Definitions

  • the invention relates to brushes with a handle forming bristle carrier and bristles attached to it, with the bristle holder areas highlighted in color having.
  • the invention further relates to methods for Manufacture of such brushes.
  • Brushes especially cleaning and care brushes, such as Body brushes, toothbrushes etc. are very useful when in use exposed to different stresses.
  • First are the permanent exposure to moisture, water or the like.
  • Second depending on the type of brush Actions by chemically and / or mechanically acting Agents such as dish soap, soaps, dentifrices, as well by fats, colors and the like. Add to that the hand of the user on the handle acting holding and friction forces.
  • Such strains are toothbrushes in particular, but also others Hygiene brushes and technical brushes exposed.
  • the invention has for its object for brushes the attachment more permanent for any purpose To enable information or decorations of any kind and methods of making such brushes propose.
  • This object is achieved according to a first variant of the invention solved in that the plastic of the bristle carrier at least in the differentiated areas Laser beams absorbing and changing color reacting pigments is filled, and that this Areas using laser beams on the bristle holder are upset.
  • the task takes place Solution in that the bristle carrier at least near the surface Area of at least two layers Plastics with different absorbency for laser beams, of which the top layer with the lower absorbency transparent or is translucent and the lower layer has the greater absorption capacity has, and that the color contrast Areas using laser beams on those with color change reactive lower layer are applied.
  • the information be attached by means of laser beams that according to the contour of the areas to be optically highlighted are preferably controlled by computer.
  • the first solution variant react the LS-absorbing Pigments with a color change at the irradiated areas.
  • the second solution variant turns on the laser beams the boundary layer between the two plastic layers absorbs and finds the desired color change there instead, by the transparent or translucent Top layer is visible.
  • the boundary layer of the plastic of the top layer molecular be restructured, resulting in an even stronger contrast formation given is. So upset areas with contrasting colors are not indicated by chemical, still due to mechanical stresses, such as they occur when using brushes. They also do not detach from the bristle holder, stay rather preserved permanently.
  • the contrasting colors Areas can be designed small and filigree become what is not possible with previous methods is.
  • the areas highlighted in color can be different Be kind, it can be information different Content, e.g. act as regulatory information, which in the series production of different brushes as Sorting and packaging information are used.
  • the information may be related to color or image recognition devices for the automation of transport and packaging tasks can be used.
  • the information can also provide the user with properties display the brush or be instructions for use.
  • brushes used in the commercial sector due to hygiene regulations only for certain Purposes may be used and so far by different Colors were marked, now by indelible ones Labeling can be differentiated.
  • brushes for hospitals that are for the areas of kitchen, operating and treatment rooms and patient rooms must be marked differently have to.
  • the inventive design of the brush shows her Advantages particularly obvious with toothbrushes. This are subject to increased hygiene requirements since they are in the mouth be used and there are also additional stresses are exposed. This is particularly true for children's toothbrushes where the head is not just that is exposed, but often due to uncontrolled or unwanted chewing movements is claimed. Limit on toothbrushes To this day, the information is largely based on the representation of a brand, the name of the manufacturer or the like. And can this information only on the with the Mouth not provided in contacting handle become.
  • the invention allows attachment to a toothbrush the information on both the handle and the head, since it is neither impaired by the influences mentioned become detached. So can the toothbrush on the handle and / or head with one for their use essential property, for example the hardness of the Bristles ("hard”, “medium” or “soft”), marked become. It can also provide information about the useful life, within the proper oral and dental care is guaranteed, but also warnings are appropriate become. The latter are necessary because in the modern Dental care Toothbrushes constructive and material to be adapted to different needs and for a toothbrush designed for a specific need another need for damage to teeth or gums can generate.
  • sorting and packaging identifiers be attached for mass production different toothbrushes an automatic sorting and packaging or the compilation of Allow ranges.
  • the bristle carrier at least near the surface Area made up of two layers of different colors There is plastics, and that the top layer under Formation of the colored areas using laser beams is worn. Removing the top layer takes place by melting and gasifying the constituent Plastic instead, so that the different colored plastic is exposed below the top layer.
  • the information is advantageously good visible surfaces of the handle, so with a toothbrush on the underside facing the bristles and / or on the top of the handle facing away from the bristles. But you can also, especially if it is to indicate degrees of hardness on the toothbrush head be appropriate, so far from technical, but also was not possible for hygienic reasons.
  • the invention further relates to a sales unit that from a brush, in particular toothbrush of the aforementioned Structure and a color-contrasting receiving Areas of packaging, at least is partially made of plastic.
  • a sales unit that the packaging is at least partially made of a laser absorbing and plastic that reacts with a color change exists or is coated with such and the colored areas using laser beams are upset.
  • Packaging of the type in question is mostly formed as a blister pack, the transparent Blister part is applied to a carrier made of cardboard and the cardboard carrier the necessary information and desired decorative elements.
  • Training of the sales unit are the Information or decorations on the packaging in the same way as generated on the brush. You can the information on the toothbrush is at least partially be identical to the information on the packaging.
