Prior art

The invention relates to a multicomponent dental brushes with improved visual and/or odorous effects, due to the properties (e.g., transparency) and structural configuration (e.g., the use of a main component having a protrusion) of the components of the toothbrush.

Toothbrushes are often made of a plurality of components having differing from the point of view of hardness, structure, color, etc. properties, to obtain the finished product that possesses many desirable characteristics, such as ease of grasping, good flexibility and high durability. However, the range of possible combinations of components that can be combined through conventional production techniques, is limited by the compatibility of the components, which, in turn, depends on the individual composition components. Thus, despite the fact that toothbrushes may be desirable Association of aesthetic features (e.g., three-dimensional effects) and even odorous substances to improve the attractiveness of the product to the user, the components required to obtain these properties, are often not easy to combine effective and/or cheapest way. For example, a combination of transparent and opaque plastics may require �use. chemical adhesives or adhesives are acceptable for connection of these components.

Summary of the INVENTION

Aspects of the invention relate to a toothbrush comprising at least two components, such as molded plastic, having different optical properties (e.g. transparency). In illustrative embodiments, the components are chemically compatible so that they could be acceptable to adhere to each other without adhesive.

Components are combined to provide visual effects such as the appearance of three-dimensional elements (e.g., protrusions) in the main component at different depths beneath the overlying (or covering) transparent or partially transparent second component. For example, if the second component is only partially transparent, it can be used to cover the surfaces of the protrusions of the main component layer of variable thickness will lead to variable degrees of visibility of these surfaces. The surface of the projections coated with a relatively thick layer of partially transparent plastic component, can only be barely visible compared to the surfaces of the projections are covered with a relatively thin layer (or uncovered, i.e. protruding partially through a transparent plastic component). If required, the underlying surface of the main component can be essentially completely clouded, leading to the result that the surface� protrusions appear suspended in the partially transparent second component.

This variability in the extent to which the properties of the main component can be visually hidden or visible, also applicable to other sensory effects associated with the main component. For example, the release of odorous substances from the main component may vary in such a way that the surface of the lower component (area or point), covered with a relatively thick layer of the second component (e.g., a partially transparent plastic), emit odorous substance in the main component at a relatively low level compared to surfaces coated with only a thin layer or perhaps completely spaced on the outer surface of the toothbrush. The level of release of odorous substances per unit area depends on the diffusion kinetics of odorous substances through the overlying second component, which often contains no odorous substances.

In alternative embodiments, the second components, or other components of the toothbrush may contain odorous substances in the same, lower or higher concentrations compared with the main component. In any case, from this disclosure it will be clear how the different thickness of the component and the concentration of odorous substances can be used to modify and adjust wysw�of rojdeniya odorous substances from different parts of the outer surface of the toothbrush (e.g., sections handle).

Consequently, aspects of the invention relate to the toothbrush containing a main component having a region for grasping and a region in contact with the oral cavity. The second component covers at least the area of the main component in the area for grasping. The main component includes a plurality of protrusions in a region for grasping, and the second component is at least partially transparent and covers the main component of the layer.

Further aspects of the invention relate to a toothbrush, discussed above, containing a main component having a region for grasping and a region in contact with the oral cavity, and a second component that covers the plot of the main component in the area for grasping. The main component and the second component are chemically compatible, so that the components can satisfactorily adhere to each other without the use of chemical adhesive, binder or even mechanical locking components.

Other aspects of the invention relate to the toothbrush containing a main component having a region for grasping and a region in contact with the oral cavity, as discussed above. The main component contains odorant. The second component is covered by a layer of varying thickness by at least a section of the main component in the area for grasping to provide different levels of release of odorous substances in this field.

These and other aspects of the invention will become apparent from the following detailed description.

DETAILED description of the INVENTION

Aspects of the invention relate to multi-component dental brushes having a variety of different commercial advantages, not only due to the types of materials used in components, but also structural elements, light transmitting properties and other properties of these components. The combined properties of the individual components of the vantage� provides an attractive organoleptic effects which may include visual effects and/or effects of the perception of odorants (olfactory). According to some variants of implementation, the elements, such as three-dimensional structures in the main component of the toothbrush can be visible through the transparent or translucent second component. Therefore, a change of the depth at which the main component elements are under the second component, changes the degree to which the elements visible to the user. Similarly, if the primary component contains the odorous substance, the level of diffusion of the substance to the outer surface of the toothbrush (and, ultimately, to the user) may also be adjusted by varying the thickness of the layer of the second component.

