[0001] The invention relates to an oral hygiene product.

[0002] An oral hygiene product such as an interdental brush, a flosser or a toothbrush or other oral hygiene product with at least one application unit and with at least one handle unit connected to the application unit, which has at least one material handle body, has already been proposed.

[0003] Oral hygiene products are already known from DE 20 2020 000 613 and WO 2014 / 169398 A1.

[0004] Furthermore, oral hygiene products with an application unit and a handle unit connected to the application unit, which has at least one material handle body, are already known from US 6 336 242 B1, US 3 609 789 A, CN 207 011 911 U, CN 1 129 403 C and JP 2018 143644 A.

[0005] The object of the invention is, in particular, to provide a generic device with improved properties with regard to manufacturability, comfort, and environmental impact. This object is achieved according to the invention by the features of claim 1, while advantageous embodiments and further developments of the invention can be found in the dependent claims. Advantages of the invention

[0006] The invention relates to an oral hygiene product, such as an interdental brush, a flosser or a toothbrush, or other oral hygiene product with at least one application unit and with at least one handle unit connected to the application unit, which has at least one material handle body, wherein the material handle body of the handle unit or the material handle body of the handle unit and the application unit consists at least partially, in particular at least to a large extent, of a paper material.

[0007] Preferably, the paper material consists in particular of fibers, and various processing options are available. The paper material can also be treated. It can be coated, for example, varnished (e.g., with a varnish to improve bonding), and / or impregnated. The paper material can be in flat form, in block form, or in liquid to cardboard-like form and / or consistency, with various processing options depending on the form. In flat form, the paper material can be rolled, layered, pressed, laminated, scored, embossed, folded, die-cut, and / or grained, i.e., roughened or granulated.Paper materials can be joined by gluing, which may require preparatory steps such as graining or similar processes; by welding, particularly using ultrasonic welding; by sealing (hot or cold); or by laminating, etc. Special layers may be required on the paper material to create the bond. Connections can be made with paper materials or other materials mentioned in this document. In block form, paper materials can be mechanically processed, for example, by milling. In liquid form, paper materials can be cast or injection molded, particularly using paper injection molding or paper casting. In this process, the paper material is shaped in a cavity, similar to a direct injection molding process. The cast part is then hardened or dried. Paper injection molding also allows for injection molding onto other parts.Materials such as plastic overmolded with paper are conceivable. Alternatively, a plastic part can also be injection-molded onto a paper base. Overall, the product structure of the personal care product can vary, including being made entirely from a paper base or using a hybrid technique, for example, combining paper and plastic, particularly with features such as an interchangeable head and / or a paper handle and a plastic applicator. Other material combinations with paper, as mentioned, can include plastic and / or metal and / or organic materials such as wood, bamboo, and / or inorganic materials such as stone, glass, etc.

[0008] The inventive design of the personal care product provides advantageous properties with regard to ergonomics and manufacturability. In particular, it allows for the provision of an advantageously environmentally friendly personal care product. Furthermore, it facilitates advantageously simple disposal of the personal care product.

[0009] The personal care product is an oral hygiene product. An "oral hygiene product" is understood to include, in particular, a toothbrush and / or an interdental cleaner, especially an interdental brush, and / or a flosser and / or a tongue cleaner and / or a toothpick. The oral hygiene product is advantageously designed as a toothbrush, especially a manual toothbrush, as an interdental brush, and / or as a flosser. Alternatively, the oral hygiene product can be an electric toothbrush. If designed as a toothbrush, the oral hygiene product can be, in particular, a disposable toothbrush, a reusable toothbrush, or a toothbrush with replaceable heads. However, the oral hygiene product could also be a brush product in general. A "personal care product" is understood to include, in particular, an oral hygiene brush and / or a cosmetic brush and / or a hairbrush and / or a household brush.Oral hygiene brushes include, for example, 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, in injection-molded form, or as flossers; tongue cleaners; and / or dental floss. Personal care products, particularly cosmetic brushes, include, for example, 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. Household brushes include, for example, dish brushes, floor mops, and / or brooms.

[0010] In the case of a toothbrush, it is particularly 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. Preferably, the personal care product consists of an application unit with bristles and the handle unit, wherein the application unit particularly has a neck section that connects the application unit to the handle unit. All components can consist of at least one hard and / or one or more soft components.

[0011] The personal care product has, in particular, a longitudinal axis which is advantageously arranged at least substantially parallel to a principal direction of extension of the personal care product. Preferably, the longitudinal axis runs at least partially within the personal care product and, in particular, through its center of gravity. Specifically, the longitudinal axis of the personal care product is a central axis of the personal care 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.

[0012] Advantageously, the application unit has at least one cleaning area intended for dental cleaning, particularly in the user's oral cavity. Preferably, the cleaning area comprises at least one cleaning unit. The cleaning unit can include a brush head, advantageously a toothbrush head, preferably with multiple bristles and / or bristle bundles and / or injected cleaning elements or injected bristles and / or soft, elastic cleaning elements. Alternatively or additionally, the cleaning unit can also be designed as an interdental brush and / or as a single tuft (e.g., a single large bristle bundle) and / or as an arch covered with dental floss and / or an interdental tape, preferably an interdental tape, particularly as a flosser, or the like.Furthermore, the application unit advantageously comprises at least the neck and / or bracket element, which is preferably connected to the cleaning area, particularly directly and / or in one piece. "In one piece" is understood to mean, in particular, at least a material-bonded connection, for example, by a joining process such as welding, bonding, injection molding, 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 manufacturing from a single casting and / or by manufacturing using a single- or multi-component injection molding process, and advantageously from a single blank. "Provided for" is understood to mean, in particular, specially designed and / or equipped.The fact that an object is intended for a specific function should be understood in particular to mean that the object fulfills and / or performs this specific function in at least one application and / or operating state.

[0013] Preferably, the handle unit has at least one handle element, which is advantageously designed for one-handed gripping. It is conceivable that the handle element is at least partially tapered and / or has a concave surface area and / or a convex surface area. This advantageously allows for a secure grip and optimizes ergonomics. The handle element is particularly preferably elongated, with one longitudinal axis of the handle element advantageously corresponding to the longitudinal axis of the personal care product. The handle element is at least partially, and in particular entirely, made of at least one paper material. Alternatively or additionally, the handle element and / or the handle unit can be made at least partially of a hard component and / or of one or more soft components.Preferably, the handle material is made at least largely, and in particular entirely, from at least one paper material. In particular, the handle element advantageously comprises 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 personal care product and, in particular, on the front of the handle element. It is conceivable that the thumb grip area and / or the hand grip area comprise at least one element and / or a surface texture made of at least one paper material, at least one soft component, and / or at least one hard component.

[0014] The plastics used for manufacturing, consisting of hard and / or soft components and processed by injection molding, can be classified in particular as follows: Conventional materials: Materials, essentially virgin materials, that are largely petroleum-based. Sustainable materials: as listed below and described later, preferably bio-based, biodegradable, and / or recycled. Bio-based materials: Material that is made from renewable raw materials, preferably more than 60%, preferably more than 80%, and most preferably 100%. A further possible additional property of bio-based materials is, in particular, that they are biodegradable. Preferably, the materials are not based on foodstuffs such as corn, etc. Biodegradable materials: Material that is biodegradable according to current standards. This includes, in particular, compostability (industrially or non-industrially). Materials made from renewable raw materials can possess this property.• Recycled materials: Materials that come from a recycling process, such as post-consumer recycled materials, ocean waste plastic, or social plastic.

[0015] The materials used can be recyclable. For recyclable materials, a recycling option is advantageous after use.

[0016] 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). In addition, polyesters such as polyethylene terephthalate (PET), especially in the form of acid-modified polyethylene terephthalate (PETA) or glycol-modified polyethylene terephthalate (PETG), polybutylene terephthalate (PBT), acid-modified polycyclohexylenedimethyl terephthalate (PCT-A), glycol-modified polycyclohexylenedimethyl terephthalate (PCT-G) or the like are 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.

[0017] It is advantageous to use hard components for stable and / or load-bearing elements, particularly in the handle element and / or in a support element of the application unit and / or a fastening unit or the like. It is also advantageous to consider that a hard component and a soft component used may have different colors, so that surface textures, lettering, motifs, and the like can be achieved through appropriate design of the base body and the soft element.

[0018] 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 soft component can be sustainable materials.

[0019] In the case of a toothbrush, the personal care product has, in particular, a front and a back, which are preferably arranged facing away from each other. Preferably, the cleaning area of ​​the application unit is located on the front of the personal care product. The front is, in particular, a side of the personal care product visible in a viewing direction perpendicular to both the longitudinal and transverse axes of the product. The front of the personal care product is specifically the side of the brush on which the thumb rests. The front is also normally the side towards which the bristles are directed. Advantageously, the back corresponds to a side of the personal care product visible in the opposite viewing direction. The back of the personal care product is the side of the toothbrush opposite the bristles.The left side of a personal care product refers specifically to the side that is on the left when viewed perpendicularly from the front of the product. The right side refers specifically to the side that is on the right when viewed perpendicularly from the front of the product. The top refers specifically to the end of the personal care product where the cleaning area is located. The bottom refers specifically to the end of the personal care product opposite the top, which is closest to the grip area.

[0020] Furthermore, it is proposed that, in the case of a personal care product designed as a toothbrush, 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 conventionally 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 are conceivable, including the sustainable materials listed in this document.Furthermore, it is conceivable that at least some of the bristles have a tapered end and / or a variable cross-section at the end used. Preferably, the bristles are made of a single material, or even a mixture. However, multi-component bristles 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 attached to the toothbrush handle using adapted methods, such as the anchor punching method or an anchorless method.

[0021] In particular, cylindrical or pointed bristles with a round cross-section are suitable, although any other cross-sections such as polygonal, triangular, rectangular, square, elliptical, star-shaped, trapezoidal, cruciform, parallelogram-shaped, rhombus-shaped, or any other cross-sections are conceivable. 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 alternately.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 that are not part of the invention, 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 (e.g.,Suitable materials include PBT and PET, although sustainable materials are also possible, and the bristles can be tapered mechanically and / or chemically. Other materials are also conceivable. Preferably, the bristles are straight in the longitudinal direction; however, wavy, twisted, helical, and / or coiled bristles are also conceivable, as are combinations of different bristles. Bristles with a smooth surface are also conceivable, as are bristles with a textured surface.

[0022] Furthermore, the bristles, particularly as bristle bundles, are preferably processed by at least one anchor punching method or an anchorless method 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 preferably drilled and / or injection-molded. In the case of anchor punching, it is conceivable, for example, 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 attached in a blind hole by means of at least one anchor, in particular by punching.A loop punch is also conceivable.

[0023] Alternatively, as mentioned, anchorless methods are also conceivable, whereby the 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 punch. For example, it is conceivable that the bristle bundles are first individually fused and / or their bristle ends are subsequently, for example, overmolded or fixed by material compaction of the brush head. Bristle bundles can advantageously be joined together in this process.

[0024] 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. Bristle plates fitted in this way can then be connected to a base body, in particular a brush head, e.g., welded and / or bonded, 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 the side that is placed in a recess in the base body and faces the back of the personal care product. Conversely, the top side of the bristle plate faces the front of the personal care product.

[0025] 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.

[0026] 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. Bristle bundles can then be advantageously inserted into the blind holes and anchored by pressing the brush head into place. In particular, the heated blind holes deform in this process, thus anchoring the bristle bundles within them.

[0027] As an alternative or in addition to stamped, welded, and / or glued bristles, injection-molded bristles are also conceivable. These can be manufactured together with the application unit, handle unit, and / or coupling unit during multi-component injection molding, or subsequently injection-molded onto a base body of the application unit. Unlike conventional bristles, injection-molded bristles are not extruded.

[0028] Another possible method for attaching bristles to the brush head is twisting, which creates a cylindrical brush. In this process, bristles or filaments are fed from a spool, with several bristle / filament strands wound onto a single spool. For machine feeding, several spools are pre-tensioned, as each bristle / filament in the brush corresponds to a bristle / filament strand. The bristles / filaments are spread out to the correct width for insertion into the brush. The bristles / 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 unwound from a spool and fed into the machine.The wire is cut to a length greater than the unwound length of the twisted brush. The final trimming of the bristles / filaments takes place after twisting. The wire is bent into a U-shape so that the open end can be slipped over the bristles / filaments to thread them through. The wire is held at the base of the U. The open end of the wire is then clamped to hold the bristles / filaments between the wire segments. The bristles / filaments are cut to a length greater than the final length in the brush so that the brush can be trimmed correctly once the bristles / filaments are twisted in. The wire is twisted to clamp and secure the bristles / filaments within the wire. After the bristles / filaments are fixed in the wire, they are trimmed and shaped to the correct length.Once the brush part is finished, the excess wire is cut off.

[0029] Preferably, during an injection molding process, particularly a two- and / or multi-component injection molding process, the materials of the injection-molded bristles do not form a material bond with other soft and / or hard components and / or other materials of the personal care product. Instead, the injection-molded 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, particularly with affine or compatible plastic materials or components, is also conceivable.

