Definitions

  • the invention relates to a toothbrush head comprising a cleaning element carrier with a plurality of cleaning elements, an entirety of the cleaning elements forming a cleaning element body, the cleaning element body having a surface with an outer surface and a top surface.
  • the invention further relates to a system comprising a toothbrush head and an information carrier.
  • Toothbrushes are known today in a large number of variants.
  • the types of cleaning elements of the toothbrushes can be varied, the cleaning elements differing in material, shape and arrangement.
  • Toothbrushes are known which comprise differently colored types of cleaning elements.
  • the US 2016/0015163 A1 shows a brush head with a variety of filament tips that define a work surface.
  • the Filament tips are colored with at least two different colors, so that an enlarged graphic replica is given a functional characteristic.
  • the characteristic can include, for example, the cross-sectional shape of a bristle filament that is otherwise barely visible to the eye.
  • the US 6,033,733 (Colgate Palmolive) shows a toothbrush with bristles of different colors. This marks an area on the bristle field to indicate to the user where and how much toothpaste should be applied.
  • the bristles have different colors inside and outside the ring.
  • the known brush heads have the disadvantage that a relatively low information density can be achieved.
  • the object of the invention is to create a brush head which belongs to the technical field mentioned at the outset and which is provided with a greater information density than in the prior art.
  • a first cleaning element function type is defined by elongated cleaning elements (eg thin filaments)
  • said cross section of the cleaning element is defined essentially perpendicular to the longitudinal orientation.
  • the cross section is therefore generally parallel to the main surface of the cleaning element carrier
  • a top surface character against a top surface background is defined in that this character is recognizable on the cleaning element body when the cleaning element body is viewed from a viewing position lying on the toothbrush head orientation axis and at a distance from the cleaning element body and the cleaning element body is in front of the cleaning element carrier.
  • the cleaning element body is then viewed from a viewing position lying on the toothbrush head orientation axis and at a distance from the cleaning element body, and one of the at least one character can be recognized on the cleaning element body.
  • Another advantage is that the production of a range with different toothbrushes can be made more efficient. Also a large number Different toothbrushes can be easily distinguished with the alphanumeric characters.
  • the toothbrush head comprises a cleaning element carrier with several cleaning elements.
  • the entirety of the cleaning elements forms a cleaning element body.
  • the cleaning element body is thus arranged on the cleaning element carrier.
  • a toothbrush head can also comprise a plurality of cleaning element bodies, in particular if two cleaning element groups are separated by a plane, in particular a plane perpendicular to a longitudinal direction of the brush head.
  • the cleaning element body defines a surface, a distinction being made here between a top surface and a lateral surface.
  • the cleaning element body preferably has an essentially prismatic shape, preferably a shape of a straight prism, a top surface preferably being convex, in particular essentially rectangular, hexagonal, oval, etc.
  • the cleaning element body does not necessarily have to be designed as a prism.
  • the cleaning element body can have, for example, a shape of a truncated pyramid with any base area, it being possible for both the base face of the truncated pyramid and the top face of the truncated pyramid to be designed as a cover surface.
  • the outer surface is defined by a convex end around the cleaning elements.
  • the lateral surface is thus also understood to be a convex shape when the cleaning elements are arranged, for example, in a jagged, star-shaped, etc. Distances between the cleaning elements through the lateral surface are also not taken into account.
  • the cover surface can be flat, in particular parallel to the cleaning element carrier.
  • a plane of the top surface can also enclose an angle with a plane of the cleaning element carrier.
  • the top surface can also be curved.
  • the top surface is basically to be understood as a convex surface, with which, for example, distances between the Cleaning elements are disregarded.
  • the top surface is thus defined by the distal ends of the cleaning elements.
  • two partial cover surfaces can be offset from one another, provided that an area of the cleaning element carrier is occupied with shorter cleaning elements than another part of the cleaning element carrier.
  • the cover surface as a whole can thus be stepped several times.
  • a symbol (or a part thereof) on the cover surface is preferably shown such that it is undistorted in a viewing direction perpendicular to the cover surface. If the symbol (or a part thereof) is on the lateral surface, it is preferably shown in such a way that it can be seen undistorted in a viewing direction perpendicular to the lateral surface. A distortion of the character can of course also be wanted.
  • the viewing angle at right angles to the top surface or to the outer surface can depend on the exact location depending on the design of the surface (for example, if the top surface is curved).
  • the sign can also pass from the outer surface to the top surface, so that no clear viewing angle can be defined from which the sign is ideally visible.
  • the sign can also be displayed along the lateral surface in such a way that the viewer has to rotate the toothbrush about an axis parallel to the lateral surface.
  • two characters can be applied on the lateral surface in such a way that the first character can be seen from a first viewing angle and the second character can be seen from a second viewing angle.
  • an outer contour can be zigzag-shaped, the zigzag sides alternately showing part of the first or second character.
  • Holographic representations of characters or the like can also be provided.
  • the cleaning element carrier is preferably formed from a copolymer comprising acrylonitrile, butadiene and styrene.
  • This copolymer is known in the trade with Polylac ABS, whereby batch ABS white is preferably used for a toothbrush.
  • the alphanumeric character is preferably a character which can be recognized in the context as an alphanumeric character.
  • a single line, a dash, or a single X is not necessarily interpreted as an alphanumeric character.
  • the two characters are commonly interpreted as alphanumeric characters and possibly even interpreted as Roman nine.
  • Other alphanumeric characters are in turn easily interpreted as such on their own and treated in the present case, in particular, for example, the letters A, B etc. But even the one can be recorded as an alphanumeric character on its own, provided that it has been elaborated accordingly and thus graphically via the Representation of a simple line goes beyond.
  • the surface preferably has at least two alphanumeric characters.
  • the range of inscriptions can thus be increased further.
  • the surface can also have exactly one character. This can be on the top surface or on the outer surface. Furthermore, the sign can also be arranged going from the top surface to the outer surface.
  • the top surface preferably has at least two alphanumeric characters. Due to the typical format of a cleaning element body, two characters can be arranged on the top surface in a particularly optimal manner. Typically, two characters can be displayed relatively large, whereby an area of the top surface can be used particularly optimally. However, if smaller characters are provided, the top surface can also have more than two characters.
  • At least two characters can be provided on the lateral surface.
  • the signs of the outer surface do not necessarily have to match those of the top surface.
  • the outer surface can generally be provided with signs all around.
  • the lateral surface can be provided with the same or different characters on both sides.

