Definitions

  • the invention relates to a brush with a brush body and held on a bristle carrier bristle bundles and to a method for their preparation.
  • the bristle bundles can adapt more flexibly to the surface treated with the brush and / or in the simple production of different brushes is possible.
  • the achievement of this object is that between the brush body and the bristle carrier an intermediate layer of an additional material component is provided and that the bristle carrier forms an intermediate layer and the bristle bundles at a distance holding separating layer.
  • the additional material component thus does not come in contact with the bristle bundles during injection, as a result of which overspraying in the bristle area is reliably avoided.
  • the fastening-side ends of the bristle bundles can also be melted in and the individual bristle filaments of a bundle of bristles can be connected to one another.
  • the intermediate layer consists of elastic material.
  • the bristle carrier with the bristle bundles elastic, practically “floating", attached to the brush body and thus, in the case of a toothbrush brushing teeth, Dodge and adapt to the teeth, which allows a more thorough and gentle cleaning.
  • a kind of suspension is formed for the bristle bundles thus a kind of suspension is formed.
  • bristle carrier has grooves, depressions or the like material weakenings between adjacent bundles of bristles or if the bristle carrier has sleeves for receiving the individual bristle bundles, which are connected to one another via thin-walled webs or similar material bridges. The thinner the bristle carrier itself is formed, the higher its flexibility in itself.
  • bristle carriers are provided on a brush body. Several bristle carriers can thus be combined to form a larger total bristle field, whereby different combinations of different bristle carriers are possible in order to easily produce different brushes.
  • the intermediate layer protrudes in the transverse direction to the longitudinal direction of the bristle at least in sections over the outer circumference of the brush body and / or the bristle carrier. This results in a completely or partially around the brush head circumferential pad, which can be used as protection or as an additional functional element, for example, for tongue cleaning.
  • additional functional elements of the additional material component which are connected to the intermediate layer. These can then be produced in an injection process with the intermediate layer.
  • massage knobs a tongue scraper or a mucous membrane protection may be provided as additional functional elements be.
  • lamellar knobs arranged parallel to them can protrude, with which the gums can be massaged when brushing the teeth.
  • the intermediate layer with the brush body and the bristle carrier may each be connected materially.
  • the intermediate layer can also serve as a link to combine two different materials for the brush body and the bristle carrier, which can not be directly connected to each other.
  • the intermediate layer is welded or adhesively bonded to the brush body and the bristle carrier in each case.
  • bristle carrier and / or the brush body serve as spacers in the manufacture of the brush.
  • One element bristle carrier or brush body
  • This ensures a defined position with correct spacing between the two elements.
  • the support elements may be formed tapering. Depending on the degree of hardness of the support elements, the free ends are removed during assembly of bristle carrier and brush body or pressed into the other element. This causes on the one hand a good hold of the two elements to each other, which may be particularly advantageous if the elements were prefabricated and only after several days of storage, in which slight deformations may result, are connected to each other. On the other hand arises a tension that presses the brush body and the bristle carrier against the mold surfaces of the mold during injection of the additional material component, thereby ensuring precise positioning of the elements.
  • the free ends of the support elements of the bristle carrier in each case engage in a receptacle of the brush body and / or the free ends of the support elements of the brush body in each case in a receptacle of the bristle carrier.
  • the high angular accelerations between brush body and bristle carrier can be transmitted better.
  • the receptacles of the bristle carrier and / or the brush body may each have an undercut and the free ends of the support elements each having a corresponding counter-profiling.
  • the bristle bundles can be connected in particular by molding their fused attachment ends with the bristle carrier, which is formed by the encapsulation. However, it is also possible that the bristle bundles are stuffed into a bundle receiving holes having bristle carrier with anchor loops or anchor plate. It is also conceivable gluing or welding the bristle bundles to a prefabricated bristle carrier.
  • the invention is characterized in that between the brush body and the bristle carrier an additional material component is introduced as a connecting means, and that the bristle carrier forms a separating layer holding the connecting means and the bristle bundles at a distance.
  • the brush body and the bristle carrier are held spaced from each other and the additional material component introduced into the space between the brush body and bristle carrier.
  • the additional material component which usually takes place in the injection molding in the heated state, this fills the gap and thereby forms a material connection between the brush body and bristle carrier.
  • This manufacturing method has the great advantage that both the brush body and the bristle carrier can be previously produced on separate injection molding machines and then the introduction of the additional material component is carried out on a third injection molding machine.
