Description

State of the art

[0001] The invention relates to a personal care product, in particular an oral hygiene product, preferably a toothbrush.

[0002] An oral hygiene product, in particular a toothbrush, with at least one application unit, with at least one handle unit and with at least one functional unit arranged on the application unit and / or the handle unit has already been proposed.

[0003] The object of the invention is, in particular, to provide a generic device with improved properties with regard to functionality and / or comfort and / or cleaning results. This object is achieved according to the invention by the features of claims 1 and 21, while advantageous embodiments and further developments of the invention can be found in the dependent claims. Advantages of the invention

[0004] The invention relates to a personal care product, in particular an oral hygiene product, preferably a toothbrush, with at least one application unit, with at least one handle unit and with at least one functional unit which is arranged on the application unit and / or the handle unit.

[0005] It is proposed that the at least one functional unit comprises at least one, in particular a single-piece, mechanical switching element made of an elastic material, which has at least two defined, static, and distinct states. The functional unit can, in particular, have various functions, such as, among others, a cleaning function, an information function, a protective function, a counting function, a reminder function, a design function, an animation function, a reservoir function, a comfort function, such as, in particular, a gripping function, a handling function, and / or an activity function. Preferably, the functional unit is arranged on the application unit or on the gripping unit. However, it would also be conceivable to provide several functional units, with one functional unit arranged on the application unit and one on the gripping unit.Preferably, when arranged on the handle unit, the functional unit forms a functional part of the handle unit. Preferably, when arranged on the application unit, the functional unit forms a functional part of the application unit. The functional unit is preferably fixedly, and in particular captive, attached to the handle unit and / or the application unit, especially to a carrier body of the handle unit and / or the application unit. The switching element preferably consists of a soft component; alternatively, materials for injection-molded bristles or, at most, individual thin-walled hard components are also suitable.Preferably, the switching element can be moved manually or with a simple tool from one static state to another, wherein the switching element preferably jumps automatically to the respective static state as it approaches it. Preferably, the switching element has a function for the primary application and / or an additional function. For example, the switching element can create a play element, such as for a child's toothbrush. Alternatively, the function of the switching element can be used for a non-play application, e.g., as a clamping element. The switching element can also perform several of the listed functions.

[0006] Preferably, the handle unit and / or the application unit has a support body which is provided for direct connection of the at least one switching element. The support body is formed, in particular, by a base body of the handle unit and / or by a base body of the application unit. Preferably, the support body is rigid so that it can form the basis for the switching element. The support body consists, in particular, of a hard component. Preferably, the support body is arranged at least partially around the switching element.

[0007] The inventive design of the personal care or oral hygiene product provides advantageous functional properties. In particular, the switching element allows for switching between different functions, or at least one function can be activated. Preferably, each static state can be assigned a function. Furthermore, a high level of user comfort can be provided. Additionally, the cleaning result can be positively influenced. In particular, an adjustable switching element can be provided, which has at least two fixed or end positions, each representing an equilibrium state. Transitional states, which form intermediate positions, are provided between these equilibrium states.The transition states are unstable, and the switching element switches to one or the other equilibrium state without significant load. The equilibrium states are each located along a motion vector in one direction or the other.

[0008] The term "oral hygiene product" refers specifically to a toothbrush and / or an interdental cleaner and / or a flosser and / or a tongue cleaner and / or a toothpick. Advantageously, the oral hygiene product is designed as a toothbrush, particularly a manual toothbrush, preferably a children's or adult toothbrush, and preferably a purely manual toothbrush. In particular, the oral hygiene product differs from an electric toothbrush. The oral hygiene product can be a disposable toothbrush, a reusable toothbrush, or a toothbrush with replaceable heads. However, the term "personal care product" could also refer more generally to a brush product. The term "brush product" refers specifically to an oral hygiene brush and / or a cosmetic brush and / or a hairbrush and / or a household brush.Examples of oral hygiene brushes include manual toothbrushes such as reusable toothbrushes, toothbrushes with replaceable heads, disposable toothbrushes, or single-tuft brushes; electric toothbrushes, including hybrid toothbrushes; interdental cleaners, especially those with twisted bristles (also called interdental brushes), in injection-molded form, or as flossers and / or tongue cleaners. Examples of body care or cosmetic brushes include mascara brushes, nail polish brushes, facial brushes, applicators, especially hair dye applicators, massage devices, makeup brushes, shaving brushes and / or wet razors, or other personal care products. Examples of household brushes include dish brushes, floor mops, and / or brooms. The following statements regarding oral hygiene products also apply to the aforementioned personal care products.

[0009] The oral hygiene product has, in particular, a longitudinal axis which is advantageously arranged at least substantially parallel to a principal direction of extension of the oral hygiene product. Preferably, the longitudinal axis runs at least partially within the oral hygiene product and, in particular, through its center of gravity. In particular, the longitudinal axis of the oral hygiene product is a central axis of the oral hygiene product and / or a central axis of the handle unit. A "central axis" of an object is understood to be, in particular, an imaginary axis that runs within the object parallel to a principal direction of extension of the object and intersects the object at no more than two points.The term "at least substantially parallel" here refers in particular to an orientation of a direction relative to a reference direction, especially in a plane, wherein the direction has a deviation from the reference direction of particularly less than 8°, advantageously less than 5°, and most advantageously less than 2°. The term "principal extension direction" of an object refers in particular to a direction that runs parallel to a longest edge of the smallest imaginary cuboid that just completely encloses the object. In this context, the term "principal extension" of an object refers in particular to the extension of a longest edge of the smallest imaginary cuboid that just completely encloses the object.

[0010] In particular, the oral hygiene product has a length, especially parallel to its longitudinal axis, of at least 110 mm, advantageously at least 130 mm, and particularly advantageously at least 150 mm, and / or at most 200 mm, advantageously at most 190 mm, and particularly advantageously at most 180 mm, whereby other lengths, particularly shorter or longer ones, are of course also conceivable. In particular, the oral hygiene product has a maximum width, especially parallel to a lateral axis of the oral hygiene product, advantageously perpendicular to its longitudinal axis and / or parallel to a principal plane of extension of the oral hygiene product and / or the handle unit, of at least 15 mm, advantageously at least 20 mm, and particularly advantageously at least 23 mm, and / or at most 40 mm, advantageously at most 35 mm, and particularly advantageously at most 31 mm.In particular, the oral hygiene product has a maximum height, preferably measured parallel to a height axis of the oral hygiene product, advantageously measured perpendicular to the longitudinal axis of the oral hygiene product and / or perpendicular to the main plane of extension of the oral hygiene product, of at least 10 mm, advantageously of at least 12 mm, and particularly advantageously of at least 15 mm and / or of at most 30 mm, advantageously of at most 26 mm, and particularly advantageously of at most 23 mm. The term "height" here refers in particular to a state of the oral hygiene product in which it is placed, for example, on a surface such as a tabletop, a sink, the top of a piece of furniture, or the like, especially such that its longitudinal axis is parallel to the surface.A "principal extension plane" of an object is understood to be, in particular, a plane that is parallel to a largest side face of a smallest imaginary cuboid that just completely encloses the object, and in particular passes through the center of the cuboid.

[0011] Advantageously, the application unit has at least one cleaning area designed for tooth and / or tongue cleaning, particularly in the user's oral cavity. Preferably, the cleaning area comprises at least one cleaning unit, in particular at least one brush head, advantageously a toothbrush head, preferably with multiple bristles and / or bristle bundles and / or injection-molded cleaning elements or injection-molded bristles and / or soft, elastic cleaning elements. However, the cleaning unit can also be designed, for example, as an interdental brush and / or as a single tuft (e.g., a single large bristle bundle) and / or as a floss-covered bow, in particular as a flosser, or the like. Furthermore, the application unit advantageously has at least the neck element, which is preferably connected to the cleaning area, in particular directly and / or integrally.The term "one-piece" is to be understood in particular as being joined by at least a material bond, for example by a welding process, an adhesive bonding process, an injection molding process, and / or another process that would appear appropriate to a person skilled in the art, and / or advantageously formed in one piece, such as by being manufactured from a single casting and / or by being manufactured using a single- or multi-component injection molding process, and advantageously from a single blank. The term "intended" is to be understood in particular as being specifically designed and / or equipped. The fact that an object is intended for a specific function is to be understood in particular as the object fulfilling and / or performing this specific function in at least one application and / or operating condition.

[0012] The oral hygiene product has, in particular, a front and a back, which are preferably arranged facing away from each other. Preferably, the cleaning area is located on the front of the oral hygiene product. The front is, in particular, a side of the oral hygiene product visible in a viewing direction perpendicular to both the longitudinal and transverse axes of the product. The front of the oral hygiene product is, in particular, the side of the brush on which the thumb rests. The front is also normally the side towards which the bristles are directed. The back is advantageously a side of the oral hygiene product visible in the opposite viewing direction. The back of the oral hygiene product is the side of the toothbrush opposite the bristles.The left side of an oral hygiene product is defined as the side that lies to the left when viewed perpendicularly from the front of the product. The right side of an oral hygiene product is defined as the side that lies to the right when viewed perpendicularly from the front of the product. The top side is defined as the end of the oral hygiene product where the cleaning area is located. The bottom side is defined as the end of the oral hygiene product opposite the top side, which is closest to the handle.

[0013] Preferably, the handle unit has at least one grip element, which is advantageously designed for one-handed gripping. Preferably, the grip element is at least partially tapered. This advantageously allows for a secure grip and optimizes ergonomics. Particularly preferably, the grip element is elongated, with one longitudinal axis of the grip element advantageously corresponding to the longitudinal axis of the oral hygiene product. The grip element is at least partially, and in particular entirely, made of at least one hard component. It would also be conceivable for the grip element to be additionally made of one or more soft components. Preferably, the material volume is made at least predominantly, and in particular entirely, of at least one hard component. In particular, the grip element advantageously includes at least one thumb grip area and / or at least one hand grip area.Advantageously, the thumb grip area is located on the front of the oral hygiene product, and particularly on the front of the grip element. It is conceivable that the thumb grip area and / or the handle area could have at least one element and / or a surface texture consisting of at least one soft component and / or at least one hard component.

[0014] Advantageously, the grip area has at least one handle element. Preferably, a main extension direction of the handle element is arranged at least substantially parallel to the longitudinal axis of the oral hygiene product. Advantageously, the handle element has at least one surface texture element, and particularly advantageously a plurality of surface texture elements, which are at least substantially identical or at least geometrically similar to the surface texture elements of the thumb grip area described above. Preferably, the surface texture elements of the handle element are arranged, particularly at least in pairs, in groups one behind the other along the longitudinal axis of the oral hygiene product.

[0015] The components used in the manufacturing process can be classified as follows: Conventional materials: Materials, essentially virgin materials, that are largely oil-based. Sustainable materials: as listed below and described later, preferably bio-based, biodegradable, and / or recycled. Bio-based materials: Material that is made from more than 40%, in particular more than 60%, preferably more than 80%, and most preferably 100% renewable raw materials. A further possible additional property of bio-based materials is, in particular, that the bio-based materials are biodegradable. Preferably, the materials are not based on foodstuffs such as, in particular, corn, sugar cane, etc. Biodegradable materials: Material that is biodegradable according to common standards. This includes, in particular, compostability (industrially or non-industrially).Materials made from renewable resources, especially petrochemical raw materials, can possess this property. Recycled materials: Materials that originate from a recycling process, such as post-consumer recycled materials, post-industrial recycled materials, ocean waste plastic, or social plastic.

[0016] The materials used can be recyclable. For recyclable materials, a recycling option after use is advantageous. Materials that can be integrated into an existing recycling stream, such as polyester (PET), polyethylene (PE), and polypropylene (PP), are particularly preferred.

[0017] The materials used can be recycled materials. Materials from a recycling stream, such as polyester (rPET), polyethylene (rPE), and polypropylene (rPP), are particularly preferred.

[0018] Within the scope of this disclosure, virtually any hard and soft components are eligible, which the person skilled in the art will suitably combine and / or select. Examples of hard components include styrene polymers such as styrene acrylonitrile (SAN), polystyrene (PS), acrylonitrile butadiene styrene (ABS), styrene methyl methacrylate (SMMA), styrene butadiene (SB), or the like. Furthermore, a hard component can comprise polyolefins such as polypropylene (PP), polyethylene (PE), or the like, particularly also in the form of high-density polyethylene (HDPE) or low-density polyethylene (LDPE). Furthermore, polyesters such as polyethylene terephthalate (PET), especially in the form of acid-modified polyethylene terephthalate (PETA), glycol-modified polyethylene terephthalate (PETG), polybutylene terephthalate (PBT), acid-modified polycyclohexylenedimethyl terephthalate (PCT-A), glycol-modified polycyclohexylenedimethyl terephthalate (PCT-G) or the like, are also suitable.Furthermore, the use of cellulose derivatives such as cellulose acetate (CA), cellulose acetobutyrate (CAB), cellulose propionate (CP), cellulose acetate phthalate (CAP), cellulose butyrate (CB), or the like is conceivable. A hard component can also include, for example, polyamides (PA) such as PA 6.6, PA 6.10, PA 6.12, or the like, polymethyl methacrylate (PMMA), polycarbonate (PC), polyoxymethylene (POM), polyvinyl chloride (PVC), polyurethane (PUR), polyamide (PA), or the like. In particular, polyethylene (PE) and / or polyurethane (PU) can be used as a hard component and / or as a soft component. In particular, a hard component has a modulus of elasticity of at least 1000 N / mm² and advantageously at least 1300 N / mm² and / or at most 2400 N / mm² and advantageously at most 1800 N / mm². Polypropylene (PP) is preferably used as the hard component.At least some of the materials listed under the hard component can be sustainable. In particular, materials containing cellulose are at least partially bio-based.

