the common strand 15 in such a way that the proportions of the regions 17 in the total area of the cross section of the common strand 15 are approximately the same size.
- 3a, 3b and 3c show further cross sections of monofilaments which are made of plastic. All of the monofilaments shown have a non-circular cross section. The monofilaments essentially have a star-shaped cross section, which has three or four points.
- a cavity 33 is provided in the interior of the monofilaments 31, 32 shown, which extends in the longitudinal direction of the monofilaments 31, 32.
- the cavity 33 essentially has a corresponding cross-sectional shape as the associated monofilament 31, 32.
- a plurality of cavities 34 are provided in the interior of the monofilaments 31, 32, which extend in the longitudinal direction.
- the cross-sectional shape of these multiple cavities 34 does not match the cross-sectional shape of the respective monofilament 31, 32.
- the cavities 33 can also be filled with a further plastic, so that areas bordering one another and corresponding narrowing or tapering are formed in one of the areas predetermined breaking points 35 by the phase boundaries.
- the monofilaments 31, 32 shown are provided with predetermined breaking points 35, which extend in the longitudinal direction.
- the predetermined breaking points 35 are generated by notching the wall forming the respective monofilament 31, 32 between the outer space and the cavity 33 from the outside. The thickness of the wall thus decreases at this point, which leads to an easier breakage of the monofilament 31, 32 at this point.
- the predetermined breaking point 35 described will be discussed in more detail in connection with FIG. 4.
- a monofilament 5 can be produced which has a plurality of regions 6, 7 in cross section, which are filled with different plastics.
- the extrusion tool 11 can be used to produce a monofilament 15 which consists of a single plastic but which also has a plurality of regions 17 when viewed in cross section.
- the bobbin 41 shown in FIG. 4 is set in rotation about its axis and the monofilament 42 is pulled off the bobbin in the direction of arrow 43.
- the bobbin 41 stands still and the monofilament 42 is unwound from the bobbin 41 with the aid of a rotating nozzle and drawn off in the direction of the arrow 43.
- the monofilament 42 is passed through a guide nozzle 44 and deflected by means of a deflection coil 45.
- the monofilament 42 can be drawn off the spool 41 in the direction of the arrow 43 at a very high speed.
- the monofilament 42 By rotating the monofilament 42 from the spool 41, the monofilament 42 is twisted about its longitudinal axis. After the deflection spool 45, the monofilament 42 is exposed to the action of chemical agents with which the monofilament 42 is fixed becomes. In particular, the torsion of the monofilament 42 is fixed or frozen by the chemical means.
- the same is cut and processed into individual bristles of approximately the same length.
- the bristles are then combined into tufts of bristles and fixed, for example, to a bristle carrier.
- the free ends of the individual bristles are rounded.
- the free ends are subjected to mechanical processing. For example, it is possible to round off all free ends of the bristles of a tuft of bristles by machining them with a grinding wheel. In this way it is achieved that the free ends of the individual bristles are no longer pointed, but rather round.
- the mechanical processing of the free ends of the individual bristles for rounding additionally has the result that when the monofilaments described are used, the free ends of the individual bristles are automatically spliced or split. Due to the mechanical processing of the free ends of the bristles, which is required to round the free ends, the free ends of the bristles break open at the predetermined breaking points of the monofilaments described. At the same time, this represents a splitting or splitting of the free ends of the bristles.
- the predetermined breaking points 8 of the monofilament 5 break open at the free ends of the respective bristle. A total of eight individual partial filaments are thus created at the free end of the bristle.
- the three regions 17 of the common strand 15 break open at the free end of the bristle. This creates three separate partial filaments at the free end of the bristle.
- these monofilaments break open in particular at the predetermined breaking points 35. This creates individual partial filaments at the free ends of the bristles.
- the mechanical processing of the bristle required for rounding the free ends of the bristle thus simultaneously splits the free ends of the bristles in their longitudinal direction.
- the splitting preferably extends over approximately 10% to approximately 25% of the length of the bristle.
- the bristles or tufts of bristles produced in this way are preferably used in an electric toothbrush.
- it is used in a round-head toothbrush, and is preferably provided there in the inner field.