  • characters with a clear expression are preferred, for example letters such as C, U, L, O etc.
  • Alphanumeric characters preferably differ and the background differs in one color. This creates a contrast, making the character particularly easy to read.
  • the background and the sign can only differ in terms of color intensity or grayscale.
  • the background and the sign can also be black and white, whereby the sign can be both black and white.
  • the characters can also be fluorescent, illuminated under UV light, etc.
  • the toothbrush head can include different types of cleaning elements.
  • a typical representative of cleaning elements are the filaments.
  • the term cleaning element type is understood below to mean a specific type of filament with a specific dimension (length, diameter, cross-sectional shape) and a specific material.
  • a type of cleaning element thus comprises cleaning elements that are identical with regard to the cleaning effect or with respect to the shape, the material and the surface structure.
  • cleaning elements of a cleaning element type can differ in terms of their appearance, in particular the color, so that a cleaning element of a single cleaning element type can be used both as a symbol and as a background.

  • other cross-sections can also be provided, in particular X-shaped, star-shaped, semicircular, etc.
  • the filaments preferably have the same cross-section over the entire filament length.
  • cross-sectional changes can also be provided, in particular the filaments can taper in one direction or taper at the distal end.
  • the filaments are preferably formed from polyethylene or from a polyester, in particular from polybutylene terephthalate.
  • polyester for the filaments has the advantage that the filaments can be made finer than e.g. B. with nylon filaments. This is due to the fact that polyester has higher strength and largely irrelevant water absorption. In fact, nylon loses you up to 9% through water absorption Part of its strength when wet, so nylon brushes require filaments with a 50% larger diameter.
  • Polyethylene has the advantage that it is easy to process and inexpensive.
  • the filaments can also be made from other substances known to the person skilled in the art which are suitable for toothbrushes.
  • At least 50% of the top surface is preferably formed by filaments, in particular filament tips.

  • cleaning elements are known to the person skilled in the art.
  • filaments and other cleaning elements can also be used for a sign. Basically, the filaments can differ from one another, in particular in a cross section, a length, the material etc. However, exactly one type of filament is preferably used. This has the advantage that a homogeneous background for the sign is created, with which optimal contrasts can be achieved.
  • the toothbrush head can only have cleaning elements which do not comprise filaments.
  • the cleaning elements preferably exclusively comprise filaments.
  • a toothbrush head is thus obtained, which forms a good base for the characters.
  • the cleaning elements particularly preferably comprise only one type of filament, so that the filaments match in terms of length, cross section, material and surface quality. This enables a particularly optimal background for the sign to be achieved. Alternatively, different types of filaments can be provided.
  • individual cleaning elements can be provided which are not in the form of filaments.
  • a filament diameter is preferably between 0.02 mm and 0.3 mm, in particular between 0.08 mm and 0.15 mm.