[0019] Advantageously, hard components are used for stable and / or structural elements, particularly in the handle element and / or in a support element of the application unit and / or the attachment unit, or the like. Preferably, the oral hygiene product, or at least a base body of the oral hygiene product, comprises a single hard component, which may be made of one of the aforementioned materials or a mixture thereof. However, combinations of different hard components are also conceivable, wherein these may, for example, be processed in a two- and / or multi-component injection molding process and / or bonded and / or welded together, in particular by ultrasonic welding. Alternatively or additionally, several hard components may be used that do not form a material bond in a two- and / or multi-component injection molding process.In particular, it is conceivable that in this case, a positive fit is created between the hard components, for example, in the form of at least one undercut and / or at least one through-hole and / or at least partial overmolding or the like. It is conceivable that, for example, a second hard component, which is particularly likely to be injection-molded onto a first hard component, shrinks and / or contracts after injection molding and advantageously forms a shrinkage bond. Suitable combinations could be, for example, polypropylene-polyester, polypropylene-sustainable material, polypropylene-styrene acrylonitrile, or other combinations. In this combination, polypropylene serves to create a material-bonded connection with the soft component.

[0020] Suitable soft components include, for example, thermoplastic styrene elastomers (TPE-S) such as a styrene-ethylene-butylene-styrene copolymer (SEBS), a styrene-butadiene-styrene copolymer (SBS), or the like. Furthermore, the use of thermoplastic polyurethane elastomers (TPE-U), thermoplastic polyamide elastomers (TPE-A), thermoplastic polyolefin elastomers (TPE-O), thermoplastic polyester elastomers (TPE-E), or the like is also conceivable. A soft component can also, for example, comprise at least one silicone. Advantageously, a soft component has a Shore A hardness of at most 90, more advantageously of at most 50, and particularly advantageously of at most 30. Preferably, at least one soft component forms a material bond with at least one hard component, particularly in at least one two- and / or multi-component injection molding process, advantageously by means of at least one overmolding and / or overmolding.The materials listed under the term "soft component" can be at least partially sustainable. The soft component can be a mixture of sustainable material and non-sustainable soft component. For example, the soft component can be a mixture of recycled polypropylene (rPP) and a soft component. Recycled polypropylene (rPP) can be a raw material for the production of a soft component. The weight fraction of recycled polypropylene in the soft component is more than 10%, preferably more than 20%, and particularly preferably more than 30%.

[0021] It is advantageous to consider that a hard component and a soft component used could have different colors, so that surface structures, lettering, motifs and the like can be realized by means of suitable design of the base body and soft element.

[0022] Furthermore, it is proposed that the at least one application unit comprises a brush head, in particular a toothbrush head. The application unit advantageously comprises at least one cleaning unit, in particular a toothbrush head, with bristles. The cleaning unit also advantageously comprises at least one bristle carrier, for example, a brush head body. At least some or all of the bristles are advantageously conventional extruded bristles. The bristles can, in particular, comprise at least one hard component and / or at least one soft component. Preferably, the bristles are made at least partially or completely of polyamide (PA) and / or polyester (PBT, PET), whereby any other materials (hard component or soft component) are conceivable, and sustainable materials such as chitosan are also possible. Furthermore, the bristles can be made of a biodegradable material.Furthermore, it is conceivable that at least some of the bristles have a pointed tip and / or a variable cross-section. Preferably, the bristles are made of a single material, or in particular, a mixture. However, bristles consisting of several components or materials are also conceivable, which can be produced and / or manufactured, in particular, by at least one co-extrusion process. The bristles can be produced and / or manufactured, for example, by extrusion, cutting to length, and / or post-processing. In contrast to injection-molded bristles or rubber-elastic massage and cleaning elements, which are manufactured by injection molding, conventional bristles are extruded, cut, processed, and inserted or anchored to the toothbrush handle using an adapted method, such as the anchor punching process, the AFT process, the PTt process, and / or the IMT process.

[0023] In particular, cylindrical or pointed bristles are suitable, with any cross-section being conceivable, such as polygonal, triangular, rectangular, square, elliptical, star-shaped, trapezoidal, parallelogram-shaped, rhombus-shaped, or any other cross-section. In particular, different bristles can be used within a single bristle bundle, as well as different bristle bundles, especially each containing a specific type of bristle. Bristles and / or bristle bundles can be arranged regularly or irregularly. In particular, bristles and / or bristle bundles arranged in groups and / or adjacent to one another can differ with respect to at least one characteristic, such as length, diameter, material, color, material hardness, geometry, point, and the like, especially in an alternating fashion.Preferably, the bristles have a diameter, particularly perpendicular to their longitudinal axis, of at least 0.075 mm and / or at most 0.25 mm. Advantageously, the bristles have a cross-sectional area, particularly perpendicular to their longitudinal axis, of at least 0.002 mm² and / or at most 0.2 mm². In the case of bristles used in cosmetics, for example, bristles of an additional application element, thinner bristles and / or bristles with a smaller cross-section can also be used, in particular bristles with a diameter, particularly perpendicular to their longitudinal axis, of at least 0.025 mm and / or at most 0.2 mm and / or with a cross-sectional area, particularly perpendicular to their longitudinal axis, of at least 0.001 mm² and / or at most 0.15 mm².In the case of pointed bristles, polyester (PBT, PET, or PTT) is particularly suitable as a material, although sustainable materials are also possible. The pointing can be produced mechanically and / or chemically. Other materials are also conceivable. Preferably, the bristles are straight in the longitudinal direction, but wavy, twisted, helical, and / or coiled bristles are also conceivable, as are combinations of different bristles. Furthermore, bristles with a smooth surface are conceivable, as are bristles with a textured surface.

[0024] Furthermore, the bristles, particularly as bristle bundles, are preferably processed by at least one anchor punching process, an anchor-free tufting (AFT) process, an in-mold tufting (IMT) process, a PTt process, or the like, and are attached, in particular, to the bristle carrier. Preferably, the bristle carrier has a plurality of bristle receptacles, in particular holes for bristle bundles, which are drilled and / or formed during injection molding. In the case of anchor punching, for example, it is conceivable that a base body, in particular made of a hard component, preferably the brush head, is first manufactured by injection molding, advantageously forming blind holes for bristle bundles during the injection molding process. Of course, subsequent drilling of blind holes is also conceivable.Preferably, bristles or bristle bundles are then folded and fastened in a blind hole by means of at least one anchor, in particular by punching. A loop punching method is also conceivable.

[0025] Alternatively, as mentioned, anchorless methods are also conceivable, whereby bristles or bristle bundles are advantageously not folded. In this case, the bristles or bristle bundles are approximately half the length compared to an anchor-stamped process. For example, it is conceivable that the bristle bundles are first separated, fused, and / or their bristle ends are subsequently overmolded, particularly for attachment. Bristle bundles can be advantageously combined in this process. Manufacturing using the in-mold tufting process is possible, whereby a base body, for example, the brush head and / or the handle unit and / or the attachment unit, is advantageously formed during the overmolding of the bristle ends.It is also conceivable that, particularly within the framework of an Integrated Anchorless Production, bristles are first overmolded with plates or the like, and these plates are then overmolded again, for example to form the brush head and / or the handle unit.

[0026] Furthermore, it is conceivable that the application unit is composed of a base body and a bristle plate, which is fitted with bristles and / or alternative cleaning elements. For this purpose, bristle plates with through holes are first manufactured by injection molding, through which bristles are then inserted. Preferably, the bristles are then connected on a back side, in particular fused, preferably to each other and / or to the corresponding bristle plate. In this way, bristle-covered bristle plates can then be welded and / or bonded to a base body, in particular a brush head, preferably by ultrasonic welding. For this purpose, the base body, in particular the brush head, has a recess into which the bristle plate can be inserted.A well-known manufacturing method in this context is the anchor-free tufting process, which particularly facilitates the joining of bristle bundles. The underside of the bristle plate is specifically defined as the side that is placed in a recess of the base body and faces the back of the oral hygiene product. Similarly, the top side of the bristle plate faces the top of the oral hygiene product.

[0027] Another method for anchorless bristle application involves manufacturing, in particular by injection molding, a brush head with through-holes for bristles. Bristles can then be guided through the through-holes and fused on the back side, particularly to each other and / or to the brush head. Preferably, the fused areas and / or the brush head are then overmolded, in particular with at least one soft component.

[0028] Furthermore, it is conceivable to first manufacture a brush head with blind holes, for example by injection molding and / or by drilling the blind holes. In this case, bristles are bundled together and fused and / or otherwise joined at one end. The brush head is then heated, in particular to the glass transition temperature of its material. Bristle bundles can then be advantageously inserted into the blind holes and anchored to the brush head by pressing them in. In particular, the heated blind holes or their surroundings deform in this process, so that the bristle bundles are anchored within them.

[0029] As an alternative or in addition to stamped and / or welded and / or glued bristles, injection-molded bristles are also conceivable. These can be manufactured together with the application unit, the handle unit and / or the mounting unit, particularly during multi-component injection molding, or subsequently injection-molded onto a base body of the application unit.

[0030] Another possible method for attaching bristles to the brush head is twisting. In this process, filament is fed from a spool, with several strands of filament wound onto a single spool. For machine feeding, several spools are pre-tensioned, as each filament in the brush corresponds to a single strand. The filaments are spread out to the correct width for insertion into the brush. The filaments are then pre-exposed so that they are free for the next step, allowing a wire to be guided over them. A wire is then fed from a spool to the machine, i.e., unwound and fed into the process. The wire is cut to a length greater than the unwound length of the twisted brush; the final trimming to the correct length occurs after twisting.The wire is bent into a U-shape so that the open end can be slid over the filaments to thread the bristles. The wire is held at the base of the U. The open end of the wire is then clamped to hold the filaments between the wire pieces. The filaments are cut to a length greater than the final length required for the brush, ensuring the brush can be cut correctly once the filaments are twisted in. The wire is twisted to clamp and secure the filaments. After the filaments are fixed within the wire, they are cut to the correct length and shaped. Once the brush section is complete, any excess wire is trimmed.

[0031] Preferably, during an injection molding process, particularly a two- and / or multi-component injection molding process, the materials of the injected bristles do not form a material bond with other soft and / or hard components and / or durable materials of the oral hygiene product. Instead, the injected bristles are preferably connected by means of a form-fit connection, for example, by means of at least one undercut and / or at least one through-hole and / or by means of at least partial overmolding with soft and / or hard components, whereby a shrinkage connection and / or a shrinkage connection are particularly conceivable. However, a connection by means of at least one material bond is also conceivable.

[0032] For all the injection molding processes mentioned, single-, two-, and / or multi-component injection molding is fundamentally possible. The materials used, especially different soft and / or hard components, can be joined by material bonding and / or form-fitting, as mentioned. The formation of articulated, movable, or flexible connections using suitable injection molding steps is also conceivable. Hot runner, cold runner, and / or co-injection processes are all possibilities.

[0033] Alternatively or additionally to a brush head with bristles, the application unit may also include at least one tongue cleaner and / or at least one alternative cleaning and / or massage element. These may each be made of a soft component, a hard component, or a combination of soft and hard components, and / or may be advantageously manufactured by injection molding.

[0034] Preferably, injection-molded bristles are at least partially and advantageously entirely made of a thermoplastic polyurethane elastomer (TPE-U). The use of a modified polyurethane elastomer (TPE-U) is conceivable, which may be modified, in particular, with regard to improved flow properties and / or rapid solidification, especially rapid crystallization, advantageously even at higher temperatures. Of course, other materials for injection-molded bristles are also conceivable, for example, thermoplastic polyester elastomers (TPE-E), thermoplastic polyamide elastomers (TPE-A), polyethylene (PE), for example in the forms of low-density polyethylene (LDPE) or linear low-density polyethylene (LLDPE), or the like. Materials for injection-molded bristles advantageously have a Shore D hardness of at least 0 and particularly advantageously of at least 30 and / or at most 100 and advantageously at most 80.In particular, a higher Shore hardness for injection-molded bristles is advantageous than for other soft components used, such as handles, massage elements, additional cleaning elements, or the like. The materials used for manufacturing injection-molded bristles can be sustainable materials.

[0035] In principle, the use of water-soluble polymers is also conceivable, for example for hard components, soft components, injected bristles or other elements of the oral hygiene product.

[0036] Similarly, sustainable materials, especially bioplastics, can be used for the hard component, the soft component, and / or the material for injection-molded and / or conventional extruded bristles. These materials can be derived from renewable resources. Potential raw materials include corn, hemp, sugar, castor oil, palm oil, potatoes, wheat, sugar cane, sugar beets, rice husks, rubber, wood, castor oil (also known as the castor bean plant), and similar substances. Suitable base materials could include cellulose, starch, PLA, glucose, chitin, chitosan, lignin, casein, gelatin, and similar substances, from which appropriate bioplastics can be synthesized.

[0037] The main groups of preferred bioplastics include starch-based bioplastics, cellulose-based bioplastics, polyhydroxyalkanoates (e.g., polyhydroxybutyric acid (PHB)), polylactic acid (PLA), and aliphatic / aromatic copolyesters. Other preferred bioplastics include lignin-based bioplastics.

