Definitions

  • the invention relates to a toothbrush according to the preamble of claim 1.
  • Such a toothbrush is known from DE GbM 72 47 425.
  • the manual dosing device is achieved by the interaction between a self-locking knurled nut and a toothed rack, the end of the toothed rack facing the brush head being provided with a pressure plate which is intended to push the dentifrice in front of it.
  • this construction requires extremely high precision between the pressure plate and the inner surface of the hollow handle to prevent that The dentifrice swirled past the pressure plate and dried up in the space between the knurled nut and the pressure plate.
  • a toothbrush is known from DE OS 23 28 251, in which a toothpaste tube can be accommodated within a handle, the toothpaste tube being intended to be expressed by a ball or a roller movable along the handle.
  • a self-locking manual dosing device is not provided.
  • a stopper is guided in a tooth grid within a stem tube.
  • the plug is tapered in the direction of movement. This means that when the plug is pushed forward, the handle is widened so that the toothpaste located in front of the plug is squeezed into the annular space between the handle and the plug. Economical and complete utilization of the entire tube content is not possible with this toothbrush, since the toothpaste squeezed in a ring past the stopper also gets into the already empty space of the stem tube as the stopper is pushed forward.
  • DE 34 34 400 also does not provide a solution to this.
  • the handle is formed directly by the tube.
  • a grid in the sense of blocking against the metering direction is not provided.
  • DE OS 38 32 224 should be mentioned.
  • the dentifrice is poured directly into the handle, so that similar problems arise with regard to the tightness of the piston as with the already mentioned DE GbM 72 47 425.
  • the object of the invention is to improve the generic toothbrush in such a way that these disadvantages are eliminated, with particular emphasis being placed on the toothbrush offering optimum hygienic conditions for storing the dentifrice while being very simple to use.
  • the dentifrice is housed in a hose body and that the handle has a grid path on which the hand-held metering device can only be moved in the metering direction and in such a way that the hose body is emptied, preferably squeezed out.
  • Insulated storage of the dentifrice in the absence of air is thereby achieved, with the additional advantage that the number of utensils required for dental care is limited to ONE.
  • the invention has not only recognized that the handle offers an excellent possibility to accommodate a separate receptacle for the dentifrice.
  • the invention has also recognized that a separate receptacle combined with a squeezing device that can only be moved in the emptying direction offers the required hygienic conditions.
  • the pressure-resistant handle reliably prevents dentifrice from being accidentally expelled.
  • the handle is hollow and that the receptacle is housed within the hollow handle.
  • the receptacle is provided with a connecting line from which the dentifrice can be driven out to the brush head.
  • the connecting line between the receptacle and the brush head should run, preferably concealed, preferably within the material of the handle and brush head.
  • a hose line or a corresponding channel system between the receptacle and the brush head is recommended for this.
  • the receptacle is connected to a hand-held dosing device in order to be able to drive out the dentifrice located in the interior of the receptacle via the connecting line to the brush head if required.
  • the hand dosing device can be implemented in different ways. It is advisable, for example, to design the receptacle to be tube-like and to guide a squeeze roller along the tube-like receptacle with the hand dosing device, with a corresponding quantity depending on the feed path of the hand dosing device of dentifrice is squeezed out of the tube-like receptacle.
  • the receptacle is of straight cylindrical design and has a piston-like bottom in the interior, which can be moved piece by piece in the longitudinal direction of the brush head using the manual dosing device.
  • a piston guide rod should preferably run exclusively within the handle and should not be recognizable from the outside.
  • a respective quantity of dentifrice is displaced from the receiving container and expelled in the direction of the brush head.
  • the receptacle or the connecting line can be provided with a valve that can be pressure-controlled in the opening direction on the brush head.
  • a valve that can be pressure-controlled in the opening direction on the brush head.
  • the handle is hollow, there is the advantage that the toothbrush is given a uniform, attractive appearance, and in particular that the handle becomes particularly stable.
  • the hand dosing device is movable in the longitudinal direction of the handle, this gives the advantage that the hand dosing device can be integrated ergonomically particularly well into the handle.
  • the invention also covers such manual dosing devices in which Within a straight cylindrical tube, a base which is movable in the longitudinal direction of the tube but does not rotate is guided like a piston.
  • the bottom has, for example, a central feed thread, in which a threaded rod is inserted, which is rotated by a rotary drive from the end of the toothbrush handle. As a result of the rotation, the base is driven according to the thread pitch and thus the toothpaste is pressed out.
  • the grid path has the advantage that the progress in the consumption of dentifrices can be correctly recognized from the outside at all times. This feature means that the user is reminded in time to buy a new toothbrush.
