Definitions
- the invention relates to a brush, in particular a toothbrush, with a brush body and at least one bundle of flexible bristles.
- the invention further relates to a method for producing such brushes.
- stiffer bristles could be used, it being possible to increase the rigidity by appropriately selected bristle material or by a larger diameter of the individual bristles.
- the user therefore tends to increase the contact pressure on the brush when cleaning interdental spaces.
- the invention is therefore based on the object of improving the stability of the bristle bundles in the case of a brush of the type mentioned at the outset, so as to enable longer use with a sufficiently high degree of flexibility of the bristles or bristle bundle, and to specify a method for their production.
- This object is achieved with a brush of the type mentioned at the outset that at least one support element is provided on the brush body for lateral support of at least one bundle of bristles. Furthermore, this object is achieved by a method in which the brush body and the respective support elements are produced in a two-component injection molding process.
- the side support prevents the outer bristles from evading from the originally intended position, at least in the area of the support, due to wear, so that, compared to a brush with the same degree of wear, but without any support, there is less spreading at the end of use of the bristle bundle, and thus a longer service life of the brush is made possible.
- the solution according to the invention therefore makes it possible to use softer bristles or bristle bundles than previously.
- thinner bristles or softer bristle materials, or a combination of both can now be used.
- This enables a gentler and, above all, much more thorough brushing of the teeth and reduces the risk of injuries to the oral cavity, and in particular to the gums.
- the clearly perceptible deformation of the bristles during cleaning also reduces the contact pressure when cleaning, as too much pressure is ke deformation of the bristle bundle involuntarily recognized by the user as incorrect and will be corrected immediately.
- the brush according to the invention thus supports a medically correct brushing of the teeth.
- more effective cleaning is achieved, since the number of bristles per bundle can be increased by using thinner bristles and thus more bristle ends are effectively engaged.
- the side support of the bristle bundles is preferably elastic.
- the invention can be used both for brushes with a bristle bundle and for brushes with a large number of bristle bundles.
- the use of the brush according to the invention is not restricted to the dental field or the cosmetic field. Rather, such brushes can be used in all areas of daily life and technology, preferably where particularly gentle cleaning of relief-like surface formations is required and / or a particularly long service life of the bristles is desired.
- a separate support element is preferably provided for each bristle bundle. This allows the bending characteristic of individual bristle bundles to be set individually with a corresponding selection of the support element with regard to its shape and its deformability. For example, on a toothbrush with several rows of bristles, the outermost bristle bundles or the front bristle bundles can be supported by supporting elements of higher rigidity than the remaining ones. It is also conceivable to support only a part of the bristle bundles by means of supporting elements, but to leave the remaining ones unsupported.
- a plurality or all of the support elements are integrally connected to one another and attached to the brush body as a support unit.
- the integral design enables the support elements to be manufactured more easily if these are produced using an injection molding process.
- the support element preferably has an elastic sleeve section, in which a bristle receiving opening extends, and a base section, via which the sleeve section is connected to the brush body.
- an elastic sleeve section in which a bristle receiving opening extends
- a base section via which the sleeve section is connected to the brush body.
- the shaping of sleeve-like support elements enables a more precise setting of direction-dependent deformation properties of the respective support element and a higher degree of deformation.
- the contact area between the brush body and the support element can be increased in order to prevent loosening of the support element even better.
- the bristle bundles are preferably fastened in the bristle body, the individual bristle bundles extending through the respective support elements.
- the bristle bundles can also be fastened only in the support elements, with composite adhesion being achieved between the bristle bundles and the support elements.
- the sleeve section or its outer contour can be essentially cylindrical.
- the person skilled in the art will apply the required bevels and curvatures for easier removal from the mold.
- the sleeve section can also be designed such that its wall thickness tapers towards the end of use of the bristles.
- the bending characteristic of the Systems bristle bundle / support element can be influenced in the desired manner.
- the shape of the outer sleeve can be adapted to the requirements of a desired bending line of the bristle bundle or individual bristles.
- the support elements are connected to one another via their base sections to form an integral support element.
- the brush body can be completely covered on the bristle side by the integral support element, which leads to a homogeneous appearance and a high detachability of the support elements.
- an integral support element can be produced in a particularly efficient manner.
- a surface formation for increasing the contact area between the two can be provided between the brush body and the respective base section of the support element in order to improve the resistance to detachment.
- a corresponding increase in surface area can be achieved, for example, by corrugation on one or both parts.
- the application of grooves, ribs, hole patterns or the like can be cited as further examples for increasing the contact area.
- the support element is designed such that it can be produced as an injection molded part. This can be cast or sprayed directly onto the brush body. The bristles are done in a conventional manner.
- One possibility is to fold a bundle of bristles and then fix the folded end in the brush body using an anchor.
- the armature for example a plate-shaped metal or plastic part, with the bristle bundle wrapped around it can be inserted, for example stamped, into an opening provided on the brush body.
- the bristles can also be made by melting the ends of the bristle bundles to be fastened so that thickenings form. The thickenings are then extrusion-coated with brush body material or with support element material, so that the bristle bundles are held in a form-fitting manner.
- the brush can be produced in a two-component injection molding process, wherein the brush body consists of a hard plastic component and the support elements as bristle edging preferably consist of a soft plastic component, for example a thermoplastic elastomer, but can also be made of a hard component. Ideally, composite adhesion is realized between the hard component of the brush body and the support element or the support elements. With appropriate material management, the brush body and support elements can be produced in successive manufacturing steps in a single mold.