[0038] In this context, a "functional unit" is understood to mean, in particular, a unit designed to provide an additional and / or extended function to the oral hygiene product. Preferably, the unit is designed to provide a function, especially one that goes beyond a basic function, to the oral hygiene product, either permanently or optionally. Various functions that would appear useful to a person skilled in the art are conceivable, such as a cleaning function, an information function, a protective function, a counting function, a reminder function, a design function, an animation function, a reservoir function, a comfort function (such as, in particular, a gripping function, a handling function, a marking function), and / or an activity function.In the case of a cleaning function, a cleaning function that goes beyond the basic cleaning function can be provided, in particular by means of the functional unit.

[0039] Furthermore, in this context, a "mechanical switching element" shall be understood to mean, in particular, an element that can be switched mechanically, especially manually or with a simple tool, between different states and / or positions. Preferably, the mechanical switching element has several, in particular at least two, defined static states that are distinct from one another. It is also conceivable that the switching element can assume several stable states, such as 3, 4, or 5 states. Preferably, the mechanical switching element is elastically deflected in at least one of the defined static states. Preferably, at least one static state constitutes a relaxed state of the mechanical switching element.Preferably, the mechanical switching element can be brought from a first static state, in particular a rest state, into a further static state by elastic deformation, which differs significantly from the first state with regard to shape and / or orientation. Preferably, the switching element can be manually moved from one static state to the further static state by an operator, wherein the switching element preferably springs into the respective static state automatically when approaching it. Preferably, the mechanical switching element consists of a soft component or an elastic material, such as an elastomer or silicone. Preferably, the switching element has at least one switching cap, which is dome-shaped, in particular hemispherical, in the first state, in particular the rest state.Preferably, the toggle cap is reversible, forming a dome on the opposite side. The toggle element is designed, in particular, as a "pop it" or "push pop" mechanism. Preferably, the toggle cap is designed as a single "pop it" or "push pop" bulge. Preferably, the mechanical toggle element is formed in one piece. "One piece" is understood to mean, in particular, formed in a single unit. This single unit is preferably manufactured from a single blank, a compound, and / or a casting, particularly preferably by an injection molding process, especially a single- and / or multi-component injection molding process. The toggle element is formed, in particular, by an elastic element.An "elastic element" is understood to be, in particular, an element that can be repeatedly deformed without being mechanically damaged or destroyed, and which, in particular, tends to return to at least one of the static states independently after deformation.

[0040] For smaller toggle switches, it can be easier to use a tool to perform the switch, for example, if switching by pressing with a finger is not possible. This tool could be a pen, a ballpoint pen, or a thin cylindrical rod. Smaller toggle switches that are not so easy to switch may be intentionally designed, for example, if switching is only rarely necessary or should not be easily possible. For instance, such a switch is used for the function indicating the end of use, since the function is set once and should not be easily changed afterward.

[0041] The term "intended" is understood to mean, in particular, specifically programmed, designed, and / or equipped. The fact that an object is intended for a specific function is understood to mean, in particular, that the object fulfills and / or executes this specific function in at least one application and / or operating state.

[0042] Furthermore, it is proposed that the at least one switching element preferably has exactly two defined static states that are distinct from one another: a first equilibrium state, in particular an initial state, and a second equilibrium state, in particular a deflection state. The first equilibrium state is, in particular, a rest state of the switching element. The first equilibrium state is, in particular, an unloaded state. Preferably, the switching element is at least partially pre-tensioned in the second equilibrium state, in particular the deflection state. This allows, in particular, targeted switching between exactly two static states. An operator can, in particular, select and set a state suitable for a given application.Preferably, the switching element can be moved manually by an operator, in particular by applying a pressure force to the switching element, from one static state to another static state. From an intermediate position between the equilibrium states, the switching element always switches to one or the other equilibrium state, depending on the intermediate position. The equilibrium states are, in particular, a rest position or a balanced position.

[0043] At least one switching element can have a customized feel and / or function. For example, different switching elements, through their varying states of equilibrium on the oral hygiene product, can create an adjustable or individual feel or shape. The same is possible for functions such as tongue cleaners, bristle fields, cleaning elements, and / or other mentioned functions. With multiple switching elements, it is particularly possible to incorporate a color scheme between the different switching elements. For instance, switching elements can be positioned next to each other and display different colors.

[0044] Furthermore, it is proposed that the at least one switching element has a substantial functional surface. In the initial state, the functional surface is the side equipped with functional elements and facing outwards. The functional surface is preferably oriented towards the front of the oral hygiene product. However, it would also be conceivable for the functional surface to be oriented towards the back of the oral hygiene product. Preferably, the functional surface is convexly curved in the first equilibrium state and concavely curved in the second equilibrium state. Preferably, the functional surface is dome-shaped, particularly hemispherical, in the first equilibrium state and bowl-shaped in the second equilibrium state. Preferably, the switching element is curved in the second equilibrium state on a side opposite to that in the first equilibrium state.Preferably, the switching element is convexly curved towards a front surface in the first equilibrium state and convexly curved towards a rear surface in the second equilibrium state. The functional surface is formed, in particular, by a top surface of the switching cap of the switching element. Preferably, the functional surface is arranged on a front surface of the oral hygiene product. More preferably, the functional surface is formed by a surface of the switching cap of the switching element facing the front surface.In this context, a "functional surface" is understood to mean, in particular, a surface of the functional unit, especially the switching element, which, in at least one state of the switching element, has a direct function, such as a display function, a cleaning function, a gripping function, an information function, a protective function, a counting function, a reminder function, a design function, an animation function, a reservoir function, and / or the like. Preferably, cleaning elements, display elements, a grip structure, or the like can be arranged on the functional surface. This allows, in particular, switching between different functions via the switching element, or at least one function to be activated. Preferably, a function can be assigned to each static state. Furthermore, a significantly higher level of user comfort can be provided.Furthermore, the cleaning result can be positively influenced.

[0045] It is further proposed that the functional unit comprises at least three mechanical switching elements, each made of an elastic material and each exhibiting at least two defined, static, and distinct states. Preferably, the functional unit can have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 switching elements, preferably 1 to 6 switching elements. In particular, it is possible to implement multiple switching elements, whereby the carrier body of the application unit and / or the handle unit need not have the same thickness throughout. The switching elements can have different shapes and / or sizes, such as length, width, and height. With multiple switching elements, the first equilibrium state, in particular the resting state, can differ on the oral hygiene product, for example, alternating.The resting state can be configured differently for various functions, particularly depending on the application. Preferably, the at least two or three mechanical switching elements are arranged side by side. More preferably, the switching elements are arranged in a row. Preferably, the switching elements are arranged one behind the other along the main direction of extension of the oral hygiene product. Alternatively, it would also be conceivable for the switching elements to be distributed, particularly evenly, across the application unit and / or the handle unit. The switching elements can form a regular and / or at least partially repeating structure. This allows for the provision of a particularly advantageous functional unit. In particular, a large functional area and / or a multitude of functions can be provided.Several toggle switches, each with a corresponding label or illustration, could be designed to be pressed after a defined cleaning process has been completed. For example, on (children's) toothbrushes, the toggle switches could serve as control elements. Three toggle switches, labeled or illustrated for morning, noon, and evening, could be used, with the switch pressed after cleaning at the corresponding time of day. Alternatively, four toggle switches could be used, each representing a quadrant of the teeth to be cleaned, similar to a quadrant timer. These switches could have labels and illustrations for quadrant 1, quadrant 2, quadrant 3, and quadrant 4.Furthermore, individual toggle switches or a combination of toggle switches can represent a predetermined usage period for the oral hygiene product. For example, three toggle switches can represent a usage period of three months, with one switch being toggled after each month. Alternatively, twelve toggle switches can be used to set the anticipated or recommended end of use, e.g., three months after initial use, as a reminder. The month in which the end of use is reached is then marked by the switched toggle switch.

[0046] In the case of multiple switching elements, these can be arranged in a row, for example, one behind the other, on a straight or curved line (e.g., on a circle or an ellipse), or freely. Furthermore, it would be conceivable for the switching elements to be arranged as an array, for example, with multiple switching elements side by side in two dimensions. The switching elements can be arranged at different distances from each other. Preferably, the distances in one or more dimensions are constant, and in particular, regular. In the case of multiple switching elements, the distances between the switching elements are measured, in particular, between the centers of the switching caps of the switching elements. Alternatively, the distances between the switching elements can vary. For example, it would be conceivable for the edge webs of the switching elements to be in contact with each other.Preferably, the distance is the sum of 0.5 * diameter of the first switching cap of the first switching element, the width of the support edge of the first switching element, the width of the edge web, the width of the support edge of the second switching element, and 0.5 * diameter of the second switching cap of the second switching element.

[0047] If the switching elements are arranged at different intervals, they can be designed identically with respect to the distance resulting from the width of the respective support edges and edge ribs. The distance varies between the respective centers of the switching caps.

[0048] With multiple switching elements, it is also possible for one switching element to be integrated within another. For example, a small switching element could be integrated into the switching cap of a larger switching element. Furthermore, different hardness levels can be combined within a single switching element, for instance, in the form of a softer switching cap and a harder switching cap (harder or softer is defined by the force [pressure force] required to switch the element). Additionally, one switching element can be oriented upwards, and another downwards. It is also conceivable that both switching elements are oriented upwards or downwards.

[0049] Furthermore, it is conceivable that at least one switching element does not have a closed outer contour. For example, the supporting rim of the switching element might not be arranged around the entire switching cap. In particular, a collar-like arrangement might be provided, for example, for placement within the application unit. Furthermore, the switching element could be positioned at the edge, for example, at the edge of the brush head, so that a complete enclosure is not possible. Additionally, switching elements could be designed for dual functions, such as a toothbrush with a tongue cleaner and / or soft element in one.

[0050] Furthermore, with multiple switching elements, it would be conceivable for the switching elements to be arranged in a three-dimensional geometry, i.e., not in a planar fashion. Preferably, the switching elements could be integrated in the form of a ball or a dome. In particular, it would be conceivable for the carrier body to also consist of a soft component, and for the carrier body and the switching elements to be formed in one piece. Preferably, the switching elements could protrude from a layer of the soft component of the carrier body. Such a design would be particularly conceivable if the switching elements were designed as play elements for a child's toothbrush. The carrier body with the switching elements could, for example, be arranged at a lower end of the oral hygiene product. Alternatively, it would also be conceivable for the entire handle unit to be designed with corresponding switching elements.This could, in particular, enable a reduction in the volume of the carrier body.

[0051] Furthermore, it is proposed that the functional unit has at least two mechanical switching elements, which share a common circumferential rim. With multiple switching elements positioned side by side, the rim can be geometrically extended. Additionally, the rim between two switching elements can be designed as a raised section made of the same material as the switching element(s). Thus, the edge of the support does not rest against the support body at all times.

[0052] It is further proposed that the handle unit comprises at least one handle base body, with the functional unit arranged on the handle base body. The handle base body, in particular, forms a support body for the handle unit to accommodate the functional unit. The functional unit can be arranged, in particular, either only in a defined partial area, such as a thumb grip area, of the handle base body, or distributed over the entire handle base body. For example, the functional unit can be arranged between a lower end of the oral hygiene product and the thumb grip area. In children's toothbrushes, the switching element of the functional unit can, for example, represent a Pop-it belly (e.g., the belly of an animal) if appropriately arranged. Preferably, the functional unit can be arranged in the area of ​​the palm rest.Alternatively, the functional unit could be arranged as a thumb grip within the thumb grip area. The functional unit could thus form a Pop-it thumb grip. Depending on the state of the switching element, the thumb grip can be protruding or recessed, and therefore have a dome at the front or rear. An operator can adapt the thumb grip area to their specific requirements. Advantageously, the grip unit comprises at least one thumb grip area and / or at least one hand grip area. The thumb grip area is advantageously located on the front of the oral hygiene product and, in particular, on the front of the grip element. It is conceivable that the thumb grip area and / or the hand grip area could have at least one element and / or a surface texture made of a soft component.This allows for the advantageous integration of additional functions on the handle unit, such as control and / or grip functions. The switching elements of the functional unit can be adjusted or positioned (e.g., in the thumb grip area or the application area) so that if excessive pressure is applied to the application unit during use, the switching element changes from its initial state to the deflected state. This alerts the user that they have applied too much force or pressure to the application unit and helps them learn to use the correct amount of pressure. The switching element can then be easily reset to its initial state.

[0053] Furthermore, it would also be conceivable that at least one switching element forms a suction cup. In particular, it would also be conceivable that two switching elements are provided, designed as opposing suction cups, which emit sounds when released, especially when disconnected.

[0054] Furthermore, it is proposed that the functional unit be completely enclosed by the handle body in at least one plane. This allows for a particularly advantageous integration of the functional unit. It also enables a more advantageous fastening of the functional unit and allows for a particularly slim and compact handle unit. Preferably, the handle body has at least one recess in which the functional unit, and in particular at least one switching element of the functional unit, is arranged. Preferably, the recess is completely enclosed by the material of the handle body in the main extension plane of the handle unit. Preferably, the handle body forms at least a partial ring, in particular a loop, which extends around the functional unit.Preferably, the recess is formed by an oval recess and / or a single or multiply convex recess. The base body, in particular, forms two lateral longitudinal ribs, each connected at at least one end, especially a front end and a rear end, and enclosing the recess and thus the functional unit. The recess may also have individual transverse ribs between the switching elements. The ring formed by the base body, in particular the loop, which encloses the recess, is preferably closed. It preferably has no open ends, such as forked shapes. The ring, in particular the loop, can have a wide variety of cross-sections.Possible cross-sectional shapes are circular, oval, elliptical, rectangular, rhomboid, triangular, n-sided, rhombus-shaped, and parallelogram-shaped, with the longitudinal edges / corners being rounded or sharp. The ring is particularly rounded or rounded on the outside, i.e., outside the recess. Furthermore, the cross-section can change along its length, transitioning from one shape to another, even multiple times. It is also conceivable that the handle body has several recesses, each containing at least one switching element of the functional unit. It is also conceivable that switching elements are arranged in only some of the recesses. Some of the recesses may, for example, simply have a frame and form a hole. The number of recesses can be, in particular, 1, 2, 3, 4, 5, or more, preferably one to three.The recesses can be arranged at least partially perpendicular to the longitudinal direction, side by side. The recess can have a wide variety of cross-sections when viewed from the front. The shape of the recess essentially corresponds to the shape of the functional unit.