Thus, one or more organoleptic effects (e.g., visual or olfactory) or characteristics of the toothbrush can be easily adjusted by selection of appropriate parameters (e.g., degree of transparency of the components, the thickness of the coating of one component with another, the concentration of odorous substances in components, etc.). Consequently, aspects of the invention relate to dental brushes having outer portions (e.g., portions of the handle) with more than one degree of visibility of structural elements and/or more than one level freeing up the smell�. These characteristics arise when the components of the toothbrush have properties and are combined as described herein.

Toothbrushes according to the invention is made by combining at least two components having different optical properties (e.g. transparency). Materials suitable for components of toothbrushes, include polymeric materials, such that can be subjected to molding under pressure. In the illustrative embodiment of the two components that are in contact for the formation of a toothbrush, or at least form part of the toothbrush, where the visual elements, such as projections of the main components, as shown through the transparent or translucent second component, both contain a polyolefin (e.g., polyethylene such as high density polyethylene, polypropylene, a mixture of polyolefins such as ethylene-propylene mixture or an olefin copolymer, such as a statistical ethylene-propylene copolymer).

The use of two components containing or even primarily consisting of polyolefins, provides important advantages from the point of view of the chemical compatibility of the components. Chemically compatible components, such as both the representative of the family of olefins, may adhere to each other without using a separate �Lenogo layer or binders. Chemically compatible components may also be connected in a satisfactory way without the relatively complex mechanical lock, which is sometimes used between the components of the toothbrush that are not chemically compatible (e.g., contain different materials, as in the case when one component contains predominantly the polyolefin, and the second component contains mainly poliolefine, such as polystyrene, polycarbonate or styrene-Acrylonitrile).

Therefore, according to some variants of implementation of the components of multi-component toothbrushes according to the invention contain no adhesives, binders and do not use a mechanical lock between the components. According to other variants of implementation of the adhesive, the binder and/or mechanical locks can be used even with chemically compatible components to achieve a relatively stronger and more durable connection between the components than that which can be achieved by using components that are not chemically compatible. In other embodiments, relatively lower amounts of adhesive or binder, and/or a relatively lower degree mechanical fixation can be used to achieve the connection between chemically compatible�bubbled components comparable in strength and solidity of the connection between two components that are not chemically compatible.

In view of the above description it is obvious that the compound is chemically compatible components (for example, both contain mainly polyolefins) according to aspects of the invention simplifies the manufacture of toothbrushes to reduce the cost and other significant advantages. Such advantages include greater ease of processing (for example, the elimination or shortening of the drying stage before molding). In the case where there are two components and both contain polyolefins, benefits include the preservation of physical strength when used in a normal environment of the mouth (due to the chemical inertness of these components) and reducing material costs.

Fig. 1-3 depict various views of one component, referred to here as the first or main component 10 used in the illustrative toothbrush according to the invention. The main component 10, as shown, can provide a basic design of the toothbrush and, therefore, the main source of some properties of the finished toothbrush, such as strength, flexibility/rigidity, etc. are Desirable for the primary component 10 form can be achieved by injection molding from the polyol�ina, such as polypropylene, as discussed above.

The main component 10 may include one or more areas for grasping (position 12 in Fig. 2) or areas that are usually captured or held by the user. The main component 10 may also contain a region 14 that is in contact with the oral cavity, or area, which is usually made with cleaning elements, such as tufts of bristles that are attached to the teeth of the user. Narrowed portion 16 may be divided and placed between these areas and according to Fig. 2 can provide the two-piece structure in which the front segment contains a region 12 for gripping and the rear segment contains a region 14 that is in contact with the oral cavity, wherein the front segment is tilted or at an angle (i.e. not on the same line) relative to the posterior segment. For example, the front segment can be tilted (i.e., is offset from a straight line) at an angle from approximately 5 ° to approximately 40º relative to the posterior segment.

