  • Fig. 7C is a sectional view illustrating principal parts in a handle head, in which rubber-like bar bristles are set independently of each other.
  • the angle of inclination is preferably 2 to 15°, particularly 2 to 5° in an outside direction of a longitudinal edge of a handle head based on a line perpendicular to the bristle-setting surface of the handle head.
  • the degree of the projection is preferably about 0.5 to 3.0 mm.
  • the rubber-like bar bristles be set alternately with the bristle bundles into at least parts of longitudinal edge portions on the bristle-setting surface, since the rubber-like bar bristles are prevented from being concentrated at one place, so that they become easy to reach interdental papillae.
  • the rubber-like bar bristles are not inclined in the outside direction, they are preferably set alternately with bristle bundles in an upright position with their tips projected from the tips of the bristle bundles by about 0.5 to 3.0 mm into at least parts of longitudinal edge portions on the bristle- setting surface.
  • any rubber-like bar bristles may be used irrespective of their specific shape so far as they each have a cross-sectional shape that its face is wider at the peripheral side than at the central side in order for the rubber-like bar bristle to be easier to deflect in the outside direction of the handle head than in the inside direction thereof upon use.
  • those having substantially a triangular or trapezoidal shape in section are particularly preferred because they are excellent in the ability to deflect in the outside direction. In this case, it is also preferred from the viewpoint of having a soft feel in the mouth that each corner be suitably rounded.
  • the rubber-like bar bristles may be in the form of a square bar having the same thickness on the whole.
  • the square bar be tapered off upward, and from the viewpoint of having a soft feel like the above that the tip thereof be also suitably rounded.
  • a mixed bristle part composed of rubber-like bar bristles and bristle bundles having softness to an extent that gums are not damaged is formed in a peripheral portion on the bristle-setting surface of a handle head, and a bristle part composed of bristle bundles harder than the bristle bundles set in the peripheral portion is formed in the central portion on the bristle-setting surface of the handle head, it is simple and advantageous that a difference in hardness between the bristle bundles set in the central portion and the bristle bundles set in the peripheral portion is made by, for example, suitably varying the resilience, length or thickness of the bristle bundles set in the central and peripheral portions , or the thickness of the individual bristles making up the bristle bundles irrespective of specific imparting means thereof.
  • the soft bristle bundles set in the peripheral portion may also be formed in plural rows inward from the peripheral end.
  • the rubber-like bar bristles set in combination with the soft bristle bundles set in the peripheral portion may be set over the overall periphery of the bristle-setting surface.
  • it is further preferred from the viewpoint of achieving an efficient massaging effect on gums that they be set in only longitudinal edge portions on the bristle-setting surface .
  • a connected member of rubber-like bar bristles the bases of which have been connected to each other be set into the handle head in such a manner that the bristle parts of the connected member are fitted into through-holes cut in the handle head from the side of the back surface of the handle head so as to project from the bristle-setting surface, since they can be set efficiently and certainly.
  • FIG. 1A and IB illustrate a first embodiment.
  • Rubber-like bar bristles 20 are set with an inclination of about 4° toward the outside from respective longitudinal edge portions 10b into the longitudinal edge portions 10b opposed to each other on the bristle-setting surface 10a of a handle head 10 connected to the tip of a handle 11.
  • the tips of the rubber-like bar bristles 20 are arranged at substantially the same level as the tips of bristle bundles 30 set in an upright position into the bristle-setting surface 10a, and moreover the rubber-like bar bristles 20 are set alternately with the bristle bundles 30 in the same row at the longitudinal edge portions 10b.
  • the rubber-like bar bristle 20 is a straight bar not curved up to the tip, force is easy to apply to gums in all of vertical, lateral and oblique directions, so that a high massaging effect is achieved, and moreover the bar bristles 20 do not prevent the bristle bundles 30 set into the bristle-setting surface 10a from removing sordes on teeth, since they are inclined toward the outside.
  • the rubber-like bar bristles 20 each have a cross- sectional shape of substantially a triangular form that its face is wider at the peripheral side of the handle head 10 than at the central side, wherein a corner thereof is opposed to the central side, and a side corresponding to it is located substantially in parallel with the longitudinal edge portion 10b of the handle head 10 in order for the rubber-like bar bristles to be easier to deflect in the outside direction of the handle head 10 than upon use.
  • the corners of the substantial triangle are suitably rounded so as to have a soft feel .
  • Fig. 2 illustrates another example of the cross- sectional shape of the rubber-like bar bristle 20.