[0055] Preferably, the carrier body has at least one recess. The carrier body can be part of the handle unit or part of the application unit. The carrier body has recesses or openings for the implementation of the switching element. The recesses form an edge for connecting the at least one switching element. A connection of an edge rib of the switching element is implemented in the recess. The recess preferably has a closed contour. Preferably, the recess does not have an angular contour. However, an angular contour with rounded corners would be conceivable, for example, an n-gon with rounded corners. Preferably, the recess has a round or rounded shape, such as a circle, oval, or oblong. For a single switching element, the recess has a diameter of 8 mm to 30 mm, preferably 12 mm to 25 mm.The length and / or width of the recess preferably corresponds substantially to its diameter. If the recess is designed to accommodate multiple switching elements, its length may differ. When multiple switching elements are arranged in a row, the width corresponds to the width of each individual switching element. The carrier body may, in particular, have a different thickness than the height of the switching element. Preferably, the switching element is completely recessed in the recess of the carrier body, for example, when arranged in a thumb grip recess. Alternatively, the switching element may protrude from the carrier body, in particular extending beyond an upper edge of the carrier body. The switching element may protrude sufficiently beyond the carrier body to allow for comfortable switching with a finger.The finger only needs to enter the recess in the carrier body minimally to actuate the switching element. Preferably, the at least one recess in the carrier body has a straight edge. The height of the recess is determined, in particular, by the fact that the switching element must be held in place on the carrier body, and therefore sufficient mounting surface must be available. The thickness of the carrier body can, however, be greater than the straight edge of the recess. The height of the edge of the recess is, in particular, from 3 mm to 15 mm, preferably from 5 mm to 10 mm. Preferably, the edge forms a surface, in particular an annular surface, which extends perpendicular to the longitudinal direction of the oral hygiene product. However, it would also be conceivable for the surface of the edge of the recess to be conically shaped.Furthermore, it would also be conceivable to provide steps in the surface of the recess's edge, whereby particular attention should be paid to the limitations of demolding in the injection mold. Not all recesses in the carrier body need to be equipped with a switching element or filled. In particular, it is also possible that at least some of the recesses are unfilled, that at least some of the recesses are only provided with a soft component at the edge, especially corresponding to the component of the switching element, that at least some of the recesses are completely filled, or that at least some of the recesses are filled with a material film.

[0056] Through the possible design variations in the interplay of the carrier body, the recess(s), the rim, the carrier edge, the switching cap, and / or the soft material, the switching element can become a movable component of an information element, a customizable surface texture, a figure, an ornament, a pictogram, or a logo. This can encourage the user to use the oral hygiene product in a playful way. Furthermore, it can increase user comfort. Additionally, it can optimize or reinforce the intended use of the oral hygiene product.

[0057] The recesses allow for material savings in the carrier body. Furthermore, additional material savings can be achieved by not completely filling the recesses. This makes the oral hygiene product more sustainable and resource-efficient. At least one switching element is specifically integrated into the recess in a form-fit and / or material-fit manner. Preferably, the switching element is also connected to the carrier body in a form-fit and / or material-fit manner.

[0058] Furthermore, it is proposed that the functional unit consists entirely of a soft component. Preferably, the at least one switching element consists entirely of a soft component. Preferably, the at least one switching element is arranged in a recess, in particular a cutout, of the application unit and / or the handle unit, wherein the switching element is at least partially enclosed laterally by the application unit and / or the handle unit. The switching noise or the switching force (pressure force) of the switching element of the functional unit depends on the hardness of the soft component. The harder the soft component, the louder the popping noise or the greater the force (pressure force) required to switch between the states.The compressive force is further influenced by the material thickness, the material itself, and the shape of the individual elements of the functional element, for example, the width of the support rim and the transition from the support rim to the switching cap. The compressive force required to move the switching element from its initial state to the deflected state is between 80 and 160 grams, preferably between 110 and 150 grams. To move the switching element back from the deflected state to the deflected state, a compressive force of 90 to 130 grams, preferably 60 to 140 grams, is required. A specific design that allows for rapid attainment of the new static state is particularly advantageous. Thermoplastic components are preferably used. TPEs or similarly soft materials are preferably employed. Alternatively, the use of silicone is also conceivable.When using silicone in series production, two processes must be combined, as the handle unit and / or the application unit are preferably manufactured using an injection molding process. This allows for the provision of a switching element that is particularly easy to manufacture and, in particular, a suitably durable switching element.

[0059] It is further proposed that the at least one switching element comprises at least one dome-shaped, in particular hemispherical, switching cap which is elastically deflectable. Preferably, the switching cap is dome-shaped, in particular hemispherical, at least in the first equilibrium state. More preferably, the switching cap is dome-shaped, in particular hemispherical, in both the first and second equilibrium states. The switching cap forms a dome in height. The switching cap has, in particular, a closed contour. The shape of the switching cap is, in particular, (hemi-)spherical or (hemi-)ellipsoidal. Alternatively, the shape of the switching cap can be hood-shaped, dome-shaped, conical, thimble-shaped, or pyramidal. Preferably, the shape is generally rounded. Preferably, the switching cap has a symmetrical basic shape, which is preferably not angular but round or oval.Preferably, the toggle cap has a rounded base shape (e.g., ellipse, circle, n-gon with rounded corners), particularly on one of its base faces. The base of the toggle cap can also follow a free contour (e.g., a figure-shaped one). A rounded base shape ensures the best functionality. Alternatively, an oval or regular n-gonal shape with strongly rounded corners would also be conceivable. Symmetrical shapes are particularly preferred. The toggle cap preferably forms only a part of the geometry of the switching element. For example, it is conceivable that the switching element is formed by a large rectangular element that has a round toggle cap somewhere along its length. Preferably, the toggle cap is connected via a rim. The rim can have a different width.Furthermore, the transition from the switching cap to the rim does not need to match the geometry of the recess in the handle unit and / or the application unit. This allows for a particularly advantageous switching element. In particular, an advantageous shape of the switching element can be achieved.

[0060] In one variant, the switching cap could have a non-closed layer or membrane, i.e., be provided with cutouts. Specifically, the switching cap could have incisions, particularly cuts towards the center, preferably spiral cuts in which the switching cap retains an overall dome or spherical shape, or sunray-shaped, straight cuts. The cuts are preferably regularly and / or symmetrically distributed. However, an irregular distribution is also conceivable. The number of cuts or cutouts is preferably 4 to 15, and more preferably 5 to 10. The width of the cuts or cutouts is preferably 0.5 mm to 3 mm, and more preferably 1 mm to 2 mm. With a corresponding design of the switching cap, the center can be either closed or open.A closed design of the center allows for particularly better reliability of the switching function. In an open center, the diameter of the opening is preferably between 0.5 mm and 5 mm, and more ideally between 1 mm and 2 mm.

[0061] Preferably, a surface structure is provided on the toggle cap of the at least one switching element. The toggle cap can preferably be provided with elements, particularly haptic, decorative, or informative elements, which protrude from the surface or are recessed. The height or depth of the elements is particularly from 0.1 mm to 1.5 mm, preferably from 0.3 mm to 1 mm. The structures can be distributed completely or partially over the toggle cap. Furthermore, the element can be completely filled or represented only by an outer contour. Possible examples of the elements, particularly decorative or informative elements, are ornaments, figures, and / or pictograms, such as Yes / No or On / Off, motifs, such as flowers or animals, and / or geometric elements, such as grids, diamonds, or studs.On the other hand, as already mentioned, information can be distributed across several switching caps, for example, morning / noon / evening or quadrant 1 / quadrant 2 / quadrant 3 / quadrant 4. An eroded surface texture, for example, is conceivable. The switching cap can have a different surface texture than other soft material zones on the oral hygiene product. In particular, the switching cap can have a different surface texture than the marginal ridge and / or the carrier rim.

[0062] It is further proposed that the at least one switching element has at least a partially circumferential rim for fixing the switching element, wherein the switching cap is connected to the rim via a support rim. Preferably, the rim is provided for direct connection to the handle unit and / or the application unit. The rim serves in particular to secure the switching element. Preferably, the rim extends around the switching element, with the rim being designed to connect to the switching cap. Preferably, the support rim is arranged between the switching cap and the rim, connecting the switching cap to the rim. The rim forms in particular part of the structure of the switching element or the functional unit. The rim ensures, in particular, the connection or attachment of the switching element to the handle unit and / or the application unit.Several implementations of the edge rib are conceivable, which would appear sensible to an expert. In particular, various shapes are possible. The edge rib can form a tactile element of the handle unit or blend into one.

[0063] In a first embodiment, the edge web can extend over the entire height of the recess in which the switching element is arranged. Alternatively, in a second embodiment, the edge web can extend only over the height / thickness of the support edge. Possibilities between the first and second embodiments are also conceivable. The edge web is particularly ring-shaped. Preferably, the edge web abuts directly to the support edge on the inside. The support edge is formed between the edge web and the switching cap. The support edge preferably abuts directly to the edge web on the outside, particularly around an outer circumference. Furthermore, the support edge preferably abuts directly to the switching cap on the inside, particularly around an inner circumference. The support edge is particularly ring-shaped. Most preferably, the support edge and the edge web are formed around the switching cap, particularly in a ring shape.Alternatively, the support rim and / or the rim web can form only a portion of the switching cap's circumference. The switching cap does not necessarily have to be 100% enclosed by the handle unit and / or the application unit, particularly by a support body of the handle unit and / or the application unit. The support rim must be designed to provide sufficient fixation of the switching cap to enable switching. For example, the support rim could provide multiple attachment points to the switching cap, separated by breaks. The number of attachment points or breaks is preferably 2 to 8, and more preferably 3 to 6. The support rim forms, in particular, partial ribs. The arrangement of these partial ribs can be regular or irregular. Preferably, however, the partial ribs are arranged symmetrically with respect to the center of the switching cap.This allows for a particularly advantageous, stable, and securely attached switching element. Specifically, it enables secure fixing of the switching element without negatively impacting the switching process. It is also possible for the recess to extend around the switching element, while the connection via the support edge does not completely encircle the switching cap. In this case, the support edge is interrupted in certain sections.

[0064] Furthermore, it is proposed that at least one switching element be formed in one piece. Preferably, the switching cap, the support rim, and the rim are formed in one piece or at least integrally from a single component. The switching element preferably consists of a soft component. The switching element is preferably manufactured using an injection molding process. This allows, in particular, the number of components to be kept to a minimum. Furthermore, it ensures reliable functionality of the switching element. The formation of the switching element can be carried out simultaneously and in one operation, preferably from the same injection point, with other soft material elements on the oral hygiene product, such as: Massage and / or cleaning elements on the application unit and / or tongue cleaning elements on the back of the application unit and / or haptic elements or holding zones on the handle unit and / or fastening elements such as a suction cup on the handle unit and / or elements that increase the flexibility of the handle unit or application unit in certain zones, formed by zones of soft material that fill recesses in the hard component of the handle or application unit and / or logos, figures, ornaments, decorative elements.

[0065] Furthermore, it is proposed that the functional unit comprises at least two mechanical switching elements which are integrally connected. If there are multiple switching elements, these can be arranged in a row, for example, one behind the other, along a straight or curved line, or freely. Preferably, the switching elements are arranged in a row. Preferably, the switching elements are arranged one behind the other along the main direction of extension of the oral hygiene product. The switching elements are designed to be directly adjacent to one another. This allows, in particular, the number of components to be kept to a minimum. Furthermore, the functionality of the switching element can be reliably ensured. This allows, in particular, a particularly advantageous functional unit to be provided. In particular, a large functional area and / or a multitude of functions can be provided.Several switching elements with a corresponding label and / or illustrations and / or arrangement may, for example, be intended to be pressed in after completion of a defined time, or usage or cleaning process.

[0066] It is further proposed that the handle base form a frame which directly and at least partially encloses the edge web. The frame, in particular, forms the support body. Preferably, the frame directly defines the recess provided for receiving the switching element. The frame can have connecting webs or a grid of connecting webs that define one or more switching elements. Preferably, the frame has an at least approximately constant cross-section. However, it would also be conceivable for the frame to have a changing cross-section. This would particularly advantageously allow for the provision of additional functions on the handle unit, such as control functions and / or grip functions.