[0030] 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.

[0031] Alternatively or additionally to a brush head with bristles, the application unit can also include at least one tongue cleaner and / or at least one alternative cleaning and / or massage element. These can each be made of a soft component, a hard component, or a combination of soft and hard components, and / or can be advantageously manufactured by injection molding.

[0032] 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 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.

[0033] In principle, the use of water-soluble polymers is also conceivable, for example for hard components, soft components, injected bristles, tongue cleaners or other elements of the personal care product.

[0034] Similarly, bioplastics can be used for the hard component, the soft component, and / or the material for injection-molded bristles. These bioplastics may be derived from renewable raw materials, be biodegradable, particularly compostable, and / or consist of recycled and / or recyclable material. Preferably, the material is made of a plastic. Preferably, the biodegradable, particularly compostable, and / or recycled and / or recyclable material is made of a bioplastic, particularly a plastic based on renewable raw materials and / or a biodegradable plastic.The material can therefore be fossil-based and biodegradable, such as PVOH, PCL, PBAT, PET, or PBS; based on renewable raw materials and biodegradable, such as PLA, PHA, cellophane, or starch blends; or based on renewable raw materials but not biodegradable, such as Ca, bio-PE, bio-PP, bio-PA, or bio-PET. Various bioplastics that would appear suitable to a person skilled in the art are conceivable, such as starch-based bioplastics, cellulose-based bioplastics, polyhydroxyalkanoates, such as polyhydroxybutyric acid (PHB), polylactic acid (PLA), aliphatic and / or aromatic copolyesters, or other bioplastics such as lignin-based bioplastics. Preferably, the application unit or handle unit can consist largely of a biodegradable, in particular compostable, and / or recycled material.Preferably, the personal care product consists of only one component. In particular, the personal care product has a hard component. The material of the handle of the application unit or handle unit can consist at least partially of the hard component. The hard component and / or the soft component and / or the material for injected bristles advantageously consists of a bioplastic, which can be derived from renewable raw materials. Suitable raw materials include, in particular, corn, hemp, sugar, castor oil, palm oil, potatoes, wheat, sugar cane, rubber, wood, the castor bean plant / castor oil plant, and the like. Corresponding possible base materials could be, for example, cellulose, starch, PLA, glucose, chitin, chitosan, or the like, from which suitable bioplastics can be synthesized.

[0035] Furthermore, the use of sustainable dental floss is also conceivable, particularly floss made from the aforementioned sustainable materials such as renewable materials like cellulose, organic materials like natural silk, etc. The use of these sustainable materials for bristles / filaments, such as cellulose bristles / filaments, is also conceivable. Additionally, the use of these sustainable materials for plastic films, especially instead of or in combination with a paper material, such as PLA films, for flossers or other applications is also conceivable. Films are primarily used as laminates with the paper material.

[0036] Furthermore, it is conceivable that the personal care product is provided with separation aids and / or predetermined breaking points at which it can be disassembled, separated, or divided for disposal, so that the various components or materials can be at least partially separated by type for disposal. For example, pull tabs can be provided, perhaps between layers to be separated, allowing the layers to be pulled apart. Alternatively or additionally, unconnected, unsealed, or unwelded sections can be provided for separation. Furthermore, supporting perforations can be provided, for example, to separate the brush and paper, particularly in the case of interdental brushes or flossers. Preferably, separation aids such as pull tabs, pull tabs, and / or perforations are provided on the personal care product.

[0037] The term "at least to a large extent" is understood to mean, in particular, that at least one major component of the material of the handle body of the handle unit and / or the application unit is a paper material. Preferably, at least 50 wt.%, preferably at least 70 wt.%, and particularly preferably at least 90 wt.% of the material of the handle body of the handle unit and / or the application unit is made of a paper material. Particularly preferably, the material of the handle body of the handle unit and / or the application unit consists entirely of a paper material. Furthermore, in this context, "paper material" is understood to mean, in particular, a material, preferably sheet-like, that consists essentially of fibers, preferably of plant origin. The material is preferably produced by dewatering a fiber suspension on a screen. The resulting fiber web is then, in particular, compacted and dried.Preferably, the material is made from pulp, groundwood, and / or recycled paper. The material can be single-ply or multi-ply. Multi-ply paper consists of several layers of paper of different thicknesses and / or properties and / or at least partially of different materials. The layers can be produced by gluing or pressing them together, particularly without the use of adhesives. The basis weight of the paper material is preferably between 50 g / m² and 1000 g / m², and preferably between 150 g / m² and 600 g / m². According to DIN 6730, different paper materials can be distinguished based on their basis weight. For example, paper with a basis weight up to 225 g / m² is considered paper, while paper with a basis weight above 225 g / m² is considered cardboard. In everyday language, materials up to 250g / m² are referred to as paper, those from 150g / m² to 600g / m² are referred to as cardboard, and those from 500g / m² are referred to as paperboard.For cardboard, solid board or corrugated board are suitable options. There are various types of cardboard, including recycled versions. Preferably, the paper material, especially in the case of cardboard and particularly solid board, consists of virgin fiber and / or recycled fiber. The virgin fiber, or primary fiber, is derived from new material, such as FSC-certified wood. The recycled fiber is derived from recycled paper or cardboard. Alternatively or additionally, other fillers, such as grass for grass paper, are also conceivable. Paper is made from fibrous materials, which today are primarily derived from wood. Wood-free cellulose is also a possibility. However, the preferred base for paper is cellulose or wood pulp. Possible wood species include poplar, beech, spruce, pine, or eucalyptus.Alternatively, paper can also be made from grass, bamboo, or papyrus. The most important fiber materials are pulp, wood pulp, and recycled paper. Some recycled paper may be less suitable for oral hygiene due to the presence of printing ink. In addition to the fiber or a fiber mixture, the material often contains fillers and other additives. Preferably, the paper has a recycled content of at least 80%, although it may also contain a proportion of virgin fibers. By using virgin material, the properties of the paper can be kept within a narrower range, and, among other things, improved tear resistance and thus stability can be achieved. Various paper materials that would appear suitable to an expert are conceivable.Furthermore, it is conceivable that the paper material is coated, i.e., coated or uncoated, or textured, for example, with a 3D contour. Texturing and / or coating can particularly improve the grip of the personal care product. Specifically, the texturing can be achieved both within the paper material itself, for example, through surface treatment and / or embossing, and through printing. Preferably, the paper material is manufactured without an injection molding or extrusion process, with the exception of fiber casting or fiber injection molding, which, compared to the processing of thermoplastics, is carried out at lower temperatures or lower pressures. The temperature is in the range of a maximum of 200°C, and the pressure is between 10 bar and 40 bar, preferably between 20 bar and 35 bar.In particular, the production of the paper material does not involve a melting process of thermoplastics.

[0038] The paper material can be supplied in various ways that a specialist might consider appropriate, such as sheets, rolls, blocks, granules, or raw material. The block, for example, can be made of cardboard and intended for mechanical processing such as milling.

[0039] Depending on the application, the paper material can have different densities or thicknesses. Possible basis weights include, for example, a cardboard sheet with a basis weight of 330 g / m², particularly two such sheets bonded together, e.g., welded, laminated, etc., for a flosser or an interdental brush. Possible densities or thicknesses per layer can range from 150 g / m² to 650 g / m², preferably from 250 g / m² to 500 g / m², and particularly preferably from 300 g / m² to 400 g / m² when several sheets or layers are bonded together. In oral hygiene products where sheet-like layers of paper materials are used (e.g., for flossers or an interdental brush), at least two layers of paper material are preferably used. However, two, three, four, or five layers can also be used. The layers can have different basis weights and paper materials. The layers can also include plastic films.Preferably, the plastic films are covered on both sides with layers of paper materials. The layers can be produced by folding a sheet of paper material. Two or more folds can be made. The folds can be sequential or rolling, or they can alternate sides (accordion fold).

[0040] In oral hygiene products that use rolled layers of paper materials (such as toothbrushes, interdental brushes, wet razors, etc.), the rolling process achieves stability primarily through the number of layers or turns. This allows, for example, the use of very thin paper starting at 40 g / m². Preferably, densities or thicknesses of 5 g / m² to 150 g / m², preferably 250 g / m², 10 to 80 g / m², and particularly preferably 20 g / m² to 50 g / m² are used in the rolling process. The number of layers or turns is adjusted according to the desired roll diameter, the internal cavity diameter (if desired), and the density or thickness of the paper material used. This results in a number of layers or turns ranging from 1 to 150, preferably 1 to 100, and particularly preferably 1 to 80. Two, three, four, or five layers of material can also be used in the rolling process.The layers can have different basis weights and paper materials. The layers can include plastic films. Preferably, the plastic films are covered on both sides by layers of paper materials. The rolling process can be a continuous winding with a strip of paper material.

[0041] Preferably, the paper material can be made from wood-free coated cardboard. Depending on the application, the surface of the paper material can be coated, printed, embossed, or otherwise treated. High tear resistance and, at least from the application perspective, a high water barrier are particularly advantageous for the paper material. The tear resistance is between 20 N and 100 N, preferably between 30 N and 60 N.

[0042] The plastic content of the total weight of the personal care product is less than 10%, preferably less than 5%, most preferably less than 3%. The plastic content consists in particular of film or dental floss thread / band.

[0043] Furthermore, the paper material can be additionally treated, particularly to achieve additional properties. For example, a coating may be applied to the surface of the paper material in the form of a varnish, adhesive, a physical and / or chemical treatment for water resistance, or a finishing treatment.

[0044] Furthermore, fillers for the paper stock are conceivable. In particular, insoluble and soluble fillers are possible. Potential fillers include, for example, silver particles for antibacterial additives; polymers for improved water resistance, such as in the production of paper cups; abrasives (to increase the coefficient of friction), for example, to improve cleaning performance if the paper stock is used in the cleaning unit or to improve grip if the paper stock is used in the handle unit; and / or magnetic particles for magnetic paper, for example, for holding or storing personal care products.

[0045] Other fillers that dissolve during use may include the following active substances, which are bound in a suitable carrier and released: a) Active ingredients with toothpaste-like effects: Sorbitol, flavorings, hydrated silica, sodium lauryl sulfate, sodium monofluorophosphate, creatine, zinc sulfate, triclosan, glycerin, sodium saccharin, propylene glycol, disodium phosphate, alumina, trisodium phosphate, sodium fluoride, betaine, titanium dioxide, cellulose gum, tetrasodium pyrophosphate, etc. b) Active ingredients with antibacterial effects: sodium bicarbonate, citric acid, phosphoric acid, sodium carbonate, potassium carbonate, sodium perborate, sodium hexametaphosphate, sodium benzoate, sodium stearate, etc. c) Active ingredients to indicate brushing success by staining plaque on the tooth surface: glucose, maltodextrin, magnesium stearate, flavoring, saccharin, microcrystalline cellulose, etc. d) Flavoring ingredients e) Odor-emitting substances

[0046] Suitable paper materials are already known, for example, from Storaenso's cardboard for drinking cups, which is food-safe, waterproof, compostable, and printable. Furthermore, Kotkamills produces cardboard that is made waterproof using a dispersion and remains fully recyclable and compostable. Cardboard tubes are also already known.

[0047] The paper material can be pre-treated, for example, finished. "Finishing" refers to a surface treatment of the paper material that, for instance, gives it a higher-quality appearance. Finishing can be applied as, during, or after the printing process. It can also be applied during or after the assembly of the paper material with other elements of the personal care product. Finishing can be applied partially to one or more areas or across the entire surface. Finishing can create, for example, metallic effects, visual distinctions, or product markings. The appropriate coating can also reduce the paper material's water absorption, making it suitable for multiple uses.Finishing can take the form of a coating, such as UV high-gloss lacquer, textured lacquer, soft-touch lacquer, or glitter lacquer. It can also take the form of flocking. Embossing, such as silver foil stamping or hologram embossing, can be another finishing technique. Finally, scented lacquer can be applied.

[0048] Another pretreatment option is embossing the paper material. In this process, the paper material is at least partially deformed using pressure. This creates a three-dimensional design and / or surface texture in certain areas of the paper material's surface. Embossing can also be used to create cavities within the layers of the paper material. This improves the grip and slip resistance of the handle, thus facilitating the handling of the oral hygiene product. In principle, all paper materials can be embossed, regardless of whether they are in a flat, rolled, laminated, sealed, and / or welded state. Embossing can be achieved using an embossing tool (negative mold) and applying pressure and / or heat and / or steam, etc. Embossing can also be performed on flat surfaces during die-cutting of the paper material.However, it is also possible to perform embossing on a rolled paper material.

[0049] Preferably, the material handle body is layered from sheets, rolls, or panels. Furthermore, it is conceivable that the at least two layers are pretreated, printed, or finished before processing (see the additional details in this document). The pretreatment, printing, or finishing can affect only one layer. For example, embossing is conceivable as a pretreatment to create a structure on the surface of the final product. Alternatively or additionally, coating is conceivable as a pretreatment. For example, an inner surface of each layer could be designed for adhesive bonding, while an outer surface could provide protection against moisture. Each layer can therefore have two sides with different coatings. Alternatively or additionally, printing is conceivable as a pretreatment. Furthermore, it is conceivable that the at least two layers are post-treated after manufacturing.Post-treatment options include coating, printing, coating the application unit, and / or laminating. Preferably, the application unit is directly connected to the material handle body. In particular, the application unit is inserted between the layers of the material base body and bonded together with the paper material layers.

