Definitions
- Electric toothbrushes are well known m the art and typically comprise a motor element housed within the brush handle and a head, which is usually replaceable.
- oscillating brushes there is a multitude of oscillating brushes on the market and some have particular oscillating patterns, e.g. longitudinally oscillating elements, or they may have multiple brush heads, such as that marketed by Phillips under the tradename 'Plaque Remover ® ', which comprises a rotating head and a laterally oscillating array of bristles distal to the brush handle.
- oscillating patterns e.g. longitudinally oscillating elements
- multiple brush heads such as that marketed by Phillips under the tradename 'Plaque Remover ® ', which comprises a rotating head and a laterally oscillating array of bristles distal to the brush handle.
- An example of a vibrating brush is that sold by J&J under the tradename ⁇ Powerbrush ® ' .
- a disadvantage of oscillating brushes is that the electrical devices required to effect a proper brushing of the teeth comprise expensive technology.
- a disadvantage of the vibrating brushes, which are usually cheaper, is that they have to vibrate considerably to effect any kind of cleaning benefit. Such vibration is often uncomfortable for the user as the handle often vibrates as much as the head.
- An object of the present invention is to provide a cheap electric toothbrush, which provides an improved cleaning benefit and is easy and comfortable to use.
- the head part of an electric toothbrush comprises a bristle bearing section and a neck portion connecting the bristle bearing section to the handle.
- the head is segmented to provide flexibility. While there may be any number of segments on such a segmented brush head each segment may be unitary with any of a number of other segments or be linked to any number of other segments by a further material.
- the head comprises a rubbery material.
- a rubbery material may link the segments of a segmented brush head.
- a flexible head can modify the vibrational character of the brush head m such a way as to either improve the cleaning compared to an oscillating brush or to improve the action of a vibrating brush. It is also possible that the inclusion of a flexible head reduces the output required from the motor element, which m turn may make the brush more comfortable to use and reduce the power requirements, thus reducing battery changing frequency.
- a conventional brush head comprises hard materials, such as polypropylene or polyacrylonit ⁇ le and it may be that the physical dimensions of these materials provide the flexibilty of the head, e.g. the brush head comprises two or more segment which are linked by a hinge which is unitary with the segments.
- the brush head also comprises a rubbery material to provide flexibility. It is also possible for the brush head to be comprised almost entirely of the rubbery material; the more conventional harder materials, such as polypropylene or styrene acrylonitrile, being present to facilitate anchoring of the bristle tufts.
- the rubbery material extends to cover a substantial portion of the neck portion of the head. Depending on the type of rubber this may reduce the incidence of damage to the users gums and lips as the rubber absorbs the vibrations of the motor.
- rubbery By rubbery is meant that the material has some elastic nature. Given that electric toothbrushes vibrate at an extremely high frequency it is anticipated that a high elastic nature is not necessary and a material with a Shore A hardness of less than conventionally used polypropylene is suitable for use m the present invention.
- the rubbery material has a Shore
- Particularly suitable rubbery material include elastome ⁇ c materials such as those described m WO97/20484, the contents of which are incorporated by reference.
- the head of the brush according to the invention is replaceable.
- the invention provides an electric toothbrush with improved sensory benefits .
- the brush according to the invention provides an improved feel m the oral cavity, especially when the brush comprises a rubbery material m the head or neck. This is particularly so when the non-bristle bearing surfaces of the head is significantly covered by a rubbery material and contacts the buccal lining. This sensory benefit is seen as an important consumer positive.
- Figure 2 illustrates a toothbrush head according to the invention which comprises a neck portion of the head (5) and a bristle-bearing portion of the head (4) and a central support (6) which bears bristles and may be made from any conventional toothbrush handle material such as polypropylene or acrylonitrile.
- the bristle-bearing head portion also comprises flexible boots (8) which may be made from the same material as the remainder of the head e.g. polypropylene and serve to locate individual bristle tufts. These boots are linked to the central support (6) by way of flexible hinges (7) which are integral with both boot (8) and central support (6) .
- the handle (not shown) will comprise a motor element to provide vibration.
- Figure 3 illustrates the brush according to figure 2 with elastomer material (9) incorporated around the boots (8) and the central support (6) . This may be achieved using standard injection moulding technology.
- Figure 5 illustrates an embodiment according to figure 4 where the tufts of the boots are embedded in the elastomer
- Figure 6 illustrates a similar embodiment to figure 5 but where the boot tufts are embedded in a boot (10) comprising a material such as polypropylene which may or may not be hingedly linked to the central portion (8) and surrounded with elastomer (9) .
- a boot 10