[0067] It is further proposed that the handle body has at least one thumb grip area, wherein the at least one mechanical switching element is integrated into the thumb grip area or forms at least a part of it. The switching element in the thumb grip area is, in particular, completely enclosed by the handle body in at least one plane. Preferably, the functional unit is arranged as a thumb grip within the thumb grip area. The functional unit could accordingly form a pop-it thumb grip. Depending on the state of the switching element, the thumb grip can be projecting or recessed, and therefore designed with a dome at the rear or front. That is, the first equilibrium state or the functional surface can be oriented towards the front or the rear. An operator can, in particular, adapt the thumb grip area to their requirements.The switching element in the thumb grip area can serve to prevent excessive pressure on the application unit. In particular, the switching element can be adjusted so that it significantly changes its shape or even switches to a different position if excessive pressure is applied to the application unit. It is advantageous for the thumb grip area to be located on the front of the oral hygiene product and especially on the front of the grip element. This allows for the advantageous provision of additional functions on the grip unit, such as control functions and / or grip functions.

[0068] Alternatively or additionally, it would also be conceivable to arrange at least one switching element in the neck of the oral hygiene product, particularly in the neck of the application unit. However, it must be taken into account that switching will not work with standard toothbrush proportions, as the switching element cannot be made sufficiently large. Therefore, a generally or partially wider neck design than is commonly used is necessary. Here, too, the switching element can serve as an indicator if too much pressure is applied to the application unit.

[0069] Furthermore, it is proposed that the application unit comprises at least one brush head, wherein the functional unit is integrated into the brush head. Preferably, the functional unit comprises at least one switching element arranged on the brush head. The switching element is formed, in particular, by a convertible cleaning element and / or a reservoir and / or a protective cover. Preferably, the application unit comprises structural or cleaning elements mounted on the switching element. Preferably, the cleaning elements are injection-molded and, in particular, manufactured in one piece or in a single operation with the switching element. The switching element can have the function of pressure control, wherein the switching element, together with the cleaning elements, is pushed away when excessive pressure is applied and transitions into a second equilibrium state. Preferably, the switching element is integrated directly into the brush head.The switching element is recessed. For this purpose, it must be relatively large to allow switching between states. The cleaning elements on the switching element can be designed as bristles, lamellae, knobs, and / or surface structures. The lamellae can be formed, in particular, by cleaning elements designed as projecting ridges, especially with a wider extension compared to a bristle. The lamellae can, for example, provide a polishing or whitening effect. Alternatively, it is also conceivable that the switching element merely serves to control the contact pressure, as described above, and has no other function. This allows for the advantageous provision of additional functions on the application unit, such as control functions and / or a cleaning function.

[0070] Preferably, the switching element is designed as a functional element in the brush head. Preferably, the switching element can be formed by a switchable, and in particular, a foldable, collar. The switching element can, in particular, form a combination of a switching head housing or protective element and a switching tongue cleaner or tongue cleaner edge. When folded up, the switching element can serve as a head housing or protective element for the bristles, at least partially surrounding a bristle field of the brush head. When folded down, the switching element or its edge can serve as a tongue cleaner, while the bristle field is exposed. The switching element is, in particular, formed by a U-shaped wall that extends around an upper edge of the brush head.An upper free edge of the wall can point towards the front in a first equilibrium state or towards the back of the oral hygiene product in a second equilibrium state. Alternatively, a combination of a switchable cleaning element and a switchable tongue cleaner is also conceivable. In this case, the switchable element can form a cleaning element when flipped up and a tongue cleaner when flipped down. Alternatively, a combination of a switchable massage element and a switchable tongue cleaner is also conceivable. In this case, the switchable element can form a massage element when flipped up and a tongue cleaner when flipped down. Additional structures can be attached to the edge or surface of the switchable element. These structures serve primarily to support cleaning, for example, tongue cleaning in one case and / or tooth cleaning in the other.A free edge of the switching element can have various designs that a person skilled in the art would consider useful, such as being continuously or continuously wavy rather than straight, with bumps on the edge, and / or with small bristles on the edge. The side surfaces of the switching element could be provided with recesses, such as blind holes or through holes, and / or with bumps. Alternatively or additionally, the switching element can have a structure, such as a grid, bump, or EDM pattern.

[0071] Furthermore, it is proposed that the at least one switching element has a substantial functional surface, on which cleaning elements are arranged. Preferably, the cleaning elements are injection-molded and, in particular, manufactured as a single casting with the switching element. It is further proposed that the at least one switching element has cleaning elements such as (injected) bristles and / or lamellae and / or knobs and / or surface structures, wherein the cleaning elements are formed integrally with a switching cap of the switching element. Advantageously, "integrally" can also be understood as "one piece." The cleaning elements are, in particular, formed integrally with the at least one switching element. Preferably, the functional surface is dome-shaped, in particular hemispherical, in the first equilibrium state and bowl-shaped in the second equilibrium state.The functional surface is formed, in particular, by the upper surface of the switching cap of the switching element. Preferably, the functional surface is arranged on a front surface of the oral hygiene product, especially on a front surface of the application unit. More preferably, the functional surface is formed by a surface of the switching cap of the switching element facing the front. The cleaning elements are arranged to project from the functional surface. This allows, particularly advantageously, additional functions to be provided on the application unit, such as control functions and / or cleaning functions. It is further proposed that the cleaning elements form different cleaning patterns depending on the state of the switching element. Preferably, the switching element has the function that the cleaning area of ​​the application unit is partially customizable.Thus, in the first equilibrium state, the switching element can, for example, form a differently shaped cleaning field than in the second equilibrium state. Depending on the state of the switching element, not every function is active in every state. Preferably, a cleaning subfield can be activated by means of the switching element. This allows for a particularly advantageous degree of customizability. Advantageous adaptability can be provided.

[0072] Furthermore, it is conceivable that the oral hygiene product is formed by a convertible tongue cleaner, with the application unit being a tongue cleaner head. Preferably, in a corresponding embodiment, the at least one switching element is arranged at least on the application unit. Preferably, cleaning elements, in particular tongue cleaning elements, of the application unit are arranged on the at least one switching element. It is particularly intended that the cleaning elements are pushed away if too much pressure is applied. Preferably, the at least one switching element is equipped with the cleaning elements and / or forms at least a portion of itself as a cleaning element. Preferably, a corresponding oral hygiene product can have convertible tongue cleaner designs.In particular, a design with low pressure, in which the switching elements are not pushed away from the cleaning elements, and a design with pushed-away switching elements, in which the base of the application unit, especially the tongue cleaner head which carries the switching elements, serves as a cleaning surface. Preferably, the cleaning surface of the tongue cleaner head has additional cleaning elements. In the second design, cleaning is carried out accordingly with the additional cleaning elements, or certain cleaning elements are more readily accessible in the second design. Alternatively, it would also be conceivable that the tongue cleaner head has two sides with two different tongue cleaners per side. In this case, it would be particularly conceivable that the switching elements of the front or the back could be activated. In particular, the front and back of the tongue cleaner head could each have two different designs.The application unit can perform various functions. Corresponding configurations of the application unit are possible, in particular, as either a dedicated tongue cleaner or a tongue cleaner integrated into a toothbrush. This means that bristles for tooth cleaning are available on the front of the application unit, and the described tongue cleaner head is located on the back. Preferably, the switching element is free at the rear so that it can be pushed back into place. A design as a dedicated tongue cleaner is particularly advantageous in this respect.

[0073] The switching element may have no function or a different function on the front of the application unit than on the back of the application unit, and vice versa.

[0074] Furthermore, it is possible that the at least one switching element is not accessible from both sides. In this case, the at least one switching element, on the rear side, particularly defines a cavity. Preferably, the functional unit in this case includes a return element for the at least one switching element, which serves as a return aid. The return element can, for example, be formed by a pull element arranged on the switching element to retract the switching element into the first equilibrium state. The return element can, for example, also be formed by a cleaning element. Alternatively or additionally, it would also be conceivable for the return element to be formed by a push element. The return element can, for example, be formed by a rocker that presses on the switching element in the second equilibrium state, thus triggering the return.Alternatively or additionally, it would also be conceivable that the cavity defined by the switching element has an inlet opening into which, for example, an operator could blow to move the switching element from the second equilibrium state to the first equilibrium state. Alternatively, it would also be conceivable that several switching elements define a common, closed cavity, with a volume of the cavity dimensioned such that only a defined number of switching elements can be in the first or second equilibrium state at any one time. Thus, when a switching element is moved from one equilibrium state to the other, a pressure equalization within the cavity automatically moves another switching element from the second equilibrium state to the other equilibrium state.For example, two switching elements can be connected via a closed cavity, the volume of which is designed so that the switching elements can never be in the same equilibrium state.

[0075] Possible application examples for switching elements that are not accessible from both sides include application units with a brush head featuring a tongue cleaner, particularly on the back. Furthermore, an application unit designed as a toothbrush head with an AFT bristle field would also be conceivable. Due to the bristle field on the front, the switching element is only accessible from one side. Alternatively or additionally, an application is conceivable in which the switching element is located in the handle base and covers a cavity. Reset could be achieved with a reset element, particularly a pull or push element.

[0076] It is further proposed that the switching cap of the at least one switching element has a diameter of 8 mm to 30 mm. Preferably, the switching cap, particularly when measured on the rest position side at the transition to the edge rib, has a diameter of 8 mm to 30 mm, more preferably 12 mm to 25 mm. Similarly, the length and width of the switching cap are preferably also 8 mm to 30 mm, more preferably 12 mm to 25 mm. This allows for a particularly compact and yet easy-to-use switching cap.

[0077] Furthermore, it is proposed that the switching cap of the at least one switching element has a material thickness of 0.5 mm to 2.5 mm. Preferably, the material thickness of the switching cap is 0.8 mm to 2 mm. A layered design would also be possible. Preferably, however, the switching cap has a substantially constant layer thickness. The greatest material thickness is preferably at a high point of the switching cap, with a reduced material thickness in the area of ​​the rim to facilitate switching. In this context, "substantially" is understood to mean, in particular, that a deviation from a predetermined value is less than 25%, preferably less than 10%, and most preferably less than 5% of the predetermined value. This allows for the provision of a particularly advantageous switching cap.It can be particularly advantageous to enable simple switching of the switching element between the states.

[0078] Furthermore, it is proposed that the support rim of the at least one switching element has a width of 0.5 mm to 5 mm. Preferably, the minimum distance between the switching cap and the rim is 0.5 mm to 5 mm, more preferably 0.7 mm to 3 mm. Preferably, the support rim has a thickness of 0.5 mm to 3 mm, more preferably 0.7 mm to 1.5 mm. This allows for a particularly advantageous support rim. It also makes switching the switching element between states particularly easy.

[0079] In one embodiment, the oral hygiene product could be formed by a hairbrush or a massage brush, with the switching element located in the application unit or the handle unit. In the application unit, the function of the switching element could be analogous to that of a tongue cleaner.

[0080] Preferably, the functional unit can be used in its basic function even beyond the lifespan of the oral hygiene product. In particular, the functional unit can be reused or reused after its initial use in the first oral hygiene product. For example, if the oral hygiene product is designed as a replaceable-head toothbrush, the handle unit with the functional unit can be reused multiple times. Alternatively or additionally, it would also be conceivable that the functional unit could be detached. By detaching the functional unit, it can be reused, for example, as a key ring. In particular, a hole in the carrier element without a switching element could be used as an eyelet for a key ring. Detachment can generally be achieved, for example, by sawing, cutting, or snapping.

[0081] Furthermore, it is proposed that the functional unit includes a material reservoir. Preferably, the switching cap of the switching element in its original form has a filling in the recess formed by the switching cap. Preferably, the filling can be dispensed by switching the switching element. The filling can, for example, consist of toothpaste. The switching element can, in particular, serve as a temporary reservoir or as a measuring or dosing unit. In this case, the switching element is, in particular, dispensed and then filled with treatment, or it is filled with treatment and then dispensed, such as bleaching or dental gel. When the oral hygiene product is used, the filling is dispensed. Once the application is complete, the switching element can be folded back in. The switching cap can thus function as a reservoir.When used as intended, both the front and back of the application unit (or handle unit) can be flipped to form a concave surface on either side, depending on its position. This surface can be used to hold a liquid, paste, tablet, gel bead, or similar substance. This allows the user to perform a (special) treatment regularly (e.g., daily, weekly) or occasionally. Examples of such treatments include whitening, antibacterial, and fluoride treatments. If no (special) treatment is desired, the flip cap can be flipped to the other side, and the application unit can be used without the reservoir function.

[0082] Furthermore, this method makes it possible to utilize the reservoir function for different treatments depending on the condition. For example, with an oral hygiene tool like a toothbrush, the concave side facing the front is used for treating the teeth, while the concave side facing the back is used for treating the tongue.

[0083] Furthermore, the invention relates to a protective cap for an oral hygiene product, in particular for a toothbrush, comprising at least one, advantageously one-piece, cap body that defines at least one interior space designed to receive at least one part, preferably at least one part of an application unit, of the oral hygiene product. The protective cap is in particular formed by a head holder. It is proposed that the protective cap has at least one, in particular one-piece, mechanical switching element fixedly arranged on the cap body, which is made of an elastic material and has at least two defined, static, and distinct states. The cap body may have a suspension point. The cap body in particular comprises two shell elements which are pivotably connected to one another. Preferably, a switching element is arranged on each of the shell elements.The protective cap is primarily case-shaped. In one version, the switching element changes position when the protective cap is closed, for example, from the inside to the outside. It would be conceivable that the protective cap could be reopened by pressing in at least one of the switching elements. In another version, the switching element is specifically designed to clamp an application unit of the oral hygiene product. It would be conceivable that the switching element does not change position when the head case is closed, but instead clamps the application unit before the switching point. This allows the inserted oral hygiene product and the protective cap to be advantageously fixed together.