[0050] Foil lamination, foil lamination, and / or hot foil stamping can be used. This allows for the bonding of multiple layers, such as cardboard with a foil. Matte, glossy, or textured foils can be used. This makes the surfaces more durable. Embossing / foil stamping can be used, particularly flat or textured embossing. Lamination or sealing can also be used for finishing.

[0051] Furthermore, it is proposed that the material grip body of the grip unit comprises at least one layer of a paper material, which is formed in a rolled form. This allows for the advantageous production of a grip body. In particular, a grip body that is advantageously stable and easy to manufacture can be provided. Preferably, the layer of paper material is rolled around a defined rolling axis. The rolling axis preferably runs parallel, and in particular substantially coaxially, to a longitudinal axis of the grip unit. In particular, the layer is rolled during the production of the material grip body. Preferably, the layer forms a roll, especially a cylindrical roll, in a final state, particularly after production. Preferably, the layer has a helical cross-section at least partially, and in particular completely, in a plane perpendicular to the longitudinal axis of the grip unit.A large area of ​​the layer extends around a longitudinal axis of the handle unit. It is also conceivable that the layer, particularly within the roller, has a cross-section other than a spiral. For example, it is conceivable that the layer within the roller, especially in the core, has a triangular cross-sectional shape for further stiffening.

[0052] Furthermore, it is proposed that at least one layer of the handle material is rolled into a cylindrical shape. This allows for the advantageous production of a handle body. In particular, a more stable and easily manufactured handle body can be provided. An advantageous handle shape can also be provided. Preferably, the at least one layer of the handle material is rolled into a hollow cylindrical shape. The cylindrical shape can, in particular, have a base shape other than a circle. For example, it would be conceivable for the cylindrical shape to have an oval, regular or irregular n-sided (e.g., triangular, 4-, 5-, 6-, 7-, 8-sided, square, rectangular, trapezoidal, and / or rhombus-shaped base. The cylindrical base shape can also have concave sections / elements.It would also be conceivable for the base material to have several layers, which are rolled together into a cylindrical shape. In this context, "cylindrical shape" is understood to mean, in particular, the shape of a body with two opposing, essentially identical bases, which are connected by a shell and form a body. Preferably, the handle body has at least the essential shape of a circular cylinder or a hollow cylinder. The cylinder can also be twisted in a helical fashion. In this context, "at least the essential shape" 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.

[0053] Various configurations of the personal care product are conceivable, particularly those deemed sensible by a specialist. The handle material can be manufactured from one or more sheets of paper material and / or unwound from rolls, and / or be rolled from strips or a band. The layers of the handle material can be bonded together, for example, by gluing, sealing, welding, and / or laminating. Furthermore, it is conceivable that at least one layer is pre-treated before processing. Embossing, for example, is a possible pre-treatment to create a texture on the surface of the final product. Alternatively or additionally, coating the paper material is a conceivable pre-treatment. For instance, the inner surface of each layer of the paper material could be designed for bonding, while the outer surface would provide protection against moisture.Each layer can therefore have two sides with different treatments or coatings. Alternatively or additionally, printing is conceivable as a pretreatment. Furthermore, it is conceivable that at least one layer is post-treated after manufacturing. Post-treatment could include, for example, coating, printing, and / or laminating. Alternatively or additionally, post-treatment could involve deformation, particularly using pressure and heat, for example, to create a gripping geometry.

[0054] Preferably, the paper material can be rolled into either a solid or a hollow roll. In the case of a hollow roll, it is particularly conceivable that the roll is additionally filled, at least partially, with a filler material, such as a bulk material and / or a core made of paper or another material. To produce a hollow roll, especially a hollow handle, paper strips are unwound from rolls and formed together into a tube or, as defined above, a hollow cylinder. The paper strips are wound onto a core and then bonded to it. The process essentially corresponds to the process for producing paper drinking straws.The application unit, particularly with a plastic head and / or an interdental brush, is manufactured with an interface to the hollow tube and can be mounted directly onto the tube of the material handle body. It would also be conceivable for the application unit to be designed as an interchangeable head, with the interface integrated within the application unit between a connecting section with the material handle body and the cleaning unit. A particular challenge lies in achieving sufficient stability and a secure mounting capable of absorbing the forces exerted during use of the personal care product. Preferably, however, if the application unit is designed as an interchangeable head, a handle unit with various application units can be provided.Furthermore, a tube made of a paper material is a particularly simple standard product and can therefore be manufactured advantageously and cheaply.

[0055] The handle material can be rolled in a straight or spiral shape. Different strips can have different properties, such as different colors to achieve a spiral appearance. The handle material has a (maximum) diameter of 1 mm to 25 mm, preferably 1.5 mm to 20 mm, and particularly preferably 2 mm to 18 mm. Optionally, in addition to the paper tube, the handle material can also be provided with a plastic head, which, for example, prevents or at least reduces the ingress of water into the paper material and / or into a cavity within the paper layers. For this purpose, the end face of the paper material and any cavities should be particularly well protected.

[0056] Furthermore, the personal care product can be designed as a toothpick, interdental cleaner, or dental stick. This product can consist of a tube or rod made of a paper material, which is mechanically processed or shaped, for example, by being cut at an angle to form a toothpick. To manufacture the product, paper strips are unwound from rolls and formed into a tube. The paper strips are unwound onto a core and then bonded to it. Subsequently, one end of the tube can be cut at an angle and / or pointed to create the application unit. Other methods described in this document can also be used to form a roll or cylinder.

[0057] The application unit is specifically designed as a single piece with the handle unit. Optionally, at least part of the surface of the personal care product could be post-treated. Possible methods include printing, dipping, spraying, etc. For example, the personal care product could be varnished to reduce water absorption or printed on. Adequate water resistance is particularly important since the application unit is made of paper. Personal care products can also be applied. Naturally, other finishing processes, the use of fillers, or treatments of the paper material described in this document can also be applied.

[0058] It is further proposed that the handle body of the handle unit comprises at least two layers of a paper material, bonded together in a layered fashion. This allows for the advantageous production of a handle body. In particular, a suitably stable and easily manufactured handle body can be provided. An advantageous handle shape can also be provided. Preferably, the handle body, and especially the entire handle unit, consists of the at least two layers. Preferably, the at least two layers are arranged at least partially one above the other and bonded together. Preferably, 2 to 6, and more preferably 2 to 4, layers are provided. The layers can consist of different paper materials, with different densities or basis weights. Additional layers of films, especially plastic films, can be provided.Preferably, the at least two layers are arranged at least partially one above the other and connected to each other perpendicular to a principal plane of extension of the layers. The at least two layers abut each other, in particular, with a maximum surface area. The layers can be connected to each other, for example, by gluing and / or sealing and / or pressing and / or welding and / or laminating. The layers are connected to each other, in particular, during the manufacture of the personal care product. A "principal plane of extension" of an object is understood to be, in particular, a plane that is parallel to a maximum side face of the smallest imaginary cuboid that just completely encloses the object and passes through the center of the cuboid.

[0059] Preferably, the handle material is layered from sheets, rolls, or panels. Furthermore, it is conceivable that the at least two layers are pretreated, printed, or finished before processing (see the additional details in this document). The pretreatment, such as embossing, printing, or finishing, can also apply to only one layer. For example, embossing is also conceivable as a pretreatment, with the aim of creating a structure on the surface of the final product. Furthermore, as described, cavities can also be formed between the layers of paper materials by embossing the paper material. For example, with two layers at the same position on the handle, two opposing embossings are applied before the paper material layers are bonded, in order to create a handle that is at least partially three-dimensional instead of flat.

[0060] Alternatively or additionally, coating is conceivable as a pretreatment. For example, an inner surface of each layer of the sheet paper material could be designed for bonding, while an outer surface provides protection against moisture. Each layer can therefore have two sides with different coatings or properties. Alternatively or additionally, printing is conceivable as a pretreatment. Furthermore, it is conceivable that the at least two layers of the sheet paper material are post-treated after bonding. Post-treatment could include, for example, coating, printing, coating the application unit, and / or laminating. Preferably, the application unit is directly bonded to the material handle body. In particular, the application unit is inserted between the layers of the material base body and bonded together with the layers of paper material. For example,Welding, sealing, laminating, gluing, or other joining techniques are suitable. The application unit is essentially clamped between the layers to be joined. This application unit can be, for example, an interdental brush, dental floss, a tape, a film, a toothpick, or another personal care product. When joining the two flat paper layers, the overlapping part of the application unit displaces at least part of the paper, thus strengthening the bond. The overlapping part of the application unit can be deformed to further increase its hold within the paper.

[0061] A flosser would be a particularly suitable personal care product with a corresponding material base. Dental floss can be inserted into at least partially pre-cut sheets of the layers. In a manufacturing process, sheets or blanks made of paper material, which form the layers, are pre-cut. Pre-cutting occurs particularly in the area where the functional element is located. Blanks can also be formed during pre-cutting. Specifically, pre-cutting is performed on the areas of the material handle that cannot be cut after the functional element is mounted. Subsequently, the pre-cut sheet or blank made of paper material is prepared, and a thread, ribbon, or film is inserted.A thin film can be made of a stable, tear-resistant paper material, a plastic (especially a hard or soft component), or a sustainable plastic material. A further pre-cut sheet or panel of paper material is then placed over it, and the sheets or panels are joined, for example, by laminating, sealing, welding, and / or gluing. The personal care product, particularly its outer geometry, can then be die-cut into individual flossers or panels of flossers, and any excess thread, tape, or film can be removed.

[0062] It would also be conceivable to omit this step and directly die-cut the shape instead of pre-cutting, ensuring the thread, tape, or film does not protrude beyond the final outer geometry. The thread, tape, or film can be anchored in various ways deemed appropriate by an expert. For example, it can be anchored by attaching it with adhesive. Alternatively or additionally, it can be anchored by welding. The thread, tape, or film can be welded between the layers. Alternatively or additionally, it can be anchored by slotted arms on the material handle body with a thread or tape inserted within them. For this purpose, a multi-layered structure is particularly suitable, with a slot in the middle layer to ensure the thread or tape rests against all layers in the anchoring area.The thread or tape is then guided through the slot. In particular, several slots can be provided, with the thread or tape being guided alternately through the slots, similar to weaving. Alternatively or additionally, anchoring can be achieved by means of foldable tabs on the base material. Preferably, the base material has arms, each with a lateral projection facing opposite each other. The thread or tape can be guided over the projection for anchoring, with each end of the thread or tape resting on a projection. The thread or tape is then welded, and the projections are folded, in particular such that the thread or tape is bent around a corner. This provides particularly advantageous stabilization.Subsequently, at least one additional layer is applied to each side so that the thread or tape rests against another layer in the anchoring area.

[0063] Alternatively or additionally, the thread, tape, or film can be anchored by deforming the paper material to create stabilizing structures. For example, a rake-like structure can be incorporated into the layers. This deformation can be carried out before or after joining. Alternatively or additionally, anchoring can be achieved by creating a structured surface for attaching the application unit. For example, ribbed and / or rough surfaces can be created by welding. Alternatively, suitable anchoring can be achieved by crimping or interlocking.

[0064] Alternatively or additionally, anchoring can be achieved by creating tension tabs. The thread or tape can be wrapped around these tension tabs. This prevents subsequent tearing, as the tension tabs are fixed between the layers. The tension tabs have a length of 5 mm to 30 mm, preferably 10 mm to 20 mm, and a width of 2 mm to 6 mm, preferably 3 mm to 4 mm. The tension tabs are positioned next to the space occupied by the thread or tape. Furthermore, the thread or tape can also be fixed at another point. For example, a dot of adhesive can be used for fixation. Alternatively, the thread or tape can be formed as a ring or loop, specifically as a closed ring without a defined end, thus eliminating the need for additional fixation to the tension tabs.The ring made from the thread or tape can be manufactured directly as a ring or by knotting. The paper material of the handle body is typically sealed during manufacturing, with the tension tabs being sealed in as well. It is also conceivable to combine various anchoring techniques, such as welding and surface texturing, slitting and welding, tension tabs and welding, tension tabs and gluing, or tension tabs, surface texturing, and welding. In particular, various joining techniques and / or combinations thereof that would appear sensible to a person skilled in the art are conceivable. However, the joining technique must, in particular, prevent the thread or tape from tearing out during use.Preferably, a suitable design can ensure that the flosser can be disposed of directly with the paper or cardboard collection.

[0065] The draw-out weight of the thread or tape, measured perpendicular to the longitudinal extent of the thread / tape, is at least 10N.

