Definitions

  • the invention relates to a toothbrush according to the preamble of claim 1.
  • a toothbrush according to the preamble of claim 1 is known from DE-30 33 295 AI.
  • This toothbrush has a handle part, partially designed as a flexible storage container for toothpaste or the like, at the front end of which a brush head is provided which contains passage openings through which the toothpaste or the like can be discharged from the storage container into the brush head.
  • a channel is provided which extends from the handle part to the through openings in the brush head and which is produced, for example, by drilling, it being necessary to ensure that the channel communicates with the through openings in the brush head. The manufacture of such a brush head is cumbersome and time-consuming.
  • the invention is therefore based on the object of improving a toothbrush according to the preamble of patent claim 1 in such a way that it can be produced inexpensively and can be assembled in a simple manner.
  • the invention provides a toothbrush in which the brush head is preferably formed in two parts. This enables simple manufacture of the two parts forming the brush head.
  • a recess e.g. formed by milling or directly during the spraying process.
  • the two parts can be firmly connected to one another either by fastening pins and associated pin openings or by using an adhesive or by welding.
  • the handle part preferably consists of an essentially cylindrical element made of elastic material, which can be closed on one side facing away from the brush head by a closure cap or the like.
  • the cap can be easily removed to fill the handle part with toothpaste, tooth gel or the like, which ensures that the handle part can be refilled.
  • the brush head is preferably firmly connected to the handle part by a thread. This ensures replacement of the brush head and reuse of the handle part over a longer period of time.
  • the handle part can be colored, for example by using neon colors or the like.
  • the brush head consists of two parts, namely a brush part and a brush receiving part, the brush receiving part being integrally formed on the handle part.
  • Fig.l shows the brush head, the two
  • Figure 2 is a representation of the handle part in a sectional view with the associated end cap in side view
  • Figure 3 is a sectional view of the brush head along the
  • FIG. 4 is a sectional view of a modified embodiment of the brush head, the brush head parts are shown detached from each other, Fig.5a shows another embodiment of the invention
  • the toothbrush according to the invention consists of a brush head 1, which is shown in Figure 1, and a handle part 2, which is shown in Figure 2.
  • the brush head 1 preferably consists of two parts la, lb, which are made of a relatively hard plastic in a known manner.
  • the part of the brush head 1 denoted by la carries, according to FIG. 1, the bristles 5 pointing upwards and has at least one, preferably a plurality of through openings 6,7 connected, which lead to a recess 4 running in the axial direction of part la.
  • the recess 4 runs centrally in the part la and, together with a further recess 9, also axially and centrally relative to the part lb, defines a feed channel within the brush head 1.
  • the feed channel or loading channel, which is defined by the two recesses 4, 9 is designated by 10 in FIG.
  • the axially extending cutouts 4, 9 can each have a part-circular or V-shaped cross section. It is essential that the channel 10 is also laterally sealed, which is ensured by mutually opposite surfaces of the two parts 1 a, 1 b, as can be seen from FIG. 3. In Figure 3, these areas are designated 11 and 12.
  • pins 14, 15, 16 and pin receptacles or depressions 17, 18, 19 assigned to these pins 14, 15, 16 are assigned.
  • the outer diameter of the pins 14, 15, 16 and the inner diameter of the cutouts or bores 17, 18, 19 are matched to one another in such a way that a clamp connection is created and the parts 1 a, 1 b are thereby firmly connected to one another as soon as the two parts are plugged together.
  • the two parts 1 a, 1 b can be firmly connected to one another by using an adhesive which is applied either in punctiform or flat fashion in the area of the surface sections 11, 12.
  • an adhesive which is applied either in punctiform or flat fashion in the area of the surface sections 11, 12.
  • the channel 10 is only to be provided from this through opening 6 in the direction of the handle part 2, ie it does not extend over the entire one Length of the bristle field formed on the brush head.
  • the pins 14, 15, 16 are preferably designed as knobs protruding perpendicularly from the part 1 a.
  • the brush head 1 is provided with a thread, preferably an external thread 22, so that the brush head 1 can be screwed into an associated internal thread 24 of the handle part 2.
  • the handle rope 2 is hollow and cylindrical and consists of a flexible shaft, which makes it possible, by compressing the shaft, the material located in this handle part such as toothpaste, tooth gel, or the like in the direction of the brush head 1 and into the channel 10 relocate.
  • a closure cap 25 which can be screwed onto an external thread 26 on the handle part 2 by an internal thread 27 formed therein.
  • the grip part is preferably made of an elastic material which, after being compressed, is re-formed into the original, cylindrical initial shape.
  • the brush head 1 has an essentially circular cross section at its end facing the handle part 2, the channel 10 opening directly into the handle part 2.
  • the cutouts or depressions 4, 9 can obviously be defined during the spraying process or can also be produced subsequently by milling, since the surfaces 11, 12 in question are easily accessible. A cumbersome drilling or keeping clear of the recesses 4,9 forming the channel 10 is not necessary according to the present invention. According to the invention, it is possible to produce the brush head 1 in a variety of shapes, the channel 10 having a straight course according to FIG. 1, but also a curved course. It is assumed that the connection level between the two brush head parts la, lb is defined by the channel 10.
  • the toothbrush part 1b consists of an essentially sleeve-shaped element with a channel 10 which can be connected to an opening 6 of the brush head la, the brush head la being clipped onto a recess of the part 1b which is not further specified or can be put on in another way.
  • the brush head section 1b thus has an essentially bulbous shape between the brush field 5 and the connecting thread 22 ', that is, the channel has a curved course, accordingly the parts la and lb are formed.
  • the toothbrush according to the invention makes it possible not only to design the handle part 2 in a cylindrical but also in a different configuration and, moreover, to keep it in any color configuration.
  • 5a and 5b show a further variant of the toothbrush according to the invention.
  • the brush head 1 is formed in two parts and consists of a flat or plate-shaped element 1 a 'on which the bristles 5 are fixed.
  • the plate 1 a is rectangular, for example, and is equipped with one or more through openings 30 for the toothpaste or tooth gel.
  • the associated part 1b ' also has a substantially rectangular shape Receiving area and is provided on a front section and a rear section each with a transverse to the axis clamping rib 31 or 32, as can be seen from Figure 5a, which have a distance which corresponds approximately to the length of the part la '.
  • the part 1b ' is designed as an extension of the handle part 2, the handle part 2, for example, providing an extension 33 which is offset downwards relative to the axis of the handle part 2 and which serves with an integrated channel for carrying out the toothpaste or the like.
  • the two-part design of the brush head 1 ensures on the one hand the exchange of the brush field and on the other hand the use of brushes of different hardness.
  • the manufacture of the toothbrush described is also simplified in that the bristle field with part la can be produced independently of the handle part 1 with part lb 'of the brush head.
  • a closure cap 25 At the end of the handle part 2 there is a closure cap 25 according to the described embodiments.
  • the handle part 2 thus forms an essentially cylindrical cavity which tapers in the direction of the brush head 1 and merges into the channel 10, which leads to at least one through opening 6 through which the tooth gel or toothpaste is displaced vertically upwards into the brush field can be.
  • a so-called slip brake is provided on the handle part 2 or on the surface of the area la which is gripped with the thumb during the actuation of the toothbrush, i.e. a nub-like material that is sprayed on accordingly and ensures safe movement of the toothbrush during the toothbrushing process.