As best seen in Fig. 2, the main component 10 includes a protrusion 15, which form a three-dimensional decorative design. The projections 15, as shown in Fig. 2, protrude from the surface 20 in the field of 12 for grasping the main component 10. It should be borne in mind that the protrusions can �be made in other places of the main component 10, and that the term "protrusions" can refer to any of the plurality of elements extending or projecting from the main component 10, such as simple columns, shown in Fig. 1 and 2, embossing, best shown in Fig. 1, or the elements having other shapes horizontal cut, such as round, oval, star, heart, cartoon characters, etc. which may protrude through the second component of transparent or translucent material to provide a visually appealing effect. In addition, it should be understood that three-dimensional decorative design in the main component 10 can be created cutouts in the underlying surface 20, instead of spikes on the underlying surface 20, if only in this form the protrusions 15.

According to some variants of implementation, the protrusions 15 can provide visual effects that improve recognition trademarks and/or help to associate the toothbrush with related products (e.g., toothpaste), which has similar visual characteristics, and which can be packaged together. For example, the surface 18 white square or rectangular protrusions in the area for grasping the main component 10, as shown in Fig. 1, may be similar to that of particulate matter soluble refreshing breath of the substance ot�esena in packaging toothpaste, that they are visible.

As shown in Fig. 2, the projections 15 may extend or protrude from the surface 20 of the main component 10 at more than one height and/or be visible to varying degrees through the second component lying on top of or covering these projections layer of different thickness. As detailed below, at least one and possibly several or more of the plurality of protrusions 15 extending from the main component 10, can pass through the entire second component.

Therefore, the protrusions 15 protruding at different heights, can provide the surface 18a, 18b, 18c ledges at different levels over the underlying surface 20, directly below the protrusions 15 of the main component 10. For example, the surface 18a, 18b, 18c of the projections may be located on first, second and third height above the underlying surface 20, two or all three of these heights differ. Therefore, the second component can be easily applied on top of the ledges 15 and all adjacent surrounding underlying surfaces 20, for example, in the field of 12 for grasping the main component 10, to cover the main component 10 by a layer of varying thickness in this area.

Thus, the lower surface 20 may be covered with an essentially uniform layer of the second component, the first thickness, while the surface� 18a, 18b, 18c of the projections may be coated with a second component of the second, third and/or fourth thickness. Second, third and fourth thickness may be different from the first thickness, and may also differ from each other. Thus, the second, third, and fourth thickness can be, in essence, all the same, or essentially all different, or only some of the thickness can be essentially the same compared to the other depending on the desired visual effect. If the overlying second component is partially transparent, it can be used to cover the surfaces of the protrusions of the main component at essentially the same thickness will lead to essentially the same degree of visibility of these surfaces of the projections through the second component.

In the illustrative version of the implementation depicted in Fig. 2, the first and second surfaces 18a, 18b of the projections (e.g., located at different heights above the underlying surface 20) covered by a second layer, a translucent component on the second and third differing thickness, while adjacent the lower surface 20 is covered with a first thickness that is different from the second and third thicknesses. Thus, for example, the surface 18b of the ledge, which rises above the underlying surface 20 is larger than the surface of the protrusion 18a, b may�you covered with a translucent layer of the second component is relatively smaller thickness to ensure the best visibility of the surface 18b of the ledge and weaker visibility (or more turbidity) surface 18a of the projection. The surface protrusions can be any shape, as discussed above, relative to the forms section of the projections. The surface protrusions typically have areas that form attractive to the eye elements, including squares or rectangles with an area of approximately 1-10 mm2. The surface protrusions may have a larger or smaller area, as in the case of one or more protrusions that taper, essentially, to a point, creating a visual image in the form of a small point or points.

As discussed above, according to some variants of implementation, the thickness of the second component covering the surface of the ledge, can be zero, so that the surface of the protrusion (or the plot of a plurality of surfaces of the protrusions) may pass through the second component. This version of the implementation depicted for illustrative toothbrush of Fig. 4, a simplified cross section of the toothbrush in the area for grasping is shown in Fig. 5. As shown in these drawings, the surface 18b of the projections protrude through the second component 40 that covers the plot area for grasping. These surfaces 18b of the projections are covered with the second component 40 by a layer of third thickness which is zero, so are fully visible. However, other surface 18a of the projections are covered with the second component 40 of the second layer thickness�; which may be, for example, approximately 2 mm, whereas the adjacent underlying surface covered with a layer of a first thickness, for example, approximately 4 mm, which differs from the second and third thicknesses.