  • Each of these three injection molding machines can be made small and simple, so that the initial cost of a corresponding manufacturing device are low and cost-effective production is possible.
  • prefabricated brush body and bristle carrier can be connected to the third injection molding machine with the additional material component, so that with little effort a diverse brush assortment, for example, with brush bodies of different color and handle shape and bristle carriers can be made with differently shaped bristle field.
  • the bristle carrier can be overmolded with the additional material component, and then the bristle carrier provided with the additional material component with further material to form the brush body molded.
  • a further variant of the inventive method provides that the additional material component is applied to the brush body, that the bristle carrier is applied to the additional material component and that then the brush body and the bristle carrier are each connected to the additional material component.
  • the bonding of the brush body and the bristle carrier with the additional material component can be effected in particular by melting.
  • an intermediate layer 5 made of an additional, elastic material component is provided between the brush body 2 and the bristle carrier 4.
  • the bristle carrier 4 is not rigidly connected to the brush body 2, but stored practically “floating", so that the bristle bundles 3 in the use of here as a toothbrush trained brush 1 better and can adapt to the contour of the teeth, whereby a more thorough and gentler cleaning is possible.
  • the fastening-side ends of the bristle bundles 3 are each enclosed by the material of the bristle carrier 4, so that the bristle carrier 4 forms a separating layer which holds the intermediate layer 5 and the bristle bundles 3 at a distance.
  • the additional material component of the intermediate layer 5 thus does not come into contact with the bristle material or the fused holding region 6 of the bristle bundles 3, so that overmolding in the bristle region is avoided when injecting the additional material component of the intermediate layer 5 during the manufacture of the brush 1.
  • the intermediate layer 5 and the bristle carrier 4 are arranged in a trough-like depression of the brush body 2.
  • the elastic material component of the intermediate layer 5 is visible only as a border on the bristle field side, while the side surfaces of the brush body 2 are determined by its material.
  • the elastic material of the intermediate layer 5 extends to the edge of the brush body 2 and the bristle carrier 4, so that the elastic material of the intermediate layer 5 is laterally visible.
  • the bristle carrier 4 can be stronger than in the brush according to FIG. 1 Dodge laterally and move relative to the brush body 2, so that the bristle bundles 3 can even more adapted to the teeth or the surface to be cleaned.
  • the elastic material of the intermediate layer 5 laterally over the bristle carrier 4 and at the free end of the brush body 2 via this over.
  • the intermediate layer 5 thus additionally forms a cushion with which the brush 1 can be protected against damage.
  • the brush body 2 has a plurality of support elements 7, which each engage with their free end in a receptacle 8 of the bristle carrier 4, and thus brush body 2 and bristle carrier 4 are likewise mounted at a defined distance from each other.
  • a better power transmission between the brush body 2 and bristle carrier 4 is given by the intervention of the support elements 7 in the receptacles 8, which is particularly important for oscillating brush heads rotating electric toothbrushes.
  • additional material component is in the brush 1 according to FIG. 5 not only the intermediate layer 5 injected, but also additional functional elements in the form of a in the bristle field above Massagenoppe 9a and a tongue scraper 9b on the back of the brush body 2.
  • the additional functional elements are connected to the intermediate layer 5 so that they in a common injection process in a can be generated according to trained injection mold.
  • the brush 1 according to FIG. 6 also has additional functional elements in the form of a tongue scraper 9b and a mucous membrane protection 9c. The latter is intended to prevent injuries in the mouth during cleaning.
  • a tongue scraper 9b and a mucous membrane protection 9c At the brush 1 according to FIG. 6 are provided on the brush body 2 support elements 7, on which the bristle carrier 4 rests and so, similar to the brush 1 from FIG. 4 in which support elements 7 are provided on the bristle carrier 4, a defined distance between brush body 2 and bristle carrier 4 for spraying the intermediate layer 5 is formed.
  • the brushes 1 can each be produced by the bristle carrier 4 carrying the bristle bundles 3 is inserted into an injection molding machine and there first, the additional material component for the intermediate layer 5 and then further material for the formation of the brush body 2 is molded.
  • This manufacturing method has the advantage that in each case simple injection molding machines for the individual components can be used in different versions, which enables their production cost-effective, which can then be combined with each other arbitrarily.
  • brush body of different shape and color can be combined with bristle carriers, which in turn have bristle bundles in a different arrangement and / or profiling.
  • bristle carriers which in turn have bristle bundles in a different arrangement and / or profiling.
