Definitions
- the present invention relates to a toothbrush where an intermediate area between the brush handle and neck has a weakened portion to cause the toothbrush head to bend relative to the handle when the working pressure on the toothbrush head exceeds a threshold value
- the object of the present invention is to provide a means of giving feedback to the toothbrush user when the force exerted by the toothbrush user on the toothbrush becomes excessive or progressively greater.
- the invention is characterised primarily in that the intermediate section has at least one area of contact for one or more of the toothbrush user's fingers, and that the area of contact has at least two projections or prominent elevations which, in the event that said threshold value is exceeded, either move apart if the area of contact is on the bristle side of the brush, or towards each other if the area of contact is on the back of the brush
- Fig 1 shows a first embodiment of the toothbrush according to the invention
- Fig 2 shows a variant of the toothbrush according to the invention
- Fig 3 shows a further variant of the toothbrush
- the brush is shown having a handle 1, a neck 2 and a head 3.
- an intermediate section 4 between the brush handle 1 and the neck 2 there is a weakened portion 5, 5', 5" that is intended to cause the toothbrush head 3 to be capable of bending relative to the handle 1 when the working pressure on the toothbrush head 3 exceeds a threshold value.
- the intermediate section 4 has at least one area of contact 6 and/or 7 for one or more of the toothbrush user's fingers.
- the area of contact 6 as shown in Fig. 1 has at least two projections or prominent elevations 8, 9. If the said threshold value is exceeded when the toothbrush user brushes too hard, the toothbrush head 3 and the neck 2 will move towards a position as shown in broken lines in Figs.
- projections or elevations 10, 11 may similarly be arranged in connection with the area of contact 7.
- the intermediate section 4 consists of a front part of the toothbrush handle 1 where the cross-section of the first material of the toothbrush is indicated by means of the reference numerals 5, 5', 5", where one or more areas of the weakened portion in the longitudinal direction of the brush are smaller than the otherwise full cross-section of the handle 1.
- the weakened portion 5, 5', 5" is wholly or partly enveloped by a second, elastic material, indicated by the reference numeral 12, which is different from the primary material or first material that forms the handle 1, the weakened portion 5, 5', 5", the neck 2 and the head 3'.
- the projections or elevations 8, 9, optionally the projections or the elevations 10, 11 are uniform with the first material and have their extreme point located immediately below the surface of the second material, in its surface or slightly above its surface.
- the weakened portion preferably consists of a narrow part 5 consisting of the first material of the toothbrush and, unitary with this portion 5 in the bending plane of the narrow part 5, wave-shaped reinforcements 5', 5".
- Said projections or wave crests are provided either in that a projection projects from a respective wave crest, or that at least two wave crests have an amplitude that is markedly greater than the other wave crests, as shown in Figs. 1 and 2, or in a modified version as indicated in Fig. 3.
- Fig. 2 it is shown how when excessive brushing force is exerted on the head 3 the projections or elevations 10, 11 will move towards each other.
- the present invention thus provides a toothbrush where the toothbrush user, with sensitive finger tip areas, will easily be able to feel when the toothbrush user exerts excessive pressure on his teeth during the brushing thereof.
- the first material is preferably a relatively rigid plastic material
- the second material is a softer plastic material that bonds well to the first material.
- the first and second materials may, e.g., be of the type used today in dual material toothbrushes.