As shown in Fig. 5, the surface 18b of the projections passing through the second component 40 are essentially flush with the surface of the second component 40 so that the protrusions 15 and the second component 40 together form a smooth, or substantially smooth outer surface in areas where there is a second component, such as a pen or other parts of the region for grasping. According to other variants of implementation, the visible surfaces of the protrusions 18b may extend above the surface of the second component 40, or be recessed below the surface.

Therefore, in the embodiment of the Fig. 4 and 5, the lower surface 20 (covered with a first layer thickness) of the main component 10 to be clouded (or less visible) than some surface 18a of the projections (covered with a second layer thickness), which, in turn, more turbid than the other surface 18b of the projections (covered with a layer of third thickness which is zero in the case of Fig. 4 and 5). By adjusting the transparency of the overlying second component 40 may be possible to almost completely or completely muddy the underlying surface 20 (d�her barking, essentially invisible) and also to provide a clear-cut distinction between the relative visibility of the surfaces 18a, 18b of the projections coated with a layer of different thickness). Thus, it is possible to obtain the desired effect, for example, modeling of objects that are "immersed" in varying degrees in a translucent second component. Additional surfaces of the projections, for example, in the form of inscriptions (see Fig. 1) can be coated with the second component layer of such thickness that, in essence, is any of the first, second or third thickness, or covered with another layer of different thicknesses.

The second component according to aspects of the invention covers the main component with more than one layer thickness to ensure organoleptic effects such as visual effects, described above. Usually the main component of the toothbrush is covered in only one or more areas (such as at least a section of a pen or a region for grasping, but often not the entire handle), where the desired organoleptic effects. Therefore, in other areas that are not covered, the thickness of the second component can be considered equal to zero. According to the above description, in this case we can say that the second component covers the main component (which includes the surface(s) of the projections and the underlying surface) b�more than two different thicknesses, or more than one thickness, different from zero, having discrete values (for example, approximately 2 mm and approximately 4 mm) to provide the described herein the visual effects. According to some variants of implementation of the second component covers the main component, for example, in the plot area for grasping by a layer with a maximum thickness of approximately 8 mm, and typically about 5 mm.

In those areas where it is required, such as the plot of a pen or a region for grasping, wherein the second component is used for coating of the main component, the second component can be manufactured using injection molding. As discussed above, the second component is used to cover the surface of the protrusions, which are formed from protrusions in the main component and adjacent underlying surfaces. These surface protrusions can be performed on any part, including in-depth area of the main component, which, if required, the second component by injection molding. Should take into account that the main component used to perform the projections, may be, but not necessarily, the internal component of the toothbrush. For example, the main component may be located on the inner Central component thus, h�about the main component is actually located between the Central component and the second component. The determining factor is what can be achieved discussed above visuals, and various combinations of components to achieve this goal will become apparent to those skilled in the art based on the present disclosure.

As discussed above, the second component is predominantly chemically compatible with the main component to provide a suitable adhesion/adhesion between these components. Thus, if the primary component includes a polyolefin, the second component may be, for example, polypropylene or statistical ethylene-propylene copolymer. To ensure the above described visual effects, in which main component elements are visible in varying degrees through the second component, the main component and the second component can have different transparency. For example, the main component may be almost opaque (for example, have an opaque white color or other opaque color), whereas the second component can be at least translucent (for example, to have a translucent blue color). Of transparency or full opacity can be achieved, for example, by modifying the second component illuminating the substance with a degree of transparency depending on the concentration of bleaching agents.

The degree WWS�corruption or transparency of the second component will be to determine the extent to which the tabs (for example, the bars, the emblem of the product or other elements) in the main component are visible through the second component of varying thickness. In the illustrative embodiment of the good visual effects are obtained when the second component has a maximum value of turbidity is equivalent to approximately 20% (e.g., from approximately 5% to approximately 20%) at a thickness of 2 mm and the maximum value of turbidity is equivalent to approximately 45% (e.g., from about 25% to about 45%) at a thickness of approximately 3 mm. the Value of turbidity can be measured in accordance with ASTM D-1003 for transparent parts. Clarified the second component can be used in its natural color or can be slightly tinted with colorants, known in the art, including soluble dyes, such as Milliken Clear Tint® (Milliken Chemical, Spartanburg, S. C.).

