Definitions

  • the invention relates to a method for producing a toothbrush and a toothbrush according to the preamble of claims 1 and 14, respectively.
  • Disposable toothbrushes are already known which already contain toothpaste in various ways.
  • US 5,346,324 and US 5,909,977 there is low viscosity toothpaste in a reservoir in the handle area and is pressed by a piston into the head area, where it emerges through openings in the area of the bristles.
  • Disadvantages of this are the difficult metering of the toothpaste, the need to use very low viscosity toothpaste, the unwieldy handle, the frequent drying and thus clogging of the fluid channel, as well as the difficult or impossible refilling of the reservoir.
  • Toothbrushes are also known in which a predetermined amount of toothpaste is located in a hollow area in the head area and is pressed out by manual deformation of the head area before cleaning.
  • a slit-like, initially closed opening is broken open by deforming the head area so that the toothpaste can escape. Multiple use by refilling or an exact dosage is not possible.
  • the delivery of toothpaste is also associated with a relatively large amount of effort. Show similar examples of toothpaste dispensing by manual squeezing FR 2 583 625 or US 5,865,195 , In the US 5,490,530 can they Exit openings can be closed again by a slide.
  • the toothpaste is pressed out by pressing a button which is arranged on the underside of the head part and which reduces the volume of the toothpaste reservoir. Precise dosing of the toothpaste is also difficult here. Refilling the reservoir is impossible.
  • the toothpaste is in a sealed capsule that is inserted into the brush head. After removing the seal, the toothpaste is released by manual squeezing. In principle, refilling is possible here, but the exact dosage is still difficult.
  • a disposable toothbrush contains an encapsulated portion of liquid tooth cleaning agent in the bristle area.
  • the capsule is broken open by contact with the teeth.
  • the cleaning agent can also escape if it is handled improperly.
  • the US 2,216,333 a toothbrush with a solid layer of a bactericidal material, which in the area of the bristle base firmly in the head part is anchored, the bristles extending through the layer.
  • the invention is therefore based on the object of providing methods for producing a toothbrush and a toothbrush with an active substance which is suitable for multiple use and / or topping up the active substance and which enables simple handling and simple metering of the active substance. Furthermore, a method for producing such a brush is to be specified.
  • an active substance element in the hollow region, which preferably consists of a carrier material and the active substance incorporated therein.
  • the carrier material releases the active substance in a controlled manner when it comes into contact with water.
  • the carrier material is preferably solid, but can also be a paste with high viscosity. It is preferably largely dimensionally stable without contact with water.
  • the cavity is adapted to the shape of the active substance element with a defined outer shape.
  • the volume of the hollow area is greater than the volume of the active substance element, in particular 1-2 times, at most 4 times larger.
  • the Active substance can also protrude from the head in order to form a sufficient target area for the release of active substances. This ensures that the active substance element is well washed around by water during use.
  • the active substance is released passively by rinsing the active substance element with water, manual influencing of the brush is not necessary.
  • the brush would therefore already give off significant active substances if it were immersed in water at temperatures of 15 ° Celsius or higher.
  • the cleaning movement can additionally support the migration of the active substance through the improved liquid circulation, but the aim is that the brush releases active substances in connection with water without mechanical effects.
  • the dosage can be adjusted and specified by a suitable choice of the solubility or decomposability of the active substance element or its ability to release the active substance and the size of the outlet openings, and is therefore also not dependent on the skill of the user.
  • the brush at least in the area of the hollow area, is so flexible that the hollow area is deformed when used as intended, ie when cleaning, in such a way that water is drawn into the hollow area and pushed out again.
  • a pumping / suction effect with respect to the solvent water which is made possible by the flexibility of the hollow area, is used. This can prevent water from entering the cavity and the rinsing out of the active substance can be increased without the user having to manipulate the brush beforehand.
  • the hollow area is preferably adapted to the shape of the active substance element in such a way that it is at least partially spaced from the inner wall and is thus washed around by water when in use.