  • This bar bristle has substantially a trapezoidal shape and is set into the bristle-setting surface with the shorter side 20x of the parallel sides located on the central side of the handle head 10 and with the longer side 20y thereof located on the peripheral side of the handle head 10.
  • the rubber-like bar bristles 20 are gradually tapered off upward, and tips 20c thereof are rounded.
  • the rubber-like bar bristles 20 may be formed irrespective of materials such as rubber and rubber-like synthetic resins so far as the material has deflection resilience.
  • preferable examples of the material include styrene*butadiene rubber, ethylene* propylene rubber and silicone rubber.
  • Reference numeral 30 indicates a bristle bundle, and a proper number of the bristle bundles is set into the bristle-setting surface 10a of the handle head 10 as before.
  • a material for the bristle bundles 30 natural fur or artificial bristles made of nylon, polybutylene terephthalate or the like may be used irrespective of the kind of the material.
  • Fig. 3 illustrates a second embodiment, and the toothbrush of this embodiment is constructed in the same manner as in the first embodiment illustrated in Figs . 1A and IB except that the tips of the rubber-like bar bristles 20 are projected by about 2 mm from the tips of the bristle bundles 30 set in an upright position into the bristle-setting surface 10a. More specifically, the rubber-like bar bristles 20 according to this embodiment are set with an inclination toward the outside of the longitudinal edge portions 10b on the bristle-setting surface 10a and with the tips thereof projected from the bristle bundles 30.
  • Fig. 4 illustrates a third embodiment
  • the toothbrush of this embodiment is constructed in the same manner as in the second embodiment illustrated in Figs . 3A and 3B except that the rubber-like bar bristles 20 are set in an upright position into the bristle-setting surface 10a without inclining them. More specifically, the rubber- like bar bristles 20 according to this embodiment are set alternately with bristle bundles 30 in an upright position into the bristle-setting surface 10a with the tips thereof projected from the tips of the bristle bundles 30.
  • Fig. 5 illustrates a fourth embodiment, wherein bristle bundles 30a having softness to an extent that gums are not damaged and rubber-like bar bristles 20 are set alternately with each other by only one row in the same row along the periphery of the bristle-setting surface 10a excluding an end lOd of the bristle-setting surface 10a on the handle side.
  • the rubber-like bar bristles 20 are set only into longitudinal edge portions 10b opposed to each other on the bristle-setting surface 10a, and not set into the front end 10c and the end lOd on the handle side.
  • a proper number of bristle bundles 30b prepared harder than the bristle bundles 30a set into the peripheral portion is set into the other portion on the bristle-setting surface 10a, i.e., the central portion so as to achieve a sufficient effect on removal of sordes on teeth.
  • a difference in hardness between the bristle bundles 30b set in the central portion and the bristle bundles 30a set in the peripheral portion is made by suitably varying the resilience, length or thickness of the bristle bundles as described above.
  • materials for the bristle bundles 30a and 30b natural fur or artificial bristles made of nylon, polybutylene terephthalate or the like may be used irrespective of the kind of the material as described above .
  • Fig. 6 illustrates a fifth embodiment, wherein the bases 20a of the rubber-like bar bristles 20 set into the longitudinal edge portions 10b on the bristle-setting surface 10a are connected to each other only on the side of the back surface lOe of the handle head 10 through a connecting member 21.
  • a material for the connecting member 21 may be different from the above-described material for the rubber-like bar bristles 20.
  • Such a toothbrush can be produced with extreme efficiency by fitting a connected member of plural rubberlike bar bristles 20, the bases 20a of which have been connected to each other through the connecting member 21, into through-holes 12 cut in advance in the handle head 10, into which the bristle bundles 30 have been set, from the side of the back surface lOe of the handle head 10 so as to project the bristle parts 20b of the rubber-like bar bristles 20 from the bristle-setting surface 10a, thereby setting the connected member into the handle head 10.
  • the bristle bundles 30 can also be set between the rubber-like bar bristles 20, so that the setting area of the bristle bundles is prevented from being extremely narrowed like the toothbrushes illustrated in Figs. 7A and 7B. Therefore, the toothbrush does not interfere with the effect of the bristle bundles on removal of sordes on teeth, and moreover, a higher gum-massaging effect can be brought about by the rubber-like bar bristles 20.
  • toothbrushes according to the present invention When the toothbrushes according to the present invention are used, a high massaging effect on gums, particularly, peripheries and papillae thereof can be achieved by the elastic sliding action of the rubber-like bar bristles, to say nothing of removal of sordes on teeth. Therefore, the toothbrushes also have an excellent effect on improvement and prevention of gingivitis and the like.
