Definitions

  • the invention relates to a brush, in particular toothbrush, with the features of the preamble of claim 1.
  • Such a toothbrush is from the EP 0 933 044 A2 known.
  • a disadvantage of this toothbrush is that it consists of relatively many parts and therefore is expensive to manufacture.
  • the invention is therefore based on the object to provide such a toothbrush, which consists of a few parts and therefore is easier and cheaper to produce. This object is achieved with a brush having the features of claim 1.
  • a preferred embodiment of the invention is characterized in that the storage space on the side opposite the upper part is limited by a bottom part movable only towards the upper part and that the channel is always open from the storage space to the brush head and that in the channel a cross-sectional constriction is provided, which generates a flow resistance which is greater than the movement resistance of the bottom part in the direction of the brush head. In this way, the back flow of the agent is inhibited in the pantry.
  • the pumping process is, as in itself from the EP 0 933 044 A2 is known, carried out by pivoting the upper part relative to the lower part, by the pivoting of the upper part relative to the lower part of the storage space is reduced in the region of the elastic wall portion, so that the agent is pressed through the channel to the brush head.
  • the channel only has to have such a narrow channel at least in sections that, given the viscosity of the agent used, sufficient flow resistance is present prevents excessive back flow of the agent when after a pumping operation, the upper part is raised or stretched relative to the lower part again.
  • a volume compensation must be created by suitable measures, for example by the fact that the storage space is limited on the side opposite the upper part of a bottom part movable only towards the upper part, otherwise the agent would be sucked back out of the canal.
  • the upper part and the lower part have rigid wall sections, which are connected to one another via the joint and between which the elastic wall section is arranged.
  • the rigid wall sections and the hinge are formed from a one-piece part. They can therefore be produced in a single injection process, wherein the joint can be carried out in a known per se, for example as a film hinge.
  • the channel is bounded directly by the rigid wall sections and the elastic wall section. That is, there are no further protective or separating layers between the rigid wall sections and the elastic wall section, which further simplifies the production.
  • the lower part and the upper part can be formed with their rigid portions of one-piece parts and limit the reservoir or the channel.
  • the entire brush apart from the movable bottom part and the bristles on the brush head, can be made in a simple embodiment of a single part, on which only the elastic wall portion must be attached, which can be done by a second injection process in a simple manner.
  • the width of the joint is among other things of the diameters of the upper part and the lower part and their length and, of course, also dependent on the desired stability of the joint against lateral kinking. Preferred in the invention, when the width of the joint is between 1/6 and 1/2, preferably about 1/3, of the diameter of the lower part and / or if the width of the joint between 1/5 and 2/3, preferably about 1/2, the diameter of the shell is. These dimensions ensure in the usual dimensions of such brushes sufficient stability of the joint and functionality of the brush.
  • the brush according to the invention has an upper part 1 and a lower part 2, which are connected to each other via a hinge 3 on.
  • the upper part 1 and the lower part 2 are made of a hard and rigid material, such as polypropylene, and preferably made in one piece with the hinge 3, which may be in the form of a film hinge.
  • a brush head 4 with bristles 5 At the upper end of the upper part 1 is a brush head 4 with bristles 5, the number and length of each desired application depends.
  • the lower part 2 is cylindrical and encloses a storage space 6 which is delimited on the side opposite the upper part 1 by a bottom part or piston 7.
  • the bottom part 7 is ideally a sliding on the inner surface 8 of the wall of the lower part 2, which is movable for example by suitably shaped ribs on the inner surface 8 and / or claws 9 or the like only in the direction of arrow 10 to the upper part 1, whereas a movement in the other direction is prevented by the ribs and / or claws 9.
  • the upper part 1 delimits a brush head 4 towards narrowing channel 11, which extends from the storage space 6 to the brush head 4 and at the end 18 has its smallest cross-section.
  • an extension in the form of an elastic tube 12 can be arranged at the end of the channel 11, on the one hand, in order to adjust the flow resistance in addition to the channel 11 in addition, on the other hand, in order to promote the agent further towards the end of the bristles 5 can.
  • the tube can also perform a similar function as a valve if it is elastic enough to fold together.
  • an elastic wall portion 13 is arranged in the region of the joint 3, on the one hand to the edges 14, 15 of the rigid wall sections 16 and 17 of the upper part 1 and the lower part 2 and on the other hand to the joint 13 connects.
  • the elastic wall section 13, which consists for example of a thermoplastic elastomer, can be injection-molded directly onto the wall sections 16 and 17 by means of a per se known injection molding method and thus be permanently connected thereto.
  • the upper part 1 is bent relative to the lower part 2, as in Fig. 5 and 6 is shown.
  • the upper part 1 buckles at the joint 3 with respect to the lower part 2 and a part of the elastic wall portion 13 and to a certain extent also the bending-resistant portion 16 adjoining the edge 14 are pressed slightly into the storage space 6. Since the bottom part 7 can not escape downwards, the agent is forced through the channel 11 and the tube 12 to and between the bristles 5.
  • the upper part 1 is released, it is moved back into its starting position by the elastic wall section 13, with the elastic wall section 13 simultaneously moving outwards again and thus increasing the volume in the storage space 6.
  • the flow resistance in channel 11, in the illustrated embodiment primarily the flow resistance in the region of the brush head 4, is so great that the agent is not sucked back through the channel 11. Rather, the flow resistance and the movement resistance of the bottom part 7 are set to one another such that the bottom part 7 is sucked a small distance in the direction of the arrow 10.
  • the flow resistance of the channel 11 is determined primarily by the flow cross-section in the region of the brush head 4. It is of course possible, alternatively or additionally at other locations of the channel 11, to take measures, e.g. a valve, which influence the flow resistance in channel 11.
  • the channel 11 can be filled by pressing on the bottom part 7 until the backflow resistance in the channel 11 is so large that not the agent sucked back from the channel 11 but the bottom part 7 is sucked in the direction of the arrow.