  • Another advantage that results from the invention is the versatility. Thanks to the invention, it is easily possible for field workers, field workers, local craftsmen, construction workers, campers, holidaymakers, to name a few, to have a fully functional toothbrush with them at all times.
  • a development of the invention results from the features of claim 2 with the advantage that the volume of the dentifrice remains as low as possible.
  • This development of the invention takes into account in particular the fact that the toothbrush according to the invention can "only" be a disposable item. Therefore, the invention also aims to keep the volume of waste as low as possible. This requirement is met in that the space requirement of the dentifrice is kept as low as possible.
  • dentifrice consistency can be between gel-like and liquid. But dentifrices with a creamy consistency can also be used.
  • the toothbrush according to the invention can be filled, for example, with a children's toothpaste, so that preschool children can also brush their teeth during kindergarten hours, e.g. after breakfast together.
  • dentifrices with medical properties and for medical purposes can also be used according to the invention.
  • the connecting line from a soft and flexible hose material.
  • the hose diameter can be so thin that the hose is hardly thicker than the bristles.
  • the features of claim 5 relate to a development of the invention with the advantage that the same amount of dentifrice can always be dosed exactly and with the simplest means for each brushing operation.
  • toothbrushes can be produced whose hand-dosing devices have different grid step lengths.
  • screen steps with a shorter length are produced for children's toothbrushes than for adult toothbrushes.
  • the features of claim 6 are a development of the invention with the advantage of easy attachment of the toothbrush e.g. on the lapel or on a shirt pocket.
  • the first variant is characterized by a hollow container which holds the toothbrush as a single part.
  • the container is in two parts and consists of two caps or the like plugged into one another on the opening side.
  • the second variant consists in that the toothbrush handle is a shaft-like component of the container and that a cap can be placed over the shaft-like component of the container from the side of the brush head.
  • the further development according to claim 10 has the advantage that, on the one hand, the waste volume is reduced and, on the other hand, the dental care market is served with a further product which fully meets the requirements of modern dental hygiene.
  • Another advantage of the invention is that e.g. in the case of extremely economical use of dentifrices, a brush head which has been worn out prematurely can be replaced without further ado, and this without having to dispose of any remaining dentifrice.
  • the brush head can also be divided so that the bristles sit on an exchangeable plate plate.
  • the invention has recognized that in particular a bending stress occurs between the brush head and the handle, which if necessary. can be overlaid by tensile and compressive stress.
  • the proposed twist lock on the one hand easily absorbs these stresses, but also prevents an independent loosening between the brush head and handle during normal brushing operation.
  • Figures 1 to 6 show a toothbrush 1 with a handle 2, at the end of which there is a brush head 3.
  • the handle 2 has a receptacle 4 for a dentifrice 5.
  • the receptacle 4 is accommodated within the handle 2 of the toothbrush 1.
  • the receptacle 4 consists of the tube body 4.1, which is divided into a filled area 4.2 and an emptied area 4.3 by the manual metering device 7.
  • the connecting line 6 is arranged between the end of the receptacle 4 and the brush head 3, and the receptacle is provided with a hand dosing device 7 accessible from the outside, the function of which will be discussed in more detail below.
  • the hand dosing device 7 is accessible from the outside and serves to expel the dentifrice 5 from the receptacle 4 via the connecting line 6 to the brush head 3.
  • the manual metering device 7 consists of a cylindrical roller 8 which has a somewhat larger diameter in the central longitudinal region, the so-called roller center piece 10, than in the region of the two roller ends.
  • the handle 2 has a longitudinal slot 9 on its upper side, the width of which is dimensioned such that the roller center piece 10 with its two end faces on the Longitudinal slot 9 is present.
  • the end faces of the roller center piece 10 are thus guided laterally along the longitudinal guide 11, the longitudinal guide 11 being formed by the opposite slot edges of the longitudinal slot 9.
  • connecting line 6 ends in the brush head 3, according to. Fig. 1, by coming from the bristle attachment side 12 ends on that surface of the brush head 3 which faces the bristle side.
  • the connecting line 6 opens here with an opening 14 coming from the bristle attachment side 12 in the brush head 3.
  • the course of the connecting line is selected such that the mouth 14 neither projects beyond the bristle attachment area nor lags behind the bristle attachment area.
  • the mouth 14 is flush with the surface of the brush head 3.
  • the connecting line 6 can be realized by 2 intersecting bores in the toothbrush head 3 or in the handle 2.