[0066] An interdental brush would be a particularly suitable example of a personal care product with a suitable material base. In the first step of manufacturing, an interdental brush application unit can be provided. Subsequently, or concurrently, a sheet of paper material can be provided. The interdental brush application unit is then placed on the paper sheet, forming at least the first layer, and then another paper sheet, forming the second layer, is placed on top. The layers are then joined, for example, by welding, sealing, laminating, or gluing, and the handle is die-cut and / or, in the case of groups of products, partially die-cut and partially perforated. The products, especially if designed as interdental brushes, can also be produced on a longer sheet or...The strips are arranged and connected via a perforated section. Two to 24, preferably four to 16, and particularly preferably six to 12 interdental brushes are provided per unit. In another embodiment, the strip can also be rolled into a longer band or folded flat so that it can be inserted into a slit outer packaging, which serves as a dispenser. One product at a time can be pulled out or unwound and separated. The remaining products thus remain protected in the dispenser.

[0067] Optionally, a stand could be provided by unfolding the layers of the flat paper material. The layers could be separated by the end user via perforations and / or slits, allowing the user to easily bend them apart. Alternatively, the layers could be partially unconnected, enabling the end user to pull them apart section by section. These solutions can be used to create a stand and / or, as mentioned, to separate the layers, thus allowing the interdental brush to be separated from the paper material for disposal. This allows the paper material to be disposed of separately in the paper recycling and the application unit (interdental brush) in the regular household waste.

[0068] Optionally, protruding areas and / or thinning of the layers caused by material displacement of the paper base, which occur when the layers are joined by the twisted wire, can be avoided by inserting an interlayer, in which the twisted wire lies in a correspondingly pre-cut recess in the interlayer. The interlayer does not completely cover the upper and lower layers.

[0069] Optionally, the twisted end of the brush can be deformed to increase the pull-out force of the twisted wire from the paper material. In particular, the end of the twisted brush can be deformed for this purpose. This improves the grip in the paper material and distributes the force during application. The deformation of the application unit is particularly pronounced transversely to the longitudinal direction, for example, in an L-shape or S-shape, a wave-like shape, or a coat hanger-like form, with the deformation running along two sides of the twisted brush. The deformation of the twisted wire increases the pull-out force from the handle body. The pull-out force of the twisted wire from the paper-based handle body is between 1.5 kg and 6 kg, preferably in the range of 3 kg to 4.5 kg.

[0070] If the personal care product is designed as an interdental cleaner, it would also be conceivable for the application unit to be manufactured from plastic using an injection molding or extrusion process, with the design and / or manufacturing otherwise corresponding to that of the personal care product when designed as an interdental brush. Optionally, the application unit of the interdental cleaner can be a defined interface structure that incorporates means for anchoring between the flat paper material layers. Furthermore, the application unit of the interdental cleaner can optionally be inserted between two layers of paper material or mounted on layers of paper material.

[0071] If the personal care product is designed as an interdental cleaner, the application unit could be made of a paper material, particularly rolled paper, an organic material, or wood or bamboo. Otherwise, the design and / or manufacture of the personal care product corresponds to that of an interdental brush, as described above. Furthermore, the application unit of the personal care product could be mounted on the base material. For example, a flosser with a suitable base material could be considered, with the dental floss thread sewn to at least one layer of the base material. In particular, it is conceivable that the dental floss thread is sewn onto the first layer, using the floss thread as the sewing medium.Alternatively or additionally, the dental floss thread can be sewn on, with another thread being used to secure it. Preferably, in such a connection, 1 to 6, and more preferably 1 to 3, layers are provided. The paper material of the layers is provided in a thickness suitable for direct use, eliminating the need for further bonding processes to form the carrier. The layers have a material thickness of 0.5 mm to 2 mm, preferably 0.5 mm to 1.5 mm, with a density of 180 g / m² to 500 g / m², preferably 240 g / m² to 400 g / m², particularly to allow for sewing. In the manufacture of a personal care product, especially in the case of a flosser, the application unit can therefore be sewn onto the material handle.In a first process step, a sheet of paper material, forming the first layer, is at least partially die-cut. Specifically, at least those areas of the handle material in which the application unit is located are die-cut. Areas that cannot be die-cut after the dental floss thread of the application unit is mounted are also die-cut. The die-cut sheet is then prepared, and the dental floss thread is prepared and sewn on. The sewing can be done either with the dental floss itself or with an additional thread. If the dental floss thread is used as the sewing medium, it is sewn at both ends, particularly at the arms of the handle material, with the area of ​​the floss stretched between the ends serving as the application area. Optionally, further layers of paper material may be provided.For example, a further sub-layer can be bonded or folded onto a first sub-layer to create multiple layers. The handle material can, in particular, have a hinge at the top of the arms. This helps prevent injuries. Furthermore, the stitching could be used as a visual design element. Alternatively or additionally, laminating the layers could also serve as a finishing layer. Alternatively or additionally, the application unit could be attached using adhesive or injection molding. However, the bonding technique must prevent the thread from tearing during use. Sewing requires only one stamping step, but concealing the floss ends is particularly difficult.

[0072] One option in particular is conceivable where the number of layers varies. For example, more layers could be present in the anchoring area, where a certain level of stability is required, than on the rest of the handle – or vice versa. Not every layer necessarily needs to extend over the entire area of ​​the adjacent layer. A reduced layer can be located on the outside or positioned between larger layers. Positioning it between layers prevents damage from tearing. In particular, there are no external, potentially dangerous edges that could pose a risk of injury.

[0073] It is further proposed that the material grip body of the grip unit comprises at least one layer of a paper material, which is at least partially folded. This allows for the advantageous production of a grip body. In particular, a grip body that is advantageously stable and easy to manufacture can be provided. An advantageous grip shape can also be provided. Preferably, the layer is made of a continuous, especially pre-cut, piece of paper and / or cardboard. The layer advantageously comprises at least one fold axis and / or at least one fold edge. In a state of use, the layer is preferably folded along the at least one fold axis and / or the at least one fold edge. Advantageously, the at least one fold axis and / or fold edge facilitates folding the layer into a state of use.It would be conceivable for the layer to be perforated and / or embossed along the fold line and / or axis to allow for defined folding. Preferably, the layer is divided into two sides, particularly sub-layers, by the at least one fold line. Preferably, the at least one fold line and / or fold line runs parallel to the main direction of extension of the personal care product. It is also conceivable for at least one fold line to run perpendicular to the main direction of extension of the personal care product. The handle material can be folded, in particular, from sheets of paper or from a roll. Furthermore, the folded sides can be joined, in particular, by sealing or gluing. As a pretreatment, embossing, for example, is conceivable with the aim of creating a structure on the surface of the final product. Alternatively or additionally, coating is conceivable as a pretreatment.For example, one inner side of a layer could be designed for bonding, while the other side provides protection against moisture. The layer can therefore have two sides with different pretreatments, such as coatings. Alternatively or additionally, printing is conceivable as a pretreatment. Furthermore, it is conceivable that at least one layer is post-treated after manufacturing. Post-treatment could include, for example, coating, printing, and / or laminating. Preferably, the layer of the material handle body is cut or die-cut.

[0074] A toothbrush would be a particularly conceivable example of a personal care product with a suitable basic material. This product would be flat, with grooves designed to facilitate folding before first use. These grooves would be positioned along the fold axis. Alternatively, folding could be combined with a joining process such as gluing, sealing, welding, bonding, or laminating. For a toothbrush-shaped product, the structure could be origami-inspired, forming a paper framework. Alternatively, or additionally, the toothbrush could incorporate cleaning elements made of a paper-based material.

[0075] A toothpick or interdental cleaner would be a particularly suitable personal care product with a corresponding material base. The personal care product is made of a sheet paper material, with grooves specifically designed for folding before first use. The grooves are arranged along the folding axis. During use, the personal care product can be folded into a triangle, pyramid, or cone shape. The paper material preferably used for manufacturing a personal care product in the shape of a toothpick is tracing paper. This tracing paper is preferably made from virgin pulp (wood-free). For the aforementioned application, the tracing paper has a basis weight of 150 g / m² to 300 g / m², preferably 200 g / m² to 250 g / m².Optionally, a folded personal care product could also have an inner framework made of paper material, while an outer shell surrounds the framework.

[0076] According to the invention, it is proposed that the application unit comprises at least one cleaning element carrier, in particular wire, and several cleaning elements connected to the cleaning element carrier, in particular twisted into it, wherein the cleaning element carrier is connected to the handle body by a connecting section facing away from the cleaning elements. This allows for a particularly advantageous connection of the personal care product. In particular, the number of elements of the personal care product can be kept to a minimum. Preferably, the cleaning elements are formed by bristles. Preferably, the cleaning element carrier is directly coupled to the cleaning elements and directly coupled to the handle body. The cleaning element carrier is in particular formed in one piece, preferably as a single unit. "In one piece" is understood to mean formed in one piece.Preferably, this single piece is manufactured from a single blank, a mass, and / or a casting, particularly preferably using an injection molding process, especially a single- and / or multi-component injection molding process. Particularly preferably, the cleaning element carrier is connected in a connecting section, especially directly, to a paper material of the handle body.

[0077] Furthermore, it is proposed that the connecting section of the cleaning element carrier of the application unit projects into and is enclosed by the material handle body. It is particularly proposed that the at least one cleaning element carrier of the application unit be formed by being rolled into at least one layer of the material handle body at a connecting section facing away from the cleaning elements. This provides a particularly advantageous connection between the application unit and the handle unit. Alternatively, the cleaning element carrier of the application unit can be inserted into a cavity in the material handle body at a connecting section facing away from the cleaning elements. The cavity can be provided during the manufacture of the material handle body by means of rolling, embossing, etc., or created by mechanical means.The cavity is created by displacement, (mandrel) drilling, or similar methods. Preferably, the application unit is directly connected to the handle body via the connecting section. In one embodiment, the application unit can be connected to the handle body in a connecting section while the handle body is being rolled. The connecting section of the application unit is, in particular, rolled into the handle body. In a second embodiment, the application unit can be connected to the handle body in the connecting section after the handle body has been rolled. The application unit can be connected to the handle body, in particular, by inserting and / or attaching it to the handle body. As mentioned, it is possible to pre-machine the rolled handle body to create the necessary space for the connecting section.In a third variant, the application unit can form at least part of the rolled area of ​​the material handle body. The application unit can, for example, be an interdental brush, a toothbrush head, or a toothpick.

[0078] The fixing of the connecting section in the application unit is carried out using known methods such as welding, sealing, gluing, pressing, laminating, etc.

[0079] Alternatively or additionally, the connection section of the application unit can be designed as an interface for an interchangeable part, such as an interchangeable head for a manual toothbrush.

[0080] The handle material can be either straight or spirally rolled. It is also conceivable that the base material is rolled like a paper stump, particularly a so-called blending stump. The handle material, designed as a roll, has a (maximum) diameter of 1 mm to 25 mm, preferably 1.5 mm to 20 mm, and most preferably 2 to 18 mm.

[0081] An interdental brush would be particularly advantageous as a personal care product with a suitable material base. The paper can be rolled simultaneously as the brush is being formed. This would allow for the direct production of finished interdental brushes from the machine. One possible manufacturing process involves first forming the interdental brush head by rolling it into the brush head. In a second step, at least one layer of the brush head is rolled, and simultaneously, a connecting section of the brush head is rolled into the brush head. The brush head can be anchored to the brush head using adhesive, welding, or crimping. This may require an additional step.In a second variant for manufacturing the personal care product, the first step involves producing the application unit, in the form of an interdental brush, by screwing it together. Simultaneously, the handle is produced by rolling at least one layer of material. In a second step, the handle is then prepared for connection with the application unit. This involves, for example, creating a hole in the handle. This can be done by drilling a hole in the end face of the handle or by displacing the material with a mandrel. However, it would also be conceivable to create the hole during the manufacturing process of the handle itself, for example, by leaving a cavity (hollow cylinder). In this case, the second step (mechanically forming a hole) could be omitted.Subsequently, in a further process step, the application unit is anchored in a recess in the material handle body, for example by gluing, welding, pressing, sealing, or similar methods. In a third variant for manufacturing the personal care product, the application unit, in the form of an interdental brush, is first produced by screwing it in. Simultaneously, the material handle body is produced by rolling at least one layer, with the material handle body being manufactured particularly as a hollow tube. The application unit is then anchored in the recess in the material handle body in a further process step, for example by gluing, welding, pressing, or similar methods. The application unit can, in particular, be inserted and anchored directly into the central hole of the tube.

[0082] Optionally, the handle body can already be made from a printed paper material. This would allow for a colored end product to be created without any further processing.

[0083] Alternatively or additionally, the ends of the handle could be sealed. Sealing the exposed sides would create a tight seal, preventing water from penetrating the edges of the paper material. This could be achieved by providing a top and / or bottom cover. The cover could be an integral part of the application unit or connecting section. Alternatively or additionally, the ends of the handle could be crimped or treated with water-repellent substances such as wax, varnish, or similar materials.For example, in the case of a sealing process, it would be conceivable that a filler, such as wax, is already applied to the paper material, and that only the ends of the handle material need to be heated for sealing. A particular challenge could be creating a stable interface between the paper material and the application unit.