[0084] The design of the protective cap according to the invention allows for advantageous properties with regard to secure and / or hygienic fastening and / or storage. Furthermore, the switching element can be used, in particular, for the reliable opening of the protective cap. In addition, a dual functionality can advantageously be achieved, encompassing secure enclosing as well as an additional function.

[0085] The protective cap is designed to protect and / or at least partially enclose the application unit, particularly the cleaning area. Preferably, the protective cap is designed as a toothbrush cap. Specifically, the protective cap is intended for use with at least one manual toothbrush and / or at least one electric toothbrush. Advantageously, the protective cap has at least one opening through which, when placed on the oral hygiene product, a neck area of ​​the application unit penetrates the interior. In particular, the opening is dimensioned such that the cleaning area located inside cannot be removed from the interior through it. Specifically, the cap body is designed to be opened for placement on the cleaning area.Preferably, the entire cleaning area, and in particular its bristles and / or bristle bundles, is arranged within the interior when attached. Preferably, the protective cap is formed in one piece. In particular, the cap body forms the protective cap. The cap body has a length of at least 20 mm, advantageously at least 30 mm, and particularly advantageously at least 40 mm and / or at most 60 mm, measured without the hanger. The cap body has a width of at least 10 mm, advantageously at least 15 mm, and particularly advantageously at least 20 mm and / or at most 50 mm, advantageously at most 40 mm, and particularly advantageously at most 30 mm.In particular, the cap body has a height of at least 10 mm, advantageously at least 15 mm, and particularly advantageously at least 20 mm, and / or at most 50 mm, advantageously at most 40 mm, and particularly advantageously at most 30 mm. Furthermore, the cap body has a wall thickness that is advantageously at least substantially constant, of at least 0.3 mm, advantageously at least 0.5 mm, and particularly advantageously at least 0.7 mm, and / or at most 2.5 mm, advantageously at most 2 mm, and particularly advantageously at most 1.3 mm.

[0086] Advantageously, the cap body has at least one ventilation hole. Particularly advantageously, the cap body has several ventilation holes, especially those arranged in pairs that are mirror-symmetrical to each other and / or regularly spaced. Advantageously, at least some of the ventilation holes are designed such that they together form a cap motif, such as a stylized face or at least parts thereof, or some other pattern. Preferably, the ventilation holes are arranged laterally on the cap body. Advantageously, the cap body has a smooth surface, particularly for reasons of improved hygiene and / or reduced susceptibility to soiling, although surface texturing is also conceivable, at least in sections, which can form parts of the cap motif.

[0087] The cap body is advantageously made of any hard component, but preferably of polypropylene or polyethylene. It is also conceivable that the cap body is at least partially made of a soft component, preferably TPE. In particular, the cap body is formed as an injection-molded part. Furthermore, it is conceivable that the cap body material comprises at least one additive with functional properties, for example, antibacterial agents. Additives for optical reasons, such as glitter and / or colored microparticles or the like, are also conceivable.

[0088] The hanger is advantageously hook-shaped. In particular, the hanger is curved towards the point where it passes through the cap body. Advantageously, the hanger is U-shaped. Furthermore, the hanger advantageously has a cross-section that tapers towards its end. Additionally, the hanger is advantageously tapered. Preferably, the hanger is designed as a hollow body, the interior of which can be connected to the interior of the cap body. It is also conceivable that the hanger has at least one bearing section made of a soft component on at least one inner surface, which is intended to rest against a suspension point such as a hook and / or a rod or the like. However, other hanger designs are also conceivable. For example, the hanger could be a magnetic hanger, a hook-and-loop hanger, a suction cup hanger, or the like.Furthermore, it is conceivable that the hanger is intended for attachment to a counter element, which can be mounted at a suspension position and, in particular, forms a suspension system together with the hanger.

[0089] Advantageously, the shell elements are connected to one another by means of at least one, and in particular exactly one, film hinge. However, a combination of several film hinges arranged side by side, and in particular spaced apart, is also conceivable. The film hinge is arranged, in particular, on the back of the cap body. In particular, the film hinge has a material thickness of at least 0.05 mm, advantageously at least 0.1 mm, and particularly advantageously at least 0.15 mm and / or at most 0.7 mm, advantageously at most 0.5 mm, and particularly advantageously at most 0.3 mm. Preferably, the material thickness of the film hinge varies and is advantageously about 0.28 mm in an edge region and / or about 0.2 mm in a central region, which is not necessarily arranged in the middle.

[0090] Preferably, the cap body can be manufactured and / or produced using a simple tool without core pulls, etc., in particular by means of at least one injection molding process. Preferably, the cap body is manufactured in an open state in which the shell elements preferably enclose an opening angle of 180°. In particular, the cap body, in the open state, is demoldable in at least one direction, advantageously in two opposite directions, and / or is free of an undercut, at least apart from the closing elements of the closure unit.

[0091] The soft component for manufacturing the functional unit or switching element is preferably introduced from a injection point. The injection point is preferably located in an end region of the functional element where the switching element has a larger accumulation of material mass, and thus in the edge region of the switching element. This is the case, for example, with multiple switching elements, with the injection point located in the edge region of the largest switching element at the end. It may be necessary to create a material buffer of soft component in the area of ​​the injection point to ensure optimal material flow.

[0092] Venting may be necessary in the cavity used to manufacture the switching element in the tool to ensure optimal filling of the switching cap with the soft component. This venting can occur via incorporated structures / logos / geometries on the switching cap or via elements specifically designed for this purpose. These venting elements are preferably located at the culmination point of the individual switching cap.

[0093] Advantageous properties regarding hygienic and / or safe storage can be achieved in particular with a system comprising at least one oral hygiene product according to the invention and at least one protective cap according to the invention. In particular, the system comprises exactly one oral hygiene product and exactly one protective cap, in particular one placed on top of it. Advantageously, the oral hygiene product can be suspended by means of the hanger when the protective cap is in place, in particular without its cleaning area falling out of the interior.

[0094] Furthermore, the invention comprises a method for producing an oral hygiene product and / or a protective cap and / or a system according to the invention. In particular, the method can include at least one step in which the protective cap is placed on the oral hygiene product and advantageously closed, and preferably at least one step in which the oral hygiene product is suspended by means of the suspension device of the attached protective cap, for example, on a hook, a screw, a nail, a bracket, or the like. It is also conceivable that the method includes at least one step in which at least a part of the oral hygiene product and / or the protective cap is produced by at least one injection molding process and / or by at least one bristle application process, with particular reference in this regard to the description above.

[0095] The oral hygiene product and the protective cap according to the invention are not to be limited to the applications and embodiments described above. In particular, the oral hygiene product and the protective cap according to the invention may, to fulfill a function described herein, comprise a different number of individual elements, components, and units and / or any meaningful combination thereof. Furthermore, values ​​within the specified limits of the value ranges stated in this disclosure shall also be considered disclosed and freely usable. Drawings

Description of the exemplary implementations

[0098] The Figure 1Figure 46a shows a schematic perspective view of the front of an oral hygiene product 10a. In this case, the oral hygiene product 10a is designed as a toothbrush, specifically a children's toothbrush. The oral hygiene product 10a can also be a disposable toothbrush or a toothbrush with replaceable heads. Furthermore, the oral hygiene product 10a could be a flosser, a single-tuft brush, an interdental cleaner, a tongue cleaner, or the like. Combined oral hygiene products are also conceivable, which combine at least two different functions, for example, a toothbrush with a tongue cleaner, a toothbrush with massage elements, an interdental cleaner with a flosser, or similar products.

[0099] The oral hygiene product 10a has at least one application unit 12a. Furthermore, the oral hygiene product 10a has at least one handle unit 14a. The handle unit 14a consists of a hard component and, optionally, a soft component. In general, a design with one or more hard components and / or one or more soft components is also possible. The soft component is necessary in any case for the implementation of a functional unit.

[0100] The following will refer to the Figures 1 to 11 Reference is made to figures 10a, which show different views of the oral hygiene product. Due to these differing views, some elements are not depicted in all figures and are therefore not labeled with reference symbols in all figures.

[0101] The oral hygiene product 10a has a longitudinal axis 48a, a vertical axis 50a, and a horizontal axis 52a. The longitudinal axis 48a is parallel to a principal extension direction 54a of the oral hygiene product 10a. When the oral hygiene product 10a is placed with a back side 56a on a flat surface, such that the longitudinal axis 48a is parallel to the surface, the vertical axis 50a is perpendicular to the longitudinal axis 48a and perpendicular to the surface and the horizontal axis 52a. The horizontal axis 52a is perpendicular to the longitudinal axis 48a and perpendicular to the vertical axis 50a.

[0102] The at least one application unit 12a has a head region 58a. The head region 58a forms a brush head 34a of the application unit 12a. In the present case, the head region 58a, in particular the brush head 34a, is designed as a toothbrush head. The brush head 34a has, in particular, a base body 60a designed as a bristle carrier. The base body 60a of the brush head 34a is formed entirely from a hard component. However, it would also be conceivable that the base body 60a of the brush head 34a is formed from a hard component and a soft component. The base body 60a of the brush head 34a forms a bristle carrier. The oral hygiene product 10a further has a cleaning area 62a received by the brush head 34a, which comprises a plurality of bristle bundles. At least one recess is formed on the front of the brush head 34a.At least one recess is provided for receiving a bundle of bristles from the cleaning area 62a. The brush head 34a has a plurality of recesses. The recesses are formed by bristle holes. The recesses are shaped as blind holes. The recesses have a diameter of 1.2 mm to 2 mm in the main area and preferably 1.4 mm to 1.8 mm. Preferably, the recesses have a chamfer at the entrance. The chamfer is in particular designed as a cone or rounded edge. Furthermore, the recesses are in particular tapered at the lower end. In principle, the recesses can also be designed differently. Any suitable bristles are suitable, which, as described above, can be punched, for example, using the anchor punching method. The structure of the head area 58a differs in other bristle-fitting methods.In principle, the use of other bristle-bearing methods would also be conceivable, for example, the anchorless AFT method. This would allow for the provision of an anchorless oral hygiene product 10a. In the case of AFT, a recess is provided in the brush head 34a, which is designed to receive a plate parallel to the handle unit 14a. The plate is manufactured, in particular, by means of an injection molding process, whereby the plate is already bristle-bearing before attachment. The plate is designed to be anchored in the recess of the brush head 34a, in particular by welding. Bristle bundles can differ with regard to their length, composition, number of bristles, bristle material, color, surface texture, and the like.Similarly, the angles at which the bristles and / or bristle bundles are arranged relative to each other or to a surface of the base body 60a of the brush head 34a can vary between bristles and / or between bristle bundles. Furthermore, the application unit 12a in this case comprises at least one neck region 64a, which in particular connects the head region 58a with the handle unit 14a. The neck region 64a forms a neck.

[0103] The application unit 12a is arranged on the upper surface of the oral hygiene product 10a. The application unit 12a forms the uppermost point of the oral hygiene product 10a. The application unit 12a is made entirely of a hard component. However, it would also be conceivable for the application unit 12a to be made partly of a soft component and partly of a hard component. For suitable soft and / or hard components, reference is made to the description above. In principle, the application unit 12a can have at least one tongue cleaner element. The tongue cleaner element can, in particular, have nubs and / or lamellae. Preferably, the tongue cleaner element is arranged on the back of the head region 58a; in particular, it can be arranged on a ring made of a soft component and / or on an island made of a hard component.

[0104] The neck section 64a forms a transition between the application unit 12a and the handle unit 14a. The neck section 64a is made of the hard component. The neck section 64a is at least partially spring-loaded.

[0105] The handle unit 14a has a handle base body 22a. The handle unit 14a has at least one grip surface 66a, which forms a surface of the handle base body 22a. The grip surface 66a extends on the front 46a from the neck area 64a to the lower end of the oral hygiene product 10a on the underside. The handle base body 22a of the handle unit 14a defines at least one recess 68a. The recess 68a extends completely through the handle base body 22a and is completely enclosed by the handle base body 22a in at least one plane 24a. The recess 68a is completely enclosed by the handle base body 22a in a plane 24a parallel to a principal extension plane of the handle unit 14a. The recess 68a is completely enclosed by the handle base body 22a in the main extension plane of the handle unit 14a. The handle base body 22a forms a frame that extends around the recess 68a.The recess 68a has a multiply convex cross-sectional shape in the main plane of extension of the handle unit 14a. The recess 68a is specifically aligned along the longitudinal axis 48a of the oral hygiene product 10a. The handle base 22a forms two lateral longitudinal ribs 70a, 70a', which are connected at the front and rear ends of the recess 68a along the longitudinal axis 48a and enclose the recess 68a. The frame formed by the handle base 22a is closed. In particular, there are no open ends, such as forked shapes. The longitudinal ribs 70a, 70a' of the handle base 22a are connected to each other at a lower end of the oral hygiene product 10a and at a transition from the handle unit 14a to the neck area 64a. The longitudinal webs 70a, 70a' of the handle body 22a have, by way of example, a D-shaped cross-section.The longitudinal ribs 70a, 70a' of the handle body 22a are rounded or rounded on the outside, i.e., outside the recess 68a. Furthermore, the longitudinal ribs 70a, 70a' of the handle body 22a are approximately straight on the inside, i.e., facing the recess 68a, and in particular have a surface perpendicular to the main plane of extension of the oral hygiene product 10a. The cross-sections of the longitudinal ribs 70a, 70a' can change, at least partially, along their length, particularly with regard to the dimensions of the cross-section. The longitudinal ribs 70a, 70a' of the handle body 22a have a wavy, in particular a semi-wavy, shape along the longitudinal axis 48a.