  • the hollow area is advantageously at least partially enclosed by thin-walled boundary elements with a wall thickness of less than 3 mm, preferably less than 1.5 mm, made of rubber-elastic soft material in order to generate said pumping action even with the slightest contact.
  • the entire brush head can also have flexible, movable partial areas, e.g. have a flexible brush head front part.
  • the volume of the hollow area is also influenced by the flexible deflection of this partial area and the pumping / suction effect described above arises again.
  • the flexibility of the brush head is preferably formed at the point at which the hollow area occupies the largest part of the cross section of the brush head. This has the advantage that only a small proportion of the head cross section has to be designed flexibly. This can be done by means of targeted material weakening, e.g. Film hinge, side tunnel etc., done in the hard component or by combining the hard and soft components. It is also possible to form the flexible zone entirely from soft material.
  • the active substance element is preferably a solid or a highly viscous, dimensionally stable paste, but can also be formed by an encapsulated liquid, pasty or granular substance with a water-soluble coating.
  • solubility or The decomposability of the active substance element or its coating succeeds in a well-defined dosage up to a uniform release of active substance during a cleaning process.
  • a solid or a highly viscous paste multiple use of the same active substance element is possible if it is dimensioned or its solubility or decomposability is selected so that it lasts for several typical cleaning processes.
  • the active substances are released before, during or after the cleaning process. In this case, there is no risk of openings drying out or becoming blocked, since any residues can be easily rinsed off after use.
  • the active substance element comprises a largely dimensionally stable carrier from which the active substance is washed out, but which retains its original shape. It preferably contains an indicator by which it changes color or fades with the period of use or the number of uses.
  • the active substance element can be refilled through a reclosable inlet opening. This means that the step from a simply designed disposable brush to a high-quality cleaning product can be completed.
  • the brush consists of a head part with a cleaning structure, usually bristles, a neck part and a handle part. All sub-elements can consist of at least one hard and one or more soft components.
  • hard components e.g. Polystyrene (PS), styrene acrylonitrile (SAN), polyester (PET), polyethylene (PE), polymethyl methacrylate (PMMA), acrylic butadiene styrene (ABS) etc., preferably polypropylene (PP).
  • a rubber-elastic material such as polyurethane (PUR) or polyethylene (PE), preferably a thermoplastic elastomer (TPE or TPU), is used as the soft component.
  • the bristle field is preferably at least partially coated with conventional bristles e.g. Made of polyamide (PA) or polyester (PBT) and optionally with rubber-elastic cleaning or massage elements.
  • the conventional bristles have, for example, a cylindrical geometry with a diameter of less than 0.25 mm, preferably between 0.1 mm and 0.2 mm, and are combined into bundles.
  • the rubber-elastic massage or cleaning elements usually have larger diameters with smallest dimensions in the cross section of 0.5 to 5 mm, preferably 0.5 to 2 mm.
  • the hollow area offers at least space for an active substance element, preferably the hollow area offers additional space so that the active substance element can be washed around with water and the active substance can thereby develop its effect by partial or complete dissolution.
  • the volume of the hollow area is a maximum of four times, particularly preferably one or two times larger than the size (the volume in the original size) of the active substance element.
  • the hollow area has a volume of 5 to 1500 mm 3, preferably 100 to 500 mm 3 .
  • the active substance element can be clamped laterally or vertically in the hollow area.
  • protrusions or other geometric elements in the soft or / and hard component are preferably used in the hollow area. This ensures that the active substance element is not bounced back and forth within the hollow area during the cleaning process can and possibly break apart prematurely.
  • the active substance element can also protrude outwards through recesses in the boundary of the cavity and look out of the brush head from the side or on the bristle-bearing side.
  • the hollow area is preferably generally designed such that the active substance element is stably positioned in the hollow area despite continuous degradation.
  • the hollow area is preferably provided with a flexible element, preferably made of soft material, which exerts a kind of spring action on the active substance element, for example by an outer wall of the hollow area is arched outwards by inserting the active substance element.
  • the active substance element in its original size is fixed in the hollow area with a certain preload.