[0084] In the case of a body care product being designed as an interdental cleaner, it would also be conceivable that the application unit is manufactured using an injection molding process, whereby the structure and / or manufacture otherwise corresponds to the structure and / or manufacture of the body care product when designed as an interdental brush.

[0085] According to the invention, it is proposed that the at least one cleaning element carrier of the application unit is bent to form an at least partially positive-locking connection with the handle unit in the connecting section. Preferably, the at least one cleaning element carrier of the application unit is bent to form an at least partially positive-locking connection with the handle unit in the connecting section between two layers of the material handle body, which are particularly layered and bonded together. This prevents the cleaning element carrier from tearing out. In particular, a more stable personal care product can be provided. An interdental brush would be a particularly suitable personal care product with such a connection. For this purpose, the end of the twisted brush can be provided with a deformation.This improves the grip on the paper material and distributes the force during application. The application unit is deformed primarily transversely to the longitudinal direction, for example, into an L-shape, S-shape, wave shape, or coat hanger-like form, with the deformation occurring on two sides of the twisted brush. Alternatively or additionally, the connecting section could extend through the entire material of the handle body, allowing the handle body to be bent into a desired shape, particularly if made of wire. The connecting section can then be used as a shaping or adjusting element, for example, to give the handle unit a non-planar or three-dimensional shape, such as a curve, a twist, an angle, etc.Alternatively or additionally, it would be conceivable to place a wire loop in the handle body using the connecting section, creating a ring-shaped elevation on the handle body that can be used, for example, as a thumb grip.

[0086] Furthermore, it is proposed that at least one cleaning element carrier of the application unit be at least partially bonded to the material handle body, in particular by means of gluing, sealing, lamination and / or welding. This prevents the cleaning element carrier from tearing out. In particular, this results in a more stable personal care product.

[0087] Furthermore, it is proposed that the application unit comprise at least one cleaning element made of paper material. This cleaning element can be formed, in particular, by individual bristles or a bundle of bristles, as well as by dental floss, a dental floss tape (especially interdental tape), a film, or the like. Various designs of the cleaning element that would appear sensible to a person skilled in the art are conceivable. For example, the handle unit and the application unit could be made from the same paper material or sheet of paper. A solid handle unit and a loose bristle field for the application unit can be produced by folding, rolling, and fixing. Alternatively, the application unit can be layered and glued, with the cleaning elements die-cut from a single sheet.The cleaning elements can consist of mechanically processed paper material, for example, the paper material can be slotted, cut, separated, punched, pressed, compacted, etc. Any slots in the paper material can be spaced or spaced apart. However, a lateral gap is particularly important to allow for lateral movement of the cleaning elements. This is achieved, in particular, by using various slotted and unslotted layers, or even reduced layers stacked on top of each other. Furthermore, a hybrid solution would also be conceivable, for example, using paper and plastic, as is already used in yogurt cups. A variant with paper on the inside and plastic on the outside would also be possible.

[0088] This allows for the provision of a particularly environmentally friendly personal care product. In particular, it enables the product to be disposed of in a particularly easy and advantageous manner.

[0089] Furthermore, it is proposed that at least one cleaning element be at least partially formed by a film or tape, which can be designed as an interdental cleaning agent. The cleaning element is specifically formed by a tape or interdental tape. Preferably, the application unit, in particular the cleaning element, is formed by an interdental cleaner made of a film-like structure, such as one based on plastic and / or paper. The base material can be, in particular, a tear-resistant paper, a plastic film such as a plastic monofilm or composite film (i.e., in particular several bonded monofilms), a sustainable and / or biodegradable material such as PLA, and / or a nonwoven fabric such as Tyvek from duPont. The interdental cleaner is used in the same way as the dental floss described above.The interdental cleaner is bonded to the handle unit, particularly between layers of the handle material. The product structure may, in particular, have at least three layers, at least in some sections: a first layer of paper material, a second layer formed by the interdental cleaner, and a third layer of paper material. The personal care product is not entirely three-layered and / or does not have the same number of layers throughout. The interdental cleaner is only incorporated in a partial area. The interdental cleaner may also be mechanically processed. The interdental cleaner may be embossed, particularly to create surface textures and topography. The interdental cleaner may be folded for use.Furthermore, the interdental cleaner can be formulated with additives such as antibacterial agents, cleaning agents (especially oral hygiene cleaners), flavorings, and / or abrasives, such as granules to aid cleaning. The abrasive can also be used to create a surface texture. Additionally, the interdental cleaner may have various edges with different shapes. The interdental cleaner has a thickness of 0.05 mm to 0.5 mm, preferably 0.15 mm to 0.35 mm. Furthermore, the interdental cleaner has a width or height of 0.5 mm to 10 mm, preferably 1 mm to 6 mm. The length is adapted to the available space in the application unit.

[0090] Furthermore, it is proposed that the application unit be arranged between the at least two layers of the handle body. The application unit is, in particular, an interdental brush, dental floss, and / or an interdental cleaner. This allows for a particularly advantageously compact and stable design.

[0091] Furthermore, it is proposed that the personal care product has a plug-in connection unit that provides a detachable connection between the application unit, which is designed in particular as a toothbrush head, and the handle unit. It would also be conceivable for the application unit to be designed as an interchangeable head, with the plug-in connection unit arranged directly between the application unit and the handle unit. The plug-in connection unit is, in particular, at least partially integrally formed with the application unit and / or at least partially integrally formed with the handle unit. Preferably, the plug-in connection unit has at least one first plug-in element that is fixedly connected to the handle unit, and at least one second plug-in element corresponding to the first plug-in element, which is fixedly connected to the application unit.The plug-in connection unit allows, in particular, the application unit to be separated from the physical handle body. The plug-in connection unit is specifically designed to provide a detachable or permanent locking connection. The first plug-in element forms a locking projection, while the second plug-in element forms a locking recess corresponding to the first plug-in element. However, a reversed and / or other embodiment of the plug-in connection unit, which would appear sensible to a person skilled in the art, would also be conceivable.

[0092] Furthermore, it is conceivable that the basic material body of the handle unit is at least partially assembled from several paper-based components. For this purpose, a paper-based material is cut into components, which are then joined together. In a basic process, a paper-based material is cut into various shapes, then joined together and optionally secured or connected. The connection can be made, for example, by inserting, gluing, and / or welding. As a pretreatment, embossing is conceivable, for example, with the aim of creating a structure on the surface of the final product. Alternatively or additionally, coating is conceivable as a pretreatment, with the outer surface providing protection against moisture. Alternatively or additionally, printing is conceivable as a pretreatment.Furthermore, it is conceivable that at least one layer is post-treated after manufacturing. Post-treatment could include, for example, coating, printing, and / or laminating. This post-treatment can occur after the manufacturing of the individual components or after their assembly. In particular, previously described, especially flat, handle bodies, such as the previously described flossers, can be provided with at least one additional component that essentially rotates in another direction, particularly perpendicular to a main plane of extension, and thus creates a 3D effect. Alternatively, the personal care product can be designed as a toothbrush, where, for example, a plastic part serves as the base body with geometries that allow for its combination with pieces of paper material.This allows for the provision of a particularly advantageous three-dimensional handle unit, while minimizing material usage. Preferably, in the case of a toothbrush, the application unit can be designed with a brush head and a neck extension made of plastic, to which the material handle body with its components is attached. The personal care product can consist of, in particular, 2 to 25, preferably 4 to 12, individual parts.

[0093] When designing a body care product as a flosser, it is particularly conceivable that various flat pieces of paper material, especially for the handle unit, are cut and then assembled to form a 3D contour. During manufacturing, the application unit and the handle unit components are produced separately. The body care product can be assembled either during production or by the user. User assembly allows for a particularly advantageous reduction in the product's packaging size. Several design variations are conceivable. In particular, a network of components without a core can be formed, or a core can be provided onto which the components are attached.In this context, the necessary stability of the connections must be ensured with regard to the application. In particular, separation, for example through undercuts, must be avoided.

[0094] In the case of the body care product being designed as an interdental cleaner, it would be particularly conceivable that the application unit is manufactured in an injection molding process, with the application unit being attached to an assembled handle unit made of paper material.

[0095] Furthermore, it is proposed that the personal care product be milled at least partially from a paper-based material. In particular, the personal care product is manufactured at least partially from solid board, which is milled into a defined shape. It is especially conceivable that the solid board is post-treated after milling. Post-treatment could include, for example, coating, printing, and / or laminating. Preferably, at least the handle unit is made of solid board. Various solid boards that would be suitable for a person skilled in the art are conceivable, such as, in particular, Finnish board. In this context, a die-cut toothbrush would be a particularly conceivable personal care product. For this purpose, a block of paper-based material is milled into a contour, with holes drilled in the future brush head.In the manufacturing process, the handle unit and parts of the application unit are milled and drilled from a block of paper-based material in the first step. The handle unit and / or the application unit can then be optionally printed and varnished. Next, bristle bundles for the application unit are punched out, inserted, and profiled. A defined pull-off weight for the bristle bundles must be ensured. Alternatively, the bristle bundles could be attached using an aerated profile technology (AFT). For this, the handle unit and parts of the application unit are milled from a block of paper-based material. A recess is created in the future brush head of the application unit. Simultaneously, a bristle plate is produced, which can then be anchored in the recess.In the manufacturing process, the handle unit and parts of the application unit are milled from a block of paper-based material in a first step. A recess is simultaneously milled into the brush head of the application unit. The handle unit and / or the application unit can then be optionally printed and varnished. Next, a bristle plate is injection-molded and fitted with bristles. The finished bristle plate is then inserted into the brush head of the application unit and secured by crimping and / or gluing. It is particularly important that the bristle plate is reliably bonded to the paper-based material.

[0096] Furthermore, it is proposed that the personal care product be molded, at least partially, from a paper material. The paper material is processed using a process similar to injection molding. However, the processing of the paper material is carried out at significantly lower temperatures and injection pressures. Similar processes are known, for example, from PurePaperPak, a structural paper packaging. This allows for the use of particularly environmentally friendly raw materials, with the ingredients being of natural origin and, in particular, consisting of 100% natural resources. The raw materials consist primarily of industrial starch, preferably from potatoes, paper fibers, and water, including any additives. The resulting paper mixture is then used for further processing using injection molding technology. Paper injection molding is carried out in three steps.The first step involves injection, where the paper mixture is injected into an aluminum mold. The second step is a baking process, in which the paper mixture is baked, specifically heated, within the mold. The third step is demolding, allowing the finished packaging to be removed. Furthermore, so-called PAPACKS®< packaging is available. This packaging consists primarily of food-grade PAPACKS®< fiber casting. Such products are compostable and can be recycled with waste paper or organic waste. It is conceivable that the molded personal care product could undergo post-treatment after molding. This post-treatment could include coating, printing, and / or laminating. A die-cut toothbrush would be a particularly suitable example of a personal care product in this context.A toothbrush body, in particular the handle unit and parts of the application unit, is cast from a paper material, and bristle holes are formed, preferably analogous to modern injection molding. In a manufacturing step, the handle unit and parts of the application unit are cast from a paper material. The handle unit and / or the application unit can then optionally be printed and varnished. Following this, bristles of the application unit are punched out, inserted, and profiled.

[0097] It is further proposed that the paper material of the personal care product, in particular the handle unit, be overmolded, at least in sections. The paper material can be designed according to one of the embodiments mentioned above. The paper material of the personal care product, in particular the handle unit, is in particular overmolded with a plastic. A connection between the overmolding and the paper material can be achieved, in particular, by undercuts, perforations (i.e., a positive fit), or chemically, in particular by a material bond. The paper material can be pretreated for this purpose, in particular before overmolding, to enable the bonding, for example, by means of special varnishes and / or coatings. A cleaning unit of the application unit can, for example, be created, at least partially, by overmolding.In particular, a perforated area or a recess for a bristle plate can be created in a brush head of the application unit by means of overmolding. Alternatively or additionally, injection-molded bristles can be provided, which are produced directly by overmolding. A toothbrush would be a particularly conceivable personal care product in this context. For this purpose, a cardboard tube is overmolded, with a brush head being directly injected onto the cardboard tube. In the manufacturing process, a cardboard tube is produced in a first step, forming the handle unit. Subsequently, the cardboard tube is overmolded, with the application unit being formed with a perforated area. Bristles are then punched into the perforated area, inserted, and profiled. Alternatively, a flosser would be a particularly conceivable personal care product in this context.For this purpose, a cardboard tube is overmolded, with a flosser head being directly injected onto the cardboard tube. In the manufacturing process, a cardboard tube forming the handle unit is produced in a first step. The cardboard tube is then overmolded, with the application unit, in the form of a flosser head, being formed. Alternatively, an interdental cleaner could be considered as a personal care product in this context. For this purpose, a cardboard tube is overmolded, with an interdental cleaner being directly injected onto the cardboard tube. In the manufacturing process, a cardboard tube forming the handle unit is produced in a first step. The cardboard tube is then overmolded, with the application unit, in the form of an interdental cleaner, being formed.Furthermore, a handle unit with an interface for changing the personal care product can be provided. In the manufacturing process, a cardboard tube, which forms the handle unit, is produced in a first step. The cardboard tube is then overmolded, creating an interface to an application unit. The application unit is equipped with the counterpart to the interface and can therefore encompass a wide variety of applications, such as flossers, toothbrushes, and interdental cleaners.

