Definitions

  • the invention relates to a hand brush for cleaning prostheses, in particular dental prostheses, with a bristle holder which is connected to a handle part.
  • the hand brushes known to date for cleaning prostheses are predominantly stick brushes. This also applies to brushes for cleaning dental prostheses, which are designed in the manner of toothbrushes and have a relatively small bristle area. Denture wearers, who are predominantly older people, complain about the difficult handling of known denture brushes. From the medical side it is required that brushes for cleaning prostheses are designed hygienically.
  • the invention has for its object to provide a hand brush for cleaning prostheses, in particular dental prostheses, which can be handled well and safely and fully meets hygienic requirements.
  • a hand brush of the type mentioned in the present invention in that the entire hand brush is made from recyclable, sterilizable and food-compatible plastic materials, the elastic bristles being made in one piece with a large-area bristle carrier and the bristle carrier being non-detachably connected to the handle part by means of a snap connection is.
  • the hand brush designed according to the invention is made in all its parts from similar plastic materials, so that old brushes as a whole can be fed to a recycling plant.
  • the hand brush according to the invention has an important hygienic advantage. Due to the one-piece design of the bristles with the bristle carrier, no holes in the bristle carrier are necessary for fastening bristles in which dirt and bacteria could become lodged. Bristles and bristle bodies can be boiled out of a soft plastic material suitable for foodstuffs with any degree of softness and can be sterilized as a one-piece injection molded part. Similar plastic materials are used for the handle part and the locking connection, so that the brush can be boiled out as a whole.
  • the large bristle surface in conjunction with a handle part that is easy to grasp, advantageously concentric and / or symmetrical to an axis of symmetry or plane of symmetry of the bristle part also allows older people easy and safe handling of the hand brush.
  • the bristle carrier can be connected in a non-detachable manner either by means of a locking coupling part or directly to the handle part.
  • the bristles can run out thin and pointed and can be molded onto a plate-like bristle body.
  • the plate-shaped bristle body can expediently have an edge web on its rear side facing away from the bristles, which is undercut to form an annular groove for the positive reception of a plate-shaped end of the latching coupling part or of the handle part.
  • the plate-shaped end of the snap coupling part into two halves that can be swiveled along a diameter line, each of which has a coupling web half protruding perpendicularly from the plate half, which lie against each other when the plate halves are aligned with one another and which have latching projections or latching recesses on their outer sides which, when the coupling web is pushed in by a suitable opening of the handle part, cooperate in a form-fitting manner with latching recesses or projections formed on the inside of the handle part.
  • the plate-shaped end of the locking coupling part By pivoting the two plate halves, the plate-shaped end of the locking coupling part can be placed against the back of the bristle carrier in such a way that the plate halves can be positively inserted into the annular groove of the edge web of the bristle body. Then the coupling web of the locking coupling part is then inserted into the suitable opening of the handle part, where it snaps in place and its two forces are prevented from detaching from each other again. If there is no latching coupling part between the bristle carrier and the handle part, the latter can be divided into two halves which can be pivoted relative to one another and which rest on their
  • each have locking knobs and matching recesses for mutual connection.
  • a plate rim formed thereon can be conveniently inserted into a corresponding locking groove on the bristle carrier before the halves are then non-detachably connected to one another.
  • a reliable sealing of the contact surfaces existing between the bristle holder and the handle part can easily be achieved in that the opening edge of the handle part and / or the edge web of the bristle holder have a molded sealing bead or a molded sealing lip on the outside.
  • the hand brush 10 consists of a handle part 11 and a bristle carrier 12, which are made as separate molded parts from plastic materials that are metal-free and therefore suitable for food, boilable and sterilizable.
  • the handle part 11 has an elongated spherical back 11.1, to which a recessed grip 11.2 is connected on all sides in the direction of the bristle carrier 12.
  • the handle part 11 is formed symmetrically with respect to a plane of symmetry of the bristle carrier 12 which is characterized by the section line II-II and which is designed as a plate which, for example, has a circular shape.
  • bristles 13 which taper to a point are formed directly on one side of the plate-shaped bristle carrier 12.
  • Bristle carrier 12 and bristles 13 are thus made in one piece from a soft plastic material.
  • the plate-shaped bristle carrier 12 On its rear side, the plate-shaped bristle carrier 12 is provided with an edge web 12.1, the end region 12.2 of which is angled inwards, so that the edge web 12.1 / 12.2 delimits an annular groove 14.
  • the inwardly angled edge area 12.2 of the edge web 12.1 forms a contact surface for the handle part 11 and is formed in this area with an elastic sealing bead 12.3. This sealing bead, the Prevents liquid from penetrating into the interior of the hand brush 10 can also be formed on the handle part 11.
  • a non-detachable connection of the handle part 11 to the bristle carrier 12 is created by a snap coupling part 15, which is shown individually and in a side view in FIG. 3.
  • the locking coupling part 15 consists of a plate 16, the dimensions of which are adapted to the plate-shaped bristle carrier 12 so that the plate according to the sectional view in FIG. 2 fits at least with the major part of its outer edge into the annular groove 14 formed on the bristle carrier 12.
  • the plate 16 is divided into two hinged halves 16/1 and 16/2 by a notch 17 running along a diameter line. This division is also made on a coupling web 18 projecting to one side of the plate 16 along a plane running through the notch 17.
  • the two halves of the coupling web 18 are designated 18/1 and 18/2.
  • both coupling web halves 18/1 and 18/2 are provided with a projecting locking web 19. If the two plate halves 16/1 and 16/2 are aligned in their common plate plane, the two coupling web halves 18/1 and 18/2 lie against each other. From this operative position, the two plate halves 16/1 and 16/2 with their coupling web halves 18/1 and 18/2 can be pivoted into an angular position shown in broken lines in FIG. 3. In this angular position, the two plate halves 16/1 and 16/2 can be pushed with their outer edge into the annular groove 14 of the bristle carrier 12 and then brought into their alignment position, in which the two coupling web halves 18/1 and 18/2 lie against each other.
  • the coupling web 18 can be inserted into a suitable recess 20 which is open towards the underside of the handle part 11.
  • Side walls of the recess are provided with latching recesses 21, into which the latching projections 19 of the coupling web halves 18/1 and 18/2 can snap, creating a permanent connection between the handle part 11 and the bristle carrier 12.
  • the plastic material used for the production of the locking coupling part 15 and the handle part 11 has sufficient elasticity, which allows a sufficient elastic deformation of these parts when the locking connection is formed.
  • FIG. 4 shows a hand brush with a handle part 30 formed from two halves 30/1 and 30/2.
  • the two halves 30/1 and 30/2 each have a plate-shaped edge 33 which, in a manner similar to the corresponding edge 16 of the latching coupling part 15 in FIG Annular groove of the bristle body 34 can be inserted.
  • the two handle halves 30/1 and 30/2 are pivoted in a manner similar to that of the halves of the locking coupling part 15, inserted into the annular groove of the bristle body 34 and then pressed together.
  • buttons 31 integrally formed on the inside of the halves 30/1 and 30/2 snap into recesses 32 which are likewise arranged on the inside of the halves 30/1 and 30/2, which results in a permanent connection between the bristle carrier 34 and the handle part 30 .
  • All halves 30/1 and 30/2 are completely identical, ie they always have knobs 31 on one side of their longitudinal axis of symmetry 35 and recesses 32 on the other side. On this way, two halves 30/1 and 30/2 always fit together. There is no need to produce differently shaped left and right halves.