  • the inner shape of the hollow area essentially follows the geometric shape of the active substance element, preferably with a predefined distance.
  • the hollow area can be designed as a slot into which a plate-shaped or film-shaped active substance element can be inserted.
  • the active substance element can be introduced in a rod-shaped or cylindrical geometry into a correspondingly shaped hollow area.
  • the hollow area is preferably within the bristle field, provided conventional bristles are present are.
  • cleaning elements are preferably formed from a soft component, which require less head volume or anchoring depth for anchoring than conventional bristles.
  • conventional bristles require the hard component for secure anchoring. Since the hollow area on the bristle-bearing side of the brush head is preferably delimited by a membrane made of soft material, it is technically very difficult to anchor conventional bristles in this area.
  • the hollow area is delimited by a wall made of hard and / or soft components, but preferably at least in some areas by soft components, since the flexibility mentioned above can be achieved in a simple manner.
  • the hollow area has at least one outlet opening for water to enter the active substance dissolved in water and for rinsing out the hollow area after use under the tap.
  • at least one insertion opening for the introduction of the active substance element by the user is additionally present. When opened, the insertion opening is larger than an outlet opening.
  • the insertion opening is preferably on the back of the brush head and the outlet opening on the front of the brush head.
  • Alternative design variants show the insertion opening on the brush head side.
  • the outlet openings can alternatively / additionally be created on the side and / or rear of the brush head.
  • the insertion opening is preferably reclosable. However, it can also serve as an outlet opening and does not have to seal the hollow area completely.
  • the insertion opening can be formed by means of a removable cover or closure integrated in the head, for example by means of a film hinge molded directly onto the head.
  • a membrane made of soft material with a corresponding opening, for example with one or more crossed slits, which corresponds to the size of the active substance element, is particularly preferably used as a reclosable element.
  • the membrane can simultaneously represent a flexible wall of the hollow area and / or serve as a support for cleaning / massage elements.
  • slits other geometric elements can be provided which allow the active substance element to be inserted and prevent it from escaping, for example an expandable hole in the membrane which is smaller than the active substance element.
  • a membrane In the case of a membrane, it has a thickness of less than 3 mm, preferably a thickness of 0.7-1.5 mm. Preferably 2 to 6 slots are used as the insertion opening. The length of the slots for toothbrushes is 3 - 15 mm, preferably around 6 - 10 mm.
  • the insertion opening can have a safety device which prevents the active substance element from falling out during use or at least makes it difficult.
  • the membrane is shaped with slits or a funnel in such a way that the active substance is introduced with little pressure (e.g. 10 to 300 g), but it falls out using a e.g. funnel-shaped geometry in the opening area requires more pressure. Additional locking or securing elements are less preferred, but also possible.
  • the insertion opening can still be closed the first time it is used (tamper-proof or seal).
  • the tamper-proof can be broken by the user, e.g. by cutting through thin remaining connections within the prefabricated slots.
  • the outlet openings allow a continuous but limited outlet of the active substance dissolved in water.
  • the number of openings and their size (total surface of the outlet opening) and the water solubility of the active substance element or of the carrier material determine the actual outlet of the active substance dissolved or dispersed in water. Since the water solubility of the active substance is more of a resultant variable, the outlet openings (number and size) become the water solubility of the active substance adjusted to determine the range of the active substance during use.
  • the dissolution of the active substance element can thus also serve as a time indicator for the (total) cleaning time that has taken place to date.
  • a single outlet opening preferably does not fall below a minimum area of 0.05 mm 2 . Because smaller openings can easily become dirty and thus impair the fluid exchange.
  • the individual outlet openings on a brush head can have different sizes (areas) in order to weight the outlet quantity and outlet location.
  • Individual groups of outlet openings are preferably provided at designated locations on the brush head.
  • the amount and location of the active substances can thus be controlled at various points in the bristle field.
  • Preferably one to five groups (clusters) of outlet openings are formed.
  • These groups of outlet openings can also be positioned asymmetrically with respect to the longitudinal axis on the brush head.
  • the different groups of outlet openings are preferably made in one operation from the same material.