[0098] It is further proposed that the personal care product has at least one functional part that is overmolded with a paper material. This functional part can be formed, in particular, by a core of the handle unit and / or the application unit, which is manufactured using a known process, such as plastic injection molding. The overmolded material can be connected to the functional part, in particular, by undercuts, perforations (i.e., a positive fit), or chemically, in particular by a material bond. The functional part can be pre-treated, especially before overmolding, to facilitate the bonding, for example, by means of special lacquers and / or coatings. In this context, an interdental cleaner or a toothbrush would be a particularly suitable example of a personal care product.For this purpose, in particular the application unit and / or parts of the handle unit are manufactured in a plastic injection molding process, wherein the application unit and / or parts of the handle unit are partially overmolded with a paper material.

[0099] Furthermore, it is proposed that the personal care product, in particular the handle material, has at least one layer that is at least partially deformed and / or pressed. This layer can be produced, in particular, from one or more sheets of paper material and / or from rolls. The personal care product has several layers. The layers, in particular those of the handle material, can be joined together, for example, by gluing, welding, and / or laminating. It is also conceivable that the layer is pretreated before processing. For example, embossing could be used as a pretreatment to create a structure on the surface of the final product. Alternatively or additionally, coating could be used as a pretreatment.For example, one inner surface of each layer could be designed for bonding, while the other outer surface provides protection against moisture. Each layer could therefore have two sides with different coatings. Alternatively or additionally, printing could be used as a pretreatment. Furthermore, it is conceivable that at least one layer undergoes post-treatment after manufacturing. Post-treatment options could include coating, printing, and / or laminating. In this context, a toothpick or flosser would be a particularly suitable example of a personal care product. However, an alternative general basic shape for a handle unit is also conceivable. The at least one layer of the personal care product is deformed, preferably deep-drawn, particularly using pressure and heat. This creates, for example, a grip geometry for improved ergonomics.In particular, a personal care product with a bulky handle unit can be provided. It would also be conceivable for the handle unit to consist of two joined, deep-drawn half-shells that, when connected, enclose a cavity. The half-shells can be joined, for example, by gluing, welding, and / or snapping them together. This is one way, for instance, to manufacture the handle unit of a toothbrush.

[0100] Optionally, the products can be grouped during the manufacturing process, particularly for personal care products. For example, a group of flossers, similar to current interdental cleaners, can be provided, which are then separated for use. The personal care products can be connected by the paper material, ideally with a perforation along which they can be separated. This simplifies processing, as the products are manufactured in groups and separated only upon use.

[0101] As an alternative to rolling paper material, extruding paper material to create a cylindrical structure would also be conceivable. As an alternative to milling paper material, turning paper material to create rotationally symmetrical geometries would also be conceivable.

[0102] Furthermore, it is conceivable that the personal care product could have functional cut edges and / or borders on the paper material. In particular, paper with different edges could be used, with the edges having functionally different properties. For example, one functional side could be corrugated, while a non-functional side could be smooth. However, the reverse design would also be conceivable. In particular, the cut edges could be treated afterward to prevent, for example, the risk of injury or water absorption. Specifically, mechanical post-processing to reduce sharpness could be provided, such as rounding the edges. Coatings of wax or varnish could also be applied.

[0103] Furthermore, a special surface can be created on the paper material. In particular, different surfaces can be created on different sides, for example in terms of color or surface texture.

[0104] Furthermore, it would be conceivable to incorporate folds for feet. In particular, the paper material could be folded at the end of the product so that the personal care product can be stored upright. A stand could be created, specifically.

[0105] Furthermore, flexibility can be achieved by reducing the material thickness in sections. In particular, bending edges can be created. A corresponding reduction in material thickness can be achieved, for example, by grooving in flat versions or by perforation.

[0106] According to the invention, a weld connection need not cover the entire contact surface. For example, tear-off tabs and / or certain edge positions can be left unwelded. Furthermore, welding can be performed only at the edge, while inner surfaces are omitted. It is also conceivable to omit welds, for example, to allow for flexibility. Alternatively, welding could be deliberately performed to create flexibility, particularly in the area of ​​a folding edge. Alternatively or additionally, welding can be performed only in the area of ​​the interface with the application unit, for example, only at the connection section of the cleaning element carrier.

[0107] When the personal care product is designed as an interdental brush, the handle unit is particularly lighter than a conventional plastic handle. An interdental brush with a rolled or layered handle body has a total weight of less than 2 g, preferably less than 1 g, and most preferably less than 0.6 g. A flosser with a layered handle body has a total weight of less than 2 g, preferably less than 1.2 g, and most preferably less than 0.8 g. The center of gravity of the interdental brush with a rolled or layered handle body is located, measured from the lower end, at 40% to 70%, and preferably at 45% to 60%, of its total length.

[0108] It is further proposed that the paper material have a water-repellent coating and / or impregnation. Such a coating and / or impregnation can also reduce the paper material's water absorption, making it suitable for multiple uses. Impregnation can be achieved, for example, using a plastic and / or wax or similar substances.

[0109] It is further proposed that the paper material be varnished and / or printed. This allows for particularly advantageous customization of the paper material. Printing on the paper material can be especially easy. A finishing effect can be achieved, for example, a varnish coating, such as UV high-gloss varnish, textured varnish, soft-touch varnish, or glitter varnish. Alternatively or additionally, the paper material can be printed. For example, the paper material can be printed on water-based varnishes, which are more environmentally friendly than conventional varnishes.

[0110] Furthermore, the invention relates to a method for manufacturing a personal care product. It is proposed that the material handle body of the handle unit be rolled onto at least one layer of a paper material. This allows, in particular, the production of a suitably stable handle body. Preferably, the layer of paper material is rolled around a defined rolling axis. The rolling axis preferably runs parallel, and in particular coaxially, to a longitudinal axis of the handle unit. Preferably, the layer is rolled, at least partially, and in particular completely, into a spiral cross-section in a plane perpendicular to the longitudinal axis of the handle unit. A major area of ​​the layer extends, in particular, around a longitudinal axis of the handle unit. Preferably, the at least one layer of the material handle body is rolled into a cylindrical shape.

[0111] Furthermore, it is proposed that the application unit be rolled into the material handle body in at least one connection section. This provides a particularly advantageous connection between the application unit and the handle unit.

[0112] It is further proposed that the handle body of the handle unit be constructed from at least two bonded layers of a paper material. This allows for the advantageous production of a handle body. In particular, a handle body that is advantageously stable and easy to manufacture can be provided. In one manufacturing process, sheets of paper material forming the layers are pre-cut. Pre-cutting is carried out, in particular, in the area where the functional element, especially the application unit, is located. Pre-cutting is specifically performed in those areas of the handle body that cannot be cut after the functional element is mounted. Subsequently, the pre-cut sheet is prepared, and a thread is inserted.A further pre-cut sheet is then placed over the first and the sheets are joined, for example by laminating, welding, and / or gluing. The personal care product, particularly its outer geometry, can then be fully die-cut, and any excess thread can be removed. Alternatively, this step could be omitted, and the product could be die-cut directly instead of pre-cutting, ensuring the thread does not extend beyond the final outer geometry.

[0113] It is further proposed that the application unit be glued and / or laminated into at least one connection section between the at least two layers of the material handle body. The application unit can be anchored in various ways that would appear appropriate to a person skilled in the art. For example, anchoring can be achieved by attaching the application unit using an adhesive. Alternatively or additionally, anchoring can be achieved by welding. The application unit can be welded between the layers.

[0114] The personal care product according to the invention is not to be limited to the applications and embodiments described above. In particular, the personal care product according to the invention may, to fulfill a function described herein, comprise a different number of individual elements, components, and units than specified herein 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.

[0115] Naturally, the embodiments shown in this document are merely examples. Within the scope of the invention, the individual features and elements of these embodiments can be combined with other embodiments without departing from the scope of this invention. Drawings

Description of the exemplary implementations

[0118] The Figure 1AFigure 1 shows a schematic perspective view of an application unit 12a of a personal care product 10a. The personal care product 10a is formed by an oral hygiene product. In this case, the personal care product 10a is designed as an interdental brush. The personal care product 10a can also be designed as a disposable toothbrush or as a toothbrush with replaceable heads. Furthermore, the personal care product 10a could be designed as a flosser, a single-tuft brush, an interdental cleaner, a tongue cleaner, or the like. Combined personal care products 10a 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 the like.

[0119] The personal care product 10a has the application unit 12a. Furthermore, the personal care product 10a has at least one handle unit 14a connected to the application unit 12a.

[0120] The following will refer to the Figures 1A to 1C Reference is made to the figures, which show different views and manufacturing stages of the personal care product 10a. Due to the different views, some elements are not shown in all figures and therefore not labeled with reference symbols in all figures.

[0121] The personal care product 10a has a longitudinal axis 30a and a vertical axis. The longitudinal axis 30a is arranged parallel to a principal extension direction 34a of the personal care product 10a.

[0122] The application unit 12a is located on the top of the personal care product 10a. The application unit 12a forms the uppermost point of the personal care product 10a.

[0123] The grip unit 14a is designed for gripping by the operator. The grip unit 14a has a cylindrical base shape. The grip unit 14a also has a material grip body 16a. The material grip body 16a forms a material volume of the grip unit 14a. The material grip body 16a has a cylindrical shape. The material grip body 16a of the grip unit 14a consists at least partially, and in particular at least predominantly, of a paper material. The material grip body 16a consists entirely of a paper material. The material grip body 16a of the grip unit 14a has at least one layer 18a of a paper material, which is formed in a rolled form. By way of example, the material grip body 16a has exactly one layer 18a; however, a multi-layered structure would also be conceivable. The layer 18a of the paper material is rolled around a defined axis of rotation.The rolling axis runs parallel, in particular coaxially, to the longitudinal axis 30a of the personal care product 10a. Layer 18a is rolled up during the manufacture of the material handle body 16a. In a final state, in particular after manufacture, layer 18a forms a roll, in particular a cylindrical roll. Layer 18a of the material handle body 16a is rolled into a cylindrical shape. Layer 18a of the material handle body 16a is bonded to itself within the roll by gluing, welding, and / or laminating. The paper material is rolled into a solid roll.

[0124] The material handle body 16a can be, in particular, straight or spirally rolled. The material handle body 16a has a diameter of 2 mm to 10 mm, preferably 3 mm to 7 mm. Optionally, in addition to the paper-based tube, the material handle body 16a can also be provided with a plastic head, which, for example, prevents the ingress of water.

[0125] Furthermore, the application unit 12a comprises a cleaning element carrier 22a and several cleaning elements 24a connected to the cleaning element carrier 22a, in particular twisted into it. The cleaning element carrier 22a is, by way of example, formed by a wire, with the cleaning elements 24a being formed by bristles twisted into the wire. However, another embodiment of the cleaning element carrier 22a and / or the cleaning elements 24a, which would appear sensible to a person skilled in the art, would also be conceivable. The cleaning element carrier 22a is connected to the handle unit 14a by a connecting section 26a facing away from the cleaning elements 24a and to the material handle body 16a. The connecting section 26a is, in particular, formed by a wire end facing away from the cleaning elements 24a.The connecting section 26a of the cleaning element carrier 22a of the application unit 12a projects, particularly in the manufactured state of the personal care product 10a, into the material handle body 16a and is enclosed by it. The application unit 12a is directly connected to the material handle body 16a via the connecting section 26a. The cleaning element carrier 22a of the application unit 12a is formed by being rolled into the layer 18a of the material handle body 16a at the connecting section 26a facing away from the cleaning elements 24a. The connecting section 26a of the application unit 12a is rolled into the material handle body 16a during the manufacturing process. The connecting section 26a of the application unit 12a is directly bonded to the material handle body 16a during the rolling of the layer 18a, particularly by bonding.The cleaning element carrier 22a of the application unit 12a is materially bonded, in particular by means of gluing and / or welding, to the material handle body 16a.

[0126] In particular, a method for manufacturing the personal care product 10a is disclosed. In this method, the material handle body 16a of the handle unit 14a is rolled from layer 18a of a paper material. Furthermore, the application unit 12a is rolled into the material handle body 16a in at least one connecting section 26a. A corresponding manufacturing process could, in one variant, proceed such that in a first step the application unit 12a, in the form of an interdental brush, is produced by twisting (see Fig. 1A). Subsequently, in a second process step, at least one layer 18a of the material handle body 16a is rolled and simultaneously the connecting section 26a of the application unit 12a is rolled into the material handle body 16a (see Fig. 1B The application unit 12a can be anchored in the material handle body 16a, in particular by adhesive, welding, or crimping. This may require an additional process step. A finished personal care product 10a is in the Figure 1C shown.