  • the range of filament diameters between 0.08 mm and 0.15 mm forms an optimal balance between the cleaning effect and the substrate for the sign.
  • a filament diameter can also be smaller than 0.02 mm or larger than 0.3 mm.
  • the brush head preferably comprises more than 1000 filaments. This in turn creates a particularly homogeneous background for the sign. Especially in connection with correspondingly small filament diameters, a large number of filaments is to be preferred in order to achieve the largest possible area coverage. Furthermore, a large number of filaments has the advantage that with individual coloring of filaments, in particular the filament tips, if the sign is provided on the cover surface, a particularly high image quality can be achieved for the sign.
  • the brush head has more than 1500 filaments, preferably more than 3900, particularly preferably more than 5400, in particular more than 7000 filaments.
  • fewer than 1000 filaments can also be provided.

  • the filaments can also be distributed uniformly over the cleaning element carrier.
  • the toothbrush head can also comprise a single tuft of filaments.
  • Adjacent tufts are preferably at a distance from one another which is smaller than a tuft diameter. Because the tufts are arranged relatively close together, a dense surface is achieved which is optimally suitable for the application of characters.
  • adjacent tufts can also have larger distances from one another. This can be accepted in particular if the tufts fan out from the cleaning element carrier, so that the gaps between the tufts are at least partially closed.
  • the large cover area creates a dense surface, making the sign particularly easy to display.
  • the cover surface can also be covered by tufts to less than 1/4.
  • the tufts are arranged on the cleaning element carrier in such a way that the entire lateral surface is covered by tufts.
  • a correspondingly close occupation of the tufts that is to say a small distance between adjacent tufts, can be provided.

  • a tuft preferably comprises more than 10 filaments, in particular between 30 and 300 filaments.
  • a large number of tufts can make a particularly homogeneous one Background for the sign can be reached.
  • the manufacture of the brush head can be kept inexpensive with a small number of tufts.
  • an optimal range between achievable image quality and production costs is achieved.

  • more than 300 filaments or fewer than 10 filaments can be provided per tuft.
  • the tufts preferably have a round cross section. This enables a particularly simple and inexpensive production of the brush head, since tufts with a circular cross section can be mounted particularly easily on the cleaning element carrier due to the rotational symmetry.