  • the outlet openings are embedded in the rubber-elastic material, this is served for all groups from a spraying point, ie these groups are connected to one another on the material side.
  • the outlet openings can be designed in such a way that they have geometric elements which increase the surface in the vicinity of the outlet opening in order to keep the active substance as close as possible to the area of the brush head.
  • an essentially funnel-shaped geometry or at least opening towards the outside can be used. This also facilitates easy cleaning of the hollow area after use under the tap.
  • Additional cleaning and massage elements in the area of the outlet openings have the same advantage.
  • soft elements can be placed in the area of the outlet openings, which also contribute to better retention of the active substance.
  • the outlet openings can be formed in the hard material and / or in the soft material of the brush head. However, they are preferably integrated into the membrane made of soft material, which is described in more detail above. In this case, it preferably has a thickness of less than 3 mm, preferably 0.7-1.5 mm.

A special flexibility of the brush head 10 and increased pumping / suction effect in the hollow area 22 are achieved by this design.
  • connection made of hard component 30 can also be made within the soft component 32, which allows the two brush head parts 10 ′, 10 ′′ to be produced from hard component 30 in one work step.
  • This connection is preferably made very thin so that the flexibility is not negatively influenced
  • conventional bristles 14 are anchored in the hard component 30, while the soft component 32 is provided with soft-elastic cleaning elements 16.
  • the insertion opening 34 is as in FIG Fig. 1-7 designed as a cross recess.
  • the flexible zone 29 formed from soft material 32 occupies the entire brush tip and is essentially circular in plan. In a concentric arrangement, it carries flexible cleaning elements 16, outlet openings 36 and conventional bristles 14 (or their anchoring areas) from the inside to the outside. In the direction of the neck area 52 there is a conventional bristle field embedded in the hard component 30.
  • the outlet openings 36 are so large that the hollow area 22 behind them can be seen.
  • the part of the brush head formed from the hard component 30 is in one piece. However, it has cutouts in such a way that a flexible zone 29 with three areas (clusters) 44 connected to the rear side 20 is formed by outlet openings 36. These are located at the tip and on the sides of the head region 10 in a flexible wall / membrane 28, preferably made of soft material 32, which is curved outwards.
  • the remaining region of the head part 10 is bristled on the front side 18 with conventional bristles 14; on the back there is again a cross-slot-shaped insertion opening 34 as in Fig. 5-7 ,
  • Fig. 16-21 show examples of different shapes of the flexible zone 29 in a toothbrush in front and rear view ( Fig. 16-19 ) or only in front view ( 20, 21 ). In all examples there is again a cross-slot-shaped insertion opening 34 on the back as in the case of Fig. 5-7 (only partially shown).
  • the flexible zone 29 has three gill-like areas 46 (or Cluster 44) with lamellar cleaning / massage elements 16 and outlet openings 36 arranged between them.
  • the areas 46 are connected to one another on the back by a material bridge made of soft material 32 (see Fig. 17 ).
  • the lamella / fish gills are less pronounced and only two lateral clusters 44 are present.
  • the outlet openings 36 are evenly distributed over the lateral edge of the head region 10 and are surrounded in each case in the manner of nubs by soft material, so that here too the nubs have a massage effect when cleaning.
  • the rear side 20 consists largely of hard material 30, which is perforated like a net and exposes the view of the hollow area 22 within the brush head 10.
  • the hollow area 22 extends essentially over the entire surface of the head part 10. The sufficient flexibility of the wall of the hollow area 22 is achieved by a correspondingly thin material thickness and by the openings or outlet openings 36.
  • a part of the hollow area 22 is covered on the back by a membrane 26 made of soft material 32, in which there are slots arranged in a star shape and serving as an insertion opening 34.
  • the brush head 10 consists of two parts (tip 10 ′ and neck-side region 10 ′′) made of a hard component 30 that pass through one another a flexible zone 29 of soft material 32 or a combination of hard and soft material are connected.
  • a hollow region 22 is formed in the flexible zone 29 in the form of a tubular recess with an elliptical cross section.
