Definitions
- the invention relates to a toothbrush with the features the preamble of claim 1 and a method for making a plastic bristle for a such a toothbrush.
- the bristles are usually made from extruded monofilaments circular cross section. Other cross sections are also have already been proposed.
- the cleaning effect of such Toothbrushes, as well as a desired massage effect Gingiva occurs almost exclusively through the bristle ends, those to avoid injuries and recessions the gingiva are rounded. So far the bristle end to meet two opposing requirements, namely on the one hand a sufficient brushing effect on the Exercise tooth, on the other hand a reserved massage of the gingiva.
- the one in the foreground Cleaning effect of the tooth surfaces and interdental spaces is therefore inadequate due to compromise.
- the invention has for its object a toothbrush to propose with profiled bristles that with unchanged Strength properties an increased, however nonetheless have gentle cleaning and massage effects and which are inexpensive to manufacture.
- the bristle according to the invention can be extruded manufacture and can be refined in the same way, like a conventional bristle. It has the advantage that in addition to the bristle end the apex of the helix or its transition into the flanks and the flanks even because of the large pitch of the helix Brush edges that form the cleaning effect strengthen the tooth surfaces and interdental spaces without endanger the gingiva. Even if one penetrates Such bristles in the interdental spaces cannot be used Jamming the bristle will come because the helix is very steep and there are no radial constrictions.
- the helix can move due to its few gears twist on train so that on the bristle anyway no pull-out forces come into effect that would be higher than with normal bristles.
- By comparative steep slope of the helix is the number of effective Edges limited on the circumference, so that despite the better Cleaning effect in connection with the rounded
- the crown of the helix is still sufficiently gentle Treatment of the teeth and a gentle massage effect the gums are guaranteed. Rounding the spiral crown can preferably on the occasion of extrusion of the monofilament but also subsequently by mechanical or thermal processing.
- At least one Part of the bristles have a single or multi-start spiral, which makes the surfaces effective during cleaning be enlarged and at the same time different directions of action arise.
- the bristle designed according to the invention in any case a stronger scraping abrasive effect on tooth enamel and gingiva exerts essentially as usual bristles cylindrical monofilaments and consequently for consumers with very sensitive gums or sensitive Tooth necks is not suitable due to the Different colors of helix and core for the consumer the property of the brush signals, so that he the can select a toothbrush adapted to its purpose.
- the Plastic for the coil can be colored by pigments be. Because the pigment particles can be harder than that The filament can be made of plastic matrix simply by coloring get a certain abrasive effect.
- the core and the at least one preferably exist Spiral made of different materials.
- the at least one helix to certain operating conditions be adjusted in particular with regard to their hardness.
- the user can use a different color Design of the core and the helix Reference to the brush properties of the respective brush are given.
- Such bristles can be easily can also be obtained in that the monofilament polygonal, preferably square cross section having. After twisting, each edge then forms one Spiral.
- the bristles have a predetermined rigidity or elasticity have to.
- the stiffness can be adjusted in achieve preferred embodiment of the invention if the core is a soul and a cloak surrounding the soul made of different materials.
- the materials for the soul and the mantle the stiffness and elasticity of the bristles on the one hand and their effect in dental care on the other hand in influence and vary as desired.
- the one on the Mantle ribs can either be made from its Material or a different material.
- the monofilament or the monofilament from an elastic Plastic. That way they can be taken out the bristles material produced in the longitudinal direction stretch what a reduction in their diameter with brings itself so that, for example, after insertion pulled into an interdental space more easily can be and not in the interdental space jam. Jamming is also prevented by that the bristle can twist when pulled out.
- the bristles can only be on one part have a helix in their length.
- spiral bristles with bristles combine different configuration and process together.
- the invention proposes that a Extruded monofilament with at least one axially parallel rib, then twisted and finally the twist is fixed.
- the bristles can then pass through Cut to length from an endless strand.
- Another method is to make a monofilament a plastic together with on the outer surface extending ribs made of a plastic of other properties co-extruded, then the co-extruded Composite twisted and finally the twist fixed becomes.
- the one forming the helix Plastic can be adapted to the intended use.