[0106] Furthermore, the oral hygiene product 10a has a functional unit 16a, which is arranged on the handle unit 14a. The functional unit 16a can have various functions, such as a cleaning function, a comfort function, in particular a gripping function, a handling function, and / or an activity function. The functional unit 16a functionally forms part of the handle unit 14a. The functional unit 16a is fixedly, in particular captive, arranged on the handle unit 14a. The functional unit 16a is arranged on the handle base body 22a. The functional unit 16a is completely enclosed by the handle base body 22a in at least one plane 24a. The functional unit 16a is arranged in the recess 68a. The functional unit 16a at least partially fills the recess 68a. The functional unit 16a is completely enclosed by the material handle body 22a in the main extension plane of the handle unit 14a.The functional unit 16a forms at least a portion of a grip surface 66a of the grip unit 14a. The functional unit 16a consists entirely of a soft component.

[0107] Functional unit 16a comprises at least one one-piece mechanical switching element 18a, 18a', 18a", 18a‴, 18a"", which is made of an elastic material and has at least two defined static states that are distinct from one another. Functional unit 16a comprises at least three mechanical switching elements 18a, 18a', 18a", 18a‴, 18a"", each made of an elastic material and each having at least two defined static states that are distinct from one another. Functional unit 16a comprises, by way of example, exactly five mechanical switching elements 18a, 18a', 18a", 18a‴, 18a"", each made of an elastic material and each having at least two defined static states that are distinct from one another.The functional unit 16a comprises a first switching element 18a, a second switching element 18a', a third switching element 18a', a fourth switching element 18a‴, and a fifth switching element 18a"". In a direction from a lower end of the oral hygiene product 10a towards the application unit 12a, the first switching element 18a is arranged first, followed by the second switching element 18a', then the third switching element 18a", followed by the fourth switching element 18a‴, and then the fifth switching element 18a"". The switching elements 18a, 18a', 18a", 18a‴, and 18a"" each have exactly two defined static states that are distinct from one another: a first equilibrium state, in particular an initial state, and a second equilibrium state, in particular a deflection state. In the . Figures 1 to 7 All switching elements 18a, 18a', 18a", 18a‴, 18a"" are in the first equilibrium state. In the Figures 8 to 11The first switching element 18a is in the second equilibrium state, while the second to fifth switching elements 18a', 18a", 18a‴, 18a"" are in the first equilibrium state. The first equilibrium state represents a rest state for the respective switching element 18a, 18a', 18a", 18a‴, 18a"". The first equilibrium state represents an unloaded state. Furthermore, the switching elements 18a, 18a', 18a", 18a‴, 18a"" are at least partially pre-tensioned in the second equilibrium state, in particular the deflection state. The switching elements 18a, 18a', 18a", 18a‴, 18a"" can be manually moved by an operator, in particular by applying a pressure force to the respective switching element 18a, 18a', 18a", 18a‴, 18a"" from one equilibrium state to another.From an intermediate position between the equilibrium states, the switching elements 18a, 18a', 18a", 18a‴, 18a"" always switch to one or the other equilibrium state, depending on the intermediate position. In particular, the switching element 18a, 18a', 18a", 18a‴, 18a"" automatically switches to the static state when approaching it. The equilibrium states are, in particular, a rest position or a balanced position. The switching elements 18a, 18a', 18a", 18a‴, 18a"" each have a function for the actual application of the oral hygiene product 10a and / or an additional function. For example, the switching elements 18a, 18a', 18a", 18a‴, 18a"" can create a play element, for example, for a child's toothbrush. Alternatively, the function of the switching elements 18a, 18a', 18a", 18a‴, 18a"" can be intended for a non-play application, e.g., as a clamping element, control element, or the like.The switching elements 18a, 18a', 18a", 18a‴, 18a"" serve in particular as game elements and / or as control elements. The switching elements 18a, 18a', 18a", 18a‴, 18a"" each have a significant functional surface 20a, which is convexly curved in the first equilibrium state and concavely curved in the second equilibrium state. The functional surfaces 20a of the switching elements 18a, 18a', 18a", 18a‴, 18a"" are dome-shaped, in particular hemispherical, in the first equilibrium state and bowl-shaped in the second equilibrium state. In the second equilibrium state, the switching elements 18a, 18a', 18a", 18a‴, 18a"" are each convexly curved towards a front side in the first equilibrium state and convexly curved towards a back side in the second equilibrium state.The functional surfaces 20a of the switching elements 18a, 18a', 18a", 18a‴, 18a"" are each formed by a top surface of a switching cap 26a, 26a', 26a", 26a‴, 26a"" of the respective switching element 18a, 18a', 18a", 18a‴, 18a"". The functional surfaces 20a are each arranged on the front surface 46a of the oral hygiene product 10a. The functional surfaces 20a may, for example, have a label (not shown in further detail). Several switching elements 18a, 18a', 18a", 18a‴, 18a"" with a corresponding label or illustration may, for example, be designed to be pressed in after completion of a defined cleaning process. For children's toothbrushes, for example, it would be conceivable that the switching elements 18a, 18a', 18a", 18a‴, 18a"" are provided as control elements.For example, switching elements 18a, 18a', 18a", 18a‴, 18a"" are conceivable, each labeled or illustrated with morning, noon, and evening symbols, and the corresponding switching element 18a, 18a', 18a", 18a‴, 18a"" could be pressed in after cleaning at the appropriate time of day. Alternatively, switching elements 18a, 18a', 18a", 18a‴, 18a"" are conceivable, each representing a quadrant to be cleaned, analogous to a quadrant timer. The switching elements 18a, 18a', 18a", 18a‴, 18a"" could accordingly have labels and illustrations for quadrant 1, quadrant 2, quadrant 3, and quadrant 4.

[0108] The switching elements 18a, 18a', 18a", 18a‴, 18a"" each have a dome-shaped, in particular hemispherical, switching cap 26a, 26a', 26a‴, 26a"" which is elastically deflectable. The switching caps 26a, 26a', 26a", 26a‴, 26a"" are each dome-shaped, in particular hemispherical, in the first equilibrium state. The switching caps 26a, 26a', 26a", 26a‴, 26a"" are each dome-shaped, in particular hemispherical, in the first equilibrium state and in the second equilibrium state. The switching caps 26a, 26a', 26a", 26a‴, 26a"" each form a dome along the vertical axis 50a. The switching caps 26a, 26a', 26a", 26a‴, 26a"" each have a closed contour. The shape of the switching caps 26a, 26a', 26a", 26a‴, 26a"" is spherical. The switching caps 26a, 26a', 26a", 26a‴, 26a"" each form at least a substantial hemisphere. The switching caps 26a, 26a', 26a", 26a‴, 26a"" also have a symmetrical, round base shape.The switching caps 26a, 26a', 26a", 26a‴, 26a"" are each convexly curved towards a front side in the first equilibrium state and convexly curved towards a rear side in the second equilibrium state. The switching caps 26a, 26a', 26a", 26a‴, 26a"" of the switching elements 18a, 18a', 18a", 18a‴, 18a"" have a diameter of 8 mm to 30 mm. Preferably, the switching caps 26a, 26a', 26a", 26a‴, 26a"", measured particularly on the side of the rest position, at the transition into a rim 28a, each have a diameter of 8 mm to 30 mm, preferably 12 mm to 25 mm. Preferably, the length and width of the switching caps 26a, 26a', 26a", 26a‴, 26a"" are each from 8 mm to 30 mm, preferably from 12 mm to 25 mm. Furthermore, the switching caps 26a, 26a', 26a", 26a‴, 26a"" of the switching elements 18a, 18a', 18a", 18a‴, 18a"" each have a material thickness of 0.5 mm to 2 mm.The material thickness of the switching caps 26a, 26a', 26a", 26a‴, 26a"" is preferably from 0.8 mm to 2.5 mm. The switching caps 26a, 26a', 26a", 26a‴, 26a"" each have a substantially constant layer thickness. The greatest material thickness is preferably at a high point of the respective switching cap 26a, 26a', 26a", 26a‴, 26a"", while the material thickness in the region of the rim 28a is reduced to allow switching. The switching elements 18a, 18a', 18a", 18a‴, 18a"" are designed as "pop it" or "push pop" devices. The switching caps 26a, 26a', 26a", 26a‴, 26a"" are designed as individual "Pop it" or "Push pop" bulges.

[0109] Furthermore, the switching elements 18a, 18a', 18a", 18a‴, 18a"" each have at least one at least partially circumferential rim 28a for fixing the switching element 18a, 18a', 18a", 18a‴, 18a"", wherein the switching cap 26a, 26a', 26a", 26a‴, 26a"" is connected to the rim 28a via a support rim 30a, 30a', 30a", 30a‴, 30a""". The rims 28a are designed for direct connection to the handle unit 14a. The edge ribs 28a serve to fasten the switching elements 18a, 18a', 18a", 18a‴, 18a"". The edge ribs 28a each extend around the respective switching cap 26a, 26a', 26a", 26a‴, 26a"" of the respective switching element 18a, 18a', 18a", 18a‴, 18a"", wherein the edge rib 28a of a switching element 18a, 18a', 18a", 18a‴, 18a"" corresponds to the switching cap 26a, 26a', 26a", 26a‴, 26a"" of the corresponding switching element 18a, 18a', 18a", 18a‴, 18a"" is criticized.Between the switching caps 26a, 26a', 26a", 26a‴, 26a"" and the rim 28a, the support rim 30a, 30a', 30a", 30a‴, 30a"" is arranged, which connects the switching cap 26a, 26a', 26a", 26a‴, 26a"" to the rim 28a. The rims 28a each ensure the connection of the respective switching element 18a, 18a', 18a", 18a‴, 18a"" to the handle unit 14a. The rims 28a each connect directly to an inner boundary wall of the recess 68a. The edge ribs 28a are preferably bonded to the inner boundary wall of the recess 68a and thus to the handle body 22a. The edge ribs 28a are, by way of example, inserted into the recess 68a by injection molding. A positive fit is formed between the handle unit 14a and the switching element 18a, 18a', 18a", 18a‴, 18a"" or its edge rib 28a.The inner boundary wall of the recess 68a and / or the outer edge ribs 28a each have at least one positive-locking projection, in particular at least one positive-locking rib, which engages in a corresponding recess, in particular a groove, to provide a positive lock between the handle base body 22a and the edge ribs 28a. Alternatively, a connection can also be achieved by adhesive bonding. Various implementations of the edge rib 28a are conceivable that would appear sensible to a person skilled in the art. The edge ribs 28a each extend over the entire height of the recess 68a. The edge ribs 28a are essentially ring-shaped. The edge webs 28a connect directly to the inside of the carrier edge 30a, 30a', 30a", 30a‴, 30a"" of the respective switching element 18a, 18a', 18a", 18a‴, 18a"".The support edge 30a, 30a', 30a", 30a‴, 30a"" is formed between the edge web 28a and the switching cap 26a, 26a', 26a", 26a‴, 26a"" of the same switching element 18a, 18a', 18a", 18a‴, 18a"". The support edges 30a, 30a', 30a", 30a‴, 30a"" connect directly to the respective edge web 28a on the outside, in particular on an outer circumference. Furthermore, the carrier edges 30a, 30a', 30a", 30a‴, 30a"" connect directly to the respective switching cap 26a, 26a', 26a", 26a‴, 26a"" on the inside, in particular on an inner circumference. The support edges 30a, 30a', 30a", 30a‴, 30a"" are each ring-shaped. The support edges 30a, 30a', 30a", 30a‴, 30a"" of the edge webs 28a are arranged in a round, in particular ring-shaped, configuration around the respective switching cap 26a, 26a', 26a", 26a‴, 26a"" The support edges 30a, 30a', 30a", 30a‴, 30a"" each have a width of 0.5 mm to 5 mm.Preferably, the minimum distance between the switching cap 26a, 26a', 26a", 26a‴, 26a"" and the edge web 28a of the same switching element 18a, 18a', 18a", 18a‴, 18a"" is 0.5 mm to 5 mm, preferably 0.7 mm to 3 mm. The support edges 30a, 30a', 30a", 30a‴, 30a"" each have a thickness of 0.5 mm to 3 mm, preferably 0.7 mm to 1.5 mm.

[0110] The five mechanical switching elements 18a, 18a', 18a", 18a‴, 18a"" are connected to each other in one piece. The five mechanical switching elements 18a, 18a', 18a", 18a‴, 18a"" are arranged side by side. The switching elements 18a, 18a', 18a", 18a‴, 18a"" are arranged in a row. The switching elements 18a, 18a', 18a", 18a‴, 18a"" are arranged one behind the other along the main direction of extension 54a of the oral hygiene product 10a. The switching elements 18a, 18a', 18a", 18a‴, 18a"" can have different shapes and / or sizes, such as length, width, and height. The switching elements 18a, 18a', 18a", 18a‴, 18a"" have different sizes. In a top view from the front, the switching elements 18a, 18a', 18a", 18a‴, 18a"" each have a circular basic shape. Furthermore, the switching elements 18a, 18a', 18a", 18a‴, 18a"" each have different diameters.The diameter of the switching elements 18a, 18a', 18a", 18a‴, 18a"" decreases, for example, from a lower end of the oral hygiene product 10a towards the neck area 64a. The first switching element 18a has the largest diameter. The diameter of the second switching element 18a' is smaller than the diameter of the first switching element 18a. The diameter of the third switching element 18a" is smaller than the diameter of the second switching element 18a'. The diameter of the fourth switching element 18a‴ is smaller than the diameter of the third switching element 18a”. The diameter of the fifth switching element 18a"" is smaller than the diameter of the fourth switching element 18a‴. The switching elements 18a, 18a', 18a", 18a‴, 18a"" are each directly connected to one another and are in abutting each other. Edge webs 28a of the switching elements 18a, 18a', 18a", 18a‴, 18a"" are each in abutting each other.Preferably, the distance between the switching elements 18a, 18a', 18a", 18a‴, 18a"" is each the sum of 0.5 * diameter of a first switching cap 26a of the first switching element 18a, the width of the support edge 30a of the first switching element 18a, the width of the edge web 28a, the width of the support edge 30a' of the second switching element 18a and 0.5 * diameter of the second switching cap 26a' of the second switching element 18a'.