  • the hollow area 22 is delimited towards the front 18 by three webs 48 made of soft material 32. Between the webs 48 there are two outlet openings 36 with a total width of approximately half the head width.
  • the underside of the hollow area 22 consists of soft material 32 over its entire surface or a combination of hard and soft material.
  • Soft-elastic cleaning elements 16 are arranged on the webs 48, and conventional bristles 14 are anchored on the hard areas at the tip and in the neck area.
  • An elliptical insertion opening 34 for the active substance element 24 is formed between the webs 48 and the underside 66 of the hollow region 22. This has essentially the shape of a cylinder with an elliptical cross section and rounded edges. The active substance element 24 is clamped between the webs and the underside 66. However, it is laterally spaced from the inner wall of the hollow region 22, so that water is washed around it and in the region of the outlet openings 36.
  • the brush head is particularly flexible.
  • the webs 48 can also consist of the hard component 30 and connect the tip and the neck region in a hinge-like manner; the flexibility is ensured in this case by a correspondingly thin wall thickness of the webs 48.
  • Fig. 25-27 show variations of the example Fig. 24 with also an essentially two-part Head region 10 made of a hard component 30 and a flexible zone 29 made of soft component 32 or a combination of hard and soft components connecting the parts 10 ′, 10 ′′, in which the hollow region 22 for accommodating the active substance element 24 is accommodated 25 and 26 are the hollow area 22 and the active substance element 24 itself cylindrical with a circular cross section.
  • the insertion opening 34 is also circular and can have a smaller diameter than the hollow area 22 itself, so that the active substance element 24 can be at least partially washed around in the hollow area 22.
  • the hollow area 22 is essentially surrounded by soft material 32 in the radial direction of its longitudinal direction, with the exception of the outlet openings 36 in the front-side membrane 28.
  • Fig. 25 are molded onto the membrane 28 by tubular elastic cleaning elements 16, the interior of which communicates with the hollow area 22, so that dissolved active substance is also dispensed via outlet openings 36 'at the upper end of the cleaning elements 16.
  • the active substance release is increased by the capillary effect.
  • no flexible cleaning elements are arranged on the soft component.
  • Fig. 27 shows an analogous example with an elastic zone 29 elongated in the longitudinal direction of the brush head, in which an essentially cuboidal hollow area 22 is formed.
  • This is adapted to a plate or film-shaped active substance element 24.
  • the plate-shaped or foil-shaped hollow area 22 can be attached as a backpack-shaped structure on the back of the brush head.
  • the active substance element 24 has a thickness of 0.01 to 5.0 mm, preferably 0.05 to 1.0 mm.
  • a corresponding sideshift is used to form the tunnel-like cavity for the active substance element in the injection molding tool for injecting the hard and / or soft component.
  • the hollow area 22 on the back 20 of the brush head is covered by a flexible membrane 26 made of soft material 32 and is otherwise formed within the hard component 30.
  • the outlet openings 36 are formed on the membrane 26 within bump-like or funnel-like elevations, which can simultaneously act as cleaning or massage elements 16, in particular for the palate and tongue.
  • the front 18 consisting of the hard component 30 can thus also be conventionally bristled above the hollow area 22.
  • a combination of this embodiment with a previously shown flexible membrane on the front of the brush head is also conceivable. Due to the movement of the knobs during cleaning, water is sucked into the hollow area and expelled again with active ingredient.
  • Fig. 29 shows a toothbrush in which the hollow area 22 is formed by a cage-like thickening in the neck area 52 which is adapted to a spherical or ellipsoidal shape of the active substance element. This has a multiplicity of outlet openings 36 through which the hollow region 22 can be seen.
  • the delimitation of the hollow area can be formed from hard and / or soft components, in the latter case there being a damping zone in the neck area 52. The flexibility of this zone favors the pumping effect around the active substance element discussed earlier.
  • Fig. 30-33 schematically show different manufacturing methods for brushes. Of course, these manufacturing methods can be used for all of the design variants shown.