Preferably other organoleptic effects of the entire toothbrush can be included in and regulated in a manner similar to that discussed above for visibility projections of the main component (for example, by changing the thickness of the overlying second component and/or transparency of the second component relative to the base component). In the case of smelling (scent or olfactory) effect, for example, the smell of polymeric materials, in particular the polyol�ins, can be obtained by mixing the odorous substances, perhaps together with the carrier directly to these materials prior to molding under pressure.

Odorous substances for polymeric materials include aromatic oils and other liquids that are slowly released, as described, for example, in U.S. patent No. 6334974. Media, mixed with odorous substances include polymers, such as polyolefins (e.g., polyethylene and ethylene vinyl acetate copolymer. Odorous compositions comprising a fragrant substance, and a carrier, can be used for cooking odorous plastics having a wide range of possible odors or fragrances, including scents of vanilla and mint. Examples of such compositions include compositions marketed under the brand name PolylFF® from the company International Flavors and Fragrances, Inc. (new York, NY). Can also be used combinations of odorants.

Specialists in the art can easily determine the media types odorous substances that are compatible with the materials of the components used in the toothbrush. In General, odorous substance, if used, is included as a fragrant composition with a carrier component, such as a principal component, in such quantity that has not changed significantly the characteristics of the main component. Such clicks�zoom, the main component containing mainly polyolefin, such as opaque white polyethylene, may be impregnated with a fragrant substance in such a quantity that the desired properties and characteristics of the main component (e.g., color, adhesion/connection with other polyolefin-containing components, machinability, strength, etc.) were essentially preserved.

A typical weight ratio of odorous composition (i.e. United odorous substances and media) to the main component or other component (e.g., second component) is in the range from about 1:20 to about 1:5 and often in the range of from about 1:19 to about 1:9. The amount of added odorous substances depends on the required strength of the smell coming out of the toothbrush, and the duration of excretion of smell. Specialists in the art can easily determine the relative amount of odorous substances to achieve the desired level of release of odorous substances (for example, which is generally perceived as pleasant by most users) for a long period (for example, the estimated shelf life of the toothbrush).

The use of different thickness in the second component for covering a main component containing odorant, drive�t to different levels of release of odorous substances in different areas of the outer surface of the toothbrush. For example, according to the embodiment of the Fig. 5 some surface 18b of the projections of the main component 10 can pass through the second component 40 that covers the plot area for grasping, while the other surface 18a of the projections are covered with the second component 40. In the case where the main component 10 contains the odorous substance, and the second component 40 is no, the level of release of odorous substances from the surface 18b of the projections will be higher per unit area than the rate of release of odorous substances from the surface 18a of the projections.

Similar to how varies and is subject to the visibility, as discussed earlier, the rate of release of smell can also be varied and regulated. Thus, the surface 18b of the projections covered by the second components 40 a layer of a third thickness equal to zero, are fully visible and allocate the maximum level of odorous substances per unit area of the surface 18b of the projections. Other surfaces 18a of the projections coated with a second component 40 by a layer of a second thickness, emit relatively low levels of odorous substances per unit area due to the containment through the second component. Adjacent the underlying surface can be covered (even more) layer of the first thickness so that the release of odorous substances per unit area of these �of overhasty minimized.

Therefore, by changing the thickness of the layer that the second component covers the main component, it is possible to provide different levels of release of odorous substances from the primary component per unit area. Just as the protrusions can be made with two, three, four or more discrete degrees of visibility (e.g., by establishing that the number of said discrete values of the thickness of the overlying layer of the second component), these projections may likewise release odorous substance with two, three, four or more discrete levels per unit area to provide the desired combination of organoleptic (visible and olfactory) effects.