[0111] The switching elements 18a, 18a', 18a", 18a‴, 18a"" are arranged in the recess 68a. The switching elements 18a, 18a', 18a", 18a‴, 18a"" fill the recess 68a. The switching elements 18a, 18a', 18a", 18a‴, 18a"" completely close the recess 68a in a direction perpendicular to the main extension plane of the oral hygiene product 10a. The height of the recess 68a is determined in particular by the fact that the switching elements 18a, 18a', 18a", 18a‴, 18a"" must be held against the handle base 22a and therefore sufficient mounting surface must be available. The height of the edge of the recess 68a is from 3 mm to 15 mm, preferably from 5 mm to 10 mm. The switching elements 18a, 18a', 18a", 18a‴, 18a"" have a common circumferential rim 28a. The rims 28a of the switching elements 18a, 18a', 18a", 18a‴, 18a"" are connected to form a rim 28a.The common rim 28a is geometrically extended between the switching elements 18a, 18a', 18a", 18a‴, 18a"". Furthermore, the rim 28a between two switching elements 18a, 18a', 18a", 18a‴, 18a"" is designed as a raised section 72a in the same material as the switching elements 18a, 18a', 18a", 18a‴, 18a"". The rim 28a therefore does not lie against the handle body 22a everywhere. Each of the switching elements 18a, 18a', 18a", 18a‴, 18a"" thus has a separate switching cap 26a, 26a', 26a", 26a‴, 26a"" and a separate support rim. 30a, 30a', 30a", 30a‴, 30a"" are formed, with the edge webs 28a of the switching elements 18a, 18a', 18a", 18a‴, 18a"" merging into one another. The handle base body 22a forms a frame with the longitudinal webs 70a, 70a', which directly encloses the common edge web 28a.

[0112] Furthermore, the handle body 22a has a thumb grip area 32a. The handle body 22a also has a palm grip area 74a. One of the switching elements 18a, 18a', 18a", 18a‴, 18a"" is integrated into the thumb grip area 32a. By way of example, the fourth switching element 18a‴ and / or the fifth switching element 18a"" is integrated into the thumb grip area 32a. Furthermore, the first, second, and third switching elements 18a, 18a', 18a" are integrated into the palm grip area 74a.

[0113] The Figure 12Figure 76a shows a system 76a with the oral hygiene product 10a and a protective cap 38a in a schematic representation. The protective cap 38a is a protective cap for the oral hygiene product. In particular, the protective cap 38a is designed as a toothbrush cap, preferably intended for placement on a single toothbrush. However, particularly in the case of a differently designed oral hygiene product 10a, the protective cap 38a can also be designed differently. For example, it can be designed as a protective cap 38a for a flosser, a tongue cleaner, a single-tuft brush, an interdental cleaner, or the like. The protective cap 38a has a cap body 40a that defines at least one interior space 42a, which is intended to receive at least a portion of the oral hygiene product 10a.In the present case, the interior space 42a is provided for receiving at least part of the application unit 12a and, in particular, for receiving the brush head 34a. The cap body 40a has at least one suspension 78a.

[0114] The following will refer to the Figures 12 to 14 Reference is made to the different representations of system 76a and protective cap 38a. Due to the different views, some elements are not shown in all figures and therefore not labeled with reference symbols in all figures. Furthermore, for the sake of clarity, not all elements shown in the Figures 1 to 11 The introduced reference symbols for units and elements of the oral hygiene product 10a are shown. Reference is made to these figures when appropriate.

[0115] In this case, the hanger 78a is hook-shaped. The hanger 78a is designed as a U-shaped hook. When the protective cap 38a is in place, the hanger 78a is positioned above the brush head 34a of the oral hygiene product 10a. Specifically, the oral hygiene product 10a can be suspended from the hanger 78a when the protective cap 38a is in place, for example, from a hook, a rod, an eyelet, a handle, a cord, or the like. Other types of hangers are also conceivable, such as magnetic hangers, suction cup hangers, hook-and-loop hangers, eyelet hangers, or the like. Furthermore, it is also possible to design the protective cap 38a without a hanger. In this case, the hanger 78a is designed as a hollow body. An interior space of the hanger 78a is connected to the interior space 42a of the cap body 40a.The hanger 78a is directly molded onto the interior 42a.

[0116] In the present case, the cap body 40a is formed in one piece. Furthermore, in the present case, the cap body 40a is formed entirely from a hard component.

[0117] The cap body 40a has at least two shell elements 80a, 80a' connected to each other by hinges, in particular at least one first shell element 80a and at least one second shell element 80a'. In the present case, the shell elements 80a, 80a' essentially form mirror-symmetrical halves of the cap body 40a. The locking mechanism of the two shell elements 80a, 80a'' for closing the protective cap 38a on the front side is not mirror-symmetrical. The cap body 40a has a film hinge 84a on the rear side, which connects the shell elements 80a, 80a' to each other by hinges. In the present case, the cap body 40a has a single film hinge 84a. The film hinge 84a is arranged on the rear side of the protective cap 38a.

[0118] The cap body 40a has a passage 82a through which, in the fitted state, the neck region 64a of the oral hygiene product 10a enters the interior 42a of the cap body 40a. Preferably, a cross-section of the passage 82a is adapted to a cross-section of the neck region 64a, whereby a certain amount of clearance may be provided.

[0119] Furthermore, the protective cap 38a has at least one one-piece mechanical switching element 44a, 44a' fixedly arranged on the cap body 40a, which is made of an elastic material and has at least two defined static states that are distinct from one another. The protective cap 38a has two one-piece mechanical switching elements 44a, 44a' fixedly arranged on the cap body 40a, each made of an elastic material and each having two defined static states that are distinct from one another.

The switching caps 26e are each arranged directly in one of the recesses 68e and fill it completely. The switching caps 26e are directly connected to the tongue cleaner head 98e.

[0156] The switching elements 18e each have a significant functional surface 20e, which is convexly curved in the first equilibrium state and concavely curved in the second equilibrium state. The functional surfaces 20e of the switching elements 18e are dome-shaped, in particular hemispherical, in the first equilibrium state and bowl-shaped in the second equilibrium state. The functional surfaces 20e of the switching elements 18e are each formed by the upper surface of the switching cap 26e of the respective switching element 18e. The functional surfaces 20e are arranged on the front surface 46e of the oral hygiene product 10e.

[0157] Cleaning elements 36e are arranged on each of the functional surfaces 20e. Each switching element 18e incorporates the cleaning elements 36e. The cleaning elements 36e are formed integrally with a switching cap 26e of the respective switching element 18e. The cleaning elements 36e are injection-molded and manufactured as a single casting with the respective switching element 18e. The cleaning elements 36e are, by way of example, formed integrally with the respective switching element 18e. The cleaning elements 36e are arranged projecting from the respective functional surface 20e. The cleaning elements 36e on the switching element 18e can be designed as bristles and / or as lamellae. The cleaning elements 36e are shown, by way of example, as injection-molded bristles. However, other designs for the cleaning elements 36e that would appear sensible to a person skilled in the art would also be conceivable.The cleaning elements 36e can form different cleaning patterns depending on the state of the respective switching element 18e. The switching elements 18e have the function that the cleaning area 62e of the application unit 12e is partially customizable. Thus, each of the switching elements 18e can, for example, form a differently shaped cleaning field in the first equilibrium state than in the second equilibrium state. In the first equilibrium state, the cleaning elements 36e are fanned out on the switching caps 26e, for example, in a stalk-like arrangement. In the second equilibrium state, the cleaning elements 36e are arranged conically on the switching caps 26e, with the free ends of the cleaning elements 36e converging.In the first equilibrium state, the cleaning elements 36e of the switching elements 18e are primarily used for tongue cleaning, while in the second equilibrium state, the cleaning elements 102e of the cleaning surface 100e are primarily used for tongue cleaning. Furthermore, the switching elements 18e can function as a contact pressure control, whereby in the first equilibrium state, the switching elements 18e, together with the cleaning elements 36e, are pushed away if the pressure is too high and transition to the second equilibrium state.

[0158] The Figure 25Figure 46f shows a partial section of a front face of an oral hygiene product 10f in a schematic perspective view. In this case, the oral hygiene product 10f is designed as a toothbrush. The oral hygiene product 10f has at least one application unit 12f. Furthermore, the oral hygiene product 10f has at least one handle unit 14f. The oral hygiene product 10f has a longitudinal axis, a vertical axis, and a horizontal axis.

[0159] The at least one application unit 12f has a head region 58f. The head region 58f forms a brush head 34f of the application unit 12f. In the present case, the head region 58f, in particular the brush head 34f, is designed as a toothbrush head. The brush head 34f has, in particular, a base body 60f designed as a bristle carrier. The base body 60f of the brush head 34f is formed entirely from a hard component. However, it would also be conceivable that the base body 60f of the brush head 34f is formed from a hard component and a soft component. The base body 60f of the brush head 34f forms a bristle carrier. The oral hygiene product 10f further has a cleaning area 62f received by the brush head 34f, which comprises a plurality of bristle bundles. At least one recess is formed on the front of the brush head 34f.At least one recess is provided for receiving a bristle bundle of the cleaning area 62f. The brush head 34f has a plurality of recesses. The recesses are formed by bristle holes, each designed to receive a bristle bundle. Any suitable bristles can be used for the bristle bundles; these can be, for example, stamped using the anchor punching method, as described above.

[0160] The application unit 12f is arranged on the upper side of the oral hygiene product 10f. Furthermore, in this case, the application unit 12f comprises at least one neck section 64f, which in particular connects the head section 58f with the handle unit 14f. The neck section 64f forms a neck. The neck section 64f forms a transition between the application unit 12f and the handle unit 14f.

[0161] Furthermore, the oral hygiene product 10f has a functional unit 16f, which is arranged on the application unit 12f. The functional unit 16f is arranged on the brush head 34f. The functional unit 16f is integrated into the brush head 34f. The functional unit 16f is arranged on an outer surface of the brush head 34f. The functional unit 16f consists entirely of a soft component.

[0162] The functional unit 16f comprises at least one one-piece mechanical switching element 18f, which consists of an elastic material and which has at least two defined static states that are distinct from one another. The functional unit 16f comprises exactly one one-piece mechanical switching element 18f. The switching element 18f has exactly two defined static states that are distinct from one another, namely a first equilibrium state, in particular an initial state, and a second equilibrium state, in particular a deflection state. In the Figure 25 The switching element 18f is in the first equilibrium state. In the Figure 26The switching element 18f is in the second equilibrium state. The first equilibrium state is an unloaded state. Furthermore, the switching element 18f is at least partially pre-tensioned in the second equilibrium state, particularly the deflection state. The switching element 18f can be moved manually by an operator, in particular by applying a push or pull force to the switching element 18f, from one equilibrium state to the other. For this purpose, the switching element 18f is flipped.

[0163] The switching element 18f is formed by a switchable, in particular foldable, collar. The switching element 18f can form a combination of a switching cleaning and / or massage element and a switching tongue cleaner. When folded up, the switching element 18f can serve as an additional cleaning or massage element around the cleaning area 62f, which at least partially surrounds a bristle field of the brush head 34f. When folded down, the switching element 18f can serve as a tongue cleaner, while the bristle field is free of an additional cleaning element. The switching element 18f has a U-shaped wall 104f, which extends in a U-shape around an upper edge of the brush head 34f. The wall 104f, in particular, delimits three sides of the brush head 34f.In the first equilibrium state, an upper free edge of the wall 104f of the switching element 18f points towards the front 46f of the oral hygiene product 10f, and in a second equilibrium state towards a rear 56f of the oral hygiene product 10f. The wall 104f of the switching element 18f has, in particular, a maximum height transverse to a longitudinal axis 48f at a topmost point of the oral hygiene product 10f. The wall 104f of the switching element 18f tapers towards the neck region 64f. Further structures may be attached to the edge or surface of the switching element 18f, especially to the upper free edge of the wall 104f. These structures serve, in particular, to...

[0164] Support for cleaning, such as in one case for tongue cleaning and / or in another for tooth cleaning. A free edge of the switching element 18f can have various designs that appear useful to a specialist, such as not straight, but continuously or continuously wavy, with bumps on the edge and / or with small bristles on the edge. The side surfaces of the switching element 18f could be provided with recesses, such as blind holes or through holes and / or with bumps. Alternatively or additionally, the switching element 18f can have a structure, such as an EDM structure.

[0165] Alternatively, a combination of a switchable head holder and a switchable tongue cleaner would also be conceivable. When folded up, the switchable element 18f can serve as a head holder, which at least partially surrounds a bristle field of the brush head 34f, and when folded down, it can serve as a tongue cleaner.