  • the cleaning element body 100 forms a projection surface for the characters to be applied to the surface through the top surface 101 and the outer surface 102.
  • the letter F is applied to the surface in such a way that part of the letter F lies on the outer surface 102 and the rest of the letter F lies on the top surface.
  • the viewing area has a character on a background that extends over several tufts of cleaning elements.
  • the character is formed by three bold straight lines.
  • the background is around these lines.
  • the lines of the letter are blue and the background is white. This means that at least the filament tips (or alternatively the whole filament) are colored differently, depending on whether they form the symbol or the background.
  • gaps between the filaments and filament tufts 110 and minor unevenness, which are caused, for example, by the shape of the filament tufts on the lateral surface 102, are neglected.
  • the human brain is able to fill such gaps and smooth unevenness, so that a sign 120 applied to the cleaning element body 100 is sufficiently clearly visible.
  • the Figures 3a - 3c each show a schematic representation of a side view of a toothbrush 10 according to FIG Figure 1b , with several applied characters, the characters being applied to the outer surface.
  • the character string "CX-B8" is applied to the outer surface. This code can, for example, designate a toothpaste to be used with the toothbrush or can be linked to other information.
  • the Figure 3b shows an embodiment of a toothbrush 10, in which the character string "orange” is reproduced in a special font on the outer surface.
  • the character string can denote, for example, a toothbrush class to which the present toothbrush 10 can be assigned on the basis of certain criteria.
  • Figure 3c a toothbrush 10, in which the character string "code” is shown with characters arranged one above the other in the longitudinal direction of the brush.
  • the characters can in principle also be applied diagonally or in some other way on the lateral surface. All of the character strings are applied regardless of the arrangement of the filaments or the tufts, so that largely any character can be applied to the lateral surface in any orientation.
  • the Figures 4a - 4j each show a schematic representation of a top view of the first embodiment of the tuft arrangement with characters applied to the cover surface.
  • individual tufts 110 are now used as pixels, so that the characters follow a predetermined grid of tufts 110.
  • the background with black tufts 112 and the character "S" with white tufts are shown again.
  • any other colors can be provided for the sign and the background, provided that a sufficiently large contrast between the sign and the background can be achieved.
  • Figures 4b a capital C
  • the Figure 4c shows an 8.
  • the entire top surface is used for the sign. Of course, this is not absolutely necessary. So can too several characters are displayed one above the other.
  • the characters L and C are shown one above the other.
  • the Figure 4e shows an M over a c and the Figure 4f shows a P above the lowercase letter r.
  • the top surface can also be provided with characters in the transverse direction.
  • the Figure 4g shows the two characters c and o next to each other, the Figure 4h shows a Q and an X and the Figure 4j finally shows a 2 and an X, whereby a different font is chosen for the X than for the X the Figure 4h .
  • the Figures 4a - 4c show examples in which there is only a single character on the top surface and in which the cleaning elements belong to a single cleaning element function type. If the cleaning element body has at least two different cleaning element function types in these examples, there is a possible optical effect which results when viewing the top surface due to the different cleaning element function types, regardless of the symbol shown. In other words, according to the invention, the character is not visible in that the background and characters are formed from the different types of cleaning element functions. The arrangement of the cleaning element function types is therefore independent of the representation of a character.
  • top surface or lateral surface
  • a cross-sectional shape of a cleaning element function type If, for example, an "o" is shown as a sign, then according to the invention this is not the cross section of a tubular (i.e. round, hollow) cleaning element.
  • the Figures 5a - 5f each show a schematic representation of a top view of a second embodiment of a tuft arrangement with characters applied.
  • the second embodiment of the tuft arrangement comprises five rows of tufts.
  • the first and fifth rows comprise 7 tufts 210
  • the second and fourth rows comprise 8 tufts 210
  • the third row comprises 9 tufts 210.
  • the rows are arranged hexagonally so that a tuft 210 inside is in contact with 6 tufts 210 .
  • the external shape is hexagonal.
  • the cleaning element body 200 thus comprises more tufts 210 and thus also more pixels in order to be able to form a character.
  • the top surface can be provided with characters in landscape format.
  • the Figure 5d shows the digits 9 and 7 next to each other, the Figure 5e the letters X and A side by side, the two bush letters overlapping in a white tuft 211, and the Figure 5f finally shows the digits 3 and 8 next to each other.
  • the Figures 6a - 6b each show a schematic representation of a top view of a third embodiment of a tuft arrangement with characters applied.
  • the cleaning element bodies 300 comprise a tuft field with 4 x 6 tufts 310, which are arranged in a Cartesian manner and thus form a rectangle.
  • a black B is shown with the white tufts 312 and the black tufts 311, in which Figure 6b an S is shown analogously.
  • the Figure 7 shows a schematic representation of a plan view of a third embodiment of a tuft arrangement with applied characters.
  • a first cleaning element body comprises white tufts 412 and black tufts 411, with which a C is shown.
  • a second cleaning element body now additionally comprises two cleaning bars 420, which are not provided with a sign in the present case.
  • cleaning elements such as, for example, the beams present, can be provided with characters both on the jacket side and on the cover surface.
  • the Figures 8a - 8c each show a schematic representation of a top view of an embodiment of tuft arrangements, with characters applied. In these exemplary embodiments, the characters are not applied according to the grid specified by the tuft arrangement.
  • the cleaning element body 200 of the Figure 8a is designed according to the second embodiment and is provided with the letter F, with both black tufts 211 as the background and white tufts for representing the F and black and white tufts 213, which are used both for the background and for the representation of the F. Through this representation of the characters, any shape can be applied to the top surface.
  • the Figure 8b shows the first embodiment of the cleaning element body 100, wherein a C is applied to the cover surface.
  • the Figures 9a - 9c each show a schematic representation of a top view of embodiments of a cleaning element body with an applied symbol, the cleaning elements not being arranged in tufts.
  • the cleaning elements are in turn designed as filaments.
  • these cannot be identified as individual tufts, but are evenly distributed over the cleaning element carrier.
  • the "code" strings are free and independent of the filament arrangement on the top surface.
  • individual filaments or filament tips 612 are black for the representation of the character string and the other filaments or filament tips 611 are white for the representation of the background.
  • the Figure 10 shows a system comprising a toothbrush 10 with an applied symbol and an information carrier 700.
  • the information carrier 700 is designed as a product catalog.
  • Code CX-B8 in the catalog refers to information related to the toothbrush.
  • accessories compatible with toothbrush 10 can be identified using the code in Catalog 700.
  • Further information, such as the order number of the toothbrush etc., can also be found in the catalog. Any number of other applications are known to the person skilled in the art.
  • the cleaning element carrier can also have a coupling device for a handle or an electric toothbrush.
  • a brush head is created which can be provided with a high density of information.
