fig1 shows a perspective view of an interdental cleaner 10 , which has a rod - like support 11 consisting of a plastic and at the rear end of which , which is the right - hand end according to fig1 , a grip section 13 is formed , by which a user can grip the interdental cleaner 10 . a cleaning device 12 is mounted on the rod - like support 11 at the front end located axially opposite the grip section 13 , the left - hand end according to fig1 . this [ cleaning device ] has a cover 14 of the support 11 , said cover 14 preferably consisting of a flexible plastic and having a structuring 19 on its outer side . fig2 through 4 show details of the design and of the components of the cleaning device 12 and of the structuring 19 . the cover 14 has on its outer side radially outwardly projecting , freely projecting fingers 15 , which consist of the same material as the cover 14 and is made in one piece with this , as this is shown in fig4 . the fingers 15 have a radially outwardly tapering conical shape ( shown , for example , as a circular cone here ). six fingers each are arranged distributed over the circumference of the cover 14 in a plane extending at right angles to the longitudinal axis l of the support 11 in the exemplary embodiment shown , and they form a finger crown 17 . as is shown in fig2 , a plurality of finger crowns 17 arranged at axially spaced locations are provided in the axial longitudinal direction . a bristle crown 18 each is arranged between adjacent finger crowns 17 . each bristle crown 18 comprises six bristle bundles 16 , which are embedded in the support 11 with their radially inner ends ( see fig3 ), pass through the cover 14 and project from this radially outwardly . as is shown in fig4 , the freely projecting length of at least some of the bristle bundles is greater than the freely projecting length of the fingers 15 , so that the free ends of the bristle bundles 16 project radially outwardly over the fingers 15 by a measure m , which is in the range of 0 . 1 mm to 1 . 5 mm . fig5 shows a view similar to that in fig4 , but the fingers 15 project radially over the bristle bundles 16 by a measure n here . the measure n is in the range of 0 . 1 mm to 1 . 5 mm , so that the fingers 15 project radially outwardly over the bristle bundles 16 . as is shown in fig3 and 4 , the fingers 15 and the bristle bundles 16 are oriented in the circumferential direction such that one bristle bundle 16 each is arranged in the projection between two fingers 15 and one finger 15 is arranged between two adjacent bristle bundles 16 . fig6 shows a second exemplary embodiment , which differs from the first exemplary embodiment according to fig1 through 4 in the arrangement and orientation of the bristle border . according to fig6 , the bristle border is formed by a plurality of rows of bristles 21 , which extend in the longitudinal direction of the cover 145 and of the rod - like support 11 and which extend in a straight line in the longitudinal direction of the cover 14 and form a tight , gapless “ bristle wall .” according to the exemplary embodiment shown , four straight rows of bristles are distributed uniformly over the circumference of the cover 14 , and a row of fingers 15 each is arranged between two rows of bristles located adjacent to one another in the circumferential direction . fig7 shows a variant of the embodiment according to fig6 and differs from this in that the rows of bristles 22 extend helically in the longitudinal direction of the cover 14 and thus wind around this . a row of fingers 15 each is provided between two rows of bristles 22 located adjacent to one another in the circumferential direction in this case as well . fig8 through 10 show a third exemplary embodiment , which is a variant of the exemplary embodiment according to fig1 through 4 and differs from these in that the bristle crowns 18 are formed by a plurality of individual bristles 20 here , which are arranged tightly packed such that the bristle crowns 18 are formed in the manner of a continuous bristle disk , which extend at right angles to the longitudinal axis l of the cover 14 . as is shown in fig9 , the individual bristles 20 are embedded at their radially inner ends in the material of the support 11 and pass through the cover 14 and project freely from this radially . fig1 shows a variant of the embodiment according to fig8 and differs from this in that the bristle crowns 18 or bristle disks have a substantially larger dimension in the axial direction of the cover 14 or support 11 , i . e ., they are substantially thicker and have a thickness s in the range of 0 . 5 mm to 1 . 0 mm . the fingers 15 , on the one hand , and the bristle border , i . e ., the bristle bundles 16 and individual bristles 20 , on the other hand , were each formed and mounted or held independently from one another in the exemplary embodiments shown hitherto . fig1 and 13 show another exemplary embodiment of the interdental cleaner according to the present invention , in which individual bristles 20 are provided , through which the fingers 15 pass . the interdental cleaner 10 has the design mentioned with the rod - like support 11 and with the cover 14 , which carries a plurality of radially outwardly projecting fingers 15 formed in one piece on its outer side . as is shown in fig1 , two individual bristles 20 pass through each finger 15 . the individual bristles 20 are embedded at their radially inner ends in the material of the support 11 and extend from there radially outwardly through the finger 15 and exit at the radially outer end thereof , i . e ., at the tip of the finger 15 , and project radially from this . the individual bristles 20 and the corresponding finger 15 mutually affect one another in this manner by the individual bristles 20 imparting a higher bending resistance to the finger 15 and the finger 15 supports the individual bristles 20 over a substantial section of its axial length , so that the risk of kinking of the bristles 20 is reduced . fig1 shows a variant of the embodiment according to fig1 . two individual bristles 20 extend through the fingers 15 in the radial direction and exit from the finger at the outer tip of the finger 15 in this case as well . however , the individual bristles 20 are not held with their inner ends in the material of the support 11 , but they pass through the support 11 and a finger 15 arranged on the opposite side and exit from it [ the support ] at the radially outer end thereof . the individual bristles 20 are thus arranged within the support and are held in same in a middle area . the bristle bundles 16 and / or individual bristles 20 and / or fingers 15 were arranged in circumferential finger crowns in the above - mentioned exemplary embodiments . fig1 shows now an exemplary embodiment in which the fingers are arranged each offset in the axial direction or the longitudinal direction of the interdental cleaner in relation to the adjacent fingers . this applies to the bristle bundles 16 and / or individual bristles . it is achieved in this manner that when the interdental cleaner is pushed axially into an interdental space , the fingers 15 come into contact with the surface of the tooth one after another , as a result of which the resistance is reduced . this also applies to the bristle bundles 20 . fig1 shows alternative possibilities for fastening a bristle bundle 16 in the material of the support 11 . a broadened head 23 , with which the bristle bundle 20 is embedded in the material of the support 11 , so that high resistance to pulling out is achieved in a positive - locking manner , is formed at the radially inner end of the bristle bundle 16 in a first embodiment shown in the top part of fig1 . according to a second embodiment shown in the center of fig1 , the bristle bundle 20 is so long that it passes completely through the material of the support 11 and projects from this on opposite sides . according to a third embodiment shown at the bottom of fig1 , the bristle bundle is bent in a v - shaped pattern and embedded with the base section of the v shape in the material of the support 11 , with the legs of the v shape projecting radially . a very high level of safety against pulling out is achieved here as well . fig1 shows another embodiment of the fastening of the bristle bundle 16 . the bristle bundle 16 is bent in an l - shaped pattern , and one leg of the l shape extends in the longitudinal direction of the interdental cleaner within the material of the support 11 , while the other leg of the l shape extends at right angles thereto , i . e ., radially to the longitudinal direction of the interdental cleaner and projects radially . according to fig1 , the bristle bundle 16 is bent in a u - shaped pattern and has a preferably horizontal base section and two legs projecting therefrom . the bristle bundle 16 is embedded with the base section in the material of the support 11 and is held in same , while the two legs project radially . while specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention , it will be understood that the invention may be embodied otherwise without departing from such principles .
