Definitions

  • the invention relates to a toothbrush with a handle that has a Connecting part with a brush head having an elongated bristle bed is connected to first bristle bundles on both outer sides of the bristle bed, and with longer longer ones arranged between the two outer sides Bristle bundles and shorter third bristle bundles, being in the longitudinal direction of the Bristle bed successively second bristle bundle and third bristle bundle are provided so that a wave-like profile results in the longitudinal direction.
  • a toothbrush is known from EP 0 619 711 B1.
  • EP 0 619 711 B1 therefore describes one in the longitudinal direction of the bristle bed known sinusoidal profile of the bristle bundles of a toothbrush, at which the points of maximum amplitude essentially with the gaps coincide, which are formed between the teeth of the user. All bristles have rounded ends to prevent tooth damage and avoid gums due to sharp edges. It will be an improvement cleaning performance in the interdental area, because the superscript Bristles penetrate better into the recesses between the teeth can.
  • the invention has for its object a toothbrush with an improved Cleaning performance, especially for the interdental spaces, but also for the Gum line, to develop.
  • This task is the toothbrush of the type mentioned solved according to the invention in that the first bristle bundles with one another have substantially the same length and with spliced bristle ends are provided.
  • the first as well as the second and third bristle bundles consist of the same or a comparable material, namely from high-quality plastics, in particular made of nylon 66 or the like.
  • the diameter of the Bristles (filaments) are preferably 0.1 to 0.25 mm, in particular 0.15 to 0.225 mm.
  • Each bundle of bristles comprises 40 to 60 bristles, the so-called anchor methods 20 to 30 bristles are preferred.
  • the upper ends of the outer first bundle of bristles above the lowest ends of the inner shorter third bristle bundles are arranged. Secondly, it is from Advantage if the upper ends of the outer first bristle bundle highest ends of the inner shorter third bristle bundle exceed at most 1 mm and in particular up to the extend the highest ends of the inner longer second bristle bundle.
  • the outside bristles are short enough to hold the Internal bristles for cleaning the interdental areas and the outside of the Teeth to take effect. If the outer bristles were too long, it would set a "stilt effect" so that the ends of the inner bristles do not More contact with the outside of the teeth and especially with the interdental spaces have. Second, the outside bristles are too long enough to allow the inner bristles to contact the gum line prevent. Third, limit bristles with such a minimum length the "troughs" formed by the inner bristles, so that the on the inner bristles applied toothpaste to improve cleaning performance longer is available and not as quickly as with conventional toothbrushes Bristle field leaves.
  • the splice depth of the outer first Bristle bundle is up to 4 mm, in particular up to 2 mm. Is an advantage also if there are 5 to 10 outer first bristle bundles per bundle row are provided.
  • the inner second and third bristle bundles preferably have one Length (cutting height), measured from the bristle base to the ends, from 8 to 14 mm, in particular from 9 to 12.5 mm. To achieve a particularly good one Cleaning performance is suggested that the length difference between the second and third bristle bundles is 1 to 2 mm.
  • the ends of the the second and / or the third bristle bundle are - in contrast to the spliced ends of the first bristles - not spliced, but rounded to one ensure additional safety against injury to the gums.
  • the inner second and third bristle bundles arranged in rows transverse to the longitudinal axis of the bristle bed are 1 to 2 rows of third bristle bundles with short bristles, especially with the same bristle length, with 1 to 2 rows of second bristle bundles alternate with long bristles, especially with the same bristle length.
  • the area of the shorter one should third bristle bundle, measured in the longitudinal direction of the bristle bed between the adjacent longer second bristle bundles, a length of 6 to 10 mm to have.
  • the distance between the centers of neighboring bristle bundles, measured at the bristle base, should be 1.5 to 3.5 mm, in particular 2.0 to 3.0 mm. With this distance When brushing the teeth, such flexibility of the bristle bundles is achieved, which further improves cleaning performance. It is also preferred that 20 to 30 inner bundles of bristles, in particular 23 to 28 bundles of bristles, are provided are.
  • the ergonomics of the toothbrush is also for one good cleaning result important. This applies in particular to the cleaning of the Oral cavity in the back area of the sitting teeth, i.e. the cheek and wisdom teeth.
  • the connecting part between the bristle bed and the handle which is also called web, should therefore have a diameter of no more than Have 10 mm.
  • a web with an oval cross section is preferred, the longer axis lies in the plane of the bristle bed and has a length of 5 to 7 mm should have.
  • the shorter axis perpendicular to it has an advantage a length of 4 to 6 mm.
  • the ratio of long to should be on the handle short axis be about 1.1 to 1.5 to 1. Because the longer axis in the plane of the bristle bed is a lateral evasion of the bristle bed at Brushing the teeth hampers, but the bristle bed gives way perpendicular to this level relieved so that too much pressure on the toothbrush is balanced becomes.
  • the connecting part (the web) can vary from the handle attachment to the attachment of the Taper the bristle bed to 60% of the original diameter.
  • the angle between the bristle bed and the web on the one hand and the Handle on the other hand should be in the sense of ergonomics of the toothbrush at 3 ° to 10 °, in particular at 5 ° to 9 °, so that in particular the molars are much easier to reach.
  • the through the bristle bed, the web and the Handle formed plane is preferably perpendicular to the plane of the Bristle bed.
  • the toothbrush consists essentially of four parts in a manner known per se, namely an elongated flat bristle bed 1 with 40 bundles of bristles 2, 3, 4 is equipped and connected to the handle 6 via a connecting part (web) 5 is.
  • the one piece with the bristle bed 1 is made of Plastic injection molded connector 5 inside of a transparent Plastic injection molded handle 6 anchored.
  • the height of the bristle bundles 2, 3, 4 made of polyamide and their Arrangement on the bristle bed 1 can best be seen in FIGS. 3 and 4 out.
  • the inner long bundles of bristles (second bristle bundle) 3 are dashed in Figure 3, the inner short Bristle bundle (third bristle bundle) 4 with a small circle and the outer spliced bundle of bristles (first bundle of bristles) 2 with a zigzag line characterized.
  • the length differences of the bristle bundles are shown in FIG. 4 especially clear.
  • the rear outer ones in this illustration protrude here Bristle bundle 2 beyond the front short third bristle bundle 4 and are therefore visible at all in Figure 4.
  • the ends of the outer first bristles are spliced with a Splice depth of about 1 mm. It is also important that the area of short third bristle bundle 4, measured in the longitudinal direction of the bristle bed 1 between the adjacent long second bristle bundles 3, has a length a of 8 mm ( Figure 3).
  • the bristle bundles 2, 3, 4 are anchored in bores 8, which have a diameter of 1.7 mm and a bristle bundle neighboring from center to center measured distance of 2.5 mm.