  • toothbrush matching information in particular also for those that are for the subsequent purchase or the reordering are crucial so that the consumer even after removing the toothbrush from the packaging can be certain when buying or reordering to get the same toothbrush.
  • mass production of toothbrushes with subsequent packaging line can use the laser devices for labeling the toothbrush and the packaging via appropriate If necessary, the same programs can be controlled in part become.
  • the invention further relates to methods of manufacture of brushes of the aforementioned construction, in which the Bristle holder by casting, especially injection molding generated and the bristles on the occasion of casting Embed in the plastic or afterwards on the bristle holder be attached.
  • the bristle carrier made of a plastic that with laser absorbing and pigments reacting to laser beams through color change is filled, poured and are after hardening of the plastic the areas to be highlighted by means of appropriately controlled laser beams up to Color change treated.
  • This laser treatment can be done at great speed perform so that the hourly output of a production line exclusively from the work cycle of the injection molding machine is determined. Despite this achievable Highly hourly performance can be highlighted in color Areas of any fineness and lines with a high degree of recognizability.
  • the second variant of the brush according to the invention is manufactured in that the bristle carrier at least is cast in two layers, first by a base body from a laser beam absorbing and onto this plastic filled with color-changing pigments poured, then at least on the color areas to be lifted a top layer of a transparent or translucent plastic with less Absorbance for laser beams is poured on and after the plastic has hardened, the colors to be highlighted Areas of the cover layer by means of controlled laser beams until the color of the pigments changes be treated in the basic body.
  • the brush can be manufactured in that the Bristle carrier is cast at least two layers, by first making a base body out of a plastic poured, then at least on the color contrast Areas cover a layer of a different color Plastic is poured on and after hardening the areas of the top layer to be highlighted by means of appropriately controlled laser beams are treated, until the plastic of the cover layer at least as far through Melting and gasification is worn away that the different colored Plastic of the body is visible.
  • All of the aforementioned variants of the method are preferred carried out so that the mass-produced Brushing after pouring and hardening of the plastic fed to a laser station with at least one laser device, positioned there and the contrasting colors Areas using at least one appropriately controlled Laser beam are treated.
  • the methods according to the invention achieve in particular then high effectiveness when the laser beam from one corresponding to the areas highlighted in color programmed computer is controlled, which is an advantage is when several programs for different in the computer configured, highlighted areas saved and the programs optionally while running Manufacturing of the brush can be accessed.
  • the production can be the information or decorations to be applied vary, for example, corresponding sorting characteristics for the subsequent packaging line or brushes with different Compile properties to assortments, which are packaged in the packaging line as an assortment can be.
  • the described, designed according to the invention Create sales units, being identical or partly identical information on the brush and the Packaging in turn in the computers of the laser devices at the Manufacturing and packaging line can be saved.
  • FIGS. 1 and 2 The toothbrush shown in FIGS. 1 and 2 exists from a handle 1 and a head 2, which over a slimmer neck 3 are interconnected. Handle 1, Head 2 and neck 3 are made of plastic. There are 2 on the head the bristles 4 attached.
  • the handle 1, possibly also the head 2 and the neck 3 are made of a plastic filled with pigments is that with laser irradiation with a color change react.
  • Lasers can be on the handle 1 or on the head 2, namely its back, a color-contrasting area in shape an information 5 indelible and in hygienic attach in perfect shape.
  • the toothbrush is through special training of the bristle trim or the bristles are primarily suitable for to remove dark plaque, which is advantageous in Connection with an appropriate dentifrice happens. However, you will not become such a toothbrush use for a tooth stock that has no plaque.
  • FIGS. 1 to 3 can be used accordingly the three variants of the invention.
  • Fig. 4 shows the first variant, in which the handle 1, Head 2 and neck 3 existing bristle holder with one Pigments filled plastic is injected. in this connection are such pigments that are caused by laser beams with a color change in the light or in the dark react (positive or negative). In the enlarged Detailed view of Fig. 4 are the places where this color change has taken place, designated 6.
  • the handle 1, head 2 and neck 3 existing bristle carrier formed two layers. It consists of a base body 7, which above all the necessary strength and usage properties conveyed and a sprayed top layer 8.
  • the Base body 7 in turn consists of a plastic relatively high absorption capacity for laser beams, while the top layer 8 has a lower absorbency has and transparent or at least translucent is.
  • the absorbency of the plastic of the Base body 7 can in turn by appropriate pigmentation can be achieved. React when exposed to laser the pigments by color change, which is shown in FIG the reference numeral 9 is indicated. It can be bright or dark contrasting colors act through the transparent or translucent cover layer 8 visible become.
  • the bristle carrier again from a base body 7 and a cover layer 8.
  • the injection molded base body 7 consists of a different color Plastic as the top layer 8. Becomes the top layer Exposed to laser beams, they reflect at the boundary layer and back into the top layer the plastic of the cover layer 8 on the laser beams melted and gassed points. These locations are designated by 10 in FIG. 6.