  • the toothbrush is made from two parts consisting of hard and / or soft component 30 in an injection molding process, on the one hand the bristle-side upper half of the brush head and on the other hand the rear cover 54.
  • the upper half there is a recess for the active substance element 24 formed, which is later closed with the lid 54 to form the hollow region 22.
  • the outlet openings 36 and optionally cleaning elements 16 made of soft component 32 are formed on the upper half.
  • Conventional bristles are anchored to the side of the cleaning elements 16 by conventional plugging or in mold tufting (IMT).
  • Further outlet openings 36 are formed in the hard component 30 on the cover 54.
  • the cover 54 can also contain a membrane made of soft component, in which the outlet openings are formed in nub-like elevations. Cover 54 and the remaining brush head are then detachably connected (including snapping, pushing, latching, etc.) or undetachably (gluing, welding, positive locking, etc.), including a flat active substance element 24.
  • the toothbrush according to the invention is also produced from two parts from a hard and / or soft component in an injection molding process.
  • the half of the brush head on the back of the brush head has a plate-shaped depression which, when assembled, forms a cavity 22 with a carrier plate 56.
  • the Carrier plate is produced including openings which are closed in a further injection molding step with soft component 32 to form a membrane 26 and possibly also flexible cleaning elements 16 made of soft component.
  • the conventional bristles 14 are then anchored in the carrier plate 56.
  • the carrier plate 56 can also be bristled using the anchor free tufting method, which has the advantage that the carrier plate can be made thinner.
  • the carrier plate is then connected to the rest of the toothbrush in a non-detachable manner (gluing, welding, positive locking, etc.), an active substance element 24 designed as a solid or highly viscous, dimensionally stable paste being enclosed in the cavity 22.
  • Fig. 32 shows a combination of the examples 30 and 31 with a brush head consisting of three parts (ring-shaped body, carrier plate 56 and rear cover 54).
  • Fig. 33 shows a further example in which the active substance is inserted or injected into a recess in the hard component 30 during the manufacture of the toothbrush and overmolded with the soft component 32.
  • a cavity 22 is formed with a flexible wall in the form of a thin membrane 26 made of soft component 32. Openings 36 for the entry and exit of water or water-soluble active substance are provided in the membrane 26.
  • the flexibility of the wall of the hollow area 22 results from the selection of a wall material with a certain elasticity, in particular by at least one membrane made of soft material 32, and / or due to the overall elasticity of the brush made of hard and / or soft material. As long as sufficient contact with water or sufficient dissolution of the active substance is guaranteed, it is sufficient if the pumping / suction effect or volume change of the hollow area is only slightly or not at all due to the cleaning pressure.
  • 34 and 35 show a self-explanatory packaging 58 for a toothbrush with active substance, in which, in addition to a recess 60 adapted to the shape of the brush, there is a separable area, each with an active substance element 24. The user therefore immediately recognizes which product it is.
  • the design variants shown above can of course also be used with electric toothbrushes.
  • the mechanical movement or vibration of at least part of the brush head also favors the exchange of liquids in and out of the hollow area. If the brush head is divided into a movable and a non-movable brush head segment, the hollow area is preferably accommodated in the non-movable segment within the variants described above.
  • Fig. 36 shows a household brush also with a head, neck and handle area 10, 52, 62.
  • head area 10 In the head area 10 there is a hollow area 22 which can be reclosed on the side facing away from the cleaning structure 12 by a flap 64 and which can hold an active substance element 24.
  • the outlet openings for the dissolved active substance are located in the flap 64.
  • a solid soap is preferably used Active substance element used for the dishwashing brush. All of the previously shown design variants can be adopted analogously for the dishwashing brush.
  • the specified dimensions are to be adjusted in relation to the dimensions of the dish brush head.
  • a brush with a flexible membrane in the head part, which carries cleaning and / or massage elements has advantages even without an underlying hollow area or without an active substance element introduced into the hollow area, in particular because of the flexible suspension of the cleaning and / or massage elements. All of the examples shown can be modified accordingly, for example by not providing a hollow area or a hollow area that does not communicate with the outside world.