Therefore, according to some variants of implementation, the level of release of odorous substances per unit area through the surface protrusions may correspond to (e.g., be proportional to) the degree of light transmission to these surfaces (i.e. visibility). In other embodiments, the implementation of these relevant optical and olfactory effects may not be required and could be adjusted independently. For example, independent adjustment of the visibility of the surfaces of the projections are possible by changing the relative transparency of the main component and the second component, while similarly netavis�may control the level of release of odorous substances from the surfaces of the projections are possible by changing the concentration of odorous substances in these components. From the point of view of the present disclosure, it should be borne in mind that may be subject to many other factors to obtain the desired combination of visibility and properties of the discharge of odour from the surfaces of the protrusions, including the thickness of the components and the relative transmission components and characteristics of distribution of odorous substances components.

According to the illustrative implementation options, only one of these two components will have at least some transparency and/or one of these two components will contain odorous substance. As discussed above, often the main component is opaque, and the second component is at least partially transparent. Similarly, often the main component contains (e.g., impregnated) odorous substance, and the second component does not contain anything except the number that comes and penetrates from the primary component to the second component after bonding of these components.

In addition to the main component and the second component described above, the toothbrush of the invention may have other components. For example, in the area for grasping can use the third elastomeric component, which is shown as element 50 in Fig. 4. The third component 50 may be additionally formed on the Il� be molded together with the main component or other components to provide improved grasping in the area for grasping and/or other functional components.

In the illustrative embodiment of the Fig. 4 the third component 50, namely a thermoplastic elastomer, covers the additional section of the main component in the area for grasping, are not covered by the second component 40. The third component 50 can be used, for example, to cover and area for grasping by the fingers, and region for grasping with the thumb in the area for gripping on opposite sides of the handle of the toothbrush, thus providing a non-slip grasping surface that improves the user's control over the brush, especially in the context of environmental moisture or suspension. The third component can also be used in area that is in contact with the oral cavity, for example on the side opposite to the beams 55 of the bristles or other cleaning elements on the toothbrush head. With this arrangement, the third component may provide additional functions, including cleaning of the tongue, the removal of dental plaque and/or gingival massage.

Illustrative elastomers suitable for use in the third component include thermoplastic elastomers, such which contain polyolefins (for example, olefin homopolymers and olefin copolymers), ethylene-propylene rubbers and elastomers (e.g., ethylenepropylene monomer), styrene-butadiene-styrene, STI�ol-ethylene-butylene-styrene, the polyesters or polyurethanes. Hardness Durometer or hardness values of these elastomeric materials generally lie in the range from about 10 to about 70 on a scale of shore A.

Described in this document toothbrushes can optionally include additional components, including other elastomers with hardness from 0 to 70 shore A. such additional elastomers are generally physical and mechanical properties that are different from the third component. Additional elastomers, for example, may be additionally formed on the main component and/or the second component at the production stage, which occurs separately from the application of the third component. Additional elastomers can provide aesthetic properties and functions that differ from those in the third component.

Thus, toothbrushes described herein can provide a variety of sensory effects, including visual effects, odorous effects or a combination of these effects. These effects can come from surfaces, such as surfaces of the projections having a plurality of degrees of visibility and/or multiple levels of allocation of the smell.

Described in this document, aspects of the invention can be included in a manual toothbrush or an electric toothbrush. �the shepherd, the invention has been described in relation to specific examples, which include preferred at the present time the methods of the invention, specialists in the art it is clear that numerous possible variations and modifications.

SUBSTANCE: device comprises a cleaning head with conductive fibre bristles which are used to feed a potential for the electrochemical activation of the dental bleaching agent, e.g. peroxide nearby the teeth. A complex impedance device system (62) or an optical device system (27) provides the information whether the bristles with the conductive fibres are nearby the dental surface or nearby the gingival surface. The first of the above systems - the complex impedance one - uses an electrical signal through a fibre to determine the complete impedance of a chain comprising a tooth or a gingival surface with the complex impedance supposed to vary in accordance with the fact if the tooth or the gingival surface is involved into the chain. The optical system generates a light beam, which is directed to the oral cavity surface through the conductive fibre with the return light colour showing if the surface is dental or gingival. If it is the tooth that is detected, the dental bleaching agent is activated on the bristle, whereas determining the gingival tissue keeps the dental bleaching agent inactive on the bristle.

EFFECT: structural improvement.
