Definitions

  • the invention relates to a filling toothbrush or a filling shaving brush with a tubular handle receiving the toothpaste or the shaving soap, on one end of which a removable bristle carrier provided with bristles is rotatably mounted, which extends from the bristles into the cavity of the handle to the end has leading connecting channel on which a metering piston is axially displaceable relative to the bristle carrier by rotating the handle.
  • the metering piston is connected to the connecting channel via a thread and by friction, i.e. by friction, rotatable with the handle, but axially movable against it due to the threaded connection.
  • the invention is based on the object of creating a filling toothbrush or a filling shaving brush of the type mentioned at the outset, which are easier to use, in particular are quickly ready for operation, and in which operating errors are avoided. Furthermore, it should be easy to refill.
  • metering piston is secured against rotation relative to the connecting channel and is connected to the handle by a thread, in that the end of the handle remote from the bristle holder is closed by a removable cover, and in that the handle is designed symmetrically such that the Lid can be placed on both ends.
  • a positive connection is provided between the connecting channel and the metering piston, which allows an axial displacement of the metering piston relative to the connecting channel, but prevents rotation between these two parts.
  • the threaded connection is provided between the inner wall of the handle serving as a storage space and the outer surface of the metering piston.
  • Refilling is also possible by means of the invention. Due to the fact that the handle is designed symmetrically so that the lid can be placed on both ends, the handle is emptied after emptying, i.e. when the dosing piston has reached the other end position, simply turn it over. The dosing piston is then again at the end that is to be connected to the bristle holder. The other end is open and can be used for filling. After filling, the lid is put on. In this case too, it is not necessary to screw the connecting channel through the metering piston, since the axial movement can be carried out unimpeded.
  • the filling toothbrush in such a way that the axis of the bristle holder is offset from the axis of the handle. This ensures that the moment generated by the force acting on the bristles during brushing counteracts the moment caused by the displacement of the axes, so that rotation of the brush or the bristle carrier around the axis of the handle is prevented.
  • the shaving brush in such a way that a closure (surface enlarger) distributing the shaving soap can be placed on the end of the connecting channel. This ensures good distribution in terms of increasing the surface area of the shaving soap, i.e. the shaving soap should be in the area of all the bristles from the start if possible.
  • the thread on the inner wall of the handle can either be formed beforehand, for example by injection molding when it is made from plastic, or it can be a self-tapping thread which is produced by the thread of this piston during the first movement of the piston.
  • Correspondingly soft plastic must then be provided in sections or longitudinal strips in the area of the inner wall of the handle, which enables the thread to be formed reliably.
  • the thread of the handle can be formed without cutting by cutting through the thread of the dosing piston. However, it is also possible to form the thread of the handle only on some sections running in the longitudinal direction. In this case, the thread can be produced from the start by injection molding, but the tool can be designed in such a way that it can be rotated out of the region of the sections which have the thread and then pulled out of the cavity of the handle.
  • the filling toothbrush shown in the drawing consists of a bristle carrier 1 with bristles 2, in the area of which a tube 3 leads to the transport of the toothpaste.
  • the hose 3 merges into a fixed connecting channel 6, which has a non-round cross section.
  • a handle 4 is placed on the bristle carrier 1, which can be provided with a corrugation 10, which serves as a storage container for the toothpaste.
  • the connection between the handle 4 and the bristle carrier 1 takes place in such a way that a separation in the axial direction is only possible by applying appropriate force.
  • the handle is easily rotatable relative to the bristle holder.
  • a metering piston 5 is provided in the handle, which has an external thread which is in engagement with an internal thread 7 on the inner wall of the handle.
  • the cross section of a central opening in the metering piston 5 is adapted to the cross section of the connecting channel 6, so that the metering piston 5 is axially displaceable on the connecting channel 6, but is not rotatable relative thereto.
  • the snap connection between the bristle carrier 1 and the handle 4, which allows rotation, is designated by 8.
  • the piston 5 When the filling toothbrush is to be put into operation and there is a handle filled with toothpaste, the piston 5 is at one end (left in FIG. 1).
  • the cross section of the hole adapted to the cross section of the connecting channel 6 is closed by a destructible film.
  • the connecting channel is inserted into the hole, the film being destroyed.
  • the snap connection is established.
  • the connecting channel then lies with its open end in the vicinity of the other end of the handle 4.
  • the metering piston 5 presses toothpaste into the connecting channel into the area of the bristles 2.
  • the embodiment according to FIG. 1 shows that the internal thread 7 passes through at both ends. Both ends are practically the same. If the handle in this embodiment according to FIG. 1 is completely empty, the lid 9 can be unscrewed. The handle can then be turned through 180 ° and reattached to the bristle holder 1 or to a new bristle holder. The metering piston 5 is then again at the end connected to the bristle carrier 1. The other end is open and can be filled. After filling, this end is closed by screwing on the lid 9.
  • the filling toothbrush according to the invention allows an automatic supply of toothpaste to the bristles as long as toothpaste is in the handle.
  • the handle which is practically a cartridge, is a refillable part.
  • the connection and design of the metering piston in relation to the connecting channel and the handle are selected so that simple commissioning and simple operation are possible.
  • FIGS. 2 to 6 differs only slightly from that according to FIG. 1.
  • annular projections 11 are provided at both ends, which are used for snap connection with annular grooves 12 in the bristle carrier 1.
  • a lid 9 (Fig. 5) is provided with a thread 16 for screwing into the handle, on the side on which the bristle holder is not seated.
  • the bristle carrier 1 is prevented from rotating about the axis of rotation 4b during use of the filling toothbrush . Such a rotation would not only impair the use during brushing or make it impossible, but would also cause the metering piston 5 to move undesirably.
  • FIGS. 7 to 13 relate to different thread configurations.
  • FIGS. 8 and 12 corresponds to that according to FIG. 1.
  • the internal thread provided on the inner wall and designated by 14 passes through and is produced by injection molding during the manufacture of the handle 4 from the beginning.
  • the internal thread 15 is only provided on some sections running in the longitudinal direction, so that after the handle 4 has been produced, the core can be rotated in a corresponding shape and pulled out of the mold.
  • FIG. 14 shows a bristle carrier with a connecting channel 6a for a filling shaving brush.
  • the outlet opening for the shaving soap lies in the axis of rotation since there is no fear of a relative rotation between the bristle carrier 21 and the handle.
  • a closure 23, 24 can be placed on the projection 20, which has a slotted opening which ensures distribution (surface enlargement) of the shaving soap so that it reaches all bristles 22 as far as possible.
  • the drawing is drawn apart.
  • the separately shown part 24 is formed in one piece with the extension 23 and this extension 23 is seated on the projection 20.
  • This extension formed by the parts 23 and 24 can also be referred to as a "flute closure" because the line for the shaving soap is in between the parts 23 and 24 provided slot ends and the upper end is cut off obliquely like a flute.
  • the end of the filling channel which is denoted by 17 in FIGS. 2 and 14, has a smaller diameter, so that the metering piston 5 is no longer secured against rotation. When the metering piston 5 has reached its end position, destruction is prevented.