- the core can be made from the bristles Plastic exist, while the plastic for the Spiral softer or harder or with abrasive Fillers can be provided. It can also be helical Rib-forming plastic colored differently to enable a functional display.
- the core can also be broken down by area different materials exist to make the bristle adapt to their intended use.
- the core has an inner area and one surrounding the inner area Sheath made of different materials that are co-extruded become.
- Another way of making it is that extrudes at least two monofilaments, then twisted and the twist is fixed. You can the monofilaments during extrusion or after Twisting are inextricably linked.
- the bristle designed according to the invention also gives the Possibility that the extruded monofilament or the coextruded Composite stretched before twisting and optionally stabilized to the bristle with the Spiral the properties required by bristles for toothbrushes to rent.
- the bristle ends must be trimmed be rounded to damage teeth and Avoid injury to the gingiva. This happens with Advantage by surface melting of the bristle ends, because the ends of the thin-walled coil in front of the core melt and consequently the sharp edges first regress.
- Bristle is also excellent as or for interdental cleaners suitable.
- Surrendered to an interdental cleaner other benefits if only in a sub-area its length is twisted.
- the untwisted section has smaller cross-sectional dimensions and can be thus easier to insert into an interdental space.
- the Insertion can be made even easier if the untwisted section at least in sections for example, cross-section flattened by pressing having.
- the toothbrush according to FIG. 1 has a head 30 and a handle 31, which has a flexible neck 32 are interconnected.
- the head 30, the handle 31 and the neck 32 are injection molded in one piece from plastic.
- On bristles in the form of bundles 33 are attached to the head 30.
- the bundles 33 are shown only schematically, they each consist of a plurality of bristles Plastic by welding, injection or on are mechanically attached to the head 30.
- FIG. 2 shows a single bristle 1 from a bundle 33 reproduced. It consists of a circular cylindrical Core 2, on the outer surface of which a two-start helix 4 is arranged with the two coils 5, 6. Every spiral 5, 6 has a flattened upper rounded head 7 or 8 on.
- a bristle for toothbrushes can, for example an outer diameter in the range of 0.2mm have, the core 2 having a diameter in the range from 0.1 to 0.15mm.
- the spiral points at the for Toothbrushes usual length of the bristles up to 1.5 cm a Number of gears from 2 to 6.
- the bristle according to Figure 2 can be different produce.
- FIG. 4 shows an extruded monofilament 9 with approximately triangular cross section consisting of a core 13 and three ribs 14, 15 and 16 is formed.
- Figure 5 shows a Monofil 9 with cross-shaped cross section, which in turn a core 17 and four symmetrically arranged ribs 18, 19, 20 and 21.
- the drill axis falls on everyone Embodiments with the axis of the core 2 together.
- the monofilament can also have a substantially rectangular, e.g. have square cross section, the area near the center, the core and the four corner areas form the ribs.
- Figures 6 to 8 show essentially the same cross-sectional shapes like Figures 3 to 5, but in in this case, the circular cylindrical cores 10, 13, 17 with the ribs 11, 12 or 14 to 16 or 18 to 21 co-extruded.
- the extruded monofilament or the coextruded The composite is then stretched, twisted and thermally stabilized and stored for 1 to 2 days.
- FIGS. 9 through 11 show similar cross-sectional shapes as shown in Figures 6 to 8, but the Cores 10, 13, 17 a core 10a, 13a or 17a and one have the sheath 10b, 13b and 17b surrounding the soul.
- the soul and the coat consist of different ones Materials.
- the ribs 11, 12 or 14 to 16 or 18 to 21 consist of a further material.
- the soul is co-extruded with the sheath and the fins and then edited in the manner mentioned.
- the soul 10a, 13a and 17a can be used for toothbrush bristles typical plastic consist of all positive strength properties to ensure a conventional bristle while the plastic material for the coat 10b, 13b, 17b and for the ribs 11, 12 or 14 to 16 or 18 to 21 to the desired cleaning and / or Massage effect can be coordinated.
- the head of the Ribs flattened or rounded.
- the usage side Rounded ends preferably by superficial Melt while the fastener ends melted individually or in groups into a head become.
- the bristle 1 or the monofilament from which it is made also includes one rectangular, preferably square cross section exhibit. After twisting, the edges then form this cross-section one rib each.