- Fig. 8 a further embodiment according to the invention, in which the bristle bundles are each fastened with a melted end in the brush body.
- FIGS. 2a to c A first exemplary embodiment will now be explained below with reference to FIGS. 2a to c, reference being made to a toothbrush with a multiplicity of bristle bundles, as shown in FIG.
- a brush body 10 which can be formed in one piece with the handle of the brush is provided with a large number of blind holes 11 which can be produced in any manner.
- Each of the blind holes 11 serves to receive a bundle of bristles 20, which consists of a plurality of, preferably thin, flexible bristles, which are made of plastic.
- This bristle bundle 20 is folded or looped around an anchor 40, so that all bristle ends point in one direction.
- Each bundle of bristles is clamped in its blind hole 11 by the armature 40 clawed in the brush body 11.
- the armature is designed as a flat plate which is punched upright in the brush body 10 with respect to the blind hole 11.
- a support element 30 is attached to the bristle side of the brush body for each bristle bundle 20.
- the embodiment of the support element 30 shown in FIGS. 2a to 2c has a bristle receiving opening 31 for lateral support of the bristle bundle 20.
- the bristle bundles are preferably supported up to approximately half their length.
- the support element 30 has a sleeve section 32 that is elastically deformable in particular in the radial direction and a base section 33 that extends in the radial direction beyond the sleeve section 32 in the manner of a flange.
- the respective support element 30 is connected to the brush body 10 via this base section 33.
- the bristle receiving opening 31 extends through the sleeve section 32 and the base section 33.
- a surface formation for increasing the contact area between the two is preferably provided between the support element 30 or its base section 33 and the brush body 10 in order to further improve the resistance to detachment of the respective support element. This can take place, for example, by corrugation or the provision of grooves, ribs, hole patterns or the like on one or both contact surfaces. Bonding adhesion can be achieved between the support elements 30 or their base sections 33 and the brush body with a suitable choice of material and suitable manufacturing parameters.
- the individual support elements are connected to one another by their base sections 33 to form an integral support element and completely cover the brush body on the bristle side in the region of the bristles.
- the sleeve section 32 is essentially cylindrical, so that the bristle bundle has the same bending behavior in all directions.
- the bristle receiving opening 31 can influence the bending behavior of the bristle bundle / support element system in the desired manner and as required.
- An eccentric arrangement of the bristle bundle in the sleeve section 32, as shown in the bristle bundles shown on the right in FIG the most stressed bristles is further improved.
- a partial lateral support can be provided through the bristle receiving opening 31, as is shown in the right bristle bundle in FIG.
- FIG. 3 Another embodiment of the support element 30 is shown in FIG.
- This support element differs from the shape shown in FIG. 2a primarily by its essentially frustoconical design.
- the bending behavior of the bristle bundle / support element system can be made even more homogeneous than in the previously described exemplary embodiment. In particular, this can further reduce the load on the individual bristles in the exit region from the support element 30.
- the conical configuration in the transition area of the sleeve section 32 to the base section 33 results in a lower notch effect, so that the stability of the support element 30 is further improved.
- a separate support element 30, which is separate from the support elements of the other bristle bundles, can also be provided for each bristle bundle.
- FIG. 4 A further embodiment of the support elements 30 is shown in FIG. 4, which are formed integrally with a solid material body. This results from the outside the impression of a conventional brush, which, however, has the advantages of the preferably elastic side support of the bristle bundles 20 already described. As shown by way of example in the case of the bristle bundle on the right in FIG. 4, this can also only be partially supported laterally in order to achieve a direction-dependent bending characteristic.
- the support elements 30 are attached to the brush body 10, which is already provided with blind holes 11 and is preferably injection molded from a hard plastic component, for example by injection molding or else by an adhesive process or a similar process, so that a deeper blind hole is formed.
- a two-component injection molding process is preferably used for this purpose.
- FIGS. 7 and 8 Two further embodiments of the invention are shown in FIGS. 7 and 8.
- the bristle bundle 20 has at its end to be anchored a thickened portion of fused bristle material, which ensures sufficient bundle extraction force.
- the bristle bundle 20 is accommodated in the bristle receiving opening 31 of the respective support element 30, and thus the bristle bundles are fastened in the support elements.
- the bristle material and the support element material are selected so that bond adhesion is achieved.
- the bristle bundles 20 are melted at their end to be anchored in the support element 30, so that mushroom-shaped thickenings 25 form.
- the thickenings are then encapsulated with support element material which encloses the thickenings.
- the support elements are then connected to the brush body, which can be injection molded onto the support element or elements, for example.
- the thickened ends of the bristle bundles 20 are fastened in the brush body 10.
- the individual bristle bundles 20 are introduced into prefabricated support elements 30, so that the thickenings 25 of the individual bristle bundles 20 protrude from the support elements 30.
- the thickenings are then encapsulated with a hard plastic component that forms the brush body 10.
- the bristle bundles are formed by a large number of thin plastic bristles.
- the invention is not limited to plastic bristles. Rather, bristles made from natural fibers can also be used.
- the brush body 10 can also be produced from a material other than plastic, for example wood or metal. However, all parts of the brush can preferably be produced as plastic injection molded parts.
- the elastic side support of the bristle bundles 20 by the support elements 30 can also be provided by a hard plastic component (material), the elasticity of which is achieved by the shape of the individual support elements 30. However, plastic soft components that have a Shore A hardness of less than 70 are preferably used for this.
- two-component process is not limited to the use of different materials, but also includes the possibility of using the same material with a different color, for example.