[0127] Furthermore, it is provided that the paper material of the handle body 16a has a water-repellent coating and / or impregnation. The appropriate coating and / or impregnation can also reduce the water absorption of the paper material. This makes the paper material suitable for multiple uses. Impregnation can be achieved, for example, using a plastic and / or wax or the like. It is also provided that the paper material of the handle body 16a is varnished and / or printed. In particular, a finishing treatment can be achieved. A finishing treatment can, for example, be a varnish, such as UV high-gloss varnish, textured varnish, soft-touch varnish, or glitter varnish. Alternatively or additionally, the paper material can be printed.The paper material can, for example, be printed with water-based varnishes, which are more environmentally friendly than conventional varnishes. Alternatively or additionally, it would also be conceivable that the ends of the material handle body 16a are pressed together or sealed with a wax, for example. In the case of sealing, it would be conceivable, for example, that a filler such as wax is already applied to the paper material and that only the ends of the material handle body 16a need to be heated for sealing.

[0128] Figure 1DFigure 1 shows an exemplary structure of layer 18a of the material handle body 16a. Layer 18a comprises several sublayers 68a, 68a', 68a" which form layer 18a. Layer 18a has a first sublayer 68a, which forms a base layer, in particular a carrier layer. The first sublayer 68a consists of a paper material, in particular paper. The first sublayer 68a has, in particular, a print 70a on an outer surface. The print 70a is intended, in particular, for shaping the material handle body 16a. The print 70a is applied to the first sublayer 68a, in particular, in a pretreatment. Furthermore, layer 18a has a second sublayer 68a'. The second sublayer 68a' is arranged on an inner surface of the first sublayer 68a. The second sublayer 68a' is formed by a sealing wax.The second sublayer 68a' is applied to the first sublayer 68a in a pretreatment. The sealing lacquer serves to bond the layer 18a during rolling. Furthermore, the layer 18a has a third sublayer 68a". The third sublayer 68a" is located on the outer surface of the first sublayer 68a. The third sublayer 68a" is formed by a protective lacquer. The third sublayer 68a" is applied to the first sublayer 68a in a pretreatment. The protective lacquer serves to protect the layer 18a from moisture penetration.

[0129] An arrow 78a in the Figure 1D defines, for example, a direction from an inside of layer 18a to an outside of layer 18a.

[0130] In the Figures 5 , 7 , 9 , 11 , 12 , 14 , 15 and 17Further embodiments of the invention are shown. The following descriptions are essentially limited to the differences between the embodiments, with regard to identical components, features and functions, reference is made to the description of the other embodiments, in particular the Figures 1A to 1C , can be referred to. To distinguish the embodiments, the letter a in the reference numerals of the embodiment according to the invention is used. Figures 1A to 1C by the letters b to t in the reference numeral of the exemplary embodiments of the Figures 2A to 20 replaced. With regard to identically designated components, especially those with the same reference numerals, reference can generally also be made to the drawings and / or the description of the other embodiments, in particular the Figures 1A to 1C , will be referred.

[0131] The Figure 2AA first layer 18b of several handle units 14b of a body care product 10b designed as a flosser is shown during manufacturing. This embodiment is not part of the claimed invention. In the Figures 2A to 2D In particular, several identical personal care products 10b are shown, which are manufactured simultaneously. However, the following discussion focuses primarily on one of the personal care products 10b, although the description is generally applicable to the other personal care products 10b as well.

[0132] The personal care product 10b has an application unit 12b. Furthermore, the personal care product 10b has at least one handle unit 14b connected to the application unit 12b.

[0133] The application unit 12b is located on the top of the personal care product 10b. The application unit 12b forms the uppermost point of the personal care product 10b. The application unit 12b has a cleaning element 24b, which is formed by dental floss. The application unit 12b consists in particular of the cleaning element 24b.

[0134] The grip unit 14b is designed for gripping by the operator. The grip unit 14b further comprises a material grip body 16b. The material grip body 16b forms a material volume of the grip unit 14b. The material grip body 16b has a curved, flat base shape, which divides into two arms 36b, 36b' towards the application unit 12b. The arms 36b, 36b' are designed to hold the dental floss on both sides. The material grip body 16b of the grip unit 14b consists at least partially, and in particular at least predominantly, of a paper material. The material grip body 16b consists entirely of a paper material. The material grip body 16b of the grip unit 14b comprises at least two layers 18b, 20b of a paper material, which are bonded together in a layered fashion. The material handle body 16b of the handle unit 14b has, by way of example, exactly two layers 18b, 20b made of a paper material.Preferably, 2 to 6, and preferably 2 to 4, layers 18b, 20b are provided. Preferably, the at least two layers 18b, 20b are arranged one above the other perpendicular to a principal plane of extension of the layers 18b, 20b and are joined together. The layers 18b, 20b are substantially identical and, in particular, form opposing outer surfaces of the personal care product 10b. The layers 18b, 20b are joined together, for example, by gluing and / or pressing and / or welding and / or laminating. The layers 18b, 20b are joined together, in particular, during the manufacture of the personal care product 10b.

[0135] The application unit 12b is arranged between the at least two layers 18b, 20b of the material handle body 16b on the handle unit 14b. The application unit 12b is arranged and fixed in the area of ​​the two arms 36b, 36b' between the two layers 18b, 20b of the material handle body 16b. The cleaning element 24b of the application unit 12b is stretched between the arms 36b, 36b'.

[0136] In particular, a method for manufacturing the personal care product 10b is disclosed. In this method, the material handle body 16b of the handle unit 14b is layered from at least two interconnected layers 18b, 20b of a paper material. In one manufacturing process, sheets of paper material forming the layers 18b, 20b are pre-cut. Pre-cutting takes place at least in the area of ​​the arrangement of the application unit 12b. In particular, pre-cutting takes place in the areas of the material handle body 16b that can no longer be cut after the application unit 12b is mounted. Subsequently, the pre-cut sheet forming the first layer 18b is prepared, and the cleaning element 24b is inserted (see Figure 1). Figures 2A and 2BThe sheet is intended as an example for the simultaneous production of several personal care products 10b. Subsequently, another pre-cut sheet, which forms the second layer 20b, is placed on top and the layers 18b and 20b are joined, for example by laminating, welding and / or gluing (see Figure 2C ). Subsequently, the personal care product 10b, in particular its outer geometry, can be fully die-cut and excess dental floss thread can be removed from the application unit 12b (see 2D FigureIt would also be conceivable to omit this step and directly punch the correct shape instead of pre-punching, so that the dental floss thread of the application unit 12b does not protrude beyond the final outer geometry. The application unit 12b is glued and / or laminated into at least one connection section 26b between the at least two layers 18b, 20b in the material handle body 16b. The cleaning element 24b of the application unit 12b can be anchored in various ways that would appear sensible to a person skilled in the art. Anchoring can be achieved, for example, by attaching the cleaning element 24b of the application unit 12b using adhesive. Alternatively or additionally, anchoring can be achieved by welding. The cleaning element 24b of the application unit 12b can be attached between the layers 18b, 20b by welding. A single finished personal care product 10b is in the 2D Figure shown.

[0137] The Figure 3A Figure 1 shows a personal care product 10c designed as a flosser in an unfolded state during manufacturing. This embodiment is not part of the claimed invention. The personal care product 10c has an application unit 12c. Furthermore, the personal care product 10c has at least one handle unit 14c connected to the application unit 12c. The application unit 12c is arranged on the top side of the personal care product 10c. The application unit 12c forms the uppermost point of the personal care product 10c. The application unit 12c has a cleaning element 24c, which is formed from dental floss. The application unit 12c consists in particular of the cleaning element 24c.

[0138] The grip unit 14c is designed for gripping by the operator. The grip unit 14c further comprises a material grip body 16c. The material grip body 16c forms a material volume of the grip unit 14c. In its final state, the material grip body 16c has a flat base shape, which extends towards the application unit 12c into two arms 36c, 36c'. The arms 36c, 36c' are designed to hold the dental floss on both sides. The material grip body 16c of the grip unit 14c consists at least partially, and in particular at least predominantly, of a paper material. The material grip body 16c consists entirely of a paper material. The material grip body 16c of the grip unit 14c has at least one layer 18c of a paper material, which is at least partially folded. The material handle body 16c of the handle unit 14c has, by way of example, exactly one layer 18c made of a paper material.Layer 18c comprises a folding axis 38c. Layer 18c has a folding edge 40c along the folding axis 38c. In its operational state, layer 18c is folded around the folding axis 38c at the folding edge 40c. Layer 18c is preferably perforated and / or embossed at the folding edge 40c to enable defined folding. Layer 18c is divided into two sides, in particular sublayers 42c, 42c', by the folding edge 40c. A second sublayer 42c' of the sublayers 42c, 42c' is folded onto a first sublayer 42c of the sublayers 42c, 42c' to create multiple layers. For this purpose, the material handle body 16c has the folding edge 40c, which acts as a hinge, on the upper side of the arms 36c, 36c'. At the fold line 40c, layer 18c can be folded by 180°. The fold axis 38c of layer 18c runs perpendicular to the main extension direction 34c of the body care product 10c.The material handle body 16c can be die-cut from sheets of paper or from a roll. Furthermore, the sublayers 42c and 42c' of the material handle body 16c are joined by sealing or gluing. The layer 18c of the material handle body 16c is cut or die-cut.

[0139] The application unit 12c is anchored to tension tabs 44c, 44c' of the material handle body 16c. The tension tabs 44c, 44c' are integrally connected to the first sublayer 42c of layer 18c. The tension tabs 44c, 44c' project inwards from the arms 36c, 36c' and are designed to be bent over. The cleaning element 24c of the application unit 12c is guided around the tension tabs 44c, 44c'. This prevents tearing out. Furthermore, the cleaning element 24c of the application unit 12c can also be fixed elsewhere, for example, by means of a dot of adhesive. Alternatively, the cleaning element 24c of the application unit 12c can also be shaped as a ring or loop, i.e., in particular as a closed ring without an end, so that further fixation to the tension tabs 44c, 44c' is unnecessary. The ring made from the thread can be produced directly as a ring or by knotting.The paper material of the handle body 16c is sealed during manufacturing, in particular, whereby the tension tabs 44c, 44c' are also sealed, thereby fixing the cleaning element 24c.

[0140] In particular, a method for manufacturing the personal care product 10c is disclosed. In the method, the material handle body 16c of the handle unit 14c is layered from at least two interconnected layers 18c, 20c of a paper material. In one manufacturing process, in particular, layer 18c is die-cut and the application unit 12c is provided (see Figure 3A ). Subsequently, the tension tabs 44c, 44c' are bent over and the cleaning element 24c of the application unit 12c is guided around the tension tabs 44c, 44c' (see Figure 3BFurthermore, the cleaning element 24c of the application unit 12c can subsequently be fixed elsewhere, for example by means of a dot of adhesive. Excess dental floss can then be removed from the application unit 12c. Alternatively, the cleaning element 24c of the application unit 12c can also be shaped as a ring or loop, i.e., in particular as a closed ring without an end, so that further fixation to the tension tabs 44c, 44c' is unnecessary. Subsequently, the second sublayer 42c' of the sublayers 42c, 42c' is folded onto the first sublayer 42c of the sublayers 42c, 42c' and sealed, thereby sealing in the tension tabs 44c, 44c'. A finished personal care product 10c is in the Figure 3C shown. Figure 4A A first layer (18d) shows several handle units (14d), each one as

[0141] Flosser trained in body care product 10d during a manufacturing process. This embodiment is not part of the claimed invention. In the Figures 4A to 4D In particular, several identical personal care products (10d) are shown, which are manufactured simultaneously. However, the following discussion focuses primarily on one of the personal care products (10d), although the description is generally applicable to the other personal care products (10d) as well.

[0142] The personal care product 10d has an application unit 12d. Furthermore, the personal care product 10d has at least one handle unit 14d connected to the application unit 12d.

[0143] The application unit 12d is located on the top surface of the personal care product 10d. The application unit 12d forms the uppermost point of the personal care product 10d. The application unit 12d consists at least partially, and in particular at least predominantly, of a paper material. The application unit 12d includes a cleaning element 24d comprising a paper material. The cleaning element 24d is formed from interdental cleaning paper. The application unit 12d consists of the cleaning element 24d.

[0144] The grip unit 14d is designed for gripping by the operator. The grip unit 14d further comprises a material grip body 16d. The material grip body 16d forms a material volume of the grip unit 14d. The material grip body 16d has a curved, flat base shape, which extends towards the application unit 12d into two arms 36d, 36d'. The arms 36d, 36d' are designed to hold the cleaning element 24d on both sides. The material grip body 16d of the grip unit 14d consists at least partially, and in particular at least predominantly, of a paper material. The material grip body 16d consists entirely of a paper material. The material grip body 16d of the grip unit 14d comprises at least two layers 18d, 20d of a paper material, which are bonded together in a layered fashion. The material handle body 16d of the handle unit 14d has, by way of example, exactly two layers 18d, 20d made of a paper material.Preferably, 2 to 6, preferably 2 to 4, layers 18d, 20d are provided. Preferably, the at least two layers 18d, 20d are arranged one above the other perpendicular to a principal plane of extension of the layers 18d, 20d and joined together. The layers 18d, 20d are substantially identical and form, in particular, opposing outer surfaces of the personal care product 10d. The layers 18d, 20d are joined together, for example, by gluing and / or pressing and / or welding and / or laminating. The layers 18d, 20d are joined together, in particular, during the manufacture of the personal care product 10d.