  • the handle 2 in this embodiment is hollow (15), the receptacle 4 for the dentifrice being seated in the cavity 15 of the handle 2.
  • the representation in this partial figure is a cross section through the handle 2 of the toothbrush 1 in the longitudinal region in which the emptied region 4.3 of the receptacle 4 is seated.
  • the roller center piece 10 is laterally guided within the longitudinal slot 9 of the handle 2.
  • the roller center piece is provided with an enlarged outer diameter which is so large that it slightly projects beyond the upward-facing plane of the handle 2. This can be clearly seen in the lower left partial image of FIG. 1.
  • the roller center piece has a transverse corrugation in order to have a particularly non-slip grip option.
  • the cylindrical roller 8 is moved in the longitudinal direction 16 in the direction of the brush head 3 and, in accordance with the advance, a corresponding quantity of dentifrice from the receptacle 4.1 via the connecting line 6 in the direction of the brush head 3 expelled.
  • the transverse dimensions of the cylindrical roller 8 are chosen so that the cylindrical roller 8 extends over the entire width B of the handle 2, so that the available cavity 15 of the handle 2 can be filled with dentifrice in an optimal manner.
  • the user can immediately see from the outside how far the supply of dentifrice that is inside the tube body 4.1 is already used up. If the hand-held metering device 7 is located in the front area, that is, where the receptacle 4 is connected to the connecting line 6, it can be seen that the supply of dentifrices has run out and that a toothbrush according to the invention is about to be purchased.
  • the receptacle 4 is filled with a dentifrice which is filled in in a concentrated form. According to the concentration of the dentifrice can be adjusted so that normal wear a toothbrush provided that with the use of dentifrice the bristles of the toothbrush are so worn that for this reason it is also necessary to think about buying a new toothbrush.
  • FIGS 2 and 3 show another special feature.
  • the hand dosing device 7 cooperates with a raster 17 along its longitudinal guide, which allows movement of the hand dosing device 7 only in the sense of a consumption of dentifrice and blocks an opposite movement.
  • FIG. 2 which shows a longitudinal section through the handle 2 of the toothbrush 1
  • the handle in the region of the webs on both sides of the longitudinal slot 11 is provided with a grid 17 on the inside, which interacts with a grid stone 17.3.
  • the grid 17 consists of a sequence of identical identical sawtooth-shaped recesses 17.1, so that a sawtooth-shaped grid path is formed on the handle.
  • a raster stone 17.3 now runs on this sawtooth-shaped grid path, which has an engaging wedge 17.2 on its surface facing the grid path.
  • the engaging wedge 17.2 has an inclined surface which is able to slide on the inclined surface of the sawtooth-shaped recesses 17.1 when the grid stone 17.3 is pushed in the removal direction 18.
  • the dotted raster stone shows that the raster stone is slightly deflected downwards during the process of sliding the mutually facing oblique sliding surfaces.
  • the handle 2 of the toothbrush 1 according to the invention consists of an elastic material.
  • the grid stone 17.3 is under pressure in the drawn, deflected position, which causes the grid stone to attempt to evade.
  • the grid stone 17.3 slides in the direction of lower resistance on the Bevel the corresponding sawtooth-shaped recess 17.1 until it hits the sawtooth edge 17.5 with the raster stone edge 17.6.
  • the grid stone 17.3 has a bearing bore 17.4 in which a bearing pin 17.7 of the manual metering device 7 engages.
  • the bearing pin 17.7 in the bearing bore 17.4 allows the manual metering device to be rotated in the manner already described, but the grid stone 17.3 is always driven forward in the longitudinal direction of the handle 2 and always assumes a concrete end position. Each end position is determined by the location of the raster stone edge 17.6 on the sawtooth edge 17.5 that is hit.
  • the transverse corrugation not only is the circumferential force better transmitted to the manual metering device 7, but the transverse corrugation also causes an increase in the friction between the manual metering device 7 and the surface of the hose body 4.1 in the area in which the manual metering device 7 against the filled area 4.2 of the Hose body 4.1 is pressed.
  • the hose body 4.1 can be pressed completely together with the hand dosing device according to the invention, so that the two tube halves are placed essentially exactly flat on one another after the hand dosing device has been rolled over it.
  • the sawtooth-shaped grid path has a step length 20 which is essentially identical for all sawtooth-shaped recesses 17.1. It is preferably dimension the step length 20 so that the amount of dentifrice expelled per grid step is sufficient for a single tooth brushing.
  • step length 20 depends at least on the following factors: Target persons and concentration of the dentifrice.
  • the toothbrush body has a fastening clip 21 for attaching the toothbrush to a pocket, case or the like.
