Definitions
- the invention relates to a method for producing bristles for applying media, in that a filament that can be cut to bristles is extruded and provided with recesses for receiving the medium, from which the medium is released when the bristles are used as intended. Furthermore, the invention relates to bristles and bristle articles produced by this method with such bristles.
- Bristle goods with bristles for applying media in liquid, viscous or powder-like form are used above all in the area of body, hair and mouth care, but also in the household and in the technical area.
- the invention is described below primarily in connection with toothbrushes as one of the essential application examples.
- WO 98/24341 it is also known (WO 98/24341) to accommodate therapeutically active media or other media with a dental medical effect in a hollow bristle, which are intended to be dispensed at the free open end of the bristle in use.
- the hollow bristle is optionally also stiffened by radial walls so that it has three or four axially parallel chambers.
- the required media are introduced in liquid form.
- filaments with the cross-sectional shape of the finished bristle are extruded and several filaments into multi-stranded strands with a diameter of up to 5.5 cm and a length of up to
- the filament is extruded with a core which also determines the mechanical properties of the bristle
- the recesses are formed at a distance from the center of the core and are opened to the circumference of the filament and are filled with the medium from the outside, the recesses are shaped with their circumferential opening in such a way that the medium is only released under the conditions prevailing when the bristle is used as intended.
- the media are introduced from the outside into the recesses which are open to the outside, and therefore do not have to be sucked in over a larger distance with corresponding pressure losses simply by means of a pressure drop.
- the recesses can thus in particular also be filled with a constant media density.
- the consistency of the media also plays no significant role in the contribution; they can be liquid, viscous or disperse.
- the dispensing during use takes place directly through the openings on the circumference, in that they are designed so narrow that the medium is retained and can only escape during use, for example by the forces occurring during brushing or by media present at the place of use, which are in contact with the medium in the Bristles interact and wash out or loosen them.
- the saliva or a dentifrice, with cleaning brushes in the simplest case water or moisture in question.
- the filament is extruded with a core which also determines the mechanical properties of the bristle
- the recesses are formed at a distance from the center of the core and are formed to open to the circumference of the filament and are filled with the medium from the outside
- a layer is at least partially applied to the filament, at least partially covering the recesses, which controls the delivery of the medium under the conditions prevailing when the bristle is used as intended.
- the dispensing of the medium can be controlled in time and in dependence on the period of use of the bristle goods equipped with such bristles.
- the medium can be dispensed through the open bristle end or through the openings of the recesses exposed during the slow wear of the jacket, or also by diffusion through the jacket, the jacket in contrast to the bristle according to WO 98/24341 can be comparatively thin-walled, since it is not exposed to compressive forces during filling.
- the recesses are preferred here essentially axially parallel, optionally formed at a distance from one another.
- recesses are formed after the filament has been extruded.
- An essentially radial shaping of recesses of any contour and arrangement is possible.
- the recesses are formed as capillary gaps extending outward from the center of the core or that the recesses are formed as channels with openings narrowed on the circumferential side to form a gap.
- the capillary-like gaps result in a retention effect for the medium and this is only under the conditions prevailing during use, eg. B. by brush pressure, by external media or the like. issued.
- the shape and / or the width of the column is preferably matched to the consistency of the medium. It is also advantageous if the gaps are molded in such a way that they are completely closed in the unloaded state and only open under pressure.
- the recesses that are open to the outside can be filled in a particularly economical manner in a continuous process on an endless filament. This can be done by passing the filament through a media bath, which may be pressurized, or through a nozzle-like narrowing cross section with the medium supplied on the circumference. If the opening width of the recesses is large enough and the consistency of the medium is sufficiently viscous, the filling can also be done without pressure in a continuous process. In this case it is advisable to then close by a coat applied to the filament.
- the sheath is preferably made of a thermoplastic which is extruded onto the filament filled with the medium. It is preferably extruded in excess and shrunk onto the filament by cooling, as a result of which thermally sensitive media in particular are preserved; liquid components cannot evaporate and thermally reactive components do not decompose. If, as mentioned above, a sheath is applied from a plastic that is open to diffusion for the medium, it can optionally be covered in regions by a diffusion-tight material in order to control the diffusion locally and / or the diffusion rate.
- the media consumption can be optically controlled, for example by correspondingly coloring the media, and the type of media can also be visualized if necessary.
- an action display for the bristle function can also be provided to ensure that the bristle is only used for as long as it has the properties required for the intended use, or the bristle technically so that it is no longer used as practicable.
- This can be done by applying a jacket made of a thermoplastic material with fillers that determine its wear factor to the filament, the plastic and the fillers added to it being matched to the permissible degree of wear of the bristle when used as intended.
- any other bristles which may only be made consist of a core and a jacket, provide with an effective indicator.
- Solid fillers which reduce the intermolecular bond in the polymer of the jacket and control the wear factor by type, size and quantity, are particularly suitable as fillers determining the wear factor.
- the solids can be selected so that they also fulfill a function in the application, for. B. calcium carbonate or chloride as reminalizing agents in toothbrushes.
- the addition of waxes, in particular ionomer wax, has also proven to be advantageous since these are distributed more evenly in the polymer matrix and thus ensure a uniform wear factor. This also has a favorable effect on the bristle's sliding behavior. This also makes it possible to fine-tune an effective display.
- 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 separately locally.
- 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 moist atmosphere of the mouth and throat can be generated.
- the media or active ingredient components can also be accommodated separately in the recesses in layers and can only be brought together when they are dispensed.
- the diffusion rate of the media or active ingredients can also be controlled by the layer formation.
- Active substances and / or fillers can also be accommodated in the core or in the jacket or in both.
- the core can be extruded as a monofilament or also multi-core, and the core and / or the jacket can optionally also be foamed during extrusion or afterwards.
- the invention relates to a bristle which is obtained from the filament produced according to the invention by cutting to length as desired, and to a bristle article with a bristle carrier to which bristles of the aforementioned type are attached to form the bristle trimmings or a part thereof.