[0145] The application unit 12d is arranged between at least two layers 18d, 20d of the material handle body 16d on the handle unit 14d. The application unit 12d is arranged and fixed in the region of the two arms 36d, 36d' between the two layers 18d, 20d of the material handle body 16d. The application unit 12d spans between the arms 36d, 36d'.

[0146] In particular, a method for manufacturing the personal care product 10d is disclosed. In this method, the material handle body 16d of the handle unit 14d is layered from at least two interconnected layers 18d, 20d of a paper material. In one manufacturing process, sheets of paper material forming the layers 18d, 20d are pre-cut. Pre-cutting is carried out at least in the area of ​​the arrangement of the application unit 12d. In particular, pre-cutting is carried out in the areas of the material handle body 16d that can no longer be cut after the application unit 12d is mounted. Subsequently, the pre-cut sheet forming the first layer 18d is prepared, and the cleaning element 24d is inserted (see Figures 4A and 4BThe sheet is intended as an example for the simultaneous production of several 10d body care products. Subsequently, another pre-cut sheet, forming the second 20d layer, is placed on top, and the 18d and 20d layers are joined, for example, by laminating, welding, and / or gluing (see Figure 4C ). Subsequently, the personal care product 10d, in particular its outer geometry, can be fully die-cut and excess cleaning element 24d of the application unit 12d can be removed (see 4D FigureIt would also be conceivable to omit a corresponding step and, instead of pre-punching, to directly punch out the correct shape, so that the cleaning element 24d of the application unit 12d does not protrude beyond the final outer geometry. The application unit 12d is glued and / or laminated into the material handle body 16d in at least one connection section 26d between the at least two layers 18d, 20d. The cleaning element 24d of the application unit 12d can be anchored in various ways that would appear sensible to a person skilled in the art. Anchoring can be achieved, for example, by attaching the cleaning element 24d of the application unit 12d using adhesive. Alternatively or additionally, anchoring can be achieved by welding. The dental floss thread of the application unit 12d can be attached between the layers 18d, 20d by welding. A single finished personal care product 10d is in the 4D Figure shown.

[0147] The Figure 5A Figure 1 shows a schematic representation of an application unit 12e of a personal care product 10e. In this case, the personal care product 10e is designed as an interdental brush. In the Figures 5A to 5C and 5E In particular, several identical personal care products 10e are shown, which are manufactured simultaneously. However, the following discussion focuses primarily on one of the personal care products 10e, although the description is generally applicable to the other personal care products 10e as well.

[0148] The personal care product 10e has the application unit 12e. Furthermore, the personal care product 10e has at least one handle unit 14e connected to the application unit 12e.

[0149] The application unit 12e is located on the top of the personal care product 10e. The application unit 12e forms the uppermost point of the personal care product 10e.

[0150] The grip unit 14e is designed for gripping by the operator. The grip unit 14e further comprises a material grip body 16e. The material grip body 16e forms a material volume of the grip unit 14e. The material grip body 16e has a flat, elongated basic shape. The material grip body 16e of the grip unit 14e consists at least partially, and in particular at least predominantly, of a paper material. The material grip body 16e consists entirely of a paper material. The material grip body 16e of the grip unit 14e comprises at least two layers 18e, 20e of a paper material, which are bonded together in a layered manner. By way of example, the material grip body 16e of the grip unit 14e comprises exactly two layers 18e, 20e of a paper material. Preferably, 2 to 6, and more preferably 2 to 4, layers 18e, 20e are provided.Preferably, the at least two layers 18e, 20e are arranged one above the other perpendicular to a principal plane of extension of the layers 18e, 20e and are joined together. The layers 18e, 20e are essentially identical and form, in particular, opposite outer surfaces of the personal care product 10e. The layers 18e, 20e are joined together, for example, by gluing and / or pressing and / or welding and / or laminating. The layers 18e, 20e are joined together, in particular, during the manufacture of the personal care product 10e.

[0151] Furthermore, the application unit 12e comprises a cleaning element carrier 22e and several cleaning elements 24e connected to the cleaning element carrier 22e, in particular twisted into it. The cleaning element carrier 22e is, for example, formed by a wire, wherein the cleaning elements 24 are formed by bristles twisted into the wire.

[0152] The cleaning element carrier 22e is connected to the handle unit 14e by a connecting section 26e facing away from the cleaning elements 24e and to the material handle body 16e. The connecting section 26e is formed, in particular, by a wire end facing away from the cleaning elements 24e. The connecting section 26e of the cleaning element carrier 22e of the application unit 12e projects, particularly in a manufactured state of the personal care product 10e, into the material handle body 16e and is enclosed by it. The application unit 12e is directly connected to the material handle body 16e via the connecting section 26e. The connecting section 26e is arranged between the at least two layers 18e, 20e of the material handle body 16e on the handle unit 14e.Furthermore, the cleaning element carrier 22e of the application unit 12e is formed in a partially positive-locking connection with the handle unit 14e in the connection section 26e, with the bend not visibly visible.

[0153] In particular, a method for manufacturing the personal care product 10e is disclosed. In this method, the material handle body 16e of the handle unit 14e is layered from at least two interconnected layers 18e, 20e of a paper material. A corresponding manufacturing process could, in one variant, proceed such that in a first step the application unit 12e in the form of an interdental brush is manufactured by twisting (see Fig. 5A ). Subsequently, in particular, a sheet forming the first layer 18e is prepared and the application unit 12e with the connecting section 26e is inserted (see Figure 5BThe sheet is intended as an example for the simultaneous production of several personal care products 10e. Subsequently, another sheet, forming the second layer 20e, is placed on top, and the layers 18e and 20e are joined, for example, by laminating, welding, and / or gluing (see Figure 5C ). Subsequently, the personal care product 10e, in particular its external geometry, can be die-cut (see 5D Figure A single finished body care product (10e) is included in the 5D Figure shown.

[0154] Optionally, during the manufacturing of the 10e body care products, they can be grouped and separated upon use. The 10e body care products can be partially connected by the paper material, with a discreet perforation at which they can be separated. This allows for simpler processing, as the products are manufactured in groups and separated only upon use (see Figure 5e ).

[0155] The Figure 6AFigure 1 shows a layer 18f of a handle unit 14f of a personal care product 10f designed as a flosser during manufacturing. This embodiment is not part of the claimed invention. The personal care product 10f has an application unit 12f. Furthermore, the personal care product 10f has at least one handle unit 14f connected to the application unit 12f. The application unit 12f is arranged on the top side of the personal care product 10f. The application unit 12f forms the uppermost point of the personal care product 10f. The application unit 12f has a cleaning element 24f, which is formed by dental floss. The application unit 12f consists in particular of the cleaning element 24f.

[0156] The grip unit 14f is designed for gripping by the operator. The grip unit 14f further comprises a material grip body 16f. The material grip body 16f forms a material volume of the grip unit 14f. In its final state, the material grip body 16f has a flat base shape, which extends towards the application unit 12f into two arms 36f, 36f'. The arms 36f, 36f' are designed to hold the cleaning element 24f on both sides. The material grip body 16f of the grip unit 14f consists at least partially, and in particular at least predominantly, of a paper material. The material grip body 16f consists entirely of a paper material. The material grip body 16f of the grip unit 14f has at least one layer 18f of a paper material. The layer 18f of the material grip body 16f is cut or punched.

[0157] The application unit 12f is sewn to the material handle body 16f. The cleaning element 24f is sewn to the material handle body 16f at both ends of the arms 36f, 36f'. The personal care product 10f has further threads 46f by means of which the cleaning element 24f is sewn to the material handle body 16f. It would also be conceivable that the dental floss thread is sewn onto the first layer 18f, with the dental floss thread being used as the sewing medium. The layer 18f has a material thickness of 0.5 mm to 2 mm, preferably 0.5 mm to 1.5 mm, with a density of 180 g / m² to 500 g / m², preferably 240 g / m² to 400 g / m², particularly so that a connection by sewing is feasible.

[0158] In particular, a method for manufacturing the personal care product 10f is disclosed. In this method, the application unit 12f is sewn onto the material handle body 16f. In one manufacturing process, in particular, the layer 18f is stamped (see Figure 6A ). In particular, at least the areas of the material handle body 16f in which the application unit 12f is arranged are punched out. Subsequently, the layer 18f is prepared and the cleaning element 24f is provided and sewn on using the threads 46f, 46f' (see Figure 6B A finished body care product (10f) is in the Figure 6B shown.

[0159] The Figure 7A Figure 1 shows a schematic perspective view of the front of a 10g personal care product. In this case, the 10g personal care product is designed as a toothbrush.

[0160] The 10g personal care product has at least one 12g application unit. Furthermore, the 10g personal care product has at least one 14g handle unit.

[0161] The at least one application unit (12g) has a head section (48g). The head section (48g) forms a brush head for the personal care product (10g). The head section (48g) forms a cleaning element carrier (22g) for the personal care product (10g). In the present case, the head section (48g) is designed as a toothbrush head. The head section (48g) has, in particular, a base body designed as a bristle carrier. The base body of the head section (48g) is made entirely of a hard component. However, it would also be conceivable that the base body of the head section (48g) is made of a hard component and a soft component. The base body of the head section (48g) forms a bristle carrier. The personal care product (10g) also has a plurality of bristle holes in the head section (48g) in the form of recesses, each of which receives a bristle bundle. The bristle bundles form cleaning elements (24g) of the personal care product (10g).

[0162] Alternatively, the 10g body care product could contain a bristle plate absorbed from the head area (48g), which comprises a plurality of bristle bundles. The bristle plate is exemplified by an AFT plate.

[0163] Any suitable bristles can be used. Furthermore, the application unit (12g) in this case includes a neck section (50g), which connects the head section (48g) to the handle unit (14g). The neck section (50g) forms a neck.

[0164] Furthermore, the 10g personal care product has a 52g base body. The 52g base body consists at least partially of a hard component. The 52g base body consists entirely of a hard component. The 52g base body is formed in one piece. The 52g base body forms the 12g application unit. The 52g base body forms the 12g application unit completely. The 52g base body also partially forms the 14g handle unit. The 52g base body forms a core of the 14g handle unit. The 52g base body has an at least approximately cylindrical shape in one area of ​​the 14g handle unit. The 52g base body extends along a longitudinal axis of 30g along the entire 10g personal care product. The 52g base body has a rounded end at one rear end of the 10g personal care product. The 52g base body may be made of paper material.

[0165] The grip unit 14g is designed for gripping by the operator. The grip unit 14g has a cylindrical base shape. The grip unit 14g also has a material grip body 16g. The material grip body 16g forms a material volume of the grip unit 14g. The material grip body 16g has an ellipsoidal shape. The material grip body 16g of the grip unit 14g consists at least partially, and in particular at least predominantly, of a paper material. The material grip body 16g consists entirely of a paper material. The material handle body 16g of the handle unit 14g has several sub-elements 54g, 54g', 56g, 56g', 56g", 56g‴, which are designed to be assembled. For this purpose, a paper material is cut into the sub-elements 54g, 54g', 56g, 56g', 56g", 56g‴ and then the sub-elements 54g, 54g', 56g, 56g', 56g", 56g‴ are assembled.

[0166] The base body (52g) and the handle body (16g) form a positive fit. The sub-elements 54g, 54g', 56g, 56g', 56g", 56g‴ of the material handle body 16g are attached to the base body 52g. The base body 52g has interlocking recesses 58g, 58g' for this purpose, which are designed to form a positive connection with at least two sub-elements 54g, 54g' of the handle body 16g. The first two sub-elements 54g, 54g' are formed from discs made of a paper material, each of which has a receiving groove for sliding onto the interlocking recesses 58g, 58g'. Furthermore, the first two sub-elements 54g, 54g' each have interlocking recesses around one outer surface for a positive connection with the other sub-elements 56g, 56g', 56g", 56g‴ of the handle body 16g. The further sub-elements 56g, 56g', 56g", 56g‴ are each formed by arc-shaped elements which extend along the longitudinal axis 30g along the base body 52g.This allows, in particular, the provision of an advantageously three-dimensional handle unit (14g), while minimizing material usage. The personal care product (10g), or rather its body, can consist of, in particular, 2 to 25, preferably 4 to 12, individual parts.

[0167] The 10g body care product can be assembled either during manufacturing or by the user. Assembly by the user allows for a particularly advantageous reduction in the packaging size of the 10g body care product (see Figure 7B ).

[0168] The 10g personal care product is manufactured using a single process. In the first step of this process, the 52g base unit with the 12g application unit is injection-molded and prepared. Subsequently, the individual components 54g, 54g', 56g, 56g', 56g", 56g‴ are cut and, optionally, attached to the 52g base unit and assembled. Safety devices may be provided for the individual components 54g, 54g', 56g, 56g', 56g", 56g‴.
